                  opinions contained in such certificate or opinion are based;

         (3)      a statement that, in the opinion of each such individual, he
                  has made such examination or investigation as is necessary to
                  enable him to express an informed opinion as to whether or not
                  such covenant or condition has been complied with; and

         (4)      a statement as to whether, in the opinion of each such
                  individual, such condition or covenant has been complied with.

SECTION 103.  FORM OF DOCUMENTS DELIVERED TO TRUSTEE.

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

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

                                       9
<PAGE>
information with respect to such factual matters is in the possession of the
Corporation, unless such counsel knows, or in the exercise of reasonable care
should know, that the certificate or opinion or representations with respect to
such matters are erroneous.

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

SECTION 104.  ACTS OF HOLDERS; RECORD DATES.

         Any request, demand, authorization, direction, notice, consent, waiver
or other action provided or permitted by this Indenture to be given, made or
taken by Holders 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; and, except as herein otherwise expressly provided,
such action shall become effective when such instrument or instruments are
delivered to the Trustee and, where it is herein expressly required, to the
Corporation. Such instrument or instruments (and the action embodied therein and
evidenced thereby) are herein sometimes referred to as the "Act" of the Holders
signing such instrument or instruments. Proof of execution of any such
instrument or of a writing appointing any such agent shall be sufficient for any
purpose of this Indenture and (subject to Section 601) conclusive in favor of
the Trustee and the Corporation, if made in the manner provided in this Section.

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

         The Security Register shall prove the ownership of Securities.

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

         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 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. If not set by the Corporation prior to the first solicitation of a
Holder of Securities 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 (or, if later, the date of the most recent
list of Holders required to be provided) prior to such first solicitation or
vote, as the case may be. With regard to any

                                       10
<PAGE>
record date, only the Holders of Securities on such date (or their duly
designated proxies) shall be entitled to give or take, or vote on, the relevant
action.

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

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

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

         (2)      the Corporation by the Trustee or by any Holder shall be
                  sufficient for every purpose hereunder (unless otherwise
                  herein expressly provided) if in writing and mailed,
                  first-class postage prepaid, to the Corporation addressed to:
                  the address last furnished in writing to the Trustee by the
                  Corporation, or, if no such address has been furnished,
                  Treasurer, United States Steel Corporation, 600 Grant Street,
                  Pittsburgh, Pennsylvania 15219-2800.

SECTION 106.  NOTICE TO HOLDERS; WAIVER.

         Where this Indenture provides for notice to Holders of any event, such
notice shall be sufficiently given (unless otherwise herein expressly provided)
if in writing and mailed, first-class postage prepaid, to each Holder affected
by such event, at the address as it appears in the Security Register, not later
than the latest date (if any), and not earlier than the earliest date (if any),
prescribed for the giving of such notice. In any case where notice to Holders is
given by mail, neither the failure to mail such notice, nor any defect in any
notice so mailed, to any particular Holder shall affect the sufficiency of such
notice with respect to other Holders. Where this Indenture provides for notice
in any manner, the Person entitled to receive such notice, either before or
after the event, may waive such notice in writing and such waiver shall be the
equivalent of such notice. Waivers of notice by Holders shall be filed with the
Trustee, but such filing shall not be a condition precedent to the validity of
any action taken in reliance upon such waiver.

         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.

SECTION 107.  CONFLICT WITH TRUST INDENTURE ACT.

     If any provision hereof limits, qualifies or conflicts with a provision of
the Trust Indenture Act that is required under such Act to be a part of and
govern this Indenture, the latter provision shall control. If any provision of
this Indenture modifies or excludes any provision of the Trust Indenture Act
that may be so modified or excluded, the latter provision shall be deemed to
apply to this Indenture as so modified or to be excluded, as the case may be.

                                       11

SECTION 108.  EFFECT OF HEADINGS AND TABLE OF CONTENTS.

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

SECTION 109.  SUCCESSORS AND ASSIGNS.

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

SECTION 110.  SEVERABILITY CLAUSE.

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

SECTION 111.  BENEFITS OF INDENTURE.

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

SECTION 112.  GOVERNING LAW.

         This Indenture and the Securities shall be governed by and construed in
accordance with the law of the State of New York.

SECTION 113.  LEGAL HOLIDAYS.

         In any case where any Interest Payment Date, Redemption Date or Stated
Maturity of any Security shall not be a Business Day at any Place of Payment,
then (notwithstanding any other provision of this Indenture or of the Securities
(other than a provision of any Security that specifically states that such
provision shall apply in lieu of this Section)) payment of interest or principal
(and premium, if any) need not be made at such Place of Payment on such date,
but may be made on the next succeeding Business Day at such Place of Payment
with the same force and effect as if made on the Interest Payment Date or
Redemption Date, or at the Stated Maturity.

                                   ARTICLE TWO
                                 SECURITY FORMS

SECTION 201.  FORMS GENERALLY.

         The Securities of each series shall be in substantially the form set
forth in this Article, or in such other form as shall be established by an
Establishment Action or in one or more indentures supplemental hereto, in each
case with such appropriate insertions, omissions, substitutions and other
variations as are required or permitted by this Indenture, and may have such

endorsements placed thereon as may be required to comply with the rules of any

pursuant to a Board Resolution, a copy of an appropriate record of such action
shall be certified by the Secretary or an Assistant Secretary of the Corporation

(5) to add to, change or eliminate any of the provisions of the Indenture in
respect of one or more series of Securities thereunder, under certain conditions
specified therein; (6) to secure the Securities; (7) to establish the form or
terms of Securities of any series as permitted by Sections 201 and 301 of the
Indenture; (8) to evidence the appointment of a successor Trustee; (9) to make
provision with respect to any conversion or exchange rights as specified as
contemplated pursuant to Section 301 of the Indenture; and (10) to cure any
ambiguity, to correct or supplement any provision of the Indenture which may be
defective or inconsistent with any other provision of the Indenture, or to make
any other provisions with respect to matters or questions arising under the
Indenture that do not materially adversely affect the interests of the Holders
in any material respect.

         The Indenture also permits, with certain exceptions set forth therein,
the amendment thereof and the modification of the rights and obligations of the
Corporation and the rights of the Holders of the Securities of each series to be
affected under the Indenture at any time by the Corporation and the Trustee with
the consent of the Holders of a majority in principal amount of the Securities
at the time Outstanding of each series to be affected. The Indenture also
contains provisions permitting the Holders of specified percentages in principal
amount of the Securities of each series at the time Outstanding, on behalf of
the Holders of all Securities of such series, to waive compliance by the
Corporation with certain provisions of the Indenture and certain past defaults
under the Indenture and their consequences. Any such consent or waiver by the
Holder of this Security shall be conclusive and binding upon such Holder and
upon all future Holders of this Security and of any Security issued upon the
registration of transfer hereof or in exchange therefor or in lieu hereof,
whether or not notation of such consent or waiver is made upon this Security.

         As provided in and subject to the provisions of the Indenture, the
Holder of this Security shall not have the right to institute any proceeding
with respect to the Indenture or for the appointment of a receiver or trustee or
for any other remedy thereunder, unless such Holder shall have previously given
the Trustee written notice of a continuing Event of Default with respect to the
Securities of this series, the Holders of not less than 25% in principal amount
of the Securities of this series at the time Outstanding shall have made written
request to the Trustee to institute proceedings in respect of such Event of
Default as Trustee and offered the Trustee reasonable indemnity, and the Trustee
shall not have received from the Holders of a majority in principal amount of
Securities of this series at the time Outstanding a direction inconsistent with
such request, and shall have failed to institute any such proceeding, for 60
days after receipt of such notice, request and offer of indemnity. The foregoing
shall not apply to any suit instituted by the Holder of this Security for the
enforcement of any payment of principal hereof or any premium or interest hereon
on or after the respective due dates expressed herein.

         No reference herein to the Indenture and no provision of this Security
or of the Indenture shall alter or impair the obligation of the Corporation,
which is absolute and unconditional, to pay the principal of and any premium and
interest on this Security at the times, place and rate, and in the coin or
currency, herein prescribed.

         As provided in the Indenture and subject to certain limitations therein
set forth,

surrender of this Security for registration of transfer at the office or agency
of the Corporation in any place where the principal of and any premium and
interest on this Security are payable, duly endorsed by, or accompanied by a
written instrument of transfer in form satisfactory to the Corporation and the
Security Registrar duly executed by, the Holder hereof or his attorney duly
authorized in writing, and thereupon one or more new Securities of this series
and of like tenor, of authorized denominations and for the same aggregate
principal amount, will be issued to the designated transferee or transferees.

         The Securities of this series are issuable only in registered form
without coupons in denominations of $________ and any integral multiple thereof.
As provided in the Indenture and subject to certain limitations therein set
forth, Securities of this series are exchangeable for a like aggregate principal
amount of Securities of this series and of like tenor of a different authorized
denomination, as requested by the Holder surrendering the same.

         No service charge shall be made for any such registration of transfer
or exchange, but the Corporation or the Trustee may require payment of a sum
sufficient to cover any tax or other governmental charge payable in connection
therewith.

         Prior to due presentment of this Security for registration of transfer,
the Corporation, the Trustee and any agent of the Corporation or the Trustee may

                  Resolution, the manner in which any election by the

                  purchase any Securities of the series pursuant to any sinking

         (13)     if other than the entire principal amount thereof, the portion
                  of the principal amount of any Securities of the series which
                  shall be payable upon declaration of acceleration of the
                  Maturity thereof pursuant to Section 502;

         (14)     if the principal amount payable at the Stated Maturity of any
                  Securities of the series will not be determinable as of any
                  one or more dates prior to the Stated Maturity, the amount

<PAGE>
                  thereunder or hereunder, including the principal amount
                  thereof which shall be due and payable upon any Maturity other
                  than the Stated Maturity or which shall be deemed to be

                  in any such case, the manner in which such amount deemed to be
                  the principal amount shall be determined);

                  by another method, such other method) and, if other than by an
                  action pursuant to a Board Resolution, the manner in which any

                  such Global Securities, the form of any legend or legends
                  which shall be borne by any such Global Security in addition
                  to or in lieu of that set forth in Section 204 and any
                  circumstances in addition to or in lieu of those set forth in
                  Clause (2) of the last paragraph of Section 305 in which any
                  such Global Security may be exchanged in whole or in part for
                  Securities registered, and any transfer of such Global
                  Security in whole or in part may be registered, in the name or
                  names of Persons other than the Depositary for such Global
                  Security or a nominee thereof;

         (17)     any addition to or change in the Events of Default which
                  applies to any Securities of the series and any change in the
                  right of the Trustee or the requisite Holders of such
                  Securities to declare the principal amount thereof due and
                  payable pursuant to Section 502;

         (18)     any addition to or change in the covenants set forth in
                  Article Ten which applies to Securities of the series;

         (19)     if the Securities are subordinate other than in accordance
                  with Article Fourteen, such other subordination provisions;
                  and

         (20)     if the Securities of the series are convertible into, or
                  exchangeable for, other securities, the terms and conditions
                  pursuant to which the Securities of the series will be
                  convertible or exchangeable; and

         (21)     any other terms of the series (which terms shall not be
                  inconsistent with the provisions of this Indenture, except as
                  permitted by Section 901(5)).

         All Securities of any one series shall be substantially identical
except as to denomination and except as may otherwise be provided in the
Establishment Action referred to above or in any indenture supplemental hereto.
The Corporation shall provide to the Trustee a copy of any such Establishment
Action. The Securities shall be subordinated in right of payment to Senior Debt
as provided in Article Fourteen and/or as specified as contemplated pursuant to
this section.

SECTION 302.  DENOMINATIONS.

         The Securities of each series shall be issuable only in registered form
without coupons and only in such denominations as shall be specified as
contemplated by Section 301. In the absence of any such specified denomination
with respect to the Securities of any series, the Securities of such series
shall be issuable in denominations

                                       21
<PAGE>
of $1,000 and any integral multiple thereof.

SECTION 303.  EXECUTION, AUTHENTICATION, DELIVERY AND DATING.

         The Securities shall be executed on behalf of the Corporation by its
Chairman of the Board, any Vice Chairman of the Board, its President or one of
its Vice Presidents, under its corporate seal reproduced thereon attested by its
Treasurer or an Assistant Treasurer or its Secretary or one of its Assistant
Secretaries. The signature of any of these officers on the Securities may be
manual or facsimile. The seal of the Corporation may be in the form of a
facsimile thereof and may be impressed, affixed, imprinted or otherwise
reproduced on the Security.

         Securities bearing the manual or facsimile signatures of individuals
who were at any time 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 by
the Corporation to the Trustee for authentication, together with a Corporation
Order for the authentication and delivery of such Securities, and the Trustee in
accordance with the Corporation Order shall authenticate and deliver such
Securities. If the form or terms of the Securities of the series have been
established by one or more Establishment Actions as permitted by Sections 201
and 301, in authenticating such Securities, and accepting the additional
responsibilities under this Indenture in relation to such Securities, the
Trustee shall be entitled to receive, and (subject to Section 601) shall be
fully protected in relying upon, an Opinion of Counsel stating,

         (1)      if the form of such Securities has been established by an
                  Establishment Action as permitted by Section 201, that such
                  form has been established in conformity with the provisions of
                  this Indenture;

         (2)      if the terms of such Securities have been established by an
                  Establishment Action as permitted by Section 301, that such
                  terms have been established in conformity with the provisions
                  of this Indenture; and

         (3)      that such Securities, when authenticated and delivered by the
                  Trustee and issued by the Corporation in the manner and
                  subject to any conditions specified in such Opinion of
                  Counsel, will constitute valid and legally binding obligations
                  of the Corporation enforceable in accordance with their terms,
                  subject to bankruptcy, insolvency, fraudulent transfer,
                  reorganization, moratorium and similar laws of general
                  applicability relating to or affecting creditors' rights and
                  to general equity principles.

         If such form or terms have been so established, the Trustee shall not
be required to authenticate such Securities if the issue of such Securities
pursuant to this Indenture will affect the Trustee's own rights, duties or
immunities under the Securities and this Indenture or otherwise in a manner
which is not reasonably acceptable to the Trustee.

         Notwithstanding the provisions of Section 301 and of the preceding
paragraph, if

                                       22
<PAGE>
all Securities of a series are not to be originally issued at one time, it shall
not be necessary to deliver the Establishment Action otherwise required pursuant
to Section 301 or the Corporation Order and Opinion of Counsel otherwise
required pursuant to such preceding paragraph at or prior to the authentication
of each Security of such series if such documents are delivered at or prior to
the authentication upon original issuance of the first Security of such series
to be issued.

         Each Security shall be dated the date of its authentication.

         No Security 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. Notwithstanding the
foregoing, if any Security shall have been authenticated and delivered hereunder
but never issued and sold by the Corporation, and the Corporation shall deliver
such Security to the Trustee for cancellation as provided in Section 309, for
all purposes of this Indenture such Security shall be deemed never to have been
authenticated and delivered hereunder and shall never be entitled to the
benefits of this Indenture.

SECTION 304.  TEMPORARY SECURITIES.

         Pending the preparation of definitive Securities of any series, the
Corporation may execute, and upon Corporation Order 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 and with such appropriate insertions, omissions, substitutions and
other variations as the officers executing such Securities may determine, as
evidenced by their execution of such Securities.

         If temporary Securities of any series are issued, the Corporation will
cause definitive Securities of that series to be prepared without unreasonable
delay. After the preparation of definitive Securities of such series, the
temporary Securities of such series shall be exchangeable for definitive
Securities of such series upon surrender of the temporary Securities of such
series at the office or agency of the 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, the Corporation shall execute and
the Trustee shall authenticate and deliver in exchange therefor one or more
definitive Securities of the same series, of any authorized denominations and of
like tenor and aggregate principal amount. Until so exchanged, the temporary
Securities of any series shall in all respects be entitled to the same benefits
under this Indenture as definitive Securities of such series and tenor.

SECTION 305.  REGISTRATION, REGISTRATION OF TRANSFER AND EXCHANGE.

         The Corporation shall cause to be kept in an office or agency of the
Corporation in a Place of Payment a register (the register maintained in any
such office or agency of the Corporation in a Place of Payment being herein
sometimes collectively referred to as the "Security Register") in which, subject
to such reasonable regulations as it may prescribe, the Corporation shall
provide for the registration of Securities and of transfers

                                       23
<PAGE>
of Securities. The Trustee, or any other party serving in such capacity with the
Trustee's consent, is hereby appointed "Security Registrar" for the purpose of
registering Securities and transfers of Securities as herein provided.

         Upon surrender for registration of transfer of any Security of a series
at the office or agency of the Corporation in a Place of Payment for that
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 Securities of the same series, of any authorized denominations and of like
tenor and aggregate principal amount.

         At the option of the Holder, Securities of any series may be exchanged
for other Securities of the same series, of any authorized denominations and of
like tenor and aggregate principal amount, upon surrender of the Securities to
be exchanged at such office or agency. Whenever any Securities are so
surrendered for exchange, the Corporation shall execute, and the Trustee shall
authenticate and deliver, the Securities that 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 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 304, 906 or 1107 not involving any transfer.

         If the Securities of any series (or of any series and specified tenor)
are to be redeemed in part, the Corporation shall not be required (A) to issue,
register the transfer of or exchange any Securities of that series (or of that
series and specified tenor, as the case may be) during a period beginning at the
opening of business 15 days before the day of the mailing of a notice of
redemption of any such Securities selected for redemption under Section 1103 and
ending at the close of business on the day of such mailing, or (B) to register
the transfer of or exchange any Security so selected for redemption in whole or
in part, except the unredeemed portion of any Security being redeemed in part.

         The provisions of the following clauses shall apply only to Global
Securities:

         (1)      Each Global Security authenticated under this Indenture shall
                  be registered in the name of the Depositary designated for
                  such Global Security or a nominee thereof and delivered to
                  such Depositary or a nominee thereof or custodian therefor,
                  and each such Global Security shall constitute a single
                  Security for all purposes of this Indenture.

                                       24
<PAGE>
         (2)      Notwithstanding any other provision in this Indenture, no
                  Global Security may be exchanged in whole or in part for
                  Securities registered, and no transfer of a Global Security in
                  whole or in part may be registered, in the name of any Person
                  other than the Depositary for such Global Security or a
                  nominee thereof unless

                  (A)      such Depositary

                           (i)      has notified the Corporation that it is
                                    unwilling or unable to continue as
                                    Depositary for such Global Security or

                           (ii)     has ceased to be a clearing agency
                                    registered under the Exchange Act,

                  (B)      there shall have occurred and be continuing an Event
                           of Default with respect to such Global Security or

                  (C)      there shall exist such circumstances, if any, in
                           addition to or in lieu of the foregoing as have been
                           specified for this purpose as contemplated by Section
                           301.

         (3)      Subject to Clause (2) above, any exchange of a Global Security
                  for other Securities may be made in whole or in part, and all
                  Securities issued in exchange for a Global Security or any
                  portion thereof shall be registered in such names as the
                  Depositary for such Global Security shall direct.

         (4)      Every Security authenticated and delivered upon registration
                  of transfer of, or in exchange for or in lieu of, a Global
                  Security or any portion thereof, whether pursuant to this
                  Section, Section 304, 306, 906 or 1107 or otherwise, shall be
                  authenticated and delivered in the form of, and shall be, a
                  Global Security, unless such Security is registered in the
                  name of a Person other than the Depositary for such Global
                  Security or a nominee thereof.

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

         If any mutilated Security 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 and of like tenor and
principal amount and bearing a number not contemporaneously outstanding.

         If there shall be delivered to the Corporation and the Trustee

    (i)  evidence to their satisfaction of the destruction, loss or theft of any
         Security and

    (ii) such security or indemnity as may be required by them to save each of
         them and any agent of either of them harmless,

then, in the absence of notice to the Corporation or the Trustee that such
Security has been acquired by a bona fide purchaser, the Corporation shall
execute and the Trustee

                                       25
<PAGE>
shall authenticate and deliver, in lieu of any such destroyed, lost or stolen
Security, a new Security of the same series and of like tenor and principal
amount and bearing a number not contemporaneously outstanding.

         In case any such mutilated, destroyed, lost or stolen Security 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.

         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 issued pursuant to this Section in
lieu of any destroyed, lost or stolen Security shall constitute an original
additional contractual obligation of the Corporation, whether or not the
destroyed, lost or stolen Security shall be at any time enforceable by anyone,
and shall be entitled to all the benefits of this Indenture equally and
proportionately with any and all other Securities of that series 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.

SECTION 307.  PAYMENT OF INTEREST; INTEREST RIGHTS PRESERVED.

         Except as otherwise provided as contemplated by Section 301 with
respect to any series of Securities, interest on any 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.

         Any interest on any 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 (1) or (2) below:

         (1)      The Corporation may elect to make payment of any Defaulted
                  Interest to the Persons in whose names the 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 Corporation shall notify
                  the Trustee in writing of the amount of Defaulted Interest
                  proposed to be paid on each 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

                                       26
<PAGE>
                  benefit of the Persons entitled to such Defaulted Interest as
                  in this Clause provided. Thereupon the Trustee shall fix a
                  Special Record Date for the payment of such Defaulted Interest
                  that 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 given to each Holder of Securities
                  of such series in the manner set forth in Section 106, not
                  less than 10 days prior to such Special Record Date. Notice of
                  the proposed payment of such Defaulted Interest and the
                  Special Record Date therefor having been so mailed, such
                  Defaulted Interest shall be paid to the Persons in whose names
                  the Securities of such series (or their respective Predecessor
                  Securities) are registered at the close of business on such
                  Special Record Date and shall no longer be payable pursuant to
                  the following Clause (2).

         (2)      The 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.

         If the Securities of the series are convertible or exchangeable and
unless otherwise specified as contemplated by Section 301, in the case of any
Security of such series which is converted or exchanged after any Regular Record
Date and on or prior to the next succeeding Interest Payment Date (other than
any Security whose Maturity is prior to such Interest Payment Date), interest
whose Stated Maturity is on such Interest Payment Date shall be payable on such
Interest Payment Date notwithstanding such conversion or exchange, and such
interest (whether or not punctually paid or duly provided for) 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 such Regular Record Date. Except as
otherwise expressly provided in the immediately preceding sentence, in the case
of any Security which is converted or exchanged, interest whose Stated Maturity
is after the date of conversion or exchange of such Security shall not be
payable.

         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 308.  PERSONS DEEMED OWNERS.

         Prior to due presentment of a Security for registration of transfer,
the Corporation, the Trustee and any agent of the Corporation or the Trustee may
treat the Person in whose name such Security is registered as the owner of such
Security for the purpose of receiving payment of principal of and any premium
and (subject to Section 307) any interest on such Security and for all other
purposes whatsoever, whether or not such Security be overdue, and neither the
Corporation, the Trustee nor any agent of the Corporation or the Trustee shall
be affected by notice to the contrary.

SECTION 309.  CANCELLATION.

         All Securities 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 cancelled by it. 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 may deliver to the Trustee (or to any other Person for delivery
to the Trustee) for cancellation any Securities previously authenticated
hereunder which the Corporation has not issued and sold, and all

                                       27
<PAGE>
Securities so delivered shall be promptly cancelled by the Trustee. No
Securities shall be authenticated in lieu of or in exchange for any Securities
cancelled as provided in this Section, except as expressly permitted by this
Indenture. Until directed otherwise by a Corporation Order, all cancelled
Securities held by the Trustee shall be conspicuously marked as such and, if
destroyed, the Trustee shall deliver to the Corporation a certificate with
respect to such destruction.

SECTION 310.  COMPUTATION OF INTEREST.

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

                           SATISFACTION AND DISCHARGE

SECTION 401.  SATISFACTION AND DISCHARGE OF INDENTURE.

         This Indenture shall upon Corporation Request cease to be of further
effect with respect to any (or all) series of Securities (except as to any
surviving rights of registration of transfer or exchange of Securities herein
expressly provided for), and the Trustee, at the expense of the Corporation,
shall execute proper instruments acknowledging satisfaction and discharge of
this Indenture with respect to such Securities, when

         (1)      either

                  (A)      all such Securities theretofore authenticated and
                           delivered (other than

                           (i)      Securities which have been destroyed, lost
                                    or stolen and which have been replaced or
                                    paid as provided in Section 306 and

                           (ii)     Securities for whose payment money has
                                    theretofore been deposited in trust or

                                    Corporation and thereafter repaid to the
                                    Corporation or discharged from such trust,
                                    as provided in Section 1003)

                           have been delivered to the Trustee for cancellation;
                           or

                  (B)      all such Securities not theretofore delivered to the

                                    year under arrangements satisfactory to the
                                    Trustee for the giving of

<PAGE>
                                    notice of redemption by the Trustee in the
                                    name, and at the expense, of the
                                    Corporation,

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

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

         (3)      the Corporation has delivered to the Trustee an Officers'

         Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Corporation to the Trustee under Section 607, the obligations
of the Trustee to any Authenticating Agent under Section 614 and, if money shall
have been deposited with the Trustee pursuant to subclause (B) of Clause (1) of
this Section, the obligations of the Trustee under Section 402, Article Six and
the last paragraph of Section 1003 shall survive.

SECTION 402.  APPLICATION OF TRUST MONEY.

         Subject to the provisions of the last paragraph of Section 1003, all
money deposited with the Trustee pursuant to Section 401 shall be held in trust
and applied by it, in accordance with the provisions of the Securities 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 any premium and
interest for whose payment such money has been deposited with the Trustee.

SECTION 502.  ACCELERATION OF MATURITY; RESCISSION AND ANNULMENT.

         If an Event of Default (other than an Event of Default specified in
Section 501(5) or 501(6)) 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 of all the Securities of that
series (or, if any Securities of that series are Original Issue Discount
Securities, such portion of the principal amount of such Securities as may be
specified by the terms thereof) 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. If an Event of Default specified in Section 501(5)
or 501(6) with respect to Securities of any series at the time Outstanding
occurs, the principal amount of all the Securities of that series (or, if any
Securities of that series are Original Issue Discount Securities, such portion
of the principal amount of such Securities as may be specified by the terms
thereof) shall automatically, and without any declaration or other action on the
part of the Trustee or any Holder, 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

                                       31
<PAGE>

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

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

            (A)   all overdue interest on all Securities of that series,

            (B)   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 any interest thereon at the
                  rate or rates prescribed therefor in such Securities,

            (C)   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

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

      and

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

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

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

The Corporation covenants that if

      (1)   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

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

the Corporation will, upon demand of the Trustee, pay to it, for the benefit of
the Holders of such Securities, the whole amount then due and payable on such
Securities for principal and any premium and interest and, to the extent that
payment of such interest shall be legally enforceable, interest on any overdue
principal and premium and on any overdue interest, at the rate or rates (or
yield to maturity in the case of Original Issue Discount Securities) 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

                                       32
<PAGE>
Trustee, its agents and counsel, except as a result of the Trustee's negligence
or bad faith.

      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 by such
appropriate judicial proceedings as the Trustee shall deem most effectual to
protect and enforce any such rights, whether for the specific enforcement of any
covenant or agreement in this Indenture or in aid of the exercise of any power
granted herein, or to enforce any other proper remedy.

SECTION 504. TRUSTEE MAY FILE PROOFS OF CLAIM.

      In case of any judicial proceeding relative to the Corporation (or any
other obligor upon the Securities), its property or its creditors, the Trustee
shall be entitled and empowered, by intervention in such proceeding or
otherwise, to take any and all actions authorized under the Trust Indenture Act
in order to have claims of the Holders and the Trustee allowed in any such
proceeding. In particular, the Trustee shall be authorized to collect and
receive any moneys or other property payable or deliverable on any such claims
and to distribute the same; and any custodian, receiver, assignee, trustee,
liquidator, sequestrator or other similar official in any such judicial
proceeding is hereby authorized by each Holder to make such payments to the
Trustee and, in the event that the Trustee shall consent to the making of such
payments directly to the Holders, to pay to the Trustee any amount due it for
the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel, and any other amounts due the Trustee under
Section 607 except as a result of its negligence or bad faith.

      No provision of this Indenture shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Holder any plan of
reorganization, arrangement, adjustment or composition affecting the Securities
or the rights of any Holder thereof or to authorize the Trustee to vote in
respect of the claim of any Holder in any such proceeding; provided, however,
that the Trustee may, on behalf of the Holders, vote for the election of a
trustee in bankruptcy or similar official and be a member of a creditors' or
other similar committee.

SECTION 505. TRUSTEE MAY ENFORCE CLAIMS WITHOUT POSSESSION OF SECURITIES.

      All rights of action and claims under this Indenture or the Securities may
be prosecuted and enforced by the Trustee without the possession of any of the
Securities 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 (except no such provision shall
be made respecting compensation, expenses, disbursements and advances made as a
result of Trustee's negligence), be for the ratable benefit of the Holders of
the Securities in respect of which such judgment has been recovered.

SECTION 506. APPLICATION OF MONEY COLLECTED.

      Any money collected by the Trustee pursuant to this Article shall be
applied in the following order, at the date or dates fixed by the Trustee and,
in case of the distribution of such money on account of principal or any premium
or interest, upon presentation of the Securities and the notation thereon of the
payment if only partially paid and upon surrender thereof if fully paid:

      FIRST: To the payment of costs and expenses of collection, reasonable
compensation to the Trustee, its agents, attorneys and counsel, and all other
expenses and liabilities incurred, and all advances made, by the Trustee except
as a result of its negligence or bad faith.

      SECOND: Subject to Article Fourteen, in case the principal of the
outstanding Securities of any series in respect of which such moneys have been
collected shall not have become due, to the payment of interest on the
Securities of such series, in the order of maturity of the installments of such
interest, with interest (to the extent that such interest has been collected by
the Trustee) upon the overdue installments of interest at the same rate or the
yield to maturity (in the case of Original Issue Discount Securities) specified
on the Securities of such series, such payments to be made ratably to the
persons entitled thereto, without discrimination or preference.

      THIRD: Subject to Article Fourteen, in case the principal of the
outstanding Securities of any series in respect of which such moneys have been
collected shall have become due, by declaration, or otherwise, to the payment of
the whole amount then owing and unpaid upon the Securities of such series for
principal, premium (if any) and interest, with interest upon the overdue
principal, premium (if any) and (to the extent that such interest has been
collected by the Trustee) upon overdue installments of interest at the same rate
or the yield to maturity (in the case of Original Issue Discount Securities)
specified on the Securities of such series; and in case such moneys shall be
insufficient to pay in full the whole amount so due and unpaid upon the
Securities of such series, then to the payment of such principal, premium (if
any) and interest, without preference or priority of principal and premium (if
any), or of any installment of interest over any other installment of interest,
or of any Security of such series over any other Security of such series,
ratably to the aggregate of such principal and accrued and unpaid interest.

SECTION 507. LIMITATION ON SUITS.

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

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

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

      (3)   such Holder or Holders have offered to the Trustee reasonable
            indemnity

                                       34
<PAGE>
            against the costs, expenses and liabilities to be incurred in
            compliance with such request;

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

      (5)   no direction inconsistent with such written request has been given
            to the Trustee during such 60-day period by the Holders of a
            majority in principal amount of the Outstanding 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 508. UNCONDITIONAL RIGHT OF HOLDERS TO RECEIVE PRINCIPAL, PREMIUM AND
INTEREST.

      Notwithstanding any other provision in this Indenture, the Holder of any
Security shall have the right, which is absolute and unconditional, to receive
payment of the principal of and any premium and (subject to Section 307)
interest on such Security on the respective Stated Maturities expressed in such
Security (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 509. RESTORATION OF RIGHTS AND REMEDIES.

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

SECTION 510. RIGHTS AND REMEDIES CUMULATIVE.

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

                                       35
<PAGE>
SECTION 511. DELAY OR OMISSION NOT WAIVER.

      No delay or omission of the Trustee or of any Holder of any Securities to
exercise any right or remedy accruing upon any Event of Default shall impair any
such right or remedy or constitute a waiver of any such Event of Default or an
acquiescence therein. Every right and remedy given by this Article or by law to
the Trustee or to the Holders may be exercised from time to time, and as often
as may be deemed expedient, by the Trustee or by the Holders, as the case may
be.

SECTION 512. CONTROL BY HOLDERS.

      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

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

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

SECTION 513. WAIVER OF PAST DEFAULTS.

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

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

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

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

SECTION 514. UNDERTAKING FOR COSTS.

      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, a court may require any party litigant in such suit to
file an undertaking to pay the costs of such suit, and may assess costs against
any such party litigant, in the manner and to the extent provided in the Trust
Indenture Act; provided that neither this Section nor the Trust Indenture Act
shall be deemed to authorize any court to require such an undertaking or to make
such an assessment in any suit instituted by the Corporation.

                                       36
<PAGE>
SECTION 515. WAIVER OF USURY, STAY OR EXTENSION LAWS.

      The Corporation covenants (to the extent that it may lawfully do so) that
it will not at any time insist upon, or plead, or in any manner whatsoever claim
or take the benefit or advantage of, any usury, 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 will not hinder, delay or impede the execution of any
power herein granted to the Trustee, but will suffer and permit the execution of
every such power as though no such law had been enacted.

                                   ARTICLE SIX
                                   THE TRUSTEE

SECTION 601. CERTAIN DUTIES AND RESPONSIBILITIES.

      The duties and responsibilities of the Trustee shall be as provided by the
Trust Indenture Act. Notwithstanding the foregoing, no provision of this
Indenture shall require the Trustee to expend or risk its own funds or otherwise
incur any financial liability in the performance of any of its duties hereunder,
or in the exercise of any of its rights or powers, if it shall have reasonable
grounds for believing that repayment of such funds or adequate indemnity against
such risk or liability is not reasonably assured to it. Whether or not therein
expressly so provided, every provision of this Indenture relating to the conduct
or affecting the liability of or affording protection to the Trustee shall be
subject to the provisions of this Section.

SECTION 602. NOTICE OF DEFAULTS.

      If a default occurs hereunder with respect to Securities of any series,
the Trustee shall give the Holders of Securities of such series notice of such
default as and to the extent provided by the Trust Indenture Act; provided,
however, that in the case of any default of the character specified in Section
501(4) with respect to Securities of such series, no such notice to Holders
shall be given until at least 60 days after the occurrence thereof. For the
purpose of this Section, the term "default" means any event or events, as the
case may be, specified in Section 501, not including periods of grace, if any,
provided for therein.

SECTION 603. CERTAIN RIGHTS OF TRUSTEE.

      Subject to the provisions of Section 601:

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

      (2)   any request or direction of the Corporation mentioned herein shall
            be sufficiently evidenced by a Corporation Request or Corporation
            Order, and any resolution of the Board of Directors or Establishment
            Action may

                                       37
<PAGE>
            be sufficiently evidenced by a Board Resolution or Establishment
            Action, as the case may be;

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

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

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

      (6)   the Trustee shall not be bound to make any investigation into the
            facts or matters stated in any resolution, action, certificate,
            statement, instrument, opinion, report, notice, request, direction,
            consent, order, bond, debenture, note, other evidence of
            indebtedness or other paper or document, but the Trustee, in its
            discretion, may make such further inquiry or investigation into such
            facts or matters as it may see fit, and, if the Trustee shall
            determine to make such further inquiry or investigation, it shall be
            entitled to examine the books, records and premises of the
            Corporation, personally or by agent or attorney;

      (7)   the Trustee may execute any of the trusts or powers hereunder or
            perform any duties hereunder either directly or by or through agents
            or attorneys and the Trustee shall not be responsible for any
            misconduct or negligence on the part of any agent or attorney
            appointed with due care by it hereunder; and

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

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

      The recitals contained herein and in the Securities, except the Trustee's
certificates of authentication, shall be taken as the statements of the
Corporation, and neither the Trustee nor any Authenticating Agent assumes any
responsibility for their correctness. The Trustee makes no representations as to
the validity or sufficiency of this Indenture or the Securities. Neither the
Trustee nor any Authenticating Agent shall be accountable for the use or
application by the Corporation of Securities or the proceeds thereof.

                                       38
<PAGE>
SECTION 605. TRUSTEE MAY HOLD SECURITIES.

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

SECTION 606. MONEY HELD IN TRUST.

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

SECTION 607. COMPENSATION, REIMBURSEMENT, INDEMNIFICATION.

      The Corporation agrees as follows:

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

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

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

      If any action, suit or proceeding is brought against any Trustee in
connection with any claim for which it is entitled to indemnity hereunder, it
shall promptly (but no later than ten days following service) notify the
Corporation in writing enclosing a copy of all papers served. All counsel
employed to defend any such claim shall be retained directly by the Corporation
and may serve as counsel to the Corporation and/or one or more Trustees. Absent
a conflict of interest, the Corporation shall not be required to pay the fees
and expenses of more than one law firm in connection with its obligations
hereunder. A Trustee entitled to indemnification may, in addition to counsel
engaged by the Corporation, engage counsel to represent such party at that
party's sole expense. Notwithstanding any other provision of this Indenture, the
Corporation shall not be liable

                                       39
<PAGE>
to pay any settlement agreed to without its written consent.

SECTION 608. CONFLICTING INTERESTS.

      If the Trustee has or shall acquire a conflicting interest within the
meaning of the Trust Indenture Act, the Trustee shall either eliminate such
interest or resign, to the extent and in the manner provided by, and subject to
the provisions of, the Trust Indenture Act and this Indenture. To the extent
permitted by the Trust Indenture Act, the Trustee shall not be deemed to have a
conflicting interest by virtue of being a trustee under this Indenture with
respect to Securities of more than one series or a trustee under the indenture
dated July 27, 2001 between the Corporation and the Trustee.

SECTION 609. CORPORATE TRUSTEE REQUIRED; ELIGIBILITY.

      There shall at all times be one (and only one) Trustee hereunder with
respect to the Securities of each series, which may be Trustee hereunder for
Securities of one or more other series. Each Trustee shall be a Person that is
eligible pursuant to the Trust Indenture Act to act as such and has a combined
capital and surplus of at least $50,000,000. If any such Person publishes
reports of condition at least annually, pursuant to law or to the requirements
of its supervising or examining authority, then for the purposes of this Section
and to the extent permitted by the Trust Indenture Act, 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 with respect to the Securities of any series shall cease to be
eligible in accordance with the provisions of this Section, it shall resign
immediately in the manner and with the effect hereinafter specified in this
Article.

SECTION 610. RESIGNATION AND REMOVAL; APPOINTMENT OF SUCCESSOR.

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

      (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 611 shall not have been delivered to the Trustee
            within 30 days after the giving of such notice of resignation, the
            resigning Trustee may petition any court of competent jurisdiction
            for the appointment of a successor Trustee with respect to the
            Securities of such series.

      (c)   The Trustee may be removed at any time with respect to the
            Securities of any series by Act of the Holders of a majority in
            principal amount of the Outstanding Securities of such series,
            delivered to the Trustee and to the Corporation. If the instrument
            of acceptance by a successor Trustee required by Section 611 shall
            not have been delivered to the Trustee within 30 days after the
            giving of such notice of removal, the Trustee being removed may

      (d)   If at any time:

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

            (2)   the Trustee shall cease to be eligible under Section 609 and
                  shall fail to resign after written request therefor by the
                  Corporation or by any such Holder, or

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

then, in any such case,

                  (A)   the Corporation by a Board Resolution may remove the
                        Trustee with respect to all Securities, or

                  (B)   subject to Section 514, any Holder who has been a bona
                        fide Holder of a Security for at least six months may,
                        on behalf of himself and all others similarly situated,
                        petition any court of competent jurisdiction for the
                        removal of the Trustee with respect to all Securities
                        and the appointment of a successor Trustee or Trustees.

      (e)   If the Trustee shall resign, be removed or become incapable of
            acting, or if a vacancy shall occur in the office of Trustee for any
            cause, with respect to the Securities of one or 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 particular series) and
            shall comply with the applicable requirements of Section 611. If,
            within one year after such resignation, removal or incapability, or
            the occurrence of such vacancy, a successor Trustee with respect to
            the Securities of any series shall be appointed by Act of the
            Holders of a majority in principal amount of the Outstanding
            Securities of such series delivered to the 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 611, 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
            shall have been so appointed by the Corporation or the Holders and
            accepted appointment in the manner required by Section 611, 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

                                       41
<PAGE>
            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 to all Holders of Securities of such series
            in the manner provided in Section 106. Each notice shall include the
            name of the successor Trustee with respect to the Securities of such
            series and the address of its Corporate Trust Office.

SECTION 611. ACCEPTANCE OF APPOINTMENT BY SUCCESSOR.

      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, and thereupon the resignation or removal
of the retiring Trustee shall become effective and such successor Trustee,
without any further act, deed or conveyance, shall become vested with all the
rights, powers, trusts and duties of the retiring Trustee; but, on the request
of the 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.

      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 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

                                       42
<PAGE>
money held by such retiring Trustee hereunder with respect to the Securities of
that or those series to which the appointment of such successor Trustee relates.

      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 the
first or second preceding paragraph, as the case may be.

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

SECTION 612. MERGER, CONVERSION, CONSOLIDATION OR SUCCESSION TO BUSINESS.

      Any corporation into which the Trustee may be merged or converted or with
which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
corporation succeeding to all or substantially all the corporate trust business
of the Trustee, shall be the successor of the Trustee hereunder, provided such
corporation shall be otherwise qualified and eligible under this Article,
without the execution or filing of any paper or any further act on the part of
any of the parties hereto. In case any Securities shall have been authenticated,
but not delivered, by the Trustee then in office, any successor by merger,
conversion or consolidation to such authenticating Trustee may adopt such
authentication and deliver the Securities so authenticated with the same effect
as if such successor Trustee had itself authenticated such Securities.

SECTION 613. PREFERENTIAL COLLECTION OF CLAIMS AGAINST CORPORATION.

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

SECTION 614. APPOINTMENT OF AUTHENTICATING AGENT.

      The Trustee may appoint an Authenticating Agent or Agents with respect to
one or more series of Securities which shall be authorized to act on behalf of
the Trustee to authenticate Securities of such series issued upon original issue
and upon exchange, registration of transfer or partial redemption thereof or
pursuant to Section 306, 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 must 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 of not less than
$50,000,000 and subject to supervision or examination by Federal or State
authority. If such Authenticating Agent publishes reports of condition at least
annually, pursuant to law or to the requirements of said

                                       43
<PAGE>
supervising or examining authority, then for the purposes of this Section, the
combined capital and surplus of such Authenticating Agent shall be deemed to be
its combined capital and surplus as set forth in its most recent report of
condition so published. If at any time an Authenticating Agent shall cease to be
eligible in accordance with the provisions of this Section, such Authenticating
Agent shall resign immediately in the manner and with the effect specified in
this Section.

      Any corporation into which 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 all or substantially all of
the corporate agency or corporate trust business of an Authenticating Agent,
shall continue to be an Authenticating Agent, provided such corporation shall be
otherwise eligible under this Section, without the execution or filing of any
paper or any further act on the part of the Trustee or the Authenticating Agent.

      In case at the time such successor to any Authenticating Agent with
respect to any series shall succeed to such Authenticating Agent, any of the
Securities of such series shall have been authenticated but not delivered, any
such successor to such Authenticating Agent may adopt the certificate of
authentication of any predecessor Authenticating Agent and deliver such
Securities so authenticated; and in case at that time any of the Securities of
such series shall not have been authenticated, any successor to any
Authenticating Agent may authenticate such Securities either in the name of any
predecessor hereunder or in the name of successor Authenticating Agent; and in
all such cases such certificate shall have the full force which it is anywhere
in the Securities of such series or in this Indenture provided that the
certificate of the predecessor Authenticating Agent shall have; provided,
however, that the right to adopt the certificate of authentication of any
predecessor Authenticating Agent or to authenticate Securities in the name of
any predecessor Authenticating Agent shall apply only to its successor or
successors by merger, conversion or consolidation.

      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 a termination, or in case at any time such
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, the Trustee may appoint a successor Authenticating
Agent which must be acceptable to the Corporation and shall give notice of such
appointment in the manner provided in Section 106 to all Holders of Securities
of the series with respect to which such Authenticating Agent will serve. Any
successor Authenticating Agent upon acceptance of its appointment hereunder
shall become vested with all the rights, powers and duties of its predecessor
hereunder, with like effect as if originally named as an Authenticating Agent.
No successor Authenticating Agent shall be appointed unless eligible under the
provisions of this Section.

      Any Authenticating Agent by the acceptance of its appointment shall be
deemed to have agreed with the Trustee that: it will perform and carry out the
duties of an Authenticating Agent as herein set forth; it will keep and maintain
and furnish to the Trustee from time to time as requested by the Trustee
appropriate records of all transactions carried out by it as Authenticating
Agent and will furnish the Trustee such other information and reports as the
Trustee may reasonably require; it is eligible for

                                       44
<PAGE>
appointment as Authenticating Agent under this Section 614 and will notify the
Trustee promptly if it shall cease to be so qualified; and it will indemnify the
Trustee against any loss, liability or expense incurred by the Trustee and will
defend any claim asserted against the Trustee by reason of acts or failures to
act of the Authenticating Agent but it shall have no liability for any action
taken by it at the specific written direction of the Trustee.

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

      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 alternative
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.

addresses of Holders received by the Trustee, or its designee, in its capacity

other Person or sell or convey all or substantially all of its assets to any
Person, except that the Corporation may merge or consolidate with, or sell or
convey all or substantially all of its assets to, any other Person, provided
that

      (1)   (a)   the Corporation shall be the continuing Person or

            (b)   (i) the successor Person (if other than the Corporation) shall
                  be a Person organized and existing under the laws of the
                  United States of America or a State thereof and

                  (ii)  such Person shall expressly assume the due and punctual
                        payment of the principal of and any premium and interest

                        the covenants and conditions of this Indenture to be
                        performed by the Corporation

and

      (2)   the Corporation or such successor Person, as the case may be, shall

            conveyance, be in default in the performance of any such covenant or
            condition and no event which with the lapse of time, the giving of
            notice or both would constitute an Event of Default shall have
            occurred and be continuing.

      For purposes of this Section 801, "substantially all of its assets" shall

had been named herein as a party hereto, and the Corporation shall thereupon be
relieved of any further obligations or liabilities hereunder and upon the
Securities and the Corporation as the predecessor Person may thereupon or at any
time thereafter be dissolved, wound-up or liquidated. Such successor Person
thereupon may cause to be signed, and may issue either in its own name or in the
name of the predecessor corporation, any or all of the Securities issuable

delivered to the Trustee and, upon the order of such successor Person, instead
of the Corporation, and subject to all the terms, conditions and limitations in

Securities which previously shall have been signed and delivered by the officers
of the Corporation to the Trustee for authentication and any Securities which
such successor Person thereafter shall cause to be signed and delivered to the
Trustee for that purpose. All the Securities so issued shall in all respects
have the same legal rank and benefit under this Indenture as the Securities
theretofore or thereafter issued in accordance with the terms of this Indenture
as though all of such Securities had been issued at the date of the execution
hereof.

in phraseology and form (but not in substance) may be made in the Securities
thereafter to be issued as may be appropriate.

                        execution of such supplemental indenture and entitled to
                        the benefit of such provision nor

                  Outstanding;

      or

      (6)   to secure the Securities of any series; or

      (7)   to establish the form or terms of Securities of any series as
            permitted by Sections 201 and 301; or

      (8)   to evidence and provide for the acceptance of appointment hereunder
            by a successor Trustee with respect to the Securities of one or more
            series and to add to or change any of the provisions of this
            Indenture as shall be necessary to provide for or facilitate the
            administration of the trusts hereunder by more than one Trustee,
            pursuant to the requirements of Section 611; or

      (9)   to make provision with respect to any conversion or exchange rights
            contemplated by Section 301; or

      (10)  to cure any ambiguity, to correct or supplement any provision herein
            which may be defective or inconsistent with any other provision

            of the Holders of Securities of any series in any material respect;
            or

      (12)  to add, change or eliminate any provision of this Indenture as shall
            be necessary or desirable in accordance with any amendments to the
            Trust Indenture Act.

SECTION 902. SUPPLEMENTAL INDENTURES WITH CONSENT OF HOLDERS.

      With the consent of the Holders of not less than a majority in principal
amount of the Outstanding Securities of each series affected by such
supplemental indenture, by Act of said Holders delivered to the Corporation and
the Trustee, the Corporation, when authorized by its Board of Directors, and the
Trustee may enter into an indenture or indentures supplemental hereto for the
purpose of adding any provisions to or changing in any manner or eliminating any
of the provisions of this Indenture or of modifying in any

                                       49
<PAGE>
manner the rights of the Holders of Securities of such series under this
Indenture; provided, however, that no such supplemental indenture shall, without
the consent of the Holder of each Outstanding Security affected thereby,

      (1)   change the Stated Maturity of the principal of, or any installment
            of principal of or interest or premium on, any Security, or reduce
            the principal amount thereof or the rate of interest thereon or any
            premium payable upon the redemption thereof, or reduce the amount of
            the principal of an Original Issue Discount Security or any other
            Security which would be due and payable upon a declaration of
            acceleration of the Maturity thereof pursuant to Section 502, or
            change the coin or currency in which any Security or any premium or
            interest thereon is payable, or impair the right to institute suit
            for the enforcement of any such payment on or after the Stated
            Maturity thereof (or, in the case of redemption, on or after the
            Redemption Date), or adversely affect any right of the Holder of any
            Security to require the Corporation to repurchase such Security

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

      (3)   modify any of the provisions of this Section, Section 513 or Section
            1005, except to increase any percentage set forth in such Sections
            or to provide that certain other provisions of this Indenture cannot
            be modified or waived without the consent of the Holder of each
            Outstanding Security affected thereby; provided, however, that this
            clause shall not be deemed to require the consent of any Holder with
            respect to changes in the references to "the Trustee" and
            concomitant changes in this Section and Section 1005.

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

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

SECTION 903. EXECUTION OF SUPPLEMENTAL INDENTURES.

      In executing, or accepting the additional trusts created by, any
supplemental indenture permitted by this Article or the modifications thereby of
the trusts created by this Indenture, the Trustee shall be entitled to receive,
and (subject to Section 601) shall be fully protected in relying upon, an
Opinion of Counsel stating that the execution of such supplemental indenture is
authorized or permitted by this Indenture. The Trustee

                                       50
<PAGE>
may, but shall not be obligated to, enter into any such supplemental indenture
which affects the Trustee's own rights, duties or immunities under this
Indenture or otherwise.

SECTION 904. EFFECT OF SUPPLEMENTAL INDENTURES.

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

SECTION 905. CONFORMITY WITH TRUST INDENTURE ACT.

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

SECTION 906. 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 1001. PAYMENT OF PRINCIPAL, PREMIUM AND INTEREST.

      The Corporation covenants and agrees for the benefit of each series of
Securities that it will duly and punctually pay or cause to be paid the
principal of (including any amount in respect of original issue discount) and
any premium and interest on each of the Securities of such series at the Place
of Payment, at the respective times and in the manner provided in the Securities
and this Indenture. The principal of, premium, and interest on the Securities
shall be payable only in accordance with the terms of the relevant Security.

SECTION 1002. MAINTENANCE OF OFFICE OR AGENCY.

      The Corporation will maintain 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 the Corporation in respect of the Securities of
that series and this Indenture may be served. The Corporation will give prompt
written notice to the Trustee of the location, and any change in the location,
of such office or agency. If at any time the Corporation shall fail to maintain
any such required office or agency or shall fail to furnish the Trustee with the
address thereof, such presentations, surrenders, notices and demands may be made
or served at the Corporate Trust Office of the Trustee, or an affiliate of the
Trustee, and the Corporation hereby appoints the Trustee as its agent to receive
all such

                                       51
<PAGE>
presentations, surrenders, notices and demands.

      The Corporation may also from time to time designate one or more other
offices or agencies where the Securities of one or more series may be presented
or surrendered for any or all such purposes and may from time to time rescind
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 for such purposes. The Corporation will give prompt written
notice to the Trustee of any such designation or rescission and of any change in
the location of any such other office or agency.

SECTION 1003. MONEY FOR SECURITIES PAYMENTS TO BE HELD IN TRUST.

      If the Corporation shall at any time act as its own Paying Agent with
respect to any series of Securities, it will, on or before each due date of the
principal of or any premium or interest on any of the Securities of that series,
segregate and hold in trust for the benefit of the Persons entitled thereto a
sum sufficient to pay the principal and any premium and interest so becoming due
until such sums shall be paid to such Persons or otherwise disposed of as herein
provided and will promptly notify the Trustee of its action or failure so to
act.

      Whenever the Corporation shall have one or more Paying Agents for any
series of Securities, it will, prior to each due date of the principal of or any
premium or interest on any Securities of that series, deposit with a Paying
Agent a sum sufficient to pay such amount, such sum to be held as provided by
the Trust Indenture Act, and (unless such Paying Agent is the Trustee) the
Corporation will promptly notify the Trustee of its action or failure so to act.

      The Corporation will cause each Paying Agent, other than the Trustee or
the Corporation, for any series of Securities to execute and deliver to the
Trustee an instrument in which such Paying Agent shall agree with the Trustee,
subject to the provisions of this Section, that such Paying Agent will (1)
comply with the provisions of the Trust Indenture Act applicable to it as a
Paying Agent and (2) during the continuance of any default by the Corporation
(or any other obligor upon the Securities of that series) in the making of any
payment in respect of the Securities of that series, upon the written request of
the Trustee, forthwith pay to the Trustee all sums held in trust by such Paying
Agent for payment in respect of the Securities of that series. Each of the
Corporation and the Trustee, having agreed to the foregoing on its behalf as a
Paying Agent by its execution and delivery of this instrument, has hereby
satisfied the provisions of this paragraph with respect to itself 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 Corporation Order 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 or any premium or
interest on any

                                       52
<PAGE>
Security of any series and remaining unclaimed for two years after such
principal, premium or interest has become due and payable shall be paid to the
Corporation on Corporation Request, or (if then held by the Corporation) shall
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 New York, 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 will be
repaid to the Corporation free of the trust formerly impressed upon it.

SECTION 1004. STATEMENT BY OFFICERS AS TO DEFAULT.

      The Corporation will 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, stating whether or not to the best knowledge of the
signers thereof the Corporation is in default in the performance and observance
of any of the terms, provisions and conditions of this Indenture (without regard
to any period of grace or requirement of notice provided hereunder) and, if the
Corporation shall be in default, specifying all such defaults and the nature and
status thereof of which they may have knowledge.

<PAGE>

SECTION 1005. WAIVER OF CERTAIN COVENANTS.

      Except as otherwise specified as contemplated by Section 301 for
Securities of such series, the Corporation may, with respect to the Securities
of any series, omit in any particular instance to comply with any term,
provision or condition set forth in any covenant provided pursuant to Section
301(18), 901(2) or 901(7) for the benefit of the Holders of such series if
before the time for such compliance the Holders of at least a majority in
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 term, provision or condition, but no such waiver shall
extend to or affect such term, provision or condition except to the extent so
expressly waived, and, until such waiver shall become effective, the obligations
of the Corporation and the duties of the Trustee in respect of any such term,
provision or condition shall remain in full force and effect.

                                 ARTICLE ELEVEN
                            REDEMPTION OF SECURITIES

SECTION 1101. 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 301 for such Securities) in accordance with
this Article.

SECTION 1102. ELECTION TO REDEEM; NOTICE TO TRUSTEE.

      The election of the Corporation to redeem any Securities shall be
evidenced by a

                                       54
<PAGE>
Board Resolution or in another manner specified as contemplated by Section 301
for such Securities. In case of any redemption at the election of the
Corporation of less than all the Securities of any series (including any such
redemption affecting only a single Security), 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 of such
Redemption Date, of the principal amount of Securities of such series to be
redeemed and, if applicable, of the tenor of the Securities to be redeemed. In
the case of any redemption of Securities prior to the expiration of any
restriction on such redemption provided in the terms of such Securities or
elsewhere in this Indenture, the Corporation shall furnish the Trustee with an
Officers' Certificate evidencing compliance with such restriction.

SECTION 1103. SELECTION BY TRUSTEE OF SECURITIES TO BE REDEEMED.

      If less than all the Securities of any series are to be redeemed (unless
all the Securities of such series and of a specified tenor are to be redeemed or
unless such redemption affects only a single Security), the particular
Securities to be redeemed shall be selected not more than 60 days prior to the
Redemption Date by the Trustee, from the Outstanding Securities of such series
not previously called for redemption, by such method as the Trustee shall deem
fair and appropriate and which may provide for the selection for redemption of a
portion of the principal amount of any Security of such series, provided that
the unredeemed portion of the principal amount of any Security shall be in an
authorized denomination (which shall not be less than the minimum authorized
denomination or any integral multiple thereof) for such Security. If less than
all the Securities of such series and of a specified tenor are to be redeemed
(unless such redemption affects only a single Security), 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
and specified tenor not previously called for redemption in accordance with the
preceding sentence.

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

      The provisions of the two preceding paragraphs shall not apply with
respect to any redemption affecting only a single Security, whether such
Security is to be redeemed in whole or in part. In the case of any such
redemption in part, the unredeemed portion of the principal amount of the
Security shall be in an authorized denomination (which shall not be less than
the minimum authorized denomination) for such Security.

      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 1104. NOTICE OF REDEMPTION.

      Notice of redemption shall be given by first-class mail, postage prepaid,
mailed not less than 30 nor more than 60 days prior to the Redemption Date, to
each Holder of Securities to be redeemed, at his address appearing in the
Security Register.

                                       55
<PAGE>
      All notices of redemption shall state:

      (1)   the Redemption Date,

      (2)   the Redemption Price,

      (3)   if less than all the Outstanding Securities of any series consisting
            of more than a single Security are to be redeemed, the
            identification (and, in the case of partial redemption of any such
            Securities, the principal amounts) of the particular Securities to
            be redeemed and, if less than all the Outstanding Securities of any
            series consisting of a single Security are to be redeemed, the
            principal amount of the particular Security to be redeemed,

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

      (5)   the place or places where each such Security is to be surrendered
            for payment of the Redemption Price, and

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

      (7)   if applicable, the conversion price or exchange rate, the date on
            which the right to convert or exchange the Securities to be redeemed
            shall terminate and the place or places where such Securities may be
            surrendered for conversion or exchange, as the case may be.

      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 and shall be
irrevocable.

SECTION 1105. DEPOSIT OF REDEMPTION PRICE.

      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 1003) an amount
of money sufficient to pay the Redemption Price of, and (except if the
Redemption Date shall be an Interest Payment Date) accrued interest on, all the
Securities which are to be redeemed on that date.

SECTION 1106. SECURITIES PAYABLE ON REDEMPTION DATE.

      Notice of redemption having been given as aforesaid, the Securities so to
be redeemed shall, on the Redemption Date, become due and payable at the
Redemption Price therein specified, and from and after such date (unless the
Corporation shall default in the payment of the Redemption Price and accrued
interest) such Securities shall cease to bear interest. Upon surrender of any
such Security for redemption in accordance with said notice, such Security shall
be paid by the Corporation at the Redemption Price, together with accrued
interest to the Redemption Date; provided, however, that, unless otherwise
specified as contemplated by Section 301, installments of interest whose Stated
Maturity is on or prior to the Redemption Date will be payable to the Holders of
such Securities, or one or more Predecessor Securities, registered as such at
the close of business on the relevant Record Dates according to their terms and
the provisions of Section 307.

      If any Security called for redemption shall not be so paid upon surrender
thereof

                                       56
<PAGE>
for redemption, the principal and any premium shall, until paid, bear interest
from the Redemption Date at the rate prescribed therefor in the Security.

SECTION 1107. SECURITIES REDEEMED IN PART.

      Any Security that 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,
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 and of like
tenor, of any authorized denomination as requested by such Holder, in aggregate
principal amount equal to and in exchange for the unredeemed portion of the
principal of the Security so surrendered.

                                 ARTICLE TWELVE
                                  SINKING FUNDS

SECTION 1201. APPLICABILITY OF ARTICLE.

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

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

SECTION 1202. SATISFACTION OF SINKING FUND PAYMENTS WITH SECURITIES.

      The Corporation

      (1)   may deliver Outstanding Securities of a series (other than any
            previously called for redemption) 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 any Securities of such series required to be made pursuant to the
terms of such Securities as and to the extent provided for by the terms of such
Securities; provided that the Securities to be so credited have not been
previously so credited. The Securities to be so credited shall be received and
credited for such purpose by the Trustee at the Redemption Price, as specified
in the Securities so to be redeemed, for redemption through operation of the
sinking fund and the amount of such sinking fund

                                       57
<PAGE>
payment shall be reduced accordingly.

SECTION 1203. REDEMPTION OF SECURITIES FOR SINKING FUND.

      Not less than 45 days prior to each sinking fund payment date for any
Securities, the Corporation will deliver to the Trustee an Officers' Certificate
specifying the amount of the next ensuing sinking fund payment for such
Securities pursuant to the terms of such Securities, 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 pursuant to
Section 1202 and will also deliver to the Trustee any Securities to be so
delivered. Not less than 15 nor more than 45 days prior to each such sinking
fund payment date, the Trustee shall select the Securities to be redeemed upon
such sinking fund payment date in the manner specified in Section 1103 and cause
notice of the redemption thereof to be given in the name of and at the expense
of the Corporation in the manner provided in Section 1104. Such notice having
been duly given, the redemption of such Securities shall be made upon the terms
and in the manner stated in Sections 1106 and 1107.

                                ARTICLE THIRTEEN
                                   DEFEASANCE

SECTION 1301. CORPORATION'S OPTION TO EFFECT DEFEASANCE.

      The Corporation may elect, at its option at any time, to have Section 1302
or Section 1303 applied to any Securities or any series of Securities, as the
case may be, designated pursuant to Section 301 as being defeasible pursuant to
such Section 1302 or 1303, in accordance with any applicable requirements
provided pursuant to Section 301 and upon compliance with the conditions set
forth in this Article. Any such election shall be evidenced by a Board
Resolution or in another manner specified as contemplated by Section 301 for
such Securities.

SECTION 1302. DEFEASANCE AND DISCHARGE.

      Upon the Corporation's exercise of its option (if any) to have this
Section applied to any Securities or any series of Securities, as the case may
be, the Corporation shall be deemed to have been discharged from its obligations
with respect to such Securities as provided in this Section on and after the
date the conditions set forth in Section 1304 are satisfied (a "Defeasance").
Defeasance means that the Corporation shall be deemed to have paid and
discharged the entire indebtedness represented by such Securities and to have
satisfied all its other obligations under such Securities and this Indenture
insofar as such Securities are concerned (and the Trustee, at the expense of the
Corporation, shall execute proper instruments acknowledging the same), subject
to the following which shall survive until otherwise terminated or discharged
hereunder:

      (1)   The rights of Holders of such Securities to receive, solely from the
            trust fund described in Section 1304 and as more fully set forth in
            such Section, payments in respect of the principal of and any
            premium and interest on such Securities when payments are due,

      (2)   The Corporation's obligations with respect to such Securities under
            Sections 304, 305, 306, 1002 and 1003,

                                       58
<PAGE>
      (3)   The rights, powers, trusts, duties and immunities of the Trustee
            hereunder and

      (4)   This Article.

      Subject to compliance with this Article, the Corporation may exercise its
option (if any) to have this Section applied to any Securities notwithstanding
the prior exercise of its option (if any) to have Section 1303 applied to such
Securities.

SECTION 1303. COVENANT DEFEASANCE.

      Upon the Corporation's exercise of its option (if any) to have this
Section applied to any Securities or any series of Securities, as the case may
be,

      (1)   the Corporation shall be released from its obligations under Section
            801, Section 803, and any such covenants provided pursuant to
            Section 301(18), 901(2) or 901(6) for the benefit of the Holders of
            such Securities, and

      (2)   the occurrence of any event specified in Sections 501(3), 501(4)
            (with respect to any of Section 801, Section 803, and any such
            covenants provided pursuant to Section 301(18), 901(2) or 901(6))
            and 501(8) shall be deemed not to be or result in an Event of
            Default,

      (3)   the provisions of Article Fourteen shall cease to be effective.

in each case with respect to such Securities as provided in this Section on and
after the date the conditions set forth in Section 1304 are satisfied
(hereinafter called "Covenant Defeasance"). For this purpose, such Covenant
Defeasance means that, with respect to such Securities, the Corporation may omit
to comply with and shall have no liability in respect of any term, condition or
limitation set forth in any such specified Section (to the extent so specified
in the case of Section 501(4) or Article Fourteen), whether directly or
indirectly by reason of any reference elsewhere herein to any such Section or by
reason of any reference in any such Section to any other provision herein or in
any other document, but the remainder of this Indenture and such Securities
shall be unaffected thereby.

                  and interest in respect thereof in accordance with their terms
                  will provide, not later than one day before the due date of

                  due date of any payment, money in an amount, or

   principal of and any premium and interest on such Securities on the
   respective Stated Maturities, in accordance with the terms of this Indenture
   and such Securities.

      (2)   In the event of an election to have Section 1302 apply to any
            Securities or any series of Securities, as the case may be, the
            Corporation shall have delivered to the Trustee an Opinion of
            Counsel stating that

            (A)   the Corporation has received from, or there has been published
                  by, the Internal Revenue Service a ruling or

            (B)   since the date of this instrument, there has been a change in
                  the applicable Federal income tax law,

   in either case (A) or (B) to the effect that, and based thereon such opinion
   shall confirm that, the Holders of such Securities will not recognize gain or
   loss for Federal income tax purposes as a result of the deposit, Defeasance
   and discharge to be effected with respect to such Securities and will be
   subject to Federal income tax on the same amount, in the same manner and at
   the same times as would be the case if such deposit, Defeasance and discharge
   were not to occur.

      (3)   In the event of an election to have Section 1303 apply to any
            Securities or any series of Securities, as the case may be, the
            Corporation shall have delivered to the Trustee an Opinion of
            Counsel to the effect that the Holders of such Securities will not
            recognize gain or loss for Federal income tax purposes as a result
            of the deposit and Covenant Defeasance to be effected with respect
            to such Securities and will be subject to Federal income tax on the
            same amount, in the same manner and at the same times as would be
            the case if such deposit and Covenant Defeasance were not to occur.

      (4)   No event which is, or after notice or lapse of time or both would
            become,

                                       60
<PAGE>
            an Event of Default with respect to such Securities or any other
            Securities shall have occurred and be continuing at the time of such
            deposit or, with regard to any such event specified in Sections
            501(5) and (6), at any time on or prior to the 90th day after the
            date of such deposit (it being understood that this condition shall
            not be deemed satisfied until after such 90th day).

      (5)   Such Defeasance or Covenant Defeasance shall not cause the Trustee
            to have a conflicting interest within the meaning of the Trust
            Indenture Act (assuming all Securities are in default within the
            meaning of such Act).

      (6)   Such Defeasance or Covenant Defeasance shall not result in a breach
            or constitute a default under, any other agreement or instrument to
            which the Corporation is a party or by which it is bound.

      (7)   Such Defeasance or Covenant Defeasance shall not result in the trust
            arising from such deposit constituting an investment company within
            the meaning of the Investment Corporation Act of 1940 (and any
            statute successor thereto) unless such trust shall be registered
            under such Act or exempt from registration thereunder.

      (8)   At the time of such deposit, (A) no default in the payment of any
            principal of or premium or interest on any Senior Debt shall have
            occurred and be continuing, (B) no event of default with respect to
            any Senior Debt shall have resulted in such Senior Debt becoming,
            and continuing to be, due and payable prior to the date on which it
            would otherwise have become due and payable (unless payment of such
            Senior Debt has been made or duly provided for), and (C) no other
            event of default with respect to any Senior Debt shall have occurred
            and be continuing permitting (after notice or lapse of time or both)
            the holders of such Senior Debt (or a trustee on behalf of such
            holders) to declare such Senior Debt due and payable prior to the
            date on which it would otherwise have become due and payable.

      (9)   The Corporation shall have delivered to the Trustee an Officer's
            Certificate and an Opinion of Counsel, each stating that all
            conditions precedent with respect to such Defeasance or Covenant
            Defeasance have been complied with.

SECTION 1305. DEPOSITED MONEY, U.S. GOVERNMENT OBLIGATIONS AND DEFEASED
MUNICIPAL OBLIGATIONS TO BE HELD IN TRUST; MISCELLANEOUS PROVISIONS.

      Subject to the provisions of the last paragraph of Section 1003, all
money, U.S. Government Obligations (including the proceeds thereof), Defeased
Municipal Obligations (including the proceeds thereof) and Foreign Government
Obligations (including the proceeds thereof) deposited with the Trustee or other
qualifying trustee (solely for purposes of this Section and Section 1306, the
Trustee and any such other trustee are referred to collectively as the
"Trustee") pursuant to Section 1304 in respect of any Securities shall be held
in trust and applied by the Trustee, in accordance with the provisions of such
Securities and this Indenture, to the payment, either directly or through any
such Paying Agent (including the Corporation acting as its own Paying Agent) as
the Trustee may determine, to the Holders of such Securities, of all sums due
and to become due thereon in respect of principal and any premium and interest,
but money so held in trust need not be segregated from other funds except to the
extent required by law.

      The Corporation shall pay and indemnify the Trustee against any tax, fee
or other charge imposed on or assessed against the U.S. Government Obligations
and Foreign Government Obligations deposited pursuant to Section 1304 or the
principal and interest received in respect thereof other than any such tax, fee
or other charge which by law is for the account of the Holders of Outstanding
Securities.

      Anything in this Article to the contrary notwithstanding, the Trustee
shall deliver or pay to the Corporation from time to time upon Corporation
Request any money, U.S.

                                       61
<PAGE>
Government Obligations, Defeased Municipal Obligations or Foreign Government
Obligations held by it as provided in Section 1304 with respect to any
Securities that, in the opinion of a nationally recognized firm of independent
public accountants expressed in a written certification thereof delivered to the
Trustee, are in excess of the amount thereof which would then be required to be
deposited to effect the Defeasance or Covenant Defeasance, as the case may be,
with respect to such Securities.

SECTION 1306. REINSTATEMENT.

      If the Trustee or the Paying Agent is unable to apply any money in
accordance with this Article with respect to any Securities by reason of any
order or judgment of any court or governmental authority enjoining, restraining
or otherwise prohibiting such application, then the obligations under this
Indenture and such Securities from which the Corporation has been discharged or
released pursuant to Section 1302 or 1303 shall be revived and reinstated as
though no deposit had occurred pursuant to this Article with respect to such
Securities, until such time as the Trustee or Paying Agent is permitted to apply
all money held in trust pursuant to Section 1305 with respect to such Securities
in accordance with this Article; provided, however, if the Corporation makes any
payment of principal of or any premium or interest on any such Security
following such reinstatement of its obligations, the Corporation shall be
subrogated to the rights (if any) of the Holders of such Securities to receive
such payment from the money so held in trust.

                                ARTICLE FOURTEEN

                          SUBORDINATION OF SECURITIES

SECTION 1401. SECURITIES SUBORDINATE TO SENIOR DEBT.

      The Corporation covenants and agrees, and each Holder of Securities of
any series by the Holder's acceptance thereof, likewise covenants and agrees,
that, to the extent and in the manner hereinafter set forth in this Article,
subject to the provisions of Article Four and Article Thirteen and except as may
otherwise be specified as contemplated by Section 301 and set forth in the
Securities of a series, the indebtedness represented by the Securities of such
series and the payment of the principal of and any premium and interest on each
and all of the Securities of such series are hereby expressly made subordinate
and junior in right of payment to the prior payment in full of all amounts then
due and payable in respect of all Senior Debt of the Corporation, to the extent
and in the manner herein set forth (unless a different manner is set forth in
the Securities of such series). No provision of this Article shall prevent the
occurrence of any default or Event of Default hereunder.

      Senior Debt shall not be deemed to have been paid in full unless the
holders thereof shall have received cash, securities or other property equal to
the amount of such Senior Debt then outstanding.

SECTION 1402. PAYMENT OVER OF PROCEEDS UPON DISSOLUTION, ETC.

      In the event of:

              (i)     any insolvency, bankruptcy, receivership, liquidation,

                                       62
<PAGE>
                        reorganization, readjustment, composition or other
                        similar proceeding relating to the Corporation, its
                        creditors or its property,

              (ii)      any proceeding for the liquidation, dissolution or other
                        winding up of the Corporation, whether voluntary or
                        involuntary, or bankruptcy proceedings,

              (iii)     any assignment by the Corporation for the benefit of its
                        creditors,

              (iv)      any other marshalling of the assets of the Corporation,

all Senior Debt shall first be paid in full before any payment or distribution,
whether in cash, securities or other property, shall be made by the Corporation
on account of the Securities of any series. Any payment or distribution, whether
in cash, securities or other property (other than securities of the Corporation
or any other corporation provided for by a plan or reorganization or a
readjustment, the payment of which is subordinate, at least to the extent
provided in these subordination provisions with respect to the indebtedness
evidenced by the Securities of any series, to the payment of all Senior Debt at
the time outstanding and to any securities issued in respect thereof under any
such plan of reorganization or readjustment), which would otherwise (but for
these subordination provisions) be payable or deliverable in respect to the
Securities of any series shall be paid or delivered directly to the holders of
Senior Debt in accordance with the priorities then existing among such holders
until all Senior Debt shall have been paid in full. No present or future holder
of any Senior Debt shall be prejudiced in the right to enforce subordination of
the indebtedness constituting the Securities of any series by any act of failure
to act on the part of the Corporation.

SECTION 1403. NO PAYMENT WHEN SENIOR DEBT IN DEFAULT.

         In the event that:

              (i)       the Corporation shall default in the payment of any
                        principal, or premium, if any, or interest on any Senior
                        Debt when the same becomes due and payable, whether at
                        maturity or at a date fixed for prepayment or
                        declaration or otherwise; or

              (ii)      an event of default occurs with respect to any Senior
                        Debt permitting the holders thereof to accelerate the
                        maturity thereof and written notice describing such
                        event of default and requesting commencement of payment
                        blockage on transactions as thereinafter described is
                        given to the Corporation by the holders of Senior Debt,

then unless and until such default in payment and event of default shall have
been cured or waived or shall have ceased to exist, no direct or indirect
payment (in cash, property, securities, by set-off of otherwise) shall be made
or agreed to be made on account of the Securities of any series or any interest
thereon in respect of any repayment, redemption, retirement, purchase or other
acquisition of the Securities of any series.

                                       63
<PAGE>
SECTION 1404. PAYMENT PERMITTED IN CERTAIN SITUATIONS.

         Nothing contained in this Article or elsewhere in this Indenture
or in any of the Securities of any series shall prevent

              (a)       the Corporation, at any time except during the pendency
                        of any dissolution, winding-up, liquidation or
                        reorganization of the Corporation, whether voluntary or
                        involuntary or any bankruptcy, insolvency, receivership
                        or other proceedings of the Corporation referred to in
                        Section 1402 or under the conditions described in
                        Section 1403, from making payments at any time of
                        principal of, or premium, if any, or interest on the
                        Securities of such series, or

              (b)       the application by the Trustee of any money deposited
                        with it hereunder to the payment of or on account of
                        the principal of, or premium, if any, or interest on
                        the Securities of such series or the retention of such
                        payment by the Holders, if, at the time of such
                        application by the Trustee, it did not have knowledge
                        that such payment would have been prohibited by the
                        provisions of this Article.

SECTION 1405. SUBROGATION TO RIGHTS OF HOLDERS OF SENIOR DEBT.

         Upon the payment in full of all Senior Debt, the rights of the holders
of Securities of any series shall be subrogated to all the rights of any holders
of Senior Debt to receive any further payments or distributions applicable to
the Senior Debt until the Securities of any series shall have been paid in full,
and such payments or distributions received by the Holders of Securities of any
series by reason of such subrogation, of cash, securities or other property
which otherwise would be paid or distributed to the holders of Senior Debt,
shall, as between the Corporation and its creditors other than the holders of
Senior Debt, on the one hand, and the Holders of Securities of any series, on
the other, be deemed to be a payment by the Corporation on account of Senior
Debt, and not on account of the Securities of any series.

SECTION 1406. PROVISIONS SOLELY TO DEFINE RELATIVE RIGHTS.

         The provisions of this Article are and are intended solely for the
purpose of defining the relative rights of the Holders of Securities of any
series on the one hand and the holders of Senior Debt on the other hand. Nothing
contained in this article or elsewhere in the Indenture or in the Securities of
such series is intended to or shall

              (a)       impair, as among the Corporation, its creditors other
                        than holders of Senior Debt and the Holders of
                        Securities of such series, the obligation of the
                        Corporation, which is absolute and unconditional (and
                        which, subject to the rights under this Article of the
                        holders of Senior Debt, is intended to rank equally
                        with all other general obligations of the Corporation),
                        to pay to the Holders of Securities of such series the
                        principal of (and premium,

                                       64
<PAGE>
                        if any) and interest on, the Securities of such series
                        as and when the same shall become due and payable in
                        accordance with their terms; or

              (b)       affect the relative rights against the Corporation of
                        the Holders of Securities of such series and creditors
                        of the Corporation, as the case may be, other than the
                        holders of Senior Debt; or

              (c)       prevent the Trustee or the Holder of any Securities of
                        such series from exercising all remedies otherwise
                        permitted by applicable law upon default under this
                        Indenture, subject to the rights, if any, under this
                        Article of the holders of Senior Debt to receive cash,
                        property and securities otherwise payable or
                        deliverable to the Trustee or such Holder.

SECTION 1407. TRUSTEE TO EFFECTUATE SUBORDINATION.

         Each Holder of Securities of any series by such Holder's acceptance
thereof authorizes and directs the Trustee on such Holder's behalf to take such
action as may be necessary or appropriate to effectuate the subordination
provided in this Article and appoints the Trustee his attorney-in-fact for any
and all such purposes.

SECTION 1408. NO WAIVER OF SUBORDINATION PROVISIONS.

         No right of any present or future holder of any Senior Debt to enforce
subordination as herein provided shall at any time in any way be prejudiced or
impaired by any act or failure to act on the part of the Corporation or by any
act or failure to act, in good faith, by any such holder, or by any
noncompliance by the Corporation with the terms, provisions and covenants of
this Indenture, regardless of any knowledge thereof any such holder may have or
be otherwise charged with.

         Without in any way limiting the generality of the foregoing paragraph,
the holders of Senior Debt may, at any time and from time to time, without the
consent of or notice to the Trustee or the Holders of the Securities of any
series, without incurring responsibility to the Holders of the Securities of
such series and without impairing or releasing the subordination provided in
this Article or the obligations hereunder of the Holders of Securities of such
series to the holders of Senior Debt, do any one or more of the following:

              (a)       change the manner, place or terms of payment or extend
                        the time of payment of, or renew or alter, Senior Debt,
                        or otherwise amend or supplement in any manner Senior
                        Debt or any instrument evidencing the same or any
                        agreement under which Senior Debt is outstanding;

              (b)       sell, exchange, release or otherwise deal with any
                        property pledged, mortgaged or otherwise securing
                        Senior Debt;

              (c)       release any Person liable in any manner for the
                        collection of Senior Debt; and

                                       65
<PAGE>
              (d)       exercise or refrain from exercising any rights against
                        the Corporation and any other Person.

SECTION 1409. NOTICE TO TRUSTEE.

         The Corporation shall give prompt written notice to the Trustee of any
fact known to the Corporation which would prohibit the making of any payment to
or by the Trustee in respect of the Securities of any series pursuant to the
provisions of this Article. Notwithstanding the provisions of this Article or
any other provision of the Indenture, the Trustee shall not be charged with
knowledge of the existence of any facts which would prohibit the making of any
payment to or by the Trustee in respect of any Securities of any series
pursuant to the provisions of this Article, unless and until the Trustee shall
have received written notice thereof from the Corporation or a holder or
holders of Senior Debt or from any trustee therefor; and, prior to the receipt
of any such written notice, the Trustee, subject to the provisions of Section
603, shall be entitled in all respects to assume that no such facts exist;
provided, however, that if the Trustee shall not have received the notice
provided for in this Section at least two Business Days prior to the date upon
which by the terms hereof any money may become payable for any purpose
(including, without limitation, the payment of the principal of (or premium, if
any) or interest on any Securities of any series), then, anything herein
contained to the contrary notwithstanding, the Trustee shall have full power and
authority to receive such moneys and to apply the same to the purpose for which
they were received and shall not be affected by any notice to the contrary that
may be received by it within two Business Days prior to such date.

         Subject to the provisions of Section 603, the Trustee shall be
entitled to rely on the delivery to it of a written notice by a Person
representing himself to be a holder of Senior Debt (or a trustee therefor) to
establish that such notice has been given by a holder of Senior Debt (or a
trustee therefor). In the event that the Trustee determines in good faith that
further evidence is required with respect to the right of any Person as a
holder of Senior Debt to participate in any payment of distribution pursuant to
this Article, the Trustee may request such Person to furnish evidence to the
reasonable satisfaction of the Trustee as to the amount of Senior Debt held by
such Person, the extent to which such Person is entitled to participate in such
payment or distribution and any other facts pertinent to the rights of such
Person under this Article, and if such evidence is not furnished, the Trustee
may defer any payment to such Person pending judicial determination as to the
right of such Person to receive such payment.

SECTION 1410. RELIANCE ON JUDICIAL ORDER OR CERTIFICATE OF LIQUIDATING AGENT.

         Upon any payment or distribution of assets of the Corporation referred
to in this Article, the Trustee, subject to the provisions of Section 603, and
the Holders of Securities of any series shall be entitled to conclusively rely
upon any order or decree entered by any court of competent jurisdiction in which
such insolvency, bankruptcy, receivership, liquidation, reorganization,
dissolution winding up or

                                       66
<PAGE>
similar case or proceeding is pending, or a certificate of the trustee in
bankruptcy, receiver, liquidating trustee, custodian, assignee for the benefit
of creditors, agent or other Person making such payment or distribution,
delivered to the Trustee or to the Holders of Securities of such series, for
the purpose of ascertaining the Persons entitled to participate in such payment
or distribution, the holders of the Senior Debt and other indebtedness of the
Corporation, as the case may be, the amount thereof or payable thereon, the
amount or amounts paid or distributed thereon and all other facts pertinent
thereto or to this Article.

SECTION 1411. TRUSTEE NOT FIDUCIARY FOR HOLDERS OF SENIOR DEBT.

         With respect to the holders of Senior Debt, the Trustee undertakes to
perform or to observe only such of its covenants and obligations as are
specifically set forth in this Article, and no implied covenants or obligations
with respect to the holders of such Senior Debt shall be read into this
Indenture against the Trustee. The Trustee shall not be deemed to owe any
fiduciary duty to the holders of Senior Debt with respect to its obligations and
duties created hereunder and shall not be liable to any such holders or
creditors if it shall in good faith pay over or distribute to Holders of
Securities of any series or to the Corporation or to any other Person cash,
property or securities to which any holders of Senior Debt shall be entitled by
virtue of this Article or otherwise.

SECTION 1412. RIGHTS OF TRUSTEE AS HOLDER OF SENIOR DEBT; PRESERVATION OF
TRUSTEE'S RIGHTS.

         The Trustee in its individual capacity shall be entitled to all the
rights set forth in this Article with respect to any Senior Debt which may at
any time be held by it, to the same extent as any other holder of Senior Debt,
and nothing in the Indenture shall deprive the Trustee of any of its rights as
such holder.

         Nothing in this Article shall apply to claims of, or payments to, the
Trustee under or pursuant to Section 607.

SECTION 1413. ARTICLE APPLICABLE TO PAYING AGENTS.

         In case at any time any Paying Agent other than the Trustee shall have
been appointed by the Corporation and be then acting hereunder, the term
"Trustee" as used in this Article shall in such case (unless the context
otherwise requires) be construed as extending to and including such Paying
Agent within its meaning as fully for all intents and purposes as if such
Paying Agent were named in this Article in addition to or in place of the
Trustee; provided, however, that this Section shall not apply to the
Corporation or any Affiliate of the Corporation if it or such Affiliate acts as
Paying Agent.

SECTION 1414. CERTAIN CONVERSIONS OR EXCHANGES DEEMED PAYMENT.

         For the purposes of this Article only, (a) the issuance and delivery of
securities which are subordinate in right of payment to all then outstanding
Senior Debt to substantially the same extent as the Securities are so
subordinate ("Junior Securities") (or cash paid in

                                       67

lieu of fractional shares) upon conversion or exchange of Securities of any
series as contemplated by Section 301, shall not be deemed to constitute a
payment or distribution on account of the principal of or premium or interest on
Securities of such series or on account of the purchase or other acquisition of
Securities of such series and (b) the payment, issuance or delivery of cash,
property or securities (other than Junior Securities and cash paid in lieu of
fractional shares) upon conversion or exchange of Securities of any series shall
be deemed to constitute payment on account of the principal of such Securities
of such series. Nothing contained in this Article or elsewhere in the Indenture
or in the Securities of any series is intended to or shall impair, as among the
Corporation, its creditors other than holders of Senior Debt and the Holders of
Securities of such series the right, which is absolute and unconditional, of the
Holder of any Securities of such series to convert or exchange such Securities
of such series in accordance with the terms specified as contemplated by Section
301.

SECTION 1415. DEFEASANCE OF THIS ARTICLE FOURTEEN.

         The subordination of the Securities provided by this Article Fourteen
is expressly made subject to the provisions for defeasance or covenant
defeasance in Article Thirteen hereof and, anything herein to the contrary
notwithstanding, upon the effectiveness of any such defeasance or covenant
defeasance, the Securities than outstanding shall thereupon cease to be
subordinated pursuant to this Article Fourteen.

      IN WITNESS WHEREOF, the parties hereto have caused this Indenture to be
duly executed, and their respective corporate seals to be hereunto affixed and
attested, all as of the day and year first above written.
