         or by the Company and one or more other Subsidiaries. For purposes of
         this definition, "voting stock" means stock that ordinarily has voting

         Section 3.7 in exchange for or in lieu of a mutilated, destroyed, lost
         or stolen Security shall be deemed to evidence the same debt as the
         mutilated, destroyed, lost or stolen Security.

                "Tax Event" means the receipt by an Issuer Trust of an Opinion
         of Counsel (as defined in the relevant Trust Agreement) experienced in
         such matters to the effect that, as a result of any amendment to, or
         change (including any announced prospective change) in, the laws (or
         any regulations thereunder) of the United States or any political
         subdivision or taxing authority thereof or therein, or as a result of
         any official or administrative pronouncement or action or judicial
         decision interpreting or applying such laws or regulations, which
         amendment or change is effective or which pronouncement or decision is
         announced on or after the date of issuance of the Capital Securities of
         such Issuer Trust, there is more than an insubstantial risk that (i)
         such Issuer Trust is, or will be within 90 days of the delivery of such
         Opinion of Counsel, subject to United States Federal income tax with

         States Federal income tax purposes, or (iii) such Issuer Trust is, or
         will be within 90 days of the delivery of such Opinion of Counsel,
         subject to more than a de minimis amount of other taxes, duties or
         other governmental charges.

                "Trust Agreement" means, with respect to any Issuer Trust, the
         trust agreement or other governing instrument of such Issuer Trust.

                "Trustee" means the Person named as the "Trustee" in the first
         paragraph of this Indenture, solely in its capacity as such and not in
         its individual capacity, until a successor Trustee shall have become
         such pursuant to the applicable provisions of this Indenture, and
         thereafter "Trustee" shall mean or include each Person who is then a
         Trustee hereunder and, if at any time there is more than one such
         Person, "Trustee" as used with respect

         Securities of that series.

                "Trust Indenture Act" means the Trust Indenture Act of 1939, as

         any duly appointed vice president, whether or not designated by a
         number or a word or words added before or after the title "vice

                SECTION 1.2.   Compliance Certificate 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 an Officers' Certificate stating that all
         conditions precedent (including covenants compliance with which
         constitutes a condition precedent), if any, provided for in this
         Indenture relating to the proposed action have been complied with and
         an Opinion of Counsel stating that, in the opinion of such counsel, all
         such conditions precedent (including covenants compliance with which
         constitutes a condition precedent), if any, have been complied with,
         except that in the case of any such application or request as to which
         the furnishing of such documents is specifically required by any
         provision of this Indenture relating to such particular application or
         request, no additional certificate or opinion need be furnished.

                Every certificate or opinion with respect to compliance with a
         condition or covenant provided for in this Indenture (other than the
         certificates provided pursuant to Section 10.4) shall include:

                     (1) a statement by each individual signing such certificate
                or opinion that such individual 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 of such individual contained in such certificate or
                opinion are based;

                     (3)  a statement that, in the opinion of such
                individual, he or she has made such examination or
                investigation as is necessary to enable him or her to
<PAGE>   20

                                       - 14 -


                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 such
                individual, such condition or covenant has been complied with.

                SECTION 1.3.   Forms of Documents Delivered to Trustee.

                In any case where several matters are required to be certified
         by, or covered by an opinion of, any specified Person, it is not
         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 matters upon which his or
         her 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.

                Where 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 1.4.   Acts of Holders.

                (a) Any request, demand, authorization, direction, notice,
         consent, waiver or other action provided by this Indenture to be given
         to or taken by Holders 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; and, except as herein
         otherwise expressly provided, such action shall become effective when
         such instrument or instruments is or are delivered to the Trustee, and,
         where it is hereby expressly required, to the Company. Such instrument
         or instruments (and the action embodied therein and evidenced thereby)
         are herein
<PAGE>   21

                                       - 15 -


         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 6.1) conclusive in
         favor of the Trustee and the Company, if made in the manner provided in
         this Section.

                (b) 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 the certificate of any 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 or her the execution thereof. Where such execution is by a Person
         acting in other than his or her individual capacity, such certificate
         or affidavit shall also constitute sufficient proof of his or her
         authority.

                (c) The fact and date of the execution by any Person of any such
         instrument or writing, or the authority of the Person executing the
         same, may also be provided in any other manner that the Trustee deems
         sufficient and in accordance with such reasonable rules as the Trustee
         may determine.

                (d)  The ownership of Securities shall be proved by the
         Securities Register.

                (e) Any request, demand, authorization, direction, notice,
         consent, waiver or other action by the Holder of any Security shall
         bind every future Holder of the same Security and the Holder of every
         Security issued upon the transfer thereof or in exchange therefor or in
         lieu thereof in respect of anything done 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.

                (f) The Company may set any day as a record date for the purpose
         of determining the Holders of Outstanding Securities of any series
         entitled to give, make or take any request, demand, authorization,
         direction, notice, consent, waiver or other action provided or
         permitted by this Indenture to be given, made or taken by Holders of
         Securities of such series, 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 succeeding paragraph. If
         any record date is set pursuant to this paragraph, the Holders of
         Outstanding Securities of the relevant series on such record date, and
         no other Holders, shall be entitled to take the relevant action,
         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 Expiration Date (as defined below) by
         Holders of
<PAGE>   22

                                       - 16 -


         the requisite principal amount of Outstanding Securities of such series
         on such record date. Nothing in this paragraph shall be construed to
         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 by any Person be cancelled and of no effect), and nothing in
         this paragraph shall be construed to render ineffective any action
         taken by Holders of the requisite principal amount of Outstanding
         Securities of the relevant series 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 Expiration Date to be
         given to the Trustee in writing and to each Holder of Securities of the
         relevant series in the manner set forth in Section 1.6.

                The Trustee may set any day as a record date for the purpose of
         determining the Holders of Outstanding Securities of any series
         entitled to join in the giving or making of (i) any Notice of Default,
         (ii) any declaration of acceleration referred to in Section 5.2, (iii)
         any request to institute proceedings referred to in Section 5.7(2), or
         (iv) any direction referred to in Section 5.12, in each case with
         respect to Securities of such series. If any record date is set
         pursuant to this paragraph, the Holders of Outstanding Securities of
         such series 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 Expiration Date by Holders of the
         requisite principal amount of Outstanding Securities of such series on
         such record date. Nothing in this paragraph shall be construed to
         prevent the Trustee 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 by any Person be cancelled and of no effect) and nothing in
         this paragraph shall be construed to render ineffective any action
         taken by Holders of the requisite principal amount of Outstanding
         Securities of the relevant series 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 proposed action by Holders and the applicable Expiration Date
         to be given to the Company in writing and to each Holder of Securities
         of the relevant series in the manner set forth in Section 1.6.

                With respect to any record date set pursuant to this Section,
         the party hereto that sets such record date may designate any day as
         the "Expiration Date" and from time to time may change the Expiration
         Date to any earlier or later day, provided that no
<PAGE>   23

                                       - 17 -


         such change shall be effective unless notice of the proposed new
         Expiration Date is given to the other party hereto in writing, and to
         each Holder of Securities of the relevant series in the manner set
         forth in Section 1.6 on or prior to the existing Expiration Date. If an
         Expiration Date is not designated with respect to any record date set
         pursuant to this Section, the party hereto that set such record date
         shall be deemed to have initially designated the 180th day after such
         record date as the Expiration Date with respect thereto, subject to its
         right to change the Expiration Date as provided in this paragraph.
         Notwithstanding the foregoing, no Expiration Date shall be later than
         the 180th day after the applicable record date.

                (g) 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 1.5.   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, any holder of Capital
                Securities or the Company shall be sufficient for every purpose
                hereunder if made, given, furnished or filed in writing to or
                with the Trustee at its Corporate Trust Office, or

                     (2) the Company by the Trustee, any Holder or any holder of
                Capital Securities shall be sufficient for every purpose (except
                as otherwise provided in Section 5.1) hereunder 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 instrument or at any other
                address previously furnished in writing to the Trustee by the
                Company.

                SECTION 1.6.   Notice to Holders; Waiver.

                Where 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 the address of such
         Holder as it appears in the Securities Register, not later than the
         latest date, and not earlier than the earliest
<PAGE>   24

                                       - 18 -


         date, prescribed for the giving of such notice. If, by reason of the
         suspension of or irregularities in regular mail services or for any
         other reason, it shall be impossible or impracticable to mail notice of
         any event to Holders when said notice is required to be given pursuant
         to any provision of this Indenture or of the relevant Securities, then
         any manner of giving such notice as shall be satisfactory to the
         Trustee shall be deemed to be a sufficient giving of such notice. In
         any case where notice to Holders is given by mail, neither the failure
         to mail such notice, nor any defect in any notice so mailed, to any
         particular Holder shall affect the sufficiency of such notice with
         respect to other Holders. Where 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.

                SECTION 1.7.   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 a part of and govern this Indenture, the provision of the Trust
         Indenture Act 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 1.8.   Effect of Headings and Table of Contents.

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

                SECTION 1.9.   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 1.10.  Separability Clause.

                If any provision in this Indenture or in the Securities 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.

                SECTION 1.11.  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 and assigns, the holders of Senior Indebtedness, the
         Holders of the Securities and, to the extent expressly provided in
         Sections 5.2, 5.8, 5.9, 5.11, 5.13, 9.1 and 9.2, the holders of Capital
         Securities, any benefit or any legal or equitable right, remedy or
         claim under this Indenture.

                SECTION 1.12.  Governing Law.

                THIS INDENTURE AND THE SECURITIES SHALL BE GOVERNED BY AND
         CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.

                SECTION 1.13.  Non-Business Days.

                If any Interest Payment Date, Redemption Date or Stated Maturity

         as the case may be, until such next succeeding Business Day) except
         that, if such Business Day is in the next succeeding calendar year,
         such payment shall be made on the immediately preceding Business Day
         (in each case with the same force and effect as if made on the Interest
         Payment Date or Redemption Date or at the Stated Maturity).

         termination of any such Extension Period and upon the payment of all
         accrued and unpaid interest and any Additional Interest then due on any
         Interest Payment Date, the Company may elect to begin a new Extension
         Period, subject to the above conditions. No interest shall be due and

         of interest may be made (i) by check mailed to the address of the
         Person entitled thereto as such address shall appear in the Securities

         available funds upon written request to the Trustee not later than 15
         calendar days prior to the date on which the interest is payable].

                The indebtedness evidenced by this Security is, to the extent
         provided in the Indenture, subordinate and subject in right of payments
         to the prior payment in full of all Senior Indebtedness, and this
         Security is issued subject to the provisions of the Indenture with
         respect thereto. Each Holder of this Security, by accepting the same,
         (a) agrees to and shall be bound by such provisions, (b) authorizes and
         directs the Trustee on his or her behalf to take such actions as may be
         necessary or appropriate to effectuate the subordination so provided,
         and (c) appoints the Trustee his or her attorney-in-fact for any and
         all such purposes. Each Holder hereof, by his or her acceptance hereof,
         waives all notice of the acceptance of the subordination provisions
         contained herein and in the Indenture by each holder of Senior
         Indebtedness, whether now outstanding or hereafter incurred, and waives
         reliance by each such holder upon said provisions.

         shall for all purposes have the same effect as if set forth at this

         signature, this Security shall not be entitled to any benefit under the
         Indenture or be valid or obligatory for any purpose.

                provisions of this Indenture; and

                     (3) that such Securities, when authenticated and delivered
                by the Trustee and issued by the Company in the manner and
                subject to any conditions specified in such Opinion of Counsel,
                will constitute valid and legally binding obligations of the
                Company enforceable in accordance with their terms, subject to
                bankruptcy, insolvency, fraudulent transfer, reorganization,
                moratorium and similar laws of general applicability relating to
                or affecting creditors' rights and to general equity principles.

         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 or immunities under the Securities and this Indenture or
         otherwise in a manner that is not reasonably acceptable to the Trustee.

                Notwithstanding the provisions of Section 3.1 and the preceding
         paragraph, if all Securities of a series are not to be originally
         issued at one time, it shall not be necessary to deliver the Officers'
         Certificate otherwise required pursuant to Section 3.1 or the Company
         Order and Opinion of Counsel otherwise required pursuant to such
         preceding paragraph at or prior to the authentication of each Security
         of such series if such documents are delivered at or prior to the
         authentication upon original issuance of the first Security of such
         series to be issued.
<PAGE>   41

                                       - 35 -



                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 the manual
         signature of one of its authorized officers or signatories, and such 
         certificate upon any Security shall be conclusive evidence, and the
         only evidence, that such security has been duly authenticated and
         delivered hereunder. Notwithstanding the foregoing, if any Security
         shall have been authenticated and delivered hereunder but never issued
         and sold by the Company, and the Company shall deliver such Security to
         the Trustee for cancellation as provided in Section 3.10, for all
         purposes of this Indenture such Security shall be deemed never to have
         been authenticated and delivered hereunder and shall never be entitled
         to the benefits of this Indenture.
    

                SECTION 3.4.   Temporary Securities.

                Pending the preparation of definitive Securities of any series,
         the Company may execute, and upon receipt of a Company Order the
         Trustee shall authenticate and deliver, temporary Securities that are
         printed, lithographed, typewritten, mimeographed or otherwise produced,
         in any denomination, substantially of the tenor of the definitive
         Securities of such series in lieu of which they are issued and with
         such appropriate insertions, omissions, substitutions and other
         variations as the officers executing such Securities may determine, as
         evidenced by their execution of such Securities.

                If temporary Securities of any series are issued, the Company
         will cause definitive Securities of such series to be prepared without
         unreasonable delay. After the preparation of definitive Securities, the
         temporary Securities shall be exchangeable for definitive Securities
         upon surrender of the temporary Securities at the office or agency of
         the Company designated for that purpose without charge to the Holder.
         Upon surrender for cancellation of any one or more temporary
         Securities, the Company shall execute and the Trustee shall
         authenticate and deliver in exchange therefor one or more definitive
         securities of the same series, of any authorized denominations having
         the same Original Issue Date and Stated Maturity and having the same
         terms as such temporary Securities. Until so exchanged, the temporary
         Securities of any series shall in all respects be entitled to the same
         benefits under this Indenture as definitive Securities of such series.

                SECTION 3.5.   Global Securities.

                (a) Each Global Security issued under this Indenture shall be
         registered in the name of the Depositary designated by the Company for
         such Global Security or a nominee thereof and delivered to such
         Depositary or a nominee thereof or custodian therefor, and each such
         Global Security shall constitute a single Security for all purposes of
         this Indenture.

                (b) Notwithstanding any other provision in this Indenture, no
         Global Security may be exchanged in whole or in part for Securities
         registered, and no transfer of a Global Security in whole or in part
         may be registered, in the name of any Person other than the Depositary
         for such Global Security or a nominee thereof unless (i) such
         Depositary advises the Trustee in writing that such Depositary is no
         longer willing or able to properly discharge its responsibilities as
         Depositary with respect to such Global Security, and the Company is
         unable to locate a qualified successor, (ii) the Company executes and
         delivers to the Trustee a Company Order stating that the Company elects
         to terminate the book-entry system through the Depositary, or (iii)
         there shall have occurred and be continuing an Event of Default.

                (c) If any Global Security is to be exchanged for other
         Securities or cancelled in whole, it shall be surrendered by or on
         behalf of the Depositary or its nominee to the Securities Registrar for
         exchange or cancellation as provided in this Article III. If any Global
         Security is to be exchanged for other Securities or cancelled in part,
         or if another Security is to be exchanged in whole or in part for a
         beneficial interest in any Global Security, then either (i) such Global
         Security shall be so surrendered for exchange or cancellation as
         provided in this Article III or (ii) the principal amount thereof shall
         be reduced, subject to Section 3.6(b)(v), or increased by an amount
         equal to the portion thereof to be so exchanged or cancelled, or equal
         to the principal amount of such other Security to be so exchanged for a
         beneficial interest therein, as the case may be, by means of an
         appropriate adjustment made on the records of the Securities Registrar,
         whereupon the Trustee, in accordance with the Applicable Procedures,
         shall instruct the Depositary or its authorized representative to make
         a corresponding adjustment to its records. Upon any such surrender or
         adjustment of a Global Security by the Depositary, accompanied by
         registration instructions, the Trustee shall, subject to Section 3.6(b)
         and as otherwise provided in this Article III, authenticate and deliver
         any Securities issuable in exchange for such Global Security (or any
         portion thereof) in accordance with the instructions of the Depositary.
         The Trustee shall not be liable for any delay in delivery of such
         instructions and may conclusively rely on, and shall be fully protected
         in relying on, such instructions.

                                       - 37 -


                (d) Every Security authenticated and delivered upon registration
         of transfer of, or in exchange for or in lieu of, a Global Security or
         any portion thereof, whether pursuant to this Article III, Section 9.6
         or 11.6 or otherwise, shall be authenticated and delivered in the form
         of, and shall be, a Global Security, unless such Security is registered
         in the name of a Person other than the Depositary for such Global
         Security or a nominee thereof.

                (e) The Depositary or its nominee, as the registered owner of a
         Global Security, shall be the Holder of such Global Security for all
         purposes under this Indenture and the Securities, and owners of
         beneficial interests in a Global Security shall hold such interests
         pursuant to the Applicable Procedures. Accordingly, any such owner's
         beneficial interest in a Global Security shall be shown only on, and
         the transfer of such interest shall be effected only through, records
         maintained by the Depositary or its nominee or agent. Neither the
         Trustee nor the Securities Registrar shall have any liability in
         respect of any transfers effected by the Depositary.

                (f) The rights of owners of beneficial interests in a Global
         Security shall be exercised only through the Depositary and shall be
         limited to those established by law and agreements between such owners
         and the Depositary and/or its Agent Members.

                SECTION 3.6.   Registration, Transfer and Exchange
                               Generally; Certain Transfers and Exchanges;
                               Securities Act Legends.

                (a) The Company shall cause to be kept at the Corporate Trust
         Office of the Trustee a register in which, subject to such reasonable
         regulations as it may prescribe, the Company shall provide for the
         registration of Securities and transfers of Securities. Such register
         is herein sometimes referred to as the "Securities Register." The
         Trustee is hereby appointed "Securities Registrar" for the purpose of
         registering Securities and transfers of Securities as herein provided.

                Upon surrender for registration of transfer of any Security at
         the offices or agencies of the Company designated for that purpose, the
         Company shall execute, and the Trustee shall authenticate and deliver,
         in the name of the designated transferee or transferees, one or more
         new Securities of the same series of any authorized denominations of
         like tenor and aggregate principal amount and bearing such restrictive
         legends as may be required by this Indenture.

                At the option of the Holder, Securities may be exchanged for
         other Securities of the same series of any authorized denominations, of
         like tenor and aggregate principal amount and
<PAGE>   44

                                       - 38 -


         bearing such restrictive legends as may be required by this Indenture,
         upon surrender of the Securities to be exchanged at such office or
         agency. Whenever any securities are so surrendered for exchange, the
         Company shall execute, and the Trustee shall authenticate and deliver,
         the Securities that the Holder making the exchange is entitled to
         receive.

                All Securities issued upon any transfer or exchange of
         Securities shall be the valid obligations of the Company, evidencing
         the same debt, and entitled to the same benefits under this Indenture,
         as the Securities surrendered upon such transfer or exchange.

                Every Security presented or surrendered for transfer or exchange
         shall (if so required by the Company or the Trustee) be duly endorsed,
         or be accompanied by a written instrument of transfer in form
         satisfactory to the Company and the Securities Registrar, duly executed
         by the Holder thereof or such Holder's attorney duly authorized in
         writing.

                No service charge shall be made to a Holder for any transfer or
         exchange of Securities, but the Company may require payment of a sum
         sufficient to cover any tax or other governmental charge that may be
         imposed in connection with any transfer or exchange of Securities.

                Neither the Company nor the Trustee shall be required, pursuant
         to the provisions of this Section, (i) to issue, register the transfer
         of or exchange any Security of any series during a period beginning at
         the opening of business 15 days before the day of selection for
         redemption of Securities of that series pursuant to Article XI and
         ending at the close of business on the day of mailing of the notice of
         redemption, or (ii) to register the transfer of or exchange any
         Security so selected for redemption in whole or in part, except, in the
         case of any such Security to be redeemed in part, any portion thereof
         not to be redeemed.

                (b) Certain Transfers and Exchanges. Notwithstanding any other
         provision of this Indenture, transfers and exchanges of Securities and
         beneficial interests in a Global Security shall be made only in
         accordance with this Section 3.6(b).

                     (i) Restricted Non-Global Security to Global Security. If
         the Holder of a Restricted Security (other than a Global Security)
         wishes at any time to transfer all or any portion of such Security to a
         Person who wishes to take delivery thereof in the form of a beneficial
         interest in a Global Security, such transfer may be effected only in
         accordance with the provisions of this clause (b)(i) and subject to the
         Applicable Procedures. Upon receipt by the Securities Registrar of (A)
         such Security as provided in Section 3.6(a) and instructions
         satisfactory to the
<PAGE>   45

                                       - 39 -


         Securities Registrar directing that a beneficial interest in the Global
         Security in a specified principal amount not greater than the principal
         amount of such Security be credited to a specified Agent Member's
         account and (B) a Restricted Securities Certificate duly executed by
         such Holder or such Holder's attorney duly authorized in writing, then
         the Securities Registrar shall cancel such Security (and issue a new
         Security in respect of any untransferred portion thereof) as provided
         in Section 3.6(a) and increase the aggregate principal amount of the
         Global Security by the specified principal amount as provided in
         Section 3.5(c).

                     (ii) Non-Global Security to Non-Global Security. A Security
                that is not a Global Security may be transferred, in whole or in
                part, to a Person who takes delivery in the form of another
                Security that is not a Global Security as provided in Section
                3.6(a), provided that if the Security to be transferred in whole
                or in part is a Restricted Security, the Securities Registrar
                shall have received a Restricted Securities Certificate duly
                executed by the transferor Holder or such Holder's attorney duly
                authorized in writing.

                     (iii)  Exchanges Between Global Security and Non-
                Global Security. A beneficial interest in a Global Security
                may be exchanged for a Security that is not a Global Security
                as provided in Section 3.5.

                     (iv) Certain Initial Transfers of Non-Global Securities. In
                the case of Securities initially issued other than in global
                form, an initial transfer or exchange of such Securities that
                does not involve any change in beneficial ownership may be made
                to an Institutional Accredited Investor or Investors as if such
                transfer or exchange were not an initial transfer or exchange;
                provided that written certification shall be provided by the
                transferee and transferor of such Securities to the Securities
                Registrar that such transfer or exchange does not involve a
                change in beneficial ownership.

                (c)  Restricted Securities Legend.  Except as set forth
         below, all Securities shall bear a Restricted Securities Legend:

                     (i) subject to the following clauses of this Section
                3.6(c), a Security or any portion thereof that is exchanged,
                upon transfer or otherwise, for a Global Security or any portion
                thereof shall bear the Restricted Securities Legend while
                represented thereby;

                     (ii) subject to the following clauses of this Section
                3.6(c), a new Security which is not a Global Security and is
                issued in exchange for another Security
<PAGE>   46

                                       - 40 -


                (including a Global Security) or any portion thereof, upon
                transfer or otherwise, shall, if such new Security is required
                pursuant to Section 3.6(b)(ii) or (iii) to be issued in the form
                of a Restricted Security, bear a Restricted Securities Legend;

                     (iii) a new Security (other than a Global Security) that
                does not bear a Restricted Securities Legend may be issued in
                exchange for or in lieu of a Restricted Security or any portion
                thereof that bears such a legend if, in the Company's judgment,
                placing such a legend upon such new Security is not necessary to
                ensure compliance with the registration requirements of the
                Securities Act, and the Trustee, at the written direction of the
                Company in the form of an Officers' Certificate, shall
                authenticate and deliver such a new Security as provided in this
                Article III;

                     (iv) notwithstanding the foregoing provisions of this
                Section 3.6(c), a Successor Security of a Security that does not
                bear a Restricted Securities Legend shall not bear such form of
                legend unless the Company has reasonable cause to believe that
                such Successor Security is a "restricted security" within the
                meaning of Rule 144, in which case the Trustee, at the written
                direction of the Company in the form of an Officers'
                Certificate, shall authenticate and deliver a new Security
                bearing a Restricted Securities Legend in exchange for such
                Successor Security as provided in this Article III; and

                     (v) Securities distributed to a holder of Capital
                Securities upon dissolution of an Issuer Trust shall bear a
                Restricted Securities Legend if the Capital Securities so
                held bear a similar legend.

                SECTION 3.7.   Mutilated, Lost and Stolen Securities.

                If any mutilated Security is surrendered to the Trustee together
         with such security or indemnity as may be required by the Company or
         the Trustee to save each of them harmless, the Company shall execute
         and the Trustee shall authenticate and deliver in exchange therefor a
         new Security of the same series, of like tenor and aggregate principal
         amount, bearing the same legends, and bearing a number not
         contemporaneously outstanding.

                If there shall be delivered to the Company and to 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 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
<PAGE>   47

                                       - 41 -


         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, of like tenor and aggregate principal
         amount and bearing the same legends as such destroyed, lost or stolen
         Security, and bearing a number not contemporaneously outstanding.

                If 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 3.7,
         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 issued pursuant to this Section in lieu of
         any destroyed, lost or stolen Security shall constitute an original
         additional contractual obligation of the Company, whether or not the
         destroyed, lost or stolen Security shall be at any time enforceable by
         anyone, and shall be entitled to all the benefits of this Indenture
         equally and proportionately with any and all other Securities of such
         series duly issued hereunder.

                The provisions of this Section are exclusive and shall preclude
         (to the extent lawful) all other rights and remedies with respect to
         the replacement or payment of mutilated, destroyed, lost or stolen
         Securities.

                SECTION 3.8.   Payment of Interest and Additional Interest;
                               Interest Rights Preserved.

                Interest and Additional Interest on any Security of any series
         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 in
         respect of Securities of such series, except that, unless otherwise
         provided in the Securities of such series, interest payable on the
         Stated Maturity of the principal of a Security shall be paid to the
         Person to whom principal is paid. The initial payment of interest on
         any Security of any series that is issued between a Regular Record Date
         and the related Interest Payment Date shall be payable as provided in
         such Security or in the Board Resolution pursuant to Section 3.1 with
         respect to the related series of Securities.

                Any interest on any Security that is due and payable, but is not
         timely paid or duly provided for, on any Interest Payment
<PAGE>   48

                                       - 42 -


         Date for Securities of such series (herein called "Defaulted
         Interest"), shall forthwith cease to be payable to the registered
         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 in respect of which interest is in default (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 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 in this clause provided. Thereupon, the Trustee
                shall fix a Special Record Date for the payment of such
                Defaulted Interest, which 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 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 mailed, first class, postage prepaid,
                to each Holder of a Security of such series at the address of
                such Holder as it appears in the Securities Register not less
                than 10 days prior to such Special Record Date. The Trustee may,
                in its discretion, in the name and at the expense of the
                Company, cause a similar notice to be published at least once in
                a newspaper, customarily published in the English language on
                each Business Day and of general circulation in the Borough of
                Manhattan, The City of New York, but such publication shall not
                be a condition precedent to the establishment of such Special
                Record Date. Notice of the proposed payment of such Defaulted
                Interest and the Special Record Date therefor having been mailed
                as aforesaid, such Defaulted Interest shall be paid to the
                Persons in whose names the Securities of such series (or their
                respective Predecessor Securities) are registered on such
                Special Record Date and

                                       - 43 -


                shall no longer be payable pursuant to the following clause
                (2).

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

                Subject to the foregoing provisions of this Section, each
                Security delivered under this Indenture upon 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 interest,
                that were carried by such other Security.

                SECTION 3.9.   Persons Deemed Owners.

                The Company, the Trustee and any agent of the Company or the
         Trustee shall treat the Person in whose name any Security is registered
         as the owner of such Security for the purpose of receiving payment of
         principal of and (subject to Section 3.8) any 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.

                No holder of any beneficial interest in any Global Security held
         on its behalf by a Depositary shall have any rights under this
         Indenture with respect to such Global Security, and such Depositary may
         be treated by the Company, the Trustee and any agent of the Company or
         the Trustee as the owner of such Global Security 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 a Depositary or impair, as between a
         Depositary and such holders of beneficial interests, the operation of
         customary practices governing the exercise of the rights of the
         Depositary (or its nominee) as Holder of any Security.

                SECTION 3.10.  Cancellation.

                All Securities surrendered for payment, redemption, transfer or
         exchange shall, if surrendered to any Person other than the Trustee, be
         delivered to the Trustee, and any such Securities and Securities
         surrendered directly to the Trustee for
<PAGE>   50

                                       - 44 -


         any such purpose shall be promptly canceled by it. The Company 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 canceled by the Trustee. No Securities shall be
         authenticated in lieu of or in exchange for any Securities canceled as
         provided in this Section, except as expressly permitted by this
         Indenture. All canceled Securities shall be destroyed by the Trustee
         and the Trustee shall deliver to the Company a certificate of such
         destruction.

                SECTION 3.11.  Computation of Interest.

                Except as otherwise specified as contemplated by Section 3.1 for
         Securities of any series, interest on the Securities of each series for
         any period shall be computed on the basis of a 360-day year of twelve
         30-day months and the actual number of days elapsed in any partial
         month in such period, and interest on the Securities of each series for
         a full period shall be computed by dividing the rate per annum by the
         number of interest periods that together constitute a full twelve
         months.

                SECTION 3.12.  Deferrals of Interest Payment Dates.

                If specified as contemplated by Section 2.1 or Section 3.1 with
         respect to the Securities of a particular series, so long as no Event
         of Default has occurred and is continuing, the Company shall have the
         right, at any time during the term of such series, from time to time to
         defer the payment of interest on such Securities for such period or
         periods (each an "Extension Period") not to exceed the number of
         consecutive quarterly, semi-annual or other periods that equal five
         years with respect to each Extension Period, during which Extension
         Periods the Company shall, if so specified as contemplated by Section
         3.1, have the right to make partial payments of interest on any
         Interest Payment Date. No Extension Period shall end on a date other
         than an Interest Payment Date. At the end of any such Extension Period,
         the Company shall pay all interest then accrued and unpaid on the
         Securities (together with Additional Interest thereon, if any, at the
         rate specified for the Securities of such series to the extent
         permitted by applicable law); provided, however, that no Extension
         Period shall extend beyond the Stated Maturity of the principal of the
         Securities of such series; and provided further, however, that, during
         any such Extension Period, the Company shall not (i) declare or pay any
         dividends or distributions on, or redeem, purchase, acquire or make a
         liquidation payment with respect to, any of the Company's capital
         stock, or (ii) make any payment of principal of or interest or premium,
         if any, on or repay, repurchase or redeem any debt securities of the
         Company that rank pari passu in all respects with or junior in interest
         to the Securities of such series (other than (a) repurchases,
         redemptions

         or other acquisitions of shares of capital stock of the Company in
         connection with any employment contract, benefit plan or other similar
         arrangement with or for the benefit of any one or more employees,
         officers, directors or consultants, in connection with a dividend
         reinvestment or stockholder stock purchase plan or in connection with
         the issuance of capital stock of the Company (or securities convertible
         into or exercisable for such capital stock) as consideration in an
         acquisition transaction entered into prior to the applicable Extension
         Period, (b) as a result of an exchange or conversion of any class or
         series of the Company's capital stock (or any capital stock of a
         Subsidiary of the Company) for any class or series of the Company's
         capital stock or of any class or series of the Company's indebtedness
         for any class or series of the Company's capital stock, (c) the
         purchase of fractional interests in shares of the Company's capital
         stock pursuant to the conversion or exchange provisions of such capital
         stock or the security being converted or exchanged, (d) any declaration
         of a dividend in connection with any Rights Plan, or the issuance of
         rights, stock or other property under any Rights Plan, or the
         redemption or repurchase of rights pursuant thereto, or (e) any
         dividend in the form of stock, warrants, options or other rights where
         the dividend stock or the stock issuable upon exercise of such
         warrants, options or other rights is the same stock as that on which
         the dividend is being paid or ranks pari passu with or junior to such
         stock). Prior to the termination of any such Extension Period, the
         Company may further defer the payment of interest, provided that no
         Event of Default has occurred and is continuing and provided further,
         that no Extension Period shall exceed the period or periods specified
         in such Securities, extend beyond the Stated Maturity of the principal
         of such Securities or end on a date other than an Interest Payment
         Date. Upon the termination of any such Extension Period and upon the
         payment of all accrued and unpaid interest and any Additional Interest
         then due on any Interest Payment Date, the Company may elect to begin a
         new Extension Period, subject to the above conditions. No interest or
         Additional Interest shall be due and payable during an Extension
         Period, except at the end thereof, but each installment of interest
         that would otherwise have been due and payable during such Extension
         Period shall bear Additional Interest as and to the extent as may be
         specified as contemplated by Section 3.1. The Company shall give the
         Holders of the Securities of such series and the Trustee notice of its
         election to begin any such Extension Period at least one Business Day
         prior to the next succeeding Interest Payment Date on which interest on
         Securities of such series would be payable but for such deferral or,
         with respect to any Securities of a series issued to an Issuer Trust,
         so long as any such Securities are held by such Issuer Trust, at least
         one Business Day prior to the earlier of (i) the next succeeding date
         on which Distributions on the Capital Securities of such Issuer Trust
         would be payable but for such deferral, and (ii) the date on which the
         Property Trustee of such Issuer Trust is required to
    
<PAGE>   52

                                       - 46 -


         give notice to holders of such Capital Securities of the record date or
         the date such Distributions are payable, but in any event not less than
         one Business Day prior to such record date.

                The Trustee shall promptly give notice of the Company's election
         to begin any such Extension Period to the Holders of the Outstanding
         Securities of such series.

                SECTION 3.13.  Right of Set-Off.

                With respect to the Securities of a series initially issued to
         an Issuer Trust, notwithstanding anything to the contrary herein, the
         Company shall have the right to set off any payment it is otherwise
         required to make in respect of any such Security to the extent the
         Company has theretofore made, or is concurrently on the date of such
         payment making, a payment under the Guarantee relating to such Security
         or to a holder of Capital Securities pursuant to an action undertaken
         under Section 5.8 of this Indenture.

                SECTION 3.14.  Agreed Tax Treatment.

                Each Security issued hereunder shall provide that the Company
         and, by its acceptance of a Security or a beneficial interest therein,
         the Holder of, and any Person that acquires a beneficial interest in,
         such Security agree that for United States Federal, state and local tax
         purposes it is intended that such Security constitutes indebtedness.

                SECTION 3.15.  Shortening or Extension of Stated Maturity.

   
                If specified as contemplated by Section 2.1 or Section 3.1 with
         respect to the Securities of a particular series, the Company shall
         have the right to (i) shorten the Stated Maturity of the principal of
         the Securities of such series at any time to any date and (ii) extend
         the Stated Maturity of the principal of the Securities of such series
         at any time at its election for one or more periods, provided that, if
         the Company elects to exercise its right to extend the Stated Maturity
         of the principal of the Securities of such series pursuant to clause
         (ii) above, at the time such election is made and at the time of
         extension, such conditions as may be specified in such Securities shall
         have been satisfied; and, provided further, that if the Company elects
         to shorten the Stated Maturity of the principal of the Securities of
         such series pursuant to clause (i) above, it shall (A) obtain prior
         approval of the Federal Reserve if then required under applicable
         capital guidelines or policies of the Federal Reserve and (B) give 
         notice to the registered holders of such Securities, the Trustee and
         the Issuer Trust of such shortening no less than 90 days prior to the
         effectiveness thereof.
    

                SECTION 3.16 CUSIP Numbers.

                The Company, in issuing the Securities, may use "CUSIP" numbers
         (if then generally in use), and, if so, the Trustee shall use "CUSIP"
         numbers in notice of redemption and other similar or related materials
         as a convenience to Holders; provided that any such notice or other
         materials may state that no representation is
<PAGE>   53

                                       - 47 -


         made as to the correctness of such numbers either as printed on the
         Securities or as contained in any notice of redemption or other
         materials and that reliance may be placed only on the other
         identification numbers printed on the Securities, and any such
         redemption shall not be affected by any defect in or omission of such
         numbers.

                           SATISFACTION AND DISCHARGE

                SECTION 4.1.   Satisfaction and Discharge of Indenture.

                This Indenture shall, upon Company Request, cease to be of
         further effect (except as to any surviving rights of registration of
         transfer or exchange of Securities herein expressly provided for and as
         otherwise provided in this Section 4.1) and the Trustee, on demand of
         and at the expense of the Company, shall execute proper instruments
         acknowledging satisfaction and discharge of this Indenture, when

                     (1)  either

                          (A) all Securities theretofore authenticated and
                     delivered (other than (i) Securities that have been
                     destroyed, lost or stolen and that have been replaced or
                     paid as provided in Section 3.7 and (ii) Securities for
                     whose payment money has theretofore been deposited in trust

                     trust, as provided in Section 10.3) have been delivered to
                     the Trustee for cancellation; or

                          (B)  all such Securities not theretofore
                     delivered to the Trustee for cancellation

                               (i)    have become due and payable, or

                               (ii)   will become due and payable at their
                          Stated Maturity within one year of the date of
                          deposit, or

                               (iii) are to be called for redemption within one
                          year under arrangements satisfactory to the Trustee
                          for the giving of notice of redemption by the Trustee
                          in the name, and at the expense, of the Company,


                and the Company, in the case of subclause (B)(i), (ii) or
                (iii) above, has deposited or caused to be deposited with

                in the currency or currencies in which the Securities of such
                series are payable sufficient to pay and discharge the entire
                indebtedness on such Securities not theretofore delivered to the
                Trustee for cancellation, for the principal (and premium, if
                any) and interest (including any Additional Interest) to the
                date of such deposit (in the case of Securities that have become
                due and payable) or to the Stated Maturity or Redemption Date,
                as the case may be;

                     (2)  the Company has paid or caused to be paid all
                other sums payable hereunder by the Company; and

                     (3) the Company has delivered to the Trustee an Officers'
                Certificate and an Opinion of Counsel each stating that all
                conditions precedent herein provided for relating to the
                satisfaction and discharge of this Indenture have been complied
                with.

                been deposited with the Trustee pursuant to subclause (B) of
                clause (1) of this Section, the obligations of the Trustee under
                Section 4.2 and the last paragraph of Section 10.3 shall
                survive.


                SECTION 4.2.   Application of Trust Money.

                Subject to the provisions of the last paragraph of Section 10.3,
         all money deposited with the Trustee pursuant to Section 4.1 shall be
         held in trust and applied by the Trustee, in accordance with the
         provisions of the Securities and this Indenture, to the payment, either
         directly or through any Paying Agent (including the Company acting as
         its own Paying Agent) as the Trustee may determine, to the Persons
         entitled thereto, of the principal (and premium, if any) and interest
         and Additional Interest for the payment of which such money or
         obligations have been deposited with or received by the Trustee.

         (whatever the reason for such Event of Default and whether

                respect thereof, when it becomes due and payable, and
                continuance of such default for a period of 30 days (subject to
                the deferral of any due date in the case of an Extension
                Period); or

                     (2) default in the payment of the principal of (or
                premium, if any, on) any Security of that series at its
                Maturity; or

                     (3) failure on the part of the Company duly to observe or
                perform any other of the covenants or agreements on the part of
                the Company in the Securities of that series or in this
                Indenture for a period of 90 days after the date on which
                written notice of such failure, requiring the Company to remedy
                the same, shall have been given to the Company by the Trustee by
                registered or certified mail or to the Company and the Trustee
                by the Holders of at least 25% in aggregate principal amount of

                     (5) any other Event of Default provided with respect to

                               Annulment.

                If an Event of Default (other than an Event of Default specified
         in Section 5.1(4)) with respect to Securities of any series at the time
         Outstanding occurs and is continuing, then, and in every such case, the
         Trustee or the Holders of not less than 25% in aggregate principal
         amount of the Outstanding Securities of that series may declare the
         principal amount (or, if the Securities of that series are Discount
         Securities, such portion of the principal amount as may be specified in
         the terms of that series) of all the Securities of that series to be
         due and payable

                                       - 50 -


         immediately, by a notice in writing to the Company (and to the Trustee
         if given by Holders), provided that, in the case of the Securities of a
         series issued to an Issuer Trust, if, upon an Event of Default, the
         Trustee or the Holders of not less than 25% in principal amount of the
         Outstanding Securities of such series fail to declare the principal of
         all the Outstanding Securities of such series to be immediately due and
         payable, the holders of at least 25% in aggregate Liquidation Amount
         (as defined in the related Trust Agreement) of the related series of
         Capital Securities issued by such Issuer Trust then outstanding shall
         have the right to make such declaration by a notice in writing to the
         Company and the Trustee; and upon any such declaration such principal
         amount (or specified portion thereof) of and the accrued interest
         (including any Additional Interest) on all the Securities of such
         series shall become immediately due and payable. If an Event of Default
         specified in Section 5.1(4) with respect to Securities of any series at
         the time Outstanding occurs, the principal amount of all the Securities
         of such series (or, if the Securities of such series are Discount
         Securities, such portion of the principal amount of such Securities as
         may be specified by the terms of that series) shall automatically, and
         without any declaration or other action on the part of the Trustee or
         any Holder, become immediately due and payable. Payment of principal
         and interest (including any Additional Interest) on such Securities
         shall remain subordinated to the extent provided in Article XIII
         notwithstanding that such amount shall become immediately due and
         payable as herein provided.

                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 provided, the Holders of a majority in
         aggregate 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 installments of interest on all
                Securities of such series;

                          (B)  any accrued Additional Interest on all
                Securities of such series;

                          (C) the principal of (and premium, if any, on) any
                Securities of such series that have become due otherwise than by
                such declaration of acceleration and interest and Additional
                Interest thereon at the rate borne by the Securities; and
<PAGE>   57

                                       - 51 -



                          (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

                     (2) all Events of Default with respect to Securities of
                that series, other than the non-payment of the principal of
                Securities of that series that has become due solely by such
                acceleration, have been cured or waived as provided in Section
                5.13.


                In the case of Securities of a series initially issued to an
         Issuer Trust, if the Holders of such Securities fail to annul such
         declaration and waive such default, the holders of a majority in
         aggregate Liquidation Amount (as defined in the related Trust
         Agreement) of the related series of Capital Securities issued by such
         Issuer Trust then outstanding shall also have the right to rescind and
         annul such declaration and its consequences by written notice to the
         Company and the Trustee, subject to the satisfaction of the conditions
         set forth in clauses (1) and (2) above of this section 5.2.

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

                SECTION 5.3.   Collection of Indebtedness and Suits for
                               Enforcement by Trustee.

                The Company covenants that if:

                     (1) default is made in the payment of any installment of
                interest (including any Additional 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 (and premium, if any, on) any Security at the Maturity
                thereof,

                the Company will, upon demand of the Trustee, pay to the
                Trustee, for the benefit of the Holders of such Securities, the
                whole amount then due and payable on such Securities for
                principal (and premium, if any) and interest (including any
                Additional Interest), and, in addition thereto,all amounts owing
                the Trustee under Section 6.7.
<PAGE>   58

                                       - 52 -


                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, and may prosecute such proceeding to judgment
         or final decree, and may enforce the same against the Company or any
         other obligor upon such Securities and collect the monies 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, 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 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 5.4.   Trustee May File Proofs of Claim.

                In case of any receivership, insolvency, liquidation,
         bankruptcy, reorganization, arrangement, adjustment, composition or
         other judicial or administrative proceeding relative to the Company or
         any other obligor upon the Securities or the property of the Company or
         of such other obligor or their creditors,

                (a) the Trustee (irrespective of whether the principal of the
         Securities of any series shall then be due and payable as therein
         expressed or by declaration or otherwise and irrespective of whether
         the Trustee shall have made any demand on the Company for the payment
         of overdue principal (and premium, if any) or interest (including any
         Additional Interest)) shall be entitled and empowered, by intervention
         in such proceeding or otherwise,

                     (i) to file and prove a claim for the whole amount of
                principal (and premium, if any) and interest (including any
                Additional Interest) owing and unpaid in respect to the
                Securities and to file such other papers or documents as may be
                necessary or advisable and to take any and all actions as are
                authorized under the Trust Indenture Act in order to have the
                claims of the Holders and any predecessor to the Trustee under
                Section 6.7 allowed in any such judicial or administrative
                proceedings; and

                     (ii) in particular, the Trustee shall be authorized to
                collect and receive any monies or other property payable or
                deliverable on any such claims and to distribute the same in
                accordance with Section 5.6; and
<PAGE>   59

                                       - 53 -


                (b) any custodian, receiver, assignee, trustee, liquidator,
         sequestrator, conservator (or other similar official) in any such
         judicial or administrative proceeding is hereby authorized by each
         Holder to make such payments to the Trustee for distribution in
         accordance with Section 5.6, 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 to it and any predecessor Trustee under
         Section 6.7.

                Nothing herein contained shall be deemed to authorize the
         Trustee to authorize or consent to accept or adopt on behalf of any
         Holder any plan of reorganization, arrangement, adjustment or
         composition affecting the Securities 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, however, that the Trustee
         may, on behalf of the 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 5.5.   Trustee May Enforce Claim 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, subject to Article XIII and
         after provision for the payment of all the amounts owing the Trustee
         and any predecessor Trustee under Section 6.7, 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 5.6 Application of Money Collected.

                Any money or property collected or to be applied by the Trustee
         with respect to a series of Securities pursuant to this Article 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 or property on
         account of principal (or premium, if any) or interest (including any
         Additional 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 and
         any predecessor Trustee under Section 6.7;

         principal (and premium, if any) and interest (including any Additional
         Interest) 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 series of
         Securities for principal (and premium, if any) and interest (including
         any Additional Interest), respectively; and

                THIRD:    The balance, if any, to the Person or Persons
         entitled thereto.

                SECTION 5.7 Limitation on Suits.

                Subject to Section 5.8, no Holder of any Securities 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, assignee, trustee, liquidator, sequestrator (or other similar
         official) 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;

                     (2) the Holders of not less than 25% in aggregate 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 aggregate principal amount of the
                Outstanding Securities of that series;

                it being understood and intended that no one or more of such
                Holders shall have any right in any manner whatever by virtue
                of, or by availing itself of, any provision of this Indenture to
                affect, disturb or prejudice the rights of any other Holders of
                Securities, or to obtain or to seek to obtain priority or
                preference over any other of such Holders or to enforce any
                right under this Indenture,
<PAGE>   61

                                       - 55 -


                except in the manner herein provided and for the equal and
                ratable benefit of all such Holders.


                SECTION 5.8.   Unconditional Right of Holders to Receive
                               Principal, Premium and Interest; Direct
                               Action by Holders of Preferred
                               Securities.

                Notwithstanding any other provision in this Indenture, the
         Holder of any Security of any series shall have the right, which is
         absolute and unconditional, to receive payment of the principal of (and
         premium, if any) and (subject to Sections 3.8 and 3.12) interest
         (including any Additional Interest) on such Security on the respective
         Stated Maturities expressed in such Security (or in the case of
         redemption, on the Redemption Date) and to institute suit for the
         enforcement of any such payment, and such right shall not be impaired
         without the consent of such Holder. In the case of Securities of a
         series issued to an Issuer Trust, any registered holder of the series
         of Capital Securities issued by such Issuer Trust shall have the right,
         upon the occurrence of an Event of Default described in Section 5.1(1)
         or 5.1(2), to institute a suit directly against the Company for
         enforcement of payment to such holder of principal of (premium, if any)

         Additional Interest) on the Securities having a principal amount equal
         to the aggregate Liquidation Amount (as defined in the related Trust
         Agreement) of such Capital Securities held by such holder.

                SECTION 5.9.   Restoration of Rights and Remedies.

                If the Trustee, any Holder or any holder of Capital Securities
         issued by any Issuer Trust 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, such Holder or such holder of Capital
         Securities, then, and in every such case, the Company, the Trustee,
         such Holders and such holder of Capital Securities shall, subject to
         any determination in such proceeding, be restored severally and
         respectively to their former positions hereunder, and thereafter all
         rights and remedies of the Trustee, such Holder and such holder of
         Capital Securities shall continue as though no such proceeding had been
         instituted.

                SECTION 5.10.  Rights and Remedies Cumulative.

                Except as otherwise provided in the last paragraph of Section
         3.7, no right or remedy herein conferred upon or reserved to the
         Trustee or the Holders is intended to be exclusive of any other right
         or remedy, and every right and remedy shall, to the

                                       - 56 -


         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 5.11.  Delay or Omission Not Waiver.

                No delay or omission of the Trustee, any Holder of any Security
         with respect to the Securities of the related series or any holder of
         any Capital Security to exercise any right or remedy accruing upon any
         Event of Default with respect to the Securities of the related series
         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 or by law to the
         Trustee or to the Holders and the right and remedy given to the holders
         of Capital Securities by Section 5.8 may be exercised from time to
         time, and as often as may be deemed expedient, by the Trustee, the
         Holders or the holders of Capital Securities, as the case may be.

                SECTION 5.12.  Control by Holders.

                The Holders of not less than a majority in aggregate 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,

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

                     (3) subject to the provisions of Section 6.1, the Trustee
                shall have the right to decline to follow such direction if a
                Responsible Officer or Officers of the Trustee shall, in good
                faith, determine that the proceeding so directed would be
                unjustly prejudicial to the Holders not joining in any such
                direction or would involve the Trustee in personal liability.

                SECTION 5.13.  Waiver of Past Defaults.

                The Holders of not less than a majority in aggregate principal
         amount of the Outstanding Securities of any series affected thereby
         and, in the case of any Securities of a series initially issued to an
         Issuer Trust, the holders of a majority in aggregate Liquidation Amount
         (as defined in the related Trust Agreement) of the Capital Securities
         issued by such Issuer Trust may waive any past default hereunder and
         its consequences with respect to such series except a default:

                     (1) in the payment of the principal of (or premium, if any)
                or interest (including any Additional Interest) on any Security
                of such series (unless such default has been cured and the
                Company has paid to or deposited with the Trustee a sum
                sufficient to pay all matured installments of interest
                (including Additional Interest) and all principal of (and
                premium, if any, on) all Securities of that series due otherwise
                than by acceleration), or

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

                Any such waiver shall be deemed to be on behalf of the Holders
         of all the Securities of such series, or in the case of waiver by
         holders of Capital Securities issued by such Issuer Trust, by all
         holders of Capital Securities issued by such Issuer Trust.

                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 5.14.  Undertaking for Costs.

                All parties to this Indenture agree, and each Holder of any
         Security by his acceptance thereof shall be deemed to have agreed, that
         any court may, in its discretion, require, 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 or omitted by it as Trustee,
         the filing by any party litigant in such suit of an undertaking to pay
         the costs of such suit, and that such court may, in its discretion,
         assess reasonable costs, including reasonable attorneys' fees, against
         any party litigant in such suit, having due regard to the merits and
         good faith of the claims or defenses made by such party litigant, but
         the provisions of this Section shall not apply to any suit instituted
         by the
<PAGE>   64

                                       - 58 -


         Trustee, to any suit instituted by any Holder, or group of Holders,
         holding in the aggregate more than 10% in aggregate principal amount of
         the Outstanding Securities of any series, or to any suit instituted by
         any Holder for the enforcement of the payment of the principal of (or
         premium, if any) or interest (including any Additional Interest) on any
         Security on or after the respective Stated Maturities expressed in such
         Security.

                SECTION 5.15.  Waiver of Usury, Stay or Extension Laws.

                The Company covenants (to the extent that it may lawfully do so)
         that it will 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 will not hinder, delay or impede the execution of any
         power herein granted to the Trustee, but will suffer and permit the
         execution of every such power as though no such law had been enacted.


                                   ARTICLE VI
                                   THE TRUSTEE

                SECTION 6.1.   Certain Duties and Responsibilities.

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

                     (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 provisions 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.


                (b) 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 person would
<PAGE>   65

                                       - 59 -


         exercise or use under the circumstances in the conduct of his or
         her own affairs.

                (c) 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 shall not be construed to limit
                the effect of subsection (a) of this Section;

                     (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; and

                     (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 Holders pursuant to Section
                5.12 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 with respect to the Securities of a series.

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

                (e) 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.

                SECTION 6.2.   Notice of Defaults.

                Within 90 days after actual knowledge by a Responsible Officer
         of the Trustee of the occurrence of any default hereunder with respect
         to the Securities of any series, the Trustee shall transmit by mail to
         all Holders of Securities of such series, as their names and addresses
         appear in the Securities Register, notice of such default, unless such
         default shall have been cured or waived; provided, however, that,
         except in the case of a default in the payment of the principal of (or
         premium, if any) or interest (including any Additional Interest) on any
         Security of such series, the Trustee shall be protected in withholding
         such notice if and so long as the board of directors, the executive
<PAGE>   66

                                       - 60 -


         committee or a trust committee of directors and/or Responsible Officers
         of the Trustee in good faith determines that the withholding of such
         notice is in the interests of the Holders of Securities of such series;
         and provided further, that, in the case of any default of the character
         specified in Section 5.1(3), no such notice to Holders of Securities of
         such series shall be given until at least 30 days after the occurrence
         thereof. For the purpose of this Section, the term "default" means any
         event that is, or after notice or lapse of time or both would become,
         an Event of Default with respect to Securities of such series.

                SECTION 6.3.   Certain Rights of Trustee.

                Subject to the provisions of Section 6.1:

                (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, Security 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 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;

                (d) the Trustee may consult with counsel and the 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 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,
<PAGE>   67

                                       - 61 -


         request, direction, consent, order, bond, indenture, Security or other
         paper or document, but the Trustee in its discretion may make such
         inquiry or investigation into such facts or matters as it may see fit,
         and, if the Trustee shall determine to make such inquiry or
         investigation, it shall be entitled to examine the books, records and
         premises of the Company, personally or by agent or attorney; and

                (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.

                SECTION 6.4.   Not Responsible for Recitals or Issuance of
                               Securities.

                The recitals contained herein and in the Securities, except the
         Trustee's certificates of authentication, shall be taken as the
         statements of the Company, and neither the Trustee nor any
         Authenticating Agent assumes any responsibility for their correctness.
         The Trustee makes no representations as to the validity or sufficiency
         of this Indenture or of the Securities. Neither the Trustee nor any
         Authenticating Agent shall be accountable for the use or application by
         the Company of the Securities or the proceeds thereof.

                SECTION 6.5.   May Hold Securities.

                The Trustee, any Authenticating Agent, any Paying Agent, any
         Securities 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 6.8 and 6.13, may otherwise deal
         with the Company with the same rights it would have if it were not
         Trustee, Authenticating Agent, Paying Agent, Securities Registrar or
         such other agent.

                SECTION 6.6.   Money Held in Trust.

                Money held by the Trustee in trust hereunder need not be
         segregated from other funds except to the extent required by law. The
         Trustee shall be under no liability for interest on any money received
         by it hereunder except as otherwise agreed with the Company.

                SECTION 6.7.   Compensation and Reimbursement.

                (a) The Company agrees to pay to the Trustee from time to time
         reasonable compensation for all services rendered by it hereunder in
         such amounts as the Company and the Trustee shall agree from time to
         time (which compensation shall not be limited
<PAGE>   68

                                       - 62 -


         by any provision of law in regard to the compensation of a trustee
         of an express trust).

                (b) The Company agrees 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.

                (c) Since the Issuer Trust is being formed solely to facilitate
         an investment in the Capital Securities, the Company, as Holder of the
         Common Securities, hereby covenants to pay all debts and obligations
         (other than with respect to the Capital Securities and the Common
         Securities) and all reasonable costs and expenses of the Issuer Trust
         (including without limitation all costs and expenses relating to the
         organization of the Issuer Trust, the fees and expenses of the trustees
         and all reasonable costs and expenses relating to the operation of the
         Issuer Trust) and to pay any and all taxes, duties, assessments or
         governmental charges of whatever nature (other than withholding taxes)
         imposed on the Issuer Trust by the United States, or any taxing
         authority, so that the net amounts received and retained by the Issuer
         Trust and the Property Trustee after paying such expenses will be equal
         to the amounts the Issuer Trust and the Property Trustee would have
         received had no such costs or expenses been incurred by or imposed on
         the Issuer Trust. The foregoing obligations of the Company are for the
         benefit of, and shall be enforceable by, any person to whom any such
         debts, obligations, costs, expenses and taxes are owed (each, a
         "Creditor") whether or not such Creditor has received notice thereof.
         Any such Creditor may enforce such obligations directly against the
         Company, and the Company irrevocably waives any right or remedy to
         require that any such Creditor take any action against the Issuer Trust
         or any other person before proceeding against the Company. The Company
         shall execute such additional agreements as may be necessary or
         desirable to give full effect to the foregoing.

                (d) The Company shall indemnify the Trustee for, and hold it
         harmless against, any loss, liability or expense (including the
         reasonable compensation and the expenses and disbursements of its
         agents and counsel) incurred without negligence or bad faith, arising
         out of or in connection with the acceptance or administration of this
         trust or the performance of its duties hereunder, including the
         reasonable costs and expenses of defending itself against any claim or
         liability in connection with the exercise or performance of any of its
         powers or duties hereunder. This indemnification shall survive the
         termination of this Indenture or the resignation or removal of the
         Trustee.
<PAGE>   69

                                       - 63 -


                When the Trustee incurs expenses or renders services after an
         Event of Default specified in Section 5.1(4) occurs, the expenses and
         the compensation for the services are intended to constitute expenses
         of administration under the Bankruptcy Reform Act of 1978 or any
         successor statute.

                SECTION 6.8.   Disqualification; Conflicting Interests.

                The Trustee for the Securities of any series issued hereunder
         shall be subject to the provisions of Section 310(b) of the Trust
         Indenture Act. Nothing herein shall prevent the Trustee from filing
         with the Commission the application referred to in the second to last
         paragraph of said Section 310(b).

                SECTION 6.9.   Corporate Trustee Required; Eligibility.

                There shall at all times be a Trustee hereunder which shall be:

                (a) an entity organized and doing business under the laws of the
         United States of America or of any state or territory thereof or of the
         District of Columbia, authorized under such laws to exercise corporate
         trust powers and subject to supervision or examination by Federal,
         state, territorial or District of Columbia authority, or

                (b) an entity or other Person organized and doing business under
         the laws of a foreign government that is permitted to act as Trustee
         pursuant to a rule, regulation or order of the Commission, authorized
         under such laws to exercise corporate trust powers, and subject to
         supervision or examination by authority of such foreign government or a
         political subdivision thereof substantially equivalent to supervision
         or examination applicable to United States institutional trustees;

         in either case having a combined capital and surplus of at least
         $50,000,000, subject to supervision or examination by Federal or state
         authority. If such entity publishes reports of condition at least
         annually, pursuant to law or to the requirements of the aforesaid
         supervising or examining authority, then, for the purposes of this
         Section, the combined capital and surplus of such entity 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, it shall resign immediately in the manner and with the effect
         hereinafter specified in this Article. Neither the Company nor any
         Person directly or indirectly controlling, controlled by or under
         common control with the Company shall serve as Trustee for the
         Securities of any series issued hereunder.

                SECTION 6.10.  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 shall become effective
         until the acceptance of appointment by the successor Trustee under
         Section 6.11.

                (b) The Trustee may resign at any time with respect to the
         Securities of one or more series by giving written notice thereof to
         the Company. If an instrument of acceptance by a successor Trustee
         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 any series by Act of the Holders of a majority in
         aggregate 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 6.8 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
                6.9 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;

         then, in any such case, (i) the Company, acting pursuant to the
         authority of a Board Resolution, may remove the Trustee with respect to
         the Securities of all series issued hereunder, or (ii) subject to
         Section 5.14, any Holder who has been a bona fide Holder of a Security
         for at least six months may, on behalf of such Holder and all others
         similarly situated, petition any court of competent jurisdiction for
         the removal of the Trustee with respect to the Securities of all series
         issued hereunder 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 aggregate 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, become the successor Trustee with respect to the
         Securities of such series and supersede the successor Trustee 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 the manner hereinafter provided,
         any Holder who has been a bona fide Holder of a Security of such series
         for at least six months may, subject to Section 5.14, on behalf of such
         Holder 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.

                (f) The Company shall give notice of each resignation and each
         removal of the Trustee with respect to the Securities of any series and
         each appointment of a successor Trustee with respect to the Securities
         of any series by mailing written notice of such event by first-class
         mail, postage prepaid, to the Holders of Securities of such series as
         their names and addresses appear in the Securities Register. Each
         notice shall include the name of the successor Trustee with respect to
         the Securities of such series and the address of its Corporate Trust
         Office.

                SECTION 6.11.  Acceptance of Appointment by Successor.

                (a) In case of the appointment hereunder of a successor Trustee
         with respect to all Securities, every such successor Trustee so
         appointed shall execute, acknowledge and deliver to the Company and to
         the retiring Trustee an instrument accepting such appointment, and
         thereupon the resignation or removal of the retiring Trustee shall
         become effective and 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; but, on the request of the
         Company or the successor Trustee, such retiring Trustee shall, upon
         payment of its charges, 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.

                (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 retiring Trustee and each successor Trustee with respect
         to the Securities of one or more series shall execute and deliver an
         indenture supplemental hereto 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 or 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 removal of the retiring 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 hereunder with respect to the Securities of that
         or those series to which the appointment of such successor Trustee
         relates.

                (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 rights, powers
         and trusts referred to in paragraph (a) or (b) of this Section, as the
         case may be.

                (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 6.12.  Merger, Conversion, Consolidation or
                               Succession to Business.

                Any entity into which the Trustee may be merged or converted or
         with which it may be consolidated, or any entity resulting from any
         merger, conversion or consolidation to which the Trustee shall be a
         party, or any entity succeeding to all or substantially all of the
         corporate trust business of the Trustee, shall be the successor of the
         Trustee hereunder, provided such entity shall be otherwise qualified
         and eligible under this Article, 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, and in case
         any Securities shall not have been authenticated, any successor to the
         Trustee may authenticate such Securities either in the name of any
         predecessor Trustee or in the name of such successor Trustee, and in
         all cases the certificate of authentication shall have the full force
         which it is provided anywhere in the Securities or in this Indenture
         that the certificate of the Trustee shall have.

                SECTION 6.13.  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 6.14.  Appointment of Authenticating Agent.

                The Trustee may appoint an Authenticating Agent or Agents with
         respect to one or more series of Securities, which 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 thereof or pursuant to Section 3.6, 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 authentication and delivery on behalf of the
         Trustee by an Authenticating Agent. Each Authenticating Agent shall be
         acceptable to the Company and shall at all times be an entity organized
         and doing business under the laws of the United States of America, or
         of any state or territory thereof or of 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 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, such Authenticating Agent shall resign
         immediately in the manner and with the effect specified in this
         Section.

                Any entity into which an Authenticating Agent may be merged or
         converted or with which it may be consolidated, or any entity resulting
         from any merger, conversion or consolidation to which such
         Authenticating Agent shall be a party, or any entity succeeding to all
         or substantially all of the corporate trust business of an
         Authenticating Agent shall be the successor Authenticating Agent
         hereunder, provided such entity 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.

                An Authenticating Agent may resign at any time by giving written
         notice thereof to the Trustee and to the Company. The Trustee 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, the Trustee
         may appoint a successor Authenticating Agent, which shall be acceptable
         to the Company and shall give notice of such appointment in the manner
         provided in Section 1.6 to all Holders of Securities of the series with
         respect to which such Authenticating Agent will serve. Any successor
         Authenticating Agent upon acceptance 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 provision of this Section.

                The Company agrees to pay to each Authenticating Agent from time
         to time reasonable compensation for its services under this Section,
         and the Trustee shall be entitled to be reimbursed for such payment,
         subject to the provisions of Section 6.7.

                If an appointment with respect to one or more series is made
         pursuant to this Section, the Securities of such series may

         authentication, an alternative certificate of authentication in the

                Officers' Certificate and an Opinion of Counsel, each stating
                that such consolidation, merger, conveyance, transfer or lease
                and any such supplemental indenture comply with this Article and
                that all conditions precedent herein provided for relating to
                such transaction have been complied with and, in the case of a
                transaction subject to this Section 8.1 but not requiring a
                supplemental indenture under paragraph (1) of this Section 8.1,
                an Officer's Certificate or Opinion of Counsel to the effect
                that the surviving, resulting or successor entity is legally
                bound by the Indenture and the Securities; and the Trustee,
                subject to Section 6.1, may rely upon such Officers'
                Certificates and Opinions of Counsel as conclusive evidence that
                such transaction complies with this Section 8.1.

                SECTION 8.2.   Successor Company Substituted.

                Upon any consolidation or merger by the Company with or into any
         other Person, or any conveyance, transfer or lease by the Company of
         its properties and assets substantially as an entirety to any Person in
         accordance with Section 8.1, the successor entity formed by such
         consolidation or into which the Company is merged or to which such
         conveyance, transfer or lease is made shall succeed to, and be
         substituted for, and may exercise every right and power of, the Company
         under this Indenture with the same effect as if such successor Person
         had been named as the Company herein; and in the event of any such
         conveyance, transfer or lease the Company shall be discharged from all
         obligations and covenants under the Indenture and the Securities.

                Such successor Person may cause to be executed, and may issue
         either in its own name or in the name of the Company, any or all of the
         Securities issuable hereunder that theretofore shall not have been
         signed by the Company and delivered to the Trustee; and, upon the order
         of such successor Person instead of the Company and subject to all the
         terms, conditions and limitations in this Indenture prescribed, the
         Trustee shall authenticate and shall deliver any Securities that
         previously shall have been signed and delivered by the officers of the
         Company to the Trustee for authentication pursuant to such provisions
         and any Securities that such successor Person thereafter shall cause to
         be executed and delivered to the Trustee on its behalf for the purpose
         pursuant to such provisions. All the Securities so issued shall in all
         respects have the same legal rank and benefit under this Indenture as
         the Securities theretofore or thereafter issued in accordance with the
         terms of this Indenture.

                In case of any such consolidation, merger, sale, conveyance or
         lease, such changes in phraseology and form may be made in the
         Securities thereafter to be issued as may be appropriate.

         that is entitled to the benefit of such provision or (b) not apply to
         any Outstanding Securities; or

                (8) to cure any ambiguity, to correct or supplement any
         provision herein that may be defective or inconsistent with any other
         provision herein, or to make any other provisions with respect to
         matters or questions arising under this Indenture, provided that such
         action pursuant to this clause (8) shall not adversely affect the
         interest of the Holders of Securities of any series in any material
         respect or, in the case of the Securities of a series issued to an
         Issuer Trust and for so long as any of the corresponding series of
         Capital Securities issued by such Issuer Trust shall remain
         outstanding, the holders of such Capital Securities; or

                (9) to evidence and provide for the acceptance of appointment
         hereunder by a successor Trustee with respect to the Securities of one
         or more series and to add to or change any of the provisions of this

                SECTION 9.2.   Supplemental Indentures with Consent of
                               Holders.

                With the consent of the Holders of not less than a majority in
         aggregate principal amount of the Outstanding Securities of each series
         affected by such supplemental indenture, by Act of said Holders
         delivered to the Company and the Trustee, the Company, when authorized
         by a Board Resolution, and the Trustee may enter into an indenture or
         indentures supplemental hereto for the purpose of adding any provisions
         to or changing in any manner or eliminating any of the provisions of
         this Indenture or of modifying in any manner the rights of the Holders
         of Securities of such series under this Indenture; provided, however,
         that no such supplemental indenture shall, without the consent of the
         Holder of each Outstanding Security of each series affected thereby,

                     (1) change the Stated Maturity of the principal of, or any
                installment of interest (including any Additional Interest) on,

                change the place of payment where, or the coin or currency in
                which, any Security or interest thereon is payable, or impair
                the right to institute suit for the enforcement of any such

                                       - 75 -


                payment on or after the Stated Maturity thereof (or, in the
                case of redemption, on or after the Redemption Date), or

                     (2) reduce the percentage in aggregate 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 (of
                compliance with certain provisions of this Indenture or certain
                defaults hereunder and their consequences) provided for in this
                Indenture, or

                cannot be modified or waived without the consent of the Holder
                of each Security affected thereby;

                provided, further, that, in the case of the Securities of a
                series issued to an Issuer Trust, so long as any of the
                corresponding series of Capital Securities issued by such Issuer
                Trust remains outstanding, (i) no such amendment shall be made
                that adversely affects the holders of such Capital Securities in
                any material respect, and no termination of this Indenture shall
                occur, and no waiver of any Event of Default or compliance with
                any covenant under this Indenture shall be effective, without
                the prior consent of the holders of at least a majority of the
                aggregate Liquidation Amount (as defined in the related Trust
                Agreement) of such Capital Securities then outstanding unless
                and until the principal of (and premium, if any, on) the
                Securities of such series and all accrued and (subject to
                Section 3.8) unpaid interest (including any Additional Interest)
                thereon have been paid in full, and (ii) no amendment shall be
                made to Section 5.8 of this Indenture that would impair the
                rights of the holders of Capital Securities issued by an Issuer
                Trust provided therein without the prior consent of the holders
                of each such Capital Security then outstanding unless and until
                the principal of (and premium, if any, on) the Securities of
                such series and all accrued and (subject to Section 3.8) unpaid
                interest (including any Additional Interest) thereon have been
                paid in full.

                A supplemental indenture that changes or eliminates any covenant
         or other provision of this Indenture that has expressly been included
         solely for the benefit of one or more particular series of Securities
         or any corresponding series of Capital Securities of an Issuer Trust
         that holds the Securities of any series, or that modifies the rights of
         the Holders of Securities of such series or holders of such Capital
         Securities of such corresponding series with respect to such covenant
         or other
<PAGE>   82

                                       - 76 -


         provision, shall be deemed not to affect the rights under this
         Indenture of the Holders of Securities of any other series or holders
         of Capital Securities of any other such corresponding series.

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

                SECTION 9.3.   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 6.1) shall be fully
         protected in relying upon, an Officers' Certificate and an Opinion of
         Counsel stating that the execution of such supplemental indenture is
         authorized or permitted by this Indenture, and that all conditions
         precedent herein provided for relating to such action have been
         complied with. 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 9.4.   Effect of Supplemental Indentures.

                Upon the execution of any supplemental indenture under this
         Article, 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.

                SECTION 9.5.   Conformity with Trust Indenture Act.

                Every supplemental indenture executed pursuant to this Article
         shall conform to the requirements of the Trust Indenture Act as then in
         effect.

                SECTION 9.6.   Reference in Securities to Supplemental
                               Indentures.

                Securities authenticated and delivered after the execution of
         any supplemental indenture pursuant to this Article may, and shall if
         required by the Company, bear a notation in form approved by the
         Company 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 Company, to any such
         supplemental indenture may be prepared and
<PAGE>   83

                                       - 77 -


         executed by the Company and authenticated and delivered by the Trustee
         in exchange for Outstanding Securities of such series.


                                    ARTICLE X
                                    COVENANTS

                SECTION 10.1.  Payment of Principal, Premium and Interest.

                The Company covenants and agrees for the benefit of each series
         of Securities that it will duly and punctually pay the principal of
         (and premium, if any) and interest (including any Additional Interest)
         on the Securities of that series in accordance with the terms of such
         Securities and this Indenture.

                SECTION 10.2.  Maintenance of Office or Agency.

                The Company will maintain in each Place of Payment for any
         series of Securities an office or agency where Securities of that
         series may be presented or surrendered for payment, where Securities of
         that 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 that series and this Indenture may be served. The Company
         initially appoints the Trustee, acting through its Corporate Trust
         Office, as its agent for said purposes. The Company will give prompt
         written notice to the Trustee of any change in the location of any such
         office or agency. If at any time the Company shall fail to maintain
         such 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.

                The Company may also from time to time designate one or more
         other offices or agencies where the Securities may be presented or
         surrendered for any or all of such purposes, and may from time to time
         rescind such designations; provided, however, that no such designation
         or rescission shall in any manner relieve the Company of its obligation
         to maintain an office or agency in each Place of Payment for Securities
         of any series for such purposes. The Company will give prompt written
         notice to the Trustee of any such designation and any change in the
         location of any such office or agency.

                SECTION 10.3.  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 Securities, it will, on or before each
         due date of the principal of (and premium, if any) or interest
         (including Additional Interest) on any of the Securities of such
         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 (including Additional Interest) so becoming due until
         such sums shall be paid to such Persons or otherwise disposed of as
         herein provided, and will promptly notify the Trustee of its failure so
         to act.

                Whenever the Company shall have one or more Paying Agents, it
         will, prior to 10:00 a.m., New York City time, on each due date of the
         principal of (or premium, if any) or interest, including Additional
         Interest on any Securities, deposit with a Paying Agent a sum
         sufficient to pay the principal (and premium, if any) or interest,
         including Additional Interest so becoming due, such sum to be held in
         trust for the benefit of the Persons entitled to such principal (and
         premium, if any) or interest, including Additional Interest, and
         (unless such Paying Agent is the Trustee) the Company will promptly
         notify the Trustee of its failure so to act.

                The Company will 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, that such Paying Agent will:

                (1) hold all sums held by it for the payment of the principal of
         (and premium, if any, or interest (including Additional Interest) on
         the Securities of a series in trust for the benefit of the Persons
         entitled thereto until such sums shall be paid to such Persons or
         otherwise disposed of as herein provided;

                (2) give the Trustee notice of any default by the Company (or
         any other obligor upon such Securities) in the making of any payment of
         principal (and premium, if any) or interest (or Additional Interest) in
         respect of any Security of any Series;

                (3) at any time during the continuance of any default with
         respect to a series of Securities, upon the written request of the
         Trustee, forthwith pay to the Trustee all sums so held in trust by such
         Paying Agent with respect to such series; and
<PAGE>   85

                                       - 79 -


                (4) comply with the provisions of the Trust Indenture Act
         applicable to it as a Paying Agent.

                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.

                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 (including Additional Interest) on
         any Security and remaining unclaimed for two years after such principal
         (and premium, if any) or interest (including Additional Interest) has
         become due and payable shall (unless otherwise required by mandatory
         provision of applicable escheat or abandoned or unclaimed property law)
         be paid on Company Request to the Company, or (if then held by the
         Company) shall (unless otherwise required by mandatory provision of
         applicable escheat or abandoned or unclaimed property law) 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, and all liability of the
         Company as trustee thereof, shall thereupon cease; provided, however,
         that the Trustee or such Paying Agent, before being required to make

                The Company shall deliver to the Trustee, within 120 days after

         without regard to any grace period or requirement of notice provided

                SECTION 10.5.  Waiver of Certain Covenants.

                Subject to the rights of holders of Capital Securities specified

         to comply with any covenant or condition provided pursuant to Section
         3.1, 9.1(3) or 9.1(4) with respect to the Securities of any series, if
         before or after the time for such compliance the Holders of at least a
         majority in aggregate principal amount 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 in
         respect of any such covenant or condition shall remain in full force
         and effect.

                SECTION 10.6.  Additional Sums.

                In the case of the Securities of a series initially issued to an
         Issuer Trust, so long as no Event of Default has occurred and is
         continuing and except as otherwise specified as contemplated by Section
         2.1 or Section 3.1, if (i) an Issuer Trust is the Holder of all of the
         Outstanding Securities of such series, and (ii) a Tax Event described
         in clause (i) or (iii) of the definition of "Tax Event" in Section 1.1
         hereof has occurred and is continuing in respect of such Issuer Trust,
         the Company shall pay to such Issuer Trust (and its permitted
         successors or assigns under the related Trust Agreement) for so long as
         such Issuer Trust (or its permitted successor or assignee) is the
         registered holder of the Outstanding Securities of such series, such
         additional sums as may be necessary in order that the amount of
         Distributions (including any Additional Amounts (as defined in such
         Trust Agreement)) then due and payable by such Issuer Trust on the
         related Capital Securities and Common Securities that at any time
         remain outstanding in accordance with the terms thereof shall not be
         reduced as a result of such Additional Taxes (the "Additional Sums").
         Whenever in this Indenture or the Securities there is a reference in
         any context to the payment of principal of or interest on the
         Securities, such mention shall be deemed to include mention of the
         payments of the Additional Sums provided for in this paragraph to the
         extent that, in such context, Additional Sums are, were or would be
         payable in respect thereof pursuant to the provisions of this paragraph
         and express mention of the payment of Additional Sums (if applicable)
         in any provisions hereof shall not be construed as excluding Additional
         Sums in those provisions hereof where such express mention is not made;
         provided, however, that the deferral of the payment of
<PAGE>   87

                                       - 81 -


         interest pursuant to Section 3.12 or the Securities shall not defer the
         payment of any Additional Sums that may be due and payable.

                SECTION 10.7.  Additional Covenants.

                The Company covenants and agrees with each Holder of Securities
         of each series that it shall not (x) declare or pay any dividends or
         distributions on, or redeem purchase, acquire or make a liquidation
         payment with respect to, any shares of the Company's capital stock, or
         (y) make any payment of principal of or interest or premium, if any, on
         or repay, repurchase or redeem any debt securities of the Company that
         rank pari passu in all respects with or junior in interest to the
         Securities of such series (other than (a) repurchases, redemptions or
         other acquisitions of shares of capital stock of the Company in
         connection with any employment contract, benefit plan or other similar
         arrangement with or for the benefit of any one or more employees,
         officers, directors or consultants, in connection with a dividend
         reinvestment or stockholder stock purchase plan or in connection with
         the issuance of capital stock of the Company (or securities convertible
         into or exercisable for such capital stock) as consideration in an
         acquisition transaction entered into prior to the applicable Extension
         Period or other event referred to below, (b) as a result of an exchange
         or conversion of any class or series of the Company's capital stock (or
         any capital stock of a Subsidiary of the Company) for any class or
         series of the Company's capital stock or of any class or series of the
         Company's indebtedness for any class or series of the Company's capital
         stock, (c) the purchase of fractional interests in shares of the
         Company's capital stock pursuant to the conversion or exchange
         provisions of such capital stock or the security being converted or
         exchanged, (d) any declaration of a dividend in connection with any
         Rights Plan, or the issuance of rights, stock or other property under
         any Rights Plan, or the redemption or repurchase of rights pursuant
         thereto, or (e) any dividend in the form of stock, warrants, options or
         other rights where the dividend stock or the stock issuable upon
         exercise of such warrants, options or other rights is the same stock as
         that on which the dividend is being paid or ranks pari passu with or
         junior to such stock) if at such time (i) there shall have occurred any
         event (A) of which the Company has actual knowledge that with the
         giving of notice or the lapse of time, or both, would constitute an
         Event of Default with respect to the Securities of such series, and (B)
         which the Company shall not have taken reasonable steps to cure, (ii)
         if the Securities of such series are held by an Issuer Trust, the
         Company shall be in default with respect to its payment of any
         obligations under the Guarantee relating to the Capital Securities
         issued by such Issuer Trust, or (iii) the Company shall have given
         notice of its election to begin an Extension Period with respect to the
         Securities of such series as provided herein and shall not have

         rescinded such notice, or such Extension Period, or any extension
         thereof, shall be continuing.

                The Company also covenants with each Holder of Securities of a
         series issued to an Issuer Trust (i) to hold, directly or indirectly,
         100% of the Common Securities of such Issuer Trust, provided that any
         permitted successor of the Company as provided under Section 8.2 may
         succeed to the Company's ownership of such Common Securities, (ii) as
         holder of such Common Securities, not to voluntarily terminate, windup
         or liquidate such Issuer Trust, other than (a) in connection with a
         distribution of the Securities of such series to the holders of the
         related Capital Securities in liquidation of such Issuer Trust, or (b)
         in connection with certain mergers, consolidations or amalgamations
         permitted by the related Trust Agreement, and (iii) to use its
         reasonable efforts, consistent with the terms and provisions of such
         Trust Agreement, to cause such Issuer Trust to continue not to be
         taxable as a corporation for United States Federal income tax purposes.

                SECTION 10.8.  Original Issue Discount.

                On or before December 15 of each year during which any
         Securities are outstanding, the Company shall furnish to each Paying
         Agent such information as may be reasonably requested by each Paying
         Agent in order that each Paying Agent may prepare the information which
         it is required to report for such year on Internal Revenue Service
         Forms 1096 and 1099 pursuant to Section 6049 of the Internal Revenue
         Code of 1986, as amended. Such information shall include the amount of
         original issue discount includible in income for each authorized
         minimum denomination of principal amount at Stated Maturity of
         outstanding Securities during such year.


                                   ARTICLE XI
                            REDEMPTION OF SECURITIES

                SECTION 11.1.  Applicability of This Article.

                Redemption of Securities of any series as permitted or required
         by any form of Security issued pursuant to this Indenture shall be made
         in accordance with such form of Security and this Article; provided,
         however, that, if any provision of any such form of Security shall
         conflict with any provision of this Article, the provision of such form
         of Security shall govern.

                SECTION 11.2.  Election to Redeem; Notice to Trustee.

                The election of the Company to redeem any Securities shall be
         evidenced by or pursuant to a Board Resolution. In case of any
         redemption at the election of the Company, the Company shall, not
<PAGE>   89

                                       - 83 -


         less than 30 nor more than 60 days prior to the Redemption Date (unless
         a shorter notice shall be satisfactory to the Trustee), notify the
         Trustee and, in the case of Securities of a series held by an Issuer
         Trust, the Property Trustee under the related Trust Agreement, of such
         date and of the principal amount of Securities of the applicable series
         to be redeemed and provide the additional information required to be
         included in the notice or notices contemplated by Section 11.4;
         provided that, in the case of any series of Securities initially issued
         to an Issuer Trust, for so long as such Securities are held by such
         Issuer Trust, such notice shall be given not less than 45 nor more than
         75 days prior to such Redemption Date (unless a shorter notice shall be
         satisfactory to the Property Trustee under the related Trust
         Agreement). In the case of any redemption of Securities prior to the
         expiration of any restriction on such redemption provided in the terms
         of such Securities, the Company shall furnish the Trustee with an
         Officers' Certificate and an Opinion of Counsel evidencing compliance
         with such restriction.

                SECTION 11.3.  Selection of Securities to be Redeemed.

                If less than all the Securities of any series are to be
         redeemed, the particular Securities to be redeemed shall be selected
         not more than 60 days prior to the Redemption Date by the Trustee, from
         the Outstanding Securities of such series not previously called for
         redemption, by such method as the Trustee shall deem fair and
         appropriate and which may provide for the selection for redemption of a
         portion of the principal amount of any Security of such series,
         provided that the unredeemed portion of the principal amount of any
         Security shall be in an authorized denomination (which shall not be
         less than the minimum authorized denomination) for such Security.

                The Trustee shall promptly notify the Company in writing of the
         Securities selected for partial redemption and the principal amount
         thereof to be redeemed. For all purposes of this Indenture, unless the
         context otherwise requires, all provisions relating to the redemption
         of Securities shall relate, in the case of any Security redeemed or to
         be redeemed only in part, to the portion of the principal amount of
         such Security that has been or is to be redeemed.

                SECTION 11.4.  Notice of Redemption.

                Notice of redemption shall be given by first-class mail, postage
         prepaid, mailed not later than the thirtieth day, and not earlier than

         Securities to be redeemed, at the address of such Holder as it appears
         in the Securities Register.
<PAGE>   90

                                       - 84 -


                With respect to Securities of such series to be redeemed, each
         notice of redemption shall state:

                (a)  the Redemption Date;

                (b) the Redemption Price or, if the Redemption Price cannot be
         calculated prior to the time the notice is required to be sent, the
         estimate of the Redemption Price provided pursuant to the Indenture
         together with a statement that it is an estimate and that the actual
         Redemption Price will be calculated on the third Business Day prior to
         the Redemption Date (if such an estimate of the Redemption Price is
         given, a subsequent notice shall be given as set forth above setting
         forth the Redemption Price promptly following the calculation thereof);

                (c) if less than all Outstanding Securities of such particular
         series are to be redeemed, the identification (and, in the case of
         partial redemption, the respective principal amounts) of the particular
         Securities to be redeemed;

                (d) that, on the Redemption Date, the Redemption Price will
         become due and payable upon each such Security or portion thereof, and
         that interest thereon, if any, shall cease to accrue on and after said
         date;

                (e)  the place or places where such Securities are to be
         surrendered for payment of the Redemption Price;

                (f)  such other provisions as may be required in respect of
         the terms of a particular series of Securities; and

                (g)  that the redemption is for a sinking fund, if such is
         the case.

                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. The notice, if mailed in the manner
         provided above, shall be conclusively presumed to have been duly given,
         whether or not the Holder receives such notice. In any case, a failure
         to give such notice by mail or any defect in the notice to the Holder
         of any Security designated for redemption as a whole or in part shall
         not affect the validity of the proceedings for the redemption of any
         other Security.

                SECTION 11.5.  Deposit of Redemption Price.

                Prior to 10:00 a.m., New York City time, on the Redemption Date
         specified in the notice of redemption given as provided in Section
         11.4, the Company will deposit with the Trustee or with one or more
         Paying Agents (or if the Company is acting as its own
<PAGE>   91

                                       - 85 -


         Paying Agent, the Company will segregate and hold in trust as provided
         in Section 10.3) an amount of money sufficient to pay the Redemption
         Price of, and any accrued interest (including Additional Interest) on,
         all the Securities (or portions thereof) that are to be redeemed on
         that date.

                SECTION 11.6.  Payment of Securities Called for Redemption.

                If any notice of redemption has been given as provided in
         Section 11.4, the Securities or portion of Securities with respect to
         which such notice has been given shall become due and payable on the
         date and at the place or places stated in such notice at the applicable
         Redemption Price, together with accrued interest (including any
         Additional Interest) to the Redemption Date. On presentation and
         surrender of such Securities at a Place of Payment in said notice
         specified, the said Securities or the specified portions thereof shall
         be paid and redeemed by the Company at the applicable Redemption Price,
         together with accrued interest (including any Additional Interest) to
         the Redemption Date; provided, however, that, unless otherwise
         specified as contemplated by Section 3.1, installments of interest
         (including Additional Interest) whose Stated Maturity is on or prior to
         the Redemption Date will 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 3.8.

                Upon presentation of any Security redeemed in part only, the
         Company shall execute and the Trustee shall authenticate and deliver to
         the Holder thereof, at the expense of the Company, a new Security or
         Securities of the same series, of authorized denominations, in
         aggregate principal amount equal to the unredeemed portion of the
         Security so presented and having the same Original Issue Date, Stated
         Maturity and terms.

                If any Security called for redemption shall not be so paid under
         surrender thereof for redemption, the principal of and premium, if any,
         on such Security shall, until paid, bear interest from the Redemption
         Date at the rate prescribed therefor in the Security.

                SECTION 11.7.  Right of Redemption of Securities Initially
                               Issued to an Issuer Trust.

                In the case of the Securities of a series initially issued to an
         Issuer Trust, except as otherwise specified as contemplated by Section
         3.1, the Company, at its option, may redeem such Securities (i) on or
         after the date specified in such Security, in whole at any time or in
         part from time to time, or (ii) upon the occurrence and during the
         continuation of a Tax Event, an Investment Company Event or a Capital
         Treatment Event, at any time
<PAGE>   92

                                       - 86 -


   
         within 90 days following the occurrence and during the continuation of
         such Tax Event, Investment Company Event or Capital Treatment Event
         provided (if so specified in the securities of the series pursuant to
         Section 3.1(g)) that none of the Company's 8.75% Subordinated Notes Due
         January 31, 2000 remain outstanding at the time of any redemption -
         pursuant to clause (ii) of this Section 11.7, in whole (but not in
         part), in each case at a Redemption Price specified in such Security,
         together with accrued interest (including Additional Interest) to the
         Redemption Date.
    

                If less than all the Securities of any such series are to be
         redeemed, the aggregate principal amount of such Securities remaining
         Outstanding after giving effect to such redemption shall be sufficient
         to satisfy any provisions of the Trust Agreement related to the Issuer
         Trust to which such Securities were issued.


                                   ARTICLE XII
                                  SINKING FUNDS

                Except as may be provided in any supplemental or amended
         indenture, no sinking fund shall be established or maintained for the
         retirement of Securities of any series.

                The Company covenants and agrees, and each Holder of a Security,
         by its acceptance thereof, likewise covenants and agrees, that, to the
         extent and in the manner hereinafter set forth in this Article, the
         payment of the principal of (and premium, if any) and interest
         (including any Additional Interest) on each and all of the Securities
         of each and every series are hereby expressly made subordinate and
         subject in right of payment to the prior payment in full of all Senior
         Indebtedness.

                SECTION 13.2.  No Payment When Senior Indebtedness in
                               Default; Payment Over of Proceeds Upon

                If the Company shall default in the payment of any principal of
         (or premium, if any) or interest on any Senior Indebtedness when the
         same becomes due and payable, whether at maturity or at a date fixed
         for prepayment or by declaration of acceleration or otherwise, then,
         upon written notice of such default to the Company by the holders of
         Senior Indebtedness or any trustee therefor, unless and until such
         default shall have been cured or waived or shall have ceased to exist,

         set-off or otherwise) shall be made or agreed to be made on account of

         repayment, retirement, purchase or other acquisition of any of the
         Securities.

                In the event of (i) any insolvency, bankruptcy, receivership,
         liquidation, reorganization, readjustment, composition or other similar
         proceeding relating to the Company, its creditors or its property, (ii)
         any proceeding for the liquidation, dissolution or other winding up of
         the Company, voluntary or involuntary, whether or not involving
         insolvency or bankruptcy proceedings, (iii) any assignment by the
         Company for the benefit of creditors or (iv) any other marshalling of
         the assets of the Company (each such event, if any, herein sometimes
         referred to as a "Proceeding"), all Senior Indebtedness (including any
         interest thereon accruing after the commencement of any such
         proceedings) shall first be paid in full before any payment or
         distribution, whether in cash, securities or other property, shall be
         made to any Holder of any of the Securities on account thereof. Any
         payment or distribution, whether in cash, securities or other property
         (other than securities of the Company or any other entity provided for
         by a plan of reorganization or readjustment, the payment of which is
         subordinate, at least to the extent provided in these subordination
         provisions with respect to the indebtedness evidenced by the
         Securities, to the payment of all Senior Indebtedness at the time
         outstanding and to any securities issued in respect thereof under any
         such plan of reorganization or readjustment), which would otherwise
         (but for these subordination provisions) be payable or deliverable in
         respect of the Securities of any series shall be paid or delivered
         directly to the holders of Senior Indebtedness in accordance with the
         priorities then existing among such holders until all Senior
         Indebtedness (including any interest thereon accruing after the
         commencement of any Proceeding) shall have been paid in full.

                In the event of any Proceeding, after payment in full of all
         sums owing with respect to Senior Indebtedness, the Holders of the
         Securities, together with the holders of any obligations of the Company
         ranking on a parity with the Securities, shall be entitled to be paid
         from the remaining assets of the Company the amounts at the time due
         and owing on account of unpaid principal of (and premium, if any) and
         interest on the Securities and such other obligations before any
         payment or other distribution, whether in cash, property or otherwise,
         shall be made on account of any capital stock or any obligations of the
         Company ranking junior to the Securities, and such other obligations.
         If, notwithstanding the foregoing, any payment or distribution of any
         character or any security, whether in cash, securities or other
         property (other than securities of the Company or any other entity
         provided for by a plan of reorganization or readjustment the payment of
         which is subordinate, at least to the extent provided
<PAGE>   94

                                       - 88 -


         in these subordination provisions with respect to the indebtedness
         evidenced by the Securities, to the payment of all Senior Indebtedness
         at the time outstanding and to any securities issued in respect thereof
         under any plan of reorganization or readjustment), shall be received by
         the Trustee or any Holder in contravention of any of the terms hereof
         and before all Senior Indebtedness shall have been paid in full, such
         payment or distribution or security shall be received in trust for the
         benefit of, and shall be paid over or delivered and transferred to, the
         holders of the Senior Indebtedness at the time outstanding in
         accordance with the priorities then existing among such holders for
         application to the payment of all Senior Indebtedness remaining unpaid,
         to the extent necessary to pay all such Senior Indebtedness in full. In
         the event of the failure of the Trustee or any Holder to endorse or
         assign any such payment, distribution or security, each holder of
         Senior Indebtedness is hereby irrevocably authorized to endorse or
         assign the same.

                The Trustee and the Holders shall take such action (including,
         without limitation, the delivery of this Indenture to an agent for the
         holders of Senior Indebtedness or consent to the filing of a financing
         statement with respect hereto) as may, in the opinion of counsel
         designated by the holders of a majority in principal amount of the
         Senior Indebtedness at the time outstanding, be necessary or
         appropriate to assure the effectiveness of the subordination effected
         by these provisions.

                The provisions of this Section 13.2 shall not impair any rights,
         interests, remedies or powers of any secured creditor of the Company in
         respect of any security interest the creation of which is not
         prohibited by the provisions of this Indenture.

                The securing of any obligations of the Company, otherwise
         ranking on a parity with the Securities or ranking junior to the
         Securities shall not be deemed to prevent such obligations from
         constituting, respectively, obligations ranking on a parity with the
         Securities or ranking junior to the Securities.

                SECTION 13.3.  Payment Permitted If No Default.

                Nothing contained in this Article or elsewhere in this Indenture
         or in any of the Securities shall prevent (a) the Company, at any time,
         except during the pendency of the conditions described in the first
         paragraph of Section 13.2 or of any Proceeding referred to in Section
         13.2, from making payments at any time of principal of (and premium, if
         any) or interest (including Additional Interest) on the Securities, or
         (b) the application by the Trustee of any monies deposited with it
         hereunder to the payment of or on account of the principal of (and
         premium, if any) or interest (including any Additional Interest) on the
         Securities or the retention of such payment by the Holders,
<PAGE>   95

                                       - 89 -


         if, at the time of such application by the Trustee, it did not have
         knowledge that such payment would have been prohibited by the
         provisions of this Article.

                SECTION 13.4.  Subrogation to Rights of Holders of Senior
                               Indebtedness.

                Subject to the payment in full of all amounts due or to become
         due on all Senior Indebtedness, or the provision for such payment in
         cash or cash equivalents or otherwise in a manner satisfactory to the
         holders of Senior Indebtedness, the Holders of the Securities shall be
         subrogated to the extent of the payments or distributions made to the
         holders of such Senior Indebtedness pursuant to the provisions of this
         Article (equally and ratably with the holders of all indebtedness of
         the Company that by its express terms is subordinated to Senior
         Indebtedness of the Company to substantially the same extent as the
         Securities are subordinated to the Senior Indebtedness and is entitled
         to like rights of subrogation by reason of any payments or
         distributions made to holders of such Senior Indebtedness) to the
         rights of the holders of such Senior Indebtedness to receive payments
         and distributions of cash, property and securities applicable to the
         Senior Indebtedness until the principal of (and premium if any) and
         interest (including Additional Interest) on the Securities shall be
         paid in full. For purposes of such subrogation, no payments or
         distributions to the holders of the Senior Indebtedness of any cash,
         property or securities to which the Holders of the Securities or the
         Trustee would be entitled except for the provisions of this Article,
         and no payments over pursuant to the provisions of this Article to the
         holders of Senior Indebtedness by Holders of the Securities or the
         Trustee, shall, as among the Company, its creditors other than holders
         of Senior Indebtedness, and the Holders of the Securities, be deemed to
         be a payment or distribution by the Company to or on account of the
         Senior Indebtedness.

                SECTION 13.5.  Provisions Solely to Define Relative Rights.

                The provisions of this Article are and are intended solely for
         the purpose of defining the relative rights of the Holders of the
         Securities on the one hand and the holders of Senior Indebtedness on
         the other hand. Nothing contained in this Article or elsewhere in this
         Indenture or in the Securities is intended to or shall (a) impair, as
         between the Company and the Holders of the Securities, the obligations
         of the Company, which are absolute and unconditional, to pay to the
         Holders of the Securities the principal of (and premium, if any) and
         interest (including any Additional Interest) on the Securities as and
         when the same shall become due and payable in accordance with their
         terms; or (b) affect the relative rights against the Company of the
         Holders of the Securities and creditors of the Company other than their
<PAGE>   96

                                       - 90 -


         rights in relation to the holders of Senior Indebtedness; or (c)
         prevent the Trustee or the Holder of any Security (or to the extent
         expressly provided herein, the holder of any Capital Security) from
         exercising all remedies otherwise permitted by applicable law upon
         default under this Indenture, including filing and voting claims in any
         Proceeding, subject to the rights, if any, under this Article of the
         holders of Senior Indebtedness to receive cash, property and securities
         otherwise payable or deliverable to the Trustee or such Holder.

                SECTION 13.6.  Trustee to Effectuate Subordination.

                Each Holder of a Security by his or her acceptance thereof
         authorizes and directs the Trustee on his or her behalf to take such
         action as may be necessary or appropriate to acknowledge or effectuate
         the subordination provided in this Article and appoints the Trustee his
         or her attorney-in-fact for any and all such purposes.

                SECTION 13.7.  No Waiver of Subordination Provisions.

                No right of any present or future holder of any Senior
         Indebtedness to enforce subordination as herein provided shall at any
         time in any way be prejudiced or impaired by any act or failure to act
         on the part of the Company or by any act or failure to act, in good
         faith, by any such holder, or by any noncompliance by the Company with
         the terms, provisions and covenants of this Indenture, regardless of
         any knowledge thereof that any such holder may have or be otherwise
         charged with.

                Without in any way limiting the generality of the immediately
         preceding paragraph, the holders of Senior Indebtedness may, at any
         time and from time to time, without the consent of or notice to the
         Trustee or the Holders of the Securities of any series, without
         incurring responsibility to such Holders of the Securities and without
         impairing or releasing the subordination provided in this Article or
         the obligations hereunder of such Holders of the Securities to the
         holders of Senior Indebtedness, do any one or more of the following:
         (i) change the manner, place or terms of payment or extent the time of
         payment of, or renew or alter, Senior Indebtedness, or otherwise amend
         or supplement in any manner Senior Indebtedness or any instrument
         evidencing the same or any agreement under which Senior Indebtedness is
         outstanding; (ii) sell, exchange, release or otherwise deal with any
         property pledged, mortgaged or otherwise securing Senior Indebtedness;
         (iii) release any Person liable in any manner for the collection of
         Senior Indebtedness; and (iv) exercise or refrain from exercising any
         rights against the Company and any other Person.

                SECTION 13.8.  Notice to Trustee.

                The Company shall give prompt written notice to a Responsible
         Officer of the Trustee of any fact known to the Company that would
         prohibit the making of any payment to or by the Trustee in respect of
         the Securities. Notwithstanding the provisions of this Article or any
         other provision of this Indenture, the Trustee shall not be charged
         with knowledge of the existence of any facts that would prohibit the
         making of any payment to or by the Trustee in respect of the
         Securities, unless and until the Trustee shall have received written
         notice thereof from the Company or a holder of Senior Indebtedness or
         from any trustee, agent or representative therefor; provided, however,
         that if the Trustee shall not have received the notice provided for in
         this Section at least two Business Days prior to the date upon which by
         the terms hereof any monies may become payable for any purpose
         (including, the payment of the principal of (and premium, if any, on)
         or interest (including any Additional Interest) on any Security), then,
         anything herein contained to the contrary notwithstanding, the Trustee
         shall have full power and authority to receive such monies and to apply
         the same to the purpose for which they were received and shall not be
         affected by any notice to the contrary that may be received by it
         within two Business Days prior to such date.

                Subject to the provisions of Section 6.1, the Trustee shall be
         entitled to rely on the delivery to it of a written notice by a Person
         representing himself or herself to be a holder of Senior Indebtedness
         (or a trustee or attorney-in-fact therefor) to establish that such
         notice has been given by a holder of Senior Indebtedness (or a trustee
         or attorney-in-fact therefor). In the event that the Trustee determines
         in good faith that further evidence is required with respect to the
         right of any Person as a holder of Senior Indebtedness to participate
         in any payment or distribution pursuant to this Article, the Trustee
         may request such Person to furnish evidence to the reasonable
         satisfaction of the Trustee as to the amount of Senior Indebtedness
         held by such Person, the extent to which such Person is entitled to
         participate in such payment or distribution and any other facts
         pertinent to the rights of such Person under this Article, and if such
         evidence is not furnished, the Trustee may defer any payment to such
         Person pending judicial determination as to the right of such Person to
         receive such payment.

                SECTION 13.9.  Reliance on Judicial Order or Certificate of
                               Liquidating Agent.

                Upon any payment or distribution of assets of the Company
         referred to in this Article, the Trustee, subject to the provisions of
         Section 6.1, and the Holders of the Securities shall be entitled to
         rely upon any order or decree entered by any court
<PAGE>   98

                                       - 92 -


         of competent jurisdiction in which such Proceeding is pending, or a
         certificate of the trustee in bankruptcy, receiver, conservator,
         liquidating trustee, custodian, assignee for the benefit of creditors,
         agent or other Person making such payment or distribution, delivered to
         the Trustee or to the Holders of Securities, for the purpose of
         ascertaining the Persons entitled to participate in such payment or
         distribution, the holders of the Senior Indebtedness and other
         indebtedness of the Company, the amount thereof or payable thereon, the
         amount or amounts paid or distributed thereon and all other facts
         pertinent thereto or to this Article.

                SECTION 13.10. Trustee Not Fiduciary for Holders of Senior
                               Indebtedness.

                The Trustee, in its capacity as trustee under this Indenture,
         shall not be deemed to owe any fiduciary duty to the holders of Senior
         Indebtedness and shall not be liable to any such holders if it shall in
         good faith mistakenly pay over or distribute to Holders of Securities
         or to the Company or to any other Person cash, property or securities
         to which any holders of Senior Indebtedness shall be entitled by virtue
         of this Article or otherwise.

                SECTION 13.11. Rights of Trustee as Holder of Senior
                               Indebtedness; Preservation of Trustee's
                               Rights.

                The Trustee in its individual capacity shall be entitled to all
         the rights set forth in this Article with respect to any Senior
         Indebtedness that may at any time be held by it, to the same extent as
         any other holder of Senior Indebtedness, and nothing in this Indenture
         shall deprive the Trustee of any of its rights as such holder.

                SECTION 13.12. Article Applicable to Paying Agents.

                In case at any time any Paying Agent other than the Trustee
         shall have been appointed by the Company and be then acting hereunder,
         the term "Trustee" as used in this Article shall in such case (unless
         the context otherwise requires) be construed as extending to and
         including such Paying Agent within its meaning as fully for all intents
         and purposes as if such Paying Agent were named in this Article in
         addition to or in place of the Trustee.

                SECTION 13.13. Certain Conversions or Exchanges Deemed
                               Payment.

                For purposes of this Article only, (a) the issuance and delivery
         of junior securities upon conversion or exchange of Securities of any
         series shall not be deemed to constitute a
<PAGE>   99

                                       - 93 -


         payment or distribution on account of the principal of (or premium, if
         any, on) or interest (including any Additional Interest) on such
         Securities or on account of the purchase or other acquisition of such
         Securities, and (b) the payment, issuance or delivery of cash, property
         or securities (other than junior securities) upon conversion or
         exchange of a Security of any series shall be deemed to constitute
         payment on account of the principal of such security. For the purposes
         of this Section, the term "junior securities" means (i) shares of any
         stock of any class of the Company, and (ii) securities of the Company
         that are subordinated in right of payment to all Senior Indebtedness
         that may be outstanding at the time of issuance or delivery of such
         securities to substantially the same extent as, or to a greater extent
         than, the Securities are so subordinated as provided in this Article.

         Act, it is being effected in accordance with Rule 144A, Rule 904 of
         Regulation S or Rule 144 under the Securities Act and all applicable
         securities laws of the states of the United States and other
         jurisdictions. Accordingly, the Owner hereby further certifies that

                a person that the Owner and any person acting on its behalf
                reasonably believe is a "qualified institutional buyer" within
                the meaning of Rule 144A, acquiring for its own account or for
                the account of a qualified institutional buyer; and

                          (B) the Owner and any person acting on its behalf have
                taken reasonable steps to ensure that the Transferee is aware
                that the Owner may be relying on Rule 144A in connection with
                the transfer; and

                acting in behalf of any of the foregoing;

                          (B)  the offer of the Specified Securities was

                     Transferee was outside the United States or the Owner and
                     any person acting on its behalf reasonably believed that
                     the Transferee was outside the United States, or

                               (ii) the transaction is being executed in, on or
