              The Corporation has duly authorized the execution and delivery of
this Indenture to provide for the issuance from time to time of the
Corporation's unsecured debentures, notes or other evidences of indebtedness
(herein collectively called the "Securities," and individually called a
"Security"), which may or may not be convertible into or exchangeable for any
securities of any Person, to be issued in one or more series as provided in this
Indenture.

              All things necessary to make this Indenture a valid agreement of
the Corporation, in accordance with its terms, have been done.

              This Indenture is subject to the provisions of the Trust Indenture
Act of 1939, as amended, and the rules and regulations of the Securities and
Exchange Commission promulgated thereunder that are required to be part of this
Indenture and, to the extent so required, shall be governed by such provisions.

                   Now, Therefore, This Indenture Witnesseth:

              For and in consideration of the premises and the purchase of the
Securities by the Holders thereof, it is mutually covenanted and agreed, for the
equal and proportionate benefit of all Holders of the Securities or of series
thereof, as follows:

             Definitions and Other Provisions of General Application

              Section 1.1 Definitions. For all purposes of this Indenture,
except as otherwise expressly provided or unless the context otherwise requires:

              (a)     the terms defined in this Article have the meanings

Indenture Act, either directly or by reference therein, have the meanings
assigned to them in the Trust Indenture Act;

              (c)     all accounting terms not otherwise defined herein have the
meanings assigned to them in accordance with generally accepted accounting
principles in the United States of America, and, except as otherwise herein
expressly provided, the term "generally accepted accounting principles" with

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

              (e)   the word "or" is always used inclusively (for example, the
phrase "A or B" means "A or B or both," not "either A or B but not both").

on each Business Day, whether or not published on Saturdays, Sundays or
holidays, and of general circulation in the place in connection with which the
term is used or in the financial community of such place. Where successive
publications are required to be made in Authorized Newspapers, the successive
publications may be made in the same or in different newspapers in the same city
meeting the foregoing requirements and in each case on any Business Day.

              "Bank" means The Northern Trust Company, an Illinois banking
corporation, and its successors (whether by consolidation, merger, conversion or
transfer of substantially all their assets and business or otherwise) so long as
The Northern Trust Company or any successor is a Subsidiary.

              "Bankruptcy Law" means Title 11 of the United States Code or any
similar United States federal or state law for the relief of debtors.

              "Bearer Security" means any Security established pursuant to
Section 2.1 which is payable to bearer and shall bear the legend specified in
Section 2.5.

              "Board of Directors" means the board of directors of the

          (a) Any request, demand, authorization, direction, notice, consent,
waiver or other action provided in or pursuant to this Indenture to be made,
given or taken by Holders may be embodied in and evidenced by one or more
instruments of substantially similar tenor signed by such Holders in person or
by an agent duly appointed in writing. If Securities of a series are issuable as
Bearer Securities, any request, demand, authorization, direction, notice,
consent, waiver or other action provided in or pursuant to this Indenture to be
made, given or taken by Holders may, alternatively, be embodied in and evidenced
by the record of Holders of Securities voting in favor thereof, either in person
or by proxies duly appointed in writing, at any meeting of Holders of Securities
duly called and held in accordance with the provisions of Article Thirteen, or a
combination of such instrument or instruments and any such record. Except as
herein otherwise expressly provided, such action shall become effective when
such instrument or

                                        8

<PAGE>

instruments or record or both are delivered to the Trustee and, where it is
hereby expressly required, to the Corporation or both. Such instrument or
instruments and any such record (and the action embodied therein and evidenced
thereby) are herein sometimes referred to as the "Act" of the Holders signing
such instrument or instruments and so voting at any such meeting. Proof of
execution of any such instrument or of a writing appointing any such agent, or
of the holding by any Person of a Security, shall be sufficient for any purpose
of this Indenture and (subject to Section 6.1) conclusive in favor of the
Trustee and the Corporation if made in the manner provided in this Section. The
record of any meeting of Holders of Securities shall be proved in the manner
provided in Section 13.6.

          Notwithstanding the foregoing, with respect to any Global Security,
nothing herein shall prevent the Corporation, the Trustee, or any agent of the
Corporation or the Trustee, from giving effect to any request, demand,
authorization, direction, notice, consent, waiver or other action provided in
this Indenture to be given or taken by a Depositary or impair, as between a
Depositary and such holders of beneficial interests, the operation of customary
practices governing the exercise of the rights of the Depositary (or its
nominee) as Holder of any Security.

          Without limiting the generality of this Section 1.4, unless otherwise
provided in or pursuant to this Indenture, a Holder, including a Depositary that
is a Holder of a Global Security, may make, give or take, by a proxy or proxies
duly appointed in writing, any request, demand, authorization, direction,
notice, consent, waiver or other action provided in or pursuant to this
Indenture to be made, given or taken by Holders, and a Depositary that is a
Holder of a Global Security may give its proxy or proxies to the Depositary's
participants or the beneficial owners of interests in any such Global Security,
as the case may be, through such Depositary's standing instructions and
customary practices.

          Subject to the next succeeding paragraph, the Corporation may, in the
circumstances permitted by the Trust Indenture Act, fix any day as the record
date for the purpose of determining the Holders of Securities of any series
entitled to give or take any request, demand, authorization, direction, notice,
consent, waiver or other action, or to vote on any action, authorized or
permitted to be given or taken by Holders of Securities of such series. If not
set by the Corporation prior to the first solicitation of a Holder of Securities
of such series made by any Person in respect of any such action, or in the case
of any such vote, prior to such vote, the record date for any such action or
vote shall be the 30th day prior to such first solicitation or vote, or, if
later, the date of the most recent list of Holders required to be provided
pursuant to Section 7.1, as the case may be. With regard to any record date for
action to be taken by the Holders of one or more series of Securities, only the
Holders of Securities of such series on such date (or their duly designated
proxies) shall be entitled to give or take, or vote on, the relevant action.

          The Trustee shall fix a record date for the purpose of determining the
Persons who are beneficial owners of interests in any permanent Global Security
held by a Depositary and who are entitled under the procedures of such
Depositary to make, give or take, by a proxy or proxies duly appointed in
writing, any request, demand, authorization, direction, notice, consent, waiver
or other action provided in or pursuant to this Indenture to be made, given or
taken by Holders. If such a record date is fixed, the Holders on such record
date or their duly appointed proxy or proxies, and only such Persons, shall be
entitled to make, give or take such request,

                                        9

<PAGE>

demand, authorization, direction, notice, consent, waiver or other action,
whether or not such Holders remain Holders after such record date. No such
request, demand, authorization, direction, notice, consent, waiver or other
action shall be valid or effective if made, given or taken more than 90 days
after such record date.

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

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

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

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

          (f) Any request, demand, authorization, direction, notice, consent,
election, 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 Corporation in reliance thereon, whether or not notation of such action is
made upon such Security.

demand, authorization, direction, notice, consent, election, waiver or other Act
of Holders of a series of Securities or other document provided or permitted by

<PAGE>

          Section 1.6 Notice to Holders of Securities; Waiver. Except as
otherwise expressly provided herein, where this Indenture provides for notice to
Holders of Securities (of any series) of any event,

          (a) such notice shall be sufficiently given to Holders of Registered
Securities of such series if in writing and mailed, first-class postage prepaid,
to each Holder of a Registered Security of such series affected by such event,
at his address as it appears in the Security Register, not later than the latest
date, and not earlier than the earliest date, prescribed for the giving of such
Notice; and

Securities of such series if published in an Authorized Newspaper in the Borough
of Manhattan, The City of New York and, if the Securities of such series are
then listed on The London Stock Exchange and the Republic of Ireland and such
stock exchange shall so require, in London and, if the Securities of such series
are then listed on the Luxembourg Stock Exchange and such stock exchange shall
so require, in Luxembourg and, if the Securities of such series are then listed
on any other stock exchange outside the United States and such stock exchange
shall so require, in any other required city outside the United States or, if
not practicable, in Europe, on a Business Day at least twice, the first such
publication to be not earlier than the earliest date and not later than the
latest date prescribed for the giving of such notice.

          In case by reason of the suspension of regular mail service or by
reason of any other cause it shall be impracticable to give such notice by mail,
then such notification as shall be made with the approval of the Trustee shall
constitute a sufficient notification for every purpose hereunder. In any case
where notice to Holders of Registered Securities is given by mail, neither the
failure to mail such notice, nor any defect in any notice so mailed, to any
particular Holder of a Registered Security shall affect the sufficiency of such
notice with respect to other Holders of Registered Securities or the sufficiency
of any notice by publication to Holders of Bearer Securities given as provided
above.

          In case by reason of the suspension of publication of any Authorized
Newspaper or Authorized Newspapers or by reason of any other cause it shall be
impracticable to publish any notice to Holders of Bearer Securities of any
series as provided above, then such notification to Holders of such Bearer
Securities as shall be given with the approval of the Trustee for such series
shall constitute sufficient notice to such Holders for every purpose hereunder.
Neither failure to give notice by publication to Holders of Bearer Securities as
provided above, nor any

                                       11

<PAGE>

defect in any notice so published, shall affect the sufficiency of any notice
mailed to Holders of Registered Securities as provided above.

              Where this Indenture provides for notice in any manner, such
notice may be waived in writing by the Person entitled to receive such notice,
either before or after the event, and such waiver shall be the equivalent of
such notice. Waivers of notice by Holders of Securities 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 Language of Notices, Etc.  Any request, demand,
authorization, direction, notice, consent, election 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.

hereof limits, qualifies or conflicts with any duties under any required
provision of the Trust Indenture Act deemed included herein by Section 318(c)

are issuable in global form, any such Security may provide that it or any number
of such Securities shall represent the aggregate amount of all Outstanding
Securities of such series (or such lesser amount as is permitted by the terms
thereof) 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 increased or reduced to reflect exchanges. Any endorsement of any

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 Order of the Corporation to be delivered
pursuant to Sections 3.3 or 3.4 with respect thereto. 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

nominee of the Depositary to the Depositary or another nominee of the Depositary

Bearer Securities of such series, if any, shall be substantially identical
except, in the case of Registered Securities, as to denomination and except as
may otherwise be provided in or pursuant to the Board Resolution and set forth
in the Officers' Certificate, or provided in the indenture supplemental hereto,
establishing the series.

              If any of the terms of the series are established by action taken
pursuant to a Board Resolution, a copy of an appropriate record of such action
shall be certified by the Corporate Secretary or an Assistant Corporate
Secretary of the Corporation and delivered to the Trustee at or prior to the
delivery of the Officers' Certificate setting forth the terms of the series.
Such Board Resolution may provide general terms or parameters for Securities of
such series and may provide that the specific terms of particular Securities of
such series, and the Persons

                                       17

<PAGE>

authorized to determine such terms or parameters may be determined in accordance
with or pursuant to the Order of the Corporation referred to in the third
paragraph of Section 3.3.

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

              Section 3.3 Execution, Authentication, Delivery and Dating.  The

Board, a Vice Chairman, its President or one of its Vice Presidents, under its
corporate seal reproduced thereon attested by its Corporate Secretary or one of
its Assistant Corporate Secretaries. The signature of any of these officers on
the Securities may be manual or facsimile. Coupons shall bear the facsimile
signature of the Treasurer or any Assistant Treasurer of the Corporation.

              Securities and coupons bearing the manual or facsimile signatures
of individuals who were at any time relevant to the authorization thereof the
proper officers of the Corporation shall bind the Corporation, 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 after the execution and delivery
of this Indenture, the Corporation may deliver Securities of any series executed
on behalf of the Corporation to the Trustee for authentication by the Trustee
together with an Order of the Corporation for the authentication and delivery of
such Securities, and the Trustee in accordance with such Order shall
authenticate and deliver such Securities; provided, that in connection with its
original issuance, a Bearer Security may be delivered only outside the United
States and only if the Trustee shall have received from the Person entitled to
receive such Bearer Security a certificate in the form required by Section 3.11;
and provided further, that, with respect to Securities of a series constituting
a medium-term note program, the Trustee shall authenticate and deliver
Securities of such series for original issue from time to time in the aggregate
principal amount established for such series pursuant to such procedures
acceptable to the Trustee and to such recipients as may be specified from time
to time by an Order of the Corporation. The maturity dates, original issue
dates, interest rates and any other terms of the Securities of a subseries of
any medium-term note program shall be determined by or pursuant to such Order of
the Corporation and such procedures.

              In authenticating Securities in accordance with an Order of the
Corporation, and accepting the additional responsibilities under this Indenture
in relation to such Securities, the Trustee shall be entitled to receive, and
(subject to Sections 315(a) through 315(d) of the Trust Indenture Act) shall be
fully protected in relying upon:

              (a)   the Board Resolution or indenture supplemental hereto
establishing the form of the Securities of the series pursuant to Section 2.1
and the terms of the Securities of the series pursuant to Section 3.1 (or, in
the case of a Board Resolution, pursuant to which such form and terms are
established);

                                       18

<PAGE>

              (b)   an Officer's Certificate pursuant to Sections 2.1 and 3.1
and complying with Section 1.2; and

              (c)   an Opinion of Counsel complying with Section 1.2 stating,

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

                    (ii)   that the terms of such Securities have been
              established by or pursuant to a Board Resolution or by an
              indenture supplemental hereto, as permitted by Sections 2.1 and
              3.1 and in conformity with the provisions of this Indenture;

                    (iii)  that such Securities, together with the coupons, if
              any, appertaining thereto, when authenticated and delivered by the
              Trustee and issued by the Corporation in the manner and subject to
              any customary conditions specified in such Opinion of Counsel,
              shall constitute valid and legally binding obligations of the
              Corporation entitled to the benefits provided by the Indenture,
              enforceable in accordance with their respective terms, except to
              the extent that the enforcement of such obligations may be subject
              to bankruptcy laws or insolvency laws or other similar laws,
              general principles of equity and such other qualifications as such
              counsel shall conclude are customary or do not materially affect
              the rights of the Holders of such Securities;

                    (iv)   that all laws and requirements in respect of the
              execution and delivery of the Securities have been complied with;
              and

                    (v)    such other matters as the Trustee may reasonably
              request.

              With respect to Securities of a subseries of a medium-term note
program, the Trustee may conclusively rely on the documents and opinion
delivered pursuant to Sections 2.1 and 3.1 and this Section 3.3, as applicable
(unless revoked by superseding comparable documents or opinions), with respect
to the establishment of the medium-term note program as to the authorization of
the Board of Directors of the Corporation of any Securities delivered hereunder,
the form thereof and the legality, validity, binding effect and enforceability
thereof.

              Notwithstanding the provisions of Section 3.1 and of the preceding
two paragraphs, if not all the Securities of any series are to be issued at one
time, it shall not be necessary to deliver the Officers' Certificate otherwise
required pursuant to Section 3.1 or the documents otherwise required pursuant to
the preceding clauses (a), (b) or (c) prior to or at the time of issuance of
each Security, but such documents shall be delivered prior to or at the time of
issuance of the first Security of such series and shall pertain to all of the
Securities of such series. After any such first delivery, any separate Request
by the Corporation that the Trustee authenticate Securities of such series for
original issue shall be deemed to be a certification by the Corporation that all
conditions precedent provided for in this Indenture relating to authentication
and delivery of such Securities continue to have been complied with.

                                       19

<PAGE>

              If such forms or terms have been so established by or pursuant to
a Board Resolution or by an indenture supplemental hereto as permitted by
Sections 2.1 and 3.1, the Trustee shall have the right to decline to
authenticate and deliver any Securities of such series:

                  (x)   if the Trustee, being advised by counsel, determines
that such action may not lawfully be taken;

                  (y)   if the Trustee in good faith by its board of directors,
executive committee or a committee of directors or Responsible Officers of the
Trustee in good faith determines that such action would expose the Trustee to
personal liability to Holders of any Outstanding series of Securities; or

                  (z) if the issue of such Securities pursuant to this Indenture
shall affect the Trustee's own rights, duties and immunities under the
Securities and this Indenture or otherwise in a manner which is not acceptable
to the Trustee.

              If the Corporation shall establish pursuant to Section 3.1 that
the Securities of a series are to be issued in whole or in part in the form of
one or more Global Securities, then the Corporation shall execute and the
Trustee shall, in accordance with this Section and the Order of the Corporation
with respect to such series, authenticate and deliver one or more Global
Securities in permanent form that (A) 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 Global Security or
Securities, (B) shall be registered, if in registered form, in the name of the
Depositary for such Global Security or Securities or the nominee of such
Depositary, (C) shall be delivered by the Trustee to such Depositary or pursuant
to such Depositary's instruction and (D) shall bear a legend as required by
Section 2.4.

              Each Registered Security shall be dated the date of its
authentication. Each Global Security, each Bearer Security and any temporary
Bearer Security in global form shall be dated as of the date specified as
contemplated by Section 3.1.

              No Security or related coupon shall be entitled to any benefit
under this Indenture or be valid or obligatory for any purpose unless there
appears on such Security a certificate of authentication substantially in the
form provided for herein executed by the Trustee by manual signature, and such
certificate upon any Security shall be conclusive evidence, and the only
evidence, that such Security has been duly authenticated and delivered hereunder
and is entitled to the benefits of this Indenture. 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 and paid or
payment duly provided for have been detached and canceled.

              Section 3.4 Temporary Securities.  Pending the preparation of
definitive Securities of any series, the Corporation may execute, and upon an
Order of the Corporation the Trustee shall authenticate and deliver, temporary
Securities which are printed, lithographed, typewritten, mimeographed or
otherwise produced, in any authorized denomination, substantially of the tenor
of the definitive Securities in lieu of which they are issued, in registered
form or, if authorized, in bearer form with one or more coupons or without
coupons, and with such appropriate insertions, omissions, substitutions and
other variations as the officers executing

                                       20

<PAGE>

such Securities may determine, as evidenced by their execution of such
Securities (but which do not affect the rights or duties of the Trustee). In the
case of Bearer Securities of any series, such temporary Securities may be in
global form, representing all of the outstanding Bearer Securities of such
series.

          Except in the case of temporary Securities in global form, which shall
be exchanged in accordance with the provisions thereof, if temporary Securities
of any series are issued, the Corporation shall cause definitive Securities of
that series to be prepared without unreasonable delay. After the preparation of
definitive Securities of such series, the temporary Securities of such series
shall be exchangeable for definitive Securities of such series upon surrender of
the temporary Securities of such series at the office or agency of the
Corporation in a Place of Payment for that series, without charge to the Holder.
Upon surrender for cancellation of any one or more temporary Securities of any
series (accompanied by any unmatured coupons appertaining thereto), the
Corporation shall execute and the Trustee shall authenticate and deliver in
exchange therefor (at an office or agency of the Corporation in the case of
Bearer Securities) a like principal amount of definitive Securities of the same
series of authorized denominations and of like tenor; provided, 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 in the form required by Section 3.11. Until so
exchanged, the temporary Securities of any series, including temporary
Securities in global form, shall in all respects be entitled to the same
benefits under this Indenture as definitive Securities of such series.

          Section 3.5 Registration, Registration of Transfer and Exchange. The
Corporation shall cause to be kept at one of its offices or agencies designated
pursuant to Section 10.2 a register (referred to as the "Security Register") in
which, subject to such regulations as it may prescribe, theCorporation shall
provide for the registration of Registered Securities of each series and of
transfers and exchanges of Registered Securities of such series. Said office or
agency is hereby appointed the security registrar (referred to as the "Security
Registrar") for the purpose of registering Registered Securities of each series
and transfers and exchanges of Registered Securities of such series as herein
provided.

          Upon surrender for registration of transfer of any Registered Security
of any series at the office or agency in a Place of Payment maintained for such
purpose for such series, the Corporation 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, Stated
Maturity and original issue date, of any authorized denominations and of like
tenor and aggregate principal amount.

          At the option of the Holder, Registered Securities of any series
(except a Global Security representing all or a portion of such series) may be
exchanged for Registered Securities of the same series, Stated Maturity and
original issue date, of any authorized denominations and of like tenor and
aggregate principal amount, upon surrender of the Securities to be exchanged at
any such office or agency.

                                       21

          At the option of the Holder, Bearer Securities of any series may be
exchanged for Registered Securities of the same series, Stated Maturity and
original issue date, 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 Corporation and
the Trustee in an amount equal to the face amount of such missing coupon or
coupons, or the surrender of such missing coupon or coupons may be waived by the
Corporation and the Trustee if there is furnished to them such security or
indemnity as they may require to save each of them and any Paying Agent
harmless. If thereafter the Holder of such Security surrenders 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, that except as otherwise provided in Section 10.2, 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 a 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 (1)
any Regular Record Date and before the opening of business at such office or
agency on the relevant Interest Payment Date, or (2) any Special Record Date and
before the opening of business at such office or agency on the related date for
payment of Defaulted Interest, such Bearer Security shall be surrendered without
the coupon relating to such Interest Payment Date or proposed date of payment,
as the case may be.

          Whenever any Securities are so surrendered for exchange, the
Corporation 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 exchange of
Securities shall be the valid obligations of the Corporation, evidencing the
same debt, and entitled to the same benefits under this Indenture, as the
Securities surrendered upon such registration of transfer or exchange.

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

          No service charge shall be made for any registration of transfer or
exchange of Securities, but the Corporation 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, 9.6 or 11.7 not involving any transfer.

          The Corporation shall not be required (a) to issue, to register the
transfer of or to exchange Securities of any series during a period of 15
Business Days immediately preceding the

                                       22

<PAGE>

date notice is given identifying the serial numbers of the Securities of that
series called for redemption, or (b) to issue, to register the transfer of or to
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 (c) 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,
provided, that such Registered Security shall be immediately surrendered for
redemption with written instruction for payment consistent with the provisions
of this Indenture.

          Notwithstanding the foregoing, except as otherwise specified as
contemplated by Section 3.1, any Global Security shall be exchangeable pursuant
to this Section 3.5 or Sections 3.4, 3.6, 9.6 or 11.7 for Securities registered
in the name of, and a transfer of a Global Security of any series may be
registered to, any Person other than the Depositary for such Global Security or
its nominee only if:

          (i)    such Depositary notifies the Corporation that it is unwilling
     or unable to continue as Depositary for such Global Security, or such
     Depositary ceases to be a clearing agency registered under the Securities
     Exchange Act of 1934, as amended, and a successor Depositary is not
     appointed by the Corporation within 90 days;

          (ii)   the Corporation executes and delivers to the Trustee an Order
     of the Corporation that such Global Security shall be so exchangeable and
     the transfer thereof so registrable; or

          (iii)  there shall have occurred and be continuing an Event of Default
     or an event which, with the giving of notice or lapse of time, would
     constitute an Event of Default with respect to the Securities of such
     series.

Upon the occurrence in respect of any Global Security of any series of any one
or more of the conditions specified in clauses (i), (ii) or (iii) of the
preceding sentence or such other conditions as may be specified as contemplated
by Section 3.1 for such series, then without unnecessary delay, but in any event
not later than the earliest date on which such interests may be so exchanged,
the Corporation shall deliver to the Trustee definitive Securities of that
series in aggregate principal amount equal to the principal amount of such
Global Security, executed by the Corporation.

          On or after the earliest date on which such interests may be so
exchanged, such Global Securities shall be surrendered from time to time by the
Depositary and in accordance with instructions given to the Trustee and the
Depositary (which instructions shall be in writing but need not be contained in
or accompanied by an Officers' Certificate or be accompanied by an Opinion of
Counsel), as shall be specified in the Order of the Corporation with respect
thereto to the Trustee, as the Corporation's agent for such purpose, to be
exchanged, in whole or in part, for definitive Securities of the same series
without service charge. The Trustee shall authenticate and make available for
delivery, in exchange for each portion of such surrendered Global Security, a
like aggregate principal amount of definitive Securities of the same series of
authorized denominations and of like tenor as the portion of such Global
Security to be exchanged which (unless the Securities of the series are not
issuable both as Bearer Securities and as Registered Securities, in which case
the definitive Securities exchanged for the Global

                                       23

<PAGE>

Security shall be issuable only in the form in which the Securities of the
series are issuable, as specified as contemplated by Section 3.1) shall be in
the form of Bearer Securities or Registered Securities, or any combination
thereof, as shall be specified by the beneficial owner thereof; provided, that
no such exchanges may occur during a period beginning at the opening of business
15 Business Days before any selection of Securities of the series to be redeemed
and ending on the relevant Redemption Date; and provided further, that (unless
otherwise specified as contemplated by Section 3.1) no Bearer Security delivered
in exchange for a portion of a Global Security shall be mailed or otherwise
delivered to any location in the United States.

          Promptly following any such exchange in part, such Global Security
shall be returned by the Trustee to the Depositary in accordance with the
instructions of the Corporation referred to above. If a Registered Security is
issued in exchange for any portion of a Global Security after the close of
business at the office or agency where such exchange occurs on any Regular
Record Date for such Security and before the opening of business at such office
or agency on the next Interest Payment Date, or any Special Record Date for such
Security and before the opening of business at such office or agency on the
related proposed date for payment of interest or Defaulted Interest, as the case
may be, interest shall not be payable on such Interest Payment Date or proposed
date for payment, as the case may be, in respect of such Registered Security,
but shall be payable on such Interest Payment Date or proposed date for payment,
as the case may be, only to the Person to whom interest in respect of such
portion of such Global Security is payable in accordance with the provisions of
this Indenture.

          Section 3.6 Mutilated, Destroyed, Lost and Stolen Securities. If any
mutilated Security or a Security with a mutilated coupon appertaining to it is
surrendered to the Trustee, the Corporation shall execute and the Trustee shall
authenticate and deliver in exchange therefor a new Security of the same series,
Stated Maturity and original issue date, and of like tenor and principal amount
and bearing a number not contemporaneously outstanding, with coupons
corresponding to the coupons, if any, appertaining to the surrendered Security.

          If there shall be delivered to the Corporation and the Trustee (1)
evidence to their satisfaction of the destruction, loss or theft of any Security
or coupon and (2) such security or indemnity as may be required by them to save
each of them and any agent of either of them harmless, then, in the absence of
notice to the Corporation or the Trustee that such Security or coupon has been
acquired by a bona fide purchaser, the Corporation shall execute and upon its
Request 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 new Security of the same series, Stated Maturity
and original issue date, and of like tenor and principal amount and bearing a
number not contemporaneously outstanding, with coupons corresponding to the
coupons, if any, appertaining to such destroyed, lost or stolen Security or to
the Security to which such destroyed, lost or stolen coupon appertains.

          In case any such mutilated, destroyed, lost or stolen Security or
coupon has become or is about to become due and payable, the Corporation in its
discretion may, instead of issuing a new Security, pay such Security or coupon;
provided, that payment of principal of (and premium, if any) and any interest on
Bearer Securities shall, except as otherwise provided in Section 10.2, be
payable only at an office or agency located outside the United States; and

                                       24

<PAGE>

provided further, that with respect to any such coupons, interest represented
thereby (but not any additional amounts payable as provided in Section 10.6),
shall be payable only upon presentation and surrender of the coupons
appertaining thereto.

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

          Every new Security of any series, with its coupons, if any, issued
pursuant to this Section in lieu of any mutilated, 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 Corporation, whether or not the mutilated, destroyed, lost or
stolen Security and its coupons, if any, or the mutilated, destroyed, lost or
stolen coupon shall be at any time enforceable by anyone, and any such new
Security and coupons, if any, shall be entitled to all the benefits of this
Indenture equally and proportionately with any and all other Securities of that
series and their coupons, if any, duly issued hereunder.

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

          Section 3.7 Payment of Interest; Interest Rights Preserved. Unless
otherwise provided as contemplated by Section 3.1 with respect to any series of
Securities, interest on any Registered Security which is payable, and is
punctually paid or duly provided for, on any Interest Payment Date shall be paid
to the Person in whose name that Security (or one or more Predecessor
Securities) is registered at the close of business on the Regular Record Date
for such interest. Interest, if any, on any Bearer Securities shall be paid to
Holders of coupons. In case a Bearer Security of any series is surrendered in
exchange for a Registered Security of such series after the close of business
(at an office or agency in a Place of Payment for such series) on any Regular
Record Date and before the opening of business (at such office or agency) on the
next succeeding Interest Payment Date, such Bearer Security shall be surrendered
without the coupon relating to such Interest Payment Date and interest shall not
be payable on such Interest Payment Date in respect of the Registered Security
issued in exchange for such Bearer Security, but shall be payable only to the
Holder of such coupon when due in accordance with the provisions of this
Indenture.

          Any interest on a 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 Corporation, at its election in
each case, as provided in clause (a) or (b) below:

          (a)  The Corporation may elect to make payment of any Defaulted
Interest to the Persons in whose names the Registered Securities of such series
(or their respective Predecessor Securities) are registered at the close of
business on a Special Record Date for the payment of such Defaulted Interest,
which shall be fixed in the following manner. The

                                       25

<PAGE>

Corporation shall notify the Trustee in writing of the amount of Defaulted
Interest proposed to be paid on each Registered Security of such series and the
date of the proposed payment, and at the same time the Corporation 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 provided in this clause.
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 Corporation of such Special Record Date and, in the
name and at the expense of the Corporation, shall cause notice of the proposed
payment of such Defaulted Interest and the Special Record Date therefor to be
mailed, first-class postage prepaid, to each Holder of Registered Securities of
such series at the address of such Holder as it appears in the Security
Register, not less than 10 days prior to such Special Record Date. The Trustee
may, in its discretion, in the name and at the expense of the Corporation, cause
a similar notice to be published at least once in an Authorized Newspaper in
each Place of Payment, but such publication shall not be a condition precedent
to the establishment of such Special Record Date. Notice of the proposed payment
of such Defaulted Interest and the Special Record Date therefor having been so
mailed, such Defaulted Interest shall be paid to the Persons in whose names the
Registered Securities of such series (or their respective Predecessor
Securities) are registered at the close of business on such Special Record Date
and shall no longer be payable pursuant to the following clause (b). In case a
Bearer Security of any series is surrendered at the office or agency in a Place
of Payment for such series in exchange for a Registered Security of such series
after the close of business at such office or agency on any Special Record Date
and before the opening of business at such office or agency on the related
proposed date for payment of Defaulted Interest, such Bearer Security shall be
surrendered without the coupon relating to such proposed date of payment and
Defaulted Interest shall not be payable on such proposed date of payment in
respect of the Registered Security issued in exchange for such Bearer Security,
but shall be payable only to the Holder of such coupon when due in accordance
with the provisions of this Indenture.

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

          Subject to the foregoing provisions of this Section, each 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 a
Registered Security for registration of transfer, the Corporation, the Trustee
and any agent of the Corporation or the Trustee may deem and treat the Person in
whose name such Registered

                                       26

<PAGE>

Security is registered as the absolute owner of such Registered Security for the
purpose of receiving payment of principal of (and premium, if any) and (subject
to Section 3.7) interest, if any, on such Security and for all other purposes
whatsoever, whether or not such Security is overdue, and neither the
Corporation, the Trustee nor any agent of the Corporation or the Trustee shall
be affected by any notice to the contrary.

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

          No holder of any beneficial interest in any Global Security held on
its behalf by a Depositary (or its nominee) shall have any rights under this
Indenture with respect to such Global Security or any Security represented
thereby, and such Depositary may be treated by the Corporation, the Trustee, and
any agent of the Corporation or the Trustee as the owner of such Global Security
or any Security represented thereby for all purposes whatsoever. None of the
Corporation, the Trustee, any Paying Agent or the Security Registrar 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 Global Security
or for maintaining, supervising or reviewing any records relating to such
beneficial ownership interests.

          Section 3.9 Cancellation. All Securities and coupons surrendered for
payment, redemption, registration of transfer or exchange or for credit against
any sinking fund payment shall, if surrendered to any Person other than the
Trustee, be delivered to the Trustee and shall be promptly canceled by the
Trustee. The Corporation may at any time deliver to the Trustee for cancellation
any Securities previously authenticated and delivered hereunder which the
Corporation may have acquired in any manner whatsoever, and all Securities so
delivered shall be promptly canceled by the Trustee. No Securities shall be
authenticated in lieu of or in exchange for any Securities canceled as provided
in this Section, except as expressly permitted by this Indenture. All canceled
Securities and coupons held by the Trustee shall be destroyed and certification
of their destruction delivered to the Corporation, unless an Order of the
Corporation shall direct that canceled Securities be returned to the
Corporation.

          The repayment of any principal amount of Securities pursuant to any
option of the Holder to require repayment of Securities before their Stated
Maturity, for purposes of this Section 3.9, shall not operate as a payment,
redemption or satisfaction of the indebtedness represented by such Securities
unless and until the Corporation, at its option, shall deliver or surrender the
same to the Trustee with an Order of the Corporation directing that such
Securities be canceled.

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

          Section 3.11 Form of Certification by a Person Entitled to Receive a
Bearer Security. Whenever any provision of this Indenture or the form of
Security contemplates that certification be given by a Person entitled to
receive a Bearer Security, such certification shall be provided substantially in
the form of the following certificate, with only such changes as shall be
approved by the Corporation and of which the Corporation shall have given
written notice to the Trustee:

                       [Form of Certificate to Be Given By
                   Person Entitled to Receive Bearer Security]

                                   Certificate

                               [Name of Security]

          This is to certify that the above-captioned Security is not being
acquired by or on behalf of a United States person, or for offer to resell or
for resale to a United States person, or, if a beneficial interest in the
Security is being acquired by a United States person, that such person is a
financial institution or is acquiring through a financial institution and that
the Security is held by a financial institution that has agreed in writing to
comply with the requirements of Section 165(j)(3)(A), (B) or (C) of the Internal
Revenue Code of 1986, as amended, and the regulations thereunder and that such
person or financial institution is not purchasing for offer to resell or for
resale within the United States. If this certificate is being provided by a
clearing organization, it is based on statements provided to it by its member
organizations. As used herein, "United States" means the United States of
America (including the States and the District of Columbia), its territories and
possessions and other areas subject to its jurisdiction, and "United States
person" means any citizen or resident of the United States, any corporation,
partnership or other entity created or organized in or under the laws of the
United States or any political subdivision thereof and any estate or trust the
income of which is subject to United States federal income taxation regardless
of its source. If the undersigned is a dealer, the undersigned agrees to obtain
a similar certificate from each person entitled to delivery of any of the
above-captioned Securities in bearer form purchased from it; provided, that if
the undersigned has actual knowledge that the information contained in such a
certificate is false, the undersigned shall not deliver a Security in temporary
or definitive bearer form to the person who signed such certificate
notwithstanding the delivery of such certificate to the undersigned.

          We undertake to advise you by telecopy if the above statement as to
beneficial ownership is not correct on the date of delivery of the
above-captioned Securities in bearer form as to all of such Securities.

          We understand that this certificate is required in connection with
certain tax legislation in the United States. If administrative or legal
proceedings are commenced or threatened in connection with which this
certificate is or would be relevant, we irrevocably authorize you to produce
this certificate or a copy thereof to any interested party in such proceedings.

          Section 3.12 CUSIP, ISIN and Common Code Numbers. The Corporation in
issuing the Securities may use "CUSIP," "ISIN" or "Common Code" numbers (if then
generally in use) and, if so, the Trustee shall use "CUSIP" numbers, "ISIN" or
"Common Code" in notices of redemption as a convenience to Holders; provided,
however, that any such notice may state that no representation is made as to the
correctness of such numbers either as printed on the Securities or as contained
in any notice of a redemption and that reliance may be placed only on the other
identification numbers printed on the Securities, and any such redemption shall
not be affected by any defect in or omission of such numbers.

                           Satisfaction and Discharge

          Section 4.1 Satisfaction and Discharge of Indenture. This Indenture
shall upon a Request of the Corporation cease to be of further effect (except as
to any surviving rights of registration of transfer or exchange or conversion of
Securities herein expressly provided for, and any right to receive additional
amounts, as provided in Section 10.6), and the Trustee, at the expense of the
Corporation, shall execute proper instruments acknowledging satisfaction and
discharge of this Indenture, when:

          (a)  either

               (i)  all Securities theretofore authenticated and delivered and
     all coupons appertaining thereto (other than (w) coupons appertaining to
     Bearer Securities surrendered for exchange for Registered Securities and
     maturing after such exchange, whose surrender is not required or has been
     waived as provided in Section 3.5, (x) Securities and coupons which have
     been destroyed, lost or stolen and which have been replaced or paid as
     provided in Section 3.6, (y) coupons appertaining to Securities called for
     redemption and maturing after the relevant Redemption Date, whose surrender
     has been waived as provided in Section 11.6, and (z) Securities and coupons
     for whose payment money has theretofore been deposited in trust or
     segregated and held in trust by the Corporation and thereafter repaid to
     the Corporation or discharged from such trust, as provided in Section 10.3)
     have been delivered to the Trustee for cancellation; or

               (ii) all such Securities not theretofore delivered to the Trustee
     for cancellation

                    (1)  have become due and payable, or

                    (2)  shall become due and payable at their Stated Maturity

          arrangements satisfactory to the Trustee for the giving of notice of
          redemption by the Trustee in the name, and at the expense, of the
          Corporation,

     and the Corporation, in the case of (ii)(1), (2) or (3) above, has
     deposited or caused to be deposited with the Trustee as trust funds in
     trust dedicated solely for such purpose an

                                       29

<PAGE>

       amount sufficient, without reinvestment, to pay and discharge the entire
       indebtedness on such Securities and coupons not theretofore delivered to
       the Trustee for cancellation, for principal (and premium, if any) and
       interest, if any, to the date of such deposit (in the case of Securities
       which have become due and payable) or to the Stated Maturity or
       Redemption Date, as the case may be;

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

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

          In the event there are Securities of two or more series hereunder, the
Trustee shall be required to execute an instrument acknowledging satisfaction
and discharge of this Indenture only if requested to do so with respect to
Securities of all series as to which it is Trustee and if the other conditions
thereto are met. In the event there are two or more Trustees hereunder, then the
effectiveness of any such instrument shall be conditioned upon receipt of such
instruments from all Trustees hereunder.

          Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Corporation to the Trustee under Section 6.7, the obligations
of the Trustee to any Authenticating Agent under Section 6.14 and, if money
shall have been deposited with the Trustee pursuant to subclause (ii) of clause
(a) of this Section, the obligations of the Trustee under Sections 3.5, 3.6,
4.2, 10.2 and 10.3 shall survive.

          Section 4.2 Application of Trust Money. Subject to the provision of
the last paragraph of Section 10.3, all money deposited with the Trustee
pursuant to Section 4.1 shall be held in trust and applied by it, in accordance
with the provisions of the Securities, the coupons and this Indenture, to the
payment, either directly or through any Paying Agent (including the Corporation
acting as its own Paying Agent) as the Trustee may determine, to the Persons
entitled thereto, of the principal (and premium, if any) and interest for whose
payment such money has been deposited with the Trustee, but such money need not
be segregated from other funds, except to the extent required by law.

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

          (a)  the Corporation defaults in the payment of any interest
(including any additional amounts due under Section 10.6 as specified therein)
upon any Security of that series when it becomes due and payable and continuance
of such default for a period of 30 days; or

                                       30

<PAGE>

          (b)  the Corporation defaults in the payment of the principal
(including any additional amounts due under Section 10.6 as specified therein)
of (or premium, if any, on) any Security of that series at its Maturity; or

          (c)  the Corporation defaults in the deposit of any sinking fund
payment when and as due by the terms of a Security of that series; or

          (d)  the Corporation defaults in the performance or breach of any
covenant or warranty of the Corporation in this Indenture (other than a covenant
or warranty a default in whose performance or whose breach is elsewhere in this
Section specifically dealt with or which has expressly been included in or
pursuant to this Indenture solely for the benefit of one or more series of
Securities other than that series), and continuance of such default or breach
for a period of 60 days after there has been given, by registered or certified
mail, to the Corporation by the Trustee, or to the Corporation 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; or

          (e)  a default under any bond, debenture, note or other evidence of
indebtedness for money borrowed by the Corporation (including a default with
respect to Securities of any series other than that series) or under any
mortgage, indenture or instrument under which there may be issued or by which
there may be secured or evidenced any indebtedness for money borrowed by the
Corporation (including this Indenture), whether such indebtedness now exists or
shall hereafter be created, which default shall constitute a failure to pay in
excess of $25,000,000 of the principal or interest of such indebtedness when due
and payable after the expiration of any applicable grace period with respect
thereto or shall have resulted in such indebtedness in an amount in excess of
$25,000,000 becoming or being declared due and payable prior to the date on
which it would otherwise have become due and payable, without such indebtedness
having been discharged or such acceleration having been rescinded or annulled
within a period of 30 days after there shall have been given, by registered or
certified mail, to the Corporation by the Trustee or to the Corporation and the
Trustee by the Holders of at least 25% in principal amount of the Outstanding
Securities of that series a written notice specifying such default and requiring
the Corporation to cause such indebtedness to be discharged or cause such
acceleration to be rescinded or annulled and stating that such notice is a
"Notice of Default" hereunder; provided, that subject to the provisions of
Sections 6.1 and 6.2, the Trustee shall not be deemed to have knowledge of such
default unless either (a) a Responsible Officer of the Trustee assigned to
[Institutional Trust Services] (or any successor division or department of the
Trustee) shall have actual knowledge of such default or (b) the Trustee shall
have received written notice thereof from the Corporation, from any Holder, from
the holder of any such indebtedness or from the trustee under any such mortgage
indenture or other instrument; or

          (f)  the entry by a court having jurisdiction in the premises of (a) a
decree or order for relief in respect of the Corporation in an involuntary case
or proceeding under any applicable federal or state bankruptcy, insolvency,
reorganization or other similar law or (b) a decree or order adjudging the
Corporation bankrupt or insolvent, or approving as properly filed a petition by
one or more Persons other than the Corporation or any Affiliates thereof seeking
reorganization, arrangement, adjustment or composition of or in respect of the
Corporation under

                                       31

<PAGE>

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

          (g)  the commencement by the Corporation of a case or proceeding under
any applicable federal or state bankruptcy, insolvency, reorganization or other
similar law or of any other case or proceeding to be adjudicated a bankrupt or
insolvent, or the consent by it to the entry of a decree or order for relief in
respect of it in a case or proceeding under any applicable federal or state
bankruptcy, insolvency, reorganization or other similar law or to the
commencement of any bankruptcy or insolvency case or proceeding against it, or
the filing by it of a petition or answer or consent seeking reorganization or
relief under any applicable federal or state law, or the consent by it to the
filing of such petition or to the appointment of or taking possession by a
custodian, receiver, liquidator, assignee, trustee, sequestrator or similar
official in respect of it or any substantial part of its property, or the making
by it of an assignment for the benefit of creditors, or its admission in writing
of its inability to pay its debts generally as they become due, or its taking of
corporate action in furtherance of any such action; or

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

          Section 5.2 Acceleration of Maturity; Rescission and Annulment. If an
Event of Default with respect to Securities of any series at the time
Outstanding occurs and is continuing, then in every such case the Trustee or the
Holders of not less than 25% in principal amount of the Outstanding Securities
of that series may declare the principal amount (or, if the Securities of that
series are Original Issue Discount Securities, such portion of the principal
amount as may be specified in the terms of that series) of all of the Securities
of that series to be due and payable immediately, by a notice in writing to the
Corporation (and to the Trustee if given by Holders), and upon any such
declaration such principal amount (or specified amount) shall become 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 judgment or decree for
payment of the money due has been obtained by the Trustee as hereinafter in this
Article provided, the Holders of a majority in principal amount of the
Outstanding Securities of that series, by written notice to the Corporation and
the Trustee, may rescind and annul such declaration and its consequences if:

          (a)  the Corporation has paid or deposited with the Trustee a sum
sufficient to pay:

               (i)   all overdue interest on all Securities of that series;

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

                                       32

<PAGE>

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

               (iv)  all sums paid or advanced by the Trustee hereunder and the
     reasonable compensation, expenses, disbursements and advances of the
     Trustee, its agents and counsel, and any other amounts due to the Trustee
     under Section 6.7;

          and

          (b)  all 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 5.13.

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

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

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

          (b)  default is made in the payment of the principal of (or premium,
if any, on) any Security at the Maturity thereof and such default continues for
a period of three Business Days,

the Corporation shall, upon demand of the Trustee, pay to it, for the benefit of
the Holders of such Securities and coupons, the whole amount then due and
payable on such Securities and coupons for principal (and premium, if any) and
interest, if any, with interest on any overdue principal (and premium, if any)
and on any overdue interest, to the extent that payment of such interest shall
be legally enforceable, at the rate or rates prescribed therefor in such
Securities, and, in addition thereto, such further amount as shall be sufficient
to cover the costs and expenses of collection, including the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel, and any other amounts due to the Trustee under Section 6.7.

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

          If an Event of Default with respect to Securities of any series occurs
and is continuing, the Trustee may in its discretion proceed to protect and
enforce its rights and the rights of the Holders of Securities of such series
and any related coupons by such appropriate judicial proceedings as the Trustee
shall deem most effectual to protect and enforce any such

                                       33

<PAGE>

rights, whether for the specific enforcement of any covenant or agreement in
this Indenture, or in aid of the exercise of any power granted herein, or to
enforce any other proper remedy.

          Section 5.4 Trustee May File Proofs of Claim. In case of the pendency
of any receivership, insolvency, liquidation, bankruptcy, reorganization,
arrangement, adjustment, composition or other judicial proceeding relative to
the Corporation or any other obligor upon the Securities or the property of the
Corporation or of such other obligor or their creditors, the Trustee
(irrespective of whether the principal of the Securities shall then be due and
payable as therein expressed or by declaration or otherwise and irrespective of
whether the Trustee shall have made any demand on the Corporation or any other
obligor for the payment of overdue principal or interest) shall be entitled and
empowered, by intervention in such proceeding or otherwise:

          (a)  to file and prove a claim for the whole amount of principal (and
premium, if any) and interest owing and unpaid in respect of the Securities and
to file such other papers or documents as may be necessary or advisable in order
to have the claims of the Trustee (including any claim for the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel, and any other amounts due to the Trustee under Section 6.7) and of
the Holders of Securities and coupons allowed in such judicial proceeding; and

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

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or
other similar official in any such judicial proceeding is hereby authorized by
each Holder of Securities and coupons to make such payments to the Trustee and,
in the event that the Trustee shall consent to the making of such payments
directly to the Holders of Securities and coupons, to pay to the Trustee any
amount due it for the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel, and any other amounts due the
Trustee under Section 6.7.

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

          Section 5.5 Trustee May Enforce Claims Without Possession of
Securities or Coupons. All rights of action and claims under this Indenture or
the Securities or coupons may be prosecuted and enforced by the Trustee without
the possession of any of the Securities or coupons or the production thereof in
any proceeding relating thereto, and any such proceeding instituted by the
Trustee shall be brought in its own name as trustee of an express trust, and any
recovery of judgment shall, after provision for the payment of the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel, be for the ratable benefit of the Holders of the Securities and
coupons in respect of which such judgment has been recovered.

                                       34

<PAGE>

          Section 5.6 Application of Money Collected. Any money collected by the
Trustee pursuant to this Article shall be applied in the following order, at the
date or dates fixed by the Trustee and, in case of the distribution of such
money on account of principal (or premium, if any) or interest, if any, upon
presentation of the Securities or coupons, or both, as the case may be, and the
notation thereon of the payment if only partially paid and upon surrender
thereof if fully paid:

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

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

          THIRD: To the Corporation.

          Section 5.7 Limitation on Suits. No Holder of any Security of any
series or any related coupons shall have any right to institute any proceeding,
judicial or otherwise with respect to this Indenture, or for the appointment of
a receiver or trustee, or for any other remedy hereunder, unless:

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

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

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

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

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

it being understood and intended that no one or more of such Holders shall have
any right in any manner whatever by virtue of, or by availing of, any provision
of this Indenture to affect, disturb or prejudice the rights of any other 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 5.8 Unconditional Right of Holders to Receive Principal,
Premium and Interest. Notwithstanding any other provision in this Indenture, the
Holder of any Security or coupon shall have the right, which is absolute and
unconditional, to receive payment of the

                                       35

<PAGE>

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

          Section 5.9 Restoration of Rights and Remedies. If the Trustee or any
Holder of a Security or coupon 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 Corporation, the Trustee and the Holders of Securities and
coupons shall be restored severally and respectively to their former positions
hereunder and thereafter all rights and remedies of the Trustee and the Holders
shall continue as though no such proceeding had been instituted.

          Section 5.10 Rights and Remedies Cumulative. Except as otherwise
provided with respect to the replacement or payment of mutilated, destroyed,
lost or stolen Securities or coupons in the last paragraph of Section 3.6, no
right or remedy herein conferred upon or reserved to the Trustee or to the
Holders of Securities or coupons is intended to be exclusive of any other right
or remedy, and every right and remedy shall, to the extent permitted by law, be
cumulative and in addition to every other right and remedy given hereunder or
now or hereafter existing at law or in equity or otherwise. The assertion or
employment of any right or remedy hereunder, or otherwise shall, not prevent the
concurrent assertion or employment of any other appropriate right or remedy.

          Section 5.11 Delay or Omission Not Waiver. No delay or omission of the
Trustee or of any Holder of any Security or coupon to exercise any right or
remedy accruing upon any Event of Default shall impair any such right or remedy
or constitute a waiver of any such Event of Default or an acquiescence therein.
Every right and remedy given by this Article or by law to the Trustee or to the
Holders of Securities or coupons may be exercised from time to time, and as
often as may be deemed expedient, by the Trustee or by the Holders of Securities
or coupons, as the case may be.

          Section 5.12 Control by Holders of Securities. The Holders of a
majority in principal amount of the Outstanding Securities of any series shall
have the right to direct the time, method and place of conducting any proceeding
for any remedy available to the Trustee, or exercising any trust or power
conferred on the Trustee, with respect to the Securities of such series;
provided, that:

          (a)  such direction shall not be in conflict with any rule of law or
with this Indenture, expose the Trustee to personal liability or be unduly
prejudicial to Holders not joined therein; and

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

                                       36

<PAGE>

          Section 5.13 Waiver of Past Defaults. The Holders of not less than a
majority in principal amount of the Outstanding Securities of any series may on
behalf of the Holders of all the Securities of such series and any related
coupons waive any past default hereunder with respect to such series and its
consequences, except a default:

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

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

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

          Section 5.14 Undertaking for Costs. All parties to this Indenture
agree, and each Holder of any Security or coupon by his acceptance thereof shall
be deemed to have agreed, that any court may in its discretion require, in any
suit for the enforcement of any right or remedy under this Indenture, or in any
suit against the Trustee for any action taken, suffered or omitted by it as
Trustee, the filing by any party litigant in such suit of an undertaking to pay
the costs of such suit, and that such court may in its discretion assess
reasonable costs, including reasonable attorneys' fees, against any party
litigant in such suit, having due regard to the merits and good faith of the
claims or defenses made by such party litigant; but the provisions of this
Section shall not apply to any suit instituted by the Trustee, to any suit
instituted by any Holder, or group of Holders, holding in the aggregate more
than 10% in principal amount of the Outstanding Securities of any series, or to
any suit instituted by any Holder of any Security or coupon for the enforcement
of the payment of the principal of (or premium, if any) or interest, if any, on
any Security or the payment of any coupon on or after the Stated Maturity or
Maturities expressed in such Security (or, in the case of redemption, on or
after the Redemption Date).

          Section 5.15 Waiver of Stay or Extension Laws. The Corporation
covenants (to the extent that it may lawfully do so) that it shall not at any
time insist upon, or plead, or in any manner whatsoever claim or take the
benefit or advantage of, any stay or extension law wherever enacted, now or at
any time hereafter in force which may affect the covenants or the performance of
this Indenture; and the Corporation (to the extent that it may lawfully do so)
hereby expressly waives all benefit or advantage of any such law and covenants
that it shall not hinder, delay or impede the execution of any power herein
granted to the Trustee, but shall suffer and permit the execution of every such
power as though no such law had been enacted.

                                       37

<PAGE>

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

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

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

          (b)  In case an Event of Default with respect to 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 use the same degree of care and skill in their exercise, as a
prudent man would exercise or use under the circumstances in the conduct of his
own affairs.

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

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

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

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

               (iv)  no provision of this Indenture shall require the Trustee to
     expend or risk its own funds or otherwise incur any financial liability in
     the performance of any of its duties hereunder, or in the exercise of any
     of its rights or powers, if it shall have reasonable grounds for believing
     that repayment of such funds or adequate indemnity against such risk or
     liability is not reasonably assured to it.

                                       38

<PAGE>

          (d)  Whether or not therein expressly so provided, every provision of
this Indenture relating to the conduct or affecting the liability of or
affording protection to the Trustee shall be subject to the provisions of this
Section.

          Section 6.2 Notice of Defaults. Within 90 days after the occurrence of
any default hereunder with respect to the Securities of any series, the Trustee
shall transmit, in the manner and to the extent provided in Section 313(c) of
the Trust Indenture Act, notice of all such defaults hereunder known to the
Trustee, unless such default shall have been cured or waived; provided, that
except in the case of a default in the payment of the principal of (or premium,
if any) or interest, if any, on any Security of such series or in the payment of
any sinking fund installment with respect to Securities of such series, the
Trustee shall be protected in withholding such notice if and so long as the
board of directors, the executive committee or a committee of directors or
Responsible Officers of the Trustee in good faith determine that the withholding
of such notice is in the interest of the Holders of Securities of such series;
and provided further, that in the case of any default of the character specified
in Section 5.1(d) with respect to Securities of such series, no such notice to
Holders shall be given until at least 30 days after the occurrence thereof. For
the purpose of this Section, the term "default" means any event which is, or
after notice or lapse of time or both would become, an Event of Default with
respect to Securities of such series.

          Section 6.3 Certain Rights of Trustee. Subject to Sections 315(a)
through 315(d) of the Trust Indenture Act:

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

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

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

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

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

                                       39

<PAGE>

          (f)  the Trustee shall not be bound to make any investigation into the
facts or matters stated in any resolution, certificate, statement, instrument,
opinion, report, notice, request, direction, consent, order, bond, debenture,
note, coupon, other evidence of indebtedness or other paper or document, but the
Trustee, in its discretion, may make such further inquiry or investigation into
such facts or matters as it may see fit, and, if the Trustee shall determine to

          (h)  except as otherwise provided in Section 501(e), the Trustee
shall not be charged with knowledge of any Event of Default with respect to the
Securities of any series for which it is acting as Trustee unless either (a) a
Responsible Officer of the Trustee assigned to its Institutional Trust Services
unit (or any successor division or department of the Trustee) shall have actual
knowledge of the Event of Default or (b) written notice of such Event of Default
shall have been given to the Trustee by the Corporation, any other obligor on
such Securities or by any Holder of such Securities.

          Section 6.4 Not Responsible for Recitals or Issuance of Securities.
The recitals contained herein and in the Securities (except the Trustee's
certificates of authentication) and in any coupons shall be taken as the
statements of the Corporation, and the Trustee or any Authenticating Agent
assumes no responsibility for their correctness. The Trustee makes no
representations as to the validity or sufficiency of this Indenture or of the
Securities or coupons, except that the Trustee represents that it is duly
authorized to execute and deliver this Indenture, authenticate the Securities
and perform its obligations hereunder and that the statements made by it in a
Statement of Eligibility and Qualification on Form T-1 supplied to the
Corporation are true and accurate, subject to the qualifications set forth
therein. The Trustee or any Authenticating Agent shall not be accountable for

pledgee of Securities and coupons and, subject to Sections 310(b) and 311 of the
Trust Indenture Act, may otherwise deal with the Corporation or an Affiliate
thereof with the same rights it would have if it were not Trustee,
Authenticating Agent, Paying Agent, Security Registrar or such other agent.

          Section 6.6 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 Corporation.

          Section 6.7 Compensation and Reimbursement. The Corporation agrees:

                                       40

<PAGE>

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

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

          (c) to indemnify, defend and hold harmless the Trustee and its
directors, employees, Affiliates and agents ("indemnitees") for, and to hold
them harmless against, any loss, liability or expense (including the fees and
expenses of counsel) arising out of or incurred in connection with (i) the
acceptance or administration of the trust or trusts hereunder, except to the
extent with respect to any indemnitee that such loss, liability or expense was
due to such indemnitee's negligence, willful misconduct or bad faith, and (ii)
any action taken, suffered or omitted upon the Order of the Corporation.

          As security for the performance of the obligations of the Corporation
under this Section, the Trustee shall have a lien prior to the Securities upon
all property and funds held or collected by the Trustee as such, except funds
held in trust for the payment of principal of, premium, if any, or interest, if
any, on particular Securities. The obligations of the Corporation under this
Section shall survive the discharge of this Indenture and the succession of the
Trustee hereunder.

          Section 6.8 Disqualification; Conflicting Interests. If at any time
the Trustee fails to comply with the obligations imposed upon it by the
provisions of Section 310(b) of the Trust Indenture Act with respect to
Securities of any series after written request therefor by the Corporation or by
any Holder of a Security of such series who has been a bona fide Holder of a
Security of such series for at least six months then, (1) the Corporation, by or
pursuant to a Board Resolution, may remove the Trustee with respect to all
Securities or the Securities of such series, or (2) 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 removal of the Trustee with respect to all Securities of such series and the
appointment of a successor Trustee or Trustees. The Trustee shall comply with
the terms of Section 310(b) of the Trust Indenture Act.

          Section 6.9 Corporate Trustee Required; Eligibility. There shall at
all times be a Trustee hereunder that is a Person organized and doing business
under the laws of the United States of America, any state thereof or the
District of Columbia, authorized under such laws to exercise corporate trust
powers, or any other Person permitted by the Trust Indenture Act to act as
trustee under an indenture qualified under the Trust Indenture Act and that has
a combined capital and surplus (computed in accordance with Section 310(a)(2) of
the Trust Indenture Act) of at least $50,000,000, is subject to supervision or
examination by federal, state or District of Columbia authority and is not
otherwise ineligible under Section 310(a)(5) of the Trust Indenture Act. If such
Person publishes reports of condition at least annually, pursuant to law or to
the requirements of said supervising or examining authority, then for the
purposes of this Section, the combined capital and surplus of such Person 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

                                       41

<PAGE>

ceases to be eligible in accordance with the provisions of this Section, it
shall resign immediately in the manner and with the effect hereinafter specified
in this Article.

          Section 6.10 Resignation and Removal; Appointment of Successor.

          (a)  No resignation or removal of the Trustee and no appointment of a
successor Trustee pursuant to this Article shall become effective until the
acceptance of appointment by the successor Trustee in accordance with the
applicable requirements of Section 6.11.

          (b)  The Trustee may resign at any time with respect to the Securities
of one or more series by giving written notice thereof to the Corporation. If
the instrument of acceptance by a successor Trustee required by Section 6.11 is
not delivered to the Trustee within 30 days after the giving of such notice of
resignation, the resigning Trustee may petition any court of competent
jurisdiction for the appointment of a successor Trustee with respect to the
Securities of such series.

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

          (d)  If at any time:

               (1)  the Trustee fails to comply with Section 6.8 after written
     request therefor by the Corporation or by any Holder of a Security who has
     been a bona fide Holder of a Security for at least six months; or

               (2)  the Trustee ceases to be eligible under Section 6.9 and
     fails to resign after written request therefor by the Corporation or by any
     such Holder; or

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

then, in any such case, (i) the Corporation by Board Resolution may remove the
Trustee with respect to all Securities, or (ii) subject to Section 315(e) of the
Trust Indenture Act, any Holder of a Security who has been a bona fide Holder of
a Security for at least six months may, on behalf of himself and all other
similarly situated Holders, 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, is removed or becomes incapable of
acting, or if a vacancy occurs in the office of Trustee for any cause, with
respect to the Securities of one or more series, the Corporation, by a Board
Resolution, shall promptly appoint a successor Trustee or Trustees with respect
to the Securities of that or those series (it being understood that any such
successor Trustee may be appointed with respect to the Securities of one or more
or all of such series and that at any time there shall be only one Trustee with
respect to the Securities of any

                                       42

<PAGE>

particular series) and shall comply with the applicable requirements of Section
6.11. If, within one year after such resignation, removal or incapability, or
the occurrence of such vacancy, a successor Trustee with respect to the
Securities of any series is appointed by Act of the Holders of a majority in
principal amount of the Outstanding Securities of such series delivered to the
Corporation 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 6.11, become the successor Trustee with
respect to the Securities of such series and to that extent supersede the
successor Trustee appointed by the Corporation. If no successor Trustee with
respect to the Securities of any series is so appointed by the Corporation or
the Holders of Securities and accepts appointment in the manner required by
Section 6.11, any Holder of a Security who has been a bona fide Holder of a
Security of such series for at least six months may, on behalf of himself and
all others similarly situated, petition any court of competent jurisdiction for
the appointment of a successor Trustee with respect to the Securities of such
series.

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

          Section 6.11 Acceptance of Appointment by Successor.

          (a)  In case of the appointment hereunder of a successor Trustee with
respect to all Securities, every such successor Trustee so appointed shall
execute, acknowledge and deliver to the Corporation and to the retiring Trustee
an instrument accepting such appointment. Thereupon the resignation or removal
of the retiring Trustee shall become effective and such successor Trustee,
without any further act, deed or conveyance shall become vested with all the
rights, powers, trusts and duties of the retiring Trustee; but, on the request
of the Corporation 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; provided, that such property
and money shall continue to be subject to any lien in favor of the retiring
Trustee provided for in Section 6.7.

          (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 Corporation,
the retiring Trustee and each successor Trustee with respect to the Securities
of one or more series shall execute and deliver an indenture supplemental hereto
wherein each successor Trustee shall accept such appointment and which (1) shall
contain such provisions as shall be necessary or desirable to transfer and
confirm to, and to vest in, each successor Trustee all the rights, powers,
trusts and duties of the retiring Trustee with respect to the Securities of that
or those series to which the appointment of such

                                       43

<PAGE>

successor Trustee relates, (2) if the retiring Trustee is not retiring with
respect to all Securities, shall contain such provisions as shall be deemed
necessary or desirable to confirm that all the rights, powers, trusts and duties
of the retiring Trustee with respect to the Securities of that or those series
as to which the retiring Trustee is not retiring shall continue to be vested in
the retiring Trustee, and (3) shall add to or change any of the provisions of
this Indenture as shall be necessary to provide for or facilitate the
administration of the trusts hereunder by more than one Trustee, it being
understood that nothing herein or in such supplemental indenture shall
constitute such Trustees co-trustees of the same trust and that each such
Trustee shall be trustee of a trust or trusts hereunder separate and apart from
any trust or trusts hereunder administered by any other such Trustee; and upon
the execution and delivery of such supplemental indenture the resignation or
removal of the retiring Trustee shall become effective to the extent provided
therein and each such successor Trustee, without any further act, deed or
conveyance, shall become vested with all the rights, powers, trusts and duties
of the retiring Trustee with respect to the Securities of that or those series
to which the appointment of such successor Trustee relates; but, on request of
the Corporation 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, subject nevertheless to its lien
provided for in Section 6.7, 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 Corporation shall
execute any and all instruments for more fully and certainly vesting in and
confirming to such successor Trustee all such rights, powers and trusts referred
to in paragraph (a) or (b) of this Section, as the case may be.

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

          Section 6.12 Merger, Conversion, Consolidation or Succession to
Business. Any Person into which the Trustee may be merged or converted or with
which it may be consolidated, or any Person resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any Person
succeeding to all or substantially all the corporate trust business of the
Trustee, shall be the successor of the Trustee hereunder, if such Person is
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 Preferential Collection of Claims Against Corporation. If
and when the Trustee is or becomes a creditor of the Corporation (or any other
obligor upon the Securities), the Trustee shall be subject to the provisions of
Section 311 and any other provision of the Trust Indenture Act regarding the
collection of claims against the Corporation (or any such other obligor), as the
case may be.

                                       44

<PAGE>

          Section 6.14 Appointment of Authenticating Agent. At any time when any
of the Securities remain Outstanding, the Trustee may appoint an Authenticating
Agent or Agents with respect to one or more series of Securities which shall be
authorized to act on behalf of the Trustee to authenticate Securities of such
series issued upon exchange, registration of transfer or partial redemption
thereof or pursuant to Section 3.6, 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. 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 Corporation and shall at all times be a corporation organized
and doing business under the laws of the United States of America, any state
thereof or the District of Columbia, authorized under such laws to act as
Authenticating Agent, having a combined capital and surplus (computed in
accordance with Section 310(a)(2) of the Trust Indenture Act) of not less than
$50,000,000 and subject to supervision or examination by federal, state or
District of Columbia authority. If such corporation publishes reports of
condition at least annually, pursuant to law or to the requirements of said
supervising or examining authority, then for the purposes of this Section, the
combined capital and surplus of such corporation shall be deemed to be its
combined capital and surplus as set forth in its most recent report of condition
so published. If at any time an Authenticating Agent ceases 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, if such corporation is otherwise eligible under this
Section, without the execution or filing of any paper or any further act on the
part of the Trustee or the Authenticating Agent.

          An Authenticating Agent may resign at any time by giving written
notice thereof to the Trustee and to the Corporation. The Trustee may at any
time terminate the agency of an Authenticating Agent by giving written notice
thereof to such Authenticating Agent and to the Corporation. Upon receiving such
a notice of resignation or upon such termination, or in case at any time such
Authenticating Agent ceases to be eligible in accordance with the provisions of
this Section, the Trustee may appoint a successor Authenticating Agent which
shall be acceptable to the Corporation and shall (1) mail written notice of such
appointment by first-class mail, postage prepaid, to all Holders of Registered
Securities, if any, of the series with respect to which such Authenticating
Agent shall serve, as their names and addresses appear in the Security Register,
and (2) if Securities of the series are issuable as Bearer Securities, publish
notice of such appointment at least once in an Authorized Newspaper in the place
where such successor Authenticating Agent has its principal office if such
office is located outside the United States. 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

                                       45

<PAGE>

originally named as an Authenticating Agent. No successor Authenticating Agent
shall be appointed unless eligible under the provisions of this Section.

          The provisions of Sections 3.8, 6.4 and 6.5 shall be applicable to
each Authenticating Agent.

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

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

any provisions to or changing in any manner or eliminating any of the provisions
of this Indenture or modifying in any manner the rights of the Holders of
Securities of such series and any related coupons under this Indenture;
provided, that no such supplemental indenture shall, without the consent of the
Holder of each Outstanding Security or coupon affected thereby:

coupon with respect to changes in the references to "the Trustee" and
concomitant changes in this Section and Section 10.4, or the deletion of this
proviso, in accordance with the requirements of Sections 6.11(b) and 9.1(h).

A supplemental indenture which changes or eliminates any covenant or other
provision of this Indenture which has expressly been included solely for the
benefit of one or more particular series of 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.

                                       50

<PAGE>

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

     The Corporation shall have the right to set a record date for the
solicitation of any consents under this Article Nine, which record date shall be
set in accordance with Section 1.4.

     Section 9.3 Execution of Supplemental Indentures. In executing, or
accepting the additional trusts created by, any supplemental indenture permitted
by this Article or the modifications thereby of the trusts created by this
Indenture, the Trustee shall be entitled to receive, and (subject to Section 315
of the Trust Indenture Act) shall be fully protected in relying upon, an Opinion
of Counsel stating that the execution of such supplemental indenture is
authorized or permitted by this Indenture. The Trustee may, but shall not be
obligated to, enter into any such supplemental indenture which affects the
Trustee's own rights, duties, immunities or liabilities under this Indenture or
otherwise.

     Section 9.4 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 coupons appertaining
thereto shall be bound thereby.

     Section 9.5 Conformity with Trust Indenture Act. Every supplemental
indenture executed pursuant to this Article shall conform to the requirements of
the Trust Indenture Act as then in effect.

     Section 9.6 Reference in Securities to Supplemental Indentures. Securities
of any series authenticated and delivered after the execution of any
supplemental indenture pursuant to this Article may, and shall if required by
the Trustee, bear a notation in form approved by the Trustee as to any matter
provided for in such supplemental indenture. If the Corporation shall so
determine, new Securities of any series so modified as to conform, in the
opinion of the Trustee and the Corporation, to any such supplemental indenture
may be prepared and executed by the Corporation and authenticated and delivered
by the Trustee in exchange for Outstanding Securities of such series.

                                   ARTICLE TEN

                                    Covenants

     Section 10.1 Payment of Principal, Premium and Interest. The Corporation
covenants and agrees for the benefit of each series of Securities that it shall
duly and punctually pay the principal of (and premium, if any) and interest
(including any Additional Interest), if any, on the Securities of that series in
accordance with the terms of such Securities and this Indenture.

     Section 10.2 Maintenance of Office or Agency. The Corporation shall
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 demands to or upon

                                       51

<PAGE>

the Corporation in respect of the Securities of that series and this Indenture
may be served. The Corporation initially appoints the Trustee, acting through
its Corporate Trust Office, as its agent for said purposes. The Corporation
shall give prompt written notice to the Trustee of any change in the location of
any such office or agency. If at any time the Corporation fails to maintain such
office or agency or fails 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 Corporation hereby appoints the
Trustee as its agent to receive all such presentations, surrenders, notices and
demands.

     The Corporation may also from time to time designate one or more other
offices or agencies where the Securities may be presented or surrendered for any
or all of 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 Corporation of its obligation to maintain an office or agency in
each Place of Payment for Securities of any series for such purposes. The
Corporation shall give prompt written notice to the Trustee of any such
designation and any change in the location of any such office or agency.

     Section 10.3 Money for Securities Payments to be Held in Trust. If the
Corporation at any time acts as its own Paying Agent with respect to any series
of Securities, it shall, on or before each due date of the principal of (and
premium, if any) or interest (including any Additional Interest) on any of the
Securities of such series, segregate and hold in trust for the benefit of the
Persons entitled thereto a sum sufficient to pay the principal (and premium, if
any) or interest (including any Additional Interest), if any, so becoming due
until such sums shall be paid to such Persons or otherwise disposed of as herein
provided, and shall promptly notify the Trustee of its failure so to act.

     Whenever the Corporation shall have one or more Paying Agents, it shall,
prior to 10:00 a.m., New York City time, on each due date of the principal of
(or premium, if any) or interest (including any Additional Interest), if any, on
any Securities, deposit with a Paying Agent a sum sufficient to pay the
principal (and premium, if any) or interest (including any Additional Interest),
if any, so becoming due, such sum to be held in trust for the benefit of the
Persons entitled to such principal (and premium, if any) or interest (including
any Additional Interest), if any, and if the Corporation fails to make such
deposit (unless such Paying Agent is the Trustee) the Corporation shall promptly
notify the Trustee of its failure so to act.

     The Corporation shall cause each Paying Agent 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 shall:

     (a) hold all sums held by it for the payment of the principal of (and
premium, if any) or interest (including any Additional Interest), if any, on the
Securities of a 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;

     (b) give the Trustee notice of any default by the Corporation (or any other
obligor upon such Securities) in the making of any payment of principal (and
premium, if any) or interest (including any Additional Interest), if any, in
respect of any Security of any series;

                                       52

<PAGE>

     (c) at any time during the continuance of any default with respect to a
series of Securities, upon the written request of the Trustee, forthwith pay to
the Trustee all sums so held in trust by such Paying Agent with respect to such
series; and

     (d) comply with the provisions of the Trust Indenture Act applicable to it
as a Paying Agent.

     The Corporation may at any time, for the purpose of obtaining the
satisfaction and discharge of this Indenture or for any other purpose, pay, or
by an Order of the Corporation direct any Paying Agent to pay, to the Trustee
all sums held in trust by the Corporation 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 Corporation 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 Corporation in trust for the payment of the principal of (and premium, if
any) or interest (including any Additional Interest), if any, on any Security
and remaining unclaimed for two years after such principal (and premium, if any)
or interest (including any Additional Interest), if any, has become due and
payable shall (unless otherwise required by mandatory provision of applicable
escheat or abandoned or unclaimed property law) be paid on Request of the
Corporation, or (if then held by the Corporation) shall (unless otherwise
required by mandatory provision of applicable escheat or abandoned or unclaimed
property law) be discharged from such trust; and the Holder of such Security
shall thereafter, as an unsecured general creditor, look only to the Corporation
for payment thereof, and all liability of the Trustee or such Paying Agent with
respect to such trust money, and all liability of the Corporation 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 Corporation 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 Borough of Manhattan, The City of New York, 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 shall be repaid to the
Corporation.

     Section 10.4 Statement as to Compliance. The Corporation shall deliver to
the Trustee, within 120 days after the end of each fiscal year of the
Corporation ending after the date hereof, an Officers' Certificate covering the
preceding calendar year, stating whether or not to the best knowledge of the
signers thereof the Corporation is in default in the performance, observance or
fulfillment of or compliance with any of the terms, provisions, covenants and
conditions of this Indenture, and if the Corporation is in default, specifying
all such defaults and the nature and status thereof of which they may have
knowledge. For the purpose of this Section 10.4, compliance shall be determined
without regard to any grace period or requirement of notice provided pursuant to
the terms of this Indenture.

     Section 10.5 Waiver of Certain Covenants. The Corporation may omit in any
particular instance to comply with any covenant or condition provided pursuant
to Section 3.1, 9.1(b) or 9.1(g) with respect to the Securities of any series,
if before or after the time for such

                                       53

<PAGE>

compliance the Holders of at least a majority in aggregate principal amount of
the Outstanding Securities of such series shall, by Act of such Holders, either
waive such compliance in such instance or generally waive compliance with such
covenant or condition, but no such waiver shall extend to or affect such
covenant or condition except to the extent so expressly waived, and, until such
waiver shall become effective, the obligations of the Corporation in respect of
any such covenant or condition shall remain in full force and effect.

     Section 10.6 Additional Sums. If the Securities of a series provide for the
payment of additional amounts, the Corporation shall pay to the Holder of any
Security of any series or any coupon appertaining hereto additional amounts upon
the terms and subject to the conditions provided therein. Whenever in this
Indenture there is mentioned, in any contexts, the payment of the principal of
(or premium, if any) or interest, if any, on, or in respect of, any Security of
any series or any related coupon or the net proceeds received on the sale or
exchange of any Security of any series, such mention shall be deemed to include
mention of the payment of additional amounts provided for in the terms of such
Securities and this Section to the extent that, in such context, additional
amounts are, were or would be payable in respect thereof pursuant to the
provisions of this Section, and express mention of the payment of any additional
amounts (if applicable) in any provisions hereof shall not be construed as
excluding additional amounts in those provisions hereof where express mention is
not made.

     If the Securities of a series provide for the payment of additional
amounts, at least 10 days prior to the first Interest Payment Date with respect
to that series of Securities (or if the Securities of that series shall not bear
interest prior to Maturity, the first day on which a payment of principal (and
premium, if any) is made), and at least 10 days prior to each date of payment of
principal (and premium, if any) or interest if there has been any change with
respect to the matters set forth in the above-mentioned Officers' Certificate,
the Corporation shall furnish to the Trustee and the Corporation's principal
Paying Agent or Paying Agents, if other than the Trustee, an Order instructing
the Trustee and such Paying Agent or Paying Agents whether such payment of
principal of (and premium, if any) or interest on the Securities of that series
shall be made to Holders of Securities of that series or the related coupons who
are United States Aliens without withholding for or on account of any tax,
assessment or other governmental charge described in the Securities of that
series. If any such withholding shall be required, then such Order shall specify
by country the amount, if any, required to be withheld on such payments to such
Holders of Securities or coupons, and the Corporation shall pay to the Trustee
or such Paying Agent the additional amounts, if any, required by the terms of
such Securities and the first paragraph of this Section. The Corporation shall
indemnify, defend and hold harmless the Trustee and any Paying Agent and any
director, employee, Affiliate or agent of either (a "Section 10.6 Indemnitee")
against any loss, liability or expense, including without limitation any
penalties and the fees and expenses of counsel, arising out of or in connection
with actions taken or omitted in reliance on any Order furnished pursuant to
this Section, except to the extent with respect to any Section 10.6 Indemnitee
any loss, liability or expense is due to the negligence, willful misconduct or
bad faith of such Section 10.6 Indemnitee.

     Section 10.7 Original Issue Discount. For each year during which any
Original Issue Discount Securities are Outstanding, the Corporation shall
furnish to each Paying Agent in a timely fashion such information as may be
reasonably requested by each Paying Agent in order that each Paying Agent may
prepare the information which it is required to report for such year on Internal
Revenue Service Forms 1096 and 1099 pursuant to Section 6049 of the Internal
Revenue Code of 1986, as amended. Such information shall include the amount of
original issue

                                       54

<PAGE>

discount includible in income for each $1,000 of principal amount at Stated
Maturity of outstanding Securities during such year.

     Section 10.8 Limitation on Disposition of Stock or Assets of the Bank. So
long as any Securities remain outstanding, but subject to the provisions of
Article Eight, the Corporation shall not sell, assign, transfer, grant a
security interest in or otherwise dispose of any shares of, securities
convertible into or options, warrants or rights to subscribe for or purchase
shares of, Voting Stock of the Bank or of any Subsidiary which owns Voting Stock
of the Bank, nor will it permit the Bank to issue any shares of, or securities
convertible into, or options, warrants or rights to subscribe for or purchase,
shares of, Voting Stock of the Bank or to sell, lease or otherwise dispose of
all or substantially all of its property, assets and business except that (a)
the Corporation or the Bank, as the case may be, may make any such sale,
assignment, transfer, grant of a security interest, lease or other disposition
for fair market value on the date thereof, as determined by the Board of
Directors of the Corporation (which determination shall be conclusive) and
evidenced by a duly adopted Board Resolution (provided, that if such
consideration includes securities of any Person, such Person would not be an
Affiliate of the Corporation immediately after the consummation of such
transaction), and (b) if, in the case of any sale, assignment, transfer, grant
of a security interest or other disposition of shares of, securities convertible
into or options, warrants or rights to subscribe for or purchase shares of
Voting Stock of the Bank or of any such Subsidiary, after giving effect thereto
(and assuming, for purposes of this clause (b), that all such convertible
securities have been fully converted and all such options, warrants or rights
have been fully exercised), the Corporation shall own at least 80% of the Voting
Stock of the Bank then issued and outstanding free and clear of any security
interest. Notwithstanding the foregoing, and subject to provisions of Article
Eight, the Corporation may merge, consolidate or combine with the Bank or the
Corporation and the Bank may merge, consolidate or combine with a third
corporation.

                                 ARTICLE ELEVEN

                            Redemption of Securities

     Section 11.1 Applicability of Article. Securities of any series that are
redeemable 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 11.2 Election to Redeem; Notice to Trustee. The election of the
Corporation to redeem any Securities shall be evidenced by a Board Resolution.
In case of any redemption at the election of the Corporation of all of the
Securities of any series, the Corporation shall, at least 60 days prior to the
Redemption Date fixed by the Corporation (unless a shorter notice shall be
satisfactory to the Trustee), notify the Trustee in writing of such Redemption
Date. In case of any redemption at the election of the Corporation of less than
all the Securities of any series, the Corporation shall, at least 60 days prior
to the Redemption Date fixed by the Corporation (unless a shorter notice shall
be satisfactory to the Trustee), notify the Trustee in writing of such
Redemption Date and of the principal amount of Securities of such series to be
redeemed. In the case of any redemption of Securities (1) prior to the
expiration of any restriction on such redemption provided in the terms of such
Securities or elsewhere in this

                                       55

<PAGE>

Indenture, or (2) pursuant to an election of the Corporation which is subject to
a condition specified in the terms of such Securities, the Corporation shall
furnish the Trustee with an Officers' Certificate evidencing compliance with
such restriction or condition.

     Section 11.3 Selection by Trustee of Securities to be Redeemed. If less
than all the Securities of any series are to be redeemed, the particular
Securities to be redeemed shall be selected not more than 60 days prior to the
Redemption Date by the Trustee from the Outstanding Securities of such series
(other than Securities of such series held by the Corporation), not previously
called for redemption, by such method as the Trustee shall deem fair and
appropriate and which may provide for the selection for redemption of portions
(equal to the minimum authorized denomination for Securities of that series or
any integral multiple thereof) of the principal amount of Securities of such
series of a denomination larger than the minimum authorized denomination for
Securities of that series. Unless otherwise provided in the Securities of a
series, partial redemptions must be in an amount not less than $1,000,000
principal amount of Securities.

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

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

     Section 11.4 Notice of Redemption. Notice of redemption shall be given in
the manner provided in Section 1.6 to the Holders of Securities to be redeemed
not less than 30 nor more than 60 days prior to the Redemption Date.

     All notices of redemption shall state:

     (a) the Redemption Date,

     (b) the Redemption Price,

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

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

     (e) the place or places where such Securities, together in the case of
Bearer Securities with all coupons appertaining thereto, if any, maturing after
the Redemption Date, are to be surrendered for payment of the Redemption Price,
which shall be the office or agency maintained by the Corporation in each Place
of Payment pursuant to Section 10.2, and

                                       56

<PAGE>

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

A notice of redemption published as contemplated by Section 1.6 need not
identify particular Registered Securities to be redeemed.

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

              Section 11.5 Deposit of Redemption Price. On or prior to any
Redemption Date, the Corporation shall deposit with the Trustee or with a Paying
Agent (or, if the Corporation is acting as its own Paying Agent, segregate and
hold in trust as provided in Section 10.3) an amount of money sufficient to pay
the Redemption Price of, and (except if the Redemption Date is an Interest
Payment Date) accrued interest, if any, on, all the Securities which are to be
redeemed on that date.

              Section 11.6 Securities Payable on Redemption Date. Notice of
redemption having been given as aforesaid, and the conditions, if any, set forth
in such notice having been satisfied, 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 Corporation defaults in the
payment of the Redemption Price and accrued interest, if any,) such Securities
shall cease to bear interest and the coupons for such interest appertaining to
any Bearer Securities so to be redeemed, except to the extent provided below,
shall be void. Upon surrender of any such Security for redemption in accordance
with said notice, together with all coupons, if any, appertaining thereto
maturing after the Redemption Date, such Security shall be paid by the
Corporation at the Redemption Price, together with accrued interest, if any, to
the Redemption Date; provided, that installments of interest on Bearer
Securities whose Stated Maturity is on or prior to the Redemption Date shall be
payable only upon presentation and surrender of coupons for such interest (at an
office or agency located outside the United States except as otherwise provided
in Section 10.2); and provided further, that installments of interest on
Registered Securities whose Stated Maturity is on or prior to the Redemption
Date shall be payable to the Holders of such Securities, or one or more
Predecessor Securities, registered as such at the close of business on the
relevant Record Dates according to their terms and the provisions of Section
3.7.

              If any Bearer Security surrendered for redemption is not
accompanied by all appurtenant coupons maturing after the Redemption Date, such
Security may be paid after deducting from the Redemption Price an amount equal
to the face amount of all such missing coupons, or the surrender of such missing
coupon or coupons may be waived by the Corporation and the Trustee if there is
furnished to them such security or indemnity as they may require to save each of
them and any Paying Agent harmless. If thereafter the Holder of such Security
surrenders 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, that interest
represented by coupons shall be payable only upon presentation and surrender of
those coupons at an office or agency located outside of the United States except
as otherwise provided in Section 10.2.

                                       57

<PAGE>

              If any Security called for redemption is not 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 11.7 Securities Redeemed in Part. Any Security which is to
be redeemed only in part shall be surrendered at a Place of Payment therefor
(with, if the Corporation or the Trustee so requires with respect to any
Registered Security, due endorsement by, or a written instrument of transfer in
form satisfactory to the Corporation and the Trustee duly executed by, the
Holder thereof or his attorney duly authorized in writing), and the Corporation
shall execute, and the Trustee shall authenticate and deliver to the Holder of
such Security without service charge, a new Security or Securities of the same
series, Stated Maturity and of any authorized denomination as requested by such
Holder, in aggregate principal amount equal to and in exchange for the
unredeemed portion of the principal of the Security so surrendered.

              Except as otherwise specified as contemplated by Section 3.1, if a
Global Security is so surrendered, the Corporation shall execute, and the
Trustee shall authenticate and deliver to the Depositary in global form, without
service charge, a new Global Security or Securities of the same series, Stated
Maturity and of any authorized denomination as requested by the Depositary, in
an aggregate principal amount equal to and in exchange for the unredeemed
portion of the principal of the Global Security so surrendered.

                                 ARTICLE TWELVE

                                  Sinking Funds

              Section 12.1 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 12.2. 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 12.2 Satisfaction of Sinking Fund Payments with
Securities. The Corporation (1) may deliver Outstanding Securities of a series
(other than any previously called for redemption), together in the case of any
Bearer Securities of such series with all unmatured coupons appertaining
thereto, and (2) may apply as a credit Securities of a series which have been
redeemed either at the election of the Corporation 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

                                       58

<PAGE>

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 12.3 Redemption of Securities for Sinking Fund. Not less
than 60 days prior to each sinking fund payment date for any series of
Securities, the Corporation shall 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 to Section 12.2 and stating the basis for such credit and that such
Securities have not previously been so credited and shall 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
11.3 and cause notice of the redemption thereof to be given in the name of and
at the expense of the Corporation in the manner provided in Section 11.4. Such
notice having been duly given, the redemption of such Securities shall be made
upon the terms and in the manner stated in Sections 11.6 and 11.7.

              Section 13.1 Purposes for Which Meetings May be Called. If

this Indenture to be made, given or taken by Holders of Securities of such
series.

              Section 13.2 Call Notice and Place of Meeting.

              (a) The Trustee may at any time call a meeting of Holders of
Securities of any series for any purpose specified in Section 13.1, to be held
at such time and at such place in the Borough of Manhattan, The City of New
York, or in London, as the Trustee shall determine. Notice of every meeting of

Outstanding Securities of any series shall have requested the Trustee to call a
meeting of the Holders of Securities of such series for any purpose specified in
Section 13.1, by written request setting forth in reasonable detail the action
proposed to be taken at the meeting, and the Trustee shall not have made the
first publication of the notice of such meeting within 21 days after receipt of
such request or shall not thereafter proceed to cause the meeting to be held as
provided herein, then the Corporation or the Holders of Securities of such
series in the amount above specified, as the case may be, may determine the

                                       59

<PAGE>

constitute a quorum for a meeting of Holders of Securities of such series. In
the absence of a quorum within 30 minutes of the time appointed for any such

present as aforesaid may be adopted only by the affirmative vote of the Holders
of a majority in principal amount of the Outstanding Securities of that series;
provided, that, except as limited by the proviso to Section 9.2, any resolution

waiver or other action which this Indenture expressly provides may be made,
given or taken by the Holders of a specified percentage, which is less than a
majority, in principal amount of the Outstanding Securities of a series may be
adopted at a meeting or an adjourned meeting duly reconvened and at which a

binding on all the Holders of Securities of such series and the related coupons,
whether or not present or represented at the meeting.

the holding of Securities shall be proved in the manner specified in Section
1.4, and the appointment of any proxy shall be proved in the manner specified in

              (b) The Trustee shall, by an instrument in writing, appoint a
temporary chairman of the meeting, unless the meeting shall have been called by
the Corporation or by Holders of Securities as provided in Section 13.2(b), in
which case the Corporation or the Holders of Securities of the series calling
the meeting, as the case may be, shall in like manner appoint a temporary
chairman. A permanent chairman and a permanent secretary of the meeting shall be
elected by vote of the Persons entitled to vote a majority in principal amount
of the Outstanding Securities of such series represented at the meeting.

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

              (d) Any meeting of Holders of Securities of any series duly called
pursuant to Section 13.2 at which a quorum is present may be adjourned from time
to time by Persons entitled to vote a majority in principal amount of the
Outstanding Securities of such series represented at the meeting; and the
meeting may be held as so adjourned without further notice.

any series shall be by written ballots on which shall be subscribed the
signatures of the Holders of Securities of such series or of their
representatives by proxy and the principal amounts and serial numbers of the

chairman of the meeting shall appoint two inspectors of votes who shall count
all votes cast at the meeting for or against any resolution and who shall make
and file with the secretary of the meeting their verified written reports in
triplicate of all votes cast at the meeting. A record, at least in triplicate,
of the proceedings of each meeting of Holders of Securities of any series shall
be prepared by the secretary of the meeting, and there shall be attached to said
record the original reports of the inspectors of votes on any vote by ballot
taken thereat and affidavits by one or more persons having knowledge of the
facts setting forth a copy of the notice of the meeting and showing that said
notice was given as provided in Section 13.2 and, if applicable, Section 13.4.
Each copy shall be signed and verified by the affidavits of the permanent
chairman and secretary of the meeting, and one such copy shall be delivered to
the Corporation and another to the

                                       61

<PAGE>

Trustee to be preserved by the Trustee, the latter to have attached thereto the
ballots voted at the meeting. Any record so signed and verified shall be
conclusive evidence of the matters therein stated.

              Section 13.7 Action Without Meeting. In lieu of a vote of Holders
at a meeting as hereinbefore contemplated in this Article, any request, demand,
authorization, direction, notice, consent, waiver or other action may be made,
given or taken by Holders by written instruments as provided in Section 1.4.

                                ARTICLE FOURTEEN

of law, or by the enforcement of any assessment or penalty or otherwise; it
being expressly agreed and understood that this Indenture and all the Securities

indebtedness hereby authorized or under or by reason of any of the obligations,
covenants or agreements contained in this Indenture or in any of the Securities
or to be implied herefrom or therefrom, and that any such personal liability is
hereby expressly waived and released as a condition of, and as part of the
consideration for, the execution of this Indenture and the issuance of the
Securities.
