      for every purpose hereunder (unless otherwise herein expressly provided)
      if in writing and mailed, first-class postage prepaid or airmail postage
      prepaid if sent from outside the United States, to the Company addressed
      to it at the address of its principal office specified in the first
      paragraph of this instrument, to the attention of its Treasurer or Chief
      Financial Officer, or at any other address previously furnished in writing

      SECTION 1.5. NOTICE TO HOLDERS; WAIVER.

      When this Indenture provides for notice to Holders of any event, (1) such
notice shall be sufficiently given to Registered Holders (unless otherwise
herein expressly provided) if in writing and mailed, first-class postage
prepaid, to such Registered Holders as their names and addresses appear in the
Security Register, within the time prescribed, and (2) such notice shall be
sufficiently given to Holders of Bearer Securities or Coupons (unless otherwise
herein expressly provided) if published at least twice in an Authorized
Newspaper or Newspapers in The City of New York and, if Debt Securities of such
series are then listed on The Stock Exchange of the United Kingdom and the
Republic of Ireland or the Luxembourg Stock Exchange or any other stock exchange
located outside the United States and such stock exchange shall so require, in a
daily newspaper in London or Luxembourg or in such other city or cities
specified pursuant to Section 3.1 or in any Debt Security on Business Days, the
first such publication to be not earlier than the earliest date and not later
than two Business Days prior to the latest date prescribed for the giving of
such notice; provided, however, that, in any case, any notice to Holders of
Floating Rate Securities regarding the determination of a periodic rate of
interest, if such notice is required pursuant to Section 3.1, shall be
sufficiently given if given in the manner specified pursuant to Section 3.1.

      In the event of suspension of regular mail service or by reason of any
other cause it shall be impracticable to give notice by mail, such notification
as the Company shall reasonably determine be given with the approval of the
Trustee shall constitute sufficient notice for every purpose hereunder.

      In the event of suspension of publication of any Authorized Newspapers or
by reason of any other cause it shall be impracticable to give notice by
publication, such notification as shall be given with the approval of the
Trustee shall constitute sufficient notice for every purpose hereunder.

      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 on such waiver. In any case where notice to Holders is given by mail,
neither the failure to mail such notice nor any defect in any notice so mailed
to any particular Holder shall affect the sufficiency of such notice with
respect to other Holders, and any notice which is mailed in the manner herein
provided shall be conclusively presumed to have been duly given. In any case
where notice to Holders is given by publication, any defect in any notice so
published as to any particular Holder shall not affect the sufficiency of such
notice with respect to other Holders, and any notice which is published in the
manner herein provided shall be conclusively presumed to have been duly given.

      SECTION 1.6. CONFLICT WITH TRUST INDENTURE ACT.

      This Indenture is subject to, and shall be governed by, the provisions of
the Trust Indenture Act. If any provision hereof limits, qualifies or conflicts
with the duties imposed on

                                       14
<PAGE>

any person by the provisions of Sections 310 to 317, inclusive, of the Trust
Indenture Act, such imposed duties shall control.

      SECTION 1.7. EFFECT OF HEADINGS AND TABLE OF CONTENTS.

      The Article and Section headings herein and in the Table of Contents are

      SECTION 1.8. SUCCESSORS AND ASSIGNS.

      The Company shall have the right at all times to assign any of its
respective rights or obligations under the Indenture to a direct or indirect
wholly owned Subsidiary of the Company, provided that, in the event of any such
assignment, the Company shall remain liable for such obligations. All covenants
and agreements in this Indenture by the parties hereto shall bind their
respective successors and assigns and inure to the benefit of their permitted
successors and assigns, whether so expressed or not.

      SECTION 1.9. SEPARABILITY CLAUSE.

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

      SECTION 1.10. BENEFITS OF INDENTURE.

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

      SECTION 1.11. GOVERNING LAW.

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

      SECTION 1.12. LEGAL HOLIDAYS.

      Unless otherwise specified pursuant to Section 3.1 or in any Debt
Security, in any case where any Interest Payment Date, Redemption Date or Stated
Maturity of any Debt Security of any series shall not be a Business Day at any
Place of Payment for the Debt Securities of that series, then (notwithstanding
any other provision of this Indenture or of the Debt Securities or Coupons)
payment of principal (and premium, if any) or interest 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 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 or Stated Maturity, as the case may
be, to such Business Day if such payment is made or duly provided for on such
Business Day.

      SECTION 1.13. NO SECURITY INTEREST CREATED.

      Nothing in this Indenture or in the Debt Securities or Coupons, express or
implied, shall be construed to constitute a security interest under the Uniform
Commercial Code or similar legislation, as now or hereafter enacted and in
effect in any jurisdiction where property of the Company or its Subsidiaries is
or may be located.

      SECTION 1.14. LIABILITY SOLELY CORPORATE.

      No recourse shall be had for the payment of the principal of (or premium,
if any) or the interest on any Debt Securities or Coupons, or any part thereof,
or of the indebtedness represented thereby, or upon any obligation, covenant or
agreement of this Indenture, against any incorporator, or against any
shareholder, officer or director, as such, past, present or future, of the
Company (or any incorporator, shareholder, officer or director of any
predecessor or successor corporation), either directly or through the Company
(or any such predecessor or successor corporation), whether by virtue of any
constitution, statute or rule of law, or by the enforcement of any assessment or
penalty or otherwise; it being expressly agreed and understood that this
Indenture and all the Debt Securities and Coupons are solely corporate
obligations, and that no personal liability whatsoever shall attach to, or be
incurred by, any such incorporator, shareholder, officer or director, past,
present or future, of the Company (or any incorporator, shareholder, officer or
director of any such predecessor or successor corporation), either directly or
indirectly through the Company or any such predecessor or successor corporation,
because of the indebtedness hereby authorized or under or by reason of any of
the obligations, covenants, promises or agreements contained in this Indenture
or in any of the Debt Securities or Coupons or to be implied herefrom or
therefrom; and that any such personal liability is hereby expressly waived and
released as a condition of, and as part of the consideration for, the execution
of this Indenture and the issue of Debt Securities; provided, however, that
nothing herein or in the Debt Securities or Coupons contained shall be taken to
prevent recourse to and the enforcement of the liability, if any, of any
shareholder or subscriber to capital stock upon or in respect of the shares of
capital stock not fully paid.

                                  ARTICLE II.

variations as are required or permitted by this Indenture, and may have such

      The definitive Debt Securities and Coupons, if any, of each series shall

Note"), such Global Note may provide that it shall represent the aggregate
amount of Outstanding Debt Securities from time to time endorsed thereon and may
also provide 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 Note to reflect the amount, or any increase or decrease
in the amount, or changes in the rights of Holders of Outstanding Debt
Securities represented thereby shall be made by the Trustee and in such manner
as shall be specified in such Global Note. Any instructions by the Company with
respect to a Global Note, after its initial issuance, shall be in writing but
need not comply with Section 1.2 and need not be accompanied by an Opinion of
Counsel.

      Global Notes may be issued in either registered or bearer form and in
either temporary or permanent form. Permanent Global Notes will be issued in

hold such offices prior to the authentication and delivery of such Debt
Securities and Coupons or did not hold such offices at the date of such Debt
Securities and Coupons.

      At any time and from time to time after the execution and delivery of this
Indenture, the Company may deliver Debt Securities, with appropriate Coupons, if
any, of any series, executed by the Company, to the Trustee for authentication,
together with a Company Order for the authentication and delivery of such Debt
Securities and Coupons and the Trustee in accordance with the Company Order
shall authenticate and deliver such Debt Securities and Coupons; provided,
however, that, in connection with its sale during the "restricted period" (as
defined in Section 1.163-5(c)(2)(i)(D)(7) of the United States Treasury
Regulations), no Bearer Security shall be mailed or otherwise delivered to any
location in the United States; and provided, further, that a Bearer Security
(other than a temporary Global Note in bearer form) may be delivered outside the
United States in connection with its original issuance only if the Person
entitled to receive such Bearer Security shall have furnished to the Euro-clear
operator or to CEDEL a certificate substantially in the form set forth in
Exhibit A to this Indenture. If all the Debt Securities of any one series are
not to be issued at one time and if a Board Resolution or supplemental indenture
relating to such series shall so permit, such Company Order may set forth
procedures acceptable to the Trustee for the issuance of such Debt Securities
such as interest rate, Stated Maturity, date of issuance and date from which
interest, if any, shall accrue. If any Debt Security shall be represented by a
Permanent Global Note, then, for purposes of this Section and Section 3.4, the
notation of a beneficial owner's interest therein upon original issuance of such
Debt Security or upon exchange of a portion of a temporary Global Note shall be
deemed to be delivery in connection with the original issuance of such
beneficial owner's interest in such Permanent Global Note. Except as permitted
by Section 3.6 or 3.7, the Trustee shall not authenticate and deliver any Bearer
Security unless all Coupons for interest then matured have been detached and
canceled.

      The Trustee shall be entitled to receive, and (subject to Section 6.1)
shall be fully protected in relying upon, prior to the authentication and
delivery of the Debt Securities and Coupons of such series, (i) the supplemental
indenture or the Board Resolution by or pursuant to which the form and terms of
such Debt Securities and Coupons have been approved and (ii) an Opinion of
Counsel substantially to the effect that:

            (1) the authentication order furnished by the Company to the Trustee
      in connection with the authentication and delivery of such Debt Securities
      and Coupons conforms to the requirements of this Indenture and constitutes
      sufficient authority hereunder for the Trustee to authenticate and deliver
      such Debt Securities and Coupons;

            (2) the forms and terms of such Debt Securities and Coupons are
      consistent with the provisions of this Indenture;

            (3) in the event that the forms or terms of such Debt Securities and
      Coupons have been established in a supplemental indenture, the execution
      and delivery of such supplemental indenture has been duly authorized by
      all necessary corporate action of the Company, such supplemental indenture
      has been duly executed and delivered by the Company and, assuming due
      authorization, execution and delivery by the Trustee, is a valid and
      binding obligation enforceable against the Company in accordance with its
      terms, subject to applicable bankruptcy, insolvency and similar laws
      affecting creditors' rights

                                       23
<PAGE>

      generally and subject, as to enforceability, to general principles of
      equity (regardless of whether enforcement is sought in a proceeding in
      equity or at law);

            (4) the execution and delivery of such Debt Securities and Coupons
      have been duly authorized by all necessary corporate action of the Company
      and such Debt Securities and Coupons have been duly executed by the
      Company and, assuming due authentication by the Trustee and delivery by
      the Company, are valid and binding obligations enforceable against the
      Company in accordance with their terms, entitled to the benefit of the
      Indenture, subject to applicable bankruptcy, insolvency and similar laws
      affecting creditors' rights generally and subject, as to enforceability,
      to general principles of equity (regardless of whether enforcement is
      sought in a proceeding in equity or at law) and subject to such other
      exceptions as counsel shall request and as to which the Trustee shall not
      reasonably object; and

            (5) the amount of Debt Securities Outstanding of such series,
      together with the amount of such Debt Securities, does not exceed any
      limit established under the terms of this Indenture on the amount of Debt
      Securities of such series that may be authenticated and delivered.

      The Trustee shall not be required to authenticate such Debt Securities and
Coupons if the issuance of such Debt Securities and Coupons pursuant to this
Indenture will affect the Trustee's own rights, duties or immunities under the
Debt Securities and this Indenture in a manner which is not reasonably
acceptable to the Trustee.

      Each Registered Security shall be dated the date of its authentication.
Each Bearer Security (including any temporary or permanent or other definitive
Bearer Security in global form) shall be dated as of the date of original
issuance of the first Debt Security of such series to be issued, except as
otherwise provided pursuant to Section 3.1 with respect to the Bearer Securities
of any series.

      No Debt Security 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 one of the forms
provided for herein duly executed by the Trustee or by an Authenticating Agent,
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 and is entitled to the benefits of this Indenture.
Notwithstanding the foregoing, if any Debt Security 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 3.8 together with a written statement (which need not
comply with Section 1.2) stating that such Debt Security 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.

      SECTION 3.4. TEMPORARY DEBT SECURITIES; EXCHANGE OF TEMPORARY GLOBAL NOTES
FOR DEFINITIVE BEARER SECURITIES; GLOBAL NOTES REPRESENTING REGISTERED
SECURITIES.

      (a) Pending the preparation of definitive Registered Securities of any
series, the Company may execute, and upon Company Order the Trustee shall
authenticate and deliver, temporary Registered Securities which are printed,
lithographed, typewritten, mimeographed or otherwise produced, in any authorized
denomination for Registered Securities of such series, substantially of the
tenor of the definitive Registered Securities in lieu of which they are issued
and with such appropriate insertions, omissions, substitutions and other
variations as the officers executing such Registered Securities may determine,
as conclusively evidenced by their execution of such Registered Securities.
Every such temporary Registered Security shall be executed by the Company and
shall be authenticated and delivered by the Trustee upon the same conditions and
in substantially the same manner, and with the same effect, as the definitive
Registered Securities in lieu of which they are issued. In the case of any
series issuable as Bearer Securities, such temporary Debt Securities may be in
global form, representing such of the Outstanding Debt Securities of such series
as shall be specified therein.

      Except in the case of temporary Debt Securities in global form (which
shall be exchanged in accordance with the provisions of the following
paragraphs), 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 temporary Debt Securities of such series shall be exchangeable for
definitive Debt Securities of such series, of a like Stated Maturity and with
like terms and provisions, upon surrender of the temporary Debt Securities of
such series at the office or agency of the Company in a Place of Payment for
such series, without charge to the Holder, except as provided in Section 3.5 in
connection with a transfer. Upon surrender for cancellation of any one or more
temporary Debt Securities of any series (accompanied by any unmatured Coupons),
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 authorized denominations and of a like Stated Maturity and like
terms and provisions; provided, however, that no definitive Bearer Security
shall be delivered in exchange for a temporary Registered Security; and
provided, further, that a definitive Bearer Security (including a permanent
Bearer Security in global form) shall be delivered in exchange for a temporary
Bearer Security only in compliance with the conditions set forth in Section 3.3.
Until so exchanged, the temporary Registered Securities of any series shall in
all respects be entitled to the same benefits under this Indenture as definitive
Registered Securities of such series.

      (b) Unless otherwise specified pursuant to Section 3.1, all Bearer
Securities of a series shall be initially issued in the form of a single
temporary Bearer Security in global form (a "temporary Global Note"). The
Company shall execute, and upon Company Order the Trustee shall authenticate,
any temporary Global Note and any permanent Bearer Security in global form (as
described below, a "Permanent Global Note") upon the same conditions and in
substantially the same manner, and with the same effect, as definitive Bearer
Securities, and the temporary or Permanent Global Note, as the case may be,
shall, unless otherwise specified therein, be delivered by the Trustee to the
London office of a depositary or common depositary (the "Common Depositary"),
for the benefit of the Euro-clear Operator or CEDEL, as the case may be, for
credit to the account of the Company (in the case of sales of Bearer Securities
by the

                                       25
<PAGE>

Company directly to investors) or the managing underwriter (in the case of sales
of Bearer Securities by the Company to underwriters) or such other accounts as
the Company or the managing underwriter, respectively, may direct.

      On or after the date specified in or determined pursuant to the terms of
any temporary Global Note which (subject to any applicable laws and regulations)
shall be at least 40 days after the issue date of a temporary Global Note (the
"Exchange Date"), the Debt Securities represented by such temporary Global Note
may be exchanged for definitive Debt Securities (subject to the second
succeeding paragraph) or Debt Securities to be represented thereafter by one or
more Permanent Global Notes in definitive form without interest coupons. On or
after the Exchange Date such temporary Global Note shall be surrendered by the
Common Depositary to the Trustee, as the Company's agent for such purpose, at
such address as the Trustee may specify and following such surrender, the
Trustee shall (1) endorse the temporary Global Note to reflect the reduction of
its principal amount by an equal aggregate principal amount of such Debt
Security, (2) endorse the applicable Permanent Global Note, if any, to reflect
the initial amount, or an increase in the amount of Debt Securities represented
thereby, (3) manually authenticate such definitive Debt Securities (including
any Permanent Global Note), (4) deliver such definitive Debt Securities to the
Holder thereof or, if such definitive Debt Security is a Permanent Global Note,
deliver such Permanent Global Note to the Common Depositary to be held outside
the United States for the accounts of the Euro-clear Operator or CEDEL, as the
case may be, for credit to the respective accounts at Euro-clear Operator or
CEDEL, as the case may be, designated by or on behalf of the beneficial owners
of such Debt Securities (or to such other accounts as they may direct) and (5)
redeliver such temporary Global Note to the Common Depositary, unless such
temporary Global Note shall have been canceled in accordance with Section 3.8
hereof; provided, however, that, unless otherwise specified in such temporary
Global Note, upon such presentation by the Common Depositary, such temporary
Global Note shall be accompanied by a certificate dated the Exchange Date or a
subsequent date and signed by the Euro-clear Operator, as to the portion of such
temporary Global Note held for its account then to be exchanged for definitive
Debt Securities (including any Permanent Global Note), and a certificate dated
the Exchange Date or a subsequent date and signed by CEDEL, as to the portion of
such temporary Global Note held for its account then to be exchanged for
definitive Debt Securities (including any Permanent Global Note), each
substantially in the form set forth in Exhibit B to this Indenture. Each
certificate substantially in the form of Exhibit B hereto of the Euro-clear
Operator or CEDEL, as the case may be, shall be based on certificates of the
account holders listed in the records of the Euro-clear Operator or CEDEL, as
the case may be, as being entitled to all or any portion of the applicable
temporary Global Note. An account holder of the Euro-clear Operator or CEDEL, as
the case may be, desiring to effect the exchange of an interest in a temporary
Global Note for an interest in definitive Debt Securities (including any
Permanent Global Note) shall instruct the Euro-clear Operator or CEDEL, as the
case may be, to request such exchange on its behalf and shall deliver to the
Euro-clear Operator or CEDEL, as the case may be, a certificate substantially in
the form of Exhibit A hereto and dated no earlier than 10 days prior to the
Exchange Date. Until so exchanged, temporary Global Notes shall in all respects
be entitled to the same benefits under this Indenture as definitive Debt
Securities (including any Permanent Global Note) of the same series
authenticated and delivered hereunder, except as to payment of interest, if any.

                                       26
<PAGE>

      The delivery to the Trustee by the Euro-clear Operator or CEDEL of any
certificate substantially in the form of Exhibit B hereto may be relied upon by
the Company and the Trustee as conclusive evidence that a corresponding
certificate or certificates has or have been delivered to the Euro-clear
Operator or CEDEL, as the case may be, pursuant to the terms of this Indenture.

      On or prior to the Exchange Date, the Company shall deliver to the Trustee
definitive Debt Securities in an aggregate principal amount equal to the
principal amount of such temporary Global Note, executed by the Company. At any
time, on or after the Exchange Date, upon 30 days' notice to the Trustee by the
Euro-clear Operator or CEDEL, as the case may be, acting at the request of or on
behalf of the beneficial owner, a Debt Security represented by a temporary
Global Note or a Permanent Global Note, as the case may be, may be exchanged, in
whole or from time to time in part, for definitive Debt Securities without
charge and the Trustee shall authenticate and deliver, in exchange for each
portion of such temporary Global Note or such Permanent Global Note, an equal
aggregate principal amount of definitive Debt Securities of the same series of
authorized denominations and of a like Stated Maturity and with like terms and
conditions, as the portion of such temporary Global Note or such Permanent
Global Note to be exchanged, which, unless the Debt Securities of the series are
not issuable both as Bearer Securities and as Registered Securities, as
contemplated by Section 3.1, shall be in the form of Bearer Securities or
Registered Securities, or any combination thereof, as shall be specified by the
beneficial owner thereof; provided, however, that definitive Bearer Securities
shall be delivered in exchange for a portion of the temporary Global Note or the
Permanent Global Note only in compliance with the requirements of the second
preceding paragraph. On or prior to the forty-fifth day following receipt by the
Trustee of such notice with respect to a Debt Security, or, if such day is not a
Business Day, the next succeeding Business Day, the temporary Global Note or the
Permanent Global Note, as the case may be, shall be surrendered by the Common
Depositary to the Trustee, as the Company's agent for such purpose, to be
exchanged, in whole or from time to time in part, for definitive Debt Securities
without charge following such surrender, upon the request of the Euro-clear
Operator or CEDEL, as the case may be, and the Trustee shall (1) endorse the
applicable temporary Global Note or the Permanent Global Note to reflect the
reduction of its principal amount by the aggregate principal amount of such Debt
Security, (2) cause the terms of such Debt Security and Coupons, if any, to be
entered on a definitive Debt Security, (3) manually authenticate such definitive
Debt Security, and (4) if a Bearer Security is to be delivered, deliver such
definitive Debt Security to an address outside the United States to the
Euro-clear Operator or CEDEL, as the case may be, for or on behalf of the
beneficial owner thereof, in exchange for a portion of such temporary Global
Note or the Permanent Global Note.

      Unless otherwise specified in such temporary Global Note or the Permanent
Global Note, any such exchange shall be made free of charge to the beneficial
owners of such temporary Global Note or the Permanent Global Note, 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 the
Euro-clear Operator or CEDEL. Definitive Debt Securities in bearer form to be
delivered in exchange for any portion of a temporary Global Note or the
Permanent Global Note shall be delivered only to an address outside the United
States. Notwithstanding the foregoing, in the event of redemption or
acceleration of all or any part of a temporary Global Note prior to the

                                       27
<PAGE>

Exchange Date, a Permanent Global Note or definitive Bearer Securities, as the
case may be, will not be issuable in respect of such temporary Global Note or
such portion thereof, and payment thereon will instead be made as provided in
such temporary Global Note.

      Until exchanged in full as hereinabove provided, any temporary Global Note
or the Permanent Global Note shall in all respects be entitled to the same
benefits under this Indenture as definitive Debt Securities of the same series
and tenor authenticated and delivered hereunder, except that, unless otherwise
specified as contemplated by Section 3.1, interest payable on such temporary
Global Note on an Interest Payment Date for Debt Securities of such series
occurring prior to the applicable Exchange Date shall be payable to the
Euro-clear Operator or CEDEL on such Interest Payment Date upon delivery by the
Euro-clear Operator or CEDEL to the Trustee of a certificate or certificates
substantially in the form set forth in Exhibit B to this Indenture, 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 Note on such Interest Payment Date and who have each delivered
to the Euro-clear Operator or CEDEL, as the case may be, a certificate
substantially in the form set forth in Exhibit A to this Indenture.

      Any definitive Bearer Security authenticated and delivered by the Trustee
in exchange for a portion of a temporary Global Note or the Permanent Global
Note shall not bear a coupon for any interest which shall theretofore have been
duly paid by the Trustee to the Euro-clear Operator or CEDEL, or by the Company
to the Trustee in accordance with the provisions of this Section 3.4.

      With respect to Exhibits A and B to this Indenture, the Company may, in
its discretion and if required or desirable under applicable law or as set forth
in any Board Resolution or Supplemental Indenture with respect to any Series of
Debt Securities, substitute one or more other forms of such exhibits for such
exhibits, eliminate the requirement that any or all certificates be provided, or
change the time that any certificate may be required, provided that such
substitute form or forms or notice of elimination or change of such
certification requirement have theretofore been delivered to the Trustee with a
Company Request and such form or forms, elimination or change is reasonably
acceptable to the Trustee.

      (c) If the Company shall establish pursuant to Section 3.1 that the
Registered Securities of a series are to be issued in whole or in part in the
form of one or more Global Notes, then the Company shall execute and the Trustee
shall, in accordance with Section 3.3 and the Company Order with respect to such
series, authenticate and deliver one or more Global Notes in temporary or
Permanent form that (i) shall represent and shall be denominated in an amount
equal to the aggregate principal amount of the Outstanding Debt Securities of
such series to be represented by one or more Global Notes, (ii) shall be
registered in the name of the U.S. Depositary for such Global Note or Notes or
the nominee of such depositary, and (iii) shall bear a legend substantially to
the following effect: "This Debt Security may not be transferred except as a
whole by the Depositary to a nominee of the Depositary or by a nominee of the
Depositary to the Depositary or another nominee of the Depositary or by the
Depositary or any such nominee to a successor Depositary or a nominee of such
successor Depositary, unless and until this Debt Security is exchanged in whole
or in part for Debt Securities in definitive form."

                                       28
<PAGE>

      Notwithstanding any other provision of this Section or Section 3.5, unless
and until it is exchanged in whole or in part for Registered Securities in
definitive form, a Global Note representing all or a portion of the Registered
Securities of a series may not be transferred except as a whole by the U.S.
Depositary for such series to a nominee of such depositary or by a nominee of
such depositary to such depositary or another nominee of such depositary or by
such depositary or any such nominee to a successor U.S. Depositary for such
series or a nominee of such successor depositary.

      If at any time the U.S. Depositary for the Debt Securities of a series
notifies the Company that it is unwilling or unable to continue as U.S.
Depositary for the Debt Securities of such series or if at any time the U.S.
Depositary for Debt Securities of a series shall no longer be a clearing agency
registered and in good standing under the Securities Exchange Act of 1934, as
amended, or other applicable statute or regulation, the Company shall appoint a
successor U.S. Depositary with respect to the Debt Securities of such series. If
a successor U.S. 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 condition, 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,
Registered Securities of such series in definitive form in an aggregate
principal amount equal to the principal amount of the Global Note or Notes
representing such series in exchange for such Global Note or Notes.

      The Company may at any time and in its sole discretion determine that the
Registered Securities of any series issued in the form of one or more Global
Notes shall no longer be represented by such Global Note or Notes. 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, Registered Securities of such series in
definitive form and in an aggregate principal amount equal to the principal
amount of the Global Note or Notes representing such series in exchange for such
Global Note or Notes.

      If the Registered Securities of any series shall have been issued in the
form of one or more Global Notes and if an Event of Default with respect to the
Debt Securities of such series shall have occurred and be continuing, the
Company will promptly 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, Registered Securities of such series in
definitive form and in an aggregate principal amount equal to the principal
amount of the Global Note or Notes representing such series in exchange for such
Global Note or Notes.

      If specified by the Company pursuant to Section 3.1 with respect to
Registered Securities of a series, the U.S. Depositary for such series of
Registered Securities may surrender a Global Note for such series of Debt
Securities in exchange in whole or in part for Registered Securities of such
series 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:

            (i) to each Person specified by the U.S. Depositary a new Registered
      Security or Securities of the same series, of any authorized denomination
      as

                                       29
<PAGE>

      requested by such Person in an aggregate principal amount equal to and in
      exchange for such Person's beneficial interest in the Global Note; and

            (ii) to the U.S. Depositary a new Global Note in a denomination
      equal to the difference, if any, between the principal amount of the
      surrendered Global Note and the aggregate principal amount of Registered
      Securities delivered to Holders thereof.

      Upon the exchange of a Global Note for Registered Securities in definitive
form, such Global Note shall be canceled by the Trustee. Debt Securities issued
in exchange for a Global Note pursuant to this subsection (c) shall be
registered in such names and in such authorized denominations as the U.S.
Depositary for such Global Note, pursuant to instructions from its direct or
indirect participants or otherwise, shall instruct the Trustee. The Trustee
shall deliver such Debt Securities to the Persons in whose names such Debt
Securities are so registered.

      SECTION 3.5. REGISTRATION, TRANSFER AND EXCHANGE.

      (a) The Company shall cause to be kept at the Corporate Trust Office of
the Trustee a register (the registers maintained in such office and in any other
office or agency of the Company in a Place of Payment being herein sometimes
collectively 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 and exchanges of
Registered Securities. Such Security Register shall be in written form in the
English language or in any other form capable of being accurately and completely
converted into such form within a reasonable time. The Trustee is hereby
appointed "Security Registrar" for the purpose of registering Registered
Securities and registering transfers and exchanges of Registered Securities as
herein provided; provided, however, that the Company may appoint co-Security
Registrars or the terms of any series of Debt Securities may provide otherwise.

      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, one or more new Registered Securities of
the same series of like aggregate principal amount of such denominations as are
authorized for Registered Securities of such series and of a like Stated
Maturity and with like terms and conditions.

      Except as otherwise provided in Section 3.4 and this Section 3.5, at the
option of the Holder, Registered Securities of any series may be exchanged for
other Registered Securities of the same series of like aggregate principal
amount and of a like Stated Maturity and with like terms and conditions, upon
surrender of the Registered Securities to be exchanged at such office or agency.
Whenever any Registered Securities are surrendered for exchange, the Company
shall execute, and the Trustee shall authenticate and deliver, the Registered
Securities which the Holder making the exchange is entitled to receive.

      (b) If and to the extent specified pursuant to Section 3.1, the provisions
of this Section 3.5(b) shall be applicable to Debt Securities of any series
which are Bearer Securities. At the option of the Holder thereof, to the extent
permitted by law, any Bearer Security of any

                                       30
<PAGE>

series which by its terms is registrable as to principal and interest may be
exchanged for a Registered Security of such series of like aggregate principal
amount and of a like Stated Maturity and with like terms and conditions upon
surrender of such Bearer Security at the Corporate Trust Office or at any other
office or agency of the Company designated pursuant to Section 3.1 for the
purpose of making any such exchanges. Any Coupon Security surrendered for
exchange shall be surrendered with all unmatured Coupons and any matured Coupons
in default attached thereto. 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 in an amount equal to the face
amount of such missing Coupon or Coupons, or the surrender of such missing
Coupon or Coupons may be waived by the Company and the Trustee if there is
furnished to them such security or indemnity as they may require to save each of
them and any Paying Agent harmless. If thereafter the Holder of such Bearer
Security shall surrender to any Paying Agent any such missing Coupon in respect
of which such a payment shall have been made, such Holder shall be entitled to
receive the amount of such payment; provided, however, that except as otherwise
provided in Section 12.3, 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 of a like Stated Maturity and
with like terms and conditions after the close of business at such office or
agency on (i) any Regular Record Date and before the opening of business at such
office or agency on the relevant Interest Payment Date, or (ii) any Special
Record Date and before the opening of business at such office or agency on the
related proposed date for payment of Defaulted Interest, such Bearer Security
shall be surrendered without the Coupon relating to such Interest Payment Date
or proposed date for payment, as the case may be (or, if such Coupon is so
surrendered with such Bearer Security, such Coupon shall be returned to the
Person so surrendering the Bearer Security), and interest or Defaulted Interest,
as the case may be, will not be payable on such Interest Payment Date or
proposed date for payment, as the case may be, in respect of the Registered
Security issued in exchange for such Bearer Security, but will be payable only
to the Holder of such Coupon when due in accordance with the provisions of this
Indenture. The Company shall execute, and the Trustee shall authenticate and
deliver, the Registered Security or Securities which the Holder making the
exchange is entitled to receive.

      Notwithstanding the foregoing, the exchange of Bearer Securities for
Registered Securities will be subject to the provisions of United States income
tax laws and regulations applicable to Debt Securities in effect at the time of
such exchange.

      (c) Except as otherwise specified pursuant to Section 3.1, in no event may
Registered Securities, including Registered Securities received in exchange for
Bearer Securities, be exchanged for Bearer Securities.

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

                                       31
<PAGE>

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

      No service charge will be made for any transfer or exchange of Debt
Securities except as provided in Section 3.4(b) or 3.6. 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 registration, transfer or exchange of Debt
Securities, other than those 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 register, transfer or exchange
Debt Securities of any series during a period beginning at the opening of
business 15 days before the day of the transmission of a notice of redemption of
Debt Securities of such series selected for redemption under Section 13.3 and
ending at the close of business on the day of such transmission, or (ii) to
register, transfer or exchange any Debt Security so selected for redemption in
whole or in part, except the unredeemed portion of any Debt Security being
redeemed in part.

      SECTION 3.6. MUTILATED, DESTROYED, LOST AND STOLEN DEBT SECURITIES.

      If (i) any mutilated Debt Security or any mutilated Coupon with the Coupon
Security to which it appertains (and all unmatured Coupons attached thereto) is
surrendered to the Trustee at its Corporate Trust Office, or (ii) the Company
and the Trustee receive evidence to their satisfaction of the destruction, loss
or theft of any Debt Security or any 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 and any Paying Agent harmless, and neither the Company nor the
Trustee receives notice that such Debt Security or Coupon has been acquired by a
bona fide purchaser, then the Company shall execute and upon Company Request the
Trustee shall authenticate and deliver, in exchange for or in lieu of any such
mutilated, destroyed, lost or stolen Debt Security or in exchange for the Coupon
Security to which such mutilated, destroyed, lost or stolen Coupon appertained,
a new Debt Security of the same series of like Stated Maturity and with like
terms and conditions and like principal amount, bearing a number not
contemporaneously Outstanding, and, in the case of a Coupon Security, with such
Coupons attached thereto that neither gain nor loss in interest shall result
from such exchange or substitution.

      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 the amount due on
such Debt Security or Coupon in accordance with its terms; provided, however,
that principal of (and premium, if any) and any interest on Bearer Securities
shall, except as otherwise provided in Section 12.3, be payable only at an
office or agency located outside the United States and, unless otherwise
specified as contemplated by Section 3.1 or except as otherwise provided in this
Section 3.6, any interest on Bearer Securities shall be payable only upon
presentation and surrender of the Coupons appertaining thereto.

      Upon the issuance of any new Debt Security under this Section, the Company
may require the payment of a sum sufficient to cover any tax or other
governmental charge that may

                                       32
<PAGE>

be imposed in respect thereto and any other expenses (including the fees and
expenses of the Trustee) connected therewith.

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

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

      SECTION 3.7. PAYMENT OF INTEREST; INTEREST RIGHTS PRESERVED.

      (a) Unless otherwise specified as contemplated by Section 3.1 with respect
to the Debt Securities of any series, 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 such Registered Security (or one
or more Predecessor Securities) is registered at the close of business on the
Regular Record Date for such interest notwithstanding the cancellation of such
Registered Security upon any transfer or exchange subsequent to the Regular
Record Date. Unless otherwise specified as contemplated by Section 3.1 with
respect to the Debt Securities of any series, payment of interest on Registered
Securities shall be made at the place or places specified pursuant to Section
3.1 or, at the option of the Company, by check mailed to the address of the
Person entitled thereto as such address shall appear in the Security Register
or, if provided pursuant to Section 3.1, by wire transfer to an account
designated by the Registered Holder.

      (b) Interest on any Coupon Security which is payable and is punctually
paid or duly provided for on any Interest Payment Date shall be paid to the
Holder of the Coupon which has matured on such Interest Payment Date upon
surrender of such Coupon on such Interest Payment Date at the Corporate Trust
Office of the Trustee or at such other Place of Payment outside the United
States specified pursuant to Section 3.1.

      Interest on any Bearer Security (other than a Coupon Security) which is
payable and is punctually paid or duly provided for on any Interest Payment Date
shall be paid to the Holder of the Bearer Security upon presentation of such
Bearer Security and notation thereon on such Interest Payment Date at the
Corporate Trust Office of the Trustee or at such other Place of Payment
maintained by the Company outside the United States specified pursuant to
Section 3.1.

      Unless otherwise specified pursuant to Section 3.1, at the direction of
the Holder of any Bearer Security or Coupon payable in Dollars, payment on such
Bearer Security or Coupon will be made by check drawn on a bank in The City of
[____] or, if agreeable to the Trustee, by wire transfer to a Dollar account
maintained by such Holder outside the United States. If such payment at the
offices of all Paying Agents outside the United States becomes illegal or is
effectively precluded because of the imposition of exchange controls or similar
restrictions on the full payment or receipt of such amounts in Dollars, the
Company will appoint an office or

                                       33
<PAGE>

agent in the United States at which such payment may be made. Unless otherwise
specified pursuant to Section 3.1, at the direction of the Holder of any Bearer
Security or Coupon payable in a Foreign Currency, payment on such Bearer
Security or Coupon will be made by a check drawn on a bank outside the United
States or by wire transfer to an appropriate account maintained by such Holder
outside the United States. Except as provided in this paragraph, no payment on
any Bearer Security or Coupon will be made by mail to an address in the United
States or by wire transfer to an account in the United States.

      (c) Any interest on any Debt Security which is payable but is not
punctually paid or duly provided for on any Interest Payment Date (herein called
"Defaulted Interest") shall, if such Debt Security is a Registered Security,
forthwith cease to be payable to the Registered Holder on the relevant Regular
Record Date by virtue of his having been such Registered 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 such Registered Securities (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 such Registered Security and the date of the proposed payment, and
      at the same time the Company shall deposit with the Trustee an amount of
      money in the Currency or Currency unit in which the Debt Securities of
      such series are payable (except as otherwise specified pursuant to
      Sections 3.1 or 3.10) equal to the aggregate amount proposed to be paid in
      respect of such Defaulted Interest or shall make arrangements satisfactory
      to the Trustee for such deposit prior to the date of the proposed payment,
      such money when deposited to be held in trust for the benefit of the
      Persons entitled to such Defaulted Interest as in this clause provided.
      Thereupon the Trustee shall fix a Special Record Date for the payment of
      such Defaulted Interest which date shall be not more than 15 days and not
      less than 10 days prior to the date of the proposed payment and not less
      than 10 days after the receipt by the Trustee of the notice of the
      proposed payment. The Trustee shall promptly notify the Company of such
      Special Record Date and, in the name and at the expense of the Company,
      shall cause notice of the proposed payment of such Defaulted Interest and
      the Special Record Date therefor to be mailed, first-class postage
      prepaid, to the Holders of such Registered Securities at their addresses
      as they appear 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 such Registered Securities (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).

            (2) The Company may make payment of any Defaulted Interest on
      Registered Securities in any other lawful manner not inconsistent with the

                                       34
<PAGE>

      requirements of any securities exchange on which such 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.

      (d) Any Defaulted Interest payable in respect of Bearer Securities of any
series shall be payable pursuant to such procedures as may be satisfactory to
the Trustee in such manner that there is no discrimination between the Holders
of Registered Securities (if any) and Bearer Securities of such series, and
notice of the payment date therefor shall be given by the Trustee, in the name
and at the expense of the Company, in the manner provided in Section 1.5 not
more than 25 days and not less than 20 days prior to the date of the proposed
payment.

      (e) Subject to the foregoing provisions of this Section, each Debt
Security delivered under this Indenture upon 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.

      SECTION 3.8. CANCELLATION.

      Unless otherwise specified pursuant to Section 3.1 for Debt Securities of
any series, all Debt Securities surrendered for payment, redemption, transfer,
exchange or credit against any sinking fund and all Coupons surrendered for
payment or exchange shall, if surrendered to any Person other than the Trustee,
be delivered to the Trustee. All Registered Securities and matured Coupons so
delivered shall be promptly canceled by the Trustee. All Bearer Securities and
unmatured Coupons so delivered shall be held by the Trustee and, upon
instruction by the Company Order, shall be canceled or held for reissuance.
Bearer Securities and unmatured Coupons held for reissuance may be reissued only
in exchange for Bearer Securities of the same series and of like Stated Maturity
and with like terms and conditions pursuant to Section 3.5 or in replacement of
mutilated, lost, stolen or destroyed Bearer Securities of the same series and of
like Stated Maturity and with like terms and conditions or the related Coupons
pursuant to Section 3.6. All Bearer Securities and unmatured Coupons held by the
Trustee pending such cancellation or reissuance shall be deemed to be delivered
for cancellation for all purposes of this Indenture and the Securities. The
Company may at any time deliver to the Trustee for cancellation any Debt
Securities or Coupons previously authenticated and delivered hereunder which the
Company may have acquired in any manner whatsoever, and may deliver to the
Trustee (or to any other Person for delivery to the Trustee) for cancellation
any Debt Securities previously authenticated hereunder which the Company has not
issued, and all Debt Securities or Coupons so delivered shall be promptly
canceled by the Trustee. No Debt Securities or Coupons shall be authenticated in
lieu of or in exchange for any Debt Securities or Coupons canceled as provided
in this Section, except as expressly permitted by this Indenture. All canceled
Debt Securities and Coupons held by the Trustee shall be delivered to the
Company upon Company Request. The acquisition of any Debt Securities or Coupons
by the Company shall not operate as a redemption or satisfaction of the
indebtedness represented thereby unless and until such Debt Securities or
Coupons are surrendered to the Trustee for cancellation. In the case of any
temporary Global Note which shall be destroyed if the entire aggregate principal
amount of the Debt Securities represented thereby has been exchanged, the
certificate of destruction shall state that all certificates required pursuant
to Section 3.4 hereof and substantially in the form of

                                       35
<PAGE>

Exhibit B hereto, to be given by the Euro-clear Operator or CEDEL, have been
duly presented to the Trustee by the Euro-clear Operator or CEDEL, as the case
may be. Permanent Global Notes shall not be destroyed until exchanged in full
for definitive Debt Securities or until payment thereon is made in full.

      SECTION 3.9. COMPUTATION OF INTEREST.

      Except as otherwise specified pursuant to Section 3.1 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 3.10. CURRENCY OF PAYMENTS IN RESPECT OF DEBT SECURITIES.

      (a) Except as otherwise specified pursuant to Section 3.1 for Bearer
Securities of any series, payment of the principal of (and premium, if any) and
interest on Bearer Securities of such series denominated in any Currency will be
made in such Currency.

      (b) With respect to Registered Securities of any series not permitting the
election provided for in paragraph (c) below or the Holders of which have not
made the election provided for in paragraph (c) below, except as provided in
paragraph (e) below, payment of the principal of (and premium, if any) and any
interest on any Registered Security of such series will be made in the Currency
in which such Registered Security is payable.

      (c) It may be provided pursuant to Section 3.1 with respect to the
Registered Securities of any series that Holders shall have the option, subject
to paragraphs (e) and (f) below (and provided that in no instance may such
election be made after a defeasance pursuant to Article XV or during the
continuance of an Event of Default), to receive payments of principal of (and
premium, if any) and any interest on such Registered Securities in any of the
Currencies which may be designated for such election in the applicable
supplemental indenture by delivering to the Trustee a written election, to be in
form and substance satisfactory to the Trustee, not later than the close of
business on the Election Date immediately preceding the applicable payment date.
If a Holder so elects to receive such payments in any such Currency, such
election will remain in effect for such Holder or any transferee of such Holder
until changed by such Holder or such transferee by written notice to the Trustee
(but any such change must be made not later than the close of business on the
Election Date immediately preceding the next payment date to be effective for
the payment to be made on such payment date and no such change or election may
be made with respect to payments to be made on any Registered Security of such
series with respect to which an Event of Default has occurred or notice of
redemption has been given by the Company pursuant to Article XIII). Any Holder
of any such Registered Security who shall not have delivered any such election
to the Trustee by the close of business on the applicable Election Date will be
paid the amount due on the applicable payment date in the relevant Currency as
provided in paragraph (b) of this Section 3.10.

      (d) If the election referred to in paragraph (c) above has been provided
for pursuant to Section 3.1, then not later than the fourth Business Day after
the Election Date for each payment date, the Trustee will deliver to the Company
a written notice specifying, in the Currency in which each series of the
Registered Securities is payable, the respective aggregate amounts of

                                       36
<PAGE>

principal of (and premium, if any) and any interest on the Registered Securities
to be paid on such payment date, specifying the amounts so payable in respect of
the Registered Securities as to which the Holders of Registered Securities
denominated in any Currency shall have elected to be paid in another Currency as
provided in paragraph (c) above. If the election referred to in paragraph (c)
above has been provided for pursuant to Section 3.1 and if at least one Holder
has made such election, then, on the second Business Day preceding each payment
date, the Company will deliver to the Trustee an Exchange Rate Officer's
Certificate in respect of the Currency payments to be made on such payment date.
The Currency amount receivable by Holders of Registered Securities who have
elected payment in a Currency as provided in paragraph (c) above shall be
determined by the Company on the basis of the applicable Market Exchange Rate in
effect on the third Business Day (the "Valuation Date") immediately preceding
each payment date.

      (e) If a Conversion Event occurs with respect to a Foreign Currency, the
ECU or any other Currency unit in which any of the Debt Securities are
denominated or payable other than pursuant to an election provided for pursuant
to paragraph (c) above, then with respect to each date for the payment of
principal of (and premium, if any) and any interest on the applicable Debt
Securities denominated or payable in such Foreign Currency, the ECU or such
other Currency unit occurring after the last date on which such Foreign
Currency, the ECU or such other Currency unit was used (the "Conversion Date"),
the Dollar shall be the Currency of payment for use on each such payment date.
The Dollar amount to be paid by the Company to the Trustee and by the Trustee or
any Paying Agent to the Holders of such Debt Securities with respect to such
payment date shall be the Dollar Equivalent of the Foreign Currency or, in the
case of a Currency unit, the Dollar Equivalent of the Currency Unit, in each
case as determined by the Currency Determination Agent, if any, or, if there
shall not be a Currency Determination Agent, then by the Trustee, in the manner
provided in paragraph (g) or (h) below.

      (f) If the Holder of a Registered Security denominated in any Currency
shall have elected to be paid in another Currency as provided in paragraph (c)
above, and a Conversion Event occurs with respect to such elected Currency, such
Holder shall receive payment in the Currency in which payment would have been
made in the absence of such election. If a Conversion Event occurs with respect
to the Currency in which payment would have been made in the absence of such
election, such Holder shall receive payment in Dollars as provided in paragraph
(e) of this Section 3.10.

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

      (h) The "Dollar Equivalent of the Currency Unit" shall be determined by
the Currency Determination Agent, and subject to the provisions of paragraph (i)
below, shall be the sum of each amount obtained by converting the Specified
Amount of each Component Currency into Dollars at the Market Exchange Rate for
such Component Currency on the Valuation Date with respect to each payment.

                                       37
<PAGE>

      (i) For purposes of this Section 3.10 the following terms shall have the
following meanings:

            A "Component Currency" shall mean any Currency which, on the
      Conversion Date, was a component Currency of the relevant Currency unit,
      including, but not limited to, the ECU.

            A "Specified Amount" of a Component Currency shall mean the number
      of units of such Component Currency or fractions thereof which were
      represented in the relevant Currency unit, including, but not limited to,
      the ECU, on the Conversion Date. If after the Conversion Date the official
      unit of any Component Currency is altered by way of combination or
      subdivision, the Specified Amount of such Component Currency shall be
      divided or multiplied in the same proportion. If after the Conversion Date
      two or more Component Currencies are consolidated into a single Currency,
      the respective Specified Amounts of such Component Currencies shall be
      replaced by an amount in such single Currency equal to the sum of the
      respective Specified Amounts of such consolidated Component Currencies
      expressed in such single Currency, and such amount shall thereafter be a
      Specified Amount and such single Currency shall thereafter be a Component
      Currency. If after the Conversion Date any Component Currency shall be
      divided into two or more Currencies, the Specified Amount of such
      Component Currency shall be replaced by amounts of such two or more
      Currencies with appropriate Dollar equivalents at the Market Exchange Rate
      on the date of such replacement equal to the Dollar equivalent of the
      Specified Amount of such former Component Currency at the Market Exchange
      Rate on such date, and such amounts shall thereafter be Specified Amounts
      and such Currencies shall thereafter be Component Currencies. If after the
      Conversion Date of the relevant Currency unit, including but not limited
      to, the ECU, a Conversion Event (other than any event referred to above in
      this definition of "Specified Amount") occurs with respect to any
      Component Currency of such Currency unit, the Specified Amount of such
      Component Currency shall, for purposes of calculating the Dollar
      Equivalent of the Currency Unit, be converted into Dollars at the Market
      Exchange Rate in effect on the Conversion Date of such Component Currency.

            "Election Date" shall mean the earlier of (i) the seventh Business
      Day immediately preceding any payment date or (ii) the record date with
      respect to any payment date, and with respect to the Maturity shall mean
      the record date (if within 16 or fewer days prior to the Maturity)
      immediately preceding the Maturity, and with respect to any series of Debt
      Securities whose record date immediately preceding the Maturity is more
      than 16 days prior to the Maturity or any series of Debt Securities for
      which no record dates are provided with respect to interest payments,
      shall mean the date which is 16 days prior to the Maturity.

      (j) All decisions and determinations of the Trustee or the Currency
Determination Agent, if any, regarding the Dollar Equivalent of the Foreign
Currency, the Dollar Equivalent of the Currency Unit and the Market Exchange
Rate shall be in its sole discretion and shall, in the

                                       38
<PAGE>

absence of manifest error, be conclusive for all purposes and irrevocably
binding upon the Company and all Holders of the Debt Securities denominated or
payable in the relevant Currency. In the event of a Conversion Event with
respect to a Foreign Currency, the Company, after learning thereof, will
immediately give written notice thereof to the Trustee (and the Trustee will
promptly thereafter give notice in the manner provided in Section 1.5 to the
Holders) specifying the Conversion Date. In the event of a Conversion Event with
respect to the ECU or any other Currency unit in which Debt Securities are
denominated or payable, the Company, after learning thereof, will immediately
give notice thereof to the Trustee (and the Trustee will promptly thereafter
give written notice in the manner provided in Section 1.5 to the Holders)
specifying the Conversion Date and the Specified Amount of each Component
Currency on the Conversion Date. In the event of any subsequent change in any
Component Currency as set forth in the definition of Specified Amount above, the
Company, after learning thereof, will similarly give written notice to the
Trustee. The Trustee shall be fully justified and protected in relying and
acting upon information received by it from the Company and the Currency
Determination Agent, if any, and shall not otherwise have any duty or obligation
to determine such information independently.

      (k) For purposes of any provision of the Indenture where the Holders of
Outstanding Debt Securities may perform an Act which requires that a specified
percentage of the Outstanding Debt Securities of all series perform such Act and
for purposes of any decision or determination by the Trustee of amounts due and
unpaid for the principal (and premium, if any) and interest on the Debt
Securities of all series in respect of which moneys are to be disbursed ratably,
the principal of (and premium, if any) and interest on the Outstanding Debt
Securities denominated in a Foreign Currency will be the amount in Dollars based
upon the Market Exchange Rate for Debt Securities of such series, as of the date
for determining whether the Holders entitled to perform such Act have performed
it, or as of the date of such decision or determination by the Trustee, as the
case may be.

      (l) The Company hereby appoints itself as the initial Currency
Determination Agent and the Company shall be entitled to remove such agent at
any time; provided, however, that such removal shall not be effective and the
agent may not resign until a successor has been appointed by the Company and the
successor has accepted such appointment. The Trustee is under no duty or
obligation to serve in the capacity of Currency Determination Agent.

      SECTION 3.11. JUDGMENTS.

      If for the purpose of obtaining a judgment in any court with respect to
any obligation of the Company hereunder or under any Debt Security, it shall
become necessary to convert into any other Currency any amount in the Currency
due hereunder or under such Debt Security, then such conversion shall be made at
the Market Exchange Rate as in effect on the date the Company shall make payment
to any Person in satisfaction of such judgment. If pursuant to any such
judgment, conversion shall be made on a date other than the date payment is made
and there shall occur a change between such Market Exchange Rate and the Market
Exchange Rate as in effect on the date of payment, the Company agrees to pay
such additional amounts (if any) as may be necessary to ensure that the amount
paid is equal to the amount in such other Currency which, when converted at the
Market Exchange Rate as in effect on the date of payment or distribution, is the
amount then due hereunder or under such Debt Security. Any amount due

                                       39
<PAGE>

from the Company under this Section 3.11 shall be due as a separate debt and is
not to be affected by or merged into any judgment being obtained for any other
sums due hereunder or in respect of any Debt Security. In no event, however,
shall the Company be required to pay more in the Currency or Currency unit due
hereunder or under such Debt Security at the Market Exchange Rate as in effect
when payment is made than the amount of Currency stated to be due hereunder or
under such Debt Security so that in any event the Company's obligations
hereunder or under such Debt Security will be effectively maintained as
obligations in such Currency, and the Company shall be entitled to withhold (or
be reimbursed for, as the case may be) any excess of the amount actually
realized upon any such conversion over the amount due and payable on the date of
payment or distribution.

      SECTION 3.12. EXCHANGE UPON DEFAULT.

      If default is made in the payments referred to in Section 12.1, the
Company hereby undertakes that upon presentation and surrender of a Permanent
Global Note to the Trustee (or to any other Person or at any other address as
the Company may designate in writing), on any Business Day on or after the
maturity date thereof the Company will issue and the Trustee will authenticate
and deliver to the bearer of such Permanent Global Note duly executed and
authenticated definitive Debt Securities with the same issue date and maturity
date as set out in such Permanent Global Note.

                                   ARTICLE IV.

                           SATISFACTION AND DISCHARGE

      SECTION 4.1. SATISFACTION AND DISCHARGE OF INDENTURE.

      This Indenture, with respect to the Debt Securities of any series (if all
series issued under this Indenture are not to be affected), shall, upon Company
Request, cease to be of further effect (except as to any surviving rights of
registration of transfer or exchange of such Debt Securities herein expressly
provided for and rights to receive payments of principal (and premium, if any)
and interest on such Debt Securities) 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 and the Coupons, if any, of such series
      theretofore authenticated and delivered (other than (i) Debt Securities
      and Coupons of such series which have been destroyed, lost or stolen and
      which have been replaced or paid as provided in Section 3.6, (ii) Coupons
      appertaining to Bearer Securities surrendered for exchange for Registered
      Securities and maturing after such exchange, whose surrender is not
      required or has been waived under Section 3.5, (iii) Coupons appertaining
      to Bearer Securities called for redemption and maturing after the relevant
      Redemption Date, whose surrender has been waived as provided in Section
      13.6, and (iv) Debt Securities and Coupons of such series for whose
      payment money has theretofore been deposited in trust or segregated and
      held in trust by the Company and thereafter repaid to the

                                       40
<PAGE>

      Company or discharged from such trust, as provided in Section 12.4) have
      been delivered to the Trustee for cancellation; or

            (B) all Debt Securities and the Coupons, if any, of such series not
      theretofore delivered to the Trustee for cancellation,

                  (i) have become due and payable by reason of the making of a
            notice of redemption or otherwise, or

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

            and the Company, either complies with any other condition or terms
            specified pursuant to Section 3.1, or if not so specified in the
            case of (i), (ii) or (iii) of this subclause (B), has irrevocably
            deposited or caused to be deposited with the Trustee as trust funds
            held in trust solely for the benefit of the Holders, cash in United
            States Dollars, non-callable government securities, or a combination
            thereof, in such amounts as will be (except as otherwise provided
            pursuant to Section 3.1 or 3.10) sufficient without consideration of
            any reinvestment of interest, to pay and discharge the entire
            indebtedness on such Debt Securities not delivered to the Trustee
            for cancellation for principal, premium, if any and accrued interest
            to the date of such deposit (in the case of Debt Securities which
            have become due and payable) or to the Stated Maturity or Redemption
            Date, as the case may be;

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

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

Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Company to the Trustee under Section 6.7, the obligations of
the Trustee to any Authenticating Agent under Section 6.14, the obligations of
the Company under Section 12.1, and, if money shall have been deposited with the
Trustee pursuant to subclause (B) of clause (1) of this Section 4.1, the
obligations of the Trustee under Section 4.2 and the last paragraph of Section
12.4, shall survive. If, after the deposit referred to in Section 4.1 has been
made, (x) the Holder of a Debt Security is entitled to, and does, elect pursuant
to Section 3.10(c), to receive payment in a Currency other than that in which
the deposit pursuant to Section 4.1 was made, or (y) if a Conversion Event
occurs with respect to the Currency in which the deposit was made or elected to
be received by the Holder pursuant to Section 3.10(c), then the indebtedness
represented by such Debt Security shall be fully discharged to the extent that
the deposit made with respect to such Debt Security shall be converted into the
Currency in which such payment is made.

      SECTION 4.2. APPLICATION OF TRUST MONEY.

      Subject to the provisions of the last paragraph of Section 12.4, all money
deposited with the Trustee pursuant to Section 4.1 shall be held in trust and
applied by it, in accordance with the provisions of the Debt Securities and
Coupons, if any, and this Indenture, to the payment, either directly or through
any Paying Agent (including the Company acting as its own Paying Agent) as the
Trustee may determine, to the Persons entitled thereto, of the principal (and
premium, if any) and interest for whose payment such money has been deposited
with the Trustee.

                                   ARTICLE V.

                                    REMEDIES

      SECTION 5.1. EVENTS OF DEFAULT.

      "Event of Default" wherever used herein with respect to Debt Securities of
any series, and unless otherwise provided with respect to Debt Securities of any
series pursuant to Section 3.1, means any one of the following events (whatever

or order of any court or any order, rule or regulation of any administrative or
governmental body):

            (1) default in the payment of any interest upon any Debt Security or

      becomes due and payable, and continuance of such default for a period of

      warranty of the Company in this Indenture (other than a covenant or
      warranty a default in whose performance or whose breach is elsewhere in
      this Section specifically dealt with or which expressly has 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 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 Debt
      Securities of such series, a written notice specifying such default or
      breach and requiring it to be remedied and stating that such notice is a
      "Notice of Default" hereunder; or

            (5) the entry of a decree or order for relief in respect of the
      Company by a court having jurisdiction in the premises in an involuntary
      case under the Federal bankruptcy laws, as now or hereafter constituted,
      or any other applicable

                                       42
<PAGE>

      Federal or State bankruptcy, insolvency or other similar law, or a decree
      or order adjudging the Company a bankrupt or insolvent, or approving as
      properly filed a petition seeking reorganization, arrangement, adjustment
      or composition of or in respect of the Company under any applicable
      Federal or State law, or appointing a receiver, liquidator, assignee,
      custodian, 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 unstayed and in effect for a period of 90 consecutive
      days; or

            (6) the commencement by the Company of a voluntary case under the
      Federal bankruptcy laws, as now or hereafter constituted, or any other
      applicable Federal or State bankruptcy, insolvency or other similar law,
      or the consent by it to the entry of an order for relief in an involuntary
      case under any such law or to the appointment of a receiver, liquidator,
      assignee, custodian, trustee, sequestrator (or other 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 its 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

            (7) any other Event of Default provided with respect to Debt
      Securities of that series pursuant to Section 3.1.

      SECTION 5.2. ACCELERATION OF MATURITY; RESCISSION AND ANNULMENT.

      If an Event of Default (unless otherwise provided with respect to Debt
Securities of any series pursuant to Section 3.1, other than an Event of Default
specified in clauses (5) or (6) of Section 5.1) with respect to Debt Securities
of any series at the time Outstanding occurs and is continuing, then in every
such case, unless the principal of all Debt Securities shall have already become
due and payable, the Trustee or the Holders of not less than 25% in principal
amount of the Outstanding Debt Securities of such series may declare the
principal amount (or, if any Debt Securities of such series are Discount
Securities or indexed securities, such portion of the principal amount of such
Discount Securities as may be specified in the terms of such Discount Securities
or indexed securities) of 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 Holders), and upon any such declaration such principal amount (or
specified amount) plus accrued and unpaid interest (and premium, if payable)
shall become immediately due and payable. Unless otherwise provided with respect
to Debt Securities of any series pursuant to Section 3.1, if an Event of Default
specified in clauses (5) or (6) of Section 5.1 occurs, such an amount shall ipso
facto become and be immediately due and payable without any declaration or other
act on the part of the Trustee or any Holder. Upon payment of such amount in the
Currency in which such Debt Securities are denominated (except as otherwise
provided pursuant to Sections 3.1 or 3.10), 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

                                       43
<PAGE>

obtained by the Trustee as hereinafter in this Article V 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 in the
      Currency in which such Debt Securities are denominated (except as
      otherwise provided pursuant to Section 3.1 or 3.10) sufficient to pay

                  (A)   all overdue installments of interest on all Debt
                        Securities or all overdue payments with respect to any
                        Coupons 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 on each
                        Debt Security of such series or upon overdue payments on
                        any Coupons of such series at the Overdue Rate, 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;
                        provided, however, that all sums payable under this
                        clause (D) shall be paid in Dollars;

            and

            (2) All Events of Default with respect to Debt Securities of such
      series, other than the nonpayment of the principal of Debt Securities of
      such series which has become due solely by such declaration of
      acceleration, have been cured or waived as provided in Section 5.13.

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

      SECTION 5.3. COLLECTION OF INDEBTEDNESS AND SUITS FOR ENFORCEMENT BY
      TRUSTEE.

      The Company covenants that if

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

                                       44
<PAGE>

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

            (3) default is made in the making or satisfaction of any sinking
      fund payment or analogous obligation when the same becomes due pursuant to
      the terms of the Debt Securities of any series, and such default continues
      for a period of 30 days,

the Company will, upon demand of the Trustee, pay to it, for the benefit of the
Holders of such Debt Securities or of such Coupons, the amount then due and
payable on such Debt Securities or matured Coupons, for the principal (and
premium, if any) and interest, if any, 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 Overdue Rate;
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 amount 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 and
Coupons of such series by such appropriate judicial proceedings as the Trustee
shall deem most effectual to protect and enforce any such rights, whether for
the specific enforcement of any covenant or agreement in this Indenture or in
aid of the exercise of any power granted herein, or to enforce any other proper
remedy.

      SECTION 5.4. TRUSTEE MAY FILE PROOFS OF CLAIM.

      In case of 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 and Coupons, if any, of a particular
series or all or substantially all of 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 of acceleration 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 proceeding or otherwise,

            (i) to file and prove a claim for the whole amount of principal (or,
      if the Debt Securities of such series are Discount Securities, such
      portion of the

                                       45
<PAGE>

      principal amount as may be due and payable with respect to such series
      pursuant to a declaration in accordance with Section 5.2) (and premium, if
      any) and interest owing and unpaid in respect of the Debt Securities and
      Coupons of such series 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 of such Debt Securities and Coupons allowed in such judicial
      proceeding, and

            (ii) to collect and receive any moneys or other property payable or
      deliverable on any such claims and to distribute the same; and any
      receiver, assignee, trustee, custodian, liquidator, sequestrator (or other
      similar official) in any such proceeding is hereby authorized by each such
      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 such
      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
      6.7.

      Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Holder any plan of
reorganization, arrangement, adjustment or composition affecting the Debt
Securities and any Coupons of such series 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 5.5. TRUSTEE MAY ENFORCE CLAIMS WITHOUT POSSESSION OF DEBT
SECURITIES.

      All rights of action and claims under this Indenture or the Debt
Securities and the Coupons, if any, of any series may be prosecuted and enforced
by the Trustee without the possession of any of such 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 or Coupons in respect of which such judgment
has been recovered.

      SECTION 5.6. APPLICATION OF MONEY COLLECTED.

      Any money collected by the Trustee pursuant to this Article V 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 Coupons of any
series in respect of which money has been collected 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
      6.7.

            SECOND: To the payment of the amounts then due and unpaid for
      principal of (and premium, if any) and interest on the Debt Securities or
      Coupons

                                       46
<PAGE>

      of such series, 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 or
      Coupons for principal (and premium, if any) and interest, respectively;
      and

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

      SECTION 5.7. LIMITATION ON SUITS.

      No Holder of any Debt Security or Coupon of any series shall have any
right to institute any action or proceeding, judicial or otherwise, at law or in
equity or in bankruptcy or otherwise with respect to this Indenture, or for the
appointment of a receiver, trustee, liquidator, custodian sequestrator (or other
similar official) or for any other remedy hereunder, unless

            (1) such Holder has previously given written notice to the Trustee
      of a continuing Event of Default with respect to 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 of the Holders of Outstanding Debt Securities or Coupons of any other
series, or to obtain or to seek to obtain priority or preference over any other
of such Holders or to enforce any right under this Indenture, except in the
manner herein provided and for the equal and ratable benefit of all of such
Holders. For the protection and enforcement of the provisions of this Section
5.7, each and every Holder of Debt Securities or Coupons of any series and the
Trustee for such series shall be entitled to such relief as can be given at law
or in equity.

      SECTION 5.8. UNCONDITIONAL RIGHT OF HOLDERS TO RECEIVE PRINCIPAL, PREMIUM
AND INTEREST.

      Notwithstanding any other provision in this Indenture, the Holder of any
Debt Security or of any Coupon shall have the right, which is absolute and
unconditional, to receive payment of

                                       47
<PAGE>

the principal of (and premium, if any) and (subject to Section 3.7) interest on
such Debt Security or Coupon on the respective Stated Maturity or Maturities
expressed in such Debt Security or Coupon (or, in the case of redemption, on the
Redemption Date) and to institute suit for the enforcement of any such payment
and interest thereon, and such right shall not be impaired without the consent
of such Holder.

      SECTION 5.9. RESTORATION OF RIGHTS AND REMEDIES.

      If the Trustee or any Holder has instituted any proceeding to enforce any
right or remedy under this Indenture and such proceeding has been discontinued
or abandoned for any reason, or has been determined adversely to the Trustee or
to such Holder, then and in every such case the Company, the Trustee and the
Holders shall, subject to any determination in such proceeding, be restored
severally and respectively to their former positions and rights hereunder, and
thereafter all rights and remedies of the Company, Trustee and the Holders shall
continue as though no such proceeding had been instituted.

      SECTION 5.10. RIGHTS AND REMEDIES CUMULATIVE.

      Except as otherwise expressly provided elsewhere in this Indenture, 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 5.11. DELAY OR OMISSION NOT WAIVER.

      No delay or omission of the Trustee or of any Holder 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 any acquiescence
therein. Every right and remedy given by this Indenture 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 5.12. CONTROL BY HOLDERS.

      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 by this Indenture 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 6.1, 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

                                       48
<PAGE>

      proceeding so directed would be unjustly prejudicial to the Holders of
      Debt Securities of such series not joining in any such direction; and

            (3) the Trustee may take any other action deemed proper by the
      Trustee which is not inconsistent with such direction.

      SECTION 5.13. WAIVER OF PAST DEFAULTS.

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

            (1) in the payment of the principal of (or premium, if any) or
      interest on any Debt Security of such series, or in the payment of any
      sinking fund installment or analogous obligation with respect to the Debt
      Securities of such series; or

            (2) in respect of a covenant or provision hereof which pursuant to
      Article XI cannot be modified or amended without the consent of the Holder
      of each Outstanding Debt Security of such series affected; provided that a
      majority in principal amount of the Outstanding Debt Securities of a given
      series may rescind and annul a declaration of acceleration with respect to
      Debt Securities of such series as provided in Section 5.2.

      Upon any such waiver, such default shall cease to exist, and any Event of
Default arising therefrom shall be deemed to have been cured and not to have
occurred, for every purpose of the Debt Securities of such series under this
Indenture, but no such waiver shall extend to any subsequent or other default or
impair any right consequent thereon.

      SECTION 5.14. UNDERTAKING FOR COSTS.

      All parties to this Indenture agree, and each Holder of any Debt Security
or any 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 other than the Trustee of an undertaking to pay the costs
of such suit, and that such court may in its discretion assess reasonable costs,
including reasonable attorneys' fees, against any party litigant in such suit,
having due regard to the merits and good faith of the claims or defenses made by
such party litigant, but the provisions of this Section shall not apply to any
suit instituted by the Company, to any suit instituted by the Trustee, to any
suit instituted by any Holder or group of Holders holding in the aggregate more
than 10% in principal amount of the Outstanding Debt Securities of any series,
or to any suit instituted by any Holder of a Debt Security or Coupon for the
enforcement of the payment of the principal of (or premium, if any) or interest
on such Debt Security or the payment of any Coupon on or after the respective
Stated Maturity or Maturities expressed in such Debt Security or Coupon (or, in
the case of redemption, on or after the Redemption Date).

      SECTION 5.15. 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 wherever enacted,
now or at any time hereafter in force, which may affect the covenants or the
performance of this Indenture; and the Company (to the extent that it may
lawfully do so) hereby expressly waives all benefit or advantage of any such
law, and covenants that it will not hinder, delay or impede the execution of any
power herein granted to the Trustee, but will suffer and permit the execution of
every such power as though no such law had been enacted.

                                   ARTICLE VI.

                                   THE TRUSTEE

      SECTION 6.1. CERTAIN DUTIES AND RESPONSIBILITIES.

      (a) Except during the continuance of an Event of Default with respect to
the Debt Securities of any series:

            (1) the Trustee undertakes to perform such duties and only such
      duties as are specifically set forth in this Indenture, and no implied
      covenants or obligations shall be read into this Indenture against the
      Trustee; and

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

      (b) In case an Event of Default with respect to Debt Securities of any
series has occurred and is continuing, the Trustee shall, with respect to the
Debt Securities of such series, exercise such of the rights and powers vested in
it by this Indenture, and use the same degree of care and skill in their
exercise, as a prudent man would exercise or use under the circumstances in the
conduct of his own affairs.

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

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

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

                                       50
<PAGE>

            (3) the Trustee shall not be liable with respect to any action
      taken, suffered or omitted to be taken by it with respect to Debt
      Securities of any series in good faith in accordance with the direction of
      the Holders of a majority in principal amount of the Outstanding Debt
      Securities of such series relating to the time, method and place of
      conducting any proceeding for any remedy available to the Trustee, or
      exercising any trust or power conferred upon the Trustee, under this
      Indenture;

            (4) the Trustee is under no obligation or duty to pay interest on or
      invest any funds deposited with it except as specifically provided in this
      Indenture, and all investment activities undertaken by the Trustee, if
      any, shall be at and pursuant to the written instruction of the Company;
      and

            (5) the Trustee shall not be required 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.

      (d) 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.

      (e) Any opinion required or permitted to be delivered to the Trustee
hereunder may be addressed and delivered to the entity serving as Trustee
hereunder solely in its individual capacity and not in its capacity as Trustee,
fiduciary or as representative of the holders of such Debt Securities and
Coupons issued by the Company.

      SECTION 6.2. NOTICE OF DEFAULTS.

      Within 90 days after the occurrence of any default hereunder with respect
to Debt Securities or Coupons, if any, of any series, the Trustee shall give
notice to all Holders of Debt Securities and Coupons of such series of such
default hereunder known to the Trustee, unless such default shall have been
cured or waived; provided, however, that, except in the case of a default in the
payment of the principal of (or premium, if any) or interest on any Debt
Security or Coupon of such series or in the payment of any sinking fund
installment with respect to Debt Securities of such series, the Trustee shall be
protected in withholding such notice if and so long as the board of directors,
the executive committee or a trust committee of directors and/or Responsible
Officers of the Trustee in good faith determine that the withholding of such
notice is in the interest of the Holders of Debt Securities and of Coupons of
such series; and provided, further, that in the case of any default of the
character specified in Section 5.1(4) with respect to Debt Securities of such
series no such notice to Holders shall be given until at least 90 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.

      Notice given pursuant to this Section 6.2 shall be transmitted by mail:

                                       51
<PAGE>

            (1) to all Registered Holders, as the names and addresses of the
      Registered Holders appear in the Security Register;

            (2) to such Holders of Bearer Securities of any series as have
      within two years preceding such transmission, filed their names and
      addresses with the Trustee for such series for that purpose; and

            (3) to each Holder of a Debt Security of any series whose name and
      address appear in the information preserved at the time by the Trustee in
      accordance with Section 7.2(a) of this Indenture.

      SECTION 6.3. CERTAIN RIGHTS OF TRUSTEE.

      Except as otherwise provided in Section 6.1:

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

      (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 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 in accordance with such advice or Opinion of
Counsel;

      (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 any series pursuant to this Indenture, unless
such Holders shall have offered to the Trustee reasonable security or indemnity
against the costs, expenses and liabilities which might be incurred by it in
compliance with such request or direction;

      (f) the Trustee shall not be bound to make any investigation into the
facts or matters stated in any resolution, Officer's Certificate or other
certificate, statement, instrument, opinion, report, notice, request, direction,
consent, order, bond, debenture, note, other evidence of indebtedness or other
paper or document, unless requested in writing to do so by not less than a
majority of the Holders of the Outstanding Debt Securities affected thereby, 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

                                       52
<PAGE>

be entitled to examine the books, records and premises of the Company,
personally or by agent or attorney; and

      (g) the Trustee may execute any of the trusts or powers hereunder or
perform any duties hereunder either directly or by or through agents or
attorneys and the Trustee shall not be responsible for any misconduct or
negligence on the part of any agent (including any agent appointed pursuant to
Section 3.10(j)) or attorney appointed with due care by it hereunder.

      SECTION 6.4. 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, 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 or Coupons, if any, of any series. The
Trustee shall not be accountable for the use or application by the Company of
any Debt Securities or the proceeds thereof.

      SECTION 6.5. MAY HOLD DEBT SECURITIES.

      The Trustee, any Paying Agent, the Security Registrar or any other agent
of the Company, in its individual or any other capacity, may become the owner or
pledgee of Debt Securities or Coupons, and, subject to Sections 6.8 and 6.13,
may otherwise deal with the Company with the same rights it would have if it
were not Trustee, Paying Agent, Security Registrar or such other agent.

      SECTION 6.6. MONEY HELD IN TRUST.

      Money in any Currency 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 (i) interest on any money received by it hereunder except as otherwise
agreed with the Company or (ii) losses resulting from currency fluctuations or
any investments made pursuant to 6.1(c)(4).

      SECTION 6.7. COMPENSATION AND REIMBURSEMENT.

      The Company agrees:

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

            (2) except as otherwise expressly provided herein, to reimburse the
      trustee in Dollars 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 to the extent of any such

                                       53
<PAGE>

      expense, disbursement or advance as may be attributable to its negligence,
      bad faith or willful misconduct; and

            (3) to indemnify in Dollars 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, except to the extent that any such
      claim or liability may be attributable to the Trustee's negligence, bad
      faith or willful misconduct.

      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
Coupons, if any, upon all property and funds held or collected by the Trustee as
such, except funds held in trust for the payment of amounts due on the Debt
Securities and Coupons.

      The obligations of the Company under this Section 6.7 to compensate and
indemnify the Trustee for expenses, disbursements and advances shall constitute
additional indebtedness under this Indenture and shall survive the satisfaction
and discharge of this Indenture.

      SECTION 6.8. DISQUALIFICATION; CONFLICTING INTERESTS.

      (a) If the Trustee has or shall acquire any conflicting interest, as
defined in this Section 6.8 with respect to the Debt Securities of any series,
then, within 90 days after ascertaining that it has such conflicting interest,
and if the default (as hereinafter defined) to which such conflicting interest
relates has not been cured or duly waived or otherwise eliminated before the end
of such 90-day period, the Trustee shall either eliminate such conflicting
interest or, except as otherwise provided below, resign with respect to the Debt
Securities of such series, and the Company shall take prompt steps to have a
successor appointed, in the manner and with the effect hereinafter specified in
this Article VI.

      (b) In the event that the Trustee shall fail to comply with the provisions
of subsection (a) of this Section with respect to the Debt Securities of any
series, the Trustee shall, within 10 days after the expiration of such 90-day
period, transmit to all Holders of Debt Securities of such series notice of such
failure.

      Notice given pursuant to this Section 6.8(b) shall be transmitted by mail:

            (1) to all Registered Holders, as the names and addresses of the
      Registered Holders appear in the Security Register;

            (2) to such Holders of Bearer Securities of any series as have,
      within two years preceding such transmission, filed their names and
      addresses with the Trustee for such series for that purpose; and

                                       54
<PAGE>

            (3) to each Holder of a Debt Security of any series whose name and
      address appear in the information preserved at the time by the Trustee in
      accordance with Section 7.2(a) of this Indenture.

      (c) For the purposes of this Section, the Trustee shall be deemed to have
a conflicting interest with respect to the Debt Securities of any series, if
there shall exist an Event of Default (as such term is defined herein, but
exclusive of any period of grace or requirement of notice) with respect to such
Debt Securities and:

            (1) the Trustee is trustee under this Indenture with respect to the
      Outstanding Debt Securities of any series other than that series or is
      trustee under another indenture under which any other securities, or
      certificates of interest or participation in any other securities, of the
      Company are outstanding, unless such other indenture is a collateral trust
      indenture under which the only collateral consists of Debt Securities
      issued under this Indenture, provided that there shall be excluded from
      the operation of this paragraph this Indenture with respect to the Debt
      Securities of any series other than that series and any other indenture or
      indentures under which other securities, or certificates of interest or
      participation in other securities, of the Company are outstanding, if

                  (i) this Indenture and such other indenture or indentures (and
            all series of securities issuable thereunder) are wholly unsecured
            and rank equally and such other indenture or indentures are
            hereafter qualified under the Trust Indenture Act, unless the
            Commission shall have found and declared by order pursuant to
            Section 305(b) or Section 307(c) of the Trust Indenture Act that
            differences exist between the provisions of this Indenture with
            respect to the Debt Securities of such series and one or more other
            series or the provisions of such other indenture or indentures which
            are so likely to involve a material conflict of interest as to make
            it necessary, in the public interest or for the protection of
            investors to disqualify the Trustee from acting as such under this
            Indenture with respect to the Debt Securities of such series and
            such other series or under such other indenture or indentures, or

                  (ii) the Company shall have sustained the burden of proving,
            on application to the Commission and after opportunity for hearing
            thereon, that trusteeship under this Indenture with respect to the
            Debt Securities of such series and such other series or such other
            indenture or indentures is not so likely to involve a material
            conflict of interest as to make it necessary in the public interest
            or for the protection of investors to disqualify the Trustee from
            acting as such under this Indenture with respect to the Debt
            Securities of such series and such other series or under such other
            indenture or indentures;

            (2) the Trustee or any of its directors or executive officers is an
      underwriter for the Company;

                                       55
<PAGE>

            (3) the Trustee directly or indirectly controls or is directly or
      indirectly controlled by or is under direct or indirect common control
      with an underwriter for the Company;

            (4) the Trustee or any of its directors or executive officers is a
      director, officer, partner, employee, appointee or representative of the
      Company, or of an underwriter (other than the Trustee itself) for the
      Company who is currently engaged in the business of underwriting, except
      that (i) one individual may be a director or an executive officer, or
      both, of the Trustee and a director or an executive officer, or both, of
      the Company but may not be at the same time an executive officer of both
      the Trustee and the Company; (ii) if and so long as the number of
      directors of the Trustee in office is more than nine, one additional
      individual may be a director or an executive officer, or both, of the
      Trustee and a director of the Company; and (iii) the Trustee may be
      designated by the Company or by any underwriter for the Company to act in
      the capacity of transfer agent, registrar, custodian, paying agent, fiscal
      agent, escrow agent, or depositary or in any other similar capacity, or,
      subject to the provisions of paragraph (l) of this subsection, to act as
      trustee, whether under an indenture or otherwise;

            (5) 10% or more of the voting securities of the Trustee is
      beneficially owned either by the Company or by any director, partner or
      executive officer thereof, or 20% or more of such voting securities is
      beneficially owned, collectively, by any two or more of such persons; or
      10% or more of the voting securities of the Trustee is beneficially owned
      either by an underwriter for the Company or by any director, partner or
      executive officer thereof or is beneficially owned, collectively, by any
      two or more such persons;

            (6) the Trustee is the beneficial owner of, or holds as collateral
      security for an obligation which is in default (as hereinafter in this
      subsection defined), (i) 5% or more of the voting securities, or 10% or
      more of any other class of security, of the Company not including the Debt
      Securities issued under this Indenture and securities issued under any
      other indenture under which the Trustee is also trustee, or (ii) 10% or
      more of any class of security of an underwriter for the Company;

            (7) the Trustee is the beneficial owner of or holds as collateral
      security for an obligation which is in default, 5% or more of the voting
      securities of any person who, to the knowledge of the Trustee, owns 10% or
      more of the voting securities of, or controls directly or indirectly or is
      under direct or indirect common control with, the Company;

            (8) the Trustee is the beneficial owner of or holds as collateral
      security for an obligation which is in default, 10% or more of any class

      or more of the voting securities of the Company;

                                       56
<PAGE>

            (9) the Trustee owns, on the date of such Event of Default or any
      anniversary of such Event of Default while such Event of Default remains
      outstanding, in the capacity of executor, administrator, testamentary or
      inter vivos trustee, guardian, committee or conservator, or in any other
      similar capacity, an aggregate of 25% or more of the voting securities, or
      of any class of security, of any person, the beneficial ownership of a
      specified percentage of which would have constituted a conflicting
      interest under paragraph (6), (7) or (8) of this subsection. As to any
      such securities of which the Trustee acquired ownership through becoming
      executor, administrator or testamentary trustee of an estate which
      included them, the provisions of the preceding sentence shall not apply,
      for a period of not more than two years from the date of such acquisition,
      to the extent that such securities included in such estate do not exceed
      25% of such voting securities or 25% of any such class of security.
      Promptly after the dates of any such Event of Default and annually in each
      succeeding year that such Event of Default continues, the Trustee shall
      make a check of its holdings of such securities in any of the
      above-mentioned capacities as of such dates. If the Company fails to make
      payment in full of the principal of (or premium, if any) or interest on
      any of the Debt Securities when and as the same becomes due and payable,
      and such failure continues for 30 days thereafter, the Trustee shall make
      a prompt check of its holdings of such securities in any of the
      above-mentioned capacities as of the date of the expiration of such 30-day
      period, and after such date, notwithstanding the foregoing provisions of
      this paragraph, all such securities so held by the Trustee, with sole or
      joint control over such securities vested in it, shall be considered as
      though beneficially owned by the Trustee for the purposes of paragraphs
      (6), (7) and (8) of this subsection; or

            (10) except under the circumstances described in paragraphs (1),
      (3), (4), (5) or (6) of Section 6.13(b) of this Indenture, the Trustee
      shall be or shall become a creditor of the Company.

      For the purposes of paragraph (1) of this subsection, the term "series of
securities" or "series" means a series, class or group of securities issuable
under an indenture pursuant to whose terms holders of one such series may vote
to direct the Trustee, or otherwise take action pursuant to a vote of such
holders, separately from holders of another series; provided, that "series of
securities" or "series" shall not include any series of securities issuable
under an indenture if all such series rank equally and are wholly unsecured.

      The specification of percentages in paragraphs (5) to (9), inclusive, of
this subsection shall not be construed as indicating that the ownership of such
percentages of the securities of a person is or is not necessary or sufficient
to constitute direct or indirect control for the purposes of paragraph (3) or
(7) of this subsection.

      For the purposes of paragraphs (6), (7), (8) and (9) of this subsection
only, (i) the terms "security" and "securities" shall include only such
securities as are generally known as corporate securities, but shall not include
any note or other evidence of indebtedness issued to evidence an obligation to
repay moneys lent to a person by one or more banks, trust companies or banking
firms, or any certificate of interest or participation in any such note or
evidence of indebtedness;

                                       57
<PAGE>

(ii) an obligation shall be deemed to be "in default" when a default in payment
of principal shall have continued for 30 days or more and shall not have been
cured; and (iii) the Trustee shall not be deemed to be the owner or holder of
(A) any security which it holds as collateral security, as trustee or otherwise,
for an obligation which is not in default as defined in clause (ii) above, or
(B) any security which it holds as collateral security under this Indenture,
irrespective of any default hereunder, or (C) any security which it holds as
agent for collection, or as custodian, escrow agent or depositary, or in any
similar representative capacity.

      (d) For the purposes of this Section:

            (1) The term "underwriter" when used with reference to the Company
      means every person who, within one year prior to the time as of which the
      determination is made, has purchased from the Company with a view to, or
      has offered or sold for the Company in connection with, the distribution
      of any security of the Company outstanding at such time, or has
      participated or has had a direct or indirect participation in any such
      undertaking, or has participated or has had a participation in the direct
      or indirect underwriting of any such undertaking, but such term shall not
      include a person whose interest was limited to a commission from an
      underwriter or dealer not in excess of the usual and customary
      distributors' or sellers' commission.

            (2) The term "director" means any director of a corporation, or any
      individual performing similar functions with respect to any organization
      whether incorporated or unincorporated.

            (3) The term "person" means an individual, a corporation, a
      partnership, an association, a joint stock company, a trust, an estate, an
      unincorporated organization, or a government or political subdivision
      thereof. As used in this paragraph, the term "trust" shall include only a
      trust where the interest or interests of the beneficiary or beneficiaries
      are evidenced by a security.

            (4) The term "voting security" means any security presently
      entitling the owner or holder thereof to vote in the direction or
      management of the affairs of a person, or any security issued under or
      pursuant to any trust, agreement or arrangements whereby a trustee or
      trustees or agent or agents for the owner or holder of such security are
      presently entitled to vote in the direction or management of the affairs
      of a person.

      directors.

      (e) The percentages of voting securities and other securities specified in
this Section shall be calculated in accordance with the following provisions:

            (1) A specified percentage of the voting securities of the Trustee,
      the Company or any other person referred to in this Section (each of whom
      is referred to as a "person" in this paragraph) means such amount of the
      outstanding voting securities of such person as entitles the holder or
      holders thereof to cast such specified percentage of the aggregate votes
      which the holders of all the outstanding voting securities of such person
      are entitled to cast in the direction or management of the affairs of such
      person.

            (2) A specified percentage of a class of securities of a person
      means such percentage of the aggregate amount of securities of the class
      outstanding.

            (3) The term "amount," when used with regard to securities means the
      principal amount if relating to evidences of indebtedness, the number of
      shares if relating to capital shares, and the number of units if relating
      to any other kind of security.

            (4) The term "outstanding" means issued and not held by or for the
      account of the issuer. The following securities shall not be deemed
      outstanding within the meaning of this definition:

                  (i) securities of an issuer held in a sinking fund relating to
            securities of the issuer of the same class;

                  (ii) securities of an issuer held in a sinking fund relating
            to another class of securities of the issuer, if the obligation
            evidenced by such other class of securities is not in default as to
            principal or interest or otherwise;

                  (iii) securities pledged by the issuer thereof as security for
            an obligation of the issuer not in default as to principal or
            interest or otherwise; and

                  (iv) securities held in escrow if placed in escrow by the
            issuer thereof;

      provided, however, that any voting securities of an issuer shall be deemed
      outstanding if any person other than the issuer is entitled to exercise
      the voting rights thereof.

            (5) A security shall be deemed to be of the same class as another
      security if both securities confer upon the holder or holders thereof
      substantially the same rights and privileges; provided, however, that, in
      the case of secured evidences of indebtedness, all of which are issued
      under a single indenture, differences in the interest rates or maturity
      dates of various series thereof shall not be deemed sufficient to
      constitute such series different classes; and provided,

                                       59
<PAGE>

      further, that, in the case of unsecured evidences of indebtedness,
      differences in the interest rates or maturity dates thereof shall not be
      deemed sufficient to constitute them securities of different classes,
      whether or not they are issued under a single indenture. Nothing in the
      forgoing shall in anyway whatsoever affect whether a security shall be
      deemed to be of the same class as another security for purposes of Section
      13 of the Securities Exchange Act of 1934 and Rule 13a-3 thereunder or
      otherwise under federal securities laws.

      (f) Except in the case of a default in the payment of the principal of or
interest on any Debt Security of any series, or in the payment of any sinking or
purchase fund installment, the Trustee shall not be required to resign as
provided by this Section if the Trustee shall have sustained the burden of
proving, on application to the Commission and after opportunity for hearing
thereon, that:

            (1) the Event of Default may be cured or waived during a reasonable
      period and under the procedures described in such application; and

            (2) a stay of the Trustee's duty to resign will not be inconsistent
      with the interests of Holders of the Debt Securities.

The filing of such an application shall automatically stay the performance of
the duty to resign until the Commission orders otherwise.

      SECTION 6.9. CORPORATE TRUSTEE REQUIRED; ELIGIBILITY.

      There shall at all times be a Trustee hereunder which shall be a
corporation organized and doing business under the laws of the United States of
America, any State thereof or the District of Columbia, authorized under such
laws to exercise corporate trust powers, having a combined capital and surplus
of at least $75,000,000, subject to supervision or examination by Federal, State
or District of Columbia authority. 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. Neither the Company nor any person directly or
indirectly controlling, controlled by, or under common control with the Company
shall serve as Trustee upon any Debt Securities.

      SECTION 6.10. RESIGNATION AND REMOVAL; APPOINTMENT OF SUCCESSOR.

      (a) No resignation or removal of the Trustee and no appointment of a
successor Trustee pursuant to this Article VI shall become effective until the
acceptance of appointment by the successor Trustee under Section 6.11.

      (b) The Trustee may resign at any time with respect to the 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.

                                       60
<PAGE>

      (c) The Trustee may be removed at any time with respect to the Debt
Securities of any series and a successor Trustee appointed 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 6.8(a) 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 6.9 with
      respect to the Debt Securities of any series and shall fail to resign
      after written request therefor by the Company or by any such Holder, or

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

then, in any such case, (i) the Company by a Board Resolution may remove the
Trustee with respect to all Debt Securities, or (ii) subject to Section 5.14,
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 and
the appointment of a successor Trustee for the Debt Securities of such series.

      (e) If the Trustee shall resign, be removed or become incapable of acting,
or if a vacancy shall occur in the office of Trustee for any cause, with respect
to the Debt Securities of 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 6.11. If, within one year
after such resignation, removal or incapability, or the 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 of such series 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 5.14, 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.

                                       61
<PAGE>

      (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 in the manner and to the extent provided in Section 1.5 to the Holders of
Debt Securities of such series. 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 6.11. ACCEPTANCE OF APPOINTMENT BY SUCCESSOR.

      (a) In the case of an appointment hereunder of a successor Trustee with
respect to all Debt Securities, each 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, subject nevertheless to its
claim, if any, provided for in Section 6.7.

      (b) In 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 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 any such supplemental indenture shall
constitute such Trustees co-trustees of the same trust and that each such
Trustee shall be trustee of a trust or trusts hereunder separate and apart from
any other trust or trusts hereunder administered by any other such Trustee; and
upon the execution and delivery of any 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 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.

                                       62
<PAGE>

      (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 6.11, 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 VI.

      SECTION 6.12. MERGER, CONVERSION, CONSOLIDATION OR SUCCESSION TO BUSINESS.

      Any corporation into which the Trustee may be merged or converted or with
which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the trustee shall be a party, or any
corporation succeeding to all or substantially all of the corporate trust
business of the Trustee, shall be the successor of the Trustee hereunder,
provided that such corporation shall be otherwise qualified and eligible under
this Article VI, without the execution 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 or consolidation 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.

      SECTION 6.13. PREFERENTIAL COLLECTION OF CLAIMS AGAINST COMPANY.

      (a) Subject to subsection (b) of this Section 6.13, if the Trustee shall
be or shall become a creditor, directly or indirectly, secured or unsecured, of
the Company within three months prior to a default, as defined in subsection (c)
of this Section 6.13, or subsequent to such default, then, unless and until such
default shall be cured, the Trustee shall set apart and hold in a special
account for the benefit of the Trustee individually, the Holders of the Debt
Securities and of the Coupons, if any, and the holders of other indenture
securities (as defined in subsection (c) of this Section 6.13):

            (1) an amount equal to any and all reductions in the amount due and
      owing upon any claim as such creditor in respect of principal or interest,
      effected after the beginning of such three-month period and valid as
      against the Company and its other creditors, except any such reduction
      resulting from the receipt or disposition of any property described in
      paragraph (2) of this subsection, or from the exercise of any right of
      set-off which the Trustee could have exercised if a voluntary or
      involuntary case had been commenced in respect of the Company under the
      Federal bankruptcy laws, as now or hereafter constituted, or any other
      applicable Federal or State bankruptcy, insolvency or other similar law
      upon the date of such default; and

                                       63
<PAGE>

            (2) all property received by the Trustee in respect of any claim as
      such creditor, either as security therefor, or in satisfaction or
      composition thereof, or otherwise, after the beginning of such three-month
      period, or an amount equal to the proceeds of any such property, if
      disposed of, subject, however, to the rights, if any, of the Company and
      its other creditors in such property or such proceeds.

Nothing herein contained, however, shall affect the right of the Trustee:

            (A) to retain for its own account (i) payments made on account of
      any such claim by any Person (other than the Company) who is liable
      thereon, and (ii) the proceeds of the bona fide sale of any such claim by
      the Trustee to a third Person, and (iii) distributions made in cash,
      securities or other property in respect of claims filed against the
      Company in bankruptcy or receivership or in proceedings or reorganization
      pursuant to the Federal bankruptcy laws, as now or hereafter constituted,
      or any other applicable Federal or State bankruptcy, insolvency or other
      similar law;

            (B) to realize, for its own account, upon any property held by it as
      security for any such claim, if such property was so held prior to the
      beginning of such three-month period;

            (C) to realize, for its own account, but only to the extent of the
      claim hereinafter mentioned, upon any property held by it as security for
      any such claim, if such claim was created after the beginning of such
      three-month period and such property was received as security therefor
      simultaneously with the creation thereof, and if the Trustee shall sustain
      the burden of proving that at the time such property was so received the
      Trustee had no reasonable cause to believe that a default, as defined in
      subsection (c) of this Section, would occur within three months; or

            (D) to receive payment on any claim referred to in paragraph (B) or
      (C) against the release of any property held as security for such claim as
      provided in paragraph (B) or (C), as the case may be, to the extent of the
      fair value of such property.

      For the purposes of paragraphs (B), (C) and (D), property substituted
after the beginning of such three-month period for property held as security at
the time of such substitution shall, to the extent of the fair value of the
property released, have the same status as the property released, and, to the
extent that any claim referred to in any of such paragraphs is created in
renewal of or in substitution for or for the purpose of repaying or refunding
any pre-existing claim of the Trustee as such creditor, such claim shall have
the same status as such pre-existing claim.

      If the Trustee shall be required to account, the funds and property held
in such special account and the proceeds thereof shall be apportioned among the
Trustee, the Holders and the holders of other indenture securities in such
manner that the Trustee, the Holders and the holders of other indenture
securities realize, as a result of payments from such special account and
payments of dividends on claims filed against the Company in bankruptcy or
receivership or in

                                       64
<PAGE>

proceedings for reorganization pursuant to the Federal bankruptcy laws, as now
or hereafter constituted or any other applicable Federal or State bankruptcy,
insolvency or other similar law, the same percentage of their respective claims,
figured before crediting to the claim of the Trustee anything on account of the
receipt by it from the Company of the funds and property in such special account
and before crediting to the respective claims of the Trustee and the Holders and
the holders of other indenture securities dividends on claims filed against the
Company in bankruptcy or receivership or in proceedings for reorganization
pursuant to the Federal bankruptcy laws, as now or hereafter constituted, or any
other applicable Federal or State bankruptcy, insolvency or other similar law,
but after crediting thereon receipts on account of the indebtedness represented
by their respective claims from all sources other than from such dividends and
from the funds and property so held in such special account. As used in this
paragraph, with respect to any claim, the term "dividends" shall include any
distribution with respect to such claim, in bankruptcy or receivership or in
proceedings for reorganization pursuant to the Federal bankruptcy laws, as now
or hereafter constituted, or any other applicable Federal or State bankruptcy,
insolvency or other similar law, whether such distribution is made in cash,
securities, or other property, but shall not include any such distribution with
respect to the secured portion, if any, of such claim. The court in which such
bankruptcy, receivership or proceedings for reorganization is pending shall have
jurisdiction (i) to apportion among the Trustee and the Holders and the holders
of other indenture securities, in accordance with the provisions of this
paragraph, the funds and property held in such special account and proceeds
thereof, or (ii) in lieu of such apportionment, in whole or in part, to give to
the provisions of this paragraph due consideration in determining the fairness
of the distributions to be made to the Trustee and the Holders and the holders
of other indenture securities with respect to their respective claims, in which
event it shall not be necessary to liquidate or to appraise the value of any
securities or other property held in such special account or as security for any
such claim, or to make a specific allocation of such distributions as between
the secured and unsecured portions of such claim, or otherwise to apply the
provisions of this paragraph as a mathematical formula.

      Any Trustee which has resigned or been removed after the beginning of such
three-month period shall be subject to the provisions of this subsection as
though such resignation or removal had not occurred. If any Trustee has resigned
or been removed prior to the beginning of such three-month period, it shall be
subject to the provisions of this subsection if and only if the following
conditions exist:

            (i) the receipt of property or reduction of claim, which would have
      given rise to the obligation to account, if such Trustee had continued as
      Trustee, occurred after the beginning of such three-month period; and

            (ii) such receipt of property or reduction of claim occurred within
      three months after such resignation or removal.

      (b) There shall be excluded from the operation of subsection (a) of this
Section 6.13 a creditor relationship arising from:

            (1) the ownership or acquisition of securities issued under any
      indenture, or any security or securities having a maturity of one year or
      more at the time of acquisition by the Trustee;

                                       65
<PAGE>

            (2) advances authorized by a receivership or bankruptcy court of
      competent jurisdiction or by this Indenture, for the purpose of preserving
      any property which shall at any time be subject to this Indenture or of
      discharging tax liens or other prior liens or encumbrances thereon, if
      notice of such advances and of the circumstances surrounding the making
      thereof is given to the Holders at the time and in the manner provided in
      this Indenture;

            (3) disbursements made in the ordinary course of business in the
      capacity of trustee under an indenture, transfer agent, registrar,
      custodian, paying agent, fiscal agent or depositary, or other similar
      capacity;

            (4) an indebtedness created as a result of services rendered or
      premises rented, or an indebtedness created as a result of goods or
      securities sold in a cash transaction as defined in subsection (c) of this
      Section 6.13;

            (5) the ownership of stock or of other securities of a corporation
      organized under the provisions of Section 25(a) of the Federal Reserve
      Act, as amended, which is directly or indirectly a creditor of the
      Company; and

            (6) The acquisition, ownership, acceptance or negotiation of any
      drafts, bills of exchange, acceptances or obligations which fall within
      the classification of self-liquidating paper as defined in subsection (c)
      of this Section 6.13.

      (c) for the purposes of this Section 6.13 only:

            (1) The term "default" means any failure to make payment in full of
      the principal of or interest on any of the Debt Securities or upon the
      other indenture securities when and as such principal or interest becomes
      due and payable.

            (2) The term "other indenture securities" means securities upon
      which the Company is an obligor outstanding under any other indenture (i)
      under which the Trustee is also trustee, (ii) which contains provisions
      substantially similar to the provisions of this Section 6.13, and (iii)
      under which a default exists at the time of the apportionment of the funds
      and property held in such special account.

            (3) The term "cash transaction" means any transaction in which full
      payment for goods or securities sold is made within seven days after
      delivery of the goods or securities in currency or in checks or other
      orders drawn upon banks or bankers and payable upon demand.

            (4) The term "self-liquidating paper" means any draft, bill of
      exchange, acceptance or obligation which is made, drawn, negotiated or
      incurred by the Company for the purpose of financing the purchase,
      processing, manufacturing, shipment, storage or sale of goods, wares or
      merchandise and which is secured by documents evidencing title to,
      possession of, or a lien upon the goods, wares or merchandise or the
      receivables or proceeds arising from the

                                       66
<PAGE>

      sale of the goods, wares or merchandise or the receivables or proceeds
      arising from the sale of the goods, wares or merchandise, previously
      constituting the security, provided the security is received by the
      Trustee simultaneously with the creation of the creditor relationship with
      the Company arising from the making, drawing, negotiating or incurring of
      the draft, bill of exchange, acceptance or obligation.

            (5) The term "Company" means any obligor upon the Debt Securities.

      SECTION 6.14. APPOINTMENT OF AUTHENTICATING AGENT.

      As long as any Debt Securities of a series remain Outstanding, upon a
Company Request, there shall be an authenticating agent (the "Authenticating
Agent") appointed, for such period as the Company shall elect, by the Trustee
for such series of Debt Securities to act as its agent on its behalf and subject
to its direction in connection with the authentication and delivery of each
series of Debt Securities for which it is serving as Trustee. Debt Securities of
each such series authenticated by such Authenticating Agent shall be entitled to
the benefits of this Indenture and shall be valid and obligatory for all
purposes as if authenticated by such Trustee. Wherever reference is made in this
Indenture to the authentication and delivery of Debt Securities of any series by
the Trustee for such series or to the Trustee's Certificate of Authentication,
such reference shall be deemed to include authentication and delivery on behalf
of the Trustee for such series by an Authenticating Agent for such series and a
Certificate of Authentication executed on behalf of such Trustee by such
Authenticating Agent, except that only the Trustee may authenticate Debt
Securities upon original issuance and pursuant to Section 3.6 hereof. Such
Authenticating Agent shall at all times be a corporation organized and doing
business under the laws of the United States of America or of any State,
authorized under such laws to exercise corporate trust powers, having a combined
capital and surplus of at least $10,000,000 and subject to supervision or
examination by Federal or State authority. If such Authenticating Agent
publishes reports of condition at least annually, pursuant to law or to the
requirements of said supervising or examining authority, then for purposes of
this Section, the combined capital and surplus of such Authenticating Agent
shall be deemed to be its combined capital and surplus as set forth in its most
recent report of condition so published. If at any time an Authenticating Agent
shall cease to be eligible in accordance with the provisions of this Section,
such Authenticating Agent shall resign immediately in the manner and with the
effect specified in this Section.

      Any corporation into which any Authenticating Agent may be merged or
converted, or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which any Authenticating Agent
shall be a party, or any corporation succeeding to the corporate agency business
of any Authenticating Agent, shall continue to be the Authenticating Agent with
respect to all series of Debt Securities for which it served as Authenticating
Agent without the execution or filing of any paper or any further act on the
part of the Trustee for such series or such Authenticating Agent. Any
Authenticating Agent may at any time, and if it shall cease to be eligible
shall, resign by giving written notice of resignation to the applicable Trustee
and to the Company.

                                       67

      Upon receiving such a notice of resignation or upon such a termination, or
in case at any time any Authenticating Agent shall cease to be eligible in
accordance with the provisions of this Section 6.14 with respect to one or more
or all series of Debt Securities, the Trustee for such series shall upon Company
Request appoint a successor Authenticating Agent, and the Company shall provide
notice of such appointment to all Holders of Debt Securities of such series in
the manner and to the extent provided in Section 1.5. Any successor
Authenticating Agent upon acceptance of its appointment hereunder shall become
vested with all rights, powers, duties and responsibilities of its predecessor
hereunder, with like effect as if originally named as Authenticating Agent
herein. The Trustee for the Debt Securities of such series agrees to pay to the
Authenticating Agent for such series from time to time reasonable compensation
for its services, and the Trustee shall be entitled to be reimbursed for such
payment, subject to the provisions of Section 6.7. The Authenticating Agent for
the Debt Securities of any series shall have no responsibility or liability for
any action taken by it as such at the direction of the Trustee for such series.

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

      This is one of the series of Debt Securities issued under the within
mentioned Indenture.

                                               Authorized Signatory

                                  ARTICLE VII.

                HOLDERS' LISTS AND REPORTS BY TRUSTEE AND COMPANY

      SECTION 7.1. COMPANY TO FURNISH TRUSTEE NAMES AND ADDRESSES OF HOLDERS.

      The Company will furnish or cause to be furnished to the Trustee with
respect to Registered Securities of each series for which it acts as Trustee:

      (a) semi-annually on a date not more than 15 days after each Regular
Record Date with respect to an Interest Payment Date, if any, for the Registered
Securities of such series (or on semi-annual dates in each year to be determined
pursuant to Section 3.1 if the Registered Securities of such series do not bear
interest), a list, in such form as the Trustee may reasonably require, of the
names and addresses of the Registered Holders as of the date 15 days next
preceding each such Regular Record Date (or such semi-annual dates, as the case
may be); and

      (b) at such other times as the Trustee may request in writing, within 30
days after the receipt by the Company of any such request, a list of similar
form and content as of a date not more than 15 days prior to the time such list
is furnished;

                                       68
<PAGE>

provided, however, that if and so long as the Trustee shall be the Security
Registrar for such series, no such list need be furnished.

      The Company shall also be required to furnish to the Trustee at all such
times set forth above all information in the possession or control of the
Company or any of its Paying Agents other than the Trustee as to the names and
addresses of the Holders of Bearer Securities of all series; provided, however,
that the Company shall have no obligation to investigate any matter relating to
any Holders of Bearer Securities of any series.

      SECTION 7.2. PRESERVATION OF INFORMATION, COMMUNICATION TO HOLDERS.

      (a) The Trustee shall preserve, in as current a form as is reasonably
practicable, all information as to the names and addresses of Holders contained
in the most recent list furnished to the Trustee as provided in Section 7.1
received by it in the capacity of Paying Agent (if so acting) hereunder, and
filed with it within the two preceding years pursuant to Section 7.3(c)(2).

      The Trustee may destroy any list furnished to it as provided in Section
7.1 upon receipt of a new list so furnished, destroy any information received by
it as Paying Agent (if so acting) hereunder upon delivering to itself as
Trustee, not earlier than 45 days after an Interest Payment Date, a list
containing the names and addresses of the Holders obtained from such information
since the delivery of the next previous list, if any, destroy any list delivered
to itself as Trustee which was compiled from information received by it as
Paying Agent (if so acting) hereunder upon the receipt of a new list so
delivered, and destroy not earlier than two years after filing, any information
filed with it pursuant to Section 7.3(c)(2).

      (b) If three or more Holders (hereinafter referred to as "applicants")
apply in writing to the Trustee, and furnish to the Trustee reasonable proof
that each such applicant has owned a Debt Security for a period of at least six
months preceding the date of such application, and such application states that
the applicants desire to communicate with other Holders of Debt Securities of a
particular series (in which case the applicants must hold Debt Securities of
such series) or with all Holders of Debt Securities with respect to their rights
under this Indenture or under the Debt Securities and is accompanied by a copy
of the form of proxy or other communication which such applicants propose to
transmit, then the Trustee shall, within five Business Days after the receipt of
such application, at its election, either

            (i) afford such applicants access to the information preserved at
      the time by the Trustee in accordance with Section 7.2(a), or

            (ii) inform such applicants as to the approximate number of Holders
      of Debt Securities of such series or of all Debt Securities, as the case
      may be, whose names and addresses appear in the information preserved at
      the time by the Trustee in accordance with Section 7.2(a), and as to the
      approximate cost of mailing to such Holders the form of proxy or other
      communication, specified in such application.

      If the Trustee shall elect not to afford such applicants access to such
information, the Trustee shall, upon written request of such applicants, mail to
the Holders of Debt Securities of such series or all Holders, as the case may
be, whose names and addresses appear in the

                                       69
<PAGE>

information preserved at the time by the Trustee in accordance with Section
7.2(a), a copy of the form of proxy or other communication which is specified in
such request, with reasonable promptness after a tender to the Trustee of the
material to be mailed and of payment, or provision for the payment, of the
reasonable expenses of mailing, unless within five days after such tender, the
Trustee shall mail to such applicants and file with the Commission, together
with a copy of the material to be mailed, a written statement to the effect
that, in the opinion of the Trustee, such mailing would be contrary to the best
interests of the Holders of Debt Securities of such series or all Holders, as
the case may be, or would be in violation of applicable law. Such written
statement shall specify the basis of such opinion. If the Commission, after
opportunity for a hearing upon the objections specified in the written statement
so filed, shall enter an order refusing to sustain any of such objections or if
after the entry of an order sustaining one or more of such objections, the
Commission shall find, after notice and opportunity for hearing, that all the
objections so sustained have been met and shall enter an order so declaring, the
Trustee shall mail copies of such material to all such Holders with reasonable
promptness after the entry of such order and the renewal of such tender;
otherwise the Trustee shall be relieved of any obligation or duty to such
applicants respecting their application.

      (c) Every Holder of Debt Securities, by receiving and holding the same,
agrees with the Company and the Trustee that neither the Company nor the Trustee
shall be held accountable by reason of the disclosure of any such information as
to the names and addresses of the Holders in accordance with Section 7.2(b),
regardless of the source from which such information was derived, and that the
Trustee shall not be held accountable by reason of mailing of any material
pursuant to a request made under Section 7.2(b).

      SECTION 7.3. REPORTS BY TRUSTEE.

      (a) Within 60 days after January 15 of each year, commencing with the
later of January 15, 2006, or the first January 15 after the first issuance of
Debt Securities pursuant to this Indenture, the Trustee shall, to the extent
required by the Trust Indenture Act, transmit to all Holders of Debt Securities
of any series with respect to which it acts as Trustee, in the manner
hereinafter provided in this Section 7.3, a brief report dated such date with
respect to any of the following events which may have occurred within the
previous 12 months (but if no such event has occurred within such period no

            (1) any change to its eligibility under Section 6.9 and its
      qualifications under Section 6.8;

            (2) the creation of or any material change to a relationship
      specified in paragraph (1) through (10) of Section 6.8(c) of this
      Indenture;

            (3) the character and amount of any advances (and if the Trustee
      elects so to state, the circumstances surrounding the making thereof) made
      by the Trustee (as such) which remain unpaid on the date of such report,
      and for the reimbursement of which it claims or may claim a lien or
      charge, prior to that of the Debt Securities of such series, on any
      property or funds held or collected by it as Trustee, except that the
      Trustee shall not be required (but may elect) to report such advances if
      such advances so remaining unpaid aggregate not more than 1/2

                                       70
<PAGE>

      of 1% of the principal amount of the Outstanding Debt Securities of such
      series on the date of such report;

            (4) any change to the amount, interest rate and maturity date of all
      other indebtedness owing by the Company (or any other obligor on the Debt
      Securities of such series) to the Trustee in its individual capacity, on
      the date of such report, with a brief description of any property held as
      collateral security therefor, except an indebtedness based upon a creditor
      relationship arising in any manner described in Section 6.13(b)(2), (3),
      (4) or (6);

            (5) any change to the property and funds, if any, physically in the
      possession of the Trustee as such on the date of such report;

            (6) any additional issue of Debt Securities which the Trustee has
      not previously reported; and

            (7) any action taken by the Trustee in the performance of its duties
      hereunder which it has not previously reported and which in its opinion
      materially affects the Debt Securities of such series, except action in
      respect of a default, notice of which has been or is to be withheld by the
      Trustee in accordance with Section 6.2.

      (b) The Trustee shall transmit by mail to all Holders of Debt Securities
of any series (whose names and addresses appear in the information preserved at
the time by the Trustee in accordance with Section 7.2(a)) for which it acts as
the Trustee, as hereinafter provided, a brief report with respect to the
character and amount of any advances (and if the Trustee elects so to state, the
circumstances surrounding the making thereof) made by the Trustee (as such)
since the date of the last report transmitted pursuant to subsection (a) of this
Section (or if no such report has yet been so transmitted, since the date of
execution of this instrument) for the reimbursement of which it claims or may
claim a lien or charge, prior to that of the Debt Securities of such series, on
property or funds held or collected by it as Trustee, and which it has not
previously reported pursuant to this subsection, except that the Trustee for
each series shall not be required (but may elect) to report such advances if
such advances remaining unpaid at any time aggregate 10% or less of the
principal amount of the Debt Securities of such series Outstanding at such time,
such report to be transmitted within 90 days after such time.

      (c) Reports pursuant to this Section 7.3 shall be transmitted by mail:

            (1) to all Holders of Registered Securities, as the names and
      addresses of such Holders of Registered Securities appear in the Security
      Register;

            (2) to such Holders of Bearer Securities of any series as have,
      within two years preceding such transmission, filed their names and
      addresses with the Trustee for such series for that purpose; and

            (3) except in the cases of reports pursuant to subsection (b) of
      this Section 7.3, to each Holder of a Debt Security of any series whose
      name and

                                       71
<PAGE>

      address appear in the information preserved at the time by the Trustee in
      accordance with Section 7.2(a).

      (d) A copy of each such report shall, at the time of such transmission to
Holders, be filed with the Company and the Company shall file such report with
each stock exchange, if any, upon which any Debt Securities of such series are
listed, with the Commission and also with the Company. The Company will notify
the Trustee when any series of Debt Securities are listed on any stock exchange
and of any delisting thereof.

      SECTION 7.4. REPORTS BY COMPANY.

      Unless otherwise specified with respect to a particular series of Debt
Securities pursuant to Section 3.1, the Company will:

            (1) file with the Trustee, after the Company is required to file the
      same with the Commission, copies of the annual reports and of the
      information, documents and other reports (or copies of such portions of
      any of the foregoing as the Commission may from time to time by rules and
      regulations prescribe) which the Company may be required to file with the
      Commission pursuant to Section 13 or Section 15(d) of the Securities
      Exchange Act of 1934, as amended. Notwithstanding that the Company may not
      be required to remain subject to the reporting requirements of Section 13
      or 15(d) of the Securities Exchange Act of 1934, as amended, or otherwise
      report on an annual and quarterly basis on forms provided for such annual
      and quarterly reporting pursuant to rules and regulations promulgated by
      the Commission, the Company shall continue to file with the Commission and
      provide the Trustee and the Holders of each series of Debt Securities
      with, without cost to each Holder, (a) within 90 days after the end of
      each fiscal year, annual reports on Form 10-K (or any successor or
      comparable form) containing the information required to be contained
      therein (or required in such successor or comparable form); (b) within 45
      days after the end of each of the first three fiscal quarters of each
      fiscal year, reports on Form 10-Q (or any successor or comparable form);
      and (c) promptly from time to time after the occurrence of an event
      required to be therein reported, such other reports on Form 8-K (or any
      successor or comparable form) containing the information required to be
      contained therein (or required in any successor or comparable form);
      provided, however, that the Company shall not be obligated to file such
      reports with the Commission if the Commission does not permit such
      filings. The Company will in all cases, without cost to each recipient,
      provide copies of such information to the Holders of the Debt Securities
      of each series and, if they are not permitted to file such reports with
      the Commission, shall make available information to prospective purchasers
      and to securities analysts and broker-dealers upon their request;

            (2) file with the Trustee and the Commission, in accordance with
      rules and regulations prescribed from time to time by the Commission, such
      additional information, documents and reports with respect to compliance
      by the Company

                                       72
<PAGE>

      with the conditions and covenants of this Indenture as may be required
      from time to time by such rules and regulations; and

            (3) transmit to all Holders of Debt Securities, in the manner and to
      the extent provided in Section 7.3, within 30 days after the filing
      thereof with the Trustee, such summaries of any information, documents and
      reports required to be filed by the Company pursuant to paragraphs (1) and
      (2) of this Section as may be required by rules and regulations prescribed
      from time to time by the Commission.

                                  ARTICLE VIII.

                             CONCERNING THE HOLDERS

      SECTION 8.1. ACTS OF HOLDERS.

      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 or proxy duly appointed in
writing; and, except as herein otherwise expressly provided, such action shall
become effective when such instrument or instruments are delivered to the
Trustee, and, where it is hereby expressly required, to the Company. Such
instrument or instruments (and the action embodied therein and evidenced
thereby) are herein sometimes referred to as the "Act" of the Holders signing
such instrument or instruments. Whenever in this Indenture it is provided that
the Holders of a specified percentage in aggregate principal amount of the
Outstanding Debt Securities of any series may take any Act, the fact that the
Holders of such specified percentage have joined therein may be evidenced (a) by
the instrument or instruments executed by Holders in person or by agent or proxy
appointed in writing, or (b) by the record of Holders voting in favor thereof at
any meeting of such Holders duly called and held in accordance with the
provisions of Article IX, or (c) by a combination of such instrument or
instruments and any such record of such a meeting of Holders.

      SECTION 8.2. PROOF OF OWNERSHIP; PROOF OF EXECUTION OF INSTRUMENTS BY
HOLDER.

      The ownership of Registered Securities of any series shall be proved by
the Security Register for such series or by a certificate of the Security
Registrar for such series.

      The ownership of Bearer Securities shall be proved by production of such
Bearer Securities or by a certificate executed by any bank or trust company,
which certificate shall be dated and shall state that on the date thereof a
Bearer Security bearing a specified identifying number or other mark was
deposited with or exhibited to the person executing such certificate by the
person named in such certificate, or by any other proof of possession reasonably
satisfactory to the Trustee. The holding by the person named in any such
certificate of any Bearer Security specified therein shall be presumed to
continue for a period of one year unless at the time of determination of such
holding (1) another certificate bearing a later date issued in respect of the
same Bearer Security shall be produced, (2) such Bearer Security shall be
produced by some other person, (3) such Bearer Security shall have been
registered on the Security Register, if,

                                       73
<PAGE>

pursuant to Section 3.1, such Bearer Security can be so registered, or (4) such
Bearer Security shall have been canceled or paid.

      Subject to the provisions of Sections 6.1, 6.3 and 9.5, proof of the
execution of a writing appointing an agent or proxy and of the execution of any
instrument by a Holder or his agent or proxy shall be sufficient and conclusive
in favor of the Trustee and the Company if made in the following manner:

      The fact and date of the execution by any such person of any instrument
may be proved by the certificate of any notary public or other officer
authorized to take acknowledgements of deeds, that the person executing such
instrument acknowledged to him the execution thereof, or by an affidavit of a
witness to such execution sworn to before any such notary or other such officer.
Where such execution is by an officer of a corporation or association or a
member of a partnership on behalf of such corporation, association or
partnership, as the case may be, or by any other person acting in a
representative capacity, such certificate or affidavit shall also constitute
sufficient proof of his authority.

      The record of any Holders' meeting shall be proved in the manner provided
in Section 9.6.

      The Trustee may in any instance require further proof with respect to any
of the matters referred to in this Section 8.2 so long as the request is a
reasonable one.

      SECTION 8.3. PERSONS DEEMED OWNERS.

      The Company, the Trustee and any agent of the Company or the Trustee may
treat the Person in whose name any Registered Security is registered as the
owner of such Registered Security for the purpose of receiving payment of the
principal of (and premium, if any) and (subject to Section 3.7) interest, if
any, 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 Holder of any Bearer Security or of any Coupon as the absolute
owner of such Bearer Security or Coupon for the purposes of receiving payment
thereof or on account thereof and for all other 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. All payments made to any Holder, or upon his order, shall be
valid, and, to the extent of the sum or sums paid, effectual to satisfy and
discharge the liability for moneys payable upon such Debt Security or Coupon.

      SECTION 8.4. REVOCATION OF CONSENTS; FUTURE HOLDERS BOUND.

      At any time prior to (but not after) the evidencing to the Trustee, as
provided in Section 8.1, of the taking of any Act by the Holders of the
percentage in aggregate principal amount of the Outstanding Debt Securities
specified in this Indenture in connection with such Act, any Holder of a Debt
Security the number, letter or other distinguishing symbol of which is shown by
the evidence to be included in such Debt Securities, the Holders of which have
consented to such Act, by filing written notice with the Trustee at the
Corporate Trust Office and upon proof of

                                       74
<PAGE>

ownership as provided in Section 8.2, may revoke such Act so far as it concerns
such Debt Security. Except as aforesaid, any such Act taken by the Holder of any
Debt Security shall be conclusive and binding upon such Holder and, subject to
the provisions of Section 5.8, upon all future Holders of such Debt Security and
all past, present and future Holders of Coupons, if any, appertaining thereto
and of any Debt Securities and Coupons issued on transfer or in lieu thereof or
in exchange or substitution therefor, irrespective of whether or not any
notation in regard thereto is made upon such Debt Security or Coupons or such
other Debt Securities or Coupons.

                                  ARTICLE IX.

                               HOLDERS' MEETINGS

      SECTION 9.1. PURPOSES OF MEETINGS.

      A meeting of Holders of any or all series may be called at any time and
from time to time pursuant to the provisions of this Article IX for any of the
following purposes:

            (1) to give any notice to the Company or to the Trustee for such
      series, or to give any directions to the Trustee for such series, or to
      consent to the waiving of any default hereunder and its consequences, or
      to take any other action authorized to be taken by Holders pursuant to any
      of the provisions of Article V;

            (2) to remove the Trustee for such series and appoint a successor
      Trustee pursuant to the provisions of Article VI;

            (3) to consent to the execution of an indenture or indentures
      supplemental hereto pursuant to the provisions of Section 11.2; or

            (4) to take any other action authorized to be taken by or on behalf
      of the Holders of any specified aggregate principal amount of the
      Outstanding Debt Securities of any one or more or all series, as the case
      may be, under any other provision of this Indenture or under applicable
      law.

      SECTION 9.2. CALL OF MEETINGS BY TRUSTEE.

      The Trustee for any series may at any time call a meeting of Holders of
such series to take any action specified in Section 9.1, to be held at such time
or times and at such place or places as the Trustee for such series shall
determine. Notice of every meeting of the Holders of any series, setting forth
the time and the place of such meeting and in general terms the action proposed
to be taken at such meeting, shall be given to Holders of such series in the
manner and to the extent provided in Section 1.5. Such notice shall be given not
less than 10 days nor more than 90 days prior to the date fixed for the meeting.

      SECTION 9.3. CALL OF MEETINGS BY COMPANY OR HOLDERS.

requested the Trustee for such series to call a meeting of

                                       75
<PAGE>

Holders of any or all such series by written request setting forth in reasonable
detail the action proposed to be taken at the meeting, and the Trustee shall not
have given the notice of such meeting within 10 days after the receipt of such
request, then the Company or such Holders may determine the time or times and
the place or places for such meetings and may call such meetings to take any
action authorized in Section 9.1, by giving notice thereof as provided in
Section 9.2.

      SECTION 9.4. QUALIFICATIONS FOR VOTING.

      To be entitled to vote at any meeting of Holders a Person shall be (a) a
Holder of a Debt Security of the series with respect to which such meeting is
being held or (b) a Person appointed by an instrument in writing as agent or
proxy by such Holder. The only Persons who shall be entitled to be present or to
speak at any meeting of Holders shall be the Persons entitled to vote at such
meeting and their counsel and any representatives of the Trustee for the series
with respect to which such meeting is being held and its counsel and any
representatives of the Company and its counsel.

      SECTION 9.5. REGULATIONS.

      Notwithstanding any other provisions of this Indenture, the Trustee for
any series may make such reasonable regulations as it may deem advisable for any
meeting of Holders of such series, in regard to proof of the holding of Debt
Securities of such series and of the appointment of proxies, and in regard to
the appointment and duties of inspectors of votes, the submission and
examination of proxies, certificates and other evidence of the right to vote,
and such other matters concerning the conduct of the meeting as it shall deem
appropriate.

      The Trustee shall, by an instrument in writing, appoint a temporary
chairman of the meeting, unless the meeting shall have been called by the
Company or by Holders of such series as provided in Section 9.3, in which case
the Company or the Holders calling the meeting, as the case may be, shall in
like manner appoint a temporary chairman. A permanent chairman and a permanent
secretary of the meeting shall be elected by a majority vote of the meeting.

      Subject to the provisos in the definition of "Outstanding," at any meeting

      any related Coupons in any material respect; or

            (5) to change or eliminate any of the provisions of this Indenture,

      hereunder by a successor Trustee with respect to one or more series of
      Debt Securities 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 6.10; or

            (10) to cure any ambiguity, or to correct or supplement any
      provision herein or in any supplemental indenture that may be defective or
      inconsistent with any other provision herein, to eliminate any conflict

      any, of any series created prior to the execution of such supplemental
      indenture in any material respect.

      SECTION 11.2. SUPPLEMENTAL INDENTURES WITH CONSENT OF HOLDERS.

      With the written consent of the Holders of not less than a majority in

indenture or indentures supplemental hereto for the purpose of adding any
provisions to or changing in any manner or eliminating any of the provisions of
this Indenture or of modifying in any manner the rights of the Holders under
this Indenture of such Debt Securities and Coupons, if any; provided, however,
that no such supplemental indenture shall, without the consent of the Holder of
each Outstanding Debt Security of each such series affected thereby,

            (1) conflict with the required provisions of the Trust Indenture
      Act;

            (2) except as specifically provided with respect to any series of
      Debt Securities pursuant to Section 3.1, (a) change the Stated Maturity of
      the principal of, or installment of interest, if any, on, any Debt
      Security, or (b) reduce the principal amount thereof or the interest

      requirement to offer to repurchase Debt Securities shall not be deemed a
      redemption for this purpose), or (c) change the Stated Maturity of or
      reduce the amount of any payment to be made with respect to any Coupon, or
      (d) change the Currency or Currencies in which the principal of (and

      maintain a paying agency outside the United States for payment on Bearer

      to convert any Debt Security into shares of Common Stock of the Company as
      may be provided pursuant to Section 3.1;

            (3) reduce the percentage in principal amount of the Outstanding
      Debt Securities of any series, the consent of whose Holders is required
      for any 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

            (4) modify any of the provisions of this Section, Section 5.13 or
      Section 12.7, 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 of
      each series 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 12.7, or the deletion of this proviso, in accordance with the
      requirements of Sections 6.10 and 11.1(9).

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

      A supplemental indenture which changes or eliminates any covenant or other
provision of this Indenture with respect to one or more particular series of
Debt Securities and Coupons, if any, or which modifies the rights of the Holders
of Debt Securities and Coupons 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 and Coupons, if any, of any other series.

      SECTION 11.3. EXECUTION OF SUPPLEMENTAL INDENTURES.

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

is authorized or permitted by this Indenture and that the supplemental indenture
conforms to the requirements of the Trust Indenture Act as then in effect. The
Trustee may, but shall not be obligated to, enter into any such supplemental

Board of Directors, 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 and Coupons of such series.

respect thereof, as provided in the terms and conditions of such Debt Security,
shall be payable only upon presentation of such Debt Security to the Trustee for
notation thereon of the payment of such interest.

      Unless otherwise specifically provided for with respect to any series of
Debt Securities under Section 3.1, the Company will deliver to the Trustee, on

<PAGE>

officer, principal financial officer or principal accounting officer of the
Company stating whether or not to the best knowledge of the signer thereof the
Company is in compliance with all covenants and conditions under this Indenture,
and, if the Company shall be in default, specifying all such defaults and the
nature thereof of which such signer may have knowledge. For purposes of this
Section, such compliance shall be determined without regard to any period of
grace or requirement of notice provided under this Indenture.

      SECTION 12.3. MAINTENANCE OF OFFICE OR AGENCY.

      If Debt Securities of a series are issuable only as Registered Securities,
the Company will maintain in each Place of Payment for such series an office or
agency where Debt Securities of that series may be presented or surrendered for
payment, where Debt Securities of that series may be surrendered for
registration of transfer or exchange, where Debt Securities of that series that
are convertible may be surrendered for conversion, if applicable, and where
notices and demands to or upon the Company in respect of the Debt Securities of
that series and this Indenture may be served. If Debt Securities of a series are
issuable as Bearer Securities, the Company will maintain (A) in the Borough of
Manhattan, The City and State of New York, an office or agency where any
Registered Securities of that series may be presented or surrendered for
payment, where any Registered Securities of that series may be surrendered for
registration of transfer, where Debt Securities of that series may be
surrendered for exchange or redemption, where notices and demands to or upon the
Company in respect of the Debt Securities of that series and this Indenture may
be served and where Bearer Securities of that series and related Coupons may be
presented or surrendered for payment in the circumstances described in the
following paragraph (and not otherwise), (B) subject to any laws or regulations
applicable thereto, in a Place of Payment for that series which is located
outside the United States, an office or agency where Debt Securities of that
series and related Coupons may be presented and surrendered for payment
(including payment of any additional amounts payable on Debt Securities of that
series, if so provided pursuant to Section 3.1); provided, however, that if the
Debt Securities of that series are listed on The Stock Exchange of the United
Kingdom and the Republic of Ireland, the Luxembourg Stock Exchange or any other
stock exchange located outside the United States and such stock exchange shall
so require, the Company will maintain a Paying Agent for the Debt Securities of
that series in London, Luxembourg or any other required city located outside the
United States, as the case may be, so long as the Debt Securities of that series
are listed on such exchange, and (C) subject to any laws or regulations
applicable thereto, in a Place of Payment for that series located outside the
United States an office or agency where any Registered Securities of that series
may be surrendered for registration of transfer, where Debt Securities of that
series may be surrendered for exchange or redemption and where notices and
demands to or upon the Company in respect of the Debt Securities of that series
and this Indenture may be served. The Company will give prompt written notice to
the Trustee of the location, and any change in the location, of such office or
agency.

      No payment of principal, premium or interest on Bearer Securities shall be
made at any office or agency of the Company in the United States or by check
mailed to any address in the United States or by transfer to an account
maintained with a bank located in the United States; provided, however, that, if
the Debt Securities of a series are denominated and payable in Dollars, payment
of principal of and any premium and interest on any Bearer Security (including
any additional amounts payable on Securities of such series, if so provided
pursuant to Section

                                       82
<PAGE>

3.1) shall be made at the office of the Company's Paying Agent in the Borough of
Manhattan, The City and State of New York, if (but only if) payment in Dollars
of the full amount of such principal, premium, interest or additional amounts,
as the case may be, at all offices or agencies 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.

      The Company may also from time to time designate different or additional
offices or agencies to be maintained for such purposes (in or outside of such
Place of Payment), and may from time to time rescind any such designations;
provided, however, that no such designation or rescission shall in any manner
relieve the Company of its obligations described in the preceding paragraph. The
Company will give prompt written notice to the Trustee of any such additional
designation or rescission of designation and any change in the location of any
such different or additional office or agency.

      SECTION 12.4. 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 and Coupons, if any, 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 and Coupons, it will, by 10:00 a.m. (New York City
time) or on each due date of the principal (and premium, if any) or interest on
any Debt Securities of such series, deposit with any such 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
thereto, and (unless any such Paying Agent is the Trustee) the Company will
promptly notify the Trustee of its action or failure so to act.

      Notwithstanding any term herein to the contrary, in no instance shall the
Trustee be under any duty or obligation (i) to maintain any office or to act in
any capacity as an agent for any purpose under this Indenture (or any supplement
hereto) outside the United States, or (ii) to act as a Paying Agent in respect
of any currency other than Dollars.

      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;

                                       83
<PAGE>

            (2) give the Trustee notice of any default by the Company (or any
      other obligor upon the Debt Securities of such series) in the making of
      any payment of principal (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 obtaining the satisfaction
and discharge of this Indenture or for any other purpose, pay, or by Company
Order direct any Paying Agent to pay, to the Trustee all sums held in trust by
the Company or such Paying Agent, such sums to be held by the Trustee upon the
same trusts as those upon which such sums were held by the Company or such
Paying Agent; and, upon such payment by any Paying Agent to the Trustee, such
Paying Agent shall be released from all further liability with respect to such
money.

      Any money deposited with the Trustee or any Paying Agent, or then held by
the Company, in trust for the payment of the principal of (and premium, if any)
or interest on any Debt Security of any series 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 upon Company Request, or (if then held by
the Company) shall be discharged from such trust; and the Holder of such Debt
Security or Coupon shall thereafter, as an unsecured general creditor, look only
to the Company for payment thereof, and all liability of the Trustee or such
Paying Agent with respect to such trust money, and all liability of the Company
as trustee thereof, shall thereupon cease; provided, however, that the Trustee
or such Paying Agent, before being required to make any such repayment, may at
the expense of the Company cause to be transmitted in the manner and to the
extent provided by Section 1.5, 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 notification, any unclaimed balance of such money then
remaining will be repaid to the Company.

      SECTION 12.5. CORPORATE EXISTENCE.

      Subject to Article X, 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
Company shall determine that the preservation thereof is no longer desirable in
the conduct of the business of the Company.

      SECTION 12.6. PURCHASE OF DEBT SECURITIES BY COMPANY.

      If the Debt Securities of a series are listed on The Stock Exchange of the
United Kingdom and the Republic of Ireland and such stock exchange shall so
require, the Company will not purchase any Debt Securities of that series by
private treaty at a price (exclusive of expenses and accrued interest) which
exceeds 120% of the mean of the nominal quotations of the

                                       84
<PAGE>

Debt Securities of that series as shown in The Stock Exchange Daily Official
List for the last trading day preceding the date of purchase.

      SECTION 12.7. WAIVER OF CERTAIN COVENANTS.

      The Company may omit in any particular instance to comply with any term,
provision or condition set forth in Sections 12.5 and 12.6 (and, if so specified
pursuant to Section 3.1, any other covenant not set forth herein and specified
pursuant to Section 3.1 to be applicable to the Securities of any series, except
as otherwise provided pursuant to Section 3.1) 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 Outstanding Debt Securities of
such series shall, by Act of such Holders, either waive such compliance in such
instance or generally waive compliance with such term, provision or condition,
but no such waiver shall extend to or affect such term, provision or condition
except to the extent expressly so waived, and, until such waiver shall become
effective, the obligations of the Company and the duties of the Trustee in
respect of any such term, provision or condition shall remain in full force and
effect.

                                 ARTICLE XIII.

                         REDEMPTION OF DEBT SECURITIES

      SECTION 13.1. APPLICABILITY OF ARTICLE.

      Debt Securities of any series which are redeemable before their Maturity
shall be redeemable in accordance with their terms and (except as otherwise
specified pursuant to Section 3.1 for Debt Securities of any series) in
accordance with this Article XIII.

      SECTION 13.2. ELECTION TO REDEEM; NOTICE TO TRUSTEE.

      The election of the Company to redeem (or, in the case of Discount
Securities, to permit the Holders to elect to surrender for redemption) 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 pursuant to Section 13.3, the Company shall, at least 30 days before the
Redemption Date fixed by the Company (unless a shorter notice shall be
satisfactory to the Trustee), notify the Trustee of such Redemption Date and of
the principal amount of Debt Securities of such 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 restrictions.

      SECTION 13.3. SELECTION BY TRUSTEE OF DEBT SECURITIES TO BE REDEEMED.

      Except in the case of a redemption in whole of the Bearer Securities or
the Registered Securities of such series, if less than all the Debt Securities
of any series are to be redeemed at the election of the Company, 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 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

                                       85
<PAGE>

portions (equal to the minimum authorized denomination for Debt Securities of
such series or any integral multiple thereof) of the principal amount of Debt
Securities of such series in a denomination larger than the minimum authorized
denomination for Debt Securities of such series pursuant to Section 3.2 in the
Currency in which the Debt Securities of such series are denominated. The
portions of the principal amount of Debt Securities so selected for partial
redemption shall be equal to the minimum authorized denominations for Debt
Securities of such series pursuant to Section 3.2 in the Currency in which the
Debt Securities of such series are denominated or any integral multiple thereof,
except as otherwise set forth in the applicable form of Debt Securities. In any
case when more than one Registered Security of such series is registered in the
same name, the Trustee in its discretion may treat the aggregate principal
amount so registered as if it were represented by one Registered Security of
such series.

      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 13.4. NOTICE OF REDEMPTION.

      Notice of redemption 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, not less
than 30 days and not more than 60 days prior to the Redemption Date to the
Holders of Debt Securities of any series to be redeemed in whole or in part
pursuant to this Article XIII, in the manner provided in Section 1.5. Any notice
so given shall be conclusively presumed to have been duly given, whether or not
the Holder receives such notice. Failure to give such notice, or any defect in
such notice to the Holder of any Debt Security of a series designated for
redemption, in whole or in part, shall not affect the sufficiency of any notice
of redemption with respect to the Holder of any other Debt Security of such
series.

      All notices of redemption shall state:

            (1) the Redemption Date;

            (2) the Redemption Price;

            (3) that Debt Securities of such series are being redeemed by the
      Company pursuant to provisions contained in this Indenture or the terms of
      the Debt Securities of such series or a supplemental indenture
      establishing such series, if such be the case, together with a brief
      statement of the facts permitting such redemption;

            (4) 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;

                                       86
<PAGE>

            (5) 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, if any, shall cease to accrue on and after said date;

            (6) that, unless otherwise specified in such notice, Coupon
      Securities of any series, if any, surrendered for redemption must be
      accompanied by all Coupons maturing subsequent to the date fixed for
      redemption, failing which the amount of any such missing Coupon or Coupons
      will be deducted from the Redemption Price;

            (7) the Place or Places of Payment where such Debt Securities are to
      be surrendered for payment of the Redemption Price;

            (8) if Bearer Securities of any series are to be redeemed and any
      Registered Securities of such series are not to be redeemed, and if such
      Bearer Securities may be exchanged for Registered Securities not subject
      to redemption on this Redemption Date pursuant to Section 3.5(b) or
      otherwise, the last date on which such exchanges may be made; and

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

      SECTION 13.5. DEPOSIT OF REDEMPTION PRICE.

      On or prior to 10:00 a.m. (New York City time) on the Redemption Date for
any Debt Securities, 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 12.4) an amount of money in the Currency or
Currencies in which such Debt Securities are denominated (except as provided
pursuant to Section 3.1) sufficient to pay the Redemption Price of such Debt
Securities or any portions thereof which are to be redeemed on that date.

      SECTION 13.6. DEBT SECURITIES PAYABLE ON REDEMPTION DATE.

      Notice of redemption having been given as aforesaid, any Debt Securities
so to be redeemed shall become due and payable on the Redemption Date, at the
Redemption Price in the Currency in which the Debt Securities of such series are
payable (except as otherwise specified pursuant to Section 3.1 or 3.10), and on
and after such date (unless the Company shall default in the payment of the
Redemption Price) such Debt Securities shall cease to bear interest. 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;
provided, however, that installments of interest on Bearer Securities whose
Stated Maturity is on or prior to the Redemption Date shall be payable only at
an office or agency located outside the United States (except as otherwise
provided in Section 12.3) and, unless otherwise specified as contemplated by
Section 3.1, only upon presentation and surrender of Coupons for such interest;
and provided, further, that, unless otherwise specified as contemplated by
Section 3.1, installments of interest on Registered Securities which have a
Stated Maturity on or prior to the Redemption Date for such Debt Securities
shall be payable according to the terms of such Debt Securities and the
provisions of Section 3.7.

                                       87
<PAGE>

      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.

      If any Coupon Security surrendered for redemption shall not be accompanied
by all Coupons appertaining thereto maturing on or after the Redemption Date,
the Redemption Price for such Coupon Security may be reduced by an amount equal
to the face amount of all such missing Coupons. If thereafter the Holder of such
Coupon shall surrender to any Paying Agent outside the United States 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. 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.

      SECTION 13.7. DEBT SECURITIES REDEEMED IN PART.

      Any Debt Security which is to be redeemed only in part shall be
surrendered at the Corporate Trust Office or such other office or agency of the
Company as is specified pursuant to Section 3.1 (in the case of Registered
Securities) and at an office of the Trustee, or at such other office or agency
of the Company outside the United States as is specified pursuant to Section 3.1
(in the case of Bearer Securities) with, if the Company, the Security Registrar
or the Trustee so requires, due endorsement by, or a written instrument of
transfer in form satisfactory to the Company, the Security Registrar and the
Trustee duly executed by, the Holder thereof or his attorney duly authorized in
writing, and the Company shall execute, and the Trustee shall authenticate and
deliver to the Holder of such Debt Security without service charge, a new Debt
Security or Debt Securities of the same series, of like tenor and form, of any
authorized denomination as requested by such Holder in aggregate principal
amount equal to and in exchange for the unredeemed portion of the principal of
the Debt Security so surrendered, and, in the case of a Coupon Security, with
appropriate Coupons attached. In the case of a Debt Security providing
appropriate space for such notation, at the option of the Holder thereof, the
Trustee, in lieu of delivering a new Debt Security or Debt Securities as
aforesaid, may make a notation on such Debt Security of the payment of the
redeemed portion thereof.

      SECTION 13.8. CONVERSION ARRANGEMENT IN CALL FOR REDEMPTION.

In connection with any redemption of Debt Securities of any series, the Company
may arrange for the purchase and conversion of any such Debt Securities by an
agreement with one or more investment bankers or other purchasers to purchase
such Debt Securities by paying to the Trustee or the Paying Agent in trust for
the Holders of such Debt Securities, on or before 10:00 a.m. New York time on
the Redemption Date, an amount not less than the Redemption Price, together with
interest, if any, accrued to the redemption date of such Debt Securities, in
immediately available funds. Notwithstanding anything to the contrary contained
in this Article XIII, the obligation of the Company to pay the Redemption Price
of such Debt Securities, including all accrued interest, if any, shall be deemed
to be satisfied and discharged to the extent such amount is so paid by such
purchasers. If such an agreement is entered into, any Debt Securities not duly
surrendered for conversion by the Holders thereof, at the option of the Company,
may be deemed, to the fullest extent permitted by law, acquired by such
purchasers from such Holders and surrendered

                                       88
<PAGE>

by such purchasers for conversion, all as of immediately prior to the close of
business on the last Business Day on which such Debt Securities called for
redemption may be converted in accordance with this Indenture and the terms of
such Debt Securities, subject to payment to the Trustee or Paying Agent of the
above-described amount. The Trustee or the Paying Agent shall hold and pay to
the Holders whose Debt Securities are selected for redemption any such amount
paid to it in the same manner as it would pay funds deposited with it by the
Company for the redemption of Debt Securities of such series. Without the
Trustee's and the Paying Agent's prior written consent, no arrangement between
the Company and such purchasers for the purchase and conversion of any
Securities shall increase or otherwise affect any of the powers, duties,
responsibilities or obligations of the Trustee and the Paying Agent as set forth
in this Indenture.

                                  ARTICLE XIV.

                                  SINKING FUNDS

      SECTION 14.1. APPLICABILITY OF ARTICLE.

      The provisions of this Article XIV shall be applicable to any sinking fund
for the retirement of Debt Securities of a series except as otherwise specified
pursuant to Section 3.1 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 as an "optional
sinking fund payment." If provided for by the terms of Debt Securities of any
series, the amount of any cash sinking fund payment may be subject to reduction
as provided in Section 14.2. 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 14.2. SATISFACTION OF MANDATORY SINKING FUND PAYMENTS WITH DEBT
SECURITIES.

      In lieu of making all or any part of a mandatory sinking fund payment with
respect to any Debt Securities of a series in cash, the Company may at its
option, at any time no more than sixteen months and no less than 45 days prior
to the date on which such sinking fund payment is due, deliver to the Trustee
Debt Securities of such series (together with the unmatured Coupons, if any,
appertaining thereto) theretofore purchased or otherwise acquired by the
Company, except Debt Securities of such series which have been redeemed through
the application of mandatory sinking fund payments pursuant to the terms of the
Debt Securities of such series, accompanied by a Company Order instructing the
Trustee to credit such obligations and stating that the Debt Securities of such
series were originally issued by the Company by way of bona fide sale or other
negotiation for value, provided that such Debt Securities shall not have 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 mandatory sinking fund payment shall be reduced accordingly.

                                       89
<PAGE>

      SECTION 14.3. REDEMPTION OF DEBT SECURITIES FOR SINKING FUND.

      Not less than 60 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 in the Currency or Currencies in which the Debt
Securities of such series are denominated (except as provided pursuant to
Section 3.1) and the portion thereof, if any, which is to be satisfied by
delivering and crediting Debt Securities of such series pursuant to Section 14.2
and whether the Company intends to exercise its rights to make a permitted
optional sinking fund payment with respect to such series. Such certificate
shall be irrevocable and upon its delivery the Company shall be obligated to
make the cash payment or payments therein referred to, if any, on or before the
next succeeding sinking fund payment date. In the case of the failure of the
Company to deliver such certificate, the sinking fund payment due on the next
succeeding sinking fund payment date for such series shall be paid entirely in
cash and shall be sufficient to redeem the principal amount of the Debt
Securities of such series subject to a mandatory sinking fund payment without
the right to deliver or credit Debt Securities as provided in Section 14.2 and
without the right to make any optional sinking fund payment with respect to such
series at such time.

      Any sinking fund payment or payments (mandatory or optional) made in cash
plus any unused balance of any preceding sinking fund payments made with respect
to the Debt Securities of any particular series shall be applied by the Trustee
(to the extent it is acting as a Paying Agent with respect to Dollars) or other
Paying Agent appointed by the Company (or by the Company if the Company is
acting as its own Paying Agent) on the sinking fund payment date on which such
payment is made (or, if such payment is made before a sinking fund payment date,
on the sinking fund payment date immediately following the date of such payment)
to the redemption of Debt Securities of such series at the Redemption Price
specified in such Debt Securities with respect to the sinking fund. Any sinking
fund moneys not so applied or allocated by the Trustee (to the extent it is
acting as a Paying Agent with respect to Dollars) or other Paying Agent
appointed by the Company (or by the Company if the Company is acting as its own
Paying Agent) to the redemption of Debt Securities shall be added to the next
sinking fund payment received by the Trustee (to the extent it is acting as a
Paying Agent with respect to Dollars) or other Paying Agent appointed by the
Company (or if the Company is acting as its own Paying Agent, segregated and
held in trust as provided in Section 12.4) for such series and, together with
such payment (or such amount so segregated) shall be applied in accordance with
the provisions of this Section. Any and all sinking fund moneys with respect to
the Debt Securities of any particular series held by the Trustee (to the extent
it is acting as a Paying Agent with respect to Dollars) or other Paying Agent
appointed by the Company (or if the Company is acting as its own Paying Agent,
segregated and held in trust as provided in Section 12.4) on the last sinking
fund payment date with respect to Debt Securities of such series and not held
for the payment or redemption of particular Debt Securities of such series shall
be applied by the Trustee (to the extent it is acting as a Paying Agent with
respect to Dollars) or other Paying Agent appointed by the Company (or by the
Company if the Company is acting as its own Paying Agent), together with other
moneys, if necessary, to be deposited (or segregated) sufficient for the
purpose, to the payment of the principal of the Debt Securities of such series
at Maturity.

                                       90
<PAGE>

      The Trustee shall select or cause to be selected the Debt Securities to be
redeemed upon such sinking fund payment date in the manner specified in Section
13.3 and the Company shall cause notice of the redemption thereof to be given in
the manner provided in Section 13.4. Such notice having been duly given, the
redemption of such Debt Securities shall be made upon the terms and in the
manner stated in Section 13.6.

      On or before 10:00 a.m. (New York City time) on each sinking fund payment
date, the Company shall pay to the Trustee (to the extent it is acting as a
Paying Agent with respect to Dollars) or other Paying Agent appointed by the
Company (or, if the Company is acting as its own Paying Agent, the Company shall
segregate and hold in trust as provided in Section 12.4) in cash a sum, in the
Currency or Currencies in which Debt Securities of such series are denominated
(except as provided pursuant to Sections 3.1 or 3.10), equal to the principal
and any interest accrued to the Redemption Date for Debt Securities or portions
thereof to be redeemed on such sinking fund payment date pursuant to this
Section.

      Neither the Trustee, any Paying Agent nor the Company shall redeem any
Debt Securities of a series with sinking fund moneys or mail any notice of
redemption of Debt Securities of such series by operation of the sinking fund
for such series during the continuance of a default in payment of interest, if
any, on any Debt Securities of such series or of any Event of Default (other
than an Event of Default occurring as a consequence of this paragraph) with
respect to the Debt Securities of such series, except that if the notice of
redemption shall have been provided in accordance with the provisions hereof,
the Trustee or applicable Paying Agent (or the Company, if the Company is then
acting as its own Paying Agent) shall redeem such Debt Securities if cash
sufficient for that purpose shall be deposited with the Trustee or such other
Paying Agent as provided above (or segregated by the Company) for that purpose
in accordance with the terms of this Article XIV. Except as aforesaid, any
moneys in the sinking fund for such series at the time when any such default or
Event of Default shall occur and any moneys thereafter paid into such sinking
fund shall, during the continuance of such default or Event of Default, be held
as security for the payment of the Debt Securities and Coupons, if any, of such
series; provided, however, that in case such default or Event of Default shall
have been cured or waived as provided herein, such moneys shall thereafter be
applied on or prior to the next sinking fund payment date for the Debt
Securities of such series on which such moneys may be applied pursuant to the
provisions of this Section.

                                  ARTICLE XV.

                                   DEFEASANCE

      SECTION 15.1. APPLICABILITY OF ARTICLE.

      If, pursuant to Section 3.1, provision is made for the defeasance of Debt
Securities of a series, and if the Debt Securities of such series are Registered
Securities and denominated and payable only in Dollars (except as provided
pursuant to Section 3.1 and subject to the proviso in the last sentence of this
paragraph) then the provisions of this Article XV shall be applicable except as
otherwise specified pursuant to Section 3.1 for Debt Securities of such series.
Defeasance provisions, if any, for Debt Securities denominated and/or payable in
a Foreign Currency or Currencies or for Bearer Securities may be specified
pursuant to Section 3.1;

                                       91
<PAGE>

provided, however, that nothing herein or therein shall obligate the Trustee
(without its consent, at its sole option) to hold or maintain any account, or
act as Paying Agent with respect to, any Foreign Currency or Currencies.

      SECTION 15.2. DEFEASANCE UPON DEPOSIT OF MONEYS OR U.S. GOVERNMENT
OBLIGATIONS.

      At the Company's option, either (a) the Company shall be deemed to have
been Discharged (as defined below) from its obligations with respect to Debt
Securities of any series ("legal defeasance option") or (b) the Company shall
cease to be under any obligation to comply with any term, provision or condition
set forth in Article X with respect to Debt Securities of any series (and, if so
specified pursuant to Section 3.1, any other obligation of the Company or
restrictive covenant added for the benefit of such series pursuant to Section
3.1) ("covenant defeasance option") at any time after the applicable conditions
set forth below have been satisfied:

            (1) the Company shall have deposited or caused to be deposited
      irrevocably with the Trustee as trust funds in trust, specifically pledged
      as security for, and dedicated solely to, the benefit of the Holders of
      the Debt Securities of such series (i) money in an amount, or (ii) U.S.
      Government Obligations (as defined below) which through the payment of
      interest and principal in respect thereof in accordance with their terms
      will provide, not later than one day before the due date of any payment,
      money in an amount, or (iii) a combination of (i) and (ii), sufficient, in
      the opinion (with respect to (i) and (ii)) of a nationally recognized firm
      of independent public accountants expressed in a written certification
      thereof delivered to the Trustee, to pay and discharge each installment of
      principal (including any mandatory sinking fund payments) of and premium,
      if any, and interest on, the Outstanding Debt Securities of such series on
      the dates such installments of interest or principal and premium are due;

            (2) such deposit shall not cause the Trustee with respect to the
      Debt Securities of that series to have a conflicting interest as defined
      in Section 6.8 and for purposes of the Trust Indenture Act with respect to
      the Debt Securities of any series;

            (3) such deposit will not result in a breach or violation 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) if the Debt Securities of such series are then listed on any
      national securities exchange, the Company shall have delivered to the
      Trustee an Opinion of Counsel or a letter or other document from such
      exchange to the effect that the Company's exercise of its option under
      this Section would not cause such Debt Securities to be delisted;

            (5) no Event of Default or event (including such deposit) which,
      with notice or lapse of time or both, would become an Event of Default
      with respect to the Debt Securities of such series shall have occurred and
      be continuing on the

                                       92
<PAGE>

      date of such deposit and, with respect to the legal defeasance option
      only, no Event of Default under Section 5.1(5) or Section 5.1(6) or event
      which with the giving of notice or lapse of time, or both, would become an
      Event of Default under Section 5.1(5) or Section 5.1(6) shall have
      occurred and be continuing on the 91st day after such date; and

            (6) the Company shall have delivered to the Trustee an Opinion of
      Counsel or a ruling from the Internal Revenue Service to the effect that
      the Holders of the Debt Securities of such series will not recognize
      income, gain or loss for Federal income tax purposes as a result of such
      deposit, defeasance or Discharge.

Notwithstanding the foregoing, if the Company exercises its covenant defeasance
option and an Event of Default under Section 5.1(5) or Section 5.1(6) or an
event which with the giving of notice or lapse of time, or both, would become an
Event of Default under Section 5.1(5) or Section 5.1(6) shall have occurred and
be continuing on the 91st day after the date of such deposit, the obligations of
the Company referred to under the definition of covenant defeasance option with
respect to such Debt Securities shall be reinstated.

Notwithstanding the Company's exercise of the covenant defeasance option, the
Company may subsequently exercise the legal defeasance option.

      "Discharged" means that the Company shall be deemed to have paid and
discharged the entire indebtedness represented by, and obligations under, the
Debt Securities of such series and to have satisfied all the obligations under
this Indenture relating to the Debt Securities of such series (and the Trustee
for such series of Debt Securities, at the expense of the Company, shall execute
proper instruments acknowledging the same), except (A) the rights of Holders of
Debt Securities of such series to receive, from the trust fund described in
clause (1) above, payment of the principal of (and premium, if any) and interest
on such Debt Securities when such payments are due, (B) the Company's
obligations with respect to the Debt Securities of such series under Sections
3.4, 3.5, 3.6, 12.3 and 15.3 and (C) the rights, powers, trusts, duties and
immunities of the Trustee hereunder.

      "U.S. Government Obligations" means securities that are (i) direct
obligations of the United States for the payment of which its full faith and
credit is pledged, or (ii) obligations of a Person controlled or supervised by
and acting as an agency or instrumentality of the United States the payment of
which is unconditionally guaranteed as a full faith and credit obligation by the
United States, which, in either case under clauses (i) or (ii), are not callable
or redeemable at the option of the issuer thereof, and shall also include a
depository receipt issued by a bank or trust company as custodian with respect
to any such U.S. Government Obligation or a specific payment of interest on or
principal of any such U.S. Government Obligation held by such custodian for the
account of the holder of a depository receipt; provided that (except as required
by law) such custodian is not authorized to make any deduction from the amount
payable to the holder of such depository receipt from any amount received by the
custodian in respect of

                                       93
<PAGE>

the U.S. Government Obligation or the specific payment of interest on or
principal of the U.S. Government Obligation evidenced by such depository
receipt.

      SECTION 15.3. DEPOSITED MONEYS AND U.S. GOVERNMENT OBLIGATIONS TO BE HELD
IN TRUST.

      All moneys and U.S. Government Obligations deposited with the Trustee
pursuant to Section 15.2 in respect of Debt Securities of a series shall be held
in trust and applied by it, in accordance with the provisions of such Debt
Securities and this Indenture, to the payment, either directly or through any
Paying Agent (including the Company acting as its own Paying Agent) as the
Trustee may determine, to the Holders of such Debt Securities, of all sums due
and to become due thereon for principal (and premium, if any) and interest, if
any, but such money need not be segregated from other funds except to the extent
required by law.

      SECTION 15.4. REPAYMENT TO COMPANY.

      The Trustee and any Paying Agent shall promptly pay or return to the
Company upon Company Request any moneys or U.S. Government Obligations held by
them at any time that are not required for the payment of the principal of (and
premium, if any) and interest on the Debt Securities of any series for which
money or U.S. Government Obligations have been deposited pursuant to Section
15.2.

      The provisions of the last paragraph of Section 12.4 shall apply to any
money held by the Trustee or any Paying Agent under this Article XV that remains
unclaimed for two years after the Maturity of any series of Debt Securities for
which money or U.S. Government Obligations have been deposited pursuant to
Section 15.2.

                                  ARTICLE XVI.

                                   CONVERSION

      SECTION 16.1. APPLICABILITY; CONVERSION PRIVILEGE.

      Except as otherwise specified pursuant to Section 3.1 for Debt Securities
of any series, the provisions of this Article XVI shall be applicable to any
Debt Securities that are convertible into Common Stock. If so provided pursuant
to Section 3.1 with respect to the Debt Securities of any series, the Holder of
a Debt Security of such series shall have the right, at such Holder's option, to
convert, in accordance with the terms of such series of Debt Securities and this
Article XVI, all or any part (in a denomination of, unless otherwise specified
pursuant to Section 3.1 with respect to Securities of such series, $1,000 in
principal amount or any integral multiple thereof) of such Debt Security into
shares of Common Stock or, as to any Debt Securities called for redemption, at
any time prior to the time and date fixed for such redemption (unless the
Company shall default in the payment of the Redemption Price, in which case such
right shall not terminate at such time and date).

      SECTION 16.2. CONVERSION PROCEDURE; CONVERSION PRICE; FRACTIONAL SHARES.

      (a) Each Debt Security to which this Article XVI is applicable shall be
convertible at the office of the Conversion Agent, and at such other place or
places, if any, specified pursuant to Section 3.1 with respect to the Debt
Securities of such series, into fully paid and nonassessable shares (calculated
to the nearest 1/100th of a share) of Common Stock. The Debt Securities will be
converted into shares of Common Stock at the Conversion Price therefor. No
payment or adjustment shall be made in respect of dividends on the Common Stock
or accrued interest on a converted Debt Security except as described in Section
16.9. The Company may, but shall not be required, in connection with any
conversion of Debt Securities, to issue a fraction of a share of Common Stock
and, if the Company shall determine not to issue any such fraction, the Company
shall, subject to Section 16.3(4), make a cash payment (calculated to the
nearest cent) equal to such fraction multiplied by the Closing Price of the
Common Stock on the last Trading Day prior to the date of conversion.

      (b) Before any Holder of a Debt Security shall be entitled to convert the
same into Common Stock, such Holder shall surrender such Debt Security duly
endorsed to the Company or in blank, or, in the case of Bearer Securities,
together with all unmatured Coupons and any matured Coupons in default attached
thereto, at the office of the Conversion Agent or at such other place or places,
if any, specified pursuant to Section 3.1 (in the case of Registered Securities)
and at an office of the Conversion Agent or at such other place or places, if
any, outside of the United States as is specified pursuant to Section 3.1 (in
the case of Bearer Securities), and shall give written notice to the Company at
said office or place that he elects to convert the same and shall state in
writing therein the principal amount of Debt Securities to be converted and the
name or names (with addresses) in which he wishes the certificate or
certificates for Common Stock to be issued; provided, however, that no Debt
Security or portion thereof shall be accepted for conversion unless the
principal amount of such Debt Security or such portion, when added to the
principal amount of all other Debt Securities or portions thereof then being
surrendered by the Holder thereof for conversion, exceeds the then effective
Conversion Price with respect thereto. 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 conversion may be effected if the Bearer Securities to
be surrendered for conversion are accompanied by payment in funds acceptable to
the Company in an amount equal to the face amount of such missing Coupon or
Coupons, or the surrender of such missing Coupon or Coupons may be waived by the
Company and the Trustee if there is furnished to them such security or indemnity
as they may require to save each of them and any Paying Agent harmless. If
thereafter the Holder of such Bearer Security shall surrender to any Paying
Agent any such missing Coupon in respect of which such a payment shall have been
made, such Holder shall be entitled to receive the amount of such payment;
provided, however that except as otherwise provided in Section 12.3, 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. If more
than one Debt Security shall be surrendered for conversion at one time by the
same Holder, the number of full shares of Common Stock which shall be
deliverable upon conversion shall be computed on the basis of the aggregate
principal amount of the Debt Securities (or specified portions thereof to the
extent permitted thereby) so surrendered. Subject to the next succeeding
sentence, the Company will, as soon as practicable thereafter, issue and deliver
at said office or place to such Holder of a Debt Security, or to his nominee or
nominees,

                                       95
<PAGE>

certificates for the number of full shares of Common Stock to which he shall be
entitled as aforesaid, together, subject to the last sentence of paragraph (a)
above, with cash in lieu of any fraction of a share to which he would otherwise
be entitled. The Company shall not be required to deliver certificates for
shares of Common Stock while the stock transfer books for such stock or the
Security Register are duly closed for any purpose, but certificates for shares
of Common Stock shall be issued and delivered as soon as practicable after the
opening of such books or Security Register. A Debt Security shall be deemed to
have been converted as of the close of business on the date of the surrender of
such Debt Security for conversion as provided above, and the Person or Persons
entitled to receive the Common Stock issuable upon such conversion shall be
treated for all purposes as the record Holder or Holders of such Common Stock as
of the close of business on such date. In case any Debt Security shall be
surrendered for partial conversion, the Company shall execute and the Trustee
shall authenticate and deliver to or upon the written order of the Holder of the
Debt Securities so surrendered, without charge to such Holder (subject to the
provisions of Section 16.8), a new Debt Security or Securities in authorized
denominations in an aggregate principal amount equal to the unconverted portion
of the surrendered Debt Security.

      SECTION 16.3. ADJUSTMENT OF CONVERSION PRICE FOR COMMON STOCK.

      The Conversion Price with respect to any Debt Security which is
convertible into Common Stock shall be adjusted from time to time as follows:

            (1) In case the Company shall, at any time or from time to time
      while any of such Debt Securities are outstanding, (i) pay a dividend in
      shares of its Common Stock to holders of Common Stock, (ii) combine its
      outstanding shares of Common Stock into a smaller number of shares of
      Common Stock, (iii) subdivide its outstanding shares of Common Stock into
      a greater number of shares of Common Stock or (iv) make a distribution in
      shares of Common Stock to holders of Common Stock, then the Conversion
      Price in effect immediately before such action shall be adjusted so that
      the Holders of such Debt Securities, upon conversion thereof into Common
      Stock immediately following such event, shall be entitled to receive the
      kind and amount of shares of capital stock of the Company which they would
      have owned or been entitled to receive upon or by reason of such event if
      such Debt Securities had been converted immediately before the record date
      (or, if no record date, the effective date) for such event. An adjustment
      made pursuant to this Section 16.3(1) shall become effective retroactively
      immediately after the record date in the case of a dividend or
      distribution and shall become effective retroactively immediately after
      the effective date in the case of a subdivision or combination. For the
      purposes of this Section 16.3(1), each Holder of Debt Securities shall be
      deemed to have failed to exercise any right to elect the kind or amount of
      securities receivable upon the payment of any such dividend, subdivision,
      combination or distribution (provided that if the kind or amount of
      securities receivable upon such dividend, subdivision, combination or
      distribution is not the same for each nonelecting share, then the kind and
      amount of securities or other property receivable upon such dividend,
      subdivision, combination or distribution for each nonelecting share

                                       96
<PAGE>

      shall be deemed to be the kind and amount so receivable per share by a
      plurality of the nonelecting shares).

            (2) In case the Company shall, at any time or from time to time
      while any of such Debt Securities are outstanding, issue rights or
      warrants to all holders of shares of its Common Stock entitling them (for
      a period expiring within 45 days after the record date for such issuance)
      to subscribe for or purchase shares of Common Stock (or securities
      convertible into shares of Common Stock) at a price per share less than
      the Current Market Price of the Common Stock at such record date (treating
      the price per share of the securities convertible into Common Stock as
      equal to (x) the sum of (i) the price for a unit of the security
      convertible into Common Stock and (ii) any additional consideration
      initially payable upon the conversion of such security into Common Stock
      divided by (y) the number of shares of Common Stock initially underlying
      such convertible security), the Conversion Price with respect to such Debt
      Securities shall be adjusted so that it shall equal the price determined
      by dividing the Conversion Price in effect immediately prior to the date
      of issuance of such rights or warrants by a fraction, the numerator of
      which shall be the number of shares of Common Stock outstanding on the
      date of issuance of such rights or warrants plus the number of additional
      shares of Common Stock offered for subscription or purchase (or into which
      the convertible securities so offered are initially convertible), and the
      denominator of which shall be the number of shares of Common Stock
      outstanding on the date of issuance of securities which the aggregate
      offering price of the total number of shares of securities so offered for
      subscription or purchase (or the aggregate purchase price of the
      convertible securities so offered plus the aggregate amount of any
      additional consideration initially payable upon conversion of such
      securities into Common Stock) would purchase at such Current Market Price
      of the Common Stock. Such adjustment shall become effective retroactively
      immediately after the record date for the determination of shareholders
      entitled to receive such rights or warrants.

            (3) In the case the Company shall, at any time or from time to time
      while any of such Debt Securities are outstanding, distribute to all
      holders of shares of its Common Stock (including any such distribution
      made in connection with a consolidation or merger in which the Company is
      the continuing corporation and the Common Stock is not changed or
      exchanged) cash, evidences of its indebtedness, securities or assets
      (excluding (i) regular periodic cash dividends in amounts, if any,
      determined from time to time by the Board of Directors, (ii) dividends
      payable in shares of Common Stock for which adjustment is made under
      Section 16.3(1) or (iii) rights or warrants to subscribe for or purchase
      securities of the Company (excluding those referred to in Section
      16.3(2))), then in each such case the Conversion Price with respect to
      such Debt Securities determined by dividing the Conversion Price in effect
      immediately prior to the date of such distribution by a fraction, the
      numerator of which shall be the Current Market Price of the Common Stock
      on the record date referred to below, and the denominator of which shall
      be such Current Market Price of the Common Stock less the then fair market
      value (as determined by the Board of

                                       97
<PAGE>

      Directors of the Company, whose determination shall be conclusive) of the
      portion of the cash or assets or evidences of indebtedness or securities
      so distributed or of such subscription rights or warrants applicable to
      one share of Common Stock (provided that such denominator shall never be
      less than 1.0); provided however, that no adjustment shall be made with
      respect to any distribution of rights to purchase securities of the
      Company if a Holder of Debt Securities would otherwise be entitled to
      receive such rights upon conversion at any time of such Debt Securities
      into Common Stock unless such rights are subsequently redeemed by the
      Company, in which case such redemption shall be treated for purposes of
      this section as a dividend on the Common Stock. Such adjustment shall
      become effective retroactively immediately after the record date for the
      determination of shareholders entitled to receive such distribution; and
      in the event that such distribution is not so made, the Conversion Price
      shall again be adjusted to the Conversion Price which would then be in
      effect if such record date had not been fixed.

            (4) The Company shall be entitled to make such additional
      adjustments in the Conversion Price, in addition to those required by
      subsections 16.3(1), 16.3(2), and 16.3(3), as shall be necessary in order
      that any dividend or distribution of Common Stock, any subdivision,
      reclassification or combination of shares of Common Stock or any issuance
      of rights or warrants referred to above shall not be taxable to the
      holders of Common Stock for United States Federal income tax purposes.

            (5) In any case in which this Section 16.3 shall require that any
      adjustment be made effective as of or retroactively immediately following
      a record date, the Company may elect to defer (but only for five (5)
      Trading Days following the filing of the statement referred to in Section
      16.5) issuing to the Holder of any Debt Securities converted after such
      record date the shares of Common Stock and other capital stock of the
      Company issuable upon such conversion over and above the shares of Common
      Stock and other capital stock of the Company issuable upon such conversion
      on the basis of the Conversion Price prior to adjustment; provided,
      however, that the Company shall deliver to such Holder a due bill or other
      appropriate instrument evidencing such Holder's right to receive such
      additional shares upon the occurrence of the event requiring such
      adjustment.

            (6) All calculations under this Section 16.3 shall be made to the
      nearest cent or one-hundredth of a share of security, with one-half cent
      and 0.005 of a share, respectively, being rounded upward. Notwithstanding
      any other provision of this Section 16.3, the Company shall not be
      required to make any adjustment of the Conversion Price unless such
      adjustment would require an increase or decrease of at least 1% of such
      price. Any lesser adjustment shall be carried forward and shall be made at
      the time of and together with the next subsequent adjustment which,
      together with any adjustment or adjustments so carried forward, shall
      amount to an increase or decrease of at least 1% in such

                                       98
<PAGE>

      price. Any adjustments under this Section 16.3 shall be made successively
      whenever an event requiring such an adjustment occurs.

            (7) In the event that at any time, as a result of an adjustment made
      pursuant to this Section 16.3, the Holder of any Debt Security thereafter
      surrendered for conversion shall become entitled to receive any shares of
      stock of the Company other than shares of Common Stock into which the Debt
      Securities originally were convertible, the Conversion Price of such other
      shares so receivable upon conversion of any such Debt Security shall be
      subject to adjustment from time to time in a manner and on terms as nearly
      equivalent as practicable to the provisions with respect to Common Stock
      contained in subparagraphs (1) through (6) of this Section 16.3, and the
      provisions of Sections 16.1, 16.2 and 16.4 through 16.9 with respect to
      the Common Stock shall apply on like or similar terms to any such other
      shares and the determination of the Board of Directors as to any such
      adjustment shall be conclusive.

            (8) No adjustment shall be made pursuant to this Section: (i) if the
      effect thereof would be to reduce the Conversion Price below the par value
      (if any) of the Common Stock or (ii) subject to 16.3(5) hereof, with
      respect to any Debt Security that is converted prior to the time such
      adjustment otherwise would be made.

      SECTION 16.4. CONSOLIDATION OR MERGER OF THE COMPANY.

      In case of either (a) any consolidation or merger to which the Company is
a party, other than a merger or consolidation in which the Company is the
surviving or continuing corporation and which does not result in a
reclassification of, or change (other than a change in par value or from par
value to no par value or from no par value to par value, as a result of a
subdivision or combination) in, outstanding shares of Common Stock or (b) any
sale or conveyance of all or substantially all of the property and assets of the
Company to another Person, then each Debt Security then outstanding shall be
convertible from and after such merger, consolidation, sale or conveyance of
property and assets into the kind and amount of shares of stock or other
securities and property (including cash) receivable upon such consolidation,
merger, sale or conveyance by a holder of the number of shares of Common Stock
into which such Debt Securities would have been converted immediately prior to
such consolidation, merger, sale or conveyance, subject to adjustments which
shall be as nearly equivalent as may be practicable to the adjustments provided
for in this Article XVI (and assuming such holder of Common Stock failed to
exercise his rights of election, if any, as to the kind or amount of securities,
cash or other property (including cash) receivable upon such consolidation,
merger, sale or conveyance (provided that, if the kind or amount of securities,
cash or other property (including cash) receivable upon such consolidation,
merger, sale or conveyance is not the same for each nonelecting share, then the
kind and amount of securities, cash or other property (including cash)
receivable upon such consolidation, merger, sale or conveyance for each
nonelecting share shall be deemed to be the kind and amount so receivable per
share by a plurality of the nonelecting shares or securities)). The Company
shall not enter into any of the transactions referred to in clause (a) or (b) of
the preceding sentence unless effective provision shall be made so as to give
effect to the provisions

                                       99
<PAGE>

set forth in this Section 16.4. The provisions of this Section 16.4 shall apply
similarly to successive consolidations, mergers, sales or conveyances.

      SECTION 16.5. NOTICE OF ADJUSTMENT.

      Whenever an adjustment in the Conversion Price with respect to a series of
Debt Securities is required:

            (1) the Company shall forthwith place on file with the Trustee and
      any Conversion Agent for such Securities a certificate of the Treasurer or
      Chief Financial Officer of the Company, stating the adjusted Conversion
      Price determined as provided herein and setting forth in reasonable detail
      such facts as shall be necessary to show the reason for and the manner of
      computing such adjustment, such certificate to be conclusive evidence that
      the adjustment is correct; and

            (2) a notice stating that the Conversion Price has been adjusted and
      setting forth the adjusted Conversion Price shall forthwith be given by
      the Company, or at the Company's request, by the Trustee in the name and
      at the expense of the Company, in the manner provided in Section 1.5. Any
      notice so given shall be conclusively presumed to have been duly given,
      whether or not the Holder receives such notice.

      SECTION 16.6. NOTICE IN CERTAIN EVENTS.

      In case:

            (1) of a consolidation or merger to which the Company is a party and
      for which approval of any shareholders of the Company is required, or of
      the sale or conveyance to another Person or entity or group of Persons or
      entities acting in concert as a partnership, limited partnership,
      syndicate or other group (within the meaning of Rule 13d-3 under the
      Securities Exchange Act of 1934, as amended) of all or substantially all
      of the property and assets of the Company; or

            (2) of the voluntary or involuntary dissolution, liquidation or
      winding up of the Company; or

            (3) of any action triggering an adjustment of the Conversion Price
      pursuant to this Article XVI,

then, in each case, the Company shall cause to be filed with the Trustee and the
Conversion Agent for the applicable Debt Securities, and shall cause to be
given, to the Holders of record of applicable Debt Securities in the manner
provided in Section 1.5, at least fifteen (15) days prior to the applicable date
hereinafter specified, a notice stating (x) the date on which a record is to be
taken for the purpose of any distribution or grant of rights or warrants
triggering an adjustment to the Conversion Price pursuant to this Article XVI,
or, if a record is not to be taken, the date as of which the holders of record
or Common Stock entitled to such distribution, rights or warrants are to be
determined, or (y) the date on which any reclassification, consolidation,
merger, sale,

                                      100
<PAGE>

conveyance, dissolution, liquidation or winding up triggering an adjustment to
the Conversion Price pursuant to this Article XVI is expected to become
effective, and the date as of which it is expected that holders of Common Stock
of record shall be entitled to exchange their Common Stock for securities or
other property deliverable upon such reclassification, consolidation, merger,
sale, conveyance, dissolution, liquidation or winding up.

      Failure to give such notice or any defect therein shall not affect the
legality or validity of the proceedings described in clause (1), (2) or (3) of
this Section 16.6.

      SECTION 16.7. COMPANY TO RESERVE STOCK; REGISTRATION; LISTING.

      (a) The Company shall at all times reserve and keep available, free from
preemptive rights, out of its authorized but unissued shares of Common Stock,
for the purpose of effecting the conversion of the Debt Securities, such number
of its duly authorized shares of Common Stock as shall from time to time be
sufficient to effect the conversion of all applicable outstanding Debt
Securities into such Common Stock at any time (assuming that, at the time of the
computation of such number of shares or securities, all such Debt Securities
would be held by a single holder); provided, however, that nothing contained
herein shall preclude the Company from satisfying its obligations in respect of
the conversion of the Debt Securities by delivery of purchased shares of Common
Stock which are held in the treasury of the Company. The Company shall from time
to time, in accordance with the laws of the State of Missouri, use its best
efforts to cause the authorized amount of the Common Stock to be increased if
the aggregate of the authorized amount of the Common Stock remaining unissued
and the issued shares of such Common Stock in its treasury (other than any such
shares reserved for issuance in any other connection) shall not be sufficient to
permit the conversion of all Debt Securities.

      (b) If any shares of Common Stock which would be issuable upon conversion
of Debt Securities hereunder require registration with or approval of any
governmental authority before such shares or securities may be issued upon such
conversion, the Company will in good faith and as expeditiously as possible
endeavor to cause such shares or securities to be duly registered or approved,
as the case may be. The Company will endeavor to list the shares of Common Stock
required to be delivered upon conversion of the Debt Securities prior to such
delivery upon the principal national securities exchange upon which the
outstanding Common Stock is listed at the time of such delivery.

      SECTION 16.8. TAXES ON CONVERSION.

      The Company shall pay any and all documentary, stamp or similar issue or
transfer taxes that may be payable in respect of the issue or delivery of shares
of Common Stock on conversion of Debt Securities pursuant hereto. The Company
shall not, however, be required to pay any such tax which may be payable in
respect of any transfer involved in the issue or delivery of shares of Common
Stock or the portion, if any, of the Debt Securities which are not so converted
in a name other than that in which the Debt Securities so converted were
registered (in case of Registered Securities), and no such issue or delivery
shall be made unless and until the Person requesting such issue has paid to the
Company the amount of such tax or has established to the satisfaction of the
Company that such tax has been paid.

                                      101
<PAGE>

      SECTION 16.9. CONVERSION AFTER RECORD DATE.

      If any Debt Securities are surrendered for conversion subsequent to the
record date preceding an Interest Payment Date but on or prior to such Interest
Payment Date (except Debt Securities called for redemption on a Redemption Date
between such record date and Interest Payment Date), the Holder of such Debt
Securities at the close of business on such record date shall be entitled to
receive the interest payable on such Debt Securities on such Interest Payment
Date notwithstanding the conversion thereof. Debt Securities surrendered for
conversion during the period from the close of business on any record date next
preceding any Interest Payment Date to the opening of business on such Interest
Payment Date shall (except in the case of Debt Securities which have been called
for redemption on a Redemption Date within such period) be accompanied by
payment in New York Clearing House funds or other funds and in the Currency
acceptable to the Company of an amount equal to the interest payable on such
Interest Payment Date on the Debt Securities being surrendered for conversion.
Except as provided in this Section 16.9, no adjustments in respect of payments
of interest on Debt Securities surrendered for conversion or any dividends or
distributions of interest on the Common Stock issued upon conversion shall be
made upon the conversion of any Debt Securities.

      SECTION 16.10. CONVERSION OF DEBT SECURITIES INTO PREFERRED SHARES OR
OTHER SECURITIES.

      Notwithstanding anything to the contrary in this Article XVI, the Company
may issue Securities that are convertible into Preferred Stock or other
securities of the Company, including Preferred Shares convertible into Common
Stock, in which case all terms and conditions relating to the conversion of
Securities into Preferred Shares or other securities, including any terms
similar to those provided in Sections 16.01 through 16.12, shall be as provided
in or pursuant to an appropriate Board Resolution or in any indenture
supplemental hereto or as otherwise contemplated by Section 3.1.

      SECTION 16.11. COMPANY DETERMINATION FINAL.

      Any determination that the Company or the Board of Directors must make
pursuant to this Article XVI is conclusive.

      SECTION 16.12. TRUSTEE'S DISCLAIMER.

      The Trustee has no duty to determine when an adjustment under this Article
XVI should be made, how it should be made or what it should be. The Trustee
makes no representation as to the validity or value of any securities or assets
issued upon conversion of Debt Securities. The Trustee shall not be responsible
for the Company's failure to comply with this Article XVI. Each Conversion Agent
other than the Company shall have the same protection under this Section as the
Trustee.

      to it at the address of its principal office specified in the first

<PAGE>

addresses appear in the Security Register, within the time prescribed, and (2)
such notice shall be sufficiently given to Holders of Bearer Securities or
Coupons (unless otherwise herein expressly provided) if published at least twice
in an Authorized Newspaper or Newspapers in The City of New York and, if Debt
Securities of such series are then listed on The Stock Exchange of the United
Kingdom and the Republic of Ireland or the Luxembourg Stock Exchange or any
other stock exchange located outside the United States and such stock exchange
shall so require, in a daily newspaper in London or Luxembourg or in such other
city or cities specified pursuant to Section 3.1 or in any Debt Security on

to Holders of Floating Rate Securities regarding the determination of a periodic
rate of interest, if such notice is required pursuant to Section 3.1, shall be
sufficiently given if given in the manner specified pursuant to Section 3.1.

      In the event of suspension of regular mail service or by reason of any
other cause it shall be impracticable to give notice by mail, such notification
as the Company shall reasonably determine be given with the approval of the
Trustee shall constitute sufficient notice for every purpose hereunder.

      In the event of suspension of publication of any Authorized Newspapers or

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 on such waiver. In any case where notice to Holders is given by mail,
neither the failure to mail such notice nor any defect in any notice so mailed
to any particular Holder shall affect the sufficiency of such notice with
respect to other Holders, and any notice which is mailed in the manner herein
provided shall be conclusively presumed to have been duly given. In any case
where notice to Holders is given by publication, any defect in any notice so
published as to any particular Holder shall not affect the sufficiency of such
notice with respect to other Holders, and any notice which is published in the
manner herein provided shall be conclusively presumed to have been duly given.

Place of Payment for the Debt Securities of that series, then (notwithstanding

Securities represented thereby shall be made by the Trustee and in such manner
as shall be specified in such Global Note. Any instructions by the Company with
respect to a Global Note, after its initial issuance, shall be in writing but
need not comply with Section 1.2 and need not be accompanied by an Opinion of
Counsel.

      Global Notes may be issued in either registered or bearer form and in
either temporary or permanent form. Permanent Global Notes will be issued in
definitive form.

                               THE DEBT SECURITIES

      The aggregate principal amount of Debt Securities which may be
authenticated and delivered under this Indenture is unlimited.

      The Debt Securities may be issued in one or more series. There shall be
established in or pursuant to a Board Resolution and (subject to Section 3.3)

      distinguish the Debt Securities of such series from all other series of
      Debt Securities);

            (2) the aggregate principal amount of such series of Debt Securities
      and any limit, on the aggregate principal amount of the Debt Securities of
      the series which may be authenticated and delivered under this Indenture
      (except for Debt Securities authenticated and delivered upon transfer of,
      or in exchange for, or in lieu of, other Debt Securities of such series
      pursuant to Sections 3.4, 3.5, 3.6, 11.6 or 13.7);

      Securities of the series may be issued, and the date or dates or the
      method by which such date or dates will be determined, on which the

      are or may be payable (which, if so provided in such Board Resolution or
      supplemental indenture, may be determined by the Company from time to time
      as set forth in the Debt Securities of the series issued from time to
      time);

            (5) the rate or rates (which may be variable or fixed) at which the
      Debt Securities of the series shall bear interest, if any, or the method
      by which such rate or rates shall be determined, the date or dates from
      which such interest, if any, shall accrue or the method by which such date
      or dates shall be determined (which, in either case or both, if so
      provided in such Board Resolution or supplemental indenture, may be
      determined by the Company from time to time and set forth in the Debt
      Securities of the series issued from time to time); and the Interest
      Payment Dates on which such interest shall be payable (or the method of
      determination thereof), subject to the right, if any such right is
      provided pursuant to this Section 3.1, of the Company to defer or extend
      an Interest Payment Date

                                       18

      and the duration of such extension or deferral (an "Extended Interest
      Period"), and the Regular Record Dates, if any, for the interest payable
      on such Interest Payment Dates and the notice, if any, to Holders
      regarding the determination of interest, the manner of giving such notice,

      360-day year of twelve 30 day months and any conditions or contingencies
      as to the payment of interest in cash or otherwise, if any;

            (6) the place or places, if any, in addition to or instead of the
      Corporate Trust Office of the Trustee (in the case of Registered
      Securities) where the principal of (and premium, if any) and interest on
      Debt Securities of the series shall be payable; the extent to which, or

      in Section 3.7; the extent, if any, to which the provisions of the last
      sentence of Section 12.1 shall apply to the Debt Securities of the series;

      whether any Global Note will require any notation to evidence payment of
      principal or interest;

            (7) the obligation, if any, of the Company to redeem, repay,
      purchase or offer to purchase Debt Securities of the series pursuant to
      any mandatory redemption, sinking fund or analogous provisions or upon
      other conditions or at the option of the Holder thereof and the period or
      periods within which or the dates on which, the prices at which and the

      the circumstances under which and the place or places at which any such
      exchanges, if permitted, may be made;

            (13) whether provisions for payment of additional amounts or tax
      redemptions shall apply and, if such provisions shall apply, such
      provisions; and, if Bearer Securities of the series are to be issued,
      whether a procedure other than that set forth in Section 3.4(b) shall
      apply and, if so, such other procedure, and if the procedure set forth in
      Section 3.4(b) shall apply, the forms of certifications to be delivered
      under such procedure;

            (14) if other than Dollars, the Foreign Currency or Currencies in
      which Debt Securities of the series shall be denominated or in which
      payment of the principal of (and premium, if any) and interest on the Debt
      Securities of the series may be made, and the particular provisions

      without limitation, Article XVII;

            (23) if Bearer Securities of the series are to be issued, (x)
      whether interest in respect of any portion of a temporary Debt Security in
      global form (representing all of the Outstanding Bearer Securities of the
      series) payable in respect of any Interest Payment Date prior to the
      exchange of such temporary Debt Security for definitive Debt Securities of

      event, the terms and conditions (including any certification requirements)
      upon which any such interest payment received by a clearing organization

      including any adjustments thereto;

      inconsistent with the provisions of this Indenture).

      All Debt Securities of any one series shall be substantially identical
except as to denomination, rate of interest, Stated Maturity and the date from
which interest, if any, shall accrue, which, as set forth above, may be
determined by the Company from time to time as to Debt Securities of a series if
so provided in or established pursuant to the authority granted in a Board
Resolution or in any such indenture supplemental hereto, and except as may
otherwise be provided in or pursuant to such Board Resolution and (subject to
Section 3.3) set forth in such Officers' Certificate, or in any such indenture
supplemental hereto. All Debt Securities of any one series need not be issued at
the same time, and unless otherwise provided, a series may be reopened, without
the consent of the Holders, for issuance of additional Debt Securities of such
series or to establish additional terms of such series of Debt Securities, which
additional terms shall only be applicable to unissued or additional Debt
Securities of such series.

      If any of the terms of a series of Debt Securities is established in or
pursuant to a Board Resolution, a copy of such Board Resolution shall be
certified by the Secretary or an Assistant Secretary of the Company and
delivered to the Trustee at or prior to the delivery of the Officers'
Certificate setting forth the terms of the series.

      SECTION 3.2. DENOMINATIONS.

      In the absence of any specification pursuant to Section 3.1 with respect
to the Debt Securities of any series, the Debt Securities of such series shall
be issuable only as Registered Securities in denominations of $1,000 and any
integral multiple thereof and shall be payable only in Dollars.

                                       22
<PAGE>

      SECTION 3.3. EXECUTION, AUTHENTICATION; DELIVERY AND DATING.

      The Debt Securities and the Coupons, if any, of any series shall be
executed on behalf of the Company by its Chairman of the Board, a Vice Chairman,
its President, one of its Vice Presidents or its Treasurer. The signature of any
of these officers may be manual or facsimile.

      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 and Coupons or did not hold such offices at the date of such Debt
Securities and Coupons.

      At any time and from time to time after the execution and delivery of this
Indenture, the Company may deliver Debt Securities, with appropriate Coupons, if
any, of any series, executed by the Company, to the Trustee for authentication,
together with a Company Order for the authentication and delivery of such Debt
Securities and Coupons and the Trustee in accordance with the Company Order
shall authenticate and deliver such Debt Securities and Coupons; provided,
however, that, in connection with its sale during the "restricted period" (as
defined in Section 1.163-5(c)(2)(i)(D)(7) of the United States Treasury
Regulations), no Bearer Security shall be mailed or otherwise delivered to any
location in the United States; and provided, further, that a Bearer Security
(other than a temporary Global Note in bearer form) may be delivered outside the
United States in connection with its original issuance only if the Person
entitled to receive such Bearer Security shall have furnished to the Euro-clear
operator or to CEDEL a certificate substantially in the form set forth in
Exhibit A to this Indenture. If all the Debt Securities of any one series are
not to be issued at one time and if a Board Resolution or supplemental indenture
relating to such series shall so permit, such Company Order may set forth
procedures acceptable to the Trustee for the issuance of such Debt Securities
such as interest rate, Stated Maturity, date of issuance and date from which
interest, if any, shall accrue. If any Debt Security shall be represented by a
Permanent Global Note, then, for purposes of this Section 3.3 and Section 3.4,
the notation of a beneficial owner's interest therein upon original issuance of
such Debt Security or upon exchange of a portion of a temporary Global Note
shall be deemed to be delivery in connection with the original issuance of such
beneficial owner's interest in such Permanent Global Note. Except as permitted
by Section 3.6 or 3.7, the Trustee shall not authenticate and deliver any Bearer
Security unless all Coupons for interest then matured have been detached and
canceled.

      The Trustee shall be entitled to receive, and (subject to Section 6.1)
shall be fully protected in relying upon, prior to the authentication and
delivery of the Debt Securities and Coupons of such series, (i) the supplemental
indenture or the Board Resolution by or pursuant to which the form and terms of
such Debt Securities and Coupons have been approved and (ii) an Opinion of
Counsel substantially to the effect that:

            (1) the authentication order furnished by the Company to the Trustee
      in connection with the authentication and delivery of such Debt Securities
      and Coupons conforms to the requirements of this Indenture and constitutes
      sufficient authority hereunder for the Trustee to authenticate and deliver
      such Debt Securities and Coupons;

                                       23
<PAGE>

            (2) the forms and terms of such Debt Securities and Coupons are
      consistent with the provisions of this Indenture;

            (3) in the event that the forms or terms of such Debt Securities and
      Coupons have been established in a supplemental indenture, the execution
      and delivery of such supplemental indenture has been duly authorized by
      all necessary corporate action of the Company, such supplemental indenture
      has been duly executed and delivered by the Company and, assuming due
      authorization, execution and delivery by the Trustee, is a valid and
      binding obligation enforceable against the Company in accordance with its
      terms, subject to applicable bankruptcy, insolvency and similar laws
      affecting creditors' rights generally and subject, as to enforceability,
      to general principles of equity (regardless of whether enforcement is
      sought in a proceeding in equity or at law);

            (4) the execution and delivery of such Debt Securities and Coupons
      have been duly authorized by all necessary corporate action of the Company
      and such Debt Securities and Coupons have been duly executed by the
      Company and, assuming due authentication by the Trustee and delivery by
      the Company, are valid and binding obligations enforceable against the
      Company in accordance with their terms, entitled to the benefit of the
      Indenture, subject to applicable bankruptcy, insolvency and similar laws
      affecting creditors' rights generally and subject, as to enforceability,
      to general principles of equity (regardless of whether enforcement is
      sought in a proceeding in equity or at law) and subject to such other
      exceptions as counsel shall request and as to which the Trustee shall not
      reasonably object; and

            (5) the amount of Debt Securities Outstanding of such series,
      together with the amount of such Debt Securities, does not exceed any
      limit established under the terms of this Indenture on the amount of Debt
      Securities of such series that may be authenticated and delivered.

      The Trustee shall not be required to authenticate such Debt Securities and
Coupons if the issuance of such Debt Securities and Coupons pursuant to this
Indenture will affect the Trustee's own rights, duties or immunities under the
Debt Securities and this Indenture in a manner which is not reasonably
acceptable to the Trustee.

      Each Registered Security shall be dated the date of its authentication.
Each Bearer Security (including any temporary or permanent or other definitive
Bearer Security in global form) shall be dated as of the date of original
issuance of the first Debt Security of such series to be issued, except as
otherwise provided pursuant to Section 3.1 with respect to the Bearer Securities
of any series.

      No Debt Security 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 one of the forms
provided for herein duly executed by the Trustee or by an Authenticating Agent,
and such certificate upon any Debt Security shall be conclusive evidence, and
the only evidence, that such Debt Security has been duly authenticated and

                                       24
<PAGE>

delivered hereunder and is entitled to the benefits of this Indenture.
Notwithstanding the foregoing, if any Debt Security 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 3.8 together with a written statement (which need not
comply with Section 1.2) stating that such Debt Security 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.

      SECTION 3.4. TEMPORARY DEBT SECURITIES; EXCHANGE OF TEMPORARY GLOBAL NOTES
FOR DEFINITIVE BEARER SECURITIES; GLOBAL NOTES REPRESENTING REGISTERED
SECURITIES.

      (a) Pending the preparation of definitive Registered Securities of any
series, the Company may execute, and upon Company Order the Trustee shall
authenticate and deliver, temporary Registered Securities which are printed,
lithographed, typewritten, mimeographed or otherwise produced, in any authorized
denomination for Registered Securities of such series, substantially of the
tenor of the definitive Registered Securities in lieu of which they are issued
and with such appropriate insertions, omissions, substitutions and other
variations as the officers executing such Registered Securities may determine,
as conclusively evidenced by their execution of such Registered Securities.
Every such temporary Registered Security shall be executed by the Company and
shall be authenticated and delivered by the Trustee upon the same conditions and
in substantially the same manner, and with the same effect, as the definitive
Registered Securities in lieu of which they are issued. In the case of any
series issuable as Bearer Securities, such temporary Debt Securities may be in
global form, representing such of the Outstanding Debt Securities of such series
as shall be specified therein.

      Except in the case of temporary Debt Securities in global form (which
shall be exchanged in accordance with the provisions of the following
paragraphs), 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 temporary Debt Securities of such series shall be exchangeable for
definitive Debt Securities of such series, of a like Stated Maturity and with
like terms and provisions, upon surrender of the temporary Debt Securities of
such series at the office or agency of the Company in a Place of Payment for
such series, without charge to the Holder, except as provided in Section 3.5 in
connection with a transfer. Upon surrender for cancellation of any one or more
temporary Debt Securities of any series (accompanied by any unmatured Coupons),
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 authorized denominations and of a like Stated Maturity and like
terms and provisions; provided, however, that no definitive Bearer Security
shall be delivered in exchange for a temporary Registered Security; and
provided, further, that a definitive Bearer Security (including a permanent
Bearer Security in global form) shall be delivered in exchange for a temporary
Bearer Security only in compliance with the conditions set forth in Section 3.3.
Until so exchanged, the temporary Registered Securities of any series shall in
all respects be entitled to the same benefits under this Indenture as definitive
Registered Securities of such series.

                                       25
<PAGE>

      (b) Unless otherwise specified pursuant to Section 3.1, all Bearer
Securities of a series shall be initially issued in the form of a single
temporary Bearer Security in global form (a "temporary Global Note"). The
Company shall execute, and upon Company Order the Trustee shall authenticate,
any temporary Global Note and any permanent Bearer Security in global form (as
described below, a "Permanent Global Note") upon the same conditions and in
substantially the same manner, and with the same effect, as definitive Bearer
Securities, and the temporary or Permanent Global Note, as the case may be,
shall, unless otherwise specified therein, be delivered by the Trustee to the
London office of a depositary or common depositary (the "Common Depositary"),
for the benefit of the Euro-clear Operator or CEDEL, as the case may be, for
credit to the account of the Company (in the case of sales of Bearer Securities
by the Company directly to investors) or the managing underwriter (in the case
of sales of Bearer Securities by the Company to underwriters) or such other
accounts as the Company or the managing underwriter, respectively, may direct.

      On or after the date specified in or determined pursuant to the terms of
any temporary Global Note which (subject to any applicable laws and regulations)
shall be at least 40 days after the issue date of a temporary Global Note (the
"Exchange Date"), the Debt Securities represented by such temporary Global Note
may be exchanged for definitive Debt Securities (subject to the second
succeeding paragraph) or Debt Securities to be represented thereafter by one or
more Permanent Global Notes in definitive form without interest coupons. On or
after the Exchange Date such temporary Global Note shall be surrendered by the
Common Depositary to the Trustee, as the Company's agent for such purpose, at
such address as the Trustee may specify and following such surrender, the
Trustee shall (1) endorse the temporary Global Note to reflect the reduction of
its principal amount by an equal aggregate principal amount of such Debt
Security, (2) endorse the applicable Permanent Global Note, if any, to reflect
the initial amount, or an increase in the amount of Debt Securities represented
thereby, (3) manually authenticate such definitive Debt Securities (including
any Permanent Global Note), (4) deliver such definitive Debt Securities to the
Holder thereof or, if such definitive Debt Security is a Permanent Global Note,
deliver such Permanent Global Note to the Common Depositary to be held outside
the United States for the accounts of the Euro-clear Operator or CEDEL, as the
case may be, for credit to the respective accounts at Euro-clear Operator or
CEDEL, as the case may be, designated by or on behalf of the beneficial owners
of such Debt Securities (or to such other accounts as they may direct) and (5)
redeliver such temporary Global Note to the Common Depositary, unless such
temporary Global Note shall have been canceled in accordance with Section 3.8
hereof; provided, however, that, unless otherwise specified in such temporary
Global Note, upon such presentation by the Common Depositary, such temporary
Global Note shall be accompanied by a certificate dated the Exchange Date or a
subsequent date and signed by the Euro-clear Operator, as to the portion of such
temporary Global Note held for its account then to be exchanged for definitive
Debt Securities (including any Permanent Global Note), and a certificate dated
the Exchange Date or a subsequent date and signed by CEDEL, as to the portion of
such temporary Global Note held for its account then to be exchanged for
definitive Debt Securities (including any Permanent Global Note), each
substantially in the form set forth in Exhibit B to this Indenture. Each
certificate substantially in the form of Exhibit B hereto of the Euro-clear
Operator or CEDEL, as the case may be, shall be based on certificates of the
account holders listed in the records of the Euro-clear Operator or CEDEL, as
the case may be, as being entitled to all or any portion of the applicable
temporary Global Note. An account holder of the Euro-clear Operator or CEDEL, as
the case may be, desiring to effect the exchange of an interest

                                       26
<PAGE>

in a temporary Global Note for an interest in definitive Debt Securities
(including any Permanent Global Note) shall instruct the Euro-clear Operator or
CEDEL, as the case may be, to request such exchange on its behalf and shall
deliver to the Euro-clear Operator or CEDEL, as the case may be, a certificate
substantially in the form of Exhibit A hereto and dated no earlier than 10 days
prior to the Exchange Date. Until so exchanged, temporary Global Notes shall in
all respects be entitled to the same benefits under this Indenture as definitive
Debt Securities (including any Permanent Global Note) of the same series
authenticated and delivered hereunder, except as to payment of interest, if any.

      The delivery to the Trustee by the Euro-clear Operator or CEDEL of any
certificate substantially in the form of Exhibit B hereto may be relied upon by
the Company and the Trustee as conclusive evidence that a corresponding
certificate or certificates has or have been delivered to the Euro-clear
Operator or CEDEL, as the case may be, pursuant to the terms of this Indenture.

      On or prior to the Exchange Date, the Company shall deliver to the Trustee
definitive Debt Securities in an aggregate principal amount equal to the
principal amount of such temporary Global Note, executed by the Company. At any
time, on or after the Exchange Date, upon 30 days' notice to the Trustee by the
Euro-clear Operator or CEDEL, as the case may be, acting at the request of or on
behalf of the beneficial owner, a Debt Security represented by a temporary
Global Note or a Permanent Global Note, as the case may be, may be exchanged, in
whole or from time to time in part, for definitive Debt Securities without
charge and the Trustee shall authenticate and deliver, in exchange for each
portion of such temporary Global Note or such Permanent Global Note, an equal
aggregate principal amount of definitive Debt Securities of the same series of
authorized denominations and of a like Stated Maturity and with like terms and
conditions, as the portion of such temporary Global Note or such Permanent
Global Note to be exchanged, which, unless the Debt Securities of the series are
not issuable both as Bearer Securities and as Registered Securities, as
contemplated by Section 3.1, shall be in the form of Bearer Securities or
Registered Securities, or any combination thereof, as shall be specified by the
beneficial owner thereof; provided, however, that definitive Bearer Securities
shall be delivered in exchange for a portion of the temporary Global Note or the
Permanent Global Note only in compliance with the requirements of the second
preceding paragraph. On or prior to the forty-fifth day following receipt by the
Trustee of such notice with respect to a Debt Security, or, if such day is not a
Business Day, the next succeeding Business Day, the temporary Global Note or the
Permanent Global Note, as the case may be, shall be surrendered by the Common
Depositary to the Trustee, as the Company's agent for such purpose, to be
exchanged, in whole or from time to time in part, for definitive Debt Securities
without charge following such surrender, upon the request of the Euro-clear
Operator or CEDEL, as the case may be, and the Trustee shall (1) endorse the
applicable temporary Global Note or the Permanent Global Note to reflect the
reduction of its principal amount by the aggregate principal amount of such Debt
Security, (2) cause the terms of such Debt Security and Coupons, if any, to be
entered on a definitive Debt Security, (3) manually authenticate such definitive
Debt Security, and (4) if a Bearer Security is to be delivered, deliver such
definitive Debt Security to an address outside the United States to the
Euro-clear Operator or CEDEL, as the case may be, for or on behalf of the
beneficial owner thereof, in exchange for a portion of such temporary Global
Note or the Permanent Global Note.

                                       27
<PAGE>

      Unless otherwise specified in such temporary Global Note or the Permanent
Global Note, any such exchange shall be made free of charge to the beneficial
owners of such temporary Global Note or the Permanent Global Note, 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 the
Euro-clear Operator or CEDEL. Definitive Debt Securities in bearer form to be
delivered in exchange for any portion of a temporary Global Note or the
Permanent Global Note shall be delivered only to an address outside the United
States. Notwithstanding the foregoing, in the event of redemption or
acceleration of all or any part of a temporary Global Note prior to the Exchange
Date, a Permanent Global Note or definitive Bearer Securities, as the case may
be, will not be issuable in respect of such temporary Global Note or such
portion thereof, and payment thereon will instead be made as provided in such
temporary Global Note.

      Until exchanged in full as hereinabove provided, any temporary Global Note
or the Permanent Global Note shall in all respects be entitled to the same
benefits under this Indenture as definitive Debt Securities of the same series
and tenor authenticated and delivered hereunder, except that, unless otherwise
specified as contemplated by Section 3.1, interest payable on such temporary
Global Note on an Interest Payment Date for Debt Securities of such series
occurring prior to the applicable Exchange Date shall be payable to the
Euro-clear Operator or CEDEL on such Interest Payment Date upon delivery by the
Euro-clear Operator or CEDEL to the Trustee of a certificate or certificates
substantially in the form set forth in Exhibit B to this Indenture, 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 Note on such Interest Payment Date and who have each delivered
to the Euro-clear Operator or CEDEL, as the case may be, a certificate
substantially in the form set forth in Exhibit A to this Indenture.

      Any definitive Bearer Security authenticated and delivered by the Trustee
in exchange for a portion of a temporary Global Note or the Permanent Global
Note shall not bear a coupon for any interest which shall theretofore have been
duly paid by the Trustee to the Euro-clear Operator or CEDEL, or by the Company
to the Trustee in accordance with the provisions of this Section 3.4.

      With respect to Exhibits A and B to this Indenture, the Company may, in
its discretion and if required or desirable under applicable law or as set forth
in any Board Resolution or Supplemental Indenture with respect to any Series of
Debt Securities, substitute one or more other forms of such exhibits for such
exhibits, eliminate the requirement that any or all certificates be provided, or
change the time that any certificate may be required, provided that such
substitute form or forms or notice of elimination or change of such
certification requirement have theretofore been delivered to the Trustee with a
Company Request and such form or forms, elimination or change is reasonably
acceptable to the Trustee.

      (c) If the Company shall establish pursuant to Section 3.1 that the
Registered Securities of a series are to be issued in whole or in part in the
form of one or more Global Notes, then the Company shall execute and the Trustee
shall, in accordance with Section 3.3 and the Company Order with respect to such
series, authenticate and deliver one or more Global Notes in temporary or
Permanent form that (i) shall represent and shall be denominated in an amount
equal to the aggregate principal amount of the Outstanding Debt Securities of
such series to be

                                       28
<PAGE>

represented by one or more Global Notes, (ii) shall be registered in the name of
the U.S. Depositary for such Global Note or Notes or the nominee of such
depositary, and (iii) shall bear a legend substantially to the following effect:
"This Debt Security may not be transferred except as a whole by the Depositary
to a nominee of the Depositary or by a nominee of the Depositary to the
Depositary or another nominee of the Depositary or by the Depositary or any such
nominee to a successor Depositary or a nominee of such successor Depositary,
unless and until this Debt Security is exchanged in whole or in part for Debt
Securities in definitive form."

      Notwithstanding any other provision of this Section 3.4 or Section 3.5,
unless and until it is exchanged in whole or in part for Registered Securities
in definitive form, a Global Note representing all or a portion of the
Registered Securities of a series may not be transferred except as a whole by
the U.S. Depositary for such series to a nominee of such depositary or by a
nominee of such depositary to such depositary or another nominee of such
depositary or by such depositary or any such nominee to a successor U.S.
Depositary for such series or a nominee of such successor depositary.

      If at any time the U.S. Depositary for the Debt Securities of a series
notifies the Company that it is unwilling or unable to continue as U.S.
Depositary for the Debt Securities of such series or if at any time the U.S.
Depositary for Debt Securities of a series shall no longer be a clearing agency
registered and in good standing under the Securities Exchange Act of 1934, as
amended, or other applicable statute or regulation, the Company shall appoint a
successor U.S. Depositary with respect to the Debt Securities of such series. If
a successor U.S. 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 condition, 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,
Registered Securities of such series in definitive form in an aggregate
principal amount equal to the principal amount of the Global Note or Notes
representing such series in exchange for such Global Note or Notes.

      The Company may at any time and in its sole discretion determine that the
Registered Securities of any series issued in the form of one or more Global
Notes shall no longer be represented by such Global Note or Notes. 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, Registered Securities of such series in
definitive form and in an aggregate principal amount equal to the principal
amount of the Global Note or Notes representing such series in exchange for such
Global Note or Notes.

      If the Registered Securities of any series shall have been issued in the
form of one or more Global Notes and if an Event of Default with respect to the
Debt Securities of such series shall have occurred and be continuing, the
Company will promptly 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, Registered Securities of such series in
definitive form and in an aggregate principal amount equal to the principal
amount of the Global Note or Notes representing such series in exchange for such
Global Note or Notes.

      If specified by the Company pursuant to Section 3.1 with respect to
Registered Securities of a series, the U.S. Depositary for such series of
Registered Securities may surrender a Global

                                       29
<PAGE>

Note for such series of Debt Securities in exchange in whole or in part for
Registered Securities of such series 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:

            (i) to each Person specified by the U.S. Depositary a new Registered
      Security or Securities of the same series, of any authorized denomination
      as requested by such Person in an aggregate principal amount equal to and
      in exchange for such Person's beneficial interest in the Global Note; and

            (ii) to the U.S. Depositary a new Global Note in a denomination
      equal to the difference, if any, between the principal amount of the
      surrendered Global Note and the aggregate principal amount of Registered
      Securities delivered to Holders thereof.

      Upon the exchange of a Global Note for Registered Securities in definitive
form, such Global Note shall be canceled by the Trustee. Debt Securities issued
in exchange for a Global Note pursuant to this subsection (c) shall be
registered in such names and in such authorized denominations as the U.S.
Depositary for such Global Note, pursuant to instructions from its direct or
indirect participants or otherwise, shall instruct the Trustee. The Trustee
shall deliver such Debt Securities to the Persons in whose names such Debt
Securities are so registered.

      SECTION 3.5. REGISTRATION, TRANSFER AND EXCHANGE.

      (a) The Company shall cause to be kept at the Corporate Trust Office of
the Trustee a register (the registers maintained in such office and in any other
office or agency of the Company in a Place of Payment being herein sometimes
collectively 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 and exchanges of
Registered Securities. Such Security Register shall be in written form in the
English language or in any other form capable of being accurately and completely
converted into such form within a reasonable time. The Trustee is hereby
appointed "Security Registrar" for the purpose of registering Registered
Securities and registering transfers and exchanges of Registered Securities as
herein provided; provided, however, that the Company may appoint co-Security
Registrars or the terms of any series of Debt Securities may provide otherwise.

      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, one or more new Registered Securities of
the same series of like aggregate principal amount of such denominations as are
authorized for Registered Securities of such series and of a like Stated
Maturity and with like terms and conditions.

      Except as otherwise provided in Section 3.4 and this Section 3.5, at the
option of the Holder, Registered Securities of any series may be exchanged for
other Registered Securities of the same series of like aggregate principal
amount and of a like Stated Maturity and with like terms and conditions, upon
surrender of the Registered Securities to be exchanged at such office

                                       30
<PAGE>

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

      (b) If and to the extent specified pursuant to Section 3.1, the provisions
of this Section 3.5(b) shall be applicable to Debt Securities of any series
which are Bearer Securities. At the option of the Holder thereof, to the extent
permitted by law, any Bearer Security of any series which by its terms is
registrable as to principal and interest may be exchanged for a Registered
Security of such series of like aggregate principal amount and of a like Stated
Maturity and with like terms and conditions upon surrender of such Bearer
Security at the Corporate Trust Office or at any other office or agency of the
Company designated pursuant to Section 3.1 for the purpose of making any such
exchanges. Any Coupon Security surrendered for exchange shall be surrendered
with all unmatured Coupons and any matured Coupons in default attached thereto.
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 in an amount equal to the face amount of such missing Coupon or
Coupons, or the surrender of such missing Coupon or Coupons may be waived by the
Company and the Trustee if there is furnished to them such security or indemnity
as they may require to save each of them and any Paying Agent harmless. If
thereafter the Holder of such Bearer Security shall surrender to any Paying
Agent any such missing Coupon in respect of which such a payment shall have been
made, such Holder shall be entitled to receive the amount of such payment;
provided, however, that except as otherwise provided in Section 12.3, 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 of a like Stated Maturity and with like terms and
conditions after the close of business at such office or agency on (i) any
Regular Record Date and before the opening of business at such office or agency
on the relevant Interest Payment Date, or (ii) any Special Record Date and
before the opening of business at such office or agency on the related proposed
date for payment of Defaulted Interest, such Bearer Security shall be
surrendered without the Coupon relating to such Interest Payment Date or
proposed date for payment, as the case may be (or, if such Coupon is so
surrendered with such Bearer Security, such Coupon shall be returned to the
Person so surrendering the Bearer Security), and interest or Defaulted Interest,
as the case may be, will not be payable on such Interest Payment Date or
proposed date for payment, as the case may be, in respect of the Registered
Security issued in exchange for such Bearer Security, but will be payable only
to the Holder of such Coupon when due in accordance with the provisions of this
Indenture. The Company shall execute, and the Trustee shall authenticate and
deliver, the Registered Security or Securities which the Holder making the
exchange is entitled to receive.

      Notwithstanding the foregoing, the exchange of Bearer Securities for
Registered Securities will be subject to the provisions of United States income
tax laws and regulations applicable to Debt Securities in effect at the time of
such exchange.

                                       31
<PAGE>

      (c) Except as otherwise specified pursuant to Section 3.1, in no event may
Registered Securities, including Registered Securities received in exchange for
Bearer Securities, be exchanged for Bearer Securities.

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

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

      No service charge will be made for any transfer or exchange of Debt
Securities except as provided in Section 3.4(b) or 3.6. 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 registration, transfer or exchange of Debt
Securities, other than those 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 register, transfer or exchange
Debt Securities of any series during a period beginning at the opening of
business 15 days before the day of the transmission of a notice of redemption of
Debt Securities of such series selected for redemption under Section 13.3 and
ending at the close of business on the day of such transmission, or (ii) to
register, transfer or exchange any Debt Security so selected for redemption in
whole or in part, except the unredeemed portion of any Debt Security being
redeemed in part.

      SECTION 3.6. MUTILATED, DESTROYED, LOST AND STOLEN DEBT SECURITIES.

      If (i) any mutilated Debt Security or any mutilated Coupon with the Coupon
Security to which it appertains (and all unmatured Coupons attached thereto) is
surrendered to the Trustee at its Corporate Trust Office, or (ii) the Company
and the Trustee receive evidence to their satisfaction of the destruction, loss
or theft of any Debt Security or any 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 and any Paying Agent harmless, and neither the Company nor the
Trustee receives notice that such Debt Security or Coupon has been acquired by a
bona fide purchaser, then the Company shall execute and upon Company Request the
Trustee shall authenticate and deliver, in exchange for or in lieu of any such
mutilated, destroyed, lost or stolen Debt Security or in exchange for the Coupon
Security to which such mutilated, destroyed, lost or stolen Coupon appertained,
a new Debt Security of the same series of like Stated Maturity and with like
terms and conditions and like principal amount, bearing a number not
contemporaneously Outstanding, and, in the case of a Coupon Security, with such
Coupons attached thereto that neither gain nor loss in interest shall result
from such exchange or substitution.

      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 the amount due on
such Debt Security or Coupon in accordance with its

                                       32
<PAGE>

terms; provided, however, that principal of (and premium, if any) and any
interest on Bearer Securities shall, except as otherwise provided in Section
12.3, be payable only at an office or agency located outside the United States
and, unless otherwise specified as contemplated by Section 3.1 or except as
otherwise provided in this Section 3.6, any interest on Bearer Securities shall
be payable only upon presentation and surrender of the Coupons appertaining
thereto.

      Upon the issuance of any new Debt Security 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 respect thereto and any other
expenses (including the fees and expenses of the Trustee) connected therewith.

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

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

      SECTION 3.7. PAYMENT OF INTEREST; INTEREST RIGHTS PRESERVED.

      (a) Unless otherwise specified as contemplated by Section 3.1 with respect
to the Debt Securities of any series, 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 such Registered Security (or one
or more Predecessor Securities) is registered at the close of business on the
Regular Record Date for such interest notwithstanding the cancellation of such
Registered Security upon any transfer or exchange subsequent to the Regular
Record Date. Unless otherwise specified as contemplated by Section 3.1 with
respect to the Debt Securities of any series, payment of interest on Registered
Securities shall be made at the place or places specified pursuant to Section
3.1 or, at the option of the Company, by check mailed to the address of the
Person entitled thereto as such address shall appear in the Security Register
or, if provided pursuant to Section 3.1, by wire transfer to an account
designated by the Registered Holder.

      (b) Interest on any Coupon Security which is payable and is punctually
paid or duly provided for on any Interest Payment Date shall be paid to the
Holder of the Coupon which has matured on such Interest Payment Date upon
surrender of such Coupon on such Interest Payment Date at the Corporate Trust
Office of the Trustee or at such other Place of Payment outside the United
States specified pursuant to Section 3.1.

      Interest on any Bearer Security (other than a Coupon Security) which is
payable and is punctually paid or duly provided for on any Interest Payment Date
shall be paid to the Holder of the Bearer Security upon presentation of such
Bearer Security and notation thereon on such Interest Payment Date at the
Corporate Trust Office of the Trustee or at such other Place of Payment
maintained by the Company outside the United States specified pursuant to
Section 3.1.

                                       33
<PAGE>

      Unless otherwise specified pursuant to Section 3.1, at the direction of
the Holder of any Bearer Security or Coupon payable in Dollars, payment on such
Bearer Security or Coupon will be made by check drawn on a bank in The City of
[____] or, if agreeable to the Trustee, by wire transfer to a Dollar account
maintained by such Holder outside the United States. If such payment at the
offices of all Paying Agents outside the United States becomes illegal or is
effectively precluded because of the imposition of exchange controls or similar
restrictions on the full payment or receipt of such amounts in Dollars, the
Company will appoint an office or agent in the United States at which such
payment may be made. Unless otherwise specified pursuant to Section 3.1, at the
direction of the Holder of any Bearer Security or Coupon payable in a Foreign
Currency, payment on such Bearer Security or Coupon will be made by a check
drawn on a bank outside the United States or by wire transfer to an appropriate
account maintained by such Holder outside the United States. Except as provided
in this paragraph, no payment on any Bearer Security or Coupon will be made by
mail to an address in the United States or by wire transfer to an account in the
United States.

      (c) Any interest on any Debt Security which is payable but is not
punctually paid or duly provided for on any Interest Payment Date (herein called
"Defaulted Interest") shall, if such Debt Security is a Registered Security,
forthwith cease to be payable to the Registered Holder on the relevant Regular
Record Date by virtue of his having been such Registered 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 such Registered Securities (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 such Registered Security and the date of the proposed payment, and
      at the same time the Company shall deposit with the Trustee an amount of
      money in the Currency or Currency unit in which the Debt Securities of
      such series are payable (except as otherwise specified pursuant to
      Sections 3.1 or 3.10) equal to the aggregate amount proposed to be paid in
      respect of such Defaulted Interest or shall make arrangements satisfactory
      to the Trustee for such deposit prior to the date of the proposed payment,
      such money when deposited to be held in trust for the benefit of the
      Persons entitled to such Defaulted Interest as in this clause provided.
      Thereupon the Trustee shall fix a Special Record Date for the payment of
      such Defaulted Interest which date shall be not more than 15 days and not
      less than 10 days prior to the date of the proposed payment and not less
      than 10 days after the receipt by the Trustee of the notice of the
      proposed payment. The Trustee shall promptly notify the Company of such
      Special Record Date and, in the name and at the expense of the Company,
      shall cause notice of the proposed payment of such Defaulted Interest and
      the Special Record Date therefor to be mailed, first-class postage
      prepaid, to the Holders of such Registered Securities at their addresses
      as they appear 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,

                                       34
<PAGE>

      such Defaulted Interest shall be paid to the Persons in whose names such
      Registered Securities (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).

            (2) The Company may make payment of any Defaulted Interest on
      Registered Securities in any other lawful manner not inconsistent with the
      requirements of any securities exchange on which such 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.

      (d) Any Defaulted Interest payable in respect of Bearer Securities of any
series shall be payable pursuant to such procedures as may be satisfactory to
the Trustee in such manner that there is no discrimination between the Holders
of Registered Securities (if any) and Bearer Securities of such series, and
notice of the payment date therefor shall be given by the Trustee, in the name
and at the expense of the Company, in the manner provided in Section 1.5 not
more than 25 days and not less than 20 days prior to the date of the proposed
payment.

      (e) Subject to the foregoing provisions of this Section, each Debt
Security delivered under this Indenture upon 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.

      SECTION 3.8. CANCELLATION.

      Unless otherwise specified pursuant to Section 3.1 for Debt Securities of
any series, all Debt Securities surrendered for payment, redemption, transfer,
exchange or credit against any sinking fund and all Coupons surrendered for
payment or exchange shall, if surrendered to any Person other than the Trustee,
be delivered to the Trustee. All Registered Securities and matured Coupons so
delivered shall be promptly canceled by the Trustee. All Bearer Securities and
unmatured Coupons so delivered shall be held by the Trustee and, upon
instruction by the Company Order, shall be canceled or held for reissuance.
Bearer Securities and unmatured Coupons held for reissuance may be reissued only
in exchange for Bearer Securities of the same series and of like Stated Maturity
and with like terms and conditions pursuant to Section 3.5 or in replacement of
mutilated, lost, stolen or destroyed Bearer Securities of the same series and of
like Stated Maturity and with like terms and conditions or the related Coupons
pursuant to Section 3.6. All Bearer Securities and unmatured Coupons held by the
Trustee pending such cancellation or reissuance shall be deemed to be delivered
for cancellation for all purposes of this Indenture and the Securities. The
Company may at any time deliver to the Trustee for cancellation any Debt
Securities or Coupons previously authenticated and delivered hereunder which the
Company may have acquired in any manner whatsoever, and may deliver to the
Trustee (or to any other Person for delivery to the Trustee) for cancellation
any Debt Securities previously authenticated hereunder which the Company has not
issued, and all Debt Securities or Coupons so delivered shall be promptly
canceled by the Trustee. No Debt Securities or Coupons shall be authenticated in
lieu of or in exchange for any Debt Securities or Coupons canceled as provided
in this Section, except as expressly permitted by this Indenture. All canceled
Debt

                                       35
<PAGE>

Securities and Coupons held by the Trustee shall be delivered to the Company
upon Company Request. The acquisition of any Debt Securities or Coupons by the
Company shall not operate as a redemption or satisfaction of the indebtedness
represented thereby unless and until such Debt Securities or Coupons are
surrendered to the Trustee for cancellation. In the case of any temporary Global
Note which shall be destroyed if the entire aggregate principal amount of the
Debt Securities represented thereby has been exchanged, the certificate of
destruction shall state that all certificates required pursuant to Section 3.4
hereof and substantially in the form of Exhibit B hereto, to be given by the
Euro-clear Operator or CEDEL, have been duly presented to the Trustee by the
Euro-clear Operator or CEDEL, as the case may be. Permanent Global Notes shall
not be destroyed until exchanged in full for definitive Debt Securities or until
payment thereon is made in full.

      SECTION 3.9. COMPUTATION OF INTEREST.

      Except as otherwise specified pursuant to Section 3.1 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 3.10. CURRENCY OF PAYMENTS IN RESPECT OF DEBT SECURITIES.

      (a) Except as otherwise specified pursuant to Section 3.1 for Bearer
Securities of any series, payment of the principal of (and premium, if any) and
interest on Bearer Securities of such series denominated in any Currency will be
made in such Currency.

      (b) With respect to Registered Securities of any series not permitting the
election provided for in paragraph (c) below or the Holders of which have not
made the election provided for in paragraph (c) below, except as provided in
paragraph (e) below, payment of the principal of (and premium, if any) and any
interest on any Registered Security of such series will be made in the Currency
in which such Registered Security is payable.

      (c) It may be provided pursuant to Section 3.1 with respect to the
Registered Securities of any series that Holders shall have the option, subject
to paragraphs (e) and (f) below (and provided that in no instance may such
election be made after a defeasance pursuant to Article XV or during the
continuance of an Event of Default), to receive payments of principal of (and
premium, if any) and any interest on such Registered Securities in any of the
Currencies which may be designated for such election in the applicable
supplemental indenture by delivering to the Trustee a written election, to be in
form and substance satisfactory to the Trustee, not later than the close of
business on the Election Date immediately preceding the applicable payment date.
If a Holder so elects to receive such payments in any such Currency, such
election will remain in effect for such Holder or any transferee of such Holder
until changed by such Holder or such transferee by written notice to the Trustee
(but any such change must be made not later than the close of business on the
Election Date immediately preceding the next payment date to be effective for
the payment to be made on such payment date and no such change or election may
be made with respect to payments to be made on any Registered Security of such
series with respect to which an Event of Default has occurred or notice of
redemption has been given by the Company pursuant to Article XIII). Any Holder
of any such Registered Security who shall not have delivered any such election
to the Trustee by the close of business

                                       36
<PAGE>

on the applicable Election Date will be paid the amount due on the applicable
payment date in the relevant Currency as provided in paragraph (b) of this
Section 3.10.

      (d) If the election referred to in paragraph (c) above has been provided
for pursuant to Section 3.1, then not later than the fourth Business Day after
the Election Date for each payment date, the Trustee will deliver to the Company
a written notice specifying, in the Currency in which each series of the
Registered Securities is payable, the respective aggregate amounts of principal
of (and premium, if any) and any interest on the Registered Securities to be
paid on such payment date, specifying the amounts so payable in respect of the
Registered Securities as to which the Holders of Registered Securities
denominated in any Currency shall have elected to be paid in another Currency as
provided in paragraph (c) above. If the election referred to in paragraph (c)
above has been provided for pursuant to Section 3.1 and if at least one Holder
has made such election, then, on the second Business Day preceding each payment
date, the Company will deliver to the Trustee an Exchange Rate Officer's
Certificate in respect of the Currency payments to be made on such payment date.
The Currency amount receivable by Holders of Registered Securities who have
elected payment in a Currency as provided in paragraph (c) above shall be
determined by the Company on the basis of the applicable Market Exchange Rate in
effect on the third Business Day (the "Valuation Date") immediately preceding
each payment date.

      (e) If a Conversion Event occurs with respect to a Foreign Currency, the
ECU or any other Currency unit in which any of the Debt Securities are
denominated or payable other than pursuant to an election provided for pursuant
to paragraph (c) above, then with respect to each date for the payment of
principal of (and premium, if any) and any interest on the applicable Debt
Securities denominated or payable in such Foreign Currency, the ECU or such
other Currency unit occurring after the last date on which such Foreign
Currency, the ECU or such other Currency unit was used (the "Conversion Date"),
the Dollar shall be the Currency of payment for use on each such payment date.
The Dollar amount to be paid by the Company to the Trustee and by the Trustee or
any Paying Agent to the Holders of such Debt Securities with respect to such
payment date shall be the Dollar Equivalent of the Foreign Currency or, in the
case of a Currency unit, the Dollar Equivalent of the Currency Unit, in each
case as determined by the Currency Determination Agent, if any, or, if there
shall not be a Currency Determination Agent, then by the Trustee, in the manner
provided in paragraph (g) or (h) below.

      (f) If the Holder of a Registered Security denominated in any Currency
shall have elected to be paid in another Currency as provided in paragraph (c)
above, and a Conversion Event occurs with respect to such elected Currency, such
Holder shall receive payment in the Currency in which payment would have been
made in the absence of such election. If a Conversion Event occurs with respect
to the Currency in which payment would have been made in the absence of such
election, such Holder shall receive payment in Dollars as provided in paragraph
(e) of this Section 3.10.

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

                                       37
<PAGE>

      (h) The "Dollar Equivalent of the Currency Unit" shall be determined by
the Currency Determination Agent, and subject to the provisions of paragraph (i)
below, shall be the sum of each amount obtained by converting the Specified
Amount of each Component Currency into Dollars at the Market Exchange Rate for
such Component Currency on the Valuation Date with respect to each payment.

      (i) For purposes of this Section 3.10 the following terms shall have the
following meanings:

            A "Component Currency" shall mean any Currency which, on the
      Conversion Date, was a component Currency of the relevant Currency unit,
      including, but not limited to, the ECU.

            A "Specified Amount" of a Component Currency shall mean the number
      of units of such Component Currency or fractions thereof which were
      represented in the relevant Currency unit, including, but not limited to,
      the ECU, on the Conversion Date. If after the Conversion Date the official
      unit of any Component Currency is altered by way of combination or
      subdivision, the Specified Amount of such Component Currency shall be
      divided or multiplied in the same proportion. If after the Conversion Date
      two or more Component Currencies are consolidated into a single Currency,
      the respective Specified Amounts of such Component Currencies shall be
      replaced by an amount in such single Currency equal to the sum of the
      respective Specified Amounts of such consolidated Component Currencies
      expressed in such single Currency, and such amount shall thereafter be a
      Specified Amount and such single Currency shall thereafter be a Component
      Currency. If after the Conversion Date any Component Currency shall be
      divided into two or more Currencies, the Specified Amount of such
      Component Currency shall be replaced by amounts of such two or more
      Currencies with appropriate Dollar equivalents at the Market Exchange Rate
      on the date of such replacement equal to the Dollar equivalent of the
      Specified Amount of such former Component Currency at the Market Exchange
      Rate on such date, and such amounts shall thereafter be Specified Amounts
      and such Currencies shall thereafter be Component Currencies. If after the
      Conversion Date of the relevant Currency unit, including but not limited
      to, the ECU, a Conversion Event (other than any event referred to above in
      this definition of "Specified Amount") occurs with respect to any
      Component Currency of such Currency unit, the Specified Amount of such
      Component Currency shall, for purposes of calculating the Dollar
      Equivalent of the Currency Unit, be converted into Dollars at the Market
      Exchange Rate in effect on the Conversion Date of such Component Currency.

            "Election Date" shall mean the earlier of (i) the seventh Business
      Day immediately preceding any payment date or (ii) the record date with
      respect to any payment date, and with respect to the Maturity shall mean
      the record date (if within 16 or fewer days prior to the Maturity)
      immediately preceding the Maturity, and with respect to any series of Debt
      Securities whose record date immediately preceding the Maturity is more
      than 16 days prior to the Maturity or

                                       38
<PAGE>

      any series of Debt Securities for which no record dates are provided with
      respect to interest payments, shall mean the date which is 16 days prior
      to the Maturity.

      (j) All decisions and determinations of the Trustee or the Currency
Determination Agent, if any, regarding the Dollar Equivalent of the Foreign
Currency, the Dollar Equivalent of the Currency Unit and the Market Exchange
Rate shall be in its sole discretion and shall, in the absence of manifest
error, be conclusive for all purposes and irrevocably binding upon the Company
and all Holders of the Debt Securities denominated or payable in the relevant
Currency. In the event of a Conversion Event with respect to a Foreign Currency,
the Company, after learning thereof, will immediately give written notice
thereof to the Trustee (and the Trustee will promptly thereafter give notice in
the manner provided in Section 1.5 to the Holders) specifying the Conversion
Date. In the event of a Conversion Event with respect to the ECU or any other
Currency unit in which Debt Securities are denominated or payable, the Company,
after learning thereof, will immediately give notice thereof to the Trustee (and
the Trustee will promptly thereafter give written notice in the manner provided
in Section 1.5 to the Holders) specifying the Conversion Date and the Specified
Amount of each Component Currency on the Conversion Date. In the event of any
subsequent change in any Component Currency as set forth in the definition of
Specified Amount above, the Company, after learning thereof, will similarly give
written notice to the Trustee. The Trustee shall be fully justified and
protected in relying and acting upon information received by it from the Company
and the Currency Determination Agent, if any, and shall not otherwise have any
duty or obligation to determine such information independently.

      (k) For purposes of any provision of the Indenture where the Holders of
Outstanding Debt Securities may perform an Act which requires that a specified
percentage of the Outstanding Debt Securities of all series perform such Act and
for purposes of any decision or determination by the Trustee of amounts due and
unpaid for the principal (and premium, if any) and interest on the Debt
Securities of all series in respect of which moneys are to be disbursed ratably,
the principal of (and premium, if any) and interest on the Outstanding Debt
Securities denominated in a Foreign Currency will be the amount in Dollars based
upon the Market Exchange Rate for Debt Securities of such series, as of the date
for determining whether the Holders entitled to perform such Act have performed
it, or as of the date of such decision or determination by the Trustee, as the
case may be.

      (l) The Company hereby appoints itself as the initial Currency
Determination Agent and the Company shall be entitled to remove such agent at
any time; provided, however, that such removal shall not be effective and the
agent may not resign until a successor has been appointed by the Company and the
successor has accepted such appointment. The Trustee is under no duty or
obligation to serve in the capacity of Currency Determination Agent.

      SECTION 3.11. JUDGMENTS.

      If for the purpose of obtaining a judgment in any court with respect to
any obligation of the Company hereunder or under any Debt Security, it shall
become necessary to convert into any other Currency any amount in the Currency
due hereunder or under such Debt Security, then such conversion shall be made at
the Market Exchange Rate as in effect on the date the Company shall make payment
to any Person in satisfaction of such judgment. If pursuant to any such

                                       39
<PAGE>

judgment, conversion shall be made on a date other than the date payment is made
and there shall occur a change between such Market Exchange Rate and the Market
Exchange Rate as in effect on the date of payment, the Company agrees to pay
such additional amounts (if any) as may be necessary to ensure that the amount
paid is equal to the amount in such other Currency which, when converted at the
Market Exchange Rate as in effect on the date of payment or distribution, is the
amount then due hereunder or under such Debt Security. Any amount due from the
Company under this Section 3.11 shall be due as a separate debt and is not to be
affected by or merged into any judgment being obtained for any other sums due
hereunder or in respect of any Debt Security. In no event, however, shall the
Company be required to pay more in the Currency or Currency unit due hereunder
or under such Debt Security at the Market Exchange Rate as in effect when
payment is made than the amount of Currency stated to be due hereunder or under
such Debt Security so that in any event the Company's obligations hereunder or
under such Debt Security will be effectively maintained as obligations in such
Currency, and the Company shall be entitled to withhold (or be reimbursed for,
as the case may be) any excess of the amount actually realized upon any such
conversion over the amount due and payable on the date of payment or
distribution.

      SECTION 3.12. EXCHANGE UPON DEFAULT.

      If default is made in the payments referred to in Section 12.1, the
Company hereby undertakes that upon presentation and surrender of a Permanent
Global Note to the Trustee (or to any other Person or at any other address as
the Company may designate in writing), on any Business Day on or after the
maturity date thereof the Company will issue and the Trustee will authenticate
and deliver to the bearer of such Permanent Global Note duly executed and
authenticated definitive Debt Securities with the same issue date and maturity
date as set out in such Permanent Global Note.

                                   ARTICLE IV.

                           SATISFACTION AND DISCHARGE

      SECTION 4.1. SATISFACTION AND DISCHARGE OF INDENTURE.

      This Indenture, with respect to the Debt Securities of any series (if all
series issued under this Indenture are not to be affected), shall, upon Company
Request, cease to be of further effect (except as to any surviving rights of
registration of transfer or exchange of such Debt Securities herein expressly
provided for and rights to receive payments of principal (and premium, if any)
and interest on such Debt Securities) 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 and the Coupons, if any, of such series
      theretofore authenticated and delivered (other than (i) Debt Securities
      and Coupons of such series which have been destroyed, lost or stolen and
      which have been replaced or paid as provided in Section 3.6, (ii) Coupons
      appertaining to Bearer Securities surrendered for exchange for Registered
      Securities and maturing

                                       40
<PAGE>

      after such exchange, whose surrender is not required or has been waived
      under Section 3.5, (iii) Coupons appertaining to Bearer Securities called
      for redemption and maturing after the relevant Redemption Date, whose
      surrender has been waived as provided in Section 13.6, and (iv) Debt
      Securities and Coupons of such series for whose payment money has
      theretofore been deposited in trust or segregated and held in trust by the
      Company and thereafter repaid to the Company or discharged from such
      trust, as provided in Section 12.4) have been delivered to the Trustee for
      cancellation; or

            (B) all Debt Securities and the Coupons, if any, of such series not
      theretofore delivered to the Trustee for cancellation,

                (i) have become due and payable by reason of the making of a
            notice of redemption or otherwise, or

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

            and the Company, either complies with any other condition or terms
            specified pursuant to Section 3.1, or if not so specified in the
            case of (i), (ii) or (iii) of this subclause (B), has irrevocably
            deposited or caused to be deposited with the Trustee as trust funds
            held in trust solely for the benefit of the Holders, cash in United
            States Dollars, non-callable government securities, or a combination
            thereof, in such amounts as will be (except as otherwise provided
            pursuant to Section 3.1 or 3.10) sufficient without consideration of
            any reinvestment of interest, to pay and discharge the entire
            indebtedness on such Debt Securities not delivered to the Trustee
            for cancellation for principal, premium, if any and accrued interest
            to the date of such deposit (in the case of Debt Securities which
            have become due and payable) or to the Stated Maturity or Redemption
            Date, as the case may be;

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

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

Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Company to the Trustee under Section 6.7, the obligations of
the Trustee to any Authenticating Agent under Section 6.14, the obligations of
the Company under Section 12.1, and, if money shall have been deposited with the
Trustee pursuant to subclause (B) of clause (1) of this Section 4.1, the
obligations of the Trustee under Section 4.2 and the last paragraph of Section
12.4, shall survive. If, after the deposit referred to in Section 4.1 has been
made, (x) the Holder of a Debt Security is entitled to, and does, elect pursuant
to Section 3.10(c), to receive payment in a Currency other

                                       41
<PAGE>

than that in which the deposit pursuant to Section 4.1 was made, or (y) if a
Conversion Event occurs with respect to the Currency in which the deposit was
made or elected to be received by the Holder pursuant to Section 3.10(c), then
the indebtedness represented by such Debt Security shall be fully discharged to
the extent that the deposit made with respect to such Debt Security shall be
converted into the Currency in which such payment is made.

      SECTION 4.2. APPLICATION OF TRUST MONEY.

      Subject to the provisions of the last paragraph of Section 12.4, all money
deposited with the Trustee pursuant to Section 4.1 shall be held in trust and
applied by it, in accordance with the provisions of the Debt Securities and
Coupons, if any, and this Indenture, to the payment, either directly or through
any Paying Agent (including the Company acting as its own Paying Agent) as the
Trustee may determine, to the Persons entitled thereto, of the principal (and
premium, if any) and interest for whose payment such money has been deposited
with the Trustee.

                                   ARTICLE V.

                                    REMEDIES

      SECTION 5.1. EVENTS OF DEFAULT.

      "Event of Default" wherever used herein with respect to Debt Securities of
any series, and unless otherwise provided with respect to Debt Securities of any
series pursuant to Section 3.1, means any one of the following events (whatever
the reason for such Event of Default and whether it shall be voluntary or
involuntary or be effected by operation of law, pursuant to any judgment, decree
or order of any court or any order, rule or regulation of any administrative or
governmental body):

            (1) default in the payment of any interest upon any Debt Security or
      any payment with respect to the Coupons, if any, of such series when it
      becomes due and payable, and continuance of such default for a period of
      30 days; or

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

            (3) default in the deposit of any sinking fund payment, when and as
      due by the terms of a Debt Security of such series, and the continuance of
      such default for a period of 30 days; or

            (4) default in the performance, or breach, of any covenant or
      warranty of the Company in this Indenture (other than a covenant or
      warranty a default in whose performance or whose breach is elsewhere in
      this Section specifically dealt with or which expressly has 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 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 Debt
      Securities of such series, a written notice specifying such default or
      breach

                                       42
<PAGE>

      and requiring it to be remedied and stating that such notice is a "Notice
      of Default" hereunder; or

            (5) the entry of a decree or order for relief in respect of the
      Company by a court having jurisdiction in the premises in an involuntary
      case under the Federal bankruptcy laws, as now or hereafter constituted,
      or any other applicable Federal or State bankruptcy, insolvency or other
      similar law, or a decree or order adjudging the Company a bankrupt or
      insolvent, or approving as properly filed a petition seeking
      reorganization, arrangement, adjustment or composition of or in respect of
      the Company under any applicable Federal or State law, or appointing a
      receiver, liquidator, assignee, custodian, 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 unstayed and in effect for a
      period of 90 consecutive days; or

            (6) the commencement by the Company of a voluntary case under the
      Federal bankruptcy laws, as now or hereafter constituted, or any other
      applicable Federal or State bankruptcy, insolvency or other similar law,
      or the consent by it to the entry of an order for relief in an involuntary
      case under any such law or to the appointment of a receiver, liquidator,
      assignee, custodian, trustee, sequestrator (or other 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 its 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

            (7) any other Event of Default provided with respect to Debt
      Securities of that series pursuant to Section 3.1.

      SECTION 5.2. ACCELERATION OF MATURITY; RESCISSION AND ANNULMENT.

      If an Event of Default (unless otherwise provided with respect to Debt
Securities of any series pursuant to Section 3.1, other than an Event of Default
specified in clauses (5) or (6) of Section 5.1) with respect to Debt Securities
of any series at the time Outstanding occurs and is continuing, then in every
such case, unless the principal of all Debt Securities shall have already become
due and payable, the Trustee or the Holders of not less than 25% in principal
amount of the Outstanding Debt Securities of such series may declare the
principal amount (or, if any Debt Securities of such series are Discount
Securities or indexed securities, such portion of the principal amount of such
Discount Securities as may be specified in the terms of such Discount Securities
or indexed securities) of 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 Holders), and upon any such declaration such principal amount (or
specified amount) plus accrued and unpaid interest (and premium, if payable)
shall become immediately due and payable; provided however, that payment of such
principal and interest, if any, on the Debt Securities of such series shall
remain subordinated to the extent provided in Article XVII. Unless otherwise
provided with respect to Debt Securities of any series pursuant to Section 3.1,
if an Event of Default specified in clauses (5) or (6) of Section 5.1 occurs,
such an amount shall ipso facto become and

                                       43
<PAGE>

be immediately due and payable without any declaration or other act on the part
of the Trustee or any Holder. Upon payment of such amount in the Currency in
which such Debt Securities are denominated (except as otherwise provided
pursuant to Sections 3.1 or 3.10), 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 V 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 in the
      Currency in which such Debt Securities are denominated (except as
      otherwise provided pursuant to Section 3.1 or 3.10) sufficient to pay

                  (A)   all overdue installments of interest on all Debt
                        Securities or all overdue payments with respect to any
                        Coupons 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 on each
                        Debt Security of such series or upon overdue payments on
                        any Coupons of such series at the Overdue Rate, and

                  (D)   all sums paid or advanced by the Trustee hereunder and
                        the reasonable compensation, expenses, disbursements and

                        provided, however, that all sums payable under this
                        clause (D) shall be paid in Dollars;

            and

            (2) All Events of Default with respect to Debt Securities of such
      series, other than the nonpayment of the principal of Debt Securities of
      such series which has become due solely by such declaration of
      acceleration, have been cured or waived as provided in Section 5.13.

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

      SECTION 5.3. COLLECTION OF INDEBTEDNESS AND SUITS FOR ENFORCEMENT BY
TRUSTEE.

      The Company covenants that if

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

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

            (3) default is made in the making or satisfaction of any sinking
      fund payment or analogous obligation when the same becomes due pursuant to
      the terms of the Debt Securities of any series, and such default continues
      for a period of 30 days,

the Company will, upon demand of the Trustee, pay to it, for the benefit of the
Holders of such Debt Securities or of such Coupons, the amount then due and
payable on such Debt Securities or matured Coupons, for the principal (and
premium, if any) and interest, if any, 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 Overdue Rate;
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 amount 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 and
Coupons of such series by such appropriate judicial proceedings as the Trustee
shall deem most effectual to protect and enforce any such rights, whether for
the specific enforcement of any covenant or agreement in this Indenture or in
aid of the exercise of any power granted herein, or to enforce any other proper
remedy.

      SECTION 5.4. TRUSTEE MAY FILE PROOFS OF CLAIM.

      In case of 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 and Coupons, if any, of a particular
series or all or substantially all of the property of the Company or of such
other obligor

                                       45
<PAGE>

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 of acceleration 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 proceeding
or otherwise,

            (i) to file and prove a claim for the whole amount of principal (or,
      if the Debt Securities of such series are Discount Securities, such
      portion of the principal amount as may be due and payable with respect to
      such series pursuant to a declaration in accordance with Section 5.2) (and
      premium, if any) and interest owing and unpaid in respect of the Debt
      Securities and Coupons of such series 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 of such Debt Securities and Coupons allowed in
      such judicial proceeding, and

            (ii) to collect and receive any moneys or other property payable or
      deliverable on any such claims and to distribute the same; and any
      receiver, assignee, trustee, custodian, liquidator, sequestrator (or other
      similar official) in any such proceeding is hereby authorized by each such
      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 such
      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
      6.7.

      Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Holder any plan of
reorganization, arrangement, adjustment or composition affecting the Debt
Securities and any Coupons of such series 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 5.5. TRUSTEE MAY ENFORCE CLAIMS WITHOUT POSSESSION OF DEBT
SECURITIES.

      All rights of action and claims under this Indenture or the Debt
Securities and the Coupons, if any, of any series may be prosecuted and enforced
by the Trustee without the possession of any of such 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 or Coupons in respect of which such judgment
has been recovered.

                                       46

      SECTION 5.6. APPLICATION OF MONEY COLLECTED.

      Subject to Article XVIII, any money collected by the Trustee pursuant to
this Article V 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 Coupons of any series in respect of which money has been collected
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
      6.7.

            SECOND: To the payment of all Senior Indebtedness if and to the
      extent required by Article XVIII.

            THIRD: To the payment of the amounts then due and unpaid for
      principal of (and premium, if any) and interest on the Debt Securities or
      Coupons of such series, 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
      or Coupons for principal (and premium, if any) and interest, respectively;
      and

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

      SECTION 5.7. LIMITATION ON SUITS.

      No Holder of any Debt Security or Coupon of any series shall have any
right to institute any action or proceeding, judicial or otherwise, at law or in
equity or in bankruptcy or otherwise with respect to this Indenture, or for the
appointment of a receiver, trustee, liquidator, custodian sequestrator (or other
similar official) or for any other remedy hereunder, unless

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

                                       47
<PAGE>

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 of the Holders of Outstanding Debt Securities or Coupons of any other
series, or to obtain or to seek to obtain priority or preference over any other
of such Holders or to enforce any right under this Indenture, except in the
manner herein provided and for the equal and ratable benefit of all of such
Holders. For the protection and enforcement of the provisions of this Section
5.7, each and every Holder of Debt Securities or Coupons of any series and the
Trustee for such series shall be entitled to such relief as can be given at law
or in equity.

      SECTION 5.8. UNCONDITIONAL RIGHT OF HOLDERS TO RECEIVE PRINCIPAL, PREMIUM
AND INTEREST.

      Notwithstanding any other provision in this Indenture, the Holder of any
Debt Security or of any 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 3.7) interest on such Debt Security or Coupon on the
respective Stated Maturity or Maturities expressed in such Debt Security or
Coupon (or, in the case of redemption, on the Redemption Date) and to institute
suit for the enforcement of any such payment and interest thereon, and such
right shall not be impaired without the consent of such Holder.

      SECTION 5.9. RESTORATION OF RIGHTS AND REMEDIES.

      If the Trustee or any Holder has instituted any proceeding to enforce any
right or remedy under this Indenture and such proceeding has been discontinued
or abandoned for any reason, or has been determined adversely to the Trustee or
to such Holder, then and in every such case the Company, the Trustee and the
Holders shall, subject to any determination in such proceeding, be restored
severally and respectively to their former positions and rights hereunder, and
thereafter all rights and remedies of the Company, Trustee and the Holders shall
continue as though no such proceeding had been instituted.

      SECTION 5.10. RIGHTS AND REMEDIES CUMULATIVE.

      Except as otherwise expressly provided elsewhere in this Indenture, 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 5.11. DELAY OR OMISSION NOT WAIVER.

      No delay or omission of the Trustee or of any Holder 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 any acquiescence
therein. Every right and remedy given by this Indenture 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.

                                       48
<PAGE>

      SECTION 5.12. CONTROL BY HOLDERS.

      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 by this Indenture 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 6.1, 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 proceeding so directed would be unjustly
      prejudicial to the Holders of Debt Securities of such series not joining
      in any such direction; and

            (3) the Trustee may take any other action deemed proper by the
      Trustee which is not inconsistent with such direction.

      SECTION 5.13. WAIVER OF PAST DEFAULTS.

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

            (1) in the payment of the principal of (or premium, if any) or
      interest on any Debt Security of such series, or in the payment of any
      sinking fund installment or analogous obligation with respect to the Debt
      Securities of such series; or

            (2) in respect of a covenant or provision hereof which pursuant to
      Article XI cannot be modified or amended without the consent of the Holder
      of each Outstanding Debt Security of such series affected; provided that a
      majority in principal amount of the Outstanding Debt Securities of a given
      series may rescind and annul a declaration of acceleration with respect to
      Debt Securities of such series as provided in Section 5.2.

      Upon any such waiver, such default shall cease to exist, and any Event of
Default arising therefrom shall be deemed to have been cured and not to have
occurred, for every purpose of the Debt Securities of such series under this
Indenture, but no such waiver shall extend to any subsequent or other default or
impair any right consequent thereon.

      SECTION 5.14. UNDERTAKING FOR COSTS.

      All parties to this Indenture agree, and each Holder of any Debt Security
or any 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

                                       49
<PAGE>

against the Trustee for any action taken, suffered or omitted by it as Trustee,
the filing by any party litigant in such suit other than the Trustee of an
undertaking to pay the costs of such suit, and that such court may in its
discretion assess reasonable costs, including reasonable attorneys' fees,
against any party litigant in such suit, having due regard to the merits and
good faith of the claims or defenses made by such party litigant, but the
provisions of this Section shall not apply to any suit instituted by the
Company, to any suit instituted by the Trustee, to any suit instituted by any
Holder or group of Holders holding in the aggregate more than 10% in principal
amount of the Outstanding Debt Securities of any series, or to any suit
instituted by any Holder of a Debt Security or Coupon for the enforcement of the
payment of the principal of (or premium, if any) or interest on such Debt
Security or the payment of any Coupon on or after the respective Stated Maturity
or Maturities expressed in such Debt Security or Coupon (or, in the case of
redemption, on or after the Redemption Date).

      SECTION 5.15. 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 wherever enacted,
now or at any time hereafter in force, which may affect the covenants or the
performance of this Indenture; and the Company (to the extent that it may
lawfully do so) hereby expressly waives all benefit or advantage of any such
law, and covenants that it will not hinder, delay or impede the execution of any
power herein granted to the Trustee, but will suffer and permit the execution of
every such power as though no such law had been enacted.

                                   ARTICLE VI.

                                   THE TRUSTEE

      SECTION 6.1. CERTAIN DUTIES AND RESPONSIBILITIES.

      (a) Except during the continuance of an Event of Default with respect to
the Debt Securities of any series:

            (1) the Trustee undertakes to perform such duties and only such
      duties as are specifically set forth in this Indenture, and no implied
      covenants or obligations shall be read into this Indenture against the
      Trustee; and

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

      (b) In case an Event of Default with respect to Debt Securities of any
series has occurred and is continuing, the Trustee shall, with respect to the
Debt Securities of such series, exercise such of the rights and powers vested in
it by this Indenture, and use the same degree of

                                       50
<PAGE>

care and skill in their exercise, as a prudent man would exercise or use under
the circumstances in the conduct of his own affairs.

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

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

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

            (3) the Trustee shall not be liable with respect to any action
      taken, suffered or omitted to be taken by it with respect to Debt
      Securities of any series in good faith in accordance with the direction of
      the Holders of a majority in principal amount of the Outstanding Debt
      Securities of such series relating to the time, method and place of
      conducting any proceeding for any remedy available to the Trustee, or
      exercising any trust or power conferred upon the Trustee, under this
      Indenture;

            (4) the Trustee is under no obligation or duty to pay interest on or
      invest any funds deposited with it except as specifically provided in this
      Indenture, and all investment activities undertaken by the Trustee, if
      any, shall be at and pursuant to the written instruction of the Company;
      and

            (5) the Trustee shall not be required 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.

      (d) 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.

      (e) Any opinion required or permitted to be delivered to the Trustee
hereunder may be addressed and delivered to the entity serving as Trustee
hereunder solely in its individual capacity and not in its capacity as Trustee,
fiduciary or as representative of the holders of such Debt Securities and
Coupons issued by the Company.

      SECTION 6.2. NOTICE OF DEFAULTS.

      Within 90 days after the occurrence of any default hereunder with respect
to Debt Securities or Coupons, if any, of any series, the Trustee shall give
notice to all Holders of Debt Securities and Coupons of such series of such
default hereunder known to the Trustee, unless such default shall have been
cured or waived; provided, however, that, except in the case of a

                                       51
<PAGE>

default in the payment of the principal of (or premium, if any) or interest on
any Debt Security or Coupon of such series or in the payment of any sinking fund
installment with respect to Debt Securities of such series, the Trustee shall be
protected in withholding such notice if and so long as the board of directors,
the executive committee or a trust committee of directors and/or Responsible
Officers of the Trustee in good faith determine that the withholding of such
notice is in the interest of the Holders of Debt Securities and of Coupons of
such series; and provided, further, that in the case of any default of the
character specified in Section 5.1(4) with respect to Debt Securities of such
series no such notice to Holders shall be given until at least 90 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.

      Notice given pursuant to this Section 6.2 shall be transmitted by mail:

            (1) to all Registered Holders, as the names and addresses of the
      Registered Holders appear in the Security Register;

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

<PAGE>

      (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 any series pursuant to this Indenture, unless
such Holders shall have offered to the Trustee reasonable security or indemnity
against the costs, expenses and liabilities which might be incurred by it in
compliance with such request or direction;

      (f) the Trustee shall not be bound to make any investigation into the

majority of the Holders of the Outstanding Debt Securities affected thereby, 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; 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 (including any agent appointed pursuant to
Section 3.10(j)) or attorney appointed with due care by it hereunder.

      SECTION 6.4. NOT RESPONSIBLE FOR RECITALS OR ISSUANCE OF DEBT SECURITIES.

      SECTION 6.5. MAY HOLD DEBT SECURITIES.

      The Trustee, any Paying Agent, the Security Registrar or any other agent
of the Company, in its individual or any other capacity, may become the owner or
pledgee of Debt Securities or Coupons, and, subject to Sections 6.8 and 6.13,
may otherwise deal with the Company with the same rights it would have if it
were not Trustee, Paying Agent, Security Registrar or such other agent.

      SECTION 6.6. MONEY HELD IN TRUST.

      Money in any Currency 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

agreed with the Company or (ii) losses resulting from currency fluctuations or
any investments made pursuant to 6.1(c)(4).

      SECTION 6.7. COMPENSATION AND REIMBURSEMENT.

      The Company agrees:

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

            (2) except as otherwise expressly provided herein, to reimburse the
      trustee in Dollars 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 to the extent of any such expense, disbursement or
      advance as may be attributable to its negligence, bad faith or willful
      misconduct; and

            (3) to indemnify in Dollars 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, except to the extent that any such
      claim or liability may be attributable to the Trustee's negligence, bad
      faith or willful misconduct.

      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
Coupons, if any, upon all property and funds held or collected by the Trustee as
such, except funds held in trust for the payment of amounts due on the Debt
Securities and Coupons.

      The obligations of the Company under this Section 6.7 to compensate and
indemnify the Trustee for expenses, disbursements and advances shall constitute
additional indebtedness under this Indenture and shall survive the satisfaction
and discharge of this Indenture.

      SECTION 6.8. DISQUALIFICATION; CONFLICTING INTERESTS.

      (a) If the Trustee has or shall acquire any conflicting interest, as
defined in this Section 6.8 with respect to the Debt Securities of any series,
then, within 90 days after ascertaining that it has such conflicting interest,
and if the default (as hereinafter defined) to which such conflicting interest
relates has not been cured or duly waived or otherwise eliminated before the end
of such 90-day period, the Trustee shall either eliminate such conflicting
interest or, except as otherwise provided below, resign with respect to the Debt
Securities of such series, and the Company shall take prompt steps to have a
successor appointed, in the manner and with the effect hereinafter specified in
this Article VI.

      (b) In the event that the Trustee shall fail to comply with the provisions
of subsection (a) of this Section with respect to the Debt Securities of any
series, the Trustee shall, within 10

                                       54
<PAGE>

days after the expiration of such 90-day period, transmit to all Holders of Debt
Securities of such series notice of such failure.

      Notice given pursuant to this Section 6.8(b) shall be transmitted by mail:

            (1) to all Registered Holders, as the names and addresses of the
      Registered Holders appear in the Security Register;

            (2) to such Holders of Bearer Securities of any series as have,
      within two years preceding such transmission, filed their names and
      addresses with the Trustee for such series for that purpose; and

            (3) to each Holder of a Debt Security of any series whose name and
      address appear in the information preserved at the time by the Trustee in
      accordance with Section 7.2(a) of this Indenture.

      (c) For the purposes of this Section, the Trustee shall be deemed to have
a conflicting interest with respect to the Debt Securities of any series, if
there shall exist an Event of Default (as such term is defined herein, but
exclusive of any period of grace or requirement of notice) with respect to such
Debt Securities and:

            (1) the Trustee is trustee under this Indenture with respect to the
      Outstanding Debt Securities of any series other than that series or is
      trustee under another indenture under which any other securities, or
      certificates of interest or participation in any other securities, of the
      Company are outstanding, unless such other indenture is a collateral trust
      indenture under which the only collateral consists of Debt Securities
      issued under this Indenture, provided that there shall be excluded from
      the operation of this paragraph this Indenture with respect to the Debt
      Securities of any series other than that series and any other indenture or
      indentures under which other securities, or certificates of interest or
      participation in other securities, of the Company are outstanding, if

                  (i) this Indenture and such other indenture or indentures (and
            all series of securities issuable thereunder) are wholly unsecured
            and rank equally and such other indenture or indentures are
            hereafter qualified under the Trust Indenture Act, unless the
            Commission shall have found and declared by order pursuant to
            Section 305(b) or Section 307(c) of the Trust Indenture Act that
            differences exist between the provisions of this Indenture with
            respect to the Debt Securities of such series and one or more other
            series or the provisions of such other indenture or indentures which
            are so likely to involve a material conflict of interest as to make
            it necessary, in the public interest or for the protection of
            investors to disqualify the Trustee from acting as such under this
            Indenture with respect to the Debt Securities of such series and
            such other series or under such other indenture or indentures, or

                  (ii) the Company shall have sustained the burden of proving,
            on application to the Commission and after opportunity for hearing

                                       55
<PAGE>

            thereon, that trusteeship under this Indenture with respect to the
            Debt Securities of such series and such other series or such other
            indenture or indentures is not so likely to involve a material
            conflict of interest as to make it necessary in the public interest
            or for the protection of investors to disqualify the Trustee from
            acting as such under this Indenture with respect to the Debt
            Securities of such series and such other series or under such other
            indenture or indentures;

            (2) the Trustee or any of its directors or executive officers is an
      underwriter for the Company;

            (3) the Trustee directly or indirectly controls or is directly or
      indirectly controlled by or is under direct or indirect common control
      with an underwriter for the Company;

            (4) the Trustee or any of its directors or executive officers is a
      director, officer, partner, employee, appointee or representative of the
      Company, or of an underwriter (other than the Trustee itself) for the
      Company who is currently engaged in the business of underwriting, except
      that (i) one individual may be a director or an executive officer, or
      both, of the Trustee and a director or an executive officer, or both, of
      the Company but may not be at the same time an executive officer of both
      the Trustee and the Company; (ii) if and so long as the number of
      directors of the Trustee in office is more than nine, one additional
      individual may be a director or an executive officer, or both, of the
      Trustee and a director of the Company; and (iii) the Trustee may be
      designated by the Company or by any underwriter for the Company to act in
      the capacity of transfer agent, registrar, custodian, paying agent, fiscal
      agent, escrow agent, or depositary or in any other similar capacity, or,
      subject to the provisions of paragraph (l) of this subsection, to act as
      trustee, whether under an indenture or otherwise;

            (5) 10% or more of the voting securities of the Trustee is
      beneficially owned either by the Company or by any director, partner or
      executive officer thereof, or 20% or more of such voting securities is
      beneficially owned, collectively, by any two or more of such persons; or
      10% or more of the voting securities of the Trustee is beneficially owned
      either by an underwriter for the Company or by any director, partner or
      executive officer thereof or is beneficially owned, collectively, by any
      two or more such persons;

            (6) the Trustee is the beneficial owner of, or holds as collateral
      security for an obligation which is in default (as hereinafter in this
      subsection defined), (i) 5% or more of the voting securities, or 10% or
      more of any other class of security, of the Company not including the Debt
      Securities issued under this Indenture and securities issued under any
      other indenture under which the Trustee is also trustee, or (ii) 10% or
      more of any class of security of an underwriter for the Company;

                                       56
<PAGE>

            (7) the Trustee is the beneficial owner of or holds as collateral
      security for an obligation which is in default, 5% or more of the voting
      securities of any person who, to the knowledge of the Trustee, owns 10% or
      more of the voting securities of, or controls directly or indirectly or is
      under direct or indirect common control with, the Company;

            (8) the Trustee is the beneficial owner of or holds as collateral
      security for an obligation which is in default, 10% or more of any class
      of security of any person who, to the knowledge of the Trustee, owns 50%
      or more of the voting securities of the Company;

            (9) the Trustee owns, on the date of such Event of Default or any
      anniversary of such Event of Default while such Event of Default remains
      outstanding, in the capacity of executor, administrator, testamentary or
      inter vivos trustee, guardian, committee or conservator, or in any other
      similar capacity, an aggregate of 25% or more of the voting securities, or
      of any class of security, of any person, the beneficial ownership of a
      specified percentage of which would have constituted a conflicting
      interest under paragraph (6), (7) or (8) of this subsection. As to any
      such securities of which the Trustee acquired ownership through becoming
      executor, administrator or testamentary trustee of an estate which
      included them, the provisions of the preceding sentence shall not apply,
      for a period of not more than two years from the date of such acquisition,
      to the extent that such securities included in such estate do not exceed
      25% of such voting securities or 25% of any such class of security.
      Promptly after the dates of any such Event of Default and annually in each
      succeeding year that such Event of Default continues, the Trustee shall
      make a check of its holdings of such securities in any of the
      above-mentioned capacities as of such dates. If the Company fails to make
      payment in full of the principal of (or premium, if any) or interest on
      any of the Debt Securities when and as the same becomes due and payable,
      and such failure continues for 30 days thereafter, the Trustee shall make
      a prompt check of its holdings of such securities in any of the
      above-mentioned capacities as of the date of the expiration of such 30-day
      period, and after such date, notwithstanding the foregoing provisions of
      this paragraph, all such securities so held by the Trustee, with sole or
      joint control over such securities vested in it, shall be considered as
      though beneficially owned by the Trustee for the purposes of paragraphs
      (6), (7) and (8) of this subsection; or

            (10) except under the circumstances described in paragraphs (1),
      (3), (4), (5) or (6) of Section 6.13(b) of this Indenture, the Trustee
      shall be or shall become a creditor of the Company.

      For the purposes of paragraph (1) of this subsection, the term "series of
securities" or "series" means a series, class or group of securities issuable
under an indenture pursuant to whose terms holders of one such series may vote
to direct the Trustee, or otherwise take action pursuant to a vote of such
holders, separately from holders of another series; provided, that "series of
securities" or "series" shall not include any series of securities issuable
under an indenture if all such series rank equally and are wholly unsecured.

                                       57
<PAGE>

      The specification of percentages in paragraphs (5) to (9), inclusive, of
this subsection shall not be construed as indicating that the ownership of such
percentages of the securities of a person is or is not necessary or sufficient
to constitute direct or indirect control for the purposes of paragraph (3) or
(7) of this subsection.

      For the purposes of paragraphs (6), (7), (8) and (9) of this subsection
only, (i) the terms "security" and "securities" shall include only such
securities as are generally known as corporate securities, but shall not include
any note or other evidence of indebtedness issued to evidence an obligation to
repay moneys lent to a person by one or more banks, trust companies or banking
firms, or any certificate of interest or participation in any such note or
evidence of indebtedness; (ii) an obligation shall be deemed to be "in default"
when a default in payment of principal shall have continued for 30 days or more
and shall not have been cured; and (iii) the Trustee shall not be deemed to be
the owner or holder of (A) any security which it holds as collateral security,
as trustee or otherwise, for an obligation which is not in default as defined in
clause (ii) above, or (B) any security which it holds as collateral security
under this Indenture, irrespective of any default hereunder, or (C) any security
which it holds as agent for collection, or as custodian, escrow agent or
depositary, or in any similar representative capacity.

      (d) For the purposes of this Section:

            (1) The term "underwriter" when used with reference to the Company
      means every person who, within one year prior to the time as of which the
      determination is made, has purchased from the Company with a view to, or
      has offered or sold for the Company in connection with, the distribution
      of any security of the Company outstanding at such time, or has
      participated or has had a direct or indirect participation in any such
      undertaking, or has participated or has had a participation in the direct
      or indirect underwriting of any such undertaking, but such term shall not
      include a person whose interest was limited to a commission from an
      underwriter or dealer not in excess of the usual and customary
      distributors' or sellers' commission.

            (2) The term "director" means any director of a corporation, or any
      individual performing similar functions with respect to any organization
      whether incorporated or unincorporated.

            (3) The term "person" means an individual, a corporation, a
      partnership, an association, a joint stock company, a trust, an estate, an
      unincorporated organization, or a government or political subdivision
      thereof. As used in this paragraph, the term "trust" shall include only a
      trust where the interest or interests of the beneficiary or beneficiaries
      are evidenced by a security.

            (4) The term "voting security" means any security presently
      entitling the owner or holder thereof to vote in the direction or
      management of the affairs of a person, or any security issued under or
      pursuant to any trust, agreement or arrangements whereby a trustee or
      trustees or agent or agents for the owner or holder of such security are
      presently entitled to vote in the direction or management of the affairs
      of a person.

                                       58
<PAGE>

            (5) The term "Company" means any obligor upon the Debt Securities of
      any series.

            (6) The term "executive officer" means the president, every vice
      president, every trust officer, the cashier, the secretary, and the
      treasurer of a corporation, and any individual customarily performing
      similar functions with respect to any organization, whether incorporated
      or unincorporated, but shall not include the chairman of the board of
      directors.

      (e) The percentages of voting securities and other securities specified in
this Section shall be calculated in accordance with the following provisions:

            (1) A specified percentage of the voting securities of the Trustee,
      the Company or any other person referred to in this Section (each of whom
      is referred to as a "person" in this paragraph) means such amount of the
      outstanding voting securities of such person as entitles the holder or
      holders thereof to cast such specified percentage of the aggregate votes
      which the holders of all the outstanding voting securities of such person
      are entitled to cast in the direction or management of the affairs of such
      person.

            (2) A specified percentage of a class of securities of a person
      means such percentage of the aggregate amount of securities of the class
      outstanding.

            (3) The term "amount," when used with regard to securities means the
      principal amount if relating to evidences of indebtedness, the number of
      shares if relating to capital shares, and the number of units if relating
      to any other kind of security.

            (4) The term "outstanding" means issued and not held by or for the
      account of the issuer. The following securities shall not be deemed
      outstanding within the meaning of this definition:

                  (i) securities of an issuer held in a sinking fund relating to
            securities of the issuer of the same class;

                  (ii) securities of an issuer held in a sinking fund relating
            to another class of securities of the issuer, if the obligation
            evidenced by such other class of securities is not in default as to
            principal or interest or otherwise;

                  (iii) securities pledged by the issuer thereof as security for
            an obligation of the issuer not in default as to principal or
            interest or otherwise; and

                  (iv) securities held in escrow if placed in escrow by the
            issuer thereof;

                                       59
<PAGE>

      provided, however, that any voting securities of an issuer shall be deemed
      outstanding if any person other than the issuer is entitled to exercise
      the voting rights thereof.

            (5) A security shall be deemed to be of the same class as another
      security if both securities confer upon the holder or holders thereof
      substantially the same rights and privileges; provided, however, that, in
      the case of secured evidences of indebtedness, all of which are issued
      under a single indenture, differences in the interest rates or maturity
      dates of various series thereof shall not be deemed sufficient to
      constitute such series different classes; and provided, further, that, in
      the case of unsecured evidences of indebtedness, differences in the
      interest rates or maturity dates thereof shall not be deemed sufficient to
      constitute them securities of different classes, whether or not they are
      issued under a single indenture. Nothing in the forgoing shall in anyway
      whatsoever affect whether a security shall be deemed to be of the same
      class as another security for purposes of Section 13 of the Securities
      Exchange Act of 1934 and Rule 13a-3 thereunder or otherwise under federal
      securities laws.

      (f) Except in the case of a default in the payment of the principal of or
interest on any Debt Security of any series, or in the payment of any sinking or
purchase fund installment, the Trustee shall not be required to resign as
provided by this Section if the Trustee shall have sustained the burden of
proving, on application to the Commission and after opportunity for hearing
thereon, that:

            (1) the Event of Default may be cured or waived during a reasonable
      period and under the procedures described in such application; and

            (2) a stay of the Trustee's duty to resign will not be inconsistent
      with the interests of Holders of the Debt Securities.

The filing of such an application shall automatically stay the performance of
the duty to resign until the Commission orders otherwise.

      SECTION 6.9. CORPORATE TRUSTEE REQUIRED; ELIGIBILITY.

      There shall at all times be a Trustee hereunder which shall be a
corporation organized and doing business under the laws of the United States of
America, any State thereof or the District of Columbia, authorized under such
laws to exercise corporate trust powers, having a combined capital and surplus
of at least $75,000,000, subject to supervision or examination by Federal, State
or District of Columbia authority. 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. Neither the Company nor any person directly or
indirectly controlling, controlled by, or under common control with the Company
shall serve as Trustee upon any Debt Securities.

                                       60

      SECTION 6.10. RESIGNATION AND REMOVAL; APPOINTMENT OF SUCCESSOR.

      (a) No resignation or removal of the Trustee and no appointment of a
successor Trustee pursuant to this Article VI shall become effective until the
acceptance of appointment by the successor Trustee under Section 6.11.

      (b) The Trustee may resign at any time with respect to the 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.

      (c) The Trustee may be removed at any time with respect to the Debt
Securities of any series and a successor Trustee appointed 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 6.8(a) 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 6.9 with
      respect to the Debt Securities of any series and shall fail to resign
      after written request therefor by the Company or by any such Holder, or

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

then, in any such case, (i) the Company by a Board Resolution may remove the
Trustee with respect to all Debt Securities, or (ii) subject to Section 5.14,
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 and
the appointment of a successor Trustee for the Debt Securities of such series.

      (e) If the Trustee shall resign, be removed or become incapable of acting,
or if a vacancy shall occur in the office of Trustee for any cause, with respect
to the Debt Securities of 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 6.11. If, within one year
after such resignation, removal or incapability, or the occurrence of such
vacancy, a successor Trustee with respect to the Debt Securities of any series

                                       61
<PAGE>

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 of such series 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 5.14, 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 in the manner and to the extent provided in Section 1.5 to the Holders of
Debt Securities of such series. 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 6.11. ACCEPTANCE OF APPOINTMENT BY SUCCESSOR.

      (a) In the case of an appointment hereunder of a successor Trustee with
respect to all Debt Securities, each 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, subject nevertheless to its
claim, if any, provided for in Section 6.7.

      (b) In 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 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 any

                                       62
<PAGE>

such supplemental indenture shall constitute such Trustees co-trustees of the
same trust and that each such Trustee shall be trustee of a trust or trusts
hereunder separate and apart from any other trust or trusts hereunder
administered by any other such Trustee; and upon the execution and delivery of
any 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 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 6.11, 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 VI.

      SECTION 6.12. MERGER, CONVERSION, CONSOLIDATION OR SUCCESSION TO BUSINESS.

      Any corporation into which the Trustee may be merged or converted or with
which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the trustee shall be a party, or any
corporation succeeding to all or substantially all of the corporate trust
business of the Trustee, shall be the successor of the Trustee hereunder,
provided that such corporation shall be otherwise qualified and eligible under
this Article VI, without the execution 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 or consolidation 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.

      SECTION 6.13. PREFERENTIAL COLLECTION OF CLAIMS AGAINST COMPANY.

      (a) Subject to subsection (b) of this Section 6.13, if the Trustee shall
be or shall become a creditor, directly or indirectly, secured or unsecured, of
the Company within three months prior to a default, as defined in subsection (c)
of this Section 6.13, or subsequent to such default, then, unless and until such
default shall be cured, the Trustee shall set apart and hold in a special
account for the benefit of the Trustee individually, the Holders of the Debt
Securities and of the Coupons, if any, and the holders of other indenture
securities (as defined in subsection (c) of this Section 6.13):

                                       63
<PAGE>

            (1) an amount equal to any and all reductions in the amount due and
      owing upon any claim as such creditor in respect of principal or interest,
      effected after the beginning of such three-month period and valid as
      against the Company and its other creditors, except any such reduction
      resulting from the receipt or disposition of any property described in
      paragraph (2) of this subsection, or from the exercise of any right of
      set-off which the Trustee could have exercised if a voluntary or
      involuntary case had been commenced in respect of the Company under the
      Federal bankruptcy laws, as now or hereafter constituted, or any other
      applicable Federal or State bankruptcy, insolvency or other similar law
      upon the date of such default; and

            (2) all property received by the Trustee in respect of any claim as
      such creditor, either as security therefor, or in satisfaction or
      composition thereof, or otherwise, after the beginning of such three-month
      period, or an amount equal to the proceeds of any such property, if
      disposed of, subject, however, to the rights, if any, of the Company and
      its other creditors in such property or such proceeds.

Nothing herein contained, however, shall affect the right of the Trustee:

            (A) to retain for its own account (i) payments made on account of
      any such claim by any Person (other than the Company) who is liable
      thereon, and (ii) the proceeds of the bona fide sale of any such claim by
      the Trustee to a third Person, and (iii) distributions made in cash,
      securities or other property in respect of claims filed against the
      Company in bankruptcy or receivership or in proceedings or reorganization
      pursuant to the Federal bankruptcy laws, as now or hereafter constituted,
      or any other applicable Federal or State bankruptcy, insolvency or other
      similar law;

            (B) to realize, for its own account, upon any property held by it as
      security for any such claim, if such property was so held prior to the
      beginning of such three-month period;

            (C) to realize, for its own account, but only to the extent of the
      claim hereinafter mentioned, upon any property held by it as security for
      any such claim, if such claim was created after the beginning of such
      three-month period and such property was received as security therefor
      simultaneously with the creation thereof, and if the Trustee shall sustain
      the burden of proving that at the time such property was so received the
      Trustee had no reasonable cause to believe that a default, as defined in
      subsection (c) of this Section, would occur within three months; or

            (D) to receive payment on any claim referred to in paragraph (B) or
      (C) against the release of any property held as security for such claim as
      provided in paragraph (B) or (C), as the case may be, to the extent of the
      fair value of such property.

                                       64
<PAGE>

      For the purposes of paragraphs (B), (C) and (D), property substituted
after the beginning of such three-month period for property held as security at
the time of such substitution shall, to the extent of the fair value of the
property released, have the same status as the property released, and, to the
extent that any claim referred to in any of such paragraphs is created in
renewal of or in substitution for or for the purpose of repaying or refunding
any pre-existing claim of the Trustee as such creditor, such claim shall have
the same status as such pre-existing claim.

      If the Trustee shall be required to account, the funds and property held
in such special account and the proceeds thereof shall be apportioned among the
Trustee, the Holders and the holders of other indenture securities in such
manner that the Trustee, the Holders and the holders of other indenture
securities realize, as a result of payments from such special account and
payments of dividends on claims filed against the Company in bankruptcy or
receivership or in proceedings for reorganization pursuant to the Federal
bankruptcy laws, as now or hereafter constituted or any other applicable Federal
or State bankruptcy, insolvency or other similar law, the same percentage of
their respective claims, figured before crediting to the claim of the Trustee
anything on account of the receipt by it from the Company of the funds and
property in such special account and before crediting to the respective claims
of the Trustee and the Holders and the holders of other indenture securities
dividends on claims filed against the Company in bankruptcy or receivership or
in proceedings for reorganization pursuant to the Federal bankruptcy laws, as
now or hereafter constituted, or any other applicable Federal or State
bankruptcy, insolvency or other similar law, but after crediting thereon
receipts on account of the indebtedness represented by their respective claims
from all sources other than from such dividends and from the funds and property
so held in such special account. As used in this paragraph, with respect to any
claim, the term "dividends" shall include any distribution with respect to such
claim, in bankruptcy or receivership or in proceedings for reorganization
pursuant to the Federal bankruptcy laws, as now or hereafter constituted, or any
other applicable Federal or State bankruptcy, insolvency or other similar law,
whether such distribution is made in cash, securities, or other property, but
shall not include any such distribution with respect to the secured portion, if
any, of such claim. The court in which such bankruptcy, receivership or
proceedings for reorganization is pending shall have jurisdiction (i) to
apportion among the Trustee and the Holders and the holders of other indenture
securities, in accordance with the provisions of this paragraph, the funds and
property held in such special account and proceeds thereof, or (ii) in lieu of
such apportionment, in whole or in part, to give to the provisions of this
paragraph due consideration in determining the fairness of the distributions to
be made to the Trustee and the Holders and the holders of other indenture
securities with respect to their respective claims, in which event it shall not
be necessary to liquidate or to appraise the value of any securities or other
property held in such special account or as security for any such claim, or to
make a specific allocation of such distributions as between the secured and
unsecured portions of such claim, or otherwise to apply the provisions of this
paragraph as a mathematical formula.

      Any Trustee which has resigned or been removed after the beginning of such
three-month period shall be subject to the provisions of this subsection as
though such resignation or removal had not occurred. If any Trustee has resigned
or been removed prior to the beginning of such three-month period, it shall be
subject to the provisions of this subsection if and only if the following
conditions exist:

                                       65
<PAGE>

            (i) the receipt of property or reduction of claim, which would have
      given rise to the obligation to account, if such Trustee had continued as
      Trustee, occurred after the beginning of such three-month period; and

            (ii) such receipt of property or reduction of claim occurred within
      three months after such resignation or removal.

      (b) There shall be excluded from the operation of subsection (a) of this
Section 6.13 a creditor relationship arising from:

            (1) the ownership or acquisition of securities issued under any
      indenture, or any security or securities having a maturity of one year or
      more at the time of acquisition by the Trustee;

            (2) advances authorized by a receivership or bankruptcy court of
      competent jurisdiction or by this Indenture, for the purpose of preserving
      any property which shall at any time be subject to this Indenture or of
      discharging tax liens or other prior liens or encumbrances thereon, if
      notice of such advances and of the circumstances surrounding the making
      thereof is given to the Holders at the time and in the manner provided in
      this Indenture;

            (3) disbursements made in the ordinary course of business in the
      capacity of trustee under an indenture, transfer agent, registrar,
      custodian, paying agent, fiscal agent or depositary, or other similar
      capacity;

            (4) an indebtedness created as a result of services rendered or
      premises rented, or an indebtedness created as a result of goods or
      securities sold in a cash transaction as defined in subsection (c) of this
      Section 6.13;

            (5) the ownership of stock or of other securities of a corporation
      organized under the provisions of Section 25(a) of the Federal Reserve
      Act, as amended, which is directly or indirectly a creditor of the
      Company; and

            (6) The acquisition, ownership, acceptance or negotiation of any
      drafts, bills of exchange, acceptances or obligations which fall within
      the classification of self-liquidating paper as defined in subsection (c)
      of this Section 6.13.

      (c) for the purposes of this Section 6.13 only:

            (1) The term "default" means any failure to make payment in full of
      the principal of or interest on any of the Debt Securities or upon the
      other indenture securities when and as such principal or interest becomes
      due and payable.

            (2) The term "other indenture securities" means securities upon
      which the Company is an obligor outstanding under any other indenture (i)
      under which the Trustee is also trustee, (ii) which contains provisions
      substantially similar to

                                       66
<PAGE>

      the provisions of this Section 6.13, and (iii) under which a default
      exists at the time of the apportionment of the funds and property held in
      such special account.

            (3) The term "cash transaction" means any transaction in which full
      payment for goods or securities sold is made within seven days after
      delivery of the goods or securities in currency or in checks or other
      orders drawn upon banks or bankers and payable upon demand.

            (4) The term "self-liquidating paper" means any draft, bill of
      exchange, acceptance or obligation which is made, drawn, negotiated or
      incurred by the Company for the purpose of financing the purchase,
      processing, manufacturing, shipment, storage or sale of goods, wares or
      merchandise and which is secured by documents evidencing title to,
      possession of, or a lien upon the goods, wares or merchandise or the
      receivables or proceeds arising from the sale of the goods, wares or
      merchandise or the receivables or proceeds arising from the sale of the
      goods, wares or merchandise, previously constituting the security,
      provided the security is received by the Trustee simultaneously with the
      creation of the creditor relationship with the Company arising from the
      making, drawing, negotiating or incurring of the draft, bill of exchange,
      acceptance or obligation.

            (5) The term "Company" means any obligor upon the Debt Securities.

      SECTION 6.14. APPOINTMENT OF AUTHENTICATING AGENT.

      As long as any Debt Securities of a series remain Outstanding, upon a
Company Request, there shall be an authenticating agent (the "Authenticating
Agent") appointed, for such period as the Company shall elect, by the Trustee
for such series of Debt Securities to act as its agent on its behalf and subject
to its direction in connection with the authentication and delivery of each
series of Debt Securities for which it is serving as Trustee. Debt Securities of
each such series authenticated by such Authenticating Agent shall be entitled to
the benefits of this Indenture and shall be valid and obligatory for all
purposes as if authenticated by such Trustee. Wherever reference is made in this
Indenture to the authentication and delivery of Debt Securities of any series by
the Trustee for such series or to the Trustee's Certificate of Authentication,
such reference shall be deemed to include authentication and delivery on behalf
of the Trustee for such series by an Authenticating Agent for such series and a
Certificate of Authentication executed on behalf of such Trustee by such
Authenticating Agent, except that only the Trustee may authenticate Debt
Securities upon original issuance and pursuant to Section 3.6 hereof. Such
Authenticating Agent shall at all times be a corporation organized and doing
business under the laws of the United States of America or of any State,
authorized under such laws to exercise corporate trust powers, having a combined
capital and surplus of at least $10,000,000 and subject to supervision or
examination by Federal or State authority. If such Authenticating Agent
publishes reports of condition at least annually, pursuant to law or to the
requirements of said supervising or examining authority, then for purposes of
this Section, the combined capital and surplus of such Authenticating Agent
shall be deemed to be its combined capital and surplus as set forth in its most
recent report of condition so published. If at any time an Authenticating Agent
shall cease to be eligible in accordance with the provisions of this Section,
such

                                       67
<PAGE>

Authenticating Agent shall resign immediately in the manner and with the effect
specified in this Section.

      Any corporation into which any Authenticating Agent may be merged or
converted, or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which any Authenticating Agent
shall be a party, or any corporation succeeding to the corporate agency business
of any Authenticating Agent, shall continue to be the Authenticating Agent with
respect to all series of Debt Securities for which it served as Authenticating
Agent without the execution or filing of any paper or any further act on the
part of the Trustee for such series or such Authenticating Agent. Any
Authenticating Agent may at any time, and if it shall cease to be eligible
shall, resign by giving written notice of resignation to the applicable Trustee
and to the Company.

      Upon receiving such a notice of resignation or upon such a termination, or
in case at any time any Authenticating Agent shall cease to be eligible in
accordance with the provisions of this Section 6.14 with respect to one or more
or all series of Debt Securities, the Trustee for such series shall upon Company
Request appoint a successor Authenticating Agent, and the Company shall provide
notice of such appointment to all Holders of Debt Securities of such series in
the manner and to the extent provided in Section 1.5. Any successor
Authenticating Agent upon acceptance of its appointment hereunder shall become
vested with all rights, powers, duties and responsibilities of its predecessor
hereunder, with like effect as if originally named as Authenticating Agent
herein. The Trustee for the Debt Securities of such series agrees to pay to the
Authenticating Agent for such series from time to time reasonable compensation
for its services, and the Trustee shall be entitled to be reimbursed for such
payment, subject to the provisions of Section 6.7. The Authenticating Agent for
the Debt Securities of any series shall have no responsibility or liability for
any action taken by it as such at the direction of the Trustee for such series.

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

      This is one of the series of Debt Securities issued under the within
mentioned Indenture.

                                              As Trustee

                                              By: _____________________________
                                                   As Authenticating Agent

                                  ARTICLE VII.

                HOLDERS' LISTS AND REPORTS BY TRUSTEE AND COMPANY

      SECTION 7.1. COMPANY TO FURNISH TRUSTEE NAMES AND ADDRESSES OF HOLDERS.

      The Company will furnish or cause to be furnished to the Trustee with
respect to Registered Securities of each series for which it acts as Trustee:

      (a) semi-annually on a date not more than 15 days after each Regular
Record Date with respect to an Interest Payment Date, if any, for the Registered
Securities of such series (or on semi-annual dates in each year to be determined
pursuant to Section 3.1 if the Registered Securities of such series do not bear
interest), a list, in such form as the Trustee may reasonably require, of the
names and addresses of the Registered Holders as of the date 15 days next
preceding each such Regular Record Date (or such semi-annual dates, as the case
may be); and

      (b) at such other times as the Trustee may request in writing, within 30
days after the receipt by the Company of any such request, a list of similar
form and content as of a date not more than 15 days prior to the time such list
is furnished;

provided, however, that if and so long as the Trustee shall be the Security
Registrar for such series, no such list need be furnished.

      The Company shall also be required to furnish to the Trustee at all such
times set forth above all information in the possession or control of the
Company or any of its Paying Agents other than the Trustee as to the names and
addresses of the Holders of Bearer Securities of all series; provided, however,
that the Company shall have no obligation to investigate any matter relating to
any Holders of Bearer Securities of any series.

      SECTION 7.2. PRESERVATION OF INFORMATION, COMMUNICATION TO HOLDERS.

      (a) The Trustee shall preserve, in as current a form as is reasonably
practicable, all information as to the names and addresses of Holders contained
in the most recent list furnished to the Trustee as provided in Section 7.1
received by it in the capacity of Paying Agent (if so acting) hereunder, and
filed with it within the two preceding years pursuant to Section 7.3(c)(2).

      The Trustee may destroy any list furnished to it as provided in Section
7.1 upon receipt of a new list so furnished, destroy any information received by
it as Paying Agent (if so acting) hereunder upon delivering to itself as
Trustee, not earlier than 45 days after an Interest Payment Date, a list
containing the names and addresses of the Holders obtained from such information
since the delivery of the next previous list, if any, destroy any list delivered
to itself as Trustee which was compiled from information received by it as
Paying Agent (if so acting) hereunder upon the receipt of a new list so
delivered, and destroy not earlier than two years after filing, any information
filed with it pursuant to Section 7.3(c)(2).

      (b) If three or more Holders (hereinafter referred to as "applicants")
apply in writing to the Trustee, and furnish to the Trustee reasonable proof
that each such applicant has owned a Debt Security for a period of at least six
months preceding the date of such application, and such

                                       69
<PAGE>

application states that the applicants desire to communicate with other Holders
of Debt Securities of a particular series (in which case the applicants must
hold Debt Securities of such series) or with all Holders of Debt Securities with
respect to their rights under this Indenture or under the Debt Securities and is
accompanied by a copy of the form of proxy or other communication which such
applicants propose to transmit, then the Trustee shall, within five Business
Days after the receipt of such application, at its election, either

            (i) afford such applicants access to the information preserved at
      the time by the Trustee in accordance with Section 7.2(a), or

            (ii) inform such applicants as to the approximate number of Holders
      of Debt Securities of such series or of all Debt Securities, as the case
      may be, whose names and addresses appear in the information preserved at
      the time by the Trustee in accordance with Section 7.2(a), and as to the
      approximate cost of mailing to such Holders the form of proxy or other
      communication, specified in such application.

      If the Trustee shall elect not to afford such applicants access to such
information, the Trustee shall, upon written request of such applicants, mail to
the Holders of Debt Securities of such series or all Holders, as the case may
be, whose names and addresses appear in the information preserved at the time by
the Trustee in accordance with Section 7.2(a), a copy of the form of proxy or
other communication which is specified in such request, with reasonable
promptness after a tender to the Trustee of the material to be mailed and of
payment, or provision for the payment, of the reasonable expenses of mailing,
unless within five days after such tender, the Trustee shall mail to such
applicants and file with the Commission, together with a copy of the material to
be mailed, a written statement to the effect that, in the opinion of the
Trustee, such mailing would be contrary to the best interests of the Holders of
Debt Securities of such series or all Holders, as the case may be, or would be
in violation of applicable law. Such written statement shall specify the basis
of such opinion. If the Commission, after opportunity for a hearing upon the
objections specified in the written statement so filed, shall enter an order
refusing to sustain any of such objections or if after the entry of an order
sustaining one or more of such objections, the Commission shall find, after
notice and opportunity for hearing, that all the objections so sustained have
been met and shall enter an order so declaring, the Trustee shall mail copies of
such material to all such Holders with reasonable promptness after the entry of
such order and the renewal of such tender; otherwise the Trustee shall be
relieved of any obligation or duty to such applicants respecting their
application.

      (c) Every Holder of Debt Securities, by receiving and holding the same,
agrees with the Company and the Trustee that neither the Company nor the Trustee
shall be held accountable by reason of the disclosure of any such information as
to the names and addresses of the Holders in accordance with Section 7.2(b),
regardless of the source from which such information was derived, and that the
Trustee shall not be held accountable by reason of mailing of any material
pursuant to a request made under Section 7.2(b).

      SECTION 7.3. REPORTS BY TRUSTEE.

      (a) Within 60 days after January 15 of each year, commencing with the
later of January 15, 2006, or the first January 15 after the first issuance of
Debt Securities pursuant to this Indenture, the Trustee shall, to the extent
required by the Trust Indenture Act, transmit to all Holders of Debt Securities
of any series with respect to which it acts as Trustee, in the manner
hereinafter provided in this Section 7.3, a brief report dated such date with
respect to any of the following events which may have occurred within the
previous 12 months (but if no such event has occurred within such period no
report need be transmitted):

            (1) any change to its eligibility under Section 6.9 and its
      qualifications under Section 6.8;

            (2) the creation of or any material change to a relationship
      specified in paragraph (1) through (10) of Section 6.8(c) of this
      Indenture;

            (3) the character and amount of any advances (and if the Trustee

      regulations prescribe) which the Company may be required to file with the
      Commission pursuant to Section 13 or Section 15(d) of the Securities

      provided, however, that the Company shall not be obligated to file such
      reports with the Commission if the Commission does not permit such
      filings. The Company will in all cases, without cost to each recipient,
      provide copies of such information to the Holders of the Debt Securities
      of each series and, if they are not permitted to file such reports with
      the Commission, shall make available information to prospective purchasers
      and to securities analysts and broker-dealers upon their request;

            (2) file with the Trustee and the Commission, in accordance with
      rules and regulations prescribed from time to time by the Commission, such
      additional information, documents and reports with respect to compliance

                                 ARTICLE VIII.

                             CONCERNING THE HOLDERS

      SECTION 8.1. ACTS OF HOLDERS.

      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 or proxy duly appointed in
writing; and, except as herein otherwise expressly provided, such action shall
become effective when such instrument or instruments are delivered to the
Trustee, and, where it is hereby expressly required, to the Company. Such
instrument or instruments (and the action embodied therein and evidenced
thereby) are herein sometimes referred to as the "Act" of the Holders signing
such instrument or instruments. Whenever in this Indenture it is provided that
the Holders of a specified percentage in aggregate principal amount of the
Outstanding Debt Securities of any series may take any Act, the fact that the
Holders of such specified percentage have joined therein may be evidenced (a) by
the instrument or

                                       73
<PAGE>

instruments executed by Holders in person or by agent or proxy appointed in
writing, or (b) by the record of Holders voting in favor thereof at any meeting
of such Holders duly called and held in accordance with the provisions of
Article IX, or (c) by a combination of such instrument or instruments and any
such record of such a meeting of Holders.

      SECTION 8.2. PROOF OF OWNERSHIP; PROOF OF EXECUTION OF INSTRUMENTS BY
HOLDER.

      The ownership of Registered Securities of any series shall be proved by
the Security Register for such series or by a certificate of the Security
Registrar for such series.

      The ownership of Bearer Securities shall be proved by production of such
Bearer Securities or by a certificate executed by any bank or trust company,
which certificate shall be dated and shall state that on the date thereof a
Bearer Security bearing a specified identifying number or other mark was
deposited with or exhibited to the person executing such certificate by the
person named in such certificate, or by any other proof of possession reasonably
satisfactory to the Trustee. The holding by the person named in any such
certificate of any Bearer Security specified therein shall be presumed to
continue for a period of one year unless at the time of determination of such
holding (1) another certificate bearing a later date issued in respect of the
same Bearer Security shall be produced, (2) such Bearer Security shall be
produced by some other person, (3) such Bearer Security shall have been
registered on the Security Register, if, pursuant to Section 3.1, such Bearer
Security can be so registered, or (4) such Bearer Security shall have been
canceled or paid.

      Subject to the provisions of Sections 6.1, 6.3 and 9.5, proof of the
execution of a writing appointing an agent or proxy and of the execution of any
instrument by a Holder or his agent or proxy shall be sufficient and conclusive
in favor of the Trustee and the Company if made in the following manner:

      The fact and date of the execution by any such person of any instrument
may be proved by the certificate of any notary public or other officer
authorized to take acknowledgements of deeds, that the person executing such
instrument acknowledged to him the execution thereof, or by an affidavit of a
witness to such execution sworn to before any such notary or other such officer.
Where such execution is by an officer of a corporation or association or a
member of a partnership on behalf of such corporation, association or
partnership, as the case may be, or by any other person acting in a
representative capacity, such certificate or affidavit shall also constitute
sufficient proof of his authority.

      The record of any Holders' meeting shall be proved in the manner provided
in Section 9.6.

      The Trustee may in any instance require further proof with respect to any
of the matters referred to in this Section 8.2 so long as the request is a
reasonable one.

      SECTION 8.3. PERSONS DEEMED OWNERS.

      The Company, the Trustee and any agent of the Company or the Trustee may
treat the Person in whose name any Registered Security is registered as the
owner of such Registered Security for the purpose of receiving payment of the
principal of (and premium, if any) and

                                       74
<PAGE>

(subject to Section 3.7) interest, if any, 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 Holder of any
Bearer Security or of any Coupon as the absolute owner of such Bearer Security
or Coupon for the purposes of receiving payment thereof or on account thereof
and for all other 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. All payments
made to any Holder, or upon his order, shall be valid, and, to the extent of the
sum or sums paid, effectual to satisfy and discharge the liability for moneys
payable upon such Debt Security or Coupon.

      SECTION 8.4. REVOCATION OF CONSENTS; FUTURE HOLDERS BOUND.

      At any time prior to (but not after) the evidencing to the Trustee, as
provided in Section 8.1, of the taking of any Act by the Holders of the
percentage in aggregate principal amount of the Outstanding Debt Securities
specified in this Indenture in connection with such Act, any Holder of a Debt
Security the number, letter or other distinguishing symbol of which is shown by
the evidence to be included in such Debt Securities, the Holders of which have
consented to such Act, by filing written notice with the Trustee at the
Corporate Trust Office and upon proof of ownership as provided in Section 8.2,
may revoke such Act so far as it concerns such Debt Security. Except as
aforesaid, any such Act taken by the Holder of any Debt Security shall be
conclusive and binding upon such Holder and, subject to the provisions of
Section 5.8, upon all future Holders of such Debt Security and all past, present
and future Holders of Coupons, if any, appertaining thereto and of any Debt
Securities and Coupons issued on transfer or in lieu thereof or in exchange or
substitution therefor, irrespective of whether or not any notation in regard
thereto is made upon such Debt Security or Coupons or such other Debt Securities
or Coupons.

      of the Holders of any specified aggregate principal amount of the
      Outstanding Debt Securities of any one or more or all series, as the case
      may be, under any other provision of this Indenture or under applicable
      law.

      SECTION 9.2. CALL OF MEETINGS BY TRUSTEE.

      The Trustee for any series may at any time call a meeting of Holders of
such series to take any action specified in Section 9.1, to be held at such time
or times and at such place or places as the Trustee for such series shall
determine. Notice of every meeting of the Holders of any series, setting forth

such series by written request setting forth in reasonable detail the action
proposed to be taken at the meeting, and the Trustee shall not have given the
notice of such meeting within 10 days after the receipt of such request, then
the Company or such Holders may determine the time or times and the place or
places for such meetings and may call such meetings to take any action
authorized in Section 9.1, by giving notice thereof as provided in Section 9.2.

      SECTION 9.4. QUALIFICATIONS FOR VOTING.

      To be entitled to vote at any meeting of Holders a Person shall be (a) a
Holder of a Debt Security of the series with respect to which such meeting is

the appointment and duties of inspectors of votes, the submission and
examination of proxies, certificates and other evidence of the right to vote,
and such other matters concerning the conduct of the meeting as it shall deem
appropriate.

      The Trustee shall, by an instrument in writing, appoint a temporary

A permanent chairman and a permanent secretary of the meeting shall be elected
by a majority vote of the meeting.

      Subject to the provisos in the definition of "Outstanding," at any meeting
each Holder of a Debt Security of the series with respect to which such meeting

such series held by him or instruments in writing duly designating him as the
person to vote on behalf of Holders of Debt Securities of such series. Any
meeting of Holders with respect to which a meeting was duly called pursuant to

represented by them. The permanent chairman of the meeting shall appoint two
inspectors of votes who shall count all votes cast at the meeting for or against
any resolution and who shall make and file with the secretary of the meeting
their verified written reports in duplicate of all votes cast at the meeting. A
record in duplicate of the proceedings of each meeting of Holders shall be
taken, and there shall be attached to said record the original reports of the
inspectors of votes on any vote by ballot taken thereat and affidavits by one or
more persons having knowledge of the facts setting forth a copy of the notice of
the meeting and showing that said notice was transmitted as provided in Section

favor of or against any resolution. The record shall be signed and verified by
the affidavits of the permanent chairman and secretary of the meeting, and one
of the duplicates shall be delivered to the Company and the other to the Trustee
to be preserved by the Trustee.

      that would be due and payable upon a declaration of acceleration of the
      Maturity thereof pursuant to Section 5.2, or (f) reduce the amount of, or
      postpone the date fixed for, any payment under any sinking fund or
      analogous provisions for any Debt Security, or (g) impair the right to
      institute suit for the enforcement of any payment on or after the Stated
      Maturity thereof (or, in the case of redemption, on or after the
      Redemption Date), or (h) limit the obligation of the Company to maintain a
      paying agency outside the United States for payment on Bearer Securities
      as provided in Section 12.3, or (i) adversely affect the right to convert

            (3) reduce the percentage in principal amount of the Outstanding
      Debt Securities of any series, the consent of whose Holders is required
      for any 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;

            (4) modify any of the provisions of this Section, Section 5.13 or
      Section 12.7, 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 of
      each series 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
      11.2 and Section 12.7, or the deletion of this proviso, in accordance with
      the requirements of Sections 6.10 and 11.1(9); or

            (5) modify the provisions of this Indenture with respect to the
      subordination of the Outstanding Debt Securities of any series in a manner
      adverse to the Holders thereof.

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

      A supplemental indenture which changes or eliminates any covenant or other
provision of this Indenture with respect to one or more particular series of
Debt Securities and Coupons, if any, or which modifies the rights of the Holders
of Debt Securities and Coupons 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 and Coupons, if any, of any other series.

      SECTION 11.3. EXECUTION OF SUPPLEMENTAL INDENTURES.

      In executing, or accepting the additional trusts created by, any
supplemental indenture permitted by this Article XI or the modifications thereby
of the trusts created by this Indenture, the Trustee shall be entitled to
receive, and (subject to Section 6.1) shall be fully protected in relying upon,
an Opinion of Counsel stating that the execution of such supplemental indenture
is authorized or permitted by this Indenture and that the supplemental indenture
conforms to the requirements of the Trust Indenture Act as then in effect. The
Trustee may, but shall not be obligated to, enter into any such supplemental
indenture which adversely affects the Trustee's own rights, duties or immunities
under this Indenture or otherwise in a material way.

      SECTION 11.4. EFFECT OF SUPPLEMENTAL INDENTURES.

      Upon the execution of any supplemental indenture under this Article XI ,
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 and Coupons theretofore or thereafter authenticated and
delivered hereunder shall be bound thereby.

      SECTION 11.5. CONFORMITY WITH TRUST INDENTURE ACT.

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

delivered after the execution of any supplemental indenture pursuant to this
Article XI 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 and Coupons of
any series so modified as to conform, in the opinion of the Trustee and the
Board of Directors, 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 and Coupons of such series.

      SECTION 11.7. NOTICE OF SUPPLEMENTAL INDENTURE.

      Promptly after the execution by the Company and the appropriate Trustee of
any supplemental indenture pursuant to Section 11.2, the Company shall transmit,
in the manner and

<PAGE>

to the extent provided in Section 1.5, to all Holders of any series of the Debt
Securities affected thereby, a notice setting forth in general terms the
substance of such supplemental indenture.

                                  ARTICLE XII.

                                COVENANTS SECTION

      SECTION 12.1. PAYMENT OF PRINCIPAL, PREMIUM AND INTEREST.

      The Company covenants and agrees for the benefit of each series of Debt
Securities and Coupons, if any, 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, the Coupons and this
Indenture. Unless otherwise specified as contemplated by Section 3.1 with
respect to any series of Debt Securities or except as otherwise provided in
Section 3.6, any interest due on Bearer Securities on or before Maturity shall
be payable only upon presentation and surrender of the several Coupons for such
interest installments as are evidenced thereby as they severally mature. If so
provided in the terms of any series of Debt Securities established as provided
in Section 3.1, the interest, if any, due in respect of any temporary Global
Note or Permanent Global Note, together with any additional amounts payable in
respect thereof, as provided in the terms and conditions of such Debt Security,
shall be payable only upon presentation of such Debt Security to the Trustee for
notation thereon of the payment of such interest.

      SECTION 12.2. OFFICER'S CERTIFICATE AS TO DEFAULT.

      Unless otherwise specifically provided for with respect to any series of
Debt Securities under Section 3.1, the Company will deliver to the Trustee, on
or before a date not more than four months after the end of each fiscal year of
the Company (which on the date hereof is the year ending March 31) ending after
the date hereof, a certificate of the principal executive officer, principal
financial officer or principal accounting officer of the Company stating whether
or not to the best knowledge of the signer thereof the Company is in compliance
with all covenants and conditions under this Indenture, and, if the Company
shall be in default, specifying all such defaults and the nature thereof of
which such signer may have knowledge. For purposes of this Section, such
compliance shall be determined without regard to any period of grace or
requirement of notice provided under this Indenture.

      SECTION 12.3. MAINTENANCE OF OFFICE OR AGENCY.

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

                                       82
<PAGE>

of transfer, where Debt Securities of that series may be surrendered for
exchange or redemption, where notices and demands to or upon the Company in
respect of the Debt Securities of that series and this Indenture may be served
and where Bearer Securities of that series and related Coupons may be presented
or surrendered for payment in the circumstances described in the following
paragraph (and not otherwise), (B) subject to any laws or regulations applicable
thereto, in a Place of Payment for that series which is located outside the
United States, an office or agency where Debt Securities of that series and
related Coupons may be presented and surrendered for payment (including payment
of any additional amounts payable on Debt Securities of that series, if so
provided pursuant to Section 3.1); provided, however, that if the Debt
Securities of that series are listed on The Stock Exchange of the United Kingdom
and the Republic of Ireland, the Luxembourg Stock Exchange or any other stock
exchange located outside the United States and such stock exchange shall so
require, the Company will maintain a Paying Agent for the Debt Securities of
that series in London, Luxembourg or any other required city located outside the
United States, as the case may be, so long as the Debt Securities of that series
are listed on such exchange, and (C) subject to any laws or regulations
applicable thereto, in a Place of Payment for that series located outside the
United States an office or agency where any Registered Securities of that series
may be surrendered for registration of transfer, where Debt Securities of that
series may be surrendered for exchange or redemption and where notices and
demands to or upon the Company in respect of the Debt Securities of that series
and this Indenture may be served. The Company will give prompt written notice to
the Trustee of the location, and any change in the location, of such office or
agency.

      No payment of principal, premium or interest on Bearer Securities shall be
made at any office or agency of the Company in the United States or by check
mailed to any address in the United States or by transfer to an account
maintained with a bank located in the United States; provided, however, that, if
the Debt Securities of a series are denominated and payable in Dollars, payment
of principal of and any premium and interest on any Bearer Security (including
any additional amounts payable on Securities of such series, if so provided
pursuant to Section 3.1) shall be made at the office of the Company's Paying
Agent in the Borough of Manhattan, The City and State of New York, if (but only
if) payment in Dollars of the full amount of such principal, premium, interest
or additional amounts, as the case may be, at all offices or agencies 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.

      The Company may also from time to time designate different or additional
offices or agencies to be maintained for such purposes (in or outside of such
Place of Payment), and may from time to time rescind any such designations;
provided, however, that no such designation or rescission shall in any manner
relieve the Company of its obligations described in the preceding paragraph. The
Company will give prompt written notice to the Trustee of any such additional
designation or rescission of designation and any change in the location of any
such different or additional office or agency.

      SECTION 12.4. 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 and Coupons, if any, 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

                                       83
<PAGE>

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 and Coupons, it will, by 10:00 a.m. (New York City
time) or on each due date of the principal (and premium, if any) or interest on
any Debt Securities of such series, deposit with any such 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
thereto, and (unless any such Paying Agent is the Trustee) the Company will
promptly notify the Trustee of its action or failure so to act.

      Notwithstanding any term herein to the contrary, in no instance shall the
Trustee be under any duty or obligation (i) to maintain any office or to act in
any capacity as an agent for any purpose under this Indenture (or any supplement
hereto) outside the United States, or (ii) to act as a Paying Agent in respect
of any currency other than Dollars.

      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) in the making of
      any payment of principal (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 obtaining the satisfaction
and discharge of this Indenture or for any other purpose, pay, or by Company
Order direct any Paying Agent to pay, to the Trustee all sums held in trust by
the Company or such Paying Agent, such sums to be held by the Trustee upon the
same trusts as those upon which such sums were held by the Company or such
Paying Agent; and, upon such payment by any Paying Agent to the Trustee, such
Paying Agent shall be released from all further liability with respect to such
money.

      Any money deposited with the Trustee or any Paying Agent, or then held by
the Company, in trust for the payment of the principal of (and premium, if any)
or interest on any Debt Security of any series and remaining unclaimed for two
years after such principal (and

                                       84
<PAGE>

premium, if any) or interest has become due and payable shall be paid to the
Company upon Company Request, or (if then held by the Company) shall be
discharged from such trust; and the Holder of such Debt Security or Coupon shall
thereafter, as an unsecured general creditor, look only to the Company for
payment thereof, and all liability of the Trustee or such Paying Agent with
respect to such trust money, and all liability of the Company as trustee
thereof, shall thereupon cease; provided, however, that the Trustee or such
Paying Agent, before being required to make any such repayment, may at the
expense of the Company cause to be transmitted in the manner and to the extent
provided by Section 1.5, 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 notification, any unclaimed balance of such money then remaining
will be repaid to the Company.

      SECTION 12.5. CORPORATE EXISTENCE.

      Subject to Article X, 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
Company shall determine that the preservation thereof is no longer desirable in
the conduct of the business of the Company.

      SECTION 12.6. PURCHASE OF DEBT SECURITIES BY COMPANY.

      If the Debt Securities of a series are listed on The Stock Exchange of the
United Kingdom and the Republic of Ireland and such stock exchange shall so
require, the Company will not purchase any Debt Securities of that series by
private treaty at a price (exclusive of expenses and accrued interest) which
exceeds 120% of the mean of the nominal quotations of the Debt Securities of
that series as shown in The Stock Exchange Daily Official List for the last
trading day preceding the date of purchase.

      SECTION 12.7. WAIVER OF CERTAIN COVENANTS.

      The Company may omit in any particular instance to comply with any term,
provision or condition set forth in Sections 12.5 and 12.6 (and, if so specified
pursuant to Section 3.1, any other covenant not set forth herein and specified
pursuant to Section 3.1 to be applicable to the Securities of any series, except
as otherwise provided pursuant to Section 3.1) 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 Outstanding Debt Securities of
such series shall, by Act of such Holders, either waive such compliance in such
instance or generally waive compliance with such term, provision or condition,
but no such waiver shall extend to or affect such term, provision or condition
except to the extent expressly so waived, and, until such waiver shall become
effective, the obligations of the Company and the duties of the Trustee in
respect of any such term, provision or condition shall remain in full force and
effect.

                                 ARTICLE XIII.

                         REDEMPTION OF DEBT SECURITIES

      SECTION 13.1. APPLICABILITY OF ARTICLE.

      Debt Securities of any series which are redeemable before their Maturity
shall be redeemable in accordance with their terms and (except as otherwise
specified pursuant to Section 3.1 for Debt Securities of any series) in
accordance with this Article XIII.

      SECTION 13.2. ELECTION TO REDEEM; NOTICE TO TRUSTEE.

      The election of the Company to redeem (or, in the case of Discount
Securities, to permit the Holders to elect to surrender for redemption) 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 pursuant to Section 13.3, the Company shall, at least 30 days before the
Redemption Date fixed by the Company (unless a shorter notice shall be
satisfactory to the Trustee), notify the Trustee of such Redemption Date and of
the principal amount of Debt Securities of such 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 restrictions.

      SECTION 13.3. SELECTION BY TRUSTEE OF DEBT SECURITIES TO BE REDEEMED.

      Except in the case of a redemption in whole of the Bearer Securities or
the Registered Securities of such series, if less than all the Debt Securities
of any series are to be redeemed at the election of the Company, 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 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) of the principal amount of Debt
Securities of such series in a denomination larger than the minimum authorized
denomination for Debt Securities of such series pursuant to Section 3.2 in the
Currency in which the Debt Securities of such series are denominated. The
portions of the principal amount of Debt Securities so selected for partial
redemption shall be equal to the minimum authorized denominations for Debt
Securities of such series pursuant to Section 3.2 in the Currency in which the
Debt Securities of such series are denominated or any integral multiple thereof,
except as otherwise set forth in the applicable form of Debt Securities. In any
case when more than one Registered Security of such series is registered in the
same name, the Trustee in its discretion may treat the aggregate principal
amount so registered as if it were represented by one Registered Security of
such series.

      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.

                                       86
<PAGE>

      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 13.4. NOTICE OF REDEMPTION.

      Notice of redemption 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, not less
than 30 days and not more than 60 days prior to the Redemption Date to the
Holders of Debt Securities of any series to be redeemed in whole or in part
pursuant to this Article XIII, in the manner provided in Section 1.5. Any notice
so given shall be conclusively presumed to have been duly given, whether or not
the Holder receives such notice. Failure to give such notice, or any defect in
such notice to the Holder of any Debt Security of a series designated for
redemption, in whole or in part, shall not affect the sufficiency of any notice
of redemption with respect to the Holder of any other Debt Security of such
series.

      All notices of redemption shall state:

            (1) the Redemption Date;

            (2) the Redemption Price;

            (3) that Debt Securities of such series are being redeemed by the
      Company pursuant to provisions contained in this Indenture or the terms of
      the Debt Securities of such series or a supplemental indenture
      establishing such series, if such be the case, together with a brief
      statement of the facts permitting such redemption;

            (4) 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;

            (5) 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, if any, shall cease to accrue on and after said date;

            (6) that, unless otherwise specified in such notice, Coupon
      Securities of any series, if any, surrendered for redemption must be
      accompanied by all Coupons maturing subsequent to the date fixed for
      redemption, failing which the amount of any such missing Coupon or Coupons
      will be deducted from the Redemption Price;

            (7) the Place or Places of Payment where such Debt Securities are to
      be surrendered for payment of the Redemption Price;

            (8) if Bearer Securities of any series are to be redeemed and any
      Registered Securities of such series are not to be redeemed, and if such
      Bearer

                                       87
<PAGE>

      Securities may be exchanged for Registered Securities not subject to
      redemption on this Redemption Date pursuant to Section 3.5(b) or
      otherwise, the last date on which such exchanges may be made; and

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

      SECTION 13.5. DEPOSIT OF REDEMPTION PRICE.

      On or prior to 10:00 a.m. (New York City time) on the Redemption Date for
any Debt Securities, 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 12.4) an amount of money in the Currency or
Currencies in which such Debt Securities are denominated (except as provided
pursuant to Section 3.1) sufficient to pay the Redemption Price of such Debt
Securities or any portions thereof which are to be redeemed on that date.

      SECTION 13.6. DEBT SECURITIES PAYABLE ON REDEMPTION DATE.

      Notice of redemption having been given as aforesaid, any Debt Securities
so to be redeemed shall become due and payable on the Redemption Date, at the
Redemption Price in the Currency in which the Debt Securities of such series are
payable (except as otherwise specified pursuant to Section 3.1 or 3.10), and on
and after such date (unless the Company shall default in the payment of the
Redemption Price) such Debt Securities shall cease to bear interest. 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;
provided, however, that installments of interest on Bearer Securities whose
Stated Maturity is on or prior to the Redemption Date shall be payable only at
an office or agency located outside the United States (except as otherwise
provided in Section 12.3) and, unless otherwise specified as contemplated by
Section 3.1, only upon presentation and surrender of Coupons for such interest;
and provided, further, that, unless otherwise specified as contemplated by
Section 3.1, installments of interest on Registered Securities which have a
Stated Maturity on or prior to the Redemption Date for such Debt Securities
shall be payable according to the terms of such Debt Securities and the
provisions of Section 3.7.

      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.

      If any Coupon Security surrendered for redemption shall not be accompanied
by all Coupons appertaining thereto maturing on or after the Redemption Date,
the Redemption Price for such Coupon Security may be reduced by an amount equal
to the face amount of all such missing Coupons. If thereafter the Holder of such
Coupon shall surrender to any Paying Agent outside the United States 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. 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.

                                       88
<PAGE>

      SECTION 13.7. DEBT SECURITIES REDEEMED IN PART.

      Any Debt Security which is to be redeemed only in part shall be
surrendered at the Corporate Trust Office or such other office or agency of the
Company as is specified pursuant to Section 3.1 (in the case of Registered
Securities) and at an office of the Trustee, or at such other office or agency
of the Company outside the United States as is specified pursuant to Section 3.1
(in the case of Bearer Securities) with, if the Company, the Security Registrar
or the Trustee so requires, due endorsement by, or a written instrument of
transfer in form satisfactory to the Company, the Security Registrar and the
Trustee duly executed by, the Holder thereof or his attorney duly authorized in
writing, and the Company shall execute, and the Trustee shall authenticate and
deliver to the Holder of such Debt Security without service charge, a new Debt
Security or Debt Securities of the same series, of like tenor and form, of any
authorized denomination as requested by such Holder in aggregate principal
amount equal to and in exchange for the unredeemed portion of the principal of
the Debt Security so surrendered, and, in the case of a Coupon Security, with
appropriate Coupons attached. In the case of a Debt Security providing
appropriate space for such notation, at the option of the Holder thereof, the
Trustee, in lieu of delivering a new Debt Security or Debt Securities as
aforesaid, may make a notation on such Debt Security of the payment of the
redeemed portion thereof.

      SECTION 13.8. CONVERSION ARRANGEMENT IN CALL FOR REDEMPTION.

In connection with any redemption of Debt Securities of any series, the Company
may arrange for the purchase and conversion of any such Debt Securities by an
agreement with one or more investment bankers or other purchasers to purchase
such Debt Securities by paying to the Trustee or the Paying Agent in trust for
the Holders of such Debt Securities, on or before 10:00 a.m. New York time on
the Redemption Date, an amount not less than the Redemption Price, together with
interest, if any, accrued to the redemption date of such Debt Securities, in
immediately available funds. Notwithstanding anything to the contrary contained
in this Article XIII, the obligation of the Company to pay the Redemption Price
of such Debt Securities, including all accrued interest, if any, shall be deemed
to be satisfied and discharged to the extent such amount is so paid by such
purchasers. If such an agreement is entered into, any Debt Securities not duly
surrendered for conversion by the Holders thereof, at the option of the Company,
may be deemed, to the fullest extent permitted by law, acquired by such
purchasers from such Holders and surrendered by such purchasers for conversion,
all as of immediately prior to the close of business on the last Business Day on
which such Debt Securities called for redemption may be converted in accordance
with this Indenture and the terms of such Debt Securities, subject to payment to
the Trustee or Paying Agent of the above-described amount. The Trustee or the
Paying Agent shall hold and pay to the Holders whose Debt Securities are
selected for redemption any such amount paid to it in the same manner as it
would pay funds deposited with it by the Company for the redemption of Debt
Securities of such series. Without the Trustee's and the Paying Agent's prior
written consent, no arrangement between the Company and such purchasers for the
purchase and conversion of any Securities shall increase or otherwise affect any
of the powers, duties, responsibilities or obligations of the Trustee and the
Paying Agent as set forth in this Indenture.

                                  ARTICLE XIV.

                                  SINKING FUNDS

      SECTION 14.1. APPLICABILITY OF ARTICLE.

      The provisions of this Article XIV shall be applicable to any sinking fund
for the retirement of Debt Securities of a series except as otherwise specified
pursuant to Section 3.1 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 as an "optional
sinking fund payment." If provided for by the terms of Debt Securities of any
series, the amount of any cash sinking fund payment may be subject to reduction
as provided in Section 14.2. 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 14.2. SATISFACTION OF MANDATORY SINKING FUND PAYMENTS WITH DEBT
SECURITIES.

      In lieu of making all or any part of a mandatory sinking fund payment with
respect to any Debt Securities of a series in cash, the Company may at its
option, at any time no more than sixteen months and no less than 45 days prior
to the date on which such sinking fund payment is due, deliver to the Trustee
Debt Securities of such series (together with the unmatured Coupons, if any,
appertaining thereto) theretofore purchased or otherwise acquired by the
Company, except Debt Securities of such series which have been redeemed through
the application of mandatory sinking fund payments pursuant to the terms of the
Debt Securities of such series, accompanied by a Company Order instructing the
Trustee to credit such obligations and stating that the Debt Securities of such
series were originally issued by the Company by way of bona fide sale or other
negotiation for value, provided that such Debt Securities shall not have 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 mandatory sinking fund payment shall be reduced accordingly.

      SECTION 14.3. REDEMPTION OF DEBT SECURITIES FOR SINKING FUND.

      Not less than 60 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 in the Currency or Currencies in which the Debt
Securities of such series are denominated (except as provided pursuant to
Section 3.1) and the portion thereof, if any, which is to be satisfied by
delivering and crediting Debt Securities of such series pursuant to Section 14.2
and whether the Company intends to exercise its rights to make a permitted

                                       90
<PAGE>

optional sinking fund payment with respect to such series. Such certificate
shall be irrevocable and upon its delivery the Company shall be obligated to
make the cash payment or payments therein referred to, if any, on or before the
next succeeding sinking fund payment date. In the case of the failure of the
Company to deliver such certificate, the sinking fund payment due on the next
succeeding sinking fund payment date for such series shall be paid entirely in
cash and shall be sufficient to redeem the principal amount of the Debt
Securities of such series subject to a mandatory sinking fund payment without
the right to deliver or credit Debt Securities as provided in Section 14.2 and
without the right to make any optional sinking fund payment with respect to such
series at such time.

      Any sinking fund payment or payments (mandatory or optional) made in cash
plus any unused balance of any preceding sinking fund payments made with respect
to the Debt Securities of any particular series shall be applied by the Trustee
(to the extent it is acting as a Paying Agent with respect to Dollars) or other
Paying Agent appointed by the Company (or by the Company if the Company is
acting as its own Paying Agent) on the sinking fund payment date on which such
payment is made (or, if such payment is made before a sinking fund payment date,
on the sinking fund payment date immediately following the date of such payment)
to the redemption of Debt Securities of such series at the Redemption Price
specified in such Debt Securities with respect to the sinking fund. Any sinking
fund moneys not so applied or allocated by the Trustee (to the extent it is
acting as a Paying Agent with respect to Dollars) or other Paying Agent
appointed by the Company (or by the Company if the Company is acting as its own
Paying Agent) to the redemption of Debt Securities shall be added to the next
sinking fund payment received by the Trustee (to the extent it is acting as a
Paying Agent with respect to Dollars) or other Paying Agent appointed by the
Company (or if the Company is acting as its own Paying Agent, segregated and
held in trust as provided in Section 12.4) for such series and, together with
such payment (or such amount so segregated) shall be applied in accordance with
the provisions of this Section. Any and all sinking fund moneys with respect to
the Debt Securities of any particular series held by the Trustee (to the extent
it is acting as a Paying Agent with respect to Dollars) or other Paying Agent
appointed by the Company (or if the Company is acting as its own Paying Agent,
segregated and held in trust as provided in Section 12.4) on the last sinking
fund payment date with respect to Debt Securities of such series and not held
for the payment or redemption of particular Debt Securities of such series shall
be applied by the Trustee (to the extent it is acting as a Paying Agent with
respect to Dollars) or other Paying Agent appointed by the Company (or by the
Company if the Company is acting as its own Paying Agent), together with other
moneys, if necessary, to be deposited (or segregated) sufficient for the
purpose, to the payment of the principal of the Debt Securities of such series
at Maturity.

      The Trustee shall select or cause to be selected the Debt Securities to be
redeemed upon such sinking fund payment date in the manner specified in Section
13.3 and the Company shall cause notice of the redemption thereof to be given in
the manner provided in Section 13.4. Such notice having been duly given, the
redemption of such Debt Securities shall be made upon the terms and in the
manner stated in Section 13.6.

      On or before 10:00 a.m. (New York City time) on each sinking fund payment
date, the Company shall pay to the Trustee (to the extent it is acting as a
Paying Agent with respect to Dollars) or other Paying Agent appointed by the
Company (or, if the Company is acting as its

                                       91
<PAGE>

own Paying Agent, the Company shall segregate and hold in trust as provided in
Section 12.4) in cash a sum, in the Currency or Currencies in which Debt
Securities of such series are denominated (except as provided pursuant to
Sections 3.1 or 3.10), equal to the principal and any interest accrued to the
Redemption Date for Debt Securities or portions thereof to be redeemed on such
sinking fund payment date pursuant to this Section.

      Neither the Trustee, any Paying Agent nor the Company shall redeem any
Debt Securities of a series with sinking fund moneys or mail any notice of
redemption of Debt Securities of such series by operation of the sinking fund
for such series during the continuance of a default in payment of interest, if
any, on any Debt Securities of such series or of any Event of Default (other
than an Event of Default occurring as a consequence of this paragraph) with
respect to the Debt Securities of such series, except that if the notice of
redemption shall have been provided in accordance with the provisions hereof,
the Trustee or applicable Paying Agent (or the Company, if the Company is then
acting as its own Paying Agent) shall redeem such Debt Securities if cash
sufficient for that purpose shall be deposited with the Trustee or such other
Paying Agent as provided above (or segregated by the Company) for that purpose
in accordance with the terms of this Article XIV. Except as aforesaid, any
moneys in the sinking fund for such series at the time when any such default or
Event of Default shall occur and any moneys thereafter paid into such sinking
fund shall, during the continuance of such default or Event of Default, be held
as security for the payment of the Debt Securities and Coupons, if any, of such
series; provided, however, that in case such default or Event of Default shall
have been cured or waived as provided herein, such moneys shall thereafter be
applied on or prior to the next sinking fund payment date for the Debt
Securities of such series on which such moneys may be applied pursuant to the
provisions of this Section.

                                  ARTICLE XV.

                                   DEFEASANCE

      SECTION 15.1. APPLICABILITY OF ARTICLE.

      If, pursuant to Section 3.1, provision is made for the defeasance of Debt
Securities of a series, and if the Debt Securities of such series are Registered
Securities and denominated and payable only in Dollars (except as provided
pursuant to Section 3.1 and subject to the proviso in the last sentence of this
paragraph) then the provisions of this Article XV shall be applicable except as
otherwise specified pursuant to Section 3.1 for Debt Securities of such series.
Defeasance provisions, if any, for Debt Securities denominated and/or payable in
a Foreign Currency or Currencies or for Bearer Securities may be specified
pursuant to Section 3.1; provided, however, that nothing herein or therein shall
obligate the Trustee (without its consent, at its sole option) to hold or
maintain any account, or act as Paying Agent with respect to, any Foreign
Currency or Currencies.

      SECTION 15.2. DEFEASANCE UPON DEPOSIT OF MONEYS OR U.S. GOVERNMENT
OBLIGATIONS.

      At the Company's option, either (a) the Company shall be deemed to have
been Discharged (as defined below) from its obligations with respect to Debt
Securities of any series ("legal defeasance option") or (b) the Company shall
cease to be under any obligation to comply

                                       92
<PAGE>

with any term, provision or condition set forth in Article X with respect to
Debt Securities of any series (and, if so specified pursuant to Section 3.1, any
other obligation of the Company or restrictive covenant added for the benefit of
such series pursuant to Section 3.1) ("covenant defeasance option") at any time
after the applicable conditions set forth below have been satisfied:

            (1) the Company shall have deposited or caused to be deposited
      irrevocably with the Trustee as trust funds in trust, specifically pledged
      as security for, and dedicated solely to, the benefit of the Holders of
      the Debt Securities of such series (i) money in an amount, or (ii) U.S.
      Government Obligations (as defined below) which through the payment of
      interest and principal in respect thereof in accordance with their terms
      will provide, not later than one day before the due date of any payment,
      money in an amount, or (iii) a combination of (i) and (ii), sufficient, in
      the opinion (with respect to (i) and (ii)) of a nationally recognized firm
      of independent public accountants expressed in a written certification
      thereof delivered to the Trustee, to pay and discharge each installment of
      principal (including any mandatory sinking fund payments) of and premium,
      if any, and interest on, the Outstanding Debt Securities of such series on
      the dates such installments of interest or principal and premium are due;

            (2) such deposit shall not cause the Trustee with respect to the
      Debt Securities of that series to have a conflicting interest as defined
      in Section 6.8 and for purposes of the Trust Indenture Act with respect to
      the Debt Securities of any series;

            (3) such deposit will not result in a breach or violation 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) if the Debt Securities of such series are then listed on any
      national securities exchange, the Company shall have delivered to the
      Trustee an Opinion of Counsel or a letter or other document from such
      exchange to the effect that the Company's exercise of its option under
      this Section would not cause such Debt Securities to be delisted;

            (5) no Event of Default or event (including such deposit) which,
      with notice or lapse of time or both, would become an Event of Default
      with respect to the Debt Securities of such series shall have occurred and
      be continuing on the date of such deposit and, with respect to the legal
      defeasance option only, no Event of Default under Section 5.1(5) or
      Section 5.1(6) or event which with the giving of notice or lapse of time,
      or both, would become an Event of Default under Section 5.1(5) or Section
      5.1(6) shall have occurred and be continuing on the 91st day after such
      date;

            (6) the Company shall have delivered to the Trustee an Opinion of
      Counsel or a ruling from the Internal Revenue Service to the effect that
      the Holders of the Debt Securities of such series will not recognize
      income, gain or

                                       93
<PAGE>

      loss for Federal income tax purposes as a result of such deposit,
      defeasance or Discharge; and

            (7) no event or condition shall exist that, pursuant to the
      provisions of Article XVII, would prevent the Company from making payments
      of the principal of (and premium, if any) or interest on the Debt
      Securities of such series and Coupons appertaining thereto on the date of
      such deposit.

Notwithstanding the foregoing, if the Company exercises its covenant defeasance
option and an Event of Default under Section 5.1(5) or Section 5.1(6) or an
event which with the giving of notice or lapse of time, or both, would become an
Event of Default under Section 5.1(5) or Section 5.1(6) shall have occurred and
be continuing on the 91st day after the date of such deposit, the obligations of
the Company referred to under the definition of covenant defeasance option with
respect to such Debt Securities shall be reinstated.

Notwithstanding the Company's exercise of the covenant defeasance option, the
Company may subsequently exercise the legal defeasance option.

      "Discharged" means that the Company shall be deemed to have paid and
discharged the entire indebtedness represented by, and obligations under, the
Debt Securities of such series and to have satisfied all the obligations under
this Indenture relating to the Debt Securities of such series (and the Trustee
for such series of Debt Securities, at the expense of the Company, shall execute
proper instruments acknowledging the same), except (A) the rights of Holders of
Debt Securities of such series to receive, from the trust fund described in
clause (1) above, payment of the principal of (and premium, if any) and interest
on such Debt Securities when such payments are due, (B) the Company's
obligations with respect to the Debt Securities of such series under Sections
3.4, 3.5, 3.6, 12.3 and 15.3 and (C) the rights, powers, trusts, duties and
immunities of the Trustee hereunder.

      "U.S. Government Obligations" means securities that are (i) direct
obligations of the United States for the payment of which its full faith and
credit is pledged, or (ii) obligations of a Person controlled or supervised by
and acting as an agency or instrumentality of the United States the payment of
which is unconditionally guaranteed as a full faith and credit obligation by the
United States, which, in either case under clauses (i) or (ii), are not callable
or redeemable at the option of the issuer thereof, and shall also include a
depository receipt issued by a bank or trust company as custodian with respect
to any such U.S. Government Obligation or a specific payment of interest on or
principal of any such U.S. Government Obligation held by such custodian for the
account of the holder of a depository receipt; provided that (except as required
by law) such custodian is not authorized to make any deduction from the amount
payable to the holder of such depository receipt from any amount received by the
custodian in respect of the U.S. Government Obligation or the specific payment
of interest on or principal of the U.S. Government Obligation evidenced by such
depository receipt.

<PAGE>

      SECTION 15.3. DEPOSITED MONEYS AND U.S. GOVERNMENT OBLIGATIONS TO BE HELD
IN TRUST.

      All moneys and U.S. Government Obligations deposited with the Trustee
pursuant to Section 15.2 in respect of Debt Securities of a series shall be held
in trust and applied by it, in accordance with the provisions of such Debt
Securities and this Indenture, to the payment, either directly or through any
Paying Agent (including the Company acting as its own Paying Agent) as the
Trustee may determine, to the Holders of such Debt Securities, of all sums due
and to become due thereon for principal (and premium, if any) and interest, if
any, but such money need not be segregated from other funds except to the extent
required by law.

      SECTION 15.4. REPAYMENT TO COMPANY.

      The Trustee and any Paying Agent shall promptly pay or return to the
Company upon Company Request any moneys or U.S. Government Obligations held by
them at any time that are not required for the payment of the principal of (and
premium, if any) and interest on the Debt Securities of any series for which
money or U.S. Government Obligations have been deposited pursuant to Section
15.2.

      The provisions of the last paragraph of Section 12.4 shall apply to any
money held by the Trustee or any Paying Agent under this Article XV that remains
unclaimed for two years after the Maturity of any series of Debt Securities for
which money or U.S. Government Obligations have been deposited pursuant to
Section 15.2.

                                  ARTICLE XVI.

                                   CONVERSION

      SECTION 16.1. APPLICABILITY; CONVERSION PRIVILEGE.

      Except as otherwise specified pursuant to Section 3.1 for Debt Securities
of any series, the provisions of this Article XVI shall be applicable to any
Debt Securities that are convertible into Common Stock. If so provided pursuant
to Section 3.1 with respect to the Debt Securities of any series, the Holder of
a Debt Security of such series shall have the right, at such Holder's option, to
convert, in accordance with the terms of such series of Debt Securities and this
Article XVI, all or any part (in a denomination of, unless otherwise specified
pursuant to Section 3.1 with respect to Securities of such series, $1,000 in
principal amount or any integral multiple thereof) of such Debt Security into
shares of Common Stock or, as to any Debt Securities called for redemption, at
any time prior to the time and date fixed for such redemption (unless the
Company shall default in the payment of the Redemption Price, in which case such
right shall not terminate at such time and date).

      SECTION 16.2. CONVERSION PROCEDURE; CONVERSION PRICE; FRACTIONAL SHARES.

      (a) Each Debt Security to which this Article XVI is applicable shall be
convertible at the office of the Conversion Agent, and at such other place or
places, if any, specified pursuant to Section 3.1 with respect to the Debt
Securities of such series, into fully paid and nonassessable shares (calculated
to the nearest 1/100th of a share) of Common Stock. The Debt Securities will

                                       95
<PAGE>

be converted into shares of Common Stock at the Conversion Price therefor. No
payment or adjustment shall be made in respect of dividends on the Common Stock
or accrued interest on a converted Debt Security except as described in Section
16.9. The Company may, but shall not be required, in connection with any
conversion of Debt Securities, to issue a fraction of a share of Common Stock
and, if the Company shall determine not to issue any such fraction, the Company
shall, subject to Section 16.3(4), make a cash payment (calculated to the
nearest cent) equal to such fraction multiplied by the Closing Price of the
Common Stock on the last Trading Day prior to the date of conversion.

      (b) Before any Holder of a Debt Security shall be entitled to convert the
same into Common Stock, such Holder shall surrender such Debt Security duly
endorsed to the Company or in blank, or, in the case of Bearer Securities,
together with all unmatured Coupons and any matured Coupons in default attached
thereto, at the office of the Conversion Agent or at such other place or places,
if any, specified pursuant to Section 3.1 (in the case of Registered Securities)
and at an office of the Conversion Agent or at such other place or places, if
any, outside of the United States as is specified pursuant to Section 3.1 (in
the case of Bearer Securities), and shall give written notice to the Company at
said office or place that he elects to convert the same and shall state in
writing therein the principal amount of Debt Securities to be converted and the
name or names (with addresses) in which he wishes the certificate or
certificates for Common Stock to be issued; provided, however, that no Debt
Security or portion thereof shall be accepted for conversion unless the
principal amount of such Debt Security or such portion, when added to the
principal amount of all other Debt Securities or portions thereof then being
surrendered by the Holder thereof for conversion, exceeds the then effective
Conversion Price with respect thereto. 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 conversion may be effected if the Bearer Securities to
be surrendered for conversion are accompanied by payment in funds acceptable to
the Company in an amount equal to the face amount of such missing Coupon or
Coupons, or the surrender of such missing Coupon or Coupons may be waived by the
Company and the Trustee if there is furnished to them such security or indemnity
as they may require to save each of them and any Paying Agent harmless. If
thereafter the Holder of such Bearer Security shall surrender to any Paying
Agent any such missing Coupon in respect of which such a payment shall have been
made, such Holder shall be entitled to receive the amount of such payment;
provided, however that except as otherwise provided in Section 12.3, 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. If more
than one Debt Security shall be surrendered for conversion at one time by the
same Holder, the number of full shares of Common Stock which shall be
deliverable upon conversion shall be computed on the basis of the aggregate
principal amount of the Debt Securities (or specified portions thereof to the
extent permitted thereby) so surrendered. Subject to the next succeeding
sentence, the Company will, as soon as practicable thereafter, issue and deliver
at said office or place to such Holder of a Debt Security, or to his nominee or
nominees, certificates for the number of full shares of Common Stock to which he
shall be entitled as aforesaid, together, subject to the last sentence of
paragraph (a) above, with cash in lieu of any fraction of a share to which he
would otherwise be entitled. The Company shall not be required to deliver
certificates for shares of Common Stock while the stock transfer books for such
stock or the Security Register are duly closed for any purpose, but certificates
for shares of Common Stock shall be issued and delivered as soon as practicable
after the opening of such books or

                                       96
<PAGE>

Security Register. A Debt Security shall be deemed to have been converted as of
the close of business on the date of the surrender of such Debt Security for
conversion as provided above, and the Person or Persons entitled to receive the
Common Stock issuable upon such conversion shall be treated for all purposes as
the record Holder or Holders of such Common Stock as of the close of business on
such date. In case any Debt Security shall be surrendered for partial
conversion, the Company shall execute and the Trustee shall authenticate and
deliver to or upon the written order of the Holder of the Debt Securities so
surrendered, without charge to such Holder (subject to the provisions of Section
16.8), a new Debt Security or Securities in authorized denominations in an
aggregate principal amount equal to the unconverted portion of the surrendered
Debt Security.

      SECTION 16.3. ADJUSTMENT OF CONVERSION PRICE FOR COMMON STOCK.

      The Conversion Price with respect to any Debt Security which is
convertible into Common Stock shall be adjusted from time to time as follows:

            (1) In case the Company shall, at any time or from time to time
      while any of such Debt Securities are outstanding, (i) pay a dividend in
      shares of its Common Stock to holders of Common Stock, (ii) combine its
      outstanding shares of Common Stock into a smaller number of shares of
      Common Stock, (iii) subdivide its outstanding shares of Common Stock into
      a greater number of shares of Common Stock or (iv) make a distribution in
      shares of Common Stock to holders of Common Stock, then the Conversion
      Price in effect immediately before such action shall be adjusted so that
      the Holders of such Debt Securities, upon conversion thereof into Common
      Stock immediately following such event, shall be entitled to receive the
      kind and amount of shares of capital stock of the Company which they would
      have owned or been entitled to receive upon or by reason of such event if
      such Debt Securities had been converted immediately before the record date
      (or, if no record date, the effective date) for such event. An adjustment
      made pursuant to this Section 16.3(1) shall become effective retroactively
      immediately after the record date in the case of a dividend or
      distribution and shall become effective retroactively immediately after
      the effective date in the case of a subdivision or combination. For the
      purposes of this Section 16.3(1), each Holder of Debt Securities shall be
      deemed to have failed to exercise any right to elect the kind or amount of
      securities receivable upon the payment of any such dividend, subdivision,
      combination or distribution (provided that if the kind or amount of
      securities receivable upon such dividend, subdivision, combination or
      distribution is not the same for each nonelecting share, then the kind and
      amount of securities or other property receivable upon such dividend,
      subdivision, combination or distribution for each nonelecting share shall
      be deemed to be the kind and amount so receivable per share by a plurality
      of the nonelecting shares).

            (2) In case the Company shall, at any time or from time to time
      while any of such Debt Securities are outstanding, issue rights or
      warrants to all holders of shares of its Common Stock entitling them (for
      a period expiring within 45 days after the record date for such issuance)
      to subscribe for or purchase shares of

                                       97
<PAGE>

      Common Stock (or securities convertible into shares of Common Stock) at a
      price per share less than the Current Market Price of the Common Stock at
      such record date (treating the price per share of the securities
      convertible into Common Stock as equal to (x) the sum of (i) the price for
      a unit of the security convertible into Common Stock and (ii) any
      additional consideration initially payable upon the conversion of such
      security into Common Stock divided by (y) the number of shares of Common
      Stock initially underlying such convertible security), the Conversion
      Price with respect to such Debt Securities shall be adjusted so that it
      shall equal the price determined by dividing the Conversion Price in
      effect immediately prior to the date of issuance of such rights or
      warrants by a fraction, the numerator of which shall be the number of
      shares of Common Stock outstanding on the date of issuance of such rights
      or warrants plus the number of additional shares of Common Stock offered
      for subscription or purchase (or into which the convertible securities so
      offered are initially convertible), and the denominator of which shall be
      the number of shares of Common Stock outstanding on the date of issuance
      of securities which the aggregate offering price of the total number of
      shares of securities so offered for subscription or purchase (or the
      aggregate purchase price of the convertible securities so offered plus the
      aggregate amount of any additional consideration initially payable upon
      conversion of such securities into Common Stock) would purchase at such
      Current Market Price of the Common Stock. Such adjustment shall become
      effective retroactively immediately after the record date for the
      determination of shareholders entitled to receive such rights or warrants.

            (3) In the case the Company shall, at any time or from time to time
      while any of such Debt Securities are outstanding, distribute to all
      holders of shares of its Common Stock (including any such distribution
      made in connection with a consolidation or merger in which the Company is
      the continuing corporation and the Common Stock is not changed or
      exchanged) cash, evidences of its indebtedness, securities or assets
      (excluding (i) regular periodic cash dividends in amounts, if any,
      determined from time to time by the Board of Directors, (ii) dividends
      payable in shares of Common Stock for which adjustment is made under
      Section 16.3(1) or (iii) rights or warrants to subscribe for or purchase
      securities of the Company (excluding those referred to in Section
      16.3(2))), then in each such case the Conversion Price with respect to
      such Debt Securities determined by dividing the Conversion Price in effect
      immediately prior to the date of such distribution by a fraction, the
      numerator of which shall be the Current Market Price of the Common Stock
      on the record date referred to below, and the denominator of which shall
      be such Current Market Price of the Common Stock less the then fair market
      value (as determined by the Board of Directors of the Company, whose
      determination shall be conclusive) of the portion of the cash or assets or
      evidences of indebtedness or securities so distributed or of such
      subscription rights or warrants applicable to one share of Common Stock
      (provided that such denominator shall never be less than 1.0); provided
      however, that no adjustment shall be made with respect to any distribution
      of rights to purchase securities of the Company if a Holder of Debt
      Securities would otherwise be entitled to receive such rights upon
      conversion at

                                       98
<PAGE>

      any time of such Debt Securities into Common Stock unless such rights are
      subsequently redeemed by the Company, in which case such redemption shall
      be treated for purposes of this section as a dividend on the Common Stock.
      Such adjustment shall become effective retroactively immediately after the
      record date for the determination of shareholders entitled to receive such
      distribution; and in the event that such distribution is not so made, the
      Conversion Price shall again be adjusted to the Conversion Price which
      would then be in effect if such record date had not been fixed.

            (4) The Company shall be entitled to make such additional
      adjustments in the Conversion Price, in addition to those required by
      subsections 16.3(1), 16.3(2), and 16.3(3), as shall be necessary in order
      that any dividend or distribution of Common Stock, any subdivision,
      reclassification or combination of shares of Common Stock or any issuance
      of rights or warrants referred to above shall not be taxable to the
      holders of Common Stock for United States Federal income tax purposes.

            (5) In any case in which this Section 16.3 shall require that any
      adjustment be made effective as of or retroactively immediately following
      a record date, the Company may elect to defer (but only for five (5)
      Trading Days following the filing of the statement referred to in Section
      16.5) issuing to the Holder of any Debt Securities converted after such
      record date the shares of Common Stock and other capital stock of the
      Company issuable upon such conversion over and above the shares of Common
      Stock and other capital stock of the Company issuable upon such conversion
      on the basis of the Conversion Price prior to adjustment; provided,
      however, that the Company shall deliver to such Holder a due bill or other
      appropriate instrument evidencing such Holder's right to receive such
      additional shares upon the occurrence of the event requiring such
      adjustment.

            (6) All calculations under this Section 16.3 shall be made to the
      nearest cent or one-hundredth of a share of security, with one-half cent
      and 0.005 of a share, respectively, being rounded upward. Notwithstanding
      any other provision of this Section 16.3, the Company shall not be
      required to make any adjustment of the Conversion Price unless such
      adjustment would require an increase or decrease of at least 1% of such
      price. Any lesser adjustment shall be carried forward and shall be made at
      the time of and together with the next subsequent adjustment which,
      together with any adjustment or adjustments so carried forward, shall
      amount to an increase or decrease of at least 1% in such price. Any
      adjustments under this Section 16.3 shall be made successively whenever an
      event requiring such an adjustment occurs.

            (7) In the event that at any time, as a result of an adjustment made
      pursuant to this Section 16.3, the Holder of any Debt Security thereafter
      surrendered for conversion shall become entitled to receive any shares of
      stock of the Company other than shares of Common Stock into which the Debt
      Securities originally were convertible, the Conversion Price of such other
      shares so

                                       99
<PAGE>

      receivable upon conversion of any such Debt Security shall be subject to
      adjustment from time to time in a manner and on terms as nearly equivalent
      as practicable to the provisions with respect to Common Stock contained in
      subparagraphs (1) through (6) of this Section 16.3, and the provisions of
      Sections 16.1, 16.2 and 16.4 through 16.9 with respect to the Common Stock
      shall apply on like or similar terms to any such other shares and the
      determination of the Board of Directors as to any such adjustment shall be
      conclusive.

            (8) No adjustment shall be made pursuant to this Section: (i) if the
      effect thereof would be to reduce the Conversion Price below the par value
      (if any) of the Common Stock or (ii) subject to 16.3(5) hereof, with
      respect to any Debt Security that is converted prior to the time such
      adjustment otherwise would be made.

      SECTION 16.4. CONSOLIDATION OR MERGER OF THE COMPANY.

      In case of either (a) any consolidation or merger to which the Company is
a party, other than a merger or consolidation in which the Company is the
surviving or continuing corporation and which does not result in a
reclassification of, or change (other than a change in par value or from par
value to no par value or from no par value to par value, as a result of a
subdivision or combination) in, outstanding shares of Common Stock or (b) any
sale or conveyance of all or substantially all of the property and assets of the
Company to another Person, then each Debt Security then outstanding shall be
convertible from and after such merger, consolidation, sale or conveyance of
property and assets into the kind and amount of shares of stock or other
securities and property (including cash) receivable upon such consolidation,
merger, sale or conveyance by a holder of the number of shares of Common Stock
into which such Debt Securities would have been converted immediately prior to
such consolidation, merger, sale or conveyance, subject to adjustments which
shall be as nearly equivalent as may be practicable to the adjustments provided
for in this Article XVI (and assuming such holder of Common Stock failed to
exercise his rights of election, if any, as to the kind or amount of securities,
cash or other property (including cash) receivable upon such consolidation,
merger, sale or conveyance (provided that, if the kind or amount of securities,
cash or other property (including cash) receivable upon such consolidation,
merger, sale or conveyance is not the same for each nonelecting share, then the
kind and amount of securities, cash or other property (including cash)
receivable upon such consolidation, merger, sale or conveyance for each
nonelecting share shall be deemed to be the kind and amount so receivable per
share by a plurality of the nonelecting shares or securities)). The Company
shall not enter into any of the transactions referred to in clause (a) or (b) of
the preceding sentence unless effective provision shall be made so as to give
effect to the provisions set forth in this Section 16.4. The provisions of this
Section 16.4 shall apply similarly to successive consolidations, mergers, sales
or conveyances.

      SECTION 16.5. NOTICE OF ADJUSTMENT.

      Whenever an adjustment in the Conversion Price with respect to a series of
Debt Securities is required:

                                      100
<PAGE>

            (1) the Company shall forthwith place on file with the Trustee and
      any Conversion Agent for such Securities a certificate of the Treasurer or
      Chief Financial Officer of the Company, stating the adjusted Conversion
      Price determined as provided herein and setting forth in reasonable detail
      such facts as shall be necessary to show the reason for and the manner of
      computing such adjustment, such certificate to be conclusive evidence that
      the adjustment is correct; and

            (2) a notice stating that the Conversion Price has been adjusted and
      setting forth the adjusted Conversion Price shall forthwith be given by
      the Company, or at the Company's request, by the Trustee in the name and
      at the expense of the Company, in the manner provided in Section 1.5. Any
      notice so given shall be conclusively presumed to have been duly given,
      whether or not the Holder receives such notice.

      SECTION 16.6. NOTICE IN CERTAIN EVENTS.

      In case:

            (1) of a consolidation or merger to which the Company is a party and
      for which approval of any shareholders of the Company is required, or of
      the sale or conveyance to another Person or entity or group of Persons or
      entities acting in concert as a partnership, limited partnership,
      syndicate or other group (within the meaning of Rule 13d-3 under the
      Securities Exchange Act of 1934, as amended) of all or substantially all
      of the property and assets of the Company; or

            (2) of the voluntary or involuntary dissolution, liquidation or
      winding up of the Company; or

            (3) of any action triggering an adjustment of the Conversion Price
      pursuant to this Article XVI,

then, in each case, the Company shall cause to be filed with the Trustee and the
Conversion Agent for the applicable Debt Securities, and shall cause to be
given, to the Holders of record of applicable Debt Securities in the manner
provided in Section 1.5, at least fifteen (15) days prior to the applicable date
hereinafter specified, a notice stating (x) the date on which a record is to be
taken for the purpose of any distribution or grant of rights or warrants
triggering an adjustment to the Conversion Price pursuant to this Article XVI,
or, if a record is not to be taken, the date as of which the holders of record
or Common Stock entitled to such distribution, rights or warrants are to be
determined, or (y) the date on which any reclassification, consolidation,
merger, sale, conveyance, dissolution, liquidation or winding up triggering an
adjustment to the Conversion Price pursuant to this Article XVI is expected to
become effective, and the date as of which it is expected that holders of Common
Stock of record shall be entitled to exchange their Common Stock for securities
or other property deliverable upon such reclassification, consolidation, merger,
sale, conveyance, dissolution, liquidation or winding up.

      Failure to give such notice or any defect therein shall not affect the
legality or validity of the proceedings described in clause (1), (2) or (3) of
this Section 16.6.

                                      101
<PAGE>

      SECTION 16.7. COMPANY TO RESERVE STOCK; REGISTRATION; LISTING.

      (a) The Company shall at all times reserve and keep available, free from
preemptive rights, out of its authorized but unissued shares of Common Stock,
for the purpose of effecting the conversion of the Debt Securities, such number
of its duly authorized shares of Common Stock as shall from time to time be
sufficient to effect the conversion of all applicable outstanding Debt
Securities into such Common Stock at any time (assuming that, at the time of the
computation of such number of shares or securities, all such Debt Securities
would be held by a single holder); provided, however, that nothing contained
herein shall preclude the Company from satisfying its obligations in respect of
the conversion of the Debt Securities by delivery of purchased shares of Common
Stock which are held in the treasury of the Company. The Company shall from time
to time, in accordance with the laws of the State of Missouri, use its best
efforts to cause the authorized amount of the Common Stock to be increased if
the aggregate of the authorized amount of the Common Stock remaining unissued
and the issued shares of such Common Stock in its treasury (other than any such
shares reserved for issuance in any other connection) shall not be sufficient to
permit the conversion of all Debt Securities.

      (b) If any shares of Common Stock which would be issuable upon conversion
of Debt Securities hereunder require registration with or approval of any
governmental authority before such shares or securities may be issued upon such
conversion, the Company will in good faith and as expeditiously as possible
endeavor to cause such shares or securities to be duly registered or approved,
as the case may be. The Company will endeavor to list the shares of Common Stock
required to be delivered upon conversion of the Debt Securities prior to such
delivery upon the principal national securities exchange upon which the
outstanding Common Stock is listed at the time of such delivery.

      SECTION 16.8. TAXES ON CONVERSION.

      The Company shall pay any and all documentary, stamp or similar issue or
transfer taxes that may be payable in respect of the issue or delivery of shares
of Common Stock on conversion of Debt Securities pursuant hereto. The Company
shall not, however, be required to pay any such tax which may be payable in
respect of any transfer involved in the issue or delivery of shares of Common
Stock or the portion, if any, of the Debt Securities which are not so converted
in a name other than that in which the Debt Securities so converted were
registered (in case of Registered Securities), and no such issue or delivery
shall be made unless and until the Person requesting such issue has paid to the
Company the amount of such tax or has established to the satisfaction of the
Company that such tax has been paid.

      SECTION 16.9. CONVERSION AFTER RECORD DATE.

      If any Debt Securities are surrendered for conversion subsequent to the
record date preceding an Interest Payment Date but on or prior to such Interest
Payment Date (except Debt Securities called for redemption on a Redemption Date
between such record date and Interest Payment Date), the Holder of such Debt
Securities at the close of business on such record date shall be entitled to
receive the interest payable on such Debt Securities on such Interest Payment
Date notwithstanding the conversion thereof. Debt Securities surrendered for
conversion during the period from the close of business on any record date next
preceding any Interest Payment

                                      102
<PAGE>

Date to the opening of business on such Interest Payment Date shall (except in
the case of Debt Securities which have been called for redemption on a
Redemption Date within such period) be accompanied by payment in New York
Clearing House funds or other funds and in the Currency acceptable to the
Company of an amount equal to the interest payable on such Interest Payment Date
on the Debt Securities being surrendered for conversion. Except as provided in
this Section 16.9, no adjustments in respect of payments of interest on Debt
Securities surrendered for conversion or any dividends or distributions of
interest on the Common Stock issued upon conversion shall be made upon the
conversion of any Debt Securities.

      SECTION 16.10. CONVERSION OF DEBT SECURITIES INTO PREFERRED SHARES OR
OTHER SECURITIES.

      Notwithstanding anything to the contrary in this Article XVI, the Company
may issue Securities that are convertible into Preferred Stock or other
securities of the Company, including Preferred Shares convertible into Common
Stock, in which case all terms and conditions relating to the conversion of
Securities into Preferred Shares or other securities, including any terms
similar to those provided in Sections 16.01 through 16.12, shall be as provided
in or pursuant to an appropriate Board Resolution or in any indenture
supplemental hereto or as otherwise contemplated by Section 3.1.

      SECTION 16.11. COMPANY DETERMINATION FINAL.

      Any determination that the Company or the Board of Directors must make
pursuant to this Article XVI is conclusive.

      SECTION 16.12. TRUSTEE'S DISCLAIMER.

      The Trustee has no duty to determine when an adjustment under this Article
XVI should be made, how it should be made or what it should be. The Trustee
makes no representation as to the validity or value of any securities or assets
issued upon conversion of Debt Securities. The Trustee shall not be responsible
for the Company's failure to comply with this Article XVI. Each Conversion Agent
other than the Company shall have the same protection under this Section as the
Trustee.

                                 ARTICLE XVII.
                                 SUBORDINATION

      SECTION 17.1. AGREEMENT TO SUBORDINATE.

      The Company agrees, and each Holder by accepting any Debt Securities
agrees, that, unless otherwise specified pursuant to Section 3.1 with respect to
any series of Debt Securities, the indebtedness evidenced by the Debt Securities
is subordinated in right of payment, to the extent and in the manner provided in
this Article XVII, to the prior payment in full of all Senior Indebtedness, and
that the subordination is for the benefit of, and shall be enforceable directly
by, the holders of Senior Indebtedness, without any act or notice of acceptance
hereof or reliance hereon.

                                      103
<PAGE>

      SECTION 17.2. CERTAIN DEFINITIONS.

      "Senior Indebtedness" means the principal, premium, if any, and interest
on (i) all indebtedness of the Company, whether outstanding on the date hereof
or thereafter created, incurred or assumed (including, without limitation, such
indebtedness issued or to be issued under the Company's Senior Indenture dated
[__], 20__), that is for borrowed money, or evidenced by a note or similar
instrument given in connection with the acquisition of any business, properties
or assets, including securities, (ii) any indebtedness of any other Person of
the kind described in the preceding clause (i) for the payment of which the
Company is responsible or liable as guarantor or otherwise and (iii) amendments,
modifications, renewals, extensions, deferrals and refundings of any such
indebtedness. Senior Indebtedness shall continue to be Senior Indebtedness and
to be entitled to the benefits of the subordination provisions of this Article
XVII irrespective of any amendment, modification or waiver of any term of the
Senior Indebtedness or extension or renewal of the Senior Indebtedness.
Notwithstanding anything to the contrary in the foregoing, Senior Indebtedness
shall not include (A) indebtedness incurred for the purchase of goods or
materials or for services obtained in the ordinary course of business and (B)
any indebtedness which by its terms is expressly made pari passu with or
subordinated to the Debt Securities.

      SECTION 17.3. LIQUIDATION; DISSOLUTION; BANKRUPTCY, ETC.

      Unless otherwise specified pursuant to Section 3.1 with respect to any
series of Debt Securities, in the event of:

            (1) any insolvency, bankruptcy, receivership, liquidation,
      reorganization, readjustment, composition or other similar proceeding
      relating to the Company, its creditors or its property;

            (2) any proceeding for the liquidation, dissolution or other winding
      up of the Company, voluntary or involuntary, whether or not involving
      insolvency or bankruptcy proceedings;

            (3) any assignment by the Company for the benefit of creditors; or

            (4) any other marshalling of the assets of the Company, all Senior
      Indebtedness (including, without limitation, interest accruing after the
      commencement of any such proceeding, assignment or marshalling of assets)
      shall first be paid in full before any payment or distribution, whether in
      cash, securities or other property, shall be made by the Company on
      account of the Debt Securities. In any such event, any payment or
      distribution, whether in cash, securities or other property (other than
      securities of the Company or any other Corporation provided for by a plan
      of reorganization or a readjustment, the payment of which is subordinate,
      at least to the extent provided in the subordination provisions of this
      Indenture with respect to the indebtedness evidenced by the Debt
      Securities, to the payment of all Senior Indebtedness at the time
      outstanding and to any securities issued in respect thereof under any such
      plan of reorganization or readjustment), which would otherwise (but for
      the

                                      104
<PAGE>

      provisions of this Article XVII) be payable or deliverable in respect of
      the Debt Securities (including any such payment or distribution which may
      be payable or deliverable by reason of the payment of any other
      indebtedness of the Company being subordinated to the payment of the Debt
      Securities) shall be paid or delivered directly to the holders of Senior
      Indebtedness, or to their representative or trustee, in accordance with
      the priorities then existing among such holders until all Senior
      Indebtedness shall have been paid in full.

      SECTION 17.4. DEFAULT ON SENIOR INDEBTEDNESS.

      Unless otherwise specified pursuant to Section 3.1 with respect to any
series of Debt Securities, if (i) the Company defaults in the payment of any
principal of (or premium, if any) or interest on any Senior Indebtedness when
the same becomes due and payable, whether at maturity or at a date fixed for
prepayment or declaration or otherwise or (ii) an event of default occurs with
respect to any Senior Indebtedness permitting the holders thereof to accelerate
the maturity thereof and written notice of such event of default (requesting
that payments on the Debt Securities cease) is given to the Company by the
holders of Senior Indebtedness, then unless and until such default in payment or
event of default shall have been cured or waived or shall have ceased to exist,
no direct or indirect payment (in cash, property or securities, by set-off or
otherwise) shall be made or agreed to be made on account of the Debt Securities
or interest thereon or in respect of any repayment, redemption, retirement,
purchase or other acquisition of the Debt Securities.

      SECTION 17.5. WHEN DISTRIBUTION MUST BE PAID OVER.

      If a distribution is made to the Trustee or any Holder at a time when a
Responsible Officer of the Trustee or such Holder has actual knowledge that
because of this Article XVII such distribution should not have been made to it,
the Trustee or such Holder who receives the distribution shall hold it in trust
for the benefit of, and, upon written request, shall pay it over to, the holders
of Senior Indebtedness as their interests may appear, or their agent or
representative or the trustee under the indenture or other agreement (if any)
pursuant to which Senior Indebtedness may have been issued, as their respective
interests may appear, for application to the payment of all principal, premium,
if any, and interest then payable with respect to any Senior Indebtedness.

      With respect to the holders of Senior Indebtedness, the Trustee undertakes
to perform only such obligations on the part of the Trustee as are specifically
set forth in this Article XVII, and no implied covenants or obligations with
respect to the holders of Senior Indebtedness shall be read into this Indenture
against the Trustee. The Trustee shall not be deemed to owe any fiduciary duty
to the holders of Senior Indebtedness, and shall not be liable to any such
holders if the Trustee shall pay over or distribute to or on behalf of Holders
or the Company or any other person money or assets to which any holders of
Senior Indebtedness shall be entitled by virtue of this Article XVII, except if
such payment is made as a result of the negligence, bad faith or willful
misconduct of the Trustee.

                                      105
<PAGE>

      SECTION 17.6. NOTICE BY COMPANY.

      The Company shall promptly notify in writing the Trustee and any Paying
Agent of any facts known to the Company that would cause a payment with respect
to the Debt Securities to violate this Article XVII, but failure to give such
notice shall not affect the subordination of the Debt Securities to the Senior
Indebtedness provided in this Article XVII.

      SECTION 17.7. SUBROGATION.

      Senior Indebtedness shall not be deemed to have been paid in full unless
the holders thereof shall have received cash, securities or other property equal
to the amount of such Senior Indebtedness then outstanding. After all Senior
Indebtedness is paid in full and until the Debt Securities are paid in full,
Holders shall be subrogated (equally and ratably with all other indebtedness as
to which the right to receive payment is pari passu with the Debt Securities) to
the rights of holders of Senior Indebtedness to receive distributions applicable
to Senior Indebtedness to the extent that distributions otherwise payable to the
Holders have been applied to the payment of Senior Indebtedness, and such
payments or distributions received by any Holder of Debt Securities of a series
(unless otherwise specified pursuant to Section 3.1 with respect to such
series), by reason of such subrogation, of cash, securities or other property
which otherwise would be paid or distributed to the holders of Senior
Indebtedness, shall, as between the Company and its creditors other than the
holders of Senior Indebtedness, on the one hand, and the Holders of Debt
Securities, on the other, be deemed to be a payment by the Company on account of
Senior Indebtedness, and not on account of such series of Debt Securities.

      SECTION 17.8. RELATIVE RIGHTS.

      This Article XVII defines the relative rights of Holders and holders of
Senior Indebtedness. Unless otherwise specified pursuant to Section 3.1 with
respect to any series of Debt Securities, nothing in this Indenture shall:

            (1) impair, as between the Company and Holders, the obligation of
      the Company, which is absolute and unconditional, to pay principal of and
      interest on the Debt Securities in accordance with their terms;

            (2) affect the relative rights of Holders and creditors of the
      Company other than their rights in relation to holders of Senior
      Indebtedness; or

            (3) prevent the Trustee or any Holder from exercising its available
      remedies upon a Default or Event of Default, subject to the rights of
      holders and owners of Senior Indebtedness to receive distributions and
      payments otherwise payable to Holders.

      If the Company fails because of this Article XVII to pay principal of or
interest on Debt Securities on the date such payment is due, the failure is
still a Default or Event of Default.

                                      106
<PAGE>

      SECTION 17.9. SUBORDINATION MAY NOT BE IMPAIRED BY COMPANY.

      No present or future holder of any Senior Indebtedness shall be prejudiced
in the right to enforce subordination of the indebtedness constituting the
applicable series of Debt Securities by any act or failure to act on the part of
the Company.

      SECTION 17.10. DISTRIBUTION.

      Upon any payment or distribution of assets of the Company referred to in
this Article XVII, the Trustee and the Holders shall be entitled to rely upon
any order or decree made by any court of competent jurisdiction or upon any
certificate of the liquidating trustee or agent or other person making any
distribution to the Trustee or to the Holders for the purpose of ascertaining
the persons entitled to participate in such distribution, the holders of the
Senior Indebtedness and other debt of the Company, the amount thereof or payable
thereon, the amount or amounts paid or distributed thereon and all other facts
pertinent thereto or to this Article XVII.

      SECTION 17.11. RIGHTS OF TRUSTEE AND PAYING AGENT.

      Notwithstanding the provisions of this Article XVII or any other provision
of this Indenture, neither the Trustee nor any Paying Agent shall be charged
with knowledge of the existence of any facts which would prohibit the making of
any payment or distribution by the Trustee or such Paying Agent, or the taking
of any action by the Trustee or such Paying Agent, and the Trustee or such
Paying Agent may continue to make payments on the Debt Securities unless, in the
case of the Trustee, and in the case of such Paying Agent as long as the Trustee
is such Paying Agent, a Responsible Officer shall have received at the Corporate
Trust Office of the Trustee, and in the case of a Paying Agent other than the
Trustee, it shall have received, in each case at least two Business Days prior
to the date of such payment, written notice of facts that would cause any such
payment with respect to the Securities to violate this Article XVII. The Trustee
or any Paying Agent, as applicable, shall promptly provide a copy of such notice
to the Holders. Nothing in this Article XVII shall limit the right of the
holders of Senior Indebtedness to recover payments as contemplated elsewhere in
this Article XVII or impair the claims of, or payments to, the Trustee under or

                            EXTENDED INTEREST PERIOD

      SECTION 18.1. EXTENSION OF INTEREST PAYMENT PERIOD.

      So long as no Event of Default has occurred and is continuing, the Company
shall have the right, at any time and from time to time during the term of the
Debt Securities of any series, to defer payments of interest by extending the
interest payment period of such Debt Securities for an Extended Interest Period
not exceeding 20 consecutive quarters, during which Extended Interest Period no
interest shall be due and payable; provided that no Extended Interest Period may
extend beyond the Stated Maturity for the principal of the Debt Securities of
such series. At the end of the Extended Interest Period, the Company shall
calculate (and deliver such calculation to the Trustee) and pay on the next
Interest Payment Date all interest accrued and unpaid on the Debt Securities of
such series, including any additional payments and additional interest accrued
thereon ("Additional Interest"), (together, the "Deferred Payments") that shall
be payable to the Holders of Registered Securities of such series on the first
Regular Record Date after the end of the Extended Interest Period. Before the
termination of any Extended Interest Period, the Company may further extend such
period, provided that such period together with all such further extensions
thereof shall not exceed 20 consecutive quarters, or extend beyond the Maturity
Date of such Debt Securities. Upon the termination of any Extended Interest
Period and upon the payment of all Deferred Payments then due, the Company may
commence a new Extended Interest Period, subject to the foregoing requirements.
No interest or Additional Interest shall be due and payable during an Extended
Interest Period, except at the end thereof, but the Company may prepay at any
time all or any portion of the interest and Additional Interest accrued during
an Extended Interest Period.

      SECTION 18.2. NOTICE OF EXTENSION.

      (a) The Company shall give the Holders of such Debt Securities and the
Trustee written notice of its selection of such Extended Interest Period at
least two Business Days before the earlier of (i) the next succeeding Interest
Payment Date; or (ii) the date the Company is required to give notice of the
record or payment date of such interest payment to The New York Stock Exchange,
Nasdaq or other applicable national exchange or self-regulatory organization or
to holders of the Debt Securities.

      (b) The quarter in which any notice is given pursuant to paragraph (a) of
this Section 18.2 shall be counted as one of the 20 quarters permitted in the
maximum Extended Interest Period permitted under Section 18.1.

      SECTION 18.3. LIMITATION ON TRANSACTIONS.

      If the Company shall exercise its right to defer payment of interest as
provided in Section 18.1, then (i) the Company shall not declare or pay any
dividend on, make any distributions with respect to, or redeem, purchase,
acquire or make a liquidation payment with respect to, any of its capital stock
(other than (A) dividends or distributions in common stock of the Company, or
any declaration of a non-cash dividend in connection with the implementation of
a shareholder rights

plan, or the issuance of stock under any such plan in the future, or the
redemption or repurchase of any such rights pursuant thereto, and (B) purchases
of common stock of the Company related to the rights under any of the Company's
benefit plans for its directors, officers or employees); (ii) the Company shall
not make any payment of principal of (and premium, if any) or interest on or
repay, repurchase or redeem any debt securities issued by the Company which rank
pari passu with or junior in interest to the Debt Securities of a series issued
under this Indenture; and (iii) the Company shall not redeem, purchase or
acquire less than all of the Outstanding Debt Securities of such series.

      SECTION 18.4. APPLICABILITY OF ARTICLE.

      Notwithstanding anything in this Indenture to the contrary, the provisions
of this Article XVIII only shall apply to Debt Securities of any series to which
this Article expressly is made applicable, as specified pursuant to Section 3.1
for any such series of Debt Securities.
