                  Section 1.3       FORM OF DOCUMENTS DELIVERED TO TRUSTEE.

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

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

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

                  Section 1.4       ACTS OF HOLDERS.

                  (a) Any request, demand, authorization, direction, notice,
         consent, waiver or other action provided by this Indenture to be given
         or taken by Holders of the Outstanding Securities of all series or one
         or more series, as the case may be, may be embodied in and evidenced by
         one or more instruments of substantially similar tenor signed by such
         Holders in person or by agents duly appointed in writing. If Securities
         of a series are issuable as Bearer Securities, any request, demand,
         authorization, direction, notice, consent, waiver or other action
         provided by this Indenture to be given or taken by Holders of such
         series may, alternatively, be embodied in and evidenced by the record
         of Holders of Securities of such series voting in favor thereof, either
         in person or by proxies duly appointed in writing, at any meeting of
         Holders of Securities of such series duly called and held in accordance
         with the provisions of Article Fifteen, or a combination of such
         instruments and any such record. Except as herein otherwise expressly
         provided, such action shall become effective when such instrument or
         instruments or record or both are delivered to the Trustee and, where
         it is hereby expressly required, to the Company. Such instrument or
         instruments and any such record (and the action embodied therein and
         evidenced thereby) are herein sometimes referred to as the "Act" of the
         Holders signing such instrument or instruments or so voting at any such
         meeting. Proof of execution of any such instrument or of a writing
         appointing any such agent, or of the holding by any Person of a
         Security, shall be sufficient for any purpose of this Indenture and
         conclusive in favor of the Trustee and the Company, if made in the
         manner provided in this Section. The record of any meeting of Holders
         of Securities shall be proved in the manner provided in Section 1506.

                  (b) The fact and date of the execution by any Person of any
         such instrument or writing may be proved by the affidavit of a witness
         of such execution or by a certificate of a notary public or other
         officer authorized by law to take acknowledgments of deeds, certifying
         that the individual


                                       12
<Page>

         signing such instrument or writing acknowledged to him the execution
         thereof. Where such execution is by a signer acting in a capacity other
         than his individual capacity, such certificate or affidavit shall also
         constitute sufficient proof of authority. The fact and date of the
         execution of any such instrument or writing, or the authority of the
         Person executing the same, may also be proved in any other manner which
         the Trustee deems sufficient.

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

                  (d) The principal amount and serial numbers of Bearer
         Securities held by any Person, and the date of holding the same, may be
         proved by the production of such Bearer Securities or by a certificate
         executed, as depositary, by any trust company, bank, banker or other
         depositary, wherever situated, if such certificate shall be deemed by
         the Trustee to be satisfactory, showing that at the date therein
         mentioned such Person had on deposit with such depositary, or exhibited
         to it, the Bearer Securities therein described; or such facts may be
         proved by the certificate or affidavit of the Person holding such
         Bearer Securities, if such certificate or affidavit is deemed by the
         Trustee to be satisfactory. The Trustee and the Company may assume that
         such ownership of any Bearer Security continues until (1) another
         certificate or affidavit bearing a later date issued in respect of the
         same Bearer Security is produced, or (2) such Bearer Security is
         produced to the Trustee by some other Person, or (3) such Bearer
         Security is surrendered in exchange for a Registered Security, or (4)
         such Bearer Security is no longer Outstanding. The principal amount and
         serial numbers of Bearer Securities held by any Person, and the date of
         holding the same, may also be proved in any other manner which the
         Trustee deems sufficient.

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

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

                  Section 1.5       NOTICES, ETC. TO TRUSTEE AND COMPANY.

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

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

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

                  Section 1.6       NOTICE TO HOLDERS; WAIVER.

                  Where this Indenture provides for notice of any event to
Holders of Registered Securities by the Company or the Trustee, such notice
shall be sufficiently given (unless otherwise herein expressly provided) if in
writing and mailed, first-class postage prepaid, to each such Holder affected by
such event, at his address as it appears in the Security Register within the
time prescribed for the giving of such notice. In any case where notice to
Holders of Registered Securities is given by mail, neither the failure to mail
such notice, nor any defect in any notice so mailed, to any particular Holder
shall affect the sufficiency of such notice with respect to other Holders of
Registered Securities or the sufficiency of any notice to Holders of Bearer
Securities given as provided. Any notice mailed to a Holder in the manner herein
prescribed shall be conclusively deemed to have been received by such Holder,
whether or not such Holder actually receives such notice.

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

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

                  In case by reason of the suspension of publication of any
Authorized Newspaper or Authorized Newspapers or by reason of any other cause it
shall be impracticable to publish any notice to Holders of Bearer Securities as
provided above, then such notification to Holders of Bearer Securities as shall
be given


                                       14
<Page>

with the approval of the Trustee shall constitute sufficient notice to such
Holders for every purpose hereunder. Neither the failure to give notice by
publication to Holders of Bearer Securities as provided above, nor any defect in
any notice so published, shall affect the sufficiency of such notice with
respect to other Holders of Bearer Securities or the sufficiency of any notice
to Holders of Registered Securities given as provided herein.

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

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

                  Section 1.7       EFFECT OF HEADINGS AND TABLE OF CONTENTS.

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

                  Section 1.8       SUCCESSORS AND ASSIGNS.

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

                  Section 1.9       SEPARABILITY CLAUSE.

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

                  Section 1.10      BENEFITS OF INDENTURE.

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

                  Section 1.11      GOVERNING LAW.

                  THIS INDENTURE AND THE SECURITIES AND COUPONS SHALL BE
GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAW OF THE STATE OF NEW YORK.
THIS INDENTURE IS SUBJECT TO THE PROVISIONS OF THE TRUST INDENTURE ACT OF 1939,

                  Section 1.12      LEGAL HOLIDAYS.

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

                  Section 1.13      TRUST INDENTURE ACT.

                  This Indenture is subject to the provisions of the Trust
Indenture Act that are required to be part of this Indenture and shall, to the
extent applicable, be governed by such provisions.

                                   ARTICLE II

                                 SECURITY FORMS

                  Section 2.1       FORMS GENERALLY.

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

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

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

                  The definitive Securities and coupons shall be printed,

Securities, as evidenced by their execution of such Securities or coupons.

                  Section 2.2       FORM OF TRUSTEE'S CERTIFICATE OF
                                    AUTHENTICATION.

                  Subject to Section 611, the Trustee's certificate of
authentication shall be in substantially the following form:

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

                                             THE BANK OF NOVA SCOTIA TRUST
                                             COMPANY OF NEW YORK,
                                             as Trustee


                                             By________________________
                                             Authorized Officer


                  Section 2.3       SECURITIES ISSUABLE IN GLOBAL FORM.

                  If Securities of or within a series are issuable in global
form, as specified as contemplated by Section 301, then, notwithstanding clause
(8) of Section 301, any such Security shall represent such of the Outstanding
Securities of such series as shall be specified therein and may provide that it
shall represent the aggregate amount of Outstanding Securities of such series
from time to time endorsed thereon and that the aggregate amount of Outstanding
Securities of such series represented thereby may from time to time be increased
or decreased to reflect exchanges. Any endorsement of a Security in global form
to reflect the amount, or any increase or decrease in the amount, of Outstanding
Securities represented thereby shall be made by the Trustee in such manner and
upon instructions given by such Person or Persons as shall be specified therein
or in the Company Order to be delivered to the Trustee pursuant to Section 303
or Section 304. Subject to the provisions of Section 303 and, if applicable,
Section 304, the Trustee shall deliver and redeliver any Security in permanent
global form in the manner and upon instructions given by the Person or Persons
specified therein or in the applicable Company Order. If a Company Order
pursuant to Section 303 or Section 304 has been, or simultaneously is,
delivered, any instructions by the Company with respect to endorsement or
delivery or redelivery of a Security in global form shall be in writing but need
not comply with Section 102 and need not be accompanied by an Opinion of
Counsel.

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

                  (20) the Person to whom any interest on any Registered

         whose name that Security (or one or more Predecessor Securities) is
         registered at the close of business on the Regular Record Date for such
         interest, the manner in which, or the Person to whom, any interest on
         any Bearer Security of the series shall be payable, if otherwise than
         upon presentation and surrender of the coupons appertaining thereto as
         they severally mature, and the extent to which, or the manner in which,
         any interest payable on a temporary global Security on an Interest

                                       20
<Page>

                  (21) if Securities of the series are to be issuable in
         definitive form (whether upon original issue or upon exchange of a
         temporary Security of such series) only upon receipt of certain
         certificates or other documents or satisfaction of other conditions,
         the form and/or terms of such certificates, documents or conditions;

                  (22) if the Securities of the series are to be issued upon the
         exercise of warrants or upon the conversion or exchange of other

         any modification to the definition of such term) in respect of any tax,
         assessment or governmental charge and, if so, whether the Company will
         have the option to redeem such Securities rather than pay such
         Additional Amounts (and the terms of any such option);

                  (24) if the Securities of the series are to be convertible
         into or exchangeable for any securities of any Person (including the
         Company), the terms and conditions upon which such Securities will be
         so convertible or exchangeable;

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

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

                  If any of the terms of the series are established by action

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.

                  All Securities shall be issuable in such denominations as
shall be specified as contem plated by Section 301. With respect to Securities

denominations of $1,000 and any integral multiple thereof and the Bearer
Securities of such Series, other than the Bearer Securities issued in global
form (which may be of any denomination), shall be issuable in a denomination of
$5,000.

                  Section 3.3       EXECUTION, AUTHENTICATION, DELIVERY AND
                                    DATING.

                  The Securities and any coupons appertaining thereto shall be
executed on behalf of the Company by its Chairman, its President or a Vice
President, under its corporate seal reproduced thereon attested by its Secretary
or an Assistant Secretary. The signature of any of these officers on the
Securities or coupons may be the manual or facsimile signatures of the present
or any future such authorized officer and may be imprinted or otherwise
reproduced on the Securities.

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

                  At any time and from time to time after the execution and
delivery of this Indenture, the Company may deliver Securities of any series
together with any coupon appertaining thereto, executed by the Company to the
Trustee for authentication, together with a Company Order for the authentication
and delivery of such Securities, and the Trustee in accordance with such Company
Order shall authenticate and deliver such Securities; PROVIDED, HOWEVER, that,
in connection with its original issuance, no Bearer Security shall be mailed or
otherwise delivered to any location in the United States; and PROVIDED FURTHER
that, unless otherwise specified with respect to any series of Securities
pursuant to Section 301, a Bearer Security may be delivered in connection with
its original issuance only if the Person entitled to receive such Bearer
Security shall have furnished a certificate in the form set forth in Exhibit A-1
to this Indenture, dated no earlier than 15 days prior to the earlier of the
date on which such Bearer Security is delivered and the date on which any
temporary Security first becomes exchangeable for such Bearer Security in
accordance with the terms of such temporary Security and this Indenture. If any
Security shall be represented by a permanent global Bearer Security, then, for
purposes of this Section and Section 304, the notation of a beneficial owner's
interest therein upon original issuance of such Security or upon exchange of a
portion of a temporary global Security shall be deemed to be delivered in
connection with its original issuance of such beneficial owner's interest in
such permanent global Security. Except as permitted by Section 306, the Trustee
shall not authenticate and deliver any Bearer Security unless all appurtenant
coupons for interest then matured have been detached and cancelled. If not all
the Securities of any series are to be issued at one time and if the Board
Resolution or supplemental indenture establishing such series shall so permit,
such Company Order may set forth procedures acceptable to the Trustee for the
issuance of such Securities and determining terms of particular Securities of
such series such as interest rate, maturity date, date of issuance and date from
which interest shall accrue.

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

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

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


                                       22
<Page>

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

                  (d) that all laws and requirements in respect of the execution
         and delivery by the Company of such Securities, any coupons and of the
         supplemental indentures, if any, have been complied with (except for
         the federal securities laws, the Trust Indenture Act of 1939, as
         amended, and the securities or blue sky laws of the various states, as
         to which no opinion need be expressed) and that authentication and
         delivery of such Securities and any coupons and the execution and
         delivery of the supplemental indenture, if any, by the Trustee will not
         violate the terms of the Indenture;

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

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

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

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

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

                  No Security or coupon shall be entitled to any benefit under
this Indenture or be valid or obligatory for any purpose unless there appears on
such Security a certificate of authentication substan tially in the form
provided for herein duly executed by the Trustee by manual signature of an
authorized officer, and such certificate upon any Security shall be conclusive
evidence, and the only evidence, that such Security has been duly authenticated
and delivered hereunder and is entitled to the benefits of this


                                       23
<Page>

Indenture. Notwithstanding the foregoing, if any Security shall have been
authenticated and delivered hereunder but never issued and sold by the Company,
and the Company shall deliver such Security to the Trustee for cancellation as
provided in Section 310 together with a written statement (which need not comply
with Section 102 and need not be accompanied by an Opinion of Counsel) stating
that such Security has never been issued and sold by the Company, for all
purposes of this Indenture such Security shall be deemed never to have been
authenticated and delivered hereunder and shall never be entitled to the
benefits of this Indenture.

                  Section 3.4       TEMPORARY SECURITIES.

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

                  Except in the case of temporary Securities in global form
(which shall be exchanged in accordance with the provisions of the following
paragraphs), if temporary Securities of any series are issued, the Company will
cause definitive Securities of that series to be prepared without unreasonable
delay. After the preparation of definitive Securities of such series, the
temporary Securities of such series shall be exchangeable for definitive
Securities of such series, upon surrender of the temporary Securities of such
series at the office or agency of the Company in a Place of Payment for that
series, without charge to the Holder. Upon surrender for cancellation of any one
or more temporary Securities of any series (accompanied by any unmatured coupons
appertaining thereto), the Company shall execute and the Trustee shall
authenticate and deliver in exchange therefor a like principal amount of
definitive Securities of the same series of authorized denominations; PROVIDED,
HOWEVER, that no definitive Bearer Security shall be delivered in exchange for a
temporary Registered Security; and PROVIDED FURTHER that a definitive Bearer
Security shall be delivered in exchange for a temporary Bearer Security only in
compliance with the conditions set forth in Section 303. Until so exchanged the
temporary Securities of any series shall in all respects be entitled to the same
benefits under this Indenture as definitive Securities of such series.

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

                  Without unnecessary delay, but in any event not later than the
date specified in, or determined pursuant to the terms of, any such temporary
global Security (the "Exchange Date"), the Company shall deliver to the Trustee
definitive Securities, in aggregate principal amount equal to the principal
amount of such temporary global Security, executed by the Company. On or after
the Exchange Date such temporary global Security shall be surrendered by the
Common Depositary to the Trustee, as the Company's agent for such purpose, to be
exchanged, in whole or from time to time in part, for definitive Securities
without charge and the Trustee shall authenticate and deliver, in exchange for
each


                                       24
<Page>

portion of such temporary global Security, an equal aggregate principal amount
of definitive Securities of the same series of authorized denominations and of
like tenor as the portion of such temporary global Security to be exchanged. The
definitive Securities to be delivered in exchange for any such temporary global
Security shall be in bearer form, registered form, permanent global bearer form
or permanent global registered form, or any combination thereof, as specified as
contemplated by Section 301, and, if any combination thereof is so specified, as
requested by the beneficial owner thereof; PROVIDED, HOWEVER, that, unless
otherwise specified in such temporary global Security, upon such presentation by
the Common Depositary, such temporary global Security is accompanied by a
certificate dated the Exchange Date or a subsequent date and signed by Euroclear
as to the portion of such temporary global Security held for its account then to
be exchanged and a certificate dated the Exchange Date or a subsequent date and
signed by CEDEL S.A. as to the portion of such temporary global Security held
for its account then to be exchanged, each in the form set forth in Exhibit A-2
to this Indenture (or in such other form as may be established pursuant to
Section 301); and PROVIDED FURTHER that definitive Bearer Securities shall be
delivered in exchange for a portion of a temporary global Security only in
compliance with the require ments of Section 303.

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

                  Until exchanged in full as hereinabove provided, the temporary
Securities of any series shall in all respects be entitled to the same benefits
under this Indenture as definitive Securities of the same series and of like
tenor authenticated and delivered hereunder, except that, unless otherwise
specified as contemplated by Section 301, interest payable on a temporary global
Security on an Interest Payment Date for Securities of such series occurring
prior to the applicable Exchange Date shall be payable to Euroclear and CEDEL
S.A. on such Interest Payment Date upon delivery by Euroclear and CEDEL S.A. to
the Trustee of a certificate or certificates in the form set forth in Exhibit
A-2 to this Indenture (or in such other form as may be established pursuant to
Section 301), for credit without further interest on or after such Interest
Payment Date to the respective accounts of the Persons who are the beneficial
owners of such temporary global Security on such Interest Payment Date and who
have each delivered to Euroclear or CEDEL S.A., as the case may be, a
certificate dated no earlier than 15 days prior to the Interest Payment Date
occurring prior to such Exchange Date in the form set forth in Exhibit A-1 to
this Indenture (or in such other form as may be established pursuant to Section
301). Notwith standing anything to the contrary herein contained, the
certifications made pursuant to this paragraph shall satisfy the certification
requirements of the preceding two paragraphs of this Section and of the third
paragraph of Section 303 of this Indenture and the interests of the Persons who
are the beneficial owners


                                       25
<Page>

of the temporary global Security with respect to which such certification was
made will be exchanged for definitive Securities of the same series and of like
tenor on the Exchange Date or the date of certification if such date occurs
after the Exchange Date, without further act or deed by such beneficial owners.
Except as otherwise provided in this paragraph, no payments of principal or
interest owing with respect to a beneficial interest in a temporary global
Security will be made unless and until such interest in such temporary global
Security shall have been exchanged for an interest in a definitive Security. Any
interest so received by Euroclear and CEDEL S.A. and not paid as herein provided
shall be returned to the Trustee immediately prior to the expiration of two
years after such Interest Payment Date in order to be repaid to the Company in
accordance with Section 1003.

                  Section 3.5       REGISTRATION, REGISTRATION OF TRANSFER AND
                                    EXCHANGE.

                  The Company shall cause to be kept at the Corporate Trust
Office of the Trustee a register for each series of Securities (the registers
maintained in the Corporate Trust Office of the Trustee 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 of Registered Securities.
The Security Register shall be in written form or any other form capable of
being converted into written form within a reasonable time. At all reasonable
times, the Security Register shall be open to inspection by the Trustee. The
Trustee is hereby initially appointed as security registrar (the "Security
Registrar") for the purpose of registering Registered Securities and transfers
of Registered Securities as herein provided.

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

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

                  If (but only if) expressly permitted in or pursuant to the
applicable Board Resolution and (subject to Section 303) set forth in the
applicable Officers' Certificate, or in any indenture supplemental hereto,
delivered as contemplated by Section 301, at the option of the Holder, Bearer
Securities of any series may be exchanged for Registered Securities of the same
series of any authorized denomination and of a like aggregate principal amount
and tenor, upon surrender of the Bearer Securities to be exchanged at any such
office or agency, with all unmatured coupons and all matured coupons in default
thereto appertaining. If the Holder of a Bearer Security is unable to produce
any such unmatured coupon or coupons or matured coupon or coupons in default,
any such permitted exchange may be effected if the Bearer Securities are
accompanied by payment in funds acceptable to the Company in an amount equal to
the face amount of such missing coupon or coupons, or the surrender of such
missing coupon or coupons may be waived by the Company and the Trustee if there
is furnished to them such security or indemnity


                                       26
<Page>

as they may require to save each of them and any Paying Agent harmless. If
thereafter the Holder of such Security shall surrender to any Paying Agent any
such missing coupon in respect of which such a payment shall have been made,
such Holder shall be entitled to receive the amount of such payment; PROVIDED,
HOWEVER, that, except as otherwise provided in Section 1002, interest
represented by coupons shall be payable only upon presentation and surrender of
those coupons at an office or agency located outside the United States.
Notwithstanding the foregoing, in case a Bearer Security of any series is
surrendered at any such office or agency in a permitted exchange for a
Registered Security of the same series and like tenor after the close of
business at such office or agency on (i) any Regular Record Date and before the
opening of business at such office or agency on the relevant Interest Payment
Date, or (ii) any Special Record Date and before the opening of business at such
office or agency on the related proposed date for payment of Defaulted Interest,
such Bearer Security shall be surrendered without the coupon relating to such
Interest Payment Date or proposed date for payment, as the case may be, and
interest or Defaulted Interest, as the case may be, will not be payable on such
Interest Payment Date or proposed date for payment, as the case may be, in
respect of the Registered Security issued in exchange for such Bearer Security,
but will be payable only to the Holder of such coupon when due in accordance
with the provisions of this Indenture.

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

                  Notwithstanding the foregoing, except as otherwise specified
as contemplated by Section 301, any permanent global Security shall be
exchangeable only as provided in this paragraph. If any beneficial owner of an
interest in a permanent global Security is entitled to exchange such interest
for Securities of such series and of like tenor and principal amount of another
authorized form and denomi nation, as specified as contemplated by Section 301
and provided that any applicable notice provided in the permanent global
Security shall have been given, then without unnecessary delay but in any event
not later than the earliest date on which such interest may be so exchanged, the
Company shall deliver to the Trustee definitive Securities in aggregate
principal amount equal to the principal amount of such beneficial owner's
interest in such permanent global Security, executed by the Company. On or after
the earliest date on which such interests may be so exchanged, such permanent
global Security shall be surrendered by the Common Depositary or such other
depositary as shall be specified in the Company Order with respect thereto to
the Trustee, as the Company's agent for such purpose, to be exchanged, in whole
or from time to time in part, for definitive Securities without charge, and the
Trustee shall authenticate and deliver, in exchange for each portion of such
permanent global Security, an equal aggregate principal amount of definitive
Securities of the same series of authorized denominations and of like tenor as
the portion of such permanent global Security to be exchanged which, unless the
Securities of the series are not issuable both as Bearer Securities and as
Registered Securities, as specified as contemplated by Section 301, shall be in
the form of Bearer Securities or Registered Securities, or any combination
thereof, as shall be specified by the beneficial owner thereof; PROVIDED,
HOWEVER, that no such exchanges may occur during a period beginning at the
opening of business 15 days before any selection of Securities to be redeemed
and ending on the relevant Redemption Date if the Security for which exchange is
requested may be among those selected for redemption; and PROVIDED FURTHER that
no Bearer Security delivered in exchange for a portion of a permanent global
Security shall be mailed or otherwise delivered to any location in the United
States. If a Registered Security is issued in exchange for any portion of a
permanent global Security after the close of business at the office or agency
where such exchange occurs on (i) any Regular Record Date and before the opening
of business at such office or


                                       27
<Page>

agency on the relevant Interest Payment Date, or (ii) any Special Record Date
and the opening of business at such office or agency on the related proposed
date for payment of interest or Defaulted Interest, as the case may be, will not
be payable on such Interest Payment Date or proposed date for payment, as the
case may be, in respect of such Registered Security, but will be payable on such
Interest Payment Date or proposed date for payment, as the case may be, only to
the Person to whom interest in respect of such portion of such permanent global
Security is payable in accordance with the provisions of this Indenture.

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

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

                  No service charge shall be made for any registration of
transfer or exchange of Securities, but the Company may require payment of a sum
sufficient to cover any tax or other governmental charge that may be imposed in
connection with any registration of transfer or exchange of Securities, other
than exchanges pursuant to Section 304, 906, 1107 or 1305 not involving any
transfer.

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

                  Section 3.6       MUTILATED, DESTROYED, LOST AND STOLEN
                                    SECURITIES.

                  If any mutilated Security or a Security with a mutilated
coupon appertaining to it is surrendered to the Trustee, the Company shall
execute and the Trustee shall authenticate and deliver in exchange therefor a
new Security of the same series and of like tenor and principal amount and
bearing a number not contemporaneously outstanding, with coupons corresponding
to the coupons, if any, appertaining to the surrendered Security, or, in case
any such mutilated Security or coupon has become or is about to become due and
payable, the Company in its discretion may, instead of issuing a new Security,
with coupons corresponding to the coupons, if any, appertaining to the
surrendered Security, pay such Security or coupon.


                                       28
<Page>

                  If there shall be delivered to the Company and to the Trustee
(i) evidence to their satisfaction of the destruction, loss or theft of any
Security or coupon and (ii) such security or indemnity as may be required by
them to save each of them and any agent of either of them harmless, then, in the
absence of notice to the Company or the Trustee that such Security or coupon has
been acquired by a bona fide purchaser, the Company shall execute and upon
Company Order the Trustee shall authenticate and deliver, in lieu of any such
destroyed, lost or stolen Security or in exchange for the Security for which a
destroyed, lost or stolen coupon appertains (with all appurtenant coupons not
destroyed, lost or stolen), a new Security of the same series and of like tenor
and principal amount and bearing a number not contemporaneously outstanding,
with coupons corresponding to the coupons, if any, appertaining to such
destroyed, lost or stolen Security or to the Security to which such destroyed,
lost or stolen coupon appertains, or, in case any such destroyed, lost or stolen
Security or coupon has become or is about to become due and payable, the Company
in its discretion may, instead of issuing a new Security, with coupons
corresponding to the coupons, if any, appertaining to such destroyed, lost or
stolen Security or to the Security to which such destroyed, lost or stolen
coupon appertains, pay such Security or coupon.

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

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

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

                  Section 3.7       PAYMENT OF INTEREST; INTEREST RIGHTS
                                    PRESERVED; OPTIONAL INTEREST RESET.

                  (a) Unless otherwise provided as contemplated by Section 301
         with respect to any series of Securities, 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 Security (or one or more Predecessor Securities) is registered at
         the close of business on the Regular Record Date for such interest at
         the office or agency of the Company maintained for such purpose
         pursuant to Section 1002; PROVIDED, HOWEVER, that each installment of
         interest on any Registered Security may at the Company's option be paid
         by (i) mailing a check for such interest, payable to or upon the
         written order of the Person entitled thereto pursuant to Section 309,
         to the address of such Person as it appears on the Security Register or
         (ii) transfer to an account maintained by the payee located in the
         United States.


                                       29
<Page>

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

                  Unless otherwise provided as contemplated by Section 301,
every permanent global Security will provide that interest, if any, payable on
any Interest Payment Date will be paid to each of Euroclear and CEDEL S.A. with
respect to that portion of such permanent global Security held for its account
by the Common Depositary, for the purpose of permitting each of Euroclear and
CEDEL S.A. to credit the interest received by it in respect of such permanent
global Security to the accounts of the beneficial owners thereof.

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

                  (1) The Company may elect to make payment of any Defaulted
         Interest to the Persons in whose names the Registered Securities of
         such series (or their respective Predecessor Securities) are registered
         at the close of business on a Special Record Date for the payment of
         such Defaulted Interest, which shall be fixed in the following manner.
         The Company shall notify the Trustee in writing of the amount of
         Defaulted Interest proposed to be paid on each Registered Security of
         such series and the date of the proposed payment, and at the same time
         the Company shall deposit with the Trustee an amount of money in the
         Currency in which the Securities of such series are payable (except as
         otherwise specified pursuant to Section 301 for the Securities of such
         series and except, if applicable, as provided in Sections 312(b),
         312(d) and 312(e)) equal to the aggregate amount proposed to be paid in
         respect of such Defaulted Interest or shall make arrange ments
         satisfactory to the Trustee for such deposit on or prior to the date of
         the proposed payment, such money when deposited to be held in trust for
         the benefit of the Persons entitled to such Defaulted Interest as in
         this clause provided. Thereupon the Trustee shall fix a Special Record
         Date for the payment of such Defaulted Interest which shall be not more
         than 15 days and not less than 10 days prior to the date of the
         proposed payment and not less than 10 days after the receipt by the
         Trustee of the notice of the proposed pay ment. The Trustee shall
         promptly notify the Company of such Special Record Date and, in the
         name and at the expense of the Company, shall cause notice of the
         proposed payment of such Defaulted Interest and the Special Record Date
         therefor to be given in the manner provided in Section 106, not less
         than 10 days prior to such Special Record Date. Notice of the proposed
         payment of such Defaulted Interest and the Special Record Date therefor
         having been so given, such Defaulted Interest shall be paid to the
         Persons in whose name the Registered Securities of such series (or
         their respective Predecessor Securities) are registered at the close of
         business on such Special Record Date and shall no longer be payable
         pursuant to the following clause (2).


                                       30
<Page>

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

                  (b) The provisions of this Section 307(b) may be made
         applicable to any series of Securities pursuant to Section 301 (with
         such modifications, additions or substitutions as may be specified
         pursuant to such Section 301). The interest rate (or the spread or
         spread multiplier used to calculate such interest rate, if applicable)
         on any Security of such series may be reset by the Company on the date
         or dates specified on the face of such Security (each an "Optional
         Reset Date"). The Company may exercise such option with respect to such
         Security by notifying the Trustee of such exercise at least 50 but not
         more than 60 days prior to an Optional Reset Date for such Note. Not
         later than 40 days prior to each Optional Reset Date, the Trustee shall
         transmit, in the manner provided for in Section 106, to the Holder of
         any such Security a notice (the "Reset Notice") indicating whether the
         Company has elected to reset the interest rate (or the spread or spread
         multiplier used to calculate such interest rate, if applicable), and if
         so (i) such new interest rate (or such new spread or spread multiplier,
         if applicable) and (ii) the provisions, if any, for redemption during
         the period from such Optional Reset Date to the next Optional Reset
         Date or if there is no such next Optional Reset Date, to the Stated
         Maturity Date of such Security (each such period a "Subsequent Interest
         Period"), including the date or dates on which or the period or periods
         during which and the price or prices at which such redemption may occur
         during the Subsequent Interest Period.

                  Notwithstanding the foregoing, not later than 20 days prior to
the Optional Reset Date, the Company may, at its option, revoke the interest
rate (or the spread or spread multiplier used to calculate such interest rate,
if applicable) provided for in the Reset Notice and establish an interest rate
(or a spread or spread multiplier used to calculate such interest rate, if
applicable) that is higher than the interest rate (or the spread or spread
multiplier, if applicable) provided for in the Reset Notice, for the Subsequent
Interest Period by causing the Trustee to transmit, in the manner provided for
in Section 106, notice of such higher interest rate (or such higher spread or
spread multiplier, if applicable) to the Holder of such Security. Such notice
shall be irrevocable. All Securities with respect to which the interest rate (or
the spread or spread multiplier used to calculate such interest rate, if
applicable) is reset on an Optional Reset Date, and with respect to which the
Holders of such Securities have not tendered such Securities for repayment (or
have validly revoked any such tender) pursuant to the next succeeding paragraph,
will bear such higher interest rate (or such higher spread or spread multiplier,
if applicable).

                  The Holder of any such Security will have the option to elect
repayment by the Company of the principal of such Security on each Optional
Reset Date at a price equal to the principal amount thereof plus interest
accrued to such Optional Reset Date. In order to obtain repayment on an Optional
Reset Date, the Holder must follow the procedures set forth in Article Thirteen
for repayment at the option of Holders except that the period for delivery or
notification to the Trustee shall be at least 25 but not more than 35 days prior
to such Optional Reset Date and except that, if the Holder has tendered any
Security for repayment pursuant to the Reset Notice, the Holder may, by written
notice to the Trustee, revoke such tender or repayment until the close of
business on the tenth day before such Optional Reset Date.

<Page>

                  Subject to the foregoing provisions of this Section and
Section 305, each Security delivered under this Indenture upon registration of
transfer of or in exchange for or in lieu of any other Security shall carry the
rights to interest accrued and unpaid, and to accrue, which were carried by such
other Security.

                  Section 3.8       OPTIONAL EXTENSION OF STATED MATURITY.

                  The provisions of this Section 308 may be made applicable to
any series of Securities pursuant to Section 301 (with such modifications,
additions or substitutions as may be specified pursuant to such Section 301).
The Stated Maturity of any Security of such series may be extended at the option
of the Company for the period or periods specified on the face of such Security
(each an "Extension Period") up to but not beyond the date (the "Final
Maturity") set forth on the face of such Security. The Company may exercise such
option with respect to any Security by notifying the Trustee of such exercise at
least 50 but not more than 60 days prior to the Stated Maturity of such Security
in effect prior to the exercise of such option (the "Original Stated Maturity").
If the Company exercises such option, the Trustee shall transmit, in the manner
provided for in Section 106, to the Holder of such Security not later than 40
days prior to the Original Stated Maturity a notice (the "Extension Notice")
indicating (i) the election of the Company to extend the Stated Maturity, (ii)
the new Stated Maturity, (iii) the interest rate applicable to the Extension
Period and (iv) the provisions, if any, for redemption during such Extension
Period. Upon the Trustee's transmittal of the Extension Notice, the Stated
Maturity of such Security shall be extended automatically and, except as
modified by the Extension Notice and as described in the next paragraph, such
Security will have the same terms as prior to the transmittal of such Extension
Notice.

                  Notwithstanding the foregoing, not later than 20 days before
the Original Stated Maturity of such Security, the Company may, at its option,
revoke the interest rate provided for in the Extension Notice and establish a
higher interest rate for the Extension Period by causing the Trustee to
transmit, in the manner provided for in Section 106, notice of such higher
interest rate to the Holder of such Security. Such notice shall be irrevocable.
All Securities with respect to which the Stated Maturity is extended will bear
such higher interest rate.

                  If the Company extends the Maturity of any Security, the
Holder will have the option to elect repayment of such Security by the Company
on the Original Stated Maturity at a price equal to the principal amount
thereof, plus interest accrued to such date. In order to obtain repayment on the
Original Stated Maturity once the Company has extended the Maturity thereof, the
Holder must follow the procedures set forth in Article Thirteen for repayment at
the option of Holders, except that the period for delivery or notification to
the Trustee shall be at least 25 but not more than 35 days prior to the Original
Stated Maturity and except that, if the Holder has tendered any Security for
repayment pursuant to an Extension Notice, the Holder may by written notice to
the Trustee revoke such tender for repayment until the close of business on the
tenth day before the Original Stated Maturity.

                  Section 3.9       PERSONS DEEMED OWNERS.

                  Prior to due presentment of a Registered Security for
registration of transfer, the Company, the Trustee and any agent of the Company
or the Trustee may treat the Person in whose name such Registered Security is
registered as the owner of such Registered Security for the purpose of receiving
payment of principal of (and premium, if any, on) and (subject to Sections 305
and 307) interest on such Security and for all other purposes whatsoever,
whether or not such Security be overdue, and


                                       32

none of the Company, the Trustee or any agent of the Company or the Trustee
shall be affected by notice to the contrary.

                  Title to any Bearer Security and any coupons appertaining
thereto shall pass by delivery. The Company, the Trustee and any agent of the
Company or the Trustee may treat the bearer of any Bearer Security and the
bearer of any coupon as the absolute owner of such Security or coupon for the
purpose of receiving payment thereof or on account thereof and for all other
purposes whatsoever, whether or not such Security or coupons be overdue, and
none of the Company, the Trustee or any agent of the Company or the Trustee
shall be affected by notice to the contrary.

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

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

                  Section 3.10      CANCELLATION.

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

                  Section 3.11      COMPUTATION OF INTEREST.

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

                  Section 3.12      CURRENCY AND MANNER OF PAYMENTS IN RESPECT
                                    OF SECURITIES.

                  (a) Unless otherwise specified with respect to any Securities
         pursuant to Section 301, with respect to Registered Securities of any
         series not permitting the election provided for in paragraph (b) below
         or the Holders of which have not made the election provided for in
         paragraph (b) below, and with respect to Bearer Securities of any
         series, except as provided in paragraph (d) below, payment of the
         principal of (and premium, if any, on) and interest, if any, on any
         Regis tered or Bearer Security of such series will be made in the
         Currency in which such Registered Security or Bearer Security, as the
         case may be, is payable. The provisions of this Section 312 may be
         modified or superseded with respect to any Securities pursuant to
         Section 301.

                  (b) It may be provided pursuant to Section 301 with respect to
         Registered Securities of any series that Holders shall have the option,
         subject to paragraphs (d) and (e) below, to receive payments of
         principal of (and premium, if any, on) or interest, if any, on such
         Registered Securities in any of the Currencies which may be designated
         for such election by delivering to the Trustee a written election with
         signature guarantees and in the applicable form established pursuant to
         Section 301, not later than the close of business on the Election Date
         immediately preceding the applicable payment date. If a Holder so
         elects to receive such payments in any such Currency, such election
         will remain in effect for such Holder or any transferee of such Holder
         until changed by such Holder or such transferee by written notice to
         the Trustee (but any such change must be made not later than the close
         of business on the Election Date immediately preceding the next payment
         date to be effective for the payment to be made on such payment date
         and no such change of election may be made with respect to payments to
         be made on any Registered Security of such series with respect to which
         an Event of Default has occurred or with respect to which the Company
         has deposited funds pursuant to Article Four or with respect to which a
         notice of redemption has been given by the Company or a notice of
         option to elect repayment has been sent by such Holder or such
         transferee). Any Holder of any such Registered Security who shall not
         have delivered any such election to the Trustee not later than the
         close of business on the applicable Election Date will be paid the
         amount due on the applicable payment date in the relevant Currency as
         provided in Section 312(a). The Trustee shall notify the Exchange Rate
         Agent as soon as practicable after the Election Date of the aggregate
         principal amount of Registered Securities for which Holders have made
         such written election.

                  (c) Unless otherwise specified pursuant to Section 301, if the
         election referred to in paragraph (b) above has been provided for
         pursuant to Section 301, then, unless otherwise specified pursuant to
         Section 301, not later than the fourth Business Day after the Election
         Date for each payment date for Registered Securities of any series, the
         Exchange Rate Agent will deliver to the Company a written notice
         specifying, in the Currency in which Registered Securi ties of such
         series are payable, the respective aggregate amounts of principal of
         (and premium, if any, on) and interest, if any, on the Registered
         Securities to be paid on such payment date, specifying the amounts in
         such Currency so payable in respect of the Registered Securities as to
         which the Holders of Registered Securities of such series shall have
         elected to be paid in another Currency as provided in paragraph (b)
         above. If the election referred to in paragraph (b) above has been
         provided for pursuant to Section 301 and if at least one Holder has
         made such election, then, unless otherwise specified pursuant to
         Section 301, on the second Business Day preceding such payment date the
         Company will deliver to the Trustee for such series of Registered
         Securi ties an Exchange Rate Officer's Certificate in respect of the
         Dollar or Foreign Currency payments


                                       34
<Page>

         to be made on such payment date. Unless otherwise specified pursuant to
         Section 301, the Dollar or Foreign Currency amount receivable by
         Holders of Registered Securities who have elected payment in a Currency
         as provided in paragraph (b) above shall be determined by the Company
         on the basis of the applicable Market Exchange Rate in effect on the
         third Business Day (the "Valuation Date") immediately preceding each
         payment date, and such determination shall be conclusive and binding
         for all purposes, absent manifest error.

                  (d) If a Currency Conversion Event occurs with respect to a
         Foreign Currency in which any of the Securities are denominated or
         payable other than pursuant to an election provided for pursuant to
         paragraph (b) above, then with respect to each date for the payment of
         principal of (and premium, if any, on) and interest, if any, on the
         applicable Securities denomi nated or payable in such Foreign Currency
         occurring after the last date on which such Foreign Currency was used
         (the "Currency Conversion Date"), the Dollar shall be the Currency of
         payment for use on each such payment date. Unless otherwise specified
         pursuant to Section 301, 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 Securities with respect to such payment date shall be, in the case
         of a Foreign Currency other than a currency unit, 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
         Exchange Rate Agent in the manner provided in paragraph (f) or (g)
         below.

                  (e) Unless otherwise specified pursuant to Section 301, if the
         Holder of a Registered Security denominated in any Currency shall have
         elected to be paid in another Currency as provided in paragraph (b)
         above, and a Currency 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; and
         if a Currency 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
         (d) above.

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

                  (g) The "Dollar Equivalent of the Currency Unit" shall be
         determined by the Exchange Rate Agent and subject to the provisions of
         paragraph (h) 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.

                  (h) For purposes of this Section 312 the following terms shall
         have the following meanings:

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


                                       35
<Page>

                  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 Currency Conversion Date. If after the
         Currency 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 Currency 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 Currency 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, having an aggregate Dollar Equivalent value at
         the Market Exchange Rate on the date of such replacement equal to the
         Dollar Equivalent value of the Specified Amount of such former
         Component Currency at the Market Exchange Rate immediately before such
         division and such amounts shall thereafter be Specified Amounts and
         such currencies shall thereafter be Component Currencies. If, after the
         Currency Conversion Date of the relevant currency unit, including, but
         not limited to, the ECU, a Currency 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 and
         is continuing on the applicable Valuation Date, 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 Currency Conversion Date of such
         Component Currency.

                  "Election Date" shall mean the date for any series of
         Registered Securities as specified pursuant to clause (13) of Section
         301 by which the written election referred to in paragraph (b) above
         may be made.

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

                  In the event that the Company determines in good faith that a
Currency Conversion Event has occurred with respect to a Foreign Currency, the
Company will immediately give written notice thereof to the Trustee and to the
Exchange Rate Agent (and the Trustee will promptly thereafter give notice in the
manner provided for in Section 106 to the affected Holders) specifying the
Currency Conversion Date. In the event the Company so determines that a Currency
Conversion Event has occurred with respect to the ECU or any other currency unit
in which Securities are denominated or payable, the Company will immediately
give written notice thereof to the Trustee and to the Exchange Rate Agent (and
the Trustee will promptly thereafter give notice in the manner provided for in
Section 106 to the affected Holders) specifying the Currency Conversion Date and
the Specified Amount of each Component Currency on the Currency Conversion Date.
In the event the Company determines in good


                                       36
<Page>

faith that any subsequent change in any Component Currency as set forth in the
definition of Specified Amount above has occurred, the Company will similarly
give written notice to the Trustee and the Exchange Rate Agent.

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

                  Section 3.13      APPOINTMENT AND RESIGNATION OF SUCCESSOR
                                    EXCHANGE RATE AGENT.

                  (a) Unless otherwise specified pursuant to Section 301, if and
         so long as the Securities of any series (i) are denominated in a
         Currency other than Dollars or (ii) may be payable in a Currency other
         than Dollars, or so long as it is required under any other provision of
         this Indenture, then the Company will maintain with respect to each
         such series of Securities, or as so required, at least one Exchange
         Rate Agent. The Company will cause the Exchange Rate Agent to make the
         necessary foreign exchange determinations at the time and in the manner
         specified pursuant to Section 301 for the purpose of determining the
         applicable rate of exchange and, if applicable, for the purpose of
         converting the issued Currency into the applicable payment Currency for
         the payment of principal (and premium, if any) and interest, if any,
         pursuant to Section 312.

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

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

                  Section 3.14      DESIGNATION AS SENIOR INDEBTEDNESS.

                  The Company hereby confirms the designation of the Securities
as "Senior Indebtedness" for the purposes of any securities of the Company that
may be issued pursuant to the Subordinated Indenture.

                  This Indenture shall upon Company Request cease to be of
further effect with respect to any series of Securities (except as to any
surviving rights of registration of transfer or exchange of Securities of such
series herein expressly provided for and the obligation of the Company to pay
any Additional Amounts as contemplated by Section 1005) and the Trustee, at the
expense of the Company, shall execute proper instruments acknowledging

                  Section 5.2       ACCELERATION OF MATURITY; RESCISSION AND
                                    ANNULMENT.

                  If an Event of Default described in clause (1), (2), (3), (4),
(7) or (8) of Section 501 with respect to Securities of any series at the time
Outstanding occurs and is continuing, then in every such case the Trustee or the
Holders of not less than 25% in principal amount of the Outstanding Securities
of that series may declare the principal amount (or, if the Securities of that
series are Original Issue Discount Securities or Indexed Securities, such
portion of the principal amount as may be specified in the terms of


                                       40
<Page>

that series) of all of the Securities of that 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
portion thereof) shall become immediately due and payable. If an Event of
Default described in clause (5) or (6) of Section 501 occurs and is continuing,
then the principal amount of all the Debt Securities shall IPSO FACTO become and
be immediately due and payable without declaration or other act on the part of
the Trustee or any Holder.

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

                  (1) the Company has paid or deposited with the Trustee a sum
         sufficient to pay in the Currency in which the Securities of such
         series are payable (except as otherwise specified pursuant to Section
         301 for the Securities of such series and except, if applica ble, as
         provided in Sections 312(b), 312(d) and 312(e)),

                           (A) all overdue interest on all Outstanding
                  Securities of that series (or of all series, as the case may
                  be) and any related coupons,

                           (B) all unpaid principal of (and premium, if any, on)
                  any Outstanding Securi ties of that series (or of all series,
                  as the case may be) which has become due otherwise than by
                  such declaration of acceleration, and interest on such unpaid
                  principal at the rate or rates prescribed therefor in such
                  Securities,

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

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

                  (2) all Events of Default with respect to Securities of that
         series (or of all series, as the case may be), other than the
         non-payment of amounts of principal of (or premium, if any, on) or
         interest on Securities of that series (or of all series, as the case
         may be) which have become due solely by such declaration of
         acceleration, have been cured or waived as provided in Section 513.

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

                  Notwithstanding the preceding paragraph, in the event of a
declaration of acceleration in respect of the Securities because of an Event of
Default specified in Section 501(7) shall have occurred and be continuing, such
declaration of acceleration shall be automatically annulled if the Debt that is
the subject of such Event of Default has been discharged or the holders thereof
have rescinded their declaration of acceleration in respect of such Debt, and
written notice of such discharge or rescission, as


                                       41
<Page>

the case may be, shall have been given to the Trustee by the Company and
countersigned by the holders of such Debt or a trustee, fiduciary or agent for
such holders, within 30 days after such declaration of acceleration in respect
of the Securities, and no other Event of Default has occurred during such 30-day
period which has not been cured or waived during such period.

                  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 Security and any related coupon when such interest
         becomes due and payable and such default continues for a period of 30
         days, or

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

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

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

                  If an Event of Default with respect to Securities of any
series (or of all series, as the case may be) occurs and is continuing, the
Trustee may in its discretion proceed to protect and enforce its rights and the
rights of the Holders of Securities of such series (or of all series, as the
case may be) 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 proceeding relative to the Company or any other obligor upon the
Securities or the property of the Company or of such other obligor or their
creditors, the Trustee (irrespective of whether the principal of the Securities
shall then be due and payable as therein expressed or by declaration or
otherwise and irrespective of whether the Trustee shall have made any demand on
the Company for the payment of overdue principal, premium, if any, or interest)
shall be entitled and empowered, by intervention in such proceeding or
otherwise,


                                       42

                  (i) to file and prove a claim for the whole amount of
         principal (and premium, if any), or such portion of the principal
         amount of any series of Original Issue Discount Securities or Indexed
         Securities as may be specified in the terms of such series, and
         interest owing and unpaid in respect of the Securities and to file such
         other papers or documents as may be necessary or advisable in order to
         have the claims of the Trustee (including any claim for the reasonable
         compensation, expenses, disbursements and advances of the Trustee, its
         agents and counsel) and of the Holders allowed in such judicial
         proceeding, and

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

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or
other similar official in any such judicial proceeding is hereby authorized by
each Holder to make such payments to the Trustee and, in the event that the
Trustee shall consent to the making of such payments directly to the Holders, to
pay 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 606.

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

                  Section 5.5       TRUSTEE MAY ENFORCE CLAIMS WITHOUT
                                    POSSESSION OF SECURITIES.

                  All rights of action and claims under this Indenture or the
Securities or coupons may be prosecuted and enforced by the Trustee without the
possession of any of the Securities or coupons or the production thereof in any
proceeding relating thereto, and any such proceeding instituted by the Trustee
shall be brought in its own name as trustee of an express trust, and any
recovery of judgment shall, after provision for the payment of the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel, be for the ratable benefit of the Holders of the Securities and
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
shall be applied in the following order, at the date or dates fixed by the
Trustee and, in case of the distribution of such money on account of principal
(or premium, if any) or interest, upon presentation of the Securities or
coupons, or both, as the case may be, and the notation thereon of the payment if
only partially paid and upon surrender thereof if fully paid:

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

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

         kind, according to the amounts due and payable on such Securities and
         coupons for principal (and premium, if any) and interest, respectively;
         and

                  THIRD: The balance, if any, to the Person or Persons entitled
         thereto including, without limitation, the Company.

                  Section 5.7       LIMITATION ON SUITS.

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

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

                  (2) the Holders of not less than 25% in principal amount of
         the Outstanding Securities of that series in the case of any Event of
         Default described in clause (1), (2), (3), (4), (7) or (8) of Section
         501, or, in the case of any Event of Default described in clause (5) or
         (6) of Section 501, the Holders of not less than 25% in principal
         amount of all Outstanding Securities, shall have made written request
         to the Trustee to institute proceed ings 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
         at least a majority or more in principal amount of the Outstanding
         Securities of that series in the case of any Event of Default described
         in clause (1), (2), (3), (4), (7) or (8) of Section 501, or, in the
         case of any Event of Default described in clause (5) or (6) of Section
         501, by the Holders of a majority or more in principal amount of all
         Outstanding Securities;

it being understood and intended that no one or more of such Holders shall have
any right in any manner whatever by virtue of, or by availing of, any provision
of this Indenture to affect, disturb or prejudice the rights of any other
Holders of Securities of the same series, in the case of any Event of Default
described in clause (1), (2), (3), (4), (7) or (8) of Section 501, or of Holders
of all Securities in the case of any Event of Default described in clause (5) or
(6) of Section 501, or to obtain or to seek to obtain priority or preference

Default described in clause (1), (2), (3), (4), (7) or (8) of Section 501, or of
Holders of all Securities in the case of any Event of Default described in

                  Notwithstanding any other provision in this Indenture, the
Holder of any Security shall have the right, which is absolute and
unconditional, to receive payment, as provided herein (including, if applicable,
Article Fourteen) and in such Security, of the principal of (and premium, if
any, on) and (subject to Section 307) interest on, such Security or payment of
such coupon on the respective Stated Maturities expressed in such Security or
coupon (or, in the case of redemption, on the Redemption Date) and to institute
suit for the enforcement of any such payment, and such rights shall not be
impaired without the consent of such Holder.

                  Section 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, subject to any
determination in such proceeding, the Company, the Trustee and the Holders of
Securities and coupons shall be restored severally and respectively to their
former positions hereunder and thereafter all rights and remedies of the Trustee
and the Holders shall continue as though no such proceeding had been instituted.

last paragraph of Section 306, no right or remedy herein conferred upon or
reserved to the Trustee or to the Holders of Securities or coupons is intended
to be exclusive of any other right or remedy, and every right and remedy shall,
to the extent permitted by law, be cumulative and in addition to every other
right and remedy given hereunder or now or hereafter existing at law or in

                  No delay or omission of the Trustee or of any Holder of any
Security or coupon to exercise any right or remedy accruing upon any Event of

Event of Default or an acquiescence therein. Every right and remedy given by
this Article or by law to the Trustee or to the Holders may be exercised from
time to time, and as often as may be deemed expedient, by the Trustee or by the
Holders, as the case may be.

                  With respect to the Securities of any series, the Holders of
not less than a majority in principal amount of the Outstanding Securities of

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

                  (3) the Trustee need not take any action which might involve
         it in personal liability or be unjustly prejudicial to the Holders of
         Securities of such series not consent ing.

                  Section 5.13      WAIVER OF PAST DEFAULTS.

                  Subject to Section 502, the Holders of not less than a
majority in principal amount of the Outstanding Securities of any series may on
behalf of the Holders of all the Securities of such series waive any past
default described in clause (1), (2), (3), (4), (7) or (8) of Section 501 (or,
in the case of a default described in clause (5) or (6) of Section 501, the
Holders of not less than a majority in principal amount of all Outstanding
Securities may waive any such past default), and its consequences, except a
default

                  (1) in respect of the payment of the principal of (or premium,
         if any, on) or interest on any Security or any related coupon, or

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

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

                  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

with respect to the Securities of any series, the Trustee shall transmit in the
manner and to the extent provided in TIA Section 313(c), notice of such default

waived; PROVIDED, HOWEVER, that, except in the case of a Default in the payment
of the principal of (or premium, if any, on) or interest on any Security of such
series or in the payment of any sinking fund installment with respect to
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 Securities of such series and any related coupons; and PROVIDED
FURTHER that in the case of any Default of the character specified in Section
501(4) with respect to Securities of such series, no such notice to Holders

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

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

<Page>

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

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

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

         statement, instrument, opinion, report, notice, request, direction,
         consent, order, bond, debenture, note, other evidence of indebtedness
         or other paper or document, but the Trustee, in its discretion, may
         make such further inquiry or investigation into such facts or matters
         as it may see fit, and, if the Trustee shall determine to make such
         further inquiry or investigation, it shall be entitled to examine the
         books, records and premises of the Company, personally or by agent or
         attorney;

                  (7) the Trustee may execute any of the trusts or powers

         through agents or attorneys and the Trustee shall not be responsible
         for any misconduct or negligence on the part of any agent or attorney
         appointed with due care by it hereunder; and

                  (8) the Trustee shall not be liable for any action taken,
         suffered or omitted by it in good faith and believed by it to be
         authorized or within the discretion or rights or powers conferred upon
         it by this Indenture.

                  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.

                  Section 6.3       TRUSTEE NOT RESPONSIBLE FOR RECITALS OR
                                    ISSUANCE OF SECURITIES.

                  The recitals contained herein and in the Securities, except
for the Trustee's certificates of authentication, and in any coupons shall be
taken as the statements of the Company, and neither the Trustee nor any
Authenticating Agent assumes any responsibility for their correctness. The
Trustee makes no representations as to the validity or sufficiency of this
Indenture or of the Securities or coupons, except that the Trustee represents
that it is duly authorized to execute and deliver this Indenture, authenticate

                  Section 6.4       MAY HOLD SECURITIES.

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

                  Section 6.5       MONEY HELD IN TRUST.

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

                  Section 6.6       COMPENSATION AND REIMBURSEMENT.

                  The Company agrees:

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

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

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

                  The obligations of the Company under this Section to
compensate the Trustee, to pay or reimburse the Trustee for expenses,
disbursements and advances and to indemnify and hold harmless the Trustee shall
constitute additional indebtedness hereunder and shall survive the satisfaction
and discharge of this Indenture. As security for the performance of such
obligations of the Company, the Trustee shall have a claim prior to the
Securities upon all property and funds held or collected by the Trustee as such,
except funds held in trust for the payment of principal of (and premium, if any,
on) or interest on particular Securities or any coupons.

                  Section 6.7       CORPORATE TRUSTEE REQUIRED; ELIGIBILITY;
                                    CONFLICTING INTEREST.

                  There shall at all times be a Trustee hereunder which shall be
eligible to act as Trustee under TIA Section 310(a)(1). Each successor Trustee
shall have a combined capital and surplus of at


                                       49
<Page>

least $50,000,000. If such corporation publishes reports of condition at least
annually, pursuant to law or to the requirements of federal, state, territorial
or District of Columbia supervising or examining authority, then for the
purposes of this Section, the combined capital and surplus of such corporation
shall be deemed to be its combined capital and surplus as set forth in its most
recent report of condition so published. If at any time the Trustee shall cease
to be eligible in accordance with the provisions of this Section, it shall
resign immediately in the manner and with the effect hereinafter specified in
this Article.

                  Section 6.8       RESIGNATION AND REMOVAL; APPOINTMENT OF
                                    SUCCESSOR.

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

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

                  (c) The Trustee may be removed at any time with respect to the
         Securities of any series by Act of the Holders of not less than a
         majority in principal amount of the Outstanding Securities of such
         series, delivered to the Trustee and to the Company.

                  (d) If at any time:

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

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

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

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

                  (e) If the Trustee shall resign, be removed or become
         incapable of acting, or if a vacancy shall occur in the office of
         Trustee for any cause, with respect to the Securities of one or


                                       50
<Page>

         more series, the Company, by a Board Resolution, shall promptly appoint
         a successor Trustee or Trustees with respect to the Securities of that
         or those series (it being understood that any such successor Trustee
         may be appointed with respect to the Securities of one or more or all
         of such series and that at any time there shall be only one Trustee
         with respect to the Securities of any particular series). If, within
         one year after such resignation, removal or incapability, or the
         occurrence of such vacancy, a successor Trustee with respect to the
         Securities of any series shall be appointed by Act of the Holders of a
         majority in principal amount of the Outstanding Securi ties 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
         Securities of such series and to that extent supersede the successor
         Trustee appointed by the Company. If no successor Trustee with respect
         to the Securities of any series shall have been so appointed by the
         Company or the Holders and accepted appointment in the manner
         hereinafter provided, any Holder who has been a bona fide Holder of a
         Security of such series for at least six months may, on behalf of
         himself and all others similarly situated, petition any court of
         competent jurisdiction for the appointment of a successor Trustee with
         respect to the Securities of such series.

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

                  Section 6.9       ACCEPTANCE OF APPOINTMENT BY SUCCESSOR.

                  (a) In case of the appointment hereunder of a successor
         Trustee with respect to all Securities, every such successor Trustee so
         appointed shall execute, acknowledge and deliver to the Company and to
         the retiring Trustee an instrument accepting such appointment, and
         thereupon the resignation or removal of the retiring Trustee shall
         become effective and such successor Trustee, without any further act,
         deed or conveyance, shall become vested with all the rights, powers,
         trusts and duties of the retiring Trustee; but, on the request of the
         Company or the successor Trustee, such retiring Trustee shall, upon
         payment of its charges, execute and deliver an instrument transferring
         to such successor Trustee all the rights, powers and trusts of the
         retiring Trustee and shall duly assign, transfer and deliver to such
         successor Trustee all property and money held by such retiring Trustee
         hereunder.

                  (b) In case of the appointment hereunder of a successor
         Trustee with respect to the Securities of one or more (but not all)
         series, the Company, the retiring Trustee and each successor Trustee
         with respect to the Securities of one or more series shall execute and
         deliver an indenture supplemental hereto wherein each successor Trustee
         shall accept such appointment and which (1) shall contain such
         provisions as shall be necessary or desirable to transfer and confirm
         to, and to vest in, each successor Trustee all the rights, powers,
         trusts and duties of the retiring Trustee with respect to the
         Securities of that or those series to which the appointment of such
         successor Trustee relates, (2) if the retiring Trustee is not retiring
         with respect to all Securities, shall contain such provisions as shall
         be deemed necessary or desirable to confirm that all the rights,
         powers, trusts and duties of the retiring Trustee with respect to the
         Securities of that or those series as to which the retiring Trustee is
         not retiring shall continue to be vested in the


                                       51
<Page>

         retiring Trustee, and (3) shall add to or change any of the provisions
         of this Indenture as shall be necessary to provide for or facilitate
         the administration of the trusts hereunder by more than one Trustee, it
         being understood that nothing herein or in such supplemental indenture
         shall constitute such Trustees co-trustees of the same trust and that
         each such Trustee shall be trustee of a trust or trusts hereunder
         separate and apart from any trust or trusts hereunder administered by
         any other such Trustee; and upon the execution and delivery of such
         supplemental indenture to resignation or removal of the retiring
         Trustee shall become effective to the extent provided therein and each
         such successor Trustee, without any further act, deed or conveyance,
         shall become vested with all the rights, powers, trusts and duties of
         the retiring Trustee with respect to the Securities of that or those
         series to which the appointment of such successor Trustee relates; but,
         on request of the Company or any successor Trustee, such retiring
         Trustee shall duly assign, transfer and deliver to such successor
         Trustee all property and money held by such retiring Trustee hereunder
         with respect to the Securities of that or those series to which the
         appointment of such successor Trustee relates. Whenever there is a
         successor Trustee with respect to one or more (but less than all)
         series of securities issued pursuant to this Indenture, the terms
         "Indenture" and "Securities" shall have the meanings specified in the
         provisos to the respective definitions of those terms in Section 101
         which contemplate such situation.

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

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

                  Section 6.10      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 the corporate
trust business of the Trustee, shall be the successor of the Trustee hereunder,
provided such corporation shall be otherwise qualified and eligible under this
Article, without the execution or filing of any paper or any further act on the
part of any of the parties hereto. In case any Securities shall have been
authenticated, but not delivered, by the Trustee then in office, any successor
by merger, conversion or consolidation to such authenticating Trustee may adopt
such authentication and deliver the Securities so authenticated with the same
effect as if such successor Trustee had itself authenticated such Securities;
and in case at that time any of the Securities shall not have been
authenticated, any successor Trustee may authenticate such Securities either in
the name of any predecessor hereunder or in the name of the successor Trustee;
and in all such cases such certificates shall have the full force which it is
anywhere in the Securities or in this Indenture provided that the certificate of
the Trustee shall have; PROVIDED, HOWEVER, that the right to adopt the
certificate of authentication of any predecessor Trustee or to authenticate
Securities in the name of any predecessor Trustee shall apply only to its
successor or successors by merger, conversion or consolidation.

                  Section 6.11      APPOINTMENT OF AUTHENTICATING AGENT.

                  At any time when any of the Securities remain Outstanding, the
Trustee may appoint an Authenticating Agent or Agents with respect to one or
more series of Securities which shall be authorized to act on behalf of the
Trustee to authenticate Securities of such series and the Trustee shall give
written notice of such appointment to all Holders of Securities of the series
with respect to which such Authenti cating Agent will serve, in the manner
provided for in Section 106. Securities so authenticated shall be entitled to
the benefits of this Indenture and shall be valid and obligatory for all
purposes as if authenti cated by the Trustee hereunder. Any such appointment
shall be evidenced by an instrument in writing signed by a Responsible Officer
of the Trustee, and a copy of such instrument shall be promptly furnished to the
Company. Wherever reference is made in this Indenture to the authentication and
delivery of Securities by the Trustee or the Trustee's certificate of
authentication, such reference shall be deemed to include authentication and
delivery on behalf of the Trustee by an Authenticating Agent and a certificate
of authentication executed on behalf of the Trustee by an Authenticating Agent.
Each Authenticating Agent shall be acceptable to the Company and shall at all
times be a corporation organized and doing business under the laws of the United
States of America, any state thereof or the District of Columbia, authorized
under such laws to act as Authenticating Agent, having a combined capital and
surplus of not less than $50,000,000 and subject to supervision or examination

         executed and delivered to the Trustee, in form satisfactory to the

                  Section 8.2       SUCCESSOR PERSON SUBSTITUTED.

                  Upon any consolidation by the Company with or merger by the
Company into any other corporation or any conveyance, transfer or lease of the
properties and assets of the Company substantially as an entirety to any Person
in accordance with Section 801, the successor Person formed by such
consolidation or into which the Company is merged or to which such conveyance,
transfer or lease is made shall succeed to, and be substituted for, and may
exercise every right and power of, the Company under this Indenture with the
same effect as if such successor Person had been named as the Company herein,
and in the event of any such conveyance or transfer, the Company (which term
shall for this purpose mean the Person named as the "Company" in the first
paragraph of this Indenture or any successor Person which shall theretofore
become such in the manner described in Section 801), except in the case of a
lease, shall be discharged of all obligations and covenants under this Indenture
and the Securities and the coupons and may be dissolved and liquidated.

                  If, upon any such consolidation of the Company with or merger
of the Company into any other corporation, or upon any conveyance, lease or
transfer of the property of the Company as an entirety or substantially as an
entirety to any other Person, any Principal Property of the Company or of any
Subsidiary, would thereupon become subject to any Lien, then unless such Lien
could be created under the Indenture without equally and ratably securing the
Securities, the Company, prior to or simulta neously with such consolidation,
merger, conveyance, lease or transfer, will, as to such Principal Property,
secure the Securities Outstanding hereunder (together with, if the Company shall
so determine, any other Debt of the Company now existing or hereafter created
which is not subordinate to the Securities) equally and ratably with (or prior
to) the Debt which upon such consolidation, merger, conveyance, lease or
transfer is to become secured as to such Principal Property by such Lien, or
will cause such Securities to be so secured; PROVIDED that, for the purpose of
providing such equal and ratable security, the principal amount of Original
Issue Discount Securities and Indexed Securities shall mean that amount which
would at the time of making such effective provision be due and payable pursuant
to Section 502 and the terms of such Original Issue Discount Securities and
Indexed Securities upon a declaration of acceleration of the Maturity thereof,
and the extent of such equal and ratable security shall


                                       56

be adjusted, to the extent permitted by law, as and when said amount changes
over time pursuant to the terms of such Original Issue Discount Securities and
Indexed Securities.

otherwise); (B) subject to any laws or regulations applicable thereto, in a
Place of Payment for that series which is located outside the United States, an
office or agency where Securities of that series and related coupons may be
presented and surrendered for payment; PROVIDED, HOWEVER, that, if the
Securities of that series are listed on any stock exchange located outside the
United States and such stock exchange shall so require, the Company will
maintain a Paying Agent for the Securities of that series in any required city
located


                                       60
<Page>

outside the United States so long as the Securities of that series are listed on
such exchange, and (C) subject to any laws or regulations applicable thereto, in
a Place of Payment for that series located outside the United States an office
or agency where any Registered Securities of that series may be surrendered for
registration of transfer, where Securities of that series may be surrendered for
exchange and where notices and demands to or upon the Company in respect of the
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. If at
any time the Company shall fail to maintain any such required office or agency
or shall fail to furnish the Trustee with the address thereof, such presenta
tions, surrenders, notices and demands may be made or served at the Corporate
Trust Office of the Trustee, except that Bearer Securities of any series and the
related coupons may be presented and surrendered for payment at the offices
specified in the Security, in London, and the Company hereby appoints the same
as its agents to receive such respective presentations, surrenders, notices and
demands.

                  Unless otherwise specified with respect to any Securities
pursuant to Section 301, no payment of principal, premium or interest on Bearer
Securities shall be made at any office or agency of the Company in the United
States or by check mailed to any address in the United States or by transfer to
an account maintained with a bank located in the United States; PROVIDED,
HOWEVER, that, if the Securities of a series are payable in Dollars, payment of
principal of (and premium, if any, on) and interest on any Bearer Security shall
be made at the office of the Company's Paying Agent in The City of New York, if
(but only if) payment in Dollars of the full amount of such principal, premium
or interest, as the case may be, at all offices or agencies outside the United
States maintained for 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 one or more
other offices or agencies where the Securities of one or more series may be
presented or surrendered for any or all such purposes and may from time to time
rescind any such designation; PROVIDED, HOWEVER, that no such designation or
rescission shall in any manner relieve the Company of its obligation to maintain
an office or agency in accordance with the requirements set forth above for
Securities of any series for such purposes. The Company will give prompt written
notice to the Trustee of any such designation or rescission and of any change in
the location of any such other office or agency. Unless otherwise specified with
respect to any Securities as contemplated by Section 301 with respect to a
series of Securities, the Company hereby designates as a Place of Payment for
each series of Securities the office or agency of the Trustee in the Borough of
Manhattan, The City of New York, and initially appoints the Trustee, as Paying
Agent in such city as its agent to receive all such presentations, surrenders,
notices and demands.

                  Unless otherwise specified with respect to any Securities
pursuant to Section 301, if and so long as the Securities of any series (i) are
denominated in a Currency other than Dollars or (ii) may be payable in a
Currency other than Dollars, or so long as it is required under any other
provision of the Indenture, then the Company will maintain with respect to each
such series of Securities, or as so required, at least one Exchange Rate Agent.

                  Section 10.3      MONEY FOR SECURITIES PAYMENTS TO BE HELD
                                    IN TRUST.

                  If the Company shall at any time act as its own Paying Agent
with respect to any series of Securities and any related coupons, it will, on or
before each due date of the principal of (and premium, if any, on) or interest
on any of the Securities of that series, segregate and hold in trust for the
benefit of the Persons entitled thereto a sum in the Currency in which the
Securities of such series are payable (except as otherwise specified pursuant to
Section 301 for the Securities of such series and except, if applicable, as
provided in Sections 312(b), 312(d) and 312(e)) 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 for
any series of Securities and any related coupons, it will, prior to or on each
due date of the principal of (and premium, if any, on) or interest on any
Securities of that series, deposit with a Paying Agent a sum (in the Currency
described in the preceding paragraph) sufficient to pay the principal (and
premium, if any) or interest so becoming due, such sum to be held in trust for
the benefit of the Persons entitled to such principal, premium or interest, and
(unless such Paying Agent is the Trustee) the Company will promptly notify the
Trustee of its action or failure so to act.

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

                  (1) hold all sums held by it for the payment of the principal
         of (and premium, if any, on) and interest on Securities of such series
         in trust for the benefit of the Persons entitled thereto until such
         sums shall be paid to such Persons or otherwise disposed of as herein
         provided;

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

                  (3) at any time during the continuance of any such default,
         upon the written request of the Trustee, forthwith pay to the Trustee
         all sums so held in trust by such Paying Agent.

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

                  Except as provided in the Securities of any series, any money
deposited with the Trustee or any Paying Agent, or then held by the Company, in
trust for the payment of the principal of (and premium, if any, on) or interest
on any Security of any series, or any coupon appertaining thereto, and remaining
unclaimed for two years after such principal (and premium, if any) or interest
has become due


                                       62
<Page>

and payable shall be paid to the Company on Company Request, or (if then held by
the Company) shall be discharged from such trust; and the Holder of such
Security or coupon shall thereafter, as an unsecured general creditor, look only
to the Company for payment thereof, and all liability of the Trustee or such
Paying Agent with respect to such trust money, and all liability of the Company
as trustee thereof, shall thereupon cease; PROVIDED, HOWEVER, that the Trustee
or such Paying Agent, before being required to make any such repayment, may at
the expense of the Company cause to be published once, in an Authorized
Newspaper, notice that such money remains unclaimed and that, after a date
specified therein, which shall not be less than 30 days from the date of such
publication, any unclaimed balance of such money then remaining will be repaid
to the Company.

                  Section 10.4      STATEMENT AS TO COMPLIANCE.

                  The Company will deliver to the Trustee, within 120 days after
the end of each fiscal year, a brief certificate from the principal executive
officer, principal financial officer or principal accounting officer as to his
or her knowledge of the Company's compliance with all conditions and covenants
under this Indenture. For purposes of this Section 1004, such compliance shall
be determined without regard to any period of grace or requirement of notice
under this Indenture.

                  Section 10.5      ADDITIONAL AMOUNTS.

                  If any Securities of a series provide for the payment of
additional amounts to any Holder who is not a United States person in respect of
any tax, assessment or governmental charge ("Additional Amounts"), the Company
will pay to the Holder of any Security of such series or any coupon appertain
ing thereto such Additional Amounts as may be specified as contemplated by
Section 301. Whenever in this Indenture there is mentioned, in any context, the
payment of the principal (or premium, if any, on) or interest on, or in respect
of, any Security of a series or payment of any related coupon or the net
proceeds received on the sale or exchange of any Security of a series, such
mention shall be deemed to include mention of the payment of Additional Amounts
provided for by the terms of such series established pursuant to Section 301 to
the extent that, in such context, Additional Amounts are, were or would be
payable in respect thereof pursuant to such terms and express mention of the
payment of Additional Amounts (if applicable) in any provisions hereof shall not
be construed as excluding Additional Amounts in those provisions hereof where
such express mention is not made.

                  Except as otherwise specified as contemplated by Section 301,
if the Securities of a series provide for the payment of Additional Amounts, at
least 10 days prior to the first Interest Payment Date with respect to that
series of Securities (or if the Securities of that series will not bear interest
prior to Maturity, the first day on which a payment of principal (and premium,
if any) is made), and at least 10 days prior to each date of payment of
principal (and premium, if any) or interest if there has been any change with
respect to the matters set forth in the below-mentioned Officers' Certificate,
the Company will furnish the Trustee and the Company's principal Paying Agent or
Paying Agents, if other than the Trustee, with an Officers' Certificate
instructing the Trustee and such Paying Agent or Paying Agents whether such
payment of principal of (and premium, if any, on) or interest on the Securities
of that series shall be made to Holders of Securities of that series or any
related coupons who are not United States persons without withholding for or on
account of any tax, assessment or other governmental charge described in the
Securities of the series. If any such withholding shall be required, then such
Officers' Certificate shall specify by country the amount, if any, required to
be withheld on such payments to such Holders of Securities of that series or
related coupons and the Company will pay to the Trustee or such


                                       63
<Page>

Paying Agent the Additional Amounts required by the terms of such Securities. In
the event that the Trustee or any Paying Agent, as the case may be, shall not so
receive the above-mentioned certificate, then the Trustee or such Paying Agent
shall be entitled to (i) assume that no such withholding or deduction is
required with respect to any payment of principal (and premium, if any) or
interest with respect to any Securities of a series or related coupons until it
shall have received a certificate advising otherwise and (ii) to make all
payments of principal (and premium, if any) and interest with respect to the
Securities of a series or related coupons without withholding or deductions
until otherwise advised. The Company covenants to indemnify the Trustee and any
Paying Agent for, and to hold them harmless against, any loss, liability or
expense reasonably incurred without negligence or bad faith on their part
arising out of or in connection with actions taken or omitted by any of them in
reliance on any Officers' Certificate furnished pursuant to this Section.

                  Section 10.6      PAYMENT OF TAXES AND OTHER CLAIMS.

                  The Company will pay or discharge or cause to be paid or
discharged, before the same shall become delinquent, (1) all material taxes,
assessments and governmental charges levied or imposed upon the Company or any
Subsidiary or upon the income, profits or property of the Company or any
Subsidiary, and (2) all material lawful claims for labor, materials and supplies
which, if unpaid, might by law become a Lien upon any Principal Property of the
Company or any Subsidiary; PROVIDED, HOWEVER, that the Company shall not be
required to pay or discharge or cause to be paid or discharged any such tax,
assessment, charge or claim whose amount, applicability or validity is being
contested in good faith by appropriate proceedings.

                  Section 10.7      CORPORATE EXISTENCE.

                  Subject to Article Eight, the Company will do or cause to be
done all things necessary to preserve and keep in full force and effect its
corporate existence and the rights (charter and statutory) and franchises of the
Company and any Subsidiary; 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 and its Subsidiaries as a whole and PROVIDED FURTHER
that the foregoing does not prohibit any mergers or consolidations between
Subsidiaries or between the Company and one or more Subsidiaries so long as any
such merger or consolidation complies with Article Eight.

                  Section 10.8      WAIVER OF CERTAIN COVENANTS.

                  The Company may, with respect to any series of Securities,
omit in any particular instance to comply with any term, provision or condition
which affects such series set forth in Section 803 or Sections 1006 to 1007,
inclusive, if before the time for such compliance the Holders of at least a
majority in principal amount of all Outstanding Securities of any series, by Act
of such Holders, waive such compliance in such instance with such term,
provision or condition, but no such waiver shall extend to or affect such term,
provision or condition except to the extent so expressly waived, and, until such
waiver shall become effective, the obligations of the Company and the duties of
the Trustee in respect of any such term, provision or condition shall remain in
full force and effect.

                            REDEMPTION OF SECURITIES

                  Section 11.1      APPLICABILITY OF ARTICLE.

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

                  Section 11.2      ELECTION TO REDEEM; NOTICE TO TRUSTEE.

                  The election of the Company to redeem any Securities shall be
evidenced by or pursuant to a Board Resolution. In case of any redemption at the
election of the Company, the Company shall, at least 60 days prior to the
Redemption Date fixed by the Company (unless a shorter notice shall be
satisfactory to the Trustee), notify the Trustee of such Redemption Date and of
the principal amount of Securities of such series to be redeemed and shall
deliver to the Trustee such documentation and records as shall enable the
Trustee to select the Securities to be redeemed pursuant to Section 1103. In the
case of any redemption of Securities prior to the expiration of any restriction
on such redemption provided in the terms of such Securities or elsewhere in this
Indenture, the Company shall furnish the Trustee with an Officers' Certificate
evidencing compliance with such restriction.

                  Section 11.3      SELECTION BY TRUSTEE OF SECURITIES TO BE
                                    REDEEMED.

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

                  The Trustee shall promptly notify the Company in writing of
the Securities selected for redemption and, in the case of any Securities
selected for partial redemption, the principal amount thereof to be redeemed.

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

                  Section 11.4      NOTICE OF REDEMPTION.

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


                                       65
<Page>

                  All notices of redemption shall state:

                           (1) the Redemption Date,

                           (2) the Redemption Price,

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

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

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

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

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

                           (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 such
                  Redemption Date pursuant to Section 305 or otherwise, the last
                  date, as determined by the Company, on which such exchanges
                  may be made.

                  Notice of redemption of Securities to be redeemed at the
election of the Company shall be given by the Company or, at the Company's
request, by the Trustee in the name and at the expense of the Company.

                  Section 11.5      DEPOSIT OF REDEMPTION PRICE.

                  Prior to any Redemption Date, the Company shall deposit with
the Trustee or with a Paying Agent (or, if the Company is acting as its own
Paying Agent, segregate and hold in trust as provided in Section 1003) an amount
of money in the Currency in which the Securities of such series are payable
(except as otherwise specified pursuant to Section 301 for the Securities of
such series and except, if applicable, as provided in Sections 312(b), 312(d)
and 312(e)) sufficient to pay the Redemption Price of, and accrued interest on,
all the Securities which are to be redeemed on that date.

                  Section 11.6      SECURITIES PAYABLE ON REDEMPTION DATE.

                  Notice of redemption having been given as aforesaid, the
Securities so to be redeemed shall, on the Redemption Date, become due and
payable at the Redemption Price therein specified in the Currency in which the
Securities of such series are payable (except as otherwise specified pursuant to
Section 301 for the Securities of such series and except, if applicable, as
provided in Sections 312(b), 312(d) and 312(e)) (together with accrued interest,
if any, to the Redemption Date), and from and after such date (unless the
Company shall default in the payment of the Redemption Price and accrued
interest) such Securities shall, if the same were interest-bearing, cease to
bear interest and the coupons for such interest appertaining to any Bearer
Securities so to be redeemed, except to the extent provided below, shall be
void. Upon surrender of any such Security for redemption in accordance with said
notice, together with all coupons, if any, appertaining thereto maturing after
the Redemption Date, such Security shall be paid by the Company at the
Redemption Price, together with accrued interest, if any, to the Redemption
Date; PROVIDED, HOWEVER, that installments of interest on Bearer Securities
whose Stated Maturity is on or prior to the Redemption Date shall be payable
only at an office or agency located outside the United States (except as
otherwise provided in Section 1002) and, unless otherwise specified as
contemplated by Section 301, only upon presentation and surrender of coupons for
such interest, and PROVIDED FURTHER that installments of interest on Registered
Securities whose Stated Maturity is on or prior to the Redemption Date shall be
payable to the Holders of such Securities, or one or more Predecessor
Securities, registered as such at the close of business on the relevant Record
Dates according to their terms and the provisions of Section 307.

                  If any Bearer Security surrendered for redemption shall not be
accompanied by all appurtenant coupons maturing after the Redemption Date, such
Security may be paid after deducting from the Redemption Price an amount equal
to the face amount of all such missing coupons, or the surrender of such missing
coupon or coupons may be waived by the Company and the Trustee if there be
furnished to them such security or indemnity as they may require to save each of
them and any Paying Agent harmless. If thereafter the Holder of such Security
shall surrender to the Trustee or any Paying Agent any such missing coupon in
respect of which a deduction shall have been made from the Redemption Price,
such Holder shall be entitled to receive the amount so deducted; PROVIDED,
HOWEVER, that interest represented by coupons shall be payable only at an office
or agency located outside the United States (except as otherwise provided in
Section 1002) and, unless otherwise specified as contemplated by Section 301,
only upon presentation and surrender of those coupons.

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

                  Section 11.7      SECURITIES REDEEMED IN PART.

                  Any Security which is to be redeemed only in part (pursuant to
the provisions of this Article or of Article Twelve) shall be surrendered at a
Place of Payment therefor (with, if the Company or the Trustee so requires, due
endorsement by, or a written instrument of transfer in form satisfactory to the
Company and the Trustee duly executed by, the Holder thereof or such Holder's
attorney duly authorized in writing), and the Company shall execute, and the
Trustee shall authenticate and deliver to the Holder


                                       67
<Page>

of such Security without service charge, a new Security or Securities of the
same series, of any authorized denomination as requested by such Holder, in
aggregate principal amount equal to and in exchange for the unredeemed portion
of the principal of the Security so surrendered.

                                   ARTICLE XII

                                  SINKING FUNDS

                  Section 12.1      APPLICABILITY OF ARTICLE.

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

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

                  Section 12.2      SATISFACTION OF SINKING FUND PAYMENTS WITH
                                    SECURITIES.

                  Subject to Section 1203, in lieu of making all or any part of
any mandatory sinking fund payment with respect to any Securities of a series in
cash, the Company may at its option (1) deliver to the Trustee Outstanding
Securities of a series (other than any previously called for redemption)
theretofore purchased or otherwise acquired by the Company together in the case
of any Bearer Securities of such series with all unmatured coupons appertaining
thereto, and/or (2) receive credit for the principal amount of Securities of
such series which have been previously delivered to the Trustee by the Company
or for Securities of such series which have been redeemed either at the election
of the Company pursuant to the terms of such Securities or through the
application of permitted optional sinking fund payments pursuant to the terms of
such Securities, in each case in satisfaction of all or any part of any
mandatory sinking fund payment with respect to the Securities of the same series
required to be made pursuant to the terms of such Securities as provided for by
the terms of such series; PROVIDED, HOWEVER, that such Securities have not been
previously so credited. Such Securities shall be received and credited for such
purpose by the Trustee at the Redemption Price specified in such Securities for
redemption through operation of the sinking fund and the amount of such
mandatory sinking fund payment shall be reduced accordingly.

                  Section 12.3      REDEMPTION OF SECURITIES FOR SINKING FUND.

                  Not less than 60 days prior to each sinking fund payment date
for any series of Securities, the Company will deliver to the Trustee an
Officers' Certificate specifying the amount of the next ensuing sinking fund
payment for that series pursuant to the terms of that series, the portion
thereof, if any, which is to be satisfied by payment of cash in the Currency in
which the Securities of such series are payable (except as otherwise specified
pursuant to Section 301 for the Securities of such series and except, if


                                       68
<Page>

applicable, as provided in Sections 312(b), 312(d) and 312(e)) and the portion
thereof, if any, which is to be satisfied by delivering or crediting Securities
of that series pursuant to Section 1202 (which Securities will, if not
previously delivered, accompany such certificate) and whether the Company
intends to exercise its right to make a permitted optional sinking fund payment
with respect to such series. Such certificate shall be irrevocable and upon its
delivery the Company shall be obligated to make the cash payment or payments
therein referred to, if any, on or before the next succeeding sinking fund
payment date. In the case of the failure of the Company to deliver such
certificate, the sinking fund payment due on the next succeeding sinking fund
payment date for that series shall be paid entirely in cash and shall be
sufficient to redeem the principal amount of such Securities subject to a
mandatory sinking fund payment without the option to deliver or credit
Securities as provided in Section 1202 and without the right to make any
optional sinking fund payment, if any, with respect to such series.

                  Not more than 60 days before each such sinking fund payment
date the Trustee shall select the Securities to be redeemed upon such sinking
fund payment date in the manner specified in Section 1103 and cause notice of
the redemption thereof to be given in the name of and at the expense of the
Company in the manner provided in Section 1104. Such notice having been duly
given, the redemption of such Securities shall be made upon the terms and in the
manner stated in Sections 1106 and 1107.

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

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

                         REPAYMENT AT OPTION OF HOLDERS

                  Section 13.1      APPLICABILITY OF ARTICLE.

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

                  Section 13.2      REPAYMENT OF SECURITIES.

                  Securities of any series subject to repayment in whole or in
part at the option of the Holders thereof will, unless otherwise provided in the
terms of such Securities, be repaid at a price equal to the principal amount
thereof, together with interest, if any, thereon accrued to the Repayment Date
specified in or pursuant to the terms of such Securities. The Company covenants
that on or before the Repayment Date it will deposit with the Trustee or with a
Paying Agent (or, if the Company is acting as its own Paying Agent, segregate
and hold in trust as provided in Section 1003) an amount of money in the
Currency in which the Securities of such series are payable (except as otherwise
specified pursuant to Section 301 for the Securities of such series and except,
if applicable, as provided in Sections 312(b), 312(d) and 312(e)) sufficient to
pay the principal (or, if so provided by the terms of the Securities of any
series, a percentage of the principal) of, and (except if the Repayment Date
shall be an Interest Payment Date) accrued interest on, all the Securities or
portions thereof, as the case may be, to be repaid on such date.

                  Section 13.3      EXERCISE OF OPTION.

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

                  Section 13.4      WHEN SECURITIES PRESENTED FOR REPAYMENT
                                    BECOME DUE AND PAYABLE.

                  If Securities of any series providing for repayment at the
option of the Holders thereof shall have been surrendered as provided in this
Article and as provided by or pursuant to the terms of such Securities, such
Securities or the portions thereof, as the case may be, to be repaid shall
become due and payable and shall be paid by the Company on the Repayment Date
therein specified, and on and after such Repayment Date (unless the Company
shall default in the payment of such Securities on such Repayment Date) such
Securities shall, if the same were interest-bearing, cease to bear interest and
the coupons for such interest appertaining to any Bearer Securities so to be
repaid, except to the extent provided below, shall be void. Upon surrender of
any such Security for repayment in accordance with such provisions, together
with all coupons, if any, appertaining thereto maturing after the Repayment
Date, the principal amount of such Security so to be repaid shall be paid by the
Company, together with


                                       70
<Page>

accrued interest, if any, to the Repayment Date; PROVIDED, HOWEVER, that coupons
whose Stated Maturity is on or prior to the Repayment Date shall be payable only
at an office or agency located outside the United States (except as otherwise
provided in Section 1002) and, unless otherwise specified pursuant to Section
301, only upon presentation and surrender of such coupons, and PROVIDED FURTHER
that, in the case of Registered Securities, installments of interest, if any,
whose Stated Maturity is on or prior to the Repayment Date shall be payable to
the Holders of such Securities, or one or more Predecessor Securities,
registered as such at the close of business on the relevant Record Dates
according to their terms and the provisions of Section 307.

                  If any Bearer Security surrendered for repayment shall not be
accompanied by all appurtenant coupons maturing after the Repayment Date, such
Security may be paid after deducting from the amount payable therefor as
provided in Section 1302 an amount equal to the face amount of all such missing
coupons, or the surrender of such missing coupon or coupons may be waived by the
Company and the Trustee if there be furnished to them such security or indemnity
as they may require to save each of them and any Paying Agent harmless. If
thereafter the Holder of such Security shall surrender to the Trustee or any
Paying Agent any such missing coupon in respect of which a deduction shall have
been made as provided in the preceding sentence, such Holder shall be entitled
to receive the amount so deducted; PROVIDED, HOWEVER, that interest represented
by coupons shall be payable only at an office or agency located outside the
United States (except as otherwise provided in Section 1002) and, unless
otherwise specified as contemplated by Section 301, only upon presentation and
surrender of those coupons.

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

                  Section 13.5      SECURITIES REPAID IN PART.

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

                       DEFEASANCE AND COVENANT DEFEASANCE

                  Section 14.1      COMPANY'S OPTION TO EFFECT DEFEASANCE OR
                                    COVENANT DEFEASANCE.

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

                  Section 14.2      DEFEASANCE AND DISCHARGE.

                  Upon the Company's exercise of the above option applicable to
this Section with respect to any Securities of or within a series, the Company
shall be deemed to have been discharged from its obligations with respect to
such Outstanding Securities and any related coupons on the date the conditions
set forth in Section 1404 are satisfied (hereinafter, "defeasance"). For this
purpose, such defeasance means that the Company shall be deemed to have paid and
discharged the entire indebtedness represented by such Outstanding Securities
and any related coupons, which shall thereafter be deemed to be "Outstanding"
only for the purposes of Section 1405 and the other Sections of this Indenture
referred to in (A) and (B) below, and to have satisfied all its other
obligations under such Securities and any related coupons and this Indenture
insofar as such Securities and any related coupons are concerned (and the
Trustee, at the expense of the Company, shall execute proper instruments
acknowledging the same), except for the following which shall survive until
otherwise terminated or discharged hereunder: (A) the rights of Holders of such
Outstanding Securities and any related coupons (i) to receive, solely from the
trust fund described in Section 1404 and as more fully set forth in such
Section, payments in respect of the principal of (and premium, if any, on) and
interest on such Securities and any related coupons when such payments are due,
and (ii) to receive shares of common stock or other Securities from the Company
upon the conversion of any convertible securities issued hereunder, (B) the
Company's obligations with respect to such Securities under Sections 304, 305,
306, 1002 and 1003 and with respect to the payment of Additional Amounts, if
any, on such Securities as contemplated by Section 1005, (C) the rights, powers,
trusts, duties and immunities of the Trustee hereunder and (D) this Article
Fourteen. Subject to compliance with this Article Fourteen, the Company may
exercise its option under this Section 1402 notwithstanding the prior exercise
of its option under Section 1403 with respect to such Securities and any related
coupons.

                  Section 14.3      COVENANT DEFEASANCE.

                  Upon the Company's exercise of the above option applicable to
this Section with respect to any Securities of or within a series, the Company
shall be released from its obligations under Section 803 and Sections 1006
through 1008, and, if specified pursuant to Section 301, its obligations under
any other covenant, with respect to such Outstanding Securities and any related
coupons on and after the date the conditions set forth in Section 1404 are
satisfied (hereinafter, "covenant defeasance"), and such Securities and any
related coupons shall thereafter be deemed not to be "Outstanding" for the
purposes of any direction, waiver, consent or declaration or Act of Holders (and
the consequences of any thereof) in connection with such covenants, but shall
continue to be deemed "Outstanding" for all other purposes hereunder. For this
purpose, such covenant defeasance means that, with respect to such Outstanding
Securities and any related coupons, the Company may omit to comply with and
shall have no liability in respect of any term, condition or limitation set
forth in any such covenant, whether directly or indirectly, by reason of any
reference elsewhere herein to any such covenant or by reason of reference in any
such covenant to any other provision herein or in any other document and such
omission to comply shall not constitute a Default or an Event of Default under
Section 501(4) or Section 501(8) or otherwise, as the case may be, but, except
as specified above, the remainder of this Indenture and such Securities and any
related coupons shall be unaffected thereby.

                  Section 14.4      CONDITIONS TO DEFEASANCE OR COVENANT
                                    DEFEASANCE.

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

                  (1) The Company shall irrevocably have deposited or caused to
         be deposited with the Trustee (or another trustee satisfying the
         requirements of Section 607 who shall agree to comply with the
         provisions of this Article Fourteen applicable to it) in trust for the
         purpose of making the following payments, specifically pledged as
         security for, and dedicated solely to, the benefit of the Holders of
         such Securities and any related coupons, (A) money in an amount (in
         such Currency in which such Securities and any related coupons are then
         specified as payable at Stated Maturity), or (B) Government Obligations
         applicable to such Securities (determined on the basis of the Currency
         in which such Securities are then specified as payable at Stated
         Maturity) which through the scheduled payment of principal and interest
         in respect thereof in accordance with their terms will provide, not
         later than one day before the due date of any payment of principal
         (including any premium) and interest, if any, under such Securities and
         any related coupons, money in an amount, or (C) a combination thereof,
         sufficient, in the opinion of a nationally recognized firm of
         independent public accountants expressed in a written certification
         thereof delivered to the Trustee, to pay and discharge, and which shall
         be applied by the Trustee (or other qualifying trustee) to pay and
         discharge, (i) the principal of (and premium, if any, on) and interest
         on such Outstanding Securities and any related coupons on the Stated
         Maturity (or Redemption Date, if applicable) of such principal (and pre
         mium, if any) or installment or interest and (ii) any mandatory sinking
         fund payments or analogous payments applicable to such Outstanding
         Securities and any related coupons on the day on which such payments
         are due and payable in accordance with the terms of this Indenture and
         of such Securities and any related coupons; PROVIDED that the Trustee
         shall have been irrevocably instructed to apply such money or the
         proceeds of such Government Obligations to said payments with respect
         to such Securities and any related coupons. Before such a deposit, the
         Company may give to the Trustee, in accordance with Section 1102
         hereof, a notice of its election to redeem all or any portion of such
         Outstanding Securities at a future date in accordance with the terms of
         the Securities of such series and Article Eleven hereof, which notice
         shall be irrevocable. Such irrevocable redemption notice, if given,
         shall be given effect in applying the foregoing.

                  (2) No Default or Event of Default with respect to such
         Securities or any related coupons shall have occurred and be continuing
         on the date of such deposit or, insofar as paragraphs (5) and (6) of
         Section 501 are concerned, at any time during the period ending on the
         91st day after the date of such deposit (it being understood that this
         condition shall not be deemed satisfied until the expiration of such
         period).

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

<Page>

                  (4) In the case of an election under Section 1402, the Company
         shall have delivered to the Trustee an Opinion of Counsel stating that
         (x) the Company has received from, or there has been published by, the
         Internal Revenue Service a ruling, or (y) since the date of execution
         of this Indenture, there has been a change in the applicable federal
         income tax law, in either case to the effect that, and based thereon
         such opinion shall confirm that, the Holders of such Outstanding
         Securities and any related coupons will not recognize income, gain or
         loss for federal income tax purposes as a result of such defeasance and
         will be subject to federal income tax on the same amounts, in the same
         manner and at the same times as would have been the case if such
         defeasance had not occurred.

                  (5) In the case of an election under Section 1403, the Company
         shall have delivered to the Trustee an Opinion of Counsel to the effect
         that the Holders of such Outstanding Securities and any related coupons
         will not recognize income, gain or loss for federal income tax purposes
         as a result of such covenant defeasance and will be subject to federal
         income tax on the same amounts, in the same manner and at the same
         times as would have been the case if such covenant defeasance had not
         occurred.

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

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

                  Section 14.5 DEPOSITED MONEY AND GOVERNMENT OBLIGATIONS TO BE
HELD IN TRUST; OTHER MISCELLANEOUS PROVISIONS.

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

                  Unless otherwise specified with respect to any Security
pursuant to Section 301, if, after a deposit referred to in Section 1404(1) has
been made, (a) the Holder of a Security in respect of which such deposit was
made is entitled to, and does, elect pursuant to Section 312(b) or the terms of
such Security to receive payment in a Currency other than that in which the
deposit pursuant to Section 1404(1) has been made in respect of such Security,
or (b) a Conversion Event occurs as contemplated in Section 312(d) or 312(e) or
by the terms of any Security in respect of which the deposit pursuant to


                                       74
<Page>

Section 1404(1) has been made, the indebtedness represented by such Security and
any related coupons shall be deemed to have been, and will be, fully discharged
and satisfied through the payment of the principal of (premium, if any, on), and
interest, if any, on such Security as they become due out of the proceeds
yielded by converting (from time to time as specified below in the case of any
such election) the amount or other property deposited in respect of such
Security into the Currency in which such Security becomes payable as a result of
such election or Conversion Event based on the applicable Market Exchange Rate
for such Currency in effect on the third Business Day prior to each payment
date, except, with respect to a Conversion Event, for such Currency in effect
(as nearly as feasible) at the time of the Conversion Event.

                  The Company shall pay and indemnify the Trustee against any
tax, fee or other charge imposed on or assessed against the Government
Obligations deposited pursuant to Section 1404 or the principal and interest
received in respect thereof other than any such tax, fee or other charge which
by law is for the account of the Holders of such Outstanding Securities and any
related coupons.

                  Anything in this Article Fourteen to the contrary
notwithstanding, the Trustee shall deliver or pay to the Company from time to
time upon Company Request any money or Government Obligations (or other property
and any proceeds therefrom) held by it as provided in Section 1404 which, in the
opinion of a nationally recognized firm of independent public accountants
expressed in a written certification thereof delivered to the Trustee, are in
excess of the amount thereof which would then be required to be deposited to
effect an equivalent defeasance or covenant defeasance, as applicable, in
accordance with this Article.

                  Section 14.6      REINSTATEMENT.

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

                  Section 15.2      CALL, NOTICE AND PLACE OF MEETINGS.

                  (a) The Trustee may at any time call a meeting of Holders of
         Securities of any series for any purpose specified in Section 1501, to
         be held at such time and at such place in The City of New York or in
         London as the Trustee shall determine. Notice of every meeting of
         Holders of Securities of any series, setting forth the time and the
         place of such meeting and in general terms the action proposed to be
         taken at such meeting, shall be given, in the manner provided for in
         Section 106, not less than 21 nor more than 180 days prior to the date
         fixed for the meeting.

                  (b) In case at any time the Company, pursuant to a Board
         Resolution, or the Holders of at least 10% in principal amount of the
         Outstanding Securities of any series shall have requested the Trustee
         to call a meeting of the Holders of Securities of such series for any
         purpose specified in Section 1501, by written request setting forth in
         reasonable detail the action proposed to be taken at the meeting, and
         the Trustee shall not have made the first publication of the notice of
         such meeting within 21 days after receipt of such request or shall not
         thereafter proceed to cause the meeting to be held as provided herein,
         then the Company or the Holders of Securities of such series in the
         amount above specified, as the case may be, may determine the time and
         the place in The City of New York or in London for such meeting and may
         call such meeting for such purposes by giving notice thereof as
         provided in paragraph (a) of this Section.

                  Section 15.3      PERSONS ENTITLED TO VOTE AT MEETINGS.

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

                  Section 15.4      QUORUM; ACTION.

                  The Persons entitled to vote a majority in principal amount of
the Outstanding Securities of a series shall constitute a quorum for a meeting
of Holders of Securities of such series; PROVIDED, HOWEVER, that, if any action
is to be taken at such meeting with respect to a consent or waiver which this
Indenture expressly provides may be given by the Holders of not less than a
specified percentage in principal amount of the Outstanding Securities of a
series, the Persons entitled to vote such specified percentage in principal
amount of the Outstanding Securities of such series shall constitute a quorum.
In the absence of a quorum within 30 minutes of the time appointed for any such
meeting, the meeting shall, if convened at the request of Holders of Securities
of such series, be dissolved. In any other case the meeting may be adjourned for
a period of not less than 10 days as determined by the chairman of the meeting
prior to the adjournment of such meeting. In the absence of a quorum at any such
adjourned meeting, such adjourned meeting may be further adjourned for a period
of not less than 10 days as determined by the chairman of the meeting prior to
the adjournment of such adjourned meeting. Notice of the reconvening of any
adjourned meeting shall be given as provided in Section 1502(a), except that
such notice need be given only once not less than five days prior to the date on
which the meeting is scheduled to be reconvened. Notice of the reconvening of

<Page>

the percentage, as provided above, of the principal amount of the Outstanding
Securities of such series which shall constitute a quorum.

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

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

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

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

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

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

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

                  (a) Notwithstanding any provisions of this Indenture, the
         Trustee may make such reasonable regulations as it may deem advisable
         for any meeting of Holders of Securities of a series in regard to proof
         of the holding of Securities of such series and of the appointment of
         proxies and in regard to the appointment and duties of inspectors of
         votes, the submission and examination of proxies, certificates and
         other evidence of the right to vote, and such other matters concerning
         the conduct of the meeting as its shall deem appropriate. Except as
         otherwise permitted or required by any such regulations, the holding of
         Securities shall be proved in the manner specified in Section 104 and
         the appointment of any proxy shall be proved in the manner specified in
         Section 104 or by having the signature of the person executing the
         proxy witnessed or


                                       77
<Page>

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

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

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

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

                  Section 15.6      COUNTING VOTES AND RECORDING ACTION OF
                                    MEETINGS.

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

                  This Indenture may be executed in any number of counterparts,
each of which so executed shall be deemed to be an original, but all such
counterparts shall together constitute but one and the same Indenture.

         This is to certify that as of the date hereof, and except as set forth
below, the above-captioned Securities held by you for our account (i) are owned

("United States persons(s)"), (ii) are owned by United States person(s) that are

2.165-12(c)(1)(v) are herein referred to as "financial institutions") purchasing
for their own account or for resale, or (b) United States person(s) who acquired
the Securities through foreign branches of United States financial institutions
and who hold the Securities through such United States financial institutions on
the date hereof (and in either case (a) or (b), each such United States
financial institution hereby agrees, on its own behalf or through its agent,
that you may advise [Name of Issuer] or its agent that such financial
institution will comply with the requirements of Section 165(j)(3)(A), (B) or
(C) of the United States Internal Revenue Code of 1986, as amended, and the

clause (i) or (ii)), this is to further certify that such financial institution
has not acquired the Securities for purposes of resale directly or indirectly to
a United States person or to a person within the United States or its
