Dear Sirs:
                  CalEnergy Company, Inc., a Delaware corporation (the
"Company"), proposes to sell $350,000,000 aggregate principal amount of the
Company's 7.63% Senior Notes due October 15, 2007 (the "Notes"). The Notes are
to be issued pursuant to the Indenture dated as of October 15, 1997 (the "Base
Indenture"), as amended by the First Supplemental Indenture to be dated as of
October 28, 1997 (the "Supplemental Indenture" and, together with the Base
Indenture, the "Indenture"), between the Company and IBJ Schroder Bank & Trust
Company, as trustee (the "Trustee"). This is to confirm the agreement concerning
the purchase of the Notes from the Company by the Underwriters named in Schedule
A hereto (the "Underwriters").

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

                           (a) A registration statement on Form S-3 (No.
         333-32821), including a form of prospectus relating to certain debt and
         equity securities ("Registered Securities") to be issued from time to
         time by the Company, has been filed with the Securities and Exchange
         Commission ("Commission") and has been declared effective under the
         Securities Act of 1933, as amended ("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 Notes. The registration statement, as amended at the
         time of this Agreement, including all material incorporated by
         reference therein, is hereinafter referred to as the "Registration
         Statement," and the form of


                                        1

<PAGE>



         prospectus included in such Registration Statement, as supplemented by
         the prospectus supplement specifically relating to the Notes, 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 distributed
         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 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 ("Exchange Act"), as
         applicable, and the Rules and Regulations, and none of such documents
         contained an untrue statement of a material fact or omitted to state a
         material fact required to be stated therein or necessary to make the
         statements therein 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 owned by the Company (as
         reflected in Schedule C) have been duly and validly authorized 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 Notes 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


                                        3

<PAGE>



         creditors' rights generally and by equitable principles generally; and
         the Notes, 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 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 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
         Notes 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 Notes.

                           (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.

                           (l) The execution, delivery and performance of this
         Agreement, the Base Indenture and the Supplemental Indenture, and the
         issuance and sale of the Notes and the use of the proceeds of the
         offering of the Notes as described in the Prospectus will not (A)
         conflict with 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 as contemplated by the Indenture) upon any
         asset of the Company, any Subsidiary or any Joint Venture pursuant to
         the terms of, or 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 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


                                        4

<PAGE>



         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 Notes under the Act.

                           (m) Except (A) as to state or foreign securities laws
         and (B) consents of third parties which have been obtained, no consent,
         approval, authorization or order of, or filing or registration by the
         Company, any Subsidiary or, to the best of the Company's knowledge, any
         Joint Venture with, any court, governmental agency or third party is
         required for the consummation of the transactions contemplated by this
         Agreement and the Indenture in connection with the issuance and sale of
         the Notes by the Company and the use of the proceeds of the offering of
         the Notes as described in the Prospectus.

                           (n) The Company has full power and authority to
         authorize, issue and sell the Notes as contemplated by this Agreement
         and to execute, deliver and perform this Agreement, the Base Indenture,
         the Supplemental Indenture and the Notes.

                           (o) This Agreement has been duly authorized, executed
         and delivered by the Company.

                           (p) Except as disclosed in or contemplated by the
         Prospectus, the Company, each Subsidiary and each Joint Venture holds,
         as applicable, good and valid title to, or valid and enforceable
         leasehold or contractual interests in, all real properties and all
         other properties and assets owned or leased by or held under contract
         by each of them that are material to the business of the Company, the
         Subsidiaries and the Joint Ventures taken as a whole, and free from
         liens, encumbrances and defects that would materially interfere with
         the use made or to be made thereof by them.

                           (q) Except as disclosed in or contemplated by the
         Prospectus, the Company, the Subsidiaries and the Joint Ventures carry,
         or are covered by, insurance in such amounts and covering such risks as
         is customary for similarly situated companies in the Company's, such
         Subsidiaries' and such Joint Ventures' industries, respectively. Each
         of the foregoing insurance policies is valid and in full force and
         effect, and no event has occurred and is continuing that permits, or
         after notice or lapse of time or both would permit, modifications or
         terminations of the foregoing that, individually or in the aggregate,
         is 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.

                           (r) Except as disclosed in or contemplated by the
         Prospectus, the Company, each Subsidiary and each Joint Venture (i) has
         obtained each license, permit, certificate, franchise or other
         governmental authorization which is material to the ownership of their

         such violations and remedial actions, 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; there has

         contaminants due to or caused by the Company, any Subsidiary or any
         Joint Venture or with respect to which the Company, any Subsidiary or
         any Joint Venture has knowledge, except for any such spill, discharge,
         leak, emission, injection, escape, dumping or release which does not
         have, or would not be reasonably likely to have, individually or in the
         aggregate with all such spills, discharges, leaks, emissions,

         on the financial condition, business or results of operations of the
         Company, the Subsidiaries and the Joint Ventures taken as a whole; and
         the terms "hazardous wastes", "toxic wastes" and "hazardous substances"

         each of the Company, each Subsidiary and each Joint Venture is not and,
         after giving effect to the offering and sale of the Notes and the
         application of the proceeds thereof as described in the Prospectus,

         Company after due inquiry, a company controlled by an "investment
         company" within the meaning of the 1940 Act.

                           (ac) The Company, each Subsidiary and each Joint
         Venture has filed all federal, state and local income and franchise tax

         Venture that has had (nor does the Company have any knowledge of any
         tax deficiency which, if determined adversely to the Company, any
         Subsidiary or any Joint Venture would be 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.

                           (ad) The financial statements and the related notes
         and schedules included or incorporated by reference in the Registration
         Statement and Prospectus fairly present the financial position, the
         results of operations and the cash flows of the Company and its
         consolidated subsidiaries at the respective dates and for the
         respective periods to which they apply; and such financial statements
         and the related notes and schedules have been prepared in conformity
         with United States generally accepted accounting principles applied on
         a consistent basis throughout the periods therein specified. The
         historical information under the caption "Capitalization" in the
         Prospectus is accurately described as of the date presented therein.

                           (ae) Since the date of the latest financial
         statements included or incorporated by reference in the Prospectus (i)

         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 or contemplated by the Prospectus, there have not 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 to the Company, the Subsidiaries and the Joint
         Ventures taken as a whole; and, except as disclosed in the Prospectus,
         there has been no dividend or distribution of any kind declared, paid
         or made by the Company on any class of its capital stock.

                           (af) The pro forma financial information included in
         the Registration Statement and the Prospectus presents fairly the
         information shown therein, has been prepared in accordance with the
         Commission's rules and guidelines with respect to pro forma financial
         information, has been properly compiled on the pro forma bases
         described therein, and, in the opinion of the Company, the assumptions
         used in the preparation thereof are reasonable and the adjustments used
         therein are appropriate to give effect to the transactions or
         circumstances referred to therein.

                           (ag) The accountants who have certified certain
         financial statements of the Company or of businesses acquired by the
         Company, as applicable, and whose reports appear in the Registration
         Statement and the Prospectus or are incorporated by reference therein,

         5.       Further Agreements of the Company.  The Company agrees:

                  (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


                                       11

<PAGE>



         following the execution and delivery of this Agreement. The Company
         will advise Lehman 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
         Prospectus and will not effect such amendment or supplementation
         without the Representatives' prior consent, which consent shall not be
         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 Notes 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.

                  (d) As soon as practicable, but not later than 16 months after
         the date of this Agreement, the Company will make generally available
         to its securityholders an earnings statement (which need not be
         audited) covering a period of at least 12 months beginning after the
         later of (i) the effective date of the most recent post-effective
         amendment to the Registration Statement to become effective prior to
         the date of this Agreement and (ii) the date of the Company's most
         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 (four of which will be signed and will
         include all exhibits), each preliminary prospectus and preliminary
         prospectus supplement relating to the Notes, and, so long as delivery
         of a prospectus relating to the Notes 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.

                  (f) The Company will arrange for the qualifications of the
         Notes 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 Notes or to
         taxation in respect of doing business in any jurisdiction in which it
         is not otherwise 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
         year, a copy of its annual report to stockholders for such year; and
         the Company will furnish to the Representatives as soon as available, a
         copy of each report and any definitive proxy statement of the Company
         filed with the Commission under the Exchange Act or mailed to
         stockholders.

                  (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
         Notes and on the execution and delivery of this Agreement. All payments
         to be made by the Company hereunder shall be made without withholding
         or deduction for or on account of any present or future taxes, duties
         or governmental charges whatsoever unless the Company is compelled by
         law to deduct or withhold such taxes, duties or charges. In that event,
         the Company shall pay such additional amounts as may be necessary in
         order that the net amounts received after such withholding or deduction
         shall equal the amounts that would have been received 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.

                  (j) No action has been or, prior to the completion of the
         distribution of the Notes, will be taken by the Company in any
         jurisdiction outside the United States that would permit a public
         offering of the Notes, 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 Notes, 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 authorization, issuance, sale and delivery of the Notes and will
reimburse the Underwriters (if and to the extent necessary) for any travel
expenses of the Company's officers and employees and other expenses of the
Company in connection with attending or hosting meetings with prospective
purchasers of the Notes ; (b) the costs incident to the preparation, printing
and filing under the Securities Act of the Registration Statement and any
amendments and exhibits thereto;


                                       13

<PAGE>



(c) the costs of distributing any preliminary prospectus, preliminary prospectus
supplement, the Prospectus and any amendment or supplement thereto or any
document incorporated by reference therein, all as provided in this Agreement;
(d) the costs of producing and distributing this Agreement, the Base Indenture,
the Supplemental Indenture and any other related documents in connection with
the offering, purchase, sale and delivery of the Notes; (e) any rating agency
fees; and (f) all other costs and expenses incident to the performance of the
obligations of the Company under this Agreement; provided that, except as
provided in this Section 6 and in Section 11, the Underwriters shall pay their
own costs and expenses, including the costs and expenses of their counsel, any
transfer taxes on the Notes which they may sell and the expenses of advertising
any offering of the Notes made by the Underwriters.

                  7. Conditions of Underwriters' Obligations. The respective
obligations of the Underwriters hereunder are subject to the accuracy, when made
and on the Delivery Date, of the representations and warranties of the Company
contained herein, to the performance by the Company of its obligations
hereunder, and to each of the following additional terms and conditions:

                  (a) On or prior to the date of this Agreement, the
         Representatives shall have received a letter, dated the date of
         delivery thereof, of Deloitte & Touche LLP (and the independent
         accountants of any subsidiary of the Company or of any business
         acquired by the Company for which financial statements and financial
         data are included or incorporated by reference in the Prospectuses) in
         agreed form.

                  All financial statements and schedules included in material
         incorporated by reference into the Registration Statement and the
         Prospectus shall be deemed included in the Registration Statement and
         the Prospectuses for purposes of this subsection.

                  (b) The Prospectus shall have been filed with the Commission
         in accordance with the Rules and Regulations and Section 5(a) of this
         Agreement. Prior to the Delivery Date, no stop order suspending the
         effectiveness of the Registration Statement shall have been issued and
         no proceedings for that purpose shall have been instituted or, to the
         knowledge of the Company or the Representatives, shall be contemplated
         by the Commission.

                  (c) Subsequent to the execution and delivery of this
         Agreement, there shall not have occurred (i) any change, or any
         development or event involving a prospective change in the financial
         condition, business or 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 completion of the public offering or the
         sale of and payment for the Notes; (ii) any downgrading in the rating
         of any debt securities or preferred stock of the Company by any
         "nationally recognized statistical rating organization" (as defined for
         purposes of Rule 436(g) under the Act), or any public announcement that
         any such organization has under surveillance or review


                                       14

<PAGE>



         its rating of any debt securities or preferred stock of the Company
         (other than an announcement with positive implications of a possible
         upgrading, and no implication of a possible downgrading, of such
         rating); (iii) any suspension or limitation of trading in securities
         generally on the New York Stock Exchange or any setting of minimum
         prices for trading on such 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 escalation of
         major hostilities in which the United States is involved, any
         declaration of war by the United States Congress or any other
         substantial national or international calamity or emergency if, in the
         judgment of a majority in interest of the Underwriters including the
         Representatives, the effect of any such outbreak, escalation,
         declaration, calamity or emergency on the financial markets makes it
         impracticable or inadvisable to proceed with completion of the public
         offering or the sale of and payment for the Notes.

                  (d) The Representatives shall have received an opinion, dated
         the Delivery Date, of Steven A. McArthur, Senior Vice President and
         General Counsel of the Company, to the effect that:

                           (i) Each of the Company, the Subsidiaries and the
                  Joint Ventures has been duly organized and is validly existing
                  and, if applicable, in good standing under the laws of its
                  respective jurisdiction of organization and each of the
                  Company, the Subsidiaries and the Joint Ventures has the power
                  and authority to own, lease and operate its respective
                  properties and to conduct its businesses as described in the
                  Prospectus;

                           (ii) Each of the Company, the Subsidiaries and the
                  Joint Ventures is duly registered or qualified to do business
                  and (to the extent applicable) is in good standing as a
                  foreign corporation, a foreign 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 Subsidiaries 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 Prospectus; to the best knowledge of such counsel, 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 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, encum-


                                       15

                  brances 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 contemplated
                  by the Prospectus, are owned beneficially by the Company free
                  and clear of any material claims, liens, encumbrances and
                  security interests;

                           (iv) Each of the Base Indenture and the Supplemental
                  Indenture has been duly and validly authorized, executed and
                  delivered by the Company and constitutes the legal, valid and
                  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 transfers),
                  reorganization or other laws relating to or affecting
                  creditors' rights generally and except as enforcement thereof
                  is subject to general principles of equity (regardless of
                  whether enforcement is considered in a proceeding in equity or
                  at law);

                           (v) The Notes have been validly authorized by the
                  Company, and, assuming due authorization 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 laws relating to fraudulent transfers),
                  reorganization, moratorium or other laws relating to or
                  affecting creditors' rights generally and except as
                  enforcement thereof is subject to general principles of equity
                  (regardless of whether enforcement is considered in a
                  proceeding in equity or at law);

                           (vi) The statements in the Prospectus under the
                  captions "Description of the Notes" and "Description of Debt
                  Securities," insofar as they purport to summarize the
                  provisions of the Indenture and the Notes, 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 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;

                           (viii) To such counsel's knowledge, there are no
                  contracts, agreements or understandings which have not been
                  satisfied or waived between the Company and any person
                  granting such person the right to require the Company to file
                  a registration statement under the Act with respect to any
                  securities of the Company


                                       16

<PAGE>



                  owned or to be owned by such person or to require the Company
                  to include any such securities in the securities registered
                  pursuant to the Registration Statement or in any securities
                  being registered pursuant to any other registration 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
                  properties and all other properties and assets owned or leased
                  by each of them that are material to the business of each such
                  entity, in each case free from all liens, encumbrances, and
                  defects that would materially interfere with the use made or
                  to be made thereof by them;

                           (x) To such counsel's knowledge, there is no legal or
                  governmental action, suit or proceeding before any court,
                  governmental agency, body or authority, domestic or foreign,
                  now pending, threatened against, or involving, the Company,
                  any Subsidiary or any Joint Venture (i) of a character
                  required to be disclosed in the Registration Statement which
                  is not adequately disclosed in the 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 Notes;

                           (xi) To such counsel's knowledge, the Company, each
                  Subsidiary and each Joint Venture (i) has obtained each
                  license, permit, certificate, franchise or other governmental
                  authorization which is material to the ownership of their
                  properties or to the conduct of 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) in either case
                  where the failure to do so is not 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, (y) permits, consents and approvals that may be
                  required for future drilling or operating activities which are
                  ordinarily deemed to be ministerial in nature and which are
                  anticipated to be obtained in the ordinary course and (z)
                  permits, consents and approvals for developmental or
                  construction activities which have not yet been obtained but
                  which have been or will be applied for in the course of
                  development or construction and which are anticipated to be
                  obtained in the ordinary course;

                           (xii) The Company has all requisite corporate power
                  and authority to enter into this Agreement, the Base Indenture
                  and the Supplemental Indenture, to

                  issue the Notes and to consummate the transactions 
                  contemplated by this Agreement, the Indenture and the Notes;

                           (xiii) There are no contracts or other documents
                  which are required to be described in the Prospectus or filed
                  as exhibits to the Registration Statement by the Act or by the
                  Rules and Regulations which have not been described or filed
                  as exhibits to the Registration Statement or incorporated by
                  reference therein as permitted by the Rules and Regulations;

                           (xiv) This Agreement has been duly authorized,
                  executed and delivered by the Company;

                           (xv) (A) The execution, delivery and performance of
                  this Agreement, the Indenture, the issuance and sale of the
                  Notes and the use of proceeds of the Notes as designated in
                  the Prospectus do not and will not (i) conflict with the
                  corporate charter or by-laws or partnership agreement of the
                  Company, any Subsidiary or any Joint Venture, (ii) to the best
                  knowledge of such counsel (except as contemplated by the
                  Indenture), conflict with, result in the creation or
                  imposition of any lien, charge or other encumbrance upon any
                  asset of the Company, any Subsidiary or any Joint Venture
                  pursuant to the terms of, or 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 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
                  (iii) to the best knowledge of such counsel, 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
                  conflict, encumbrance, breach, default or violation under
                  clauses (ii) or (iii), individually or in the aggregate, is
                  reasonably likely to have a material adverse effect on the
                  financial condition, business or results of operations of the
                  Company, its Subsidiaries and the Joint Ventures taken as a
                  whole; (B) to the knowledge of such counsel, except for (i)
                  the registration of the Notes under the Act and the
                  qualification of the Indenture under the Trust Indenture Act

                  Company, the Subsidiaries and the Joint Ventures taken as a
                  whole, or on the Notes or the ability of the Company to
                  perform its obligations under this Agreement, the Indenture
                  and the Notes and (C) the Company has full corporate power and
                  authority to authorize, issue and sell the Notes as
                  contemplated by this Agreement and the Indenture;

                           (xvi) The Company is not required to be registered
                  under the Investment Company Act of 1940, as amended;

                           (xvii) The documents incorporated by reference in the
                  Prospectus and any further amendments or supplements to any
                  such incorporated document made by the Company prior to the
                  Delivery Date (other than the financial statements, related
                  schedules and other financial and statistical information
                  contained therein or omitted therefrom as to which such
                  counsel need express no opinion), when they became effective
                  or were filed with the Commission, as the case may be, appear
                  on their face to have been appropriately responsive in all
                  material respects to the applicable requirements of the Act or
                  the Exchange Act, as the case may be, and the Rules and
                  Regulations of the Commission thereunder; and

                  (e) The Company shall have furnished to the Representatives
         the opinion of Willkie Farr & Gallagher, special counsel to the
         Company, addressed to the Underwriters and dated the Delivery Date, in
         form and substance satisfactory to the Representatives, to the effect
         that:

                           (i) The Company has been duly organized and is
                  validly existing and in good standing under the laws of its
                  jurisdiction of organization and the Company has the corporate
                  power and authority to own, lease and operate its properties
                  and to conduct its businesses as described in the Prospectus;

                           (ii) Such counsel has been advised by the Commission
                  that the Registration Statement has been declared effective
                  under the Act; the Prospectus has been filed with the
                  Commission pursuant to the appropriate subparagraph of Rule
                  424(b) of the Rules and Regulations; to the best knowledge of
                  such counsel, no stop order suspending the effectiveness of
                  the Registration Statement has been issued and no proceeding
                  for that purpose is pending or threatened by the Commission;

                           (iii) The Registration Statement, as of its effective
                  date, the Registration Statement and the Prospectus, as of the
                  date of this Agreement, and any further amendments or
                  supplements thereto made by the Company prior to the Delivery
                  Date (in each case, other than the financial statements,
                  related schedules, other financial and statistical information
                  contained therein or omitted therefrom as to which such
                  counsel need express no opinion) as of their effective dates,
                  appear on their face to have been appropriately responsive in
                  all material respects to the

                  applicable requirements of the Act, the Exchange Act and the
                  Rules and Regulations;

                           (iv) Each of the Base Indenture and the Supplemental
                  Indenture has been duly and validly authorized, executed and
                  delivered by the Company and constitutes the valid and binding
                  obligation of the Company, enforceable against the Company in
                  accordance with its terms, except as enforcement may be
                  limited by bankruptcy, insolvency (including, without
                  limitation, all laws relating to fraudulent transfers),
                  reorganization or other similar laws affecting creditors'
                  rights generally and except as enforcement thereof is subject
                  to general principles of equity (regardless of whether
                  enforcement is considered in a proceeding in equity or at
                  law); and the Indenture conforms as to legal matters in all
                  material respects to the description thereof contained in the
                  Prospectus;

                           (v) The Notes have been validly authorized by the
                  Company, and, 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
                  (including, without limitation, all laws relating to
                  fraudulent transfers), reorganization or other similar laws
                  relating to or affecting creditors' rights generally and
                  except as enforcement thereof is subject to general principles
                  of equity (regardless of whether enforcement is considered in
                  a proceeding in equity or at law); and the Notes conform as to
                  legal matters in all material respects to the description
                  thereof contained in the Prospectus;

                           (vi) To such counsel's knowledge, there are no
                  contracts or other documents which are required to be
                  described in the Prospectus or filed as exhibits to the
                  Registration Statement by the Act or by the Rules and
                  Regulations which have not been described or filed as exhibits
                  to the Registration Statement or incorporated by reference
                  therein as permitted by the Rules and Regulations;

                           (vii) This Agreement has been duly authorized,
                  executed and delivered by the Company; and

                           (viii) No consent, authorization, order of, or filing
                  or registration by the Company with, any United States
                  governmental authority or body having jurisdiction over the
                  Company is necessary or required for the performance by the
                  Company of its obligations under this Agreement, the Indenture
                  or the Notes or in connection with the issuance and sale of
                  the Notes hereunder or thereunder, except as may be required
                  under applicable state or foreign securities laws or blue sky
                  laws in connection with the purchase and distribution of the
                  Notes.

                  (f) In the rendering of the opinions described in Section 7(d)
         and Section 7(e) above, such counsel may (i) state that their opinion
         is limited to matters governed by the Federal laws of the United States
         of America, the laws of the State of New York and the General
         Corporation Law of the State of Delaware and (ii) rely, to the extent
         they deem proper, in respect of matters of fact, upon certificates and
         representations of officers of the Company, the Subsidiaries or the
         Joint Ventures and public officials. Such counsel shall also have
         furnished to the Representatives a written statement, addressed to the
         Underwriters and dated the Delivery Date, in form and substance
         reasonably satisfactory to the Representatives, to the effect 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 Notes) 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
         Registration Statement, the Prospectus, any amendment thereof or
         supplement thereto, and (ii) based on the foregoing, no facts have come
         to the attention of such counsel which cause them to believe that
         (except for the financial statements, related schedules and other
         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 (other than the documents incorporated
         by reference therein), 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.

                  (g) The Representatives shall have received from Skadden,
         Arps, Slate Meagher & Flom LLP, counsel for the Underwriters, such
         opinion or opinions, dated the Delivery


                                       21

<PAGE>



         Date, with respect to the issuance and sale of the Notes, the
         Registration 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.

                  (h) 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.

                  (i) 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.

                  (j) 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
         Notes 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 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 Notes), 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 dated September 22, 1997, as supplemented
by the Preliminary Prospectus Supplement dated October 8, 1997 (as supplemented,
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 Notes 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 Notes. For purposes of the last proviso to the
immediately preceding sentence, the term "Prospectus" shall not be deemed to
include the documents incorporated by reference therein, and no Underwriter
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.

<PAGE>



                  (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 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


                                       24

the Company in connection with the defense of such action or, if in the written
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 Notes 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 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 Notes 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 Notes 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


                                       25

<PAGE>



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 Notes 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
Notes 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.


                  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 Notes which the
defaulting Underwriter agreed but failed to purchase on the Delivery Date in the
respective proportions which the principal amount of the Notes set opposite the
name of each remaining non-defaulting Underwriter in Schedule 1 hereto bears to
the aggregate principal amount of the Notes set opposite the names of all the
remaining non-defaulting Underwriters in Schedule 1 hereto; provided, however,
that the remaining non-defaulting Underwriters shall not be obligated to
purchase any of the Notes on the Delivery Date if the aggregate principal amount
of the Notes which the defaulting Underwriter or Underwriters agreed but failed
to purchase on such date exceeds 10% of the aggregate principal amount of the
Notes 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 Notes 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 Notes 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 Notes which the
defaulting Underwriter or Underwriters agreed but


                                       26

<PAGE>



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 1 hereto
who, pursuant to this Section 9, purchases Notes 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 Notes
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 Notes if, prior to that time,
any of the events described in Sections 7(c) or 7(j), shall have occurred or if
the Underwriters shall decline to purchase the Notes for any reason permitted
under this Agreement.

                  11. Reimbursement of Underwriters' Expenses. If the Company
shall fail to tender the Notes 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 Notes 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

                           (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

be entitled to act and rely upon any request, consent, notice or agreement given
or made on behalf of the Underwriters by Lehman 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 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 Notes 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
courts of the State of New York in each case located in the Borough of Manhattan

submits to the exclusive jurisdiction (except for proceedings instituted in
regard to the enforcement of a judgment of any such court (a "Related
Judgment"), as to which such


                                       28

jurisdiction is non-exclusive) of such courts in any such suit, action or
proceeding. The parties further agree that service of any process, summons,

and agree not to plead or claim in any such court that any such lawsuit, action
or other proceeding brought in any such court has been brought in an
inconvenient forum.

                  17. Counterparts. This Agreement may be executed in one or
more counterparts and, if executed in more than one counterpart, the executed
counterparts shall each be deemed to be an original but all such counterparts
shall together constitute one and the same instrument.

evidencing its unsecured and unsubordinated indebtedness, and has duly
authorized the execution and delivery of this Indenture to provide for the

Company, in accordance with its terms, have been done.

         NOW, THEREFORE, THIS INDENTURE WITNESSETH:

         For and in consideration of the premises and the purchase of the
Securities by the Holders thereof, it is mutually covenanted and agreed, for the
equal and proportionate benefit of all Holders of the Securities, as follows:

    as amended from time to time.

         Whenever this Indenture requires that a particular ratio or amount be

         "Adjusted Consolidated Net Income" means for any period, for any Person

all the Property of such other Person is acquired by the Referenced Person or
any of its Subsidiaries, (iii) the Net Income (if positive) of any Subsidiary of

Unrestricted Subsidiaries), (v) the cumulative effect of a change in accounting
principles and (vi) any amounts paid or accrued as dividends on Preferred Stock

directly or indirectly, of the power to direct or cause the direction of the
management and policies of such Person, whether through the ownership of voting

to any Person (other than to the Company, a Restricted Subsidiary of the Company
or an Eligible Joint Venture and other than in the ordinary course of business)
of any Property of the Company, any of its Restricted Subsidiaries or any
Eligible Joint Venture other than any shares of Capital Stock of the
Unrestricted Subsidiaries. Notwithstanding the foregoing to the contrary, the
term "Asset Disposition" shall include the sale, transfer,




                                       4

Subsidiary pursuant to clause (vii) of the definition of "Permitted Payment,"
and the Company shall, and shall cause each of its Restricted Subsidiaries and
Eligible Joint Ventures to, apply pursuant to Section 1015 that portion of the
Net Cash Proceeds from the sale, transfer, conveyance or other disposition of
such Unrestricted Subsidiary that is equal to the portion of the total
Investment in such Unrestricted Subsidiary that is represented by the Investment
that was made pursuant to clause (vii) of the definition of "Permitted Payment."

qualifying shares or investments by foreign nationals mandated by applicable law
shall not constitute an Asset Disposition. In addition, the term "Asset
Disposition" shall not include (i) any sale, transfer, conveyance, lease or
other disposition of the Capital Stock or Property of Restricted Subsidiaries or
Eligible Joint Ventures pursuant to the terms of any power sales agreements or
steam sales agreements to which such Restricted Subsidiaries or such Eligible
Joint Ventures are parties on the Issue Date of the Securities or pursuant to
the terms of any power sales agreements or steam sales agreements, or other
agreements or contracts that are related to the output or product of, or
services rendered by, a Permitted Facility as to which such Restricted
Subsidiary or such Eligible Joint Venture is the supplying party, to which such
Restricted Subsidiaries or such Eligible Joint Ventures become a party after
such date if the President or Chief Financial Officer of the Company determines
in good faith (evidenced by an Officers' Certificate) that such provisions are
customary (or, in the absence of any industry custom, reasonably necessary) in
order to effect such agreements and are reasonable in light of comparable
transactions in the applicable jurisdiction, (ii) any sale, transfer,
conveyance, lease or other disposition of Property governed by Section 801,
(iii) any sale, transfer, conveyance, lease or other disposition of any Cash
Equivalents, (iv) any transaction or series of related transactions consisting

insubstantial portion of the prospective Construction Financing that would be
required to commence commercial operation has been funded or (iv) transactions
determined in good faith by the Chief Financial Officer, as evidenced by an
Officers' Certificate, made in order to enhance the repatriation of the Net Cash
Proceeds for a Foreign Asset Disposition or in order to increase the after-tax
proceeds thereof available for immediate distribution to the Company. Any Asset
Disposition that results from the bona fide exercise by any governmental
authority of its claimed or actual power of eminent domain need not comply with

that results from a casualty loss need not comply with the provisions of clause

U.S. Government Obligation or the specific payment of interest on or principal
of the U.S. Government Obligation evidenced by such depositary receipt.

         SECTION 102.  Compliance Certificates and Opinions.
                       ------------------------------------

         Upon any application or request by the Company to the Trustee to take
any action under any provision of this Indenture, the Company shall furnish to
the Trustee such certificates and opinions as may be required under the Trust
Indenture Act. Each such certificate or opinion shall be given in the form of an
Officers' Certificate, if to be given by officers of the Company, or an Opinion
of Counsel, if to be given by counsel, and shall comply with the requirements of
the Trust Indenture Act and any other requirement set forth in this Indenture.

         Every certificate or opinion with respect to compliance with a
condition or covenant provided for in this Indenture shall include:

         (1) a statement that each individual signing such certificate or
    opinion has read such covenant or condition and the definitions herein
    relating thereto;

         (2) a brief statement as to the nature and scope of the
         examination or investigation upon which the statements or opinions
         contained in such certificate or opinion are based;

         (3) a statement that, in the opinion of each such individual, he has
    made such examination or investigation as is necessary to enable him to
    express an informed opinion as to whether or not such covenant or condition
    has been complied with; and

         (4) a statement as to whether, in the opinion of each such individual,
    such condition or covenant has been complied with.

         SECTION 103.  Form of Documents Delivered to Trustee.
                       --------------------------------------

         If several matters are required to be certified by, or covered by an
opinion of, any specified Person, it is not




                                       34
<PAGE>


necessary that all such matters be certified by, or covered by the opinion of,
only one such Person, or that they be so certified or covered by only one
document, but one such Person may certify or give an opinion with respect to
some matters and one or more other such Persons as to other matters, and any
such Person may certify or give an opinion as to such matters in one or several
documents.

         Any certificate or opinion of an officer of the Company may be based,
insofar as it relates to legal matters, upon a certificate or opinion of, or
representations by, counsel, unless such officer knows, or in the exercise of
reasonable care should know, that the certificate or opinion or representations
with respect to the matters upon which his certificate or opinion is based are
erroneous. Any such certificate or opinion of counsel may be based, insofar as
it relates to factual matters, upon a certificate or opinion of, or
representations by, an officer or officers of the Company stating that the
information with respect to such factual matters is in the possession of the
Company, unless such counsel knows, or in the exercise of reasonable care should
know, that the certificate or opinion or representations with respect to such
matters are erroneous.

         If any Person is required to make, give or execute two or more
applications, requests, consents, certificates, statements, opinions or other
instruments under this Indenture, they may, but need not, be consolidated and
form one instrument.

         SECTION 104.  Acts of Holders; Record Dates.
                       -----------------------------

         Any request, demand, authorization, direction, notice, consent, waiver
or other action provided or permitted by this Indenture to be given or taken by
Holders of the Outstanding Securities of all series or one or more series, as
the case may be, may be embodied in and evidenced by one or more instruments of
substantially similar tenor signed by such Holders in person or by an agent duly
appointed in writing. Except as herein otherwise expressly provided, such action
shall become effective when such instrument or instruments are delivered to the
Trustee and, if it is hereby expressly required, to the Company. Such instrument
or instruments (and the action embodied therein and evidenced thereby) are
herein sometimes referred to as the "Act" of the Holders signing such instrument
or instruments. Proof of execution of any such instrument or of a writing
appointing any such agent shall be sufficient for any purpose of this Indenture
and (subject to Section 601) conclusive in favor of the Trustee and the Company,
if made in the manner provided in this Section 104.




                                       35
<PAGE>


         The fact and date of the execution by any Person of any such instrument
or writing may be proved by the affidavit of a witness of such execution or by a
certificate of a notary public or other officer authorized by law to take
acknowledgments of deeds, certifying that the individual signing such instrument
or writing acknowledged to him the execution thereof. If such execution is by a
signer acting in a capacity other than his individual capacity, such certificate
or affidavit shall also constitute sufficient proof of his authority. The fact
and date of the execution of any such instrument or writing, or the authority of
the Person executing the same, may also be proved in any other manner that the
Trustee deems sufficient.

         The ownership of Securities shall be proved by the Security register
kept by the Security Registrar.

         Any request, demand, authorization, direction, notice, consent, waiver
or other Act of the Holder of any Security shall bind every future Holder of the
same Security and the Holder of every Security issued upon the registration of
transfer thereof or in exchange therefor or in lieu thereof in respect of
anything done, omitted or suffered to be done by the Trustee, or the Company in
reliance thereon, whether or not notation of such action is made upon such
Security.

         The Company may set any day as a record date for the purpose of
determining the Holders of Outstanding Securities entitled to give or take any
request, demand, authorization, direction, notice, consent, waiver or other
action provided or permitted by this Indenture to be given or taken by Holders
of Securities, provided that the Company may not set a record date for, and the
provisions of this paragraph shall not apply with respect to, the giving or
making of any notice, declaration, request or direction referred to in the next
paragraph. If any record date is set pursuant to this paragraph, the Holders of
Outstanding Securities on such record date, and no other Holders, shall be
entitled to take the relevant actions whether or not such Holders remain Holders
after such record date; provided that no such action shall be effective
hereunder unless taken on or prior to the applicable Record Expiration Date by
Holders of the requisite principal amount of Outstanding Securities on such
record date; and provided further that for the purpose of determining whether
Holders of the requisite principal amount of such Securities have taken such
action, no Security shall be deemed to have been Outstanding on such record date
unless it is also Outstanding on the date such action is to become effective.
Nothing in this paragraph shall prevent the Company from setting a new record
date for any action for which a record date has previously been set pursuant to
this paragraph (whereupon the record date previously set shall automatically and
with no action




                                       36
<PAGE>


by any Person be cancelled and of no effect), nor shall anything in this
paragraph be construed to render ineffective any action taken by Holders of the
requisite principal amount of Outstanding Securities on the date such action is
taken. Promptly after any record date is set pursuant to this paragraph, the
Company, at its own expense, shall cause notice of such record date, the
proposed action by Holders and the applicable Record Expiration Date to be given
to the Trustee in writing and to each Holder of Securities in the manner set
forth in Section 106.

         The Trustee may set any day as a record date for the purpose of
determining the Holders of Outstanding Securities entitled to join in the giving
or making of (i) any Notice of Default, (ii) any declaration of acceleration
referred to in Section 502, (iii) any request to institute proceedings referred
to in Section 507(2) or (iv) any direction referred to in Section 512. If any
record date is set pursuant to this paragraph, the Holders of Outstanding
Securities on such record date, and no other Holders, shall be entitled to join
in such notice, declaration, request or direction, whether or not such Holders
remain Holders after such record date; provided that no such action shall be
effective hereunder unless taken on or prior to the applicable Record Expiration
Date by Holders of the requisite principal amount of Outstanding Securities on
such record date; and provided further that for the purpose of determining
whether Holders of the requisite principal amount of such Securities have taken
such action, no Security shall be deemed to have been Outstanding on such record
date unless it is also Outstanding on the date such action is to become
effective. Nothing in this paragraph shall be construed to prevent the Trustee
from setting a new record date for any action (whereupon the record date
previously set shall automatically and without any action by any Person be
cancelled and of no effect), nor shall anything in this paragraph be construed
to render ineffective any action taken by Holders of the requisite principal
amount of Outstanding Securities on the date such action is taken. Promptly
after any record date is set pursuant to this paragraph, the Trustee, at the
Company's expense, shall cause notice of such record date, the matter(s) to be
submitted for potential action by Holders and the applicable Record Expiration
Date to be given to the Company in writing and to each Holder of Securities in
the manner set forth in Section 106.

         With respect to any record date set pursuant to this Section 104, the
party hereto that sets such record date may designate any day as the "Record
Expiration Date" and from time to time may change the Record Expiration Date to
any earlier or later day, provided that no such change shall be effective unless
notice of the proposed new Record Expiration Date is given to the other party
hereto in writing, and to each Holder of Securities





                                       37
<PAGE>


in the manner set forth in Section 106, on or before the existing Record
Expiration Date. If a Record Expiration Date is not designated with respect to
any record date set pursuant to this Section 104, the party hereto that set such
record date shall be deemed to have initially designated the 180th day after
such record date as the Record Expiration Date with respect thereto, subject to
its right to change the Record Expiration Date as provided in this paragraph.
Notwithstanding the foregoing, no Record Expiration Date shall be later than the
180th day after the applicable record date.

         Without limiting the foregoing, a Holder entitled hereunder to take any
action hereunder with regard to any particular Security may do so with regard to
all or any part of the principal amount of such Security or by one or more duly
appointed agents each of which may do so pursuant to such appointment with
regard to all or any part of such principal amount.

         SECTION 105.  Notices, Etc., to Trustee and Company.
                       -------------------------------------

         Any request, demand, authorization, direction, notice, consent, waiver
or Act of Holders or other document provided or permitted by this Indenture to
be made upon, given or furnished to, or filed with,

         (1) the Trustee by any Holder or by the Company shall be sufficient for
    every purpose hereunder if made, given, furnished or filed in writing and
    mailed, first-class postage prepaid, to or with the Trustee at its Corporate
    Trust Office, Attention: Corporate Trust Administration, or

         (2) the Company by the Trustee or by any Holder shall be sufficient for
    every purpose hereunder (unless otherwise herein expressly provided) if in
    writing and mailed, first-class postage prepaid, to the Company addressed to
    it at the address of its principal office specified in the first paragraph
    of this Indenture, Attention: General Counsel, or at any other address
    previously furnished in writing to the Trustee by the Company.

         SECTION 106.  Notice to Holders; Waiver.
                       -------------------------

         When this Indenture provides for notice to Holders of any event, such
notice shall be sufficiently given (unless otherwise herein expressly provided)
if in writing and mailed, first-class postage prepaid, to each Holder affected
by such event, at such Holder's address as it appears in the Security Register,
not later than the latest date (if any), and not earlier than the earliest date
(if any), prescribed for the




                                       38
<PAGE>



giving of such notice. Neither the failure to mail or give such notice as
otherwise provided herein, nor any defect in any notice so mailed or given to
any particular Holder shall affect the sufficiency of such notice with respect
to other Holders. When this Indenture provides for notice in any manner, such
notice may be waived in writing by the Person entitled to receive such notice,
either before or after the event, and such waiver shall be the equivalent of
such notice. Waivers of notice by Holders shall be filed with the Trustee, but
such filing shall not be a condition precedent to the validity of any action
taken in reliance upon such waiver.

         In case by reason of the suspension of regular mail service or by
reason of any other cause it shall be impracticable to give such notice by mail,
then such notification as shall be made with the approval of the Trustee shall
constitute a sufficient notification for every purpose hereunder.

         SECTION 107.  Conflict with Trust Indenture Act.
                       ---------------------------------

         If any provision hereof limits, qualifies or conflicts with a provision
of the Trust Indenture Act that is required under such Act to be part of and
govern this Indenture, the latter provision shall control. If any provision of
this Indenture modifies or excludes any provision of the Trust Indenture Act
that may be so modified or excluded, the latter provision shall be deemed to
apply to this Indenture as so modified or to be excluded, as the case may be.

         SECTION 108.  Effect of Headings and Table of Contents.
                       ----------------------------------------

         The Article and Section headings herein, the Cross-Reference Table and
the Table of Contents are for convenience only and shall not affect the
construction hereof.

         SECTION 109.  Successors and Assigns.
                       ----------------------

         All covenants and agreements in this Indenture by the Company shall
bind its successors and assigns, whether so expressed or not.

         SECTION 110.  Separability Clause.
                       -------------------

         In case any provision in this Indenture or in any Security shall be
invalid, illegal or unenforceable, the validity, legality and enforceability of
the remaining provisions shall not in any way be affected or impaired thereby,
it being intended that all of the provisions hereof shall be enforceable to the
full extent permitted by law.

         SECTION 111.  Benefits of Indenture.
                       ---------------------

         Nothing in this Indenture or in the Securities, express or implied,
shall give to any Person other than the parties hereto and their successors
hereunder and the Holders of Securities, any benefit or any legal or equitable
right, remedy or claim under this Indenture. This Indenture may not be used to
interpret another indenture, loan agreement or debt agreement of the Company or
any of its Subsidiaries. No such other indenture or loan or debt agreement may
be utilized to interpret this Indenture.

         SECTION 112.  Governing Law.
                       -------------

         THIS INDENTURE AND THE SECURITIES SHALL BE GOVERNED 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, BUT OTHERWISE WITHOUT REGARD TO PRINCIPLES
OF CONFLICT OF LAWS. THE COMPANY HEREBY IRREVOCABLY SUBMITS TO THE JURISDICTION
OF ANY NEW YORK STATE COURT SITTING IN THE BOROUGH OF MANHATTAN IN THE CITY OF
NEW YORK OR ANY FEDERAL COURT SITTING IN THE BOROUGH OF MANHATTAN IN THE CITY OF
NEW YORK IN RESPECT OF ANY SUIT, ACTION OR PROCEEDING ARISING OUT OF OR RELATING
TO THIS INDENTURE AND THE SECURITIES, AND IRREVOCABLY ACCEPTS FOR ITSELF AND IN
RESPECT OF ITS PROPERTY, GENERALLY AND UNCONDITIONALLY, JURISDICTION OF THE
AFORESAID COURTS. THE COMPANY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT THAT IT
MAY EFFECTIVELY DO SO UNDER APPLICABLE LAW, TRIAL BY JURY AND ANY OBJECTION THAT
IT MAY NOW OR HEREAFTER HAVE TO THE LAYING OF THE VENUE OF ANY SUCH SUIT, ACTION
OR PROCEEDING BROUGHT IN ANY SUCH COURT AND ANY CLAIM THAT ANY SUCH SUIT, ACTION
OR PROCEEDING BROUGHT IN ANY SUCH COURT HAS BEEN BROUGHT IN AN INCONVENIENT
FORUM. NOTHING HEREIN SHALL AFFECT THE RIGHT OF THE TRUSTEE OR ANY HOLDER OF THE
SECURITIES TO SERVE PROCESS IN ANY OTHER MANNER PERMITTED BY LAW OR TO COMMENCE
LEGAL PROCEEDINGS OR OTHERWISE PROCEED AGAINST THE COMPANY IN ANY OTHER
JURISDICTION.

         SECTION 113.  Legal Holidays.
                       --------------

         If any Interest Payment Date, Redemption Date, Purchase Date or Stated
Maturity of any Security shall not be a Business Day, then (notwithstanding any
other provision of this Indenture or of any Security other than a provision in
the Securities of any series which specifically states that such provision shall
apply in lieu of this Section) payment of interest or principal (and premium, if
any) need not be made on such date but may be made on the next succeeding
Business Day with the same force and effect (including with respect to the
accrual of interest) as if





                                       40
<PAGE>



made on the Interest Payment Date, Redemption Date, Purchase Date or at the
Stated Maturity.

         SECTION 114.  No Recourse Against Others.
                       --------------------------

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

         SECTION 115.  Duplicate Originals.
                       -------------------

         All parties may sign any number of copies or counterparts of this
Indenture. Each signed copy or counterpart shall be an original, but all of them
together shall represent the same agreement.

                                   ARTICLE TWO

                                  SECURITY FORM

         SECTION 201.  Global and Certificated Securities.
                       ----------------------------------

         The Securities of each series shall be substantially in the form as set
forth in Exhibit A hereto or as shall be established in one or more indentures
supplemental hereto or approved from time to time by or pursuant to a Board
Resolution in accordance with Section 301. The Securities may have such
appropriate insertions, omissions, substitutions and other variations as are
required or permitted by this Indenture or any indenture supplemental hereto,
and may have notations, legends or endorsements required by law, stock exchange
rule, agreements to which the Company is subject, if any, or usage (provided
that any such notation, legend or endorsement is in a form acceptable to the
Company). Each Security shall be dated the date of its authentication.

         (a) Global Securities. Securities of or within a series may be issued
in the form of one or more permanent global securities in definitive, fully
registered form with the global security legend set forth in Section 307 (each,
a "Global Security"), which shall be deposited on behalf of the purchasers of
such Securities represented thereby with the Trustee, at its New York office, as
custodian for the Depositary (or with such other custodian as the Depositary may
direct), and registered in the name of the Depositary or a nominee of the
Depositary, duly






                                       41
<PAGE>



executed by the Company and authenticated by the Trustee as hereinafter
provided. The aggregate principal amount of the Global Security may from time to
time be increased or decreased by adjustments made on the records of the Trustee
and the Depositary or its nominee as hereinafter provided.

         The Depositary Trust Company shall act as initial Depositary. If at any
time the Depositary for the Securities of a series represented by one or more
Global Securities notifies the Company that it is unwilling or unable to
continue as Depositary of such Securities or if at any time the Depositary shall
no longer be eligible as provided in the second sentence of the definition of
"Depositary" and a successor Depositary is not appointed by the Company within
90 days after the Company receives such notice or becomes aware of such
condition, the Company shall promptly execute, and the Trustee shall promptly
authenticate and deliver, Securities in Certificated form, in authorized
denominations, and in an aggregate principal amount equal to the principal
amount of the Global Security or Securities then outstanding in exchange for
such Global Security or Securities, and this Section 201(a) and Section 201(b)
shall no longer be applicable to the Securities. In addition, the Company may at
any time and in its sole discretion determine that the Securities of any series
shall no longer be represented by Global Securities. In such event the Company
shall promptly execute, and the Trustee, upon receipt of a Company Order
evidencing such determination by the Company, shall promptly authenticate and
deliver, Securities of such series in Certificated form without coupons, in
authorized denominations and in an aggregate principal amount equal to the
principal amount of the Global Security or Securities then outstanding in
exchange for such Global Security or Securities and this Section 201(a) and
Section 201(b) shall no longer be applicable to the Securities. Upon the
exchange of the Global Securities for such Securities in Certificated form, in
authorized denominations, such Global Securities shall be cancelled by the
Trustee. Such Securities in Certificated form issued in exchange for the Global
Securities pursuant to this Section 201(a) and Section 201(b) shall be
registered in such names and in such authorized denominations as the Depositary,
pursuant to instructions from its direct or indirect participants or otherwise,
shall instruct the Trustee. The Trustee shall deliver such Securities to the
Persons in whose names such Securities are so registered.

         Notwithstanding any other provision hereof to the contrary, so long as
the outstanding Securities of any series are represented by one or more Global
Securities, the Company shall pay or cause to be paid the principal of, and
interest on, such Global Securities to the Depositary or its nominee by wire
transfer of immediately available funds on the date such payments




                                       42
<PAGE>



are due in accordance with the operational arrangements of the Depositary, as
such arrangements are amended from time to time.

         (b) Book-Entry Provisions. This Section 201(b) shall apply only to the
Global Security or Securities deposited with or on behalf of the Depositary.

         The Company shall execute and the Trustee shall, in accordance with
this Section 201(b), authenticate and deliver initially one or more Global
Securities that (a) shall be registered in the name of the Depositary for such
Global Security or Securities or the nominee of such Depositary and (b) shall be
delivered by the Trustee to such Depositary or pursuant to such Depositary's
instructions or held by the Trustee as custodian for the Depositary.

         Members of, or participants in, the Depositary ("Agent Members") shall
have no rights under this Indenture with respect to the Global Security or
Securities held on their behalf by the Depositary or by the Trustee as the
custodian of the Depositary or under such Global Security, and the Depositary
may be treated by the Company, the Trustee and any agent of the Company or the
Trustee as the absolute owner of such Global Security or Securities for all
purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent
the Company, the Trustee or any agent of the Company or the Trustee from giving
effect to any written certification, proxy or other authorization furnished by
the Depositary or impair, as between the Depositary and its Agent Members, the
operation of customary practices of such Depositary governing the exercise of

Securities.

Section 307 or Section 309, owners of beneficial interests in the Global

    on the Regular Record Date for such interest, and the extent to which, or

         (18) if the Securities of the series are to be issued upon the exercise
    of warrants, the time, manner and place for such Securities to be
    authenticated and delivered;

         (19) the obligation, if any, of the Company to permit the conversion of
    the Securities of such series into the Company's Common Stock or Preferred
    Stock, and the terms and conditions upon which such conversion shall be

    rate, the conversion period, any adjustment of the applicable conversion
    price, any requirements relative to reservation of shares for purposes of

         (20) any other terms of the series (which terms shall not be
    inconsistent with the provisions of this Indenture).

         All Securities of any one series shall be substantially identical
except as to denomination and except as may otherwise be provided in or pursuant
to any such Board Resolution (subject to Section 303) and set forth in such
Officers' Certificate or in any such indenture supplemental hereto. All
Securities of any one series need not be issued at the same time and, unless
otherwise provided, a series may be reopened, without the consent of the
Holders, for issuances of additional Securities of such series.

         If any of the terms of the Securities of any series are established by
action taken pursuant to one or more Board Resolutions, a copy of an appropriate
record of such action(s) shall be certified by the Secretary or an Assistant
Secretary of the Company and delivered to the Trustee at or prior to the
delivery of the Officers' Certificate setting forth the terms of the Securities
of such series.

         SECTION 302. Denominations. The Securities of each series shall be
issuable in such denominations as shall be specified as contemplated by Section
301. In the absence of any such provisions with respect to the Securities of any
series, the Securities of such series, other than Securities issued in global
form (which may be of any denomination), shall be issuable in denominations of
$1,000 and any integral multiple thereof.

         SECTION 303. Execution and Authentication.
                      ----------------------------

         The Securities shall be executed on behalf of the Company by its
Chairman of the Board, its President or one of its Vice Presidents, attested by
its Secretary or one of its




                                       47
<PAGE>



Assistant Secretaries. The signature of any of these officers on the Securities
may be manual or facsimile.

         Securities bearing the manual or facsimile signatures of individuals
who were at any time the proper officers of the Company shall bind the Company,
notwithstanding that such individuals or any of them have ceased to hold such
offices prior to the authentication and delivery of such Securities or did not
hold such offices at the date of such Securities.

         At any time and from time to time after the execution and delivery of
this Indenture, the Company may deliver Securities of any series executed by the
Company to the Trustee for authentication, together with a Company Order for the
authentication and delivery of such Securities; and the Trustee in accordance
with such Company Order shall authenticate and deliver such Securities as in
this Indenture provided and not otherwise.

         If all the Securities of any series are not to be issued at one time
and if the Board Resolution or supplemental indenture establishing such series
shall so permit, such Company Order may set forth procedures acceptable to the
Trustee for the issuance of such Securities and determining the terms of
particular Securities of such series, such as interest rate or formula, maturity
date, date of issuance and date from which interest shall accrue. In
authenticating such Securities, and accepting the additional responsibilities
under this Indenture in relation to such Securities, the Trustee shall be
entitled to receive, and (subject to Trust Indenture Act Section 315(a) through
315(d)) shall be fully protected in relying upon,

     (i)  an Opinion of Counsel stating that

         (a) the form or forms of such Securities have been established in
    conformity with the provisions of this Indenture;

         (b) the terms of such Securities have been established in conformity
    with the provisions of this Indenture; and

         (c) such Securities, when completed by appropriate insertions and
    executed and delivered by the Company to the Trustee for authentication in
    accordance with this Indenture, authenticated and delivered by the Trustee
    in accordance with this Indenture and issued by the Company in the manner
    and subject to any conditions specified in such Opinion of Counsel, will
    constitute legal, valid and binding obligations of the Company, enforceable
    in accordance with their terms, subject to applicable bankruptcy,
    insolvency,



                                       48
<PAGE>



    reorganization and other similar laws of general applicability relating to
    or affecting the enforcement of creditors' rights, to general equitable
    principles and to such other qualifications as such counsel shall conclude
    do not materially affect the rights of Holders of such Securities; and

    (ii) an Officers' Certificate stating that all conditions precedent provided
for in this Indenture relating to the issuance of the Securities have been
complied with and that, to the best of the knowledge of the signers of such
certificate, that no Event of Default with respect to any of the Securities
shall have occurred and be continuing.

         If such form or terms have been so established, the Trustee shall not
be required to authenticate such Securities if the issue of such Securities
pursuant to this Indenture will affect the Trustee's own rights, duties,
obligations or immunities under the Securities and this Indenture or otherwise
in a manner which is not reasonably acceptable to the Trustee.

         Notwithstanding the provisions of Section 301 and of the preceding
paragraph, if all the Securities of any series are not to be issued at one time,
it shall not be necessary to deliver an Officers' Certificate otherwise required
pursuant to Section 301 or a Company Order, or an Opinion of Counsel or an
Officers' Certificate otherwise required pursuant to the preceding paragraph at
the time of issuance of each Security of such series, but such order, opinion
and certificates, with appropriate modifications to cover such future issuances,
shall be delivered at or before the time of issuance of the first Security of
such series.

         Each Security shall be dated the date of its authentication.

         No Security shall be entitled to any benefit under this Indenture or be
valid or obligatory for any purpose unless there appears on such Security a
certificate of authentication substantially in the form provided for herein
executed by the Trustee by manual signature, and such certificate upon any
Security shall be conclusive evidence, and the only evidence, that such Security
has been duly authenticated and delivered hereunder.

         SECTION 304. Registrar and Paying Agent.
                      --------------------------

         The Company shall maintain an office or agency where each series of
Securities may be presented for registration of transfer or for exchange (the
"Security Registrar") and an office





                                       49
<PAGE>



or agency where each series of Securities may be presented for payment (the
"Paying Agent"). The Security Registrar shall keep a register (the "Security
Register") for each series of Securities and of their transfer and exchange. The
Company may have one or more co-registrars and one or more additional paying
agents. The term "Paying Agent" includes any additional paying agent.

         The Company shall enter into an appropriate agency agreement with any
Security Registrar, Paying Agent or co-registrar not a party to this Indenture,
which shall incorporate the terms of the Trust Indenture Act. The agreement
shall implement the provisions of this Indenture that relate to such agent. The
Company shall notify the Trustee of the name and address of any such agent. If
the Company fails to maintain a Security Registrar or Paying Agent, the Trustee
shall act as such and shall be entitled to appropriate compensation therefor
pursuant to Section 607. The Company or any of its U.S. wholly owned
Subsidiaries may act as Paying Agent, Security Registrar, co-registrar or
transfer agent.

         The Company initially appoints the Trustee as Security Registrar and
Paying Agent in connection with each series of Securities.

         SECTION 305. Paying Agent To Hold Money in Trust.

         At least one Business Day prior to each due date of the principal and
interest on any Security, the Company shall deposit with the Paying Agent a sum
sufficient to pay such principal and interest when so becoming due. The Company
shall require each Paying Agent (other than the Trustee) to agree in writing
that the Paying Agent shall hold in trust for the benefit of Holders or the
Trustee all money held by the Paying Agent for the payment of principal of or
interest on the Securities and shall notify the Trustee of any default by the
Company in making any such payment. If the Company or one of its U.S. wholly
owned Subsidiaries acts as Paying Agent, it shall segregate the money held by it
as Paying Agent and hold it as a separate trust fund. The Company at any time
may require a Paying Agent (other than the Trustee) to pay all money held by it
to the Trustee and to account for any funds disbursed by the Paying Agent. Upon
complying with this Section, the Paying Agent shall have no further liability
for the money delivered to the Trustee.

         SECTION 306. Holder Lists.
                      ------------

         The Trustee shall preserve in as current a form as is reasonably
practicable the most recent list available to it of the names and addresses of
Holders. If the Trustee is not the





                                       50
<PAGE>


Security Registrar, the Company shall furnish to the Trustee, in writing at
least five Business Days before each interest payment date and at such other
times as the Trustee may request in writing, a list in such form and as of such
date as the Trustee may reasonably require of the names and addresses of
Holders.

         SECTION 307. Transfer and Exchange of Global Securities.
                      ------------------------------------------

         (a) Transfer and Exchange of Global Securities. (i) The transfer and
exchange of the Global Security or Securities of any series or beneficial
interests therein shall be effected through the Depositary, in accordance with
this Indenture (including applicable restrictions on transfer set forth herein,
if any) and the procedures of the Depositary therefor, if applicable.

              (ii) Notwithstanding any other provisions of this Indenture (other
    than the provisions set forth in Section 307), the Global Security of any
    series may not be transferred as a whole except by the Depositary to a
    nominee of the Depositary or by a nominee of the Depositary to the
    Depositary or another nominee of the Depositary or by the Depositary or any
    such nominee to a successor Depositary or a nominee of such successor
    Depositary.

         (b) Cancellation or Adjustment of Global Securities. At such time as
all beneficial interests in the Global Securities of any series have either been
exchanged for Certificated Securities of the same series, redeemed, repurchased
or cancelled, such Global Securities of such series shall be returned to the
Trustee for cancellation or retained and cancelled by the Trustee. At any time
prior to such cancellation, if any beneficial interests in the Global Securities
of any series are exchanged for Certificated Securities of the same series,
redeemed, repurchased or cancelled, the principal amount of Securities
represented by such Global Securities of such series shall be reduced and an
adjustment shall be made by the Trustee or the custodian to reflect such
reduction on the books and records of the custodian for such Global Securities
of such series with respect to such Global Securities of such series.

         (c) Obligations with Respect to Transfers and Exchanges of Securities.
             -----------------------------------------------------------------

              (i) To permit registrations of transfers and exchanges, the
    Company shall execute and the Trustee shall authenticate within a reasonable
    time Certificated Securities, and Global Securities at the Security




                                       51
<PAGE>


    Registrar's or co-registrar's written request accompanied by an equal
    principal amount of Securities to be cancelled and, if the Security
    Registrar is not the Trustee, the Security Registrar shall provide to the
    Trustee an opinion of counsel acceptable to the Trustee and the Company to
    the effect that the Security Registrar has received all of the instruments
    and documents required by this Section 307 for such transfer or exchange.

              (ii) No service charge shall be made for any 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.

              (iii) Prior to the due presentation for registration of transfer
    of any Security, the Company, the Trustee, the Paying Agent, the Security
    Registrar or any co-registrar may deem and treat the person in whose name a
    Security is registered as the absolute owner of such Security for the
    purpose of receiving payment of principal of and interest on such Security
    and for all other purposes whatsoever, whether or not such Security is
    overdue, and none of the Company, the Trustee, the Paying Agent, the
    Security Registrar or any co-registrar shall be affected by notice to the
    contrary.

              (iv) All Securities issued upon any transfer or exchange pursuant
    to the terms of this Indenture shall evidence the same debt and shall be
    entitled to the same benefits under this Indenture as the Securities
    surrendered upon such transfer or exchange.

         (d) No Obligation of the Trustee.
             ----------------------------

              (i) The Trustee (whether in its capacity as trustee, Security
    Registrar or Paying Agent) shall have no responsibility or obligation to any
    beneficial owner of any Global Security, a member of, or a participant in
    the Depositary or other Person with respect to the accuracy of the records
    of the Depositary or its nominee or of any participant or member thereof,
    with respect to any ownership interest in the Securities of any series or
    with respect to the delivery to any participant, member, beneficial owner or
    other Person (other than the Depositary) of any notice (including any notice
    of redemption) or the payment of any amount, under or with respect to such
    Securities. All notices and communications to be given to the Holders and
    all payments to be made to Holders under the Securities shall be given or
    made only to or upon the order of the registered Holders (which shall be the
    Depositary or its




                                       52
<PAGE>


    nominee in the case of a Global Security). The rights of beneficial owners
    in the Global Securities shall be exercised only through the Depositary
    subject to the applicable rules and procedures of the Depositary. The
    Trustee (whether in its capacity as trustee, Security Registrar or Paying
    Agent) may rely and shall be fully protected in relying upon information
    furnished by the Depositary with respect to its members, participants and
    any beneficial owners.

              (ii) The Trustee (whether in its capacity as trustee, Security
    Registrar or Paying Agent) shall have no obligation or duty to monitor,
    determine or inquire as to compliance with any restrictions on transfer
    imposed under this Indenture or under applicable law, regulations or
    exchange rules with respect to any transfer of any interest in any Security
    (including any transfers between or among Depositary participants, members
    or beneficial owners in the Global Securities), other than to require
    delivery of such certificates and other documentation or evidence as are
    expressly required by, and to do so if and when expressly required by, the
    terms of this Indenture, and to examine the same to determine substantial
    compliance as to form with the express requirements hereof.

         (e) Each Global Security will also bear the following legend:

              "This Security is issued in global form and registered in the name
    of the Depositary or a nominee thereof. Unless and until it is exchanged in
    whole or in part for Securities in definitive form in accordance with the
    terms hereof and of the Indenture referred to on the reverse hereof, this
    Security may not be transferred except as a whole by the Depositary to a
    nominee of the Depositary, or by a nominee of the Depositary to the
    Depositary or another nominee of the Depositary, or by the Depositary or any
    such nominee to a successor Depositary or a nominee of such successor
    Depositary. Unless this certificate is presented by an authorized
    representative of the Depositary to the Company or its agent for
    registration of transfer, exchange or payment, and any certificate issued is
    registered in the name of the Depositary or its nominee and any payment is
    made to the Depositary or its nominee, ANY TRANSFER, PLEDGE OR OTHER USE
    HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL since the
    registered owner hereof has an interest herein."

         (f) CUSIP Numbers. The Company in issuing Securities may use "CUSIP"
numbers (if then generally in use), and, if so,





                                       53
<PAGE>



the Trustee shall use CUSIP numbers in notices of redemption or repurchase as a
convenience to Holders; provided that any such notice may state that no
representation is made as to the correctness of such numbers either as printed
on the Securities or as contained in any notice of a redemption or repurchase
and that reliance may be placed only on the other identification numbers printed
on the Securities, and any such redemption or repurchase shall not be affected
by any defect in or omission of such numbers.

         SECTION 308. Mutilated, Destroyed, Lost and Stolen Securities.
                      ------------------------------------------------

         If any mutilated Security is surrendered to the Trustee, the Company
shall execute and the Trustee shall authenticate and deliver in exchange
therefor a new Security of like tenor and principal amount and bearing a number
not contemporaneously outstanding.

         If there shall be delivered to the Company and the Trustee (i) evidence
to their satisfaction of the destruction, loss or theft of any Security and (ii)
such security or indemnity as may be required by them to save each of them and
any agent of either of them harmless, then, in the absence of notice to the
Company or the Trustee that such Security has been acquired by a bona fide
purchaser, the Company shall execute and upon its request the Trustee shall
authenticate and deliver, in lieu of any such destroyed, lost or stolen
Security, a new Security of the same series and of like tenor and principal
amount and bearing a number not contemporaneously outstanding.

         In case any such mutilated, destroyed, lost or stolen Security
has become or is about to become due and payable, the Company in its discretion
may, instead of issuing a new Security, pay such Security.

         Upon the issuance of any new Security under this Section, the
Company may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto and any other
expenses (including the fees and expenses of the Trustee) connected therewith.

         Every new Security of any series issued pursuant to this Section 308 in
lieu of any destroyed, lost or stolen Security shall constitute an original
additional contractual obligation of the Company, whether or not the destroyed,

or payment of mutilated, destroyed, lost or stolen Securities.

         SECTION 309. Temporary Securities and Certificated Securities.
                      ------------------------------------------------

         (a) Until Certificated Securities for any series are ready for
delivery, the Company may prepare and the Trustee shall authenticate temporary
Securities. Temporary Securities shall be substantially in the form of
Certificated Securities but may have variations that the Company considers
appropriate for temporary Securities. Without unreasonable delay, the Company
shall prepare and the Trustee shall authenticate Certificated Securities of such
series and deliver them in exchange for temporary Securities of such series.

         (b) The Global Security or Securities of any series deposited with the
Depositary or with the Trustee as custodian for the Depositary pursuant to
Section 201 shall be transferred to the beneficial owners thereof in the form of
Certificated Securities of the same series in an aggregate principal amount
equal to the principal amount of such Global Security, in exchange for such
Global Securities, only if such transfer complies with Section 307 and (i) the
Depositary notifies the Company that it is unwilling or unable to continue as
Depositary for such Global Security or if at any time such Depositary ceases to
be a "clearing agency" registered under the Exchange Act and a successor
depositary is not appointed by the Company within 90 days of such notice, (ii) a
Default has occurred and is continuing or (iii) the Company, in its sole
discretion, notifies the Trustee in writing that it elects to cause the issuance
of Certificated Securities under this Indenture.

         (c) Any Global Security that is transferable to the beneficial owners
thereof pursuant to this Section shall be surrendered by the Depositary to the
Trustee located in the Borough of Manhattan, The City of New York, to be so
transferred, in whole or from time to time in part, without charge, and the
Trustee shall authenticate and deliver, upon such transfer of each portion of
such Global Securities, an equal aggregate principal amount of Securities of the
same series of authorized denominations. Any portion of the Global Securities
transferred pursuant to this Section shall be executed, authenticated and
delivered only in denominations of $1,000 and any integral multiple thereof and
registered in such names as the Depositary shall direct.

         (d) Subject to the provisions of Section 309(c), the registered Holder
of the Global Security may grant proxies and otherwise authorize any Person,
including agent members, participants and Persons that may hold interests
through agent members, to take any action which a Holder is entitled to take
under this Indenture or the Securities.

         (e) In the event of the occurrence of any of the events specified in
Section 309(b), the Company will promptly make available to the Trustee a
reasonable supply of Certificated Securities in fully registered form.

         SECTION 310. Payment of Interest; Interest Rights Preserved.
                      ----------------------------------------------

         Interest on any Security that is payable and is punctually paid or duly
provided for on any Interest Payment Date shall be paid to the Person in whose
name that Security (or one or more Predecessor Securities) is registered at the
close of business on the Regular Record Date for such interest.

         Any interest on any Security of any series that is payable but is not
punctually paid or duly provided for on any Interest Payment Date (herein called
"Defaulted Interest") shall forthwith cease to be payable to the Holder on the
relevant Regular Record Date by virtue of having been such Holder, and such
Defaulted Interest may be paid by the Company, at its election in each case, as
provided in clause (1) or (2) below:

         (1) The Company may elect to make payment of any Defaulted Interest to
    the Persons in whose names the Securities of such series (or their
    respective Predecessor Securities) are registered at the close of business
    on a Special Record Date for the payment of such Defaulted Interest, which
    shall be fixed in the following manner. The Company shall notify the Trustee
    in writing of the amount of Defaulted Interest proposed to be paid on each
    Security of such series and the date of the proposed payment and at the same
    time the Company shall deposit with the Trustee an amount of money equal to
    the aggregate amount proposed to be paid in respect of such Defaulted
    Interest or shall make arrangements satisfactory to the Trustee for such
    deposit prior to the date of the proposed payment, such money when deposited
    to be held in trust for the benefit of the Persons entitled to such
    Defaulted Interest as provided in this clause. Thereupon the Trustee shall
    fix a Special Record Date for the payment of such Defaulted Interest that
    shall be not more than 15 days and not less than 10 days prior to the date
    of the proposed payment and not less than 10 days after the receipt by the
    Trustee of the notice of the



                                       56
<PAGE>



    proposed payment. The Trustee shall promptly notify the Company of such
    Special Record Date and, in the name and at the expense of the Company,
    shall cause notice of the proposed payment of such Defaulted Interest and
    the Special Record Date therefor to be given to each Holder of Securities of
    such series in the manner specified in Section 106 not less than 10 days
    prior to such Special Record Date. Notice of the proposed payment of such
    Defaulted Interest and the Special Record Date therefor having been so
    given, such Defaulted Interest shall be paid to the Persons in whose names
    the Securities of such series (or their respective Predecessor Securities)
    are registered at the close of business on such Special Record Date and
    shall no longer be payable pursuant to the following clause (2).

         (2) The Company may make payment of any Defaulted Interest on
    Securities of any series in any other lawful manner not inconsistent with
    the requirements of any securities exchange on which the Securities may be
    listed, and upon such notice as may be required by such exchange, if, after
    notice given by the Company to the Trustee of the proposed payment pursuant
    to this clause, such manner of payment shall be deemed practicable by the
    Trustee.

         Subject to the foregoing provisions of this Section, each Security
delivered under this Indenture upon registration of transfer of or in exchange
for or in lieu of any other Security shall carry the rights to interest accrued
and unpaid, and to accrue, which were carried by such other Security.

         SECTION 311. Persons Deemed Owners.
                      ---------------------

         Prior to due presentment of a 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 such Security is registered as the owner of such
Security for the purpose of receiving payment of principal of (and premium, if
any) and (subject to Section 310) interest on such Security and for all other
purposes whatsoever, whether or not such Security be overdue, and neither the
Company, the Trustee nor any agent of the Company or the Trustee shall be
affected by notice to the contrary.

         SECTION 312. Cancellation.
                      ------------

         All Securities surrendered for payment, redemption, registration of
transfer or exchange or for credit against any Offer to Purchase pursuant to
Section 1013 or 1015 shall, if surrendered to any Person other than the Trustee,
be delivered to the Trustee and shall be promptly cancelled by it. The Company





                                       57
<PAGE>



may at any time deliver to the Trustee for cancellation any Securities
previously authenticated and delivered hereunder that the Company may have
acquired in any manner whatsoever, and all Securities so delivered shall be
promptly cancelled by the Trustee. No Securities shall be authenticated in lieu
of or in exchange for any Securities cancelled as provided in this Section 312,
except as expressly permitted by this Indenture. All cancelled Securities held
by the Trustee shall be disposed of as directed by a Company Order; provided
that the Trustee shall not be required to destroy cancelled Securities.

         SECTION 313. Computation of Interest.
                      -----------------------

         Interest on the Securities of any series shall be computed on the basis
of a 360-day year of twelve 30-day months.

series of Securities specified by the Company and the Trustee, on demand of and
at the expense of the Company, shall execute proper instruments acknowledging

         SECTION 502. Acceleration of Maturity; Rescission and Annulment.

         If an Event of Default with respect to  Securities of any series at the
time outstanding  (other than an Event of Default specified in Section 501(7) or
(8))  occurs and is  continuing,  then and in every such case the Trustee or the
Holders of not less than 25 percent in  principal  amount at Stated  Maturity of
the Outstanding Securities of that series may declare


                                       61
<PAGE>


the Default  Amount of all the  Outstanding  Securities of that series to be due
and  payable  immediately  by a notice in  writing  to the  Company  (and to the
Trustee if given by Holders),  and upon any such declaration such Default Amount
shall become  immediately due and payable.  If an Event of Default  specified in
Section  501(7) or (8) occurs,  the  Default  Amount of the  Securities  of that
series then  Outstanding  shall ipso facto  become  immediately  due and payable
without any declaration or other Act on the part of the Trustee or any Holder.

         At any time after such a declaration  of  acceleration  with respect to
Securities  of any  series  has been made and  before a  judgment  or decree for
payment of the money due has been obtained by the Trustee as hereinafter in this
Article  Five  provided,  the Holders of a majority in  principal  amount of the
Outstanding  Securities of that series, by written notice to the Company and the
Trustee, may rescind and annul such declaration and its consequences if

         (1) the Company has paid or deposited with the Trustee a sum sufficient
    to pay

              (A) all overdue interest on all Securities of that series (without
         duplication of any amount thereof paid or deposited  pursuant to clause
         (B) or (C) below),

              (B) the Default Amount of (and premium, if any, on) any Securities
         of that series that have become due otherwise than by such  declaration
         of  acceleration  (including any securities of such series  required to
         have  been  purchased  on any  Purchase  Date  pursuant  to an Offer to
         Purchase  made by the Company)  and, to the extent that payment of such
         interest  is  lawful,  interest  thereon  at the rate  provided  by the
         Securities of such series  (without  duplication  of any amount thereof
         paid or deposited pursuant to clause (A) above or clause (C) below),

              (C) to the  extent  that  payment  of  such  interest  is  lawful,
         interest upon overdue  interest at the rate provided by the  Securities
         of such  series  (without  duplication  of any amount  thereof  paid or
         deposited pursuant to clause (A) or (B) above), and

              (D) all sums paid or  advanced by the  Trustee  hereunder  and the
         reasonable  compensation,  expenses,  disbursements and advances of the
         Trustee, its agents and counsel; and


                                       62
<PAGE>


         (2) all Events of Default  with  respect to  Securities  of that series
    have been cured or waived as provided in Section 513.

No such  rescission  shall  affect  any  subsequent  default or impair any right
consequent thereon.

         SECTION 503.  Collection of  Indebtedness  and Suits for Enforcement by
Trustee. The Company covenants that if:

         (1) default is made in the payment of any  interest on any  Security of
    any series when such  interest  becomes  due and  payable  and such  default
    continues for a period of 30 days, or

         (2) default is made in the payment of the principal of (or premium,  if
    any, on) any Security of any series at the final Stated Maturity thereof or,
    with respect to any Security required to have been purchased  pursuant to an
    Offer to Purchase made by the Company, at the Purchase Date thereof,

the Company shall, upon demand of the Trustee, pay to it, for the benefit of the
Holders of such Securities of such series, the whole amount then due and payable
on such Securities' principal, premium, if any, and interest, and, to the extent
that  payment of such  interest  shall be legally  enforceable,  interest on any
overdue principal,  premium, if any, and overdue interest,  at the rate provided
by the  Securities,  and, in addition  thereto,  such further amount as shall be
sufficient  to cover  the  costs  and  expenses  of  collection,  including  the
reasonable  compensation,  expenses,  disbursements and advances of the Trustee,
its agents and counsel.

         If the Company  fails to pay such amounts  forthwith  upon such demand,
the Trustee, in its own name and as trustee of an express trust, may institute a
judicial  proceeding  for the  collection  of the  sums so due and  unpaid,  may
prosecute  such  proceeding to judgment or final decree and may enforce the same
against the Company or any other obligor upon the  Securities of such series and
collect the moneys  adjudged or decreed to be payable in the manner  provided by
law out of the Property of the Company or any other obligor upon the  Securities
of such series, wherever situated.

         If an Event of Default with respect to  Securities of any series occurs
and is  continuing,  the  Trustee may in its  discretion  proceed to protect and
enforce its rights and the rights of the Holders of Securities of such series by
such appropriate  judicial  proceedings as the Trustee shall deem most


                                       63
<PAGE>


effectual  to protect  and  enforce any such  rights,  whether for the  specific
enforcement  of any  covenant or  agreement  in this  Indenture or in aid of the
exercise of any power granted herein, or to enforce any other proper remedy.

         SECTION 504.  Trustee May File Proofs of Claim. In case of any judicial
proceeding  relative to the Company (or any other obligor upon the  Securities),
its Property or assets or its creditors,  the Trustee  (irrespective  of whether
the principal of, (premium,  if any) or interest on the Securities of any series
then  shall  be due and  payable  as  therein  expressed  or by  declaration  or
otherwise  and  irrespective  of whether  the Trustee has made any demand on the
Company  for the  payment of overdue  principal,  (premium,  if any) or interest
shall  be  entitled  and  empowered,  by  intervention  in  such  proceeding  or
otherwise,  to file such proofs of claim and other  papers or  documents  and to
take any and all actions  authorized  under the Trust  Indenture Act in order to
have  claims of the  Holders of the  Securities  of such  series and the Trustee
(including any claim for reasonable  compensation,  expenses,  disbursements and
advances of the Trustee,  its agents or counsel) allowed in any such proceeding.
In particular, the Trustee shall be authorized to collect and receive any moneys
or other  property  payable or  deliverable on any such claims and to distribute
the  same;  and  any  custodian,   receiver,   assignee,  trustee,   liquidator,
sequestrator or other similar official in any such judicial proceeding is hereby
authorized by each Holder of the Securities of such series to make such payments
to the Trustee and, in the event that the Trustee shall consent to the making of
such payments  directly to the Holders,  to pay to the Trustee any amount due it
for the reasonable  compensation,  expenses,  disbursements  and advances of the
Trustee,  its agents and counsel,  and any other  amounts due the Trustee  under
Section  607. To the extent  that  payment of any such  compensation,  expenses,
disbursements  and  advances of the  Trustee,  its agents and  counsel,  and any
amounts due the Trustee  under  Section 607 hereof out of the estate in any such
proceeding shall be denied for any reason,  payment of the same shall be secured
by a Lien and shall be paid out of any and all distributions,  dividends, money,
securities  and other  properties  that the  Holders of the  Securities  of such
series may be entitled to receive in such proceedings, whether in liquidation or
under any plan of reorganization or arrangement or otherwise.

         No provision of this Indenture shall be deemed to authorize the Trustee
to  authorize  or consent to or accept or adopt on behalf of any Holder any plan
of  reorganization,   arrangement,   adjustment  or  composition  affecting  the
Securities of any series or the rights of any Holder thereof or to authorize the
Trustee to vote in  respect  of the claim of any Holder in any such  proceeding;
provided  that the Trustee may, on behalf of the 


                                       64
<PAGE>


Holders,  vote for the election of a trustee in bankruptcy  or similar  official
and be a member of a creditors or other similar committee.

         SECTION  505.   Trustee  May  Enforce  Claims  Without   Possession  of
Securities.  All  rights  of action  and  claims  under  this  Indenture  or the
Securities may be prosecuted and enforced by the Trustee  without the possession
of any of the  Securities or the production  thereof in any proceeding  relating
thereto,  and any such proceeding  instituted by the Trustee shall be brought in
its own name as trustee of an express trust, and any recovery of judgment shall,
after  provision  for the  payment  of the  reasonable  compensation,  expenses,
disbursements  and advances of the Trustee,  its agents and counsel,  be for the
ratable  benefit  of the  Holders  of the  Securities  in  respect of which such
judgment has been recovered.

         SECTION 506. Application of Money Collected. Any money collected by the
Trustee  pursuant to this Article Five shall be applied in the following  order,
at the date or dates fixed by the Trustee  and, in case of the  distribution  of
such  money on account of  principal  (or  premium,  if any) or  interest,  upon
presentation  of the Securities and the notation  thereon of the payment if only
partially paid and upon surrender thereof if fully paid:

         FIRST: To the payment of all amounts due the Trustee under Section 607;
    and

         SECOND:  To the  payment  of the  amounts  then due and  unpaid  on the
    Securities  in respect  of which or for the  benefit of which such money has
    been  collected,  ratably,  without  preference  or  priority  of any  kind,
    according  to the amounts due and payable on such  Securities  in respect of
    principal (and premium, if any) and interest; and

         THIRD: To whosoever may be lawfully entitled thereto, the remainder, if
    any.

         SECTION  507.  Limitation  on Suits.  No Holder of any  Security of any
series shall have any right to institute any proceeding,  judicial or otherwise,
with respect to this Indenture, or for the appointment of a receiver or trustee,
or for any other remedy hereunder, unless

         (1) such Holder has previously given written notice to the Trustee of a
    continuing Event of Default with respect to the Securities of that series;


     
                                       65
<PAGE>
     

         (2) the Holders of not less than 25 percent in principal  amount of the
    Outstanding Securities of that series shall have made written request to the
    Trustee to institute  proceedings in respect of such Event of Default in its
    own name as Trustee hereunder;

         (3) such  Holder or  Holders  have  offered to the  Trustee  reasonable
    indemnity  against the costs,  expenses  and  liabilities  to be incurred in
    compliance with such request;

         (4) the Trustee for 60 days after its receipt of such  notice,  request
    and offer of indemnity has failed to institute any such proceeding; and

         (5) no direction  inconsistent with such written request has been given
    to the Trustee  during  such  60-day  period by the Holders of a majority in
    principal amount of the Outstanding Securities of that series;

it being  understood  and intended  that no one or more  Holders  shall have any
right in any manner  whatever by virtue of, or by availing of, any  provision of
this Indenture to affect,  disturb or prejudice the rights of any other Holders,
or to obtain or to seek to obtain  priority or preference over any other Holders
or to enforce  any right  under  this  Indenture,  except in the  manner  herein
provided and for the equal and ratable benefit of all the Holders.

         SECTION  508.  Unconditional  Right of Holders  to  Receive  Principal,
Premium and Interest. Notwithstanding any other provision in this Indenture, the
Holder  of  any   Security   shall  have  the  right,   which  is  absolute  and
unconditional,  to receive full payment of the  principal,  of (and premium,  if
any) and (subject to Section 310)  interest on such  Security on the  respective
Stated Maturities expressed in such Security (or, in the case of redemption,  on
the  Redemption  Date or in the case of an Offer to Purchase made by the Company
and accepted as to such Security,  on the Purchase Date) in accordance  with the
terms  of this  Indenture  and the  Securities  and to  institute  suit  for the
enforcement of any such payment,  and such rights shall not be impaired  without
the consent of such Holder.

         SECTION 509. Restoration of Rights and Remedies.  If the Trustee or any
Holder has  instituted  any proceeding to enforce any right or remedy under this
Indenture and such proceeding has been discontinued or abandoned for any reason,
or has been determined  adversely to the Trustee or to such Holder,  then and in
every such case,  subject to any determination in such proceeding,  the Company,
the Trustee and the Holders  shall be restored  severally  and  respectively  to
their former  positions  


                                       66
<PAGE>

hereunder and  thereafter all rights and remedies of the Trustee and the Holders
shall continue as though no such proceeding had been instituted.

         SECTION  510.  Rights  and  Remedies  Cumulative.  Except as  otherwise
provided with respect to the  replacement  or payment of  mutilated,  destroyed,
lost or stolen  Securities  in the last  paragraph  of Section  308, no right or
remedy  herein  conferred  upon or  reserved to the Trustee or to the Holders is
intended  to be  exclusive  of any other  right or remedy,  and every  right and
remedy shall,  to the extent  permitted by law, be cumulative and in addition to
every other right and remedy given hereunder or now or hereafter existing at law
or in equity or  otherwise.  The  assertion or employment of any right or remedy
hereunder or otherwise shall not prevent the concurrent  assertion or employment
of any other appropriate right or remedy.

         SECTION 511. Delay or Omission Not Waiver.  No delay or omission of the
Trustee  or of any  Holder  of any  Security  to  exercise  any  right or remedy
accruing  upon any Event of  Default  shall  impair  any such right or remedy or
constitute  a waiver of any such Event of Default  or an  acquiescence  therein.
Every right and remedy given by this Article Five or by law to the Trustee or to
the Holders may be  exercised  from time to time,  and as often as may be deemed
expedient, by the Trustee or by the Holders, as the case may be.

         SECTION 512. Control by Holders. The Holders of a majority in principal
amount of the  Outstanding  Securities  of any  series  shall  have the right to
direct the time,  method and place of conducting  any  proceeding for any remedy
available  to the  Trustee or  exercising  any trust or power  conferred  on the
Trustee with respect to the Securities of such series, provided that

         (1) such  direction  shall not be in  conflict  with any rule of law or
    with this Indenture, and

         (2) the Trustee may take any other action  deemed proper by the Trustee
    that is not inconsistent with such direction.

         SECTION 513.  Waiver of Past  Defaults.  The Holders of not less than a
majority in principal amount of the Outstanding  Securities of any series may on
behalf  of the  Holders  of all the  Securities  of such  series  waive any past
default  hereunder  with respect to such series and its  consequences,  except a
default

         (1) in the payment of the principal of (or premium, if any) or interest
    on any Security of such series  (including  any Security that is required to
    have been  purchased  


                                       67
<PAGE>


    pursuant to an Offer to Purchase that has been made by the Company), or

         (2) in respect of a covenant or  provision  hereof  that under  Article
    Nine cannot be modified or amended without the consent of the Holder of each
    Outstanding Security of such series affected.

         Upon any such waiver,  such default shall cease to exist, and any Event
of  Default  arising  therefrom  shall be deemed to have been  cured,  for every
purpose of this Indenture;  but no such waiver shall extend to any subsequent or
other default or impair any right consequent thereon.

         SECTION 514.  Undertaking for Costs. In any suit for the enforcement of
any right or remedy under this Indenture, or in any suit against the Trustee for
any action taken,  suffered or omitted by it as Trustee, a court may require any
party  litigant  in such  suit to file an  undertaking  to pay the costs of such
suit, and may assess costs against any such party litigant, in the manner and to
the extent provided in the Trust Indenture Act.

         SECTION 515.  Waiver of Stay or Extension  Laws. The Company  covenants
(to the extent that it may  lawfully do so) that it shall not at any time insist
upon,  or  plead,  or in any  manner  whatsoever  claim or take the  benefit  or
advantage of, any usury, stay or extension law wherever  enacted,  now or at any
time  hereafter in force,  which may affect the covenants or the  performance of
this  Indenture;  and the  Company  (to the extent  that it may  lawfully do so)
hereby  expressly  waives all benefit or advantage of any such law and covenants
that it shall not  hinder,  delay or impede the  execution  of any power  herein
granted to the Trustee,  but shall suffer and permit the execution of every such
power as though no such law had been enacted.

                                   ARTICLE SIX

                                   THE TRUSTEE

         SECTION 601.  Certain Duties and  Responsibilities.  (a) The duties and
responsibilities of the Trustee shall be as provided by the Trust Indenture Act.
Whether or not therein expressly so provided,  every provision of this Indenture
relating to the conduct or affecting the liability of or affording protection to
the Trustee shall be subject to the provisions of this Section 601.

         (b) Except during the continuance of an Event of Default,


                                       68
<PAGE>


         (1) the Trustee  undertakes to perform such duties and only such duties
    as are specifically set forth in this Indenture, and no implied covenants or
    obligations shall be read into this Indenture against the Trustee; and

         (2)  in  the  absence  of  bad  faith  on its  part,  the  Trustee  may
    conclusively  rely, as to the truth of the statements and the correctness of
    the opinions expressed  therein,  upon certificates or opinions furnished to
    the Trustee and conforming to the requirements of this Indenture; but in the
    case of any such  certificates or opinions that by any provision  hereof are
    specifically  required to be furnished to the Trustee,  the Trustee shall be
    under a duty to examine the same to determine whether or not they conform to
    the  requirements of this Indenture but need not confirm the accuracy of any
    calculations contained therein.

         (c) In case an Event of Default has  occurred  and is  continuing,  the
Trustee  shall  exercise  such of the  rights  and  powers  vested in it by this
Indenture,  and use the same  degree of care and skill in their  exercise,  as a
prudent man would exercise or use under the  circumstances in the conduct of his
own affairs.

         (d) No  provision of this  Indenture  shall be construed to relieve the
Trustee from liability for its own negligent  action,  its own negligent failure
to act, or its own willful misconduct, except that:

         (1) this  subsection  (d) shall not be construed to limit the effect of
    subsections (b) or (c) of this Section 601;

         (2) the Trustee  shall not be liable for any error of judgment  made in
    good  faith by a  Responsible  Officer,  unless it shall be proved  that the
    Trustee was negligent in ascertaining the pertinent facts;

         (3) the Trustee shall not be liable with respect to any action taken or
    omitted to be taken by it in good faith in accordance  with the direction of
    the Holders of a majority in principal amount of the Outstanding  Securities
    of any  series  relating  to the time,  method and place of  conducting  any
    proceeding for any remedy available to the Trustee,  or exercising any trust
    or power conferred upon the Trustee, under this Indenture; and

         (4) no provision of this Indenture  shall require the Trustee to expend
    or risk its own funds or  otherwise  incur any  financial  liability  in the
    performance of any of its 


                                       69
<PAGE>


    duties  hereunder,  or in the exercise of any of its rights or powers, if it
    shall have reasonable  grounds for believing that repayment of such funds or
    adequate  indemnity against such risk or liability is not reasonably assured
    to it.

         SECTION 602. Notice of Defaults; Notice of Acceleration. Within 90 days
after the  occurrence of any Event of Default with respect to the  Securities of
any series,  the Trustee shall  transmit by mail to all Holders,  as their names
and addresses appear in the Security  Register,  notice of such Event of Default
known to the  Trustee,  unless  such Event of  Default  shall have been cured or
waived;  provided  that,  except in the case of a default in any  payment of the
principal of (or premium, if any) or interest on any Security of such series and
any  payment  required  in  connection  with a  Change  of  Control  or an Asset
Disposition, the Trustee shall be protected in withholding such notice if and so
long as the board of directors,  the executive  committee or the trust committee
corporate or  Responsible  Officers of the Trustee in good faith  determine that
the  withholding  of  such  notice  is in the  interest  of the  Holders  of the
Securities of such series; and provided further that in the case of any Event of
Default  of the  character  specified  in  Section  501(5)  with  respect to the
Securities  of such  series,  no such notice to Holders  shall be given until at
least 30 days after the occurrence thereof.

         SECTION 603.  Certain  Rights of Trustee.  Subject to the provisions of
Section 601:

         (a) the Trustee may rely and shall be protected in acting or refraining
from acting upon any resolution,  certificate,  statement,  instrument, opinion,
report, notice, request, direction, consent, order, bond, debenture, note, other
evidence of indebtedness or other paper or document believed by it to be genuine
and to have been signed or presented by the proper party or parties;

         (b) any request,  order,  demand or direction of the Company  mentioned
herein shall be sufficiently evidenced by a Company Request or Company Order and
any  resolution  of the Board of Directors  may be  sufficiently  evidenced by a
Board Resolution;

         (c) whenever in the  administration of this Indenture the Trustee shall
deem it  desirable  that a matter  be  proved or  established  prior to  taking,
suffering or omitting any action  hereunder,  the Trustee (unless other evidence
be herein specifically prescribed) may, in the absence of bad faith on its part,
rely upon an Officers' Certificate;


                                       70
<PAGE>


         (d) the Trustee may consult with counsel and the written advice of such
counsel or any Opinion of Counsel shall be full and complete  authorization  and
protection in respect of any action  taken,  suffered or omitted by it hereunder
in good faith and in reliance thereon;

         (e) the Trustee  shall be under no  obligation  to exercise  any of the
rights or powers  vested in it by this  Indenture at the request or direction of
any of the  Holders of  Securities  of any series  pursuant  to this  Indenture,
unless such  Holders  shall have offered to the Trustee  reasonable  security or
indemnity against the costs,  expenses and liabilities that might be incurred by
it in compliance with such request or direction;

         (f) the Trustee shall not be bound to make any  investigation  into the
facts or matters stated in any resolution,  certificate,  statement, instrument,
opinion,  report, notice, request,  direction,  consent, order, bond, debenture,
note,  other  evidence  of  indebtedness  or other  paper or  document,  but the
Trustee, in its discretion,  may make such further inquiry or investigation into
such facts or matters as it may see fit, and, if the Trustee shall  determine to
make such further  inquiry or  investigation,  it shall be entitled  (subject to
reasonable  confidentiality  arrangements  as may be proposed by the Company) to
examine the books,  records and premises of the Company,  personally or by agent
or attorneys;

         (g) the Trustee may  execute any of the trusts or powers  hereunder  or
perform  any  duties  hereunder  either  directly  or by or  through  agents  or
attorneys  and the  Trustee  shall  not be  responsible  for any  misconduct  or
negligence  on the part of any agent or attorney  appointed  with due care by it
hereunder;

         (h) the Trustee  shall not be charged with  knowledge of any Default or
any Event of Default  with respect to  Securities  of any series for which it is
acting as Trustee  unless either (i) a Responsible  Officer of the Trustee shall
have actual  knowledge of the Default or Event of Default or (ii) written notice
of such Default or Event of Default  shall have been given to the Trustee by the
Company,  any  other  obligor  on  such  Securities  or by any  holder  of  such
Securities; and

         (i) the Trustee shall not be liable for any action  taken,  suffered or
omitted by it and believed by it to be  authorized  or within the  discretion or
rights or powers conferred upon it by this Indenture.

         SECTION 604. Not  Responsible  for Recitals or Issuance of  Securities.
The  recitals  contained  herein and in the  Securities,  except  the  Trustee's
certificates of authentication,


                                       71
<PAGE>

shall be taken as the  statements  of the  Company,  and the Trustee  assumes no
responsibility for their correctness. The Trustee makes no representations as to
the validity or sufficiency of this Indenture or of the Securities.  The Trustee
shall not be accountable for the use or application by the Company of Securities
or the proceeds thereof.

         SECTION  605. May Hold  Securities.  The  Trustee,  any  Authenticating
Agent,  any Paying  Agent,  any  Security  Registrar  or any other  agent of the
Company,  in its  individual  or any other  capacity,  may  become  the owner or
pledgee of Securities  and,  subject to Sections 608 and 613, may otherwise deal
with the  Company  with the same  rights it would  have if it were not  Trustee,
Authenticating Agent, Paying Agent, Security Registrar or such other agent.

         SECTION  606.  Money Held in Trust.  Money held by the Trustee in trust
hereunder need not be segregated  from other funds except to the extent required

         SECTION 607. Compensation and Reimbursement. The Company agrees:

         (1)  to  pay  to  the  Trustee  from  time  to  time  such   reasonable
    compensation as the Company and the Trustee shall from time to time agree in
    writing for all services rendered by it hereunder (which  compensation shall
    not be limited by any  provision of law in regard to the  compensation  of a
    trustee of an express trust);

         (2) except as otherwise  expressly  provided  herein,  to reimburse the
    Trustee  upon its request for all  reasonable  expenses,  disbursements  and
    advances incurred or made by the Trustee in accordance with any provision of
    this Indenture  (including the reasonable  compensation and the expenses and
    disbursements   of  its  agents  and  counsel)   except  any  such  expense,
    disbursement  or advance as may be  attributable  to its  negligence  or bad
    faith; and

         (3) to indemnify the Trustee in its individual capacity and each of its
    officers,  directors,  agents  and  counsel  for,  and to hold  it  harmless
    against,  any loss,  damage,  claim,  liability or expense  incurred without
    negligence  or  bad  faith  on  such  Person's  part,  arising  out of or in
    connection  with the acceptance or  administration  of this Indenture or the
    performance of any of its powers and duties  hereunder,  including the costs
    and  expenses  of  defending  itself  against  any  claim  or  liability  in


                                       72
<PAGE>


    connection  with the exercise or  performance of any of its powers or duties
    hereunder and complying with any process served upon the Trustee or any such
    other Person hereunder.

         The Trustee shall have a Lien prior to the  Securities  with respect to
all Property and funds held or collected by the Trustee hereunder for any amount
owing to it pursuant to this Section  607,  except with respect to funds held in
trust for the benefit of the Holders of particular Securities.

         When the Trustee incurs expenses or renders services in connection with
an Event of Default specified in Section 501(7) or Section 501(8),  the expenses
(including  the  reasonable  charges  and  expenses  of  its  counsel)  and  the
compensation   for  the  services  are  intended  to   constitute   expenses  of
administration  under any applicable Federal or state bankruptcy,  insolvency or
other similar law.

         The Company's  obligations  under this Section 607 and any Lien arising
hereunder shall survive the resignation or removal of the Trustee, the discharge
of the  Company's  obligations  pursuant to Article  Twelve,  any  rejection  or
termination of the Indenture under any Federal or state  bankruptcy,  insolvency
or other similar law or any other termination of this Indenture.

         SECTION 608. Conflicting Interests. If the Trustee has or shall acquire
a  conflicting  interest  within the  meaning of the Trust  Indenture  Act,  the
Trustee shall either eliminate such interest or resign, to the extent and in the
manner  provided by, and subject to the provisions  of, the Trust  Indenture Act
and this  Indenture.  There shall be excluded from the operation of this Section
608 (i) the  Indenture  dated as of March 24, 1994,  between the Company and IBJ
Schroder  Bank & Trust  Company,  as trustee,  governing  the  Company's 10 1/4%
Senior  Discount  Notes due 2004,  (ii) the Indenture  dated as of September 20,
1996,  between the Company and IBJ Schroder  Bank & Trust  Company,  as trustee,
governing  the Company's 9 1/2% Senior Notes due 2006 and (iii) any other series
of Securities governed by this Indenture.

         SECTION 609.  Corporate Trustee Required;  Eligibility.  There shall at
all  times be a  Trustee  hereunder  that  shall be a  Person  that is  eligible
pursuant to the Trust  Indenture  Act to act as such and has a combined  capital
and  surplus  of at least  $50,000,000  and its  Corporate  Trust  Office in the
Borough of Manhattan,  The City of New York and shall be subject to  supervision
or examination by Federal or State authority.  If such Person publishes  reports
of condition at least annually,  pursuant to law or to the  requirements of said
supervising  or examining  authority,  then for the purposes of this Section 609


                                       73
<PAGE>


and to the extent permitted by the Trust Indenture Act, the combined capital and
surplus of such Person shall be deemed to be its combined capital and surplus as
set forth in its most recent  report of condition so  published.  If at any time
the Trustee shall cease to be eligible in accordance with the provisions of this
Section  609,  it shall  resign  immediately  in the  manner and with the effect
hereinafter specified in this Article Six.

         SECTION 610. Resignation and Removal;  Appointment of Successor. (a) No
resignation or removal of the Trustee and no appointment of a successor  Trustee
pursuant to this  Article Six shall become  effective  until the  acceptance  of
appointment  by  the  successor   Trustee  in  accordance  with  the  applicable
requirements of Section 611.

         (b) The Trustee may resign at any time with  respect to  Securities  of
one or more  series by giving  written  notice  thereof  to the  Company.  If an
instrument  of  acceptance  by  a  successor  Trustee  in  accordance  with  the
applicable  requirements  of Section  611 shall not have been  delivered  to the
Trustee  within 30 days  after the  giving of such  notice of  resignation,  the
resigning  Trustee may  petition  any court of  competent  jurisdiction  for the
appointment  of a  successor  Trustee  with  respect to the  Securities  of such
series.

         (c)  The  Trustee  may be  removed  at any  time  with  respect  to the
Securities  of one or  more  series  by Act of  the  Holders  of a  majority  in
principal amount of the Outstanding Securities of such series,  delivered to the
Trustee and to the Company.

         (d) If at any time:

         (1) the  Trustee  shall fail to comply with  Section 608 after  written
    request  therefor  by the  Company or by any Holder who has been a bona fide
    Holder of a Security for at least six months, or

         (2) the Trustee shall cease to be eligible  under Section 609 and shall
    fail to resign after written request  therefor by the Company or by any such
    Holder, or

         (3) the Trustee shall become incapable of acting or shall be adjudged a
    bankrupt or insolvent or a receiver of the Trustee or of its property  shall
    be  appointed  or any public  officer  shall  take  charge or control of the
    Trustee or of its  property or affairs  for the  purpose of  rehabilitation,
    conservation or liquidation,


                                       74
<PAGE>


then,  in any such case,  (i) the Company by a Board  Resolution  may remove the
Trustee  with  respect to all  Securities,  or (ii)  subject to Section 514, any
Holder  who has been a bona fide  Holder of a  Security  for at least six months
may, on behalf of himself and all others similarly situated,  petition any court
of  competent  jurisdiction  for the removal of the Trustee  with respect to all
Securities and the appointment of a successor Trustee or Trustees.

         (e) If the Trustee  shall  resign,  be removed or become  incapable  of
acting,  or if a vacancy shall occur in the office of Trustee for any cause with
respect  to the  Securities  of one or  more  series,  the  Company,  by a Board
Resolution,  shall  promptly  appoint a successor  Trustee  with  respect to the
Securities of that or those series.  If, within one year after such resignation,
removal or incapability,  or the occurrence of such vacancy, a successor Trustee
with  respect to the  Securities  of any series shall be appointed by Act of the
Holders of a majority in principal amount of the Outstanding  Securities of such
series delivered to the Company and the retiring Trustee,  the successor Trustee
so  appointed  shall,  forthwith  upon its  acceptance  of such  appointment  in
accordance with the applicable requirements of Section 611, become the successor
Trustee and supersede the  successor  Trustee with respect to the  Securities of
such series  appointed by the Company.  If no successor  Trustee with respect to
the  Securities of any series shall have been so appointed by the Company or the
Holders and accepted appointment in accordance with the applicable  requirements
of Section 611, any Holder who has been a bona fide Holder of a Security of such
series  for at least  six  months  may,  on  behalf of  himself  and all  others
similarly  situated,  petition  any  court  of  competent  jurisdiction  for the
appointment  of a  successor  Trustee  with  respect to the  Securities  of such
series.

appointment  hereunder of a successor  Trustee  with respect to all  Securities,
every  successor  Trustee  appointed  hereunder  shall execute,  acknowledge and

Trustee,  without any further act, deed or conveyance,  shall become vested with
all the  rights,  powers,  trusts and duties of the  retiring  Trustee;  but, on
request of the Company or the successor  Trustee,  such retiring  Trustee shall,
upon payment of any amounts then due under  Section 607,  execute and deliver an
instrument  transferring  to such successor  Trustee all the rights,  powers and
trusts of the retiring  Trustee and shall duly  assign,  transfer and deliver to
such  successor  Trustee all  property and money held by such  retiring  Trustee
hereunder,  subject,  nevertheless, to its Lien, if any, provided for in Section
607.

         (b) In case of the  appointment  hereunder of a successor  Trustee with
respect to the Securities of one or more (but not all) series, the Company,  the

pursuant to Article Nine hereof,  wherein each  successor  Trustee  shall accept
such  appointment  and which  (1)  shall  contain  such  provisions  as shall be
necessary  or  desirable  to  transfer  and  confirm  to,  and to vest in,  each
successor  Trustee all the  rights,  powers,  trusts and duties of the  retiring
Trustee  with  respect to the  Securities  of that or those  series to which the
appointment of such successor  Trustee  relates,  (2) if the retiring Trustee is
not retiring with respect to all  Securities,  shall contain such  provisions as
shall be deemed  necessary or desirable to confirm that all the rights,  powers,
trusts and duties of the retiring Trustee with respect to the Securities of that
or those series as to which the retiring  Trustee is not retiring shall continue
to be vested in the retiring Trustee,  and (3) shall add to or change any of the
provisions of this  Indenture as shall be necessary to provide for or facilitate
the  administration  of the trusts hereunder by more than one Trustee,  it being
understood  that  nothing  herein  or  in  such  supplemental   indenture  shall
constitute  such  Trustees  co-trustees  of the same  trust  and that  each such
Trustee shall be trustee of a trust or trusts hereunder  separate and apart from
any trust or trusts hereunder  administered by any other such Trustee;  and upon
the execution and delivery of such  supplemental  indenture the  resignation  or
removal of the retiring  Trustee shall become  effective to the extent  provided
therein  and each such  successor  Trustee,  without any  further  act,  deed or
conveyance,  shall become vested with all the rights,  powers, trusts and duties
of the retiring  Trustee with respect to the  Securities of that or those series
to which the appointment of such successor  Trustee relates;  but, on request of
the Company or any successor  Trustee,  such retiring Trustee shall duly assign,
transfer  and deliver to such  successor  Trustee all property and money held by
such  retiring  Trustee upon  payment of any amounts then due under  Section 607
hereunder  with respect to the  Securities  of that or those series to which the
appointment of such successor  Trustee 


                                       76
<PAGE>


relates,  subject,  nevertheless,  to its Lien, if any,  provided for in Section
607.

         (c) Upon  request of any such  successor  Trustee,  the  Company  shall
execute  any and all  instruments  for more fully and  certainly  vesting in and
confirming to such successor Trustee all such rights, powers and trusts.

         (d) No successor  Trustee  shall accept its  appointment  unless at the
time of such acceptance  such successor  Trustee shall be qualified and eligible
under this Article.

         SECTION  612.  Merger,  Conversion,   Consolidation  or  Succession  to
Business.  Any corporation  into which the Trustee may be merged or converted or
with which it may be consolidated, or any corporation resulting from any merger,
conversion  or  consolidation  to which  the  Trustee  shall be a party,  or any
corporation  succeeding to all or substantially all the corporate trust business
of the Trustee,  shall be the successor of the Trustee hereunder,  provided that
such  corporation  shall be otherwise  qualified and eligible under this Article
Six, without the execution or filing of any paper or any further act on the part
of  any  of  the  parties  hereto.  In  case  any  Securities  shall  have  been
authenticated,  but not delivered,  by the Trustee then in office, any successor
by merger,  conversion or consolidation to such authenticating Trustee may adopt
such  authentication  and deliver the Securities so authenticated  with the same
effect as if such successor Trustee had itself authenticated such Securities.

         SECTION 613. Preferential  Collection of Claims Against Company. If and
when the  Trustee  shall be or become a creditor  of the  Company  (or any other
obligor upon the Securities),  the Trustee shall be subject to the provisions of
the Trust  Indenture Act regarding the  collection of claims against the Company
(or any such other obligor).

         SECTION 614. Appointment of Authenticating  Agent. The Trustee may from
time to time  appoint an  Authenticating  Agent or Agents with respect to one or
more  series of  Securities  that  shall be  authorized  to act on behalf of the
Trustee to authenticate Securities of such series issued upon original issue and
upon  exchange,  registration  of  transfer  or  partial  redemption  or partial
purchase or pursuant to Section 308, and  Securities so  authenticated  shall be
entitled to the benefits of this Indenture and shall be valid and obligatory for
all purposes as if authenticated by the Trustee hereunder. Wherever reference is
made in this Indenture to the  authentication  and delivery of Securities by the
Trustee or the Trustee's certificate of authentication,  such reference shall be
deemed to include


                                       77
<PAGE>


authentication and delivery on behalf of the Trustee by an Authenticating  Agent
and a  certificate  of  authentication  executed  on behalf of the Trustee by an
Authenticating  Agent.  Each  Authenticating  Agent shall be  acceptable  to the
Company and shall at all times be a  corporation  organized  and doing  business
under  the laws of the  United  States of  America,  any  State  thereof  or the
District of Columbia, authorized under such laws to act as Authenticating Agent,
having a combined  capital and surplus of not less than  $50,000,000 and subject
to  supervision  or  examination  by  Federal  or  State   authority.   If  such
Authenticating Agent publishes reports of condition at least annually,  pursuant
to law or to the requirements of said supervising or examining  authority,  then
for the purposes of this  Section 614, the combined  capital and surplus of such
Authenticating  Agent shall be deemed to be its combined  capital and surplus as
set forth in its most recent report of condition so published. If at any time an
Authenticating  Agent  shall  cease  to  be  eligible  in  accordance  with  the
provisions  of  this  Section  614,  such  Authenticating   Agent  shall  resign
immediately in the manner and with the effect specified in this Section 614.

         Any  corporation  into which an  Authenticating  Agent may be merged or
converted or with which it may be  consolidated,  or any  corporation  resulting
from any merger,  conversion or consolidation to which such Authenticating Agent
shall be a party,  or any  corporation  succeeding  to the  corporate  agency or
corporate  trust business of an  Authenticating  Agent,  shall continue to be an
Authenticating  Agent,  provided such  corporation  shall be otherwise  eligible
under this Section,  without the execution or filing of any paper or any further
act on the  part  of the  Trustee  or the  Authenticating  Agent.  In  case  any
Securities   shall  have  been   authenticated,   but  not  delivered,   by  the
Authenticating  Agent then in office,  any  successor by merger,  conversion  or
consolidation to such  Authenticating  Agent may adopt such  authentication  and
deliver  the  Securities  so  authenticated  with  the  same  effect  as if such
successor Authenticating Agent had itself authenticated such Securities.

         An Authenticating  Agent for any series of Securities may resign at any
time by giving  written notice thereof to the Trustee for such series and to the
Company.  The Trustee for any series of Securities may at any time terminate the
agency of an  Authenticating  Agent by giving  written  notice  thereof  to such
Authenticating  Agent  and to the  Company.  Upon  receiving  such a  notice  of
resignation  or  upon  such  a  termination,   or  in  case  at  any  time  such
Authenticating  Agent  shall  cease  to  be  eligible  in  accordance  with  the
provisions  of this  Section  614,  the  Trustee  for such  series may appoint a
successor Authenticating Agent that shall be acceptable to the Company and shall
give notice of such  appointment  in the manner  provided in Section 106, to all
Holders


                                       78
<PAGE>


of Securities of the series as their names and addresses  appear in the Security
Register. Any successor  Authenticating Agent upon acceptance of its appointment
hereunder  shall  become  vested with all the  rights,  powers and duties of its
predecessor   hereunder,   with  like  effect  as  if  originally  named  as  an
Authenticating  Agent.  No  successor  Authenticating  Agent shall be  appointed
unless eligible under the provisions of this Section 614.

         The  Company  agrees to pay to each  Authenticating  Agent from time to
time reasonable compensation for its services under this Section.

         The provisions of Sections 311, 604 and 605 shall be applicable to each
Authenticating Agent.

         If an  appointment  with respect to one or more series is made pursuant
to this Section 614, the Securities of such series may have endorsed thereon, in
addition  to or in lieu  of the  Trustee's  certificate  of  authentication,  an
alternative certificate of authentication in the following form:

         This is one of the Securities of the series designated therein referred
to in the within-mentioned Indenture.

    thereon  is  payable,  or  impair  the  right  to  institute  suit  for  the
    enforcement of any such payment on or after the Stated Maturity thereof, or

         (2)  reduce  the  percentage  in  principal  amount of the  Outstanding
    Securities  of any series,  the consent of whose Holders is required for any
    such supplemental indenture, or the consent of whose Holders is required for
    any  waiver  with  respect  to  such  series  (of  compliance  with  certain
    provisions  of this  Indenture  or  certain  defaults  hereunder  and  their
    consequences) provided for in this Indenture, or

         (3) modify the  obligations  of the  Company to make Offers to Purchase
    from the Excess  Proceeds of Asset  Dispositions or upon a Change of Control
    or to modify the definitions related thereto, or

         (4)  subordinate  a right of payment,  or  otherwise  subordinate,  the
    Securities to any other indebtedness, or

         (5) modify any of the  provisions  of this Section 902,  Section 513 or
    Section  1020,  except to increase  any such  percentage  or to provide that
    certain  other  provisions  of this  Indenture  cannot be modified or waived
    without  the  consent of the Holder of each  Outstanding  Security  affected
    thereby.

         It shall not be necessary for any Act of Holders under this Section 902
to approve the particular form of any proposed  supplemental  indenture,  but it
shall be sufficient if such Act shall approve the substance thereof.

         A  supplemental  indenture  which changes or eliminates any covenant or
other  provision of this Indenture  which has expressly been included solely for
the benefit of one or more  particular  series of Securities,  or which modifies
the rights of the Holders of  Securities  of such  series  with  respect to such
covenant or other provision, shall be deemed not to affect the rights under this
Indenture of the Holders of Securities of any other series.

         After a supplemental  indenture under this Section  becomes  effective,
the  Company  shall mail to the  Holders of any  series of  Securities  affected
thereby a notice briefly describing the supplemental  indenture.  Any failure of
the Company to mail such notice, or any default therein,  shall not, however, in
any way impair or affect the validity of any such supplemental indenture.

         In  connection  with any  supplemental  indenture  or waiver under this
Article  Nine,  the Company  may,  but shall not be  obligated  to, offer to any
Holder  who  consents  to  such  supplemental  indenture,  or  to  all  Holders,
consideration for such Holder's consent to such supplemental indenture.

         SECTION 903.  Execution of Supplemental  Indentures.  In executing,  or
accepting the additional trusts created by, any supplemental indenture permitted
by this  Article or the  modifications  thereby  of the  trusts  created by this
Indenture,  the Trustee  shall be entitled to receive,  and  (subject to Section
601) shall be fully  protected in relying  upon,  an Opinion of Counsel  stating
that the execution of such supplemental  indenture is authorized or permitted by
this  Indenture.  The Trustee may, but shall not be obligated to, enter into any
such  supplemental  indenture  that affects the Trustee's own rights,  duties or
immunities under this Indenture or otherwise.

         SECTION 904. Effect of Supplemental  Indentures.  Upon the execution of
any  supplemental  indenture  under this Article Nine,  this Indenture  shall be
modified in accordance therewith,  and such supplemental  indenture shall form a
part  of this  Indenture  for all  purposes;  and  every  Holder  of  Securities
theretofore or thereafter  authenticated and delivered  hereunder shall be bound
thereby, unless it makes a change described in any of clauses (1) through (5) of
Section  902, in which case,  the  supplemental  indenture  shall bind only each
Holder of a Security who has  consented to it and every  subsequent  Holder of a
Security or portion of a Security that evidences the same Debt as the consenting
Holder's Security;  provided that any such waiver shall not impair or affect the
right of any Holder to receive  payment of principal and premium of and interest
on a Security,  on or after the respective  dates set for such amounts to become
due and 


                                        86
<PAGE>


payable,  or to bring suit for the  enforcement  of any such payment on or after
such respective dates.

         SECTION 905.  Conformity with Trust  Indenture Act. Every  supplemental
indenture   executed  pursuant  to  this  Article  Nine  shall  conform  to  the
requirements of the Trust Indenture Act.

         SECTION  906.  Reference  in  Securities  to  Supplemental  Indentures.
Securities of any series  authenticated and delivered after the execution of any
supplemental  indenture pursuant to this Article Nine may, and shall if required
by the Trustee, bear a notation in form approved by the Trustee as to any matter
provided for in such supplemental  indenture. If the Company shall so determine,
new  Securities  of any series so modified as to conform,  in the opinion of the
Trustee and the Company, to any such supplemental  indenture may be prepared and
executed  by the  Company  and  authenticated  and  delivered  by the Trustee in
exchange for  Outstanding  Securities  of such  series.  Any failure to make the
appropriate  notation on a new  Security  shall not affect the  validity of such
Security.


                                   ARTICLE TEN

                                    COVENANTS

         SECTION 1001. Payment of Principal,  Premium and Interest.  The Company
shall  duly  and  punctually  pay the  principal  of (and  premium,  if any) and
interest on the  Securities of each series in accordance  with the terms of such
series of Securities and this Indenture.

         SECTION  1002.  Maintenance  of Office or  Agency.  The  Company  shall
maintain in the Borough of Manhattan,  The City of New York, an office or agency
where  Securities  of any series may be  presented or  surrendered  for payment,
where  Securities of any series may be surrendered for  registration of transfer
or exchange  and where  notices and demands to or upon the Company in respect of
the Securities of any series and this Indenture may be served. The Company shall
give prompt written notice to the Trustee of the location, and any change in the
location,  of such office or agency.  If at any time the  Company  shall fail to
maintain any such required office or agency or shall fail to furnish the Trustee
with the address thereof,  such presentations,  surrenders,  notices and demands
may be made or served at the  Corporate  Trust  Office of the  Trustee,  and the
Company  hereby   appoints  the  Trustee  as  its  agent  to  receive  all  such
presentations,  surrenders, notices and demands. In the event any 


                                       87
<PAGE>


such notice or demands are so made or served on the Trustee,  the Trustee  shall
promptly forward copies thereof to the Company.

         The  Company  may also from time to time  designate  one or more  other
offices or agencies  (in or outside the  Borough of  Manhattan,  The City of New
York) where the Securities of one or more series may be presented or surrendered
for  any  or  all  such  purposes  and  may  from  time  to  time  rescind  such
designations;  provided  that no such  designation  or  rescission  shall in any
manner  relieve the Company of its obligation to maintain an office or agency in
the  Borough  of  Manhattan,  The  City of New  York,  in  accordance  with  the
requirements  for  Securities  of any  series,  or set  forth  herein,  for such
purposes.  The Company  shall give prompt  written  notice to the Trustee of any
such  designation  or  rescission  and of any change in the location of any such
other office or agency. The Company hereby initially  designates for each series
of Securities,  the Corporate  Trust Office of the Trustee as such office of the
Company.

         SECTION 1003.  Money for Security  Payments to be Held in Trust. If the
Company shall at any time act as its own Paying Agent with respect to any series
of any Securities, it shall, on or before each due date of the principal of (and
premium, if any) or interest on any of the Securities of that series,  segregate
and  hold in  trust  for the  benefit  of the  Persons  entitled  thereto  a sum
sufficient  to pay the principal  (and premium,  if any) or interest so becoming
due until such sums shall be paid to such  Persons or  otherwise  disposed of as
herein  provided and shall promptly  notify the Trustee of its action or failure
so to act.

         Whenever  the  Company  shall  have one or more  Paying  Agents for any
series,  it shall,  prior to each due date of the principal of (and premium,  if
any) or interest on any Securities of that series, deposit with a Paying Agent a
sum  sufficient  to pay the  principal  (and  premium,  if any) or  interest  so
becoming  due, such sum to be held as provided by the Trust  Indenture  Act, and
(unless such Paying Agent is the Trustee) the Company shall promptly  notify the
Trustee of its action or failure so to act.

         The Company  shall  cause each  Paying  Agent other than the Trustee to
execute  and  deliver to the Trustee an  instrument  in which such Paying  Agent
shall agree with the Trustee,  subject to the  provisions  of this Section 1003,
that  such  Paying  Agent  shall (i)  comply  with the  provisions  of the Trust
Indenture Act applicable to it as Paying Agent,  (ii) give the Trustee notice of
any default by the Company (or other obligor upon the  Securities) in the making
of any payment of principal of (and  premium,  if any) or interest in respect of
the  Securities  and (iii) during the  continuance of any default by the Company
(or any other  obligor  upon the  Securities)  in the  making of any  payment in


                                       88
<PAGE>


respect of the Securities,  upon the written  request of the Trustee,  forthwith
pay to the Trustee all sums held in trust by such Paying Agent as such.

         The  Company  may at  any  time,  for  the  purpose  of  obtaining  the
satisfaction  and discharge of this Indenture or for any other purpose,  pay, or
by Company Order direct any Paying Agent to pay, to the Trustee all sums held in
trust by the Company or such Paying  Agent,  such sums to be held by the Trustee
upon the same  trusts as those upon which such sums were held by the  Company or
such Paying  Agent;  and,  upon such payment by any Paying Agent to the Trustee,
such Paying Agent shall be released from all further  liability  with respect to
such money.

         Except as otherwise provided in the Securities of any series, any money
deposited with the Trustee or any Paying Agent, or then held by the Company,  in
trust for the payment of the principal of (and  premium,  if any) or interest on
any  Security  of any series and  remaining  unclaimed  for two years after such
principal (and premium,  if any) or interest has become due and payable shall be
paid to the Company on Company  Request,  or (if then held by the Company) shall
be discharged from such trust; and the Holder of such Security shall thereafter,
as an unsecured general creditor,  look only to the Company for payment thereof,
and all liability of the Trustee or such Paying Agent with respect to such trust
money shall  thereupon  cease;  provided  that the Trustee or such Paying Agent,
before  being  required  to make any such  repayment,  may at the expense of the
Company  cause to be  published  once,  in a newspaper  published in the English
language,  customarily published on each Business Day and of general circulation
in The City of New York, or mail to such Holder, or both, notice that such money
remains unclaimed and that, after a date specified  therein,  which shall not be
less than 30 days from the date of such  publication,  any unclaimed  balance of
such money then remaining shall be repaid to the Company.

         SECTION 1004. Existence. Subject to Article Eight, the Company shall do
or cause to be done all things  necessary to preserve and keep in full force and
effect its corporate  existence,  rights  (charter and  statutory)  and material
franchises; provided that the Company shall not be required to preserve any such
right or franchise if the Board of Directors in good faith shall  determine that
the  preservation  thereof is no longer desirable in the conduct of the business
of the Company and that the loss thereof does not  materially  adversely  affect
the Holders.

         SECTION 1005.  Maintenance of  Properties.  The Company shall cause all
material  properties  used or  useful  in the  conduct  of its  business  or the
business of any Restricted Subsidiary and


                                       89
<PAGE>

any Eligible Joint Venture to be maintained and kept in good  condition,  repair
and working order and supplied  with all necessary  equipment and shall cause to
be  made  all  necessary  repairs,  renewals,   replacements,   betterments  and
improvements  thereof, all as in the judgment of the Company may be necessary so
that the  business  carried  on in  connection  therewith  may be  properly  and
advantageously  conducted  at all times;  provided  that nothing in this Section
1005 shall prevent the Company from  discontinuing  the operation or maintenance
of any of such material or properties  or,  subject to the provisions of Section
1015,  disposing  of any of them if  such  discontinuance  or  disposal  is,  as
determined  by the  Company  in good  faith,  desirable  in the  conduct  of its
business or the business of any  Restricted  Subsidiary  and does not materially
adversely affect the Holders,  provided that the Restricted Subsidiaries and the
Eligible  Joint Ventures of the Company shall not be required to comply with the
foregoing provisions of this Section 1005 if they are prevented or restricted in
doing so by the terms of any loan or financing agreement,  any charter document,
partnership or joint venture agreement or any other agreement or instrument, all
of which are expressly acknowledged to take precedence over the terms hereof.

         SECTION 1006.  Payment of Taxes and Other Claims. The Company shall pay
or  discharge  or cause to be paid or  discharged,  before the same shall become
delinquent,  (1) all  taxes,  assessments  and  governmental  charges  levied or
imposed  upon the  Company  or any of its  Restricted  Subsidiaries  or upon the
income,   profits  or  property  of  the  Company  or  any  of  its   Restricted
Subsidiaries,  and (2) all lawful claims for labor, materials and supplies that,
if unpaid, might by law become a Lien upon the property of the Company or any of
its Restricted Subsidiaries;  provided that the Company shall not be required to
pay or discharge  or cause to be paid or  discharged  any such tax,  assessment,
charge or claim whose amount,  applicability  or validity is being  contested in
good faith by appropriate  proceedings and for which disputed  amounts  adequate
reserves have been accrued to the extent required by GAAP.

         SECTION 1007.  Maintenance of Insurance.  The Company shall,  and shall
cause its  Restricted  Subsidiaries  and the Eligible Joint Ventures to, keep at
all  times  all of their  Properties  that are of an  insurable  nature  insured
against loss or damage with insurers  believed by the Company to be  responsible
to the  extent  that  Property  of  similar  character  is usually so insured by
Persons  similarly  situated and owning like  Properties in accordance with good
business   practice.   The  Company  shall,   and  shall  cause  its  Restricted
Subsidiaries  and the Eligible Joint Ventures to, use the proceeds from any such
insurance policy to repair, replace or otherwise restore all material Properties
to which such proceeds  relate,  provided that the 


                                       90
<PAGE>

Company shall not be required to repair,  replace or otherwise  restore any such
material  Property if the Company in good faith determines that such inaction is
desirable  in the  conduct of the  business  of the  Company  or any  Restricted
Subsidiary and does not materially  adversely  affect the Holders,  and provided
further  that  the  Company  (only  in  respect  of  agreements   governing  its
Non-Recourse Debt), the Restricted  Subsidiaries and the Eligible Joint Ventures
of the  Company  shall not be required  to apply  insurance  proceeds to repair,
replace or restore any material  Property if they are prevented or restricted in
doing so by the terms of any loan or financing agreement,  any charter document,
partnership or joint venture agreement or any other agreement or instrument, all
of which are expressly acknowledged to take precedence over the terms hereof.

         The  Company  may,  and may  permit  its  Restricted  Subsidiaries  and
Eligible Joint  Ventures to, adopt such other plan or method of  protection,  in
lieu of or supplemental to insurance with insurers, whether by the establishment
of an insurance  fund or reserve to be held and applied to make good losses from
casualties, or otherwise,  conforming to the system of self-insurance maintained
by Persons  similarly  situated  and owning like  Properties  and which does not
materially  adversely affect the Holders, as may be determined by the Company in
good faith.

         SECTION 1008.  Limitation on Debt.  (a) The Company shall not Incur any
Debt, including  Acquisition Debt, unless, after giving effect to the Incurrence
of such Debt and the receipt and  application  of the  proceeds  therefrom,  the
Fixed Charge Ratio of the Company would be equal to or greater than 2.0 to 1.

         (b) Notwithstanding the provisions of Section 1008(a),  the Company may
Incur each and all of the following:  (i) Company Refinancing Debt, (ii) Debt of
the Company to any of its Restricted  Subsidiaries or any Eligible Joint Venture
that is  expressly  subordinated  in right of payment to the  Securities  of all
series, provided that any transfer of such Debt by a Restricted Subsidiary or an
Eligible Joint Venture (other than to another  Restricted  Subsidiary or another
Eligible Joint Venture), or any transfer of the Company's ownership interest, or
a portion thereof, in such Restricted  Subsidiary or such Eligible Joint Venture
or the interest, or a portion thereof, of Kiewit in a Permitted Joint Venture or
an  Eligible  Joint  Venture  (which  transfer  has the effect of  causing  such
Restricted Subsidiary or such Eligible Joint Venture to cease to be a Restricted
Subsidiary or an Eligible Joint Venture, as the case may be), shall be deemed to
be an Incurrence of Debt that is subject to the  provisions of this Section 1008
other than this clause (ii),


                                       91
<PAGE>

(iii)  Debt  in an  aggregate  principal  amount  not  to  exceed  $100  million
outstanding  at any one time may be  issued  under or in  respect  of  Permitted
Working Capital Facilities, (iv) Non-Recourse Debt Incurred in respect of one or
more  Permitted  Facilities  in  which  the  Company  has a direct  or  indirect
interest, (v) Debt in respect of Currency Protection Agreements or Interest Rate
Protection  Agreements,  (vi) Purchase  Money Debt,  provided that the amount of
such Debt (net of any original  issue  discount) does not exceed 90% of the fair
market  value of the  Property  acquired,  (vii) the  Securities  and other Debt
outstanding  as of the  Issue  Date of the  Securities  (other  than Debt to the
extent that it is extinguished,  retired,  defeased or repaid in connection with
the original  issuance of the  Securities),  including  Debt that is Incurred in
respect of  interest or discount  on such Debt (or  Redeemable  Stock  issued as
dividends in respect of Redeemable Stock) pursuant to the terms of the agreement
or instrument that governs such Debt (or such Redeemable  Stock) as in effect on
the Issue Date of the  Securities  and  (viii)  Debt in an  aggregate  principal
amount not to exceed $75 million outstanding at any one time.

         SECTION 1009.  Limitation on Subsidiary Debt. (a) The Company shall not
permit any of its Restricted  Subsidiaries  or any Eligible  Joint  Venture,  to
Incur any Debt.

         (b) Notwithstanding the provisions of Section 1009(a),  each and all of
the  following  Debt may be Incurred by a Restricted  Subsidiary  or an Eligible
Joint Venture: (i) Debt outstanding as of the Issue Date of the Securities, (ii)
Debt owed by a Restricted Subsidiary or an Eligible Joint Venture to the Company
or another  Restricted  Subsidiary  of the  Company or  another  Eligible  Joint
Venture  that  either  directly  or  indirectly  owns  all or a  portion  of the
Company's  interest in, or directly or indirectly  is owned by, such  Restricted
Subsidiary  or  such  Eligible  Joint  Venture,   as  the  case  may  be,  (iii)
Non-Recourse  Debt  Incurred  in  respect of one or more  Permitted  Facilities,
provided that such  Restricted  Subsidiary or such Eligible  Joint Venture has a
direct or indirect interest (which may include  Construction  Financing provided
by the  Company to the  extent  permitted  under  Section  1010 as a  "Permitted
Investment") in one or more of such Permitted Facilities in respect of which one
or more  Restricted  Subsidiaries or Eligible Joint Ventures shall have a direct
or indirect interest,  (iv) Subsidiary Refinancing Debt, (v) Acquired Debt, (vi)
Debt in respect of Currency  Protection  Agreements or Interest Rate  Protection
Agreements,   (vii)  Permitted   Funding  Company  Loans  and  (viii)  Permitted
Facilities  Debt,  provided  that at the time of  Incurrence  thereof  and after
giving  effect  to  the  application  of the  proceeds  thereof,  the  aggregate
principal  amount of  Permitted  Facilities  


                                       92
<PAGE>

Debt shall not exceed 15% of total  consolidated Debt of the Company computed in
accordance with GAAP.

         SECTION 1010. Limitation on Restricted Payments.  (a) The Company shall
not,  and shall not permit any of its  Restricted  Subsidiaries  or any Eligible
Joint Venture to, directly or indirectly,  make any Restricted Payment unless at
the time of such Restricted Payment and after giving effect thereto (a) no Event
of  Default  and no event  that,  after the giving of notice or lapse of time or
both, would become an Event of Default, has occurred and is continuing,  (b) the
Company could Incur at least $1 of Debt under Section 1008 and (c) the aggregate
amount  of  all  Restricted  Payments  made  by  the  Company,   its  Restricted
Subsidiaries  and the Eligible Joint Ventures (the amount so made, if other than
in cash,  to be  determined  in good faith by the Chief  Financial  Officer,  as
evidenced by an  Officers'  Certificate,  or, if more than $30  million,  by the
Board of Directors, as evidenced by a Board resolution) after March 24, 1994, is
less than the sum (without  duplication) of (i) 50% of the Adjusted Consolidated
Net  Income of the  Company  for the  period  (taken as one  accounting  period)
beginning on the first day of the first  fiscal  quarter that begins after March
24, 1994 and ending on the last day of the fiscal quarter  immediately  prior to
the date of such  calculation,  provided that if throughout  any fiscal  quarter
within such period the Ratings Categories applicable to the Securities are rated
Investment  Grade by S&P and  Moody's  (or if both do not  make a rating  of the
Securities  publicly  available,  an equivalent Rating Category is made publicly
available by another Rating Agency),  then 100% (instead of 50%) of the Adjusted
Consolidated  Net Income (if more than zero) with respect to such fiscal quarter
shall be included  pursuant to this clause (i),  and  provided  further  that if
Adjusted  Consolidated  Net Income for such period is less than zero, then minus
100% of the amount of such net loss,  plus (ii) 100% of the  aggregate  net cash
proceeds  received  by the  Company  from and after  March 24, 1994 from (A) the
issuance and sale (other than to a Restricted  Subsidiary  or an Eligible  Joint
Venture) of its Capital Stock (excluding Redeemable Stock, but including Capital
Stock other than Redeemable  Stock issued upon conversion of, or in exchange for
Redeemable Stock or securities  other than its Capital Stock),  (B) the issuance
and sale or the exercise of warrants, options and rights to purchase its Capital
Stock (other than Redeemable Stock) and (C) the issuance and sale of convertible
Debt upon the conversion of such convertible Debt into Capital Stock (other than
Redeemable  Stock),  but excluding  the net proceeds  from the  issuance,  sale,
exchange,  conversion  or other  disposition  of its  Capital  Stock (I) that is
convertible  (whether at the option of the Company or the holder thereof or upon
the  happening of any event) into (x) any security  other than its Capital Stock
or (y) its Redeemable Stock or (II) that is 


                                       93
<PAGE>


         Capital Stock  referred to in clauses (ii) and (iii) of the  definition
of "Permitted Payment", plus (iii) the net reduction in Investments of the types
specified in clauses (iv) and (v) of the definition of "Restricted Payment" that
result from  payments of interest on Debt,  dividends,  or repayment of loans or
advances,  the proceeds of the sale or  disposition  of the  Investment or other
return of the amount of the original  Investment to the Company,  the Restricted
Subsidiary or the Eligible Joint Venture that made the original  Investment from
the Person in which such  Investment  was made,  provided that (x) the aggregate
amount of such payments  shall not exceed the amount of the original  Investment
by the Company or such Restricted  Subsidiary that reduced the amount  available
pursuant to this clause (c) for making Restricted Payments and (y) such payments
may be added  pursuant to this clause (iii) only to the extent such payments are
not included in the calculation of Adjusted  Consolidated  Net Income,  provided
further that if  Investments  of the types  specified in clauses (iv) and (v) of
the  Definition  of  "Restricted  Payment" have been made in any Person and such
Person thereafter becomes a Restricted  Subsidiary or an Eligible Joint Venture,
then the  aggregate  amount of such  Investment  (to the  extent  that they have
reduced the amount available  pursuant to this clause (c) for making  Restricted
Payments),  net of the amounts  previously  added pursuant to this clause (iii),
may be added to the amount available for making Restricted  Payments,  plus (iv)
an amount equal to the principal  amount of Debt of the Company  extinguished in
connection with the conversion into Common Stock of the Company of the Company's
5%  Convertible  Subordinated  Debentures  due  2000  and its  9.5%  Convertible
Subordinated  Debenture due 2003. The foregoing clause (c) shall not prevent the
payment of any dividend within 60 days after the date of its declaration if such
dividend could have been made on the date of its declaration  without  violation
of the provisions of this Section 1010(a).

         (b) None of the  Company,  any of its  Restricted  Subsidiaries  or any
Eligible  Joint  Venture  shall be deemed to have made an Investment at the time
that a Person  that is a  Restricted  Subsidiary  of the  Company or an Eligible
Joint Venture ceases to be a Restricted  Subsidiary or an Eligible Joint Venture
(other  than as a result  of a  Restricted  Subsidiary  being  designated  as an
Unrestricted  Subsidiary),  although  any  subsequent  Investment  made  by  the
Company, its Restricted  Subsidiaries and Eligible Joint Ventures in such Person
shall be Investments that shall be subject to the foregoing paragraph unless and
until such time as such Person  becomes a Restricted  Subsidiary  or an Eligible
Joint  Venture.   Notwithstanding  the  foregoing,  (i)  the  designation  of  a
Restricted Subsidiary as an Unrestricted  Subsidiary,  in the manner provided in
the definition of "Unrestricted  Subsidiary,"  shall be an Investment that shall


                                       94
<PAGE>


be subject to the  foregoing  paragraph  and (ii) the transfer of the  Company's
interest  (or  portion  thereof)  in an  entity  that has been  deemed  to be an
Eligible  Joint Venture  directly or indirectly  to an  Unrestricted  Subsidiary
shall be an Investment (to the extent of the interest transferred) that shall be
subject to the foregoing paragraph.

         SECTION 1011.  Limitation on Transactions with Affiliates.  The Company
shall  not,  and shall not  permit  any of its  Restricted  Subsidiaries  or any

(including,  but not limited to, the purchase, sale or exchange of Property, the
making of any  Investment,  the giving of any  Guarantee or the rendering of any
service) with any Affiliate of the Company,  such Restricted  Subsidiary or such
Eligible  Joint  Venture,  as  the  case  may  be,  unless  (i)  such  business,
transaction  or series of related  transactions  is in the best  interest of the
Company,  such Restricted  Subsidiary or such Eligible Joint Venture,  (ii) such
business,  transaction  or series of  related  transactions  is on terms no less
favorable to the Company,  such  Restricted  Subsidiary or such  Eligible  Joint
Venture  than  those  that  could  be  obtained  in a  comparable  arm's  length
transaction  with a Person that is not such an Affiliate  and (iii) with respect
to such business,  transaction or series of related transactions that has a fair
market  value or  involves  aggregate  payments  equal to, or in excess  of, $10

such business,  transaction or series of transactions  complies with clauses (i)
and (ii) above.

shall not  permit  any of its  Restricted  Subsidiaries  or any  Eligible  Joint
Venture  to,  grant  a Lien  on the  Property  of the  Company,  its  Restricted

ratably  secured  except for (i) any such Debt secured by Liens  existing on the
Property of any entity at the time such Property is acquired by the Company, any
of its Restricted Subsidiaries or any Eligible Joint Venture, whether by merger,

comparable financings or comparable transactions in the applicable jurisdiction,
(iv) Liens existing on the Issue Date of the  Securities,  (v) Liens incurred to

         SECTION 1013. Purchase of Securities Upon a Change of Control. (a) Upon
the  occurrence  of a Change of Control,  each Holder of the  Securities of each
series shall have the right to require that the Company repurchase such Holder's
Securities  of such  series  at a  purchase  price in cash  equal to 101% of the
principal thereof on the date of purchase plus accrued interest,  if any, to the
date of purchase.

         (b) Within 30 days  following  a Change of Control,  the Company  shall
mail a notice to each Holder of the  Securities  of each series,  with a copy to
the  Trustee,  stating (1) that a Change of Control has  occurred  and that such
Holder has the right to require the Company to purchase such Holder's Securities
at the  purchase  price  described  in Section  1013(a)  (the "Change of Control
Offer"),  (2) the  circumstances  and relevant  facts  regarding  such Change of
Control (including information with respect to pro forma historical income, cash
flow and capitalization after giving effect to such Change of Control),  (3) the
purchase  date (which  shall be not earlier  than 30 days nor later than 60 days
from the date such notice is mailed)  (the "Change of Control  Purchase  Date"),
(4) that  interest  on any such  Security  shall  continue  to  accrue,  (5) any
Security  properly  tendered pursuant to the Change of Control Offer shall cease
to  accrue  interest  after  the  Change  of  Control  Purchase  Date  (assuming
sufficient moneys for the purchase thereof are deposited with the Trustee),  (6)
that Holders electing to have a Security of any series  purchased  pursuant to a
Change of Control  Offer  shall be required to  surrender  the  Security of such
series,  with the form  entitled  "Option  of Holder To Elect  Purchase"  on the
reverse of the Security completed,  to the paying agent at the 


                                       97
<PAGE>


address  specified  in the notice  prior to the close of  business  on the fifth
Business  Day prior to the Change of Control  Purchase  Date,  (7) that a Holder
shall be  entitled  to  withdraw  such  Holder's  election  if the Paying  Agent
receives,  not later than the close of  business on the third  Business  Day (or
such shorter  periods as may be required by applicable law) preceding the Change
of Control Purchase Date, a telegram,  telex,  facsimile  transmission or letter
setting forth the name of the Holder, the principal amount of Securities of such
series the Holder  delivered for purchase,  and a statement  that such Holder is
withdrawing  his election to have such  Securities of such series  purchased and
(8) that Holders  that elect to have their  Securities  of any series  purchased
only in part shall be issued new Securities  having a principal  amount equal to
the  portion of the  Securities  of the  series  that were  surrendered  but not
tendered and purchased.

         On the Change of Control  Purchase  Date,  the Company shall (i) accept
for payment all Securities of any series or portions thereof  tendered  pursuant
to the Change of Control Offer,  (ii) deposit with the Trustee money  sufficient
to pay the purchase price of all  Securities of such series or portions  thereof
so tendered  for  purchase  and (iii)  deliver or cause to be  delivered  to the
Trustee  the  Securities  of such  series  properly  tendered  together  with an
Officers'  Certificate  identifying  the  Securities  of such series or portions
thereof  tendered to the Company for purchase.  The Trustee shall promptly mail,
to the Holders of the Securities of such series properly tendered and purchased,
payment in an amount equal to the purchase price, and promptly  authenticate and
mail to each Holder a new Security of the same series having a principal  amount
equal to any  portion  of such  Holder's  Securities  of such  series  that were
surrendered but not tendered and purchased.  The Company shall publicly announce
the results of the Change of Control  Offer on or as soon as  practicable  after
the Change of Control Purchase Date.

         If the Company is prohibited  by applicable  law from making the Change
of Control Offer or purchasing Securities of any series thereunder,  the Company
need not make a Change of Control  Offer  pursuant to this  Section  1013 for so
long as such prohibition is in effect.

         The  Company  shall  comply with all  applicable  tender  offer  rules,
including,  without limitation, Rule 14e-1 under the Exchange Act, in connection
with a Change of Control Offer.

         SECTION 1014.  Limitation  on Dividends and Other Payment  Restrictions
Affecting  Subsidiaries.  The Company shall not, and shall not permit any of its
Restricted  Subsidiaries  or any Eligible  Joint  Venture to, create or cause to
become, or as a 


                                       98
<PAGE>


result of the acquisition of any Person or Property, or upon any Person becoming
a Restricted Subsidiary or an Eligible Joint Venture, remain subject to, any
consensual encumbrance or consensual restriction of any kind on the ability of
any Restricted Subsidiary or any Eligible Joint Venture to (a) pay dividends or
make any other distributions permitted by applicable law on any Capital Stock of
such Restricted Subsidiary or such Eligible Joint Venture owned by the Company,
any other Restricted Subsidiary or any other Eligible Joint Venture, (b) make
payments in respect of any Debt owed to the Company, any other Restricted
Subsidiary of the Company or any Eligible Joint Venture, (c) make loans or
advances to the Company or to any other Restricted Subsidiary of the Company or
any other Eligible Joint Venture that is directly or indirectly owned by such
Restricted Subsidiary or such Eligible Joint Venture or (d) transfer any of its
Property to the Company or to any other Restricted Subsidiary or any other
Eligible Joint Venture that directly or indirectly owns or is owned by such
Restricted Subsidiary or such Eligible Joint Venture, other than those
encumbrances and restrictions created or existing (i) on the Issue Date of the
Securities, (ii) pursuant to this Indenture, (iii) in connection with the
Incurrence of any Debt permitted under the provisions described in clause (iii)
of Section 1009(b), provided that, in the case of Debt owed to Persons other
than the Company, its Restricted Subsidiaries and any Eligible Joint Venture,
the President or the Chief Financial Officer of the Company determines in good
faith, as evidenced by an Officers' Certificate, that such encumbrances or
restrictions are required to effect such financing and are not materially more
restrictive, taken as a whole, on the ability of the applicable Restricted
Subsidiary or the applicable Eligible Joint Venture to make the payments,
distributions, loans, advances or transfers referred to in clauses (a) through
(d) of this Section 1014 than encumbrances and restrictions, taken as a whole,
customarily accepted (or, in the absence of any industry custom, reasonably
acceptable) in comparable financings or comparable transactions in the
applicable jurisdiction, (iv) in connection with the execution and delivery of
an electric power or thermal energy purchase contract, or other contract related
to the output or product of, or services rendered by one or more Permitted
Facilities to which such Restricted Subsidiary or such Eligible Joint Venture is
a supplying party or other contracts with customers, suppliers and contractors
to which such Restricted Subsidiary or such Eligible Joint Venture is a party
and where such Restricted Subsidiary or such Eligible Joint Venture is engaged,
directly or indirectly, in the development, design, engineering, procurement,
construction, acquisition, ownership, management or operation of one or more of
such Permitted Facilities, provided that the President or the Chief Financial
Officer of the Company determines in good faith, as evidenced by an Officers'
Certificate, that such encumbrances or


                                       99
<PAGE>


restrictions  are required to effect such contracts and are not materially  more
restrictive,  taken as a whole,  on the  ability  of the  applicable  Restricted
Subsidiary  or the  applicable  Eligible  Joint  Venture  to make the  payments,
distributions,  loans,  advances or transfers referred to in clauses (a) through
(d) of this Section 1014 than encumbrances and  restrictions,  taken as a whole,
customarily  accepted  (or, in the absence of any  industry  custom,  reasonably
acceptable)  in  comparable   financings  or  comparable   transactions  in  the
applicable jurisdiction, (v) in connection with any Acquired Debt, provided that
such encumbrance or restriction was not incurred in contemplation of such Person
becoming a  Restricted  Subsidiary  or an Eligible  Joint  Venture and  provided
further  that  such  encumbrance  or  restriction  does not  extend to any other
Property  of such  Person at the time it became a  Restricted  Subsidiary  or an
Eligible  Joint  Venture,  (vi) in  connection  with the  Incurrence of any Debt
permitted  under clause (iv) of Section  1009(b),  provided that, in the case of
Debt owed to Persons other than the Company and its Restricted Subsidiaries, the
President  or the Chief  Financial  Officer of the  Company  determines  in good
faith,  as evidenced  by an Officers'  Certificate,  that such  encumbrances  or
restrictions  taken as a whole  are not  materially  more  restrictive  than the
encumbrances  and  restrictions  applicable  to the  Debt  and/or  equity  being
exchanged or refinanced,  (vii) customary non-assignment provisions in leases or
other contracts  entered into in the ordinary course of business of the Company,
any Restricted Subsidiary or any Eligible Joint Venture, (viii) any restrictions
imposed pursuant to an agreement entered into for the sale or disposition of all
or  substantially  all  of the  Capital  Stock  or  Property  of any  Restricted
Subsidiary  or Joint  Venture  that apply  pending  the  closing of such sale or
disposition,  (ix) in connection  with Liens on the Property of such  Restricted
Subsidiary or such Eligible Joint Venture that are permitted by Section 1012 but
only with respect to transfers  referred to in clause (d) of this Section  1014,
(x) in connection with the Incurrence of any Debt permitted under clause (ii) of
Section  1009(b) or (xi) in  connection  with the  Incurrence  of any  Permitted
Facilities Debt permitted under clause (viii) of Section 1009(b),  provided that
any  such   encumbrance  or  restriction   relates  only  to  those   Restricted
Subsidiaries or Eligible Joint Ventures having a direct or indirect  interest in
the Permitted  Facilities in respect of which such Permitted Facilities Debt was
Incurred.

         SECTION 1015. Limitation on Dispositions. (a) Subject to the provisions
of Article  Eight,  the  Company  shall not make and shall not permit any of its
Restricted  Subsidiaries  or any  Eligible  Joint  Venture  to make,  any  Asset
Disposition  unless (i) the Company,  the Restricted  Subsidiary or the Eligible
Joint Venture,  as the case may be, receives  consideration  at the time 


                                       100
<PAGE>


of each such Asset  Disposition  at least equal to the fair market  value of the
Property or securities  sold or otherwise  disposed of (to be determined in good
faith by the Chief Financial Officer, as evidenced by an Officers'  Certificate,
or, if more than $30 million, by the Board of Directors, as evidenced by a Board
resolution), (ii) at least 85% of such consideration is received in cash or Cash
Equivalents or, if less than 85%, the remainder of such  consideration  consists
of Property  related to the  business of the Company as  described  in the first
sentence of Section 1021, and (iii) unless otherwise required under the terms of
Senior Debt,  at the  Company's  election,  the Net Cash Proceeds are either (A)
invested in the business of the Company,  any of its Restricted  Subsidiaries or
any  Eligible  Joint  Venture or (B)  applied to the  payment of any Debt of the
Company or of any of its Restricted  Subsidiaries  or any Eligible Joint Venture
(or as otherwise required under the terms of such Debt),  provided that, no such
payment of Debt (x) under  Permitted  Working  Capital  Facilities  or any other
revolving  credit agreement shall count for this purpose unless the related loan
commitment,  standby  facility  or the like shall be  permanently  reduced by an
amount equal to the  principal  amount so repaid and (y) owed to the Company,  a
Restricted  Subsidiary thereof or an Eligible Joint Venture shall count for this
purpose,  provided further that such investment or such payment, as the case may
be,  must be made  within  365  days  from the  later of the date of such  Asset
Disposition or the receipt by the Company,  such  Restricted  Subsidiary or such
Eligible Joint Venture of the Net Cash Proceeds  related  thereto.  Any Net Cash
Proceeds from Asset  Dispositions that are not applied as provided in clause (A)
or (B) of the preceding  sentence shall  constitute  "Excess  Proceeds."  Excess
Proceeds  shall be applied,  as  described  below,  to make an offer (an "Excess
Proceeds Offer") to purchase  Securities of any series at a purchase price equal
to 100% of the principal thereof,  plus accrued interest, if any, to the date of
purchase.

         (b) Notwithstanding the provisions of Section 1015(a), the Company, its
Restricted  Subsidiaries and the Eligible Joint Ventures may exchange with other
Persons (i) Property  that  constitutes  a Restricted  Subsidiary or an Eligible
Joint  Venture for  Property  that  constitutes  a Restricted  Subsidiary  or an
Eligible Joint Venture,  (ii) Property that constitutes a Restricted  Subsidiary
or an Eligible  Joint Venture for Property that does not constitute a Restricted
Subsidiary or an Eligible Joint Venture, (iii) Property that does not constitute
a Restricted  Subsidiary or an Eligible Joint Venture for Property that does not
constitute  a  Restricted  Subsidiary  or an  Eligible  Joint  Venture  and (iv)
Property that does not  constitute a Restricted  Subsidiary or an Eligible Joint
Venture for Property  that  constitutes  a Restricted  Subsidiary or an Eligible
Joint Venture,  provided that in each case the fair market value of the 


                                       101
<PAGE>

Property  received is at least equal to the fair  market  value of the  Property
exchanged  as  determined  in good  faith by the  Chief  Financial  Officer,  as
evidenced by an  Officers'  Certificate,  or, if more than $25  million,  by the
Board of  Directors,  as  evidenced  by a Board  resolution,  provided  that the
Investment in the Property  received in the exchanges  described in clauses (ii)
and  (iii)  of  the  prior   sentence   shall  be  subject   to  Section   1010.
Notwithstanding  anything in the foregoing to the contrary, the Company may not,
and shall not permit any of its  Restricted  Subsidiaries  or any Eligible Joint
Venture to, make an Asset  Disposition  of any of their interest in, or Property
of, any of the three geothermal facilities located together at the Naval Weapons
Center at China Lake,  California,  sometimes referred to as the "Coso Project,"
other than for consideration consisting solely of cash.

         (c) To the  extent  that  any or all of the Net  Cash  Proceeds  of any
Foreign Asset  Disposition are prohibited from (or delayed in) being repatriated
to the  United  States by  applicable  local law,  the  portion of such Net Cash
Proceeds  so affected  shall not be required to be applied at the time  provided
above but may be retained by any  Restricted  Subsidiary  or any Eligible  Joint
Venture so long, but only so long, as the  applicable  local law does not permit
(or delays)  repatriation  to the United  States.  If such Net Cash Proceeds are
transferred  by  the  Restricted  Subsidiary  or  Eligible  Joint  Venture  that
conducted  the Foreign Asset  Disposition  to another  Restricted  Subsidiary or
Eligible  Joint  Venture,  the  Restricted  Subsidiary or Eligible Joint Venture
receiving such Net Cash Proceeds must not be directly or indirectly obligated on
any Debt owed to any Person  other than the Company.  The Company  shall take or
cause such  Restricted  Subsidiary  or such  Eligible  Joint Venture to take all
actions  required  by the  applicable  local  law to  permit  such  repatriation
promptly.  Once repatriation of any of such Net Cash Proceeds is permitted under
the applicable  local law,  repatriation  shall be effected  immediately and the
repatriated  Net Cash Proceeds  shall be applied in the manner set forth in this
Section  1015(c) as if such Asset  Disposition  had occurred on the date of such
repatriation.  In addition,  if the Chief Financial Officer determines,  in good
faith, as evidenced by an Officers' Certificate, that repatriation of any or all
of the Net Cash Proceeds of any Foreign Asset  Disposition would have a material
adverse tax consequence to the Company, the Net Cash Proceeds so affected may be
retained outside of the United States by the applicable Restricted Subsidiary or
the applicable  Eligible Joint Venture for so long as such material  adverse tax
consequence  would continue.  Notwithstanding  the foregoing  provisions of this
paragraph to the  contrary,  if  applicable  local law prohibits (or delays) the
repatriation of Net Cash Proceeds of a Foreign Asset  Disposition but such local
law does not 


                                       102
<PAGE>

prohibit  the  application  of such  Net Cash  Proceeds  pursuant  to the  first
sentence of this Section  1015(a),  the Company may apply such Net Cash Proceeds
pursuant to such provision.

         (d) If the  Securities  tendered  pursuant to an Excess  Proceeds Offer
have an aggregate purchase price that is less than the Excess Proceeds available
for the purchase of the  Securities,  the Company may use the  remaining  Excess
Proceeds for general corporate purposes without regard to the provisions of this
Section  1015(d).  The Company shall not be required to make an Excess  Proceeds
Offer pursuant to this Section 1015 if the Excess  Proceeds  available  therefor
are less than $10  million,  provided  that the lesser  amounts  of such  Excess
Proceeds shall be carried  forward and cumulated for each 36  consecutive  month
period for purposes of determining  whether an Excess Proceeds Offer is required
with respect to any Excess Proceeds of any subsequent  Asset  Dispositions.  Any
such lesser  amounts so carried  forward and cumulated need not be segregated or
reserved and may be used for general corporate purposes,  provided that such use
shall not reduce the amount of cumulated  Excess Proceeds or relieve the Company
of its  obligation  hereunder  to make an Excess  Proceeds  Offer  with  respect
thereto.

         (e) The Company shall make an Excess  Proceeds Offer by mailing to each
Holder,  with a copy to the Trustee,  within 30 days after the receipt of Excess
Proceeds  that cause the  cumulated  Excess  Proceeds to exceed $10  million,  a
written  notice that shall  specify the purchase  date,  which shall not be less
than 30 days nor more than 60 days after the date of such  notice  (the  "Excess
Proceeds Purchase Date"), that shall contain certain information  concerning the
business of the Company that the Company believes in good faith shall enable the
Holders  to make  an  informed  decision  and  that  shall  contain  information
concerning the procedures  applicable to the Excess  Proceeds Offer  (including,
without limitation, the right of withdrawal) and the effect of such offer on the
Securities tendered. Holders that elect to have their Securities purchased shall
be required to surrender such  Securities at least one Business Day prior to the
Excess Proceeds Purchase Date. If at the expiration of the Excess Proceeds Offer
period the aggregate  purchase  price of the  Securities of the series  properly
tendered by Holders  pursuant to the Excess Proceeds Offer exceeds the amount of
such Excess Proceeds, the Securities of such series or portions of Securities to
be accepted for purchase  shall be selected by the Trustee in such manner as the
Trustee deems to be fair and appropriate in the circumstances.

         On the Excess Proceeds  Purchase Date, the Company shall (i) accept for
payment  on a pro rata  basis  Securities  of any  series  or  portions  thereof
tendered  pursuant to the Excess  


                                       103
<PAGE>


Proceeds  Offer,  (ii)  deposit  with the  Paying  Agent  money  in  immediately
available  funds  sufficient  to pay the  aggregate  purchase  price  of all the
Securities  of such series or portions  thereof so accepted and (iii) deliver to
the  Trustee  Securities  so accepted  together  with an  Officers'  Certificate
stating  the  Securities  of such  series or  portions  thereof  tendered to the
Company. The Paying Agent shall promptly mail to the Holders of each Security so
accepted  payment in an amount equal to the aggregate  purchase  price,  and the
Trustee shall promptly  authenticate and mail to the Holders of each Security so
accepted  payment in an amount  equal to the  purchase  price  thereof,  and the
Trustee shall promptly  authenticate  and mail to such Holders new Securities of
the same  series  equal in  principal  amount  to any  portion  of the  Security
surrendered that was not purchased. The Company shall make a public announcement
of the results of the Excess  Proceeds  Offer as soon as  practicable  after the
Excess  Proceeds  Purchase  Date.  For the  purposes of this Section  1015,  the
Trustee shall act as the Paying Agent.

         If the Company is prohibited  by applicable  law from making the Excess
Proceeds Offer or purchasing  Securities of any series  thereunder,  the Company
need not make an Excess Proceeds Offer pursuant to this Section 1015 for so long
as such prohibition is in effect.

         The  Company  shall  comply with all  applicable  tender  offer  rules,
including,  without limitation, Rule 14e-1 under the Exchange Act, in connection
with an Excess Proceeds Offer.

         SECTION 1016. Limitation on Certain Sale-Leasebacks.  The Company shall
not,  and shall not permit any of its  Restricted  Subsidiaries  or any Eligible
Joint  Venture to,  Incur or  otherwise  become  obligated  with  respect to any
sale-leaseback (other than a sale-leaseback with respect to a Permitted Facility
that is Non-Recourse)  unless,  (i) (a) if effected by the Company,  the Company
would be  permitted  to Incur  such  obligation  under  Section  1008 or, (b) if
effected  by  a  Restricted  Subsidiary  or  an  Eligible  Joint  Venture,  such
Restricted Subsidiary or such Eligible Joint Venture would be permitted to Incur
such obligation under Section 1009(b),  assuming for the purpose of this Section
1016  and  Section  1008  and  1009  that  (x) the  obligation  created  by such
sale-leaseback  is a Capitalized  Lease and (y) the Capitalized Lease Obligation
with respect thereto is the Attributable Value thereof,  (ii) the Company,  such

principal amount at Stated Maturity of the Outstanding Securities of such series
shall, by Act of such Holders,  either waive such compliance in such instance or
generally waive  compliance with such covenant or condition,  but no such waiver
shall  extend to or affect such  covenant or  condition  except to the extent so
expressly waived, and, until such waiver shall become effective, the obligations
of the Company and the duties of the Trustee in respect of any such  covenant or
condition shall remain in full force and effect.

         SECTION 1021.  Limitation  on Business.  The Company  shall,  and shall
cause its  Restricted  Subsidiaries  and the Eligible  Joint Ventures to, engage

directly  related to the business of the Company as  described in the  preceding
sentence (collectively, the "Ineligible Investments") other than as a part of an
Investment  or an  acquisition  of Property that is  predominantly  and directly
related to the business of the Company as described  above, and if the aggregate
fair market value of such  Ineligible  Investments in the aggregate  exceeds 20%
(the "Percentage Limit") of the total assets of the Company and its consolidated
Restricted Subsidiaries (as determined in accordance with GAAP) as determined in
good  faith  by the  Chief  Financial  Officer,  as  evidenced  by an  Officers'
Certificate,  the Company,  its Restricted  Subsidiaries  and the Eligible Joint
Ventures must cease acquiring any additional Ineligible  Investments and, within
18 months of the  acquisition  that caused the  Ineligible  Assets to exceed the
Percentage  Limit,  must  return  to  compliance  with the  Percentage  Limit by
disposing 


                                       107
<PAGE>


of  Ineligible  Assets or otherwise,  provided that such 18-month  period may be
extended up to an additional six months if, despite the Company's active efforts
during such  18-month  period to dispose of such  Ineligible  Investments  or to
otherwise come into compliance with such Percentage Limit, the Company is unable
to do so  because  of  regulatory  restrictions  or  delays  or  adverse  market
conditions.


                                 ARTICLE ELEVEN

                            REDEMPTION OF SECURITIES

         SECTION 1101. Right of Redemption.  The Securities of any series may be
redeemed at the election of the Company, in the amounts, at such time and at the
Redemption Prices specified in the form of Security of such series  hereinbefore
set forth  (together  with any  applicable  accrued  and unpaid  interest to the
Redemption Date) and subject to the conditions specified in the form of Security
of such series hereinafter set forth.

         SECTION 1102. Applicability of Article. Redemption of Securities of any
series at the election of the Company,  as permitted by this  Indenture  and the
provisions of the  Securities of such series,  shall be made in accordance  with
such provisions and this Article Eleven.

         SECTION 1103.  Election to Redeem;  Notice to Trustee.  The election of
the Company to redeem any Securities pursuant to Section 1101 shall be evidenced
by or pursuant to a Board Resolution.  In case of any redemption at the election
of the Company  pursuant to Section 1101 of less than all the  Securities of any
series,  the Company shall,  at least 60 days prior to the Redemption Date fixed
by the Company  (unless a shorter notice shall be  satisfactory to the Trustee),
notify  the  Trustee  of such  Redemption  Date and of the  principal  amount of
Securities of such series to be redeemed.

         SECTION 1104.  Selection by Trustee of  Securities  to Be Redeemed.  If
less than all the Outstanding  Securities of any series are to be redeemed,  the
Securities  or portions  of  Securities  to be  redeemed  or  accepted  shall be
selected  by the  Trustee  pro rata or  otherwise  in such manner as the Trustee
deems to be fair and appropriate in the circumstances, provided that the Trustee
shall  redeem  Securities  of that  series to be  redeemed  only in the  minimum
authorized denominations of Securities of such series.


                                       108
<PAGE>


         The  Trustee  shall  promptly  notify  the  Company  and each  Security
Registrar in writing of the Securities  selected for redemption and, in the case
of any Securities selected for partial redemption,  the principal amount thereof
to be redeemed.

         For all purposes of this  Indenture and or the  Securities,  unless the
context  otherwise  requires,  all  provisions  relating  to the  redemption  of
Securities  shall  relate,  in the  case  of any  Securities  redeemed  or to be
redeemed only in part, to the portion of the principal amount of such Securities
that has been or is to be redeemed.

         SECTION 1105. Notice of Redemption. Notice of redemption shall be given
as  provided  in Section 106 not less than 30 nor more than 60 days prior to the
Redemption Date, to each Holder of Securities to be redeemed.

         All notices of redemption shall state:

         (1) the Redemption Date,

         (2) the Redemption Price,

         (3) if less than all the Outstanding Securities of any series are to be
    redeemed,  the identification  (and, in the case of partial redemption,  the
    principal  amounts) of the particular  Securities to be redeemed,  including
    CUSIP Numbers,

         (4) that on the Redemption  Date the Redemption  Price shall become due
    and payable  upon each such  Security to be  redeemed  and that,  unless the
    Company  shall  default  in the  payment  of the  Redemption  Price  and any
    applicable  accrued  interest,  interest thereon will cease to accrue on and
    after said date, and

         (5) the name of the  Paying  Agent or  Agents  and the  place or places
    where such  Securities are to be  surrendered  for payment of the Redemption
    Price.

         Notice of  redemption  of  Securities to be redeemed at the election of
the Company shall be given by the Company or, at the Company's  request,  by the
Trustee in the name and at the expense of the Company and shall be irrevocable.

         SECTION 1106.  Deposit of  Redemption  Price.  Prior to any  Redemption
Date,  the Company  shall deposit with the Trustee or with a Paying Agent (or if
the Company is acting as its own Paying  Agent,  segregate  and hold in trust as
provided in Section 1003) an amount of money  sufficient  to pay the  Redemption
Price of, and (except if the Redemption Date shall be an Interest  


                                       109
<PAGE>


Payment Date) any applicable  accrued and unpaid interest on, all the Securities
of the series that are to be redeemed on that date.

         SECTION  1107.   Securities  Payable  on  Redemption  Date.  Notice  of
redemption  having been given as  aforesaid,  the  Securities  so to be redeemed
shall, on the Redemption  Date,  become due and payable at the Redemption  Price
therein  specified,  and from and after  such date  (unless  the  Company  shall
default in the payment of the Redemption  Price and any  applicable  accrued and
unpaid interest) such Securities shall not bear interest.  Upon surrender of any
such Security for redemption in accordance with said notice, such Security shall
be paid by the Company at the  Redemption  Price,  together with any  applicable
accrued and unpaid interest to the Redemption Date;  provided that  installments
of interest whose Stated Maturity is on or prior to the Redemption Date shall be
payable  to  the  Holders  of  such  Securities,  or  one  or  more  Predecessor
Securities,  registered as such at the close of business on the relevant  Record
Dates according to their terms and the provisions of Section 310.

         If any Security  called for redemption in accordance  with the election
of the Company made pursuant to Section 1101 shall not be so paid upon surrender
thereof for redemption,  the unpaid Redemption Price thereof shall,  until paid,
bear interest  from the  Redemption  Date at the rate or manner  provided by the
Security.

         SECTION 1108.  Securities  Redeemed in Part. Any Security that is to be
redeemed only in part shall be surrendered at an office or agency of the Company
designated  for that purpose  pursuant to Section 1002 (with,  if the Company or
the Trustee so requires, due endorsement by, or a written instrument of transfer
in form satisfactory to the Company and the Trustee duly executed by, the Holder
thereof or his  attorney  duly  authorized  in writing),  and the Company  shall
execute,  and the Trustee shall  authenticate  and deliver to the Holder of such
Security  without  service  charge,  a new  Security or  Securities  of the same
series, of any authorized denomination as requested by such Holder, in aggregate
principal  amount  equal to and in exchange  for the  unredeemed  portion of the
principal amount of the Security so surrendered.


                                 ARTICLE TWELVE

                       DEFEASANCE AND COVENANT DEFEASANCE

         SECTION  1201.  Company's  Option  to  Effect  Defeasance  or  Covenant
Defeasance.  The Company may elect,  at its option at any 


                                       110
<PAGE>


time, to have Section 1202 or Section 1203 applied to the Outstanding Securities
of or within any series  (as a whole and not in part) upon  compliance  with the
conditions  set forth below in this Article  Twelve.  Any such election shall be
evidenced by a Board Resolution.

         SECTION 1202. Defeasance and Discharge.  Upon the Company's exercise of
its option to have this Section 1202 applied to the Outstanding Securities of or
within a series  (as a whole and not in part),  the  Company  shall be deemed to
have been  discharged  from its  obligations  with respect to such Securities as
provided in this  Section  1202 on and after the 123rd day after the  conditions
set forth in Section 1204 are satisfied  (hereinafter  called  "Defeasance") (or
immediately  if an Opinion of Counsel is  delivered  to the effect  described in
clause  (C) (y) of  paragraph  (2) of  Section  1204).  For this  purpose,  such
Defeasance  means that the Company  shall be deemed to have paid and  discharged
the entire indebtedness represented by such Securities and to have satisfied all
its other  obligations  under such Securities and this Indenture insofar as such
Securities are concerned (and the Trustee, at the expense of the Company,  shall
execute proper  instruments  acknowledging  the same),  subject to the following
which shall survive until otherwise terminated or discharged hereunder:  (1) the
rights of Holders of such  Securities  to  receive,  solely  from the trust fund
described in Section 1204 and as more fully set forth in such Section,  payments
in respect of the  principal of and any premium and interest on such  Securities
when  payments  are due,  (2) the  Company's  obligations  with  respect to such
Securities  under Sections 307, 308, 309, 1002, 1003 and 1004 (only with respect
to the corporate existence and rights of the Company),  (3) the rights,  powers,
trusts,  duties and immunities of the Trustee under this Indenture,  (4) Article
Eleven and (5) this  Article  Twelve.  Subject to  compliance  with this Article
Twelve, the Company may exercise its option to have this Section 1202 applied to
the  Outstanding  Securities  (as a whole and not in part)  notwithstanding  the
prior exercise of its option to have Section 1203 applied to such Securities.

         SECTION 1203. Covenant  Defeasance.  Upon the Company's exercise of its
option to have this Section applied to the Outstanding Securities of or within a
series  (as  a  whole  and  not  in  part),  (i)  the  Company,  its  Restricted
Subsidiaries  and its  Eligible  Joint  Ventures  shall  be  released  from  its
obligations  under Section  801(iii),  Sections  1005 through  1018,  inclusive,
Section 1021, and any covenant  provided pursuant to Section 901(2) and (ii) the
occurrence  of any event  specified  in Section  501(1)  (solely with respect to
Offers to  Purchase),  Section  501(3),  Section  501(4) (with respect to any of
Section  801(iii) and Sections 1005 through 1018,  inclusive,  Section 1021, and
any 


                                       111
<PAGE>


such covenants  provided pursuant to Section 901(2)),  Section 501(5) or Section
501(6) shall be deemed not to be or result in an Event of Default,  in each case
with  respect to such  Securities  as provided in this  Section on and after the
date the conditions set forth in Section 1204 are satisfied  (hereinafter called
"Covenant  Defeasance").  For this purpose, such Covenant Defeasance means that,
with respect to such  Securities,  the Company may omit to comply with and shall
have no liability in respect of any term,  condition or limitation  set forth in
any such  specified  Section (to the extent so specified in the case of Sections
501(1) and 501(4)),  whether  directly or  indirectly by reason of any reference
elsewhere  herein to any such Section or by reason of any  reference in any such
Section  to any  other  provision  herein  or in any  other  document;  but  the
remainder of this Indenture and such Securities shall be unaffected thereby.

         SECTION 1204.  Conditions to  Defeasance  or Covenant  Defeasance.  The
following  shall be the conditions to the application of Section 1202 or Section
1203 to the Outstanding Securities of or within a series:

         (1) The  Company  shall  irrevocably  have  deposited  or  caused to be
    deposited   with  the  Trustee  (or  another   trustee  that  satisfies  the
    requirements  contemplated  by  Section  609 and  agrees to comply  with the
    provisions of this Article applicable to it) as trust funds in trust for the
    purpose of making the following payments,  specifically  pledged as security
    for, and dedicated solely to the benefits of the Holders of such Securities,
    (A) money in an amount, or (B) U.S. Government  Obligations that through the
    scheduled payment of principal and interest in respect thereof in accordance
    with their terms shall  provide,  not later than one day before the due date
    of any payment,  money in an amount, or (C) a combination  thereof,  in each
    case  sufficient,  in  the  opinion  of  a  nationally  recognized  firm  of
    independent public accountants  expressed in a written certification thereof
    delivered to the Trustee,  to pay and discharge,  and which shall be applied
    by the Trustee (or any such other qualifying  trustee) to pay and discharge,
    the principal of, premium if any and any installment of accrued  interest on
    such  Securities  on the  respective  Stated  Maturities  thereof or, if the
    Company makes arrangements satisfactory to the Trustee for the redemption of
    the Securities  prior to their Stated  Maturity,  on any earlier  Redemption
    Date, in accordance with the terms of this Indenture and such Securities.

         (2) In the  event of an  election  to have  Section  1202  apply to the
    Outstanding Securities,  the Company shall have delivered to the Trustee (A)
    either  (X) an Opinion of  


                                       112
<PAGE>


Counsel to the effect that Holders shall not recognize income,  gain or loss for
federal  income  tax  purposes  as a  result  of such  deposit,  defeasance  and
discharge  and shall be subject to federal  income tax on the same amount and in
the same  manner  and at the same  times  as  would  have  been the case if such
deposit,  defeasance  and discharge had not occurred and the Company had paid or
redeemed such Securities on the applicable dates,  which Opinion of Counsel must
be based upon a ruling of the Internal  Revenue  Service to the same effect or a
change in  applicable  federal  income tax law or related  Treasury  regulations
after the date of the  Indenture or (y) a ruling  directed to the Trustee or the
Company  received  from the Internal  Revenue  Service to the same effect as the
aforementioned  Opinion of Counsel, (B) an Opinion of Counsel to the effect that
the creation of the defeasance trust does not violate the Investment Company Act
of 1940 and (C) an Opinion of  Counsel to the effect  that  either (x) after the
passage of 123 days  following the deposit,  the trust fund shall not be subject
to the effect of Section 547 or 548 of the U.S. Bankruptcy Code or Section 15 of
the New York Debtor and Creditor Law or (y) based upon existing  precedents,  if
the manner were properly briefed, a court should hold that the deposit of moneys
and/or U.S.  Government  Obligations  as provided in Section  1204(1)  would not
constitute a preference voidable under Section 547 or 548 of the U.S. Bankruptcy
Code or Section 15 of the New York Debtor and Creditor Law.

         (3) In the  event of an  election  to have  Section  1203  apply to the
    Outstanding Securities,  the Company shall have delivered to the Trustee (i)
    an Opinion of Counsel  to the effect  that the  Holders of such  Outstanding
    Securities shall not recognize  income,  gain or loss for Federal income tax
    purposes as a result of the deposit and Covenant  Defeasance  to be effected
    with respect to such  Securities  and shall be subject to Federal income tax
    on the same amount, in the same manner and at the same times as would be the
    case if such  deposit  and  Covenant  Defeasance  were not to occur  and the
    Company had paid or redeemed such Securities on the applicable  dates,  (ii)
    an Opinion of Counsel to the  effect  that the  creation  of the  defeasance
    trust  does not  violate  the  Investment  Company  Act of 1940 and (iii) an
    Opinion of Counsel to the effect  that  either (x) after the  passage of 123
    days  following  the  deposit,  the trust  fund  shall not be subject to the
    effect of Section  547 or 548 of the U.S.  Bankruptcy  Code or Section 15 of
    the New York Debtor and Creditor Law or (y) based upon existing  precedents,
    if the manner were properly briefed, a court should hold that the deposit of
    moneys and/or U.S.  Government  Obligations  as provided in Section  1204(1)
    would not  constitute a 


                                       113
<PAGE>


preference  voidable  under  Section 547 or 548 of the U.S.  Bankruptcy  Code or
Section 15 of the New York Debtor and Creditor Law.

         (4)  Immediately  after  giving  effect to such  deposit on a pro forma
    basis,  no  Default  or Event of Default  with  respect  to the  Outstanding
    Securities shall have occurred and be continuing at the time of such deposit
    or (unless an Opinion of Counsel is  delivered  to the effect  described  in
    Section  1204(2)(C)(y) or  1204(3)(iii)(y))  during the period ending on the
    123rd day after the date of such deposit.

         (5) Such Defeasance or Covenant  Defeasance shall not cause the Trustee
    to have a conflicting interest within the meaning of the Trust Indenture Act
    (assuming all Securities are in default within the meaning of such Act).

         (6) Such Defeasance or Covenant Defeasance shall not result in a breach
    or violation  of, or  constitute  a default  under,  any other  agreement or
    instrument to which the Company is a party or by which it is bound.

         (7) Such  Defeasance  or  Covenant  Defeasance  shall not result in the
    trust arising from such deposit  constituting  an investment  company within
    the meaning of the Investment  Company Act of 1940, as amended,  unless such
    trust  shall be  registered  under  such  Act or  exempt  from  registration
    thereunder.

         (8) The  Company  shall have  delivered  to the  Trustee  an  Officers'
    Certificate  and an Opinion of Counsel,  each  stating  that all  conditions
    precedent with respect to such  Defeasance or Covenant  Defeasance have been
    complied with.

         (9) If the Securities are listed on a national securities exchange, the
    Company  shall have  delivered  to the  Trustee an Opinion of Counsel to the
    effect  that the  Securities  shall  not be  delisted  as a  result  of such
    deposit, defeasance and discharge.

         SECTION 1205.  Deposited  Money and U.S.  Government  Obligations to Be
Held in Trust;  Miscellaneous Provisions.  Subject to the provisions of the last
paragraph of Section 1003, all money and U.S. Government  Obligations (including
the proceeds  thereof)  deposited with the Trustee or other  qualifying  trustee
(solely for purposes of this Section 1205 and Section 1206,  the Trustee and any
such other trustee are referred to  collectively  as the "Trustee")  pursuant to
Section 1204 or otherwise in respect of the Outstanding Securities of any series
shall be held in trust  and  applied  by the  Trustee,  in  accordance  with the


                                       114
<PAGE>


provisions  of such  Securities  and  this  Indenture,  to the  payment,  either
directly or through any such Paying Agent (other than the Company  acting as its
own  Paying  Agent)  as the  Trustee  may  determine,  to the  Holders  of  such
Securities,  of all sums due and to become due  thereon in respect of  principal
and any premium and interest,  but money so held in trust need not be segregated
from other funds except to the extent required by law.

         The Company shall pay and indemnify the Trustee against any tax, fee or
other  charge  imposed on or assessed  against the U.S.  Government  Obligations
deposited  pursuant to Section 1204 or the  principal  and interest  received in
respect  thereof other than any such tax, fee or other charge that by law is for
the account of the Holders of Outstanding Securities.

         Anything in this Article  Twelve to the contrary  notwithstanding,  the
Trustee  shall  deliver  or pay to the  Company  from time to time upon  Company
Request  any money or U.S.  Government  Obligations  held by it as  provided  in
Section 1204 that, in the opinion of a nationally recognized firm of independent
public accountants expressed in a written certification thereof delivered to the
Trustee,  are in excess of the amount  thereof that would then be required to be
deposited to effect the Defeasance or Covenant  Defeasance,  as the case may be,
with respect to the Outstanding Securities.

         SECTION  1206.  Reinstatement.  If the  Trustee or the Paying  Agent is
unable to apply any money in accordance with this Article Twelve with respect to
any  Securities of any series by reason of any order or judgment of any court or
governmental  authority  enjoining,  restraining or otherwise  prohibiting  such
application,  then the  obligations  under this Indenture and such Securities of
such series from which the Company has been  discharged or released  pursuant to
Section  1202 or 1203 shall be revived and  reinstated  as though no deposit had
occurred pursuant to this Article Twelve with respect to such Securities of such
series, until such time as the Trustee or Paying Agent is permitted to apply all
money held in trust pursuant to Section 1205 with respect to such  Securities in
accordance  with this Article  Twelve;  provided  that if the Company  makes any
payment of principal of or any premium or interest on any such  Security of such
series following such  reinstatement  of its  obligations,  the Company shall be
subrogated  to the rights (if any) of the  Holders  of such  Securities  of such
series to receive such payment from the money so held in trust.

         This instrument may be executed in any number of counterparts,  each of
which so executed shall be deemed to be an original,  but all such  counterparts
shall together constitute but one and the same instrument.

(B) FORM OF REVERSE OF SENIOR DEBT SECURITY


         This  Security is one of a duly  authorized  issue of Securities of the
Company  designated  as its ___%  Senior  Notes  due  ____  (herein  called  the
"Securities"),  limited in aggregate principal amount of $_____ issued and to be
issued  under an  Indenture,  dated as of October  15, 1997  (herein  called the
"Indenture",  which  term  shall  have  the  meaning  assigned  to  it  in  such
instrument),  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 are subject to redemption upon not less than 30 nor more
than 60 days'  notice by mail,  at any time on or after  _________  __, ____ and
prior to maturity, as a whole or in part, at the election of the Company, at the
following  Redemption Prices (expressed as percentages of the principal amount),
if redeemed during the 12-month period  commencing on or after  __________ __ of
the years indicated,

              Year                            Redemption Price
              ----                            ---------------- 

 



together in the case of any such  redemption with accrued  interest,  if any, to
the Redemption  Date, but interest  installments  whose Stated Maturity is on or
prior  to  such  Redemption  Date  shall  be  payable  to the  Holders  of  such
Securities,  or one or more  Predecessor  Securities,  of record at the close of
business on the  relevant  Record Dates  referred to on the face hereof,  all as
provided in the Indenture.

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


                                      A-4
<PAGE>


         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  percent of the  principal
amount thereof on any Purchase 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 percent of
the  principal  amount  thereof on any  Purchase  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  reduction  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 the Security.

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

         The Indenture  contains  provisions  for  defeasance at any time of the
entire Debt of 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 Indenture also contains  provisions  



                                      A-5
<PAGE>


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 percent in principal  amount
of the Securities of this series at the time Outstanding shall have made written
request to the  Trustee  to  institute  proceedings  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  foregoing
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  redemption,  on or after the
Redemption Date 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
exchangeable  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.

laws or governmental regulations, the Company shall not, directly or indirectly,
sell or otherwise dispose of any of its consolidated properties or assets (other

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 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

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,

                                (REVERSE OF NOTE)


                  This Security is one of a duly authorized issue of Securities
of the Company designated as its 7.63% Senior Notes due 2007 (herein called the
"Securities"), limited in aggregate principal amount of $350,000,000 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 (as so
supplemented, herein called the "Indenture", which term shall have the meaning
assigned to it in such instrument), 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 are not redeemable at the option of the Company
prior to maturity and do not have the benefit of any sinking fund obligations.

                  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 percent of the principal
amount thereof on any Purchase 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 percent of
the principal amount thereof on any Purchase 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 reduction 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.

                  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 purchased shall be issued in the name of the Holder hereof upon surrender of
this Security to the Trustee for cancellation thereof.

                  The Indenture provides that 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


                                       A-4

<PAGE>


                                            FORM OF SUPPLEMENTAL INDENTURE

covenants regarding restrictions or liens and the ability of the Company to
merge or consolidate with or into any other Person or to transferor lease assets
will apply to the Securities.

                  The Indenture contains provisions for defeasance at any time
of the entire Debt of 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 Indenture 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 percent in principal amount
of the Securities of this series at the time Outstanding shall have made written
request to the Trustee to institute proceedings 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 foregoing 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 exchangeable 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.
