Securities by the Holders (as herein defined) thereof, it is mutually
covenanted and agreed, for the equal and proportionate benefit, subject to
Article 16, of all Holders of the Securities or of any series thereof and any
Coupons (as herein defined) as follows:

reference to another Section hereof, have the meanings assigned to them in this

                  been authenticated and delivered pursuant to this Indenture,

                  reasonably satisfactory to it that such Security is held by a

provided, however, that in determining whether the Holders of the requisite
principal amount of Outstanding Securities have given any request, demand,
authorization, direction, notice, consent or waiver hereunder or are present at
a meeting of Holders of Securities for quorum purposes, (i) the principal
amount of an Original Issue Discount Security that may be counted in making
such determination and that shall be deemed to be Outstanding for such purposes
shall be equal to the amount of the principal thereof that pursuant to the
terms of such Original Issue Discount Security would be declared (or shall have
been declared to be) due and payable upon a declaration of acceleration thereof
pursuant to Section 5.2 at the time of such determination, and (ii) the

the principal amount of a Security denominated in a Foreign Currency shall be
the Dollar equivalent, determined on the date of original issuance of such
Security, of the principal amount (or, in the case of an Original Issue
Discount Security, the Dollar equivalent on the date of original issuance of
such Security of the amount determined as provided in (i) above) of such
Security, and (iv) Securities owned by the Company or any other obligor upon
the Securities or any Affiliate of the Company or such other obligor, shall be
disregarded and deemed not to be Outstanding, except that, in determining
whether the Trustee shall be protected in making any such determination or
relying upon any such request, demand, authorization, direction, notice,

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

                                      13

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
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
or 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,

                                      14
<PAGE>   21

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 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
(a) another certificate or affidavit bearing a later date issued in respect of
the same Bearer Security is produced, (b) such Bearer Security is produced to
the Trustee by some other Person, (c) such Bearer Security is surrendered in
exchange for a Registered Security, or (d) 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.

                                      15
<PAGE>   22

                 (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.

         Section 1.5.      Notices, etc., to Trustee and 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 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 Treasurer at the address of its principal
office specified in the first paragraph of this instrument or at any other
address previously furnished in writing to the Trustee by the Company.

         Section 1.6.      Notice to Holders 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
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 shall be made by overnight courier.

                                      16
<PAGE>   23

         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.

         Section 1.7.      Language of Notices.

         Any request, demand, authorization, direction, notice, consent,
election or waiver required or permitted under this Indenture shall be in the
English language, except that, if the Company so elects, any published notice
may be in an official language of the country of publication.

         Section 1.8.      Conflict with Trust Indenture Act.

         If any provision hereof limits, qualifies or conflicts with any duties
under any required provision of the Trust Indenture Act imposed hereon by
Section 318(c) thereof, such required provision shall control.

         Section 1.9.      Effect of Headings and Table of Contents.

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

         Section 1.10.     Successors and Assigns.

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

         Section 1.11.     Separability Clause.

         In case any provision in this Indenture, any Security or any Coupon
shall be invalid, illegal or unenforceable, the validity, legality and
enforceability of the remaining provisions shall not in any way be affected or
impaired thereby.

         Section 1.12.     Benefits of Indenture.

         Nothing in this Indenture, any Security or any Coupon, express or
implied, shall give to any Person, other than the parties hereto, any Security
Registrar, any Paying Agent and any Authenticating Agent and their respective
successors hereunder and the Holders of Securities or Coupons, any benefit or
any legal or equitable right, remedy or claim under this Indenture.

                                      17

         Section 1.13.     Governing Law.

         This Indenture, the Securities and any Coupons shall be governed by
and construed in accordance with the laws of the State of New York applicable
to agreements made or instruments entered into and, in each case, performed in
said state.

         Section 1.14.     Business Day Convention.

         Unless otherwise specified in or pursuant to this Indenture or any
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
convert or exchange Securities of a series that are convertible or
exchangeable, shall be a day that is not a Business Day at any Place of
Payment, then (notwithstanding any other provision of this Indenture, any
Security or any Coupon other than a provision in any Security or Coupon that

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 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

         Unless otherwise provided in or pursuant to this Indenture or any
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 amount, or any increase or decrease in the amount, or changes in the rights
of 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
thereto. Subject to the provisions of Section 3.3 and, if applicable, Section
3.4, the Trustee shall deliver and redeliver, in each case at the Company's
expense, any Security in permanent global form in the manner and upon
instructions given by the Person or Persons specified therein or in the
applicable Company Order. If a Company Order pursuant to Section 3.3 or 3.4 has
been, or simultaneously is, delivered, any instructions by the Company with
respect to a Security in global form shall be in writing but need not be
accompanied by or contained in an Officers' 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 Securities, 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.

any series may provide, without limitation, that the Securities shall be
authenticated and delivered by the Trustee on original issue from time to time

         Section 3.2.      Currency; Denominations.

         Unless otherwise provided in or pursuant to this Indenture, the
principal of, any premium and interest on and any Additional Amounts with
respect to the Securities shall be payable in Dollars. Unless otherwise
provided in or pursuant to this Indenture, Registered Securities denominated in
Dollars shall be issuable in registered form without Coupons in denominations
of $1,000 and any integral multiple thereof, and the Bearer Securities
denominated in Dollars shall be issuable in the denomination of $5,000.
Securities not denominated in Dollars shall be issuable in

                                      24
<PAGE>   31

such denominations as are established with respect to such Securities in or
pursuant to this Indenture.

         Section 3.3.      Execution, Authentication, Delivery and Dating.

         Securities shall be executed on behalf of the Company by its Chairman
of the Board, one of its Vice Chairmen, its President, its Treasurer or one of
its Vice Presidents under its corporate seal reproduced thereon and attested by
its Secretary or one of its Assistant Secretaries. Coupons shall be executed on
behalf of the Company by the Treasurer or any Assistant Treasurer of the
Company. The signature of any of these officers on the Securities or any
Coupons appertaining thereto may be manual or facsimile.

         Securities and any Coupons appertaining thereto bearing the manual or
facsimile signatures of individuals who were at any time the proper officers of
the Company shall bind the Company, notwithstanding that such individuals or
any of them have ceased to hold such offices prior to the authentication and
delivery of such Securities 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 Officers'
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, or
make available for delivery, 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 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 a proceeding in equity or at

                                      25
<PAGE>   32

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;

                 (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; and

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

            (2) an Officers' Certificate stating that all conditions precedent
to the execution, authentication and delivery of such Securities and Coupons,
if any, appertaining thereto, have been complied with and that, to the best
knowledge of the Persons executing such certificate, 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 Officers'
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
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.

         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 6.11 executed by or on behalf of the
Trustee or by the Authenticating Agent by the manual signature of one of its
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.

         Section 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

                                      26
<PAGE>   33

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.

         Section 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 "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

                                      27
<PAGE>   34

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 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.

                                      28
<PAGE>   35

         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 Officers' 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 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

                                      29
<PAGE>   36

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.

         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 any 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 selection, (ii) to register the transfer of or
exchange any Registered Security so 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, (iii) to exchange any Bearer Security so 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.

         Section 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.

                                      30
<PAGE>   37

         If there be delivered to the Company and to 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; 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.

         Section 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

                                      31
<PAGE>   38

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 in each
case, as provided in Clause (1) or (2) below:

                 (1) The Company may elect to make payment of any Defaulted
Interest to the 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 in this clause provided. 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 shall, 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, 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

                                      32
<PAGE>   39

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.

         In the case of any Registered Security of any series that is
convertible into shares of Common Stock or exchangeable for other securities,
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.

         Section 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.

         Section 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 disposed of by the Trustee in its
customary manner, unless by a Company Order the Company directs their return to
it.

         Section 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.

         Section 3.11.     CUSIP Numbers.

         The Company in issuing Securities may obtain CUSIP numbers (if then
generally in use) or other identifying numbers, and, if so obtained, the
Trustee shall use such numbers in notices of redemption as a convenience to
Holders; provided that any such notice may state that no representation is made
as to the correctness of such numbers either as printed on the Securities or as
contained in any notice of a redemption and that reliance may be placed only on
the other identification numbers printed on the Securities, and any such
redemption shall not be affected by any defect in or omission of such numbers.
The Company will promptly notify the Trustee of any change in the CUSIP or
other identifying numbers.

                    SATISFACTION AND DISCHARGE OF INDENTURE

         Section 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
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,

                               (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 Officers'
Certificate and an Opinion of Counsel, each stating that all conditions
precedent herein provided for relating to the satisfaction and discharge of
this Indenture as to such series have been complied with.

         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 6.6 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

                                      35
<PAGE>   42

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 Common Stock
or other securities shall survive.

         Section 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 clause (3) of this Section 4.2 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 Common Stock or
exchange such Securities for other securities, (ii) the obligations of the
Company and the Trustee with respect to such Securities under Sections 3.5,
3.6, 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 Common Stock or exchange such Securities for other securities, (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.

                 (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, 10.6 and
10.7, 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(9) 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 (or another trustee satisfying the
requirements of Section 6.7 who shall agree to comply with the provisions of
this Section 4.2 applicable to it) as trust funds in trust for the purpose of
making the following payments, specifically pledged as security for, and
dedicated solely to, the 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, 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 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.

<PAGE>   44

                        (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.

                        (g) The Company shall have delivered to the Trustee an
Officers' Certificate and an Opinion of Counsel, each 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) have been complied with.

                        (h) 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.

<PAGE>   45

                        (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 (or other qualifying
trustee, collectively for purposes of this Section 4.2(5) and Section 4.3, 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 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, are in
excess of the amount 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.

         Section 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 (including the Company acting as its own
Paying Agent) 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.

    Section 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 with respect to the Company
specified in clause (7) or (8) 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

                                      41
<PAGE>   48

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 with respect to the Company specified in clause (7)
or (8) of Section 5.1 occurs, all unpaid principal of and accrued interest on
and any Additional Amounts payable in respect of 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

                (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 6.6;
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.

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

    The Company covenants that if

                                      42
<PAGE>   49

        (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 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 6.6.

    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.

    Section 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,

                                      43
<PAGE>   50

        (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 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 6.6.

    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.

    Section 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.

    Section 5.6. Application of Money Collected.

    Subject to Article 16, as it may be modified pursuant to Section 3.1, 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

    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.

    Section 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

                                      45
<PAGE>   52

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.

    Section 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.

    Section 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.

    Section 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.

    Section 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

                                      46
<PAGE>   53

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

    Section 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.

    Section 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.

    Section 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
any undertaking to pay the costs of such suit, and that such court may in its
discretion assess reasonable costs, including reasonable attorneys' fees and
expenses, 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 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

                                      47
<PAGE>   54

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 Common Stock or other securities in accordance with its
terms.

                                   ARTICLE 6

        (12) the Trustee shall not be deemed to have notice of any Default or
Event of Default unless a Responsible Officer of the Trustee has actual

<PAGE>   56

    Section 6.6. Compensation and Reimbursement.

    The Company agrees:

        (1) to pay to the Trustee from time to time such compensation as shall

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

                                      50
<PAGE>   57

compensation and the expenses and disbursements of its agents and counsel),

arising out of or in connection with the acceptance or administration of the
trust or trusts hereunder, including the costs and expenses of defending
themselves against any claim or liability in connection with the exercise or
performance of any of their powers or duties hereunder, except to the extent

this Section, the Trustee shall have a lien prior to the Securities of any
series upon all property and funds held or collected by the Trustee as such,
except funds held in trust for the payment of principal of, and premium or
interest on or any Additional Amounts with respect to Securities or any Coupons
appertaining thereto.

    To the extent permitted by law, any compensation or expense incurred by the
Trustee after a default specified in or pursuant to Section 5.1 is intended to

insolvency law. "Trustee" for purposes of this Section 6.6 shall include any
predecessor Trustee but the negligence or willful misconduct of any Trustee
shall not affect the rights of any other Trustee under this Section 6.6.

    The provisions of this Section 6.6 shall survive the satisfaction and
discharge of this Indenture or the earlier resignation or removal of the

indenture qualified under the Trust Indenture Act and that 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 and that is subject to supervision or
examination by Federal or state authority. If at any time the Trustee shall
cease to be eligible in accordance with the provisions of this Section, it
shall resign immediately in the manner and with the effect hereinafter
specified in this Article.

        (2) The following indentures shall be considered specifically described
herein for purposes of clause (i) of the proviso contained in Section 310(b)(1)
of the Trust Indenture Act: Indenture Relating to Subordinated Debt Securities
dated as of _____, 20___ between the Company and The Bank of New York as
trustee; and pursuant to Section 310(b)(1)(C)(i) of the Trust Indenture Act,
unless otherwise ordered by the Commission, an Event of Default by the Company
under this Indenture will not disqualify the Trustee under this Indenture
because it is a trustee under such other indenture.

    Section 6.8. Resignation and Removal; Appointment of Successor.

        (1) No resignation or removal of the Trustee and no appointment of a
successor Trustee pursuant to this Article shall become effective until the
acceptance of appointment by the successor Trustee pursuant to Section 6.9.

        (2) The Trustee may resign at any time with respect to the Securities
of one or more series by giving written notice thereof to the Company. If the
instrument of acceptance by a successor Trustee required by Section 6.9 shall
not have been delivered to the Trustee within 30 days after the giving of such
notice of resignation, the resigning Trustee may petition any court of
competent jurisdiction, at the expense of the Company, for the appointment of a
successor Trustee with respect to such series.

        (3) The Trustee may be removed at any time with respect to the
Securities of any series by Act of the Holders of a majority in principal
amount of the Outstanding Securities of such series, delivered to the Trustee
and the Company. If the instrument of acceptance by a successor Trustee
required by Section 6.9 shall not have been delivered to the Trustee within 30
days after delivery of such Act of Holders, the Trustee being removed may
petition any court of competent jurisdiction, at the expense of the Company,
for the appointment of a successor Trustee with respect to such series.

        (4) If at any time:

                (a) the Trustee shall fail to comply with the obligations
imposed upon it under Section 310(b) of the Trust Indenture Act with respect to
Securities of any series after written request therefor by the Company or any
Holder of a Security of such series who has been a bona fide Holder of a
Security of such series for at least six months, or

                (b) the Trustee shall cease to be eligible under Section 6.7
and shall fail to resign after written request therefor by the Company or any
such Holder, or

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

then, in any such case, (i) the Company, by or pursuant to a Board Resolution,
may remove the Trustee with respect to all Securities or the Securities of such
series, or (ii) subject to Section 315(e) of the Trust Indenture Act, any
Holder of a Security who has been a bona fide Holder of a Security of such
series for at least six months may, on behalf of himself and all others
similarly situated, petition any court of competent jurisdiction for the
removal of the Trustee with respect to all Securities of such series and the
appointment of a successor Trustee or Trustees.

        (5) If the Trustee shall resign, be removed or become incapable of
acting, or if a vacancy shall occur in the office of Trustee for any cause,
with respect to the Securities of one or more series, the Company, by or
pursuant to a Board Resolution, shall promptly appoint a successor Trustee or
Trustees with respect to the Securities of such series (it being understood
that any such successor Trustee may be appointed with respect to the Securities
of one or more or all of

                                      52
<PAGE>   59

such series and that at any time there shall be only one Trustee with respect
to the Securities of any particular series) and shall comply with the
applicable requirements of Section 6.9. If, within one year after such
resignation, removal or incapacity, or the occurrence of such vacancy, a
successor Trustee with respect to the Securities of any series shall be
appointed by Act of the Holders of a majority in principal amount of the
Outstanding Securities of such series delivered to the Company and the retiring
Trustee, the successor Trustee so appointed shall, forthwith upon its
acceptance of such appointment in accordance with the applicable requirements
of Section 6.9, become the successor Trustee with respect to the Securities of
such series and to that extent supersede the successor Trustee appointed by the
Company. If no successor Trustee with respect to the Securities of any series
shall have been so appointed by the Company or the Holders of Securities and
accepted appointment in the manner required by Section 6.9, any Holder of a
Security who has been a bona fide Holder of a Security of such series for at
least six months may, on behalf of himself and all others similarly situated,
petition any court of competent jurisdiction for the appointment of a successor
Trustee with respect to the Securities of such series.

        (6) The Company shall give notice of each resignation and each removal
of the Trustee with respect to the Securities of any series and each
appointment of a successor Trustee with respect to the Securities of any series
by mailing written notice of such event by first-class mail, postage prepaid,
to the Holders of Registered Securities, if any, of such series as their names
and addresses appear in the Security Register and, if Securities of such series
are issued as Bearer Securities, by publishing notice of such event once in an
Authorized Newspaper in each Place of Payment located outside the United
States. Each notice shall include the name of the successor Trustee with
respect to the Securities of such series and the address of its Corporate Trust
Office.

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

    Section 6.9. 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
accepting such appointment, and thereupon the resignation or removal of the
retiring Trustee shall become effective and such successor Trustee, without any
further act, deed or conveyance, shall become vested with all the rights,
powers, trusts and duties hereunder of the retiring Trustee; but, on the
request of the Company or such successor Trustee, such retiring Trustee, upon
payment of its charges, shall execute and deliver an instrument transferring to
such successor Trustee all the rights, powers and trusts of the retiring
Trustee and, subject to Section 10.3, shall duly assign, transfer and deliver
to such successor Trustee all property and money held by such retiring Trustee
hereunder, subject nevertheless to its claim, if any, provided for in Section
6.6.

        (2) Upon the appointment hereunder of any successor Trustee with
respect to the Securities of one or more (but not all) series, the Company, the
retiring Trustee and such successor Trustee shall execute and deliver an
indenture supplemental hereto wherein each successor Trustee shall accept such
appointment and which (1) shall contain such provisions as shall be necessary
or desirable to transfer and confirm to, and to vest in, 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

                                      53
<PAGE>   60

which the appointment of such successor Trustee relates, (2) if the retiring
Trustee is not retiring with respect to all Securities, shall contain such
provisions as shall be deemed necessary or desirable to confirm that all the
rights, powers, trusts and duties of the retiring Trustee with respect to the
Securities of that or those series as to which the retiring Trustee is not
retiring shall continue to be vested in the retiring Trustee, and (3) shall add
to or change any of the provisions of this Indenture as shall be necessary to
provide for or facilitate the administration of the trusts hereunder by more
than one Trustee, it being understood that nothing herein or in such
supplemental indenture shall constitute such Trustees co-trustees of the same
trust, 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 payment of its charges
with respect to the Securities of that or those series to which the appointment
of such successor Trustee relates and subject to Section 10.3 shall duly
assign, transfer and deliver to such successor Trustee, to the extent
contemplated by such supplemental indenture, the property and money held by
such retiring Trustee hereunder with respect to the Securities of that or those
series to which the appointment of such successor Trustee relates, subject to
its claim, if any, provided for in Section 6.6.

        (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.

    Section 6.11. Appointment of Authenticating Agent.

    The Trustee may appoint one or more Authenticating Agents 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 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 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 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 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.

                                      55
<PAGE>   62

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

    The provisions of Sections 3.8, 6.3 and 6.4 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.

                                   By                                    ,
                                     ------------------------------------
                                                Authorized Officer

    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 Officers' 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.

                                   COVENANTS

appertaining thereto and this Indenture. Any interest due on any Bearer

surrender of the Coupons appertaining thereto for such interest as they
severally mature.

    Section 10.2. Maintenance of Office or Agency.

    The Company shall maintain in each Place of Payment for any series of

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 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

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 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.

    Section 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

                                      64
<PAGE>   71

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 written 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 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 trust
money, and all liability of the Company as trustee thereof, shall thereupon
cease; provided, however, that the Trustee or such Paying Agent, before being
required to make any such repayment, shall, at the request and expense of the
Company, cause to be published once, in an

                                      65
<PAGE>   72

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.

    Section 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 the payment of 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 Officers' Certificate, the Company
shall furnish to the Trustee and the principal Paying Agent or Paying Agents,
if other than the Trustee, an Officers' 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 Officers'
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
fully indemnify the Trustee and any Paying Agent for, and to hold them harmless
against, any loss, liability or expense reasonably incurred without negligence,
bad faith or willful misconduct on their part arising out of or in connection
with actions taken or omitted by any of them in reliance on any Officers'
Certificate furnished pursuant to this Section.

    Section 10.5. Limitations upon Liens.

                (a) The Company will not, and will not permit any Restricted
Subsidiary to, create, incur, issue, assume or guarantee any Indebtedness
secured by any Lien on any property

                                      66
<PAGE>   73

(including shares of Capital Stock or Indebtedness) or assets of the Company or
any Restricted Subsidiary, whether now owned or hereafter acquired, without in
any such case effectively providing concurrently with the creation, incurrence,
issuance, assumption or guarantee of such Indebtedness or the grant of any Lien
with respect to such Indebtedness that all Securities Outstanding at such time
(together with, if the Company so determines, any other Indebtedness of the
Company or such Restricted Subsidiary then existing or thereafter created which
is not subordinate to the Securities Outstanding at such time) will be secured
by any such Lien equally and ratably with (or prior to) such secured
Indebtedness, so long as such secured Indebtedness is so secured; provided,
however, that no such Lien shall be granted with respect to any Indebtedness
under this Section 10.5(a) so long as prohibited by the Credit Facility or
otherwise. The foregoing restriction and proviso will not, however, apply to
Indebtedness secured by:

         (i)      Liens on property or assets of the Company or any Restricted
                  Subsidiary existing on the date of the original issuance of
                  the applicable series of Securities or such other date as may
                  be specified for an applicable series of Securities,

         (ii)     Liens on shares of Capital Stock of any Subsidiary of the
                  Company securing Indebtedness of the Company under the Credit
                  Facility, whether now existing or hereafter arising,

         (iii)    Liens on property or assets of any Person existing at the
                  time such Person becomes a Restricted Subsidiary or is merged
                  with or into or consolidated with the Company or a Restricted
                  Subsidiary, or at the time of a sale, lease or other
                  disposition of the properties of a Person as an entirety or
                  substantially as an entirety to the Company or a Restricted
                  Subsidiary, or arising thereafter pursuant to contractual
                  commitments entered into prior to and not in contemplation of
                  such Person becoming a Restricted Subsidiary and not in
                  contemplation of any such merger or consolidation or any such
                  sale, lease or other disposition; provided that such Liens
                  shall not extend to any other property or assets of the
                  Company or any Restricted Subsidiary,

         (iv)     Liens on property or assets of the Company or any Restricted
                  Subsidiary existing at the time of acquisition thereof
                  (including acquisition through merger or consolidation);
                  provided that such Liens were in existence prior to and were
                  not created in contemplation of such acquisition and shall
                  not extend to any other property or assets of the Company or
                  any Restricted Subsidiary,

         (v)      Liens on property (including in the case of a plant or
                  facility, the land on which it is erected and fixtures
                  comprising a part thereof) or assets of the Company or any
                  Restricted Subsidiary securing the payment of all or any part
                  of the purchase price or construction cost thereof or
                  securing any Indebtedness created, incurred, assumed or
                  guaranteed prior to, at the time of or within 180 days after,
                  the acquisition of such property or assets or the completion
                  of any such construction, whichever is later, for the purpose
                  of financing all or any part of the purchase price or
                  construction cost thereof (provided, in the case of Liens
                  securing the payment of all or any part of the purchase price
                  of any property or assets of the Company or any Restricted
                  Subsidiary, as the case may be, or securing any Indebtedness

                  financing all or any part of such purchase price, such Liens
                  are limited to the property or assets then being acquired and
                  fixed improvements thereon and the Capital Stock of any
                  person formed to acquire such property or assets, and,
                  provided further, that in the case of Liens securing the
                  payment of all or any part of the construction cost of any
                  property of the Company or any Restricted Subsidiary, as the
                  case may be, or securing any Indebtedness created, incurred,
                  assumed or guaranteed for the purpose of financing all or any
                  part of such construction cost, such Liens are limited to the
                  assets or property then being constructed and the land on
                  which such property is erected and fixtures comprising a part
                  thereof),

                  cost of development, operation, construction, alteration,
                  repair or improvement of all or any part of such property or
                  assets, or to secure Indebtedness incurred prior to, at the
                  time of or within 180 days after, the completion of such
                  development, operation, construction, alteration, repair or
                  improvement, whichever is later, for the purpose of financing
                  all or any part of such cost (provided such Liens do not
                  extend to or cover any property or assets of the Company or
                  any Restricted Subsidiary other than the property or assets
                  then being developed, constructed, altered, repaired or
                  improved and the land on which such property is erected and
                  fixtures comprising a part thereof),

                  collected by the applicable trustee in its capacity as
                  trustee,

         (xiv)    Liens that are within the general parameters customary in the
                  industry and incurred in the ordinary course of business
                  securing Indebtedness under any Interest Rate Agreement or
                  Currency Agreement designed solely to protect the Company or
                  any of its Restricted Subsidiaries from fluctuations in
                  interest rates, currencies or the price of commodities,

         (xv)     Liens incurred (a) in connection with workers' compensation,

                  to secure the performance of Surety Obligations incurred in
                  the ordinary course of business consistent with industry
                  practice, or (c) to obtain or secure obligations with respect

                  in clauses (a) and (b) above, in each case not incurred or
                  made in connection with the borrowing of money, the obtaining
                  of advances or credit or the payment of the deferred purchase
                  price of property or services, or (d) Liens securing
                  performance of leases, construction, sales or servicing
                  contracts and similar obligations incurred in the ordinary
                  course of business, in each case not incurred or made in
                  connection with the borrowing of money,

         (xvi)    judgment Liens against the Company or any Restricted
                  Subsidiary not giving rise to an Event of Default, and

         (xvii)   any extension, renewal, substitution or replacement (or
                  successive extensions, renewals, substitutions or
                  replacements), in whole or in part, of any of the Liens
                  referred to in paragraphs (i) through (xvi) above or the
                  Indebtedness secured thereby.

         Notwithstanding the foregoing, the Company and any Restricted
Subsidiary may create, incur, issue or assume Indebtedness secured by a Lien
which would otherwise be subject to the foregoing restrictions if the aggregate
principal amount of all Indebtedness secured by Liens on property or assets of
the Company and of any Restricted Subsidiary then outstanding (not including
any such Indebtedness secured by Liens permitted to be incurred pursuant to
paragraphs (i) through (xvii) above) plus Attributable Debt of the Company and
its Restricted Subsidiaries in respect of Sale and Leaseback Transactions that
would otherwise be subject to the restrictions in

                                      69
<PAGE>   76
Section 10.6 does not at the time such Indebtedness is incurred exceed an amount
equal to 10% of Consolidated Net Tangible Assets.

                  (b) For the purposes of clause (a) above, the giving of a
guarantee which is secured by a Lien and the creation of a Lien to secure
Indebtedness which existed prior to the creation of such Lien, will be deemed to
involve the creation of Indebtedness in an amount equal to the principal amount
guaranteed or secured by such Lien; but the amount of Indebtedness secured by
Liens will be computed without cumulating the underlying Indebtedness with any
guarantee thereof or Lien securing the same.

                  (c) For the purposes of determining compliance with this
Section 10.5, in the event that an item of Indebtedness meets the criteria of
more than one of the types of Indebtedness described in clause (a) above, the
Company, in its sole discretion, will classify, and may reclassify, such
Indebtedness and only be required to include the amount and type of such
Indebtedness in one of the items of clause (a) above may be divided and
classified and reclassified into more than one of the types of Indebtedness
described above.

                  (d) The provisions of this Section 10.5 shall be subject
to the provisions of Article 16, as they may be modified pursuant to Section
3.1, in the case of any series of Securities secured pursuant to Article 16,
such that the provisions of this Section 10.5, including the 10% exception
referred to in Section 105(a), shall not apply to limit the right of Holders of
Securities secured pursuant to Article 16 to be secured equally and ratably with
the Lenders under the Credit Facility with regard to any Collateral from time to
time pledged pursuant to the Credit Facility.

         Section 10.6. Limitations upon Sales and Leasebacks.

         The Company will not, and will not permit any Restricted Subsidiary to,
enter into any arrangement after the date of the original issuance of the
applicable series of Securities or such other date as may be specified for an
applicable series of Securities with any bank, insurance company or other lender
or investor (other than the Company or another Restricted Subsidiary) providing
for the leasing by the Company or any such Restricted Subsidiary of any property
or assets for a period of more than three years, which was or is owned or leased
by the Company or a Restricted Subsidiary and which has been or is to be sold or
transferred by the Company or such Restricted Subsidiary to such lender or
investor or to any Person to whom funds have been or are to be advanced by such

to as a "Sale and Leaseback Transaction") unless either:

         (i)      the Company and its Restricted Subsidiaries would be entitled,
                  pursuant to Section 10.5, to incur Indebtedness secured by a
                  Lien on such property or assets in a principal amount equal to
                  or exceeding the Attributable Debt in respect of such Sale and
                  Leaseback Transaction without equally and ratably securing the
                  applicable series of Securities; or

         (ii)     the Company, within 180 days after the sale or transfer,
                  applies or causes a Restricted Subsidiary to apply an amount
                  equal to the greater of the net proceeds of such sale or
                  transfer or the fair value of the property or assets subject

                  and the Controller of the Company) to the retirement of
                  Securities or other Funded Debts of the Company (other than
                  Funded Debt subordinated to the Securities) or Funded Debt of
                  a Restricted Subsidiary; provided that the amount to be so
                  applied shall be reduced by (a) the principal amount of
                  Securities delivered within 180 days after such sale or
                  transfer to the Trustee for retirement and cancellation, and
                  (b) the principal amount of any such Funded Debt of the
                  Company or a Restricted Subsidiary, other than Securities,
                  voluntarily retired by the Company or a Restricted Subsidiary
                  within 180 days after such sale or transfer to the Trustee for
                  retirement and cancellation, excluding in the case of both (a)
                  and (b), retirement pursuant to any mandatory sinking fund
                  payment or any mandatory prepayment provision or by payment at
                  maturity.

         Section 10.7. Restrictions on Funded Debt of Restricted Subsidiaries.

         The Company will not permit any Restricted Subsidiary to create, incur,
issue, assume or guarantee any Funded Debt. This restriction will not apply if:

         (i)      The Company or such Restricted Subsidiary could create
                  Indebtedness secured by Liens in accordance with one or more
                  of clauses (i) through (xvii) of Section 10.5 (a) (whether or
                  not such Indebtedness is in fact secured by Liens) or enter
                  into a Sale and Leaseback Transaction in accordance with
                  Section 10.6 in an amount equal to such Funded Debt, without
                  equally and ratably securing the Securities,

         (ii)     such Funded Debt existed on the date of the original issuance
                  of the applicable series of Securities or such other date as
                  may be specified for an applicable series of Securities,

         (iii)    such Funded Debt is owed to the Company or any Restricted
                  Subsidiary,

         (iv)     such Funded Debt existed at the time the Person that issued
                  such Funded Debt became a Restricted Subsidiary, or was merged
                  with or into or consolidated with such Restricted Subsidiary,
                  or at the time of a sale, lease or other disposition or the
                  properties of such Person as an entirety to such Restricted
                  Subsidiary, or arising thereafter

                  (a)      otherwise than in connection with the borrowing of
                           money arranged thereafter and

                  (b)      pursuant to contractual commitments entered into
                           prior to and not in contemplation of such Person
                           becoming a Restricted Subsidiary and not in
                           contemplation of any such merger or consolidation or
                           any such sale, lease or other disposition,

         (v)      such Funded Debt is guaranteed by the Company,

         (vi)     such Funded Debt is guaranteed by a governmental agency,

                                       71
<PAGE>   78

         (vii)    such Funded Debt is issued, assumed or guaranteed in
                  connection with, or with a view to, compliance by such
                  Restricted Subsidiary with the requirements of any program
                  adopted by any federal, state or local governmental authority
                  and applicable to such Restricted Subsidiary and providing
                  financial or tax benefits to such Restricted Subsidiary which
                  are not available directly to the Company,

         (viii)   such Funded Debt is issued, assumed or guaranteed to pay all
                  or any part of the purchase price or the construction cost of
                  property or equipment acquired or constructed by a Restricted
                  Subsidiary, provided such Funded Debt is incurred within 180
                  days after acquisition, completion of construction or
                  commencement of full operation of such property, whichever is
                  later, and, provided further, that the principal amount of
                  such Funded Debt does not exceed 100% of the fair market value
                  of the property or equipment acquired or constructed,

         (ix)     such Funded Debt is nonrecourse, or

         (x)      such Funded Debt is incurred for the purpose of extending,
                  renewing, substituting, replacing or refunding Funded Debt
                  permitted by the foregoing clauses (i) through (ix).

         Notwithstanding the foregoing, any Restricted Subsidiary may create,
incur, issue, assume or guarantee Funded Debt which would otherwise be subject
to the foregoing restrictions in an aggregate principal amount which, together
with the aggregate outstanding principal amount of all other Funded Debt of the
Company's Restricted Subsidiaries which would otherwise be subject to the
foregoing restrictions (not including Funded Debt permitted to be incurred
pursuant to clauses (i) through (x) above), does not at the time such Funded
Debt is incurred exceed an amount equal to 10% of Consolidated Net Tangible
Assets.

         Section 10.8. Corporate Existence.

         Subject to Article Eight, the Company shall do or cause to be done all
things necessary to preserve and keep in full force and effect its corporate
existence and the existence of each of its Restricted Subsidiaries and the
rights (charter and statutory) and franchises of the Company and each of its
Restricted Subsidiaries; provided, however, that the foregoing shall not
obligate the Company to preserve the existence of any of its Restricted
Subsidiaries or any such right or franchise if the Board of Directors of the
Company shall determine that the preservation thereof is no longer desirable in
the conduct of the business of the Company and its Subsidiaries, taken as a
whole, and that the loss thereof is not disadvantageous in any material respect
to any Holder.

         Section 10.9. Waiver of Certain Covenants.

         The Company may omit in any particular instance to comply with any
term, provision or condition set forth in Sections 10.5 through 10.8, inclusive,
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

                                       72
<PAGE>   79

the Company and the duties of the Trustee in respect of any such term, provision
or condition shall remain in full force and effect.

         Section 10.10. Company Statement as to Compliance; Notice of Certain
         Defaults.

                  (1) The Company shall deliver to the Trustee, within 120 days
after the end of each fiscal year, a written statement (which need not be
contained in or accompanied by an Officers' Certificate) signed by the principal
executive officer, the principal financial officer or the principal accounting
officer of the Company, stating that

                           (a) a review of the activities of the Company during
such year and of its performance under this Indenture has been made under his or
her supervision, and

                           (b) to the best of his or her knowledge, based on
such review, (a) the Company has complied with all the conditions and covenants
imposed on it under this Indenture throughout such year, or, if there has been a
default in the fulfillment of any such condition or covenant, specifying each
such default known to him or her and the nature and status thereof, and (b) no
event has 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.

         Section 10.11. Calculation of Original Issue Discount.

         The Company shall file with the Trustee promptly at the end of each
calendar year (i) a written notice specifying the amount of original issue
discount (including daily rates and accrual periods) accrued on Outstanding
Securities as of the end of such year and (ii) such other specific information
relating to such original issue discount as may then be relevant under the
Internal Revenue Code of 1986, as amended from time to time.

                                   ARTICLE 11

                            REDEMPTION OF SECURITIES

         Section 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.

         Section 11.2. Election to Redeem; Notice to Trustee.

         The election of the Company to redeem any Securities shall be evidenced
by or pursuant to a Board Resolution. In case of any redemption at the election
of the Company 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,

                                       73
<PAGE>   80

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 in
writing of such Redemption Date and of the principal amount of Securities of
such series to be redeemed.

         Section 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 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 Common Stock or exchanged for other securities 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.

         Section 11.4. Notice of Redemption.

         Notice of redemption shall be given 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:

                                       74
<PAGE>   81

                  (1) the Redemption Date,

                  (2) the Redemption Price,

                  (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 Clearstream
reference numbers of such Securities, if any (or any other numbers used by a
Depository to identify such Securities).

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

                                       75
<PAGE>   82

         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.

         Section 11.5. Deposit of Redemption Price.

         On or prior to 10:00 a.m., New York City time, on 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.

         Section 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 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

                                       76
<PAGE>   83

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.

         Section 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.

                                   ARTICLE 12

                                  SINKING FUNDS

         Section 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 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.

         Section 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

                                       77
<PAGE>   84

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 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.

         Section 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 Officers'
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 Officers' 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 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, the

the contrary in the form of Security of any particular series or pursuant to

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

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

         Section 16.1. Applicability of Article.

         The securing of payments due on Securities of any series, if so

         The security interest or interests granted pursuant to this Article in
any Collateral shall continue for so long as, but only for so long as, the
security interest or interests granted in such Collateral in connection with the
Credit Facility are not terminated or otherwise released by the Lenders that are
parties to the Credit Facility and shall terminate in any event when the Credit
Facility expires; provided, that the security interest or interest granted
pursuant to this Article shall continue in effect in the event of any amendment,
extension, renewal, substitution or replacement, or successive amendment,
extension, renewal, substitution or replacement, of the Credit Facility or any
obligations owing under the Credit Facility.

Amounts payable with respect thereto, and performance of all other obligations
of the Company to the Holders or the Trustee under this Indenture and the
Securities of each applicable series, according to the terms hereof or thereof,
the Company shall, prior to or simultaneously with the initial issuance of
Securities secured in accordance with this Article 16, enter into the Collateral
Documents and make an assignment and pledge of its rights, title and interests
in and to the Collateral to the Collateral Agent pursuant to the Collateral
Documents and to the extent therein provided. The Company covenants and agrees,
for the benefit of Securities secured pursuant to this Article, to duly perform
all of its obligations under the Collateral Documents. Each Holder of a Security
of an applicable series, by its acceptance thereof, consents and agrees to the
terms of the Collateral Documents (including, without limitation, the provisions
providing for the release of Collateral) as the same may be in effect or may be
amended from time to time in accordance with their terms, and authorizes and
directs the Collateral Agent to enter into each of the Collateral Documents to
which it is a party and to perform its obligations and exercise its rights
thereunder in accordance therewith; provided, however, that if any provision of
the Collateral Documents limits, qualifies or conflicts with the duties imposed
by the provisions of the Trust Indenture Act, the Trust Indenture Act shall
control. The Company shall execute, acknowledge and deliver to the Trustee and
the Collateral Agent such further assignments, transfers, assurances or other
instruments as the Trustee or the Collateral Agent may require or request, and
will do or cause to be done all such acts and things as may be necessary or
proper, or as may be required by the Trustee or the Collateral Agent to assure
and confirm to the Trustee and the Collateral Agent the equal and ratable
security interest in the Collateral contemplated hereby and, by the Collateral
Documents or any part thereof, as from time to time constituted, so as to render
the same available for the equal and ratable security and benefit of this
Indenture and of the Securities of each applicable series secured pursuant to
this Article together with each of the other Lenders, according to the intent
and purposes herein expressed. The Collateral Documents will create a valid,
perfected lien on and security interest in the Collateral for the equal and
ratable benefit of Holders of Securities of each applicable series and of each
of the Lenders as set forth therein.

         Notwithstanding any provision to the contrary in this Indenture,
including Section 10.5, on or after the date Securities of any applicable series
are secured as provided above, the Company shall not, and shall not permit any
Restricted Subsidiary to, grant any Lien with respect to obligations owing under
the Credit Facility on any property (including shares of Capital Stock or
Indebtedness) or assets of the Company or any Restricted Subsidiary, whether now
owned or hereafter acquired, without in any such case effectively providing
concurrently with the grant of any such Lien that all Securities of each
applicable series Outstanding at such time will be secured by any such Lien
equally and ratably with any obligation owing under the Credit Facility, by
immediately creating a perfected security interest in favor of the Collateral
Agent in such Collateral pursuant to the Collateral Documents for the equal and
ratable benefit of the Securities of each applicable series secured pursuant to
this Article 16 and, to the extent reasonably determined necessary or desirable
by the Trustee or the Collateral Agent, additional security documents shall be
entered into in order to effectively grant such perfected security interests,
together with such other documents, certificates, resolutions, instruments,
financing statements, opinions and writings that would have been required to be
delivered if such perfected security interests had been created on the date of
this Indenture, all of which shall be in form and substance satisfactory to the
Trustee and the Collateral Agent.

the creation of a security interest for the benefit of the Holders of Securities
of each applicable series an Opinion of Counsel either (i) stating that in the
opinion of such counsel all action has been taken with respect to the delivery
of the Collateral to the Collateral Agent and the execution, registration and/or
filing of any other instruments necessary to make effective the Liens intended
to be created by this Article of the Indenture and the Collateral Documents, and
reciting the details of such action or (ii) stating that, in the opinion of such
counsel, no such action is necessary to make such Liens effective.

                  (b) So long as any Securities of any series are secured
pursuant to this Article 16, the Company shall furnish in respect of each such
series to the Collateral Agent and the Trustee at least once each year, as close
as possible to the anniversary of the applicable opinion delivered pursuant to
Section 16.3(a), an Opinion of Counsel, dated as of such date, either (i)(1)
stating that, in the opinion of such counsel, action has been taken with respect
to the recording, registering, filing, re-recording, re-registering and refiling
of all supplemental indentures, financing statements, continuation statements or
other instruments of further assurance as is necessary to maintain the Lien of
the Collateral Documents and reciting with respect to the security interests in
the collateral the details of such action or referring to prior Opinions of
Counsel in which such details are given and (2) stating that all financing
statements and continuation statements have been executed and filed that are
necessary as of such date and during the succeeding six months fully to preserve
and protect the rights of the Holders of Securities of the applicable series and
the Collateral Agent and the Trustee hereunder and under the Collateral
Documents with respect to the security interests in the Collateral, or (ii)
stating that, in the opinion of such counsel, no such action is necessary to
maintain such Lien and assignment.

         Section 16.4. Release of Collateral.

         Collateral may be released from the lien and security interest created
by the Collateral Documents at any time or from time to time at the sole cost
and expense of the Company and in accordance with the terms hereof and of the
Collateral Documents. Without limiting the generality of the foregoing, it is
specifically acknowledged that the Collateral shall be released from the lien in
favor of the Holders of Securities of the applicable series concurrently with
being released from the lien in favor of all Lenders having an interest in the
Collateral under the Collateral Documents. The Trustee shall execute, deliver or
acknowledge any necessary or proper instruments of termination, satisfaction or
release provided by or on behalf of the Company to evidence the release of any
Collateral permitted to be released pursuant to this Indenture or the Collateral
Documents.

         The release of any Collateral from the terms hereof and of the
Collateral Documents shall not be deemed to impair the security under this
Indenture in contravention of the provisions hereof if and to the extent the
Collateral is released pursuant to the terms hereof and of the Collateral
Documents. The Trustee and each of the Holders of Securities of each applicable
series acknowledge that a release of Collateral in accordance with the terms of
the Collateral Documents shall not be deemed for any purpose to be an impairment
of the security under this Indenture.
