<PAGE>   24

         1.3  FORM 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 an Opinion of Counsel, provided
that such officer, after reasonable inquiry, has no reason to believe and does
not believe that the Opinion of Counsel with respect to the matters upon which
his certificate or opinion is based is erroneous. Any such 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, provided that such counsel, after reasonable inquiry, has no
reason to believe and does not believe 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 or any Security, they may, but need not, be
consolidated and form one instrument.

         1.4  ACTS OF HOLDERS.

         (1) Any request, demand, authorization, direction, notice, consent,
waiver or other action provided by or pursuant to this Indenture to be given 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. If, but only if, Securities of a series are issuable as
Bearer Securities, any request, demand, authorization, direction, notice,
consent, waiver or other action provided in or pursuant to this Indenture to be
given or taken by Holders of Securities of such series may, alternatively, be
embodied in and evidenced by the record of Holders of Securities of such series
voting in favor thereof, either in person or by proxies duly appointed in
writing, at any meeting of Holders of Securities of such series duly called and
held in accordance with the provisions of Article 15, or a combination of such
instruments and any such record. Except as herein

                                       18
<PAGE>   25

otherwise expressly provided, such action shall become effective when such
instrument or instruments or record or both are delivered to the Trustee and,
where it is hereby expressly required, to the Company. Such instrument or
instruments and any such record (and the action embodied therein and evidenced
thereby) are herein sometimes referred to as the "Act" of the Holders signing
such instrument or instruments or so voting at any such meeting. Proof of
execution of any such instrument or of a writing appointing any such agent, or
of the holding by any Person of a Security, shall be sufficient for any purpose
of this Indenture and (subject to Section 315 of the Trust Indenture Act)
conclusive in favor of the Trustee and the Company and any agent of the Trustee
and the Company, if made in the manner provided in this section. The record of
any meeting of Holders of Securities shall be proved in the manner provided in
Section 15.6.

                  Without limiting the generality of this Section 1.4, unless
         otherwise provided in or pursuant to this Indenture, a Holder,
         including a U.S. Depository that is a Holder of a global Security, may
         make, give or take, by a proxy or proxies, duly appointed in writing,
         any request, demand, authorization, direction, notice, consent, waiver
         or other Act provided in or pursuant to this Indenture to be made,
         given or taken by Holders, and a U.S. Depository that is a Holder of a
         global Security may provide its proxy or proxies to the beneficial
         owners of interests in any such global Security through such U.S.
         Depository's standing instructions and customary practices.

                  The Company shall fix a record date for the purpose of
         determining the Persons who are beneficial owners of interest in any
         permanent global Security held by a U.S. Depository entitled under the
         procedures of such U.S. Depository to make, give or take, by a proxy or
         proxies duly appointed in writing, any request, demand, authorization,
         direction, notice, consent, waiver or other Act provided in or pursuant
         to this Indenture to be made, given or taken by Holders. If such a
         record date is fixed, the Holders on such record date or their duly
         appointed proxy or proxies, and only such Persons, shall be entitled to
         make, give or take such request, demand, authorization, direction,
         notice, consent, waiver or other Act, whether or not such Holders
         remain Holders after such record date. No such request, demand,
         authorization, direction, notice, consent, waiver or other Act shall be
         valid or effective if made, given or taken more than 90 days after such
         record date.

         (2) The fact and date of the execution by any Person of any such
instrument or writing referred to in this Section 1.4 may be proved in any
reasonable manner; and the Trustee may in any instance require further proof
with respect to any of the matters referred to in this section.

         (3) The ownership, principal amount and serial numbers of Registered
Securities held by any Person, and the date of the commencement and the date of
the termination of holding the same, shall be proved by the Security Register.

         (4) The ownership, principal amount and serial numbers of Bearer
Securities held by any Person, and the date of the commencement and the date of
the termination of holding the same, may

                                       19
<PAGE>   26

be proved by the production of such Bearer Securities or by a certificate
executed, as depositary, by any trust company, bank, banker or other depositary
reasonably acceptable to the Company, wherever situated, if such certificate
shall be deemed by the Company and the Trustee to be satisfactory, showing that
at the date therein mentioned such Person had on deposit with such depositary,
or exhibited to it, the Bearer Securities therein described; or such facts may
be proved by the certificate or affidavit of the Person holding such Bearer
Securities, if such certificate or affidavit is deemed by the Trustee to be
satisfactory. The Trustee and the Company may assume that such ownership of any
Bearer Security continues until (i) another certificate or affidavit bearing a
later date issued in respect of the same Bearer Security is produced, or (ii)
such Bearer Security is produced to the Trustee by some other Person, or (iii)
such Bearer Security is surrendered in exchange for a Registered Security, or
(iv) such Bearer Security is no longer Outstanding. The ownership, principal
amount and serial numbers of Bearer Securities held by the Person so executing
such instrument or writing and the date of the commencement and the date of the
termination of holding the same may also be proved in any other manner which the
Company and the Trustee deem sufficient.

         (5) If the Company shall solicit from the Holders of any Registered
Securities any request, demand, authorization, direction, notice, consent,
waiver or other Act, the Company may at its option (but is not obligated to), by
Board Resolution, fix in advance a record date for the determination of Holders
of Registered Securities entitled to give such request, demand, authorization,
direction, notice, consent, waiver or other Act. If such a record date is fixed,
such request, demand, authorization, direction, notice, consent, waiver or other
Act may be given before or after such record date, but only the Holders of
Registered Securities of record at the close of business on such record date
shall be deemed to be Holders for the purpose of determining whether Holders of
the requisite proportion of Outstanding Securities have authorized or agreed or
consented to such request, demand, authorization, direction, notice, consent,
waiver or other Act, and for that purpose the Outstanding Securities shall be
computed as of such record date; provided that no such authorization, agreement
or consent by the Holders of Registered Securities shall be deemed effective
unless it shall become effective pursuant to the provisions of this Indenture
not later than six months after the record date.

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

         1.5  NOTICES, ETC. TO THE TRUSTEE AND THE COMPANY.

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

         (1) the Trustee by any Holder or the Company shall be sufficient,
subject to the requirements of this Indenture, 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 or any Holder shall be sufficient for
every purpose hereunder (unless otherwise herein expressly provided) if in
writing and mailed, first-class postage prepaid, to the Company addressed to the
attention of its Chief Financial Officer, Controller or Secretary, 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.

         1.6  NOTICE TO HOLDERS OF SECURITIES; WAIVER.

         Except as otherwise expressly provided in or pursuant to this
Indenture, where this Indenture provides for notice to Holders of Securities of
any event,

         (1) such notice shall be sufficiently given to Holders of Registered
Securities if in writing and mailed, first-class postage prepaid, to each Holder
of a Registered Security affected by such event, at his address as it appears in
the Security Register, not later than the latest date, and not earlier than the
earliest date, prescribed for the giving of such notice; and

         (2) such notice shall be sufficiently given to Holders of Bearer
Securities, if any, if published in an Authorized Newspaper in the city of New
York and, if such Securities are then listed on any stock exchange outside the
United States, in an Authorized Newspaper in such city as the Company shall
advise the Trustee that such stock exchange so requires, on a Business Day at
least twice, the first such publication to be not earlier than the earliest date
and the second such publication not later than the latest date prescribed for
the giving of such notice.

         In any case where notice to Holders of Registered Securities is given
by mail, neither the failure to mail such notice, nor any defect in any notice
so mailed, to any particular Holder of a Registered Security shall affect the
sufficiency of such notice with respect to other Holders of Registered
Securities or the sufficiency of any notice to Holders of Bearer Securities
given as provided herein. Any notice which is mailed in the manner herein
provided shall be conclusively presumed to have been duly given or provided. In
the case by reason of the suspension of regular mail service or by reason of any
other cause it shall be impracticable to give such notice by mail, then such
notification as shall be made with the approval of the Trustee shall constitute
a sufficient notification for every purpose hereunder.

                                       21

<PAGE>   28

         In case by reason of the suspension of publication of any Authorized
Newspaper or Authorized Newspapers or by reason of any other cause it shall be
impracticable to publish any notice to Holders of Bearer Securities as provided
above, then such notification to Holders of Bearer Securities as shall be given
with the approval of the Trustee shall constitute sufficient notice to such
Holders for every purpose hereunder. Neither failure to give notice by
publication to Holders of Bearer Securities as provided above, nor any defect in
any notice so published, shall affect the sufficiency of any notice mailed to
Holders of Registered Securities as provided above.

         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 of Securities 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.

         1.7  LANGUAGE OF NOTICES.

Securities, in any case where any Interest Payment Date, Stated Maturity or
Maturity of any Security, or the last date on which a Holder has the right to

         1.16  JUDGMENT CURRENCY.

         The Company agrees, to the fullest extent that it may effectively do so
under applicable law, that (a) if for the purpose of obtaining judgment in any
court it is necessary to convert the sum due in respect of the principal of, or
premium or interest, if any, or Additional Amounts on the Securities of any
series (the "Required Currency") into a currency in which a judgment will be
rendered (the "Judgment Currency"), the rate of exchange used shall be the rate
at which in accordance with normal banking procedures the Trustee could purchase
in the city of New York the requisite amount

                                       23
<PAGE>   30

of the Required Currency with the Judgment Currency on the New York Banking Day
preceding the day on which a final unappealable judgment is given and (b) its
obligations under this Indenture to make payments in the Required Currency (i)
shall not be discharged or satisfied by any tender, or any recovery pursuant to
any judgment (whether or not entered in accordance with clause (a)), in any
currency other than the Required Currency, except to the extent that such tender
or recovery shall result in the actual receipt, by the payee, of the full amount
of the Required Currency expressed to be payable in respect of such payments,
(ii) shall be enforceable as an alternative or additional cause of action for
the purpose of recovering in the Required Currency the amount, if any, by which
such actual receipt shall fall short of the full amount of the Required Currency
so expressed to be payable and (iii) shall not be affected by judgment being
obtained for any other sum due under this Indenture. For purposes of the

of law, or by the enforcement of any assessment or penalty or otherwise; it

Securities, the Securities shall not be issuable in temporary or permanent
global form. If Securities of a series shall be issuable in global form, any
such Security may provide that it or any number of such Securities shall
represent the aggregate amount of all Outstanding Securities of such series (or
such lesser amount as is permitted by the terms thereof) from time to time
endorsed thereon and may also provide that the aggregate amount of Outstanding
Securities represented thereby may from time to time be increased or reduced to
reflect exchanges. Any endorsement of any Security in global form to reflect the

Holders, of Outstanding Securities represented thereby shall be made in such
manner and by such Person or Persons as shall be specified therein or in the
Company Order to be delivered pursuant to Section 3.3 or 3.4 with respect

respect to a Security in global form shall be in writing but need not be
accompanied by or contained in an Officer's Certificate and need not be
accompanied by an Opinion of Counsel.

         Notwithstanding the provisions of Section 3.7, unless otherwise
specified in or pursuant to this Indenture or any Security, payment of principal
of, any premium and interest on, and any Additional Amounts in respect of, any
Security in temporary or permanent global form shall be made to the Person or
Persons specified therein.

         Notwithstanding the provisions of Section 3.8 and except as provided in
the preceding paragraph, the Company, the Trustee and any agent of the Company
or the Trustee shall treat as the Holder of such principal amount of Outstanding
Securities represented by a global Security (i) in the case of a global Security
in registered form, the Holder of such global Security in registered form, or
(ii) in the case of a global Security in bearer form, the Person or Persons
specified pursuant to Section 3.1.

         3.3  EXECUTION, AUTHENTICATION, DELIVERY AND DATING.

         Securities shall be executed on behalf of the Company by its Chairman
of the Board, its President, its Chief Financial Officer, its Controller or a
Vice President under its corporate seal, if any, reproduced thereon and attested
by its Secretary or one of its Assistant Secretaries. Coupons shall be executed

the Company shall bind the Company, notwithstanding that such individuals or any
of them have ceased to hold such offices prior to the authentication and
delivery of such Securities and Coupons or did not hold such offices at the date
of original issuance of such Securities or Coupons.

         At any time and from time to time after the execution and delivery of
this Indenture, the Company may deliver Securities, together with any Coupons
appertaining thereto, executed by the Company, to the Trustee for authentication
and, provided that the Board Resolution and Officer's Certificate or
supplemental indenture or indentures with respect to such Securities referred to
in Section 3.1 and a Company Order for the authentication and delivery of such
Securities have been delivered to the Trustee, the Trustee in accordance with
the Company Order and subject to the provisions hereof and of such Securities
shall authenticate and deliver such Securities. In authenticating such
Securities, and accepting the additional responsibilities under this Indenture
in relation to such Securities and any Coupons appertaining thereto, the Trustee
shall be entitled to receive, and (subject to Sections 315(a) through 315(d) of
the Trust Indenture Act) shall be fully protected in relying upon,

         (1)      an Opinion of Counsel to the effect that:

                  (a) the form or forms and terms of such Securities and
         Coupons, if any, have been established in conformity with the
         provisions of this Indenture;

                  (b) all conditions precedent to the authentication and
         delivery of such Securities and Coupons, if any, appertaining thereto,
         have been complied with and that such Securities and Coupons, when
         completed by appropriate insertions, executed under the Company's
         corporate seal, if any, and attested by duly authorized officers of the
         Company, delivered by duly authorized officers of the Company to the
         Trustee for authentication pursuant to this Indenture, and
         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 legally valid and binding obligations of the
         Company, enforceable against the Company in accordance with their
         terms, except as enforcement thereof may be subject to or limited by
         bankruptcy, insolvency, reorganization, moratorium, arrangement,
         fraudulent conveyance, fraudulent transfer or other similar laws
         relating to or affecting creditors' rights generally, and subject to
         general principles of equity (regardless of whether enforcement is
         sought in

                                       31

         a proceeding in equity or at law) and will entitle the Holders thereof
         to the benefits of this Indenture; such Opinion of Counsel need express
         no opinion as to the availability of equitable remedies and may assume
         that the laws of the State of New York are identical in all relevant
         aspects to the substantive laws of the State of Ohio;

                  (c) all laws and requirements in respect of the execution and
         delivery by the Company of such Securities and Coupons, if any, have
         been complied with in all material respects; and

                  (d) this Indenture has been qualified under the Trust
         Indenture Act; and

         (2) an Officer's Certificate stating that, to the best knowledge of the
Persons executing such certificate, all conditions precedent to the execution,
authentication and delivery of such Securities and Coupons, if any, appertaining
thereto, have been complied with, and no event which is, or after notice or
lapse of time would become, an Event of Default with respect to any of the
Securities shall have occurred and be continuing.

         If all the Securities of any series are not to be issued at one time,
it shall not be necessary to deliver an Opinion of Counsel and an Officer's
Certificate at the time of issuance of each Security, but such opinion and
certificate, with appropriate modifications, shall be delivered at or before the
time of issuance of the first Security of such series. After any such first
delivery, any separate written request by an Authorized Officer of the Company
or any person designated in writing by an Authorized Officer that the Trustee
authenticate and deliver Securities of such series for original issue will be
deemed to be a certification by the Company that all conditions precedent
provided for in this Indenture relating to authentication and delivery of such
Securities continue to have been complied with and that no Event of Default with
respect to any of the Securities has occurred or is continuing and the Trustee
shall be fully protected in relying upon that certification.

         The Trustee shall not be required to authenticate or to cause an
Authenticating Agent to authenticate any 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 which is not reasonably acceptable to the Trustee or if the Trustee,
being advised by counsel, determines that such action may not lawfully be taken.

         Each Registered Security shall be dated the date of its authentication.
Each Bearer Security and any Bearer Security in global form shall be dated as of
the date specified in or pursuant to this Indenture.

         No Security or Coupon appertaining thereto 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 in Section 2.2 or 6.12 executed by or on behalf of the
Trustee or by the Authenticating Agent by the manual signature of one of its

                                       32
<PAGE>   39

authorized officers. Such certificate upon any Security shall be conclusive
evidence, and the only evidence, that such Security has been duly authenticated
and delivered hereunder. Except as permitted by Section 3.6 or 3.7, the Trustee
shall not authenticate and deliver any Bearer Security unless all Coupons
appertaining thereto then matured have been detached and cancelled.

         3.4  TEMPORARY SECURITIES.

         Pending the preparation of definitive Securities, the Company may
execute and deliver to the Trustee and, upon Company Order, the Trustee shall
authenticate and deliver, in the manner provided in Section 3.3, temporary
Securities in lieu thereof which are printed, lithographed, typewritten,
mimeographed or otherwise produced, in any authorized denomination,
substantially of the tenor of the definitive Securities in lieu of which they
are issued, in registered form or, if authorized in or pursuant to this
Indenture, in bearer form with one or more Coupons or without Coupons and with
such appropriate insertions, omissions, substitutions and other variations as
the officers of the Company executing such Securities may determine, as
conclusively evidenced by their execution of such Securities. Such temporary
Securities may be in global form.

         Except in the case of temporary Securities in global form, which shall
be exchanged in accordance with the provisions thereof, if temporary Securities
are issued, the Company shall cause definitive Securities to be prepared without
unreasonable delay. After the preparation of definitive Securities of the same
series and containing terms and provisions that are identical to those of any
temporary Securities, such temporary Securities shall be exchangeable for such
definitive Securities upon surrender of such temporary Securities at an Office
or Agency for such Securities, without charge to any Holder thereof. Upon
surrender for cancellation of any one or more temporary Securities (accompanied
by any unmatured Coupons appertaining thereto), the Company shall execute and
the Trustee shall authenticate and deliver in exchange therefor a like principal
amount of definitive Securities of authorized denominations of the same series
and containing identical terms and provisions; provided, however, that no
definitive Bearer Security, except as provided in or pursuant to this Indenture,
shall be delivered in exchange for a temporary Registered Security; and
provided, further, that a definitive Bearer Security shall be delivered in
exchange for a temporary Bearer Security only in compliance with the conditions
set forth in or pursuant to this Indenture. Unless otherwise provided in or
pursuant to this Indenture with respect to a temporary global Security, 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.

         3.5  REGISTRATION, TRANSFER AND EXCHANGE.

         With respect to the Registered Securities of each series, if any, the
Company shall cause to be kept a register (each such register being herein
sometimes referred to as the "Security Register") at an Office or Agency for
such series in which, subject to such reasonable regulations as it may
prescribe, the Company shall provide for the registration of the Registered
Securities of such series and of transfers of the Registered Securities of such
series. Such Office or Agency shall be the

                                       33
<PAGE>   40

"Security Registrar" for that series of Securities. Unless otherwise specified
in or pursuant to this Indenture or the Securities, the Trustee shall be the
initial Security Registrar for each series of Securities. The Company shall have
the right to remove and replace from time to time the Security Registrar for any
series of Securities; provided that no such removal or replacement shall be
effective until a successor Security Registrar with respect to such series of
Securities shall have been appointed by the Company and shall have accepted such
appointment by the Company. In the event that the Trustee shall not be or shall
cease to be Security Registrar with respect to a series of Securities, it shall
have the right to examine the Security Register for such series at all
reasonable times. There shall be only one Security Register for each series of
Securities.

         Upon surrender for registration of transfer of any Registered Security
of any series at any Office or Agency for such series, the Company shall
execute, and the Trustee shall authenticate and deliver, in the name of the
designated transferee or transferees, one or more new Registered Securities of
the same series denominated as authorized in or pursuant to this Indenture, of a
like aggregate principal amount bearing a number not contemporaneously
outstanding and containing identical terms and provisions.

         At the option of the Holder, Registered Securities of any series may be
exchanged for other Registered Securities of the same series containing
identical terms and provisions, in any authorized denominations, and of a like
aggregate principal amount, upon surrender of the Securities to be exchanged at
any Office or Agency for such series. Whenever any Registered Securities are so
surrendered for exchange, the Company shall execute, and the Trustee shall
authenticate and deliver, the Registered Securities which the Holder making the
exchange is entitled to receive.

         If provided in or pursuant to this Indenture, with respect to
Securities of any series, at the option of the Holder, Bearer Securities of such
series may be exchanged for Registered Securities of such series containing
identical terms, denominated as authorized in or pursuant to this Indenture and
in the same aggregate principal amount, upon surrender of the Bearer Securities
to be exchanged at any Office or Agency for such series, with all unmatured
Coupons and all matured Coupons in default thereto appertaining. If the Holder
of a Bearer Security is unable to produce any such unmatured Coupon or Coupons
or matured Coupon or Coupons in default, such exchange may be effected if the
Bearer Securities are accompanied by payment in funds acceptable to the Company
and the Trustee in an amount equal to the face amount of such missing Coupon or
Coupons, or the surrender of such missing Coupon or Coupons may be waived by the
Company and the Trustee if there is furnished to them such security or indemnity
as they may require to save each of them and any Paying Agent harmless. If
thereafter the Holder of such Bearer Security shall surrender to any Paying
Agent any such missing Coupon in respect of which such a payment shall have been
made, such Holder shall be entitled to receive the amount of such payment;
provided, however, that, except as otherwise provided in Section 10.2, interest
represented by Coupons shall be payable only upon presentation and surrender of
those Coupons at an Office or Agency for such series located outside the United
States. Notwithstanding the foregoing, in case a Bearer Security of any series
is surrendered at any such Office or Agency for such series in exchange for a
Registered Security of

                                       34
<PAGE>   41

such series and like tenor after the close of business at such Office or Agency
on (i) any Regular Record Date and before the opening of business at such Office
or Agency on the next succeeding Interest Payment Date, or (ii) any Special
Record Date and before the opening of business at such Office or Agency on the
related date for payment of Defaulted Interest, such Bearer Security shall be
surrendered without the Coupon relating to such Interest Payment Date or
proposed date of payment, as the case may be (or, if such Coupon is so
surrendered with such Bearer Security, such Coupon shall be returned to the
Person so surrendering the Bearer Security), and interest or Defaulted Interest,
as the case may be, shall not be payable on such Interest Payment Date or
proposed date for payment, as the case may be, in respect of the Registered
Security issued in exchange for such Bearer Security, but shall be payable only
to the Holder of such Coupon when due in accordance with the provisions of this
Indenture.

         If provided in or pursuant to this Indenture with respect to Securities
of any series, at the option of the Holder, Registered Securities of such series
may be exchanged for Bearer Securities upon such terms and conditions as may be
provided in or pursuant to this Indenture with respect to such series.

         Whenever any Securities are surrendered for exchange as contemplated by
the immediately preceding two paragraphs, the Company shall execute, and the
Trustee shall authenticate and deliver, the Securities which the Holder making
the exchange is entitled to receive.

         Notwithstanding the foregoing, except as otherwise provided in or
pursuant to this Indenture, any global Security shall be exchangeable for
definitive Securities only if (i) the Depository is at any time unwilling,
unable or ineligible to continue as depository and a successor depository is not
appointed by the Company within 90 days of the date the Company is so informed
in writing, (ii) the Company executes and delivers to the Trustee a Company
Order to the effect that such global Security shall be so exchangeable, or (iii)
an Event of Default has occurred and is continuing with respect to the
Securities. If the beneficial owners of interests in a global Security are
entitled to exchange such interests for definitive Securities as the result of
an event described in clause (i), (ii) or (iii) of the preceding sentence, then
without unnecessary delay but in any event not later than the earliest date on
which such interests may be so exchanged, the Company shall deliver to the
Trustee definitive Securities in such form and denominations as are required by
or pursuant to this Indenture, and of the same series, containing identical
terms and in aggregate principal amount equal to the principal amount of such
global Security, executed by the Company. On or after the earliest date on which
such interests may be so exchanged, such global Security shall be surrendered
from time to time by the U.S. Depository or such other Depository as shall be
specified in the Company Order with respect thereto, and in accordance with
instructions given to the Trustee and the U.S. Depository or such other
Depository, as the case may be (which instructions shall be in writing but need
not be contained in or accompanied by an Officer's Certificate or be accompanied
by an Opinion of Counsel), as shall be specified in the Company Order with
respect thereto to the Trustee, as the Company's agent for such purpose, to be
exchanged, in whole or in part, for definitive Securities as described above
without charge. The Trustee shall authenticate and make available for

                                       35
<PAGE>   42

delivery, in exchange for each portion of such surrendered global Security, a
like aggregate principal amount of definitive Securities of the same series of
authorized denominations and of like tenor as the portion of such global
Security to be exchanged, which (unless such Securities are not issuable both as
Bearer Securities and as Registered Securities, in which case the definitive
Securities exchanged for the global Security shall be issuable only in the form
in which the Securities are issuable, as provided in or pursuant to this
Indenture) shall be in the form of Bearer Securities or Registered Securities,
or any combination thereof, as shall be specified by the beneficial owner
thereof, but subject to the satisfaction of any certification or other
requirements to the issuance of Bearer Securities; provided, however, that no
such exchanges may occur during a period beginning at the opening of business 15
days before any selection of Securities of the same series to be redeemed and
ending on the relevant Redemption Date; and provided, further, that (unless
otherwise provided in or pursuant to this Indenture) no Bearer Security
delivered in exchange for a portion of a global Security shall be mailed or
otherwise delivered to any location in the United States. Promptly following any
such exchange in part, such global Security shall be returned by the Trustee to
such Depository or the U.S. Depository, as the case may be, or such other
Depository or U.S. Depository referred to above in accordance with the
instructions of the Company referred to above. If a Registered Security is
issued in exchange for any portion of a global Security after the close of
business at the Office or Agency for such Security where such exchange occurs on
or after (i) any Regular Record Date for such Security and before the opening of
business at such Office or Agency on the next succeeding Interest Payment Date,
or (ii) any Special Record Date for such Security and before the opening of
business at such Office or Agency on the related proposed date for payment of
interest or Defaulted Interest, as the case may be, interest shall not be
payable on such Interest Payment Date or proposed date for payment, as the case
may be, in respect of such Registered Security, but shall be payable on such
Interest Payment Date or proposed date for payment, as the case may be, only to
the Person to whom interest in respect of such portion of such global Security
shall be payable in accordance with the provisions of this Indenture.

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

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

         No service charge shall be made for any registration of transfer or
exchange, or redemption of Securities, but the Company may require payment of a
sum sufficient to cover any tax or other governmental charge and any other
expenses (including fees and expenses of the Trustee) that may

                                       36
<PAGE>   43

be imposed in connection with any registration of transfer or exchange of
Securities, other than exchanges pursuant to Section 3.4, 9.5 or 11.7 not
involving any transfer.

         Except as otherwise provided in or pursuant to this Indenture, the
Company shall not be required (i) to issue, register the transfer of or exchange
any Securities during a period beginning at the opening of business 15 days
before the day of mailing of a notice of redemption of Securities of like tenor
and the same series under Section 11.3 and ending at the close of business on
the day of such mailing, or (ii) to register the transfer of or exchange any
Registered Security selected for redemption in whole or in part, except in the
case of any Security to be redeemed in part, the portion thereof not to be
redeemed, or (iii) to exchange any Bearer Security selected for redemption
except, to the extent provided with respect to such Bearer Security, that such
Bearer Security may be exchanged for a Registered Security of like tenor and the
same series, provided that such Registered Security shall be immediately
surrendered for redemption with written instruction for payment consistent with
the provisions of this Indenture or (iv) to issue, register the transfer of or
exchange any Security which, in accordance with its terms, has been surrendered
for repayment at the option of the Holder, except the portion, if any, of such
Security not to be so repaid.

         3.6  MUTILATED, DESTROYED, LOST AND STOLEN SECURITIES.

         If any mutilated Security or a Security with a mutilated Coupon
appertaining to it is surrendered to the Trustee, subject to the provisions of
this Section 3.6, the Company shall execute and the Trustee shall authenticate
and deliver in exchange therefor a new Security of the same series containing
identical terms and of like principal amount and bearing a number not
contemporaneously outstanding, with Coupons appertaining thereto corresponding
to the Coupons, if any, appertaining to the surrendered Security.

         If there be delivered to the Company and the Trustee (i) evidence to
their satisfaction of the destruction, loss or theft of any Security or Coupon,
and (ii) such security or indemnity as may be required by them to save each of
them and any agent of either of them harmless, then, in the absence of notice to
the Company or the Trustee that such Security or Coupon has been acquired by a
bona fide purchaser, the Company shall execute and, upon the Company's request
the Trustee shall authenticate and deliver, in exchange for or in lieu of any
such mutilated, destroyed, lost or stolen Security or in exchange for the
Security to which a destroyed, lost or stolen Coupon appertains with all
appurtenant Coupons not destroyed, lost or stolen, a new Security of the same
series containing identical terms and of like principal amount and bearing a
number not contemporaneously outstanding, with Coupons appertaining thereto
corresponding to the Coupons, if any, appertaining to such destroyed, lost or
stolen Security or to the Security to which such destroyed, lost or stolen
Coupon appertains.

         Notwithstanding the foregoing provisions of this Section 3.6, in case
any mutilated, destroyed, lost or stolen Security or Coupon 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 or Coupon;

                                       37
<PAGE>   44

provided, however, that payment of principal of, any premium or interest on or
any Additional Amounts with respect to any Bearer Securities shall, except as
otherwise provided in Section 10.2, be payable only at an Office or Agency for
such Securities located outside the United States and, unless otherwise provided
in or pursuant to this Indenture, any interest on Bearer Securities and any
Additional Amounts with respect to such interest shall be payable only upon
presentation and surrender of the Coupons appertaining thereto.

         Upon the issuance of any new Security under this Section 3.6, 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, with any Coupons appertaining thereto issued
pursuant to this Section 3.6 in lieu of any destroyed, lost or stolen Security,
or in exchange for a Security to which a destroyed, lost or stolen Coupon
appertains shall constitute a separate obligation of the Company, whether or not
the destroyed, lost or stolen Security and Coupons appertaining thereto or the
destroyed, lost or stolen Coupon 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 and any
Coupons, if any, duly issued hereunder.

         The provisions of this Section 3.6, as amended or supplemented pursuant
to this Indenture with respect to particular Securities or generally, shall be
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 or Coupons.

         3.7 PAYMENT OF INTEREST AND CERTAIN ADDITIONAL AMOUNTS; RIGHTS TO
INTEREST AND CERTAIN ADDITIONAL AMOUNTS PRESERVED.

         Unless otherwise provided in or pursuant to this Indenture, any
interest on and any Additional Amounts with respect to any Registered Security
which shall be payable, and are punctually paid or duly provided for, on any
Interest Payment Date shall be paid to the Person in whose name such Security
(or one or more Predecessor Securities) is registered as of the close of
business on the Regular Record Date for such interest.

         Unless otherwise provided in or pursuant to this Indenture, any
interest on and any Additional Amounts with respect to any Registered Security
which shall be payable, but shall not be punctually paid or duly provided for,
on any Interest Payment Date for such Registered Security (herein called
"Defaulted Interest") shall forthwith cease to be payable to the Holder thereof
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, as provided
in Clause (1) or (2) below:

                                       38
<PAGE>   45

         (1) The Company may elect to make payment of any Defaulted Interest to
the Person in whose name such Registered Security (or a Predecessor Security
thereof) shall be registered at the close of business on a Special Record Date
for the payment of such Defaulted Interest, which shall be fixed by the Company
in the following manner. The Company shall notify the Trustee in writing of the
amount of Defaulted Interest proposed to be paid on such Registered Security,
the Special Record Date therefor 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
on or prior to the date of the proposed payment, such money when so deposited to
be held in trust for the benefit of the Person entitled to such Defaulted
Interest as provided in this clause (1). The Special Record Date for the payment
of such Defaulted Interest 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
notification to the Trustee of the proposed payment. The Trustee shall, in the
name and at the expense of the Company, cause notice of the proposed payment of
such Defaulted Interest and the Special Record Date therefor to be mailed,
first-class postage prepaid, to the Holder of such Registered Security (or a
Predecessor Security thereof) at his address as it appears in the Security
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 an Authorized Newspaper 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 Person in whose name such Registered
Security (or a Predecessor Security thereof) shall be registered at the close of
business on such Special Record Date and shall no longer be payable pursuant to
the following clause (2).

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

         Unless otherwise provided in or pursuant to this Indenture or the
Securities of any particular series pursuant to the provisions of this
Indenture, at the option of the Company, interest on Registered Securities that
bear interest may be paid by mailing a check to the address of the Person
entitled thereto as such address shall appear in the Security Register or by
transfer to an account maintained by the payee with a bank located in the United
States.

         Subject to the foregoing provisions of this Section and Section 3.5,
each Security delivered under this Indenture upon registration of transfer of or
in exchange for or in lieu of any other Security shall carry the rights to
interest accrued and unpaid, and to accrue, which were carried by such other
Security.

                                       39
<PAGE>   46

         In the case of any Registered Security of any series that is
convertible into other securities of the Company or exchangeable for securities
of another issuer, which Registered Security is converted or exchanged after any
Regular Record Date and on or prior to the next succeeding Interest Payment Date
(other than any Registered Security with respect to which the Stated Maturity is
prior to such Interest Payment Date), interest with respect to which the Stated
Maturity is on such Interest Payment Date shall be payable on such Interest
Payment Date notwithstanding such conversion or exchange, and such interest
(whether or not punctually paid or duly provided for) shall be paid to the
Person in whose name that Registered Security (or one or more predecessor
Registered Securities) is registered at the close of business on such Regular
Record Date. Except as otherwise expressly provided in the immediately preceding
sentence, in the case of any Registered Security which is converted or
exchanged, interest with respect to which the Stated Maturity is after the date
of conversion or exchange of such Registered Security shall not be payable.

         3.8  PERSONS DEEMED OWNERS.

         Prior to due presentment of a Registered Security for registration of
transfer, the Company, the Trustee and any agent of the Company or the Trustee
may treat the Person in whose name such Registered Security is registered in the
Security Register as the owner of such Registered Security for the purpose of
receiving payment of principal of, any premium and (subject to Sections 3.5 and
3.7) interest on and any Additional Amounts with respect to such Registered
Security and for all other purposes whatsoever, whether or not any payment with
respect to such Registered Security shall be overdue, and none of the Company,
the Trustee or any agent of the Company or the Trustee shall be affected by
notice to the contrary.

         The Company, the Trustee and any agent of the Company or the Trustee
may treat the bearer of any Bearer Security or the bearer of any Coupon as the
absolute owner of such Security or Coupon for the purpose of receiving payment
thereof or on account thereof and for all other purposes whatsoever, whether or
not any payment with respect to such Security or Coupon shall be overdue, and
none of the Company, the Trustee or 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 Depository shall have any rights under this Indenture with respect
to such global Security, and such Depository 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. None of the Company, the Trustee, any
Paying Agent or the Security Registrar will have any responsibility or liability
for any aspect of the records relating to or payments made on account of
beneficial ownership interests of a global Security or for maintaining,
supervising or reviewing any records relating to such beneficial ownership
interests.

         3.9  CANCELLATION.

         All Securities and Coupons surrendered for payment, redemption,
registration of transfer, exchange or conversion or for credit against any
sinking fund payment shall, if surrendered to any Person other than the Trustee,
be delivered to the Trustee, and any such Securities and Coupons, as well as
Securities and Coupons surrendered directly to the Trustee for any such purpose,
shall be cancelled promptly by the Trustee. The Company may at any time deliver
to the Trustee for cancellation any Securities previously authenticated and
delivered hereunder which the Company may have acquired in any manner
whatsoever, and all Securities so delivered shall be cancelled promptly by the
Trustee. No Securities shall be authenticated in lieu of or in exchange for any
Securities cancelled as provided in this section, except as expressly permitted
by or pursuant to this Indenture. All cancelled Securities and Coupons held by
the Trustee shall be destroyed by the Trustee, unless by a Company Order the
Company directs their return to it.

         3.10  COMPUTATION OF INTEREST.

         Except as otherwise provided in or pursuant to this Indenture or in any
Security, interest on the Securities shall be computed on the basis of a 360-day
year of twelve 30-day months.

                                    ARTICLE 4

                     SATISFACTION AND DISCHARGE OF INDENTURE
                     ---------------------------------------

         4.1  SATISFACTION AND DISCHARGE.

         Upon the direction of the Company by a Company Order, this Indenture
shall cease to be of further effect with respect to any series of Securities
specified in such Company Order and any Coupons appertaining thereto, and the
Trustee, on receipt of a Company Order, at the expense of the Company, shall
execute proper instruments acknowledging satisfaction and discharge of this
Indenture as to such series, when

         (1)      either:

                  (a) all Securities of such series theretofore authenticated
         and delivered and all Coupons appertaining thereto (other than (i)
         Coupons appertaining to Bearer Securities of such series surrendered in
         exchange for Registered Securities of such series and maturing after
         such exchange whose surrender is not required or has been waived as
         provided in Section 3.5, (ii) Securities and Coupons of such series
         which have been destroyed, lost or stolen and which have been replaced
         or paid as provided in Section 3.6, (iii) Coupons appertaining to
         Securities of such series called for redemption and maturing after the
         relevant Redemption Date whose surrender has been waived as provided in
         Section 11.6, and (iv) Securities and Coupons of such series for whose
         payment money has theretofore been deposited in trust or segregated and
         held in trust by the Company and thereafter repaid to the

                                       41
<PAGE>   48

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

                  (b) all Securities of such series and, in the case of (i) or
         (ii) below, any Coupons appertaining thereto 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, or (iii) if redeemable at the option of the Company, 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 (i), (ii) or (iii) above, has deposited or caused to be
         deposited with the Trustee as trust funds in trust for such purpose,
         money in the Currency in which such Securities are payable in an amount
         sufficient to pay and discharge the entire indebtedness on such
         Securities and any Coupons appertaining thereto not theretofore
         delivered to the Trustee for cancellation, including the principal of,
         any premium and interest on, and any Additional Amounts with respect to
         such Securities and any Coupons appertaining thereto, to the date of
         such deposit (in the case of Securities which have become due and
         payable) or to the Maturity thereof, as the case may be;

         (2) the Company has paid or caused to be paid all other sums payable
hereunder by the Company with respect to the Outstanding Securities of such
series and any Coupons appertaining thereto; and

         (3) the Company has delivered to the Trustee an Officer's Certificate
and an Opinion of Counsel, each stating that all conditions precedent herein
provided for relating to the satisfaction and discharge of this Indenture as to
such series have been complied with, including (in the Officer's Certificate
only) the sufficiency of any moneys deposited in connection therewith.

         In the event there are Securities of two or more series hereunder, the
Trustee shall be required to execute an instrument acknowledging satisfaction
and discharge of this Indenture only if requested to do so with respect to
Securities of such series as to which it is Trustee and if the other conditions
thereto are met.

         Notwithstanding the satisfaction and discharge of this Indenture with
respect to any series of Securities, the obligations of the Company to the
Trustee under Section 6.7 and, if money shall have been deposited with the
Trustee pursuant to subclause (b) of clause (1) of this section, the obligations
of the Company and the Trustee with respect to the Securities of such series
under Sections 3.5, 3.6, 4.3, 10.2 and 10.3, with respect to the payment of
Additional Amounts, if any, with respect to such Securities as contemplated by
Section 10.4 (but only to the extent that the Additional Amounts payable with
respect to such Securities exceed the amount deposited in respect of such
Additional Amounts pursuant to Section 4.1(1)(b)), and with respect to any
rights to convert or exchange such Securities into securities of the Company or
another issuer shall survive.

         4.2  DEFEASANCE AND COVENANT DEFEASANCE.

         (1) Unless pursuant to Section 3.1, either or both of (i) defeasance of
the Securities of or within a series under clause (2) of this Section 4.2 shall
not be applicable with respect to the Securities of such series or (ii) covenant
defeasance of the Securities of or within a series under Section 4.2(3) shall
not be applicable with respect to the Securities of such series, then such
provisions, together with the other provisions of this Section 4.2 (with such
modifications thereto as may be specified pursuant to Section 3.1 with respect
to any Securities), shall be applicable to such Securities and any Coupons
appertaining thereto, and the Company may at its option by Board Resolution, at
any time, with respect to such Securities and any Coupons appertaining thereto,
elect to have Section 4.2(2) or Section 4.2(3) be applied to such Outstanding
Securities and any Coupons appertaining thereto upon compliance with the
conditions set forth below in this Section 4.2.

         (2) Upon the Company's exercise of the above option applicable to this
Section 4.2(2) with respect to any Securities of or within a series, the Company
shall be deemed to have been discharged from its obligations with respect to
such Outstanding Securities and any Coupons appertaining thereto on the date the
conditions set forth in clause (4) of this Section 4.2 are satisfied
(hereinafter, "defeasance"). For this purpose, such defeasance means that the
Company shall be deemed to have paid and discharged the entire Indebtedness
represented by such Outstanding Securities and any Coupons appertaining thereto,
which shall thereafter be deemed to be "Outstanding" only for the purposes of
clause (5) of this Section 4.2 and the other Sections of this Indenture referred
to in clauses (i) and (ii) below, and to have satisfied all of its other
obligations under such Securities and any Coupons appertaining thereto, and this
Indenture insofar as such Securities and any Coupons appertaining thereto are
concerned (and the Trustee, at the expense of the Company, shall execute proper
instruments acknowledging the same), except for the following which shall
survive until otherwise terminated or discharged hereunder: (i) the rights of
Holders of such Outstanding Securities and any Coupons appertaining thereto to
receive, solely from the trust fund described in clause (4) of this Section 4.2
and as more fully set forth in such clause, payments in respect of the principal
of (and premium, if any) and interest, if any, on, and Additional Amounts, if
any, with respect to, such Securities and any Coupons appertaining thereto when
such payments are due, and any rights of such Holder to convert such Securities
into other securities of the Company or exchange such Securities for securities
of another issuer, (ii) the obligations of the Company and the Trustee with
respect to such Securities under Sections 3.5, 3.6, 4.3, 10.2 and 10.3 and with
respect to the payment of Additional Amounts, if any, on such Securities as
contemplated by Section 10.4 (but only to the extent that the Additional Amounts
payable with respect to such Securities exceed the amount deposited in respect
of such Additional Amounts pursuant to Section 4.2(4)(a) below), and with
respect to any rights to convert such Securities into other securities of the
Company or exchange such Securities for securities of another issuer, (iii) the
rights, powers, trusts, duties and immunities of the Trustee hereunder and (iv)
this Section 4.2. The Company may exercise its option under this Section 4.2(2)
notwithstanding the prior exercise of its option under clause (3) of this
Section 4.2 with respect to such Securities and any Coupons appertaining
thereto.

                                       43
<PAGE>   50

         (3) Upon the Company's exercise of the option to have this Section
4.2(3) apply with respect to any Securities of or within a series, the Company
shall be released from its obligations under Sections 10.5 and 10.6, and, to the
extent specified pursuant to Section 3.1(19), any other covenant applicable to
such Securities, with respect to such Outstanding Securities and any Coupons
appertaining thereto, on and after the date the conditions set forth in clause
(4) of this Section 4.2 are satisfied (hereinafter, "covenant defeasance"), and
such Securities and any Coupons appertaining thereto shall thereafter be deemed
to be not "Outstanding" for the purposes of any direction, waiver, consent or
declaration or Act of Holders (and the consequences of any thereof) in
connection with any such covenant, but shall continue to be deemed "Outstanding"
for all other purposes hereunder. For this purpose, such covenant defeasance
means that, with respect to such Outstanding Securities and any Coupons
appertaining thereto, the Company may omit to comply with, and shall have no
liability in respect of, any term, condition or limitation set forth in any such
section or such other covenant, whether directly or indirectly, by reason of any
reference elsewhere herein to any such section or such other covenant or by
reason of reference in any such section or such other covenant to any other
provision herein or in any other document and such omission to comply shall not
constitute a default or an Event of Default under Section 5.1(4) or 5.1(8) or
otherwise, as the case may be, but, except as specified above, the remainder of
this Indenture and such Securities and Coupons appertaining thereto shall be
unaffected thereby.

         (4) The following shall be the conditions to application of clause (2)
or (3) of this Section 4.2 to any Outstanding Securities of or within a series
and any Coupons appertaining thereto:

                  (a) The Company shall irrevocably have deposited or caused to
         be deposited with the Trustee as trust funds in trust for the purpose
         of making the following payments, specifically pledged as security for,
         and dedicated solely to, the benefit of the Holders of such Securities
         and any Coupons appertaining thereto, (1) an amount in Dollars or in
         such Foreign Currency in which such Securities and any Coupons
         appertaining thereto are then specified as payable at Stated Maturity,
         or (2) Government Obligations applicable to such Securities and Coupons
         appertaining thereto (determined on the basis of the Currency in which
         such Securities and Coupons appertaining thereto are then specified as
         payable at Stated Maturity) which through the scheduled payment of
         principal and interest in respect thereof in accordance with their
         terms will provide, not later than one day before the due date of any
         payment of principal of (and premium, if any) and interest, if any, on
         such Securities and any Coupons appertaining thereto, money in an
         amount, or (3) a combination thereof, in any case, in an amount,
         sufficient, without consideration of any reinvestment of such principal
         and interest, in the opinion of a nationally recognized firm of
         independent public accountants expressed in a written certification
         thereof delivered to the Trustee (on which the Trustee shall be fully
         protected in relying upon), to pay and discharge, and which shall
         be applied by the Trustee (or other qualifying trustee) to pay and
         discharge, (y) the principal of (and premium, if any) and interest, if
         any, on such Outstanding Securities and any Coupons appertaining
         thereto at the Stated Maturity of such principal or installment of

                                       44
<PAGE>   51

         principal or premium or interest and (z) any mandatory sinking fund
         payments or analogous payments applicable to such Outstanding
         Securities and any Coupons appertaining thereto on the days on which
         such payments are due and payable in accordance with the terms of this
         Indenture and of such Securities and any Coupons appertaining thereto.

                  (b) Such defeasance or covenant defeasance shall not result in
         a breach or violation of, or constitute a default under, this Indenture
         or any other material agreement or instrument to which the Company is a
         party or by which it is bound.

                  (c) No Event of Default or event which with notice or lapse of
         time or both would become an Event of Default with respect to such
         Securities and any Coupons appertaining thereto shall have occurred and
         be continuing on the date of such deposit and, with respect to
         defeasance only, at any time during the period ending on the 123rd day
         after the date of such deposit (it being understood that this condition
         shall not be deemed satisfied until the expiration of such period).

                  (d) In the case of an election under clause (2) of this
         Section 4.2, the Company shall have delivered to the Trustee an Opinion
         of Counsel stating that (i) the Company has received from the Internal
         Revenue Service a letter ruling, or there has been published by the
         Internal Revenue Service a Revenue Ruling, or (ii) since the date of
         execution of this Indenture, there has been a change in the applicable
         Federal income tax law, in either case to the effect that, and based
         thereon such opinion shall confirm that, the Holders of such
         Outstanding Securities and any Coupons appertaining thereto will not
         recognize income, gain or loss for Federal income tax purposes as a
         result of such defeasance and will be subject to Federal income tax on
         the same amounts, in the same manner and at the same times as would
         have been the case if such defeasance had not occurred.

                  (e) In the case of an election under clause (3) of this
         Section 4.2, the Company shall have delivered to the Trustee an Opinion
         of Counsel to the effect that the Holders of such Outstanding
         Securities and any Coupons appertaining thereto will not recognize
         income, gain or loss for Federal income tax purposes as a result of
         such covenant defeasance and will be subject to Federal income tax on
         the same amounts, in the same manner and at the same times as would
         have been the case if such covenant defeasance had not occurred.

                  (f) The Company shall have delivered to the Trustee an Opinion
         of Counsel to the effect that, after the 123rd day after the date of
         deposit, all money and Government Obligations (or other property as may
         be provided pursuant to Section 3.1) (including the proceeds thereof)
         deposited or caused to be deposited with the Trustee (or other
         qualifying trustee) pursuant to this clause (4) to be held in trust
         will not be subject to any case or proceeding (whether voluntary or
         involuntary) in respect of the Company under any Federal or State
         bankruptcy, insolvency, reorganization or other similar law, or any
         decree or order for relief in respect of the Company issued in
         connection therewith.

<PAGE>   52

                  (g) The Company shall have delivered to the Trustee an
         Officer's Certificate and the Company shall have delivered to the
         Trustee an Opinion of Counsel, each satisfactory to the Trustee stating
         that all conditions precedent to the defeasance or covenant defeasance
         under clause (2) or (3) of this Section 4.2 (as the case may be) and
         (in the Officer's Certificate only) this Section 4.2(4) have been
         complied with.

                  Notwithstanding any other provisions of this Section 4.2(4),
         such defeasance or covenant defeasance shall be effected in compliance
         with any additional or substitute terms, conditions or limitations
         which may be imposed on the Company in connection therewith pursuant to
         Section 3.1.

         (5) Unless otherwise specified in or pursuant to this Indenture or any
Security, if, after a deposit referred to in Section 4.2(4)(a) has been made,
(a) the Holder of a Security in respect of which such deposit was made is
entitled to, and does, elect pursuant to Section 3.1 or the terms of such
Security to receive payment in a Currency other than that in which the deposit
pursuant to Section 4.2(4)(a) has been made in respect of such Security, or (b)
a Conversion Event occurs in respect of the Foreign Currency in which the
deposit pursuant to Section 4.2(4)(a) has been made, the indebtedness
represented by such Security and any Coupons appertaining thereto shall be
deemed to have been, and will be, fully discharged and satisfied through the
payment of the principal of (and premium, if any), and interest, if any, on, and
Additional Amounts, if any, with respect to, such Security as the same becomes
due out of the proceeds yielded by converting (from time to time as specified
below in the case of any such election) the amount or other property deposited
in respect of such Security into the Currency in which such Security becomes
payable as a result of such election or Conversion Event based on (x) in the
case of payments made pursuant to clause (a) above, the applicable market
exchange rate for such Currency in effect on the second Business Day prior to
each payment date, or (y) with respect to a Conversion Event, the applicable
market exchange rate for such Foreign Currency in effect (as nearly as feasible)
at the time of the Conversion Event.

                  The Company shall pay and indemnify the Trustee against any
         tax, fee or other charge, imposed on or assessed against the Government
         Obligations deposited pursuant to this Section 4.2 or the principal or
         interest received in respect thereof other than any such tax, fee or
         other charge which by law is for the account of the Holders of such
         Outstanding Securities and any Coupons appertaining thereto.

         Anything in this Section 4.2 to the contrary notwithstanding, the
Trustee shall deliver or pay to the Company from time to time upon Company
Request and receipt of an Officer's Certificate, any money or Government
Obligations (or other property and any proceeds therefrom) held by it as
provided in clause (4) of this Section 4.2 which, in the opinion of a nationally
recognized firm of independent public accountants expressed in a written
certification thereof delivered to the Trustee (on which the Trustee shall be
fully protected in relying upon), are in excess of the amount

                                       46
<PAGE>   53

thereof which would then be required to be deposited to effect a defeasance or
covenant defeasance, as applicable, in accordance with this Section 4.2.

         4.3  APPLICATION OF TRUST MONEY.

         Subject to the provisions of the last paragraph of Section 10.3, all
money and Government Obligations (or other property as may be provided pursuant
to Section 3.1) (including the proceeds thereof) deposited with the Trustee
pursuant to Section 4.1 or 4.2 in respect of any Outstanding Securities of any
series and any Coupons appertaining thereto shall be held in trust and applied
by the Trustee, in accordance with the provisions of such Securities and any
Coupons appertaining thereto and this Indenture, to the payment, either directly
or through any Paying Agent (excluding the Company) as the Trustee may
determine, to the Holders of such Securities and any Coupons appertaining
thereto of all sums due and to become due thereon in respect of principal (and
premium, if any) and interest and Additional Amounts, if any; but such money and
Government Obligations need not be segregated from other funds except to the
extent required by law.

aggregate, result in such Indebtedness in principal amount of $40,000,000 or
more becoming or being declared due and payable prior to the date on which it
would otherwise become due and payable, and such default shall not be cured or
such acceleration shall not be rescinded, stayed or annulled or, in the case of
Indebtedness contested in good faith by the Company, a bond, letter of credit,

Indenture with respect to Securities of such series.

         5.2  ACCELERATION OF MATURITY; RESCISSION AND ANNULMENT.

         If an Event of Default with respect to Securities of any series at the
time Outstanding (other than an Event of Default specified in clause (6) or (7)
of Section 5.1) occurs and is continuing, then the Trustee or the Holders of not
less than 25% in principal amount of the Outstanding Securities of such series
may declare the principal of all the Securities of such series, or such lesser
amount as may be provided for in the Securities of such series, to be due and
payable immediately, by a notice in writing to the Company (and to the Trustee
if given by the Holders), and upon any such declaration such principal or such
lesser amount shall become immediately due and payable.

         If an Event of Default specified in clause (6) or (7) of Section 5.1
occurs, all unpaid principal of and accrued interest on the Outstanding
Securities of that series (or such lesser amount as may be provided for in the
Securities of such series) shall ipso facto become and be immediately due and
payable without any declaration or other act on the part of the Trustee or any
Holder of any Security of that series.

         At any time after a declaration of acceleration with respect to the
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 not less than a majority in principal amount of
the Outstanding Securities of such 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 of money
sufficient to pay:

                                       49
<PAGE>   56

                  (a) all overdue installments of any interest on and Additional
         Amounts with respect to all Securities of such series and any Coupon
         appertaining thereto,

                  (b) the principal of and any premium on any Securities of such
         series which have become due otherwise than by such declaration of
         acceleration and interest thereon and any Additional Amounts with
         respect thereto at the rate or rates borne by or provided for in such
         Securities,

                  (c) to the extent that payment of such interest or Additional
         Amounts is lawful, interest upon overdue installments of any interest
         and Additional Amounts at the rate or rates borne by or provided for in
         such Securities, and

                  (d) all sums paid or advanced by the Trustee hereunder and the
         reasonable compensation, expenses, disbursements and advances of the
         Trustee, its agents and counsel and all other amounts due the Trustee
         under Section 6.7; and

         (2) all Events of Default with respect to Securities of such series,
other than the non- payment of the principal of, any premium and interest on,
and any Additional Amounts with respect to Securities of such series which shall
have become due solely by such declaration of acceleration, shall have been
cured or waived as provided in Section 5.13.

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

         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 on or
any Additional Amounts with respect to any Security or any Coupon appertaining
thereto when such interest or Additional Amounts shall have become due and
payable and such default continues for a period of 30 days, or

         (2) default is made in the payment of the principal of or any premium
on any Security or any Additional Amounts with respect thereto at their
Maturity, the Company shall, upon demand of the Trustee, pay to the Trustee, for
the benefit of the Holders of such Securities and any Coupons appertaining
thereto, the whole amount of money then due and payable with respect to such
Securities and any Coupons appertaining thereto, with interest upon the overdue
principal, any premium and, to the extent that payment of such interest shall be
legally enforceable, upon any overdue installments of interest and Additional
Amounts at the rate or rates borne by or provided for in such Securities, and,
in addition thereto, such further amount of money as shall be sufficient to

                                       50
<PAGE>   57

cover the costs and expenses of collection, including the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel and all other amounts due to the Trustee under Section 6.7.

         If the Company fails to pay the money it is required to pay the Trustee
pursuant to the preceding paragraph forthwith upon the demand of the Trustee,
the Trustee, in its own name and as trustee of an express trust, may institute a
judicial proceeding for the collection of the money 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 any Coupons
appertaining thereto 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 such Securities and any Coupons appertaining thereto, 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
and any Coupons appertaining thereto 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 such Securities or in aid of the exercise of any power granted
herein or therein, or to enforce any other proper remedy.

         5.4  TRUSTEE MAY FILE PROOFS OF CLAIM.

         In case of the pendency of any receivership, insolvency, liquidation,
bankruptcy, reorganization, arrangement, adjustment, composition or other
judicial proceeding relative to the Company or any other obligor upon the
Securities of any series or the property of the Company or such other obligor or
their creditors, the Trustee (irrespective of whether the principal of the
Securities 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 any overdue principal, premium, interest or
Additional Amounts) shall be entitled and empowered, by intervention in such
proceeding or otherwise,

         (1) to file and prove a claim for the whole amount, or such lesser
amount as may be provided for in the Securities of any applicable series, of the
principal and any premium, interest and Additional Amounts owing and unpaid in
respect of the Securities and any Coupons appertaining thereto and to file such
other papers or documents as may be necessary or advisable in order to have the
claims of the Trustee (including any claim for the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents or counsel) and
of the Holders of Securities or any Coupons appertaining thereto allowed in such
judicial proceeding, and

         (2) to collect and receive any monies or other property payable or
deliverable on any such claims and to distribute the same; and any custodian,
receiver, assignee, trustee, liquidator, sequestrator or other similar official
in any such judicial proceeding is hereby authorized by each

                                       51
<PAGE>   58

Holder of Securities or any Coupons to make such payments to the Trustee and, in
the event that the Trustee shall consent to the making of such payments directly
to the Holders of Securities or any Coupons, to pay to the Trustee any amount
due to it for the reasonable compensation, expenses, disbursements and advances
of the Trustee, its agents and counsel and any other amounts due the Trustee
under Section 6.7.

         Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Holder of a Security
or any Coupon any plan of reorganization, arrangement, adjustment or composition
affecting the Securities or Coupons or the rights of any Holder thereof, or to
authorize the Trustee to vote in respect of the claim of any Holder of a
Security or any Coupon in any such proceeding.

         5.5 TRUSTEE MAY ENFORCE CLAIMS WITHOUT POSSESSION OF SECURITIES OR
COUPONS.

         All rights of action and claims under this Indenture or any of the
Securities or Coupons may be prosecuted and enforced by the Trustee without the
possession of any of the Securities or Coupons 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 or judgment, after provision for the payment of the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel, shall be for the ratable benefit of each and every Holder of the
Securities or Coupons in respect of which such judgment has been recovered.

         5.6  APPLICATION OF MONEY COLLECTED.

         Any money collected by the Trustee 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 on account of principal, or any
premium, interest or Additional Amounts, upon presentation of the Securities or
Coupons, or both, as the case may be, 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;

                  SECOND: To the payment of the amounts then due and unpaid upon
         the Securities and any Coupons for principal and any premium, interest
         and Additional Amounts 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 aggregate amounts due and payable on such
         Securities and Coupons for principal and any premium, interest and
         Additional Amounts, respectively; and

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

                                       52
<PAGE>   59

         5.7  LIMITATIONS ON SUITS.

         No Holder of any Security of any series or any Coupons appertaining
thereto shall have any right to institute any proceeding, judicial or otherwise,
with respect to this Indenture, or for the appointment of a receiver or trustee,
or for any other remedy hereunder, unless:

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

         (2) the Holders of not less than 25% in principal amount of the
Outstanding Securities of such 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 such indemnity
as is reasonably satisfactory to it against the costs, expenses and liabilities
to be incurred in compliance with such request;

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

         (5) no direction inconsistent with such written request has been given
to the Trustee during such 60-day period by the Holders of a majority in
principal amount of the Outstanding Securities of such 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 of, any
provision of this Indenture or any Security to affect, disturb or prejudice the
rights of any other such Holders or Holders of Securities of any other series,
or to obtain or to seek to obtain priority or preference over any other Holders
or to enforce any right under this Indenture, except in the manner herein
provided and for the equal and ratable benefit of all such Holders.

         5.8 UNCONDITIONAL RIGHT OF HOLDERS TO RECEIVE PRINCIPAL AND ANY
PREMIUM, INTEREST AND ADDITIONAL AMOUNTS.

         Notwithstanding any other provision in this Indenture, the Holder of
any Security or Coupon shall have the right, which is absolute and
unconditional, to receive payment of the principal of, any premium and (subject
to Sections 3.5 and 3.7) interest on, and any Additional Amounts with respect
to, such Security or payment of such Coupon, as the case may be, on the
respective Stated Maturity or Maturities therefor specified in such Security or
Coupon (or, in the case of redemption, on the Redemption Date or, in the case of
repayment at the option of such Holder if provided in or pursuant to this
Indenture, on the date such repayment is due) and to institute suit for the
enforcement of any such payment, and such right shall not be impaired without
the consent of such Holder.

                                       53
<PAGE>   60

         5.9  RESTORATION OF RIGHTS AND REMEDIES.

         If the Trustee or any Holder of a Security or a Coupon has instituted
any proceeding to enforce any right or remedy under this Indenture and such
proceeding has been discontinued or abandoned for any reason, or has been
determined adversely to the Trustee or to such Holder, then and in every such
case the Company, the Trustee and each such Holder 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 and each such Holder shall continue as though no such proceeding had
been instituted.

         5.10  RIGHTS AND REMEDIES CUMULATIVE.

         Except as otherwise provided with respect to the replacement or payment
of mutilated, destroyed, lost or stolen Securities or Coupons in the last
paragraph of Section 3.6, no right or remedy herein conferred upon or reserved
to the Trustee or to each and every Holder of a Security or a Coupon is intended
to be exclusive of any other right or remedy, and every right and remedy, to the
extent permitted by law, shall 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, to the extent permitted by law, prevent the
concurrent assertion or employment of any other appropriate right or remedy.

         5.11  DELAY OR OMISSION NOT WAIVER.

         No delay or omission of the Trustee or of any Holder of any Security or
Coupon to exercise any right or remedy accruing upon any Event of Default shall
impair any such right or remedy or constitute a waiver of any such Event of
Default or an acquiescence therein. Every right and remedy given by this Article
or by law to the Trustee or to any Holder of a Security or a Coupon may be
exercised from time to time, and as often as may be deemed expedient, by the
Trustee or by such Holder, as the case may be.

         5.12  CONTROL BY HOLDERS OF SECURITIES.

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

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

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

                                       54
<PAGE>   61

         (3) such direction is not unduly prejudicial to the rights of the other
Holders of Securities of such series not joining in such action.

         5.13  WAIVER OF PAST DEFAULTS.

         The Holders of not less than a majority in principal amount of the
Outstanding Securities of any series on behalf of the Holders of all the
Securities of such series and any Coupons appertaining thereto may waive any
past default hereunder with respect to such series and its consequences, except
a default:

         (1) in the payment of the principal of, any premium or interest on, or
any Additional Amounts with respect to, any Security of such series or any
Coupons appertaining thereto, or

         (2) in respect of a covenant or provision hereof which under Article 9
cannot be modified or amended without the consent of the Holder of each
Outstanding Security of such series affected.

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

         5.14  WAIVER OF USURY, STAY OR EXTENSION LAWS.

         The Company covenants that (to the extent that it may lawfully do so)
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 expressly waives (to the
extent that it may lawfully do so) 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.

         5.15  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 5.15 shall not apply to any suit instituted by the Trustee, to
any suit instituted by any Holder, or group of Holders, holding in the aggregate
more than 10% in principal amount of

                                       55
<PAGE>   62

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, if any, on or Additional Amounts, if any, with respect to any Security
on or after the respective Stated Maturities expressed in such Security (or, in
the case of redemption, on or after the Redemption Date, and, in the case of
repayment, on or after the date for repayment) or for the enforcement of the
right, if any, to convert or exchange any Security into other securities in
accordance with its terms.

                                    ARTICLE 6

                                   THE TRUSTEE
                                   -----------

         6.1  CERTAIN DUTIES AND RESPONSIBILITIES.

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

                  (a) 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

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

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

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

                  (a) this paragraph (3) shall not be construed to limit the
         effect of paragraph (1) of this Section 6.1;

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

                                       56
<PAGE>   63

                  (c) the Trustee shall not be liable with respect to any action
         taken or omitted to be taken by it in good faith in accordance with the
         direction of the Holders of a majority in principal amount of the
         Outstanding Securities 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.

         6.2  CERTAIN RIGHTS OF TRUSTEE.

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

         (2) any request or direction of the Company mentioned herein shall be
sufficiently evidenced by a Company Request or a Company Order (in each case,
other than delivery of any Security, together with any Coupons appertaining
thereto, to the Trustee for authentication and delivery pursuant to Section 3.3
which shall be sufficiently evidenced as provided therein) and any resolution of
the Board of Directors may be sufficiently evidenced by a Board Resolution;

         (3) 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
shall be herein specifically prescribed) may, in the absence of bad faith on its
part, may request and rely upon an Officer's Certificate;

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

         (5) the Trustee shall be under no obligation to exercise any of the
rights or powers vested in it by or pursuant to this Indenture at the request or
direction of any of the Holders of Securities of any series or any Coupons
appertaining thereto pursuant to this Indenture, unless such Holders shall have
offered to the Trustee such security or indemnity as is reasonably satisfactory
to it against the costs, expenses and liabilities which might be incurred by it
in compliance with such request or direction;

         (6) the Trustee shall not be bound to ascertain or inquire as to the
observance or performance of any covenants, agreements or obligations on behalf
of the Company or to analyze make any investigation into the
facts or matters stated in any resolution, certificate, statement, instrument,
opinion, report, notice, request, direction, consent, order, bond, debenture,
coupon or other paper or document, but the Trustee, in its discretion, may, but
shall not be obligated to make such further inquiry or

                                       57
<PAGE>   64

investigation into such facts or matters as it may see fit, and, if the Trustee
shall determine to make such further inquiry or investigation, it shall be
entitled to examine, during business hours and upon reasonable notice, the
books, records and premises of the Company, personally or by agent or attorney
and shall be entitled to terminate such further inquiry or investigation at any
time for any reason or for no reason;

         (7) 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 gross
negligence on the part of any agent or attorney appointed with due care by it
hereunder;

         (8) the Authenticating Agent, Paying Agent, and Security Registrar
shall have the same protections as the Trustee set forth hereunder;

         (9) 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;

         (10) 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
Article 6;

         (11) the Trustee shall not be liable for any action taken or omitted to
be taken by it in good faith that it believed to be authorized or within the
discretion or rights or powers conferred upon it by this Indenture, unless the
Trustee's conduct constitutes willful misconduct or gross negligence;

         (12) the permissive rights of the Trustee to do things enumerated in
this Indenture shall not be construed as a duty unless so specified; and

         (13) the Trustee shall not be deemed to have notice or actual knowledge
of any Event of Default unless a Responsible Officer of the Trustee has actual
knowledge thereof or unless written notice of any Event of Default is received
by the Trustee pursuant to Section 1.5 hereof. The Trustee shall not be bound to
ascertain or inquire as to the performance or observance of any of the terms,
conditions, covenants or agreements herein or in any series of Securities. The
Trustee, any Security Registrar, any Paying Agent and any Authenticating Agent,
their affiliates and any directors, officers, employees or agents thereof, in
good faith, may become owners of any Securities and may sell to the Company and
its affiliates any Government Obligations or other investments with the same
rights that it or they would have hereunder if the Trustee, the Security
Registrar, Paying Agents or Authenticating Agents did not serve in those
capacities.

         6.3  NOTICE OF DEFAULT.

         Within 90 days after 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 entitled to receive reports pursuant to
Section 7.3(3), notice of such default hereunder actually known to a Responsible
Officer of the Trustee, 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, if any, on, or Additional
Amounts or any sinking fund or purchase fund installment with respect to, any
Security of such series, the Trustee shall be fully protected in withholding
such notice if

                                       58
<PAGE>   65

and so long as the board of directors, the executive committee or a trust
committee of directors and/or Responsible Officers of the Trustee in good faith
determine that the withholding of such notice is in the best interest of the
Holders of Securities and Coupons of such series; and provided, further, that in
the case of any default of the character specified in Section 5.1(5) with
respect to Securities of such series, no such notice to Holders shall be given
until at least 30 days after the occurrence thereof. For the purposes of this
Section, the term "default" means any event which is, or after notice or lapse
of time or both would become, an Event of Default with respect to Securities of
such series.

         6.4  NOT RESPONSIBLE FOR RECITALS OR ISSUANCE OF SECURITIES.

         The recitals contained herein and in the Securities, except the
Trustee's certificate of authentication, and in any Coupons 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 or the Coupons, except that the Trustee represents that it is duly
authorized to execute and deliver this Indenture, authenticate the Securities
and perform its obligations hereunder and that the statements made by it in a
Statement of Eligibility on Form T-1 supplied to the Company are true and
accurate in all material respects, subject to the qualifications set forth
therein. 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. The Trustee shall have no duty or responsibility to examine or review
and shall have no liability for the contents of any document submitted or
delivered to any Holder in the nature of a preliminary or final placement
memorandum, official statement, offering circular, prospectus, registration
statement or other similar disclosure document.

         6.5  MAY HOLD SECURITIES.

         The Trustee, any Authenticating Agent, any Paying Agent, any Security
Registrar or any other Person that may be an agent of the Trustee or the
Company, in its individual or any other capacity, may become the owner or
pledgee of Securities or Coupons and, subject to Sections 310(b) and 311 of the
Trust Indenture Act, may otherwise deal with the Company with the same rights it
would have if it were not the Trustee, Authenticating Agent, Paying Agent,
Security Registrar or such other Person.

         6.6  MONEY HELD IN TRUST.

         Except as provided in Section 4.3 and Section 10.3, money held by the
Trustee in trust hereunder need not be segregated from other funds except to the
extent required by law and shall be held uninvested. The Trustee shall be under
no liability for interest on any money received by it hereunder except as
otherwise agreed to in writing with the Company.

         6.7  COMPENSATION AND REIMBURSEMENT.

         The Company agrees:

                                       59
<PAGE>   66

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

         (2) except as otherwise expressly provided herein, to reimburse the
Trustee upon its request for all reasonable expenses, disbursements and advances
incurred or made by the Trustee in accordance with any provision of this
Indenture or arising out of or in connection with the acceptance or
administration of the trust or trusts hereunder (including the reasonable
compensation and the expenses and disbursements of its agents and counsel and
other persons not regularly in its employ),
except any such expense, disbursement or advance as may be attributable to the
Trustee's gross negligence or bad faith; and

         (3) to indemnify the Trustee and its agents, officers, directors and
employees for, and to hold them harmless against, any loss, liability, claim,
damage, fine, penalty and expense to the extent incurred without gross

a Board Resolution, shall promptly appoint a successor Trustee or Trustees with

Trustee, the successor Trustee so appointed shall, forthwith upon its acceptance
of such appointment in accordance with the applicable requirements of Section

Securities of such series and the address of its Corporate Trust Office.

         (7) In no event shall any retiring Trustee be liable for the acts or
omissions of any successor Trustee hereunder.

         6.10  ACCEPTANCE OF APPOINTMENT BY SUCCESSOR.

         (1) Upon the appointment hereunder of any successor Trustee with
respect to all Securities, such successor Trustee so appointed shall execute,
acknowledge and deliver to the Company and the retiring Trustee an instrument

desirable to transfer and confirm to, and to vest in, such 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 shall add to or change any of the provisions of this
Indenture as shall be necessary to provide for or facilitate the administration
of the trusts hereunder by more than one Trustee, it being understood that
nothing herein or in such supplemental indenture shall constitute such Trustees
co-trustees of the same trust, 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 that no Trustee shall be responsible
for any notice given to, or received by, or any act or failure to act on the
part of any other Trustee hereunder, 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, such retiring Trustee
shall have no further responsibility for the exercise of rights and powers or
for the performance of the duties and obligations vested in the Trustee under
this Indenture with respect to the Securities of that or those series to which
the appointment of such successor Trustee relates other than as hereinafter
expressly set forth, 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 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 such successor Trustee, such retiring Trustee, upon

by such retiring Trustee hereunder with respect to the Securities of that or
those series to which the appointment of such successor Trustee relates, subject
to its claim, if any, provided for in Section 6.7.

         (3) Upon request of any Person appointed hereunder as a successor
Trustee, the Company shall execute any and all instruments for more fully and
certainly vesting in and confirming to such successor Trustee all such rights,
powers and trusts referred to in paragraph (1) or (2) of this Section, as the
case may be.

<PAGE>   70

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

         6.11  MERGER, CONVERSION, CONSOLIDATION OR SUCCESSION TO BUSINESS.

         Any Corporation into which the Trustee may be merged or converted or
with which it may be consolidated, or any Corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
Corporation succeeding by sale or otherwise to all or substantially all of the
corporate trust business of the Trustee shall be the successor of the Trustee
hereunder, without the execution or filing of any paper or any further act on
the part of any of the parties hereto. In case any Securities shall have been
authenticated but not delivered by the Trustee then in office, any successor by
merger, conversion or consolidation to such authenticating Trustee may adopt
such authentication and deliver the Securities so authenticated with the same
effect as if such successor Trustee had itself authenticated such Securities.
The parties hereto agree that this Section does not constitute an assumption by
the successor Trustee of any liability of the prior Trustee arising out of any
actions or inaction by the prior Trustee under the Indenture or any other
document executed in connection with the Securities.

         6.12  APPOINTMENT OF AUTHENTICATING AGENT.

         The Trustee may appoint one or more Authenticating Agents reasonably
acceptable to the Company with respect to one or more series of Securities which
shall be authorized to act on behalf of the Trustee to authenticate Securities
of that or those series issued upon original issue, exchange, registration of
transfer, partial redemption or partial repayment 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
and a certificate of authentication executed on behalf of the Trustee by an
Authenticating Agent.

         Each Authenticating Agent must be reasonably acceptable to the Company
and, except as provided in or pursuant to this Indenture, shall at all times be
a Corporation that would be permitted by the Trust Indenture Act to act as
trustee under an indenture qualified under the Trust Indenture Act, is
authorized under applicable law and by its charter to act as an Authenticating
Agent and has a combined capital and surplus (computed in accordance with
Section 310(a)(2) of the Trust Indenture Act) of at least $50,000,000. If at any
time an Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, it shall resign immediately in the manner and with
the effect specified in this Section.

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

                                       64
<PAGE>   71

such Corporation shall be otherwise eligible under this Section, without the
execution or filing of any paper or any further act on the part of the Trustee
or the Authenticating Agent.

         An Authenticating Agent may resign at any time by giving written notice
thereof to the Trustee and 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 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 reasonably acceptable to the Company and shall (i) mail
written notice of such appointment by first-class mail, postage prepaid, to all
Holders of Registered Securities, if any, of the series with respect to which
such Authenticating Agent shall serve, as their names and addresses appear in
the Security Register, and (ii) if Securities of the series are issued as Bearer
Securities, publish notice of such appointment at least once in an Authorized
Newspaper in the place where such successor Authenticating Agent has its
principal office if such office is located outside the United States. Any
successor Authenticating Agent, upon acceptance of its appointment hereunder,
shall become vested with all the rights, powers and duties of its predecessor
hereunder, with like effect as if originally named as an Authenticating Agent.
No successor Authenticating Agent shall be appointed unless eligible under the
provisions of this section.

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

         The provisions of Sections 3.3, 6.4 and 6.5 shall be applicable to each
Authenticating Agent.

         If an Authenticating Agent is appointed with respect to one or more
series of Securities pursuant to this section, the Securities of such series may
have endorsed thereon, in addition to or in lieu of the Trustee's certificate of
authentication, an alternate certificate of authentication in substantially the
following form:

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

                  CHASE MANHATTAN TRUST COMPANY, NATIONAL ASSOCIATION,

<PAGE>   72

         If all of the Securities of any series may not be originally issued at
one time, and if the Trustee does not have an office capable of authenticating
Securities upon original issuance located in a Place of Payment where the
Company wishes to have Securities of such series authenticated upon original
issuance, the Trustee, if so requested in writing (which writing need not be
accompanied by or contained in an Officer's Certificate by the Company), shall
appoint in accordance with this section an Authenticating Agent having an office
in a Place of Payment designated by the Company with respect to such series of
Securities.

and power of, the Company under the Indenture and the Securities with the same
effect as if such Surviving Entity had been named as such.

         9.2  SUPPLEMENTAL INDENTURES WITH CONSENT OF HOLDERS.

         With the consent of the Holders of not less than a majority in
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 or pursuant to a Company's 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

that no such supplemental indenture, without the consent of the Holder of each
Outstanding Security affected thereby, shall:

         (1) change the Stated Maturity of the principal of, or any premium or
installment of interest on or any Additional Amounts with respect to, any
Security, or reduce the principal amount thereof or the rate (or modify the
calculation of such rate) of interest thereon or any Additional Amounts with
respect thereto, or any premium payable upon the redemption thereof or
otherwise, or change the obligation of the Company to pay Additional Amounts
pursuant to the terms hereof (except as contemplated by Section 8.1(1) and
permitted by Section 9.1(1)), or reduce the amount of the principal of an
Original Issue Discount Security that would be due and payable upon a
declaration of acceleration of the Maturity thereof pursuant to Section 5.2 or

         (3) modify any of the provisions of this section, Section 5.13 or

         (4) make any change that adversely affects the right to convert or
exchange any Security into or for securities of the Company or other securities,

terms.

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

         It shall not be necessary for any Act of Holders of Securities 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.

         9.3  EXECUTION OF SUPPLEMENTAL INDENTURES.

         As a condition to executing, or accepting the additional trusts created
by, any supplemental indenture permitted by this Article or the modifications
thereby of the trust created by this Indenture, the Trustee shall be entitled to

protected in relying upon, an Opinion of Counsel stating that the execution of
such supplemental indenture is authorized or permitted by this Indenture and an
Officer's Certificate stating that all conditions precedent to the execution of
such supplemental indenture have been fulfilled. The Trustee may, but shall not
be obligated to, enter into any such supplemental indenture which affects the
Trustee's own rights, duties or immunities under this Indenture or otherwise.

         9.4  EFFECT OF SUPPLEMENTAL INDENTURES.

         Upon the execution of any supplemental indenture under this Article,

and of any Coupon appertaining thereto shall be bound thereby.

         9.5  REFERENCE IN SECURITIES TO SUPPLEMENTAL INDENTURES.

         Securities of any series authenticated and delivered after the
execution of any supplemental indenture pursuant to this Article may, and shall
if required by the Trustee, bear a notation in form approved by the Trustee as
to any matter provided for in such supplemental indenture. If the Company shall
so determine, new Securities of any series so modified as to conform, in the
opinion of the Trustee and the Company, to any such supplemental indenture may
be prepared and executed by the Company and authenticated and delivered by the
Trustee in exchange for Outstanding Securities of such series.

         9.6  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.

         9.7  NOTICE OF SUPPLEMENTAL INDENTURE.

         Promptly after the execution by the Company and the Trustee of any

setting forth the substance of such supplemental indenture.

                                    COVENANTS
                                    ---------

         10.1 PAYMENT OF PRINCIPAL, ANY PREMIUM, INTEREST AND ADDITIONAL
AMOUNTS.

         The Company covenants and agrees for the benefit of the Holders of the
Securities of each series that it will duly and punctually pay the principal of,
any premium and interest on and any Additional Amounts with respect to the
Securities of such series in accordance with the terms thereof, any Coupons
appertaining thereto and this Indenture. Any interest due on any Bearer Security
on or before the Maturity thereof, and any Additional Amounts payable with
respect to such interest, shall be payable only upon presentation and surrender
of the Coupons appertaining thereto for such interest as they severally mature.

         10.2  MAINTENANCE OF OFFICE OR AGENCY.

         The Company shall maintain in each Place of Payment for any series of
Securities an Office or Agency where Securities of such series (but not Bearer
Securities, except as otherwise provided below, unless such Place of Payment is
located outside the United States) may be presented or surrendered for payment,
where Securities of such series may be surrendered for registration of transfer
or exchange, where Securities of such series that are convertible or
exchangeable may be surrendered for conversion or exchange, and where notices
and demands to or upon the Company in respect of the Securities of such series
relating thereto and this Indenture may be served. If Securities of a series are
issuable as Bearer Securities, the Company shall maintain, subject to any laws
or regulations applicable thereto, an Office or Agency in a Place of Payment for
such series which is located outside the United States where Securities of such
series and any Coupons appertaining thereto may be presented and surrendered for
payment; provided, however, that if the Securities of such series are listed on
The Stock Exchange of the United Kingdom and the Republic of Ireland or the
Luxembourg Stock Exchange or any other stock exchange located outside the United
States and such stock exchange shall so require, the Company shall maintain a
Paying Agent in London, Luxembourg or any other required city located outside
the United States, as the case may

                                       73

<PAGE>   80

be, so long as the Securities of such series are listed on such exchange. The
Company will give prompt written notice to the Trustee of the location, and any
change in the location, of such Office or Agency. If at any time the Company
shall fail to maintain any such required Office or Agency or shall fail to
furnish the Trustee with the address thereof, such presentations, surrenders,
notices and demands may be made or served at the Corporate Trust Office of the
Trustee, except that Bearer Securities of such series and any Coupons
appertaining thereto may be presented and surrendered for payment at the place
specified for the purpose with respect to such Securities as provided in or
pursuant to this Indenture, and the Company hereby appoints the Trustee as its
agent to receive all such presentations, surrenders, notices and demands.

         Except as otherwise provided in or pursuant to this Indenture, no
payment of principal, premium, interest or Additional Amounts with respect to
Bearer Securities shall be made at any Office or Agency in the United States or
by check mailed to any address in the United States or by transfer to an account
maintained with a bank located in the United States; provided, however, if
amounts owing with respect to any Bearer Securities shall be payable in Dollars,
payment of principal of, any premium or interest on and any Additional Amounts
with respect to any such Security may be made at the Corporate Trust Office of
the Trustee or any Office or Agency designated by the Company in the Borough of
Manhattan, the city of New York, if (but only if) payment of the full amount of
such principal, premium, interest or Additional Amounts at all offices outside
the United States maintained for such purpose by the Company in accordance with
this Indenture is illegal or effectively precluded by exchange controls or other
similar restrictions.

         The Company may also from time to time designate one or more other
Offices or Agencies where the Securities of one or more series may be presented
or surrendered for any or all such purposes and may from time to time rescind
such designations; provided, 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 shall give prompt written notice to the Trustee of any
such designation or rescission and of any change in the location of any such
other Office or Agency. Unless otherwise provided in or pursuant to this
Indenture, the Company hereby designates as the Place of Payment for each series
of Securities the Borough of Manhattan, the city of New York, and initially
appoints the Corporate Trust Office of the Trustee as the Office or Agency of
the Company in the Borough of Manhattan, the city of New York for such purpose.
The Company may subsequently appoint a different Office or Agency in the Borough
of Manhattan, the city of New York or Cincinnati, Ohio for the Securities of any
series.

         Unless otherwise specified with respect to any Securities pursuant to
Section 3.1, if and so long as the Securities of any series (i) are denominated
in a Foreign Currency or (ii) may be payable in a Foreign Currency, or so long
as it is required under any other provision of this Indenture, then the Company
will maintain with respect to each such series of Securities, or as so required,
at least one exchange rate agent.

         10.3  MONEY FOR SECURITIES 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 shall, on or before each due date of the
principal of, any premium or interest on or Additional Amounts with respect to
any of the Securities of such series, segregate and hold in trust for the
benefit of the Persons entitled thereto a sum in the currency or currencies,
currency unit or units or composite currency or currencies in which the
Securities of such series are payable (except as otherwise specified pursuant to
Section 3.1 for the Securities of such series) sufficient to pay the principal
or any premium, interest or Additional Amounts so becoming due until such sums
shall be paid to such Persons or otherwise disposed of as herein provided, and
shall promptly notify the Trustee of its action or failure so to act.

         Whenever the Company shall have one or more Paying Agents for any
series of Securities, it shall, on or prior to each due date of the principal
of, any premium or interest on or any Additional Amounts with respect to any
Securities of such series, deposit with any Paying Agent a sum (in the currency
or currencies, currency unit or units or composite currency or currencies
described in the preceding paragraph) sufficient to pay the principal or any
premium, interest or Additional Amounts so becoming due, such sum to be held in
trust for the benefit of the Persons entitled thereto, and (unless such Paying
Agent is the Trustee) the Company will promptly notify the Trustee of its action
or failure so to act.

         The Company shall cause each Paying Agent for any series of Securities
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 shall:

         (1) hold all sums held by it for the payment of the principal of, any
premium or interest on or any Additional Amounts with respect to Securities of
such 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 provided in or
pursuant to this Indenture;

         (2) give the Trustee notice of any default by the Company (or any other
obligor upon the Securities of such series) in the making of any payment of
principal, any premium or interest on or any Additional Amounts with respect to
the Securities of such series; and

         (3) at any time during the continuance of any such default, upon the
written request of the Trustee, forthwith pay to the Trustee all sums so held in
trust by such 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 terms as those upon which such sums were held by the Company

                                       75
<PAGE>   82

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 sums.

         Except as otherwise provided herein or pursuant hereto, 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, any premium or interest on or any
Additional Amounts with respect to any Security of any series or any Coupon
appertaining thereto and remaining unclaimed for two years after such principal
or any such premium or interest or any such Additional Amounts shall have become
due and payable shall be paid to the Company on Company Request, or (if then
held by the Company) shall be discharged from such trust; and the Holder of such
Security or any Coupon appertaining thereto 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 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 any such repayment, may at the expense of the Company cause to be
published once, in an Authorized Newspaper in each Place of Payment for such
series or to be mailed to Holders of Registered Securities of such series, or
both, notice that such money remains unclaimed and that, after a date specified
therein, which shall not be less than 30 days from the date of such publication
or mailing nor shall it be later than two years after such principal and any
premium or interest or Additional Amounts shall have become due and payable, any
unclaimed balance of such money then remaining will be repaid to the Company. In
the absence of any such Company Request, the Trustee shall from time to time
deliver such unclaimed funds to or as directed by pertinent escheat authority,
as identified by the Trustee in its sole discretion, pursuant to and in
accordance with applicable unclaimed property laws, rules or regulations. Any
such delivery shall be in accordance with the customary practices and procedures
of the Trustee and the escheat authority. All moneys held by the Trustee and
subject to this Section shall be held uninvested and without liability for
interest thereon. Before making any payment under this Section 10.3, the Trustee
shall be entitled to receive at the Company's expense an Opinion of Counsel to
the effect that said payment is permitted under applicable law.

         10.4  ADDITIONAL AMOUNTS.

         If any Securities of a series provide for the payment of Additional
Amounts, the Company agrees to pay to the Holder of any such Security or any
Coupon appertaining thereto Additional Amounts as provided in or pursuant to
this Indenture or such Securities. Whenever in this Indenture there is
mentioned, in any context, the payment of the principal of or any premium or
interest on, or in respect of, any Security of any series or any Coupon or the
net proceeds received on the sale or exchange of any Security of any series,
such mention shall be deemed to include mention of the payment of Additional
Amounts provided by the terms of such series established hereby or pursuant
hereto to the extent that, in such context, Additional Amounts are, were or
would be payable in respect thereof pursuant to such terms, and express mention
of the payment of Additional Amounts (if applicable) in any provision hereof
shall not be construed as excluding Additional Amounts in those provisions
hereof where such express mention is not made.

         Except as otherwise provided in or pursuant to this Indenture or the
Securities of the applicable series, if the Securities of a series provide for
the payment of Additional Amounts, at least 10 days prior to the first Interest
Payment Date with respect to such series of Securities (or if the Securities of
such series shall not bear interest prior to Maturity, the first day on which a
payment of principal is made), and at least 10 days prior to each date of
payment of principal or interest if there has been any change with respect to
the matters set forth in the below-mentioned Officer's Certificate, the Company
shall furnish to the Trustee and the principal Paying Agent or Paying

                                       76
<PAGE>   83

Agents, if other than the Trustee, an Officer's Certificate instructing the
Trustee and such Paying Agent or Paying Agents whether such payment of principal
of and premium, if any, or interest on the Securities of such series shall be
made to Holders of Securities of such series or the Coupons appertaining thereto
who are United States Aliens without withholding for or on account of any tax,
assessment or other governmental charge described in the Securities of such
series. If any such withholding shall be required, then such Officer's
Certificate shall specify by country the amount, if any, required to be withheld
on such payments to such Holders of Securities or Coupons, and the Company
agrees to pay to the Trustee or such Paying Agent the Additional Amounts
required by the terms of such Securities. The Company covenants to indemnify the
Trustee and any Paying Agent for, and to hold them harmless against, any loss,
liability or expense reasonably incurred without gross negligence or bad faith
on their part arising out of or in connection with actions taken or omitted by
any of them in reliance on any Officer's Certificate furnished pursuant to this
Section 10.4.

         10.5  LIMITATION ON LIENS.

         The Company will not, and will not cause or permit any of its
Subsidiaries to, directly or indirectly, Incur any Liens of any kind (except for
Permitted Liens) against or upon any of their respective properties or assets,
whether owned on the date of this Indenture or acquired after the date of this
Indenture, or any proceeds therefrom, to secure any Indebtedness unless
contemporaneously therewith effective provision is made, in the case of the
Company, to secure the Securities and all other amounts due under the Indenture,
equally and ratably with such Indebtedness (or, in the event that such
Indebtedness is subordinated in right of payment to the Securities prior to such
Indebtedness) with a Lien on the same properties and assets securing such
Indebtedness for so long as such Indebtedness is secured by such Lien.

         10.6  LIMITATION UPON SALES OF CAPITAL STOCK OF SUBSIDIARIES.

         The Company will not sell, transfer or otherwise dispose of (except to
a Subsidiary, which agrees in writing to hold such transferred shares subject to
the terms of this Section 10.6), and it will not permit any Subsidiary to sell,
transfer or otherwise dispose of (except to the Company or to a Subsidiary,
which agrees in writing to hold such transferred shares subject to the terms of
this Section 10.6), any shares of Capital Stock of a Subsidiary, unless the
entire Capital Stock of such Subsidiary at the time owned by the Company and its
Subsidiaries shall be disposed of at the same time for a consideration
consisting of cash or other property, which, in the opinion of the Board of
Directors, is at least equal to the fair value thereof.

         10.7  CORPORATE EXISTENCE.

         Subject to Article 8, the Company shall do or cause to be done all
things necessary to preserve and keep in full force and effect its corporate
existence and that of each of its Subsidiaries and their respective rights
(charter and statutory) and franchises; provided, however, that the

                                       77
<PAGE>   84

foregoing shall not obligate the Company or any of its Subsidiaries to preserve
any such right or franchise if the Company or any such Subsidiary shall
determine that the preservation thereof is no longer desirable in the conduct of
its business or the business of such Subsidiary and that the loss thereof is not
disadvantageous in any material respect to any Holder.

         10.8  WAIVER OF CERTAIN COVENANTS.

         The Company may omit in any particular instance to comply with any
term, provision or condition set forth in Section 10.5, 10.6 or 10.7 with
respect to the Securities of any series if before the time for such compliance
the Holders of at least a majority in principal amount of the Outstanding
Securities of such series, by Act of such Holders, either shall waive such
compliance in such instance or generally shall have waived compliance with such
term, provision or condition, but no such waiver shall extend to or affect such
term, provision or condition except to the extent so expressly waived, and,
until such waiver shall become effective, the obligations of the Company and the
duties of the Trustee in respect of any such term, provision or condition shall
remain in full force and effect. A copy of such waiver shall be delivered to the
Trustee.

         10.9  COMPANY STATEMENT AS TO COMPLIANCE; NOTICE OF CERTAIN DEFAULTS.

end of each fiscal year, a written statement (which need not be contained in or

under this Indenture throughout such year, or, if there has been a default in

occurred and is continuing which is, or after notice or lapse of time or both
would become, an Event of Default, or, if such an event has occurred and is
continuing, specifying each such event known to him and the nature and status
thereof.

         (2) The Company shall deliver to the Trustee, within five days after
the occurrence thereof, written notice of any Event of Default or any event
which after notice or lapse of time or both would become an Event of Default
pursuant to clause (4) of Section 5.1.

         (3) The Trustee shall have no duty to monitor the Company's compliance
with the covenants contained in this Article 10 other than as specifically set
forth in this Section.

         10.10 LIMITATION ON SALE AND LEASEBACK TRANSACTIONS. So long as any of
the Securities remain outstanding, the Company will not, and will not permit any
of its Subsidiaries to, enter into

                                       78
<PAGE>   85

         or any of its Subsidiaries;

                  (2) the Company or such Subsidiary would be entitled to Incur,
         in accordance with the Indenture, Indebtedness secured by a Permitted
         Lien on the assets to be leased in an amount at least equal to the
         Attributable Debt in respect of such transaction; or

                  (3) the proceeds of the sale of the assets to be leased are at
         least equal to their Fair Market Value and the proceeds are applied to
         the purchase or acquisition (or, in the case of real property, the
         construction) of tangible assets or to the retirement (other than at
         maturity or pursuant to a mandatory sinking fund or mandatory
         redemption provision) of Indebtedness of the Company for money borrowed
         which ranks pari passu to the Securities.

                            REDEMPTION OF SECURITIES
                            ------------------------

         11.1  APPLICABILITY OF ARTICLE.

         Redemption of Securities of any series at the option of the Company as
permitted or required by the terms of such Securities shall be made in
accordance with the terms of such Securities and (except as otherwise provided
herein or pursuant hereto) this Article.

         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 of (a) less than all of the Securities of any series or (b) all
of the Securities of any series, with the same issue date, interest rate or
formula, Stated Maturity and other terms, the Company shall, at least 60 days
prior to the Redemption Date fixed by the Company (unless a shorter notice shall
be satisfactory to the Trustee), notify the Trustee of such Redemption Date and
of the principal amount of Securities of such series to be redeemed.

         11.3  SELECTION BY TRUSTEE OF SECURITIES TO BE REDEEMED.

         If less than all of the Securities of any series with the same issue
date, interest rate or formula, Stated Maturity and other terms 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

                                       79
<PAGE>   86

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 portions of the principal amount of
Registered Securities of such series; provided, however, that no such partial
redemption shall reduce the portion of the principal amount of a Registered
Security of such series not redeemed to less than the minimum denomination for a
Security of such series established herein or pursuant hereto.

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

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

         Unless otherwise specified in or pursuant to this Indenture or the
Securities of any series, if any Security selected for partial redemption is
converted into other securities of the Company or exchanged for securities of
another issuer in part before termination of the conversion or exchange right
with respect to the portion of the Security so selected, the converted portion
of such Security shall be deemed (so far as may be) to be the portion selected
for redemption. Securities which have been converted or exchanged during a
selection of Securities to be redeemed shall be treated by the Trustee as
Outstanding for the purpose of such selection.

         11.4  NOTICE OF REDEMPTION.

         Notice of redemption shall be given by the Company, or if requested by
the Company and agreed to by the Trustee, by the Trustee in the manner provided
in Section 1.6, not less than 30 nor more than 60 days prior to the Redemption
Date, unless a shorter period is specified in the Securities to be redeemed, to
the Holders of Securities to be redeemed. Failure to give notice by mailing in
the manner herein provided to the Holder of any Registered Securities designated
for redemption as a whole or in part, or any defect in the notice to any such
Holder, shall not affect the validity of the proceedings for the redemption of
any other Securities or portion thereof.

         Any notice that is mailed to the Holder of any Registered Securities in
the manner herein provided shall be conclusively presumed to have been duly
given, whether or not such Holder receives the notice.

   All notices of redemption shall state:

         (1) the Redemption Date,

         (2) the Redemption Price,

                                       80
<PAGE>   87

         (3) if less than all Outstanding Securities of any series are to be
redeemed, the identification (and, in the case of partial redemption, the
principal amount) of the particular Security or Securities to be redeemed,

         (4) in case any Security is to be redeemed in part only, the notice
which relates to such Security shall state that on and after the Redemption
Date, upon surrender of such Security, the Holder of such Security will receive,
without charge, a new Security or Securities of authorized denominations for the
principal amount thereof remaining unredeemed,

         (5) that, on the Redemption Date, the Redemption Price shall become due
and payable upon each such Security or portion thereof to be redeemed, and, if
applicable, that interest thereon shall cease to accrue on and after said date,

         (6) the place or places where such Securities, together (in the case of
Bearer Securities) with all Coupons appertaining thereto, if any, maturing after
the Redemption Date, are to be surrendered for payment of the Redemption Price
and any accrued interest and Additional Amounts pertaining thereto,

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

         (8) that, unless otherwise specified in such notice, Bearer Securities
of any series, if any, surrendered for redemption must be accompanied by all
Coupons maturing subsequent to the date fixed for redemption or the amount of
any such missing Coupon or Coupons will be deducted from the Redemption Price,
unless security or indemnity satisfactory to the Company, the Trustee and any
Paying Agent is furnished,

         (9) if Bearer Securities of any series are to be redeemed and no
Registered Securities of such series are to be redeemed, and if such Bearer
Securities may be exchanged for Registered Securities not subject to redemption
on the Redemption Date pursuant to Section 3.5 or otherwise, the last date, as
determined by the Company, on which such exchanges may be made,

         (10) in the case of Securities of any series that are convertible into
Common Stock of the Company or exchangeable for other securities, the conversion
or exchange price or rate, the date or dates on which the right to convert or
exchange the principal of the Securities of such series to be redeemed will
commence or terminate and the place or places where such Securities may be
surrendered for conversion or exchange, and

         (11) the CUSIP number or the Euroclear or the Cedel reference numbers
of such Securities, if any (or any other numbers used by a Depository to
identify such Securities).

                                       81
<PAGE>   88

         A notice of redemption published as contemplated by Section 1.6 need
not identify particular Registered Securities to be redeemed.

         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.

         11.5  DEPOSIT OF REDEMPTION PRICE.

         On or prior to any Redemption Date, the Company shall deposit, with
respect to the Securities of any series called for redemption pursuant to
Section 11.4, with the Trustee or with a Paying Agent (or, if the Company is
acting as its own Paying Agent, segregate and hold in trust as provided in
Section 10.3) an amount of money in the applicable Currency sufficient to pay
the Redemption Price of, and (except if the Redemption Date shall be an Interest
Payment Date, unless otherwise specified pursuant to Section 3.1 or in the
Securities of such series) any accrued interest on and Additional Amounts with
respect thereto, all such Securities or portions thereof which are to be
redeemed on that date.

         11.6  SECURITIES PAYABLE ON REDEMPTION DATE.

         Notice of redemption having been given as aforesaid, the Securities so
to be redeemed shall, on the Redemption Date, become due and payable at the
Redemption Price therein specified, and from and after such date (unless the
Company shall default in the payment of the Redemption Price and accrued
interest) such Securities shall cease to bear interest and the Coupons for such
interest appertaining to any Bearer Securities so to be redeemed, except to the
extent provided below, shall be void. Upon surrender of any such Security for
redemption in accordance with said notice, together with all Coupons, if any,
appertaining thereto maturing after the Redemption Date, such Security shall be
paid by the Company at the Redemption Price, together with any accrued interest
and Additional Amounts to the Redemption Date; provided, however, that, except
as otherwise provided in or pursuant to this Indenture or the Bearer Securities
of such series, installments of interest on Bearer Securities whose Stated
Maturity is on or prior to the Redemption Date shall be payable only upon
presentation and surrender of Coupons for such interest (at an Office or Agency
located outside the United States except as otherwise provided in Section 10.2),
and provided, further, that, except as otherwise specified in or pursuant to
this Indenture or the Registered Securities of such series, installments of
interest on Registered Securities whose Stated Maturity is on or prior to the
Redemption Date shall be payable to the Holders of such Securities, or one or
more Predecessor Securities, registered as such at the close of business on the
Regular Record Dates therefor according to their terms and the provisions of
Section 3.7.

         If any Bearer Security surrendered for redemption shall not be
accompanied by all appurtenant Coupons maturing after the Redemption Date, such
Security may be paid after deducting from the Redemption Price an amount equal
to the face amount of all such missing Coupons, or the

                                       82
<PAGE>   89

surrender of such missing Coupon or Coupons may be waived by the Company and the
Trustee if there be furnished to them such security or indemnity as they may
require to save each of them and any Paying Agent harmless. If thereafter the
Holder of such Security shall surrender to the Trustee or any Paying Agent any
such missing Coupon in respect of which a deduction shall have been made from
the Redemption Price, such Holder shall be entitled to receive the amount so
deducted; provided, however, that any interest or Additional Amounts represented
by Coupons shall be payable only upon presentation and surrender of those
Coupons at an Office or Agency for such Security located outside of the United
States except as otherwise provided in Section 10.2.

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

         11.7  SECURITIES REDEEMED IN PART.

         Any Registered Security which is to be redeemed only in part shall be
surrendered at any Office or Agency for such Security (with, if the Company or
the Trustee so requires, due endorsement by, or a written instrument of transfer
in form satisfactory to the Company and the Trustee duly executed by, the Holder
thereof or his attorney duly authorized in writing) and the Company shall
execute and the Trustee shall authenticate and deliver to the Holder of such
Security without service charge, a new Registered Security or Securities of the
same series, containing identical terms and provisions, of any authorized
denomination as requested by such Holder in aggregate principal amount equal to
and in exchange for the unredeemed portion of the principal of the Security so
surrendered. If a Security in global form is so surrendered, the Company shall
execute, and the Trustee shall authenticate and deliver to the U.S. Depository
or other Depository for such Security in global form as shall be specified in
the Company Order with respect thereto to the Trustee, without service charge, a
new Security in global form in a denomination equal to and in exchange for the
unredeemed portion of the principal of the Security in global form so
surrendered.

                                  -------------

         12.1  APPLICABILITY OF ARTICLE.

         The provisions of this Article shall be applicable to any sinking fund
for the retirement of Securities of a series, except as otherwise permitted or
required in or pursuant to this Indenture or any Security of such series issued
pursuant to this Indenture.

         The minimum amount of any sinking fund payment provided for by the
terms of Securities of any series is herein referred to as a "mandatory sinking
fund payment," and any payment in excess

                                       83
<PAGE>   90

of such minimum amount provided for by the terms of Securities of such series is
herein referred to as an "optional sinking fund payment". If provided for by the
terms of Securities of any series, the cash amount of any sinking fund payment
may be subject to reduction as provided in Section 12.2. Each sinking fund
payment shall be applied to the redemption of Securities of any series as
provided for by the terms of Securities of such series and this Indenture.

         12.2  SATISFACTION OF SINKING FUND PAYMENTS WITH SECURITIES.

         The Company may, in satisfaction of all or any part of any sinking fund
payment with respect to the Securities of any series to be made pursuant to the
terms of such Securities (1) deliver Outstanding Securities of such series
(other than any of such Securities previously called for redemption or any of
such Securities in respect of which cash shall have been released to the
Company), together in the case of any Bearer Securities of such series with all
unmatured Coupons appertaining thereto, and (2) apply as a credit Securities of
such series which have been redeemed either at the election of the Company
pursuant to the terms of such series of Securities or through the application of
permitted optional sinking fund payments pursuant to the terms of such
Securities, provided that such series of Securities have not been previously so
credited. Such Securities shall be received and credited for such purpose by the
Trustee at the Redemption Price specified in such Securities for redemption
through operation of the sinking fund and the amount of such sinking fund
payment shall be reduced accordingly. If, as a result of the delivery or credit
of Securities of any series in lieu of cash payments pursuant to this Section
12.2, the principal amount of Securities of such series to be redeemed in order
to satisfy the remaining sinking fund payment shall be less than $100,000, the
Trustee need not call Securities of such series for redemption, except upon
Company Request, and such cash payment shall be held by the Trustee or a Paying
Agent and applied to the next succeeding sinking fund payment, provided,
however, that the Trustee or such Paying Agent shall at the written request of
the Company from time to time pay over and deliver to the Company any cash
payment so being held by the Trustee or such Paying Agent upon delivery by the
Company to the Trustee of Securities of that series purchased by the Company
having an unpaid principal amount equal to the cash payment requested to be
released to the Company.

         12.3  REDEMPTION OF SECURITIES FOR SINKING FUND.

         Not less than 75 days prior to each sinking fund payment date for any
series of Securities, the Company shall deliver to the Trustee an Officer's
Certificate specifying the amount of the next ensuing mandatory sinking fund
payment for that series pursuant to the terms of that series, the portion
thereof, if any, which is to be satisfied by payment of cash and the portion
thereof, if any, which is to be satisfied by delivering and crediting of
Securities of that series pursuant to Section 12.2, and the optional amount, if
any, to be added in cash to the next ensuing mandatory sinking fund payment, and
will also deliver to the Trustee any Securities to be so credited and not
theretofore delivered. If such Officer's Certificate shall specify an optional
amount to be added in cash to the next ensuing mandatory sinking fund payment,
the Company shall thereupon be obligated to pay the amount therein specified.
Not less than 60 days before each such sinking fund payment date the

                                       84
<PAGE>   91
 Trustee shall select the Securities to be redeemed upon such sinking fund
payment date in the manner specified in Section 11.3 and cause notice of the
redemption thereof to be given in the name of and at the expense of the Company
in the manner provided in Section 11.4. Such notice having been duly given,
payment by the Company of the Redemption Price and any optional amount and
delivery of any such Securities, and the redemption of such Securities shall all
be made upon the terms and in the manner stated in Sections 11.6 and 11.7.

         13.1  APPLICABILITY OF ARTICLE.

         Securities of any series which are repayable at the option of the
Holders thereof before their Stated Maturity shall be repaid in accordance with
the terms of the Securities of such series. The repayment of any principal
amount of Securities pursuant to such option of the Holder to require repayment
of Securities before their Stated Maturity, for purposes of Section 3.9, shall
not operate as a payment, redemption or satisfaction of the Indebtedness
represented by such Securities unless and until the Company, at its option,
shall deliver or surrender the same to the Trustee with a directive that such
Securities be cancelled. Notwithstanding anything to the contrary contained in
this Section 13.1, in connection with any repayment of Securities, the Company
may arrange for the purchase of any Securities by an agreement with one or more
investment bankers or other purchasers to purchase such Securities by paying to
the Holders of such Securities on or before the close of business on the
repayment date an amount not less than the repayment price payable by the
Company on repayment of such Securities, and the obligation of the Company to
pay the repayment price of such Securities shall be satisfied and discharged to
the extent such payment is so paid by such purchasers.

         Whenever this Indenture provides for (i) any action by, or the
determination of any of the rights of, Holders of Securities of any series in
which not all of such Securities are denominated in the same Currency, or (ii)
any distribution to Holders of Securities, in the absence of any provision to
the contrary in the form of Security of any particular series or pursuant to
this Indenture or the Securities, any amount in respect of any Security
denominated in a Currency other than Dollars shall be treated for any such
action or distribution as that amount of Dollars that could be obtained for such
amount on such reasonable basis of exchange and as of the record date with
respect to Registered Securities of such series (if any) for such action,
determination of rights or distribution (or, if there shall be no applicable
record date, such other date reasonably proximate to the date of

                                       85

         15.1  PURPOSES FOR WHICH MEETINGS MAY BE CALLED.

         A meeting of Holders of Securities of any series may be called at any
time and from time to time pursuant to this Article to make, give or take any
request, demand, authorization, direction, notice, consent, waiver or other Act
provided by this Indenture to be made, given or taken by Holders of Securities
of such series.

         15.2  CALL, NOTICE AND PLACE OF MEETINGS.

         (1) The Trustee may at any time call a meeting of Holders of Securities
of any series for any purpose specified in Section 15.1, to be held at such time
and at such place in the Borough of Manhattan, the city of New York, or, if
Securities of such series have been issued in whole or in part as Bearer
Securities, in London or in such place outside the United States as the Trustee
shall determine. Notice of every meeting of Holders of Securities of any series,
setting forth the time and the place of such meeting and in general terms the
action proposed to be taken at such meeting, shall be given, in the manner
provided in Section 1.6, not less than 21 nor more than 180 days prior to the
date fixed for the meeting.

         (2) In case at any time the Company (by or pursuant to a Board
Resolution) or the Holders of at least 10% in principal amount of the
Outstanding Securities of any series shall have requested the Trustee to call a
meeting of the Holders of Securities of such series for any purpose specified in
Section 15.1, by written request setting forth in reasonable detail the action
proposed to be taken at the meeting, and the Trustee shall not have mailed
notice of or made the first publication of the notice of such meeting within 21
days after receipt of such request (whichever shall be required pursuant to
Section 1.6) or shall not thereafter proceed to cause the meeting to be held as
provided herein, then the Company or the Holders of Securities of such series in
the amount above specified, as the case may be, may determine the time and the
place in the Borough of Manhattan, the city of New York, or, if Securities of
such series are to be issued as Bearer Securities, in London for such meeting
and may call such meeting for such purposes by giving notice thereof as provided
in clause (1) of this section.

         15.3  PERSONS ENTITLED TO VOTE AT MEETINGS.

         To be entitled to vote at any meeting of Holders of Securities of any
series, a Person shall be (1) a Holder of one or more Outstanding Securities of

                                       86
<PAGE>   93

such series, or (2) a Person appointed by an instrument in writing as proxy for
a Holder or Holders of one or more Outstanding Securities of such series by such
Holder or Holders. The only Persons who shall be entitled to be present or to
speak at any meeting of Holders of Securities of any series shall be the Persons
entitled to vote at such meeting and their counsel, any representatives of the
Trustee and its counsel and any representatives of the Company and its counsel.

         15.4  QUORUM; ACTION.

         The Persons entitled to vote a majority in principal amount of the
Outstanding Securities of a series shall constitute a quorum for any meeting of
Holders of Securities of such series. In the absence of a quorum within 30
minutes after the time appointed for any such meeting, the meeting shall, if
convened at the request of Holders of Securities of such series, be dissolved.
In any other case the meeting may be adjourned for a period of not less than 10
days as determined by the chairman of the meeting prior to the adjournment of
such meeting. In the absence of a quorum at any reconvened meeting, such
reconvened meeting may be further adjourned for a period of not less than 10
days as determined by the chairman of the meeting prior to the adjournment of
such reconvened meeting. Notice of the reconvening of any adjourned meeting
shall be given as provided in Section 15.2(1), except that such notice need be
given only once not less than five days prior to the date on which the meeting
is scheduled to be reconvened. Notice of the reconvening of an adjourned meeting
shall state expressly the percentage, as provided above, of the principal amount
of the Outstanding Securities of such series which shall constitute a quorum.

         Except as limited by the proviso to Section 9.2, any resolution
presented to a meeting or adjourned meeting duly reconvened at which a quorum is
present as aforesaid may be adopted only by the affirmative vote of the Holders
of a majority in principal amount of the Outstanding Securities of that series;
provided, however, that, except as limited by the proviso to Section 9.2, any
resolution with respect to any request, demand, authorization, direction,
notice, consent, waiver or other Act which this Indenture expressly provides may
be made, given or taken by the Holders of a specified percentage, which is less
than a majority, in principal amount of the Outstanding Securities of a series
may be adopted at a meeting or an adjourned meeting duly reconvened and at which
a quorum is present as aforesaid by the affirmative vote of the Holders of such
specified percentage in principal amount of the Outstanding Securities of such
series.

         Any resolution passed or decision taken at any meeting of Holders of
Securities of any series duly held in accordance with this section shall be
binding on all the Holders of Securities of such series and the Coupons
appertaining thereto, whether or not such Holders were present or represented at
the meeting.

         15.5 DETERMINATION OF VOTING RIGHTS; CONDUCT AND ADJOURNMENT OF
MEETINGS.

         (1) Notwithstanding any other provisions of this Indenture, the Trustee
may make such reasonable regulations as it may deem advisable for any meeting of
Holders of Securities of such series in regard to proof of the holding of
Securities of such series and of the appointment of proxies

                                       87
<PAGE>   94

and in regard to the appointment and duties of inspectors of votes, the
submission and examination of proxies, certificates and other evidence of the
right to vote, and such other matters concerning the conduct of the meeting as
it shall deem appropriate. Except as otherwise permitted or required by any such
regulations, the holding of Securities shall be proved in the manner specified
in Section 1.4 and the appointment of any proxy shall be proved in the manner
specified in Section 1.4 or by having the signature of the person executing the
proxy witnessed or guaranteed by any trust company, bank or banker authorized by
Section 1.4 to certify to the holding of Bearer Securities. Such regulations may
provide that written instruments appointing proxies, regular on their face, may
be presumed valid and genuine without the proof specified in Section 1.4 or
other proof.

         (2) The Trustee shall, by an instrument in writing, appoint a temporary
chairman of the meeting, unless the meeting shall have been called by the
Company or by Holders of Securities as provided in Section 15.2(2), in which
case the Company or the Holders of Securities of the series calling the meeting,
as the case may be, shall in like manner appoint a temporary chairman. A
permanent chairman and a permanent secretary of the meeting shall be elected by
vote of the Persons entitled to vote a majority in principal amount of the
Outstanding Securities of such series represented at the meeting.

         (3) At any meeting, each Holder of a Security of such series or proxy
shall be entitled to one vote for each $1,000 principal amount of Securities of
such series held or represented by him; provided, however, that no vote shall be
cast or counted at any meeting in respect of any Security challenged as not
Outstanding and ruled by the chairman of the meeting to be not Outstanding. The
chairman of the meeting shall have no right to vote, except as a Holder of a
Security of such series or proxy.

         (4) Any meeting of Holders of Securities of any series duly called
pursuant to Section 15.2 at which a quorum is present may be adjourned from time
to time by Persons entitled to vote a majority in principal amount of the
Outstanding Securities of such series represented at the meeting; and the
meeting may be held as so adjourned without further notice.

         15.6  COUNTING VOTES AND RECORDING ACTION OF MEETINGS.

         The vote upon any resolution submitted to any meeting of Holders of
Securities of any series shall be by written ballots on which shall be
subscribed the signatures of the Holders of Securities of such series or of
their representatives by proxy and the principal amounts and serial numbers of
the Outstanding Securities of such series held or represented by them. The
permanent chairman of the meeting shall appoint two inspectors of votes who
shall count all votes cast at the meeting for or against any resolution and who
shall make and file with the secretary of the meeting their verified written
reports in triplicate of all votes cast at the meeting. A record, at least in
triplicate, of the proceedings of each meeting of Holders of Securities of any
series shall be prepared by the secretary of the meeting and there shall be
attached to said record the original reports of the inspectors of votes on any
vote by ballot taken thereat and affidavits by one or more persons having
knowledge of the

July 18, 2000

Mr. Robert J. Bennett
101 Marvelle Road
Fayetteville, New York  13066

Dear Mr. Bennett:

This letter agreement ("Letter Agreement") sets forth the terms and conditions
upon which you are resigning as Chairman of M&T Bank Corporation ("M&T") and
Vice Chairman of Manufacturers and Traders Trust Company ("M&T Bank"), effective
July 18, 2000. It also constitutes an amendment and supplement to the Employment
Agreement between you and M&T, dated as of April 1, 1998 (the "Employment
Agreement").

         1. RETIREMENT; CONTINUED SERVICE ON BOARDS. Upon execution of this
Letter Agreement you are hereby retiring as Chairman of M&T and Vice Chairman of
M&T Bank effective at the close of business on July 18, 2000. You agree,
however, to continue to serve at the pleasure of M&T (unless legally or
physically unable) on the Boards of Directors and Executive Committees of M&T
and M&T Bank (subject to the by-laws of M&T and M&T Bank) and as a member of the
Directors Advisory Council of the Syracuse Division of M&T Bank. You will be
entitled to receive your current base salary through July 18, 2000, payable in
accordance with M&T Bank's usual payroll practices. You will also be entitled to
a lump sum payment for your accrued but unused vacation.

         2. CONTINUED MEDICAL AND LIFE INSURANCE COVERAGE. Until you attain age
65, you will be entitled to continued medical and life insurance benefits on
terms and conditions that are at least substantially equivalent to those
provided to senior executive officers of M&T from time-to-time, except that you
will be required to directly pay your share of premium payments for medical
insurance coverage rather than paying such premiums through payroll deductions.
Upon and after attaining age 65, you will be entitled to such coverage as is
provided to retired employees of M&T under M&T's retiree medical and life
insurance plans.

         3. RETIREMENT BENEFITS. Upon your attainment of age 65, you will be
entitled to begin receiving from M&T (or one of its affiliates) an annual
retirement benefit (the "Retirement Benefit") for your life, equal to the
difference between (a) $300,000, and (b) the amount of any benefit payable to
you under any tax-qualified or nonqualified defined benefit pension or
retirement plans (collectively, the "Retirement Plans"), provided that, in
determining the amount of benefits payable to you under the Retirement

Plans, you will be deemed to have received benefit payment under each of the
Retirement Plans in the form of a 50% joint and survivor annuity for your life,
with your current spouse as the designated beneficiary. The amount of such joint
and survivor annuity payments shall be calculated using the actuarial
assumptions used under the applicable plan, or if such plan does not specify the
required actuarial assumptions, the actuarial assumptions used under the M&T
Bank Corporation Pension Plan. In the event of your death, whether before or
after attaining age 65, your current spouse, should she survive you, shall be
paid an annual benefit of 50% of the Retirement Benefit for her life. The
foregoing is intended to provide you with a total annual defined benefit
retirement payment of $300,000 and, in the event of your death, your current
surviving spouse with a total annual benefit of $150,000.

              4. VESTING OF STOCK OPTIONS. Upon the effective date of your
retirement on July 18, 2000, all outstanding employee stock options you hold
covering M&T common stock shall, to the extent not therefore vested and
exercisable, become fully vested and may be exercised in accordance with the
terms of the applicable option agreements relating to termination of employment
by reason of retirement.

              5. EMPLOYMENT AGREEMENT. The Employment Agreement shall remain in
effect, except upon your retirement on July 18, 2000, you will no longer be
employed by M&T or M&T Bank, and Section 2 (other than subsection 2 (c)) and
Sections 3 through 11 of the Employment Agreement shall no longer apply after
July 18, 2000, and shall have no legal force or effect notwithstanding anything
to the contrary in the Employment Agreement.

              6. This Letter Agreement may be executed by the parties hereto in
counterparts, each of which shall be deemed to be an original, but all such
counterparts shall together constitute one and the same instrument.

              7. This Letter Agreement shall constitute a part of the Employment
Agreement.

If this Letter Agreement correctly sets forth our agreement on the subject
matter hereof, please sign and return to M&T the enclosed copy of this letter.

                                        Very truly yours,

ROBERT J. BENNETT                       M&T BANK CORPORATION
