         SECTION 104. ACTS OF HOLDERS.

         (a) Any request, demand, authorization, direction, notice,

by Holders of the Outstanding Securities of all series or one or more series, as
the case may be, may be embodied in and evidenced by one or more instruments of
substantially similar tenor signed by such Holders in person or by agents duly
appointed in writing. If Securities of a series are issuable as Bearer
Securities, any request, demand, authorization, direction, notice, consent,
waiver or other action provided by this Indenture to be given or taken by
Holders 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 Fifteen, 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 TIA Section 315) conclusive in
favor of the Trustee and the Company, if made in the manner provided in this
Section. The record of any meeting of Holders of Securities shall be proved in

                                       13
<PAGE>   19

         (b) The fact and date of the execution by any Person of any such
instrument or writing may be proved in any reasonable manner which the Trustee
deems sufficient.

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

         (d) The principal amount and serial numbers of Bearer Securities
held by any Person, and the date 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, wherever
situated, if such certificate shall be deemed by 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 (1) another certificate or affidavit bearing
a later date issued in respect of the same Bearer Security is produced, or (2)
such Bearer Security is produced to the Trustee by some other Person, or (3)
such Bearer Security is surrendered in exchange for a Registered Security, or
(4) such Bearer Security is no longer Outstanding. The principal amount and
serial numbers of Bearer Securities held by any Person, and the date of holding
the same, may also be proved in any other manner that the Trustee deems
sufficient.

         (e) If the Company shall solicit from the Holders of Registered
Securities any request, demand, authorization, direction, notice, consent,
waiver or other Act, the Company may, at its option, by or pursuant to a Board
Resolution, fix in advance a record date for the determination of such Holders
entitled to give such request, demand, authorization, direction, notice,
consent, waiver or other Act, but the Company shall have no obligation to do so.
Notwithstanding TIA Section 316(c), any such record date shall be the record
date specified in or pursuant to such Board Resolution, which shall be a date
not more than 30 days prior to the first solicitation of Holders generally in
connection therewith and no later than the date such solicitation is completed.
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 record at the close of business on such record
date shall be deemed to be Holders for the purposes of determining whether
Holders of the requisite proportion of Securities then Outstanding have
authorized or agreed or consented to such request, demand, authorization,
direction, notice, consent, waiver or other Act, and for that purpose the
Securities then Outstanding shall be computed as of such record date, provided
that no such request, demand, authorization, direction, notice, consent, waiver
or other Act by the Holders on such record date 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.

         (f) 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 or 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, suffered or omitted to be done by the Trustee, any
Paying Agent or the Company in reliance thereon, whether or not notation of such
action is made upon such Security.

         SECTION 105. NOTICES, ETC., TO TRUSTEE AND COMPANY.

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

         (1) the Trustee by any Holder or the Company shall be sufficient for
every purpose hereunder if made, given, furnished or delivered, in writing, to
or with the Trustee at its Corporate Trust Office, Attention: Corporate Trust
Administration; or

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

         SECTION 106. NOTICE TO HOLDERS; WAIVER.

         Where this Indenture provides for notice of any event to Holders of
Registered Securities by the Company or the Trustee, such notice shall be
sufficiently given (unless otherwise herein expressly provided) if in writing
and mailed, first-class postage prepaid, to each Holder affected by such event,
at 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. 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 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. Any notice mailed to a
Holder in the aforesaid manner shall be conclusively deemed to have been
received by such Holder, whether or not such Holder actually receives such
notice.

         In case, by reason of the suspension of or irregularities in regular
mail service or by reason of any other cause, it shall be impractical to mail
notice of any event to Holders of Registered Securities when such notice is
required to be given pursuant to any provision of this Indenture, then any
manner of giving such notice as shall be satisfactory to the Trustee shall be
deemed to be sufficient giving of such notice for every purpose hereunder.

         Except as otherwise expressly provided herein or otherwise specified
with respect to any Securities pursuant to Section 301, where this Indenture
provides for notice to Holders of Bearer Securities of any event, such notice
shall be sufficiently given to Holders of Bearer Securities if published in an
Authorized Newspaper in The City of New York and in such other city or cities as
may be specified in such Securities on a Business Day at least twice, the first
such publication to be not earlier than the earliest date, and not later than
the latest date, prescribed for the giving of such notice. Any such notice shall
be deemed to have been given on the date of the first such publication.

                                       15
<PAGE>   21

         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 the 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 such notice with
respect to other Holders of Bearer Securities or the sufficiency of any notice
to Holders of Registered Securities given as provided herein.

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

         Where this Indenture provides for notice in any manner, such notice may
be waived in writing by the Person entitled to receive such notice, either
before or after the event, and such waiver shall be the equivalent of such
notice. Waivers of notice by Holders shall be filed with the Trustee, but such
filing shall not be a condition precedent to the validity of any action taken in
reliance upon such waiver.

         SECTION 107. CONFLICT OF ANY PROVISION OF INDENTURE WITH TRUST
INDENTURE ACT.

         If and to the extent that any provision of this Indenture limits,
qualifies or conflicts with the duties imposed by TIA Sections 310 to 318,
inclusive, or conflicts with any provision (an "incorporated provision")
required by or deemed to be included in this Indenture by operation of such TIA
Sections, such imposed duties or incorporated provision shall control. If any
provision of this Indenture modifies or excludes any provision of the Trust
Indenture Act that may be so modified or excluded, the latter provision shall be
deemed to apply to this Indenture as so modified or excluded, as the case may
be.

         SECTION 108. 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 109. SUCCESSORS AND ASSIGNS.

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

<PAGE>   22

         SECTION 110. SEPARABILITY CLAUSE.

         In case any provision in this Indenture or in any Security or 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 111. BENEFITS OF INDENTURE.

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

         SECTION 112. GOVERNING LAW.

         THIS INDENTURE AND THE SECURITIES AND COUPONS SHALL BE GOVERNED BY AND
CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK. THIS INDENTURE
SHALL BE SUBJECT TO, AND GOVERNED BY, THE PROVISIONS OF THE TRUST INDENTURE ACT
OF 1939, AS AMENDED, THAT ARE REQUIRED TO BE PART OF AND TO GOVERN INDENTURES
QUALIFIED THEREUNDER.

         SECTION 113. LEGAL HOLIDAYS.

         In any case where any Interest Payment Date, Redemption Date, sinking
fund payment date or Stated Maturity or Maturity of any Security shall not be a
Business Day at any Place of Payment, then (notwithstanding any other provision
of this Indenture or of any Security or coupon other than a provision in the
Securities of any series which specifically states that such provision shall
apply in lieu of this Section), payment of principal (or premium, if any) or
interest, if any, need not be made at such Place of Payment on such date, but
may be made on the next succeeding Business Day at such Place of Payment with
the same force and effect as if made on the Interest Payment Date or Redemption
Date or sinking fund payment date, or at the Stated Maturity or Maturity;
provided that no interest shall accrue for the period from and after such
Interest Payment Date, Redemption Date, sinking fund payment date, Stated
Maturity or Maturity, as the case may be.

         SECTION 114. NO PERSONAL LIABILITY OF DIRECTORS, OFFICERS, EMPLOYEES,
STOCKHOLDERS OR INCORPORATES.

         No director, officer, employee, incorporator or stockholders, as such,
of the Company shall have any liability for any obligations of the Company under
the Securities or this Indenture or for any claim based on, in respect of, or by
reason of, such obligations or their creations. Each Holder by accepting any of
the Securities waives and releases all such liability. Such waiver and release
are part of the consideration for the issuance of the Securities of any series.

                                 SECURITY FORMS

         SECTION 201. FORMS GENERALLY.

         The Registered Securities, if any, of each series and the Bearer
Securities, if any, of each series and related coupons shall be in substantially
the forms as shall be established by or pursuant to a Board Resolution or in one
or more indentures supplemental hereto, in each case with such appropriate
insertions, omissions, substitutions and other variations as are required or
permitted by this Indenture, and may have such letters, numbers or other marks
of identification and such legends or endorsements placed thereon as may be
required to comply with the rules of any securities exchange or as may,
consistently herewith, be determined by the officers executing such Securities
or coupons, as evidenced by their execution of the Securities or coupons. If the
forms of Securities or coupons of any series are established by action taken
pursuant to a Board Resolution, a copy of an appropriate record of such action
shall be certified by the Secretary or an Assistant Secretary of the Company and
delivered to the Trustee at or prior to the delivery of the Company Order
contemplated by Section 303 for the authentication and delivery of such
Securities or coupons. Any portion of the text of any Security may be set forth
on the reverse thereof, with an appropriate reference thereto on the face of the
Security.

         Unless otherwise specified as contemplated by Section 301, Securities
in bearer form shall have interest coupons attached.

         The Trustee's certificate of authentication on all Securities shall be
in substantially the form set forth in this Article.

         The definitive Securities and coupons shall be printed, lithographed or
engraved on steel-engraved borders or may be produced in any other manner, all
as determined by the officers of the Company executing such Securities, as
evidenced by their execution of such Securities or coupons.

         SECTION 202. FORM OF TRUSTEE'S CERTIFICATE OF AUTHENTICATION.

         Subject to Section 612, the Trustee's certificate of authentication
shall be in substantially the following form:

                     TRUSTEE'S CERTIFICATE OF AUTHENTICATION

                                          By:
                                              ----------------------------------

<PAGE>   24

         SECTION 203. SECURITIES ISSUABLE IN GLOBAL FORM.

         If Securities of or within a series are issuable in global form, as
specified as contemplated by Section 301, then, any such Security shall
represent such of the Outstanding Securities of such series as shall be
specified therein and may provide that it shall represent the aggregate amount
of Outstanding Securities of such series from time to time endorsed thereon and
that the aggregate amount of Outstanding Securities of such series represented
thereby may from time to time be increased or decreased to reflect exchanges.
Any endorsement of a Security in global form to reflect the amount, or any
increase or decrease in the amount, of Outstanding Securities represented
thereby shall be made by the Trustee in such manner and upon instructions given
by such Person or Persons as shall be specified therein or in the Company Order
to be delivered to the Trustee pursuant to Section 303 or Section 305. Subject
to the provisions of Section 303 and, if applicable, Section 305, the Trustee
shall deliver and redeliver 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 303 or Section
305 has been, or simultaneously is, delivered, any instructions by the Company
with respect to endorsement or delivery or redelivery of a Security in global
form shall be in writing but need not comply with Section 102 and need not be
accompanied by an Opinion of Counsel.

         The provisions of the last sentence of Section 303 shall apply to any
Security represented by a Security in global form if such Security was never
issued and sold by the Company and the Company delivers to the Trustee the
Security in global form together with written instructions (which need not
comply with Section 102 and need not be accompanied by an Opinion of Counsel)
with regard to the reduction in the principal amount of Securities represented
thereby, together with the written statement contemplated by the last sentence
of Section 303.

         Notwithstanding the provisions of Section 308, unless otherwise
specified as contemplated by Section 301, payment of principal of (and premium,
if any) and interest, if any, on any Security in permanent global form shall be
made to the Person or Persons specified therein.

         Notwithstanding the provisions of Section 310 and except as provided in
the preceding paragraph, the Company, the Trustee and any agent of the Company
and the Trustee shall treat as the Holder of such principal amount of
Outstanding Securities represented by a permanent Global Security (i) in the
case of a permanent Global Security in registered form, the Holder of such
permanent Global Security in registered form, or (ii) in the case of a permanent
Global Security in bearer form, Euroclear or Cedel.

         SECTION 204. FORM OF LEGEND FOR BOOK-ENTRY SECURITIES.

         Any Global Security authenticated and delivered hereunder shall bear a
legend (which would be in addition to any other legends required in the case of
a Restricted Security) in substantially the following form:

         THIS SECURITY IS A GLOBAL SECURITY WITHIN THE MEANING OF THE INDENTURE
HEREINAFTER REFERRED TO AND IS REGISTERED IN THE NAME OF A DEPOSITORY OR A
NOMINEE THEREOF. THIS SECURITY MAY NOT BE EXCHANGED IN WHOLE OR IN PART FOR A
SECURITY REGISTERED, AND NO TRANSFER OF THIS SECURITY IN WHOLE OR IN PART MAY BE
REGISTERED, IN THE NAME OF ANY PERSON OTHER THAN SUCH DEPOSITORY OR ITS NOMINEE
EXCEPT IN THE LIMITED CIRCUMSTANCES DESCRIBED IN THE INDENTURE.

         UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF
THE DEPOSITORY TRUST COMPANY (55 WATER STREET, NEW YORK, NEW YORK 10041) TO THE
ISSUER OR ITS AGENT FOR REGISTRATION OF TRANSFER, EXCHANGE OR PAYMENT AND SUCH
CERTIFICATE ISSUED IN EXCHANGE FOR THIS CERTIFICATE IS REGISTERED IN THE NAME OF
CEDE & CO., OR SUCH OTHER NAME AS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF
THE DEPOSITORY TRUST COMPANY, ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE
OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL, SINCE THE REGISTERED OWNER HEREOF,
CEDE & CO., HAS AN INTEREST HEREIN.

                                 THE SECURITIES

                                       22
<PAGE>   28

         (19) the specific terms of the depository arrangement with respect
to any portion of a series of Securities to be represented by a Global Security
pursuant to Section 304; and

         (20) any other terms, conditions, rights and preferences (or
limitations on such rights and preferences) relating to the series (which terms
shall not be inconsistent with the requirements of the Trust Indenture Act or
the provisions of this Indenture).

         All Securities of any one series and the coupons appertaining to any
Bearer Securities of such series shall be substantially identical except, in the
case of Registered Securities, as to denomination and except as may otherwise be
provided in or pursuant to such Board Resolution (subject to Section 303) and
set forth in such Officers' Certificate or in any such indenture supplemental
hereto. Not all Securities of any one series need be issued at the same time,
and, unless otherwise provided, a series may be reopened for issuances of
additional Securities of such series.

         If any of the terms of the series are established by action taken
pursuant to one or more Board Resolutions, such Board Resolutions shall be
delivered to the Trustee at or prior to the delivery of the Officers'
Certificate setting forth the terms of the series.

         SECTION 302. DENOMINATIONS.

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

         SECTION 303. EXECUTION, AUTHENTICATION, DELIVERY AND DATING.

         The Securities and any coupons appertaining thereto shall be executed
on behalf of the Company by any one of the following: its Chairman, Chief
Executive Officer, its President or one of its Vice Presidents, and attested by
one of its Vice Presidents or its Secretary or one of its Assistant Secretaries.
The signature of any of these officers on the Securities or coupons may be
manual or facsimile.

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

         At any time and from time to time after the execution and delivery of
this Indenture, the Company may deliver Securities of any series together with
any coupon appertaining thereto, executed by the Company to the Trustee for
authentication, together with a Company Order for the authentication and
delivery of such Securities, and the Trustee in accordance with such Company
Order shall authenticate and make available for delivery such Securities;
provided,

                                       23
<PAGE>   29

however, that, in connection with its original issuance, no Bearer Security
shall be mailed or otherwise delivered to any location in the United States: and
provided further that, unless otherwise specified with respect to any series of
Securities pursuant to Section 301, a Bearer Security may be delivered in
connection with its original issuance only if the Person entitled to receive
such Bearer Security shall have furnished a certificate in the form set forth in
EXHIBIT A-1 to this Indenture, dated no earlier than 15 days prior to the
earlier of the date on which such Bearer Security is delivered and the date on
which any temporary Security first becomes exchangeable for such Bearer Security
in accordance with the terms of such temporary Security and this Indenture. If
any Security shall be represented by a permanent global Bearer Security, then,
for purposes of this Section and Section 305, the notation of a beneficial
owner's interest therein upon original issuance of such Security or upon
exchange of a portion of a temporary Global Security shall be deemed to be
delivery in connection with its original issuance of such beneficial owner's
interest in such permanent Global Security. Except as permitted by Section 307,
the Trustee shall not authenticate and make available for delivery any Bearer
Security unless all appurtenant coupons for interest then matured have been
detached and canceled. If not all the Securities of any series are to be issued
at one time and if the Board Resolution or supplemental indenture establishing
such series shall so permit, such Company Order may set forth procedures
acceptable to the Trustee for the issuance of such Securities and determining
terms of particular Securities of such series such as interest rate, stated
maturity, date of issuance and date from which interest shall accrue.

         In authenticating such Securities, and accepting the additional
responsibilities under this Indenture in relation to such Securities, the
Trustee shall be entitled to receive, and (subject to TIA sections 315(a)
through 315(d)) shall be fully protected in relying upon, an Opinion of Counsel
stating:

         (a) that the form or forms of such Securities and any coupons have
been established in conformity with the provisions of this Indenture:

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

         (c) that such Securities, together with any coupons appertaining
thereto, when completed by appropriate insertions and executed and delivered by
the Company to the Trustee for authentication in accordance with this Indenture,
authenticated and made available for delivery by the Trustee in accordance with
this Indenture and issued by the Company in the manner and subject to any
conditions specified in such Opinion of Counsel, will constitute the legal,
valid and binding obligations of the Company, enforceable in accordance with
their terms, subject to applicable bankruptcy, insolvency, reorganization and
other similar laws of general applicability relating to or affecting the
enforcement of creditors' rights, to general equitable principles and to such
other qualifications as such counsel shall conclude do not materially affect the
rights of Holders of such Securities and any coupons;

         (d) that all laws and requirements in respect of the execution and
delivery by the Company of such Securities, any coupons and of the supplemental
indentures, if any, have been complied with and that authentication and delivery
of such Securities and any coupons and the

                                       24
<PAGE>   30

execution and delivery of the supplemental indenture, if any, by the Trustee
will not violate the terms of the Indenture;

         (e) that the Company has the corporate power to issue such
Securities and any coupons, and has duly taken all necessary corporate action
with respect to such issuance; and

         (f) that the issuance of such Securities and any coupons will not
contravene the articles of incorporation or by-laws of the Company or result in
any violation of any of the terms or provisions of any law or regulation or of
any indenture, mortgage or other agreement known to such Counsel by which the
Company is bound.

         Notwithstanding the provisions of Section 301 and of the preceding two
paragraphs, if not all the Securities of any series are to be issued at one
time, it shall not be necessary to deliver the Officers' Certificate otherwise
required pursuant to Section 301 or the Company Order and Opinion of Counsel
otherwise required pursuant to the preceding two paragraphs prior to or at the
time of issuance of each Security, but such documents shall be delivered prior
to or at the time of issuance of the first Security of such series.

         The Trustee shall not be required to authenticate and make available
for delivery any such Securities if the issue of such Securities pursuant to
this Indenture will affect the Trustee's own rights, duties or immunities under
the Securities and this Indenture or otherwise in a manner which is not
reasonably acceptable to the Trustee.

         Each Registered Security shall be dated the date of its authentication
and each Bearer Security shall be dated as of the date specified as contemplated
by Section 301.

         No Security or coupon shall be entitled to any benefit under this
Indenture or be valid or obligatory for any purpose unless there appears on such
Security a certificate of authentication substantially in the form provided for
herein duly executed by the Trustee by manual signature of an authorized
signatory, and such certificate upon any Security shall be conclusive evidence,
and the only evidence, that such Security has been duly authenticated and
delivered hereunder and is entitled to the benefits of this Indenture.
Notwithstanding the foregoing, if any Security shall have been authenticated and
delivered hereunder but never issued and sold by the Company, and the Company
shall deliver such Security to the Trustee for cancellation as provided in
Section 311 together with a written statement (which need not comply with
Section 102 and need not be accompanied by an Opinion of Counsel) stating that
such Security has never been issued and sold by the Company, for all purposes of
this Indenture such Security shall be deemed never to have been authenticated
and delivered hereunder and shall never be entitled to the benefits of this
Indenture.

         SECTION 304. BOOK-ENTRY SECURITIES.

         (a) The Securities of a series may be issuable in whole or in part
in the form of one or more Global Securities ("Book-Entry Securities") deposited
with, or on behalf of, a Depository (the "Depository"). In the case of
Book-Entry Securities, one or more Global Securities will be issued in a
denomination or aggregate

                                       25
<PAGE>   31

denomination equal to the portion of the aggregate principal amount of
Outstanding Securities of the series to be represented by such Global Security
or Global Securities. Unless otherwise provided as contemplated by Section 301,
the additional provisions set forth in this Section 304 shall apply to
Book-Entry Securities.

         (b) Book-Entry Securities will be deposited with, or on behalf of,
the Depository, and registered in the name of the Depository's nominee, for
credit to the respective accounts of institutions that have accounts with the
Depository or its nominee ("Participants"); provided that Book-Entry Securities
purchased by persons outside the United States may be credited to or through
accounts maintained at the Depository by or on behalf of Euroclear or Cedel. The
accounts to be credited will be designated by the underwriters or agents of such
Securities or, if such Securities are offered and sold directly by the Company,
by the Company. Ownership of beneficial interests in Book-Entry Securities will
be limited to Persons that may hold interests through Participants and will be
shown on records maintained by the Depository or its nominee for such Book-Entry
Security. Participants shall have no rights under this Indenture or any
indenture supplemental hereto with respect to any Book-Entry Security held on
their behalf by the Depository, or the Trustee as its custodian, or under the
Book-Entry Security, and the Depository may be treated by the Company, the
Trustee and any agent of the Company or the Trustee as the absolute owner of the
Book-Entry Security for all purposes whatsoever. Notwithstanding the foregoing,
nothing in this Indenture or any such indenture supplemental shall prevent the
Company, the Trustee or any agent of the Company or the Trustee from giving
effect to any written certification, proxy or other authorization furnished by
the Depository or impair, as between the Depository and its Participants, the
operation of customary practices governing the exercise of the rights of a
Holder of any Security.

         (c) Transfers of Book-Entry Securities shall be limited to
transfers in whole, but not in part, to the Depository, its successors or their
respective nominees. Interests of beneficial owners in Book-Entry Securities may
be transferred or exchanged for Bearer Securities only if (i) the Depository
advises the Trustee in writing that it is no longer willing or able to discharge
properly its responsibilities with respect to such Book-Entry Security and it is
unable to locate a qualified successor, (ii) the Company, at its option, elects
to terminate the book-entry system by executing and delivering to the Trustee
and the Depository a notice to such effect, or (iii) there shall have occurred
and be continuing a Default or Event of Default with respect to the Securities
represented by such Book-Entry Security.

         (d) In connection with any transfer or exchange of a portion of
the beneficial interest in any Book-Entry Security to beneficial owners pursuant
to paragraph (c) above, the Security Registrar shall (if one or more Bearer
Securities are to be issued) reflect on its books and records the date and a
decrease in the principal amount of the Book-Entry Security in an amount equal
to the principal amount of the beneficial interest in the Book-Entry Security to
be transferred, and the Company shall execute, and the Trustee shall
authenticate and deliver, one or more Bearer Securities of like tenor and
principal amount of authorized denominations.

         (e) In connection with the transfer of Book-Entry Securities as an
entirety to beneficial owners pursuant to paragraph (c) above, the Book-Entry
Securities shall be deemed to be surrendered to the Trustee for cancellation and
the Company shall execute, and the Trustee shall authenticate and deliver, to
each beneficial owner identified by the Depository in exchange

                                       26
<PAGE>   32

for its beneficial interest in the Book-Entry Securities, an equal aggregate
principal amount of Bearer Securities of like tenor of authorized denominations.

         (f) The Holder of any Book-Entry Security may grant proxies and
otherwise authorize any person, including Participants and Persons that may hold
interests through Participants, to take any action which a Holder is entitled to
take under the applicable Indenture or the Securities.

         SECTION 305. TEMPORARY SECURITIES.

         Pending the preparation of definitive Securities of any series, the
Company may execute, and upon Company Order the Trustee shall authenticate and
deliver, temporary Securities which are typewritten, printed, lithographed,
engraved or otherwise produced by any combination of these methods, in any
authorized denomination, substantially of the tenor of the definitive Securities
in lieu of which they are issued, in registered form or, if authorized, in
bearer form with one or more coupons or without coupons, and with such
appropriate insertions, omissions, substitutions and other variations as the
officers executing such Securities may determine, as evidenced by their
execution of such Securities. Such temporary Securities may be in global form.

         Except in the case of temporary Securities in global form that are not
issued as Book-Entry Securities as provided in Section 304 (which shall be
exchanged in accordance with the provisions of the following paragraphs), if
temporary Securities of any series are issued, the Company will cause definitive
Securities of that series to be prepared without unreasonable delay. After the
preparation of definitive Securities of such series, the temporary Securities of
such series shall be exchangeable for definitive Securities of such series upon
surrender of the temporary Securities of such series at the office or agency of
the Company in a Place of Payment for that series, without charge to the Holder.
Upon surrender for cancellation of any one or more temporary Securities of any
series (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 the same series of
authorized denominations; provided, however, that no Bearer Security shall be
delivered in exchange for a temporary Registered Security; and provided further
that a Bearer Security shall be delivered in exchange for a temporary Bearer
Security only in compliance with the conditions set forth in Section 303. 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.

         If temporary Securities of any series are issued in global form (other
than Securities issued as Book-Entry Securities as provided in Section 304), any
such temporary Global Security shall, unless otherwise provided therein, be
delivered to the London office of a depositary or common depositary (the "Common
Depositary"), for the benefit of Euroclear and Cedel, for credit to the
respective accounts of the beneficial owners of such Securities (or to such
other accounts as they may direct).

         Without unnecessary delay but in any event not later than the date
specified in, or determined pursuant to the terms of, any such temporary Global
Security that is not issued as a

                                       27
<PAGE>   33

Book-Entry Security as provided in Section 304 (the "Exchange Date"), the
Company shall deliver to the Trustee definitive Securities, in aggregate
principal amount equal to the principal amount of such temporary Global
Security, executed by the Company. On or after the Exchange Date such temporary
Global Security shall be surrendered by the Common Depositary to the Trustee, as
the Company's agent for such purpose, to be exchanged, in whole or from time to
time in part, for definitive Securities without charge and the Trustee shall
authenticate and deliver, in exchange for each portion of such temporary Global
Security, an equal aggregate principal amount of definitive Securities of the
same series of authorized denominations and of like tenor as the portion of such
temporary Global Security to be exchanged. The definitive Securities to be
delivered in exchange for any such temporary Global Security shall be in bearer
form, registered form, permanent global bearer form or permanent global
registered form, or any combination thereof, as specified as contemplated by
Section 301, and, if any combination thereof is so specified, as requested by
the beneficial owner thereof; provided, however, that, unless otherwise
specified in such temporary Global Security, upon such presentation by the
Common Depositary, such temporary Global Security is accompanied by a
certificate dated the Exchange Date or a subsequent date and signed by Euroclear
as to the portion of such temporary Global Security held for its account then to
be exchanged and a certificate dated the Exchange Date or a subsequent date and
signed by Cedel as to the portion of such temporary Global Security held for its
account then to be exchanged, each in the form set forth in EXHIBIT A-2 to this
Indenture (or in such other form as may be established pursuant to Section 301);
and provided further that Bearer Securities shall be delivered in exchange for a
portion of a temporary Global Security only in compliance with the requirements
of Section 303.

         Unless otherwise specified in such temporary Global Security that is
not issued as a Book-Entry Security as provided in Section 304, the interest of
a beneficial owner of Securities of a series in a temporary Global Security
shall be exchanged for definitive Securities of the same series and of like
tenor following the Exchange Date when the account holder instructs Euroclear or
Cedel, as the case may be, to request such exchange on his behalf and delivers
to Euroclear or Cedel, as the case may be, a certificate in the form set forth
in EXHIBIT A-1 to this Indenture (or in such other form as may be established
pursuant to Section 301), dated no earlier than 15 days prior to the Exchange
Date, copies of which certificate shall be available from the offices of
Euroclear and Cedel, the Trustee, any Authenticating Agent appointed for such
series of Securities and each Paying Agent. Unless otherwise specified in such
temporary Global Security, any such exchange shall be made free of charge to the
beneficial owners of such temporary Global Security, except that a Person
receiving definitive Securities must bear the cost of insurance, postage,
transportation and the like in the event that such Person does not take delivery
of such definitive Securities in person at the offices of Euroclear or Cedel.
Bearer Securities in bearer form to be delivered in exchange for any portion of
a temporary Global Security shall be delivered only outside the United States.

         Until exchanged in full as hereinabove provided, the temporary
Securities of any series, including temporary Global Securities (whether or not
issued as Book-Entry Securities as provided in Section 304), shall in all
respects be entitled to the same benefits under this Indenture as definitive
Securities of the same series and of like tenor authenticated and delivered
hereunder, except that, unless otherwise specified as contemplated by Section
301, interest payable on a temporary Global Security (other than Securities
issued as Book-Entry Securities as

                                       28
<PAGE>   34

provided in Section 304) on an Interest Payment Date for Securities of such
series occurring prior to the applicable Exchange Date shall be payable to
Euroclear and Cedel on such Interest Payment Date upon delivery by Euroclear and
Cedel to the Trustee of a certificate or certificates in the form set forth in
EXHIBIT A-2 to this Indenture (or in such other form as may be established
pursuant to Section 301), for credit without further interest thereon on or
after such Interest Payment Date to the respective accounts of the Persons who
are the beneficial owners of such temporary Global Security on such Interest
Payment Date and who have each delivered to Euroclear or Cedel, as the case may
be, a certificate dated no earlier than 15 days prior to the Interest Payment
Date occurring prior to such Exchange Date in the form set forth in EXHIBIT A-1
to this Indenture (or in such other form as may be established pursuant to
Section 301). Notwithstanding anything to the contrary herein contained, the
certifications made pursuant to this paragraph shall satisfy the certification
requirements of the preceding two paragraphs of this Section and of the third
paragraph of Section 303 of this Indenture and the interests of the Persons who
are the beneficial owners of the temporary Global Security with respect to which
such certification was made will be exchanged for definitive Securities of the
same series and of like tenor on the Exchange Date or the date of certification
if such date occurs after the Exchange Date, without further act or deed by such
beneficial owners. Except as otherwise provided in this paragraph, no payments
of principal (or premium, if any) or interest, if any, owing with respect to a
beneficial interest in a temporary Global Security will be made unless and until
such interest in such temporary Global Security shall have been exchanged for an
interest in a definitive Security. Any interest so received by Euroclear and
Cedel and not paid as herein provided shall be returned to the Trustee
immediately prior to the expiration of two years after such Interest Payment
Date in order to be repaid to the Company in accordance with Section 1003.

         SECTION 306. REGISTRATION, REGISTRATION OF TRANSFER AND EXCHANGE.

         The Company shall cause to be kept at the Corporate Trust Office of the
Trustee a register for each series of Securities (the registers maintained in
such office of the Trustee and in any other office or agency designated pursuant
to Section 1002 being herein sometimes referred to as the "Security Register")
in which, subject to such reasonable regulations as it may prescribe, the
Company shall provide for the registration of Registered Securities and of
transfers of Registered Securities. The Trustee is hereby initially appointed
"Security Registrar" for the purpose of registering Registered Securities and
transfers of Registered Securities as herein provided.

         Except as otherwise described in this Article Three, upon surrender for
registration of transfer of any Registered Security of any series at the office
or agency in a Place of Payment for that 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, in each case, of any authorized denominations and of a like aggregate
principal amount.

         At the option of the Holder, Registered Securities of any series may be
exchanged for other Registered Securities of the same series, of any authorized
denominations and of a like aggregate principal amount, upon surrender of the
Registered Securities to be exchanged at such

                                       29
<PAGE>   35

office or agency. Whenever any Registered Securities are so surrendered for
exchange, the Company shall execute, and the Trustee shall authenticate and make
available for delivery, the Registered Securities which the Holder making the
exchange is entitled to receive. Unless otherwise specified with respect to any
series of Securities as contemplated by Section 301 or Section 304, Bearer
Securities may not be issued in exchange for Registered Securities.

         If (but only if) expressly permitted in or pursuant to the applicable
Board Resolution and (subject to Section 303) set forth in the applicable
Officers' Certificate, or in any indenture supplemental hereto, delivered as
contemplated by Section 301, at the option of the Holder, Bearer Securities of
any series may be exchanged for Registered Securities of the same series of any
authorized denomination and of a like aggregate principal amount and tenor, upon
surrender of the Bearer Securities to be exchanged at any such office or agency,
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, any such
permitted exchange may be effected if the Bearer Securities are accompanied by
payment in funds acceptable to the Company 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 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
1002, interest represented by coupons shall be payable only upon presentation
and surrender of those coupons at an office or agency located outside the United
States. Notwithstanding the foregoing, in case a Bearer Security of any series
is surrendered at any such office or agency in a permitted exchange for a
Registered Security of the same 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 relevant Interest Payment
Date, or (ii) any Special Record Date and before the opening of business at such
office or agency on the related proposed date for payment of Defaulted Interest,
such Bearer Security shall be surrendered without the coupon relating to such
Interest Payment Date or proposed date for payment, as the case may be, and
interest or Defaulted Interest, as the case may be, will 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 will be payable only to the Holder of such coupon when due in accordance
with the provisions of this Indenture.

         Whenever any Securities are so surrendered for exchange, the Company
shall execute, and the Trustee shall authenticate and deliver, the Securities
which the Holder making the exchange is entitled to receive, and the Trustee
shall cancel the Bearer Securities so transferred. In the case of an exchange of
Bearer Securities for an interest in a Book-Entry Security, the Security
Registrar shall reflect on the Register the date and an increase in the
principal amount of the Bearer Securities to be transferred, and the Trustee
shall cancel the Bearer Securities so transferred.

         Notwithstanding the foregoing, except as otherwise specified as
contemplated by Section 301, any permanent Global Security (other than
Securities issued as Book-Entry Securities as

                                       30
<PAGE>   36

provided in Section 304) shall be exchangeable only as provided in this
paragraph. If any beneficial owner of an interest in a permanent Global Security
is entitled to exchange such interest for Securities of such series and of like
tenor and principal amount of another authorized form and denomination, as
specified as contemplated by Section 301 and provided that any applicable notice
provided in the permanent Global Security shall have been given, then without
unnecessary delay but in any event not later than the earliest date on which
such interest may be so exchanged, the Company shall deliver to the Trustee
definitive Securities in aggregate principal amount equal to the principal
amount of such beneficial owner's interest in such permanent Global Security,
executed by the Company. On or after the earliest date on which such interests
may be so exchanged, such permanent Global Security shall be surrendered by the
Common Depositary or such other depositary 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 from time to time in part, for definitive
Securities without charge, and the Trustee shall authenticate and deliver, in
exchange for each portion of such permanent Global Security, an equal aggregate
principal amount of definitive Securities of the same series of authorized
denominations and of like tenor as the portion of such permanent Global Security
to be exchanged which, unless the Securities of the series are not issuable both
as Bearer Securities and as Registered Securities, as specified as contemplated
by Section 301, shall be in the form of Bearer Securities or Registered
Securities, or any combination thereof, as shall be specified by the beneficial
owner thereof; provided, however, that no such exchanges may occur during a
period beginning at the opening of business 15 days before any selection of
Securities to be redeemed and ending on the relevant Redemption Date if the
Security for which exchange is requested may be among those selected for
redemption; and provided further that no Bearer Security delivered in exchange
for a portion of a permanent Global Security shall be mailed or otherwise
delivered to any location in the United States. If a Registered Security is
issued in exchange for any portion of a permanent Global Security after the
close of business at the office or agency where such exchange occurs on (i) any
Regular Record Date and before the opening of business at such office or agency
on the relevant Interest Payment Date, or (ii) any Special Record Date and
before the opening of business at such office or agency on the related proposed
date for payment of Defaulted Interest, interest or Defaulted Interest, as the
case may be, will 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
will 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 permanent Global Security is 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 entitled 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 shall (if so required by the Company or the Security
Registrar) be duly endorsed, or be accompanied by a written instrument of
transfer, in form satisfactory to the Company and the Security Registrar, duly
executed by the Holder thereof or his attorney duly authorized in writing.

                                       31
<PAGE>   37

         No service charge shall be made for any registration of transfer or
exchange of Securities, but the Company may require payment of a sum sufficient
to pay all documentary, stamp, similar issue or transfer taxes or other
governmental charges that may be imposed in connection with any registration of
transfer or exchange of Securities, other than exchanges pursuant to Section
305, 906, 1107 or 1305 not involving any transfer.

         The Company shall not be required (i) to issue, register the transfer
of or exchange Securities of any series during a period beginning at the opening
of business 15 days before the day of the selection for redemption of Securities
of that series under Section 1103 or 1203 and ending at the close of business on
(A) if Securities of the series are issuable only as Registered Securities, the
day of the mailing of the relevant notice of redemption and (B) if Securities of
the series are issuable as Bearer Securities, the day of the first publication
of the relevant notice of redemption or, if Securities of the series are also
issuable as Registered Securities and there is no publication, the mailing of
the relevant notice of redemption, or (ii) to register the transfer of or
exchange any Registered Security so selected for redemption in whole or in part,
except the unredeemed portion of any Security being redeemed in part, or (iii)
to exchange any Bearer Security so selected for redemption except that such a
Bearer Security may be exchanged for a Registered Security of that series and
like tenor; provided that such Registered Security shall be simultaneously
surrendered for redemption, or (iv) to issue, register the transfer of or
exchange any Security which 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 307. 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 together with, in proper cases,
such security or indemnity as may be required by the Company or the Trustee to
save each of them and any agent of either of them harmless, the Company shall
execute and the Trustee shall authenticate and deliver in exchange therefor a
new Security of the same series and of like tenor and principal amount and
bearing a number not contemporaneously outstanding, with coupons corresponding
to the coupons, if any, appertaining to the surrendered Security, or, in case
any such mutilated 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,
with coupons corresponding to the coupons, if any, appertaining to the
surrendered Security, pay such Security or coupon.

         If there shall be delivered to the Company and to the Trustee (i)
evidence to their satisfaction of the destruction, loss or theft of any Security
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 Company
Order the Trustee shall authenticate and deliver, in lieu of any such destroyed,
lost or stolen Security or in exchange for the Security for which a destroyed,
lost or stolen coupon appertains (with all appurtenant coupons not destroyed,
lost or stolen), a new Security of the same series and of like tenor and
principal amount and bearing a number not contemporaneously outstanding, with
coupons corresponding to the coupons, if any, appertaining to such destroyed,

                                       32
<PAGE>   38

lost or stolen Security or to the Security to which such destroyed, lost or
stolen coupon appertains.

         Notwithstanding the provisions of the previous two paragraphs, in case
any such 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, with coupons corresponding to the coupons, if any,
appertaining to such mutilated, destroyed, lost or stolen Security or to the
Security to which such mutilated, destroyed, lost or stolen coupon appertains,
pay such Security or coupon; provided, however, that payment of principal of
(and premium, if any) and interest, if any, on Bearer Securities shall, except
as otherwise provided in Section 1002, be payable only at an office or agency
located outside the United States and, unless otherwise specified as
contemplated by Section 301, any interest on Bearer Securities shall be payable
only upon presentation and surrender of the coupons appertaining thereto.

         Upon the issuance of any new Security under this Section, the Company
may require the payment of a sum sufficient to pay all documentary, stamp or
similar issue or transfer taxes or other governmental charges that may be
imposed in relation thereto and any other expenses (including the fees and
expenses of the Trustee) connected therewith.

         Every new Security of any series with its coupons, if any, issued
pursuant to this Section in lieu of any mutilated, destroyed, lost or stolen
Security or in exchange for a Security to which a mutilated, destroyed, lost or
stolen coupon appertains, shall constitute an original additional contractual
obligation of the Company, whether or not the mutilated, destroyed, lost or
stolen Security and its coupons, if any, or the mutilated, 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 that series and their coupons, if any, duly issued
hereunder.

         The provisions of this Section 307 are exclusive and shall preclude (to
the extent lawful) all other rights and remedies with respect to the replacement
or payment of mutilated, destroyed, lost or stolen Securities or coupons.

         SECTION 308. PAYMENT OF INTEREST; INTEREST RIGHTS PRESERVED; OPTIONAL
INTEREST RESET.

         Unless otherwise provided as contemplated by Section 301 with respect
to any series of Securities, interest, if any, on any Registered Security which
is payable, and is punctually paid or duly provided for, on any Interest Payment
Date shall be paid to the Person in whose name such Security (or one or more
Predecessor Securities) is registered at the close of business on the Regular
Record Date for such interest at the office or agency of the Company maintained
for such purpose pursuant to Section 1002: provided, however, that each
installment of interest, if any, on any Registered Security may at the Company's
option be paid by (i) mailing a check for such interest, payable to or upon the
written order of the Person entitled thereto pursuant to Section 310, to the
address of such Person as it appears on the Security Register or (ii) transfer
to an account located in the United States maintained by the payee.

                                       33
<PAGE>   39

         Unless otherwise provided as contemplated by Section 301 with respect
to the Securities of any series, payment of interest, if any, may be made, in
the case of a Bearer Security, by transfer to an account located outside the
United States maintained by the payee.

         Unless otherwise provided as contemplated by Section 301, every
permanent Global Security (other than Book-Entry Securities issued as provided
in Section 304) will provide that interest, if any, payable on any Interest
Payment Date will be paid to each of Euroclear and Cedel with respect to that
portion of such permanent Global Security held for its account by the Common
Depositary, for the purpose of permitting each of Euroclear and Cedel to credit
the interest, if any, received by it in respect of such permanent Global
Security to the accounts of the beneficial owners thereof.

         Any interest on any Registered Security of any series which is payable,
but is not punctually paid or duly provided for, on any Interest Payment Date
shall forthwith cease to be payable to the Holder on the relevant Regular Record
Date by virtue of having been such Holder, and such defaulted interest and, if
applicable, interest on such defaulted interest (to the extent lawful) at the
rate specified in the Securities of such series (such defaulted interest and, if
applicable, interest thereon herein collectively called "Defaulted Interest")
may be paid by the Company, at its election in each case, as provided in
Subsection (1) or (2) below:

                  (1) The Company may elect to make payment of any Defaulted
Interest to the Persons in whose names the Registered Securities of such series
(or their respective Predecessor Securities) are registered at the close of
business on a Special Record Date for the payment of such Defaulted Interest,
which shall be fixed in the following manner. The Company shall notify the
Trustee in writing of the amount of Defaulted Interest proposed to be paid on
each Registered Security of such series and the date of the proposed payment,
and at the same time the Company shall deposit with the Trustee an amount of
money in the Currency in which the Securities of such series are payable (except
as otherwise specified pursuant to Section 301 for the Securities of such series
and except, if applicable, as provided in Sections 313(b), 313(d) and 313(e))
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 deposited to be
held in trust for the benefit of the Persons entitled to such Defaulted Interest
as in this Subsection provided. Thereupon the Trustee shall fix a Special Record
Date for the payment of such Defaulted Interest which shall be not more than 15
days and not less than 10 days prior to the date of the proposed payment and not
less than 10 days after the receipt by the Trustee of the notice of the proposed
payment. The Trustee shall promptly notify the Company of such Special Record
Date and, in the name and at the expense of the Company, shall cause notice of
the proposed payment of such Defaulted Interest and the Special Record Date
therefor to be given in the manner provided in Section 106, not less than 10
days prior to such Special Record Date. Notice of the proposed payment of such
Defaulted Interest and the Special Record Date therefor having been so given,
such Defaulted Interest shall be paid to the Persons in whose name the
Registered Securities of such series (or their respective Predecessor
Securities) are registered at the close of business on such Special Record Date
and shall no longer be payable pursuant to the following Subsection (2).

<PAGE>   40

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

         SECTION 309. Intentionally left blank.

         SECTION 310. 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 as the
owner of such Registered Security for the purpose of receiving payment of
principal of (and premium, if any) and (subject to Sections 306 and 308)
interest, if any, on such Security and for all other purposes whatsoever,
whether or not such Security 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.

         Title to any Bearer Security and any coupons appertaining thereto shall
pass by delivery. The Company, the Trustee and any agent of the Company or the
Trustee may treat the bearer of any Bearer Security and 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 such Security or coupons 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.

         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 Security in global form or for maintaining, supervising or
reviewing any records relating to such beneficial ownership interests.

         Notwithstanding the foregoing, with respect to any Global Security,
nothing herein shall prevent the Company, the Trustee, or any agent of the
Company or the Trustee, from giving effect to any written certification, proxy
or other authorization furnished by any depositary, as a Holder, with respect to
such Global Security or impair, as between such depositary and owners of
beneficial interests in such Global Security, the operation of customary
practices governing the exercise of the rights of such depositary (or its
nominee) as Holder of such Global Security.

         SECTION 311. CANCELLATION.

         All Securities and coupons surrendered for payment, redemption,
repayment at the option of the Holder, registration of transfer or exchange or
for credit against any current or future sinking fund payment shall, if
surrendered to any Person other than the Trustee, be delivered to the Trustee.
All Securities and coupons so delivered to the Trustee shall be promptly
canceled by it. The Company may at any time deliver to the Trustee for
cancellation any Securities

                                       35
<PAGE>   41

previously authenticated and delivered hereunder which the Company may have
acquired in any manner whatsoever, and may deliver to the Trustee (or to any
other Person for delivery to the Trustee) for cancellation any Securities
previously authenticated hereunder which the Company has not issued and sold,
and all Securities so delivered shall be promptly canceled by the Trustee. If
the Company shall so acquire any of the Securities, however, such acquisition
shall not operate as a redemption or satisfaction of the indebtedness
represented by such Securities unless and until the same are surrendered to the
Trustee for cancellation. No Securities shall be authenticated in lieu of or in
exchange for any Securities canceled as provided in this Section, except as
expressly permitted by this Indenture. All canceled Securities held by the
Trustee shall be disposed of by the Trustee in accordance with its customary
procedures, unless by Company Order the Company shall direct that canceled
Securities be returned to it.

         SECTION 312. COMPUTATION OF INTEREST.

         Except as otherwise specified as contemplated by Section 301 with
respect to any Securities, interest, if any, on the Securities of each series
shall be computed on the basis of a 360-day year of twelve 30-day months.

         SECTION 313. CURRENCY AND MANNER OF PAYMENTS IN RESPECT OF SECURITIES.

         (a) With respect to Registered Securities of any series not
permitting the election provided for in paragraph (b) below or the Holders of
which have not made the election provided for in paragraph (b) below, and with
respect to Bearer Securities of any series, except as provided in paragraph (d)
below, payment of the principal of (and premium, if any) and interest, if any,
on any Registered or Bearer Security of such series will be made in Dollars. The
provisions of this Section 313 may be modified or superseded with respect to any
Securities pursuant to Section 301.

         (b) It may be provided pursuant to Section 301 with respect to
Registered Securities of any series that Holders shall have the option, subject
to paragraph (d) below, to receive payments of principal of (or premium, if any)
or interest, if any, on such Registered Securities in any of the Currencies
which may be designated for such election by delivering to the Trustee a written
election with signature guaranties and in the applicable form established
pursuant to Section 301, not later than the close of business on the Election
Date immediately preceding the applicable payment date. If a Holder so elects to
receive such payments in any such Currency, such election will remain in effect
for such Holder or any transferee of such Holder until changed by such Holder or
such transferee by written notice to the Trustee (but any such change must be
made not later than the close of business on the Election Date immediately
preceding the next payment date to be effective for the payment to be made on
such payment date and no such change of election may be made with respect to
payments to be made on any Registered Security of such series with respect to
which an Event of Default has occurred or with respect to which the Company has
deposited funds pursuant to Article Four or Fourteen or with respect to which a
notice of redemption has been given by the Company or a notice of option to
elect repayment has been sent by such Holder or such transferee). Any Holder of
any such Registered Security who shall not have delivered any such election to
the Trustee not later than the close of business on

                                       36
<PAGE>   42

the applicable Election Date will be paid the amount due on the applicable
payment date in the relevant Currency as provided in Section 313(a). The Trustee
shall notify the Exchange Rate Agent as soon as practicable after the Election
Date of the aggregate principal amount of Registered Securities for which
Holders have made such written election.

         (c) Unless otherwise specified pursuant to Section 301, if the
election referred to in paragraph (b) above has been provided for pursuant to
Section 301, then, unless otherwise specified pursuant to Section 301, not later
than the fourth Business Day after the Election Date for each payment date for
Registered Securities of any series, the Exchange Rate Agent will deliver to the
Company a written notice specifying, in the Currency in which Registered
Securities of such series are payable, the respective aggregate amounts of
principal of (and premium, if any) and interest, if any, on the Registered
Securities to be paid on such payment date, specifying the amounts in such
Currency so payable in respect of the Registered Securities as to which the
Holders of Registered Securities of such series shall have elected to be paid in
another Currency as provided in paragraph (b) above. If the election referred to
in paragraph (b) above has been provided for pursuant to Section 301 and if at
least one Holder has made such election, then, unless otherwise specified
pursuant to Section 301, on the second Business Day preceding such payment date
the Company will deliver to the Trustee for such series of Registered Securities
an Exchange Rate Officers' Certificate in respect of the Dollar or Foreign
Currency payments to be made on such payment date. Unless otherwise specified
pursuant to Section 301, the Dollar or Foreign Currency amount receivable by
Holders of Registered Securities who have elected payment in a Currency as
provided in paragraph (b) above shall be determined by the Company on the basis
of the applicable Market Exchange Rate in effect on the third Business Day (the
"Valuation Date") immediately preceding each payment date, and such
determination shall be conclusive and binding for all purposes, absent manifest
error.

         (d) Unless otherwise specified pursuant to Section 301, if the
Holder of a Registered Security shall have elected to be paid in a Currency
other than Dollars as provided in paragraph (b) above, and a Conversion Event
occurs with respect to such elected Currency, such Holder shall receive payment
in Dollars.

         (e) The "Dollar Equivalent of the Foreign Currency" shall be
determined by the Exchange Rate Agent and shall be obtained for each subsequent
payment date by converting the specified Foreign Currency into Dollars at the
Market Exchange Rate on the Conversion Date.

         (f) The "Dollar Equivalent of the Currency Unit" shall be
determined as specified pursuant to Section 301. "Election Date" shall mean the
date for any series of Registered Securities as specified pursuant to clause
(11) of Section 301 by which the written election referred to in paragraph (b)
above may be made.

         All decisions and determinations of the Exchange Rate Agent regarding
the Dollar Equivalent of the Foreign Currency, the Dollar Equivalent of the
Currency Unit, the Market Exchange Rate and changes in the Specified Amounts as
specified above shall be in its sole discretion and shall, in the absence of
manifest error, be conclusive for all purposes and irrevocably binding upon the
Company, the Trustee and all Holders of such Securities

                                       37
<PAGE>   43

denominated or payable in the relevant Currency. The Exchange Rate Agent shall
promptly give written notice to the Company and the Trustee of any such decision
or determination.

         Except as otherwise provided pursuant to Section 301, in the event that
the Company determines in good faith that a Conversion Event has occurred with
respect to a Foreign Currency, the Company will immediately give written notice
thereof to the Trustee and to the Exchange Rate Agent (and the Trustee will
promptly thereafter give notice in the manner provided for in Section 106 to the
affected Holders) specifying the Conversion Date. Except as otherwise provided
pursuant to Section 301, in the event the Company so determines that a
Conversion Event has occurred with respect to any currency unit in which
Securities are payable, the Company will immediately give written notice thereof
to the Trustee and to the Exchange Rate Agent (and the Trustee will promptly
thereafter give notice in the manner provided for in Section 106 to the affected
Holders) specifying the Conversion Date and the Specified Amount of each
Component Currency on the Conversion Date. In the event the Company determines
in good faith that any subsequent change in any Component Currency as set forth
in the definition of Specified Amount above has occurred, the Company will
similarly give written notice to the Trustee and the Exchange Rate Agent.

         The Trustee shall be fully justified and protected in relying and
acting upon information received by it from the Company and the Exchange Rate
Agent and shall not otherwise have any duty or obligation to determine the
accuracy or validity of such information independent of the Company or the
Exchange Rate Agent.

         SECTION 314. APPOINTMENT AND RESIGNATION OF SUCCESSOR EXCHANGE RATE
AGENT.

         (a) Unless otherwise specified pursuant to Section 301, if and so
long as the Securities of any series may be payable in a Currency other than
Dollars, 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. The Company
will cause the Exchange Rate Agent to make the necessary foreign exchange
determinations at the time and in the manner specified pursuant to Section 301
for the purpose of determining the applicable rate of exchange and, if
applicable, for the purpose of converting Dollars into the applicable payment
Currency for the payment of principal (and premium, if any) and interest, if
any, pursuant to Section 313.

         (b) No resignation of the Exchange Rate Agent and no appointment
of a successor Exchange Rate Agent pursuant to this Section shall become
effective until the acceptance of appointment by the successor Exchange Rate
Agent as evidenced by a written instrument delivered to the Company and the
Trustee.

         (c) If the Exchange Rate Agent shall resign, be removed or become
incapable of acting, or if a vacancy shall occur in the office of the Exchange
Rate Agent 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 Exchange Rate Agent or Exchange Rate Agents with respect to the
Securities of that or those series (it being understood that any such successor

                                       38
<PAGE>   44

Exchange Rate Agent may be appointed with respect to the Securities of one or
more or all of such series and that, unless otherwise specified pursuant to
Section 301, at any time there shall only be one Exchange Rate Agent with
respect to the Securities of any particular series that are originally issued by
the Company on the same date and that are payable in the same Currency).

         SECTION 315. CUSIP NUMBERS.

         The Company in issuing the Securities may use "CUSIP" numbers (if then
generally in use) in addition to serial numbers, and, if so, the Trustee shall
use such "CUSIP" numbers in addition to serial numbers in notices 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 and that reliance may be placed
only on the serial or other identification numbers printed on the Securities,
and any such notice shall not be affected by any defect in or omission of such
"CUSIP" numbers. The Company will promptly notify the Trustee of any change in
the "CUSIP" numbers.

                           SATISFACTION AND DISCHARGE

         SECTION 401. SATISFACTION AND DISCHARGE OF INDENTURE.

         This Indenture shall, upon Company Request, cease to be of further
effect with respect to any series of Securities specified in such Company
Request (except as to any surviving rights of registration of transfer or
exchange of Securities of such series expressly provided for herein or pursuant
hereto) and the Trustee, on demand of and 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, if any, appertaining thereto (other
than (i) coupons appertaining to Bearer Securities surrendered for exchange for
Registered Securities and maturing after such exchange, whose surrender is not
required or has been waived as provided in Section 306, (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 307, (iii) coupons appertaining to
Securities called for redemption and maturing after the relevant Redemption
Date, whose surrender has been waived as provided in Section 1106, and (iv)
Securities and coupons of such series for whose payment money has theretofore
been deposited in trust with the Trustee or any Paying Agent or segregated and
held in trust by the Company and thereafter repaid to the Company or discharged
from such Trust, as provided in Section 1003) have been delivered to the Trustee
for cancellation; or

                                       39
<PAGE>   45

                      (B) all Securities of such series and, in the case of (i)
or (ii) below, any coupons appertaining thereto not theretofore delivered to the
Trustee for cancellation

                          (i) have become due and payable, or

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

                          (iii) if redeemable at the option of the Company, are
to be called for redemption within one year under arrangements satisfactory to
the Trustee for the giving of notice of redemption by the Trustee in the name,
and at the expense, of the Company, and the Company, in the case of (i), (ii) or
(iii) above, has irrevocably deposited or caused to be deposited with the
Trustee as trust funds in trust for such purpose an amount in the Currency in
which the Securities of such series are payable, sufficient to pay and discharge
the entire indebtedness on such Securities not theretofore delivered to the
Trustee for cancellation, for principal (and premium, if any) and interest, if
any, to the date of such deposit (in the case of Securities which have become
due and payable) or to the Stated Maturity or Redemption Date, as the case may
be:

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

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

         Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Company to the Trustee under Section 606, the obligations of
the Trustee to any Authenticating Agent under Section 612 and, if money shall
have been deposited with the Trustee pursuant to subclause (B) of Subsection (1)
of this Section, the obligations of the Trustee under Section 402 and the last
paragraph of Section 1003 shall survive.

         SECTION 402. APPLICATION OF TRUST MONEY.

         Subject to the provisions of the last paragraph of Section 1003, all
money deposited with the Trustee pursuant to Section 401 shall be held in trust
and applied by it, in accordance with the provisions of the Securities, the
coupons and this Indenture, to the payment, either directly or through any
Paying Agent (including the Company acting as its own Paying Agent) as the
Trustee may determine, to the Persons entitled thereto, of the principal (and
premium, if any) and interest, if any, for whose payment such money has been
deposited with the Trustee. If the Trustee or Paying Agent is unable to apply
any money or Government Obligations in accordance with Section 401 by reason of
any legal proceeding or by reason of any order or judgment of any court or
governmental authority enjoining, restraining or otherwise prohibiting such
application, the Company's obligations under this Indenture shall be revived and
reinstated as though no deposit had occurred pursuant to Section 401; provided
that if the Company has made any payment of principal of, premium, if any, or
interest on the Securities because of the

                                       40
<PAGE>   46

reinstatement of its obligations, the Company shall be subrogated to the rights
of the Holders of the Securities to receive such payment from the money or
Government Obligations held by the Trustee or Paying Agent.

                                  ARTICLE FIVE
                                    REMEDIES

         SECTION 501. EVENTS OF DEFAULT.

         "Event of Default", wherever used herein, means any one of the
following events (whatever the reason for such Event of Default and whether it
shall be voluntary or involuntary or be effected by operation of law or pursuant
to any judgment, decree or order of any court or any order, rule or regulation
of any administrative or government body):

                  (1) default in the payment of any interest on any Security

specifically dealt with elsewhere herein), and continuance of such default or

Company by the Trustee or to the Company and the Trustee by the Holders of at
least 25% in aggregate principal amount of the Securities then outstanding;

                  (5) there occurs with respect to any issue or issues of
Indebtedness of the Company or any Restricted Subsidiary having an outstanding
principal amount of $50,000,000 or more in the aggregate for all such issues of
all such Persons, whether such Indebtedness exists on the date of this Indenture
or is hereafter created, (a) an event of default that has caused the holder
thereof to declare such Indebtedness to be due and payable prior to its stated
maturity and such Indebtedness shall not have been discharged in full or such
acceleration shall not have been rescinded or annulled within 30 days of such
acceleration and/or (b) the failure to make a principal payment at the final
(but not any interim) fixed maturity and such defaulted payment shall not have
been made, waived or extended within 30 days of such payment default;

                  (6) failure by the Company or any of its Restricted
Subsidiaries to pay, bond or otherwise discharge within 60 days one or more

<PAGE>   47

                  (7) a court having jurisdiction in the premises enters a
decree or order for (i) relief in respect of the Company or any Restricted
Subsidiary in an involuntary case under any applicable Bankruptcy Law now or
hereafter in effect, (ii) appointment of a receiver, liquidator, assignee,
custodian, trustee, sequestrator or similar official of the Company or any
Restricted Subsidiary or for all or substantially all of the property and assets

                  (9) any other Event of Default provided with respect to
Securities of that series.

         SECTION 502. ACCELERATION OF MATURITY; RESCISSION AND ANNULMENT.

         If an Event of Default (other than as specified in Section 501(7) or
(8)) occurs and is continuing, the Trustee or the Holders of not less than 25%
in aggregate principal amount of the Securities of any series then outstanding
may, and the Trustee at the request of such Holders shall, declare the principal
of all of the outstanding Securities of such series immediately due and payable,
by a notice in writing to the Company (and to the Trustee if given by the
Holders) and, upon any such declaration, such principal shall become due and
payable immediately. If an Event of Default specified in Section 501(7) or (8)
above occurs and is continuing, then such principal 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 Securities.

         At any time after a declaration of acceleration under this Indenture,
but before a judgment or decree for payment of the money due has been obtained
by the Trustee, the Holders of a majority in aggregate principal amount of the
outstanding Securities, by written notice to the Company and the Trustee, may
rescind such declaration and its consequences if:

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

                           (A) all overdue interest on all Securities,

                           (B) all unpaid principal of (and premium, if any, on)
                  any outstanding Securities that has become due otherwise than
                  by such declaration of acceleration and interest thereon at
                  the rate borne by the Securities,

                                       42
<PAGE>   48

                           (C) to the extent that payment of such interest is
                  lawful, interest upon overdue interest and overdue principal
                  amount at the rate borne by the Securities, and

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

                  (ii) all Events of Default, other than the non-payment of
amounts of principal of (or premium, if any, on) or interest on the Securities
that have become due solely by such declaration of acceleration, have been cured
or waived.

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

         SECTION 503. COLLECTION OF INDEBTEDNESS AND SUITS FOR ENFORCEMENT BY
TRUSTEE.

         The Company covenants that if:

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

         (b) default is made in the payment of the principal of (or premium, if
any, on) any Security at the Stated Maturity or other maturity thereof,

the Company shall, upon demand of the Trustee, pay to the Trustee for the
benefit of the Holders of such Securities, the whole amount then due and payable
on such Securities for principal (and premium, if any) and interest, with
interest upon the overdue principal (and premium, if any) and, to the extent
that payment of such interest shall be legally enforceable, upon overdue
installments of interest, at the rate borne by the Securities; and, in addition
thereto, such further amount as shall be sufficient to cover the costs and
expenses of collection, including the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel and all other
amounts due to the Trustee under Section 606.

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

         If an Event of Default with respect to Securities of any series (or of
all series, as the case may be) occurs and is continuing, the Trustee may in its
discretion proceed to protect and enforce its rights and the rights of the
Holders by such appropriate judicial proceedings as the

                                       43
<PAGE>   49

Trustee shall deem most effectual to protect and enforce such rights, whether
for the specific enforcement of any covenant or agreement in this Indenture or
in aid of the exercise of any power granted herein, or to enforce any other
proper remedy subject, however, to Section 513. No recovery of any such judgment
upon any property of the Company shall affect or impair any rights, powers or
remedies of the Trustee or the Holders.

         SECTION 504. 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, upon the Securities or the property
of the Company or of 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
overdue principal, premium, if any, or interest) shall be entitled and
empowered, by intervention in such proceeding or otherwise,

                  (i) to file and prove a claim for the whole amount of
principal (and premium, if any) and interest owing and unpaid in respect of the
Securities, to take such other actions (including participating as a member,
voting or otherwise, of any official committee of creditors appointed in such
matter) 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 and counsel) and of the Holders allowed in such judicial
proceeding, and

                  (ii) to collect and receive any moneys or other property
payable or deliverable on any such claims and to distribute the same;

and any Custodian in any such judicial proceeding is hereby authorized by each
Holder to make such payments to the Trustee and, in the event that the Trustee
shall consent to the making of such payments directly to the Holders, to pay the
Trustee any amount due it for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, and any other
amounts due the Trustee under Section 606.

         Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Holder any plan of
reorganization, arrangement, adjustment or composition affecting the Securities
or the rights of any Holder thereof, or to authorize the Trustee to vote in
respect of the claim of any Holder in any such proceeding; provided, however,
that the Trustee may, on behalf of such Holders, vote for the election of a
trustee in bankruptcy or other similar official.

         SECTION 505. TRUSTEE MAY ENFORCE CLAIMS WITHOUT POSSESSION OF
SECURITIES.

         All rights of action and claims under this Indenture or the Securities
may be prosecuted and enforced by the Trustee without the possession of any of
the Securities or the production

                                       44
<PAGE>   50

thereof in any proceeding relating thereto, and any such proceeding instituted
by the Trustee shall be brought in its own name and as trustee of an express
trust, and any recovery of judgment shall, after provision for the payment of
the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel, be for the ratable benefit of the Holders of
the Securities in respect of which such judgment has been recovered.

         SECTION 506. APPLICATION OF MONEY COLLECTED.

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

         FIRST: To the payment of all amounts due the Trustee under Section 606;

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

         THIRD: The balance, if any, to the Person or Persons entitled thereto,
including the Company or any other obligor on the Securities, as their interests
may appear or as a court of competent jurisdiction may direct, provided that all
sums due and owing to the Holders and the Trustee have been paid in full as
required by this Indenture.

         SECTION 507. LIMITATION ON SUITS.

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

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

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

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

         (4) the Trustee for 30 days after its receipt of such notice,
request and offer of indemnity has failed to institute any such proceeding; and

                                       45
<PAGE>   51

         (5) no direction inconsistent with such written request has been
given to the Trustee during such 30-day period by the Holders of a majority or
more in principal amount of the Outstanding Securities of that series;

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

         SECTION 508. UNCONDITIONAL RIGHT OF HOLDERS TO RECEIVE PRINCIPAL,
PREMIUM AND INTEREST.

         Notwithstanding any other provision in this Indenture, the Holder of
any Security shall have the right, which is absolute and unconditional, to
receive payment of the principal of (and premium, if any) and (subject to
Section 308) interest, if any, on, such Security or payment of such coupon on
the respective Stated Maturities expressed in such Security or coupon (or, in
the case of redemption, on the Redemption Date) and to institute suit for the
enforcement of any such payment, and such rights shall not be impaired without
the consent of such Holder.

         SECTION 509. RESTORATION OF RIGHTS AND REMEDIES.

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

         SECTION 510. RIGHTS AND REMEDIES CUMULATIVE.

         Except as otherwise provided in Section 307, no right or remedy herein
conferred upon or reserved to the Trustee or to the Holders of Securities or
coupons is intended to be exclusive of any other right or remedy, and every
right and remedy shall, to the extent permitted by law, be cumulative and in
addition to every other right and remedy given hereunder or now or hereafter
existing at law or in equity or otherwise. The assertion or employment of any
right or remedy hereunder, or otherwise, shall not prevent the concurrent
assertion or employment of any other appropriate right or remedy.

         SECTION 511. DELAY OR OMISSION NOT WAIVER.

         No delay or omission of the Trustee or of any Holder of any Security 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

                                       46
<PAGE>   52

right and remedy given by this Article or by law to the Trustee or to the
Holders may be exercised from time to time, and as often as may be deemed
expedient, by the Trustee or by the Holders, as the case may be.

         SECTION 512. CONTROL BY HOLDERS.

         With respect to the Securities of any series, the Holders of not less
than a majority in principal amount of the Outstanding Securities of such 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, provided that in each case

         (1) such direction shall not be in conflict with any rule of law or
with this Indenture or expose the Trustee to personal liability;

         (2) the Trustee need not take any action which might involve it in
personal liability or be unjustly prejudicial to the Holders not consenting; and

         (3) subject to the provisions of the TIA Section 315, the Trustee
may take any other action deemed proper by the Trustee which is not inconsistent
with such direction.

         SECTION 513. WAIVER OF PAST DEFAULTS.

         Subject to Section 502, the Holders of not less than a majority in
principal amount of the Outstanding Securities of any series may on behalf of
the Holders of all the Securities of such series waive any past Default or Event
of Default under this Indenture, except a default in the payment of the
principal of (and premium, if any) or interest on any Note, or in respect of a
covenant or provision that under this Indenture cannot be modified or amended
without the consent of the Holder of each Note outstanding.

         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 Event of Default or impair any right consequent thereon.

         SECTION 514. UNDERTAKING FOR COSTS.

         All parties to this Indenture agree, and each Holder of Securities of
any series 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, suffered or omitted by it as Trustee, the filing by any party
litigant in such suit of an undertaking to pay the costs of such suit, and that
such court may in its discretion assess reasonable costs, including reasonable
attorneys fees 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 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 the
Outstanding Securities of any series, or to

                                       47
<PAGE>   53

any suit instituted by any Holder for the enforcement of the payment of the
principal of (or premium, if any) or interest on Securities of any series on or
after the respective Stated Maturities expressed in such Security (or, in the
case of redemption, on or after the Redemption Date); provided that neither this
Section 514 nor the Trust Indenture Act shall be deemed to authorize any court
to require such an undertaking or to make such an assessment in any suit
instituted by the Company.

         SECTION 515. WAIVER OF STAY OR EXTENSION LAWS.

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

                                   ARTICLE SIX
                                   THE TRUSTEE

         SECTION 601. NOTICE OF DEFAULTS.

         If a Default or an Event of Default occurs with respect to the
Securities of any series and is continuing and is known to the Trustee, the
Trustee shall mail to all Holders of the Securities notice of the Default or
Event of Default within 90 days after the occurrence thereof. Except in the case
of a Default or an Event of Default in payment of principal of (and premium, if
any, on) or interest on any Securities, the Trustee may withhold the notice to
the Holders if a committee of its trust officers in good faith determines that
withholding such notice is in the interests of the Holders.

         SECTION 602. CERTAIN RIGHTS OF TRUSTEE.

         Subject to the provisions of TIA Sections 315(a) through 315(d):

         (1) the Trustee may rely and shall be protected in acting or
refraining from acting upon any resolution, certificate, statement, instrument,

note, other evidence of indebtedness or other paper or document believed by it
to be genuine and to have been signed or presented by the proper party or
parties;

be sufficiently evidenced by a Company Request or Company Order and any
resolution of the Board of Directors may be sufficiently evidenced by a Board
Resolution;

                                       48
<PAGE>   54

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

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

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

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

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

         (8) the Trustee shall not be liable for any action taken, suffered
or omitted by it in good faith and reasonably believed by it to be authorized or
within the discretion or rights or powers conferred upon it by this Indenture;
and the Trustee shall not be deemed to have notice of any Default or Event of
Default, except in the case of an event of default involving failures by the
Company to pay principal, premium, if any, or interest on the Securities, unless
a Responsible Officer of the Trustee has actual knowledge thereof or unless
written notice of any event which is in fact such a default is received by the
Trustee at the Corporate Trust Office of the Trustee, and such notice references
the Company, the Securities or this Indenture.

         SECTION 603. TRUSTEE NOT RESPONSIBLE FOR RECITALS OR ISSUANCE OF
SECURITIES.

         The recitals contained herein and in the Securities, except for the
Trustee's certificate of authentication, and in any coupons shall be taken as
the statements of the Company, and neither the Trustee nor any Authenticating
Agent assumes any responsibility for their correctness. The Trustee makes no
representations as to the validity or sufficiency of this Indenture or of the
Securities or coupons. The Trustee shall not be accountable for the use or
application by the

                                       49
<PAGE>   55

Company of Securities or the proceeds thereof, except that the Trustee
represents that it is duly authorized to execute and deliver this Indenture,
authenticate the Securities and perform its obligations hereunder and that the
statements to be made by it in a Statement of Eligibility on Form T-1 supplied
to the Company are true and accurate, subject to the qualifications set forth
therein. Neither the Trustee nor any Authenticating Agent shall be accountable

         SECTION 604. MAY HOLD SECURITIES.

         The Trustee, any Authenticating Agent, any Paying Agent, any Security
Registrar or any other agent of the Company or of the Trustee, in its individual
or any other capacity, may become the owner or pledgee of Securities and coupons
and, subject to TIA Sections 310(b) and 311, may otherwise deal with the Company
with the same rights it would have if it were not Trustee, Authenticating Agent,
Paying Agent, Security Registrar or such other agent. The Trustee is permitted
to engage in other transactions; provided, however, that if it acquires any
conflicting interest it must eliminate such conflict or resign.

         SECTION 605. MONEY HELD IN TRUST.

         Money held by the Trustee in trust hereunder need not be segregated
from other funds except to the extent required by law. The Trustee shall be

         SECTION 606. COMPENSATION AND REIMBURSEMENT.

         The Company agrees:

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

services rendered by it hereunder (which compensation shall not be limited by
any provision of law in regard to the compensation of a trustee of an express
trust);

         (2) except as otherwise expressly provided herein, to reimburse
the Trustee upon its request for all reasonable expenses, disbursements and
advances incurred or made by the Trustee in accordance with any provision of

negligence or bad faith; and

         (3) to indemnify each of the Trustee or any predecessor Trustee
(and their respective directors, officers, employees and agents) for, and to
hold it harmless against, any and all loss, damage, claim, liability or expense,
incurred without negligence or bad faith on its part, arising out of or in
connection with the acceptance or administration of this trust, including the
costs and expenses of defending itself against any claim or liability in
connection with the exercise or performance of any of its powers or duties
hereunder.

                                       50
<PAGE>   56

         The obligations of the Company under this Section to compensate the
Trustee, to pay or reimburse the Trustee for expenses, disbursements and
advances and to indemnify and hold harmless the Trustee shall constitute
additional indebtedness hereunder and shall survive the satisfaction and
discharge of this Indenture and the resignation or removal of the Trustee. As
security for the performance of such obligations of the Company, the Trustee
shall have a claim prior to the Securities 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, if any) or interest on particular Securities.

         When the Trustee incurs expenses or renders services in connection with
an Event of Default specified in Section 501(7) or (8), the expenses (including
the reasonable charges and expenses of its counsel) of and the compensation for
such services are intended to constitute expenses of administration under
Bankruptcy Law.

         The provisions of this Section shall survive the termination of this
Indenture.

         SECTION 607. CORPORATE TRUSTEE REQUIRED; ELIGIBILITY; CONFLICTING
INTERESTS.

         There shall be at all times a Trustee hereunder which shall be eligible
to act as Trustee under TIA Section 310(a)(1) and which shall have an office in
The City of New York, and shall have a combined capital and surplus of at least
$100,000,000. If the Trustee does not have an office in The City of New York,
the Trustee may appoint an agent in The City of New York reasonably acceptable
to the Company to conduct any activities which the Trustee may be required under
this Indenture to conduct in The City of New York. If such corporation publishes
reports of condition at least annually, pursuant to law or to the requirements
of federal, state, territorial or District of Columbia supervising or examining
authority, then for the purposes of this Section 607, the combined capital and
surplus of such corporation shall be deemed to be its combined capital and
surplus as set forth in its most recent report of condition so published. If at
any time the Trustee shall cease to be eligible in accordance with the
provisions of this Section 607, it shall resign immediately in the manner and
with the effect hereinafter specified in this Article.

         SECTION 608. RESIGNATION AND REMOVAL; APPOINTMENT OF SUCCESSOR.

         (a) No resignation or removal of the Trustee and no appointment of
a successor Trustee pursuant to this Article shall become effective until the
acceptance of appointment by the successor Trustee under Section 609.

         (b) The Trustee may resign at any time with respect to the
Securities of one or more series by giving written notice thereof to the
Company. If the instrument of acceptance by a successor Trustee required by
Section 609 shall not have been delivered to the Trustee within 30 days after
the giving of such notice of resignation, the resigning Trustee may, at the
expense of the Company, petition any court of competent jurisdiction for the
appointment of a successor Trustee with respect to the Securities of such
series.

                                       51
<PAGE>   57

         (c) The Trustee may be removed at any time with respect to the
Securities of any series by Act of the Holders of not less than a majority in
principal amount of the Outstanding Securities of such series, delivered to the
Trustee and the Company. If an instrument of acceptance by a successor Trustee
shall not have been delivered to the Trustee within 30 days after the giving of
such notice of removal, the removed Trustee may, at the expense of the Company,
petition a court of competent jurisdiction for the appointment of a successor
Trustee.

         (d) If at any time;

             (1) the Trustee shall fail to comply with the provisions of TIA
Section 310(b) after written request therefor by the Company or by any Holder
who has been a bona fide Holder of a Security for at least six months, or

             (2) the Trustee shall cease to be eligible under Section 607 and
shall fail to resign after written request therefor by the Company or by any
Holder who has been a bona fide Holder of a Security for at least six months, or

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

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

         (e) If the Trustee shall resign, be removed or become incapable of
acting, or if a vacancy shall occur in the office of Trustee for any cause, with
respect to the Securities of one or more series, the Company, by a Board
Resolution, shall promptly appoint a successor Trustee or Trustees with respect
to the Securities of that or those series (it being understood that any such
successor Trustee may be appointed with respect to the Securities of one or more
or all of such series and that at any time there shall be only one Trustee with
respect to the Securities of any particular series). If, within one year after
such resignation, removal or incapability, or the occurrence of such vacancy, a
successor Trustee with respect to the Securities of any series shall be
appointed by Act of the Holders of a majority in principal amount of the
Outstanding Securities of such series delivered to the Company and the retiring
Trustee, the successor Trustee so appointed shall, forthwith upon its acceptance
of such appointment in accordance with Section 609, 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 within 30 days of resignation or
removal of the Trustee, no successor Trustee with respect to the Securities of
any series shall have been so appointed by the Company or the Holders and
accepted appointment in the manner hereinafter provided, any Holder who has been
a bona fide Holder of a Security of such series for

                                       52
<PAGE>   58
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.

         (f) The Company shall give notice of each resignation and each
removal of the Trustee with respect to the Securities of any series and each
appointment of a successor Trustee with respect to the Securities of any series
to the Holders of Securities of such series in the manner provided for in
Section 106. Each notice shall include the name of the successor Trustee with
respect to the Securities of such series and the address of its Corporate Trust
Office.

         SECTION 609. ACCEPTANCE OF APPOINTMENT BY SUCCESSOR.

         (a) Every successor Trustee appointed hereunder shall execute,
acknowledge and deliver to the Company and to the retiring Trustee an instrument
accepting such appointment, and thereupon the resignation or removal of the
retiring Trustee shall become effective and such successor Trustee, without any
further act, deed or conveyance, shall become vested with all the rights,
powers, trusts and duties of the retiring Trustee; provided, however, that the
retiring Trustee shall continue to be entitled to the benefit of Section 606;
but, on the request of the Company or the successor Trustee, such retiring
Trustee shall, upon payment of its charges, execute and deliver an instrument
transferring to such successor Trustee all the rights, powers and trusts of the
retiring Trustee and shall duly assign, transfer and deliver to such successor
Trustee all property and money held by such retiring Trustee hereunder.

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

                                       53

Trustee hereunder with respect to the Securities of that or those series to
which the appointment of such successor Trustee relates. Whenever there is a
successor Trustee with respect to one or more (but less than all) series of
securities issued pursuant to this Indenture, the terms "Indenture" and
"Securities" shall have the meanings specified in the provisos to the respective
definitions of those terms in Section 101 which contemplate such situation.

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

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

         SECTION 610. MERGER, CONVERSION, CONSOLIDATION OR SUCCESSION TO
BUSINESS.

         Any corporation into which the Trustee may be merged or converted or
with which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
corporation succeeding to all or substantially all of the corporate trust
business of the Trustee, shall be the successor of the Trustee hereunder,
provided such corporation shall be otherwise qualified and eligible under this
Article, without the execution or filing of any paper or any further act on the
part of any of the parties hereto. In case any Securities shall have been
authenticated, but not delivered, by the Trustee then in office, any successor
by merger, conversion or consolidation to such authenticating Trustee may adopt
such authentication and deliver the Securities so authenticated with the same
effect as if such successor Trustee had itself authenticated such Securities. In
case any of the Securities shall not have been authenticated by such predecessor
Trustee, any successor Trustee may authenticate such Securities either in the
name of any predecessor hereunder or in the name of the successor Trustee. In
all such cases such certificates shall have the full force and effect which this
Indenture provides for the certificate of authentication of the Trustee;
provided, however, that the right to adopt the certificate of authentication of
any predecessor Trustee or to authenticate Securities in the name of any
predecessor Trustee shall apply only to its successor or successors by merger,
conversion or consolidation.

         SECTION 611. APPOINTMENT OF AUTHENTICATING AGENT.

         At any time when any of the Securities remain Outstanding, the Trustee
may appoint an Authenticating Agent or Agents with respect to one or more series
of Securities which shall be authorized to act on behalf of the Trustee to
authenticate Securities of such series and the Trustee shall give written notice
of such appointment to all Holders of Securities of the series with respect to
which such Authenticating Agent will serve, in the manner provided for in
Section 106. 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. Any such appointment shall be evidenced
by an instrument in writing signed by a Responsible Officer of the Trustee, and
a copy of such instrument shall be promptly furnished to the Company. Wherever
reference is made in this Indenture to the authentication and delivery of
Securities by

                                       54
<PAGE>   60

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 shall be
acceptable to the Company and shall at all times be a corporation organized and
doing business under the laws of the United States of America, any state thereof
or the District of Columbia, authorized under such laws to act as Authenticating
Agent, having a combined capital and surplus of not less than $50,000,000 and
subject to supervision or examination by federal or state authority. If such
corporation publishes reports of condition at least annually, pursuant to law or
to the requirements of said supervising or examining authority, then for the
purposes of this Section, the combined capital and surplus of such corporation
shall be deemed to be its combined capital and surplus as set forth in its most
recent report of condition so published. If at any time an Authenticating Agent
shall cease to be eligible in accordance with the provisions of this Section, 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 the corporate agency or
corporate trust business of an Authenticating Agent, shall continue to be an
Authenticating Agent, provided such corporation shall be otherwise eligible
under this Section, without the execution or filing of any paper or any further
act on the part of the Trustee or the Authenticating Agent.

         An Authenticating Agent may resign at any time by giving written notice
thereof to the Trustee and to the Company. The Trustee may at any time terminate
the agency of an Authenticating Agent by giving written notice thereof to such
Authenticating Agent and to the Company. Upon receiving such a notice of
resignation or upon such a termination, or in case at any time such
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, the Trustee may appoint a successor Authenticating
Agent which shall be acceptable to the Company and shall give written notice of
such appointment to all Holders of Securities of the series with respect to
which such Authenticating Agent will serve, in the manner provided for in
Section 106. Any successor Authenticating Agent upon acceptance of its
appointment hereunder shall become vested with all the rights, powers and duties
of its predecessor hereunder, with like effect as if originally named as an
Authenticating Agent. No successor Authenticating Agent shall be appointed
unless eligible under the provisions of this Section.

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

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

         Dated:............

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

presentation and surrender of the several coupons for such interest installments
as are evidenced thereby as they severally mature.

         SECTION 1002. MAINTENANCE OF OFFICE OR AGENCY.

         If the Securities of a series are issuable only as Registered
Securities, the Company will maintain in each Place of Payment for any series of
Securities an office or agency where Securities of that series may be presented

for registration of transfer or exchange, where Securities of that series that
are convertible or exchangeable may be surrendered for conversion or exchange,
as applicable and where notices and demands to or upon the Company in respect of
the Securities of that series and this Indenture may be served.

         If Securities of a series are issuable as Bearer Securities, the
Company will maintain (A) in The City of New York, an office or agency where any
Registered Securities of that series may be presented or surrendered for
payment, where any Registered Securities of that series may be surrendered for
registration of transfer, where Securities of that series may be surrendered for

of that series and related coupons may be presented and surrendered for payment;
provided, however, that, if the Securities of that series are listed on any
stock exchange located outside the United States and such stock exchange shall
so require, the Company will maintain a Paying Agent for the Securities of that
series in any required city located outside the United States so long as the

location, and any change in the location, of such office or agency. If at any
time the Company shall fail to maintain any such required office or agency or
shall fail to furnish the Trustee with the address thereof, such presentations,
surrenders, notices and demands may be made or served at the Corporate Trust
Office of the Trustee, except that Bearer Securities of any series and the
related coupons may be presented and surrendered for payment at the offices
specified in the Security, in London, and the Company hereby appoints the same
as its agents to receive such respective presentations, surrenders, notices and
demands.

                                       62
<PAGE>   68

         Unless otherwise specified with respect to any Securities pursuant to
Section 301, no payment of principal, premium or interest on Bearer Securities
shall be made at any office or agency of the Company 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, that, if
the Securities of a series are payable in Dollars, payment of principal of (and
premium, if any) and interest, if any, on any Bearer Security shall be made at
the office of the Company's Paying Agent in The City of New York, if (but only
if) payment in Dollars of the full amount of such principal, premium or
interest, as the case may be, at all offices or agencies 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
any such designation; 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 accordance with the requirements set forth above for Securities of
any series for such purposes. The Company will 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 specified with respect to
any Securities as contemplated by Section 301 with respect to a series of
Securities, the Company hereby designates as a Place of Payment for each series
of Securities the office or agency of the Company in the Borough of Manhattan.
The City of New York, and initially appoints the Trustee at its Corporate Trust
Office as Paying Agent in such city and as its agent to receive all such
presentations, surrenders, notices and demands.

         Unless otherwise specified with respect to any Securities pursuant to
Section 301, if and so long as the Securities of any series may be payable in a
Currency other than Dollars, or so long as it is required under any other
provision of the 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 1003. 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 and any related coupons, it will, on or
before each due date of the principal of (or premium, if any) or interest, if
any, on any of the Securities of that series, segregate and hold in trust for
the benefit of the Persons entitled thereto a sum in the Currency in which the
Securities of such series are payable (except as otherwise specified pursuant to
Section 301 for the Securities of such series and except, if applicable, as
provided in Sections 313(b), 313(d) and 313(e)) sufficient to pay the principal
of (or premium, if any) or interest, if any, on Securities of such series so
becoming due until such sums shall be paid to such Persons or otherwise disposed
of as herein provided and will promptly notify the Trustee of its action or
failure so to act.

         Whenever the Company shall have one or more Paying Agents for any
series of Securities and any related coupons, it will, prior to or on each due
date of the principal of (or premium, if any) or interest, if any, on any
Securities of that series, deposit with a Paying Agent

                                       63
<PAGE>   69

a sum (in the Currency described in the preceding paragraph) sufficient to pay
the principal (or premium, if any) or interest, if any, so becoming due, such
sum to be held in trust for the benefit of the Persons entitled to such
principal, premium or interest, 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 will cause each Paying Agent (other than the Trustee) for
any series of Securities to execute and deliver to the Trustee an instrument in
which such Paying Agent shall agree with the Trustee, subject to the provisions
of this Section, that such Paying Agent will:

         (1) hold all sums held by it for the payment of the principal of
(and premium, if any) and interest, if any, on 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 herein provided;

         (2) give the Trustee notice of any default by the Company (or any
other obligor upon the Securities of such series) in the making of any payment
of principal of (or premium, if any) or interest, if any, on 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 trusts as those upon which 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 provided in the Securities of any series, any money deposited
with the Trustee or any Paying Agent, or then held by the Company, in trust for
the payment of the principal of (or premium, if any) or interest, if any, on any
Security of any series, or any coupon appertaining thereto, and remaining
unclaimed for two years after such principal, premium or interest has become due
and payable shall be paid to the Company on Company Request, or (if then held by
the Company) shall be discharged from such trust; and the Holder of such
Security or coupon 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, may at
the expense of the Company cause to be published once, in an Authorized
Newspaper, notice that such money remains unclaimed and that, after a date
specified therein, which shall not be less than 30 days from the date of such
publication, any unclaimed balance of such money then remaining will be repaid
to the Company.

         SECTION 1004. 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 that of each Restricted

                                       64
<PAGE>   70

Subsidiary and the corporate rights (charter and statutory), licenses and
franchises of the Company and each Restricted Subsidiary; provided, however,
that the Company shall not be required to preserve any such existence (except of
the Company), right, license 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 each of its Restricted
Subsidiaries, taken as a whole.

         SECTION 1005. PAYMENT OF TAXES AND OTHER CLAIMS.

         The Company shall pay or discharge or cause to be paid or discharged,
before the same shall become delinquent, all material taxes, assessments and
governmental charges levied or imposed upon the Company or any Restricted
Subsidiary or upon the income, profits or property of the Company or any
Restricted Subsidiary; provided, however, that the Company shall not be required
to pay or discharge or cause to be paid or discharged any such tax, assessment
or charge whose amount, applicability or validity is being contested in good
faith by appropriate proceedings.

         SECTION 1006. OTHER COVENANTS.

         The applicable prospectus supplement will describe any material
covenants in respect of a series of Securities.

         SECTION 1007. STATEMENT AS TO COMPLIANCE.

         The Company will deliver to the Trustee, within 120 days after the end
of each fiscal year ending after the date hereof, a brief certificate of its
principal executive officer, principal financial officer or principal accounting
officer stating whether, to such officer's knowledge, the Company is in
compliance with all covenants and conditions to be complied with by it under
this Indenture. For purposes of this Section 1007, such compliance shall be
determined without regard to any period of grace or requirement of notice under
this Indenture.

                                 ARTICLE ELEVEN
                            REDEMPTION OF SECURITIES

         SECTION 1101. APPLICABILITY OF ARTICLE.

         Securities of any series which are redeemable before their Stated
Maturity shall be redeemable in accordance with the terms of such Securities and
(except as otherwise specified as contemplated by Section 301 for Securities of
any series) in accordance with this Article.

         SECTION 1102. ELECTION TO REDEEM; NOTICE TO TRUSTEE.

         The election of the Company to redeem any Securities shall be evidenced
by or pursuant to a Board Resolution. In case of any redemption at the election
of the Company, the Company shall, at least 60 days prior to the Redemption Date
fixed by the Company (unless a shorter

                                       65
<PAGE>   71

notice shall be satisfactory to the Trustee), notify the Trustee of such
Redemption Date and of the principal amount of Securities of such series to be
redeemed and shall deliver to the Trustee such documentation and records as
shall enable the Trustee to select the Securities to be redeemed pursuant to
Section 1103. In the case of any redemption of Securities prior to the
expiration of any restriction on such redemption provided in the terms of such
Securities or elsewhere in this Indenture, the Company shall furnish the Trustee
with an Officers' Certificate evidencing compliance with such restriction.

         SECTION 1103. SELECTION BY TRUSTEE OF SECURITIES TO BE REDEEMED.

         If less than all the Securities of any series are to be redeemed, the
particular Securities to be redeemed shall be selected not more than 60 days
prior to the Redemption Date by the Trustee, from the Outstanding Securities of
such series not previously called for redemption, by such method as the Trustee
shall deem fair and appropriate and which may provide for the selection for
redemption of portions of the principal of Securities of such series; provided,
however, that no such partial redemption shall reduce the portion of the
principal amount of a Security not redeemed to less than the minimum authorized
denomination for Securities of such series established pursuant to Section 301.

         The Trustee shall promptly notify the Company 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 Security redeemed or to be redeemed only in part, to the
portion of the principal amount of such Security which has been or is to be
redeemed.

         SECTION 1104. NOTICE OF REDEMPTION.

         Except as otherwise specified as contemplated by Section 301, notice of
redemption shall be given in the manner provided for in Section 106 not less
than 30 nor more than 60 days prior to the Redemption Date, to each Holder of
Securities to be redeemed.

         All notices of redemption shall identify the Securities (including
CUSIP number, if any) to be redeemed and shall state:

         (1) the Redemption Date,

         (2) the Redemption Price and the amount of accrued interest to the
Redemption Date payable as provided in Section 1106, if any,

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

                                       66
<PAGE>   72

         (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 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 and accrued
interest, if any, to the Redemption Date payable as provided in Section 1106
will become due and payable upon each such Security, or the portion thereof, to
be redeemed and, if applicable, that interest thereon will cease to accrue on
and after said date,

         (6) the Place or Places of Payment 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 accrued interest, if any,

         (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 Redemption Date 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, and

         (9) if Bearer Securities of any series are to be redeemed and any
Registered Securities of such series are not to be redeemed, and if such Bearer
Securities may be exchanged for Registered Securities not subject to redemption
on such Redemption Date pursuant to Section 306 or otherwise, the last date, as
determined by the Company, on which such exchanges may be made.

         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 1105. DEPOSIT OF REDEMPTION PRICE.

         The Company shall deposit with the Trustee or with a Paying Agent (or,
if the Company is acting as its own Paying Agent, segregate and hold in trust as
provided in Section 1003) on or prior to the Redemption Date an amount of money
in the Currency in which the Securities of such series are payable (except as
otherwise specified pursuant to Section 301 for the Securities of such series
and except, if applicable, as provided in Sections 313(b), 313(d) and 313(e))
sufficient to pay the Redemption Price of, and accrued interest, if any, on, all
the Securities which are to be redeemed on that date.

         SECTION 1106. 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

                                       67
<PAGE>   73

specified in the Currency in which the Securities of such series are payable
(except as otherwise specified pursuant to Section 301 for the Securities of
such series and except, if applicable, as provided in Sections 313(b), 313(d)
and 313(e)) (together with accrued interest, if any, to the Redemption Date),
and from and after such date (unless the Company shall default in the payment of
the Redemption Price and accrued interest, if any) such Securities shall, if the
same were interest-bearing, 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 accrued interest, if
any, to the Redemption Date; provided, however, that installments of interest on
Bearer Securities whose Stated Maturity is on or prior to the Redemption Date
shall be payable only at an office or agency located outside the United States
(except as otherwise provided in Section 1002) and, unless otherwise specified
as contemplated by Section 301, only upon presentation and surrender of coupons
for such interest; and provided further that 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
relevant Record Dates according to their terms and the provisions of Section
308.

         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 interest represented by coupons shall be payable only at an office
or agency located outside the United States (except as otherwise provided in
Section 1002) and, unless otherwise specified as contemplated by Section 301,
only upon presentation and surrender of those coupons.

         If any Security called for redemption shall not be so paid upon
surrender thereof for redemption, the principal (and premium, if any) shall,
until paid, bear interest from the Redemption Date at the rate of interest or
Yield to Maturity (in the case of Original Issue Discount Securities) set forth
in such Security.

         SECTION 1107. SECURITIES REDEEMED IN PART.

         Any Security which is to be redeemed only in part (pursuant to the
provisions of this Article or of Article Twelve) shall be surrendered at a Place
of Payment therefor (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 such Holder's
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

                                       68
<PAGE>   74

Security or Securities of the same series, of any authorized denomination as
requested by such Holder, in aggregate principal amount equal to and in exchange
for the unredeemed portion of the principal of the Security so surrendered.

                                 ARTICLE TWELVE
                                  SINKING FUNDS

         SECTION 1201. APPLICABILITY OF ARTICLE.

         Retirements of Securities of any series pursuant to any sinking fund
shall be made in accordance with the terms of such Securities and (except as
otherwise specified as contemplated by Section 301 for Securities of any series)
in accordance with this Article.

         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 any 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 mandatory sinking fund payment may be subject to
reduction as provided in Section 1202. 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.

         SECTION 1202. SATISFACTION OF SINKING FUND PAYMENTS WITH SECURITIES.

         Subject to Section 1203, in lieu of making all or any part of any
mandatory sinking fund payment with respect to any Securities of a series in
cash, the Company may at its option (1) deliver to the Trustee Outstanding
Securities of a series (other than any previously called for redemption)
theretofore purchased or otherwise acquired by the Company together in the case
of any Bearer Securities of such series with all unmatured coupons appertaining
thereto, and/or (2) receive credit for the principal amount of Securities of
such series which have been previously delivered to the Trustee by the Company
or for Securities of such series which have been redeemed either at the election
of the Company pursuant to the terms of such Securities or through the
application of permitted optional sinking fund payments pursuant to the terms of
such Securities, in each case in satisfaction of all or any part of any
mandatory sinking fund payment with respect to the Securities of the same series
required to be made pursuant to the terms of such Securities as provided for by
the terms of such series; provided, however, that such 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
mandatory sinking fund payment shall be reduced accordingly.

         SECTION 1203. REDEMPTION OF SECURITIES FOR SINKING FUND.

         Not less than 60 days prior to each sinking fund payment date for any
series of Securities, the Company will deliver to the Trustee an Officers'
Certificate specifying the amount of the next

                                       69
<PAGE>   75

ensuing 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
in the Currency in which the Securities of such series are payable (except as
otherwise specified pursuant to Section 301 for the Securities of such series
and except, if applicable, as provided in Sections 313(b), 313(d) and 313(e))
and the portion thereof, if any, which is to be satisfied by delivering or
crediting Securities of that series pursuant to Section 1202 (which Securities
will, if not previously delivered, accompany such certificate) and whether the
Company intends to exercise its right to make a permitted optional sinking fund
payment with respect to such series. Such certificate shall be irrevocable and
upon its delivery the Company shall be obligated to make the cash payment or
payments therein referred to, if any, on or before the next succeeding sinking
fund payment date. In the case of the failure of the Company to deliver such
certificate, the sinking fund payment due on the next succeeding sinking fund
payment date for that series shall be paid entirely in cash and shall be
sufficient to redeem the principal amount of such Securities subject to a
mandatory sinking fund payment without the option to deliver or credit
Securities as provided in Section 1202 and without the right to make any
optional sinking fund payment, if any, with respect to such series.

         Not more 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 1103 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 1104. Such notice having been duly given, the
redemption of such Securities shall be made upon the terms and in the manner
stated in Sections 1106 and 1107.

         On or prior to any sinking fund payment date, the Company shall pay to
the Trustee or a Paying Agent (or, if the Company is acting as its own Paying
Agent, segregate and hold in trust as provided in Section 1003) in cash a sum
equal to any interest that will accrue to the date fixed for redemption of
Securities or portions thereof to be redeemed on such sinking fund payment date
pursuant to this Section 1203.

         Notwithstanding the foregoing, with respect to a sinking fund for any
series of Securities, if at any time the amount of cash to be paid into such
sinking fund on the next succeeding sinking fund payment date, together with any
unused balance of any preceding sinking fund payment or payments for such
series, does not exceed in the aggregate $100,000, the Trustee, unless requested
by the Company, shall not give the next succeeding notice of the redemption of
Securities of such series through the operation of the sinking fund. Any such
unused balance of moneys deposited in such sinking fund shall be added to the
sinking fund payment for such series to be made in cash on the next succeeding
sinking fund payment date or, at the written request of the Company, shall be
applied at any time or from time to time to the purchase of Securities of such
series, by public or private purchase, in the open market or otherwise, at a
purchase price for such Securities (excluding accrued interest and brokerage
commissions, for which the Trustee or any Paying Agent will be promptly
reimbursed by the Company) not in excess of the principal amount thereof.

                          PURCHASE AT OPTION OF HOLDERS

         SECTION 1301. APPLICABILITY OF ARTICLE.

         Purchase by the Company of Securities of any series before their Stated
Maturity at the option of Holders thereof shall be made in accordance with the
terms of such Securities and (except as otherwise specified as contemplated by
Section 301 for Securities of any series) in accordance with this Article.

         SECTION 1302. PURCHASE OF SECURITIES.

         Securities of any series subject to purchase in whole or in part at the
option of the Holders thereof will, unless otherwise provided in the terms of
such Securities, be purchased at a price equal to the principal amount thereof,
together with interest, if any, thereon accrued to the Purchase Date specified
in or pursuant to the terms of such Securities. The Company covenants that on or
before the Purchase Date it will deposit with the Trustee or with a Paying Agent
(or, if the Company is acting as its own Paying Agent, segregate and hold in
trust as provided in Section 1003) an amount of money in the Currency in which
the Securities of such series are payable (except as otherwise specified
pursuant to Section 301 for the Securities of such series and except, if
applicable, as provided in Sections 313(b), 313(d) and 313(e)) sufficient to pay
the principal (or, if so provided by the terms of the Securities of any series,
a percentage of the principal) of and (except if the Purchase Date shall be an
Interest Payment Date) accrued interest, if any, on, all the Securities or
portions thereof, as the case may be, to be purchased on such date.

         SECTION 1303. EXERCISE OF OPTION.

         Securities of any series subject to purchase at the option of the
Holders thereof will contain an "Option to Elect Purchase" form on the reverse
of such Securities. To be purchased at the option of the Holder, any Security so
providing for such purchase, with the "Option to Elect Purchase" form on the
reverse of such Security duly completed by the Holder (or by the Holder's
attorney duly authorized in writing), must be received by the Company at the
Place of Payment therefor specified in the terms of such Security (or at such
other place or places of which the Company shall from time to time notify the
Holders of such Securities) not earlier than 45 days nor later than 30 days
prior to the Purchase Date. If less than the entire principal amount of such
Security is to be purchased in accordance with the terms of such Security, the
principal amount of such Security to be purchased, in increments of the minimum
denomination for Securities of such series, and the denomination or
denominations of the Security or Securities to be issued to the Holder for the
portion of the principal amount of such Security surrendered that is not to be
purchased, must be specified. The principal amount of any Security providing for
purchase at the option of the Holder thereof may not be purchased in part if,
following such purchase, the unpaid principal amount of such Security would be
less than the minimum authorized denomination of Securities of the series of
which such Security to be purchased is a part. Except as otherwise may be
provided by the terms of any Security providing for purchase at the option of
the Holder thereof, exercise of the purchase option by the Holder shall be
irrevocable unless waived by the Company.

                                       71
<PAGE>   77

         SECTION 1304. WHEN SECURITIES PRESENTED FOR PURCHASE BECOME DUE AND
PAYABLE.

         If Securities of any series providing for purchase at the option of the
Holders thereof shall have been surrendered as provided in this Article and as
provided by or pursuant to the terms of such Securities, such Securities or the
portions thereof, as the case may be, to be purchased shall become due and
payable and shall be paid by the Company on the Purchase Date therein specified,
and on and after such Purchase Date (unless the Company shall default in the
payment of such Securities on such Purchase Date) such Securities shall, if the
same were interest-bearing, cease to bear interest and the coupons for such
interest appertaining to any Bearer Securities so to be purchased, except to the
extent provided below, shall be void. Upon surrender of any such Security for
purchase in accordance with such provisions, together with all coupons, if any,
appertaining thereto maturing after the Purchase Date, the principal amount of
such Security so to be purchased shall be paid by the Company, together with
accrued interest, if any, to the Purchase Date; provided however, that coupons
whose Stated Maturity is on or prior to the Purchase Date shall be payable only
at an office or agency located outside the United States (except as otherwise
provided in Section 1002) and, unless otherwise specified pursuant to Section
301, only upon presentation and surrender of such coupons; and provided further
that, in the case of Registered Securities, installments of interest, if any,
whose Stated Maturity is on or prior to the Purchase Date shall be payable to
the Holders of such Securities, or one or more Predecessor Securities,
registered as such at the close of business on the relevant Record Dates
according to their terms and the provisions of Section 308.

         If any Bearer Security surrendered for purchase shall not be
accompanied by all appurtenant coupons maturing after the Purchase Date, such
Security may be paid after deducting from the amount payable therefor as
provided in Section 1302 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 amid 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 as provided in the preceding sentence, such Holder shall be entitled
to receive the amount so deducted; provided, however, that interest represented
by coupons shall be payable only at an office or agency located outside the
United States (except as otherwise provided in Section 1002) and, unless
otherwise specified as contemplated by Section 301, only upon presentation and
surrender of those coupons.

         If the principal amount of any Security surrendered for purchase shall
not be so purchased upon surrender thereof, such principal amount (together with
interest, if any, thereon accrued to such Purchase Date) shall, until paid, bear
interest from the Purchase Date at the rate of interest or Yield to Maturity (in
the case of Original Issue Discount Securities) set forth in such Security.

         SECTION 1305. SECURITIES PURCHASED IN PART.

         Upon surrender of any Registered Security which is to be purchased in
part only, the Company shall execute and the Trustee shall authenticate and
deliver to the Holder of such Security, without service charge and at the
expense of the Company, a new Registered Security or Securities of the same
series, of any authorized denomination specified by the Holder, in an aggregate
principal amount equal to and in exchange for the portion of the principal of
such Security so surrendered which is not to be purchased.

                                ARTICLE FOURTEEN
                       DEFEASANCE AND COVENANT DEFEASANCE

         SECTION 1401. COMPANY'S OPTION TO EFFECT DEFEASANCE OR COVENANT
DEFEASANCE.

         Except as otherwise specified as contemplated by Section 301 for
Securities of any series, the provisions of this Article Fourteen shall apply to
each series of Securities, and the Company may, at its option, effect defeasance
of the Securities of or within a series under Section 1402, or covenant
defeasance of or within a series under Section 1403 in accordance with the terms
of such Securities and in accordance with this Article.

         SECTION 1402. DEFEASANCE AND DISCHARGE.

         Upon the Company's exercise of the above option applicable to this
Section 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 related coupons on the date the conditions set
forth in Section 1404 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 related coupons, which shall thereafter be deemed to be "Outstanding"
only for the purposes of Section 1405 and the other Sections of this Indenture
referred to in (A) and (B) below, and to have satisfied all its other
obligations under such Securities and any related coupons and this Indenture
insofar as such Securities and any related coupons 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: (A) the rights of Holders of such
Outstanding Securities and any related coupons to receive, solely from the trust
fund described in Section 1404 and as more fully set forth in such Section,
payments in respect of the principal of (and premium, if any) and interest, if
any, on such Securities and any related coupons when such payments are due, (B)
the Company's obligations with respect to such Securities under Sections 304,
305, 306, 1002 and 1003, (C) the rights, powers, trusts, duties and immunities
of the Trustee hereunder and (D) this Article Fourteen. Subject to compliance
with this Article Fourteen, the Company may exercise its option under this
Section 1402 notwithstanding the prior exercise of its option under Section 1403
with respect to such Securities and any related coupons.

                                       73
<PAGE>   79

         SECTION 1403. COVENANT DEFEASANCE.

         Upon the Company's exercise under Section 1401 of the option applicable
to this Section 1403 with respect to any Securities of or within a series, the
Company shall be released from its obligations under any covenant under Article
Eight and in Sections 1004 through 1008, and, if specified pursuant to Section
301, its obligations under any other covenant, with respect to such Outstanding
Securities and any related coupons on and after the date the conditions set
forth in Section 1404 are satisfied (hereinafter, "Covenant Defeasance"), and
such Securities and any related coupons 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 such
covenants, but shall continue to be deemed "Outstanding" for all other purposes
hereunder (it being understood that such Securities shall not be deemed
Outstanding for financial accounting purposes). For this purpose, such covenant
defeasance means that, with respect to such Outstanding Securities and any
related coupons, 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 covenant,
whether directly or indirectly, by reason of any reference elsewhere herein to
any such covenant or by reason of reference in any such 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 501(4) or Section
501(9) or otherwise, as the case may be, but, except as specified above, the
remainder of this Indenture and such Securities and any related coupons shall be
unaffected thereby. In addition, upon the Company's exercise under Section 1401
of the option applicable to Section 1403, Sections 501(4) through 501(6) shall
not constitute Events of Default.

         SECTION 1404. CONDITIONS TO DEFEASANCE OR COVENANT DEFEASANCE.

         The following shall be the conditions to application of either Section
1402 or Section 1403 to any Outstanding Securities of or within a series and any
related coupons:

         (1) The Company shall irrevocably have deposited or caused to be
deposited with the Trustee (or another trustee satisfying the requirements of
Section 607 who shall agree to comply with the provisions of this Article
Fourteen 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 related coupons, (A)
money (in Dollars or in the Foreign Currency in which the applicable series of
Securities is payable) in an amount, or (B) Government Obligations applicable to
such Securities 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, under such Securities and any related coupons, money (in
Dollars or in the Foreign Currency in which the applicable series of Securities
is payable) in an amount, or (C) a combination thereof, sufficient, in the
opinion of a nationally recognized firm of independent public accountants
expressed in a written certification thereof delivered to the Trustee, to pay
and discharge, and which shall be applied by the Trustee (or other qualifying
trustee) to pay and discharge, (i) the principal of (and premium, if any) and
interest, if any, on such Outstanding Securities and any related coupons on the
Stated Maturity (or Redemption Date, if applicable) of such principal (and
premium, if any) or installment of interest, if any, and (ii) any mandatory

                                       74
<PAGE>   80

sinking fund payments or analogous payments applicable to such Outstanding
Securities and any related coupons on the day on which such payments are due and
payable in accordance with the terms of this Indenture and of such Securities
and any related coupons; provided that the Trustee shall have been irrevocably
instructed to apply such money or the proceeds of such Government Obligations to
said payments with respect to such Securities and any related coupons. Before
such a deposit, the Company may give to the Trustee, in accordance with Section
1102 hereof, a notice of its election to redeem all or any portion of such
Outstanding Securities at a future date in accordance with the terms of the
Securities of such series and Article Eleven hereof, which notice shall be
irrevocable. Such irrevocable redemption notice, if given, shall be given effect
in applying the foregoing.

         (2) No Default or Event of Default with respect to such Securities
or any related coupons shall have occurred and be continuing on the date of such
deposit or, insofar as paragraphs (7) and (8) of Section 501 are concerned, at
any time during the period ending on the 91st day after the date of such deposit
(it being understood that this condition shall not be deemed satisfied until the
expiration of such period).

         (3) No event or condition shall exist that would prevent the
Company from making payments of the principal of (and premium, if any) or
interest on the Securities on the date of such deposit or at any time during the
period ending on the 91st day after the date of such deposit (it being
understood that this condition shall not be deemed satisfied until the
expiration of such period).

         (4) 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 or cause the Trustee or the trust so created to be subject to
the Investment Company Act of 1940, as amended.

         (5) In the case of an election under Section 1402, the Company
shall have delivered to the Trustee an Opinion of Counsel stating that (x) the
Company has received from, or there has been published by, the Internal Revenue
Service a ruling, or (y) 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 related coupons 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.

         (6) In the case of an election under Section 1403, the Company
shall have delivered to the Trustee an Opinion of Counsel to the effect that the
Holders of such Outstanding Securities and any related coupons 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.

                                       75
<PAGE>   81

         (7) In the case of an election under either Section 1402 or 1403,
the Company shall represent to the Trustee that the deposit made by the Company
pursuant to its election under Section 1402 or 1403 was not made by the Company
with the intent of preferring the Holders of Securities of any series over other
creditors of the Company or with the intent of defeating, hindering, delaying or
defrauding creditors of the Company or others.

         (8) Notwithstanding any other provisions of this Section, such
defeasance or covenant defeasance shall be effected in compliance with any
additional or substitute terms, conditions or limitations in connection
therewith pursuant to Section 301.

         (9) The Company shall have delivered to the Trustee an Officers'
Certificate and an Opinion of Counsel, each stating that all conditions
precedent provided for relating to either the defeasance under Section 1402 or
the covenant defeasance under Section 1403 (as the case may be) have been
complied with.

         SECTION 1405. DEPOSITED MONEY AND GOVERNMENT OBLIGATIONS TO BE HELD IN
TRUST; OTHER MISCELLANEOUS PROVISIONS.

         Subject to the provisions of the last paragraph of Section 1003, all
money and Government Obligations (or other property as may be provided pursuant
to Section 301) (including the proceeds thereof) deposited with the Trustee (or
other qualifying trustee, collectively for purposes of this Section 1405, the
"Trustee") pursuant to Section 1404 in respect of such Outstanding Securities
and any related coupons shall be held in trust and applied by the Trustee, in
accordance with the provisions of such Securities and any related coupons 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 related coupons of all sums
due and to become due thereon in respect of principal (and premium, if any) and
interest, if any, but such money need not be segregated from other funds except
to the extent required by law.

         Unless otherwise specified with respect to any Security pursuant to
Section 301, if, after a deposit referred to in Section 1404(1) 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 313(b) or the terms of such
Security to receive payment in a Currency other than that in which the deposit
pursuant to Section 1404(1) has been made in respect of such Security, or (b) a
Conversion Event occurs as contemplated in Section 313(d) or 313(e) or by the
terms of any Security in respect of which the deposit pursuant to Section
1404(1) has been made, the indebtedness represented by such Security and any
related coupons 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 such Security as they become 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 the applicable Market Exchange Rate
for such Currency in effect on the third Business Day prior to each payment
date, except, with respect to a Conversion Event, for such Currency in effect
(as nearly as feasible) at the time of the Conversion Event.

                                       76
<PAGE>   82

         The Company shall pay and indemnify the Trustee against any tax, fee or
other charge imposed on or assessed against the Government Obligations deposited
pursuant to Section 1404 or the principal and 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 related coupons.

         Anything in this Article Fourteen 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 Section 1404 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 an
equivalent defeasance or covenant defeasance, as applicable, in accordance with
this Article.

         SECTION 1406. REINSTATEMENT.

         If the Trustee or any Paying Agent is unable to apply any money in
accordance with Section 1405 by reason of any order or judgment of any court or
governmental authority enjoining, restraining or otherwise prohibiting such
application, then the Company's obligations under this Indenture and such
Securities and any related coupons shall be revived and reinstated as though no
deposit had occurred pursuant to Section 1402 or 1403, as the case may be, until
such time as the Trustee or Paying Agent is permitted to apply all such money in
accordance with Section 1405; provided, however, that if the Company makes any
payment of principal of (or premium, if any) or interest, if any, on any such
Security or any related coupon following the reinstatement of its obligations,
the Company shall be subrogated to the rights of the Holders of such Securities
and any related coupons to receive such payment from the money held by the
Trustee or Paying Agent.

                                 ARTICLE FIFTEEN
                        MEETINGS OF HOLDERS OF SECURITIES

         SECTION 1501. PURPOSES FOR WHICH MEETINGS MAY BE CALLED.

         If Securities of a series are issuable as Bearer Securities, a meeting
of Holders of Securities of such series may be called at any time and from time

<PAGE>   83

Securities of any series, setting forth the time and the place of such meeting
and in general terms the action proposed to be taken at such meeting, shall be
given, in the manner provided for in Section 106, not less than 21 nor more than

Outstanding Securities of any series shall have requested the Trustee to call a
meeting of the Holders of Securities of such series for any purpose specified in
Section 1501, by written request setting forth in reasonable detail the action
proposed to be taken at the meeting, and the Trustee shall not have made the
first publication of the notice of such meeting within 21 days after receipt of
such request or shall not thereafter proceed to cause the meeting to be held as
provided herein, then the Company or the Holders of Securities of such series in
the amount above specified, as the case may be, may determine the time and the
place in The City of New York or [IN LONDON] for such meeting and may call such
meeting for such purposes by giving notice thereof as provided in paragraph (a)
of this Section.

         SECTION 1503. PERSONS ENTITLED TO VOTE AT MEETINGS.

         To be entitled to vote at any meeting of Holders of Securities of any
series, a Person shall be (1) a Holder of one or more Outstanding Securities of
such series, or (2) a Person appointed by an instrument in writing as proxy for
a Holder or Holders of one or more Outstanding Securities of such series by such

         SECTION 1504. QUORUM; ACTION.

         The Persons entitled to vote a majority in principal amount of the

series, the Persons entitled to vote such specified percentage in principal
amount of the Outstanding Securities of such series shall constitute a quorum.
In the absence of a quorum within 30 minutes of the time appointed for any such
meeting, the meeting shall, if convened at the request of Holders of Securities
of such series, be dissolved. In any other case the meeting may be adjourned for

prior to the adjournment of such meeting. In the absence of a quorum at any such
adjourned meeting, such adjourned meeting may be further adjourned for a period
of not less than 10 days as determined by the chairman of the meeting prior to
the adjournment of such adjourned meeting. Notice of the reconvening of any
adjourned meeting shall be given as provided in Section 1502(a), except that

                                       78
<PAGE>   84

         Subject to the foregoing, at the reconvening of any meeting adjourned
for lack of a quorum the Persons entitled to vote 25% in principal amount of the
Outstanding Securities at the time shall constitute a quorum for the taking of
any action set forth in the notice of the original meeting.

         Except as limited by the proviso to Section 902, any resolution
presented to a meeting or adjourned meeting duly reconvened at which a quorum is
present as aforesaid may be adopted by the affirmative vote of the Holders of
not less than a majority in principal amount of the Outstanding Securities of
such series; provided however, that, except as limited by the proviso to Section
902, any resolution with respect to any request, demand, authorization,
direction, notice, consent, waiver or other action which this Indenture
expressly provides may be made, given or taken by the Holders of a specified
percentage, which is less than a majority, in principal amount of the
Outstanding Securities of a series may be adopted at a meeting or an adjourned
meeting duly reconvened and at which a quorum is present as aforesaid by the
affirmative vote of the Holders of not less than such specified percentage in
principal amount of the Outstanding Securities of such series.

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

         Notwithstanding the foregoing provisions of this Section 1504, if any
action is to be taken at a meeting of Holders of Securities of any series with
respect to any request, demand, authorization, direction, notice, consent,
waiver or other action that this Indenture expressly provides may be made, given
or taken by the Holders of a specified percentage in principal amount of all
Outstanding Securities affected thereby, or of the Holders of such series and
one or more additional series:

         (i) there shall be no minimum quorum requirement for such meeting; and

         (ii) the principal amount of the Outstanding Securities of such
series that vote in favor of such request, demand, authorization, direction,
notice, consent, waiver or other action shall be taken into account in
determining whether such request, demand, authorization, direction, notice,
consent, waiver or other action has been made, given or taken under this
Indenture.

         SECTION 1505. DETERMINATION OF VOTING RIGHTS; CONDUCT AND ADJOURNMENT
OF MEETINGS.

         (a) Notwithstanding any provisions of this Indenture, the Trustee
may make such reasonable regulations as it may deem advisable for any meeting of
Holders of Securities of a series in regard to proof of the holding of
Securities of such series and of the appointment of proxies and in regard to the
appointment and duties of inspectors of votes, the submission and examination of
proxies, certificates and other evidence of the right to vote, and such other
matters concerning the conduct of the meeting as it shall deem appropriate.
Except as otherwise permitted or required by any such regulations, the holding
of Securities shall be proved in the manner

                                       79
<PAGE>   85

specified in Section 104 and the appointment of any proxy shall be proved in the
manner specified in Section 104 or by having the signature of the person
executing the proxy witnessed or guaranteed by any trust company, bank or banker
authorized by Section 104 to certify to the holding of Bearer Securities. Such
regulations may provide that written instruments appointing proxies, regular on
their face, may be presumed valid and genuine without the proof specified in
Section 104 or other proof.

         (b) 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 1502(b), in which
case the Company or the Holders of Securities of the series calling the meeting,
as the case may be, shall in like manner appoint a temporary chairman. A
permanent chairman and a permanent secretary of the meeting shall be elected by
vote of the Persons entitled to vote a majority in principal amount of the
Outstanding Securities of such series represented at the meeting.

         (c) At any meeting each Holder of a Security of such series or
proxy shall be entitled to one vote for each $1,000 principal amount of
Outstanding Securities of such series held or represented by him (determined as
specified in the definition of "Outstanding" in Section 101); provided, however,
that no vote shall be cast or counted at any meeting in respect of any Security
challenged as not Outstanding and ruled by the chairman of the meeting to be not
Outstanding. The chairman of the meeting shall have no right to vote, except as
a Holder of a Security of such series or proxy.

         (d) Any meeting of Holders of Securities of any series duly called
pursuant to Section 1502 at which a quorum is present may be adjourned from time
to time by Persons entitled to vote a majority in principal amount of the
Outstanding Securities of such series represented at the meeting; and the
meeting may be held as so adjourned without further notice.

         SECTION 1506. COUNTING VOTES AND RECORDING ACTION OF MEETINGS.

         The vote upon any resolution submitted to any meeting of Holders of
Securities of any series shall be by written ballots on which shall be
subscribed the signatures of the Holders of Securities of such series or of
their representatives by proxy and the principal amounts and serial numbers of
the Outstanding Securities of such series held or represented by them. The
permanent chairman of the meeting shall appoint two inspectors of votes who
shall count all votes cast at the meeting for or against any resolution and who
shall make and file with the secretary of the meeting their verified written
reports in duplicate of all votes cast at the meeting. A record, at least in
duplicate, of the proceedings of each meeting of Holders of Securities of any
series shall be prepared by the Secretary of the meeting and there shall be
attached to said record the original reports of the inspectors of votes on any
vote by ballot taken thereat and affidavits by one or more persons having
knowledge of the facts setting forth a copy of the notice of the meeting and
showing that said notice was given as provided in Section 1502 and, if
applicable, Section 1504. Each copy shall be signed and verified by the
affidavits of the permanent chairman and secretary of the meeting and one such
copy shall be delivered to the Company, and another to the Trustee to be
preserved by the Trustee, the latter to have attached thereto the ballots voted
at the meeting. Any record so signed and verified shall be conclusive evidence
of the matters therein stated.

such Person may certify or give an opinion with respect to some matters and one

insofar as it relates to legal matters, upon a certificate or opinion of, or
representations by, counsel, unless such officer knows, or in the exercise of
reasonable care should know, that the certificate or opinion or representations

SECTION 104. ACTS OF HOLDERS.

         (a) Any request, demand, authorization, direction, notice,
consent, waiver or other action provided by this Indenture to be given or taken
by Holders of the Outstanding Securities of all series or one or more series, as
the case may be, may be embodied in and evidenced by one or more instruments of
substantially similar tenor signed by such Holders in person or by agents duly
appointed in writing. If Securities of a series are issuable as Bearer
Securities, any request, demand, authorization, direction, notice, consent,
waiver or other action provided by this Indenture to be given or taken by
Holders 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 Fifteen, 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 TIA Section 315) conclusive in
favor of the Trustee and the Company, if made in the manner provided in this
Section. The record of any meeting of Holders of Securities shall be proved in
the manner provided in Section 1506.

         (b) The fact and date of the execution by any Person of any such
instrument or writing may be proved in any reasonable manner which the Trustee
deems sufficient.

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

         (d) The principal amount and serial numbers of Bearer Securities
held by any Person, and the date 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, wherever
situated, if such certificate shall be deemed by 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 (1) another certificate or affidavit bearing
a later date issued in respect of the same Bearer Security is produced, or (2)
such Bearer Security is produced to the Trustee by some other Person, or (3)
such Bearer Security is surrendered in exchange for a Registered Security, or
(4) such Bearer Security is no longer Outstanding. The principal amount and
serial numbers of Bearer Securities held by any Person, and the date of holding
the same, may also be proved in any other manner that the Trustee deems
sufficient.

         (e) If the Company shall solicit from the Holders of Registered
Securities any request, demand, authorization, direction, notice, consent,
waiver or other Act, the Company may, at its option, by or pursuant to a Board
Resolution, fix in advance a record date for the

                                       15
<PAGE>   21

determination of such Holders entitled to give such request, demand,
authorization, direction, notice, consent, waiver or other Act, but the Company
shall have no obligation to do so. Notwithstanding TIA Section 316(c), any such
record date shall be the record date specified in or pursuant to such Board
Resolution, which shall be a date not more than 30 days prior to the first
solicitation of Holders generally in connection therewith and no later than the
date such solicitation is completed. 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 record at
the close of business on such record date shall be deemed to be Holders for the
purposes of determining whether Holders of the requisite proportion of
Securities then Outstanding have authorized or agreed or consented to such
request, demand, authorization, direction, notice, consent, waiver or other Act,
and for that purpose the Securities then Outstanding shall be computed as of
such record date, provided that no such request, demand, authorization,
direction, notice, consent, waiver or other Act by the Holders on such record
date 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.

         (f) 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 or 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, suffered or omitted to be done by the Trustee, any
Paying Agent or the Company in reliance thereon, whether or not notation of such
action is made upon such Security.

SECTION 105. NOTICES, ETC., TO TRUSTEE AND COMPANY.

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

         (1) the Trustee by any Holder or the Company shall be sufficient for
every purpose hereunder if made, given, furnished or delivered, in writing, to
or with the Trustee at its Corporate Trust Office, Attention: Corporate Trust
Administration; or

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

SECTION 106. NOTICE TO HOLDERS; WAIVER.

         Where this Indenture provides for notice of any event to Holders of
Registered Securities by the Company or the Trustee, such notice shall be
sufficiently given (unless otherwise herein expressly provided) if in writing
and mailed, first-class postage prepaid, to each Holder affected by such event,
at his address as it appears in the Security Register, not later than the latest
date,

                                       16
<PAGE>   22

and not earlier than the earliest 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 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. Any notice mailed to a
Holder in the aforesaid manner shall be conclusively deemed to have been
received by such Holder, whether or not such Holder actually receives such
notice.

         In case, by reason of the suspension of or irregularities in regular
mail service or by reason of any other cause, it shall be impractical to mail
notice of any event to Holders of Registered Securities when such notice is
required to be given pursuant to any provision of this Indenture, then any
manner of giving such notice as shall be satisfactory to the Trustee shall be
deemed to be sufficient giving of such notice for every purpose hereunder.

         Except as otherwise expressly provided herein or otherwise specified
with respect to any Securities pursuant to Section 301, where this Indenture
provides for notice to Holders of Bearer Securities of any event, such notice
shall be sufficiently given to Holders of Bearer Securities if published in an
Authorized Newspaper in The City of New York and in such other city or cities as
may be specified in such Securities on a Business Day at least twice, the first
such publication to be not earlier than the earliest date, and not later than
the latest date, prescribed for the giving of such notice. Any such notice shall
be deemed to have been given on the date of the first such publication.

         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 the 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 such notice with
respect to other Holders of Bearer Securities or the sufficiency of any notice
to Holders of Registered Securities given as provided herein.

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

         Where this Indenture provides for notice in any manner, such notice may
be waived in writing by the Person entitled to receive such notice, either
before or after the event, and such waiver shall be the equivalent of such
notice. Waivers of notice by Holders shall be filed with the Trustee, but such
filing shall not be a condition precedent to the validity of any action taken in
reliance upon such waiver.

qualifies or conflicts with the duties imposed by TIA Sections 310 to 318,
inclusive, or conflicts with any provision (an "incorporated provision")
required by or deemed to be included in this Indenture by operation of such TIA
Sections, such imposed duties or incorporated provision shall control. If any
provision of this Indenture modifies or excludes any provision of the Trust
Indenture Act that may be so modified or excluded, the latter provision shall be
deemed to apply to this Indenture as so modified or excluded, as the case may
be.

impaired thereby.

SECTION 111. BENEFITS OF INDENTURE.

implied, shall give to any Person, other than the parties hereto, any
Authenticating Agent, any Paying Agent, any Securities Registrar, any holders of
Senior Indebtedness and their successors hereunder and the Holders of Securities
or coupons, any benefit or any legal or equitable right, remedy or claim under
this Indenture.

SECTION 113. LEGAL HOLIDAYS.

         In any case where any Interest Payment Date, Redemption Date, sinking
fund payment date or Stated Maturity or Maturity of any Security shall not be a
Business Day at any Place of Payment, then (notwithstanding any other provision
of this Indenture or of any Security or coupon other than a provision in the
Securities of any series which specifically states that such provision shall
apply in lieu of this Section), payment of principal (or premium, if any) or
interest, if any, need not be made at such Place of Payment on such date, but
may be made on the next succeeding Business Day at such Place of Payment with
the same force and effect as if made on the Interest Payment Date or Redemption
Date or sinking fund payment date, or at the Stated Maturity or Maturity;
provided that no interest shall accrue for the period from and after such

of the Company shall have any liability for any obligations of the Company under
the Securities or this Indenture or for any claim based on, in respect of, or by
reason of, such obligations or their creations. Each Holder by accepting any of
the Securities waives and releases all such liability. Such waiver and release
are part of the consideration for the issuance of the Securities of any series.

SECTION 203. SECURITIES ISSUABLE IN GLOBAL FORM.

         If Securities of or within a series are issuable in global form, as
specified as contemplated by Section 301, then, any such Security shall
represent such of the Outstanding Securities of such series as shall be
specified therein and may provide that it shall represent the aggregate amount
of Outstanding Securities of such series from time to time endorsed thereon and
that the aggregate amount of Outstanding Securities of such series represented
thereby may from time to time be increased or decreased to reflect exchanges.
Any endorsement of a Security in global form to reflect the amount, or any
increase or decrease in the amount, of Outstanding Securities represented
thereby shall be made by the Trustee in such manner and upon instructions given
by such Person or Persons as shall be specified therein or in the Company Order
to be delivered to the Trustee pursuant to Section 303 or Section 305. Subject
to the provisions of Section 303 and, if applicable, Section 305, the Trustee
shall deliver and redeliver 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 303 or Section
305 has been, or simultaneously is, delivered, any instructions by the Company
with respect to

<PAGE>   26

endorsement or delivery or redelivery of a Security in global form shall be in
writing but need not comply with Section 102 and need not be accompanied by an
Opinion of Counsel.

         The provisions of the last sentence of Section 303 shall apply to any
Security represented by a Security in global form if such Security was never
issued and sold by the Company and the Company delivers to the Trustee the
Security in global form together with written instructions (which need not
comply with Section 102 and need not be accompanied by an Opinion of Counsel)
with regard to the reduction in the principal amount of Securities represented
thereby, together with the written statement contemplated by the last sentence
of Section 303.

         Notwithstanding the provisions of Section 308, unless otherwise
specified as contemplated by Section 301, payment of principal of (and premium,
if any) and interest, if any, on any Security in permanent global form shall be
made to the Person or Persons specified therein.

         Notwithstanding the provisions of Section 310 and except as provided in
the preceding paragraph, the Company, the Trustee and any agent of the Company
and the Trustee shall treat as the Holder of such principal amount of
Outstanding Securities represented by a permanent Global Security (i) in the
case of a permanent Global Security in registered form, the Holder of such
permanent Global Security in registered form, or (ii) in the case of a permanent
Global Security in bearer form, Euroclear or Cedel.

SECTION 204. FORM OF LEGEND FOR BOOK-ENTRY SECURITIES.

         Any Global Security authenticated and delivered hereunder shall bear a

a Restricted Security) in substantially the following form:

         THIS SECURITY IS A GLOBAL SECURITY WITHIN THE MEANING OF THE INDENTURE
HEREINAFTER REFERRED TO AND IS REGISTERED IN THE NAME OF A DEPOSITORY OR A

case of Registered Securities, as to denomination and except as may otherwise be
provided in or pursuant to such Board Resolution (subject to Section 303) and
set forth in such Officers' Certificate or in any such indenture supplemental
hereto. Not all Securities of any one series need be issued at the same time,
and, unless otherwise provided, a series may be reopened for issuances of
additional Securities of such series.

<PAGE>   30

SECTION 302. DENOMINATIONS.

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

SECTION 303. EXECUTION, AUTHENTICATION, DELIVERY AND DATING.

         The Securities and any coupons appertaining thereto shall be executed
on behalf of the Company by any one of the following: its Chairman, Chief
Executive Officer, its President or one of its Vice Presidents, and attested by
one of its Vice Presidents or its Secretary or one of its Assistant Secretaries.
The signature of any of these officers on the Securities or coupons may be
manual or facsimile.

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

         At any time and from time to time after the execution and delivery of
this Indenture, the Company may deliver Securities of any series together with
any coupon appertaining thereto, executed by the Company to the Trustee for
authentication, together with a Company Order for the authentication and
delivery of such Securities, and the Trustee in accordance with such Company
Order shall authenticate and make available for delivery such Securities;
provided, however, that, in connection with its original issuance, no Bearer
Security shall be mailed or otherwise delivered to any location in the United
States: and provided further that, unless otherwise specified with respect to
any series of Securities pursuant to Section 301, a Bearer Security may be
delivered in connection with its original issuance only if the Person entitled
to receive such Bearer Security shall have furnished a certificate in the form
set forth in EXHIBIT A-1 to this Indenture, dated no earlier than 15 days prior
to the earlier of the date on which such Bearer Security is delivered and the
date on which any temporary Security first becomes exchangeable for such Bearer
Security in accordance with the terms of such temporary Security and this
Indenture. If any Security shall be represented by a permanent global Bearer
Security, then, for purposes of this Section and Section 305, the notation of a
beneficial owner's interest therein upon original issuance of such Security or
upon exchange of a portion of a temporary Global Security shall be deemed to be
delivery in connection with its original issuance of such beneficial owner's
interest in such permanent Global Security. Except as permitted by Section 307,
the Trustee shall not authenticate and make available for delivery any Bearer
Security unless all appurtenant coupons for interest then matured have been
detached and canceled. If not all the Securities of any series are to be issued
at one time and if the Board Resolution or supplemental indenture establishing
such series shall so permit, such Company Order may set forth procedures
acceptable to the Trustee for the issuance of such Securities and determining

                                       25
<PAGE>   31

terms of particular Securities of such series such as interest rate, stated
maturity, date of issuance and date from which interest shall accrue.

         In authenticating such Securities, and accepting the additional
responsibilities under this Indenture in relation to such Securities, the
Trustee shall be entitled to receive, and (subject to TIA sections 315(a)
through 315(d)) shall be fully protected in relying upon, an Opinion of Counsel
stating:

         (a) that the form or forms of such Securities and any coupons have
been established in conformity with the provisions of this Indenture:

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

         (c) that such Securities, together with any coupons appertaining
thereto, when completed by appropriate insertions and executed and delivered by
the Company to the Trustee for authentication in accordance with this Indenture,
authenticated and made available for delivery by the Trustee in accordance with
this Indenture and issued by the Company in the manner and subject to any
conditions specified in such Opinion of Counsel, will constitute the legal,
valid and binding obligations of the Company, enforceable in accordance with
their terms, subject to applicable bankruptcy, insolvency, reorganization and
other similar laws of general applicability relating to or affecting the
enforcement of creditors' rights, to general equitable principles and to such
other qualifications as such counsel shall conclude do not materially affect the
rights of Holders of such Securities and any coupons;

         (d) that all laws and requirements in respect of the execution and
delivery by the Company of such Securities, any coupons and of the supplemental
indentures, if any, have been complied with and that authentication and delivery
of such Securities and any coupons and the execution and delivery of the
supplemental indenture, if any, by the Trustee will not violate the terms of the
Indenture;

         (e) that the Company has the corporate power to issue such Securities
and any coupons, and has duly taken all necessary corporate action with respect
to such issuance; and

         (f) that the issuance of such Securities and any coupons will not
contravene the articles of incorporation or by-laws of the Company or result in
any violation of any of the terms or provisions of any law or regulation or of
any indenture, mortgage or other agreement known to such Counsel by which the
Company is bound.

         Notwithstanding the provisions of Section 301 and of the preceding two
paragraphs, if not all the Securities of any series are to be issued at one
time, it shall not be necessary to deliver the Officers' Certificate otherwise
required pursuant to Section 301 or the Company Order and Opinion of Counsel
otherwise required pursuant to the preceding two paragraphs prior to or at the
time of issuance of each Security, but such documents shall be delivered prior
to or at the time of issuance of the first Security of such series.

                                       26
<PAGE>   32

         The Trustee shall not be required to authenticate and make available
for delivery any such Securities if the issue of such Securities pursuant to
this Indenture will affect the Trustee's own rights, duties or immunities under
the Securities and this Indenture or otherwise in a manner which is not
reasonably acceptable to the Trustee.

         Each Registered Security shall be dated the date of its authentication
and each Bearer Security shall be dated as of the date specified as contemplated
by Section 301.

         No Security or coupon shall be entitled to any benefit under this
Indenture or be valid or obligatory for any purpose unless there appears on such
Security a certificate of authentication substantially in the form provided for
herein duly executed by the Trustee by manual signature of an authorized
signatory, and such certificate upon any Security shall be conclusive evidence,
and the only evidence, that such Security has been duly authenticated and
delivered hereunder and is entitled to the benefits of this Indenture.
Notwithstanding the foregoing, if any Security shall have been authenticated and
delivered hereunder but never issued and sold by the Company, and the Company
shall deliver such Security to the Trustee for cancellation as provided in
Section 311 together with a written statement (which need not comply with
Section 102 and need not be accompanied by an Opinion of Counsel) stating that
such Security has never been issued and sold by the Company, for all purposes of
this Indenture such Security shall be deemed never to have been authenticated
and delivered hereunder and shall never be entitled to the benefits of this
Indenture.

SECTION 304. BOOK-ENTRY SECURITIES.

         (a) The Securities of a series may be issuable in whole or in part
in the form of one or more Global Securities ("Book-Entry Securities") deposited
with, or on behalf of, a Depository (the "Depository"). In the case of
Book-Entry Securities, one or more Global Securities will be issued in a
denomination or aggregate denomination equal to the portion of the aggregate
principal amount of Outstanding Securities of the series to be represented by
such Global Security or Global Securities. Unless otherwise provided as
contemplated by Section 301, the additional provisions set forth in this Section
304 shall apply to Book-Entry Securities.

         (b) Book-Entry Securities will be deposited with, or on behalf of,
the Depository, and registered in the name of the Depository's nominee, for
credit to the respective accounts of institutions that have accounts with the
Depository or its nominee ("Participants"); provided that Book-Entry Securities
purchased by persons outside the United States may be credited to or through
accounts maintained at the Depository by or on behalf of Euroclear or Cedel. The
accounts to be credited will be designated by the underwriters or agents of such
Securities or, if such Securities are offered and sold directly by the Company,
by the Company. Ownership of beneficial interests in Book-Entry Securities will
be limited to Persons that may hold interests through Participants and will be
shown on records maintained by the Depository or its nominee for such Book-Entry
Security. Participants shall have no rights under this Indenture or any
indenture supplemental hereto with respect to any Book-Entry Security held on
their behalf by the Depository, or the Trustee as its custodian, or under the
Book-Entry Security, and the Depository may be treated by the Company, the
Trustee and any agent of the Company or the Trustee as the absolute owner of the
Book-Entry Security for all purposes whatsoever.

                                       27
<PAGE>   33

Notwithstanding the foregoing, nothing in this Indenture or any such indenture
supplemental shall prevent the Company, the Trustee or any agent of the Company
or the Trustee from giving effect to any written certification, proxy or other
authorization furnished by the Depository or impair, as between the Depository
and its Participants, the operation of customary practices governing the
exercise of the rights of a Holder of any Security.

         (c) Transfers of Book-Entry Securities shall be limited to
transfers in whole, but not in part, to the Depository, its successors or their
respective nominees. Interests of beneficial owners in Book-Entry Securities may
be transferred or exchanged for Bearer Securities only if (i) the Depository
advises the Trustee in writing that it is no longer willing or able to discharge
properly its responsibilities with respect to such Book-Entry Security and it is
unable to locate a qualified successor, (ii) the Company, at its option, elects
to terminate the book-entry system by executing and delivering to the Trustee
and the Depository a notice to such effect, or (iii) there shall have occurred
and be continuing a Default or Event of Default with respect to the Securities
represented by such Book-Entry Security.

         (d) In connection with any transfer or exchange of a portion of
the beneficial interest in any Book-Entry Security to beneficial owners pursuant
to paragraph (c) above, the Security Registrar shall (if one or more Bearer
Securities are to be issued) reflect on its books and records the date and a
decrease in the principal amount of the Book-Entry Security in an amount equal
to the principal amount of the beneficial interest in the Book-Entry Security to
be transferred, and the Company shall execute, and the Trustee shall
authenticate and deliver, one or more Bearer Securities of like tenor and
principal amount of authorized denominations.

         (e) In connection with the transfer of Book-Entry Securities as an
entirety to beneficial owners pursuant to paragraph (c) above, the Book-Entry
Securities shall be deemed to be surrendered to the Trustee for cancellation and
the Company shall execute, and the Trustee shall authenticate and deliver, to
each beneficial owner identified by the Depository in exchange for its
beneficial interest in the Book-Entry Securities, an equal aggregate principal
amount of Bearer Securities of like tenor of authorized denominations.

         (f) The Holder of any Book-Entry Security may grant proxies and
otherwise authorize any person, including Participants and Persons that may hold
interests through Participants, to take any action which a Holder is entitled to
take under the applicable Indenture or the Securities.

SECTION 305. TEMPORARY SECURITIES.

         Pending the preparation of definitive Securities of any series, the
Company may execute, and upon Company Order the Trustee shall authenticate and
deliver, temporary Securities which are typewritten, printed, lithographed,
engraved or otherwise produced by any combination of these methods, in any
authorized denomination, substantially of the tenor of the definitive Securities
in lieu of which they are issued, in registered form or, if authorized, in
bearer form with one or more coupons or without coupons, and with such
appropriate insertions, omissions, substitutions and other variations as the
officers executing such Securities may determine, as

                                       28
<PAGE>   34

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 that are not
issued as Book-Entry Securities as provided in Section 304 (which shall be
exchanged in accordance with the provisions of the following paragraphs), if
temporary Securities of any series are issued, the Company will cause definitive
Securities of that series to be prepared without unreasonable delay. After the
preparation of definitive Securities of such series, the temporary Securities of
such series shall be exchangeable for definitive Securities of such series upon
surrender of the temporary Securities of such series at the office or agency of
the Company in a Place of Payment for that series, without charge to the Holder.
Upon surrender for cancellation of any one or more temporary Securities of any
series (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 the same series of
authorized denominations; provided, however, that no Bearer Security shall be
delivered in exchange for a temporary Registered Security; and provided further
that a Bearer Security shall be delivered in exchange for a temporary Bearer
Security only in compliance with the conditions set forth in Section 303. 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.

         If temporary Securities of any series are issued in global form (other
than Securities issued as Book-Entry Securities as provided in Section 304), any
such temporary Global Security shall, unless otherwise provided therein, be
delivered to the London office of a depositary or common depositary (the "Common
Depositary"), for the benefit of Euroclear and Cedel, for credit to the
respective accounts of the beneficial owners of such Securities (or to such
other accounts as they may direct).

         Without unnecessary delay but in any event not later than the date
specified in, or determined pursuant to the terms of, any such temporary Global
Security that is not issued as a Book-Entry Security as provided in Section 304
(the "Exchange Date"), the Company shall deliver to the Trustee definitive
Securities, in aggregate principal amount equal to the principal amount of such
temporary Global Security, executed by the Company. On or after the Exchange
Date such temporary Global Security shall be surrendered by the Common
Depositary to the Trustee, as the Company's agent for such purpose, to be
exchanged, in whole or from time to time in part, for definitive Securities
without charge and the Trustee shall authenticate and deliver, in exchange for
each portion of such temporary Global Security, an equal aggregate principal
amount of definitive Securities of the same series of authorized denominations
and of like tenor as the portion of such temporary Global Security to be
exchanged. The definitive Securities to be delivered in exchange for any such
temporary Global Security shall be in bearer form, registered form, permanent
global bearer form or permanent global registered form, or any combination
thereof, as specified as contemplated by Section 301, and, if any combination
thereof is so specified, as requested by the beneficial owner thereof; provided,
however, that, unless otherwise specified in such temporary Global Security,
upon such presentation by the Common Depositary, such temporary Global Security
is accompanied by a certificate dated the Exchange

                                       29
<PAGE>   35

Date or a subsequent date and signed by Euroclear as to the portion of such
temporary Global Security held for its account then to be exchanged and a
certificate dated the Exchange Date or a subsequent date and signed by Cedel as
to the portion of such temporary Global Security held for its account then to be
exchanged, each in the form set forth in EXHIBIT A-2 to this Indenture (or in
such other form as may be established pursuant to Section 301); and provided
further that Bearer Securities shall be delivered in exchange for a portion of a
temporary Global Security only in compliance with the requirements of Section
303.

         Unless otherwise specified in such temporary Global Security that is
not issued as a Book-Entry Security as provided in Section 304, the interest of
a beneficial owner of Securities of a series in a temporary Global Security
shall be exchanged for definitive Securities of the same series and of like
tenor following the Exchange Date when the account holder instructs Euroclear or
Cedel, as the case may be, to request such exchange on his behalf and delivers
to Euroclear or Cedel, as the case may be, a certificate in the form set forth
in EXHIBIT A-1 to this Indenture (or in such other form as may be established
pursuant to Section 301), dated no earlier than 15 days prior to the Exchange
Date, copies of which certificate shall be available from the offices of
Euroclear and Cedel, the Trustee, any Authenticating Agent appointed for such
series of Securities and each Paying Agent. Unless otherwise specified in such
temporary Global Security, any such exchange shall be made free of charge to the
beneficial owners of such temporary Global Security, except that a Person
receiving definitive Securities must bear the cost of insurance, postage,
transportation and the like in the event that such Person does not take delivery
of such definitive Securities in person at the offices of Euroclear or Cedel.
Bearer Securities in bearer form to be delivered in exchange for any portion of
a temporary Global Security shall be delivered only outside the United States.

         Until exchanged in full as hereinabove provided, the temporary
Securities of any series, including temporary Global Securities (whether or not
issued as Book-Entry Securities as provided in Section 304), shall in all
respects be entitled to the same benefits under this Indenture as definitive
Securities of the same series and of like tenor authenticated and delivered
hereunder, except that, unless otherwise specified as contemplated by Section
301, interest payable on a temporary Global Security (other than Securities
issued as Book-Entry Securities as provided in Section 304) on an Interest
Payment Date for Securities of such series occurring prior to the applicable
Exchange Date shall be payable to Euroclear and Cedel on such Interest Payment
Date upon delivery by Euroclear and Cedel to the Trustee of a certificate or
certificates in the form set forth in EXHIBIT A-2 to this Indenture (or in such
other form as may be established pursuant to Section 301), for credit without
further interest thereon on or after such Interest Payment Date to the
respective accounts of the Persons who are the beneficial owners of such
temporary Global Security on such Interest Payment Date and who have each
delivered to Euroclear or Cedel, as the case may be, a certificate dated no
earlier than 15 days prior to the Interest Payment Date occurring prior to such
Exchange Date in the form set forth in EXHIBIT A-1 to this Indenture (or in such
other form as may be established pursuant to Section 301). Notwithstanding
anything to the contrary herein contained, the certifications made pursuant to
this paragraph shall satisfy the certification requirements of the preceding two
paragraphs of this Section and of the third paragraph of Section 303 of this
Indenture and the interests of the Persons who are the beneficial owners of the
temporary Global Security with respect to which such certification was made will
be exchanged for definitive Securities of the same series and of like tenor on
the Exchange Date or the date of certification if such date occurs after the
Exchange Date, without further act or deed by such beneficial owners. Except as
otherwise provided in this

                                       30
<PAGE>   36

paragraph, no payments of principal (or premium, if any) or interest, if any,
owing with respect to a beneficial interest in a temporary Global Security will
be made unless and until such interest in such temporary Global Security shall
have been exchanged for an interest in a definitive Security. Any interest so
received by Euroclear and Cedel and not paid as herein provided shall be
returned to the Trustee immediately prior to the expiration of two years after
such Interest Payment Date in order to be repaid to the Company in accordance
with Section 1003.

SECTION 306. REGISTRATION, REGISTRATION OF TRANSFER AND EXCHANGE.

         The Company shall cause to be kept at the Corporate Trust Office of the
Trustee a register for each series of Securities (the registers maintained in
such office of the Trustee and in any other office or agency designated pursuant
to Section 1002 being herein sometimes referred to as the "Security Register")
in which, subject to such reasonable regulations as it may prescribe, the
Company shall provide for the registration of Registered Securities and of
transfers of Registered Securities. The Trustee is hereby initially appointed
"Security Registrar" for the purpose of registering Registered Securities and
transfers of Registered Securities as herein provided.

         Except as otherwise described in this Article Three, upon surrender for
registration of transfer of any Registered Security of any series at the office
or agency in a Place of Payment for that 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, in each case, of any authorized denominations and of a like aggregate
principal amount.

         At the option of the Holder, Registered Securities of any series may be
exchanged for other Registered Securities of the same series, of any authorized
denominations and of a like aggregate principal amount, upon surrender of the
Registered Securities to be exchanged at such office or agency. Whenever any
Registered Securities are so surrendered for exchange, the Company shall
execute, and the Trustee shall authenticate and make available for delivery, the
Registered Securities which the Holder making the exchange is entitled to
receive. Unless otherwise specified with respect to any series of Securities as
contemplated by Section 301 or Section 304, Bearer Securities may not be issued
in exchange for Registered Securities.

         If (but only if) expressly permitted in or pursuant to the applicable
Board Resolution and (subject to Section 303) set forth in the applicable
Officers' Certificate, or in any indenture supplemental hereto, delivered as
contemplated by Section 301, at the option of the Holder, Bearer Securities of
any series may be exchanged for Registered Securities of the same series of any
authorized denomination and of a like aggregate principal amount and tenor, upon
surrender of the Bearer Securities to be exchanged at any such office or agency,
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, any such
permitted exchange may be effected if the Bearer Securities are accompanied by
payment in funds acceptable to the Company 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

                                       31
<PAGE>   37

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 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 1002,
interest represented by coupons shall be payable only upon presentation and
surrender of those coupons at an office or agency located outside the United
States. Notwithstanding the foregoing, in case a Bearer Security of any series
is surrendered at any such office or agency in a permitted exchange for a
Registered Security of the same 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 relevant Interest Payment
Date, or (ii) any Special Record Date and before the opening of business at such
office or agency on the related proposed date for payment of Defaulted Interest,
such Bearer Security shall be surrendered without the coupon relating to such
Interest Payment Date or proposed date for payment, as the case may be, and
interest or Defaulted Interest, as the case may be, will 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 will be payable only to the Holder of such coupon when due in accordance
with the provisions of this Indenture.

         Whenever any Securities are so surrendered for exchange, the Company
shall execute, and the Trustee shall authenticate and deliver, the Securities
which the Holder making the exchange is entitled to receive, and the Trustee
shall cancel the Bearer Securities so transferred. In the case of an exchange of
Bearer Securities for an interest in a Book-Entry Security, the Security
Registrar shall reflect on the Register the date and an increase in the
principal amount of the Bearer Securities to be transferred, and the Trustee
shall cancel the Bearer Securities so transferred.

         Notwithstanding the foregoing, except as otherwise specified as
contemplated by Section 301, any permanent Global Security (other than
Securities issued as Book-Entry Securities as provided in Section 304) shall be
exchangeable only as provided in this paragraph. If any beneficial owner of an
interest in a permanent Global Security is entitled to exchange such interest
for Securities of such series and of like tenor and principal amount of another
authorized form and denomination, as specified as contemplated by Section 301
and provided that any applicable notice provided in the permanent Global
Security shall have been given, then without unnecessary delay but in any event
not later than the earliest date on which such interest may be so exchanged, the
Company shall deliver to the Trustee definitive Securities in aggregate
principal amount equal to the principal amount of such beneficial owner's
interest in such permanent Global Security, executed by the Company. On or after
the earliest date on which such interests may be so exchanged, such permanent
Global Security shall be surrendered by the Common Depositary or such other
depositary 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 from time to time in part, for definitive Securities without charge, and the
Trustee shall authenticate and deliver, in exchange for each portion of such
permanent Global Security, an equal aggregate principal amount of definitive
Securities of the same series of authorized denominations and of like tenor as
the portion of such permanent Global Security to be exchanged which, unless the
Securities of the series are not issuable both as Bearer Securities and as
Registered Securities, as specified as contemplated by Section 301, shall be in
the form of

                                       32
<PAGE>   38

Bearer Securities or Registered Securities, or any combination thereof, as shall
be specified by the beneficial owner thereof; provided, however, that no such
exchanges may occur during a period beginning at the opening of business 15 days
before any selection of Securities to be redeemed and ending on the relevant
Redemption Date if the Security for which exchange is requested may be among
those selected for redemption; and provided further that no Bearer Security
delivered in exchange for a portion of a permanent Global Security shall be
mailed or otherwise delivered to any location in the United States. If a
Registered Security is issued in exchange for any portion of a permanent Global
Security after the close of business at the office or agency where such exchange
occurs on (i) any Regular Record Date and before the opening of business at such
office or agency on the relevant Interest Payment Date, or (ii) any Special
Record Date and before the opening of business at such office or agency on the
related proposed date for payment of Defaulted Interest, interest or Defaulted
Interest, as the case may be, will 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 will 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 permanent Global Security is 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 entitled 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 shall (if so required by the Company or the Security
Registrar) be duly endorsed, or be accompanied by a written instrument of
transfer, in form satisfactory to the Company and the Security Registrar, 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 of Securities, but the Company may require payment of a sum sufficient
to pay all documentary, stamp, similar issue or transfer taxes or other
governmental charges that may be imposed in connection with any registration of
transfer or exchange of Securities, other than exchanges pursuant to Section
305, 906, 1107 or 1305 not involving any transfer.

         The Company shall not be required (i) to issue, register the transfer
of or exchange Securities of any series during a period beginning at the opening
of business 15 days before the day of the selection for redemption of Securities
of that series under Section 1103 or 1203 and ending at the close of business on
(A) if Securities of the series are issuable only as Registered Securities, the
day of the mailing of the relevant notice of redemption and (B) if Securities of
the series are issuable as Bearer Securities, the day of the first publication
of the relevant notice of redemption or, if Securities of the series are also
issuable as Registered Securities and there is no publication, the mailing of
the relevant notice of redemption, or (ii) to register the transfer of or
exchange any Registered Security so selected for redemption in whole or in part,
except the unredeemed portion of any Security being redeemed in part, or (iii)
to exchange any Bearer Security so selected for redemption except that such a
Bearer Security may be exchanged for a Registered Security of that series and
like tenor; provided that such Registered Security shall be

                                       33
<PAGE>   39

simultaneously surrendered for redemption, or (iv) to issue, register the
transfer of or exchange any Security which 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 307. 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 together with, in proper cases,
such security or indemnity as may be required by the Company or the Trustee to
save each of them and any agent of either of them harmless, the Company shall
execute and the Trustee shall authenticate and deliver in exchange therefor a
new Security of the same series and of like tenor and principal amount and
bearing a number not contemporaneously outstanding, with coupons corresponding
to the coupons, if any, appertaining to the surrendered Security, or, in case
any such mutilated 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,
with coupons corresponding to the coupons, if any, appertaining to the
surrendered Security, pay such Security or coupon.

         If there shall be delivered to the Company and to the Trustee (i)
evidence to their satisfaction of the destruction, loss or theft of any Security
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 Company
Order the Trustee shall authenticate and deliver, in lieu of any such destroyed,
lost or stolen Security or in exchange for the Security for which a destroyed,
lost or stolen coupon appertains (with all appurtenant coupons not destroyed,
lost or stolen), a new Security of the same series and of like tenor and
principal amount and bearing a number not contemporaneously outstanding, with
coupons 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 provisions of the previous two paragraphs, in case
any such 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, with coupons corresponding to the coupons, if any,
appertaining to such mutilated, destroyed, lost or stolen Security or to the
Security to which such mutilated, destroyed, lost or stolen coupon appertains,
pay such Security or coupon; provided, however, that payment of principal of
(and premium, if any) and interest, if any, on Bearer Securities shall, except
as otherwise provided in Section 1002, be payable only at an office or agency
located outside the United States and, unless otherwise specified as
contemplated by Section 301, any interest on Bearer Securities shall be payable
only upon presentation and surrender of the coupons appertaining thereto.

         Upon the issuance of any new Security under this Section, the Company
may require the payment of a sum sufficient to pay all documentary, stamp or
similar issue or transfer taxes or other governmental charges that may be
imposed in relation thereto and any other expenses (including the fees and
expenses of the Trustee) connected therewith.

                                       34
<PAGE>   40

         Every new Security of any series with its coupons, if any, issued
pursuant to this Section in lieu of any mutilated, destroyed, lost or stolen
Security or in exchange for a Security to which a mutilated, destroyed, lost or
stolen coupon appertains, shall constitute an original additional contractual
obligation of the Company, whether or not the mutilated, destroyed, lost or
stolen Security and its coupons, if any, or the mutilated, 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 that series and their coupons, if any, duly issued
hereunder.

         The provisions of this Section 307 are exclusive and shall preclude (to
the extent lawful) all other rights and remedies with respect to the replacement
or payment of mutilated, destroyed, lost or stolen Securities or coupons.

SECTION 308. PAYMENT OF INTEREST; INTEREST RIGHTS PRESERVED.

         Unless otherwise provided as contemplated by Section 301 with respect
to any series of Securities, interest, if any, on any Registered Security which
is payable, and is punctually paid or duly provided for, on any Interest Payment
Date shall be paid to the Person in whose name such Security (or one or more
Predecessor Securities) is registered at the close of business on the Regular
Record Date for such interest at the office or agency of the Company maintained
for such purpose pursuant to Section 1002: provided, however, that each
installment of interest, if any, on any Registered Security may at the Company's
option be paid by (i) mailing a check for such interest, payable to or upon the
written order of the Person entitled thereto pursuant to Section 310, to the
address of such Person as it appears on the Security Register or (ii) transfer
to an account located in the United States maintained by the payee.

         Unless otherwise provided as contemplated by Section 301 with respect
to the Securities of any series, in the case of any Security which is converted
in accordance with Article Sixteen after any Regular Record Date and on or prior
to the next succeeding Interest Payment Date (other than any Security whose
Maturity is prior to such Interest Payment Date), interest whose Stated Maturity
is on such Interest Payment Date shall be payable on such Interest Payment Date
notwithstanding such conversion, and such interest (whether or not punctually
paid or duly provided for) shall be paid to the Person in whose name that
Security (or one or more Predecessor Securities) is registered at the close of
business on such Regular Record Date. Except as otherwise expressly provided in
the immediately preceding sentence or in Section 1602, in the case of any
Security which is converted, interest whose stated Maturity is after the date of
conversion of such Security shall not be payable.

         Unless otherwise provided as contemplated by Section 301 with respect
to the Securities of any series, payment of interest, if any, may be made, in
the case of a Bearer Security, by transfer to an account located outside the
United States maintained by the payee.

         Unless otherwise provided as contemplated by Section 301, every
permanent Global Security (other than Book-Entry Securities issued as provided
in Section 304) will provide that interest, if any, payable on any Interest
Payment Date will be paid to each of Euroclear and Cedel with respect to that
portion of such permanent Global Security held for its account by the

                                       35
<PAGE>   41

Common Depositary, for the purpose of permitting each of Euroclear and Cedel to
credit the interest, if any, received by it in respect of such permanent Global
Security to the accounts of the beneficial owners thereof.

         Any interest on any Registered Security of any series which is payable,
but is not punctually paid or duly provided for, on any Interest Payment Date
shall forthwith cease to be payable to the Holder on the relevant Regular Record
Date by virtue of having been such Holder, and such defaulted interest and, if
applicable, interest on such defaulted interest (to the extent lawful) at the
rate specified in the Securities of such series (such defaulted interest and, if
applicable, interest thereon herein collectively called "Defaulted Interest")
may be paid by the Company, at its election in each case, as provided in
Subsection (1) or (2) below:

                  (1) The Company may elect to make payment of any Defaulted
Interest to the Persons in whose names the Registered Securities of such series
(or their respective Predecessor Securities) are registered at the close of
business on a Special Record Date for the payment of such Defaulted Interest,
which shall be fixed in the following manner. The Company shall notify the
Trustee in writing of the amount of Defaulted Interest proposed to be paid on
each Registered Security of such series and the date of the proposed payment,
and at the same time the Company shall deposit with the Trustee an amount of
money in the Currency in which the Securities of such series are payable (except
as otherwise specified pursuant to Section 301 for the Securities of such series
and except, if applicable, as provided in Sections 313(b), 313(d) and 313(e))
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 deposited to be
held in trust for the benefit of the Persons entitled to such Defaulted Interest
as in this Subsection provided. Thereupon the Trustee shall fix a Special Record
Date for the payment of such Defaulted Interest which shall be not more than 15
days and not less than 10 days prior to the date of the proposed payment and not
less than 10 days after the receipt by the Trustee of the notice of the proposed
payment. The Trustee shall promptly notify the Company of such Special Record
Date and, in the name and at the expense of the Company, shall cause notice of
the proposed payment of such Defaulted Interest and the Special Record Date
therefor to be given in the manner provided in Section 106, not less than 10
days prior to such Special Record Date. Notice of the proposed payment of such
Defaulted Interest and the Special Record Date therefor having been so given,
such Defaulted Interest shall be paid to the Persons in whose name the
Registered Securities of such series (or their respective Predecessor
Securities) are registered at the close of business on such Special Record Date
and shall no longer be payable pursuant to the following Subsection (2).

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

SECTION 309. Intentionally left blank.

                                       36
<PAGE>   42

SECTION 310. 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 as the
owner of such Registered Security for the purpose of receiving payment of
principal of (and premium, if any) and (subject to Sections 306 and 308)
interest, if any, on such Security and for all other purposes whatsoever,
whether or not such Security 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.

         Title to any Bearer Security and any coupons appertaining thereto shall
pass by delivery. The Company, the Trustee and any agent of the Company or the
Trustee may treat the bearer of any Bearer Security and 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 such Security or coupons 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.

         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 Security in global form or for maintaining, supervising or
reviewing any records relating to such beneficial ownership interests.

         Notwithstanding the foregoing, with respect to any Global Security,
nothing herein shall prevent the Company, the Trustee, or any agent of the
Company or the Trustee, from giving effect to any written certification, proxy
or other authorization furnished by any depositary, as a Holder, with respect to
such Global Security or impair, as between such depositary and owners of
beneficial interests in such Global Security, the operation of customary
practices governing the exercise of the rights of such depositary (or its
nominee) as Holder of such Global Security.

SECTION 311. CANCELLATION.

         All Securities and coupons surrendered for payment, redemption,
repayment at the option of the Holder, registration of transfer or exchange or
for credit against any current or future sinking fund payment shall, if
surrendered to any Person other than the Trustee, be delivered to the Trustee.
All Securities and coupons so delivered to the Trustee shall be promptly
canceled by it. The Company may at any time deliver to the Trustee for
cancellation any Securities previously authenticated and delivered hereunder
which the Company may have acquired in any manner whatsoever, and may deliver to
the Trustee (or to any other Person for delivery to the Trustee) for
cancellation any Securities previously authenticated hereunder which the Company
has not issued and sold, and all Securities so delivered shall be promptly
canceled by the Trustee. If the Company shall so acquire any of the Securities,
however, such acquisition shall not operate as a redemption or satisfaction of
the indebtedness represented by such Securities unless and until the same are
surrendered to the Trustee for cancellation. No Securities shall be
authenticated in lieu of or in exchange for any Securities canceled as provided
in this Section,

                                       37
<PAGE>   43

except as expressly permitted by this Indenture. All canceled Securities held by
the Trustee shall be disposed of by the Trustee in accordance with its customary
procedures, unless by Company Order the Company shall direct that canceled
Securities be returned to it.

SECTION 312. COMPUTATION OF INTEREST.

         Except as otherwise specified as contemplated by Section 301 with
respect to any Securities, interest, if any, on the Securities of each series
shall be computed on the basis of a 360-day year of twelve 30-day months.

SECTION 313. CURRENCY AND MANNER OF PAYMENTS IN RESPECT OF SECURITIES.

         (a) With respect to Registered Securities of any series not
permitting the election provided for in paragraph (b) below or the Holders of
which have not made the election provided for in paragraph (b) below, and with
respect to Bearer Securities of any series, except as provided in paragraph (d)
below, payment of the principal of (and premium, if any) and interest, if any,
on any Registered or Bearer Security of such series will be made in Dollars. The
provisions of this Section 313 may be modified or superseded with respect to any
Securities pursuant to Section 301.

         (b) It may be provided pursuant to Section 301 with respect to
Registered Securities of any series that Holders shall have the option, subject
to paragraph (d) below, to receive payments of principal of (or premium, if any)
or interest, if any, on such Registered Securities in any of the Currencies
which may be designated for such election by delivering to the Trustee a written
election with signature guaranties and in the applicable form established
pursuant to Section 301, not later than the close of business on the Election
Date immediately preceding the applicable payment date. If a Holder so elects to
receive such payments in any such Currency, such election will remain in effect
for such Holder or any transferee of such Holder until changed by such Holder or
such transferee by written notice to the Trustee (but any such change must be
made not later than the close of business on the Election Date immediately
preceding the next payment date to be effective for the payment to be made on
such payment date and no such change of election may be made with respect to
payments to be made on any Registered Security of such series with respect to
which an Event of Default has occurred or with respect to which the Company has
deposited funds pursuant to Article Four or Fourteen or with respect to which a
notice of redemption has been given by the Company or a notice of option to
elect repayment has been sent by such Holder or such transferee). Any Holder of
any such Registered Security who shall not have delivered any such election to
the Trustee not later than the close of business on the applicable Election Date
will be paid the amount due on the applicable payment date in the relevant
Currency as provided in Section 313(a). The Trustee shall notify the Exchange
Rate Agent as soon as practicable after the Election Date of the aggregate
principal amount of Registered Securities for which Holders have made such
written election.

         (c) Unless otherwise specified pursuant to Section 301, if the
election referred to in paragraph (b) above has been provided for pursuant to
Section 301, then, unless otherwise specified pursuant to Section 301, not later
than the fourth Business Day after the Election Date

                                       38

for each payment date for Registered Securities of any series, the Exchange Rate
Agent will deliver to the Company a written notice specifying, in the Currency
in which Registered Securities of such series are payable, the respective
aggregate amounts of principal of (and premium, if any) and interest, if any, on
the Registered Securities to be paid on such payment date, specifying the
amounts in such Currency so payable in respect of the Registered Securities as
to which the Holders of Registered Securities of such series shall have elected
to be paid in another Currency as provided in paragraph (b) above. If the
election referred to in paragraph (b) above has been provided for pursuant to
Section 301 and if at least one Holder has made such election, then, unless
otherwise specified pursuant to Section 301, on the second Business Day
preceding such payment date the Company will deliver to the Trustee for such
series of Registered Securities an Exchange Rate Officers' Certificate in
respect of the Dollar or Foreign Currency payments to be made on such payment
date. Unless otherwise specified pursuant to Section 301, the Dollar or Foreign
Currency amount receivable by Holders of Registered Securities who have elected
payment in a Currency as provided in paragraph (b) above shall be determined by
the Company on the basis of the applicable Market Exchange Rate in effect on the
third Business Day (the "Valuation Date") immediately preceding each payment
date, and such determination shall be conclusive and binding for all purposes,
absent manifest error.

         (d) Unless otherwise specified pursuant to Section 301, if the
Holder of a Registered Security shall have elected to be paid in a Currency
other than Dollars as provided in paragraph (b) above, and a Currency Conversion
Event occurs with respect to such elected Currency, such Holder shall receive
payment in Dollars.

         (e) The "Dollar Equivalent of the Foreign Currency" shall be
determined by the Exchange Rate Agent and shall be obtained for each subsequent
payment date by converting the specified Foreign Currency into Dollars at the
Market Exchange Rate on the Currency Conversion Date.

         (f) The "Dollar Equivalent of the Currency Unit" shall be
determined as specified pursuant to Section 301. "Election Date" shall mean the
date for any series of Registered Securities as specified pursuant to clause
(11) of Section 301 by which the written election referred to in paragraph (b)
above may be made.

         All decisions and determinations of the Exchange Rate Agent regarding
the Dollar Equivalent of the Foreign Currency, the Dollar Equivalent of the
Currency Unit, the Market Exchange Rate and changes in the Specified Amounts as
specified above shall be in its sole discretion and shall, in the absence of
manifest error, be conclusive for all purposes and irrevocably binding upon the
Company, the Trustee and all Holders of such Securities denominated or payable
in the relevant Currency. The Exchange Rate Agent shall promptly give written
notice to the Company and the Trustee of any such decision or determination.

         Except as otherwise provided pursuant to Section 301, in the event that
the Company determines in good faith that a Currency Conversion Event has
occurred with respect to a Foreign Currency, the Company will immediately give
written notice thereof to the Trustee and to the Exchange Rate Agent (and the
Trustee will promptly thereafter give notice in the manner provided for in
Section 106 to the affected Holders) specifying the Currency Conversion Date.

                                       39
<PAGE>   45

Except as otherwise provided pursuant to Section 301, in the event the Company
so determines that a Currency Conversion Event has occurred with respect to any
currency unit in which Securities are payable, the Company will immediately give
written notice thereof to the Trustee and to the Exchange Rate Agent (and the
Trustee will promptly thereafter give notice in the manner provided for in
Section 106 to the affected Holders) specifying the Currency Conversion Date and
the Specified Amount of each Component Currency on the Currency Conversion Date.
In the event the Company determines in good faith that any subsequent change in
any Component Currency as set forth in the definition of Specified Amount above
has occurred, the Company will similarly give written notice to the Trustee and
the Exchange Rate Agent.

         The Trustee shall be fully justified and protected in relying and
acting upon information received by it from the Company and the Exchange Rate
Agent and shall not otherwise have any duty or obligation to determine the
accuracy or validity of such information independent of the Company or the
Exchange Rate Agent.

SECTION 314. APPOINTMENT AND RESIGNATION OF SUCCESSOR EXCHANGE RATE AGENT.

         (a) Unless otherwise specified pursuant to Section 301, if and so
long as the Securities of any series may be payable in a Currency other than
Dollars, 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. The Company
will cause the Exchange Rate Agent to make the necessary foreign exchange
determinations at the time and in the manner specified pursuant to Section 301
for the purpose of determining the applicable rate of exchange and, if
applicable, for the purpose of converting Dollars into the applicable payment
Currency for the payment of principal (and premium, if any) and interest, if
any, pursuant to Section 313.

         (b) No resignation of the Exchange Rate Agent and no appointment
of a successor Exchange Rate Agent pursuant to this Section shall become
effective until the acceptance of appointment by the successor Exchange Rate
Agent as evidenced by a written instrument delivered to the Company and the
Trustee.

         (c) If the Exchange Rate Agent shall resign, be removed or become
incapable of acting, or if a vacancy shall occur in the office of the Exchange
Rate Agent 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 Exchange Rate Agent or Exchange Rate Agents with respect to the
Securities of that or those series (it being understood that any such successor
Exchange Rate Agent may be appointed with respect to the Securities of one or
more or all of such series and that, unless otherwise specified pursuant to
Section 301, at any time there shall only be one Exchange Rate Agent with
respect to the Securities of any particular series that are originally issued by
the Company on the same date and that are payable in the same Currency).

SECTION 315. CUSIP NUMBERS.

         The Company in issuing the Securities may use "CUSIP" numbers (if then
generally in use) in addition to serial numbers, and, if so, the Trustee shall
use such "CUSIP" numbers in addition to serial numbers in notices 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 and that reliance may be placed
only on the serial or other identification numbers printed on the Securities,
and any such notice shall not be affected by any defect in or omission of such
"CUSIP" numbers. The Company will promptly notify the Trustee of any change in
the "CUSIP" numbers.

SECTION 401. SATISFACTION AND DISCHARGE OF INDENTURE.

         This Indenture shall, upon Company Request, cease to be of further
effect with respect to any series of Securities specified in such Company
Request (except as to any surviving rights of registration of transfer or
exchange of Securities of such series expressly provided for herein or pursuant
hereto) and the Trustee, on demand of and 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, if any, appertaining thereto (other
than (i) coupons appertaining to Bearer Securities surrendered for exchange for
Registered Securities and maturing after such exchange, whose surrender is not
required or has been waived as provided in Section 306, (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 307, (iii) coupons appertaining to
Securities called for redemption and maturing after the relevant Redemption
Date, whose surrender has been waived as provided in Section 1106, and (iv)
Securities and coupons of such series for whose payment money has theretofore
been deposited in trust with the Trustee or any Paying Agent or segregated and
held in trust by the Company and thereafter repaid to the Company or discharged
from such Trust, as provided in Section 1003) have been delivered to the Trustee
for cancellation; or

                      (B) all Securities of such series and, in the case of (i)
or (ii) below, any coupons appertaining thereto not theretofore delivered to the
Trustee for cancellation

                          (i) have become due and payable, or

<PAGE>   47

                          (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 irrevocably deposited or caused to be deposited with the
Trustee as trust funds in trust for such purpose an amount in the Currency in
which the Securities of such series are payable, sufficient to pay and discharge
the entire indebtedness on such Securities not theretofore delivered to the
Trustee for cancellation, for principal (and premium, if any) and interest, if
any, to the date of such deposit (in the case of Securities which have become
due and payable) or to the Stated Maturity or Redemption Date, as the case may
be:

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

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

         Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Company to the Trustee under Section 606, the obligations of
the Trustee to any Authenticating Agent under Section 612 and, if money shall
have been deposited with the Trustee pursuant to subclause (B) of Subsection (1)
of this Section, the obligations of the Trustee under Section 402 and the last
paragraph of Section 1003 shall survive.

SECTION 402. APPLICATION OF TRUST MONEY.

         Subject to the provisions of the last paragraph of Section 1003, all
money deposited with the Trustee pursuant to Section 401 shall be held in trust
and applied by it, in accordance with the provisions of the Securities, the
coupons and this Indenture, to the payment, either directly or through any
Paying Agent (including the Company acting as its own Paying Agent) as the
Trustee may determine, to the Persons entitled thereto, of the principal (and
premium, if any) and interest, if any, for whose payment such money has been
deposited with the Trustee. If the Trustee or Paying Agent is unable to apply
any money or Government Obligations in accordance with Section 401 by reason of
any legal proceeding or by reason of any order or judgment of any court or
governmental authority enjoining, restraining or otherwise prohibiting such
application, the Company's obligations under this Indenture shall be revived and
reinstated as though no deposit had occurred pursuant to Section 401; provided
that if the Company has made any payment of principal of, premium, if any, or
interest on the Securities because of the reinstatement of its obligations, the
Company shall be subrogated to the rights of the Holders of the Securities to
receive such payment from the money or Government Obligations held by the
Trustee or Paying Agent.

SECTION 501. EVENTS OF DEFAULT.

         "Event of Default", wherever used herein, means any one of the
following events (whatever the reason for such Event of Default and whether it

Company by the Trustee or to the Company and the Trustee by the Holders of at
least 25% in aggregate principal amount of the Securities then outstanding;

                  (5) there occurs with respect to any issue or issues of
Indebtedness of the Company or any Restricted Subsidiary having an outstanding
principal amount of $50,000,000 or more in the aggregate for all such issues of
all such Persons, whether such Indebtedness exists on the date of this Indenture
or is hereafter created, (a) an event of default that has caused the holder
thereof to declare such Indebtedness to be due and payable prior to its stated
maturity and such Indebtedness shall not have been discharged in full or such
acceleration shall not have been rescinded or annulled within 30 days of such
acceleration and/or (b) the failure to make a principal payment at the final
(but not any interim) fixed maturity and such defaulted payment shall not have
been made, waived or extended within 30 days of such payment default;

                  (6) failure by the Company or any of its Restricted
Subsidiaries to pay, bond or otherwise discharge within 60 days one or more

of which exceeds in the aggregate $50,000,000, which judgments or court orders
are not stayed on appeal or are not otherwise being appropriately contested in
good faith;

                  (7) a court having jurisdiction in the premises enters a

Subsidiary or for all or substantially all of the property and assets of the
Company or any Restricted Subsidiary or (iii) the winding up or liquidation of
the affairs of the Company or any Restricted Subsidiary and, in each case, such
decree or order shall remain unstayed and in effect for a period of 60

                  (9) any other Event of Default provided with respect to
Securities of that series.

SECTION 502. ACCELERATION OF MATURITY; RESCISSION AND ANNULMENT.

         If an Event of Default (other than as specified in Section 501(7) or
(8)) occurs and is continuing, the Trustee or the Holders of not less than 25%
in aggregate principal amount of the Securities of any series then outstanding
may, and the Trustee at the request of such Holders shall, declare the principal
of all of the outstanding Securities of such series immediately due and payable,
by a notice in writing to the Company (and to the Trustee if given by the
Holders) and, upon any such declaration, such principal shall become due and
payable immediately. If an Event of Default specified in Section 501(7) or (8)
above occurs and is continuing, then such principal 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 Securities.

         At any time after a declaration of acceleration under this Indenture,
but before a judgment or decree for payment of the money due has been obtained
by the Trustee, the Holders of a majority in aggregate principal amount of the
outstanding Securities, by written notice to the Company and the Trustee, may
rescind such declaration and its consequences if:

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

                           (A) all overdue interest on all Securities,

                           (B) all unpaid principal of (and premium, if any, on)
                  any outstanding Securities that has become due otherwise than
                  by such declaration of acceleration and interest thereon at
                  the rate borne by the Securities,

                           (C) to the extent that payment of such interest is
                  lawful, interest upon overdue interest and overdue principal
                  amount at the rate borne by the Securities, and

                                       44
<PAGE>   50

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

                  (ii) all Events of Default, other than the non-payment of
amounts of principal of (or premium, if any, on) or interest on the Securities
that have become due solely by such declaration of acceleration, have been cured
or waived.

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

SECTION 503. COLLECTION OF INDEBTEDNESS AND SUITS FOR ENFORCEMENT BY TRUSTEE.

         The Company covenants that if:

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

         (b) default is made in the payment of the principal of (or premium, if
any, on) any Security at the Stated Maturity or other maturity thereof,

the Company shall, upon demand of the Trustee, pay to the Trustee for the
benefit of the Holders of such Securities, the whole amount then due and payable
on such Securities for principal (and premium, if any) and interest, with
interest upon the overdue principal (and premium, if any) and, to the extent
that payment of such interest shall be legally enforceable, upon overdue
installments of interest, at the rate borne by the Securities; and, in addition
thereto, such further amount as shall be sufficient to cover the costs and
expenses of collection, including the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel and all other
amounts due to the Trustee under Section 606.

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

         If an Event of Default with respect to Securities of any series (or of
all series, as the case may be) occurs and is continuing, the Trustee may in its
discretion proceed to protect and enforce its rights and the rights of the
Holders by such appropriate judicial proceedings as the Trustee shall deem most
effectual to protect and enforce such rights, whether for the specific
enforcement of any covenant or agreement in this Indenture or in aid of the
exercise of any power granted herein, or to enforce any other proper remedy
subject, however, to Section 513. No recovery of any such judgment upon any
property of the Company shall affect or impair any rights, powers or remedies of
the Trustee or the Holders.

SECTION 504. 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, upon the Securities or the property
of the Company or of 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
overdue principal, premium, if any, or interest) shall be entitled and
empowered, by intervention in such proceeding or otherwise,

                  (i) to file and prove a claim for the whole amount of
principal (and premium, if any) and interest owing and unpaid in respect of the
Securities, to take such other actions (including participating as a member,
voting or otherwise, of any official committee of creditors appointed in such
matter) 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 and counsel) and of the Holders allowed in such judicial
proceeding, and

                  (ii) to collect and receive any moneys or other property
payable or deliverable on any such claims and to distribute the same;

and any Custodian in any such judicial proceeding is hereby authorized by each
Holder to make such payments to the Trustee and, in the event that the Trustee
shall consent to the making of such payments directly to the Holders, to pay the
Trustee any amount due it for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, and any other
amounts due the Trustee under Section 606.

         Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Holder any plan of
reorganization, arrangement, adjustment or composition affecting the Securities
or the rights of any Holder thereof, or to authorize the Trustee to vote in
respect of the claim of any Holder in any such proceeding; provided, however,
that the Trustee may, on behalf of such Holders, vote for the election of a
trustee in bankruptcy or other similar official.

SECTION 505. TRUSTEE MAY ENFORCE CLAIMS WITHOUT POSSESSION OF SECURITIES.

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

SECTION 506. APPLICATION OF MONEY COLLECTED.

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

such Securities for principal (and premium, if any) and interest, respectively;
and

         THIRD: The balance, if any, to the Person or Persons entitled thereto,
including the Company or any other obligor on the Securities, as their interests
may appear or as a court of competent jurisdiction may direct, provided that all
sums due and owing to the Holders and the Trustee have been paid in full as
required by this Indenture.

SECTION 507. LIMITATION ON SUITS.

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

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

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

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

         (4) the Trustee for 30 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 30-day period by the Holders of a majority or
more in principal amount of the Outstanding Securities of that series;

<PAGE>   53

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 to affect, disturb or prejudice the rights of any other
Holders of Securities of the same series or to obtain or to seek to obtain
priority or preference over any other of such Holders or to enforce any right
under this Indenture, except in the manner herein provided and for the equal and
ratable benefit of all Holders of Securities of the same series.

SECTION 508. UNCONDITIONAL RIGHT OF HOLDERS TO RECEIVE PRINCIPAL, PREMIUM AND
INTEREST.

         Notwithstanding any other provision in this Indenture, the Holder of
any Security shall have the right, which is absolute and unconditional, to
receive payment of the principal of (and premium, if any) and (subject to
Section 308) interest, if any, on, such Security or payment of such coupon on
the respective Stated Maturities expressed in such Security or coupon (or, in
the case of redemption, on the Redemption Date) and to institute suit for the
enforcement of any such payment, and such rights shall not be impaired without
the consent of such Holder.

SECTION 509. RESTORATION OF RIGHTS AND REMEDIES.

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

SECTION 510. RIGHTS AND REMEDIES CUMULATIVE.

         Except as otherwise provided in Section 307, no right or remedy herein
conferred upon or reserved to the Trustee or to the Holders of Securities or
coupons is intended to be exclusive of any other right or remedy, and every
right and remedy shall, to the extent permitted by law, be cumulative and in
addition to every other right and remedy given hereunder or now or hereafter
existing at law or in equity or otherwise. The assertion or employment of any
right or remedy hereunder, or otherwise, shall not prevent the concurrent
assertion or employment of any other appropriate right or remedy.

SECTION 511. DELAY OR OMISSION NOT WAIVER.

         No delay or omission of the Trustee or of any Holder of any Security 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 the Holders may be exercised from time to time,
and as often as may be deemed expedient, by the Trustee or by the Holders, as
the case may be.

SECTION 512. CONTROL BY HOLDERS.

         With respect to the Securities of any series, the Holders of not less
than a majority in principal amount of the Outstanding Securities of such 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, provided that in each case

         (1) such direction shall not be in conflict with any rule of law or
with this Indenture or expose the Trustee to personal liability;

         (2) the Trustee need not take any action which might involve it in
personal liability or be unjustly prejudicial to the Holders not consenting; and

         (3) subject to the provisions of the TIA Section 315, the Trustee
may take any other action deemed proper by the Trustee which is not inconsistent
with such direction.

SECTION 513. WAIVER OF PAST DEFAULTS.

         Subject to Section 502, the Holders of not less than a majority in
principal amount of the Outstanding Securities of any series may on behalf of
the Holders of all the Securities of such series waive any past Default or Event
of Default under this Indenture, except a default in the payment of the
principal of (and premium, if any) or interest on any Note, or in respect of a
covenant or provision that under this Indenture cannot be modified or amended
without the consent of the Holder of each Note outstanding.

         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 Event of Default or impair any right consequent thereon.

SECTION 514. UNDERTAKING FOR COSTS.

         All parties to this Indenture agree, and each Holder of Securities of
any series 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, suffered or omitted by it as Trustee, the filing by any party
litigant in such suit of an undertaking to pay the costs of such suit, and that
such court may in its discretion assess reasonable costs, including reasonable
attorneys fees 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 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 the
Outstanding Securities of any series, or to any suit instituted by any Holder
for the enforcement of the payment of the principal of (or premium, if any) or
interest on Securities of any series on or after the respective Stated
Maturities expressed in such Security (or, in the case of redemption, on or
after the Redemption Date); provided that neither this Section 514 nor the Trust
Indenture Act shall be deemed to

                                       49
<PAGE>   55

authorize any court to require such an undertaking or to make such an assessment
in any suit instituted by the Company.

SECTION 515. WAIVER OF STAY OR EXTENSION LAWS.

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

                                   ARTICLE SIX
                                   THE TRUSTEE

SECTION 601. NOTICE OF DEFAULTS.

         If a Default or an Event of Default occurs with respect to the
Securities of any series and is continuing and is known to the Trustee, the
Trustee shall mail to all Holders of the Securities notice of the Default or
Event of Default within 90 days after the occurrence thereof. Except in the case
of a Default or an Event of Default in payment of principal of (and premium, if
any, on) or interest on any Securities, the Trustee may withhold the notice to
the Holders if a committee of its trust officers in good faith determines that
withholding such notice is in the interests of the Holders.

SECTION 602. CERTAIN RIGHTS OF TRUSTEE.

         Subject to the provisions of TIA Sections 315(a) through 315(d):

         (1) the Trustee may rely and shall be protected in acting or
refraining from acting upon any resolution, certificate, statement, instrument,

note, other evidence of indebtedness or other paper or document believed by it
to be genuine and to have been signed or presented by the proper party or
parties;

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

                                       50
<PAGE>   56

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

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

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

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

         (8) the Trustee shall not be liable for any action taken, suffered
or omitted by it in good faith and reasonably believed by it to be authorized or
within the discretion or rights or powers conferred upon it by this Indenture;
and the Trustee shall not be deemed to have notice of any Default or Event of
Default, except in the case of an event of default involving failures by the
Company to pay principal, premium, if any, or interest on the Securities, unless
a Responsible Officer of the Trustee has actual knowledge thereof or unless
written notice of any event which is in fact such a default is received by the
Trustee at the Corporate Trust Office of the Trustee, and such notice references
the Company, the Securities or this Indenture.

SECTION 603. TRUSTEE NOT RESPONSIBLE FOR RECITALS OR ISSUANCE OF SECURITIES.

         The recitals contained herein and in the Securities, except for the
Trustee's certificate of authentication, and in any coupons shall be taken as
the statements of the Company, and neither the Trustee nor any Authenticating
Agent assumes any responsibility for their correctness. The Trustee makes no
representations as to the validity or sufficiency of this Indenture or of the
Securities or coupons. The Trustee shall not be accountable for the use or
application by the Company of Securities or the proceeds thereof, except that
the Trustee represents that it is duly authorized to execute and deliver this
Indenture, authenticate the Securities and perform its obligations hereunder and
that the statements to be made by it in a Statement of Eligibility on Form T-1
supplied to the Company are true and accurate, subject to the qualifications set
forth

                                       51
<PAGE>   57

therein. Neither the Trustee nor any Authenticating Agent shall be accountable
for the use or application by the Company of Securities or the proceeds thereof.

SECTION 604. MAY HOLD SECURITIES.

         The Trustee, any Authenticating Agent, any Paying Agent, any Security
Registrar or any other agent of the Company or of the Trustee, in its individual
or any other capacity, may become the owner or pledgee of Securities and coupons
and, subject to TIA Sections 310(b) and 311, may otherwise deal with the Company
with the same rights it would have if it were not Trustee, Authenticating Agent,
Paying Agent, Security Registrar or such other agent. The Trustee is permitted
to engage in other transactions; provided, however, that if it acquires any
conflicting interest it must eliminate such conflict or resign.

SECTION 605. MONEY HELD IN TRUST.

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

SECTION 606. COMPENSATION AND REIMBURSEMENT.

         The Company agrees:

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

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

         (3) to indemnify each of the Trustee or any predecessor Trustee
(and their respective directors, officers, employees and agents) for, and to
hold it harmless against, any and all loss, damage, claim, liability or expense,
incurred without negligence or bad faith on its part, arising out of or in
connection with the acceptance or administration of this trust, including the
costs and expenses of defending itself against any claim or liability in
connection with the exercise or performance of any of its powers or duties
hereunder.

         The obligations of the Company under this Section to compensate the
Trustee, to pay or reimburse the Trustee for expenses, disbursements and
advances and to indemnify and hold harmless the Trustee shall constitute
additional indebtedness hereunder and shall survive the satisfaction and
discharge of this Indenture and the resignation or removal of the Trustee. As

                                       52
<PAGE>   58

security for the performance of such obligations of the Company, the Trustee
shall have a claim prior to the Securities 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, if any) or interest on particular Securities.

         When the Trustee incurs expenses or renders services in connection with
an Event of Default specified in Section 501(7) or (8), the expenses (including
the reasonable charges and expenses of its counsel) of and the compensation for
such services are intended to constitute expenses of administration under
Bankruptcy Law.

         The provisions of this Section shall survive the termination of this
Indenture.

SECTION 607. CORPORATE TRUSTEE REQUIRED; ELIGIBILITY; CONFLICTING INTERESTS.

         There shall be at all times a Trustee hereunder which shall be eligible
to act as Trustee under TIA Section 310(a)(1) and which shall have an office in
The City of New York, and shall have a combined capital and surplus of at least
$100,000,000. If the Trustee does not have an office in The City of New York,
the Trustee may appoint an agent in The City of New York reasonably acceptable
to the Company to conduct any activities which the Trustee may be required under
this Indenture to conduct in The City of New York. If such corporation publishes
reports of condition at least annually, pursuant to law or to the requirements
of federal, state, territorial or District of Columbia supervising or examining
authority, then for the purposes of this Section 607, the combined capital and
surplus of such corporation shall be deemed to be its combined capital and
surplus as set forth in its most recent report of condition so published. If at
any time the Trustee shall cease to be eligible in accordance with the
provisions of this Section 607, it shall resign immediately in the manner and
with the effect hereinafter specified in this Article.

SECTION 608. RESIGNATION AND REMOVAL; APPOINTMENT OF SUCCESSOR.

         (a) No resignation or removal of the Trustee and no appointment of
a successor Trustee pursuant to this Article shall become effective until the
acceptance of appointment by the successor Trustee under Section 609.

         (b) The Trustee may resign at any time with respect to the
Securities of one or more series by giving written notice thereof to the
Company. If the instrument of acceptance by a successor Trustee required by
Section 609 shall not have been delivered to the Trustee within 30 days after
the giving of such notice of resignation, the resigning Trustee may, at the
expense of the Company, petition any court of competent jurisdiction for the
appointment of a successor Trustee with respect to the Securities of such
series.

         (c) The Trustee may be removed at any time with respect to the
Securities of any series by Act of the Holders of not less than a majority in
principal amount of the Outstanding Securities of such series, delivered to the
Trustee and the Company. If an instrument of acceptance by a successor Trustee
shall not have been delivered to the Trustee within 30 days

                                       53
<PAGE>   59

after the giving of such notice of removal, the removed Trustee may, at the
expense of the Company, petition a court of competent jurisdiction for the
appointment of a successor Trustee.

         (d) If at any time;

             (1) the Trustee shall fail to comply with the provisions of TIA
Section 310(b) after written request therefor by the Company or by any Holder
who has been a bona fide Holder of a Security for at least six months, or

             (2) the Trustee shall cease to be eligible under Section 607 and
shall fail to resign after written request therefor by the Company or by any
Holder who has been a bona fide Holder of a Security for at least six months, or

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

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

         (e) If the Trustee shall resign, be removed or become incapable of
acting, or if a vacancy shall occur in the office of Trustee for any cause, with
respect to the Securities of one or more series, the Company, by a Board
Resolution, shall promptly appoint a successor Trustee or Trustees with respect
to the Securities of that or those series (it being understood that any such
successor Trustee may be appointed with respect to the Securities of one or more
or all of such series and that at any time there shall be only one Trustee with
respect to the Securities of any particular series). If, within one year after
such resignation, removal or incapability, or the occurrence of such vacancy, a
successor Trustee with respect to the Securities of any series shall be
appointed by Act of the Holders of a majority in principal amount of the
Outstanding Securities of such series delivered to the Company and the retiring
Trustee, the successor Trustee so appointed shall, forthwith upon its acceptance
of such appointment in accordance with Section 609, 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 within 30 days of resignation or
removal of the Trustee, no successor Trustee with respect to the Securities of
any series shall have been so appointed by the Company or the Holders and
accepted appointment in the manner hereinafter provided, any Holder who has been
a bona fide Holder of a Security of such series for at least six months may, 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.

                                       54
<PAGE>   60

         (f) The Company shall give notice of each resignation and each
removal of the Trustee with respect to the Securities of any series and each
appointment of a successor Trustee with respect to the Securities of any series
to the Holders of Securities of such series in the manner provided for in
Section 106. Each notice shall include the name of the successor Trustee with
respect to the Securities of such series and the address of its Corporate Trust
Office.

SECTION 609. ACCEPTANCE OF APPOINTMENT BY SUCCESSOR.

         (a) Every successor Trustee appointed hereunder shall execute,
acknowledge and deliver to the Company and to the retiring Trustee an instrument
accepting such appointment, and thereupon the resignation or removal of the
retiring Trustee shall become effective and such successor Trustee, without any
further act, deed or conveyance, shall become vested with all the rights,
powers, trusts and duties of the retiring Trustee; provided, however, that the
retiring Trustee shall continue to be entitled to the benefit of Section 606;
but, on the request of the Company or the successor Trustee, such retiring
Trustee shall, upon payment of its charges, execute and deliver an instrument
transferring to such successor Trustee all the rights, powers and trusts of the
retiring Trustee and shall duly assign, transfer and deliver to such successor
Trustee all property and money held by such retiring Trustee hereunder.

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

                                       55
<PAGE>   61

"Indenture" and "Securities" shall have the meanings specified in the provisos
to the respective definitions of those terms in Section 101 which contemplate
such situation.

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

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

SECTION 610. MERGER, CONVERSION, CONSOLIDATION OR SUCCESSION TO BUSINESS.

         Any corporation into which the Trustee may be merged or converted or
with which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
corporation succeeding to all or substantially all of the corporate trust
business of the Trustee, shall be the successor of the Trustee hereunder,
provided such corporation shall be otherwise qualified and eligible under this
Article, without the execution or filing of any paper or any further act on the
part of any of the parties hereto. In case any Securities shall have been
authenticated, but not delivered, by the Trustee then in office, any successor
by merger, conversion or consolidation to such authenticating Trustee may adopt
such authentication and deliver the Securities so authenticated with the same
effect as if such successor Trustee had itself authenticated such Securities. In
case any of the Securities shall not have been authenticated by such predecessor
Trustee, any successor Trustee may authenticate such Securities either in the
name of any predecessor hereunder or in the name of the successor Trustee. In
all such cases such certificates shall have the full force and effect which this
Indenture provides for the certificate of authentication of the Trustee;
provided, however, that the right to adopt the certificate of authentication of
any predecessor Trustee or to authenticate Securities in the name of any
predecessor Trustee shall apply only to its successor or successors by merger,
conversion or consolidation.

SECTION 611. APPOINTMENT OF AUTHENTICATING AGENT.

         At any time when any of the Securities remain Outstanding, the Trustee
may appoint an Authenticating Agent or Agents with respect to one or more series
of Securities which shall be authorized to act on behalf of the Trustee to
authenticate Securities of such series and the Trustee shall give written notice
of such appointment to all Holders of Securities of the series with respect to
which such Authenticating Agent will serve, in the manner provided for in
Section 106. 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. Any such appointment shall be evidenced
by an instrument in writing signed by a Responsible Officer of the Trustee, and
a copy of such instrument shall be promptly furnished to the Company. 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

                                       56
<PAGE>   62

Authenticating Agent shall be acceptable to the Company and shall at all times
be a corporation organized and doing business under the laws of the United
States of America, any state thereof or the District of Columbia, authorized
under such laws to act as Authenticating Agent, having a combined capital and
surplus of not less than $50,000,000 and subject to supervision or examination
by federal or state authority. If such corporation publishes reports of
condition at least annually, pursuant to law or to the requirements of said
supervising or examining authority, then for the purposes of this Section, the
combined capital and surplus of such corporation shall be deemed to be its
combined capital and surplus as set forth in its most recent report of condition
so published. If at any time an Authenticating Agent shall cease to be eligible
in accordance with the provisions of this Section, 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 the corporate agency or
corporate trust business of an Authenticating Agent, shall continue to be an
Authenticating Agent, provided such corporation shall be otherwise eligible
under this Section, without the execution or filing of any paper or any further
act on the part of the Trustee or the Authenticating Agent.

         An Authenticating Agent may resign at any time by giving written notice
thereof to the Trustee and to the Company. The Trustee may at any time terminate
the agency of an Authenticating Agent by giving written notice thereof to such
Authenticating Agent and to the Company. Upon receiving such a notice of
resignation or upon such a termination, or in case at any time such
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, the Trustee may appoint a successor Authenticating
Agent which shall be acceptable to the Company and shall give written notice of
such appointment to all Holders of Securities of the series with respect to
which such Authenticating Agent will serve, in the manner provided for in
Section 106. Any successor Authenticating Agent upon acceptance of its
appointment hereunder shall become vested with all the rights, powers and duties
of its predecessor hereunder, with like effect as if originally named as an
Authenticating Agent. No successor Authenticating Agent shall be appointed
unless eligible under the provisions of this Section.

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

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

         Dated:............

                                       57
<PAGE>   63

SECTION 1002. MAINTENANCE OF OFFICE OR AGENCY.

         If the Securities of a series are issuable only as Registered

Securities an office or agency where Securities of that series may be presented
or surrendered for payment, where Securities of that series may be surrendered
for registration of transfer or exchange, where Securities of that series that
are convertible or exchangeable may be surrendered for conversion or exchange,
as applicable and where notices and demands to or upon the Company in respect of
the Securities of that series and this Indenture may be served.

         If Securities of a series are issuable as Bearer Securities, the
Company will maintain (A) in The City of New York, an office or agency where any
Registered Securities of that series may be presented or surrendered for
payment, where any Registered Securities of that series may be surrendered for
registration of transfer, where Securities of that series may be surrendered for
exchange, where Securities of that series that are convertible or exchangeable
may be surrendered for conversion or exchange, as applicable, where notices and
demands to or upon the Company in respect of the Securities of that series and
this Indenture may be served and where Bearer Securities of that series and

described in the following paragraph (and not otherwise), (B) subject to any
laws or regulations applicable thereto, in a Place of Payment for that series
which is located outside the United States, an office or agency where Securities
of that series and related coupons may be presented and surrendered for payment;
provided, however, that, if the Securities of that series are listed on any
stock exchange located outside the United States and such stock exchange shall
so require, the Company will maintain a Paying Agent for the Securities of that
series in any required city located outside the United States so long as the
Securities of that series are listed on such exchange, and (C) subject to any
laws or regulations applicable thereto, in a Place of Payment for that series
located outside the United States an office or agency where any Registered

Securities of that series may be surrendered for exchange, where Securities of
that series that are convertible and exchangeable may be surrendered for
conversion or exchange, as applicable and where notices and demands to or upon
the Company in respect of the Securities of that series and this Indenture may

         The Company will give prompt written notice to the Trustee of the

time the Company shall fail to maintain any such required office or agency or
shall fail to furnish the Trustee with the address thereof, such presentations,
surrenders, notices and demands may be made or served at the Corporate Trust
Office of the Trustee, except that Bearer Securities of any series and the

States; provided, however, that, if the Securities of a series are payable in
Dollars, payment of principal of (and premium, if any) and interest, if any, on
any Bearer Security shall be made at the office of the Company's Paying Agent in
The City of New York, if (but only if) payment in Dollars of the full amount of
such principal, premium or interest, as the case may be, at all offices or
agencies 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
any such designation; 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 accordance with the requirements set forth above for Securities of
any series for such purposes. The Company will 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 specified with respect to

Securities, the Company hereby designates as a Place of Payment for each series
of Securities the office or agency of the Company in the Borough of Manhattan.

Office as Paying Agent in such city and as its agent to receive all such
presentations, surrenders, notices and demands.

         Unless otherwise specified with respect to any Securities pursuant to
Section 301, if and so long as the Securities of any series may be payable in a
Currency other than Dollars, or so long as it is required under any other
provision of the 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 1003. 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 and any related coupons, it will, on or
before each due date of the principal of (or premium, if any) or interest, if
any, on any of the Securities of that series, segregate and hold in trust for
the benefit of the Persons entitled thereto a sum in the Currency in which the
Securities of such series are payable (except as otherwise specified pursuant to
Section 301 for the Securities of such series and except, if applicable, as
provided in Sections 313(b), 313(d) and 313(e)) sufficient to pay the principal
of (or premium, if any) or interest, if any, on Securities of such series so
becoming due until such sums shall be paid to such Persons or otherwise disposed
of as herein provided and will promptly notify the Trustee of its action or
failure so to act.

series of Securities and any related coupons, it will, prior to or on each due
date of the principal of (or premium, if any) or interest, if any, on any
Securities of that series, deposit with a Paying Agent a sum (in the Currency

premium, if any) or interest, if any, so becoming due, such sum to be held in
trust for the benefit

                                       65
<PAGE>   71

of the Persons entitled to such principal, premium or interest, 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 will cause each Paying Agent (other than the Trustee) for
any series of Securities to execute and deliver to the Trustee an instrument in
which such Paying Agent shall agree with the Trustee, subject to the provisions
of this Section, that such Paying Agent will:

         (1) hold all sums held by it for the payment of the principal of
(and premium, if any) and interest, if any, on 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 herein provided;

         (2) give the Trustee notice of any default by the Company (or any
other obligor upon the Securities of such series) in the making of any payment
of principal of (or premium, if any) or interest, if any, on 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 trusts as those upon which 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 provided in the Securities of any series, any money deposited
with the Trustee or any Paying Agent, or then held by the Company, in trust for
the payment of the principal of (or premium, if any) or interest, if any, on any
Security of any series, or any coupon appertaining thereto, and remaining
unclaimed for two years after such principal, premium or interest has become due
and payable shall be paid to the Company on Company Request, or (if then held by
the Company) shall be discharged from such trust; and the Holder of such
Security or coupon 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, may at
the expense of the Company cause to be published once, in an Authorized
Newspaper, notice that such money remains unclaimed and that, after a date
specified therein, which shall not be less than 30 days from the date of such
publication, any unclaimed balance of such money then remaining will be repaid
to the Company.

SECTION 1004. 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 that of each Restricted Subsidiary and the corporate rights
(charter and statutory), licenses and franchises of the Company and each
Restricted Subsidiary; provided, however, that the Company shall not be

                                       66
<PAGE>   72

required to preserve any such existence (except of the Company), right, license
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 each of its Restricted Subsidiaries, taken as a whole.

SECTION 1005. PAYMENT OF TAXES AND OTHER CLAIMS.

         The Company shall pay or discharge or cause to be paid or discharged,
before the same shall become delinquent, all material taxes, assessments and
governmental charges levied or imposed upon the Company or any Restricted

Restricted Subsidiary; provided, however, that the Company shall not be required
to pay or discharge or cause to be paid or discharged any such tax, assessment
or charge whose amount, applicability or validity is being contested in good
faith by appropriate proceedings.

         Securities of any series which are redeemable before their Stated
Maturity shall be redeemable in accordance with the terms of such Securities and
(except as otherwise specified as contemplated by Section 301 for Securities of
any series) in accordance with this Article.

SECTION 1102. ELECTION TO REDEEM; NOTICE TO TRUSTEE.

         The election of the Company to redeem any Securities shall be evidenced
by or pursuant to a Board Resolution. In case of any redemption at the election
of the Company, the Company shall, at least 60 days prior to the Redemption Date
fixed by the Company (unless a shorter notice shall be satisfactory to the
Trustee), notify the Trustee of such Redemption Date and of the principal amount
of Securities of such series to be redeemed and shall deliver to the Trustee

                                       67
<PAGE>   73

such documentation and records as shall enable the Trustee to select the
Securities to be redeemed pursuant to Section 1103. In the case of any
redemption of Securities prior to the expiration of any restriction on such
redemption provided in the terms of such Securities or elsewhere in this
Indenture, the Company shall furnish the Trustee with an Officers' Certificate
evidencing compliance with such restriction.

SECTION 1103. SELECTION BY TRUSTEE OF SECURITIES TO BE REDEEMED.

         If less than all the Securities of any series are to be redeemed, the
particular Securities to be redeemed shall be selected not more than 60 days
prior to the Redemption Date by the Trustee, from the Outstanding Securities of
such series not previously called for redemption, by such method as the Trustee
shall deem fair and appropriate and which may provide for the selection for
redemption of portions of the principal of Securities of such series; provided,
however, that no such partial redemption shall reduce the portion of the
principal amount of a Security not redeemed to less than the minimum authorized
denomination for Securities of such series established pursuant to Section 301.

         The Trustee shall promptly notify the Company 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 Security redeemed or to be redeemed only in part, to the
portion of the principal amount of such Security which has been or is to be
redeemed.

SECTION 1104. NOTICE OF REDEMPTION.

         Except as otherwise specified as contemplated by Section 301, notice of
redemption shall be given in the manner provided for in Section 106 not less
than 30 nor more than 60 days prior to the Redemption Date, to each Holder of
Securities to be redeemed.

         All notices of redemption shall identify the Securities (including
CUSIP number, if any) to be redeemed and shall state:

         (1) the Redemption Date,

         (2) the Redemption Price and the amount of accrued interest to the
Redemption Date payable as provided in Section 1106, if any,

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

         (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,

                                       68
<PAGE>   74

the holder 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 and accrued
interest, if any, to the Redemption Date payable as provided in Section 1106
will become due and payable upon each such Security, or the portion thereof, to
be redeemed and, if applicable, that interest thereon will cease to accrue on
and after said date,

         (6) the Place or Places of Payment 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 accrued interest, if any,

         (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 Redemption Date 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 any
Registered Securities of such series are not to be redeemed, and if such Bearer
Securities may be exchanged for Registered Securities not subject to redemption
on such Redemption Date pursuant to Section 306 or otherwise, the last date, as
determined by the Company, on which such exchanges may be made; and

         (10) if applicable, the Conversion Price, the date on which the
right to convert the principal of the Securities or the portions thereof to be
redeemed will terminate and the place or places where such Securities may be
surrendered for conversion.

         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 1105. DEPOSIT OF REDEMPTION PRICE.

         The Company shall deposit with the Trustee or with a Paying Agent (or,
if the Company is acting as its own Paying Agent, segregate and hold in trust as
provided in Section 1003) on or prior to the Redemption Date an amount of money
in the Currency in which the Securities of such series are payable (except as
otherwise specified pursuant to Section 301 for the Securities of such series
and except, if applicable, as provided in Sections 313(b), 313(d) and 313(e))
sufficient to pay the Redemption Price of, and accrued interest, if any, on, all
the Securities which are to be redeemed on that date.

                                       69
<PAGE>   75

SECTION 1106. 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 in the Currency in which the Securities of
such series are payable (except as otherwise specified pursuant to Section 301
for the Securities of such series and except, if applicable, as provided in
Sections 313(b), 313(d) and 313(e)) (together with accrued interest, if any, to
the Redemption Date), and from and after such date (unless the Company shall
default in the payment of the Redemption Price and accrued interest, if any)
such Securities shall, if the same were interest-bearing, 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 accrued interest, if any, to the Redemption Date; provided, however, that
installments of interest on Bearer Securities whose Stated Maturity is on or
prior to the Redemption Date shall be payable only at an office or agency
located outside the United States (except as otherwise provided in Section 1002)
and, unless otherwise specified as contemplated by Section 301, only upon
presentation and surrender of coupons for such interest; and provided further
that 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 relevant Record Dates according to their terms and the
provisions of Section 308.

         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 interest represented by coupons shall be payable only at an office
or agency located outside the United States (except as otherwise provided in
Section 1002) and, unless otherwise specified as contemplated by Section 301,
only upon presentation and surrender of those coupons.

         If any Security called for redemption shall not be so paid upon
surrender thereof for redemption, the principal (and premium, if any) shall,
until paid, bear interest from the Redemption Date at the rate of interest or
Yield to Maturity (in the case of Original Issue Discount Securities) set forth
in such Security.

<PAGE>   76

SECTION 1107. SECURITIES REDEEMED IN PART.

         Any Security which is to be redeemed only in part (pursuant to the
provisions of this Article or of Article Twelve) shall be surrendered at a Place
of Payment therefor (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 such Holder's
attorney duly authorized in writing), and the Company shall execute, and the
Trustee shall authenticate and deliver to the Holder of such Security without
service charge, a new Security or Securities of the same series, of any
authorized denomination as requested by such Holder, in aggregate principal
amount equal to and in exchange for the unredeemed portion of the principal of
the Security so surrendered.

                                 ARTICLE TWELVE
                                  SINKING FUNDS

SECTION 1201. APPLICABILITY OF ARTICLE.

         Retirements of Securities of any series pursuant to any sinking fund
shall be made in accordance with the terms of such Securities and (except as
otherwise specified as contemplated by Section 301 for Securities of any series)
in accordance with this Article.

         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 any 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 mandatory sinking fund payment may be subject to
reduction as provided in Section 1202. 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.

SECTION 1202. SATISFACTION OF SINKING FUND PAYMENTS WITH SECURITIES.

         Subject to Section 1203, in lieu of making all or any part of any
mandatory sinking fund payment with respect to any Securities of a series in
cash, the Company may at its option (1) deliver to the Trustee Outstanding
Securities of a series (other than any previously called for redemption)
theretofore purchased or otherwise acquired by the Company together in the case
of any Bearer Securities of such series with all unmatured coupons appertaining
thereto, and/or (2) receive credit for the principal amount of Securities of
such series which have been previously delivered to the Trustee by the Company
or for Securities of such series which have been redeemed either at the election
of the Company pursuant to the terms of such Securities or through the
application of permitted optional sinking fund payments pursuant to the terms of
such Securities, in each case in satisfaction of all or any part of any
mandatory sinking fund payment with respect to the Securities of the same series
required to be made pursuant to the terms of such Securities as provided for by
the terms of such series; provided, however, that such 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

                                       71
<PAGE>   77

redemption through operation of the sinking fund and the amount of such
mandatory sinking fund payment shall be reduced accordingly.

SECTION 1203. REDEMPTION OF SECURITIES FOR SINKING FUND.

         Not less than 60 days prior to each sinking fund payment date for any
series of Securities, the Company will deliver to the Trustee an Officers'
Certificate specifying the amount of the next ensuing 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 in the Currency in which the
Securities of such series are payable (except as otherwise specified pursuant to
Section 301 for the Securities of such series and except, if applicable, as
provided in Sections 313(b), 313(d) and 313(e)) and the portion thereof, if any,
which is to be satisfied by delivering or crediting Securities of that series
pursuant to Section 1202 (which Securities will, if not previously delivered,
accompany such certificate) and whether the Company intends to exercise its
right to make a permitted optional sinking fund payment with respect to such
series. Such certificate shall be irrevocable and upon its delivery the Company
shall be obligated to make the cash payment or payments therein referred to, if
any, on or before the next succeeding sinking fund payment date. In the case of
the failure of the Company to deliver such certificate, the sinking fund payment
due on the next succeeding sinking fund payment date for that series shall be
paid entirely in cash and shall be sufficient to redeem the principal amount of
such Securities subject to a mandatory sinking fund payment without the option
to deliver or credit Securities as provided in Section 1202 and without the
right to make any optional sinking fund payment, if any, with respect to such
series.

         Not more 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 1103 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 1104. Such notice having been duly given, the
redemption of such Securities shall be made upon the terms and in the manner
stated in Sections 1106 and 1107.

         On or prior to any sinking fund payment date, the Company shall pay to
the Trustee or a Paying Agent (or, if the Company is acting as its own Paying
Agent, segregate and hold in trust as provided in Section 1003) in cash a sum
equal to any interest that will accrue to the date fixed for redemption of
Securities or portions thereof to be redeemed on such sinking fund payment date
pursuant to this Section 1203.

         Notwithstanding the foregoing, with respect to a sinking fund for any
series of Securities, if at any time the amount of cash to be paid into such
sinking fund on the next succeeding sinking fund payment date, together with any
unused balance of any preceding sinking fund payment or payments for such
series, does not exceed in the aggregate $100,000, the Trustee, unless requested
by the Company, shall not give the next succeeding notice of the redemption of
Securities of such series through the operation of the sinking fund. Any such
unused balance of moneys deposited in such sinking fund shall be added to the
sinking fund payment for such series to be made in cash on the next succeeding
sinking fund payment date or, at the written request of the Company, shall be
applied at any time or from time to time to the purchase of

                                       72
<PAGE>   78

Securities of such series, by public or private purchase, in the open market or
otherwise, at a purchase price for such Securities (excluding accrued interest
and brokerage commissions, for which the Trustee or any Paying Agent will be
promptly reimbursed by the Company) not in excess of the principal amount
thereof.

                                ARTICLE THIRTEEN
                          PURCHASE AT OPTION OF HOLDERS

SECTION 1301. APPLICABILITY OF ARTICLE.

         Purchase by the Company of Securities of any series before their Stated
Maturity at the option of Holders thereof shall be made in accordance with the
terms of such Securities and (except as otherwise specified as contemplated by
Section 301 for Securities of any series) in accordance with this Article.

SECTION 1302. PURCHASE OF SECURITIES.

         Securities of any series subject to purchase in whole or in part at the
option of the Holders thereof will, unless otherwise provided in the terms of
such Securities, be purchased at a price equal to the principal amount thereof,
together with interest, if any, thereon accrued to the Purchase Date specified
in or pursuant to the terms of such Securities. The Company covenants that on or
before the Purchase Date it will deposit with the Trustee or with a Paying Agent
(or, if the Company is acting as its own Paying Agent, segregate and hold in
trust as provided in Section 1003) an amount of money in the Currency in which
the Securities of such series are payable (except as otherwise specified
pursuant to Section 301 for the Securities of such series and except, if
applicable, as provided in Sections 313(b), 313(d) and 313(e)) sufficient to pay
the principal (or, if so provided by the terms of the Securities of any series,
a percentage of the principal) of and (except if the Purchase Date shall be an
Interest Payment Date) accrued interest, if any, on, all the Securities or
portions thereof, as the case may be, to be purchased on such date.

SECTION 1303. EXERCISE OF OPTION.

         Securities of any series subject to purchase at the option of the
Holders thereof will contain an "Option to Elect Purchase" form on the reverse
of such Securities. To be purchased at the option of the Holder, any Security so
providing for such purchase, with the "Option to Elect Purchase" form on the
reverse of such Security duly completed by the Holder (or by the Holder's
attorney duly authorized in writing), must be received by the Company at the
Place of Payment therefor specified in the terms of such Security (or at such
other place or places of which the Company shall from time to time notify the
Holders of such Securities) not earlier than 45 days nor later than 30 days
prior to the Purchase Date. If less than the entire principal amount of such
Security is to be purchased in accordance with the terms of such Security, the
principal amount of such Security to be purchased, in increments of the minimum
denomination for Securities of such series, and the denomination or
denominations of the Security or Securities to be issued to the Holder for the
portion of the principal amount of such Security surrendered that is not to be
purchased, must be specified. The principal amount of any Security providing for
purchase at the

                                       73
<PAGE>   79

option of the Holder thereof may not be purchased in part if, following such
purchase, the unpaid principal amount of such Security would be less than the
minimum authorized denomination of Securities of the series of which such
Security to be purchased is a part. Except as otherwise may be provided by the
terms of any Security providing for purchase at the option of the Holder
thereof, exercise of the purchase option by the Holder shall be irrevocable
unless waived by the Company.

SECTION 1304. WHEN SECURITIES PRESENTED FOR PURCHASE BECOME DUE AND PAYABLE.

         If Securities of any series providing for purchase at the option of the
Holders thereof shall have been surrendered as provided in this Article and as
provided by or pursuant to the terms of such Securities, such Securities or the
portions thereof, as the case may be, to be purchased shall become due and
payable and shall be paid by the Company on the Purchase Date therein specified,
and on and after such Purchase Date (unless the Company shall default in the
payment of such Securities on such Purchase Date) such Securities shall, if the
same were interest-bearing, cease to bear interest and the coupons for such
interest appertaining to any Bearer Securities so to be repaid, except to the
extent provided below, shall be void. Upon surrender of any such Security for
purchase in accordance with such provisions, together with all coupons, if any,
appertaining thereto maturing after the Purchase Date, the principal amount of
such Security so to be purchased shall be paid by the Company, together with
accrued interest, if any, to the Purchase Date; provided however, that coupons
whose Stated Maturity is on or prior to the Purchase Date shall be payable only
at an office or agency located outside the United States (except as otherwise
provided in Section 1002) and, unless otherwise specified pursuant to Section
301, only upon presentation and surrender of such coupons; and provided further
that, in the case of Registered Securities, installments of interest, if any,
whose Stated Maturity is on or prior to the Purchase Date shall be payable to
the Holders of such Securities, or one or more Predecessor Securities,
registered as such at the close of business on the relevant Record Dates
according to their terms and the provisions of Section 308.

         If any Bearer Security surrendered for purchase shall not be
accompanied by all appurtenant coupons maturing after the Purchase Date, such
Security may be paid after deducting from the amount payable therefor as
provided in Section 1302 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 amid 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 as provided in the preceding sentence, such Holder shall be entitled
to receive the amount so deducted; provided, however, that interest represented
by coupons shall be payable only at an office or agency located outside the
United States (except as otherwise provided in Section 1002) and, unless
otherwise specified as contemplated by Section 301, only upon presentation and
surrender of those coupons.

         If the principal amount of any Security surrendered for purchase shall
not be so purchased upon surrender thereof, such principal amount (together with
interest, if any, thereon

                                       74
<PAGE>   80

accrued to such Purchase Date) shall, until paid, bear interest from the
Purchase Date at the rate of interest or Yield to Maturity (in the case of
Original Issue Discount Securities) set forth in such Security.

SECTION 1305. SECURITIES PURCHASED IN PART.

         Upon surrender of any Registered Security which is to be purchased in
part only, the Company shall execute and the Trustee shall authenticate and
deliver to the Holder of such Security, without service charge and at the
expense of the Company, a new Registered Security or Securities of the same
series, of any authorized denomination specified by the Holder, in an aggregate
principal amount equal to and in exchange for the portion of the principal of
such Security so surrendered which is not to be purchased.

                                ARTICLE FOURTEEN
                       DEFEASANCE AND COVENANT DEFEASANCE

SECTION 1401. COMPANY'S OPTION TO EFFECT DEFEASANCE OR COVENANT DEFEASANCE.

         Except as otherwise specified as contemplated by Section 301 for
Securities of any series, the provisions of this Article Fourteen shall apply to
each series of Securities, and the Company may, at its option, effect defeasance
of the Securities of or within a series under Section 1402, or covenant
defeasance of or within a series under Section 1403 in accordance with the terms
of such Securities and in accordance with this Article.

SECTION 1402. DEFEASANCE AND DISCHARGE.

         Upon the Company's exercise of the above option applicable to this
Section 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 related coupons on the date the conditions set
forth in Section 1404 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 related coupons, which shall thereafter be deemed to be "Outstanding"
only for the purposes of Section 1405 and the other Sections of this Indenture
referred to in (A) and (B) below, and to have satisfied all its other
obligations under such Securities and any related coupons and this Indenture
insofar as such Securities and any related coupons 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: (A) the rights of Holders of such
Outstanding Securities and any related coupons to receive, solely from the trust
fund described in Section 1404 and as more fully set forth in such Section,
payments in respect of the principal of (and premium, if any) and interest, if
any, on such Securities and any related coupons when such payments are due, (B)
the Company's obligations with respect to such Securities under Sections 304,
305, 306, 1002 and 1003, (C) the rights, powers, trusts, duties and immunities
of the Trustee hereunder and (D) this Article Fourteen. Subject to compliance
with this Article Fourteen, the Company may exercise its option under this
Section 1402

                                       75
<PAGE>   81
notwithstanding the prior exercise of its option under Section 1403 with
respect to such Securities and any related coupons.

SECTION 1403. COVENANT DEFEASANCE.

         Upon the Company's exercise under Section 1401 of the option applicable
to this Section 1403 with respect to any Securities of or within a series, the
Company shall be released from its obligations under any covenant under Article
Eight and in Sections 1004 through 1008, and, if specified pursuant to Section
301, its obligations under any other covenant, with respect to such Outstanding
Securities and any related coupons on and after the date the conditions set
forth in Section 1404 are satisfied (hereinafter, "Covenant Defeasance"), and
such Securities and any related coupons 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 such
covenants, but shall continue to be deemed "Outstanding" for all other purposes
hereunder (it being understood that such Securities shall not be deemed
Outstanding for financial accounting purposes). For this purpose, such covenant
defeasance means that, with respect to such Outstanding Securities and any
related coupons, 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 covenant,
whether directly or indirectly, by reason of any reference elsewhere herein to
any such covenant or by reason of reference in any such 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 501(4) or Section
501(9) or otherwise, as the case may be, but, except as specified in this
Section, the remainder of this Indenture and such Securities and any related
coupons shall be unaffected thereby. In addition, upon the Company's exercise
under Section 1401 of the option applicable to Section 1403, Sections 501(4)
through 501(6) shall not constitute Events of Default.

SECTION 1404. CONDITIONS TO DEFEASANCE OR COVENANT DEFEASANCE.

         The following shall be the conditions to application of either Section
1402 or Section 1403 to any Outstanding Securities of or within a series and any
related coupons:

         (1) The Company shall irrevocably have deposited or caused to be
deposited with the Trustee (or another trustee satisfying the requirements of
Section 607 who shall agree to comply with the provisions of this Article
Fourteen 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 related coupons, (A)
money (in Dollars or in the Foreign Currency in which the applicable series of
Securities is payable) in an amount, or (B) Government Obligations applicable to
such Securities 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, under such Securities and any related coupons, money (in
Dollars or in the Foreign Currency in which the applicable series of Securities
is payable) in an amount, or (C) a combination thereof, sufficient, in the
opinion of a nationally recognized firm of independent public accountants
expressed in a written certification thereof delivered to the Trustee, to pay
and discharge, and which shall be applied by the Trustee (or other qualifying
trustee) to pay and

                                       76
<PAGE>   82

discharge, (i) the principal of (and premium, if any) and interest, if any, on
such Outstanding Securities and any related coupons on the Stated Maturity (or
Redemption Date, if applicable) of such principal (and premium, if any) or
installment of interest, if any, and (ii) any mandatory sinking fund payments or
analogous payments applicable to such Outstanding Securities and any related
coupons on the day on which such payments are due and payable in accordance with
the terms of this Indenture and of such Securities and any related coupons;
provided that the Trustee shall have been irrevocably instructed to apply such
money or the proceeds of such Government Obligations to said payments with
respect to such Securities and any related coupons. Before such a deposit, the
Company may give to the Trustee, in accordance with Section 1102 hereof, a
notice of its election to redeem all or any portion of such Outstanding
Securities at a future date in accordance with the terms of the Securities of
such series and Article Eleven hereof, which notice shall be irrevocable. Such
irrevocable redemption notice, if given, shall be given effect in applying the
foregoing.

         (2) No Default or Event of Default with respect to such Securities
or any related coupons shall have occurred and be continuing on the date of such
deposit or, insofar as paragraphs (7) and (8) of Section 501 are concerned, at
any time during the period ending on the 91st day after the date of such deposit
(it being understood that this condition shall not be deemed satisfied until the
expiration of such period).

         (3) No event or condition shall exist that would prevent the
Company from making payments of the principal of (and premium, if any) or
interest on the Securities on the date of such deposit or at any time during the
period ending on the 91st day after the date of such deposit (it being
understood that this condition shall not be deemed satisfied until the
expiration of such period).

         (4) 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 or cause the Trustee or the trust so created to be subject to
the Investment Company Act of 1940, as amended.

         (5) In the case of an election under Section 1402, the Company
shall have delivered to the Trustee an Opinion of Counsel stating that (x) the
Company has received from, or there has been published by, the Internal Revenue
Service a ruling, or (y) 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 related coupons 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.

         (6) In the case of an election under Section 1403, the Company
shall have delivered to the Trustee an Opinion of Counsel to the effect that the
Holders of such Outstanding Securities and any related coupons 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

                                       77
<PAGE>   83

amounts, in the same manner and at the same times as would have been the case if
such covenant defeasance had not occurred.

         (7) In the case of an election under either Section 1402 or 1403,
the Company shall represent to the Trustee that the deposit made by the Company
pursuant to its election under Section 1402 or 1403 was not made by the Company
with the intent of preferring the Holders of Securities of any series over other
creditors of the Company or with the intent of defeating, hindering, delaying or
defrauding creditors of the Company or others.

         (8) Notwithstanding any other provisions of this Section, such
defeasance or covenant defeasance shall be effected in compliance with any
additional or substitute terms, conditions or limitations in connection
therewith pursuant to Section 301.

         (9) The Company shall have delivered to the Trustee an Officers'
Certificate and an Opinion of Counsel, each stating that all conditions
precedent provided for relating to either the defeasance under Section 1402 or
the covenant defeasance under Section 1403 (as the case may be) have been
complied with.

SECTION 1405. DEPOSITED MONEY AND GOVERNMENT OBLIGATIONS TO BE HELD IN TRUST;
OTHER MISCELLANEOUS PROVISIONS.

         Subject to the provisions of the last paragraph of Section 1003, all
money and Government Obligations (or other property as may be provided pursuant
to Section 301) (including the proceeds thereof) deposited with the Trustee (or
other qualifying trustee, collectively for purposes of this Section 1405, the
"Trustee") pursuant to Section 1404 in respect of such Outstanding Securities
and any related coupons shall be held in trust and applied by the Trustee, in
accordance with the provisions of such Securities and any related coupons 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 related coupons of all sums
due and to become due thereon in respect of principal (and premium, if any) and
interest, if any, but such money need not be segregated from other funds except
to the extent required by law.

         Unless otherwise specified with respect to any Security pursuant to
Section 301, if, after a deposit referred to in Section 1404(1) 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 313(b) or the terms of such
Security to receive payment in a Currency other than that in which the deposit
pursuant to Section 1404(1) has been made in respect of such Security, or (b) a
Currency Conversion Event occurs as contemplated in Section 313(d) or 313(e) or
by the terms of any Security in respect of which the deposit pursuant to Section
1404(1) has been made, the indebtedness represented by such Security and any
related coupons 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 such Security as they become 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 Currency Conversion Event based on

                                       78
<PAGE>   84

the applicable Market Exchange Rate for such Currency in effect on the third
Business Day prior to each payment date, except, with respect to a Currency
Conversion Event, for such Currency in effect (as nearly as feasible) at the
time of the Currency Conversion Event.

         The Company shall pay and indemnify the Trustee against any tax, fee or
other charge imposed on or assessed against the Government Obligations deposited
pursuant to Section 1404 or the principal and 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 related coupons.

         Anything in this Article Fourteen 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 Section 1404 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 an
equivalent defeasance or covenant defeasance, as applicable, in accordance with
this Article.

SECTION 1406. REINSTATEMENT.

         If the Trustee or any Paying Agent is unable to apply any money in
accordance with Section 1405 by reason of any order or judgment of any court or
governmental authority enjoining, restraining or otherwise prohibiting such
application, then the Company's obligations under this Indenture and such
Securities and any related coupons shall be revived and reinstated as though no
deposit had occurred pursuant to Section 1402 or 1403, as the case may be, until
such time as the Trustee or Paying Agent is permitted to apply all such money in
accordance with Section 1405; provided, however, that if the Company makes any
payment of principal of (or premium, if any) or interest, if any, on any such
Security or any related coupon following the reinstatement of its obligations,
the Company shall be subrogated to the rights of the Holders of such Securities
and any related coupons to receive such payment from the money held by the
Trustee or Paying Agent.

                                 ARTICLE FIFTEEN
                           SUBORDINATION OF SECURITIES

SECTION 1501. SECURITIES SUBORDINATED TO SENIOR INDEBTEDNESS.

         Except as otherwise specified as contemplated by Section 301, the
following provisions shall apply to Securities of each series.

         The Company covenants and agrees, and each Holder of a Security of any
series or of any coupon appertaining thereto, by his acceptance of Securities of
any series, likewise covenants and agrees, that, to the extent and in the manner
hereinafter set forth in this Article Fifteen, the indebtedness represented by
the Securities of such series and the payment of the principal of (and premium,
if any) and interest on each and all of the Securities of such series

                                       79
<PAGE>   85
(but not amounts owing to the Trustee by the Company pursuant to Section 606
hereof) are hereby expressly made subordinate and subject in right of payment to
the prior payment in full of all Senior Indebtedness.

         This Article Fifteen shall constitute a continuing offer to all persons
who, in reliance upon such provisions, become holders of, or continue to hold,
Senior Indebtedness, and such provisions are made for the benefit of the holders
of Senior Indebtedness, and such holders are made obligees hereunder and they
and/or each of them may enforce such provisions.

SECTION 1502. PAYMENT OVER OF PROCEEDS UPON DISSOLUTION, ETC.

         In the event of any payment or distribution of assets of the Company
for the benefit of creditors, marshaling of assets or any bankruptcy, insolvency
or similar proceedings of the Company (each such event herein sometimes referred
to as a "Proceeding"), then except in connection with the consolidation or
merger of the Company or its liquidation or dissolution following the
conveyance, transfer or lease of its properties and assets substantially as an
entirety, upon the terms and conditions described in Article Eight, the holders
of Senior Indebtedness shall first be entitled to receive payment in full, in
cash or cash equivalents, of all amounts due or to become due on or in respect
of such Senior Indebtedness before the Holders of any Security of such series or
of any coupon appertaining thereto are entitled to receive any payment of
principal of , and premium, if any, or interest on the Securities or on account
of the purchase or redemption or other acquisition of Securities by the Company
("Securities Payment"), and the holders of Senior Indebtedness shall be entitled
to receive, for application to the payment thereof, any payment or distribution
of any kind or character, whether in cash, property or securities which may be
payable or deliverable in respect of the Securities in any such Proceeding.

         In the event that, notwithstanding the foregoing provisions of this
Section 1502, the Trustee or the Holder of any Security shall have received any
payment or distribution of assets of the Company of any kind or character,
whether in cash, property or securities, before all the Senior Indebtedness is
paid in full, then such payment or distribution, except for amounts subject to
the claim granted to the Trustee in Section 606 hereof, shall be held in trust
for the holders of Senior Indebtedness and shall be paid over or delivered
forthwith to the trustee in bankruptcy or other Person making payment or
distribution of assets of the Company for application to the payment of all the
Senior Indebtedness remaining unpaid, to the extent necessary to pay all the
Senior Indebtedness in full, after giving effect to any concurrent payment or
distribution to or for the holders of the Senior Indebtedness.

         For purposes of this Article Fifteen only, the words "any payment or
distribution of any kind or character" and "cash, property or securities" shall
not be deemed to include a payment or distribution of equity or subordinated
securities of the Company provided for by a plan of reorganization or
readjustment or of any other corporation provided for by such plan of
reorganization or readjustment that, in the case of subordinated securities, are
subordinated in right of payment to all then outstanding Senior Indebtedness to
at least the same extent as the Securities, as the case may be, are so
subordinated as provided in this Article Fifteen.

                                       80
<PAGE>   86

SECTION 1503. NO PAYMENT WHEN CERTAIN SENIOR INDEBTEDNESS IN DEFAULT.

         In the event that any Senior Payment Default (as defined below) shall
have occurred and be continuing, then no Securities Payment shall be made unless
and until such Senior Payment Default shall have been cured or waived or shall
have ceased to exist or all amounts then due and payable in respect of the
Senior Indebtedness or other obligations that are the subject of such Senior
Payment Default shall have been paid in full. For purposes hereof, a "Senior
Payment Default" shall be deemed to have occurred if (1) the principal of (or
premium, if any), or interest or other amounts on, Senior Indebtedness is not
paid when due and any applicable grace period with respect to such default has
ended and such default has not been cured or waived or ceased to exist, or (2)
the maturity of any Senior Indebtedness has been accelerated because of a
default.

         In the event that any Senior Nonmonetary Default (as defined below)
shall have occurred and be continuing, then, upon the receipt by the Company and
the Trustee of written notice of such Senior Nonmonetary Default from an
authorized Person on behalf of any holder of Designated Senior Indebtedness, no
Securities Payment shall be made during the period (the "Payment Blockage
Period") commencing on the date of receipt of such written notice (the "Blockage
Notice") and ending on the earliest of (i) the 180th day after the date of such
receipt of the Blockage Notice, (ii) the date, if any, on which the Designated
Senior Indebtedness to which such default relates is discharged or such default
is waived or otherwise cured and (iii) the date, if any, on which such Payment
Blockage Period shall have been terminated by written notice to the Company or
the Trustee from the Person who gave the Blockage Notice. Not more than one
Blockage Notice may be given in any consecutive 365-day period, irrespective of
the number of Senior Nonmonetary Defaults which occur during such period. No
Senior Nonmonetary Default that existed or was continuing on the date of
commencement of any Payment Blockage Period with respect to the Designated
Senior Indebtedness initiating such Payment Blockage Period shall be, or be
made, the basis for the commencement of a subsequent Payment Blockage Period
unless such Senior Nonmonetary Default shall have been cured or waived for a
period of not less than 90 consecutive days. For purposes hereof, "Senior
Nonmonetary Default" means the occurrence or existence of any event,
circumstance, condition or state of facts that, by the terms of any instrument
pursuant to which any Designated Senior Indebtedness is outstanding, permits one
or more holders of such Designated Senior Indebtedness (or a trustee or agent on
behalf of the holders thereof) to declare such Designated Senior Indebtedness
due and payable prior to the date on which it would otherwise become due and
payable, other than a Senior Payment Default.

         In the event that, notwithstanding the foregoing, the Company shall
make any payment to the Trustee or any Holder prohibited by the foregoing
provisions of this Section 1503, then except for the amounts subject to the
claim granted to the Trustee in Section 606, such payment shall be held in trust
for the holders of Senior Indebtedness and shall be paid over and delivered
forthwith to the holders of Senior Indebtedness remaining unpaid, to the extent
necessary to pay in full all the Senior Indebtedness.

                                       81
<PAGE>   87

SECTION 1504. PAYMENT PERMITTED IF NO DEFAULT.

         Nothing contained in this Article Fifteen or elsewhere in this
Indenture or in any of the Securities shall, at any time except during the
pendency of any Proceeding referred to in Section 1502 or under the conditions
described in Section 1503, prevent (a) the Company from making Securities
Payments, or (b) the application by the Trustee of any money deposited with it
hereunder to Securities Payments or the retention of such payment by the
Holders.

SECTION 1505. SUBROGATION TO RIGHTS OF HOLDERS OF SENIOR DEBT.

         Subject to the payment in full of all Senior Indebtedness, the rights
of the Holders of the Securities shall be subrogated to the rights of the
holders of such Senior Indebtedness to receive payments and distributions of
cash, property and securities applicable to the Senior Indebtedness until the
principal of (and premium, if any) and interest on the Securities shall be paid
in full. For purposes of such subrogation, no payments or distributions to the
holders of the Senior Indebtedness of any cash, property or securities to which
the Holders of the Securities or the Trustee would be entitled except for the
provisions of this Article Fifteen, and no payments over pursuant to the
provisions of this Article Fifteen to the holders of Senior Indebtedness by
Holders of the Securities or the Trustee, shall, as among the Company, its
creditors other than holders of Senior Indebtedness and the Holders of the
Securities, be deemed to be a payment or distribution by the Company to or on
account of the Senior Indebtedness. Neither the Holders of the Securities nor
the Trustee shall have any claim against the holders of the Senior Indebtedness
or the Credit Facility Agent for any impairment of the subrogation rights herein
granted arising out of any release of Liens securing the Senior Indebtedness.

SECTION 1506. PROVISIONS SOLELY TO DEFINE RELATIVE RIGHTS.

         The provisions of this Article Fifteen are and are intended solely for
the purpose of defining the relative rights of the Holders on the one hand and
the holders of Senior Indebtedness on the other hand. Nothing contained in this
Article Fifteen or elsewhere in this Indenture or in the Securities is intended
to or shall (a) impair, as among the Company, its creditors other than holders
of Senior Indebtedness and the Holders of the Securities, the obligation of the
Company, which is absolute and unconditional (and which, subject to the rights
under this Article Fifteen of the holders of Senior Indebtedness, is intended to
rank equally with all other general obligations of the Company) to pay to the
Holders of the Securities the principal of (and premium, if any) and interest on
the Securities as and when the same shall become due and payable in accordance
with their terms; or (b) affect the relative rights against the Company of the
Holders of the Securities and creditors of the Company other than the holders of
Senior Indebtedness; or (c) prevent the Trustee or the Holder of any Security
from exercising all remedies otherwise permitted by applicable law upon default
under this Indenture, subject to the rights, if any, under this Article Fifteen
of the holders of Senior Indebtedness to receive cash, property and securities
otherwise payable or deliverable to the Trustee or such Holders. The holders of
the Senior Indebtedness shall be entitled to enforce the provisions of this
Article Fifteen against the Company, the Holders of the Securities and the
Trustee.

                                       82
<PAGE>   88

SECTION 1507. TRUSTEE TO EFFECTUATE SUBORDINATION.

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

SECTION 1508. NO WAIVER OF SUBORDINATION PROVISIONS.

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

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

SECTION 1509. NOTICE TO TRUSTEE.

         The Company shall give prompt written notice to the Trustee of any fact
known to the Company which would prohibit the making of any payment to or by the
Trustee in respect of the Securities and of any subsequent cure or waiver
thereof. Notwithstanding the provisions of this Article Fifteen or any other
provision of this Indenture, the Trustee shall not be charged with knowledge of
the existence of any facts which would prohibit the making of any payment to or
by the Trustee in respect of the Securities, unless and until the Trustee shall
have received written notice thereof from the Company or a holder of Senior
Indebtedness or from any trustee or agent therefor; and, prior to the receipt of
any such written notice, the Trustee, subject to the provisions of the Trust
Indenture Act, shall be entitled in all respects to assume that no such facts
exist.

                                       83
<PAGE>   89

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

SECTION 1510. RELIANCE ON JUDICIAL ORDER OR CERTIFICATE OF LIQUIDATION AGENT.

         Upon any payment or distribution of assets of the Company referred to
in this Article Fifteen, the Trustee, subject to the provisions of the Trust
Indenture Act, and the Holders of the Securities shall be entitled to rely upon
any order or decree entered by any court of competent jurisdiction in a
Proceeding, or a certificate of the trustee in bankruptcy, receiver, liquidating
trustee, custodian, assignee for the benefit of creditors, agent or other Person
making such payment or distribution, delivered to the Trustee or to the Holders
of Securities, for the purpose of ascertaining the Persons entitled to
participate in such payment or distribution, the holders of the Senior
Indebtedness and other indebtedness of the Company, the amount thereof or
payable thereon, the amount or amounts paid or distributed thereon and all other
facts pertinent thereto or to this Article Fifteen.

SECTION 1511. TRUSTEE NOT FIDUCIARY FOR HOLDERS OF SENIOR DEBT.

         Except to the extent of its obligations under the penultimate paragraph
of Section 1502 and the last paragraph of Section 1503, the Trustee shall not be
deemed to owe any fiduciary duty to the holders of Senior Indebtedness and shall
not be liable to any such holders if it shall in good faith mistakenly pay over
or distribute to Holders of Securities or to the Company or to any other Person
cash, property or securities to which any holders of Senior Indebtedness shall
be entitled by virtue of this Article Fifteen or otherwise. The Trustee's duties
with respect to holders of Senior Indebtedness are limited to those specifically
set forth in this Indenture, and no implied covenants or obligations shall be
construed by any provision hereof.

SECTION 1512. RIGHTS OF TRUSTEE AS HOLDER OF SENIOR DEBT; PRESERVATION OF
TRUSTEE'S RIGHTS.

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

                                       84
<PAGE>   90

         Nothing in this Article Fifteen shall apply to claims of, or payments
to, the Trustee under or pursuant to Section 606.

SECTION 1513. APPLICABILITY TO PAYING AGENTS.

         In case at any time any Paying Agent other than the Trustee shall have
been appointed by the Company and be then acting hereunder, the term "Trustee"
as used in this Article Fifteen shall in such case (unless the context otherwise
requires) be construed as extending to and including such Paying Agent within
its meaning as fully for all intents and purposes as if such Paying Agent were
named in this Article Fifteen in addition to or in place of the Trustee;
provided, however, that this Section 1513 shall not apply to the Company or any
Affiliate of the Company if it or such Affiliate acts as Paying Agent.

SECTION 1514. DEFEASANCE OF THIS ARTICLE FIFTEEN.

         The subordination of the Securities provided by this Article Fifteen is
expressly made subject to the provisions for defeasance or covenant defeasance
in Article Twelve hereof and, anything herein to the contrary notwithstanding,
upon the effectiveness of any such defeasance or covenant defeasance, the
Securities then outstanding shall thereupon cease to be subordinated pursuant to
this Article Fifteen.

SECTION 1515. SUBORDINATION PROVISIONS CONTROLLING.

         Notwithstanding anything to the contrary contained in this Indenture,
to the extent that any provision in this Indenture (other than those contained
in Section 101) conflicts with any provision contained in Article Fifteen
(including the definitions of certain terms used in Article Fifteen) of this
Indenture, the provisions contained in Article Fifteen of this Indenture shall
govern and control.

SECTION 1516. ARTICLE FIFTEEN NOT TO PREVENT EVENTS OF DEFAULT.

         The failure to make a payment on account of principal of or interest on
the Securities by reason of any provision of this Article shall not be construed
as preventing the occurrence of an Event of Default under Section 501. Nothing
contained in this Article Fifteen shall limit the right of the Trustee or the
Holders of Securities of such series and the coupons, if any, appertaining
thereto, to take any action to accelerate the maturity of the Securities
pursuant to Section 502 or to pursue any rights or remedies hereunder; PROVIDED
that all Senior Indebtedness then or thereafter due or declared to be due shall
first be paid in full before such Holders or the Trustee are entitled to receive
any payment from the Company of principal of, or interest on, the Securities.

SECTION 1517. TRUSTEE'S COMPENSATION NOT PREJUDICED.

         Nothing in this Article shall apply to amounts due to the Trustee
pursuant to Section 606.

                                       85
<PAGE>   91

                                 ARTICLE SIXTEEN
                                   CONVERSION

SECTION 1601. CONVERSION PRIVILEGE

         It may be provided pursuant to Section 301 with respect to Registered
Securities of any series that Holders have the option to convert the principal
amount thereof (or any portion thereof that is an integral multiple of $1,000)
into fully paid and nonassessable shares of Common Stock during the time
specified for conversion of such series pursuant to Section 301. Unless
otherwise specified pursuant to Section 301, the number of shares of Common
Stock issuable upon conversion of a Security will be determined by dividing the
principal amount of the Security which is being converted by the conversion
price specified for such Security pursuant to Section 301 (the "Conversion
Price") in effect on the Conversion Date.

         Provisions of this Indenture that apply to the conversion of all of a
Security pursuant to Section 301 also apply to conversion of a portion of such
Security. A Holder of Securities which are convertible pursuant to Section 301
is not entitled to any rights of a holder of Common Stock until such Holder of
Securities has converted such Securities into Common Stock, and only to the
extent that such Securities are deemed to have been converted into Common Stock
under this Article Sixteen or any other provisions applicable to such Securities
pursuant to Section 301.

SECTION 1602. CONVERSION PROCEDURE

         Unless otherwise specified pursuant to Section 301, the following
procedures will apply to the conversion of Securities which are made convertible
pursuant to Section 301. To convert a Security, a Holder must satisfy the
requirements to conversion applicable to such Security established pursuant to
Section 301. The date on which the Holder satisfies all of those requirements is
the conversion date (the "Conversion Date"). As soon as practicable after the
Conversion Date, the Company will deliver to the Holder through the Conversion
Agent a certificate for the number of whole shares of Common Stock issuable upon
conversion and a check for any fractional share determined pursuant to Section
1603. The Person in whose name the certificate is registered shall become the
stockholder of record on the Conversion Date and, as of such date, such Person's
rights as a Holder with respect to the converted Security shall cease; provided,
however, that no surrender of a Security on any date when the stock transfer
books of the Company shall be closed shall be effective to constitute the Person
entitled to receive the shares of Common Stock upon such conversion as the
stockholder of record of such shares of Common Stock on such date, but such
surrender shall be effective to constitute the person entitled to receive such
shares of Common Stock as the stockholder of record thereof for all purposes at
the close of business on the next succeeding day on which such stock transfer
books are open; provided further, however, that such conversion shall be at the
Conversion Price in effect on the Conversion Date, as if the stock transfer
books of the Company had not been closed.

         Except as described in this paragraph or in the second paragraph of
Section 308, no payment or adjustment will be made for accrued and unpaid
interest on a converted Security or for dividends or distributions on shares of
Common Stock issued upon conversion of a Security.

                                       86
<PAGE>   92

If any Holder surrenders a Security for conversion after the close of business
on the Regular Record Date for the payment of an installment of interest and
prior to the opening of business on the next Interest Payment Date (such period
being referred to as the "Post Regular Record Date Period"), then,
notwithstanding such conversion, the interest payable on such Interest Payment
Date shall be paid to the Holder of such Security on such Regular Record Date.
Any Security surrendered for conversion during the Post Regular Record Date
Period (except for a Security called for redemption on a Redemption Date during
the such period) must be accompanied by payment in funds acceptable to the
Company of an amount equal to the interest payable on such Interest Payment Date
on the portion so converted. Securities which have been called for redemption on
a Redemption Date during the Post Regular Record Date Period and which are
surrendered for conversion during such period are not required to be accompanied
by such payment.

         If a Holder converts more than one Security at the same time, the
number of whole shares of Common Stock issuable upon the conversion shall be
based on the total principal amount of Securities converted.

         Upon surrender of a Security that is converted in part, the trustee
shall authenticate and issue to the Holder a new Security equal in principal
amount to the unconverted portion of the Security surrendered.

SECTION 1603. FRACTIONAL SHARES

         The Company will not issue fractional shares of Common Stock upon
conversion of a Security. In lieu thereof, the Company will pay an amount in
cash based upon the Daily Market Price of the Common Stock on the Trading Day
prior to the Conversion Date.

SECTION 1604. TAXES ON CONVERSION

         The issuance of certificates for shares of Common Stock upon the
conversion of a Security shall be made without charge to the converting Holder
for such certificates or for any tax in respect of the issuance of such
certificates, and such certificates shall be issued in the respective names of,
or in such names as may be directed by, the Holder or Holders of the converted
Securities; provided, however, that in the event that securities for shares of
Common Stock are to be issued in a name other than the name of the Holder of the
Security converted, such Security, when surrendered for conversion, shall be
accompanied by an instrument of transfer, in form satisfactory to the Company,
duly executed by the Holder thereof or his duly authorized attorney; and
provided further, however, that the Company shall not be required to pay any tax
which may be payable in respect of any transfer involved in the issuance and
delivery of any such certificates in a name other than that of the Holder of the
converted Security, and the Company shall not be required to issue or deliver
such certificates unless or until the Person or Persons requesting the issuance
thereof shall have paid to the Company the amount of such tax or shall have
established to the satisfaction of the Company that such tax has been paid or is
not payable.

<PAGE>   93

SECTION 1605. COMPANY TO PROVIDE STOCK

         The Company shall at all times reserve and keep available, free from
preemptive rights, out of its authorized but unissued Common Stock, solely for
the purpose of issuance upon conversion of Securities which are convertible into
Common Stock pursuant to Section 301, a sufficient number of shares of Common
Stock to permit the conversion of all of such outstanding Securities for shares
of Common Stock.

         All shares of Common Stock which may be issued upon conversion of the
Securities shall be duly authorized, validly issued, fully paid and
nonassessable when so issued.

SECTION 1606. ADJUSTMENT OF CONVERSION PRICE

         Unless otherwise specified pursuant to Section 301, the Conversion
Price applicable to each series of Securities which are convertible into Common
Stock pursuant to Section 301 will be subject to adjustment from time to time as
follows:

         (a) In case the Company shall (i) pay a dividend in shares of
Common Stock to holders of Common Stock, (ii) make a distribution in shares of
Common Stock to holders of Common Stock, (iii) subdivide its outstanding shares
of Common Stock into a greater number of shares of Common Stock, or (iv) combine
its outstanding shares of Common Stock into a smaller number of shares of Common
Stock, the Conversion Price in effect immediately prior to such action shall be
adjusted so that the Holder of any Security thereafter surrendered for
conversion shall be entitled to receive the number of shares of Common Stock
which he would have owned immediately following such action had such Securities
been converted immediately prior thereto. Any adjustment made pursuant to this
subsection (a) shall become effective immediately after the record date in the
case of a dividend or distribution and shall become effective immediately after
the effective date in the case of a subdivision or combination.

         (b) In case the Company shall issue rights or warrants to
substantially all holders of Common Stock entitling them (for a period
commencing no earlier than the record date for the determination of holders of
Common Stock entitled to receive such rights or warrants and expiring not more
than 45 days after such record date) to subscribe for or purchase shares of
Common Stock (or securities convertible into Common Stock) at a price per share
less than the Current Market Price (as determined pursuant to subsection (d)
below) of the Common Stock on such record date, the Conversion Price shall be
adjusted so that the same shall equal the price determined by multiplying the
Conversion Price in effect immediately prior to such record date by a fraction
of which the numerator shall be the number of shares of Common Stock outstanding
on such record date, plus the number of shares of Common Stock which the
aggregate offering price of the offered shares of Common Stock (or the aggregate
conversion price of the convertible securities so offered) would purchase at
such Current Market Price, and of which the denominator shall be the number of
shares of Common Stock outstanding on such record date plus the number of
additional shares of Common Stock offered (or into which the convertible
securities so offered are convertible). Such adjustments shall become effective
immediately after such record date.

                                       88
<PAGE>   94

         (c) In case the Company shall distribute to substantially all
holders of Common Stock shares of any class of Capital Stock of the Company
other than Common Stock, evidences of indebtedness or other assets (other than
cash dividends or distributions out of current or retained earnings), or shall
distribute to substantially all holders of Common Stock rights or warrants to
subscribe for securities (other than those securities referred to in subsection
(b) above), then in each such case the Conversion Price shall be adjusted so
that the same shall equal the price determined by multiplying the Conversion
Price in effect immediately prior to the date of such distribution by a fraction
of which the numerator shall be the Current Market Price (determined as provided
in subsection (d) below) of the Common stock on the record date mentioned below
less the then fair market value (as determined by the Board of Directors, whose
determination shall be conclusive evidence of such fair market value, and
described in a Board Resolution) of the portion of the assets so distributed in
respect of, or of such subscription rights or warrants applicable, to one share
of Common Stock, and of which the denominator shall be such Current Market Price
of the Common Stock. Such adjustment shall become effective immediately after
the record date for the determination of the holders of Common Stock entitled to
receive such distribution. Notwithstanding the foregoing, in case the Company
shall issue rights or warrants to subscribe for additional shares of the
Company's Capital Stock (other than those referred to in subsection (b) above)
("Rights") to substantially all holders of Common Stock, the Company may, in
lieu of making any adjustment pursuant to this Section 1606, make proper
provision so that each Holder of a Security who converts such Security (or any
portion thereof) after the record date for such distribution and prior to the
expiration or redemption of the Rights shall be entitled to receive upon such
conversion, in addition to the shares of Common Stock issuable upon such
conversion (the "Conversion Shares"), a number of Rights to be determined as
follows: (i) if such conversion occurs on or prior to the date for the
distribution to the holders of Rights of separate certificates evidencing such
Rights (the "Distribution Date"), the same number of Rights to which a holder of
a number of shares of Common Stock equal to the number of Conversion Shares is
entitled at the time of such conversion in accordance with the terms and
provisions of and applicable to the Rights; and (ii) if such conversion occurs
after the Distribution Date, the same number of Rights to which a holder of the
number of shares of Common Stock into which the principal amount of the Security
so converted was convertible immediately prior to the Distribution Date would
have been entitled on the Distribution Date in accordance with the terms and
provisions of and applicable to the Rights.

         (d) The "Current Market Price" per share of Common Stock on any
date shall be deemed to be the average of the Daily Market Prices for the
shorter of (i) 30 consecutive Business Days ending on the last full Trading Day
on the exchange or market referred to in determining such Daily Market Prices
prior to the time of determination or (ii) the period commencing on the date
next succeeding the first public announcement of the issuance of such rights or
such warrants or such other distribution through such last full Trading Day on
which the distribution of rights to purchase stock or securities or distribution
of securities convertible into or exchangeable for stock made by the Company to
its stockholders will not be taxable to the recipients thereof.

         (e) In any case in which this Section 1606 shall require that an
adjustment be made immediately following a record date for an event, the Company
may elect to defer, until such event, issuing to the Holder of any Security
converted after such record date the shares of

                                       89
<PAGE>   95

Common Stock and other Capital Stock of the Company issuable upon such
conversion over and above the shares of Common Stock and other Capital Stock of
the Company issuable upon such conversion only on the basis of the Conversion
Price prior to adjustment; and, in lieu of the shares the issuance of which is
so deferred, the Company shall issue or cause its transfer agents to issue due
bills or other appropriate evidence of the right to receive such shares.

SECTION 1607.  NO ADJUSTMENT

         No adjustment in the Conversion Price shall be required until
cumulative adjustments amount to 1% or more of the Conversion Price as last
adjusted; provided, however, that any adjustments which by reason of this
Section 1607 are not required to be made shall be carried forward and taken into
account in any subsequent adjustment. All calculations under this Article
Sixteen shall be made to the nearest cent (with $.005 being rounded upward) or
to the nearest one-hundredth of a share (with .005 of a share being rounded
upward), as the case may be. No adjustment need be made for rights to purchase
Common Stock pursuant to a Company plan for reinvestment of dividends or
interest. No adjustment need be made for a change in the par value or no par
value of the Common Stock.

SECTION 1608.  OTHER ADJUSTMENTS

         (a) Unless otherwise specified pursuant to Section 301, in the
event that, as a result of an adjustment made pursuant to Section 1606 above,
the Holder of any Security subject to conversion and thereafter surrendered for
conversion shall become entitled to receive any shares of Capital Stock of the
Company other than shares of Common Stock, thereafter the Conversion Price of
such other shares so receivable upon conversion of any Securities shall be
subject to adjustment from time to time in a manner and on terms as nearly
equivalent as practicable to the provisions with respect to Common Stock
contained in this Article Sixteen.

         (b) Unless otherwise specified pursuant to Section 301, in the
event that shares of Common Stock or the other securities are not delivered
after the expiration of any of the rights or warrants referred to in Section
1606(b) and Section 1606(c) hereof, the Conversion Price shall be readjusted to
the Conversion Price which would otherwise be in effect had the adjustment made
upon the issuance of such rights or warrants been made on the basis of delivery
of only the number of shares of Common Stock actually delivered.

SECTION 1609.  ADJUSTMENTS FOR TAX PURPOSES

         Unless otherwise specified pursuant to Section 301, the Company may, at
its option, make such reductions in the Conversion Price with respect to any
series of Securities subject to conversion, in addition to those required by
Section 1606 above, as it determines to be advisable in order that any stock
dividend, subdivision of shares, distribution of rights to purchase stock or
securities or distribution of securities convertible into or exchangeable for
stock made by the Company to its stockholders will not be taxable to the
recipients thereof.

                                       90
<PAGE>   96

SECTION 1610. ADJUSTMENTS BY THE COMPANY

         Unless otherwise specified in Section 301, the Company from time to
time may, to the extent permitted by law, reduce the Conversion Price with
respect to any series of Securities subject to conversion by any amount for any
period of at least 20 days, in which case the Company shall give at least 15
days' notice of such reduction in accordance with Section 1611, if the Board of
Directors has made a determination that such reduction would be in the best
interests of the Company, which determination shall be conclusive.

SECTION 1611. NOTICE OF ADJUSTMENT

         Whenever the Conversion Price with respect to any series of Securities
subject to conversion is adjusted, the Company shall promptly mail to Holders of
the Securities of such series at the addresses appearing on the Security
Register a notice of the adjustment and file with the Trustee an Officers'
Certificate briefly stating the facts requiring the adjustment and the manner of
computing it. The certificate shall be conclusive evidence of the correctness of
such adjustment.

SECTION 1612. NOTICE OF CERTAIN TRANSACTIONS

         In the event that:

         (1) the Company takes any action which would require an adjustment in
the Conversion Price;

         (2) the Company takes any action that would require a supplemental
indenture pursuant to Section 1613; or

         (3) there is a dissolution or liquidation of the Company;

a Holder of a Security that is subject to conversion pursuant to Section 301 may
wish to convert such Security into shares of Common Stock prior to the record
date for or the effective date of the transaction so that such Holder may
receive the rights, warrants, securities or assets which a holder of shares of
Common Stock on that date may receive. Therefore, the Company shall mail to
Holders of such Securities at the addresses appearing on the Security Register
and to the Trustee a notice stating the proposed record or effective date, as
the case may be. The Company shall mail the notice at least 15 days before such
date; however, failure to mail such notice or any defect therein shall not
affect the validity of any transaction referred to in clause (1), (2) or (3) of
this Section 1612.

SECTION 1613. EFFECT OF RECLASSIFICATIONS, CONSOLIDATIONS, MERGERS OR SALES ON
CONVERSION PRIVILEGE

         If any of the following shall occur (and on the date of such occurrence
there are Securities outstanding under this Indenture that are subject to
conversion pursuant to Section 301), namely: (i) any reclassification or change
of outstanding shares of Common Stock (other

                                       91
<PAGE>   97

than a change in par value, or from par value to no par value, or from no par
value to par value, or as a result of a subdivision or combination), (ii) any
consolidation or merger to which the Company is a party other than a merger in
which the Company is the continuing corporation and which does not result in any
reclassification of, or change (other than a change in name, or par value, or
from par value to no par value, or from no par value to par value or as a result
of a subdivision or combination) in, outstanding shares of Common Stock or (iii)
any sale or conveyance of all or substantially all of the property or business
of the Company as an entirety, then the Company, or such successor or purchasing
corporation, as the case may be, shall, as a condition precedent to such
reclassification, change, consolidation, merger, sale or conveyance, execute and
deliver to the Trustee a supplemental indenture in form satisfactory to the
Trustee providing that the Holder of each Security then outstanding (which is
subject to conversion pursuant to Section 301) shall have the right to convert
such Security into the kind and amount of shares of stock and other securities
and property (including cash) receivable upon such reclassification, change,
consolidation, merger, sale or conveyance by a holder of the number of shares of
Common Stock deliverable upon conversion of such Security immediately prior to
such reclassification, change, consolidation, merger, sale or conveyance. Such
supplemental indenture shall provide for adjustments of the Conversion Price
which shall be as nearly equivalent as may be practicable to the adjustments of
the Conversion Price provided for in this Article Sixteen. The foregoing,
however, shall not in any way affect the right a Holder of a Security may
otherwise have, pursuant to clause (ii) of the last sentence of subsection (c)
of Section 1601, to receive Rights upon conversion of a Security. If, in the
case of any such consolidation, merger, sale or conveyance, the stock or other
securities and property (including cash) receivable thereupon by a holder of
Common Stock includes shares of stock or other securities and property of a
corporation other than the successor or purchasing corporation, as the case may
be, in such consolidation, merger, sale or conveyance, then such supplemental
indenture shall also be executed by such other corporation and shall contain
such additional provisions to protect the interests of the Holders of the
Securities (which are subject to conversion pursuant to Section 301) as the
Board of Directors of the Company shall reasonably consider necessary by reason
of the foregoing. The provision of this Section 1613 shall similarly apply to
successive consolidations, mergers, sales or conveyances.

         In the event the Company shall execute a supplemental indenture
pursuant to this Section 1613, the Company shall promptly file with the Trustee
an Officers' Certificate briefly stating the reasons therefor, the kind or
amount of shares of stock or securities or property (including cash) receivable
by Holders of the Securities (which are subject to conversion pursuant to
Section 301) upon the conversion of their Securities after any such
reclassification, change, consolidation, merger, sale or conveyance and any
adjustment to be made with respect thereto.

SECTION 1614. TRUSTEE'S DISCLAIMER

         The Trustee has no duty to determine when an adjustment under this
Article Sixteen should be made, how it should be made or what such adjustment
should be, but may accept as conclusive evidence of the correctness of any such
adjustment, and shall be protected in relying upon the Officers' Certificate
with respect thereto which the Company is obligated to file with the Trustee
pursuant to Section 1611. The Trustee makes no representation as to the validity
or

                                       92
<PAGE>   98

value of any securities or assets issued upon conversion of Securities, and the
Trustee shall not be responsible for the Company's failure to comply with any
provisions of this Article Sixteen.

The Trustee shall not be under any responsibility to determine the correctness
of any provisions contained in any supplemental indenture executed pursuant to
Section 1613, but may accept as conclusive evidence of the correctness thereof,
and shall be protected in relying upon, the Officers' Certificate with respect
thereto which the Company is obligated to file with the Trustee pursuant to
Section 1613.

                        MEETINGS OF HOLDERS OF SECURITIES

SECTION 1701. PURPOSES FOR WHICH MEETINGS MAY BE CALLED.

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

SECTION 1702. CALL, NOTICE AND PLACE OF MEETINGS.

         (a) The Trustee may at any time call a meeting of Holders of
Securities of any series for any purpose specified in Section 1701, to be held
at such time and at such place in The City of New York or in London as the
Trustee shall determine. Notice of every meeting of Holders of Securities of any
series, setting forth the time and the place of such meeting and in general
terms the action proposed to be taken at such meeting, shall be given, in the
manner provided for in Section 106, not less than 21 nor more than 180 days
prior to the date fixed for the meeting.

         (b) In case at any time the Company, pursuant to a Board
Resolution, or the Holders of at least 10% in principal amount of the
Outstanding Securities of any series shall have requested the Trustee to call a
meeting of the Holders of Securities of such series for any purpose specified in
Section 1701, by written request setting forth in reasonable detail the action
proposed to be taken at the meeting, and the Trustee shall not have made the
first publication of the notice of such meeting within 21 days after receipt of
such request or shall not thereafter proceed to cause the meeting to be held as
provided herein, then the Company or the Holders of Securities of such series in
the amount above specified, as the case may be, may determine the time and the
place in The City of New York or [IN LONDON] for such meeting and may call such
meeting for such purposes by giving notice thereof as provided in paragraph (a)
of this Section.

SECTION 1703. PERSONS ENTITLED TO VOTE AT MEETINGS.

         To be entitled to vote at any meeting of Holders of Securities of any
series, a Person shall be (1) a Holder of one or more Outstanding Securities of
such series, or (2) a Person appointed by an instrument in writing as proxy for
a Holder or Holders of one or more Outstanding

                                       93
<PAGE>   99

Securities of such series by such Holder or Holders. The only Persons who shall
be entitled to be present or to speak at any meeting of Holders of Securities of
any series shall be the Person entitled to vote at such meeting and their
counsel, any representatives of the Trustee and its counsel and any
representatives of the Company and its counsel.

SECTION 1704. QUORUM; ACTION.

         The Persons entitled to vote a majority in principal amount of the
Outstanding Securities of a series shall constitute a quorum for a meeting of
Holders of Securities of such series; provided, however, that, if any action is
to be taken at such meeting with respect to a consent or waiver which this
Indenture expressly provides may be given by the Holders of not less than a
specified percentage in principal amount of the Outstanding Securities of a
series, the Persons entitled to vote such specified percentage in principal
amount of the Outstanding Securities of such series shall constitute a quorum.
In the absence of a quorum within 30 minutes of the time appointed for any such
meeting, the meeting shall, if convened at the request of Holders of Securities
of such series, be dissolved. In any other case the meeting may be adjourned for
a period of not less than 10 days as determined by the chairman of the meeting
prior to the adjournment of such meeting. In the absence of a quorum at any such
adjourned meeting, such adjourned meeting may be further adjourned for a period
of not less than 10 days as determined by the chairman of the meeting prior to
the adjournment of such adjourned meeting. Notice of the reconvening of any
adjourned meeting shall be given as provided in Section 1702(a), except that
such notice need be given only once not less than five days prior to the date on
which the meeting is scheduled to be reconvened. Notice of the reconvening of
any adjourned meeting shall state expressly the percentage, as provided above,
of the principal amount of the Outstanding Securities of such series which shall
constitute a quorum.

         Subject to the foregoing, at the reconvening of any meeting adjourned
for lack of a quorum the Persons entitled to vote 25% in principal amount of the
Outstanding Securities at the time shall constitute a quorum for the taking of
any action set forth in the notice of the original meeting.

         Except as limited by the proviso to Section 902, any resolution
presented to a meeting or adjourned meeting duly reconvened at which a quorum is
present as aforesaid may be adopted by the affirmative vote of the Holders of
not less than a majority in principal amount of the Outstanding Securities of
such series; provided however, that, except as limited by the proviso to Section
902, any resolution with respect to any request, demand, authorization,
direction, notice, consent, waiver or other action which this Indenture
expressly provides may be made, given or taken by the Holders of a specified
percentage, which is less than a majority, in principal amount of the
Outstanding Securities of a series may be adopted at a meeting or an adjourned
meeting duly reconvened and at which a quorum is present as aforesaid by the
affirmative vote of the Holders of not less than such specified percentage in
principal amount of the Outstanding Securities of such series.

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

                                       94
<PAGE>   100

         Notwithstanding the foregoing provisions of this Section 1704, if any
action is to be taken at a meeting of Holders of Securities of any series with
respect to any request, demand, authorization, direction, notice, consent,
waiver or other action that this Indenture expressly provides may be made, given
or taken by the Holders of a specified percentage in principal amount of all
Outstanding Securities affected thereby, or of the Holders of such series and
one or more additional series:

         (i) there shall be no minimum quorum requirement for such meeting; and

         (ii) the principal amount of the Outstanding Securities of such
series that vote in favor of such request, demand, authorization, direction,
notice, consent, waiver or other action shall be taken into account in
determining whether such request, demand, authorization, direction, notice,
consent, waiver or other action has been made, given or taken under this
Indenture.

SECTION 1705. DETERMINATION OF VOTING RIGHTS; CONDUCT AND ADJOURNMENT OF
MEETINGS.

         (a) Notwithstanding any provisions of this Indenture, the Trustee
may make such reasonable regulations as it may deem advisable for any meeting of
Holders of Securities of a series in regard to proof of the holding of
Securities of such series and of the appointment of proxies and in regard to the
appointment and duties of inspectors of votes, the submission and examination of
proxies, certificates and other evidence of the right to vote, and such other
matters concerning the conduct of the meeting as it shall deem appropriate.
Except as otherwise permitted or required by any such regulations, the holding
of Securities shall be proved in the manner specified in Section 104 and the
appointment of any proxy shall be proved in the manner specified in Section 104
or by having the signature of the person executing the proxy witnessed or
guaranteed by any trust company, bank or banker authorized by Section 104 to
certify to the holding of Bearer Securities. Such regulations may provide that
written instruments appointing proxies, regular on their face, may be presumed
valid and genuine without the proof specified in Section 104 or other proof.

         (b) 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 1702(b), in which
case the Company or the Holders of Securities of the series calling the meeting,
as the case may be, shall in like manner appoint a temporary chairman. A
permanent chairman and a permanent secretary of the meeting shall be elected by
vote of the Persons entitled to vote a majority in principal amount of the
Outstanding Securities of such series represented at the meeting.

         (c) At any meeting each Holder of a Security of such series or
proxy shall be entitled to one vote for each $1,000 principal amount of
Outstanding Securities of such series held or represented by him (determined as
specified in the definition of "Outstanding" in Section 101); provided, however,
that no vote shall be cast or counted at any meeting in respect of any Security
challenged as not Outstanding and ruled by the chairman of the meeting to be not
Outstanding.

                                       95
<PAGE>   101

The chairman of the meeting shall have no right to vote, except as a Holder of a
Security of such series or proxy.

         (d) Any meeting of Holders of Securities of any series duly called
pursuant to Section 1502 at which a quorum is present may be adjourned from time
to time by Persons entitled to vote a majority in principal amount of the
Outstanding Securities of such series represented at the meeting; and the
meeting may be held as so adjourned without further notice.

SECTION 1706. COUNTING VOTES AND RECORDING ACTION OF MEETINGS.

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