                                   ARTICLE ONE

                        DEFINITIONS AND OTHER PROVISIONS
                             OF GENERAL APPLICATION

                  SECTION 101. DEFINITIONS.

                  For all purposes of this Indenture, except as otherwise
expressly provided or unless the context otherwise requires:

                  (1) the terms defined in this Article have the meanings
         assigned to them in this Article, and include the plural as well as the
         singular;

                  (2) all other terms used herein which are defined in the Trust
         Indenture Act or by Commission rule or regulation under the Trust
         Indenture Act, either directly or by reference therein, as in force at
         the date as of which this instrument was executed, except as provided
         in Section 905, have the meanings assigned to them therein;

                  (3) all accounting terms not otherwise defined herein have the
         meanings assigned to them in accordance with GAAP; and

                  (4) the words "herein", "hereof" and "hereunder" and other
         words of similar import refer to this Indenture as a whole and not to
         any particular Article, Section or other subdivision.

<PAGE>

                  Certain terms, used principally in Article Six, are defined in
that Article.

                  "Act" when used with respect to any Holder has the meaning
specified in Section 104.

                  "Affiliate" of any specified Person means any other Person

common control with such specified Person. For the purposes of this definition,
"control" when used with respect to any specified Person means the power to

whether through the ownership of voting securities by contract or otherwise, and
the terms "controlling" and "controlled" have meanings correlative to the

such capital leases as determined under GAAP. The amount of attributable debt
relating to operating leases is the amount of future minimum lease payments
under such operating leases required to be disclosed by GAAP, less any executory
costs, discounted using the interest rate implicit in such lease to calculate
the present value of operating lease payments. "Executory costs" mean amounts
required to be paid on account of maintenance and repairs, insurance, taxes,
assessments, water rates and similar charges. In the case of any operating lease
which is terminable by the lessee upon the payment of a penalty, such net amount
shall include the lesser of (a) the rental payments to be paid under such lease
until the first date (after the date of such determination) upon which it may be
so terminated plus the then applicable penalty upon such termination, or (b) the
rental payments required to be paid during the remaining term of such lease
(assuming such termination provision is not exercised).

                  "Authenticating Agent" means any Person authorized by the

publications are required to be made in Authorized Newspapers, the successive
publications may be made in the same or in different newspapers in the same city
meeting the foregoing requirements and in each case on any Business Day.

                  "Company" means the Person named as the "Company" in the first
paragraph of this instrument until a successor Person shall have become such
pursuant to the applicable provisions of this Indenture, and thereafter
"Company" shall mean such successor Person.

application or request as to which the furnishing of such documents is
specifically required by any provision of this Indenture relating to such
particular application or request, no additional certificate or opinion need be
furnished.

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

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

<PAGE>

                  SECTION 103. FORM OF DOCUMENTS DELIVERED TO TRUSTEE.

                  In any case where several matters are required to be certified
by, or covered by an opinion of, any specified Person, it is not necessary that
all such matters be certified by, or covered by the opinion of, only one such
Person, or that they be so certified or covered by only one document, but one
such Person may certify or give an opinion with respect to some matters and one
or more other such Persons as to other matters, and any such Person may certify
or give an opinion as to such matters in one or several documents.

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

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

                  SECTION 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 may be embodied in and evidenced by one or more instruments of
substantially similar tenor signed by such Holders in person or by an agent duly
appointed in writing. If Debt Securities of a series are issuable in whole or in
part 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 may, alternatively, be embodied in and evidenced by the
record of Holders of Debt Securities voting in favor thereof, either in person
or by proxies duly appointed in writing, at any meeting of Holders of Debt
Securities duly called and held in accordance with the provisions of Article
Fourteen, 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 and so voting at any such meeting. Proof of
execution of any such instrument or of a writing appointing any such agent, or
the holding by any Person of a Debt Security, shall be sufficient for any
purpose of this Indenture and (subject to Section 601) conclusive in favor of
the Trustee and the Company, if made in the manner provided in this Section. The
record of any meeting of Holders of Debt Securities shall be proved in the
manner provided in Section 1406.

                                       11
<PAGE>

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

                  (c) The ownership of Registered 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 in the amount and with the
serial numbers 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.

                  (e) The fact and date of execution of any such instrument or
writing, the authority of the Person executing the same and the principal amount
and serial numbers of Bearer Securities held by the Person so executing such
instrument or writing and the date of holding the same may also be proved in any
other manner which the Trustee deems sufficient; and the Trustee may in any
instance require further proof with respect to any of the matters referred to in
this Section.

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

                  (g) For purposes of determining the principal amount of
Outstanding Debt Securities of any series the Holders of which are required,
requested or permitted to give any request, demand, authorization, direction,
notice, consent, waiver or take any other Act under this Indenture, (i) each
Original Issue Discount Security shall be deemed to have the principal amount
determined by the Trustee that could be declared to be due and payable pursuant
to the terms of such Original Issue Discount Security as of the date there is
delivered to the Trustee and, where it is hereby expressly required, to the
Company, such Act by Holders of the required aggregate principal amount of the
Outstanding Debt Securities of such series and (ii) each Debt Security
denominated in a Foreign Currency or composite currency shall be deemed to have
the principal amount determined by the Exchange Rate Agent by converting the
principal amount of such Debt Security in the currency in which such Debt
Security is denominated into Dollars at the Exchange Rate as of the date such
Act is delivered to the Trustee and, where it is hereby expressly required, to
the Company, by Holders of the required aggregate principal amount of the
Outstanding Debt Securities of such series.

                  (h) The Company may set any day as a record date for the
purpose of determining the Holders of Outstanding Debt Securities of any series
entitled to give, make or take any request, demand, authorization, direction,
notice, consent, waiver or other action provided or permitted by this Indenture
to be given, made or taken by Holders of Debt Securities of such series,
PROVIDED that the Company may not set a record date for, and the provisions of
this paragraph shall not apply with respect to, the giving or making of any
notice, declaration, request or direction referred to in the next paragraph. If
any record date is set pursuant to this paragraph, the Holders of Outstanding
Debt Securities of the relevant series on such record date, and no other
Holders, shall be entitled to take the relevant action, whether or not such
Holders remain Holders after such record date; PROVIDED that no such action
shall be effective hereunder unless taken on or prior to the applicable
Expiration Date (as defined below) by Holders of the requisite principal amount
of Outstanding Debt Securities of such series on such record date. Nothing in
this paragraph shall be construed to prevent the Company from setting a new
record date for any action for which a record date has previously been set
pursuant to this paragraph (whereupon the record date previously set shall
automatically and with no action by any Person be cancelled and of no effect),
and nothing in this paragraph shall be construed to render ineffective any
action taken by Holders of the requisite principal amount of Outstanding Debt
Securities of the relevant series on the date such action is taken. Promptly
after any record date is set pursuant to this paragraph, the Company, at its own
expense, shall cause notice of such record date, the proposed action by Holders
and the applicable Expiration Date to be given to the Trustee in writing and to
each Holder of Debt Securities of the relevant series in the manner set forth in
Section 106.

                  The Trustee may set any day as a record date for the purpose
of determining the Holders of Outstanding Debt Securities of any series entitled
to join in the giving or making of (i) any notice of an Event of Default, (ii)
any declaration of acceleration referred to in Section 502, (iii) any request to
institute proceedings referred to in Section 507(2), or (iv) any direction
referred to in Section 512, in each case with respect to Debt Securities of such
series. If any record date is set pursuant to this paragraph, the Holders of
Outstanding Debt Securities of such series on such record date, and no other
Holders, shall be entitled to join in such notice, declaration, request or
direction, whether or not such Holders remain Holders after such record date;
PROVIDED that no such action shall be effective hereunder unless taken on or
prior to the applicable Expiration Date by Holders of the requisite principal
amount of Outstanding Debt Securities of such series on such record date.
Nothing in this paragraph shall be construed to prevent the Trustee from setting
a new record date for any action for which a record date has previously been set
pursuant to this paragraph (whereupon the record date previously set shall
automatically and with no action by any Person be cancelled and of no effect),
and nothing in this paragraph shall be construed to render ineffective any
action taken by Holders of the requisite principal amount of Outstanding Debt
Securities of the relevant series on the date such action is taken. Promptly
after any record date is set pursuant to this paragraph, the Trustee, at the
Company's expense, shall cause notice of such record date, the proposed action
by Holders and the applicable Expiration Date to be given to the Company in
writing and to each Holder of Debt Securities of the relevant series in the
manner set forth in Section 106.

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

                                       13
<PAGE>

Section 106, on or prior to the existing Expiration Date. If an Expiration Date
is not designated with respect to any record date set pursuant to this Section,
the party hereto which set such record date shall be deemed to have initially
designated the 180th day after such record date as the Expiration Date with
respect thereto, subject to its right to change the Expiration Date as provided
in this paragraph.

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

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

                  (1) the Trustee by any Holder or by the Company shall be
         sufficient for every purpose hereunder (unless otherwise herein
         expressly provided), if in writing and sent by certified mail or by
         courier to the Trustee at its Corporate Trust Office, or

                  (2) the Company by the Trustee or by any Holder shall be
         sufficient for every purpose hereunder (unless otherwise herein
         expressly provided) if in writing and sent by certified mail or by
         courier to the Company addressed to the attention of its Secretary at
         the address of its principal office specified in the first paragraph of
         this instrument or at any other address previously furnished in writing
         to the Trustee by the Company.

                  SECTION 106. NOTICE TO HOLDERS; WAIVER.

                  Except as otherwise expressly provided herein, where this
Indenture provides for notice to Holders of any event, (1) such notice shall be
sufficiently given to Holders of Registered Securities if in writing and mailed,
first-class postage prepaid, to each Holder of a Registered Security affected by
such event, at such Holder's address as it appears in the Security Register, not
later than the latest date, and not earlier than the earliest date, prescribed
for the giving of such notice; and (2) such notice shall be sufficiently given
to Holders of Bearer Securities by publication thereof in an Authorized
Newspaper in The City of New York and, if the Debt Securities of such series are
then listed on The International Stock Exchange of the United Kingdom and the
Republic of Ireland and such stock exchange shall so require, in London, and, if
the Debt Securities of such series are then listed on the Luxembourg Stock
Exchange and such stock exchange shall so require, in Luxembourg and, if the
Debt Securities of such series are then listed on any other stock exchange
outside the United States and such stock exchange shall so require, in any other
required city outside the United States or, if not practicable, in Europe on a
Business Day at least twice, the first such publication to be not later than the
latest date and not earlier than the earliest date prescribed for the giving of
such notice.

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

                                       14
<PAGE>

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

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

                  Where this Indenture provides for notice in any manner, such
notice may be waived in writing by the Person entitled to receive such notice,
either before or after the event, and such waiver shall be the equivalent of
such notice. Waivers of notice by Holders 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.

                  Any request, demand, authorization, direction, notice,
consent, election, waiver or other Act 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.

                  SECTION 107. CONFLICT WITH TRUST INDENTURE ACT.

                  If any provision hereof limits, qualifies or conflicts with
another provision hereof which is required to be included in this Indenture by
any of the provisions of the Trust Indenture Act, such required provision shall
control.

                  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.

                  SECTION 110. SEPARABILITY CLAUSE.

                  In case any provision in this Indenture or in the Debt
Securities or any coupons 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 Debt Securities or any
coupons, express or implied, shall give to any Person, other than the parties
hereto and their successors hereunder, any Paying Agent and the Holders, any
benefit or any legal or equitable right, remedy or claim under this Indenture.

                  SECTION 112. GOVERNING LAW.

                  This Indenture and the Debt Securities and any coupons shall
be governed by and construed in accordance with the laws of the State of New
York.

                  SECTION 113. LEGAL HOLIDAYS.

                  In any case where any Interest Payment Date, Redemption Date,
Repayment Date or Stated Maturity of any Debt Security shall not be a Business
Day at any Place of Payment, then (notwithstanding any other provision of this
Indenture or of the Debt Securities or any coupons) payment of interest or
principal (and premium, 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,
Redemption Date, Repayment Date or at the Stated Maturity, and no interest shall
accrue on the amount so payable for the period from and after such Interest
Payment Date, Redemption Date, Repayment Date or Stated Maturity, as the case
may be.

                  SECTION 114. EXEMPTION FROM INDIVIDUAL LIABILITY.

                  No recourse under or upon any obligation, covenant or
agreement of this Indenture, or of any Debt Security or any coupon, or for any
claim based thereon or otherwise in respect thereof, shall be had against any
incorporator, stockholder, officer or director, as such, past, present or
future, of the Company or of any successor corporation, either directly or
through the Company, whether by virtue of any constitution, statute or rule of

                  SECTION 203. DEBT SECURITIES IN GLOBAL FORM.

                  If Debt Securities of a series are issuable in whole or in
part in global form, as specified as contemplated by Section 301, then,
notwithstanding clause (10) of Section 301 and the provisions of Section 302,
such Global Security shall represent such of the outstanding Debt Securities of
such series as shall be specified therein and may provide that it shall
represent the aggregate amount of Outstanding Debt Securities from time to time
endorsed thereon and that the aggregate amount of Outstanding Debt Securities
represented thereby may from time to time be reduced to reflect exchanges. Any
endorsement of a Global Security to reflect the amount, or any increase or
decrease in the amount, of Outstanding Debt Securities represented thereby shall
be made 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 304.

                  The provisions of the last sentence of Section 303(g) shall
apply to any Debt Securities represented by a Debt Security in global form if
such Debt Security was never issued and sold by the Company and the Company
delivers to the Trustee the Debt 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 respect to the reduction in the principal amount
of Debt Securities represented thereby, together with the written statement
contemplated by the last sentence of Section 303(g).

                  Global Securities may be issued in either registered or bearer
form and in permanent form or, in the case of Bearer Securities, either
temporary or permanent form.

                  Debt Securities of each series shall be issuable in such form
and denominations as shall be specified in the form of Debt Security for such
series approved or established pursuant to Section 201 or in the Officers'

Securities of such series, if any, shall be issuable in denominations of $1,000
and any integral multiple thereof and the Bearer Securities of such series, if
any, shall be issuable in the denominations of $5,000.

                  SECTION 303. EXECUTION, AUTHENTICATION, DELIVERY AND DATING.

Company by its Chairman of the Board, a Vice Chairman of the Board, the
President or a Vice President, and by its Treasurer or one of its Assistant
Treasurers or its Secretary or one of its Assistant Secretaries under its
corporate seal reproduced thereon. The signature of any of these officers on the
Debt Securities may be

                                       21

manual or facsimile. Coupons shall bear the facsimile signature of an authorized
officer of the Company.

                  Debt Securities and 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 Debt Securities or coupons of any series or did not hold such offices at
the date of such Debt Securities or coupons.

                  (b) At any time and from time to time after the execution and
delivery of this Indenture, Debt Securities of any series may be executed by the
Company and delivered to the Trustee for authentication, and, except as
otherwise provided in this Article Three, shall thereupon be authenticated and
delivered by the Trustee upon Company Order, without any further action by the
Company; PROVIDED, HOWEVER, that, in connection with its original issuance, a
Bearer Security may be delivered only outside the United States and, except in
the case of a temporary Global Security, only if the Company or its agent shall
have received the certification required pursuant to Sections 304(b)(iii) and
(iv), unless such certification shall have been provided earlier pursuant to
section 304(b)(v) hereof, and only if the Company has no reason to know that
such certification is false.

                  To the extent authorized in or pursuant to a Board Resolution
and set forth in an Officers' Certificate, or established in one or more
indentures supplemental hereto, such written Company Order may be given by any
one officer or employee of the Company, may be electronically transmitted, and
may provide instructions as to registration of holders, principal amounts, rates
of interest, maturity dates and other matters contemplated by such Board
Resolution and Officers' Certificate or supplemental indenture to be so
instructed in respect thereof. Before authorizing and delivering the first Debt
Securities of any series (and upon request of the Trustee thereafter), the
Company shall deliver to the Trustee (i) the certificates called for under
Sections 201 and 301 hereof and (ii) an Opinion of Counsel described in the next
sentence.

                  In authenticating such Debt Securities, and accepting the
additional responsibilities under this Indenture in relation to any such Debt
Securities, the Trustee shall be entitled to receive, prior to the initial
authentication of such Debt Securities, and (subject to Section 601) shall be
fully protected in relying upon:

                  (i) a Board Resolution relating thereto and, if applicable, an
         appropriate record of any action taken pursuant to such resolution
         certified by the Secretary or an Assistant Secretary of the Company;

                  (ii) an executed supplemental indenture, if any, relating
         thereto;

                  (iii) an Officers' Certificate setting forth the form and
         terms of the Debt Securities of such series and coupons, if any,
         pursuant to Sections 201 and 301 and stating that all conditions
         precedent provided for in this Indenture relating to the issuance of
         such Debt Securities have been complied with; and

                                       22
<PAGE>

                  (iv) an Opinion of Counsel stating

                           (A) that the form of such Debt Securities and
                  coupons, if any, has been established in or pursuant to a
                  Board Resolution or by a supplemental indenture as permitted
                  by Section 201 in conformity with the provisions of this
                  Indenture;

                           (B) that the terms of such Debt Securities and
                  coupons, if any, have been established in or pursuant to a
                  Board Resolution or by a supplemental indenture as permitted
                  by Section 301 in conformity with the provisions of this
                  Indenture; and

                           (C) that such Debt Securities and coupons, if any,
                  when authenticated and delivered by the Trustee and issued by
                  the Company in the manner and subject to any conditions
                  specified in such Opinion of Counsel, will constitute valid
                  and binding obligations of the Company, enforceable in
                  accordance with their terms, subject, as to enforcement of
                  remedies, to applicable bankruptcy, reorganization,
                  insolvency, moratorium or other laws affecting creditors'
                  rights generally and the application of general principles of
                  equity and except further as enforcement thereof may be
                  limited by (i) requirements that a claim with respect to any
                  Debt Securities denominated other than in Dollars (or a
                  Foreign Currency or currency unit judgment in respect of such
                  claim) be converted into Dollars at a rate of exchange
                  prevailing on a date determined pursuant to applicable law or
                  (ii) governmental authority to limit, delay or prohibit the
                  making of payments in Foreign Currencies or currency units or
                  payments outside the United States.

                  (c) If the Company shall establish pursuant to Section 301
that the Debt Securities of a series are to be issued in whole or in part in the
form of one or more Global Securities, then the Company shall execute and the
Trustee shall, in accordance with this Section and the Company Order with
respect to such series, authenticate and deliver one or more Global Securities
in permanent or temporary form that (i) shall represent and shall be denominated
in an aggregate amount equal to the aggregate principal amount of the
Outstanding Debt Securities of such series to be represented by one or more
Global Securities, (ii) shall be registered in the name of the Depositary for
such Global Security or Securities or the nominee of such Depositary and (iii)
shall be delivered by the Trustee to such Depositary or pursuant to such
Depositary's instructions.

                  (d) The Trustee shall have the right to decline to
authenticate and deliver any Debt Securities under this Section 303 if the
issuance of such Debt Securities will adversely affect the Trustee's own rights,
duties or immunities under the Debt Securities and this Indenture or otherwise
in a manner which is not reasonably acceptable to the Trustee.

                  (e) If all the Debt Securities of any series are not to be
issued at one time, it shall not be necessary to deliver an Opinion of Counsel
at the time of issuance of each Debt Security, but such Opinion of Counsel, with
appropriate modifications, may instead be delivered at or prior to the time of
the first issuance of Debt Securities of such series.

                  (f) Each Registered Security shall be dated the date of its
authentication. Each Bearer Security shall be dated as of the date specified as
contemplated by Section 301.

                  (g) No Debt Security or coupon attached thereto shall be
entitled to any benefit under this Indenture or be valid or obligatory for any
purpose, unless there appears on such Debt Security a certificate of
authentication substantially in the form provided for herein executed by the
Trustee, and such certificate upon any Debt Security shall be conclusive
evidence, and the only evidence, that such Debt Security has been duly
authenticated and delivered hereunder. Except as permitted by Section 306, the
Trustee shall not authenticate and deliver any Bearer Security unless all
appurtenant coupons for interest then matured have been detached and cancelled.
Notwithstanding the foregoing, if any Debt Security or portion thereof shall
have been duly authenticated and delivered hereunder but never issued and sold
by the Company, and the Company shall deliver such Debt Security to the Trustee
for cancellation as provided in Section 309 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 Debt Security or portion thereof has never
been issued and sold by the Company, for all purposes of this Indenture such
Debt Security shall be deemed never to have been authenticated and delivered
hereunder and shall never be entitled to the benefits of this Indenture.

                  (h) Each Depositary designated pursuant to Section 301 for a
Global Security in registered form must, at the time of its designation and at
all times while it serves as Depositary, be a clearing agency registered under
the Securities Exchange Act of 1934 and any other applicable statute or
regulation.

                  SECTION 304. TEMPORARY DEBT SECURITIES.

                  (a) Pending the preparation of definitive Debt Securities of
any series, the Company may execute, and upon receipt of documents required by
Sections 301 and 303, together with a Company Order, the Trustee shall
authenticate and deliver, temporary Debt Securities which are printed,
lithographed, typewritten, mimeographed or otherwise produced, in any
denomination, substantially of the tenor and terms of the definitive Debt
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 Debt Securities may determine, as evidenced by their
signatures on such Debt Securities. In the case of Debt Securities of any series
issuable as Bearer Securities, such temporary Debt Securities may be in global
form, representing all or any part of the Outstanding Debt Securities of such
series.

                  (b) Unless otherwise provided pursuant to Section 301:

                  (i) Except in the case of temporary Debt Securities in global
         form, if temporary Debt Securities of any series are issued, the
         Company will cause definitive Debt Securities of such series to be
         prepared without unreasonable delay. After the preparation of
         definitive Debt Securities of such series, the related temporary Debt
         Securities shall be exchangeable for such definitive Debt Securities
         upon surrender of the temporary Debt Securities of such series at the
         office or agency of the Company in the Place of Payment for such
         series, without charge to the Holder. Upon surrender for cancellation
         of any one or more temporary Debt Securities of any series
         (accompanied, if applicable, by all unmatured coupons and all matured
         coupons in default appertaining thereto), the Company shall execute and
         the Trustee shall authenticate and deliver in exchange therefor a like
         principal amount of definitive Debt Securities of the same series of
         like tenor and terms and of authorized denominations; PROVIDED,
         HOWEVER, that no Bearer Security shall be delivered in exchange for a
         Registered Security; and PROVIDED, FURTHER,

                                       24
<PAGE>

that a Bearer Security shall be delivered in exchange for a Bearer Security only
in compliance with the conditions set forth in Section 305.

                  (ii) If Debt Securities of any series are issued in temporary
         global form, any such temporary Global Security shall, unless otherwise
         provided pursuant to Section 301, be delivered to the Depositary for
         the benefit of Euroclear and Clearstream, for credit to the respective
         accounts of the beneficial owners of such Debt Securities (or to such
         other accounts as they may direct).

                  (iii) 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 (the "Global Exchange Date"), the
         Company shall deliver definitive Debt Securities to the Trustee or the
         agent appointed by the Company pursuant to Section 301 to effect the
         exchange of the temporary Global Security for definitive Debt
         Securities (the "Global Exchange Agent"), in an aggregate principal
         amount equal to the principal amount of such temporary Global Security,
         executed by the Company. On or after the Global Exchange Date, such
         temporary Global Security shall be surrendered by the Depositary to the
         Global Exchange Agent, to be exchanged, in whole or from time to time
         in part, for definitive Debt Securities without charge and the Trustee
         or the Global Exchange Agent, if authorized by the Trustee pursuant to
         Section 614, shall authenticate and deliver, in exchange for each
         portion of such temporary Global Security, an equal aggregate principal
         amount of definitive Debt Securities of the same series of authorized
         denominations and of like tenor and terms as the portion of such
         temporary Global Security to be exchanged. Upon any exchange of a part
         of such temporary Global Security for definitive Debt Securities, the
         portion of the principal amount and any interest thereon so exchanged
         shall be endorsed by the Global Exchange Agent on a schedule to such
         temporary Global Security, whereupon the principal amount and interest
         payable with respect to such temporary Global Security shall be reduced
         for all purposes by the amount so exchanged and endorsed. The
         definitive Debt Securities to be delivered in exchange for any such
         temporary Global Security shall be in bearer form, registered form,
         global registered form or global bearer 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, in the case of the exchange of
         the temporary Global Security for definitive Bearer Securities
         (including a definitive Global Bearer Security), upon such presentation
         by the Depositary, such temporary Global Security shall be accompanied
         by a certificate signed by Euroclear as to the portion of such
         temporary Global Security held for its account then to be exchanged and
         a certificate signed by Clearstream 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 B to this Indenture; and PROVIDED, FURTHER,
         that definitive Bearer Securities (including a definitive Global Bearer
         Security) shall be delivered in exchange for a portion of a temporary
         Global Security only in compliance with the requirements of Section
         303.

                  (iv) The interest of a beneficial owner of Debt Securities of
         a series in a temporary Global Security shall be exchanged for
         definitive Debt Securities of the same series and of like tenor and
         terms following the Global Exchange Date when the account holder
         instructs Euroclear or Clearstream, as the case may be, to request such
         exchange on such account holder's behalf and, in the case of the
         exchange of the temporary Global Security for definitive Bearer
         Securities (including a definitive Global Bearer Security), the account
         holder delivers to

                                       25
<PAGE>

         Euroclear or Clearstream, as the case may be, a certificate in the form
         set forth in Exhibit A-1 and, if applicable, A-2 to this Indenture,
         dated no earlier than 15 days prior to the Global Exchange Date, copies
         of which certificate shall be available from the offices of Euroclear
         and Clearstream, the Global Exchange Agent, any authenticating agent
         appointed for such series of Debt 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
         Debt 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 Debt Securities in person at the offices of
         Euroclear and Clearstream. Definitive Debt 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.

                  (v) Until exchanged in full as hereinabove provided, the
         temporary Debt Securities of any series shall in all respects be
         entitled to the same benefits under this Indenture as definitive Debt
         Securities of the same series and of like tenor and terms authenticated
         and delivered hereunder, except that interest payable on a temporary
         Global Security on an Interest Payment Date shall be payable to
         Euroclear and Clearstream on such Interest Payment Date only if there
         has been delivered by Euroclear and Clearstream to the Global Exchange
         Agent a certificate or certificates in the form set forth in Exhibit B
         to this Indenture dated no earlier than the first Interest Payment
         Date, for credit without further interest 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 Clearstream,
         as the case may be, a certificate in the form set forth in Exhibit A-1
         and, if applicable, A-2 to this Indenture dated no earlier than the
         first Interest Payment Date. Any interest so received by Euroclear and
         Clearstream and not paid as herein provided prior to the Global
         Exchange Date shall be returned to the Global Exchange Agent which,
         upon expiration of two years after such Interest Payment Date, shall
         repay such interest to the Company in accordance with Section 1003.

                  SECTION 305. REGISTRATION; REGISTRATION OF TRANSFER AND
         EXCHANGE.

                  The Company shall cause to be kept at one of the offices or
agencies to be maintained by the Company in accordance with the provisions of
this Section 305 and Section 1002, with respect to the Debt Securities of each
series which are Registered Securities, a register (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. Pursuant to Section 301,
the Company shall appoint, with respect to Debt Securities of each series which
are Registered Securities, a "Security Registrar" for the purpose of registering
such Debt Securities and transfers and exchanges of such Debt Securities as
herein provided.

                  Upon surrender for registration of transfer of any Registered
Security of any series at the office or agency of the Company maintained for
such purpose, the Company shall execute, and the Trustee shall authenticate and
deliver, in the name of the designated transferee or transferees, one or more
new Registered Securities of the same series of any authorized denomination or
denominations, of like tenor and terms and aggregate principal amount.

                                       26
<PAGE>

                  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 form and denomination, of like tenor and terms and aggregate
principal amount, upon surrender of the Registered Securities to be exchanged at
such office or agency. Bearer Securities may not be delivered in exchange for
Registered Securities.

                  At the option of the Holder, Registered Securities or Bearer
Securities of any series may be issued in exchange for Bearer Securities (except
as otherwise specified as contemplated by Section 301 with respect to a Bearer
Security in global form) of the same series, of any authorized denominations and
of like tenor and terms and aggregate principal amount, 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, such exchange may be
effected if the Bearer Securities are accompanied by payment in funds acceptable
to the Company and the Trustee in an amount equal to the face amount of such
missing coupon or coupons, or the surrender of such missing coupon or coupons
may be waived by the Company and the Trustee if there 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 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 exchange for a Registered
Security of the same series and like tenor and terms 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 date for payment of Defaulted Interest, such Bearer
Security shall be surrendered without the coupon relating to such Interest
Payment Date or proposed date of payment, as the case may be.

                  Whenever any Debt Securities are so surrendered for exchange,
the Company shall execute, and the Trustee shall authenticate and deliver, the
Debt Securities which the Holder making the exchange is entitled to receive.

                  If at any time the Depositary for the Debt Securities of a
series notifies the Company that it is unwilling or unable to continue as
Depositary for the Debt Securities of such series or if at any time the
Depositary for the Debt Securities of such series shall no longer be eligible
under Section 303(h), the Company shall appoint a successor Depositary with
respect to the Debt Securities of such series. If a successor Depositary for the
Debt Securities of such series is not appointed by the Company within 90 days
after the Company receives such notice or becomes aware of such ineligibility,
the Company's election pursuant to Section 301(9) shall no longer be effective
with respect to the Debt Securities of such series and the Company will execute,
and the Trustee, upon receipt of a Company Order for the authentication and
delivery of definitive Debt Securities of such series, will authenticate and
deliver, Debt Securities of such series in definitive form in an aggregate
principal amount equal to the principal amount of the Global Security or
Securities representing such series in exchange for such Global Security or
Securities.

                                       27
<PAGE>

                  The Company may at any time and in its sole discretion
determine that the Debt Securities of any series issued in the form of one or
more Global Securities shall no longer be represented by such Global Security or
Securities. In such event the Company will execute, and the Trustee, upon
receipt of a Company Order for the authentication and delivery of definitive
Debt Securities of such series, will authenticate and deliver, Debt Securities
of such series in definitive form and in an aggregate principal amount equal to
the principal amount of the Global Security or Securities representing such
series in exchange for such Global Security or Securities.

                  If specified by the Company pursuant to Section 301 with
respect to a series of Debt Securities, the Depositary for such series of Debt
Securities may surrender a Global Security for such series of Debt Securities in
exchange in whole or in part for Debt Securities of such series of like tenor
and terms and in definitive form on such terms as are acceptable to the Company
and such Depositary. Thereupon, the Company shall execute, and the Trustee shall
authenticate and deliver, without charge to any Holder,

                  (a) to each Person specified by such Depositary a new Debt
         Security or Securities of the same series, of like tenor and terms and
         of any authorized denominations as requested by such person in
         aggregate principal amount equal to and in exchange for such Person's
         beneficial interest in the Global Security; and

                  (b) to such Depositary a new Global Security of like tenor and
         terms and in a denomination equal to the difference, if any, between
         the principal amount of the surrendered Global Security and the
         aggregate principal amount of Debt Securities delivered to Holders
         thereof.

                  In any exchange provided for in any of the preceding three
paragraphs, the Company will execute and the Trustee will authenticate and
deliver Debt Securities (a) in definitive registered form in authorized
denominations, if the Debt Securities of such series are issuable as Registered
Securities, (b) in definitive bearer form in authorized denominations, with
coupons attached, if the Debt Securities of such series are issuable as Bearer
Securities or (c) as either Registered or Bearer Securities, as shall be
specified by the beneficial owner thereof, if the Debt Securities of such series
are issuable in either form; PROVIDED, HOWEVER, that no definitive Bearer
Security shall be delivered in exchange for a temporary Global Security unless
the Company or its agent shall have received from the person entitled to receive
the definitive Bearer Security a certificate substantially in the form set forth
in Exhibit A-1 and, if applicable, A-2 hereto; and PROVIDED FURTHER that
delivery of a Bearer Security shall occur only outside the United States; and
PROVIDED FURTHER that no definitive Bearer Security will be issued if the
Company has reason to know that any such certificate is false.

                  Upon the exchange of a Global Security for Debt Securities in
definitive form, such Global Security shall be cancelled by the Trustee.
Registered Securities issued in exchange for a Global Security pursuant to this
Section shall be registered in such names and in such authorized denominations
as the Depositary for such Global Security, pursuant to instructions from its
direct or indirect participants or otherwise, shall instruct the Trustee. The
Trustee shall deliver such Registered Securities to the persons in whose names
such Debt Securities are so registered. The Trustee shall deliver Bearer
Securities issued in exchange for a Global Security pursuant to this Section to
the persons, and in such authorized denominations, as the Depositary for such
Global Security, pursuant to instructions from its direct or indirect
participants or otherwise, shall instruct the Trustee; PROVIDED,

                                       28
<PAGE>

HOWEVER, that no definitive Bearer Security shall be delivered in exchange for a
temporary Global Security unless the Company or its agent shall have received
from the person entitled to receive the definitive Bearer Security a certificate
substantially in the form set forth in Exhibit A-1 and, if applicable, A-2
hereto; and PROVIDED FURTHER that delivery of a Bearer Security shall occur only
outside the United States; and PROVIDED FURTHER that no definitive Bearer
Security will be issued if the Company has reason to know that any such
certificate is false.

                  All Debt Securities issued upon any registration of transfer
or exchange of Debt Securities shall be the valid obligations of the Company,
evidencing the same debt, and entitled to the same benefits under this
Indenture, as the Debt 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,
the Security Registrar or the Trustee) be duly endorsed, or be accompanied by a
written instrument of transfer in form satisfactory to the Company, the Security
Registrar and the Trustee duly executed, by the Holder thereof or such Holder's
attorney duly authorized in writing.

                  No charge to any Holder shall be made for any registration of
transfer or exchange of Debt Securities, but the Company may require payment of
a sum sufficient to cover any tax or other governmental charge that may be
imposed in connection with any transfer, registration of transfer or exchange of
Debt Securities, other than exchanges expressly provided in this Indenture to be
made at the Company's own expense or without expense or without charge to the
Holders.

                  The Company shall not be required (i) to issue, register the
transfer of or exchange Debt Securities of any particular series to be redeemed
for a period of fifteen days preceding the first publication of the relevant
notice of redemption or, if Registered Securities are outstanding and there is
no publication, the mailing of the relevant notice of redemption of Debt
Securities of such series selected for redemption under Section 1103 and ending
at the close of business on the day of such mailing, or (ii) to register the
transfer of or exchange any Registered Security so selected for redemption in
whole or in part, except the unredeemed portion of such Registered 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 like tenor and terms of that series, PROVIDED that such Registered
Security shall be simultaneously surrendered for redemption.

                  Notwithstanding anything herein to the contrary, the exchange
of Bearer Securities into Registered Securities shall be subject to applicable
laws and regulations in effect at the time of exchange; neither the Company, the
Trustee nor the Security Registrar shall exchange any Bearer Securities into
Registered Securities if it has received an Opinion of Counsel that as a result
of such exchanges the Company would suffer adverse consequences under the United
States Federal income tax laws and regulations then in effect and the Company
has delivered to the Trustee a Company Order directing the Trustee not to make
such exchanges thereafter unless and until the Trustee receives a subsequent
Company Order to the contrary. The Company shall deliver copies of such Company
Orders to the Security Registrar.

                  SECTION 306. MUTILATED, DESTROYED, LOST AND STOLEN DEBT
         SECURITIES.

                  If (i) any mutilated Debt Security or a Bearer Security with a
mutilated coupon appertaining to it is surrendered to a Paying Agent outside the
United States designated by the Company, or, in the case of any Registered
Security, to the Trustee, or (ii) the Company and the Trustee receive evidence
to their satisfaction of the destruction, loss or theft of any Debt Security or
coupon, and there is delivered to the Company and the Trustee such security or
indemnity as may be required by them to save each of them harmless, then, in the
absence of notice to the Company and the Trustee that such Debt Security or
coupon has been acquired by a bona fide purchaser, the Company shall execute and
upon its written request the Trustee shall authenticate and deliver, in exchange
for any such mutilated Debt Security or Bearer Security with a mutilated coupon
appertaining to it or to which a destroyed, lost or stolen coupon appertains
(with all appurtenant coupons not destroyed, lost or stolen) or in lieu of any
such destroyed, lost or stolen Debt Security, a new Debt Security of like tenor
and terms and principal amount, bearing a number not contemporaneously
outstanding, with coupons corresponding to the coupons, if any, appertaining to
such destroyed, lost or stolen Debt Security or to the Debt Security to which
such destroyed, lost or stolen coupon appertains; PROVIDED, HOWEVER, that any
such new Bearer Security will be delivered only in compliance with the
conditions set forth in Section 305.

                  In case any such mutilated, destroyed, lost or stolen Debt
Security or coupon has become or is about to become due and payable, the Company
in its discretion may, instead of issuing a new Debt Security, pay such Debt
Security or coupon; PROVIDED, HOWEVER, that payment of principal of (and
premium, if any) and any interest 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 PROVIDED, FURTHER, that, with respect to
any such coupons, interest represented thereby (but not any additional amounts
payable as provided in Section 1006), shall be payable only upon presentation
and surrender of the coupons appertaining thereto.

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

                  Every new Debt Security of any series, with its coupons, if
any, issued pursuant to this Section in lieu of any destroyed, lost or stolen
Debt Security, or in exchange for a Bearer Security to which a destroyed, lost
or stolen coupon appertains, shall constitute an original additional contractual
obligation of the Company, whether or not the destroyed, lost or stolen Debt
Security and its coupons, if any, or the destroyed, lost or stolen coupon shall
be at any time enforceable by anyone, and any such new Debt Security and
coupons, if any, shall be entitled to all the benefits of this Indenture equally
and proportionately with any and all other Debt Securities of that series and
their coupons, if any, duly issued hereunder.

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

                  SECTION 307. PAYMENT OF INTEREST; INTEREST RIGHTS PRESERVED.

                  Interest 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 that Registered Security (or one or more Predecessor
Securities) is registered at the close of business on the Regular Record Date
for such interest. In case a Bearer Security of any series is surrendered in
exchange for a Registered Security of such series after the close of business
(at an office or agency in a Place of Payment for such series) on any Regular
Record Date and before the opening of business (at such office or agency) on the
next succeeding Interest Payment Date, such Bearer Security shall be surrendered
without the coupon relating to such Interest Payment Date and interest will not
be payable on such Interest Payment Date 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. At the option of the Company, payment of interest on any Registered
Security may be made by check in the currency designated for such payment
pursuant to the terms of such Registered Security mailed to the address of the
Person entitled thereto as such address shall appear in the Security Register or
by wire transfer to an account in such currency designated by such Person in
writing not later than ten days prior to the date of such payment.

                  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 (herein called "Defaulted Interest") shall forthwith cease to be
payable to the registered Holder on the relevant Regular Record Date by virtue
of his having been such Holder, and such Defaulted Interest may be paid by the
Company, at its election in each case, as provided in Clause (1) or (2) below:

                  (1) The Company may elect to make payment of any Defaulted
         Interest to the Persons in whose names the 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 and/or
         Government Obligations the payments of principal and interest on which
         when due (and without reinvestment) will provide money in such amounts
         as will (together with any money irrevocably deposited in trust with
         the Trustee, without investment) be equal to the aggregate amount
         proposed to be paid in respect of such Defaulted Interest or shall make
         arrangements satisfactory to the Trustee for such deposit prior to the
         date of the proposed payment, such money and/or Government Obligations
         when deposited to be held in trust for the benefit of the Persons
         entitled to such Defaulted Interest as in this Clause provided.
         Thereupon the Trustee shall fix a Special Record Date for the payment
         of such Defaulted Interest which shall be not more than 15 days and not
         less than 10 days prior to the date of the proposed payment and not
         less than 10 days after the receipt by the Trustee of the notice of the
         proposed payment. The Trustee shall promptly notify the Company of such
         Special Record Date. Unless the Trustee is acting as the Security
         Registrar, promptly after such Special Record Date, the Company shall
         furnish the Trustee with a list, or shall make arrangements
         satisfactory to the Trustee with respect thereto, of the names and
         addresses of, and principal amounts of Registered Securities of such
         series held by, the Holders appearing on the Security Register at the
         close of business on such Special Record Date. In the name and at the
         expense of the Company, the Trustee

                                       31
<PAGE>

         shall cause notice of the proposed payment of such Defaulted Interest
         and the Special Record Date therefor to be mailed, first-class postage
         prepaid, to each Holder of Registered Securities of such series at his
         address as it appears in the Security Register, 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 mailed as aforesaid, such Defaulted Interest shall be paid 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 such Special Record Date and shall no longer be payable
         pursuant to the following Clause (2). In case a Bearer Security of any
         series is surrendered at the office or agency in a Place of Payment for
         such series in exchange for a Registered Security of such series after
         the close of business at such office or agency on 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
         proposed date of payment and Defaulted Interest will not be payable on
         such proposed date of payment 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.

                  (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
         the Registered Securities may be listed, and upon such notice as may be
         required by such exchange, if, after notice given by the Company to the
         Trustee of the proposed payment pursuant to this Clause, such manner of
         payment shall be deemed practicable by the Trustee.

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

                  Subject to the limitations set forth in Section 1002, the
Holder of any coupon appertaining to a Bearer Security shall be entitled to
receive the interest payable on such coupon upon presentation and surrender of
such coupon on or after the Interest Payment Date of such coupon at an office or
agency maintained for such purpose pursuant to Section 1002.

                  SECTION 308. 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 of 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 Section 307)
interest on such Registered Security and for all other purposes whatsoever,
whether or not such Registered Security be overdue, and neither the Company, the
Trustee nor any agent of the Company or the Trustee shall be affected by notice
to the contrary.

                  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 Bearer Security or coupon for the purpose of
receiving payment thereof or on account thereof and for all other

                                       32
<PAGE>

purposes whatsoever, whether or not such Bearer Security or coupon be overdue,
and neither the Company, the Trustee nor any agent of the Company or the Trustee
shall be affected by notice to the contrary.

                  None of the Company, the Trustee, any Paying Agent or the
Security Registrar will have any responsibility or liability for any aspect of
the records relating to or payments made on account of beneficial ownership
interests of a Global Security or for maintaining, supervising or reviewing any
records relating to such beneficial ownership interests.

                  SECTION 309. CANCELLATION.

                  Unless otherwise provided with respect to a series of Debt
Securities, all Debt Securities and coupons surrendered for payment, redemption,
repayment, transfer, exchange or credit against any sinking fund payment
pursuant to this Indenture shall, if surrendered to the Company or any agent of
the Company, be delivered to the Trustee and shall be promptly cancelled by it.
The Company may at any time deliver to the Trustee for cancellation any Debt
Securities previously authenticated and delivered hereunder which the Company
may have acquired in any manner whatsoever, and all Debt Securities so delivered
shall be promptly cancelled by the Trustee. No Debt Securities shall be
authenticated in lieu of or in exchange for any Debt Securities cancelled as
provided in this Section, except as expressly permitted by this Indenture. All
cancelled Debt Securities and coupons held by the Trustee shall be destroyed and
certification of their destruction delivered to the Company unless by a Company
Order the Company shall direct that the cancelled Debt Securities or coupons be
returned to it.

                  SECTION 310. COMPUTATION OF INTEREST.

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

                  SECTION 311. CERTIFICATION BY A PERSON ENTITLED TO DELIVERY OF
         A BEARER SECURITY.

                  Whenever any provision of this Indenture or a Debt Security
contemplates that certification be given by a Person entitled to delivery of a
Bearer Security, such certification shall be provided substantially in the form
of Exhibit A-1 and, if applicable, A-2 hereto, with only such changes as shall
be approved by the Company and consented to by the Trustee, whose consent shall
not unreasonably be withheld.

                  SECTION 312. JUDGMENTS.

                  The Company agrees that, to the fullest extent possible under
applicable law and except as may otherwise be specified as contemplated in
Section 301, (a) the obligation, if any, of the Company to pay the principal of
(and premium, if any) and interest on the Debt Securities of any series and any
appurtenant coupons in a Foreign Currency, composite currency or Dollars (the
"Designated Currency") as may be specified pursuant to Section 301 is of the
essence, and judgments in respect of such Debt Securities shall be given in the
Designated Currency; (b) the obligation of the Company to make payments in the
Designated Currency of the principal of (and premium, if any) and interest on

                                       33
<PAGE>

such Debt Securities and any appurtenant coupons shall, notwithstanding any
payment in any other currency (whether pursuant to a judgment or otherwise), be
discharged only to the extent of the amount in the Designated Currency that the
Holder receiving such payment may, in accordance with normal banking procedures,
purchase with the sum paid in such other currency (after any premium and cost of
exchange) in the country of issue of the Designated Currency in the case of
Foreign Currency or Dollars or in the international banking community in the
case of a composite currency on the Business Day immediately following the day
on which such Holder receives such payment; (c) if the amount in the Designated
Currency that may be so purchased for any reason falls short of the amount
originally due, the Company shall pay such additional amounts as may be
necessary to compensate for such shortfall; and (d) any obligation of the
Company not discharged by such payment shall be due as a separate and
independent obligation and, until discharged as provided herein, shall continue
in full force and effect.

                                  ARTICLE FOUR

                           SATISFACTION AND DISCHARGE

                  SECTION 401. SATISFACTION AND DISCHARGE OF INDENTURE.

                  This Indenture shall upon Company Request cease to be of
further effect (except as to any surviving rights of registration of transfer or
exchange of Debt Securities herein expressly provided for and rights to receive
payments of principal and interest thereon and any right to receive additional
amounts, as provided in Section 1006) and the Trustee, at the expense of the
Company, shall execute proper instruments acknowledging satisfaction and
discharge of this Indenture when

                  (1) either

                           (A) all Debt Securities theretofore authenticated and
                  delivered and all coupons appertaining thereto (other than (i)
                  coupons appertaining to Bearer Securities surrendered in
                  exchange for Registered Securities and maturing after such
                  exchange, surrender of which is not required or has been
                  waived as provided in Section 305, (ii) Debt Securities and
                  coupons which have been destroyed, lost or stolen and which
                  have been replaced or paid as provided in Section 306, (iii)
                  coupons appertaining to Bearer Securities called for
                  redemption or surrendered for repayment and maturing after the
                  relevant Redemption Date or Repayment Date, as appropriate,
                  surrender of which has been waived as provided in Section 1106
                  or 1303 and (iv) Debt Securities and coupons for whose payment
                  money and/or Government Obligations have theretofore been
                  deposited in trust or segregated and held in trust by the
                  Company and thereafter repaid to the Company or discharged
                  from such trust, as provided in Section 1003) have been
                  delivered to the Trustee cancelled or for cancellation; or

                           (B) all such Debt Securities not theretofore

                           Stated Maturity within one year, or

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

                  and the Company, in the case of (B)(i), (B)(ii) or (B)(iii)
                  above, has irrevocably deposited or caused to be deposited
                  with the Trustee as trust funds in trust for the purpose money
                  and/or Government Obligations the payments of principal and
                  interest on which when due (and without reinvestment) will
                  provide money in such amounts as will (together with any money
                  irrevocably deposited in trust with the Trustee, without
                  investment) be sufficient to pay and discharge the entire
                  indebtedness on such Debt Securities and coupons of such
                  series for principal (and premium, if any) and interest, and
                  any mandatory sinking fund, repayment or analogous payments
                  thereon, on the scheduled due dates therefor to the date of
                  such deposit (in the case of Debt Securities and coupons which
                  have become due and payable) or to the Stated Maturity or
                  Redemption Date, if any, and all Repayment Dates (in the case
                  of Debt Securities repayable at the option of the Holders
                  thereof); PROVIDED, HOWEVER, that in the event a petition for
                  relief under any applicable Federal or state bankruptcy,
                  insolvency, reorganization or other similar law is filed with
                  respect to the Company within 91 days after the deposit, the
                  obligations of the Company under the Indenture with respect to
                  the Debt Securities of such series shall not be deemed
                  terminated or discharged, and in such event the Trustee shall
                  be required to return the deposited money and Government
                  Obligations then held by the Trustee to the Company;

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

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

Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Company to the Trustee under Section 607 and, if money or
Government Obligations shall have been deposited with the Trustee pursuant to
Subclause (B) of Clause (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 AND GOVERNMENT
         OBLIGATIONS.

                  (a) Subject to the provisions of the last paragraph of Section
1003, all money and Government Obligations deposited with the Trustee pursuant
to Section 401, 403 or 1501 shall be held in trust and such money and the
principal and interest received on such Government Obligations shall be applied
by it, in accordance with the provisions of the Debt Securities, any 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

                                       35
<PAGE>

(and premium, if any) and interest for whose payment such money or Government
Obligations have been deposited with the Trustee.

                  (b) The Trustee shall deliver or pay to the Company from time
to time upon Company Request any Government Obligations or money held by it as
provided in Section 403 or 1501 which, in the opinion of a nationally recognized
firm of independent public accountants expressed in a written certification
thereof delivered to the Trustee, are then in excess of the amount thereof which
then would have been required to be deposited for the purpose for which such
Government Obligations or money were deposited or received.

                  (c) The Trustee shall deliver to the Company from time to time
upon Company Request any Government Obligations held by it as provided in
Section 403 or 1501, provided that the Company in substitution therefor
simultaneously delivers to the Trustee, money or other Government Obligations
which, in the opinion of a nationally recognized firm of independent public
accountants expressed in a written certification thereof delivered to the
Trustee, would then be sufficient to satisfy the Company's payment obligations
in respect of the Debt Securities in the manner contemplated by Section 403 or
1501.

                  SECTION 403. SATISFACTION, DISCHARGE AND DEFEASANCE OF DEBT
         SECURITIES OF ANY SERIES.

                  If this Section 403 is specified, as contemplated by Section
301, to be applicable to Debt Securities of any series, then, notwithstanding
Section 401, (i) the Company shall be deemed to have paid and discharged the
entire indebtedness on all the Outstanding Debt Securities of any such series
and related coupons; (ii) the provisions of this Indenture as it relates to such
Outstanding Debt Securities and related coupons shall no longer be in effect
(except as to (A) the rights of Holders of Debt Securities to receive, from the
trust fund described in subparagraph (1) below, payment of (x) the principal of
(and premium, if any) and any installment of principal of (and premium, if any)
or interest on such Debt Securities and related coupons on the Stated Maturity
of such principal (and premium, if any) or installment of principal (and
premium, if any) or interest or (y) any mandatory sinking fund, repayment or
analogous payments applicable to the Debt Securities of that series on that day
on which such payments are due and payable in accordance with the terms of this
Indenture and of such Debt Securities, (B) the Company's obligations with
respect to such Debt Securities under Sections 304, 305, 306, 1002, 1003 and
1006, and (C) the rights, powers, trusts, duties and immunities of the Trustee
hereunder, including those under Section 607 hereof); and (iii) the Trustee, at
the expense of the Company, shall, upon Company Order, execute proper
instruments acknowledging satisfaction and discharge of such indebtedness, when

                  (1) either

                           (A) with respect to all Outstanding Debt Securities
                  of such series and related coupons, with reference to this
                  Section 403, the Company has deposited or caused to be
                  deposited with the Trustee irrevocably, as trust funds in
                  trust, money and/or Government Obligations the payments of
                  principal and interest on which when due (and without
                  reinvestment) will provide money in such amounts as will
                  (together with any money irrevocably deposited in trust with
                  the Trustee, without investment) be sufficient to pay and
                  discharge (i) the principal of (and premium, if any) and
                  interest on

                                       36
<PAGE>

                  the Outstanding Debt Securities of that series on the Stated
                  Maturity of such principal or interest or, if such series may
                  be redeemed by the Company prior to the Stated Maturity
                  thereof and the Company shall have given irrevocable
                  instructions to the Trustee to effect such redemption, at the
                  date fixed for such redemption pursuant to Article Eleven, and
                  (ii) any mandatory sinking fund payments or analogous payments
                  applicable to Debt Securities of such series on the date on
                  which such payments are due and payable in accordance with the
                  terms of this Indenture and of such Debt Securities; or

                           (B) the Company has properly fulfilled such other
                  means of satisfaction and discharge as is specified, as
                  contemplated by Section 301, to be applicable to the Debt
                  Securities of such series;

                  (2) the Company has paid or caused to be paid all sums payable
         with respect to the Outstanding Debt Securities of such series and
         related coupons;

                  (3) such deposit will not result in a breach of, or constitute
         a default under, this Indenture or any other agreement or instrument to
         which the Company is a party or by which it is bound;

                  (4) no Event of Default or event which, with the giving of
         notice or lapse of time, or both, would become an Event of Default
         pursuant to Section 501(1), (2), (3), (6) or (7) with respect to the
         Debt Securities of such series shall have occurred and be continuing on
         the date of such deposit and no Event of Default under Section 501(6)
         or Section 501(7) or event which, with the giving of notice or lapse of
         time, or both, would become an Event of Default under Section 501(6) or
         Section 501(7) shall have occurred and be continuing on the 91st day
         after such date; provided, however, that should that condition fail to
         be satisfied on or before such 91st day, the Trustee shall promptly,
         upon satisfactory receipt of evidence of such failure, return such
         deposit to the Company;

                  (5) if the Debt Securities of that series are then listed on
         any domestic or foreign securities exchange, the Company shall have
         delivered to the Trustee an Opinion of Counsel to the effect that such
         deposit, defeasance and discharge will not cause such Debt Securities
         to be delisted; and

                  (6) 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 the entire indebtedness of all Outstanding Debt Securities
         and related coupons have been complied with.

                  Any deposits with the Trustee referred to in Section 403(1)(A)
above shall be irrevocable and shall be made under the terms of an escrow or
trust agreement in form and substance satisfactory to the Trustee. If any
Outstanding Debt Securities of such series are to be redeemed prior to their
Stated Maturity, whether pursuant to any optional redemption provisions or in
accordance with any mandatory sinking fund requirement, the applicable escrow or
trust agreement shall provide therefor and the Company shall make such
arrangements as are satisfactory to the Trustee for the giving of notice of
redemption by the Trustee in the name, and at the expense, of the Company.

                  Upon the satisfaction of the conditions set forth in this
Section 403 with respect to all the Outstanding Debt Securities of any series,
the terms and conditions of such series, including the terms and conditions with
respect thereto set forth in this Indenture, shall no longer be binding upon, or
applicable to, the Company; provided that the Company shall not be discharged
from any payment obligations in respect of Debt Securities of such series which
are deemed not to be Outstanding under clause (iii) of the definition thereof if
such obligations continue to be valid obligations of the Company under
applicable law.

                  Notwithstanding the cessation, termination and discharge of
all obligations, covenants and agreements (except as provided above in this
Section 403) of the Company under this Indenture with respect to any series of
Debt Securities, the obligations of the Company to the Trustee under Section

         this Section specifically dealt with or which has expressly been
         included in this Indenture solely for the benefit of Debt Securities of
         a series other than such series), and continuance of such default or
         breach for a period of 90 days after there has been given by registered

                  (5) a default under any Indebtedness for money borrowed by the
         Company or any Subsidiary (including a default with respect to Debt
         Securities of any series other than that series) or under any Mortgage,
         indenture or instrument under which there may be issued or by which
         there may be secured or evidenced any Indebtedness for money borrowed
         by the Company or any Subsidiary (including this Indenture), whether
         such Indebtedness now exists or shall hereafter be created, which
         default shall have resulted in such Indebtedness in an outstanding
         principal amount in excess of $20 million becoming or being declared
         due and payable prior to the date on which it would otherwise have
         become due and payable, without such acceleration having been rescinded
         or annulled, or such Indebtedness having been discharged, within a
         period of 10 days after there shall have been given, by registered or
         certified mail, to the Company by the Trustee or to the Company and the
         Trustee by the Holders of at least 25% in principal amount of the
         Outstanding Securities of that series a written notice specifying such
         default and requiring the Company to cause such acceleration to be
         rescinded or annulled or cause such Indebtedness to be discharged and
         stating that such notice is a "Notice of Default" hereunder; or

                  (6) the entry by a court having jurisdiction in the premises
         of (A) a decree or order for relief in respect of the Company in an

         bankruptcy, insolvency, reorganization or other similar law or (B) a
         decree or order adjudging the Company a bankrupt or insolvent, or
         approving as properly filed a petition seeking reorganization,

         under any applicable Federal or State law, or appointing a custodian,
         receiver, liquidator, assignee, trustee, sequestrator or other similar
         official of the Company or of any substantial part of its property, or
         ordering the winding up or liquidation of its affairs, and the
         continuance of any such decree or order for relief or any such other
         decree or order unstayed and in effect for a period of 90 consecutive
         days; or

                  (7) the commencement by the Company of a voluntary case or
         proceeding under any applicable Federal or state bankruptcy,
         insolvency, reorganization or other similar law or of any other case or
         proceeding to be adjudicated a bankrupt or insolvent, or the consent by
         it to the entry of a decree or order for relief in respect of the
         Company in an involuntary case or proceeding under any applicable

         receiver, liquidator, assignee, trustee, sequestrator or similar
         official of the Company or of any substantial part of its property, or
         the making by it of an assignment for the benefit of creditors, or the
         admission by it in writing of its inability to pay its debts generally
         as they become due, or the taking of corporate action by the Company in
         furtherance of any such action; or

                  (8) any other Event of Default provided with respect to Debt
         Securities of such series specified as contemplated by Section 301.

                  SECTION 502. ACCELERATION OF MATURITY; RESCISSION AND
         ANNULMENT.

                  If an Event of Default with respect to Debt Securities of any
series at the time Outstanding occurs and is continuing, then and in every such
case the Trustee or the Holders of not less than 25% in principal amount of
Outstanding Debt Securities of such series may declare the principal amount (or,
if the Debt Securities of such series are Original Issue Discount Securities,
such portion of the principal amount as may be specified in the terms of such
series) of and all accrued but unpaid interest on all the Debt Securities of
such series to be due and payable immediately, by a notice in writing to the
Company (and to the Trustee if given by such Holders), and upon any such
declaration such principal amount (or specified amount) shall become immediately
due and payable. Upon payment of such amount, all obligations of the Company in
respect of the payment of principal of the Debt Securities of such series shall
terminate.

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

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

                           (A) all overdue installments of interest on all Debt
                  Securities of such series,

                           (B) the principal of (and premium, if any, on) any
                  Debt Securities of such series which have become due otherwise
                  than by such declaration of acceleration and interest thereon
                  at the rate or rates prescribed therefor in such Debt
                  Securities,

                           (C) to the extent that payment of such interest is
                  lawful, interest upon overdue installments of interest at the
                  rate or rates prescribed therefor in such Debt Securities, and

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

         and

                  (2) all Events of Default with respect to Debt Securities of
         such series, other than the non-payment of the principal of Debt
         Securities of such series which have become due solely by such
         declaration of acceleration, have been cured or waived as provided in
         Section 513.

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

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

                  The Company covenants that if:

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

                  (2) default is made in the payment of the principal of (or
         premium, if any, on) any Debt Security at the Maturity thereof,

the Company will, upon demand of the Trustee, pay to it, for the benefit of the
Holders of such Debt Securities and any related coupons, the amount then due and
payable on such Debt Securities and coupons for principal (and premium, if any)
and interest and, to the extent that payment of such interest shall be legally
enforceable, interest upon the overdue principal (and premium, if any) and, upon
overdue installments of interest, at the rate or rates prescribed therefor in
such Debt Securities, and, in addition thereto, such further amount as shall be
sufficient to cover the costs and expenses of collection, including the
reasonable compensation, expenses, disbursements and advances of the Trustee,
its agents and counsel.

                  If the Company fails to pay such amounts forthwith upon such
demand, the Trustee, in its own name and as trustee of an express trust, may
institute a judicial proceeding for the collection of the sums so due and
unpaid, and may prosecute such proceeding to judgment or final decree, and may
enforce the same against the Company or any other obligor upon such Debt
Securities and coupons 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 such Debt Securities and coupons, wherever situated.

                  If an Event of Default with respect to Debt Securities of any
series occurs and is continuing, the Trustee may in its discretion proceed to
protect and enforce its rights and the rights of the Holders of Debt Securities
of such series and any related coupons by such appropriate judicial proceedings
as the Trustee shall deem most effectual to protect and enforce any such rights,
whether for the specific enforcement of any covenant or agreement in this
Indenture or in aid of the exercise of any power granted herein, or to enforce
any other proper remedy.

                  SECTION 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 proceedings, or any voluntary or involuntary case under the
Federal bankruptcy laws as now or hereafter constituted, relative to the Company
or any other obligor upon the Debt Securities of a particular series or any
related coupons or the property of the Company or of such other obligor or their
creditors, the Trustee (irrespective of whether the principal of such Debt
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 or interest) shall be
entitled and empowered, by intervention in such proceedings or otherwise,

                                       41
<PAGE>

                  (1) 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 Debt Securities of such series and any appurtenant
         coupons 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

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

and any receiver, assignee, trustee, custodian, liquidator, sequestrator or
other similar official in any such 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 to
the Trustee any amount due it for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, and any other
amounts due the Trustee under Section 607.

                  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
Debt Securities or any coupons 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.

                  SECTION 505. TRUSTEE MAY ENFORCE CLAIMS WITHOUT POSSESSION OF
         DEBT SECURITIES OR COUPONS.

                  All rights of action and claims under this Indenture or the
Debt Securities or coupons may be prosecuted and enforced by the Trustee without
the possession of any of the Debt Securities or coupons or the production
thereof in any proceeding relating thereto, and any such proceeding instituted
by the Trustee shall be brought in its own name, as trustee of an express trust,
and any recovery 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 Debt
Securities and coupons 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
(and premium, if any) or interest, upon presentation of the Debt Securities or
any coupons, or both, as the case may be, and the notation thereon of the
payment if only partially paid and upon surrender thereof if fully paid:

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

                  SECOND: To the payment of the amounts then due and unpaid for
         principal of (and premium, if any) and interest on the Debt Securities
         and any coupons, 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 Debt Securities
         and any coupons for principal (and premium, if any) and interest,
         respectively. The Holders of each

                                       42
<PAGE>

         series of Debt Securities denominated in Euro, any other composite
         currency or a Foreign Currency and any matured coupons relating thereto
         shall be entitled to receive a ratable portion of the amount determined
         by the Exchange Rate Agent by converting the principal amount
         Outstanding of such series of Debt Securities and matured but unpaid
         interest on such series of Debt Securities in the currency in which
         such series of Debt Securities is denominated into Dollars at the
         Exchange Rate as of the date of declaration of acceleration of the
         Maturity of the Debt Securities; and

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

                  SECTION 507. LIMITATION ON SUITS.

                  No Holder of any Debt Securities 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 Debt
         Securities of such series;

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

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

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

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

it being understood and intended that no one or more of such Holders shall have
any right in any manner whatever by virtue of, or by availing of, any provision
of this Indenture to affect, disturb or prejudice the rights of any other such
Holders, 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 of such
Holders.

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

                  Notwithstanding any other provision in this Indenture, the
Holder of any Debt Security or coupon shall have the right which is absolute and
unconditional to receive payment of the principal of (and premium, if any) and
(subject to Section 307) interest on such Debt Security or payment of such
coupon on the respective Stated Maturity or Maturities expressed in such Debt
Security or coupon (or, in the case of redemption or repayment, on the
Redemption Date or the Repayment Date, as the case

                                       43
<PAGE>

may be) and to institute suit for the enforcement of any such payment, and such
right shall not be impaired without the consent of such Holder.

                  SECTION 509. RESTORATION OF RIGHTS AND REMEDIES.

                  If the Trustee or any Holder has instituted any proceedings 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 306, no right or
remedy herein conferred upon or reserved to the Trustee or to the Holders is
intended to be exclusive of any other right or remedy, and every right and
remedy shall, to the extent permitted by law, be cumulative and in addition to
every other right and remedy given hereunder or now or hereafter existing at law
or in equity or otherwise. The assertion or employment of any right or remedy
hereunder, or otherwise, shall not prevent the concurrent assertion or
employment of any other appropriate right or remedy.

                  SECTION 511. DELAY OR OMISSION NOT WAIVER.

                  No delay or omission of the Trustee or of any Holder of any
Debt 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 OF DEBT SECURITIES.

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

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

                  (2) subject to the provisions of Section 601, the Trustee
         shall have the right to decline to follow any such direction if the
         Trustee in good faith shall, by a Responsible Officer or Responsible
         Officers of the Trustee, determine that the proceedings so directed
         would be unjustly prejudicial to the Holders of Debt Securities of such
         series not joining in any such direction; and

                                       44
<PAGE>

                  (3) 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.

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

                  (1) in the payment of the principal of (or premium, if any) or
         interest on any Debt Security of such series, or

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

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

                  SECTION 514. UNDERTAKING FOR COSTS.

                  All parties to this Indenture agree, and each Holder of any
Debt Security or coupon 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, against any party litigant in such suit,
having a 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 Company or the Trustee, to any suit instituted by any
Holder, or group of Holders, holding in the aggregate more than 25% in principal
amount of the Outstanding Debt 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 any Debt Security or the payment of any
coupons on or after the respective Stated Maturity or Maturities expressed in
such Debt Security or coupon (or, in the case of redemption or repayment, on or
after the Redemption Date or Repayment Date, as the case may be).

                  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 or extension law
whenever 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 benefits 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.

                                   THE TRUSTEE

                  SECTION 601. CERTAIN DUTIES AND RESPONSIBILITIES.

                  Except during the continuance of an Event of Default, the
Trustee's duties and responsibilities under this Indenture shall be governed by
the Trust Indenture Act. In case an Event of Default has occurred and is
continuing, the Trustee shall exercise the rights and powers vested in it by
this Indenture, and shall use the same degree of care and skill in their
exercise, as a prudent man would exercise or use under the circumstances in the
conduct of his own affairs. Notwithstanding the foregoing, no provision of this
Indenture shall require the Trustee to expend or risk its own funds or otherwise
incur any financial liability in the performance of any of its duties hereunder,
or in the exercise of any of its rights or powers, if it shall have reasonable
grounds for believing that repayment of such funds or adequate indemnity against
such risk or liability is not reasonably assured to it. Whether or not therein
expressly so provided, every provision of this Indenture relating to the conduct
or affecting the liability of or affording protection to the Trustee shall be
subject to the provisions of this Section.

                  SECTION 602. NOTICE OF DEFAULT.

                  If a default occurs hereunder with respect to Debt Securities
of any series the Trustee shall transmit by mail to all Holders of Debt
Securities of such series notice of such default as and to the extent provided
by the Trust Indenture Act; PROVIDED, HOWEVER, that in the case of any default
of the character specified in Section 501(4) with respect to Debt Securities of
such series no such notice to Holders shall be given until at least 30 days
after the occurrence thereof. For the purpose of this Section, the term
"default" means any event which is, or after notice or lapse of time or both
would become, an Event of Default with respect to Debt Securities of such
series.

                  SECTION 603. CERTAIN RIGHTS OF TRUSTEE.

                  Except as otherwise provided in Section 601:

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

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

                  (c) whenever in the administration of this Indenture the
Trustee shall deem it desirable that a matter be proved or established prior to
taking, suffering or omitting any action

                                       46
<PAGE>

hereunder, the Trustee (unless other evidence be herein specifically prescribed)
may, in the absence of bad faith on its part, rely upon an Officers'
Certificate;

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

                  (e) the Trustee shall be under no obligation to exercise any
of the rights or powers vested in it by this Indenture at the request or
direction of any of the Holders of Debt Securities of such series or any related
coupons 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;

                  (f) the Trustee shall not be bound to make any investigation
into the facts or matters stated in any resolution, certificate, statement,
instrument, opinion, report, notice, request, direction, consent, order, bond,
debenture, note, coupon, 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, other than any such books or records containing
information as to the affairs of the customers of the Company or any of its
subsidiaries; PROVIDED that the Trustee may examine such books and records
relating to customers to the extent that such books and records contain
information as to any payments made to such customers in their capacity as
Holders of Debt Securities; provided, further, that the Trustee shall treat all
information regarding the Company which it receives pursuant to this Indenture
and its duties hereunder as confidential and shall not disclose such information
unless necessary in order to fulfill its duties under this Indenture or the
Trust Indenture Act; and

                  (g) the Trustee may execute any of the trusts or powers
hereunder or perform any duties hereunder either directly or by or through
agents or attorneys and the Trustee shall not be responsible for any misconduct
or negligence on the part of any agent or attorney appointed with due care by it
hereunder; no Exchange Rate Agent, Global Exchange Agent, Depositary or Paying
Agent shall be deemed an agent of the Trustee and the Trustee shall not be
responsible for any act or omission by any of them.

                  SECTION 604. NOT RESPONSIBLE FOR RECITALS OR ISSUANCE OF DEBT
         SECURITIES.

                  The recitals contained herein and in the Debt Securities,
except the Trustee's certificates of authentication, and in any coupons, and the
information in any registration statement, including all attachments thereto,
except information provided by the Trustee therein, shall be taken as the
statements of the Company, and the Trustee assumes no responsibility for their
correctness. The Trustee makes no representations as to the validity or
sufficiency of this Indenture or of the Debt Securities of any series or any
coupons. The Trustee shall not be accountable for the use or application by the
Company of any Debt Securities or the proceeds thereof. The Trustee shall not be
responsible for and makes no representations as to the Company's ability or
authority to issue Bearer Securities or the lawfulness thereof.

                                       47
<PAGE>

                  SECTION 605. MAY HOLD DEBT SECURITIES OR COUPONS.

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

                  SECTION 606. MONEY HELD IN TRUST.

                  Money held by the Trustee or any Paying Agent in trust
hereunder need not be segregated from other funds except to the extent required
by law. Neither the Trustee nor any Paying Agent shall be under any liability
for interest on any money received by it hereunder except as otherwise agreed
with the Company.

                  SECTION 607. COMPENSATION AND REIMBURSEMENT.

                  The Company agrees

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

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

                  (3) to indemnify the Trustee for, and to hold it harmless
         against, any loss, 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 or performance of its duties
         hereunder, including the reasonable costs and expenses of defending
         itself against any claim or liability in connection with the exercise
         or performance of any of its powers or duties hereunder.

                  The Trustee shall promptly notify the Company of any claim for
which it may seek indemnification pursuant to the provisions of this Indenture.
The Company shall be entitled to participate in, and to the extent that it shall
wish, to assume the defense of such claim, with counsel satisfactory to the
Trustee (and the Trustee shall cooperate in the defense thereof), and after
notice from the Company to the Trustee of the Company's election so to assume
the defense thereof, the Company shall not be liable to the Trustee under this
Indenture for any legal or other expenses subsequently incurred by the Trustee
in connection with the defense thereof other than reasonable costs of
investigation. The Company shall not be obligated under any settlement agreement
relating to any claim under this Indenture to which it has not agreed in
writing.

                                       48
<PAGE>

                  As security for the performance of the obligations of the
Company under this Section the Trustee shall have a claim prior to the Debt
Securities and any coupons 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 Debt Securities or any coupons.

                  The provisions of this Section 607 shall survive the
resignation or removal of the Trustee and the termination of this Indenture.

                  SECTION 608. DISQUALIFICATION; CONFLICTING INTERESTS.

                  If the Trustee has or shall acquire any conflicting interest
within the meaning of the Trust Indenture Act, the Trustee shall either
eliminate such interest or resign, to the extent and in the manner provided by,
and subject to the provisions of, the Trust Indenture Act and this Indenture. To
the extent permitted by such Act, the Trustee shall not be deemed to have a
conflicting interest with respect to Debt Securities of any series by virtue of
being a trustee under this Indenture with respect to any particular series of
Debt Securities.

                  SECTION 609. CORPORATE TRUSTEE REQUIRED; ELIGIBILITY.

                  There shall at all times be a Trustee hereunder which shall be
a corporation that is eligible pursuant to the Trust Indenture Act to act as
such and organized and doing business under the laws of the United States, any
State thereof or the District of Columbia, authorized under such laws to
exercise corporate trust powers, having a combined capital and surplus of at
least $5,000,000, and subject to supervision or examination by Federal or State
authority; PROVIDED, HOWEVER, that if Section 310(a) of the Trust Indenture Act
or the rules and regulations of the Commission under the Trust Indenture Act at
any time permit a corporation organized and doing business under the laws of any
other jurisdiction to serve as trustee of an indenture qualified under the Trust
Indenture Act, this Section 609 shall be automatically amended to permit a
corporation organized and doing business under the laws of any such other
jurisdiction to serve as Trustee hereunder. If such corporation publishes
reports of condition at least annually, pursuant to law or to the requirements
of the aforesaid supervising or examining authority, then for the purposes of
this Section, the combined capital and surplus of such 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, it shall resign
immediately in the manner and with the effect hereinafter specified in this
Article.

                  SECTION 610. RESIGNATION AND REMOVAL; APPOINTMENT OF
         SUCCESSOR.

                  (a) No resignation or removal of the Trustee and no
appointment of a successor Trustee pursuant to this Article shall become
effective until the acceptance of appointment by the successor Trustee under
Section 611.

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

                                       49
<PAGE>

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

                  (d) If at any time:

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

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

                  (3) the Trustee shall become incapable of acting with respect
         to any series of Debt Securities or a decree or order for relief by a
         court having jurisdiction in the premises shall have been entered in
         respect of the Trustee in an involuntary case under the Federal
         bankruptcy laws, as now or hereafter constituted, or any other
         applicable Federal or State bankruptcy, insolvency or similar law; or a
         decree or order by a court having jurisdiction in the premises shall
         have been entered for the appointment of a receiver, custodian,
         liquidator, assignee, trustee, sequestrator or other similar official
         of the Trustee or of its property or affairs, or any public officer
         shall take charge or control of the Trustee or of its property or
         affairs for the purpose of rehabilitation, conservation, winding up or
         liquidation, or

                  (4) the Trustee shall commence a voluntary case under the
         Federal bankruptcy laws, as now or hereafter constituted, or any other
         applicable Federal or State bankruptcy, insolvency or similar law or
         shall consent to the appointment of or taking possession by a receiver,
         custodian, liquidator, assignee, trustee, sequestrator or other similar
         official of the Trustee or its property or affairs, or shall make an
         assignment for the benefit of creditors, or shall admit in writing its
         inability to pay its debts generally as they become due, or shall take
         corporate action in furtherance of any such action,

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

                  (e) If the Trustee shall resign, be removed or become
incapable of acting with respect to any series of Debt Securities, or if a
vacancy shall occur in the office of Trustee for any cause, with respect to the
Debt Securities or one or more series, the Company, by a Board Resolution, shall
promptly appoint a successor Trustee or Trustees with respect to the Debt
Securities of that or those series (it being understood that any such successor
Trustee may be appointed with respect to the Debt 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 Debt Securities of any particular series) and shall comply with
the applicable requirements of Section 611. If, within one year after such
resignation, removal or incapability, or the

                                       50
<PAGE>

occurrence of such vacancy, a successor Trustee with respect to the Debt
Securities of any series shall be appointed by Act of the Holders of a majority
in principal amount of the Outstanding Debt Securities of such series delivered
to the Company and the retiring Trustee, the successor Trustee so appointed
shall, forthwith upon its acceptance of such appointment, become the successor
Trustee with respect to the Debt Securities of such series and to that extent
supersede the successor Trustee appointed by the Company. If no successor
Trustee with respect to the Debt 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 Debt
Security of such series for at least six months may, subject to Section 514, 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 Debt Securities of such series.

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

                  SECTION 611. ACCEPTANCE OF APPOINTMENT BY SUCCESSOR.

                  (a) In the case of an appointment hereunder of a successor
Trustee with respect to all Debt Securities, every such successor Trustee so
appointed shall execute, acknowledge and deliver to the Company and to the
retiring Trustee an instrument accepting such appointment, and thereupon the
resignation or removal of the retiring Trustee shall become effective and such
successor Trustee, without any further act, deed or conveyance, shall become
vested with all the rights, powers, trusts and duties of the retiring Trustee;
but, on 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 the case of the appointment hereunder of a successor
Trustee with respect to the Debt Securities of one or more (but not all) series,
the Company, the retiring Trustee upon payment of its charges and each successor
Trustee with respect to the Debt 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 Debt 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 Debt 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 Debt
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-

                                       51
<PAGE>

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 Debt Securities of that or those series to which the appointment of such
successor Trustee relates; but, on the 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 Debt Securities of that or those series to which the
appointment of such successor Trustee relates.

                  (c) Upon request of any such successor Trustee, the Company
shall execute any and all instruments for more fully and certainly vesting in
and confirming to such successor Trustee all such 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 612. MERGER, CONVERSION, CONSOLIDATION OR SUCCESSION
         TO BUSINESS.

                  Any corporation into which the Trustee may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which the Trustee shall be a
party, or any corporation succeeding to all or substantially all of the
corporate trust business of the Trustee, shall, with the written approval of the
Company, be the successor of the Trustee hereunder, provided such corporation
shall be otherwise qualified and eligible under this Article, without the
executing or filing of any paper or any further act on the part of any of the
parties hereto. In case any Debt Securities shall have been authenticated, but
not delivered, by the Trustee then in office, any successor by merger,
conversion, consolidation or sale to such authenticating Trustee may adopt such
authentication and deliver the Debt Securities so authenticated with the same
effect as if such successor Trustee had itself authenticated such Debt
Securities. In case any Debt Securities shall not have been authenticated by
such predecessor Trustee, any such successor Trustee may authenticate and
deliver such Debt Securities, in either its own name or that of its predecessor
Trustee, with the full force and effect which this Indenture provides for the
certificate of authentication of the Trustee. If the Trustee's successor by
merger, conversion, consolidation or sale shall not have received the written
approval of the Company, such successor shall resign within 20 days after the
merger, conversion, consolidation or sale and such vacancy in the office of the
Trustee shall be filled in the manner specified in Section 610.

                  SECTION 613. PREFERENTIAL COLLECTION OF CLAIMS AGAINST
         COMPANY.

                  If and when the Trustee shall be or shall become a creditor,
directly or indirectly, secured or unsecured, of the Company (or any other
obligor upon the Debt Securities), the Trustee shall be subject to the
provisions of the Trust Indenture Act regarding collection of claims against the
Company (or any such other obligor).

                                       52
<PAGE>

                  SECTION 614. AUTHENTICATING AGENT.

                  The Trustee may upon Company request appoint one or more
Authenticating Agents (including, without limitation, the Company or any
Affiliate thereof) with respect to one or more series of Debt Securities which
shall be authorized on behalf of the Trustee in authenticating Debt Securities
of such series in connection with the issue, delivery, registration of transfer,
exchange, partial redemption or repayment of such Debt Securities. Wherever
reference is made in this Indenture to the authentication of Debt Securities by
the Trustee or the Trustee's certificate of authentication, such reference shall
be deemed to include authentication on behalf of the Trustee by an
Authenticating Agent and a certificate of authentication executed on behalf of
the Trustee by an Authenticating Agent. Each Authenticating Agent must be
acceptable to the Company and, in the case of Registered Securities, must be a
corporation organized and doing business under the laws of the United States or
of any State or the District of Columbia, having a combined capital surplus of
at least $1,000,000, authorized under such laws to do a trust business and
subject to supervision or examination by Federal or State authorities, and in
the case of Bearer Securities and an authenticating agent who is not organized
and doing business under the laws of the United States or of any State thereof
or the District of Columbia, is subject to supervision or examination by the
appropriate foreign authorities.

                  Any corporation succeeding to the corporate agency business of
an authenticating agent shall continue to be an authenticating agent without the
execution or filing of any paper or any further act on the part of the Trustee
or such authenticating agent.

                  An authenticating agent may at any time resign with respect to
one or more series of Debt Securities by giving written notice of resignation to
the Trustee and to the Company. The Trustee may at any time terminate the agency
of any authenticating agent with respect to one or more series of Debt
Securities by giving written notice of termination 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 an authenticating agent shall cease to be
eligible in accordance with the provisions of this Section, the Trustee may
appoint a successor authenticating agent. Any successor authenticating agent
upon acceptance of its appointment hereunder shall become vested with all
rights, powers and duties of its predecessor hereunder, with like effect as if
originally named as an authenticating agent herein. No successor authenticating
agent shall be appointed unless eligible under the provisions of this Section.

                  The Trustee agrees to pay to each authenticating agent from
time to time reasonable compensation for its services under this Section, and
the Trustee shall be entitled to be reimbursed for such payment, subject to the
provisions of Section 607.

                  The provisions of Sections 104, 111, 306, 309, 603, 604 and
605 shall be applicable to any authenticating agent.

                  Pursuant to each appointment made under this Section, the Debt
Securities of each series covered by such appointment may have endorsed thereon,
in lieu of the Trustee's certificate of authentication, an alternate certificate
of authentication in substantially the following form:

                  This is one of the Debt Securities, of the series designated
herein, described in the within-mentioned Indenture.

                  (2) to add to the covenants of the Company, for the benefit of
         the Holders of all or any series of Debt Securities (and if such
         covenants are to be for the benefit of less than all series of Debt

         principal of (or premium, if any, on) Registered Securities or of
         principal of (or premium, if any, on) or any interest on Bearer

<PAGE>

         not adversely affect the interests of the Holders of Debt Securities of
         any series or any related coupons in any material respect; or

                  (5) to change or eliminate any of the provisions of this
         Indenture, PROVIDED that any such change or elimination (a) shall
         become effective only when there is no Debt Security Outstanding of any

         which is entitled to the benefit of such provisions or (b) shall not
         apply to any Debt Security Outstanding; or

         hereunder by a successor Trustee with respect to the Debt Securities of
         one or more series and to 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,
         pursuant to the requirements of Section 611(b); or

                  (9) to cure any ambiguity, to correct or supplement any
         provision herein which may be defective or inconsistent with any other
         provision herein, or to make any other provisions with respect to
         matters or questions arising under this Indenture which shall not be
         inconsistent with any provision of this Indenture, PROVIDED such other
         provisions shall not adversely affect the interests of the Holders of
         Debt Securities of any series or any related coupons in any material
         respect; or

                  (10) to add to or change or eliminate any provision of this
         Indenture as shall be necessary or desirable in accordance with any
         amendments to the Trust Indenture Act, provided such action shall not
         adversely affect the interest of Holders of Debt Securities of any
         series or any related coupons in any material respect.

                  SECTION 902. SUPPLEMENTAL INDENTURES WITH CONSENT OF HOLDERS.

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

                  (1) change the Stated Maturity of the principal or any
         installment of principal of, or any installment of interest on, any
         Debt Security, or reduce the principal amount thereof or the

                                       58
<PAGE>

         interest thereon or any premium payable upon redemption or repayment
         thereof, or change any obligation of the Company to pay additional
         amounts pursuant to Section 1006 (except as contemplated by Section
         801(1) and permitted by Section 901(1)), or reduce the amount of the
         principal of an Original Issue Discount Security that would be due and
         payable upon a declaration of acceleration of the Maturity thereof
         pursuant to Section 502, or change any Place of Payment, or the coin or
         currency in which any Debt Security or the interest thereon or any
         coupon is payable, or impair the right to institute suit for the
         enforcement of any such payment on or after the Stated Maturity thereof
         (or, in the case of redemption or repayment, on or after the Redemption
         Date or Repayment Date, as the case may be), or

                  (2) reduce the percentage in principal amount of the
         Outstanding Debt Securities of any series, the consent of whose Holders
         is required for any such supplemental indenture, or the consent of
         whose Holders is required for any waiver (of compliance with certain
         provisions of this Indenture or certain defaults hereunder and their
         consequences) provided for in this Indenture, or reduce the
         requirements of Section 1404 for quorum or voting, or

                  (3) modify any of the provisions of this Section, Section 513
         or Section 1012, except to increase any such percentage or to provide
         that certain other provisions of this Indenture cannot be modified or
         waived without the consent of the Holder of each Outstanding Debt
         Security affected thereby; PROVIDED, HOWEVER, that this clause shall
         not be deemed to require the consent of any Holder with respect to
         changes in the references to "the Trustee" and concomitant changes in
         this Section and Section 1012, or the deletion of this proviso, in
         accordance with the requirements of Section 611(b) and 901(8), or

                  (4) adversely affect the right to repayment, if any, of Debt
         Securities of any series at the option of the Holders thereof.

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

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

                  SECTION 903. EXECUTION OF SUPPLEMENTAL INDENTURES.

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

                  SECTION 904. EFFECT OF SUPPLEMENTAL INDENTURES.

                  Upon the execution of any supplemental indenture under this
Article, this Indenture shall be modified in accordance therewith, and such
supplemental indenture shall form a part of this Indenture for all purposes; and
every Holder of Debt Securities theretofore or thereafter authenticated and
delivered hereunder and of any coupons appertaining thereto shall be bound
thereby.

                  SECTION 905. CONFORMITY WITH TRUST INDENTURE ACT.

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

                  SECTION 906. REFERENCE IN DEBT SECURITIES TO SUPPLEMENTAL
         INDENTURES.

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

                                   ARTICLE TEN

                                    COVENANTS

                  SECTION 1001. PAYMENT OF PRINCIPAL, PREMIUM AND INTEREST.

                  The Company covenants and agrees for the benefit of each
series of Debt Securities and any appurtenant coupons that it will duly and
punctually pay the principal of (and premium, if any) and interest on the Debt
Securities in accordance with the terms of the Debt Securities, any appurtenant
coupons and this Indenture. Any interest due on Bearer Securities on or before
Maturity, other than additional amounts, if any, payable as provided in Section
1006 in respect of principal of (or premium, if any, on) such a Debt Security,
shall be payable only upon presentation and surrender of the coupon or coupons
for such interest installments as are evidenced thereby as they severally
mature.

                  SECTION 1002. MAINTENANCE OF OFFICE OR AGENCY.

                  The Company will maintain in each Place of Payment for any
series of Debt Securities an office or agency where Debt Securities (but, except
as otherwise provided below, unless such Place of Payment is located outside the
United States, not Bearer Securities or coupons) may be presented or surrendered
for payment, where Debt Securities may be surrendered for registration of
transfer or exchange and where notices and demands to or upon the Company in
respect of the Debt Securities and this Indenture may be served. If Debt
Securities of a series are issuable as Bearer Securities, the Company will
maintain, subject to any laws or regulations applicable thereto, an office or
agency in a Place of Payment for such series which is located outside the United
States where Debt Securities of

                                       60
<PAGE>

such series and the related coupons may be presented and surrendered for payment
(including payment of any additional amounts payable on Debt Securities of such
series pursuant to Section 1006); PROVIDED, HOWEVER, that if the Debt Securities
of such series are listed on a stock exchange located outside the United States
and such stock exchange shall so require, the Company will maintain a Paying
Agent in any required city located outside the United States, as the case may
be, so long as the Debt Securities of such series are listed on such exchange.
The Company will give prompt written notice to the Trustee of the location, and
any change in the location, of any 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 or demands may be made or served at ___________________________________,
and the Company hereby appoints ______________________________________ its agent
to receive all presentations, surrenders, notices and demands, except that
Bearer Securities of that series and the related coupons may be presented and
surrendered for payment (including payment of any additional amounts payable on
Bearer Securities of that series pursuant to Section 1006) at the place
specified for the purpose pursuant to Section 301(5).

                  No payment of principal of, or premium, if any, 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, payment of principal of and any premium and interest
(including additional amounts payable in respect thereof) on any Bearer Security
denominated in Dollars may be made at an office or agency of, and designated by,
the Company located in the United States if (but only if) payment of the full
amount of such principal, premium, interest or additional amounts in Dollars at
all offices outside the United States maintained for the purpose by the Company
in accordance with this Indenture is illegal or effectively precluded by
exchange controls or other similar restrictions and the Trustee receives an
Opinion of Counsel that such payment within the United States is legal. Unless
otherwise provided as contemplated by Section 301 with respect to any series of
Debt Securities, at the option of the Holder of any Bearer Security or related
coupon, payment may be made by check in the currency designated for such payment
pursuant to the terms of such Bearer Security presented or mailed to an address
outside the United States or by transfer to an account in such currency
maintained by the payee with a bank located outside the United States.

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

                  SECTION 1003. MONEY FOR DEBT 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 Debt Securities, it will, on or before each due
date of the principal of (and premium, if any) or interest on any of the Debt
Securities of such series, segregate and hold in trust for the benefit of the
Persons entitled thereto a sum sufficient to pay the principal (and premium, if
any) or interest 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 with
respect to any series of Debt Securities, it will, on or before each due date of
the principal of (and premium, if any) or interest on any of the Debt Securities
of such series, deposit with a Paying Agent a sum sufficient to pay the
principal (and premium, if any) or interest so becoming due, such sum to be held
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 with respect to any
series of Debt Securities other than the Trustee to execute and deliver to the
Trustee an instrument in which such Paying Agent shall agree with the Trustee,
subject to the provisions of this Section, that such Paying Agent will

                  (1) hold all sums held by it for the payment of the principal
         of (and premium, if any) or interest on Debt 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 Debt Securities of such series or any
         appurtenant coupons) in the making of any payment of principal of (and
         premium, if any) or interest on the Debt 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 terminating
its obligations under this Indenture with respect to Debt Securities of any
series or for any other purpose, pay, or by Company Order direct any Paying
Agent to pay, to the Trustee all sums held in trust by the Company or such
Paying Agent, such sums to be held by the Trustee upon the same trusts as those
upon which such sums were held by the Company or such Paying Agent; and, upon
such payment by any Paying Agent to the Trustee, such Paying Agent shall be
released from all further liability with respect to such money.

                  Any principal and interest received on the Government
Obligations deposited with the Trustee or any money deposited with the Trustee
or any Paying Agent, or then held by the Company, in trust for the payment of
the principal of (and premium, if any) or interest on any Debt Security of any
series or any money on deposit with the Trustee or any Paying Agent representing
amounts deducted from the Redemption Price or Repayment Price with respect to
unmatured coupons not presented upon redemption or exercise of the Holder's
option for repayment pursuant to Section 1106 or 1303 and remaining unclaimed
for two years after such principal (and premium, if any) or interest has become
due and payable shall be paid to the Company on Company Request, or (if then
held by the Company) shall be discharged from such trust; and the Holder of such
Debt Security or any coupon appertaining thereto shall thereafter, as an
unsecured general creditor, look only to the Company for payment thereof, and
all liability of the Trustee or such Paying Agent with respect to such trust
money (including the principal and interest received on Government Obligations
deposited with the Trustee), and all

                                       62
<PAGE>

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 of general circulation in the Borough of
Manhattan, The City of New York, and each Place of Payment or mailed to each
such Holder, or both, notice that such money remains unclaimed and that, after a
date specified therein, which shall not be less than 30 days from the date of
such publication or mailing, any unclaimed balance of such money then remaining
will be repaid to the Company.

                  SECTION 1004. CORPORATE EXISTENCE.

                  Subject to Article Eight, the Company will do or cause to be
done all things necessary to preserve and keep in full force and effect its
corporate existence, rights (charter and statutory) and franchises, PROVIDED,
HOWEVER, that the Company shall not be required to preserve any such right or
franchise if the Board of Directors shall determine that the preservation
thereof is no longer desirable in the conduct of the business of the Company and
that the loss thereof is not disadvantageous in any material respect to the
Holders.

                  SECTION 1005. MAINTENANCE OF PROPERTIES.

                  The Company will cause all properties used or useful in the
conduct of its business or the business of any Subsidiary to be maintained and
kept in good condition, repair and working order and supplied with all necessary
equipment and will cause to be made all necessary repairs, renewals,
replacements, betterments and improvements thereof, all as in the judgment of
the Company may be necessary so that the business carried on in connection
therewith may be properly and advantageously conducted at all times, PROVIDED,
HOWEVER, that nothing in this Section shall prevent the Company from
discontinuing the operation or maintenance of any of such properties if such
discontinuance is, in the judgment of the Company, desirable in the conduct of
its business or the business of any Subsidiary and not disadvantageous in any
material respect to the Holders.

                  SECTION 1006. PAYMENT OF ADDITIONAL AMOUNTS.

                  If the Debt Securities of a series provide for the payment of
additional amounts, the Company will pay to the Holder of any Debt Security of
any series or any coupon appertaining thereto additional amounts upon the terms
and subject to the conditions provided therein. Whenever in this Indenture there
is mentioned, in any context, the payment of the principal of (or premium, if
any) or interest on, or in respect of, any Debt Security of any series or the
net proceeds received on the sale or exchange of any Debt Security of any
series, such mention shall be deemed to include mention of the payment of
additional amounts provided for in the terms of such Debt Securities and this
Section to the extent that, in such context, additional amounts are, were or
would be payable in respect thereof pursuant to the provisions of this Section
and express mention of the payment of additional amounts (if applicable) in any
provisions hereof shall not be construed as excluding additional amounts in
those provisions hereof where such express mention is not made.

                  If the Debt Securities of a series provide for the payment of
additional amounts, at least 10 days prior to the first Interest Payment Date
with respect to that series of Debt Securities (or if the Debt Securities of
that series will not bear interest prior to Maturity, the first day on which a
payment of principal (and premium, if any) is made), and at least 10 days prior
to each date of payment of principal

                                       63
<PAGE>

(and premium, if any) or interest if there has been any change with respect to
the matters set forth in the below-mentioned Officers' Certificate, the Company
will furnish the Trustee and the Company's principal Paying Agent or Paying
Agents, if other than the Trustee, with an Officers' Certificate instructing the
Trustee and such Paying Agent or Paying Agents whether such payment of principal
of (and premium, if any) or interest on the Debt Securities of that series shall
be made to Holders of Debt Securities of that series or the related coupons who
are United States Aliens without withholding for or on account of any tax,
assessment or other governmental charge described in the Debt Securities of that
series. If any such withholding shall be required, then such Officers'
Certificate shall specify by country the amount, if any, required to be withheld
on such payments to such Holders of Debt Securities or coupons and the Company
will pay to the Trustee or such Paying Agent the additional amounts, if any,
required by the terms of such Debt Securities and the first paragraph of this
Section. The Company covenants to indemnify the Trustee and any Paying Agent
for, and to hold them harmless against, any loss, liability or expense
reasonably incurred without negligence or bad faith on their part arising out of
or in connection with actions taken or omitted by any of them in reliance on any
Officers' Certificate furnished pursuant to this Section.

                  SECTION 1007. PAYMENT OF TAXES AND OTHER CLAIMS.

                  The Company will pay or discharge or cause to be paid or
discharged, before the same shall become delinquent, (1) all taxes, assessments
and governmental charges levied or imposed upon the Company or any Subsidiary or
upon the income, profits or property of the Company or any Subsidiary, and (2)
all lawful claims for labor, materials and supplies which, if unpaid, might by
law become a lien upon the property of the Company or any 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, charge or claim whose amount,
applicability or validity is being contested in good faith by appropriate
proceedings.

                  SECTION 1008. RESTRICTION ON THE CREATION OF SECURED FUNDED
         DEBT.

                  (a) The Company will not, and will not permit any Restricted
Subsidiary to, issue, assume or guarantee, incur or create any Secured Funded
Debt unless immediately thereafter the sum of (i) the aggregate principal amount
of all outstanding Secured Funded Debt of the Company and its Restricted
Subsidiaries (exclusive of any Secured Funded Debt permitted by paragraph (b) of
this Section) plus (ii) the aggregate amount of all Attributable Debt of the
Company and its Restricted Subsidiaries in respect of sale and leaseback
transactions (as defined in Section 1009) does not exceed 15% of Consolidated
Net Tangible Assets.

                  (b) Compliance with the requirements of Section 1008(a) shall
be determined without regard to (i) Secured Funded Debt of a Restricted
Subsidiary owing to the Company or a Wholly-owned Restricted Subsidiary, (ii)
Secured Funded Debt resulting from the Mortgage of property of the Company or
any Restricted Subsidiary in favor of the United States, or any State thereof,
or any department, agency or instrumentality of the United States or any State
thereof, to secure partial, progress, advance or other payments to the Company
or any Restricted Subsidiary pursuant to the provisions of any contract or
statute, (iii) Secured Funded Debt resulting from Mortgages on property of, or
on any shares of stock or Indebtedness of, any corporation existing at the time
such corporation becomes a Subsidiary, (iv) subject to Section 801, Secured
Funded Debt resulting from Mortgages on property, shares of stock or
Indebtedness existing at the time of acquisition thereof

                                       64
<PAGE>

(including acquisition through merger or consolidation) or to secure the payment
of all or any part of the purchase price or construction cost thereof or to
secure any indebtedness incurred prior to, at the time of, or within 120 days
after, the acquisition of such property or shares or Indebtedness or the
completion of any such construction for the purpose of financing all or any part
of the purchase price or construction cost thereof, (v) Secured Funded Debt
resulting from Mortgages incurred or assumed in connection with an issuance of
revenue bonds the interest on which is exempt from Federal income tax pursuant
to section 103(b) of the Internal Revenue Code of 1986, as amended (or any
predecessor or successor provision thereof), or (vi) any extension, renewal or
refunding (or successive extensions, renewals or refundings), in whole or in
part (but without increase in amount), of any Secured Funded Debt (and of any
Mortgage securing the same) permitted by the provisions of paragraph (a) of this
Section 1008 or of any Secured Funded Debt (and of any Mortgage securing the
same) outstanding at December 31, 1999 of those Subsidiaries which will
constitute Restricted Subsidiaries upon the execution and delivery of this
Indenture as originally executed or of any Secured Funded Debt (and of any
Mortgage securing the same) of any corporation outstanding at the time such
corporation became a Restricted Subsidiary, PROVIDED that the Mortgage securing
such extended, renewed or refunded Secured Funded Debt is limited to the same
property (plus improvements thereon) that secured the Secured Funded Debt so
extended, renewed or refunded immediately prior thereto.

                  (c) Notwithstanding the foregoing paragraphs of this Section,
the Company or any Restricted Subsidiary may issue, assume, guarantee, incur or
create Secured Funded Debt not permitted by such paragraphs if the Company shall
first make effective provision whereby the Debt Securities (together with, if
the Company shall so determine, any other Indebtedness or any obligations of the
Company or such Restricted Subsidiary then existing or thereafter created
ranking equally with the Debt Securities, including guarantees of Indebtedness
or obligations of others) shall be secured equally and ratably with (or prior
to) such Secured Funded Debt, so long as such Secured Funded Debt shall be so
secured. If the Company shall hereafter make provision to secure the Debt
Securities equally and ratably with (or prior to) any other Indebtedness or
obligations pursuant to this paragraph (c), then (i) the Company will promptly
deliver to the Trustee an Officers' Certificate and Opinion of Counsel stating
that this paragraph (c) has been complied with and that any instruments executed
by the Company or any Restricted Subsidiary in the performance of this paragraph
(c) comply with the requirements hereof, and (ii) the Trustee is hereby
authorized to enter into an indenture or agreement supplemental hereto and to
take such action, if any, as it may deem advisable to enable it to enforce the
rights of the Holders of the Debt Securities as so secured.

                  SECTION 1009. RESTRICTION ON SALE AND LEASE-BACK TRANSACTIONS.

                  The Company will not itself, and it will not permit any
Restricted Subsidiary to, enter into any arrangement with any bank, insurance
company or other lender or investor (not including the Company or any Restricted
Subsidiary) or to which any such lender or investor is a party, providing for
the leasing by the Company or any Restricted Subsidiary for a period, including
renewals, in excess of three years of any Principal Property which has been or
is to be sold or transferred, more than 120 days after the acquisition thereof
or the completion of construction and commencement of full operation thereof, by
the Company or any Restricted Subsidiary to such lender or investor or to any
person to whom funds have been or are to be advanced by such lender or investor
on the security of such Principal Property (herein referred to as a "sale and
leaseback transaction") unless either:

                                       65
<PAGE>

                  (1) the Company or such Restricted Subsidiary could create
         Secured Funded Debt pursuant to Section 1008 on the Principal Property
         to be leased back in an amount equal to the Attributable Debt with
         respect to such sale and leaseback transaction without equally and
         ratably securing the Debt Securities, or

                  (2) the Company, within 120 days after the sale or transfer
         shall have been made by the Company or by any such Restricted
         Subsidiary, applies an amount equal to the greater of (i) the net
         proceeds of the sale of the Principal Property sold and leased back
         pursuant to such arrangement or (ii) the fair market value of the
         Principal Property so sold and leased back at the time of entering into
         such arrangements (as determined by any two of the following: the
         Chairman of the Board of the Company, its Chief Executive Officer, its
         President, any Vice President of the Company, its Treasurer and its
         Controller) to the retirement of Secured Funded Debt of the Company,
         PROVIDED that the amount to be applied to the retirement of Secured
         Funded Debt of the Company shall be reduced by (a) the principal amount
         of any Debt Securities delivered within 120 days after such sale to the
         Trustee for retirement and cancellation, and (b) the principal amount
         of Secured Funded Debt voluntarily retired by the Company within 120
         days after such sale. Notwithstanding the foregoing, no retirement
         referred to in this clause (2) may be effected by payment at maturity
         or pursuant to any mandatory sinking fund payment or any mandatory
         prepayment provision.

                  SECTION 1010. RESTRICTION ON PERMITTING UNRESTRICTED
         SUBSIDIARIES TO BECOME RESTRICTED SUBSIDIARIES.

                  (a) The Company will not permit any Unrestricted Subsidiary to
be designated as a Restricted Subsidiary unless such Subsidiary has outstanding
no Secured Funded Debt and/or Attributable Debt except such Secured Funded Debt
and Attributable Debt as the Company could permit it to become liable for
immediately after becoming a Restricted Subsidiary under the provisions of
Section 1008.

                  (b) Promptly after the adoption of any Board Resolution
designating an Unrestricted Subsidiary as a Restricted Subsidiary, a copy
thereof shall be filed with the Trustee, together, in the case of the
designation of an Unrestricted Subsidiary as a Restricted Subsidiary, with an
Officers' Certificate stating that the provisions of this Section have been
complied with in connection with such designation.

                  SECTION 1011. OFFICER'S CERTIFICATE AS TO DEFAULT.

                  The Company will furnish to the Trustee not more than 120 days
after the end of the Company's fiscal year in each year (beginning with 2001) a
brief certificate from the principal executive, financial or accounting officer
or treasurer or controller of the Company as to his or her knowledge of the
Company's compliance with all conditions and covenants under this Indenture
(such compliance to be determined without regard to any period of grace or
requirement of notice provided under this Indenture), and, if he or she has
knowledge of any default, specifying each such default of which the signer has
knowledge and the nature thereof.

                  SECTION 1012. WAIVER OF CERTAIN COVENANTS.

                  The Company may omit in any particular instance to comply with
any covenant or condition set forth in Sections 1004, 1005 and 1007 to 1010
inclusive with respect to the Debt Securities of any series if, before the time
for such compliance the Holders of at least a majority in principal amount of
the Debt Securities at the time Outstanding shall, by Act of such Holders,
either waive such compliance in such instance or generally waive compliance with
such covenant or condition, but no such waiver shall extend to or affect such
covenant or condition except to the extent so expressly waived, and, until such
waiver shall become effective, the obligations of the Company and the duties of
the Trustee in respect of any such covenant or condition shall remain in full
force and effect.

                          REDEMPTION OF DEBT SECURITIES

                  SECTION 1101. APPLICABILITY OF ARTICLE.

                  Debt Securities of any series which are redeemable before
their Stated Maturity shall be redeemable in accordance with their terms and
(except as otherwise specified as contemplated by Section 301 for Debt
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 Debt Securities
shall be evidenced by a Board Resolution. In case of any redemption at the
election of the Company of less than all of the Debt Securities of any series,
the Company shall, at least 45 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 and the tenor
and terms of the Debt Securities of any series to be redeemed. In the case of
any redemption of Debt Securities prior to the expiration of any restriction on
such redemption provided in the terms of such Debt 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 DEBT SECURITIES TO BE
         REDEEMED.

                  Except as otherwise specified as contemplated by Section 301
for Debt Securities of any series, if less than all the Debt Securities of any
series with like tenor and terms are to be redeemed, the particular Debt
Securities to be redeemed shall be selected not more than 60 days prior to the
Redemption Date by the Trustee, from the Outstanding Debt Securities of such
series with like tenor and terms 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 (equal to the minimum authorized
denomination for Debt Securities of such series or any integral multiple thereof
which is also an authorized denomination) of the principal amount of Registered
Securities or Bearer Securities (if issued in more than one authorized
denomination) of such series of a denomination larger than the minimum
authorized denomination for Debt Securities of such series.

                                       67
<PAGE>

                  The Trustee shall promptly notify the Company in writing of
the Debt Securities selected for redemption and, in the case of any Debt
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 Debt Securities
shall relate, in the case of any Debt Security redeemed or to be redeemed only
in part, to the portion of the principal amount of such Debt Security which has
been or is to be redeemed.

                  SECTION 1104. NOTICE OF REDEMPTION.

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

                  All notices of redemption shall state:

                  (1) the Redemption Date,

                  (2) the Redemption Price,

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

                  (4) that on the Redemption Date the Redemption Price will
         become due and payable upon each such Debt Security to be redeemed, and
         that interest thereon shall cease to accrue on and after said date,

                  (5) the Place or Places of Payment where such Debt Securities,
         together in the case of Bearer Securities with all coupons, if any,
         appertaining thereto maturing after the Redemption Date, are to be
         surrendered for payment of the Redemption Price,

                  (6) that Bearer Securities may be surrendered for payment only
         at such place or places which are outside the United States, except as
         otherwise provided in Section 1002,

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

                  (8) the CUSIP number, if any.

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

                  Notice of redemption of Debt 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.

                  On or prior to any Redemption Date, the Company shall deposit
with the Trustee or with a Paying Agent (or, if the Company is acting as its own
Paying Agent, segregate and hold in trust as provided in Section 1003) an amount
of money and/or Government Obligations the payments of principal and interest on
which when due (and without reinvestment) will provide money on or prior to the
Redemption Date in such amounts as will (together with any money irrevocably
deposited in trust with the Trustee, without investment) be sufficient to pay
the Redemption Price of, and (except if the Redemption Date shall be an Interest
Payment Date) accrued interest on, all the Debt Securities or portions thereof
which are to be redeemed on that date; PROVIDED, HOWEVER, that deposits with
respect to Bearer Securities shall be made with a Paying Agent or Paying Agents
located outside the United States except as otherwise provided in Section 1002,
unless otherwise specified as contemplated by Section 301.

                  SECTION 1106. DEBT SECURITIES PAYABLE ON REDEMPTION DATE.

                  Notice of redemption having been given as aforesaid, the Debt
Securities to be redeemed shall, on the Redemption Date, become due and payable
at the Redemption Price therein specified and from and after such date (unless
the Company shall default in the payment of the Redemption Price and accrued
interest) such Debt Securities shall cease to bear interest and the coupons for
such interest appertaining to any Bearer Securities so to be redeemed, except to
the extent provided below, shall be void. Upon surrender of any such Debt
Security for redemption in accordance with said notice, such Debt Security shall
be paid by the Company at the Redemption Price, together with accrued interest
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 upon presentation and surrender of coupons for such
interest (at an office or agency located outside the United States except as
otherwise provided in Section 1002), 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 Debt Securities, or one
or more Predecessor Securities, registered as such on the relevant Record Dates
according to their terms and the provisions of Section 307.

                  If any Bearer Security surrendered for redemption shall not be
accompanied by all appurtenant coupons maturing after the Redemption Date, such
Bearer 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 Bearer
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 without
interest thereon; PROVIDED, HOWEVER, that interest represented by coupons shall
be payable only upon presentation and surrender of those coupons at an office or
agency located outside of the United States except as otherwise provided in
Section 1002.

                  If any Debt 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 prescribed
therefor in the Debt Security.

                  SECTION 1107. DEBT SECURITIES REDEEMED IN PART.

                  Any Registered Security which is to be redeemed only in part
shall be surrendered at a Place of Payment therefor (with, if the Company, the
Security Registrar or the Trustee so requires, due endorsement by, or a written

                                 ARTICLE TWELVE

                                  SINKING FUNDS

                  SECTION 1201. APPLICABILITY OF ARTICLE.

                  The provisions of this Article shall be applicable to any
sinking fund for the retirement of Debt Securities of a series except as
otherwise specified as contemplated by Section 301 for Debt Securities of such
series.

                  The minimum amount of any sinking fund payment provided for by
the terms of Debt 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 Debt Securities of any series is herein referred to an
"optional sinking fund payment". If provided for by the terms of Debt Securities
of any series, the amount of any sinking fund payment may be subject to
reduction as provided in Section 1202. Each sinking fund payment shall be
applied to the redemption of Debt Securities of any series as provided for by
the terms of Debt Securities of such series.

                  SECTION 1202. SATISFACTION OF SINKING FUND PAYMENTS WITH DEBT
         SECURITIES.

                  The Company (1) may deliver Outstanding Debt Securities of a
series (other than any previously called for redemption), together in the case
of any Bearer Securities of such series with all unmatured coupons appertaining
thereto, and (2) may apply as a credit Debt Securities of a series which have
been redeemed either at the election of the Company pursuant to the terms of
such Debt Securities or through the application of permitted optional sinking
fund payments pursuant to the terms of such Debt Securities, in each case in
satisfaction of all or any part of any sinking fund payment with respect to the
Debt Securities of such series required to be made pursuant to the terms of such
Debt Securities as provided for by the terms of such series; PROVIDED that such
Debt Securities have not been previously so credited. Such Debt Securities shall
be received and credited for such purpose by the Trustee at the Redemption Price
specified in such Debt Securities for redemption through operation of the
sinking fund and the amount of such sinking fund payment shall be reduced
accordingly. If as a result of the delivery or credit of Debt Securities in lieu
of cash payments pursuant to this Section 1202, the principal amount of Debt
Securities to be redeemed in order to exhaust the aforesaid cash payment shall

                                       70
<PAGE>

be less than $100,000, the Trustee need not call Debt Securities for redemption,
except upon Company Request, and such cash payment shall be held by the Trustee
or a Paying Agent and applied to the next succeeding sinking fund payment,
PROVIDED, HOWEVER, that the Trustee or such Paying Agent shall at the request of
the Company from time to time pay over and deliver to the Company any cash
payment so being held by the Trustee or such Paying Agent upon delivery by the
Company to the Trustee of Debt Securities purchased by the Company having an
unpaid principal amount equal to the cash payment requested to be released to
the Company.

                  SECTION 1203. REDEMPTION OF DEBT SECURITIES FOR SINKING FUND.

                  Not less than 45 days prior to each sinking fund payment date
for any series of Debt Securities (unless a shorter period shall be satisfactory
to the Trustee), 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, the portion thereof, if any, which
is to be satisfied by crediting Debt Securities of that series pursuant to
Section 1202 and the basis for any such credit and, prior to or concurrently
with the delivery of such Officers' Certificate, will also deliver to the
Trustee any Debt Securities to be so credited and not theretofore delivered to
the Trustee. Not less than 30 days (unless a shorter period shall be
satisfactory to the Trustee) before each such sinking fund payment date the
Trustee shall select the Debt 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 Debt Securities shall be made upon the terms and in the
manner stated in Sections 1105, 1106 and 1107.

                                ARTICLE THIRTEEN

                       REPAYMENT AT THE OPTION OF HOLDERS

                  SECTION 1301. APPLICABILITY OF ARTICLE.

                  Debt Securities of any series which are repayable at the
option of the Holders thereof before their Stated Maturity shall be repaid in
accordance with their terms and (except as otherwise specified pursuant to
Section 301 for Debt Securities of such series) in accordance with this Article.

                  SECTION 1302. REPAYMENT OF DEBT SECURITIES.

                  Each Debt Security which is subject to repayment in whole or
in part at the option of the Holder thereof on a Repayment Date shall be repaid
at the applicable Repayment Price together with interest accrued to such
Repayment Date as specified pursuant to Section 301.

                  SECTION 1303. EXERCISE OF OPTION; NOTICE.

                  Each Holder desiring to exercise such Holder's option for
repayment shall, as conditions to such repayment, surrender the Debt Security to
be repaid in whole or in part together with written notice of the exercise of
such option at any office or agency of the Company in a Place of

                                       71
<PAGE>

Payment, not less than 30 nor more than 45 days prior to the Repayment Date;
PROVIDED, HOWEVER, that surrender of Bearer Securities together with written
notice of exercise of such option shall be made at an office or agency located
outside the United States except as otherwise provided in Section 1002. Such
notice, which shall be irrevocable, shall specify the principal amount of such
Debt Security to be repaid, which shall be equal to the minimum authorized
denomination for such Debt Security or an integral multiple thereof, and shall
identify the Debt Security to be repaid and, in the case of a partial repayment
of the Debt Security, shall specify the denomination or denominations of the
Debt Security or Debt Securities of the same series to be issued to the Holder
for the portion of the principal of the Debt Security surrendered which is not
to be repaid.

                  If any Bearer Security surrendered for repayment shall not be
accompanied by all unmatured coupons and all matured coupons in default, such
Bearer Security may be paid after deducting from the Repayment 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 Bearer
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 Repayment
Price, such Holder shall be entitled to receive the amount so deducted without
interest thereon; 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.

                  The Company shall execute and the Trustee shall authenticate
and deliver without service charge to the Holder of any Registered Security so
surrendered a new Registered Security or Securities of the same series, of any
authorized denomination specified in the foregoing notice, in an aggregate
principal amount equal to any portion of the principal of the Registered
Security so surrendered which is not to be repaid.

                  The Company shall execute and the Trustee shall authenticate
and deliver without service charge to the Holder of any Bearer Security so
surrendered a new Registered Security or Securities or new Bearer Security or
Securities (and all appurtenant unmatured coupons and matured coupons in
default) or any combination thereof of the same series of any authorized
denomination or denominations specified in the foregoing notice, in an aggregate
principal amount equal to any portion of the principal of the Debt Security so
surrendered which is not to be paid; PROVIDED, HOWEVER, that the issuance of a
Registered Security therefor shall be subject to applicable laws and
regulations, including provisions of the United States Federal income tax laws
and regulations in effect at the time of the exchange; neither the Company, the
Trustee nor the Security Registrar shall issue Registered Securities for Bearer
Securities if it has received an Opinion of Counsel that as a result of such
issuance the Company would suffer adverse consequences under the United States
Federal income tax laws then in effect and the Company has delivered to the
Trustee a Company Order directing the Trustee not to make such issuances
thereafter unless and until the Trustee receives a subsequent Company Order to
the contrary. The Company shall deliver copies of such Company Order to the
Security Registrar.

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

                  SECTION 1304. ELECTION OF REPAYMENT BY REMARKETING ENTITIES.

                  The Company may elect, with respect to Debt Securities of any
series which are repayable at the option of the Holders thereof before their
Stated Maturity, at any time prior to any Repayment Date to designate one or
more Remarketing Entities to purchase, at a price equal to the Repayment Price,
Debt Securities of such series from the Holders thereof who give notice and
surrender their Debt Securities in accordance with Section 1303.

                  SECTION 1305. SECURITIES PAYABLE ON THE REPAYMENT DATE.

                  Notice of exercise of the option of repayment having been
given and the Debt Securities so to be repaid having been surrendered as
aforesaid, such Debt Securities shall, unless purchased in accordance with
Section 1304, on the Repayment Date become due and payable at the price therein
specified and from and after the Repayment Date such Debt Securities shall cease
to bear interest and shall be paid on the Repayment Date, and the coupons for
such interest appertaining to Bearer Securities so to be repaid, except to the
extent provided above, shall be void, unless the Company shall default in the
payment of such price in which case the Company shall continue to be obligated
for the principal amount of such Debt Securities and shall be obligated to pay
interest on such principal amount at the rate borne by such Debt Securities from
time to time until payment in full of such principal amount.

           MINNESOTA MINING AND MANUFACTURING COMPANY, a corporation duly
organized and existing under the laws of the State of Delaware (hereinafter
called the "Company", which term includes any successor corporation under the
Indenture hereinafter referred to), for value received, hereby promises to pay
to __________________, or registered assigns, the principal sum of _____________
Dollars ($______________) on the Stated Maturity Date shown above (except to the
extent redeemed or repaid prior to such date) and to pay interest, if any, on
the principal amount hereof at the Interest Rate shown above (computed on the
basis of a 360-day year of twelve 30-day months), semi-annually on each Interest
Payment Date set forth above from and after the date of this Security and at
Maturity until payment of the principal amount hereof has been made or duly
provided for. Unless this Security is a Security which has been issued upon
transfer of, in exchange for, or in replacement of, a Predecessor Security,
interest on this Security shall accrue from the Original Issue Date indicated
above. If this Security has been issued upon transfer of, in exchange for, or in
replacement of, a Predecessor Security, interest on this Security shall accrue
from the last Interest Payment Date to which interest was paid on such
Predecessor Security or, if no interest was paid on such Predecessor Security,
from the Original Issue Date indicated above. The first payment of interest on a
Security originally issued and dated between a Regular Record Date specified
above and an Interest Payment Date will be due and payable on the Interest
Payment Date following the next succeeding Regular Record Date to the registered
owner on such next succeeding Regular Record Date. Subject to certain exceptions
provided in the Indenture referred to herein below, the interest so payable on
any Interest Payment Date will be paid to the Person in whose name this Security
is registered at the close of business on the Regular Record Date (whether or
not a Business Day) next preceding such Interest Payment Date, and interest
payable upon Maturity will be paid to the person to whom principal is payable.

           Notwithstanding the foregoing, if an addendum is attached hereto or
"Other/Additional Terms" apply to this Security as specified above, this
Security shall be subject to the terms set forth in such Addendum or such
"Other/Additional Terms."

           The principal (and premium, if any) and interest on, this Security is
payable by the Company in the specified currency specified above.

           Any interest not punctually paid or duly provided for will forthwith
cease to be payable to the Holder on such Regular Record Date and may either be
paid to the Person in whose name this Security (or one or more Predecessor
Securities) is registered at the close of business on a Special Record Date for
the payment of such Defaulted Interest to be fixed by the Trustee, notice
whereof shall be given to Holders of Securities of this series not less than 10
days prior to such Special Record Date, or be paid at any time in any other
lawful manner not inconsistent with the requirements of any securities exchange
on which the Securities of this series may be listed, and upon such notice as
may be required by such exchange, all as more fully provided in the Indenture.

           Until this Security is paid in full or payment therefor in full is
duly provided for, the Company will at all times maintain a Paying Agent (which
Paying Agent may be the Trustee)

________________________ as the Paying Agent at its offices at ________________.

           If this Security is a Global Security: Payments of principal and any
premium and interest on this Security will be made to DTC or its nominee, as
Holder of this Security, by wire transfer of immediately available funds.

           If this Security is not a Global Security: Payment of interest on
this Security (other than payments of interest at Maturity) will be made by
check mailed to the Person entitled thereto at such Person's last address as it
appears in the Security Register or, in the case of a Holder of $50,000,000 or
more in aggregate principal amount of Securities of this series, by wire
transfer of immediately available funds to such account as may have been
designated by such Holder. Any such designation for wire transfer purposes shall
be made by filing the appropriate information with the Paying Agent at its
corporate trust office not later than 15 calendar days prior to the applicable
Interest Payment Date and, unless revoked by written notice to the Paying Agent
received by the Paying Agent on or prior to the Regular Record Date immediately
preceding the applicable Interest Payment Date, shall remain in effect with
respect to any further payments with respect to this Security payable to such
Holder. Payment of principal of and interest, if any, on this Security at
Maturity will be made against presentation of this Security at the office or
agency of the Company maintained for that purpose in _____________ or
_____________.

           The Company will pay any administrative costs imposed by banks on
payors in making payments on this Security in immediately available funds and
the Holder of this Security will pay any administrative costs imposed by banks
on payees in connection with such payments. Any tax, assessment or governmental
charge imposed upon payments on this Security will be borne by the Holder of
this Security.

           Any payment on this Security due on any day which is not a Business
Day need not be made on such day, but may be made on the next succeeding
Business Day with the same force and effect as if made on the due date and no
additional interest shall accrue on the amount so payable for the period from
and after such date. For purposes of this Security, "Business Day" means any day
other than a Saturday, Sunday or a legal holiday or a day on which banking
institutions are authorized or required by law or regulation to close in
_____________ or _______________.

           Reference is hereby made to the further provisions of this Security
set forth on the reverse hereof, which further provisions shall for all purposes
have the same effect as if set forth at this place.

           Unless the certificate of authentication hereon has been executed by
the Trustee referred to on the reverse hereof by manual signature, this Security
shall not be entitled to any benefit under the Indenture or be valid or
obligatory for any purpose.
