or other action provided by this Indenture to be given or taken by Holders may
be embodied in and evidenced by one or more instruments of substantially similar
tenor signed by such Holders (including Persons who hold their Securities
through a Holder which is a Depositary) 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 hereby expressly required, to the Company. Such
instrument or instruments (and the action embodied therein and evidenced
thereby) are herein sometimes referred to as the "Act" of the Holders signing
such instrument or instruments. Proof of

                                       8

<PAGE>

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 801)
conclusive in favor of the Trustee and the Company, if made in the manner
provided in this Section.

     Without limiting the generality of the foregoing, a Holder, including a
Depositary that is a Holder of a Global Security, may make, give or take, by a
proxy or proxies duly appointed in writing, any request, demand, authorization,
direction, notice, consent, waiver or other action provided or permitted by this
Indenture to be made, given or taken by the Holders, and a Depositary that is a
Holder of a Global Security may provide its proxy or proxies to the beneficial
owners of interest in any such Global Security.

     (b)  The fact and date of the execution by any Person of any such
instrument or writing may be proved in any reasonable manner provided that, in
any instance, the Trustee may require further proof with respect to any matter
referred to in this Section.

     (c)  The ownership of Securities shall be proved by the Security Register.

     (d)  The Company may fix any day as the record date for the purpose of
determining the Holders (including Persons who hold Securities through a Holder
which is a Depositary) of Securities of any series entitled to give or take any
request, demand, authorization, direction, notice, consent, waiver or other
action, or to vote on any action, authorized or permitted to be given or taken
by Holders of Securities of such series. If not set by the Company prior to the
first solicitation of a Holder of Securities of such series made by any Person
in respect of any such action, or, in the case of any such vote, prior to such
vote, the record date for any such action or vote shall be the 30th day (or, if
later, the date of the most recent list of Holders required to be provided
pursuant to TIA Section 312) prior to such first solicitation or vote, as the
case may be. With regard to any record date for action to be taken by the
Holders (including Persons who hold Securities through a Holder which is a
Depositary) of one or more series of Securities, only the Holders of Securities
of such series on such date (or their duly designated proxies) shall be entitled
to give or take, or vote on, the relevant action.

     With regard to any action that may be given or taken hereunder only by
Holders (including Persons who hold their Securities through a Holder which is a
Depositary) of a requisite principal amount of Outstanding Securities of any
series (or their duly appointed agents) and for which a record date is set
pursuant to this subsection (d), the Company may, at its option, set an
expiration date after which no such action purported to be given or taken by any
Holder shall be effective hereunder unless given or taken on or prior to such
expiration date by Holders (including Persons who hold Securities through a
Holder which is a Depositary) of the requisite principal amount of Outstanding
Securities of such series on such record date (or their duly appointed agents).
On or prior to any expiration date set pursuant to this subsection (d), the
Company may, on one or more occasions at its option, extend such date to any
later date. Nothing in this subsection (d) shall prevent any Holder (or any duly
appointed agent thereof) from giving or taking, after any expiration date, any
action identical to, or, at any time, contrary to or different from any action
given or taken, or purported to have been given and taken, hereunder by a Holder
on or prior to such date, in which event the Company may set a record date in
respect hereof pursuant to this subsection (d).

     Notwithstanding the foregoing, upon actual receipt by a Responsible Officer
of the Trustee, with respect to Securities of any series, of (i) any Notice of
Default pursuant to Section 701, (ii) any declaration or acceleration, or any
rescission and annulment of any such declaration, pursuant to Section 702, or
(iii) any waiver given pursuant to Section 704 (any such notice, declaration,
rescission and annulment, or waiver being referred to herein as a "Direction"),
a record date shall automatically and without any other action by any Person be
set for the purpose of determining the Holders (including Persons who hold
Securities through a Holder which is a Depositary) of Outstanding Securities of
such series entitled to join in such Direction, which record date shall be the
close of business on the day the Trustee receives such Direction. The Holders
(including Persons who hold Securities through a Holder which is a Depositary)
of Outstanding Securities of such series on such record date (or their duly
appointed agents), and only such Persons, shall be entitled to join in such
Direction, whether or not such Holders remain Holders after such record date;
provided that, unless such Direction shall have become effective by virtue of
Holders (including Persons who hold Securities through a Holder which is a
Depositary) of the requisite principal amount of Outstanding Securities of such
series on such record date (or their duly appointed agents) having joined
therein on or prior to the 90th day after such record date, such Direction shall
automatically and without any action by any Person be canceled and be of no
further effect. Nothing in this paragraph shall prevent a Holder (or duly
appointed agent thereof) from giving, before or after the expiration of such
90-day period, a Direction contrary to or different from, or, after the
expiration of such period, identical to, a Direction that has been canceled
pursuant to the proviso to the preceding sentence, in which event a new record
date in respect thereof shall be set pursuant to this subsection (d).

     (e)  Any request, demand, authorization, direction, notice, consent, waiver
or other Act of the Holder of any Security shall bind every future Holder of the
same Security and the Holder of every Security issued upon the registration of
transfer thereof or in exchange therefor or in lieu thereof in respect of

reliance thereon, whether or not notation of such action is made upon such

Section 107.   Notices, Etc., to Trustee and Company>>.
               ---------------------------------------

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

               (1)  the Trustee by any Holder or by the Company shall be
          sufficient for every purpose hereunder (unless otherwise herein
          expressly provided) if in writing and mailed, postage prepaid and
          return receipt requested, or sent by overnight courier to a
          Responsible Officer of the Trustee at its Corporate Trust Office,
          Attention: Corporate Trust Administration, or

               (2)  the Company by the Trustee or by any Holder shall be
          sufficient for every purpose hereunder (unless otherwise herein
          expressly provided) if in writing and mailed, postage prepaid and
          return receipt requested, or sent by overnight courier to the Company
          addressed to it at the address of its principal office specified in
          the first paragraph of this instrument (Attention: General

                                       10

          Counsel) or at any other address previously furnished in writing to a
          Responsible Officer of the Trustee by the Company.

Section 108.   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 (including
Persons who hold Securities through a Holder which is a Depositary if the name
and address of such beneficial holder has been provided in writing to the Person
required to give such notice prior to the date such notice is given) affected by
such event, at such Holder's address as it appears in the Security Register or
as provided in writing by the Depositary, not later than the latest date, and
not earlier than the earliest date, 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. Any
notice mailed to the Holder in the manner herein prescribed shall be
conclusively deemed to have been received by such Holder, whether or not such
Holder actually receives such notice. Where this Indenture provides for notice
in any manner, such notice may be waived in writing by the Person entitled to
receive such notice, either before or after the event, and such waiver shall be
the equivalent of such notice. Waivers of notice by Holders shall be filed with
a Responsible Officer of 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 by or with the approval of the Trustee shall
constitute a sufficient notification for every purpose hereunder.

Section 109.   Communication by Holders with Other Holders>>.
               ---------------------------------------------

     Holders may communicate pursuant to TIA Section 312(b) with other Holders

          Securities of the series pursuant to Section 304, 305, 306, 1007 and
          1205 and except for any Securities which, pursuant to Section 303, are
          deemed never to have been authenticated and delivered hereunder) and
          the absence of such limitation shall mean that the Company may issue
          from time to time additional securities of such series without
          limitation as to aggregate principal amount;

               (3)  the Person to whom any interest on a Security of the series

          series shall be payable, any Securities of the series may be
          surrendered for registration of transfer or exchange and notices and

          forth in Section 305;

               (17) if applicable, that the Securities of the series, in whole
          or any specified part, shall not be defeasible pursuant to Section 902
          or Section 903 or both such Sections and, if other than by a Company

     All Securities of any one series (other than Securities offered in a

and except as may otherwise be provided by or pursuant to the Board Resolution
referred to above and, subject to Section 303, set forth, or determined in the
manner provided, in the Officers' Certificate referred to above or in any such
indenture supplemental hereto. All Securities of any one series need not be
issued at the same time. Unless otherwise provided, Securities of a single
series may have different terms, and a series may be reopened, without the
consent of the Holders of Securities of such series, for issuance of additional
Securities of such series.

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

     With respect to Securities of a series offered in a Periodic Offering, such
Board Resolution and Officers' Certificate or supplemental indenture may provide
general terms or parameters for Securities of such series and provide either
that the specific terms of particular Securities of such series shall be
specified in a Company Order or that such terms shall be determined by the
Company or its agents in accordance with other procedures specified in a Company
Order as contemplated by the third paragraph of Section 303.

Section 302.   Denominations>>.
               ---------------

     Unless otherwise provided in the applicable Officers' Certificate or
supplemental indenture, the Securities of each series shall be issued in
registered form without coupons in such

                                       15

<PAGE>

denominations as shall be specified as contemplated by Section 301. In the
absence of any such provisions with respect to the Securities of any series, the
Securities of such series shall be issuable in denominations of $1,000 or any
amount in excess thereof which is an integral multiple of $1,000.

Section 303.   Execution, Authentication, Delivery and Dating>>.
               ------------------------------------------------

     The Securities shall be executed on behalf of the Company by its Chairman
of the Board, its President, its Chief Executive Officer, its Chief Operating
Officer, its Chief Financial Officer or one of its Vice Presidents, and attested
by its Secretary or one of its Assistant Secretaries. The signature of any of
these officers on the Securities may be manual or facsimile.

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

     At any time and from time to time after the execution and delivery of this
Indenture, the Company may deliver Securities of any series executed by the
Company to the Trustee for authentication, together with a Company Order for the
authentication and delivery of such Securities, or, in the case of Securities
offered in a Periodic Offering, from time to time in accordance with such other
procedures (including, without limitation, the actual receipt by the Trustee of
electronic instructions from the Company or its duly authorized agents, promptly
confirmed in writing by the Company) acceptable to the Trustee as may be
specified from time to time by a Company Order for establishing the specific
terms of particular Securities being so offered, and the Trustee in accordance
with the Company Order shall authenticate and deliver such Securities. If the
form or forms or terms of the Securities of the series have been established by
or pursuant to one or more Board Resolutions 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 801) shall be
fully protected in conclusively relying upon

     (a)  an Opinion of Counsel stating:

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

               (2)  that the terms of such Securities have been established in
          conformity with the provisions of this Indenture;

               (3)  that authentication and delivery of such Securities and the
          execution and delivery of the supplemental indenture, if any, by the
          Trustee will not violate the terms of the Indenture;

               (4)  that the Company has the corporate power to issue, and has
          duly authorized, such Securities; and

                                       16

<PAGE>

               (5)  that such Securities, when authenticated and delivered by a
          Responsible Officer of the Trustee and issued by the Company in the
          manner and subject to any conditions specified in such Opinion of
          Counsel, will constitute valid and legally binding obligations of the
          Company, enforceable against the Company in accordance with their
          terms, subject to bankruptcy, insolvency, reorganization, moratorium,
          fraudulent conveyance or transfer and other laws of general
          applicability relating to or affecting the enforcement of creditors'
          rights and to general equity principles;

     (b)  an executed supplemental indenture, if any;

     (c)  a copy of a Board Resolution; and

     (d)  an Officers' Certificate;

provided, however, that, with respect to Securities of a series offered in a
Periodic Offering, the Trustee shall be entitled to receive such Opinion of
Counsel in connection only with the first authentication of each form of
Securities of such series and that the opinions described in clauses (a)(2) and
(a)(5) above may state, respectively, that

          (2)  if the terms of such Securities are to be established pursuant to
     a Company Order or pursuant to such procedures as may be specified from
     time to time by a Company Order, all as contemplated by a Board Resolution
     or action taken pursuant thereto, such terms will have been duly authorized
     by the Company and established in conformity with the provisions of this
     Indenture; and

          (5)  that such Securities, when executed by the Company, completed,
     authenticated and delivered by the Trustee in accordance with this
     Indenture, and issued and delivered by the Company and paid for, all in
     accordance with any agreement of the Company relating to the offering,
     issuance and sale of such Securities, will be duly issued under this
     Indenture and will constitute valid and legally binding obligations of the
     Company, enforceable against the Company in accordance with their terms,
     subject to bankruptcy, insolvency, reorganization, moratorium, fraudulent
     conveyance or transfer and other laws of general applicability relating to
     or affecting the enforcement of creditors' rights and to general equity
     principles.

     With respect to Securities of a series offered in a Periodic Offering, the
Trustee may conclusively rely, as to the authorization by the Company of any of
such Securities, the form or forms and terms thereof and the legality, validity,
binding effect and enforceability thereof, upon the Opinion of Counsel, Company
Order and other documents delivered pursuant to Sections 201 and 301 and this
Section, as applicable, in connection with the first authentication of a form of
Securities of such series and it shall not be necessary for the Company to
deliver such Opinion of Counsel and other documents (except as may be required
by the specified other procedures, if any, referred to above) at or prior to the
time of authentication of each Security of such series unless and until a
Responsible Officer of the Trustee receives notice that such Opinion of Counsel
or other documents have been superseded or revoked, and may assume compliance
with any conditions specified in such Opinion of Counsel (other than any
conditions to be performed

                                       17

<PAGE>

by the Trustee). If such form or forms 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.

     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 a Responsible Officer of the Trustee by manual signature, and such
certificate upon any Security shall be conclusive evidence, and the only
evidence, that such Security has been duly authenticated and delivered hereunder
and is entitled to the benefits of this Indenture. Notwithstanding the
foregoing, if any Security shall have been authenticated and delivered hereunder
but never issued and sold by the Company, and the Company shall deliver such
Security to the Trustee for cancellation as provided in Section 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 Company
may execute, and upon Company Order a Responsible Officer of the Trustee shall
authenticate and deliver, temporary Securities which are printed, lithographed,
typewritten 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. In the case of Securities of any series, such
temporary Securities may be in the form of Global Securities.

     If temporary Securities of any series are issued, the Company will cause
definitive Securities of that series to be prepared without unreasonable delay.
After the preparation of definitive Securities of such series, the temporary
Securities of such series shall be exchangeable, subject to Section 305, for
definitive Securities of like tenor of such series upon surrender of the
temporary Securities of such series at the office or agency of the Company in a
Place of Payment for that series, without charge to the Holder. Upon surrender
for cancellation of any one or more temporary Securities of any series the
Company shall execute and a Responsible Officer of the Trustee shall
authenticate and deliver in exchange therefor a like principal amount of
definitive Securities of the same series and of like tenor and of any authorized
denominations. 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 Company shall cause to be kept at the Corporate Trust Office of the
Trustee a register (the "Security Register") in which, subject to such
reasonable regulations as it may prescribe, the Company shall provide for the
registration of Securities and of transfers of Securities. The Trustee is hereby
appointed "Security Registrar" of each series of Securities for

                                       18

<PAGE>

the purpose of registering Securities and transfers of Securities as herein
provided at the Corporate Trust Office.

     Upon surrender for registration of transfer of any Security of any series
at the office or agency of the Company in any Place of Payment for such series,
the Company shall execute and a Responsible Officer of 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 a like aggregate principal amount and tenor and bearing a
number not contemporaneously outstanding.

     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 a
like aggregate principal amount and tenor, upon surrender of the Securities to
be exchanged at the office or agency of the Company in any Place of Payment for
such series. Whenever any Securities are so surrendered for exchange, the
Company shall execute, and a Responsible Officer of the Trustee shall
authenticate and deliver, the Securities which the Holder making the exchange is
entitled to receive.

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

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

     No service charge shall be made for any registration of transfer or
exchange of Securities, but the Company may require payment of a sum sufficient
to cover any tax or other governmental charge that may be imposed in connection
with any registration of transfer or exchange of Securities, other than
exchanges pursuant to Section 304, 1007 or 1205 not involving any transfer.

     The Company may but shall not be required (i) to issue, register the
transfer of or exchange Securities of any series during a period beginning at
the opening of business 15 days before the day of the mailing of a notice of
redemption of Securities of that series selected for redemption under Section
403 and ending at the close of business on the day of such mailing, (ii) 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 or (iii) to register the transfer of or exchange any certificated
Securities during a period beginning five days before the date of Maturity with
respect to such Security and ending on such date of Maturity.

     Notwithstanding the foregoing, except as otherwise specified as
contemplated by Section 301, no Global Security shall be exchangeable pursuant
to this Section 305 for Securities registered in the name of, and no transfer of
a Global Security of any series may be registered to, any Person other than the
Depositary for such Security or its nominee, unless (i) such Depositary notifies
the Company that it is unwilling or unable to continue as Depositary for such
Global

                                       19

<PAGE>

Security or the Company determines that the Depositary is unable to
continue as Depositary and the Company thereafter fails to appoint a successor
Depositary, (ii) the Company provides for such exchange or registration of
transfer pursuant to Section 301 of this Indenture, (iii) the Company executes
and delivers to the Trustee a Company Order that such Global Security shall be
so exchangeable and the transfer thereof so registrable, or (iv) there shall
have occurred and be continuing an Event of Default with respect to the
Securities of such series which entitles the Holders of such Securities to
accelerate the maturity thereof. Upon the occurrence in respect of any Global
Security of any series of any one or more of the conditions specified in clauses
(i), (ii), (iii) or (iv) of the preceding sentence or such other conditions as
may be specified as contemplated by Section 301 for such series, such Global
Security may be exchanged for Securities not bearing the legend specified in
Section 203 and registered in the names of such Persons as may be specified by
the Depositary (including Persons other than the Depositary or its nominees).

     Notwithstanding any other provision of this Indenture, a Global Security
may not be transferred except as a whole by the Depositary for such Global
Security to a nominee of the Depositary or by a nominee of the Depositary to the
Depositary or another nominee of the Depositary.

Section 306.   Mutilated, Destroyed, Lost and Stolen Securities>>.
               --------------------------------------------------

     If any mutilated Security, including a Global Security, is surrendered to
the Trustee or the Company, together with such security, bond or indemnity as
may be required by the Trustee or the Company to save each of them and any agent
of either of them harmless, the Company shall execute and the Trustee shall
authenticate and deliver in exchange therefor a new Security, including a new
Global Security if the mutilated Security was a Global 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 Company and the Trustee (i) evidence to
their satisfaction of the destruction, loss or theft of any Security, including
a Global Security if the destroyed, lost or stolen Security was a Global
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 Company or the Trustee that such Security has been acquired by a
bona fide purchaser, the Company shall execute and upon its written request the
Trustee shall authenticate and deliver, in lieu of any such destroyed, lost or
stolen Security, a new Security, including a Global Security if the destroyed,
lost or stolen Security was a Global 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 Company in its discretion may,
instead of issuing a new Security, pay such Security.

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

                                       20

<PAGE>

in relation thereto and any other expenses (including the fees and expenses of
the Trustee), if any, 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 Company, 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. A new
Security shall have such legends as appeared on the old Security unless the
Company determines otherwise.

     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>>.
               ------------------------------------------------

     Unless 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 in the Security Register at the close of business on
the Regular Record Date for such Interest Payment Date.

     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 Company, at its election in each case, as
provided in clause (1) or (2) below:

               (1)  The Company may elect to make payment of any Defaulted
          Interest to the Persons in whose names the Securities of such series
          (or their respective Predecessor Securities) are registered at the
          close of business on a Special Record Date for the payment of such
          Defaulted Interest, which shall be fixed in the following manner. The
          Company shall notify the Trustee in writing of the amount of Defaulted
          Interest proposed to be paid on each Security of such series and the
          date of the proposed payment, and at the same time the Company shall
          deposit with the Trustee an amount of money equal to the aggregate
          amount proposed to be paid in respect of such Defaulted Interest or
          shall make arrangements satisfactory to the Trustee for such deposit
          prior to the date of the proposed payment, such money when deposited
          to be held in trust for the benefit of the Persons entitled to such
          Defaulted Interest as in this clause provided. Thereupon the Trustee
          shall fix a Special Record Date for the payment of such Defaulted
          Interest which shall be not more than 15 days and not less than 5 days
          prior to the date of the proposed payment and not less than 10 days
          after the receipt by the Trustee of the notice of the proposed
          payment. The Trustee shall promptly notify the Company of such Special
          Record Date and, in the name and at the expense of the Company, shall
          cause notice of the proposed payment of such Defaulted Interest and
          the Special Record Date therefor to be mailed, first-

                                       21

<PAGE>

          class postage prepaid, to each Holder of Securities of such series at
          such Holder's address as it appears in the Security Register, not less
          than 15 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 Company 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 Company to the Trustee
          of the proposed payment pursuant to this clause, such manner of
          payment shall be deemed practicable by the Trustee.

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

Section 308.   Persons Deemed Owners>>.
               -----------------------

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

     No holder of any beneficial interest in any Global Security held on its
behalf by a Depositary (or its nominees) shall have any rights under this
Indenture with respect to such Global security or any Security represented
thereby, and such Depositary may be treated by the Company, the Trustee, and any
agent of the Company or the Trustee as the owner of such Global Security or any
Security represented thereby for all purposes whatsoever. Notwithstanding the
foregoing, with respect to any Global Security, nothing herein shall prevent the
Company, the Trustee, or any agent of the Company or the Trustee, from giving
effect to any written certification, proxy or other authorization furnished by a
Depositary as Holder of such Global Security, or impair, as between a Depositary
and the owners of beneficial interests in such Global Security, the operation of
customary practices governing the exercise of the rights of the Depositary (or
its nominees) as Holder of such Global Security.

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

                                       22

<PAGE>

Trustee, be delivered to the Trustee and shall be promptly canceled by it. The
Company may at any time deliver to the Trustee for cancellation any Securities
previously authenticated and delivered hereunder which the Company may have
acquired in any manner whatsoever, and may deliver to the Trustee (or to any
other Person for delivery to the Trustee) for cancellation any Securities
previously authenticated hereunder which the Company has not issued and sold,
and all Securities so delivered shall be promptly canceled by the Trustee. No
Securities shall be authenticated in lieu of or in exchange for any Securities
canceled as provided in this Section, except as expressly permitted by this
Indenture. The Trustee is hereby directed by the Company to cancel the
Securities held by the Trustee (subject to the record retention requirements of
the Exchange Act), and the Trustee shall return such cancelled Securities to the
Company.

Section 310.   Computation of Interest>>.
               -------------------------

     Except as otherwise specified pursuant to 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 and no interest will accrue with
respect to the 31st day of any month.

Section 311.   CUSIP Number>>.
               --------------

     The Company in issuing the Securities may use "CUSIP" numbers, and if it
does so, the Trustee shall use the applicable CUSIP number in notices of
redemption or exchange as a convenience to Holders; provided that any such
notice may state that no representation is made as to the correctness or
accuracy of the CUSIP number printed in the notice or on the Securities, and
that reliance may be placed only on the other identification numbers printed on
the Securities. The Company will promptly notify the Trustee of any change in
any CUSIP number.

                                  ARTICLE IV.
                            REDEMPTION OF SECURITIES

Section 401.   Applicability of Article>>.
               --------------------------

     Unless otherwise specifically provided for in accordance with Section 301
with respect to any series of Securities, the Company shall have no mandatory
redemption or sinking fund obligations with respect to the Securities of any
series. Securities of any series which are redeemable before their Stated
Maturity in accordance with their terms as specifically established in
accordance with Section 301 shall be redeemable in accordance with their terms
and, except as otherwise provided by such terms, in accordance with this
Article.

Section 402.   Notices to Trustee>>.
               --------------------

     If the Company elects to redeem any Securities pursuant to any optional
redemption provisions established with respect to such series hereof, it shall
furnish to the Trustee, at least 40 days but not more than 60 days before the
Redemption Date, an Officers' Certificate setting forth (i) such Redemption
Date, (ii) the Redemption Price, (iii) if the Securities of such series have
different terms and less than all of the Securities of such series are to be
redeemed, the terms of the Securities to be redeemed and (iv) if less than all
the Securities of such series with identical terms are to be redeemed, the
principal amount of such Securities to be redeemed.

                                       23

<PAGE>

     In the case of any redemption of Securities prior to the expiration of any
restriction on such redemption provided in the terms of such Securities or
elsewhere in this Indenture, the Company shall furnish the Trustee with an
Officers' Certificate evidencing compliance with such restriction.

Section 403.   Selection of Securities to Be Redeemed>>.
               ----------------------------------------

     If less than all of the Securities of like tenor of any series are to be
redeemed at any time, the Trustee shall select the particular Securities to be
redeemed among the Holders on a pro rata basis (and in such manner as complies
with applicable legal and stock exchange requirements, if any) or in such other
manner as the Trustee, in the exercise of its reasonable discretion, deems fair
and appropriate. In the event of partial redemption by lot, the particular
Securities to be redeemed from the Outstanding Securities of like tenor of such
series shall be selected, unless otherwise provided herein, not less than 30 nor
more than 60 days prior to the Redemption Date by the Trustee from the
Outstanding Securities of like tenor of such series not previously called for
redemption.

     The Trustee shall promptly notify the Company in writing of the Securities
selected for redemption and, in the case of any Security selected for partial
redemption, the principal amount thereof to be redeemed. Securities and portions
of them selected shall be in amounts of $1,000 or whole multiples of $1,000;
except that if all of the Securities of a Holder are to be redeemed, the entire
outstanding amount of Securities held by such Holder, even if not a multiple of
$1,000, shall be redeemed. Except as provided in the preceding sentence,
provisions of this Indenture that apply to Securities called for redemption also
apply to portions of Securities called for redemption.

Section 404.   Notice of Redemption>>.
               ----------------------

     At least 30 days but not more than 60 days before a Redemption Date, notice
of redemption shall be delivered by first-class mail, postage prepaid, to each
Holder whose Securities are to be redeemed at each such Holder's address
appearing in the Security Register.

     The notice shall identify the Securities to be redeemed and shall state:

               (1)  the Redemption Date;

               (2)  the Redemption Price;

               (3)  if less than all the Outstanding Securities of like tenor of
          any series are to be redeemed, the portion of the principal amount of
          any Security of such series to be redeemed and that, after the
          redemption date upon surrender of such Security, a new Security or
          Securities in principal amount equal to the unredeemed portion shall
          be issued;

               (4)  the place or places where such Securities are to be
          surrendered for payment of the Redemption Price;

                                       24

<PAGE>

               (5)  that, unless the Company defaults in making such redemption
          payment, interest on Securities called for redemption ceases to accrue
          on and after the Redemption Date;

               (6)  the paragraph of the Securities and/or Section of this
          Indenture pursuant to which the Securities called for redemption are
          being redeemed; and

               (7)  that no representation is made as to the correctness or
          accuracy of the CUSIP number, if any, listed in such notice or printed
          on the Securities.

     At the Company's request, the Trustee shall give the notice of redemption
in the Company's name and at its expense; provided, however, that the Company
shall have delivered to the Trustee, at least 40 days prior to the redemption
date, an Officers' Certificate requesting that the Trustee give such notice and
setting forth the information to be stated in such notice as provided in the
preceding paragraph. The notice mailed in the manner herein provided shall be
conclusively presumed to have been duly given whether or not the Holder receives
such notice. In any case, failure to give such notice by mail or any defect in
the notice to the Holder of any Security shall not affect the validity of the
proceeding for the redemption of any other Security.

Section 405.   Effect of Notice of Redemption>>.
               --------------------------------

     Once notice of redemption is mailed in accordance with Section 404 hereof,
Securities called for redemption become due and payable on the redemption date
at the redemption price plus accrued and unpaid interest, if any, to such date.

Section 406.   Deposit of Redemption Price>>.
               -----------------------------

     At or before 10:00 a.m. Eastern Time on the Redemption Date, the Company
shall deposit with the Trustee or with a Paying Agent (or, if the Company is
acting as its own Paying Agent, segregate and hold in trust as provided in
Section 503) an amount of money, sufficient to pay the redemption price of and
accrued interest on all Securities to be redeemed on that date. The Trustee or
the Paying Agent shall promptly return to the Company any money deposited with
the Trustee or the Paying Agent by the Company in excess of the amounts
necessary to pay the Redemption Price of (including any applicable premium), and
accrued interest on, all Securities to be redeemed.

Section 407.   Securities Payable on Redemption Date>>.
               ---------------------------------------

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

                                       25

<PAGE>

registered as such at the close of business on the relevant Regular 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 for redemption, the principal (and premium, if any) shall, until paid,
bear interest from the Redemption Date at the rate prescribed therefor in the
Security.

Section 408.   Securities Redeemed in Part>>.
               -----------------------------

     Any Security which is to be redeemed in part shall be surrendered at a
Place of Payment for such series (with, if the Company or the Trustee so
requires, due endorsement by, or a written instrument of transfer in form
satisfactory to the Company and the Trustee duly executed by, the Holder thereof
or such Holder's attorney duly authorized in writing), and the Company shall
execute, and the Trustee shall authenticate and deliver to the Holder 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. To the extent a series
of Securities represented by a Global Security is to be redeemed only in part, a
notation of such redemption shall be made by the Trustee in the schedule of
exchanges on the Global Security.

                                   ARTICLE V.
                                   COVENANTS

Section 501.   Payment of Principal, Premium and Interest>>.
               --------------------------------------------

     The Company covenants and agrees for the benefit of each series of
Securities that it will duly and punctually pay the principal of (and premium,
if any) and interest on the Securities of such series in accordance with the
terms of such Securities and this Indenture. Principal of (premium, if any) and
interest on the Securities of any series shall be considered paid on the date
due if the Paying Agent, if other than the Company or a Subsidiary of the
Company, holds as of 10:00 a.m. Eastern Time on the due date money, deposited by
the Company in immediately available funds and designated for and sufficient to
pay all principal, premium, if any, and interest then due. Such Paying Agent
shall return to the Company, no later than one Business Day following the date
of payment, any money (including accrued interest) that exceeds such amount of
principal (premium, if any) and interest paid on the Securities of such series.

     The Company shall, unless otherwise provided for as contemplated by Section
301, pay interest (including post-petition interest in any proceeding under any
Bankruptcy Law) on overdue principal of the Securities of any series at the rate
equal to 1% per annum in excess of the interest rate then applicable to such
series to the extent lawful. In addition, the Company shall pay interest on the
Securities of any series (including post-petition interest in any proceeding
under any Bankruptcy Law) on overdue installments of interest (without regard to
any applicable grace period) at the same rate to the extent lawful.

<PAGE>

Section 502.   Maintenance of Office or Agency>>.
               ---------------------------------

     Unless otherwise provided for as contemplated by Section 301, the Company
shall maintain in the Borough of Manhattan, the City of New York, and in each
Place of Payment for any series of securities, an office or agency (which may be
an office of the Trustee or an affiliate of the Trustee, the Security Registrar
or co-registrar) where Securities of such series may be surrendered for
registration of transfer or exchange and where notices and demands to or upon
the Company in respect of the Securities of such series and this Indenture may
be served. The Company shall give prompt written notice to the Trustee of the
location, and any change in the location, of such office or agency. If at any
time the Company shall fail to maintain such an office or agency or shall fail
to furnish the Trustee with the address thereof, such presentations, surrenders,
notices and demands may be made or served at the Corporate Trust Office of the
Trustee, and the Company hereby appoints the Trustee as its agent to receive all
such presentations, surrenders, notices and demands.

     The Company may also from time to time designate one or more other offices
or agencies where the Securities of one or more series may be presented or
surrendered for any or all such purposes and may from time to time rescind such
designations; provided, however, that no such designation or rescission shall in
any manner relieve the Company of its obligation, unless otherwise provided for
as contemplated by Section 301, to maintain an office or agency in the Borough
of Manhattan, the City of New York and in each Place of Payment for Securities
of any series for such purposes. The Company shall 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 503.   Money for Securities Payments to Be Held in Trust>>.
               ---------------------------------------------------

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

     Whenever the Company shall have one or more Paying Agents for any series of
Securities, it will, prior to each due date of the principal of (and premium, if
any) or interest on any Securities of such series, deposit with a Paying Agent a
sum sufficient to pay the principal (and premium, if any) or interest so
becoming due, such sum to be held in trust for the benefit of the Persons
entitled to such principal, premium or interest, and (unless such Paying Agent
is the Trustee) the Company will promptly notify the Trustee of its failure so
to act.

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

                                       27

as an unsecured general creditor, look only to the Company for payment thereof,
and all liability of the Trustee or such Paying Agent with respect to such trust
money, and all liability of the Company as trustee thereof, shall thereupon
cease; provided, however, that the Trustee or such Paying Agent, before being
required to make any such repayment, may at the expense of the Company cause to
be published once, in a newspaper published in the English language, customarily
published on each Business Day and of general circulation in the Borough of
Manhattan, the City of New York, notice that such money remains unclaimed and
that, after a date specified therein, which shall not be less than 30 days from
the date of such publication, any unclaimed balance of such money then remaining
will be repaid to the Company on Company Request.

                              DEFAULTS AND REMEDIES

Section 701.   Events of Default>>.
               -------------------

     "Event of Default", wherever used herein with respect to Securities of any
series, and unless otherwise provided with respect to Securities of any series
pursuant to Section 301, means any one of the following events (whatever the
reason for such Event of Default and whether it shall be voluntary or
involuntary or be effected by operation of law or pursuant to any judgment,
decree or order of any court or any order, rule or regulation of any
administrative or governmental body):

          (i)   a default for 30 days in the payment when due of interest on any
     Security of such series;

          (ii)  a default in payment when due of principal of or premium, if
     any, on any Security of such series at Maturity, upon redemption or
     otherwise;

          (iii) a failure by the Company to deposit any "mandatory sinking fund
     payment" (as defined in Section 1101 hereof), when and as due, in respect
     of the Securities of such series;

          (iv)  a default in the performance or breach of Article 6;

          (v)   failure by the Company for 60 days after notice to comply with
     any of its other agreements in this Indenture or any Security of such
     series;

          (vi)  the Company or any Subsidiary of the Company pursuant to or
     within the meaning of any Bankruptcy Law:

                (a) commences a voluntary case,

                (b) consents to the entry of an order for relief against it in
          an involuntary case in which it is the debtor,

                (c) consents to the appointment of a Custodian of it or for all
          or substantially all of its property,

                (d) makes a general assignment for the benefit of its creditors,
          or

                (e) admits in writing its inability generally to pay its debts
          as the same become due;

          (vii) a court of competent jurisdiction enters an order or decree
     under any Bankruptcy Law that:

                (a) is for relief against the Company or any Subsidiary of the
          Company in an involuntary case in which it is the debtor,

                                       32

<PAGE>

                (b) appoints a Custodian of the Company or any Subsidiary
          thereof or for all or substantially all of the property of the Company
          or any Subsidiary thereof, or

                (c) orders the liquidation of the Company or any Subsidiary of
          the Company,

                and the order or decree remains unstayed and in effect for 60
          days; and

          (viii) any other Event of Default provided with respect to Securities
     of such series pursuant to Section 301.

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

     A Default under clause (v) is not an Event of Default with respect to any
series of Securities until the Trustee notifies the Company in writing, or the
Holders of at least 25% in principal amount of the then Outstanding Securities
of such series notify the Company and the Trustee in writing, of the Default and
the Company does not cure the Default within 60 days after receipt of such
notice. The written notice must specify the Default, demand that it be remedied
and state that the notice is a "Notice of Default."

     In the case of any Event of Default with respect to the Securities of any
series pursuant to the provisions of this Section 701 occurring by reason of any
willful action (or inaction) taken (or not taken) by or on behalf of the Company
or any of its Subsidiaries the primary purpose of which was to allow the Company
to avoid payment of the premium, if any, that the Company would have had to pay
with respect to the Securities of such series if the Company then had elected to
redeem such Securities pursuant to the optional redemption provisions, if any,
established in accordance with this Indenture with respect to such Securities,
an equivalent premium shall also become and be immediately due and payable if
such Securities are repaid to the extent permitted by law, anything in this
Indenture or in the Securities of such series to the contrary notwithstanding.

Section 702.   Acceleration>>.
               --------------

     If an Event of Default with respect to the Outstanding Securities of any
series (other than an Event of Default specified in clauses (vi) and (vii) of
Section 701) occurs and is continuing, the Trustee by notice to the Company, or
the Holders of not less than 25% in aggregate principal amount of the
Outstanding Securities of such series by written notice to the Company and the
Trustee, may declare the unpaid principal of (or, if any of the Securities of
such series are Original Issue Discount Securities, such lesser portion of the
principal amount of such Securities as may be specified in the terms thereof),
premium, if any, and any accrued and unpaid interest on all the Securities of
that series to be due and payable. Upon such declaration the principal (or
specified portion thereof), premium, if any, and interest shall be due and
payable immediately. If an Event of Default specified in clause (vi) or (vii) of
Section 701 occurs with respect to the Company or any Subsidiary thereof such an
amount shall ipso facto become and be immediately due and payable without any
declaration or other act on the part of the Trustee or any Holder.

                                       33

<PAGE>

The Holders of a majority in principal amount of the Outstanding Securities of
such series by written notice to the Trustee may rescind an acceleration and its
consequences if the rescission would not conflict with any judgment or decree
and if all existing Events of Default with respect to such series (except
nonpayment of principal or interest that has become due solely because of the
acceleration) have been cured or waived.

Section 703.   Other Remedies>>.
               ----------------

     If an Event of Default with respect to the Outstanding Securities of any
series occurs and is continuing, the Trustee may pursue any available remedy
(under this Indenture or otherwise) to collect the payment of principal,
premium, if any, or interest on the Securities of such series or to enforce the
performance of any provision of such Securities or this Indenture.

     The Trustee may maintain a proceeding at the expense of the Company with
respect to the Outstanding Securities of any series even if it does not possess
any of the Securities of such series or does not produce any of them in the
proceeding. A delay or omission by the Trustee or any Holder of such Securities
in exercising any right or remedy accruing upon an Event of Default shall not
impair the right or remedy or constitute a waiver of or acquiescence in the
Event of Default. All remedies are cumulative to the extent permitted by law.

Section 704.   Waiver of Past Defaults>>.
               -------------------------

     Holders of not less than a majority in aggregate principal amount of the
Outstanding Securities of any series by written notice to the Trustee may waive
an existing Default or Event of Default with respect to the Securities of such
series and its consequences, except a continuing Default or Event of Default in
the payment of the principal of, premium, if any, or interest on any Security of
such series held by a nonconsenting Holder (other than a rescission of
acceleration of the Securities of such series by the Holders of at least a
majority in aggregate principal amount of the Securities of such series and a
waiver of the payment default resulting from such acceleration). Upon any such
waiver, such Default shall cease to exist, and any Event of Default with respect
to the Securities of such series 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 705.   Control by Majority>>.
               ---------------------

     Holders of a majority in principal amount of the Outstanding Securities of
any series may direct the time, method and place of conducting any proceeding
for any remedy available to the Trustee with respect to such series or
exercising any trust or power conferred on the Trustee with respect to such
series. However, the Trustee may refuse to follow any direction that conflicts
with law or this Indenture that the Trustee determines may be unduly prejudicial
to the rights of other Holders of Securities of such series or that may involve
the Trustee in personal liability. The Trustee may take any other action which
it deems proper which is not inconsistent with any such direction.

                                       34

<PAGE>

Section 706.   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:

          (i)   the Holder gives to the Trustee written notice of a continuing
     Event of Default with respect to the Securities of such series;

          (ii)  the Holders of at least 25% in principal amount of the
     Outstanding Securities of such series make a written request to the Trustee
     to pursue the remedy;

          (iii) such Holder or Holders offer and, if requested, provide to the
     Trustee indemnity satisfactory to the Trustee against any loss, liability
     or expense;

          (iv)  the Trustee does not comply with the request within 60 days
     after receipt of the request and the offer and the provision of indemnity;
     and

          (v) during such 60-day period the Holders of a majority in principal
     amount of the Outstanding Securities of such series do not give the Trustee
     a direction inconsistent with the request.

A Holder may not use this Indenture to prejudice the rights of another Holder or
to obtain a preference or priority over another Holder.

Section 707.   Rights of Holders to Receive Payment>>.
               --------------------------------------

     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 premium, if any) and (subject to Section 307)
interest on such Security on the Stated Maturity or Maturities expressed in such
Security (or, in the case of redemption, on the Redemption Date, or, in the case
of a repurchase right at the option of the Holder, if any, on the Repurchase
Date specified pursuant to Section 301) 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 708.   Collection Suit by Trustee>>.
               ----------------------------

     If an Event of Default with respect to the Securities of any series
specified in Section 701(i) or (ii) occurs and is continuing, the Trustee is
authorized to recover judgment in its own name and as trustee of an express
trust against the Company or any other obligor for the whole amount of
principal, premium, if any, and interest remaining unpaid on the Securities of
such series and interest on overdue principal and, to the extent lawful,
interest, premium and such further amount as shall be sufficient to cover the
costs and expenses of collection, including the costs and expenses of
collection, including the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel.

Section 709.   Trustee May File Proofs of Claim>>.
               ----------------------------------

     The Trustee is authorized to file such proofs of claim and other papers or
documents as may be necessary or advisable in order to have the claims of the
Trustee (including any claim for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel) and the
Holders allowed in any judicial proceedings relative to the Company (or any
other obligor upon the Securities), its creditors or its property and shall be
entitled and empowered to collect, receive and distribute any money or other
property payable or deliverable on any such claims and any custodian 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 make such payments directly
to the Holders, to pay to the Trustee any amount due to it for the compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel, and
any other amounts due the Trustee under Section 808 hereof. To the extent that
the payment of any such compensation, expenses, disbursements and advances of
the Trustee, its agents and counsel, and any other amounts due the Trustee under
Section 808 hereof out of the estate in any such proceeding, shall be denied for
any reason, payment of the same shall be secured by a Lien on, and shall be paid
out of, any and all distributions, dividends, money, securities and other
properties which the Holders may be entitled to receive in such proceeding
whether in liquidation or under any plan of reorganization or arrangement or
otherwise. Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Holder any plan of
reorganization, arrangement, adjustment or composition affecting the Securities
of any series or the rights of any Holder thereof, or to authorize the Trustee
to vote in respect of the claim of any Holder in any such proceeding.

Section 710.   Priorities>>.
               ------------

     If the Trustee collects any money with respect to the Securities of any
series pursuant to this Article, it shall pay out the money in the following
order:

     First: to the Trustee, its agents and attorneys for amounts due under
Section 808, including payment of all compensation, expenses and liabilities
incurred, and all advances made, by the Trustee and the costs and expenses of
collection;

Section 801.   Duties of Trustee>>.

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

               (ii)  With respect to the Securities of any series, except during
          the continuance of an Event of Default actually known to a Responsible
          Officer of the Trustee:

                     (a) the duties of the Trustee shall be determined solely by
               the express provisions of this Indenture or the TIA and the
               Trustee need perform only those duties that are specifically set
               forth in this Indenture or the TIA and no others, and no implied
               covenants or obligations shall be read into this Indenture
               against the Trustee, and

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

               (iii) The Trustee may not be relieved from liabilities for its
          own negligent action, its own negligent failure to act, or its own
          willful misconduct, except that:

                     (a) this paragraph does not limit the effect of paragraph
               (ii) of this Section;

                                       37

<PAGE>

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

                     (c) the Trustee shall not be liable with respect to any
               action it takes or omits to take in good faith in accordance with
               a direction received by it pursuant to Section 705 hereof.

               (iv)  Whether or not therein expressly so provided, every
          provision of this Indenture that in any way relates to the Trustee is
          subject to paragraphs (i), (ii), and (iii) of this Section.

               (v)   No provision of this Indenture shall require the Trustee to
          expend or risk its own funds or incur any liability. The Trustee may
          refuse to perform any duty or exercise any right or power unless it
          receives indemnity satisfactory to it against any loss, liability or
          expense.

               (vi)  The Trustee shall not be liable for interest on any money
          received by it except as the Trustee may agree in writing with the
          Company. Money held in trust by the Trustee need not be segregated
          from other funds except to the extent required by law.

Section 802.   Rights of Trustee>>.
               -------------------

               (i)   The Trustee may conclusively rely upon any document
          believed by it to be genuine and to have been signed or presented by
          the proper Person. The Trustee need not investigate any fact or matter
          stated in any such document.

               (ii)  Any request or direction of the Company mentioned herein
          shall be sufficiently evidenced by a Company Request or Company Order
          or as otherwise expressly provided herein and any resolution of the
          Board of Directors may be sufficiently evidenced by a Board
          Resolution.

               (iii) Before the Trustee acts or refrains from acting, it may
          require an Officers' Certificate or an Opinion of Counsel or both. The
          Trustee shall not be liable for any action it takes or omits to take
          in good faith in reliance on such Officers' Certificate or Opinion of
          Counsel. The Trustee may consult with counsel of its selection and the
          advice of such counsel or any Opinion of Counsel shall be full and
          complete authorization and protection from liability in respect of any
          action taken, suffered or omitted by it hereunder in good faith and in
          reliance thereon.

               (iv)  The Trustee may act through its attorneys and agents and
          shall not be responsible nor liable for the misconduct or negligence
          of any agent appointed with due care.

               (v)   The Trustee shall not be liable for any action it takes or
          omits to take in good faith which it believes to be authorized or
          within its rights or powers conferred upon it by this Indenture.

Section 803.   Individual Rights of Trustee>>.
               ------------------------------

     The Trustee in its individual or any other capacity may become the owner or
pledgee of Securities and may otherwise deal with the Company or any Affiliate
of the Company with the same rights it would have if it were not Trustee,
Authenticating Agent, Paying Agent, Security Registrar or such other agent. Any
Agent may do the same with like rights. However, the Trustee is subject to
Sections 812 and 813 hereof.

Section 804.   Trustee's Disclaimer>>.
               ----------------------

     The Trustee and the Authenticating Agent shall not be responsible for and
make no representation as to the validity or adequacy of this Indenture or the
Securities of any series, nor shall the Trustee or the Authenticating Agent be
accountable for the Company's use of the proceeds from the Securities or any
money paid to the Company or upon the Company's direction under any provision of
this Indenture, nor shall it or the Authenticating Agent be responsible for the
use or application of any money received by any Paying Agent other than the
Trustee, nor shall it be responsible for any statement or recital herein or any
statement in the Securities of any series or any other document in connection
with the sale of the Securities or pursuant to this Indenture other than its
certificate of authentication.

Section 805.   Notice of Defaults>>.
               --------------------

     If a Default or Event of Default with respect to the Securities of any
series occurs and is continuing and if it is actually known to a Responsible
Officer of the Trustee, the Trustee shall mail to Holders of such Securities a
notice of the Default or Event of Default within 90 days after it occurs. Except
in the case of a Default or Event of Default in payment on any Security of any
series or in the payment of any sinking fund installment with respect to the
Securities of such series, the Trustee may withhold the notice if and so long as
a committee of its Responsible Officers in good faith determines that
withholding the notice is in the interests of the Holders of Securities of such
series.

Section 806.   Preservation of Information>>.
               -----------------------------

     The Trustee shall preserve, in as current a form as is reasonably
practicable, the names and addresses of Holders of such series of Securities
received by the Trustee in its capacity as Security Registrar.

Section 807.   Reports by Trustee to Holders>>.
               -------------------------------

     Within 60 days after ________ of each year commencing with the later of
_________, ____ or the first _________ after the first issuance of Securities
pursuant to this Indenture, the Trustee shall mail to the Holders of Securities
of all series a brief report dated as of such reporting date that complies with
TIA Section 313(a) (but if no event described in TIA Section 313(a) has occurred
within the twelve months preceding the reporting date, no report need be
transmitted). The Trustee also shall comply with TIA Section 313(b). The Trustee
shall also transmit by mail all reports as required by TIA Section 313(c).

                                       39

<PAGE>

     A copy of each report at the time of its mailing to the Holders shall be
mailed to the Company and filed with the Commission and each stock exchange on
which the Securities are listed. The Company shall promptly notify the Trustee
when the Securities are listed on any stock exchange or delisted therefrom.

Section 808.   Compensation and Indemnity>>.
               ----------------------------

     The Company shall pay to the Trustee from time to time such compensation
for its acceptance of this Indenture and services hereunder mutually
satisfactory to the Company and Trustee. The Trustee's compensation shall not be
limited by any law on compensation of a trustee of an express trust. The Company
shall reimburse the Trustee promptly upon request for all disbursements,
advances and expenses incurred or made by it in addition to the compensation for
its services. Such expenses shall include the reasonable compensation,
disbursements and expenses of the Trustee's agents and counsel.

     The Company shall fully indemnify the Trustee against any and all losses,
liabilities, claims, damages or expenses (including taxes other than taxes based
on the income of the Trustee) incurred by it arising out of or in connection
with the acceptance of its duties and the administration of the trusts under
this Indenture, except as set forth below. The Trustee shall notify the Company
promptly of any claim for which it may seek indemnity. Failure by the Trustee to
so notify the Company shall not relieve the Company of its obligations
hereunder. The Company shall defend the claim and the Trustee shall cooperate in
the defense. The Trustee may have separate counsel of its own selection and the
Company shall pay the reasonable fees and expenses of such counsel. The Company
need not pay for any settlement made without its consent, which consent shall
not be unreasonably withheld.

     The obligations of the Company under this Section 808 shall survive the
satisfaction and discharge of this Indenture.

     The Company need not reimburse any expense or indemnify against any loss or
liability incurred by the Trustee through its own negligence or willful
misconduct.

     To secure the Company's payment obligations in this Section 808, the
Trustee shall have a Lien prior to the Securities on all money or property held
or collected by the Trustee, except that held in trust to pay principal and
interest on the Securities of any series. Such Lien shall survive the
satisfaction and discharge of this Indenture.

     When the Trustee incurs expenses or renders services after an Event of
Default specified in Section 701(viii) or (ix) hereof occurs, the expenses and
the compensation for the services (including the fees and expenses of its agents
and counsel) are intended to constitute expenses of administration under any
Bankruptcy Law.

Section 809.   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 810.

                                       40

<PAGE>

     (b)  The Trustee may resign at any time with respect to the Securities of
one or more series by giving written notice thereof to the Company specifying
its intention to resign, the applicable series affected by such resignation, the
reason therefor and the date upon which such resignation shall become effective.
Notwithstanding the foregoing, unless the reason for such resignation is a
conflict pursuant to TIA Section 310(b) as provided in Section 812 hereof, the
Trustee must resign with respect to all Securities if the Trustee resigns with
respect to any series of Securities. If the instrument of acceptance by a
successor Trustee required by Section 810 shall not have been delivered to the
Trustee within 60 days after the giving of such notice of resignation, the
resigning Trustee may petition at the expense of the Company any court of
competent jurisdiction for the appointment of a successor Trustee with respect
to the Securities of such series.

     (c)  The 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
Company.

     (d)  If at any time:

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

               (2)  the Trustee shall cease to be eligible under Section 812 and
          shall fail to resign after written request therefor by the Company or
          by any such Holder, or

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

then, in any such case, (i) the Company by a Board Resolution may remove the
Trustee with respect to any one or more series of Securities or all Securities,
or (ii) subject to Section 711, 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 such series of 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 Company, by a Board Resolution,
shall promptly appoint a successor Trustee or Trustees with respect to the
Securities of that or those series (it being understood that any such successor
Trustee may be appointed with respect to the Securities of one or more or all of
such series and that at any time there shall be only one Trustee with respect to
the Securities of any particular series). If, within one year after such
resignation, removal or incapability, or the occurrence of such vacancy, a
successor Trustee with respect to the Securities of any series shall be
appointed by Act of the Holders of a majority in principal amount of the
Outstanding

                                       41

<PAGE>

Securities of such series delivered to the Company and the retiring Trustee, the
successor Trustee so appointed shall, forthwith upon its acceptance of such
appointment in accordance with the applicable requirements of Section 810,
become the successor Trustee with respect to the Securities of such series and
to that extent supersede the successor Trustee appointed by the Company. If no
successor Trustee with respect to the Securities of any series shall have been
so appointed by the Company or the Holders and accepted appointment in the
manner required by Section 810, any Holder who has been a bona fide Holder of a
Security of such series for at least six months may, on behalf of himself and
all others similarly situated, petition any court of competent jurisdiction for
the appointment of a successor Trustee with respect to the Securities of such
series.

     (f)  The Company shall give notice of each resignation and each removal of
the Trustee with respect to the Securities of any series and each appointment of
a successor Trustee with respect to the Securities of any series by mailing
written notice of such event by first-class mail, postage prepaid, to all
Holders of Securities of such series as their names and addresses appear in the
Security Register. 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 810.   Acceptance of Appointment by Successor>>.
               ----------------------------------------

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

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

                                       42

<PAGE>

by any other such Trustee; and upon the execution and delivery of such
supplemental indenture the resignation or removal of the retiring Trustee shall
become effective to the extent provided therein and each such successor Trustee,
without any further act, deed or conveyance, shall become vested with all the
rights, powers, trusts and duties of the retiring Trustee with respect to the
Securities of that or those series to which the appointment of such successor
Trustee relates; but, on request of the Company or any successor Trustee, such
retiring Trustee shall duly assign, transfer and deliver to such successor
Trustee all property and money held by such retiring Trustee hereunder with
respect to the Securities of that or those series to which the appointment of
such successor Trustee relates. Whenever there is a successor Trustee with
respect to one or more (but less than all) series of securities issued pursuant
to this Indenture, the terms "Indenture" and "Securities" shall have the
meanings specified in the provisos to the respective definitions of those terms
in Section 101 which contemplate such situation.

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

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

Section 811.   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; in case
any of the Securities shall not have been authenticated by the Trustee then in
office, any successor by merger, conversion or consolidation to such Trustee may
authenticate such Securities either in the name of such predecessor hereunder or
in the name of the successor Trustee; and in all such cases such certificates
shall have the full force which it is anywhere in the Securities or in this
Indenture provided that the certificate of the Trustee shall have; provided,
however, that the right to adopt the certificate of authentication of any
predecessor Trustee or to authenticate Securities in the name of any predecessor
Trustee shall apply only to its successor or successors by merger, conversion or
consolidation.

Section 812.   Eligibility; Disqualification>>.
               -------------------------------

     There shall at all times be a Trustee hereunder which shall be a
corporation organized and doing business under the laws of the United States of
America or of any state thereof authorized under such laws to exercise corporate
trustee power, shall be subject to supervision or

                                       43

<PAGE>

examination by Federal or state authority and shall have a combined capital and
surplus of at least $50 million as set forth in its most recent published annual
report of condition.

     This Indenture shall always have a Trustee who satisfies the requirements
of TIA Section 310(a)(1), (2) and (5). The Trustee is subject to TIA Section
310(b).

Section 813.   Preferential Collection of Claims Against Company>>.
               ---------------------------------------------------

     The Trustee is subject to TIA Section 311(a), excluding any creditor
relationship listed in TIA Section 311(b). A Trustee who has resigned or been
removed shall be subject to TIA Section 311(a) to the extent indicated therein.

Section 814.   Appointment of Authenticating Agent>>.
               -------------------------------------

     At any time when any of the Securities remain Outstanding the Trustee, with
the concurrence of the Company, may appoint an Authenticating Agent or Agents
with respect to one or more series of Securities which shall be authorized to
act on behalf of the Trustee to authenticate Securities of such series, and
Securities so authenticated shall be entitled to the benefits of this Indenture
and shall be valid and obligatory for all purposes as if authenticated by the
Trustee hereunder. Wherever reference is made in this Indenture to the
authentication and delivery of Securities by the Trustee or the Trustee's
certificate of authentication, such reference shall be deemed to include
authentication and delivery on behalf of the Trustee by an Authenticating Agent
and a certificate of authentication executed on behalf of the Trustee by an
Authenticating Agent. Each Authenticating Agent shall be acceptable to the
Company and shall at all times be a Corporation organized and doing business
under the laws of the United States of America, any State thereof or the
District of Columbia authorized under such laws to act as Authenticating Agent,
having a combined capital and surplus of not less than $50,000,000 and subject
to supervision or examination by Federal, State or District of Columbia
authority. If such Authenticating Agent publishes reports of condition at least
annually, pursuant to law or to the requirements of said supervising or
examining authority, then for 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 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.

     An Authenticating Agent may resign at any time by giving written notice
thereof to the Trustee and to the Company. The Trustee may at anytime terminate
the agency of an Authenticating Agent by giving written notice thereof to such
Authenticating Agent and to the

                                       44

<PAGE>

Company. Upon receiving such a notice of resignation or upon such a termination,
or in case at any time such Authenticating Agent shall cease to be eligible in
accordance with the provisions of this Section, the Trustee may appoint a
successor Authenticating Agent which shall be acceptable to the Company and
shall mail written notice of such appointment by first class mail, postage
prepaid, to all Holders of Securities of the series with respect to which such
Authenticating Agent will serve, as their names and addresses appear in the
Security Register. 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.

     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 reimbursement for such payments subject to Section 808.

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

                             DISCHARGE OF INDENTURE

Section 901.   Defeasance and Discharge of this Indenture and the Securities>>.
               ---------------------------------------------------------------

     The Company may, at the option of its Board of Directors evidenced by a
Board Resolution set forth in an Officers' Certificate, at any time, with
respect to the Securities of any series, elect to have either Section 902 or 903
be applied to the Outstanding Securities of such series upon compliance with the
conditions set forth below in this Article 9.

Section 902.   Legal Defeasance and Discharge>>.
               --------------------------------

     Upon the Company's exercise under Section 901 of the option applicable to
this Section 902, the Company shall be deemed to have been discharged from its
obligations with respect to the Outstanding Securities of any series on the date
the conditions set forth below are satisfied with respect to such series
(hereinafter, "Legal Defeasance"). For this purpose, such Legal Defeasance means
that the Company shall be deemed to have paid and discharged the entire
Indebtedness represented by the Outstanding Securities of such series, which
shall thereafter be deemed to be "Outstanding" only for the purposes of Section
905 and the other Sections of this Indenture referred to in clauses (i) and (ii)
of this Section 902, and to have satisfied all its other obligations under the
Securities of such series and this Indenture as it relates to such series (and
the Trustee, on demand of and at the expense of the Company, shall execute
proper instruments acknowledging the same), except for the following which shall
survive until otherwise terminated or discharged hereunder: (i) the rights of
Holders of Outstanding Securities of such series to receive solely from the
trust fund described in Section 904, and as more fully set forth in such
Section, payments in respect of the principal of, premium, if any, and interest
on such Securities when such payments are due, (ii) the Company's obligations
with respect to such Securities under Sections 305, 306 and 502, (iii) the
rights, powers, trusts, duties and immunities of the Trustee hereunder,
including, without limitation, the Trustee's rights under Section 808, and the
Company's obligations in connection therewith and (iv) this Article 9. Subject
to compliance with this Article 9, the Company may exercise its option under
this Section 902 notwithstanding the prior exercise of its option under Section
903 with respect to the Securities of such series.

Section 903.   Covenant Defeasance>>.
               ---------------------

     Unless specifically otherwise provided in a Board Resolution, Officers'
Certificate or indenture supplemental hereto provided pursuant to Section 301,
upon the Company's exercise under Section 901 of the option applicable to this
Section 903, the Company shall be released from its obligations under the
covenants contained in Sections 504, 505 and 506 and Article 6 and any covenants
created as contemplated by Section 301(12) with respect to the Outstanding
Securities of any series on and after the date the conditions set forth below
are satisfied with respect to such series (hereinafter, "Covenant Defeasance"),
and the Securities of such series shall thereafter be deemed not "outstanding"
for the purposes of any direction, waiver, consent or declaration or act of
Holders of such Securities (and the consequences of any thereof) in connection
with such covenants, but shall continue to be deemed "Outstanding" for all other
purposes hereunder (it being understood that such Securities shall not be deemed
outstanding for

                                       46

<PAGE>

accounting purposes). For this purpose, such Covenant Defeasance means that,
with respect to the Outstanding Securities of any series, the Company may omit
to comply with and shall have no liability in respect of any term, condition or
limitation set forth in any such covenant, whether directly or indirectly, by
reason of any reference elsewhere herein to any such covenant or by reason of
any reference in any such covenant to any other provision herein or in any other
document and such omission to comply shall not constitute a Default or an Event
of Default with respect to such series of Securities under Section 701(iv) or
(v) but, except as specified above, the remainder of this Indenture and such
Securities shall be unaffected thereby. In addition, upon the Company's exercise
under Section 901 of the option applicable to this Section 903, subject to the
satisfaction of the conditions set forth in Section 904, any failure or omission
to comply with such covenants shall not constitute a Default or Event of Default
with respect to the Securities.

Section 904.   Conditions to Legal or Covenant Defeasance>>.
               --------------------------------------------

     The following shall be the conditions to application of either Section 902
or Section 903 to the Outstanding Securities of any series:

          (i)   The Company shall irrevocably have deposited or caused to be
     deposited with the Trustee (or another trustee satisfying the requirements
     of Section 812 who shall agree to comply with the provisions of this
     Article 9 applicable to it) as trust funds in trust for the purpose of
     making the following payments, specifically pledged as security for, and
     dedicated solely to, the benefit of the Holders of the Securities of such
     series, (a) cash in U.S. Dollars in an amount, or (b) non-callable
     Government Securities which through the scheduled payment of principal and
     interest in respect thereof in accordance with their terms will provide,
     not later than one day before the due date of any payment, cash in U.S.
     Dollars in an amount, or (c) a combination thereof, in such amounts, as
     will be sufficient, in the opinion of a nationally recognized firm of
     independent public accountants expressed in a written certification thereof
     delivered to the Trustee, to pay and discharge and which shall be applied
     by the Trustee (or other qualifying trustee) to pay and discharge (A) the
     principal of, premium, if any, and interest on the Outstanding Securities
     of such series on the Stated Maturity or on the applicable Redemption Date,
     as the case may be, of such principal or installment of principal, premium,
     if any, or interest on the day on which such payments are due and payable
     and (B) any mandatory sinking fund payments or analogous payments
     applicable to the Securities of such series on the day on which such
     payments are due and payable in accordance with the terms of this Indenture
     and such Securities; provided that the Trustee shall have been irrevocably
     instructed to apply such money or the proceeds of such non-callable
     Government Securities to said payments with respect to the Securities of
     such series.

          (ii)  In the case of an election under Section 902, the Company shall
     have delivered to the Trustee an Opinion of Counsel in the United States
     reasonably satisfactory to the Trustee confirming that (a) the Company has
     received from, or there has been published by, the Internal Revenue Service
     a ruling or (b) since the date hereof, there has been a change in the
     applicable federal income tax law, in either case to the effect that, and
     based thereon such opinion shall confirm that, the Holders of the
     Outstanding Securities of such series will not recognize income, gain or
     loss for federal

                                       47

<PAGE>

     income tax purposes as a result of such Legal Defeasance and will be
     subject to federal income tax on the same amounts, in the same manner and
     at the same times as would have been the case if such Legal Defeasance has
     not occurred.

          (iii) In the case of an election under Section 903, the Company shall
     have delivered to the Trustee an Opinion of Counsel in the United States to
     the effect that the Holders of the Outstanding Securities of such series
     will not recognize income, gain or loss for federal income tax purposes as
     a result of such Covenant Defeasance and will be subject to Federal income
     tax in the same amount, in the same manner and at the same times as would
     have been the case if such Covenant Defeasance had not occurred.

          (iv)  No Default or Event of Default with respect to the Securities of
     such series shall have occurred and be continuing on the date of such
     deposit or, in so far as Subsection 701(viii) or 701(ix) is concerned, at
     any time in the period ending on the 91st day after the date of such
     deposit (it being understood that this condition shall not be deemed
     satisfied until the expiration of such period).

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

          (vi)  In the case of an election under either Section 902 or 903, the
     Company shall have delivered to the Trustee an Opinion of Counsel to the
     effect that after the 91st day following the deposit, assuming no filing by
     or against the Company as a "debtor" in a proceeding under any applicable
     Bankruptcy Law, the trust funds will not be subject to the effect of any
     applicable Bankruptcy Law.

          (vii) In the case of an election under either Section 902 or 903, the
     Company shall have delivered to the Trustee an Officers' Certificate
     stating that the deposit made by the Company pursuant to its election under
     Section 902 or 903 was not made by the Company with the intent of
     preferring the Holders of the series of Securities to be defeased over
     other creditors of the Company or with the intent of defeating, hindering,
     delaying or defrauding creditors of the Company or others.

          (viii) The Company shall have delivered to the Trustee an Officers'
     Certificate and an Opinion of Counsel in the United States, each stating
     that all conditions precedent provided for relating to either the Legal
     Defeasance under Section 902 or the Covenant Defeasance under Section 903
     (as the case may be) have been complied with as contemplated by this
     Section 904.

Section 905.   Deposited Money and Government Securities to be Held in Trust;
               --------------------------------------------------------------
               Other Miscellaneous Provisions>>.
               --------------------------------

     Subject to Section 906, all money and non-callable Government Securities
(including the proceeds thereof) deposited with the Trustee (or other qualifying
trustee, collectively for purposes of this Section 905, the "Trustee") pursuant
to Section 904 in respect of the Outstanding Securities of any series shall be
held in trust and applied by the Trustee, in

                                       48

<PAGE>

accordance with the provisions of such Securities and this Indenture, to the
payment, either directly or through any Paying Agent (including the Company
acting as Paying Agent) as the Trustee may determine, to the Holders of the
Securities of such series of all sums due and to become due thereon in respect
of principal, premium, if any, and interest, but such money need not be
segregated from other funds except to the extent required by law.

     The Company shall pay and indemnify the Trustee against any tax, fee or
other charge imposed on or assessed against the cash or non-callable Government
Securities deposited pursuant to Section 904 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 the Outstanding Securities of such
series.

     Anything in this Article 9 to the contrary notwithstanding, the Trustee
shall deliver or pay to the Company from time to time upon the Company's request
any money or non-callable Government Securities held by it as provided in
Section 904 which, in the opinion of a nationally recognized firm of independent
public accountants expressed in a written certification thereof delivered to the
Trustee (which may be the opinion delivered under Section 904(i)), are in excess
of the amount thereof which would then be required to be deposited to effect an
equivalent Legal Defeasance or Covenant Defeasance.

Section 906.   Repayment to Company>>.
               ----------------------

     Any money deposited with the Trustee or any Paying Agent, or then held by
the Company, in trust for the payment of the principal of, premium, if any, or
interest on any Security and remaining unclaimed for two years after such
principal, and premium, if any, or interest has become due and payable shall be
paid to the Company on its request or (if then held by the Company) shall be
discharged from such trust; and the Holder of such Security shall thereafter, as
an unsecured general creditor, look only to the Company for payment thereof, and
all liability of the Trustee or such Paying Agent with respect to such trust
money, and all liability of the Company as trustee thereof, shall thereupon
cease; provided, however, that the Trustee or such Paying Agent, before being
required to make any such repayment, may at the expense of the Company cause to
be published once, in the New York Times and The Wall Street Journal (national
edition), notice that such money remains unclaimed and that, after a date
specified therein, which shall not be less than 30 days from the date of such
notification or publication, any unclaimed balance of such money then remaining
will be repaid to the Company.

Section 907.   Reinstatement>>.
               ---------------

     If the Trustee or Paying Agent is unable to apply any U.S. Dollars or
non-callable Government Securities in accordance with Section 902 or 903, as the
case may be, by reason of any order or judgment of any court or governmental
authority enjoining, restraining or otherwise prohibiting such application, then
the Company's obligations under this Indenture and the Securities of any series
to be defeased shall be revived and reinstated as though no deposit had occurred
pursuant to Section 902 or 903 until such time as the Trustee or Paying Agent is
permitted to apply all such money in accordance with Section 902 or 903, as the
case may be; provided, however, that, if the Company makes any payment of
principal of, premium, if any, or interest on any such Security following the
reinstatement of its obligations, the Company shall be

                                       49

<PAGE>

subrogated to the rights of the Holders of such Security to receive such payment
from the money held by the Trustee or Paying Agent.

               ----------------------------

     Without the consent of any Holders, the Company, when authorized by or

     and in the Securities; or

     more specified series) or to surrender any right or power herein conferred
     upon the Company; or

          (iii) to add any additional Events of Default (and if such Events of

     benefit of such series); or

          (iv)  to add to or change any of the provisions of this Indenture to

     issuance of Securities of any series in certificated or uncertificated
     form; or

          (v)   to add to, change or eliminate any of the provisions of this
     Indenture in respect of one or more series of Securities, provided that any
     such addition, change or elimination (i) shall neither (A) apply to any
     Security of any series created prior to the execution of such supplemental
     indenture and entitled to the benefit of such provision nor (B) modify the
     rights of the Holder of any such Security with respect to such provision or
     (ii) shall become effective only when there is no such Security
     Outstanding; or

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

          facilitate the administration of the trusts hereunder by more than one
          Trustee, pursuant to the requirements of Section 810; or

          (ix)  to cure any ambiguity or defect in or to correct or supplement
     any provision herein which may be inconsistent with any other provision in
     this Indenture or any Security of any series, or to make any other
     provisions with respect to matters or questions arising under this
     Indenture, provided such action shall not adversely affect the interests of
     the Holders of Securities of any series in any material respect; or

          (x)   to comply with requirements of the Commission in order to effect
     or maintain the qualification of this Indenture under the TIA.

Section 1002.  With Consent of Holders>>.
               -------------------------

     With the consent of the Holders of not less than a majority in aggregate
principal amount of the Securities of all series at the time Outstanding
affected by such amendment or supplemental indenture (voting as one class), by
Act of said Holders delivered to the Company and the Trustee, the Company, when
authorized by a Board Resolution, and the Trustee may amend this Indenture or
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 manner the rights of the
Holders of Securities of such series under this Indenture; provided, however,
that no such amendment or supplemental indenture shall, without the consent of
the Holder of each Outstanding Security affected thereby,

          (i)   change the Stated Maturity of the principal of, or any
     installment of principal of or interest on, any such affected 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 that would be due and
     payable upon a declaration of acceleration of the Maturity thereof pursuant
     to Section 702, or change any Place of Payment where, or the coin or
     currency in which, any such Security or any premium or the interest thereon
     is payable, or impair the right to institute suit for the enforcement of
     any such payment on or after the Stated Maturity thereof (or, in the case
     of redemption or repayment, on or after the Redemption Date or any
     repayment date), or

          (ii)  reduce the percentage in principal amount of the Outstanding
     Securities of any series, the consent of whose Holders is required for any
     modifications or amendments to the Indenture with respect to such series or
     to the terms and conditions of such series or to approve a supplemental
     indenture with respect to such series, or the consent of whose Holders is
     required for any waiver with respect to such series of compliance with
     certain provisions of this Indenture or certain defaults hereunder and
     their consequences provided for in this Indenture, or

          (iii) modify any of the provisions of Sections 704 or 707 or this
     Section 1002 or Article 8, except to increase any such percentage or to
     provide that certain other provisions of this Indenture cannot be modified
     or waived without the consent of the Holder of each Outstanding Security
     affected thereby; provided however, that this clause

                                       51

<PAGE>

          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 1002 and Article 8, or the deletion of this proviso,
          in accordance with the requirements of Sections 810(b) and 1001(viii).

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

     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 1003.  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 801) shall be fully protected in conclusively relying
upon, an Opinion of Counsel stating that the execution of such supplemental
indenture is authorized or permitted by this Indenture. The Trustee may, but
shall not be obligated to, enter into any such supplemental indenture which
affects the Trustee's own rights, duties or immunities under this Indenture or
otherwise.

Section 1004.  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 of the series affected thereby theretofore or thereafter
authenticated and delivered hereunder shall be bound thereby to the extent
provided therein.

Section 1005.  Compliance with TIA>>.
               ---------------------

     Every amendment or supplement to this Indenture or the Securities of any
series shall be set forth in a supplemental indenture that complies with the TIA
as then in effect.

Section 1006.  Revocation and Effect of Consents>>.
               -----------------------------------

     Until an amendment, supplemental waiver or waiver becomes effective, a
consent to it by a Holder is a continuing consent by the Holder and every
subsequent Holder of a Security or portion of a Security that evidences the same
debt as the consenting Holder's Security, even if notation of the consent is not
made on any Security. A supplemental indenture, amendment or waiver becomes
effective in accordance with its terms and thereafter binds every Holder of the
series of Securities to which such amendment, supplemental waiver or waiver
relates.

                                       52

<PAGE>

     The Company may, but shall not be obligated to, fix a record date for
determining which Holders of the Securities of any series must consent to such
amendment or waiver. If the Company fixes a record date, the record date shall
be fixed at (i) the later of 30 days prior to the first solicitation of such
consent or the date of the most recent list of Holders furnished to the Trustee
prior to such solicitation or (ii) such other date as the Company shall
designate.

Section 1007.  Reference in Securities to Supplemental Indentures>>.
               ----------------------------------------------------

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

Section 1008.  Notice of Supplemental Indentures>>.
               -----------------------------------

     Promptly after the execution by the Company and the Trustee of any
supplemental indenture pursuant to the provisions of Section 1002, the Company
shall give notice thereof to the Holders of each Outstanding Security so
affected, pursuant to Section 108, setting forth in general terms the substance

Section 1101.  Applicability of Article>>.
               --------------------------

     Unless otherwise specifically provided for in accordance with Section 301
with respect to any series of Securities, the Company shall have no sinking fund
obligations with respect to Securities of any series. The sinking fund
obligations as to any series of Securities for which such obligations exist
shall be as provided by the terms of such series of Securities as specifically
established in accordance with Section 301 and, except as otherwise provided by
such terms, as provided in this Article.

     The minimum amount of any sinking fund payment provided for by the terms of
Securities of any series is herein referred to as a "mandatory sinking fund
payment", and any payment in excess of such minimum amount provided for by the
terms of Securities of any series is herein referred to as an "optional sinking
fund payment". If provided for by the terms of Securities of any series, the
cash amount of any sinking fund payment may be subject to reduction as provided
in Section 1102. Each sinking fund payment shall be applied to the redemption of
Securities of any series as provided for by the terms of Securities of such
series.

the election of the Company pursuant to the terms of

                                       53

payments pursuant to the terms of such Securities, in each case in satisfaction
of all or any part of any sinking fund payment with respect to the Securities of
like tenor of such series required to be made pursuant to the terms of such
Securities as provided for by the terms of such series; provided that such
Securities have not been previously so credited. Such Securities shall be
received and credited for such purpose by the Trustee at the Redemption Price
specified in such Securities for redemption through operation of the sinking
fund and the amount of such sinking fund payment shall be reduced accordingly.
Such Securities shall be first applied to the sinking fund payment next due and
any excess shall be applied to the following sinking fund payments in the order
they are due.

Section 1103.  Redemption of Securities for Sinking Fund>>.
               -------------------------------------------

     Not less than 60 days prior to each sinking fund payment date for
Securities of like tenor of a series, the Company shall 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 of like tenor of that series pursuant to Section 1102 and, at the
time of delivery of such Officers' Certificate, will also deliver to the Trustee
any Securities to be so delivered. Not less than 30 days before each such
sinking fund payment date the Trustee shall select the Securities to be redeemed
upon such sinking fund payment date in the manner specified in Section 403 and
cause notice of the redemption thereof to be given in the name of and at the
expense of the Company in the manner provided in Section 404. Such notice having

               --------------------------

     Unless otherwise specifically provided for in accordance with Section 301

obligations with respect to Securities of any series. Securities of any series
which are repurchasable before their Stated Maturity at the option of the
Holders in accordance with their terms as specifically established in accordance
with Section 301 shall be repurchasable in accordance with their terms and,
except as otherwise provided by such terms, in accordance with this Article.

Section 1202.  Notice of Repurchase Date>>.
               ---------------------------

     Notice of any Repurchase Date with respect to Securities of any series

     The notice as to Repurchase Date shall state:

               (1)  the Repurchase Date;

                                       54

<PAGE>

               (2)  the Repurchase Price;

               (3)  the place or places where such Securities are to be
          surrendered for payment of the Repurchase Price and the date by which
          such Securities must be so surrendered in order to be repurchased;

               (4)  a description of the procedure which a Holder must follow to
          exercise a repurchase right;

               (5)  that exercise of the option to elect repurchase is
          irrevocable; and

               (6)  the CUSIP numbers.

No failure of the Company to give the foregoing notice shall limit any Holder's
right to exercise a repurchase right.

Section 1203.  Deposit of Repurchase Price>>.
               -----------------------------

     On or prior to the Repurchase Date, the Company shall deposit with the
Trustee or with a Paying Agent (or, if the Company is acting as its own paying
Agent, segregate and hold in trust as provided in Section 503) the amounts
required to be deposited in accordance with the applicable repurchase right
provisions or, if no such amount is specified, an amount of money sufficient to
pay the Repurchase Price of and (unless the Repurchase Date shall be an Interest
Payment Date) accrued interest, if any, on all of the Securities of such series
which are to be repurchased on that date.

Section 1204.  Securities Payable on Repurchase Date>>.
               ---------------------------------------

     The form of option to elect repurchase having been delivered as specified
in the form of Security for such series as provided in Article 2, the Securities
of such series so to be repurchased shall, on the Repurchase Date, become due
and payable at the Repurchase Price applicable thereto and from and after such
date (unless the Company shall default in the payment of the Repurchase Price
and accrued interest) such Securities shall cease to bear interest. Upon
surrender of any such Security for repurchase in accordance with said notice,
such Security shall be paid by the Company at the Repurchase Price together with
accrued interest to the Repurchase Date; provided, however, that installments of
interest whose Stated Maturity is on or prior to such Repurchase Date shall be
payable to the Holders of such Securities, or one or more Predecessor
Securities, registered as such at the close of business on the relevant Regular
and Special Record Dates according to their terms and the provisions of Section
307.

     If the amount deposited in accordance with Section 1203 is insufficient to
pay the Repurchase Price of all of the Securities as to which the option to
elect repurchase exists under this Indenture and has been exercised, the Trustee
shall select the particular Securities to be repurchased on a pro rata basis
among all such Holders of all series of Securities having such repurchase right
and so exercising the option to elect repurchase (and in such manner as complies
with applicable legal and stock exchange requirements, if any). The Trustee
shall promptly notify the Company in writing of the Securities selected for
repurchase and the principal amount thereof. Securities and portions of them
selected shall be in amounts of $1,000

                                       55

<PAGE>

or whole multiples of $1,000. Except as provided in this paragraph, provisions
of this Indenture that apply to Securities to be repurchased also apply to
portions of Securities to be repurchased.

     If any such Security shall not be paid upon surrender thereof for
repurchase, the principal (and premium, if any) shall, until paid, bear interest
from the Repurchase Date at the rate prescribed therefor in such Security.

Section 1205.  Securities Repurchased in Part>>.
               --------------------------------

     Any Security which by its terms may be repurchased in part at the option of
the Holder and which is to be repurchased only in part, or which is repurchased
only in part in accordance with Section 1204, shall be surrendered at any office
or agency of the Company designated for that purpose pursuant to Section 502
(with, if the Company or the Trustee so requires, due endorsement by, or a
written instrument of transfer in form satisfactory to the Company and the
Trustee duly executed by, the Holder thereof or such Holder's attorney duly
authorized in writing), and the Company shall execute, and a Responsible Officer
of 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 unrepurchased
portion of the principal of the Security so surrendered. To the extent a series
of Securities represented by a Global Security is to be repurchased in part
only, a notation of such redemption shall be made by the Trustee in the schedule
of exchanges on the Global Security.
