                   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 as to such
matters are erroneous.

                   Any certificate or opinion of an officer of the Company or of
counsel may be based, insofar as it relates to accounting matters, upon a
certificate or opinion of or representations by an accountant or

                                       9

firm of accountants in the employ of the Company, unless such officer or
counsel, as the case may be, knows, or in the exercise of reasonable care should
know, that the certificate or opinions or representations as to such accounting
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 may be embodied in and evidenced
by one or more instruments of substantially similar tenor signed by such Holders
in person or by agent duly appointed in writing; and, except as herein otherwise
expressly provided, such action shall become effective when such instrument or
instruments are delivered to the Trustee and, where it is hereby expressly
required, to the Company. Such instrument or instruments (and the action
embodied therein and evidenced thereby) are herein sometimes referred to as the
"Act" of the Holders signing such instrument or instruments. Proof of execution
of any such instrument or of a writing appointing any such agent 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.

                   (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 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 his 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 ownership of Bearer Securities may be proved by the
production of such Bearer Securities or by a certificate executed 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 (i) another such certificate or affidavit
bearing a later date issued in respect of the same Bearer Security is produced,
(ii) such Bearer Security is produced to the Trustee by some other Person, (iii)
such Bearer Security is surrendered in exchange for a Registered Security or
(iv) such Bearer Security is no longer outstanding. The ownership of Bearer
Securities may also be proved in any other manner which the Trustee deems
sufficient.

                                       10
<PAGE>

                   (d) The ownership of Registered Securities shall be
proved by the Register.

                   (e) 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.

                   (f) If the Company shall solicit from the Holders of any
series any request, demand, authorization, direction, notice, consent, waiver or
other Act, the Company may, at its option, fix in advance a record date for the
determination of Holders of such series entitled to give such request, demand,
authorization, direction, notice, consent, waiver or other Act, but the Company
shall have no obligation to do so. 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 such series 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 of such series 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 of such
series 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 taken on or prior to the applicable Expiration Date (as
defined below) by Holders of the requisite amount of Outstanding Securities of
such series on such record date. Nothing in this paragraph shall be construed to
prevent the Company from setting a new record date for any action for which a
record date has previously been set pursuant to this paragraph (whereupon the
record date previously set shall automatically and with no action by any Person
be cancelled and of no effect), and nothing in this paragraph shall be construed
to render ineffective any action taken by Holders of the requisite amount of
Outstanding Securities on the date such action is taken. Promptly after any
record date is set pursuant to this paragraph, the Company, at its own expense,
shall cause notice of such record date, the proposed action by Holders and the
applicable Expiration Date to be given to the Trustee in writing and to each
Holder of Notes in the manner set forth in Section 1.6.

                   With respect to any record date set pursuant to this Section
1.4, the Company may designate any date as the "Expiration Date" and from time
to time may change the Expiration Date to any earlier or later day; provided
that no such change shall be effective unless notice of the proposed new
Expiration Date is given to the Trustee, and to each Holder of Securities of the
applicable series in the manner set forth in Section 1.6 on or prior to the
existing Expiration Date. If an Expiration Date is not designated with respect
to any record date pursuant to this Section, the Company shall be deemed to have
initially designated the 180th day after such record date as the Expiration Date
with respect thereto, subject to its right to change the Expiration Date as
provided in this paragraph. Notwithstanding the foregoing, no Expiration Date
shall be later than the 180th day after the applicable record date.

                                       11
<PAGE>

                   (g) Without limiting the foregoing, a Holder entitled
hereunder to take any action hereunder with regard to any particular Security
may do so with regard to all or any part of the principal amount of such
Security or by one or more duly appointed agents, each of which may do so
pursuant to such appointment with regard to all or any part of such principal
amount.

                   (h) The Company and the Trustee may make reasonable rules
for action by or at a meeting of Holders.

                   Section 1.5. Notices, etc., to Trustee and Company.  (a)
Any request, demand,authorization, direction, notice, consent, waiver or Act of
Holders or other document provided or permitted by this Indenture to be made
upon, given or furnished to, or filed with,

                   (1) the Trustee by any Holder or 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,
          Attention: Citibank Agency & Trust, 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 American Airlines, Inc.,
          P.O. Box 619616, Dallas/Fort Worth Airport, Texas 75261-9616,
          Attention: Treasurer, or at any other address previously furnished in
          writing to the Trustee by the Company.

                   (b) The Trustee shall promptly furnish the Company with a
copy of any report, demand, notice or written communication received by the
Trustee hereunder from, or sent or furnished by the Trustee hereunder to, any
Holder.

                   Section 1.6. Notice to Holders; Waiver. Where this Indenture
provides for notice to Holders of any event, (i) if any of the Securities
affected by such event are Registered Securities, such notice to the Holders
thereof shall be sufficiently given (unless otherwise herein or in the terms of
such Securities expressly provided) if in writing and mailed, first-class
postage prepaid, to each such Holder affected by such event, at its address as
it appears in the Register, within the time prescribed for the giving of such
notice and, (ii) if any of the Securities affected by such event are Bearer
Securities, notice to the Holders thereof shall be sufficiently given (unless
otherwise herein or in the terms of such Bearer Securities expressly provided)
if published once in an Authorized Newspaper in New York, New York, and in such
other city or cities, if any, as may be specified as contemplated by Section
3.1.

                   In any case where notice to Holders is given by mail, neither
the failure to mail such notice, nor any defect in any notice so mailed, to any
particular Holder shall affect the sufficiency of such notice with respect to
other Holders of Registered Securities or the sufficiency of any notice to
Holders of Bearer Securities given as provided herein. In any case where notice
is given to Holders by publication, neither the failure to publish such notice,
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

                                       12
<PAGE>

Registered Securities given as provided herein. 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.

                   If by reason of the suspension of regular mail service or by
reason of any other cause it shall be impracticable to give such notice as
provided above, then such notification as shall be made with the approval of the
Trustee (such approval not to be unreasonably withheld) shall constitute a
sufficient notification for every purpose hereunder. If it is impossible or, in
the opinion of the Trustee, impracticable to give any notice by publication in
the manner herein required, then such publication in lieu thereof as shall be
made with the approval of the Trustee shall constitute a sufficient publication
of such notice.

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

                   Any act or proceeding that is required or permitted by any
provision of this Indenture and that is authorized or required to be done or
performed by any board, committee or officer of the Company shall and may be
done and performed with like force and effect by the like board, committee or
officer of any corporation that shall at the time be the successor or assign of
the Company.

                   Section 1.9. Separability.  In case any provision of this
Indenture or the Securities shall be invalid, illegal or unenforceable, the
validity, legality and enforceability of the remaining provisions shall not in
any way be affected or impaired thereby.

                   Section 1.10. Benefits of Indenture. Nothing in this
Indenture or in the Securities, expressed or implied, shall give to any Person,
other than the parties hereto and their successors hereunder, any Agent and the
Holders, any benefit or any legal or equitable right, remedy or claim under this
Indenture.

                   Section 1.11. Governing Law. THIS INDENTURE, THE SECURITIES
AND ANY COUPONS APPERTAINING THERETO SHALL BE GOVERNED BY AND CONSTRUED IN

                                       13
<PAGE>

ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, INCLUDING ALL MATTERS OF
CONSTRUCTION, VALIDITY AND PERFORMANCE. This Indenture is subject to the Trust
Indenture Act and if any provision hereof limits, qualifies or conflicts with a
provision of the Trust Indenture Act that is required by the Trust Indenture Act
to be a part of and govern this Indenture, the latter provision shall control.
If any provision of this Indenture modifies or excludes any provision of the
Trust Indenture Act that may be so modified or excluded, the latter provision
shall be deemed to apply to this Indenture as so modified, or to be excluded, as
the case may be, whether or not such provision of this Indenture refers
expressly to such provision of the Trust Indenture Act.

                   Section 1.12. Legal Holidays. Unless otherwise provided with
respect to any Security or Securities pursuant to Section 3.1, in any case where
any Interest Payment Date, Redemption Date, sinking fund payment date, Stated
Maturity or Maturity or other payment date of any Security shall not be a
Business Day at any Place of Payment, then, notwithstanding any other provision
of this Indenture or any Security or coupon, payment of principal, premium, if
any or interest or other payments 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 such date; provided that no
interest shall accrue on the amount so payable for the period from and after
such Interest Payment Date, Redemption Date, sinking fund payment date, Stated
Maturity or Maturity or other payment date, as the case may be.

                   Section 1.13. No Recourse Against Others. No past, present or
future director, officer, employee, agent, member, manager, trustee or
stockholder, as such, of the Company, the Parent or any successor Person or any
Affiliate of any thereof shall have any liability for any obligations of the
Company, the Parent or any successor Person or any Affiliate of any thereof,
either directly or through the Company, the Parent or any successor Person or
any Affiliate of any thereof, under the Securities, this Indenture or any Parent
Guarantee or for any claim based on, in respect of or by reason of such
obligations or their creation, whether by virtue of any rule of law, statute or
constitutional provision or by the enforcement of any assessment or by any legal
or equitable proceeding or otherwise. By accepting a Security, each Holder
agrees to the provisions of this Section 1.13 and waives and releases all such
liability. Such waiver and release shall be part of the consideration for the
issue of the Securities.

                   Section 2.1. Forms Generally. The Securities of each series
and the coupons, if any, to be attached thereto shall be in substantially such
form 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 any applicable law, rule or regulation or with the rules
or usage of any securities exchange or Depositary therefor or as may,
consistently herewith, be determined by the officers executing such Securities
and coupons, if any, as evidenced by their execution of the Securities and
coupons, if any. If temporary Securities of any series are issued as permitted
by Section 3.4, the form thereof also shall be established as provided in the
preceding sentence. If the forms of Securities and coupons, if any, of any
series are established by, or by action taken pursuant to, a Board Resolution, a
copy of the Board Resolution together with an appropriate record of any such
action taken pursuant thereto, including a copy of the approved form of
Securities or coupons, if any, shall be certified by the Corporate Secretary or
an Assistant Secretary of the Company and delivered to the Trustee at or prior

authentication and delivery of such Securities.

                   Unless otherwise specified as contemplated by Section 3.1,
Bearer Securities shall have interest coupons attached.

                   The definitive Securities and coupons, if any, may be
typeset, printed, lithographed or engraved on steel engraved borders or may be
produced in any other manner or medium, all as determined by the officers
executing such Securities and coupons, if any, as evidenced by their execution

                  Section 2.3. Securities in Global Form. If Securities of or
within a series are issuable in whole or in part in global form, any such
Security may provide that it shall represent the aggregate or specified amount
of Outstanding Securities from time to time endorsed thereon and may also
provide that the aggregate amount of Outstanding Securities represented thereby
may from time to time be reduced or increased to reflect exchanges. Any
endorsement of a Security in global form to reflect the amount, or any increase
or decrease in the amount, or changes in the rights of Holders, of Outstanding
Securities represented thereby, shall be made in such manner and by such Person
or Persons as shall be specified therein or in the Company Order to be delivered
to the Trustee pursuant to Section 3.3 or 3.4. Subject to the provisions of
Section 3.3 and, if applicable, Section 3.4, 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. 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 1.2 hereof and need not be accompanied
by an Opinion of Counsel.

                  The provisions of the last paragraph of Section 3.3 shall
apply to any 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 1.2
and need not be accompanied by an Opinion of Counsel) with regard to the
reduction in the principal amount of Securities represented thereby, together
with the written statement contemplated by the last sentence of Section 3.3.

                  Notwithstanding the provisions of Section 2.1 and 3.7, unless
otherwise specified as contemplated by Section 3.1, payment of principal of,
premium, if any, and interest on any Security in permanent global form shall be
made to the Person or Persons specified therein.

                   Section 2.4. Form of Legend for Securities in Global Form.
Unless otherwise provided with respect to any Securities of any series pursuant
to Section 3.1 or required by the Depositary, any Security of such series in
global form authenticated and delivered hereunder shall bear a legend in
substantially the following form:

                   This Security is in global form within the meaning of the
         Indenture hereinafter referred to and is registered in the name of a
         Depositary or a nominee of a Depositary. Unless and until it is
         exchanged in whole or in part for Securities in certificated form, this
         Security may not be transferred except as a whole by the Depositary to
         a nominee of the Depositary or by a nominee of the Depositary to the
         Depositary or another nominee of the Depositary or by the Depositary or
         any such nominee to a successor Depositary or a nominee of such
         successor Depositary. Every Security authenticated and delivered upon
         registration of transfer of, or in exchange for, or in lieu of, this
         Security will be in global form, subject to the foregoing.

         commodities exchange indices or other indices; a currency or currencies
         (including composite currency or currencies or currency unit or units)

         shall be determined;

          whom any interest on any Registered Security of the series shall be
          payable and the manner in which, or the Person to whom, any interest

          thereunder, or, if other than as provided in the definition of the
          term "Outstanding", which shall be deemed to be Outstanding as of any

          additional amounts on the Securities of that series held by a Person
          who is not a U.S. Person in respect of taxes or similar charges
          withheld or deducted 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);

                  (18) whether Securities of the series shall be issuable as

          Securities and coupons, if any, of such series, and whether, for the
          purpose

          4.5 or otherwise, the term "Government Obligations" shall
          include obligations referred to in the definition of such term which

          that in Section 2.4 which shall be borne by such global Securities,
          (iii) whether beneficial owners of interests in any Securities of the
          series in global form may exchange such interests for certificated
          Securities of such series and of like tenor of any authorized form and
          denomination, and (iv) if other than as provided in Section 3.5, the
          circumstances under which any such exchange may occur;

                  (26) if the Securities of the series will be governed by, and

          than the laws of the state of New York;

                  (27) whether the Parent will guarantee the obligations of the
          Company under the Securities of such series and if so, the specific
          form of such Parent Guarantee or Parent Guarantees, any related
          modifications, amendments, supplements or deletions of any of the
          terms of this Indenture, and a statement that the Parent shall be an
          "obligor" as such term is defined in and solely for purposes of the
          Trust Indenture Act and shall be required to comply with those

          of the Trust Indenture Act, but may modify, amend, supplement or
          delete any of the terms of this Indenture with respect to such
          series), including any terms which may be required by or advisable
          under United States laws or regulations or advisable (as determined by
          the Company) in connection with the marketing of Securities of the
          series;

provided, that if the Parent will guarantee the obligations of the Company under
the Securities of a series, such matters shall be established in one or more
indenture supplements hereto to which the Company, the Parent and the Trustee
shall be a party.

                  (c) The terms applicable to the Securities of any one series
and coupons, if any, appertaining to any Bearer Securities of such series need
not be identical but may vary as may be provided (i) by a Board Resolution, (ii)
by action taken pursuant to a Board Resolution and (subject to Section 3.3) set
forth, or determined in the manner provided, in the related Officers'
Certificate or (iii) in an indenture supplemental hereto. All Securities of any
one series need not be issued at the same time and, unless otherwise provided, a
series may be reopened, without the consent of the Holders, for issuances of
additional Securities of such series.

                  (d) If any of the terms of the Securities of any series are
established by action taken pursuant to a Board Resolution, a copy of such Board
Resolution shall be certified by the Corporate Secretary or an Assistant
Secretary of the Company and delivered to the Trustee at or prior to the
delivery of the Officers' Certificate setting forth, or providing the manner for
determining, the terms of the Securities of such series, and an appropriate
record of any action taken pursuant thereto in connection with the issuance of
any Securities of such series shall be delivered to the Trustee prior to the
authentication and delivery thereof.

                   Section 3.2. Denominations. Unless otherwise provided as
contemplated by Section 3.1, any Registered Securities of a series shall be
issuable in denominations of $1,000 and any integral multiple thereof and any
Bearer Securities of a series shall be issuable in the denomination of $5,000
and any integral multiple thereof.

                   Section 3.3. Execution, Authentication, Delivery and Dating.
Securities shall be executed on behalf of the Company by the Chairman of the
Board, the Vice Chairman of the Board of Directors, the President, any Executive
Vice President, any Senior Vice President or any Vice President. The Company's
seal shall be reproduced (which may be via facsimile) on the Securities and
shall be attested by the Corporate Secretary or any Assistant Secretary. The
signatures of any of these officers on the Securities may be manual or
facsimile. The coupons, if any, of Bearer Securities shall bear the facsimile
signature of the Chairman of the Board, the Vice Chairman of the Board of
Directors, the President, any Executive Vice President, any Senior Vice
President, any Vice President, the Treasurer or any Assistant Treasurer of the
Company.

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

                   At any time and from time to time, the Company may deliver
Securities, together with any coupons appertaining thereto, of any series
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 the Company Order shall authenticate and deliver such
Securities; provided, however, that in the case of Securities offered in a
Periodic Offering, the Trustee shall authenticate and deliver such

                                       21
<PAGE>

Securities from time to time in accordance with such other procedures
(including, without limitation, the receipt by the Trustee of electronic
instructions from the Company or its duly authorized agents, promptly confirmed
in writing) acceptable to the Trustee as may be specified by or pursuant to a
Company Order delivered to the Trustee prior to the time of the first
authentication of Securities of such series.

                   If the form or terms of the Securities of a series have been
established by or pursuant to one or more Board Resolutions as permitted by
Sections 2.1 and 3.1, 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 section 315(a) through
(d) of the Trust Indenture Act) shall be fully protected in relying upon, an
Opinion of Counsel substantially to the effect that,

                  (1) if the forms of such Securities and any coupons have been
         established by or pursuant to a Board Resolution as permitted by
         Section 2.1, such forms have been established in conformity with the
         provisions of this Indenture;

                  (2) if the terms of such Securities and any coupons have been
         established by or pursuant to a Board Resolution as permitted by
         Section 3.1, such terms have been, or in the case of Securities of a
         series offered in a Periodic Offering, will be, established in
         conformity with the provisions of this Indenture, subject in the case
         of Securities offered in a Periodic Offering, to any conditions
         specified in such Opinion of Counsel; and

                  (3) such Securities together with any coupons appertaining
          thereto, when authenticated and delivered by the Trustee and issued by
          the Company in the manner and subject to any conditions specified in
          such Opinion of Counsel, will constitute legal, valid and binding
          obligations of the Company, enforceable in accordance with their
          terms, subject to bankruptcy, insolvency, fraudulent transfer,
          reorganization, moratorium and other similar laws of general
          applicability relating to or affecting the enforcement of creditors'
          rights and to general equity principles and except as may be further
          limited by or subject to certain exceptions and qualifications
          specified in such Opinion of Counsel, including in the case of any
          Securities denominated in a Foreign Currency, (A) requirements that a
          claim with respect to any Securities denominated other than in Dollars
          (or a foreign currency or foreign composite currency or currency unit
          judgment in respect of such claim) be converted into Dollars at a rate
          of exchange prevailing on a date determined pursuant to applicable law
          or (B) governmental authority to limit, delay or prohibit the making
          of payments in foreign currency or currency units or payments outside
          the United States.

                  Notwithstanding that such form or terms have been so
established, the Trustee shall have the right but not the obligation to decline
to authenticate such Securities if, in the written opinion of counsel to the
Trustee (which counsel may be an employee of the Trustee) reasonably acceptable
to the Company, the issue of such Securities pursuant to this Indenture will
adversely affect the Trustee's own rights, duties or immunities under this
Indenture or otherwise in a manner which is not reasonably acceptable to the
Trustee. Notwithstanding the generality of the foregoing, the Trustee will not
be required to authenticate

                                       22
<PAGE>

Securities denominated in a Foreign Currency if the Trustee reasonably believes
that it would be unable to perform its duties with respect to such Securities.

                   Notwithstanding the provisions of Section 3.1 and of the two
preceding paragraphs, if all of the Securities of any series are not to be
issued at one time, it shall not be necessary to deliver the Officers'
Certificate otherwise required pursuant to Section 3.1 or the Company Order and
Opinion of Counsel otherwise required pursuant to the two preceding paragraphs
in connection with the authentication of each Security of such series if such
documents, with appropriate modifications to cover such future issuances, are
delivered at or prior to the authentication upon original issuance of the first
Security of such series to be issued.

                   With respect to Securities of a series offered in a Periodic
Offering, the Trustee may rely, as to the authorization by the Company of any of
such Securities, the form and terms thereof and the legality, validity, binding
effect and enforceability thereof, upon the Opinion of Counsel and the other
documents delivered pursuant to Sections 2.1 and 3.1 and this Section, as
applicable, in connection with the first authentication of Securities of such
series.

                   If the Company shall establish pursuant to Section 3.1 that
the Securities of a series are to be issued in whole or in part in global form,
then, unless otherwise provided with respect to such Securities pursuant to
Section 3.1, the Company shall execute and the Trustee shall, in accordance with
this Section and the Company Order with respect to such series, authenticate and
deliver one or more Securities in global form that (i) shall represent and shall
be denominated in an amount equal to the aggregate principal amount of the
Outstanding Securities of such series to be represented by such Security or
Securities in global form, (ii) shall be registered, if a Registered Security,
in the name of the Depositary for such Security or Securities in global form or
the nominee of such Depositary, (iii) shall be delivered by the Trustee to such
Depositary or pursuant to such Depositary's instruction and (iv) shall bear the
legend set forth in Section 2.4.

                   Unless otherwise established pursuant to Section 3.1, each
Depositary designated pursuant to Section 3.1 for a Registered Security in
global form must, at the time of its designation and at all times while it
serves as Depositary, be a clearing agency registered under the Securities
Exchange Act of 1934 and any other applicable statute or regulation. Neither the
Company nor the Trustee shall have any responsibility to determine if the
Depositary is so registered.

                  Each Depositary shall enter into an agreement with the Trustee
governing the respective duties and rights of such Depositary and the Trustee
with regard to Securities issued in global form.

                  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 3.1.

                                       23
<PAGE>

                  No Security or coupon appertaining thereto shall be entitled
to any benefits under this Indenture or be valid or obligatory for any purpose
until authenticated by the manual signature of one of the authorized signatories
of the Trustee or an Authenticating Agent and no coupon shall be valid until the
Security to which it appertains has been so authenticated. Such signature upon
any Security shall be conclusive evidence, and the only evidence, that such
Security has been duly authenticated and delivered under this Indenture and is
entitled to the benefits of this Indenture. Except as permitted by Section 3.6
or 3.7, the Trustee shall not authenticate and deliver any Bearer Security
unless all appurtenant coupons for interest then matured have been detached and
cancelled.

                  Notwithstanding the foregoing, if any 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 3.9 together with a written statement (which need not comply
with Section 1.2 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 not 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 of such
series which are printed, lithographed, typewritten, mimeographed or otherwise
produced, in any authorized denomination, substantially of the tenor and form,
with or without coupons, of the definitive Securities in lieu of which they are
issued 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 and coupons, if
any. In the case of Securities of any series, all or a portion of such temporary
Securities may be in global form.

                   Except in the case of temporary Securities in global form,
each of which shall be exchanged in accordance with the provisions thereof, if
temporary Securities of any series are issued, the Company will cause definitive
Securities of such series to be prepared without unreasonable delay. After
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 pursuant to Section 9.2 in a Place of Payment for such 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 and of like
tenor; provided, however, that no definitive Bearer Security shall be delivered
in exchange for a temporary Registered Security; and provided further that no
definitive Bearer Security shall be delivered in exchange for a temporary Bearer
Security unless the Trustee shall have received from the person entitled to
receive the definitive Bearer Security a certificate substantially in the form
approved in or pursuant to the Board Resolutions relating thereto and such
delivery shall occur only outside the United States. 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 except as
otherwise specified as contemplated by Section 3.1.

                  Section 3.5. Registration, Transfer and Exchange. The Company
shall cause to be kept at the Corporate Trust Office of the Trustee or in any
office or agency to be maintained by the Company in accordance with Section 9.2
in a Place of Payment or in such other place or medium as may be specified
pursuant to Section 3.1 a register (the "Register") in which, subject to such
reasonable regulations as it may prescribe, the Company shall provide for the
registration of Registered Securities and the registration of transfers of
Registered Securities. The Register shall be in written form or any other form
capable of being converted into written form within a reasonable time. Unless
otherwise provided as contemplated by Section 3.1, the Trustee is hereby
appointed "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 maintained pursuant to Section
9.2 in a Place of Payment for that series, the Company shall execute, and the
Trustee shall authenticate and deliver, in the name of the designated transferee
or transferees, one or more new Registered Securities of the same series, of any
authorized denominations and of a like aggregate principal amount.

                   Unless otherwise provided as contemplated by Section 3.1,
Bearer Securities (except for any temporary global Bearer Securities) or any
coupons appertaining thereto (except for coupons attached to any temporary
global Bearer Security) shall be transferable by delivery.

                   Unless otherwise provided as contemplated by Section 3.1, at
the option of the Holder, Registered Securities of any series (except a
Registered Security in global form) may be exchanged for other Registered
Securities of the same series, of any authorized denominations and of a like
aggregate principal amount containing identical terms and provisions, 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 as contemplated by Section 3.1, Bearer Securities may not be
issued in exchange for Registered Securities.

                   Unless otherwise specified as contemplated by Section 3.1, at
the option of the Holder, Bearer Securities of such series may be exchanged for
Registered Securities (if the Securities of such series are issuable in
registered form) or Bearer Securities (if Bearer Securities of such series are
issuable in more than one denomination and such exchanges are permitted by such
series) of the same series, of any authorized denominations and of like tenor
and aggregate principal amount, upon surrender of the Bearer Securities to be
exchanged at any such office or agency, with all unmatured coupons and all
matured coupons in default thereto appertaining. If the Holder of a Bearer
Security is unable to produce any such unmatured coupon or coupons or matured
coupon or coupons in default, such exchange may be effected if the Bearer
Securities are accompanied by payment in funds acceptable to the Company and the
Trustee in an amount equal to the face amount of such missing coupon or coupons,
or the surrender of such missing

                                       25
<PAGE>

coupon or coupons may be waived by the Company and the Trustee if there be
furnished to them such security or indemnity as they may require to save each of
them and any Paying Agent harmless. If thereafter the Holder of such Security
shall surrender to any Paying Agent any such missing coupon in respect of which
such a payment shall have been made, such Holder shall be entitled to receive
the amount of such payment; provided, however, that, except as otherwise
provided in Section 9.2, 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 any Bearer
Security of any series is surrendered at any such office or agency in exchange
for a Registered Security of the same series after the close of business at such
office or agency on (i) any Regular Record Date and before the opening of
business at such office or agency on the relevant Interest Payment Date, or (ii)
any Special Record Date and before the opening of business at such office or
agency on the related date for payment of Defaulted Interest, such Bearer
Security shall be surrendered without the coupon relating to such Interest
Payment Date or proposed date of payment, as the case may be (or, if such coupon
is so surrendered with such Bearer Security, such coupon shall be returned to
the person so surrendering the Bearer Security), and interest or Defaulted
Interest, as the case may be, will not be payable on such Interest Payment Date
or proposed date for payment, as the case may be, in respect of the Registered
Security issued in exchange for such Bearer Security, but will be payable only
to the Holder of such coupon, when due in accordance with the provisions of this
Indenture.

                   Unless otherwise specified pursuant to Section 3.1 with
respect to a series of Securities or as otherwise provided below in this Section
3.5, owners of beneficial interests in Securities of such series represented by
a Security issued in global form will not be entitled to have Securities of such
series registered in their names, will not receive or be entitled to receive
physical delivery of Securities of such series in certificated form and will not
be considered the Holders or owners thereof for any purposes hereunder.
Notwithstanding any other provision of this Section, unless and until it is
exchanged in whole or in part for Securities in certificated form in the
circumstances described below, a Security in global form representing all or a
portion of the Securities of a series may not be transferred or exchanged except
as a whole by the Depositary for such series to a nominee of such Depositary or
by a nominee of such Depositary to such Depositary or another nominee of such
Depositary or by such Depositary or any such nominee to a successor Depositary
for such series or a nominee of such successor Depositary.

                   If at any time the Depositary for the Securities of a series
notifies the Company that it is unwilling or unable to continue as Depositary
for the Securities of such series or if at any time the Depositary for the
Securities of such series notifies the Company that it shall no longer be
eligible under Section 3.3, the Company shall appoint a successor Depositary
with respect to the Securities of such series. Unless otherwise provided as
contemplated by Section 3.1, if a successor Depositary for the Securities of
such series is not appointed by the Company within 90 days after the Company
receives such notice or becomes aware of such ineligibility, the Company's
election pursuant to Section 3.1(b) (25) shall no longer be effective with
respect to the Securities of such series and the Company shall execute, and the
Trustee, upon receipt of a Company Order for the authentication and delivery of
certificated Securities of such series of like tenor, shall authenticate and
deliver, Securities of such series of like tenor in certificated

                                       26

form, in authorized denominations and in an aggregate principal amount equal to
the principal amount of the Security or Securities of such series of like tenor
in global form in exchange for such Security or Securities in global form.

                   The Company may at any time in its sole discretion determine
that Securities of a series issued in global form shall no longer be represented
by such a Security or Securities in global form. In such event the Company shall
execute, and the Trustee, upon receipt of a Company Order for the authentication
and delivery of certificated Securities of such series of like tenor, shall
authenticate and deliver, Securities of such series of like tenor in
certificated form, in authorized denominations and in an aggregate principal
amount equal to the principal amount of the Security or Securities of such
series of like tenor in global form in exchange for such Security or Securities
in global form.

                   If specified by the Company pursuant to Section 3.1 with
respect to a series of Securities, the Depositary for such series may surrender
a Security in global form of such series in exchange in whole or in part for
Securities of such series in certificated form on such terms as are acceptable
to the Company and such Depositary. Thereupon, the Company shall execute, and
the Trustee shall authenticate and deliver, without service charge,

                   (i) to each Person specified by such Depositary a new
          certificated Security or Securities of the same series of like tenor,
          of any authorized denomination as requested by such Person in
          aggregate principal amount equal to and in exchange for such Person's
          beneficial interest in the Security in global form; and

                   (ii) to such Depositary a new Security in global form of like
          tenor in a denomination equal to the difference, if any, between the
          principal amount of the surrendered Security in global form and the
          aggregate principal amount of certificated Securities delivered to
          Holders thereof.

                   Upon the exchange of a Security in global form for Securities
in certificated form, such Security in global form shall be cancelled by the
Trustee. Unless expressly provided with respect to the Securities of any series
that such Security may be exchanged for Bearer Securities, Securities in
certificated form issued in exchange for a Security in global form pursuant to
this Section shall be registered in such names and in such authorized
denominations as the Depositary for such Security in global form, pursuant to
instructions from its direct or indirect participants or otherwise, shall
instruct the Trustee. The Trustee shall deliver such Securities to the Persons
in whose names such Securities are so registered.

                   Whenever any Securities are 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.

                   All Securities issued upon any registration of transfer or
upon any 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.

                                       27
<PAGE>

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

                   Unless otherwise provided as contemplated by Section 3.1, no
service charge shall be made for any registration of transfer or for any
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 3.4 or 10.7 not involving any transfer.

                   Unless otherwise provided as contemplated by Section 3.1, the
Company shall not be required (i) to issue, register the transfer of, or
exchange any Securities for a period beginning at the opening of business 15
days before any selection for redemption of Securities of like tenor and of the
series of which such Security is a part and ending at the close of business on
the earliest date on which the relevant notice of redemption is deemed to have
been given to all Holders of Securities of like tenor and of such series to be
redeemed; (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.

                   Section 3.6. Replacement Securities. If a mutilated Security
or a Security with a mutilated coupon appertaining to it is surrendered to the
Trustee, together with, in proper cases, such security or indemnity as may be
required by the Company or the Trustee to save each of them harmless, the
Company shall execute and the Trustee shall authenticate and deliver a
replacement Registered Security, if such surrendered Security was a Registered
Security, or a replacement Bearer Security with coupons corresponding to the
coupons appertaining to the surrendered Security, if such surrendered Security
was a Bearer Security, of the same series and date of maturity, if the Trustee's
requirements are met.

                   If there shall be delivered to the Company and the Trustee
(i) evidence to their satisfaction of the destruction, loss or theft of any
Security or Security with a destroyed, lost or stolen 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 proof satisfactory to
the Company or the Trustee that such Security or coupon has been acquired by a
bona fide purchaser, the Company shall execute and the Trustee shall
authenticate and deliver in lieu of any such destroyed, lost or stolen Security
or in exchange for the Security to which a destroyed, lost or stolen coupon
appertains (with all appurtenant coupons not destroyed, lost or stolen), a
replacement Registered Security, if such Holder's claim appertains to a
Registered Security,

                                       28
<PAGE>

or a replacement Bearer Security with coupons corresponding to the coupons
appertaining to the destroyed, lost or stolen Bearer Security or the Bearer
Security to which such lost, destroyed or stolen coupon appertains, if such
Holder's claim appertains to a Bearer Security, of the same series and principal
amount, containing identical terms and provisions and bearing a number not
contemporaneously outstanding with coupons corresponding to the coupons, if any,
appertaining to the destroyed, lost or stolen Security.

                   In case any such mutilated, destroyed, lost or stolen
Security or coupon has become or is about to become due and payable, the Company
in its discretion may, instead of issuing a new Security or coupon, pay such
Security or coupon; provided, however, that payment of principal of and any
premium or interest on Bearer Securities shall, except as otherwise provided in
Section 9.2, be payable only at an office or agency located outside the United
States and, unless otherwise specified as contemplated by Section 3.1, any
interest on Bearer Securities shall be payable only upon presentation and
surrender of the coupons appertaining thereto.

                   Upon the issuance of any new Security under this Section, the
Company may require the payment of a sum sufficient to 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, its agents and
counsel) 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 coupon, 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.

                   Unless otherwise provided as contemplated by Section 3.1, 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.
(a) Unless otherwise provided as contemplated by Section 3.1, interest, if any,
on any Registered Security which is payable, and is punctually paid or duly
provided for, on any Interest Payment Date shall be paid to the Person in whose
name that 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 maintained for such purpose pursuant to 9.2; provided, however, that at
the option of the Company, interest on any series of Registered Securities that
bear interest may be paid (i) by check mailed to the address of the Person
entitled thereto as it shall appear on the Register of Holders of Securities of
such series or (ii) by wire transfer to an account maintained by the Person
entitled thereto as specified in the Register of Holders of Securities of such
series.

<PAGE>

                   Unless otherwise provided as contemplated by Section 3.1, (A)
(i) interest, if any, on Bearer Securities shall be paid only against
presentation and surrender of the coupons for such interest installments as are
evidenced thereby as they mature and (ii) principal, original issue discount, if
any, and premium, if any, on Bearer Securities shall be paid only against
presentation and surrender of such Securities; in either case at the office of a
Paying Agent located outside the United States, unless the Company shall have
otherwise instructed the Trustee in writing, provided that any such instruction
for payment in the United States does not cause any Bearer Security to be
treated as a "registration-required obligation" under United States laws and
regulations; (B) the interest, if any, on any temporary Bearer Security shall be
paid, as to any installment of interest evidenced by a coupon attached thereto
only upon presentation and surrender of such coupon as provided in clause (A)
above and, as to other installments of interest, only upon presentation of such
Security for notation thereon of the payment of such interest; and (C) if at the
time a payment of principal of, premium, if any, or interest, if any, on a
Bearer Security or coupon shall become due, the payment of the full amount so
payable at the office or offices of all the Paying Agents outside the United
States is illegal or effectively precluded because of the imposition of exchange
controls or other similar restrictions on the payment of such amount in Dollars,
then the Company may instruct the Trustee to make such payment at a Paying Agent
located in the United States, provided that provision for such payment in the
United States would not cause such Bearer Security to be treated as a
"registration-required obligation" under United States laws and regulations.

                   (b) Unless otherwise provided as contemplated by Section 3.1,
any interest on any Registered Security of any series which is payable, but is
not punctually paid or duly provided for, on any interest payment date (herein
called "Defaulted Interest") shall forthwith cease to be payable to the Holder
on the relevant Regular Record Date by virtue of having been such Holder, and
such Defaulted Interest may be paid by the Company, at its election in each
case, as provided in clause (1) or (2) below:

                   (1) The Company may elect to make payment of any Defaulted
          Interest to the Persons in whose names such 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 deposit with the Trustee an amount
          of money equal to the aggregate amount proposed to be paid in respect
          of such Defaulted Interest or shall make arrangements satisfactory to
          the Trustee for such deposit 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
          (1) provided. Thereupon the Trustee shall fix a Special Record Date
          for the payment of such Defaulted Interest which shall be not more
          than 15 days and not less than 10 days prior to the date of the
          proposed payment and not less than 10 days after the receipt by the
          Trustee of the notice of the proposed payment. The Trustee shall
          promptly notify the Company of such Special Record Date and, in the
          name and at the expense of the Company, shall cause notice of the
          proposed payment of such Defaulted Interest and the Special Record
          Date therefor to be mailed, first-class postage prepaid, to each
          Holder of such Registered Securities of such series at his address as
          it appears in the Register, not less than 10 days prior to such
          Special Record Date. Notice of the proposed payment of such

                                       30
<PAGE>
          Defaulted Interest and the Special Record Date therefor having been so
          mailed, such Defaulted Interest shall be paid to the Persons in whose
          names such 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).

                   (2) The Company may make payment of any Defaulted Interest to
          the Persons in whose names such Registered Securities of such series
          (or their respective Predecessor Securities) are registered at the
          close of business on a specified date in any other lawful manner not
          inconsistent with the requirements of any securities exchange on which
          such Registered Securities may be listed, and upon such notice as may
          be required by such exchange, if, after notice given by the Company to
          the Trustee of the proposed payment pursuant to this clause (2), such
          manner of payment shall be deemed practicable by the Trustee.

                   (c) Subject to the foregoing provisions of this Section and
Section 3.5, each Security delivered under this Indenture upon registration of
transfer of or in exchange for or in lieu of any other Security shall carry the
rights to interest accrued and unpaid, and to accrue, which were carried by such
other Security.

                   Section 3.8. Persons Deemed Owners. Prior to due presentment
of any 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,
premium, if any, and (subject to Section 3.7) interest and any other payments on
such Registered Security and for all other purposes whatsoever, whether or not
such Registered Security shall be overdue, and neither the Company, the Trustee
nor any agent of the Company or the Trustee shall be affected by notice to the
contrary.

                   The Company, the Trustee and any agent of the Company or the
Trustee may treat the bearer of any Bearer Security and the bearer of any coupon
as the absolute owner of such Bearer Security or coupon for the purpose of
receiving payment thereof or on account thereof and for all other purposes
whatsoever, whether or not such Bearer Security or coupon be overdue, and
neither the Company, the Trustee nor any agent of the Company or the Trustee
shall be affected by notice to the contrary.

                   None of the Company, the Trustee or any agent of the Company
or the Trustee shall 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 Security in global form,
nothing herein shall prevent the Company or 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 (or its nominee), as a
Holder, with respect to such Security in global form or impair, as between such
Depositary and owners of beneficial interests in such Security in global form,
the operation of customary practices governing the exercise of the rights of
such Depositary (or its nominee) as Holder of such Security in global form.

                                       31
<PAGE>

                   Unless otherwise provided with respect to any Securities
pursuant to Section 3.1, the Company, the Parent, any other obligor upon any
Securities and any Affiliate of any thereof may acquire, tender for, purchase,
own, hold, become the pledgee of and otherwise deal with any Securities.

                   Section 3.9. Cancellation. The Company at any time may
deliver Securities and coupons to the Trustee for cancellation. The Registrar
and any Paying Agent shall forward to the Trustee any Securities and coupons
surrendered to them for replacement, for registration of transfer, or for
exchange or payment. The Trustee shall cancel all Securities and coupons
surrendered for replacement, for registration of transfer, or for exchange,
payment, redemption or cancellation and shall dispose of such cancelled
Securities in its customary manner. The Company may not issue new Securities to
replace Securities that it has paid or delivered to the Trustee for
cancellation.

                   Section 3.10. Computation of Interest. Except as otherwise
specified as contemplated by Section 3.1, interest on the Securities of each
series shall be computed on the basis of a 360-day year of twelve 30-day months.

                   Section 3.11. Currency and Manner of Payment in Respect of
Securities. (a) Unless otherwise specified with respect to any Securities
pursuant to Section 3.1, 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, premium, if any, interest, if any, and other
amounts, if any, on any Registered Security or Bearer Security of such series
will be made in the currency or currencies or currency unit or units in which
such Registered Security or Bearer Security, as the case may be, is payable. The
provisions of this Section 3.11, including, without limitation, any defined
terms specified herein, may be modified or superseded in whole or in part
pursuant to Section 3.1 with respect to any Securities.

                   (b) It may be provided pursuant to Section 3.1, 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,
premium, if any, or interest, if any, on such Registered Securities in any of
the currencies or currency units which may be designated for such election by
delivering to the Trustee (or the applicable Paying Agent) a written election
with signature guarantees and in the applicable form established pursuant to
Section 3.1, 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 or currency unit, 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 (or any
applicable Paying Agent) for such series of Registered Securities (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

                                       32
<PAGE>

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 IV or with respect to which a notice of redemption has been
given by or on behalf of the Company). Any Holder of any such Registered
Security who shall not have delivered any such election to the Trustee (or any
applicable Paying Agent) 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 or currency unit as provided in Section 3.11(a). The Trustee
(or the applicable Paying Agent) shall notify the Company and 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) If the election referred to in paragraph (b) above has
been provided for with respect to any Registered Securities of a series pursuant
to Section 3.1, then, unless otherwise specified pursuant to Section 3.1 with
respect to any such Registered Securities, not later than the fourth Business
Day after the Election Date for each payment date for such Registered
Securities, the Exchange Rate Agent will deliver to the Company a written notice
specifying, in the currency or currencies or currency unit or units in which
Registered Securities of such series are payable, the respective aggregate
amounts of principal of, premium, if any, and interest, if any, on such
Registered Securities to be paid on such payment date, and specifying the
amounts in such currency or currencies or currency unit or units so payable in
respect of such Registered Securities as to which the Holders of Registered
Securities denominated in any currency or currencies or currency unit or units
shall have elected to be paid in another currency or currency unit as provided
in paragraph (b) above. If the election referred to in paragraph (b) above has
been provided for with respect to any Registered Securities of a series pursuant
to Section 3.1, and if at least one Holder has made such election, then, unless
otherwise specified pursuant to Section 3.1, on the second Business Day
preceding such payment date the Company will deliver to the Trustee (or the
applicable Paying Agent) an Exchange Rate Officers' Certificate in respect of
the Dollar, Foreign Currency or Currencies or other currency unit payments to be
made on such payment date. Unless otherwise specified pursuant to Section 3.1,
the Dollar, Foreign Currency or Currencies or other currency unit amount
receivable by Holders of Registered Securities who have elected payment in a
currency or currency unit 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 second 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 Conversion Event occurs with respect to a Foreign
Currency or any other currency unit in which any of the Securities are
denominated or payable otherwise than pursuant to an election provided for
pursuant to paragraph (b) above, then, unless otherwise specified pursuant to
Section 3.1, with respect to each date for the payment of principal of, premium,
if any, and interest, if any, on the applicable Securities denominated or
payable in such Foreign Currency or such other currency unit occurring after the
last date on which such Foreign Currency or such other currency unit was used
(the "Conversion Date"), the Dollar shall be the currency of payment for use on
each such payment date (but such Foreign Currency or such other currency unit
that was previously the currency of payment shall, at

                                       33
<PAGE>

the Company's election, resume being the currency of payment on the first such
payment date preceded by 15 Business Days during which the circumstances which
gave rise to the Dollar becoming such currency of payment no longer prevail).
Unless otherwise specified pursuant to Section 3.1, the Dollar amount to be paid
by the Company to the Trustee or any applicable Paying Agent and by the Trustee
or any applicable 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 Foreign Currency that is 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 3.1, if
the Holder of a Registered Security denominated in any currency or currency unit
shall have elected to be paid in another currency or currency unit or in other
currencies as provided in paragraph (b) above, and (i) a Conversion Event occurs
with respect to any such elected currency or currency unit, such Holder shall
receive payment in the currency or currency unit in which payment would have
been made in the absence of such election and (ii) if a Conversion Event occurs
with respect to the currency or currency unit 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) of this Section 3.11 (but, subject to any
contravening valid election pursuant to paragraph (b) above, the elected payment
currency or currency unit, in the case of the circumstances described in clause
(i) above, or the payment currency or currency unit in the absence of such
election, in the case of the circumstances described in clause (ii) above,
shall, at the Company's election, resume being the currency or currency unit of
payment with respect to Holders who have so elected, but only with respect to
payments on payment dates preceded by 15 Business Days during which the
circumstances which gave rise to such currency or currency unit, in the case of
the circumstances described in clause (i) above, or the Dollar, in the case of
the circumstances described in clause (ii) above, becoming the currency or
currency unit, as applicable, of payment, no longer prevail).

                   (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 the Exchange Rate Agent by converting the specified Foreign
Currency into Dollars at the Market Exchange Rate on the 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 (as each such term is defined in
paragraph (h) below) 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 3.11, the following
terms shall have the following meanings:

                                       34
<PAGE>

                   A "Component Currency" shall mean any currency which, on the
Conversion Date, was a component currency of the relevant currency unit.

                   "Conversion Event" shall mean the cessation of use of (i) a

quotation, signed by the Chairman of the Board, the Vice Chairman of the Board
of Directors, the President, the Chief Financial Officer, any Executive Vice

Assistant Treasurer of the Company.

                   "Foreign Currency" shall mean any currency issued by the
government or governments of one or more countries other than the United States

include the Euro.

                   "Market Exchange Rate" shall mean, unless otherwise specified
with respect to any Securities pursuant to Section 3.1, as of any date of
determination, (i) for any conversion involving a currency unit on the one hand
and Dollars or any Foreign Currency on the other, the exchange rate between the
relevant currency unit and Dollars or such Foreign Currency calculated by the

<PAGE>

Foreign Currency into which conversion is being made could be purchased with the
Foreign Currency from which conversion is being made from major banks located in
New York City, London or any other principal market for Dollars or such
purchased Foreign Currency, in each case determined by the Exchange Rate Agent.
Unless otherwise specified with respect to any Securities pursuant to Section

for in the foregoing clauses (i), (ii) and (iii), the Exchange Rate Agent shall
use, in its sole discretion and without liability on its part, such quotation of

Component Currency represented in the relevant currency unit on the Conversion
Date. If after the Conversion Date the official unit of any Component Currency
is altered by way of combination or subdivision, the Specified Amount of such

after the Conversion Date two or more Component Currencies are consolidated into
a single currency, the respective Specified Amounts of such Component Currencies
shall be replaced by an amount in such single currency equal to the sum of the
respective Specified Amounts of such consolidated Component Currencies expressed
in such single currency, and such amount shall thereafter be a Specified Amount
and such single currency shall thereafter be a Component Currency. If after the
Conversion Date any Component Currency shall be divided into two or more
currencies, the Specified Amount of such Component Currency shall be replaced by
specified amounts of such two or more currencies, the sum of which, at the
Market Exchange Rate of such two or more currencies on the date of such
replacement, shall be equal to the Specified Amount of such former Component
Currency and such amounts shall thereafter be Specified Amounts and such
currencies shall thereafter be Component Currencies. If, after the Conversion
Date of the relevant currency unit, a Conversion Event (other than any event
referred to above in this definition of "Specified Amount") occurs with respect
to any Component Currency of such currency unit 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
Conversion Date of such Component Currency.

                    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 any applicable Paying Agent) and all
Holders of Securities denominated or payable in the

                                       36

<PAGE>

relevant currency, currencies or currency units. 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
Conversion Event has occurred with respect to a Foreign Currency, the Company
will promptly give written notice thereof to the Trustee (or any applicable
Paying Agent) and to the Exchange Rate Agent (and the Trustee (or such Paying
Agent) will promptly thereafter give notice in the manner provided in Section
1.6 to the affected Holders) specifying the Conversion Date. In the event the
Company so determines that a Conversion Event has occurred with respect to any
currency unit in which Securities are denominated or payable, the Company will
promptly give written notice thereof to the Trustee (or any applicable Paying
Agent) and to the Exchange Rate Agent (and the Trustee (or such Paying Agent)
will promptly thereafter give notice in the manner provided in Section 1.6 to
the affected Holders) specifying the Conversion Date and the Specified Amount of
each Component Currency on the Conversion Date. In the event the Company
determines in good faith that any subsequent change in any Component Currency as
set forth in the definition of Specified Amount above has occurred, the Company
will similarly give written notice to the Trustee (or any applicable Paying
Agent) and to the Exchange Rate Agent.

                   The Trustee of the appropriate series of Securities 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 3.12. Appointment and Resignation of Exchange Rate
Agent. (a) Unless otherwise specified pursuant to Section 3.1, if and so long as
the Securities of any series (i) are denominated in a currency or currency unit
other than Dollars or (ii) may be payable in a currency or currency unit 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 3.11
for the purpose of determining the applicable rate of exchange and, if
applicable, for the purpose of converting the issued currency or currencies or
currency unit or units into the applicable payment currency or currency unit for
the payment of principal, premium, if any, and interest, if any, pursuant to
Section 3.11.

                   (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 of the appropriate series of Securities accepting such appointment
executed by the successor Exchange Rate Agent.

                  (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

                                       37

<PAGE>

the Securities of one or more series, the Company 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 3.1, 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 or currencies or currency unit or units).

                  Section 3.13. CUSIP Numbers. The Company in issuing Securities
may use "CUSIP" numbers (if then generally in use), and if so, the Trustee may
use the CUSIP numbers in notices of redemption or exchange as a convenience to
Holders; provided, however, that any such notice may state that no
representation is made as to the correctness or accuracy of the CUSIP number
printed in the notice or on the Securities, that reliance may be placed only on
the other identification numbers printed on the Securities, and any such
redemption or exchange shall not be affected by any defect or omission of such
CUSIP numbers. The Company will promptly notify the Trustee of any change in
CUSIP numbers known to an Officer of the Company.

                  exchange for Registered Securities and maturing after such
                  exchange, surrender of which is not required or has been
                  waived as provided in Section 3.5, (ii) such Securities and

                  such coupons appertaining to Bearer Securities called for
                  redemption and maturing after the relevant Redemption Date,
                  surrender of which has been waived as provided in Section 10.6
                  and (iv) such Securities and coupons for whose payment money
                  has theretofore been deposited in trust or

                   repaid to the Company or discharged from such trust, as
                   provided in Section 9.3) have been delivered to the Trustee
                   for cancellation; or

                           (B) all Securities of such series and, in the case of

                   theretofore delivered to the Trustee for cancellation

                                one year under arrangements satisfactory to the
                                Trustee for giving of notice of redemption by
                                the Trustee in the name, and at the expense, of
                                the Company,

                   and the Company, in the case of (i), (ii) or (iii) above, has
                   irrevocably deposited or caused to be deposited with the
                   Trustee as trust funds in trust for the purpose an amount in
                   the currency or currencies or currency unit or units in which
                   the Securities of such series are payable, sufficient to pay
                   and discharge the entire indebtedness on such Securities and
                   such coupons not theretofore delivered to the Trustee for
                   cancellation, for principal, premium, if any, and interest,
                   with respect thereto, to the date of such deposit (in the
                   case of Securities which have become due and payable) or to
                   the Stated Maturity or Redemption Date, as the case may be;

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

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

Notwithstanding the satisfaction and discharge of this Indenture, the obligation
of the Company to the Trustee and any predecessor Trustee under Section 6.8, the
obligations of the Company to any Authenticating Agent under Section 6.13 and,
if money shall have been deposited with the Trustee pursuant to subclause (B) of
clause (1) of this Section, the obligations of the Trustee under Section 4.2 and
the last paragraph of Section 9.3 shall survive such satisfaction and discharge.

                   Section 4.2. Application of Trust Funds. Subject to the
provisions of the last paragraph of Section 9.3, all money deposited with the
Trustee pursuant to Section 4.1 shall be held in trust and

                                       39
<PAGE>

applied by it, in accordance with the provisions of the Securities, the coupons
and this Indenture, to the payment, either directly or through any Paying Agent
(including the Company acting as its own Paying Agent) as the Trustee may
determine, to the Persons entitled thereto, of the principal, premium, if any,
and any interest for whose payment such money has been deposited with or
received by the Trustee, but such money need not be segregated from other funds
except to the extent required by law.

                   Section 4.3. Applicability of Defeasance Provisions;
Company's Option to Effect Defeasance or Covenant Defeasance. Unless pursuant to
Section 3.1 provision is made to exclude with respect to the Securities of a
particular series either or both of (i) defeasance of the Securities of or
within such series under Section 4.4 or (ii) covenant defeasance of the
Securities of or within such series under Section 4.5, then the provisions of
such Section or Sections, as the case may be, together with the provisions of
Sections 4.6 through 4.9 inclusive, with such modifications thereto as may be
specified pursuant to Section 3.1 with respect to any Securities of such series,
shall be applicable to such Securities and any coupons appertaining thereto, and
the Company may at its option, at any time, with respect to such Securities and
any coupons appertaining thereto, elect to have Section 4.4 (if applicable) or
Section 4.5 (if applicable) be applied to such Outstanding Securities and any
coupons appertaining thereto upon compliance with the conditions set forth below
in this Article.

                   Section 4.4. Defeasance and Discharge. Upon the Company's
exercise of the option specified in Section 4.3 applicable to this Section with
respect to the Securities of or within a series, the Company shall be deemed to
have been discharged from its obligations with respect to such Securities and
any coupons appertaining thereto on the date the conditions set forth in Section
4.6 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 Securities and any coupons appertaining
thereto, which Securities and coupons appertaining thereto shall thereafter be
deemed to be "Outstanding" only for the purposes of Section 4.7 and the other
Sections of this Indenture referred to in clause (ii) of this Section, and to
have satisfied all its other obligations under such Securities and any coupons
appertaining thereto and this Indenture insofar as such Securities and any
coupons appertaining thereto are concerned (and the Trustee, at the expense of
the Company, shall on Company Order execute proper instruments acknowledging the
same), except the following which shall survive until otherwise terminated or
discharged hereunder: (i) the rights of Holders of such Securities and any
coupons appertaining thereto to receive, solely from the trust funds described
in Section 4.6(a) and as more fully set forth in such Section, payments in
respect of the principal of, premium, if any, and interest, if any, on such
Securities or any coupons appertaining thereto when such payments are due; (ii)
the Company's obligations with respect to such Securities under Sections 3.5,
3.6, 9.2 and 9.3 and with respect to the payment of additional amounts, if any,
payable with respect to such Securities as specified pursuant to Section 3.1(b)
(17); (iii) the rights, powers, trusts, duties and immunities of the Trustee
hereunder and (iv) this Article IV. Subject to compliance with this Article IV,
the Company may exercise its option under this Section notwithstanding the prior
exercise of its option under Section 4.5 with respect to such Securities and any
coupons appertaining thereto. Following a defeasance, payment of such Securities
may not be accelerated because of an Event of Default.

                                       40
<PAGE>

                   Section 4.5. Covenant Defeasance. Upon the Company's exercise
of the option specified in Section 4.3 applicable to this Section with respect
to any Securities of or within a series, the Company shall be released from its
obligations under Sections 7.1, 9.4 and 9.5, and, if specified pursuant to
Section 3.1, its obligations under any other covenant, with respect to such
Securities and any coupons appertaining thereto on and after the date the
conditions set forth in Section 4.6 are satisfied (hereinafter, "covenant
defeasance"), and such Securities and any coupons appertaining thereto shall
thereafter be deemed to be not "Outstanding" for the purposes of any direction,
waiver, consent or declaration or Act of Holders (and the consequences of any
thereof) in connection with Sections 7.1, 9.4 and 9.5, or such other covenant,
but shall continue to be deemed "Outstanding" for all other purposes hereunder.
For this purpose, such covenant defeasance means that, with respect to such
Securities and any coupons appertaining thereto, the Company may omit to comply
with and shall have no liability in respect of any term, condition or limitation
set forth in any such Section or such other covenant, whether directly or
indirectly, by reason of any reference elsewhere herein to any such Section or
such other covenant or by reason of reference in any such Section or such other
covenant to any other provision herein or in any other document and such
omission to comply shall not constitute a Default or an Event of Default under
Section 5.1(3) or 5.1(6) or otherwise, as the case may be, but, except as
specified above, the remainder of this Indenture and such Securities and any
coupons appertaining thereto shall be unaffected thereby.

                   Section 4.6. Conditions to Defeasance or Covenant
Defeasance. The following shall be the conditions to application of Section 4.4
or Section 4.5 to any Securities of or within a series and any coupons

         through 4.9 inclusive and the last paragraph of Section 9.3 applicable
         to the Trustee, for purposes of such Sections also a "Trustee") as

         in clauses (x) and (y) of this Section 4.6(a), specifically pledged as
         security for, and dedicated solely to, the benefit of the Holders of
         such Securities and any coupons appertaining thereto, with instructions
         to the Trustee as to the application thereof, (A) money in an amount
         (in such currency, currencies or currency unit or units in which such
         Securities and any coupons appertaining thereto are then specified as
         payable at Maturity), or (B) if Securities of such series are not
         subject to repayment at the option of Holders, Government Obligations
         which through the payment of interest and principal in respect thereof
         in accordance with their terms will provide, not later than one day
         before the due date of any payment referred to in clause (x) or (y) of
         this Section 4.6(a), money in an amount or (C) a combination thereof in
         an amount, sufficient, in the opinion of a nationally recognized
         independent accounting or investment banking firm expressed in a
         written certification thereof delivered to the Trustee, to pay and
         discharge, and which shall be applied by the Trustee to pay and
         discharge, (x) the principal of, premium, if any, and interest, if any,
         on such Securities and any coupons appertaining thereto on the Maturity
         of such principal or installment of principal or interest and (y) any
         mandatory sinking fund payments applicable to such Securities on the
         day

                                       41

<PAGE>

         on which such payments are due and payable in accordance with the terms
         of this Indenture and such Securities and any coupons appertaining
         thereto. Before such a deposit the Company may make arrangements
         satisfactory to the Trustee for the redemption of Securities at a
         future date or dates in accordance with Article X which shall be given
         effect in applying the foregoing.

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

                  (c) In the case of an election under Section 4.4, no Default
         or Event of Default under Section 5.1(4) or 5.1(5) with respect to such
         Securities and any coupons appertaining thereto shall have occurred and
         be continuing during the period commencing on the date of such deposit
         and ending on the 91st day after such date (it being understood that
         this condition shall not be deemed satisfied until the expiration of
         such period).

                  (d) In the case of an election under Section 4.4, the Company
         shall have delivered to the Trustee an Officers' Certificate and an
         Opinion of Counsel to the effect that (i) the Company has received
         from, or there has been published by, the Internal Revenue Service a
         ruling, or (ii) since the date of execution of this Indenture, there
         has been a change in the applicable Federal income tax law, in either
         case to the effect that, and based thereon such opinion shall confirm
         that, the Holders of such Securities and any coupons appertaining
         thereto will not recognize income, gain or loss for Federal income tax
         purposes as a result of such defeasance and will be subject to Federal
         income tax on the same amounts and in the same manner and at the same
         times, as would have been the case if such deposit, defeasance and
         discharge had not occurred.

                  (e) In the case of an election under Section 4.5, the Company
         shall have delivered to the Trustee an Opinion of Counsel to the effect
         that the Holders of such Securities and any coupons appertaining
         thereto will not recognize income, gain or loss for Federal income tax
         purposes as a result of such covenant defeasance and will be subject to
         Federal income tax on the same amounts, in the same manner and at the
         same times as would have been the case if such covenant defeasance had
         not occurred.

                  (f) The Company shall have delivered to the Trustee an
         Officers' Certificate and an Opinion of Counsel, each stating that all
         conditions precedent to the defeasance under Section 4.4 or the
         covenant defeasance under Section 4.5 (as the case may be) have been
         complied with and an Opinion of Counsel to the effect that either (i)
         as a result of a deposit pursuant to subsection (a) above and the
         related exercise of the Company's option under Section 4.4 or Section
         4.5 (as the case may be), registration is not required under the
         Investment Company Act of 1940, as amended, by the Company, with
         respect to the trust funds representing such deposit or by the trustee
         for such trust funds or (ii) all necessary registrations under said act
         have been effected.

                   (g) Such defeasance or covenant defeasance shall be effected
          in compliance with any additional or substitute terms, conditions or
          limitations which may be imposed on the Company in connection
          therewith as contemplated by Section 3.1.

                   Section 4.7. Deposited Money and Government Obligations to Be
Held in Trust. Subject to the provisions of the last paragraph of Section 9.3,
all money and Government Obligations (or other property as may be provided
pursuant to Section 3.1) (including the proceeds thereof) deposited with the
Trustee pursuant to Section 4.6 in respect of any Securities of any series and
any coupons appertaining thereto shall be held in trust and applied by the
Trustee, in accordance with the provisions of such Securities and any coupons
appertaining thereto and this Indenture, to the payment, either directly or
through any Paying Agent (including the Company acting as its own Paying Agent)
as the Trustee may determine, to the Holders of such Securities and any coupons
appertaining thereto of all sums due and to become due thereon in respect of
principal, premium, if any, and interest, if any, but such money need not be
segregated from other funds except to the extent required by law.

                   Unless otherwise specified with respect to any Security
pursuant to Section 3.1, if, after a deposit referred to in Section 4.6(a) has
been made, (i) the Holder of a Security in respect of which such deposit was
made is entitled to, and does, elect pursuant to Section 3.11(b) or the terms of
such Security to receive payment in a currency or currency unit other than that
in which the deposit pursuant to Section 4.6(a) has been made in respect of such
Security, or (ii) a Conversion Event occurs as contemplated in Section 3.11(d)
or 3.11(e) or by the terms of any Security in respect of which the deposit
pursuant to Section 4.6(a) has been made, the indebtedness represented by such
Security and any coupons appertaining thereto shall be deemed to have been, and
will be, fully discharged and satisfied through the payment of the principal of,
premium, if any, and interest, if any, on such Security as the same becomes due
out of the proceeds yielded by converting (from time to time as specified below
in the case of any such election) the amount or other property deposited in
respect of such Security into the currency or currency unit 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 or currency unit in
effect on the second Business Day prior to each payment date, except, with
respect to a Conversion Event, for such currency or currency unit in effect (as
nearly as feasible) at the time of the Conversion Event.

                   Section 4.8. Repayment to Company. The Trustee (and any
Paying Agent) shall promptly pay to the Company upon Company Request any excess
money or securities held by them at any time.

                   Section 4.9. Indemnity for Government Obligations. The
Company shall pay, and shall indemnify the Trustee against, any tax, fee or
other charge imposed on or assessed against Government Obligations deposited
pursuant to this Article or the principal and interest received on such
Government Obligations, other than any such tax, fee or other charge that by law
is for the account of the Holders of the Securities subject to defeasance or
covenant defeasance pursuant to this Article.

                              DEFAULTS AND REMEDIES

                   Section 5.1. Events of Default. An "Event of Default" occurs
with respect to the Securities of any series if (whatever the reason for such
Event of Default and whether it shall be voluntary or involuntary or be effected
by operation of law or pursuant to any judgment, decree or order of any court or
any order, rule or regulation of any administrative or governmental body):

                   (1) the Company defaults in the payment of interest on any
         Security of that series or any coupon appertaining thereto or any
         additional amount payable with respect to any Security of that series
         as specified pursuant to Section 3.1(b) (17) when the same becomes due
         and payable and such default continues for a period of 30 days;

                   (2) the Company defaults in the payment of the principal of
         or any premium on any Security of that series when the same becomes due
         and payable at its Maturity or on redemption or otherwise, or in the

         terms of the Securities of that series, and in each case such default
         continues for a period of ten days;

                   (3) the Company defaults in the performance of, or breaches,
         any covenant or warranty of the Company in this Indenture with respect
         to any Security of that series (other than a covenant or warranty a
         default in whose performance or whose breach is elsewhere in this
         Section specifically dealt with) and such default or breach continues
         for a period of 60 days after there has been given, by registered or
         certified mail, to the Company by the Trustee or to the Company and the
         Trustee by the Holders of at least 25% in principal amount of the
         Outstanding Securities of that series, a written notice specifying such
         default or breach and requiring it to be remedied and stating that such
         notice is a "Notice of Default" hereunder;

                   (4) the Company pursuant to or within the meaning of any
         Bankruptcy Law (A) commences a voluntary case, (B) consents to the
         entry of an order for relief against it in an involuntary case, (C)
         consents to the appointment of a Custodian of it or for all or
         substantially all of its property, or (D) makes a general assignment
         for the benefit of its creditors;

                   (5) a court of competent jurisdiction enters an order or
         decree under any Bankruptcy Law that (A) is for relief against the
         Company in an involuntary case, (B) appoints a Custodian of the Company
         or for all or substantially all of its property, or (C) orders the
         liquidation of the Company; and the order or decree remains unstayed
         and in effect for 90 days; or

                   (6) there occurs any other Event of Default provided as
         contemplated by Section 3.1 with respect to Securities of that series.

                   The term "Bankruptcy Law" means Title 11, U.S. Code, or any
similar federal or state law for the relief of debtors. The term "Custodian"
means any receiver, trustee, assignee, liquidator or similar official under any
Bankruptcy Law.

                   Section 5.2. Acceleration; Rescission and Annulment. If an
Event of Default with respect to the Securities of any series at the time
Outstanding occurs and is continuing, the Trustee or the Holders of at least 25%
in aggregate principal amount of all of the Outstanding Securities of that
series, by written notice to the Company (and, if given by the Holders, to the
Trustee), may declare the principal (or, if the Securities of that series are
Original Issue Discount Securities or Indexed Securities, such portion of the
principal amount or other amount as may be specified in the terms of that
series) of all the Securities of that series to be due and payable and upon any
such declaration such principal (or, in the case of Original Issue Discount
Securities or Indexed Securities, such specified amount) shall be immediately
due and payable.

                   At any time after such a declaration of acceleration with
respect to Securities of any series has been made and before a judgement 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 aggregate
principal amount of the Outstanding Securities of that series, by written notice
to the Trustee, may rescind and annul such declaration and its consequences if
all existing Defaults and Events of Default with respect to Securities of that
series, other than the non-payment of the principal of Securities of that series
which has become due solely by such declaration of acceleration, have been cured
or waived as provided in Section 5.7. No such rescission shall affect any
subsequent default or impair any right consequent thereon.

                   Section 5.3. Collection of Indebtedness and Suits for
Enforcement by Trustee.  The Company covenants that if

                   (1) default is made in the payment of any interest on any
         Security or coupon, if any, 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 and such
         default continues for a period of 10 days,

the Company will, upon demand of the Trustee, pay to it, for the benefit of the
Holders of such Securities or coupons, if any, the whole amount then due and
payable on such Securities for principal, premium, if any, and interest and, to
the extent that payment of such interest shall be legally enforceable, interest
on any overdue principal, premium, if any, and on any overdue interest, at the
rate or rates prescribed therefor in such Securities or coupons, if any, 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.

                                       45
<PAGE>

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

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

                   Section 5.4. Trustee May File Proofs of Claim. The Trustee
may file such proofs of claim and other papers or documents as may be necessary
or advisable in order to have the claims of the Trustee and the Holders of
Securities allowed in any judicial proceedings relating to the Company, its
creditors or its property.

                  Section 5.5. Trustee May Enforce Claims Without Possession of
Securities. All rights of action and claims under this Indenture or the
Securities may be prosecuted and enforced by the Trustee, in its own name and as
trustee of an express trust, without the possession of any of the Securities or
the production thereof in any proceeding relating thereto.

                  Section 5.6. Delay or Omission Not Waiver. No delay or
omission by the Trustee or any Holder of any Securities to exercise any right or
remedy accruing upon an Event of Default shall impair any such right or remedy
or constitute a waiver of or acquiescence in any such Event of Default.

                  Section 5.7. Waiver of Past Defaults. The Holders of a
majority in aggregate principal amount of Outstanding Securities of any series
by notice to the Trustee may waive on behalf of the Holders of all Securities of
such series a past Default or Event of Default with respect to that series and
its consequences except a Default or Event of Default (i) in the payment of the
principal of, premium, if any, or interest, if any, on any Security of such
series or any coupon appertaining thereto or (ii) in respect of a covenant or
provision hereof which pursuant to Section 8.2 cannot be amended or modified
without the consent of the Holder of each Outstanding Security of such series
adversely affected. Upon any such waiver, such Default shall cease to exist, and
any Event of Default arising therefrom shall be deemed to have been cured, for
every purpose of this Indenture; but no such waiver shall extend to any
subsequent or other Default or Event of Default or impair any right consequent
thereon. In case of any such waiver, the Company, the Trustee and the Holders
shall be restored to their former positions and rights hereunder and under the
Securities of such series, respectively.

<PAGE>

                  Section 5.8. Control by Majority. The Holders of a majority in
aggregate principal amount of the Outstanding Securities of each series affected
(with each such series voting as a class) shall have the right to direct the
time, method and place of conducting any proceeding for any remedy available to
the Trustee or exercising any trust or power conferred on it with respect to
Securities of that series; provided, however, that (i) the Trustee may refuse to
follow any direction that conflicts with law or this Indenture, (ii) the Trustee
may refuse to follow any direction that is unduly prejudicial to the rights of
the Holders of Securities of such series not consenting, or that would in the
good faith judgment of the Trustee have a substantial likelihood of involving
the Trustee in personal liability and (iii) the Trustee may take any other
action deemed proper by the Trustee which is not inconsistent with such
direction.

                  Section 5.9. Limitation on Suits by Holders. No Holder of any
Security of any series or any coupons appertaining thereto shall have any right
to institute any proceeding, judicial or otherwise, with respect to this
Indenture, or for the appointment of a receiver or trustee, or for any other
remedy hereunder, unless:

                  (1)   the 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 at least 25% in aggregate principal
         amount of the Outstanding Securities of that series have made a written
         request to the Trustee to institute proceedings in respect of such
         Event of Default in its own name as Trustee hereunder;

                  (3)   such Holder or Holders have offered to the Trustee
         indemnity satisfactory to the Trustee against any loss, liability or
         expense to be, or which may be, incurred by the Trustee in pursuing the
         remedy;

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

                  (5)   during such 60 day period, the Holders of a majority in
         aggregate principal amount of the Outstanding Securities of that series
         have not given to the Trustee a direction inconsistent with such
         written request.

         No one or more 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 of such Holders, or to obtain or to seek to
obtain priority or preference over any other of such Holders or to enforce any
right under this Indenture, except in the manner herein provided and for the
equal and ratable benefit of all of such Holders.

                  Section 5.10. Rights of Holders to Receive Payment.
Notwithstanding any other provision of this Indenture, but subject to Section
8.2, the right of any Holder of a Security or coupon to receive payment of
principal of, premium, if any, and, subject to Sections 3.5 and 3.7, interest on
the

                                       47
<PAGE>

Security, on or after the respective due dates expressed in the Security
(or, in case of redemption, on the redemption dates), and the right of any
Holder of a coupon to receive payment of interest due as provided in such
coupon, or to bring suit for the enforcement of any such payment on or after
such respective dates, shall not be impaired or affected without the consent of
such Holder.

                  Section 5.11. Application of Money Collected. If the Trustee
collects any money pursuant to this Article, it shall pay out the money 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, premium, if any, or
interest, upon presentation of the Securities and the notation thereon of the
payment if only partially paid and upon surrender thereof if fully paid:

                  First:   to the Trustee for amounts due under Section 6.8;

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

                  Third:   to the Company.

The Trustee may fix a record date and payment date for any payment to Holders
pursuant to this Section 5.11. At least 15 days before such record date, the
Trustee shall mail to each Holder and the Company a notice that states the
record date, the payment date and the amount to be paid.

                  Section 5.12. 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 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.

                  Section 5.13. Rights and Remedies Cumulative. Except as
otherwise provided with respect to the replacement or payment of mutilated,
destroyed, lost or stolen Securities in the last paragraph of Section 3.6, no
right or remedy herein conferred upon or reserved to the Trustee or the Holders
is intended to be exclusive of any other right or remedy, and every right and
remedy shall, to the extent permitted by law, be cumulative and in addition to
every other right and remedy given hereunder or now or hereafter existing at law
or in equity or otherwise. The assertion or employment of any right or remedy
hereunder, or otherwise, shall not prevent the concurrent assertion or
employment of any other appropriate right or remedy.

                  Section 5.14. Waiver of Stay, Extension or Usury Laws. The
Company covenants (to the extent that it may lawfully do so) that it will not at
any time insist upon, or plead, or in any manner whatsoever claim or take the
benefit or advantage of, any stay or extension law or any usury or other similar
law wherever enacted, now or at any time hereafter in force, that would prohibit
or forgive the Company from paying all or any portion of the principal of (or
premium, if any) or interest on the Securities contemplated herein or in the
Securities or that may affect the covenants or the performance of this
Indenture; and the Company (to the extent that it may lawfully do so) hereby
expressly waives all benefit or advantage of any such law, and covenants that it
will not hinder, delay or impede the execution of any power herein granted to
the Trustee, but will suffer and permit the execution of every such power as
though no such law had been enacted.

                                   ARTICLE VI

                                   THE TRUSTEE

                  Section 6.1. Rights of Trustee. Subject to the provisions of
the Trust Indenture Act:

                  (a) The Trustee may conclusively rely and shall be protected
         in acting or refraining from acting upon any document believed by it to
         be genuine and to have been signed or presented by the proper party or
         parties. The Trustee need not investigate any fact or matter stated in
         the document.

                  (b) Any request or direction of the Company mentioned herein
         shall be sufficiently evidenced by a Company Request or Company Order
         (other than delivery of any Security, together with any coupons
         appertaining thereto, to the Trustee for authentication and delivery
         pursuant to Section 3.3, which shall be sufficiently evidenced as
         provided therein) and any resolution of the Board of Directors may be
         sufficiently evidenced by a Board Resolution.

                  (c) Before the Trustee acts or refrains from acting, it may
         consult with counsel of its own selection or require an Officers'
         Certificate. The Trustee shall not be liable for any action it takes or
         omits to take in good faith in reliance on a Board Resolution, the
         advice of counsel, a certificate of an Officer or Officers delivered
         pursuant to Section 1.2, an Officers' Certificate or an Opinion of
         Counsel.

                  (d) The Trustee may act through agents or attorneys and shall
         not be responsible for the misconduct or negligence of any agent or
         attorney appointed with due care.

                  (e) The Trustee shall not be liable for any action it takes or
         omits to take in good faith which it believes to be authorized or
         within its discretion or rights or powers.

                                       49
<PAGE>

                  (f) Unless otherwise expressly provided in this Indenture, the
         Trustee shall have no obligation to distribute to the Holders, the
         Company or any third party any amounts to be paid to the Trustee until
         such amounts are collected by the Trustee.

                  (g) The rights, privileges, protections, immunities and
         benefits given to the Trustee, including, without limitation, its right
         to be indemnified, are extended to, and shall be enforceable by, the
         Trustee in each of its capacities hereunder.

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

         Notwithstanding anything contained herein to the contrary, in case an
Event of Default with respect to the Securities of any series has occurred and
is continuing, the Trustee shall exercise, with respect to Securities of such
series, such of the rights and powers vested in it by this Indenture, and shall
use the same degree of care and skill in their exercise, as a prudent individual
would exercise or use under the circumstances in the conduct of his or her own
affairs.

                   Section 6.2. Trustee May Hold Securities. The Trustee, any
Paying Agent, any Registrar or any other agent of the Company, in its individual
or any other capacity, may become the owner or pledgee of Securities and coupons
and, subject to Sections 310(b) and 311 of the Trust Indenture Act, may
otherwise deal with the Company, the Parent, an Affiliate or Subsidiary with the
same rights it would have if it were not Trustee, Paying Agent, Registrar or
such other agent.

                   Section 6.3. 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 6.4. Trustee's Disclaimer. The recitals contained
herein and in the Securities, except the Trustee's certificate of
authentication, shall be taken as the statements of the Company, and the Trustee
assumes no responsibility for their correctness. The Trustee makes no
representation as to the validity or adequacy of this Indenture or the
Securities or any coupon, except that the Trustee represents and warrants that
it is duly authorized to execute and deliver this Indenture, authenticate the
Securities and perform its obligations hereunder and thereunder; that the
statements made by it in a Statement of Eligibility on Form T-1 supplied or to
be supplied to the Company in connection with the registration of any Securities
are and will be true and accurate subject to the qualifications set forth
therein; and that such Statement complies and will comply in all material
respects with the requirements of the Trust Indenture Act and the Securities
Act. The Trustee shall not be accountable for the Company's use of the proceeds
from the Securities or for monies paid over to the Company pursuant to the
Indenture.

                   Section 6.5. Notice of Defaults. If a Default occurs and is
continuing with respect to the Securities of any series and if it is actually
known to a Responsible Officer of the Trustee, the Trustee shall, within 90 days
after it occurs, transmit, in the manner and to the extent provided in Section
313(c) of the Trust Indenture Act, notice of all uncured Defaults known to it;
provided, however, that, except in the case of a Default in payment on the
Securities of any series, the Trustee may withhold the notice if and so long as
a Responsible Officer in good faith determines that withholding such notice is
in the interests of Holders of Securities of that series; provided, further,
that in the case of any default or breach of the character specified in Section
5.1(3) with respect to the Securities and coupons of such series, no such notice
to Holders shall be given until at least 60 days after the occurrence thereof.
The Trustee shall not be deemed to have notice of any Default or Event of
Default unless a Responsible Officer of the Trustee has actual knowledge thereof
or unless written notice of any event which is in fact such a Default is
received by the Trustee at the Corporate Trust Office of the Trustee.

                   Section 6.6. Reports by Trustee to Holders. Within 60 days
after each May 15 of each year commencing with the first May 15 after the first
issuance of Securities pursuant to this Indenture, the Trustee shall transmit by
mail to all Holders of Securities as provided in Section 313(c) of the Trust
Indenture Act a brief report dated as of such May 15 if required by and in
compliance with Section 313(a) of the Trust Indenture Act. A copy of each report
shall, at the time of such transmission to Holders, be filed by the Trustee with
each stock exchange, if any, upon which the Securities are listed, with the
Commission and with the Company. The Company will promptly notify the Trustee
when the Securities are listed on any stock exchange and of any delisting
thereof.

                   Section 6.7. Security Holder Lists. The Trustee shall
preserve in as current a form as is reasonably practicable the most recent list
available to it of the names and addresses of Holders of Securities of each
series. If the Trustee is not the Registrar, the Company shall furnish to the
Trustee semiannually on or before the last day of June and December in each
year, and at such other times as the Trustee may request in writing, a list, in
such form and as of such date as the Trustee may reasonably require, containing
all the information in the possession or control of the Registrar, the Company
or any of its Paying Agents other than the Trustee as to the names and addresses
of Holders of Securities of each such series. If there are Bearer Securities of
any series Outstanding, even if the Trustee is the Registrar, the Company shall
furnish to the Trustee such a list containing such information with respect to
Holders of such Bearer Securities only.

                   Section 6.8. Compensation and Indemnity. (a) The Company
shall pay to the Trustee from time to time such compensation for its services as
the Company and the Trustee may agree in writing from time to time. The
Trustee's compensation shall not be limited by any law on compensation of a
trustee of an express trust. The Company shall reimburse the Trustee upon
request for all reasonable expenses, disbursements and advances incurred by it
in connection with the performance of its duties under this Indenture, except
any such expense, disbursement or advance as shall be determined to have been
caused by its own negligence or willful misconduct. Such expenses shall include
the reasonable compensation and expenses of the Trustee's agents and counsel.

                                       51
<PAGE>

                  (b) The Company shall indemnify the Trustee for, and hold it
harmless against, any and all loss, liability, damage, claim or expense
(including taxes other than taxes based upon, measured by or determined by the
income of the Trustee), including the costs and expenses of defending itself
against any third-party claim (whether asserted by any Holder or any other
Person (other than the Company)), incurred by it arising out of or in connection
with its acceptance or administration of the trust or trusts hereunder
(collectively, "Claims"). The Trustee shall notify the Company promptly of any
Claim for which it may seek indemnity. The Company shall defend the Claim and
the Trustee shall cooperate in the defense. The Trustee may have separate
counsel and the Company shall pay the reasonable fees and expenses of such
counsel. The Company need not pay for any settlement made without its consent.

                  (c) The Company need not reimburse any expense, disbursement
or advance or indemnify against any Claim incurred by the Trustee through
negligence or bad faith.

                  (d) To secure the payment obligations of the Company pursuant
to this Section, the Trustee shall have a lien prior to the Securities of any
series on all money or property held or collected by the Trustee, except that
held in trust to pay principal, premium, if any, and interest on particular
Securities.

                  (e) When the Trustee incurs expenses or renders services in
connection with an Event of Default specified in Section 5.1(4) or Section
5.1(5), the expenses (including the reasonable charges and expenses of its
counsel) and the compensation for the services are intended to constitute
expenses of administration under any applicable federal or state bankruptcy,
insolvency or other similar law.

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

                   Section 6.9. Replacement of Trustee. (a) The resignation
or removal of the Trustee and the appointment of a successor Trustee shall
become effective only upon the successor Trustee's acceptance of appointment as
provided in Section 6.10.

                   (b) The Trustee may resign at any time with respect to the
Securities of any series by giving written notice thereof to the Company. If the
instrument of acceptance by a successor Trustee required by Section 6.10 shall
not have been delivered to the Trustee within 30 days after the giving of such
notice of resignation, the resigning Trustee may petition, at the expense of the
Company, any court of competent jurisdiction for the appointment of a successor
Trustee with respect to the Securities of such series.

                   (c) The Holders of a majority in aggregate principal amount
of the Outstanding Securities of any series may remove the Trustee with respect
to that series by so notifying the Trustee and the Company and may appoint a
successor Trustee for such series with the Company's consent. If an instrument
of acceptance by a successor Trustee required by Section 6.10 shall not have
been delivered to the Trustee within 30 days after the giving of such notice of
removal, the Trustee being

                                       52
<PAGE>

removed may petition, at the expense of the Company, any court of competent
jurisdiction for the appointment of a successor Trustee with respect to the
Securities of such series.

                   (d) If at any time:

                   (1) the Trustee fails to comply with Section 310(b) of the
         Trust Indenture Act 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 6.11
         hereof or Section 310(a) of the Trust Indenture Act and shall fail to
         resign after written request therefor by the Company or by any Holder
         of a Security who has been a bona fide Holder of a Security for at
         least six months; or

                   (3) the Trustee becomes incapable of acting, is adjudged a
         bankrupt or an insolvent or a receiver or public officer takes charge
         of the Trustee or its property or affairs for the purpose of
         rehabilitation, conservation or liquidation,

then, in any such case, (i) the Company may remove the Trustee with respect to
all Securities, or (ii) subject to Section 315(e) of the Trust Indenture Act,
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 resigns or is removed or becomes incapable
of acting or if a vacancy exists in the office of Trustee for any reason, with
respect to Securities of one or more series, the Company shall promptly appoint
a successor Trustee 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) and shall comply with the applicable requirements of Section 6.10. If,
within one year after such resignation, removal or incapability, or the
occurrence of such vacancy, a successor Trustee with respect to the Securities
of any series shall be appointed by Act of the Holders of a majority in
principal amount of the Outstanding Securities of such series delivered to the
Company and the retiring Trustee, the successor Trustee so appointed shall,
forthwith upon its acceptance of such appointment in accordance with the
applicable requirements of Section 6.10, 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 required by Section 6.10,
then, subject to Section 315(e) of the Trust Indenture Act, 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.

                  Section 6.10. 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 shall execute, acknowledge and deliver
to the Company and to the retiring Trustee an instrument accepting such
appointment. Thereupon, the resignation or removal of the retiring Trustee shall
become effective, and the successor Trustee, without further act, deed or
conveyance, shall become vested with all the rights, powers 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 such successor Trustee shall execute and
deliver an indenture supplemental hereto wherein such successor Trustee shall
accept such appointment and which (i) shall contain such provisions as shall be
necessary or desirable to transfer and confirm to, and to vest in, such
successor Trustee all the rights, powers, trusts and duties of the retiring
Trustee with respect to the Securities of that or those series to which the
appointment of such successor Trustee relates, (ii) if the retiring Trustee is
not retiring with respect to all Securities, shall contain such provisions as
shall be deemed necessary or desirable to confirm that all the rights, powers,
trusts and duties of the retiring Trustee with respect to the Securities of that
or those series as to which the retiring Trustee is not retiring shall continue
to be vested in the retiring Trustee, and (iii) shall add to or change any of
the provisions of this Indenture as shall be necessary to provide for or
facilitate the administration of the trusts hereunder by more than one Trustee,
it being understood that nothing herein or in such supplemental indenture shall
constitute such Trustees co-trustees of the same trust and that each such
Trustee shall be trustee of a trust or trusts hereunder separate and apart from
any trust or trusts hereunder administered by any other such Trustee and upon
the execution and delivery of such supplemental indenture the resignation or
removal of the retiring Trustee shall become effective to the extent provided
therein and each such successor Trustee, without any further act, deed or
conveyance, shall become vested with all the rights, powers, trusts and duties
of the retiring Trustee with respect to the Securities of that or those series
to which the appointment of such successor Trustee relates; but, on request of
the Company or any successor Trustee, such retiring Trustee shall duly assign,
transfer and deliver to such successor Trustee all property and money held by
such retiring Trustee hereunder with respect to the Securities of that or those
series to which the appointment of such successor Trustee relates.

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

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

                                       54
<PAGE>

                   (e) 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 in the manner provided for notices to the Holders of Securities in
Section 1.6. 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 6.11. Eligibility; Disqualification. There shall at
all times be a Trustee hereunder with respect to each series of Securities
(which need not be the same Trustee for all series). Each Trustee hereunder
shall be eligible to act as trustee under Section 310(a) (1) of the Trust
Indenture Act and shall have a combined capital and surplus of at least
$50,000,000. If such corporation publishes reports of condition at least
annually, pursuant to law or 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 specified in this Article.

                   If the Trustee has or shall acquire a conflicting interest
within the meaning of the Trust Indenture Act, the Trustee shall either
eliminate such interest or resign, to the extent and in the manner provided by,
and subject to the provisions of, the Trust Indenture Act and this Indenture. To
the extent permitted by the Trust Indenture Act, any Trustee hereunder shall not
be deemed to have a conflicting interest by virtue of being the trustee under
the Indenture dated May 1, 1986 between the Parent and Commerce Union Bank, the
Indenture dated March 1, 1991 between the Company and Citibank, N.A., Trustee,
the Indenture dated March 1, 1992 between the Parent and Morgan Guaranty Trust
Company of New York or the Indenture dated December 1, 1998 between the Parent
and Citibank, N.A., Trustee and with respect to any or all series of securities
issued or issuable under such indentures, or, with respect to any series of
Securities, by virtue of being the Trustee with respect to any other series of
Securities.

                   Section 6.12. Merger, Conversion, Consolidation or Succession
to Business. Any corporation into which the Trustee may be merged or converted
or with which it may be consolidated, or any corporation resulting from any
merger, conversion or consolidation to which the Trustee shall be a party, or
any corporation succeeding to all or substantially all 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.

                   Section 6.13. Appointment of Authenticating Agent. The
Trustee may appoint an Authenticating Agent or Agents with respect to one or
more series of Securities which shall be authorized

                                       55
<PAGE>

to act on behalf of the Trustee to authenticate Securities of such series issued
upon original issue exchange, registration of transfer or partial redemption
thereof, and Securities so authenticated shall be entitled to the benefits of
this Indenture and shall be valid and obligatory for all purposes as if
authenticated by the Trustee hereunder. Any such appointment shall be evidenced
by an instrument in writing signed by a Responsible Officer of the Trustee, a
copy of which 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, except as may
otherwise be provided pursuant to Section 3.1, shall at all times be a bank or
trust company or corporation organized and doing business and in good standing
under the laws of the United States of America or of any State or the District
of Columbia, authorized under such laws to act as Authenticating Agent, having a
combined capital and surplus of not less than $1,500,000 and subject to
supervision or examination by Federal or State authorities. If such
Authenticating Agent publishes reports of condition at least annually, pursuant
to law or the requirements of the aforesaid supervising or examining authority,
then for the purposes of this Section, the combined capital and surplus of such
Authenticating Agent shall be deemed to be its combined capital and surplus as
set forth in its most recent report of condition so published. In case at any
time an Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, such Authenticating Agent shall resign immediately
in the manner and with the effect specified in this Section.

                   Any corporation into which an Authenticating Agent may be
merged or converted or with which it may be consolidated, or any corporation
resulting from any merger, conversion or consolidation to which such
Authenticating Agent shall be a party, or any corporation succeeding to the
corporate agency or corporate trust business of an Authenticating Agent, shall
continue to be an Authenticating Agent, provided such corporation shall be
otherwise eligible under this Section, without the execution or filing of any
paper or further act on the part of the Trustee or the Authenticating Agent.

                   An Authenticating Agent for any series of Securities may at
any time resign by giving written notice of resignation to the Trustee for such
series and to the Company. The Trustee for any series of Securities may at any
time terminate the agency of an Authenticating Agent by giving written notice of
termination to such Authenticating Agent and to the Company. Upon receiving such
a notice of resignation or upon such a termination, or in case at any time such
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, the Trustee for such series may appoint a successor
Authenticating Agent which shall be acceptable to the Company and shall give
notice of such appointment to all Holders of Securities of the series with
respect to which such Authenticating Agent will serve in the manner set forth in
Section 1.6. Any successor Authenticating Agent upon acceptance of its
appointment hereunder shall become vested with all the rights, powers and duties
of its predecessor hereunder, with like effect as if originally named as an
Authenticating Agent herein. No successor Authenticating Agent shall be
appointed unless eligible under the provisions of this Section.

<PAGE>

                   The Company agrees to pay to each Authenticating Agent from
time to time such reasonable compensation as the Company and such Authenticating
Agent agree in writing from time to time including reimbursement of its
reasonable expenses for its services under this Section.

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

                   This is one of the Securities of the series designated herein
and issued under the within-mentioned Indenture.

                  CONSOLIDATION, MERGER OR SALE BY THE COMPANY

                  Section 7.1. Consolidation, Merger or Sale of Assets
Permitted. The Company may merge or consolidate with or into any other Person or
sell, convey, transfer or otherwise dispose of all or substantially all of its
assets to any Person, if (i) (A) in the case of a merger or consolidation, the
Company is the surviving Person or (B) in the case of a merger or consolidation
where the Company is not the surviving Person and in the case of any sale,
conveyance, transfer or other disposition, the resulting, surviving or
transferee Person is organized and existing under the laws of the United States
or a State thereof and such Person expressly assumes by supplemental indenture
all the obligations of the Company under the Securities and any coupons
appertaining thereto and under this Indenture, (ii) immediately thereafter,
giving effect to such merger or consolidation, or such sale, conveyance,
transfer or other disposition, no Default or Event of Default shall have
occurred and be continuing and (iii) the Company shall have delivered to the
Trustee an Officers' Certificate and an Opinion of Counsel each stating that
such merger, consolidation, sale, conveyance, transfer or other disposition
complies with this Article and that all conditions precedent herein provided for
relating to such transaction have been complied with. In the event of the
assumption by a successor Person of the obligations of the Company as provided
in clause (i) (B) of the immediately preceding sentence, such successor Person
shall succeed to and be substituted for

                                       57

the Company hereunder and under the Securities and any coupons appertaining
thereto and all such obligations of the Company shall terminate.

                             SUPPLEMENTAL INDENTURES

                  Section 8.1. Supplemental Indentures Without Consent of
Holders. Without the consent of any Holders, the Company and the Trustee, at any
time and from time to time, may enter into indentures supplemental hereto or, if
applicable, into agreements supplemental to any Parent Guarantee, in form
reasonably satisfactory to the Trustee, for any of the following purposes:

                   (1) to evidence the succession of another Person to the
         Company and the assumption by any such successor of the covenants and
         obligations of the Company herein and in the Securities or, if
         applicable, to evidence the succession of another Person to the Parent
         and the assumption by any such successor of the covenants of the Parent
         herein or of the Parent's obligations under any Parent Guarantee (in
         either case with such changes herein and therein as may be necessary or
         advisable to reflect such Person's legal status, if such Person is not
         a corporation); or

                   (2) to add to the covenants of the Company or the Parent for
         the benefit of the Holders of all or any series of Securities (and if
         such covenants are to be for the benefit of less than all series of
         Securities, stating that such covenants are expressly being included
         solely for the benefit of such series) or to surrender any right or
         power herein conferred upon the Company or the Parent or to comply with
         any requirement of the Commission in connection with the qualification
         of this Indenture or any Parent Guarantee under the Trust Indenture Act
         or otherwise; or

         all or any series of Securities; or

                   (4) to add to or change any of the provisions of this
         Indenture to such extent as shall be necessary to facilitate the
         issuance of Bearer Securities (including, without limitation, to
         provide that Bearer Securities may be registrable as to principal only)
         or to facilitate or provide for the issuance of Securities in global
         form in addition to or in place of Securities in certificated form; or

                   (5) to add to, or to change or eliminate, any of the
         provisions of this Indenture, including to make appropriate provisions
         for any Parent Guarantee, provided that any such change or elimination
         shall become effective only with respect to Securities which have not
         been issued as of the execution of such supplemental indenture or when
         there is no Security Outstanding of any series created prior to the
         execution of such supplemental indenture which is entitled to the
         benefit of such provision; or

         series as permitted by Sections 2.1 and 3.1; or

                   (9) to evidence and provide for the acceptance of appointment
         hereunder by a successor Trustee with respect to the Securities of one
         or more series and/or to add to or change any of the provisions of this
         Indenture as shall be necessary to provide for or facilitate the
         administration of the trusts hereunder by more than one Trustee,
         pursuant to the requirements of Article VI; or

                   (10) if allowed without penalty under applicable laws and
         regulations, to permit payment in the United States (including any of
         the states and the District of Columbia), its territories, its
         possessions and other areas subject to its jurisdiction of principal,
         premium, if any, or interest, if any, on Bearer Securities or coupons,
         if any; or

                   (11) to correct or supplement any provision herein, in any

         correct any mistake herein, in any Securities or in any Parent
         Guarantee; or

                   (12) to make any other provisions with respect to matters or
         questions arising under this Indenture, provided such action shall not
         materially adversely affect the interests of the Holders of Securities
         of any series.

                   Section 8.2. With Consent of Holders. With the written
consent of the Holders of a majority of the aggregate principal amount of the
Outstanding Securities of each series adversely affected by such supplemental
indenture (with the Securities of each series voting as a class), the Company
and the Trustee may enter into an indenture or indentures supplemental hereto to
add any provisions to or to change or eliminate any provisions of this Indenture
or of any other indenture supplemental hereto or to modify the rights of the
Holders of Securities of each such series and, if applicable, the Parent and the
Trustee may enter into an agreement or agreements supplemental hereto to add to
or to change or eliminate any provisions of a Parent Guarantee; provided,
however, that without the consent of the Holder of each Outstanding Security
affected thereby, a supplemental indenture under this Section may not:

                   (1) change the Stated Maturity of the principal of, or any
         installment of principal of or interest on, any Security, or reduce the
         principal amount thereof or the rate of interest thereon or any premium
         payable upon the redemption thereof, or reduce the amount of the
         principal of an

                                       59
<PAGE>

         Original Issue Discount Security or Indexed Security that would be due
         and payable upon a declaration of acceleration of the Maturity thereof
         pursuant to Section 5.2, or change the coin or currency in which any
         Securities or any premium or the interest thereon is payable, or impair
         the right to institute suit for the enforcement of any such payment on
         or after the Stated Maturity thereof (or, in the case of redemption, on
         or after the Redemption Date);

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

                   (3) change any obligation of the Company to maintain an
         office or agency in the places and for the purposes specified in
         Section 9.2; or

                   (4) make any change in Section 5.7 or this 8.2 except to
         increase any percentage or to provide that certain other provisions of
         this Indenture cannot be modified or waived except with the consent of
         the Holders of each Outstanding Security affected thereby.

                   For the purposes of this Section 8.2, if the Securities of
any series are issuable upon the exercise of warrants, any holder of an
unexercised and unexpired warrant with respect to such series shall not be
deemed to be a Holder of Outstanding Securities of such series in the amount
issuable upon the exercise of such warrants.

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

                   It is not necessary under this Section 8.2 for the Holders to
consent to the particular form of any proposed supplemental indenture or
supplemental agreement, but it is sufficient if they consent to the substance
thereof.

                   Section 8.3. Compliance with Trust Indenture Act. Every
amendment to this Indenture or the Securities of one or more series shall be set
forth in a supplemental indenture that complies with the Trust Indenture Act as
then in effect.

                   Section 8.4. Execution of Supplemental Indentures. In
executing, or accepting the additional trusts created by, any supplemental
indenture permitted by this Article or the modification thereby of the trusts
created by this Indenture, the Trustee shall be entitled to receive, and shall
be fully protected

                                       60
<PAGE>

in relying upon, an Opinion of Counsel stating that the execution of such
supplemental indenture is authorized or permitted by this Indenture. The Trustee
may, but shall not be obligated to, enter into any such supplemental indenture
which adversely affects the Trustee's own rights, duties or immunities under
this Indenture or otherwise. The Trustee shall enter into any such supplemental
indenture if such supplemental indenture does not adversely affect the Trustee's
own rights, duties or immunities under this Indenture or otherwise.

                   Section 8.5. Effect of Supplemental Indentures. Upon the
execution of any supplemental indenture under this Article, this Indenture shall
be modified in accordance therewith, and such supplemental indenture shall form
a part of this Indenture for all purposes; and every Holder of Securities
theretofore or thereafter authenticated and delivered hereunder and of any
coupon appertaining thereto shall be bound thereby; provided that if such
supplemental indenture makes any of the changes described in clauses (1) through
(4) of the first proviso to Section 8.2, such supplemental indenture shall bind
each Holder of a Security who has consented to it and every subsequent Holder of
such Security or any part thereof.

                   Section 8.6. Reference in Securities to Supplemental
Indentures. Securities, including any coupons, of any series authenticated and
delivered after the execution of any supplemental indenture pursuant to this
Article may, and shall if required by the Trustee, bear a notation in form
approved by the Trustee as to any matter provided for in such supplemental
indenture. If the Company shall so determine, new Securities including any
coupons of any series so modified as to conform, in the opinion of the Trustee
and the Company, to any such supplemental indenture may be prepared and executed
by the Company and authenticated and delivered by the Trustee in exchange for
Outstanding Securities including any coupons of such series.

                                   ARTICLE IX

                                    COVENANTS

                   Section 9.1. Payment of Principal, Premium, if any, and
Interest. The Company covenants and agrees for the benefit of the Holders of
each series of Securities that it will duly and punctually pay the principal of,
premium, if any, and interest on the Securities of that series in accordance
with the terms of the Securities of such series, any coupons appertaining
thereto and this Indenture. An installment of principal, premium, if any, or
interest shall be considered paid on the date it is due if the Trustee or Paying
Agent holds on that date money designated for and sufficient to pay the
installment.

                   Section 9.2. Maintenance of Office or Agency. If Securities
of a series are issued as Registered Securities, the Company will maintain in
each Place of Payment for any series of Securities an office or agency where
Securities of that series may be presented or surrendered for payment, where
Securities of that series may be surrendered for registration of transfer or
exchange and where notices and

                                       61
<PAGE>

demands to or upon the Company in respect of the Securities of that series and
this Indenture may be served. If Securities of a series are issuable as Bearer
Securities, the Company will maintain, (i) subject to any laws or regulations
applicable thereto, an office or agency in a Place of Payment for that series,
which is located outside the United States, 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 The International Stock
Exchange of the United Kingdom and the Republic of Ireland Limited, the
Luxembourg Stock Exchange or any other stock exchange located outside the United
States and such stock exchange shall so require, the Company will maintain a
Paying Agent for the Securities of that series in London, Luxembourg or any
other required city located outside the United States, as the case may be, so
long as the Securities of that series are listed on such exchange, and (ii)
subject to any laws or regulations applicable thereto, an office or agency in a
Place of Payment for that series which is located outside the United States
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 any
such office or agency. If at any time the Company shall fail to maintain any
such required office or agency or shall fail to furnish the Trustee with the
address thereof, such presentations, surrenders, notices and demands may be made
or served at the Corporate Trust Office of the Trustee, and the Company hereby
appoints the Trustee as its agent to receive all such presentations, surrenders,
notices and demands.

                   Unless otherwise specified as contemplated by Section 3.1, 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, by check mailed to any
address in the United States, by transfer to an account located in the United
States or upon presentation or surrender in the United States of a Bearer
Security or coupon for payment, even if the payment would be credited to an
account located outside the United States; provided, however, that, if the
Securities of a series are denominated and payable in Dollars, payment of
principal of and any premium or interest on any such Bearer Security shall be
made at an office of a Paying Agent of the Company in the Borough of Manhattan,
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.

                   Subject to the preceding paragraphs, the Company may also
from time to time designate one or more other offices or agencies where the
Securities (including any coupons, if any) of one or more series may be
presented or surrendered for any or all such purposes and may from time to time
rescind such designations; provided, however, that no such designation or
rescission shall in any manner relieve the Company of its obligation to maintain
an office or agency in each Place of Payment for Securities (including any
coupons, if any) 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.

                                       62
<PAGE>

                   Unless otherwise specified as contemplated by Section 3.1,
the Trustee shall initially serve as Paying Agent. The Paying Agent may make
reasonable rules not inconsistent herewith for the performance of its functions.

                   Section 9.3. Money for Securities to Be Held in Trust;
Unclaimed Money. If the Company shall at any time act as its own Paying Agent
with respect to any series of Securities, it will, on or before each due date of
the principal of, premium, if any, 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 sufficient to pay the principal, 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 in writing of its
action or failure so to act.

                   If the Company is not acting as its own Paying Agent, the
Company will cause each Paying Agent for any series of Securities other than the
Trustee to execute and deliver to the Trustee an instrument in which such Paying
Agent shall agree with the Trustee, subject to the provisions of this Section,
that such Paying Agent will:

                   (1) hold all sums held by it for the payment of the principal
         of, premium, if any, or interest on Securities of that 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 that series) in the making of
         any payment of principal, premium, if any, or interest on the
         Securities; and

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

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

                   Any money deposited with the Trustee or any Paying Agent, or
then held by the Company, in trust for the payment of any principal, premium or
interest or other amounts on any Security of any series and remaining unclaimed
for two years after such principal, premium, if any, or interest or other
amounts has become due and payable shall be paid to the Company on Company
Request, or (if then held by the Company) shall be discharged from such trust;
and the Holder of such Security and coupon, if any, shall thereafter, as an
unsecured general creditor, look only to the Company for payment thereof, and
all liability

                                       63
<PAGE>

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 a newspaper published in the English language, customarily published on
each Business Day and of general circulation in The City of New York, or cause
to be mailed to such Holder, 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 9.4. Corporate Existence. Subject to Article VII, the
Company will at all times do or cause to be done all things necessary to
preserve and keep in full force and effect its corporate existence and its
rights and franchises; provided that nothing in this Section 9.4 shall prevent
the abandonment or termination of any right or franchise of the Company if, in
the opinion of the Company, such abandonment or termination is in the best
interests of the Company.

                   Section 9.5. Insurance. The Company covenants and agrees that
it will maintain, and cause each of its Subsidiaries to maintain, insurance with
responsible and reputable insurance companies or associations or through a
program of self-insurance in such amounts and covering such risks as are
consistent with sound business practice for corporations engaged in the same or
a similar business similarly situated.

                   Section 9.6. Reports by the Company. The Company covenants:

                   (a) to file with the Trustee, within 30 days after the
         Company is required to file the same with the Commission, copies of the
         annual reports and of the information, documents and other reports (or
         copies of such portions of any of the foregoing as the Commission may
         from time to time by rules and regulations prescribe) which the Company
         may be required to file with the Commission pursuant to section 13 or
         section 15(d) of the Securities Exchange Act of 1934, as amended; or,
         if the Company is not required to file information, documents or
         reports pursuant to either of such sections, then to file with the
         Trustee and the Commission, in accordance with rules and regulations
         prescribed from time to time by the Commission, such of the
         supplementary and periodic information, documents and reports which may
         be required pursuant to section 13 of the Securities Exchange Act of
         1934, as amended, in respect of a security listed and registered on a
         national securities exchange as may be prescribed from time to time in
         such rules and regulations;

                   (b)  to file with the Trustee and the Commission, in
         accordance with the rules and regulations prescribed from time to time
         by the Commission, such additional information, documents and reports
         with respect to compliance by the Company with the conditions and
         covenants provided for in this Indenture, as may be required from time
         to time by such rules and regulations; and

                                       64
<PAGE>

                  (c) to transmit to all Holders of Securities within 30 days
         after the filing thereof with the Trustee, in the manner and to the
         extent provided in section 313(c) of the Trust Indenture Act, such
         summaries of any information, documents and reports required to be
         filed by the Company pursuant to subsections (a) and (b) of this
         Section 9.6, as may be required by rules and regulations prescribed
         from time to time by the Commission.

                  Subject to the provisions of the Trust Indenture Act and
except as otherwise expressly provided in this Indenture, delivery of such
reports, information and documents to the Trustee is for informational purposes
only, and the Trustee's receipt of such reports, information and documents shall
not constitute constructive notice of any information contained therein or
determinable from information contained therein, including the Company's
compliance with any of its covenants hereunder.

                  Section 9.7. Annual Review Certificate. The Company covenants
and agrees to deliver to the Trustee, within 120 days after the end of each
fiscal year of the Company, 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 9.7, such compliance shall be
determined without regard to any period of grace or requirement of notice
provided under this Indenture.

                  Section 9.8. Calculation of Original Issue Discount. Except as
the Company and the Trustee may otherwise agree, the Company shall file with the
Trustee promptly following the end of each calendar year (a) a written notice
specifying the amount of original issue discount (including daily rates and
accrual periods) accrued on Outstanding Securities as of the end of such year
and (b) such other specific information relating to such original issue discount
as may then be relevant under the Internal Revenue Code of 1986, as amended from
time to time.

                                    ARTICLE X

                                   REDEMPTION

                  Section 10.1. Applicability of Article. Securities (including
coupons, if any) of or within any series which are redeemable in whole or in
part before their Stated Maturity shall be redeemable in accordance with their
terms and (except as otherwise specified as contemplated by Section 3.1 for
Securities of any series) in accordance with this Article.

                  Section 10.2. Election to Redeem; Notice to Trustee. The
election of the Company to redeem any Securities, including coupons, if any,
shall be evidenced by or pursuant to a Board Resolution or a Company Order. In
the case of any redemption at the election of the Company of less than all the
Securities or coupons, if any, of any series having the same terms, the Company
shall, at least 60 days prior to the Redemption Date fixed by the Company
(unless a shorter notice shall be satisfactory to the Trustee),

                                       65
<PAGE>

notify the Trustee of such Redemption Date, of the principal amount of
Securities of such series to be redeemed and, if applicable, of the tenor of the
Securities to be redeemed. In the case of any redemption of Securities (i) prior
to the expiration of any restriction on such redemption provided in the terms of
such Securities or elsewhere in this Indenture or (ii) pursuant to an election
of the Company which is subject to a condition specified in the terms of such
Securities, the Company shall furnish the Trustee with an Officers' Certificate
evidencing compliance with such restriction or condition.

                   Section 10.3. Selection of Securities to Be Redeemed. Unless
otherwise specified as contemplated by Section 3.1, if less than all the
Securities (including coupons, if any) of a series with the same terms are to be
redeemed, the Trustee, not more than 45 days prior to the redemption date, shall
select the Securities of the series to be redeemed in such manner as the Trustee
shall deem fair and appropriate. The Trustee shall make the selection from
Securities of the series that are Outstanding and that have not previously been
called for redemption and may provide for the selection for redemption of
portions (equal to the minimum authorized denomination for Securities, including
coupons, if any, of that series or any integral multiple thereof) of the
principal amount of Securities, including coupons, if any, of such series of a
denomination larger than the minimum authorized denomination for Securities of
that series. The Trustee shall promptly notify the Company in writing of the
Securities selected by the Trustee for redemption and, in the case of any
Securities selected for partial redemption, the principal amount thereof to be
redeemed. If the Securities (including coupons, if any) of a series having
different issue dates, interest rates and maturities (whether or not originally
issued in a Periodic Offering) are to be redeemed, the Company in its discretion
may select the particular Securities or portions thereof to be redeemed and
shall notify the Trustee thereof by such time prior to the relevant redemption
date or dates as the Company and the Trustee may agree.

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

                   Section 10.4. Notice of Redemption. Unless otherwise
specified as contemplated by Section 3.1, notice of redemption shall be given in
the manner provided in Section 1.6 not less than 30 days nor more than 60 days
prior to the Redemption Date to the Holders of the Securities to be redeemed.

                   All notices of redemption shall state:

                   (1)   the Redemption Date;

                   (2)   the Redemption Price;

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

                                       66
<PAGE>

                   (4)   in case any Security is to be redeemed in part only,
         the notice which relates to such Security shall state that on and after
         the Redemption Date, upon surrender of such Security, the holder will
         receive, without a charge, a new Security or Securities of authorized
         denominations for the principal amount thereof remaining unredeemed;

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

                   (6)   that Securities of the series called for redemption and
         all unmatured coupons, if any, appertaining thereto must be surrendered
         to the Paying Agent to collect the Redemption Price;

                   (7)   that, on the Redemption Date, the Redemption Price 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;

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

                   (9)   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

                   (10)  the CUSIP number, if any, of such Securities.

                   Notice of redemption of Securities to be redeemed 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 10.5. Deposit of Redemption Price. On or prior to any
Redemption Date, the Company shall deposit with the Trustee or with a Paying
Agent (or, if the Company is acting as its own Paying Agent, which it may not do
in the case of a sinking fund payment under Article XI, segregate and hold in
trust as provided in Section 9.3) an amount of money in the currency or
currencies (including currency units or composite currencies) in which the
Securities of such series are payable (except as otherwise specified pursuant to
Section 3.1 for the Securities of such series) sufficient to pay on the
Redemption Date the Redemption Price of, and (unless the Redemption Date shall
be an Interest Payment Date) interest accrued to the Redemption Date on, all
Securities or portions thereof which are to be redeemed on that date.

<PAGE>

                   Unless any Security by its terms prohibits any sinking fund
payment obligation from being satisfied by delivering and crediting Securities
(including Securities redeemed otherwise than through a sinking fund), the
Company may deliver such Securities to the Trustee for crediting against such
payment obligation in accordance with the terms of such Securities and this
Indenture.

                   Section 10.6. Securities Payable on Redemption Date. Notice
of redemption having been given as aforesaid, the Securities so to be redeemed
shall, on the Redemption Date, become due and payable at the Redemption Price
therein specified, and from and after such date (unless the Company shall
default in the payment of the Redemption Price and accrued interest) such
Securities shall cease to bear interest and the coupons for any such interest
appertaining to any Bearer Security so to be redeemed, except to the extent
provided below, shall be void. Except as provided in the next succeeding
paragraph, upon surrender of any such Security, including coupons, if any, for
redemption in accordance with said notice, such Security shall be paid by the
Company at the Redemption Price, together with accrued interest to the
Redemption Date; provided, however, that installments of interest on Bearer
Securities whose Stated Maturity is on or prior to the Redemption Date and the
principal of, and premium, if any, on such Bearer Securities shall be payable
only at an office or agency located outside the United States (except as
otherwise provided in Section 9.2) and, unless otherwise specified as
contemplated by Section 3.1, only upon presentation and surrender of coupons for
such interest; and provided, further, that, unless otherwise specified as
contemplated by Section 3.1, installments of interest on Registered Securities
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 3.7.

                   If any Bearer Security surrendered for redemption shall not
be accompanied by all appurtenant coupons maturing after the Redemption Date,
such Bearer Security may be paid after deducting from the Redemption Price an
amount equal to the face amount of all such missing coupons, or the surrender of
such missing coupon or coupons may be waived by the Company and the Trustee if
there be furnished to them such security or indemnity as they may require to
save each of them and any Paying Agent harmless. If thereafter the Holder of
such Bearer Security shall surrender to the Trustee or any Paying Agent any such
missing coupon in respect of which a deduction shall have been made from the
Redemption Price, such Holder shall be entitled to receive the amount so
deducted; provided, however, that interest represented by coupons shall be
payable only at an office or agency located outside of the United States (except
as otherwise provided in Section 9.2) and, unless otherwise specified as
contemplated by Section 3.1, 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 prescribed
therefor in the Security.

                   Section 10.7. Securities Redeemed in Part. Upon surrender of
a Security that is redeemed in part at any Place of Payment therefor (with, if
the Company or the Trustee so require, due

                                       68

endorsement by, or a written instrument of transfer in form satisfactory to the
Company and the Trustee duly executed by, the Holder thereof or his attorney
duly authorized in writing), the Company shall execute and the Trustee shall
authenticate and deliver to the Holder of that Security, without service charge
a new Security or Securities of the same series, having the same form, terms and
Stated Maturity, in any authorized denomination equal in aggregate principal
amount to the unredeemed portion of the principal amount of the Security
surrendered.

                                   ARTICLE XI

                                  SINKING FUNDS

                   Section 11.1. Applicability of Article. The provisions of
this Article shall be applicable to any sinking fund for the retirement of
Securities of a series except as otherwise specified as contemplated by Section
3.1 for Securities of such series.

                   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 sinking fund payment may be subject to
reduction as provided in Section 11.2. Each sinking fund payment shall be
applied to the redemption of Securities of any series as provided for by the
terms of Securities of such series.

                   Section 11.2. Satisfaction of Sinking Fund Payments with
Securities. The Company (i) may deliver Outstanding Securities of a series
(other than any previously called for redemption) together, in the case of
Bearer Securities of such series, with all unmatured coupons appertaining
thereto and (ii) may apply as a credit Securities of a 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 sinking fund payment with respect to the Securities of
such series required to be made pursuant to the terms of such Securities as
provided for by the terms of such series; provided 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
sinking fund payment shall be reduced accordingly.

                   Section 11.3. 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 and the portion thereof, if any, which is to be
satisfied by delivering and crediting Securities of that series pursuant

                                       69
<PAGE>

to Section 11.2 and will also deliver to the Trustee any Securities to be so
delivered. Not less than 30 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 10.3 and cause notice of the
redemption thereof to be given in the name of and at the expense of the Company
in the manner provided in Section 10.4. Such notice having been duly given, the
redemption of such Securities shall be made upon the terms and in the manner
stated in Sections 10.6 and 10.7.

                   This Indenture may be executed in any number of counterparts,
each of which shall be an original, but such counterparts shall together
constitute but one instrument.
