<PAGE>
signed by such Holders in person or by an agent duly appointed in writing; and,
except as herein otherwise expressly provided, such action shall become
effective when such instrument or instruments are delivered to the Trustee and,
where it is hereby expressly required, to the Company. Such instrument or
instruments (and the action embodied therein and evidenced thereby) are herein
sometimes referred to as the "Act" of the Holders signing such instrument or
instruments. Proof of execution of any such instrument or of a writing
appointing any such agent shall be sufficient for any purpose of this Indenture
and (subject to Section 601) conclusive and may be relied upon by the Trustee,
the Company, and any agent of the Trustee or the Company, if made in the manner
provided in this Section.

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

         (c) The fact and date of the execution by any Person of any such
instrument or writing, or the authority of the Person executing the same, may
also be proved in any other manner which the Trustee deems sufficient and in
accordance with such reasonable rules as the Trustee may determine.

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

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

         (f) The Company may, but shall not be obligated to, set any day as a
record date for the purpose of determining the Holders of Outstanding Securities
entitled to give, make or take any request, demand, authorization, direction,
notice, consent, waiver or other action provided or permitted by this Indenture
to be given, made or taken by Holders of Securities, provided that the Company
may not set a record date for, and the provisions of this paragraph shall not
apply with respect to, the giving or making of any notice, declaration, request
or direction referred to in the next paragraph. If any record date is set
pursuant to this paragraph, the Holders of Outstanding Securities on such record
date, and no other Holders, shall be entitled to take the relevant action,
whether or not such Holders remain Holders after such record date; provided that
no such action shall be effective hereunder unless taken on or prior to the
applicable Expiration Date (as defined below) by Holders of the requisite
principal amount of Outstanding Securities on such record date. Nothing in this
paragraph shall be construed to prevent the Company from setting a new record
date for any action for which a record date has previously been

                                       10
<PAGE>
set pursuant to this paragraph (whereupon the record date previously set shall
automatically and with no action by any Person be cancelled and of no effect),
and nothing in this paragraph shall be construed to render ineffective any
action taken by Holders of the requisite principal amount of Outstanding
Securities on the date such action is taken. Promptly after any record date is
set pursuant to this paragraph, the Company, at its own expense, shall cause
notice of such record date, the proposed action by Holders and the applicable
Expiration Date to be given to the Trustee in writing and to each Holder of
Securities in the manner set forth in Section 106.

         The Trustee may set any day as a record date for the purpose of
determining the Holders of Outstanding Securities entitled to join in the giving
or making of (i) any Notice of Default, (ii) any declaration of acceleration
referred to in Section 502, (iii) any request to institute proceedings referred
to in Section 507(2) or (iv) any direction referred to in Section 512. If any
record date is set pursuant to this paragraph, the Holders of Outstanding
Securities on such record date, and no other Holders, shall be entitled to join
in such notice, declaration, request or direction, whether or not such Holders
remain Holders after such record date; provided that no such action shall be
effective hereunder unless taken on or prior to the applicable Expiration Date
by Holders of the requisite principal amount of Outstanding Securities on such
record date. Nothing in this paragraph shall be construed to prevent the Trustee
from setting a new record date for any action for which a record date has
previously been set pursuant to this paragraph (whereupon the record date
previously set shall automatically and with no action by any Person be cancelled
and of no effect), and nothing in this paragraph shall be construed to render
ineffective any action taken by Holders of the requisite principal amount of
Outstanding Securities on the date such action is taken. Promptly after any
record date is set pursuant to this paragraph, the Trustee, at the Company's
expense, shall cause notice of such record date, the proposed action by Holders
and the applicable Expiration Date to be given to the Company in writing and to
each Holder of Securities in the manner set forth in Section 106.

         With respect to any record date set pursuant to this Section, the party
hereto which sets such record dates may designate any day as the "Expiration
Date" and from time to time may change the Expiration Date to any earlier or
later day; provided that no such change shall be effective unless notice of the
proposed new Expiration Date is given to the other party hereto in writing, and
to each Holder of Securities in the manner set forth in Section 106, on or prior
to the existing Expiration Date. If an Expiration Date is not designated with
respect to any record date set pursuant to this Section, the party hereto which
set such record date shall be deemed to have initially designated the 180th day
after such record date as the Expiration Date with respect thereto, subject to
its right to change the Expiration Date as provided in this paragraph.
Notwithstanding the foregoing, no Expiration Date shall be later than the 180th
day after the applicable record date.

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

                                       11
<PAGE>
which may do so pursuant to such appointment with regard to all or any part of
such principal amount.

SECTION 105. 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 if made, given, furnished or filed to or with the
Trustee in writing at its Corporate Trust Office or

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

any such request, demand, authorization, direction, notice, consent, waiver or
Act of Holders unless given, furnished or filed as provided in this Section 105.

SECTION 106. Notice to Holders; Waiver.

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

         In case by reason of the suspension of regular mail service or by
reason of any other cause it shall be impracticable to give such notice by mail,
then such notification as shall be made with the written approval of the Trustee
shall constitute a sufficient notification for every purpose hereunder.

SECTION 107. Conflict with Trust Indenture Act.

         If any provision hereof limits, qualifies or conflicts with a provision
of the Trust Indenture Act which is required under such Act to be a part of and
govern this Indenture,

                                       12
<PAGE>
the latter provision shall control. If any provision of this Indenture modifies
or excludes any provision of the Trust Indenture Act which may be so modified or
excluded, the latter provision shall be deemed to apply to this Indenture as so
modified or to be excluded, as the case may be.

SECTION 108. Effect of Headings and Table of Contents.

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

SECTION 109. Successors and Assigns.

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

SECTION 110. Separability Clause.

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

SECTION 111. Benefits of Indenture.

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

SECTION 112. Governing Law; Waiver of Jury Trial.

FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL BY JURY
IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THE INDENTURE, THE

SECTION 113. Legal Holidays.

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

                                       13
<PAGE>
made on the Interest Payment Date or Redemption Date, or at the Maturity or
Stated Maturity and no interest shall accrue for the period from and after such
Interest Payment Date, Redemption Date, Maturity or Stated Maturity, as the case
may be, if such payment is made or duly provided for on the next succeeding
Business Day, except that, if such Business Day is in the next succeeding
calendar year, such payment shall be made on the immediately preceding Business
Day.

SECTION 114. Computations.

         Unless otherwise specifically provided, the certificate or opinion of
any independent firm of public accountants of recognized standing selected by
the Board of Directors shall be conclusive evidence of the correctness of any
computation made under the provisions of this Indenture. The Company shall
furnish to the Trustee upon its request a copy of any such certificate or
opinion.

SECTION 201. Forms Generally.

         The Securities of each series shall be substantially in the form
attached as Exhibit A, or in such other form or forms as shall be established by

hereto, in each case with such appropriate provisions as are required or
permitted by this Indenture, and may have such letters, numbers or other marks
of identification and such legends or endorsements placed thereon as may be
required to comply with applicable tax laws or the rules of any securities
exchange or Depositary therefor or as may, consistently herewith, be determined
by the officers executing such Securities, as evidenced by their execution
thereof. If the form of Securities of any series is established by action taken
pursuant to a Board Resolution, a copy of an appropriate record of such action
shall be certified by the Secretary or an Assistant Secretary of the Company and
delivered to the Trustee at or prior to the delivery of the Company Order
contemplated by Section 303 with respect to the authentication and delivery of
such Securities.

         The Securities of each series will initially be issued in the form of
one or more Global Securities. Each such Global Security shall represent such of
the Outstanding Securities of such series as shall be specified therein and each
shall provide that it shall represent the aggregate amount of Outstanding
Securities of such series from time to time endorsed thereon and that the
aggregate amounts of Outstanding Securities of such series

                                       14

represented thereby may from time to time be reduced or increased, as
appropriate. The Global Security or Securities evidencing the Securities of a
series (and all Securities issued in exchange therefore) shall bear the legend
indicated in Section 202.

SECTION 202. Form of Legend for Global Securities.

         Every Global Security authenticated and delivered hereunder shall, in
addition to the provisions contained in Exhibit A, bear a legend in

REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC (AND ANY PAYMENT IS MADE TO
CEDE & CO. OR TO SUCH OTHER ENTITY AS IS REQUESTED BY AN AUTHORIZED
REPRESENTATIVE OF DTC), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR
OTHERWISE BY OR TO ANY PERSON IS WRONGFUL INASMUCH AS THE REGISTERED OWNER
HEREOF, CEDE & CO., HAS AN INTEREST HEREIN.

         THIS SECURITY IS A GLOBAL SECURITY WITHIN THE MEANING OF THE INDENTURE
HEREINAFTER REFERRED TO AND IS REGISTERED IN THE NAME OF DTC OR A NOMINEE
THEREOF. THIS SECURITY MAY NOT BE EXCHANGED IN WHOLE OR IN PART FOR A SECURITY
REGISTERED, AND NO TRANSFER OF THIS SECURITY IN WHOLE OR IN PART MAY BE

THE LIMITED CIRCUMSTANCES DESCRIBED IN THE INDENTURE.

<PAGE>
      All Securities of any one series shall be substantially identical except
as to denomination and except as may otherwise be provided herein or in or
pursuant to such Board Resolution and set forth in such Officers' Certificate or
in any such indenture supplemental hereto.

      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.

Section 302. Denominations.

      The Securities of each series shall be in registered form without coupons
and shall be issuable in denominations of $1,000 and any integral multiples
thereof, unless otherwise specified as contemplated by Section 301.

Section 303. Execution, Authentication, Delivery and Dating.

      The Securities shall be executed on behalf of the Company by its Chairman,
President, Chief Executive Officer or any Vice President. 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 executed by the Company to the
Trustee for authentication, together with a Company Order for the authentication
and delivery of such Securities, and the Trustee in accordance with the Company
Order shall authenticate and deliver such Securities.

      Notwithstanding the provisions of the preceding paragraph, if all
Securities of a series are not to be originally issued at one time, it shall not
be necessary to deliver the Company Order otherwise required pursuant to such
preceding paragraph at or prior to the authentication of each Security of such
series if such Company Order is delivered at or prior to the authentication upon
original issuance of the first Security of such series to be issued.

      Each Security shall be dated the date of its authentication.

      No Security shall be entitled to any benefit under this Indenture or be
valid or obligatory for any purpose, unless there appears on such Security a
certificate of authentication substantially in the form provided for herein
executed by the Trustee by the manual signature of one of its authorized
signatories, and such certificate upon any Security shall be conclusive
evidence, and the only evidence, that such Security has been



                                       18
<PAGE>
duly authenticated and delivered hereunder. Notwithstanding the foregoing, if
any Security shall have been authenticated and delivered hereunder but never
issued and sold by the 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.

      Minor typographical and other minor errors in the text of any Security
shall not affect the validity and enforceability of such Security if it has been
duly authenticated and delivered by the Trustee.

      The Company shall execute and the Trustee shall authenticate and deliver
one or more Global Securities with respect to each series of Securities that (i)
shall represent an aggregate amount equal to the aggregate principal amount of
the initially issued Securities of such series, (ii) shall be registered in the
name of the Depositary or the nominee of the Depositary, (iii) shall be
delivered by the Trustee to the Depositary or pursuant to the Depositary's
instruction and (iv) shall bear a legend substantially in the form required in
Section 202.

      The Trustee shall have the right to decline to authenticate and deliver
any Securities under this Section if the Trustee, being advised by counsel,
determines in good faith that such action may not lawfully be taken or if the
Trustee in good faith shall determine that such action would expose the Trustee
to personal liability to existing Holders.

      The Depositary must, at all times while it serves as such Depositary, be a
clearing agency registered under the Exchange Act, and any other applicable
statute or regulation. Neither the Trustee nor any agent shall have any
responsibility for any actions taken or not taken by the Depositary.

Section 304. Temporary Securities.


      Pending the preparation of definitive Securities of any series, the
Company may execute, and upon Company Order the Trustee shall authenticate and
deliver, temporary Securities which are printed, typewritten or otherwise
produced, in any authorized denomination, substantially of the tenor of the
definitive Securities of any series in lieu of which they are issued and with
such appropriate insertions, omissions, substitutions and other variations as
the officers executing such Securities may determine, as evidenced by their
execution of such Securities.

      If temporary Securities of any series are issued, the Company will cause
definitive Securities of such series to be prepared without unreasonable delay.
After the preparation of definitive Securities, the temporary Securities shall
be exchangeable for definitive Securities upon surrender of the temporary
Securities at the office or agency of the Company in a Place of Payment without
charge to the Holder. Upon surrender for cancellation of any one or more
temporary Securities, the Company shall execute and the Trustee shall
authenticate and deliver in exchange therefor a like principal amount of



                                       19
<PAGE>
definitive Securities of the same series of authorized denominations and having
the same Original Issue Date and Stated Maturity and having the same terms as
such temporary Securities. Until so exchanged, the temporary Securities shall in
all respects be entitled to the same benefits under this Indenture as definitive
Securities.

Section 305. Registration, Registration of Transfer and Exchange.

      The Company shall cause to be kept at the Corporate Trust Office a
register (the register maintained in such office or in any other office or
agency of the Company in a Place of Payment being herein sometimes referred to
as the "Security Register") in which, subject to such reasonable regulations as
it may prescribe, the Company shall provide for the registration of Securities
and of transfers and exchanges of Securities. The Trustee is hereby appointed
"Security Registrar" for the purpose of registering Securities and transfers of
Securities as herein provided.

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

      Notwithstanding any other provision of this Section, unless and until it
is exchanged in whole or in part for the individual Securities represented
thereby, a Global Security representing all or a portion of the Securities may
not be transferred except as a whole by the Depositary to a nominee of such
Depositary, or by a nominee of such Depositary to such Depositary or another
nominee of such Depositary, or by such Depositary or any such nominee to a
successor Depositary or nominee of such successor Depositary.

      At the option of the Holder, Securities may be exchanged for other
Securities, of the same series of any authorized denominations, of like tenor
and aggregate principal amount, of the same Original Issue Date and Stated
Maturity and having the same terms, upon surrender of the Securities to be
exchanged at such office or agency. Whenever any Securities are so surrendered
for exchange, the Company shall execute, and the Trustee shall authenticate and
deliver, the Securities which the Holder making the exchange is entitled to
receive.

      If at any time the Depositary notifies the Company that it is unwilling or
unable to continue as Depositary or if at any time the Depositary shall cease to
be a clearing agency registered under the Exchange Act as provided in Section
303, the Company shall appoint a successor Depositary. If a successor Depositary
is not appointed by the Company within 90 days after the Company receives such
notice or becomes aware of such ineligibility, the Company will execute, and the
Trustee, upon receipt of a Company Order for the authentication and delivery of
individual Securities, will authenticate and make available for delivery,
individual Securities in an aggregate principal amount equal



                                       20
<PAGE>
to the principal amount of the Global Security or Securities representing the
Securities in exchange for such Global Security or Securities.

      The Company may at any time and in its sole discretion determine that
individual Securities issued in the form of one or more Global Securities shall
no longer be represented by such Global Security or Securities. In such event
the Company will execute, and the Trustee, upon receipt of a Company Order for
the authentication and delivery of individual Securities, will authenticate and
make available for delivery, individual Securities in an aggregate principal
amount equal to the principal amount of the Global Security or Securities
representing the Securities in exchange for such Global Security or Securities.

      The Depositary may surrender a Global Security in exchange in whole or in
part for individual Securities on such terms as are acceptable to the Company,
the Trustee and such Depositary. Thereupon, the Company shall execute, and the
Trustee shall authenticate and make available for delivery, without service
charge:

      (1) to each Person specified by such Depositary a new individual Security
or Securities of any authorized denomination as requested by such Person in
aggregate principal amount equal to and in exchange for such Person's beneficial
interest in the Global Security; and

      (2) to such Depositary a new Global Security in a denomination equal to
the difference, if any, between the principal amount of the surrendered Global
Security and the aggregate principal amount of individual Securities delivered
to Holders thereof.

      Upon the exchange of a Global Security for individual Securities in an
aggregate principal amount equal to the principal amount of such Global
Security, such Global Security shall be canceled by the Trustee. Individual
Securities issued in exchange for a Global Security pursuant to this Section
shall be registered in such names and in such authorized denominations as the
Depositary for such Global Security, pursuant to instructions from its direct or
indirect participants or otherwise, shall instruct the Trustee. The Trustee
shall make available for delivery such individual Securities to the Persons in
whose names such Securities are so registered.

      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 Security Registrar) be
duly endorsed, or be accompanied by a written instrument of transfer in form
satisfactory to the Company and the Security Registrar duly executed, by the
Holder thereof or his attorney duly authorized in writing.

      No service charge shall be made to a Holder for any registration of
transfer or exchange of Securities, but the Company may require payment of a sum
sufficient to



                                       21
<PAGE>
cover any tax, assessment or other governmental charge that may be imposed in
connection with any registration of transfer or exchange of Securities, other
than exchanges pursuant to Section 304, 906 or 1108 not involving any transfer.

      Neither the Company nor the Trustee shall be required, pursuant to the
provisions of this Section: (i) to issue, register the transfer of or exchange
any Security of any series during a period beginning at the opening of business
15 Business Days before the day of the mailing of a notice of redemption of any
such Securities selected for redemption of Securities pursuant to Article Eleven
and ending at the close of business on the day of such mailing of notice of
redemption; or (ii) to register the transfer of or exchange any Security so
selected for redemption in whole or in part, except, in the case of any Security
to be redeemed in part, any portion thereof that is not redeemed.

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

      If any mutilated Security is surrendered to the Trustee together with such
security or indemnity as may be required by the Company or the Trustee to save
each of them harmless, the Company shall execute and the Trustee shall
authenticate and deliver in exchange therefor a new Security of the same issue
and series, of like tenor and principal amount, having the same Original Issue
Date and Stated Maturity and bearing the same Interest Rate as such mutilated
Security, and bearing a number not contemporaneously outstanding.

      If there shall be delivered to the Company and to the Trustee (i) evidence
to their satisfaction of the destruction, loss or theft of any Security 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 issuing Company shall execute and upon its request the Trustee
shall authenticate and deliver, in lieu of any such destroyed, lost or stolen
Security, a new Security of the same issue and series of like tenor and
principal amount, having the same Original Issue Date and Stated Maturity and
bearing the same Interest Rate as such destroyed, lost or stolen Security, 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 in relation thereto and any other expenses (including
the fees and expenses of the Trustee) connected therewith.

      Every new Security 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



                                       22
<PAGE>
enforceable by anyone, and shall be entitled to all the benefits of this
Indenture equally and proportionately with any and all other Securities duly
issued hereunder.

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

Section 307. Payment of Interest; Interest Rights Preserved.


      Interest on any Security of any series which is payable, and is punctually
paid or duly provided for, on any Interest Payment Date shall be paid to the
Person in whose name that Security (or one or more Predecessor Securities) is
registered at the close of business on the Regular Record Date for such interest
in respect of Securities of such series. The initial payment of interest on any
Security of any series which is issued between a Regular Record Date and the
related Interest Payment Date shall be payable as provided in such Security or
in the Board Resolution pursuant to Section 301 with respect to the related
series of Securities.

      Any interest on any Security which is payable, but is not timely paid or
duly provided for, on any Interest Payment Date for Securities of such series
(herein called "Defaulted Interest"), shall forthwith cease to be payable to the
registered 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 in respect of which
interest is in default (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 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 10 days prior to the date of the proposed payment and not less
than 10 days after the receipt by the Trustee of the notice of the proposed
payment. The Trustee shall promptly notify the Company of such Special Record
Date and, in the name and at the expense of the Company, shall cause notice of
the proposed payment of such Defaulted Interest and the Special Record Date
therefor to be mailed, first class, postage prepaid, to each Holder of a
Security of such series at the address of such Holder as it appears in the
Security Register not less than 10 days prior to such Special Record Date.
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



                                       23
<PAGE>
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 the Securities of the series in
respect of which interest is in default may be listed, and upon such notice as
may be required by such exchange (or by the Trustee if the Securities are not
listed), 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.

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

      None of the Company, the Trustee nor any agent of the Company or the
Trustee will have any responsibility or liability for any aspect of the records
relating to or payments made on account of beneficial ownership interests of a
Global Security or maintaining, supervising or reviewing any records relating to
such beneficial ownership interests.

Section 309. Cancellation.

      All Securities surrendered for payment, redemption, registration of
transfer or exchange shall, if surrendered to any Person other than the Trustee,
be delivered to the Trustee, and any such Securities and Securities surrendered
directly to the Trustee for any such purpose shall be promptly cancelled by it.
The Company may at any time deliver to the Trustee for cancellation any
Securities previously authenticated and delivered hereunder which the Company
may have acquired in any manner whatsoever, and may deliver to the Trustee (or
to any other Person for delivery to the Trustee) for cancellation any Securities
previously authenticated hereunder which the Company has not issued and sold,
and all Securities so delivered shall be promptly cancelled by the Trustee. No
Securities shall be authenticated in lieu of or in exchange for any Securities
cancelled as provided in this Section, except as expressly permitted by this
Indenture. All cancelled Securities held by the Trustee shall be disposed by the
Trustee in accordance with its customary procedures. Acquisition by the Company
of any Security shall not operate as



                                       24
<PAGE>
a redemption or satisfaction of the indebtedness represented by such Security
unless and until the same is delivered to the Trustee for cancellation.

Section 310. Computation of Interest.

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

Section 311. CUSIP Numbers.

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

                           SATISFACTION AND DISCHARGE

Section 401. Satisfaction and Discharge of Indenture.

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

      (1) either

            (A) all Securities theretofore authenticated and delivered (other
      than (i) Securities which have been destroyed, lost or stolen and which
      have been replaced or paid as provided in Section 306 and (ii) Securities
      for whose payment money has theretofore been deposited in trust or
      segregated and held in trust by the Company and thereafter repaid to the
      Company or discharged from such trust, as provided in Section 1003) have
      been delivered to the Trustee for cancellation; or

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

                  (i) have become due and payable, or



                                       25
<PAGE>
                  (ii) will become due and payable at their Stated Maturity
            within one year of the date of deposit, or

                  (iii) are to be called for redemption within one year under
            arrangements satisfactory to the Trustee for the giving of notice of
            redemption by the Trustee in the name, and at the expense, of the
            Company,

and the Company, in the case of (i), (ii) or (iii) above, has deposited or
caused to be deposited with the Trustee as trust funds: (A) money in an amount;
(B) Government Obligations 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, money in an amount; or
(C) a combination thereof, in each case sufficient, in the opinion of a
nationally recognized firm of independent public accountants expressed in a
written certification thereof delivered to the Trustee of such series (but such
opinion need only be delivered if Government Obligations have been so
deposited), to pay and discharge, and which shall be applied by the Trustee, to
pay and discharge the entire indebtedness on such Securities not theretofore
delivered to the Trustee for cancellation, for principal (and premium, if any)
and interest to the date of such deposit (in the case of Securities which have
become due and payable) or to the Stated Maturity or Redemption Date, as the
case may be;

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

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

      The Company shall pay and indemnify the Trustee against any tax, fee or
other charge imposed on or assessed against the Government Obligations deposited
pursuant to Section 401 or the principal and interest received in respect
thereof other than any such tax, fee or other charge which by law is for the
account of the Holders of Outstanding Securities.

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

Section 402. Application of Trust Money.

      Subject to the provisions of the last paragraph of Section 1003, all money
and Government Obligations deposited with the Trustee pursuant to Section 401
and all proceeds of such Government Obligations and the interest thereon, shall
be held in trust



                                       26
<PAGE>
and applied by it, in accordance with the provisions of the Securities and this
Indenture, to the payment, either directly or through any Paying Agent
(including the Company acting as its own Paying Agent) as the Trustee may
determine, to the Persons entitled thereto, of the principal and any premium and
interest for whose payment such money and Government Obligations have been
deposited with the Trustee.

                                  ARTICLE FIVE

                                    REMEDIES

Section 501. Events of Default.

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

      (1) default in the payment of any interest upon any Security of that
series when it becomes due and payable, and such default continues for a period
of 30 days; or

      (2) default in the payment of the principal of or premium, if any, on any
Security of that series at its Maturity; or

      (3) default in the performance, or breach, of any covenant or warranty of
the Company in this Indenture (other than a covenant or warranty a default in
the performance of which or the breach of which is specifically dealt with
elsewhere in this Section), and continuance of such default or breach for a
period of 90 days after there has been given, by registered or certified mail,
to the Company by the Trustee or to the Company and the Trustee by the Holders
of at least 25% in aggregate principal amount of the Outstanding Securities of
that series a written notice specifying such default or breach and requiring it
to be remedied and stating that such notice is a "Notice of Default" hereunder;
or

      (4) the entry of a decree or order by a court having jurisdiction in the
premises adjudging the Company bankrupt or insolvent, or approving as properly
filed a petition seeking reorganization, arrangement, adjustment or composition
of or in respect of the Company under any applicable Federal or State
bankruptcy, insolvency, reorganization or other similar law, or appointing a
receiver, liquidator, assignee, trustee, sequestrator (or other similar
official) of the Company or of any substantial part of its property or ordering
the winding up or liquidation of its affairs, and the continuance of any such
decree or order unstayed and in effect for a period of 90 consecutive days; or

      (5) the institution by the Company of proceedings to be adjudicated
bankrupt or insolvent, or the consent by it to the institution of bankruptcy or
insolvency proceedings against it, or the filing by it of a petition or answer
of consent seeking reorganization or relief under any applicable Federal or
State bankruptcy, insolvency, reorganization or other similar law, or the
consent by it to the filing of any such petition or to the



                                       27
<PAGE>
appointment of a receiver, liquidator assignee, trustee, sequestrator (or other
similar official) of the Company or of any substantial part of its property, or
the making by it of an assignment for the benefit of creditors, or the admission
by it in writing of its inability to pay its debts generally as they become due
and its willingness to be adjudicated bankrupt, or the taking of corporate
action by the Company in furtherance of any such action; or

      (6) any other Event of Default specified with respect to Securities of
that series as contemplated in Section 301.

Section 502. Acceleration of Maturity; Rescission and Annulment.

      If an Event of Default (other than an Event of Default specified in
Section 501(4) or 501(5)) with respect to Securities of any series at the time
Outstanding occurs and is continuing, then in every such case the Trustee or the
Holders of not less than 25% in aggregate principal amount of the Outstanding
Securities of that series may declare the principal amount (or, if the
Securities of that series are Original Issue Discount Securities, such portion
of the principal amount as may be specified in the terms of that series) of all
of the Securities of that series to be due and payable immediately, by a notice
in writing to the Company (and to the Trustee if given by Holders), and upon any
such declaration such principal amount (or specified amount) shall become
immediately due and payable. If an Event of Default specified in Section 501(4)
or 501(5) with respect to Securities of a series at the time Outstanding occurs,
the principal amount of all the Securities of such series (or specified amount)
shall automatically, and without any declaration or other action on the part of
the Trustee or any Holder, become immediately due and payable.

      At any time after such a declaration of acceleration with respect to
Securities of any series has been made and before a judgment or decree for
payment of the money due has been obtained by the Trustee as hereinafter in this
Article provided, the Holders of not less than a majority in aggregate principal
amount of the Outstanding Securities of that series, by written notice to the
Company and the Trustee, may rescind and annul such declaration and its
consequences if:

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

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

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

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



                                       28
<PAGE>
            (D) all sums paid or advanced by the Trustee hereunder and the
      compensation, reasonable disbursements, advances and expenses of the
      Trustee, its agents and counsel; and

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

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

Section 503. Collection of Indebtedness and Suits for Enforcement by Trustee.

      The Company covenants that if:

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

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

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

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

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

Section 504. Trustee May File Proofs of Claim.

      In case of any judicial proceeding relative to the Company (or any other
obligor upon the Securities), its property or its creditors:

      (a) the Trustee shall be entitled and empowered, by intervention in such
proceeding or otherwise,

            (i) to take any and all actions authorized under the Trust Indenture
      Act in order to have claims of the Holders and the Trustee allowed in any
      such proceeding, and

            (ii) in particular, the Trustee shall be authorized to collect and
      receive any moneys or other property payable or deliverable on any such
      claims and to distribute the same in accordance with Section 506; and

      (b) any custodian, receiver, assignee, trustee, liquidator, sequestrator
or other similar official in any such judicial proceeding is hereby authorized
by each Holder to make such payments to the Trustee for distribution in
accordance with Section 506, and, in the event that the Trustee shall consent to
the making of such payments directly to the Holders, to pay to the Trustee any
amount due it for the compensation, reasonable disbursements, advances and
expenses of the Trustee, its agents and counsel, and any other amounts due the
Trustee under Section 607.

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

Section 505. Trustee May Enforce Claims Without Possession of Securities.

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

Section 506. Application of Money Collected.

      Any money or property collected or to be applied by the Trustee with
respect to a series of Securities pursuant to this Article shall be applied in
the following order, at the date or dates fixed by the Trustee and, in case of
the distribution of such money or



                                       30
<PAGE>
property on account of principal or premium, if any, or interest, upon
presentation of the Securities and the notation thereon of the payment if only
partially paid and upon surrender thereof if fully paid:

      FIRST: To the payment of all amounts due the Trustee and any predecessor
Trustee under Section 607;

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

      THIRD: To the payment of the remainder, if any, to the Company, its
successors or assigns or to whomsoever may be lawfully entitled to receive the
same or as a court of competent jurisdiction may direct.

Section 507. Limitation on Suits.

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

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

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

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

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

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

it being understood and intended that no one or more of such Holders shall have
any right in any manner whatever by virtue of, or by availing of, any provision
of this Indenture to affect, disturb or prejudice the rights of any other of
such Holders (it being understood that the Trustee does not have an affirmative
duty to ascertain whether or not such actions or forbearances are unduly
prejudicial to such Holders), or to obtain or to seek to obtain priority or
preference over any other of such Holders or to enforce any right under this



                                       31
<PAGE>
Indenture, except in the manner herein provided and for the equal and ratable
benefit of all of such Holders.

Section 508. Unconditional Right of Holders to Receive Principal, Premium and
Interest.

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

Section 509. Restoration of Rights and Remedies.

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

Section 510. Rights and Remedies Cumulative.

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

Section 511. Delay or Omission Not Waiver.

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

Section 512. Control by Holders.

      The Holders of a majority in aggregate principal amount of the Outstanding
Securities of any series shall have the right to direct the time, method and
place of conducting any proceeding for any remedy available to the Trustee, or
exercising any



                                       32
<PAGE>
trust or power conferred on the Trustee, with respect to the Securities of such
series, provided that:

      (1) such direction shall not be in conflict with any rule of law or with
this Indenture, involve the Trustee in personal liability or be unduly
prejudicial to the Holders of the Securities not joining in the action; and

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

Section 513. Waiver of Past Defaults.

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

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

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

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

Section 514. Undertaking for Costs.

      All parties to this Indenture agree, and each holder of any Security by
his acceptance thereof shall be deemed to have agreed, that any court may in its
discretion require, in any suit for the enforcement of any right or remedy under
this Indenture, or in any suit against the Trustee for any action taken,
suffered or omitted by it as Trustee, any party litigant in such suit to file an
undertaking to pay the costs of such suit, and that court may in its discretion
assess reasonable costs, including reasonable attorneys' fees, against any such
party litigant in such suit, having due regard to the merits and good faith of
the claims or defenses made by such party litigant, in the manner and to the
extent provided in the Trust Indenture Act; provided, that neither this Section
nor the Trust Indenture Act shall be deemed to authorize any court to require
such an undertaking or to make such an assessment in any suit instituted by the
Company or by the Trustee, to any suit instituted by any Holder, or group of
Holders, holding in the aggregate more than 10% in principal amount of the
Outstanding Securities of any series, or any suit instituted by any Holder for
the enforcement of the payment of the principal of (or premium, if any) or
interest on any Security on or after the respective Stated Maturities expressed
in such Security (or in the case of redemption, on the Redemption Date).

Section 515. Waiver of Usury, Stay or Extension Laws.

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

                                   ARTICLE SIX

                                   THE TRUSTEE

Section 601. Certain Duties and Responsibilities.


      (a) Except during the continuance of an Event of Default,

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

            (ii) in the absence of bad faith on its part, the Trustee may
      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 of mathematical calculations or other
      facts stated therein).

      (b) In case 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 person would exercise or use under the circumstances in the conduct of
his or her own affairs.

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

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

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



                                       34
<PAGE>
            (iii) the Trustee shall not be liable with respect to any action
      taken or omitted to be taken by it in good faith in accordance with the
      direction of the Holders of a majority in principal amount of the
      Outstanding Securities of any series, determined as provided in Sections
      101, 104 and 512, relating to the time, method and place of conducting any
      proceeding for any remedy available to the Trustee, or exercising any
      trust or power conferred upon the Trustee, under this Indenture with
      respect to the Securities of such series; and

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

Indenture relating to the conduct or affecting the liability of or affording
protection to the Trustee shall be subject to the provisions of this Section.

Section 602. Notice of Defaults.

      If a default occurs hereunder with respect to the Securities of a series,
the Trustee within 90 days of such default shall give the Holders notice of such
default as and to the extent provided by the Trust Indenture Act; provided,
however, that in the case of any default of the character specified in Section
501(3) with respect to such Securities, no such notice to Holders shall be given
until at least 30 days after the occurrence thereof; and provided, further, that

501(1) and (2)), if and so long as the board of directors, the executive
committee or a trust committee of directors or Responsible Officers of the
Trustee in good faith determine that the withholding of the notice is in the
interest of the Holders of such Securities. For the purpose of this Section, the
term "default" means any event which is, or after notice or lapse of time or
both would become, an Event of Default with respect to the Securities of a
series.

rely upon an Officers' Certificate and may at its discretion secure such further
evidence deemed necessary or advisable, but shall in no case be bound to secure
the same;

shall survive the Trustee's resignation or removal and final payment of the
Securities;

      (8) the Trustee is not required to give any bond or surety with respect to
the performance of its duties or the exercise of its powers under this
Indenture;

      (9) the Trustee shall not be deemed to have actual knowledge of any
"default" or Event of Default hereunder except (i) during any period it is

SECTION 607. Compensation and Reimbursement.

         The Company agrees:

         (1) to pay to the Trustee from time to time compensation for all
services rendered by it hereunder (which compensation shall not be limited by

trust);

         (3) to indemnify each of the Trustee or any predecessor Trustee and
their agents for, and to hold them harmless against, any and all loss, damage,

connection with the acceptance or administration of the trust or trusts
hereunder, including the costs and expenses of defending itself against any
claim (whether asserted by the Company, or any Holder or any other Person) or
liability in connection with the exercise or performance of any of its powers or
duties hereunder, or in connection with enforcing the provisions of this
Section, except to the extent that such loss, damage, claim, liability or
expense is due to its own negligence or bad faith; and

         (4) without limiting any rights available to the Trustee under

connection with an Event of Default specified in Section 501(4) or Section
501(5), the expenses (including the reasonable charges and expenses of its
counsel) and the compensation for the services are intended to constitute
expenses of administration under any applicable federal or state bankruptcy,
insolvency or other similar law.

SECTION 608. Disqualification; Conflicting Interests.

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


                                       38

the District of Columbia, (ii) be authorized under such laws to exercise
corporate trust powers, (iii) have a combined capital and surplus of at least
$50,000,000, and (iv) be subject to supervision or examination by Federal or
State authority. If such corporation files reports of condition at least
annually, pursuant to law or to the requirements of said supervising or
examining authority, then for the purposes of this Section, the combined capital
and surplus of such corporation shall be deemed to be its combined capital and
surplus as set forth in its most recent report of condition so filed. If the
Trustee has or shall acquire a conflicting interest within the meaning of the
Trust Indenture Act, the Trustee shall either eliminate such interest or resign,
to the extent and in the manner provided by, and subject to the provisions of,
the Trust Indenture Act and this Indenture. If at any time the Trustee shall
cease to be eligible in accordance with the provisions of this Section, it shall
resign immediately in the manner and with the effect hereinafter specified in
this Article Six. Neither the Company nor any Person directly or indirectly
controlling, controlled by or under common control with the Company shall serve
as Trustee for the Securities of any series issued hereunder.

SECTION 610. Resignation and Removal; Appointment of Successor.

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

         The Trustee may resign as Trustee at any time with respect to the
Securities of one or more series by giving written notice thereof to the
Company. If the instrument of acceptance by a successor Trustee required by
Section 611 shall not have been delivered to the resigning Trustee within 30
days after the giving of such notice of resignation, the resigning Trustee may,
at the expense of the Company, petition any court of competent jurisdiction for
the appointment of a successor Trustee with respect to the Securities of such
series.

         The Trustee may be removed as Trustee hereunder 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.

         If at any time an instrument of acceptance by a successor Trustee
required by Section 611 shall not have been delivered to the Trustee within 30
days after the date a notice of removal is delivered to the Trustee, the Trustee
being removed may, at the expense of the Company, petition any court of
competent jurisdiction for the appointment of a successor Trustee with respect
to the Securities of such series.

         If at any time:


                                       39
<PAGE>
         (1) the Trustee shall fail to comply with Section 608 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 609 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, (A) the Company by a Board Resolution may remove the
Trustee, or (B) subject to Section 514, any Holder who has been a bona fide
Holder of a Security for at least six months may, on behalf of himself and all
others similarly situated, petition any court of competent jurisdiction for the
removal of the Trustee and the appointment of a successor Trustee or Trustees.

         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 and shall comply with the applicable
requirements of Section 611. If, within one year after such resignation, removal
or incapability, or the occurrence of such vacancy, a successor Trustee with
respect to the Securities of any series shall be appointed by Act of the Holders
of a majority in principal amount of the Outstanding Securities of such series
delivered to the 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 611, 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 611, any
Holder who has been a bona fide Holder of a Security for at least six months
may, subject to Section 514, 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.

         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 the
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 611. Acceptance of Appointment by Successor.

         (a) In the 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 and
each successor Trustee with respect to the Securities of one or more series
shall execute and deliver an indenture supplemental hereto wherein each
successor trustee shall accept such appointment and which (1) shall contain such
provisions as shall be necessary or desirable to transfer and confirm to, and to
vest in, each successor Trustee all the rights, powers, trusts and duties of the
retiring Trustee with respect to the Securities of that or those series to which
the appointment of such successor Trustee relates, (2) if the retiring Trustee
is not retiring with respect to all Securities, shall contain such provisions as
shall be deemed necessary or desirable to confirm that all the rights, powers,
trusts and duties of the retiring Trustee with respect to the Securities of that
or those series as to which the retiring Trustee is not retiring shall continue
to be vested in the retiring Trustee, and (3) shall add to or change any of the
provisions of this Indenture as shall be necessary to provide for or facilitate
the administration of the trusts hereunder by more than one Trustee, it being
understood that nothing herein or in such supplemental indenture shall
constitute such Trustees co-trustees of the same trust and that each such
Trustee shall be trustee of a trust or trusts hereunder separate and apart from
any trust or trusts hereunder administered by any other such Trustee and upon
the execution and delivery of such supplemental indenture the resignation or
removal of the retiring Trustee shall become effective to the extent provided
therein and each such successor Trustee, without any further act, deed or
conveyance, shall become vested with all the rights, powers, trusts, and duties
of the retiring Trustee with respect to the Securities of that or those series
to which the appointment of such successor Trustee relates; but, on request of
the Company or any successor Trustee, such retiring Trustee shall duly assign,
transfer and deliver to such successor Trustee all property and money held by
such retiring Trustee hereunder with respect to the Securities of that or those
series to which the appointment of such successor Trustee relates.

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


                                       41
<PAGE>
         (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 612. Merger, Conversion, Consolidation or Succession to Business.

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

SECTION 613. Preferential Collection of Claims Against Company.

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

SECTION 614. Appointment of Authenticating Agent.

         The Trustee may appoint an Authenticating Agent or Agents with respect
to one or more series of Securities which shall be authorized to act on behalf
of the Trustee to authenticate Securities of such series issued upon original
issue and upon exchange, registration of transfer or partial redemption thereof
or pursuant to Section 306, and Securities so authenticated shall be entitled to
the benefits of this Indenture and shall be valid and obligatory for all
purposes as if authenticated by the Trustee hereunder. Wherever reference is
made in this Indenture to the authentication and delivery of Securities by the
Trustee or the Trustee's certificate of authentication, such reference shall be
deemed to include authentication and delivery on behalf of the Trustee by an
Authenticating Agent and a certificate of authentication executed on behalf of
the Trustee by an Authenticating Agent. Each Authenticating Agent 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,
Territory or the District of Columbia, authorized under such laws to act as
Authenticating Agent, having a combined capital and surplus of not less than
$50,000,000 and subject to supervision or examination by Federal or State
authority. If such Authenticating Agent files 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
filed.


                                       42
<PAGE>
         If at any time an Authenticating Agent shall cease to be eligible in
accordance with the provisions of this Section, such Authenticating Agent shall
resign immediately in the manner and with the effect specified in this Section.

         Any corporation into which an Authenticating Agent may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which such Authenticating Agent
shall be a party, or any corporation succeeding to all or substantially all of
the corporate trust business of an Authenticating Agent, shall be the successor
Authenticating Agent hereunder, 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 any time terminate
the agency of an Authenticating Agent by giving written notice thereof to such
Authenticating Agent and to the Company. Upon receiving such a notice of
resignation or upon such a termination, or in case at any time such
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, the Trustee may appoint a successor Authenticating
Agent which shall be acceptable to the Company and shall give notice of such
appointment in the manner provided in Section 106 to all Holders of Securities
of the series with respect to which such Authenticating Agent will serve. Any
successor Authenticating Agent upon acceptance of its appointment hereunder
shall become vested with all the rights, powers and duties of its predecessor
hereunder, with like effect as if originally named as an Authenticating Agent.

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

         The Company agrees to pay to each Authenticating Agent from time to
time compensation for its services under this Section as agreed to in writing
between the parties.

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


                                       43

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

         The rights of Holders to communicate with other Holders with respect to
their rights under this Indenture or under the Securities, and the corresponding

Indenture Act.

         Every Holder of Securities, by receiving and holding the same, agrees

         With the consent of the Holders of not less than a majority in

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

that no such supplemental indenture shall, without the consent of the Holder of
each Outstanding Security affected thereby:

         (1) change the Stated Maturity of the principal of, or any installment
of interest payable on, any Outstanding Security, or reduce the principal amount

Indenture of the Holders of Securities of any other series.

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

SECTION 903. Execution of Supplemental Indentures.

         In executing, or accepting the additional trusts created by, any
supplemental indenture permitted by this Article or the modifications thereby of
the trusts created by this Indenture, the Trustee shall be entitled to receive,

Officers' Certificate and an Opinion of Counsel stating that the execution of
such supplemental indenture is authorized or permitted by this Indenture, and

affects the Trustee's own rights, duties, protections, privileges, indemnities,
liabilities or immunities under this Indenture or otherwise.

SECTION 904. Effect of Supplemental Indentures.

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

                                   ARTICLE TEN

                                    COVENANTS

SECTION 1001. 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, premium, if
any, and interest on the Securities of that series in accordance with the terms
of such Securities and this Indenture.

      Unless otherwise specified as contemplated by Section 301, the Company
shall pay interest on overdue amounts at the rate set forth in the first
paragraph of the Securities, and it shall pay interest on overdue interest at
the same rate (to the extent that the payment of such interest shall be legally
enforceable), which interest on overdue interest shall accrue from the date such
amounts became overdue.

SECTION 1002. Maintenance of Office or Agency.

      The Company will maintain in the Borough of Manhattan, The City of New
York and each other Place of Payment for any series, an office or agency where
Securities of that series may be presented or surrendered for payment, and an
office or agency where Securities may be surrendered for registration of
transfer or exchange and where notices and demands to or upon the Company in
respect of the Securities and this Indenture may be served. The Company
initially appoints the Trustee, acting through its Corporate Trust Office, as
its agent for said purposes. The Company will give prompt written notice to the
Trustee of the location, and any change in the location, of any such office or
agency. If at any time the Company shall fail to maintain any such required
office or agency or shall fail to furnish the Trustee with the address thereof,
such presentations, surrenders, notices and demands may be made or served at the
Corporate Trust Office, and the Company hereby appoints the Trustee as its agent
to receive all such presentations, surrenders, notices and demands.


                                       50
<PAGE>
      The Company may also from time to time designate one or more other offices
or agencies where the Securities may be presented or surrendered for any or all
such purposes and may from time to time rescind such designations; provided,
however, that no such designation or rescission shall in any manner relieve the
Company of its obligation to maintain an office or agency in the Borough of
Manhattan, The City of New York and each other Place of Payment for Securities
of any series for such purposes. The Company will give prompt written notice to
the Trustee of any such designation or rescission and of any change in the
location of any such other office or agency.

SECTION 1003. 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 or 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 sufficient to pay the principal, premium, if any, and any interest
so becoming due until such sums shall be paid to such Persons or otherwise
disposed of as herein provided and will promptly notify the Trustee of its
action or failure so to act.

      Whenever the Company shall have one or more Paying Agents, it will, prior
to each due date of the principal of or interest on any Securities, 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 as provided by the Trust Indenture
Act, and (unless such Paying Agent is the Trustee) the Company will promptly
notify the Trustee of its action or failure so to act.

      The Company will cause each Paying Agent other than the Trustee to execute
and deliver to the Trustee an instrument in which such Paying Agent shall agree
with the Trustee, subject to the provisions of this Section, that such Paying
Agent will (1) comply with the provisions of the Trust Indenture Act applicable
to it as a Paying Agent, (2) give the Trustee notice of any default by the
Company (or any other obligor upon the Securities) in the making of any payment
of principal (and premium, if any) or interest, and (3) at any time during the
continuance of any such default, upon the written request of the Trustee,
forthwith pay to the Trustee all sums so held in trust by such Paying Agent.

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

      Any money or U.S. Government Obligation (including the proceeds thereof
and the interest thereon) 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


                                       51
<PAGE>
Security and remaining unclaimed for two years after such principal, premium, if
any, or interest has become due and payable shall be paid to the Company at its
option on Company Request (unless otherwise required by mandatory provision of
applicable escheat or abandoned or unclaimed property law) or (if then held by
the Company) shall (unless otherwise required by mandatory provision of
applicable escheat or abandoned or unclaimed property law) be discharged from
such trust; and the Holder of such Security shall thereafter, as an unsecured
general creditor, look only to the 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.

SECTION 1004. Statement by Officers as to Default.

      The Company will deliver to the Trustee, within 120 days after the end of
each fiscal year of the Company ending after the date hereof, an Officers'
Certificate covering the preceding fiscal year, stating whether or not, to the
best knowledge of the signers thereof, the Company is in default in the
performance and observance of any of the terms, provisions and conditions of
this Indenture (without regard to any period of grace or requirement of notice
provided hereunder) and, if the Company shall be in default, specifying all such
defaults and the nature and status thereof of which they may have knowledge.

SECTION 1005. Existence.

      Subject to Article Eight, the Company will do or cause to be done all
things necessary to preserve and keep in full force and effect its legal
existence, rights (charter and statutory) and franchises; provided, however,
that the Company shall not be required to preserve any such right or franchise
if the Board of Directors shall determine that the preservation thereof is no
longer desirable in the conduct of the business of the Company and that the loss
thereof is not disadvantageous in any material respect to the Holders.

SECTION 1006. Payment of Taxes.

      The Company will pay or discharge or cause to be paid or discharged,
before the same shall become delinquent, all taxes, assessments and governmental
charges levied or imposed upon the Company or any Restricted Subsidiary or upon
the income, profits or property of the Company or any Restricted Subsidiary, and
lawful claims for labor, materials and supplies, which, if unpaid, might by law
become a Lien upon the property of the Company or any Restricted Subsidiary;
provided, however, that the Company shall not be required to pay or discharge or
cause to be paid or discharged any such tax, assessment or governmental charge
whose amount, applicability or validity is being


                                       52
<PAGE>
contested in good faith by appropriate proceedings or where the failure to
effect such payment is not adverse in any material respect to the Holders of the
Securities.

SECTION 1007. Limitation on Liens.

      The Company will not, nor will it permit any Restricted Subsidiary,
directly or indirectly, to, create, issue, assume, incur, or guarantee or become
liable with respect to indebtedness for money borrowed if such indebtedness is
secured by a Lien on any present or future common stock of any Restricted
Subsidiary (whether such shares of common stock are now owned or hereafter
acquired) without in any such case making or causing to be made effective a
provision (and the Company covenants that in any such case it shall make or
cause to be made effective such provision) whereby the Securities, will be
secured equally and ratably with, or prior to, such indebtedness or guarantee;
it being understood that in such event the Company may also so secure any other
such indebtedness of the Company or such Restricted Subsidiary entitled thereto,
subject to any applicable priority of payment.

SECTION 1008. Waiver of Certain Covenants.

      The Company may omit in any particular instance to comply with any term,
provision, covenant or condition set forth in any covenant provided pursuant to
Section 901(5) for the benefit of the Holders or in any of Sections 1006 and
1007, with respect to the Securities of any series if before or after the time
for such compliance the Holders of at least a majority in principal amount of
the Outstanding Securities of such series shall, by Act of such Holders, either
waive such compliance in such instance or generally waive compliance with such
term, provision or condition, but no such waiver shall extend to or affect such
term, provision or condition except to the extent so expressly waived, and,
until such waiver shall become effective, the obligations of the Company and the
duties of the Trustee in respect of any such term, provision or condition shall
remain in full force and effect.

SECTION 1009. Calculation of Original Issue Discount.

      The Company shall file with the Trustee promptly at the end of each
calendar year (i) a written notice specifying the amount of original issue
discount (including daily rates and accrual periods) accrued on Outstanding
Securities as of the end of such year and (ii) such other specific information
relating to such original issue discount as may then be relevant under the
Internal Revenue Code of 1986, as amended from time to time.

                                 ARTICLE ELEVEN

                            REDEMPTION OF SECURITIES

SECTION 1101. Company's Right of Redemption.

      Unless otherwise specified as contemplated by Section 301 with respect to
the Securities of a particular series, and notwithstanding any additional
redemption rights that may be so specified, the Company may, at its option,
redeem the Securities of any series


                                       53
<PAGE>
after their date of issuance in whole or in part at any time and from time to
time, subject to the provisions of this Section 1101 and the other provisions of
this Article Eleven. Unless otherwise specified as contemplated by Section 301
with respect to the Securities of a particular series, the redemption price for
any Security so redeemed shall be equal to 100% of the principal amount of such
Securities then Outstanding plus accrued and unpaid interest up to, but
excluding, the date fixed for redemption; provided, however, that installments
of accrued and unpaid interest whose Stated Maturity is on or prior to the
Redemption Date will be payable to the Holders of such Securities, or one or
more Predecessor Securities, registered as such at the close of business on the
relevant Regular Record Dates according to their terms and the provisions of
Section 307.

SECTION 1102. Applicability of Article.

      Redemption of Securities, as permitted or required by any form of Security
issued pursuant to this Indenture or the documentation providing therefor, shall
be made in accordance with such form of Security or documentation and this
Article Eleven; provided, however, that if any provision of any such form of
Security or documentation shall conflict with any provision of this Article, the
provision of such form of Security or documentation shall govern. Except as
otherwise set forth in the form of Security for such series or such
documentation, each Security shall be subject to partial redemption only in the
amount of $1,000 or integral multiples of $1,000.

SECTION 1103. Election to Redeem; Notice to Trustee.

      The election of the Company to redeem any Securities shall be evidenced by
or pursuant to a Board Resolution. In case of any redemption at the election of
the Company of the Securities of a series, the Company shall, at least 45 days
but not more than 60 days prior to the Redemption Date fixed by the Company
(unless a shorter notice shall be satisfactory to the Trustee), notify the
Trustee of such Redemption Date, of the principal amount of Securities to be
redeemed and, if applicable, of the tenor of the Securities to be redeemed. In
the case of any redemption of Securities (a) prior to the expiration of any
restriction on such redemption provided in the terms of such Securities or (b)
pursuant to an election of the Company which is subject to a condition specified
in the terms of such Securities, the Company shall furnish the Trustee with an
Officers' Certificate and an Opinion of Counsel evidencing compliance with such
restriction or condition.

SECTION 1104. Selection by Trustee of Securities to Be Redeemed.

      If less than all the Securities are to be redeemed (unless such redemption
affects only a single Security), the particular Securities to be redeemed shall
be selected not more than 45 days prior to the Redemption Date by the Trustee,
from the Outstanding Securities not previously called for redemption, by such
method as the Trustee in its sole discretion shall deem fair and appropriate and
which may provide for the selection for redemption of a portion of the principal
amount of any Security, provided that the unredeemed portion of the principal
amount of any Security shall be in an authorized denomination (which shall not
be less than the minimum authorized denomination) for


                                       54
<PAGE>
such Security. If less than all the Securities and of a specified tenor are to
be redeemed (unless such redemption affects only a single Security), the
particular Securities to be redeemed shall be selected not more than 45 days
prior to the Redemption Date by the Trustee, from the Outstanding Securities and
specified tenor not previously called for redemption in accordance with the
preceding sentence.

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

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

      For all purposes of this Indenture, unless the context otherwise requires,
all provisions relating to the redemption of Securities shall relate, in the
case of any Securities redeemed or to be redeemed only in part, to the portion
of the principal amount of such Securities which has been or is to be redeemed.
If the Company shall so direct, Securities registered in the name of the
Company, any Affiliate or any Subsidiary thereof shall not be included in the
Securities selected for redemption.

SECTION 1105. Notice of Redemption.

      Notice of redemption shall be given by first-class mail, postage prepaid,
mailed not less than 30 nor more than 60 days prior to the Redemption Date, to
each Holder of Securities to be redeemed, at its address appearing in the
Security Register. Unless the Company defaults in payment of the Redemption
Price, on and after the Redemption Date, interest shall cease to accrue on the
Securities.

      All notices of redemption shall state:

      (1) the Redemption Date;

      (2) the Redemption Price, or if not then ascertainable, the manner of
calculation thereof;

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

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


                                       55
<PAGE>
      (5) the place or places where each such Security is to be surrendered for
payment of the Redemption Price; and

      (6) the CUSIP numbers, if any.

      Notice of redemption of Securities to be redeemed at the election of the
Company shall be given by the Company or, at the Company's request, by the
Trustee in the name and at the expense of the Company and shall be irrevocable.
The notice if 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, a failure to give such notice by mail or any defect in the notice
to the Holder of any Security designated for redemption as a whole or in part
shall not affect the validity of the proceedings for the redemption of any other
Security.

SECTION 1106. Deposit of Redemption Price.

      Prior to 10:00 a.m. New York City time on any Redemption Date, the Company
shall deposit with the Trustee or with a Paying Agent (or, if the Company is
acting as its own Paying Agent, segregate and hold in trust as provided in
Section 1003) an amount of money sufficient to pay the Redemption Price of, and
(except if the Redemption Date shall be an Interest Payment Date) accrued
interest on, all the Securities which are to be redeemed on that date.

SECTION 1107. Securities Payable on Redemption Date.

      Notice of redemption having been given pursuant to Section 1105, the
Securities to be so 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 or accrue any 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 any accrued but unpaid interest to, but excluding, the Redemption
Date; provided, however, that installments of accrued and unpaid interest whose
Stated Maturity is on or prior to the Redemption Date will be payable to the
Holders of such Securities, or one or more Predecessor Securities, registered as
such at the close of business on the relevant 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 any premium shall, until paid, bear
interest from the Redemption Date at the rate prescribed therefor in the
Security.

SECTION 1108. Securities Redeemed in Part.

      Any Security which is to be redeemed only in part shall be surrendered at
a Place of Payment therefor (with, if the 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 his attorney
duly authorized in writing),


                                       56
<PAGE>
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 like tenor, of any authorized denomination as requested by such Holder, in
aggregate principal amount equal to and in exchange for the unredeemed portion
of the principal of the Security so surrendered.

                                 ARTICLE TWELVE

                       DEFEASANCE AND COVENANT DEFEASANCE

SECTION 1201. Company's Option to Effect Defeasance or Covenant Defeasance.

      The Company may elect, at its option at any time, to have Section 1202 or
Section 1203 applied to any Securities upon compliance with the conditions set
forth below in this Article. Any such election shall be evidenced by a Board
Resolution.

SECTION 1202. Defeasance and Discharge.

      Upon the Company's exercise of its option (if any) to have this Section
applied to any Securities, the Company shall be deemed to have been discharged
from its obligations with respect to such Securities as provided in this Section
on and after the date the conditions set forth in Section 1204 are satisfied
(hereinafter called "Defeasance"). For this purpose, such Defeasance means that
the Company shall be deemed to have paid and discharged the entire indebtedness
represented by such Securities and to have satisfied all its other obligations
under such Securities and this Indenture insofar as such Securities are
concerned (and the Trustee, at the expense of the Company and upon Company
Request, shall execute proper instruments acknowledging the same), subject to
the following, which shall survive until otherwise terminated or discharged
hereunder: (1) the Company's obligations with respect to such Securities under
Sections 304, 305, 306, 1002 and 1003; (2) the rights, powers, trusts, duties
and immunities of the Trustee hereunder, including but not limited to those
enumerated under Sections 601, 603 and 607; and (3) this Article. Subject to
compliance with this Article, the Company may exercise its option (if any) to
have this Section applied to any Securities notwithstanding the prior exercise
of its option (if any) to have Section 1203 applied to such Securities.

SECTION 1203. Covenant Defeasance.

      Upon the Company's exercise of its option (if any) to have this Section
applied to any Securities (1) the Company shall be released from its obligations
under Sections 801, Sections 1006 and 1007, and any covenants provided pursuant
to 901(5) for the benefit of the Holders of such Securities; and (2) the
occurrence of any event specified in Sections 501(3) (with respect to any of
Section 801, Sections 1006 and 1007, and any such covenants provided pursuant to
Section 901(5)) shall be deemed not to be or result in an Event of Default, in
each case with respect to such Securities as provided in this Section on and
after the date the conditions set forth in Section 1204 are satisfied
(hereinafter called "Covenant Defeasance"). For this purpose, such Covenant
Defeasance means that,


                                       57
<PAGE>
with respect to such Securities, 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 specified Section (to the extent so specified in the case of Section
501(3)), whether directly or indirectly by reason of any reference elsewhere
herein to any such Section or by reason of any reference in any such Section to
any other provision herein or in any other document, but the remainder of this
Indenture and such Securities shall be unaffected thereby.

      Notwithstanding any Covenant Defeasance with respect to Section 801, any
Person that would otherwise have been required to assume the obligations of the
Company pursuant to said Section shall be required, as a condition to any
merger, consolidation, conveyance, transfer or lease contemplated thereby, to
assume the obligations of the Company to the Trustee under Sections 607 and
1205.

SECTION 1204. Conditions to Defeasance or Covenant Defeasance.

      The following shall be the conditions to the application of Section 1202
or Section 1203 to any Securities:

      (1) The Company shall irrevocably have deposited or caused to be deposited
with the Trustee (or another trustee which satisfies the requirements
contemplated by Section 609 and agrees to comply with the provisions of this
Article 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 benefits of the Holders of such Securities, (A) money in an amount, or
(B) Government Obligations 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, money in an amount, or
(C) a combination thereof, in each case 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 any such other qualifying trustee)
to pay and discharge, the principal of and any premium and interest on such
Securities on the respective Stated Maturities or on the Redemption Date, in
accordance with the terms of this Indenture and such Securities.

      (2) In the event of an election to have Section 1202 apply to any
Securities, the Company shall have delivered to the Trustee an Opinion of
Counsel stating that (A) the Company has received from, or there has been
published by, the Internal Revenue Service a ruling or (B) since the date of
this instrument, there has been a change in the applicable Federal income tax
law, in the case of either (A) or (B) to the effect that, and based thereon such
opinion shall confirm that, the Holders of such Securities will not recognize
gain or loss for Federal income tax purposes as a result of the deposit,
Defeasance and discharge to be effected with respect to such Securities and will
be subject to Federal income tax on the same amount, in the same manner and at
the same times as would be the case if such deposit, Defeasance and discharge
were not to occur.

      (3) In the event of an election to have Section 1203 apply to any
Securities, the Company shall have delivered to the Trustee an Opinion of
Counsel to the effect that the


                                       58
<PAGE>
Holders of such Securities will not recognize gain or loss for Federal income
tax purposes as a result of the deposit and Covenant Defeasance to be effected
with respect to such Securities and will be subject to Federal income tax on the
same amount, in the same manner and at the same times as would be the case if
such deposit and Covenant Defeasance were not to occur.

      (4) No event which is, or after notice or lapse of time or both would
become, an Event of Default with respect to such Securities or any other
Securities shall have occurred and be continuing at the time of such deposit or,
with regard to any such event specified in Sections 501(4) and (5), at any time
on or prior to the 90th day after the date of such deposit (it being understood
that this condition shall not be deemed satisfied until after such 90th day).

      (5) Such Defeasance or Covenant Defeasance shall not result in a breach or
violation of, or constitute a default under, any indenture or other agreement or
instrument for borrowed money to which the Company is a party or by which it is
bound.

      (6) Such Defeasance or Covenant Defeasance shall not result in the trust
arising from such deposit constituting an investment company within the meaning
of the Investment Company Act unless such trust shall be registered under the
Investment Company Act or exempt from registration thereunder.

      (7) If such Securities are to be redeemed prior to Stated Maturity (other
than from mandatory sinking fund payments or analogous payments), notice of such
redemption shall have been duly given pursuant to this Indenture or provision
therefor satisfactory to the Trustee shall have been made.

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

SECTION 1205. Deposited Money and Government Obligations to Be Held in Trust;
              Miscellaneous Provisions.

      Subject to the provisions of the last paragraph of Section 1003, all money
and Government Obligations (including the proceeds thereof and the interest
thereon) deposited with the Trustee or other qualifying trustee (solely for
purposes of this Section and Section 1206, the Trustee and any such other
trustee are referred to collectively as the "Trustee") pursuant to Section 1204
in respect of any Securities shall be held in trust and applied by the Trustee,
in accordance with the provisions of such Securities and this Indenture, to the
payment, either directly or through any such Paying Agent (including the Company
acting as its own Paying Agent) as the Trustee may determine, to the Holders of
such Securities, of all sums due and to become due thereon in respect of
principal and any premium and interest, but money so held in trust need not be
segregated from other funds except to the extent required by law.

      The Company shall pay and indemnify the Trustee against any tax, fee or
other charge imposed on or assessed against the Government Obligations deposited
pursuant to


                                       59
<PAGE>
Section 1204 or the principal and interest received in respect thereof other
than any such tax, fee or other charge which by law is for the account of the
Holders of Outstanding Securities.

      Anything in this Article to the contrary notwithstanding, the Trustee
shall deliver or pay to the Company from time to time upon Company Request any
money or Government Obligations held by it as provided in Section 1204 with
respect to any Securities which, in the opinion of a nationally recognized firm
of independent public accountants expressed in a written certification thereof
delivered to the Trustee, are in excess of the amount thereof which would then
be required to be deposited to effect the Defeasance or Covenant Defeasance, as
the case may be, with respect to such Securities.

SECTION 1206. Reinstatement.

      If the Trustee or the Paying Agent is unable to apply any money in
accordance with this Article with respect to any Securities by reason of any
order or judgment of any court or Governmental Authority enjoining, restraining
or otherwise prohibiting such application, then the obligations under this
Indenture and such Securities from which the Company has been discharged or
released pursuant to Section 1202 or 1203 shall be revived and reinstated as
though no deposit had occurred pursuant to this Article with respect to such
Securities, until such time as the Trustee or Paying Agent is permitted to apply
all money held in trust pursuant to Section 1205 with respect to such Securities
in accordance with this Article; provided, however, that if the Company makes
any payment of principal of or any premium or interest on any such Security
following such reinstatement of its obligations, the Company shall be subrogated
to the rights (if any) of the Holders of such Securities to receive such payment
from the money so held in trust.

SECTION 1207. Qualifying Trustee.

      Any trustee appointed pursuant to Section 1204 for the purpose of holding
trust funds deposited pursuant to that Section shall be appointed under an
agreement in form acceptable to the Trustee and shall provide to the Trustee a
certificate of such trustee, upon which certificate the Trustee shall be
entitled to conclusively rely, that all conditions precedent provided for herein
to the related Defeasance or Covenant Defeasance have been complied with. In no
event shall the Trustee be liable for any acts or omissions of said trustee.

      This Security is one of a duly authorized issue of securities of the
Company (herein called the "Securities"), issued and to be issued in one or more
series under a Senior Indenture, dated as of ___________, ___ as supplemented
and amended from time to time by ______________ (herein called the "Indenture"),
between the Company and The Bank of New York, as Trustee (herein called the
"Trustee", which term includes any successor trustee under the Indenture), to
which Indenture and all indentures supplemental thereto reference is hereby made
for a statement of the respective rights, limitations of rights, duties and
immunities thereunder of the Company, the Trustee and the Holders of the
Securities and of the terms upon which the Securities are, and are to be,
authenticated and delivered. This Security is one of the series designated on
the face hereof [if applicable insert --, limited in aggregate principal amount
to $___________].

      All terms used in this Security that are defined in the Indenture shall
have the meaning assigned to them in the Indenture.

      [If applicable, insert - The Securities of this series are subject to
redemption upon not less than 30 nor more than 60 days' notice by mail, at any

the Company. The Redemption Price for any Security so redeemed shall be equal to
100% of the principal amount of such Securities then Outstanding plus accrued
and unpaid interest up to but not including the date fixed for redemption. In
the event of redemption of this Security in part only, a new Security or
Securities of this series for the unredeemed portion hereof will be issued in
the name of the Holder hereof upon the cancellation hereof.]

      [Installments of accrued and unpaid interest whose Stated Maturity is on
or prior to the Redemption Date will be payable to the Holders of the Securities
of this series, or one or more Predecessor Securities, registered as such at the
close of business on the relevant Regular Record Dates according to their
terms.]

defeasance of the entire indebtedness on this security, upon compliance by the
Company with certain conditions set forth therein.

      [If the Security is not an Original Issue Discount Security, - If an Event
of Default with respect to Securities of this series shall occur and be
continuing, the principal of the Securities of this series may be declared due
and payable in the manner and with the effect provided in the Indenture.] [If
the security is an Original Issue Discount Security, - If an Event of Default
with respect to Securities of this series shall occur and be continuing, an
amount of principal of the Securities of this series may be declared due and
payable in the manner and with the effect provided in the Indenture. Such amount
shall be equal to - insert formula for determining the amount.

      Upon payment of the amount of principal so declared due and payable [if
applicable insert-- and of interest on any overdue principal and overdue
interest (in each


                                      A-4
<PAGE>
case to the extent that the payment of such interest shall be legally
enforceable)], all of the Company's obligations in respect of the payment of the
principal of and interest, if any, on the Securities of this series shall
terminate.]

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

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

      As provided in the Indenture and subject to certain limitations therein
set forth, the transfer of this Security is registrable in the Security
Register, upon surrender of this Security for registration of transfer at the
office or agency of the Company in any place where the principal of (and
premium, if any) and interest on this Security are payable, duly endorsed by, or
accompanied by a written instrument of transfer in form satisfactory to the
Company and the Security Registrar duly executed by, the Holder hereof or his
attorney duly authorized in writing, and thereupon one or more new Securities of
this series, of authorized denominations and for the same aggregate principal
amount, will be issued to the designated transferee or transferees.

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

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

      The Company, the Trustee and any agent of the Company or the Trustee may
treat the Person in whose name this Security is registered as the owner hereof
for all purposes,


                                      A-5
