            Section 104. ACTS OF SECURITYHOLDERS. (a) Any request, demand,

this Indenture to be given or taken by Securityholders or Securityholders of any
series may be embodied in and evidenced by one or more instruments of
substantially similar tenor signed by such Securityholders 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 [or the Guarantor or both of them]. If any Securities are denominated in
coin or currency other than that of the United States, then for the purposes of
determining whether the Holders of the requisite principal amount of Securities
have taken any action as herein described, the principal amount of such
Securities shall be deemed to be that amount of United States dollars that could
be obtained for such principal amount on the basis of the spot rate of exchange
into United States dollars for the currency in which such Securities are
denominated (as evidenced to the Trustee by an Officers' Certificate) as of the
date the taking of such action by the Holders of such requisite principal amount
is evidenced to the Trustee as provided in the immediately preceding sentence.
Such instrument or instruments (and the action embodied therein and evidenced
thereby) are herein sometimes referred to as the "Act" of the Securityholders
signing such instrument or instruments. Proof of execution of any such
instrument or of a writing appointing any such agent shall be sufficient for any
purpose of this Indenture and (subject to Section 601) conclusive in favor of
the Trustee [, the Guarantor] and the Company, if made in the manner provided in
this Section.

            (b) The fact and date of the execution by any Person of any such
instrument or writing may be proved by

<Page>
                                                                              15


the affidavit of a witness to such execution or by the 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 an officer of a
corporation or a member of a partnership, on behalf of such corporation or
partnership, such certificate or affidavit shall also constitute sufficient
proof of his authority. The fact and date of the execution of any such
instrument or writing, or the authority of the person executing the same, may
also be proved in any other manner which the Trustee deems sufficient.

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

            (d) If the Company [or the Guarantor] shall solicit from the Holders
any request, demand, authorization, direction, notice, consent, waiver or other
action, the Company [or the Guarantor, as the case may be,] may, at its option,
by Board Resolution or Guarantor's Board Resolution, as applicable, fix in
advance a record date for the determination of Holders entitled to give such
request, demand, authorization, direction, notice, consent, waiver or other
action, but the Company [or the Guarantor, as the case may be,] shall have no
obligation to do so. If such a record date is fixed, such request, demand,
authorization, direction, notice, consent, waiver or other action may be given
before or after the record date, but only the Holders of record at the close of
business on the record date shall be deemed to be Holders for the purposes of
determining whether Holders of the requisite proportion of Securities
Outstanding have authorized or agreed or consented to such request, demand,
authorization, direction, notice, consent, waiver or other action, and for that
purpose the Securities Outstanding shall be computed as of the record date;
provided that no such authorization, agreement or consent by the Holders on the
record date shall be deemed effective unless it shall become effective pursuant
to the provisions of this Indenture not later than six months after the record
date.

            (e) Any request, demand, authorization, direc tion, notice, consent,

Security issued upon the transfer thereof or in exchange therefor or in lieu
thereof, in respect of anything done or suffered to be done by the Trustee or
the Company [or the Guarantor] in reliance thereon whether or not notation of
such action is made upon such Security.

            Section 105. NOTICES, ETC., TO TRUSTEE [, GUARANTOR] AND COMPANY.
Any request, demand, authorization, direction, notice, consent, waiver or Act of
Securityholders 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 Securityholder or by the Company [or the
      Guarantor] shall be sufficient for every purpose hereunder if made, given,
      furnished or filed in writing to or with the Trustee at its Corporate
      Trust Office, or

            (2) the Company [or the Guarantor] by the Trustee or by any
      Securityholder shall be sufficient for every purpose hereunder (except as
      provided in Section 501(4) or, in the case of a request for repayment, as
      specified in the Security carrying the right to repayment) if in writing
      and mailed, first-class postage prepaid, to the Company [or the Guarantor,
      as the case may be,] 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 [or
      the Guarantor, as the case may be,].

            Section 106. NOTICES TO SECURITYHOLDERS; WAIVER. Where this
Indenture or any Security provides for notice to Securityholders of any event,
such notice shall be sufficiently given (unless otherwise herein or in such
Security expressly provided) if in writing and mailed, first-class postage
prepaid, to each Securityholder affected by such event, at his address as it
appears in the Security Register, not later than the latest date, and not
earlier than the earliest date, prescribed for the giving of such notice. In any
case where notice to Securityholders is given by mail, neither the failure to
mail such notice, nor

<Page>
                                                                              17


any defect in any notice so mailed, to any particular Securityholder shall
affect the sufficiency of such notice with respect to other Securityholders.
Where this Indenture or any Security 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 Securityholders 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 as a
result of a strike, work stoppage or otherwise, it shall be impractical to mail
notice of any event to any Securityholder when such notice is required to be
given pursuant to any provision of this Indenture, then any method of
notification as shall be satisfactory to the Trustee [, the Guarantor] and the
Company shall be deemed to be a sufficient giving of such notice.

            Section 107. CONFLICT WITH TRUST INDENTURE ACT. If any provision
hereof limits, qualifies or conflicts with the duties imposed by any of Sections
310 to 317, inclusive, of the Trust Indenture Act through the operation of
Section 318(c) thereof, such imposed duties shall control.

            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 [each of] the Company [and the Guarantor] 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
any Securities, express or implied, shall give to any Person, other than the
parties hereto and their successors hereunder, any Authenticating Agent or
Paying Agent, the Security Registrar and the Holders of Securities (or such of
them as may be affected thereby), any benefit or any legal or equitable right,
remedy or claim under this Indenture.

            Section 112. GOVERNING LAW. This Indenture shall be construed in
accordance with and governed by the laws of the State of New York.

            Section 113. COUNTERPARTS. This instrument may be executed in any
number of counterparts, each of which so executed shall be deemed to be an
original, but all such counterparts shall together constitute but one and the
same instrument.

            Section 114. JUDGMENT CURRENCY. The Company [and the Guarantor each]
agrees, to the fullest extent that it may effectively do so under applicable
law, that (a) if for the purpose of obtaining judgment in any court it is
necessary to convert the sum due in respect of the principal of, or premium or
interest, if any, on the Securities of any series (the "Required Currency") into
a currency in which a judgment will be rendered (the "Judgment Currency"), the
rate of exchange used shall be the rate at which in ac cordance with normal
banking procedures the Trustee could purchase in New York City the Required
Currency with the Judgment Currency on the Banking Day (as defined below)
immediately preceding the date on which final unappealable judgment is given and
(b) its obligations under this Indenture to make payments in the Required
Currency (i) shall not be discharged or satisfied by any tender, or any recovery
pursuant to any judgment (whether or not entered in accordance with subsection
(a)), in any currency other than the Required Currency, except to the extent
that such tender or recovery shall result in the actual receipt, by the payee,
of the full amount of the Required Currency expressed to be payable in respect
of such payments, (ii) shall be enforceable as an alternative or additional
cause of action for the purpose of recovering in the Required Currency the
amount, if any, by which such actual

                                                                              19


receipt shall fall short of the full amount of the Required Currency so
expressed to be payable and (iii) shall not be affected by judgment being
obtained for any other sum due under this Indenture. For purposes of the
foregoing, "Banking Day" means any day except a Saturday, Sunday or a legal
holiday in New York City or a day on which banking institutions in New York City
are authorized or required by law or executive order to close.

approved by or pursuant to a Board Resolution, the Company shall deliver to the
Trustee the Board Resolution by or pursuant to which such form of Security has
been approved, which Board Resolution shall have attached thereto a true and
correct copy of the form of Security which has been approved thereby or, if a
Board Resolution authorizes a specific officer or officers to approve a form of

            Section 204. SECURITIES ISSUABLE IN THE FORM OF A GLOBAL SECURITY.
(a) If the Company shall establish pursuant to Sections 202 and 301 that the
Securities of a particular series are to be issued in whole or in part in the
form of one or more Global Securities, then the Company shall execute and the
Trustee or its agent shall, in accordance with Section 303 and the Company
Request delivered to the Trustee or its agent thereunder, authenticate and
deliver, such Global Security or Securities, which (i) shall represent, and
shall be denominated in an amount equal to the aggregate principal amount of,
the Outstanding Securities of such series to be represented by such Global
Security or Securities, or such portion thereof as the Company shall specify in
a Company Request, (ii) shall be registered in the name of the Depositary for
such Global Security or Securities or its nominee, (iii) shall be delivered by
the Trustee or its agent to the Depositary or pursuant to the Depositary's
instruction and (iv) shall bear a legend substantially to the following effect:
"Unless and until it is exchanged in whole or in part for the individual
Securities represented hereby, this Global Security may not be transferred
except as a whole by the Depositary to a nominee of the Depositary or by a
nominee of the Depositary to the Depositary or another nominee of the Depositary
or by the Depositary or any such nominee to a successor Depositary or a nominee
of such successor Depositary."

            (b) Notwithstanding any other provisions of this Section 204 or of
Section 305, and subject to the provisions of paragraph (c) below, unless the
terms of a Global Security expressly permit such Global Security to be exchanged
in whole or in part for individual Securities, a Global Security may be
transferred, in whole but not in part and in the manner provided in Section 305,
only to a nominee of the Depositary for such Global Security, or to the
Depositary, or a successor Depositary for such Global Security selected or
approved by the Company, or to a nominee of such successor Depositary.

                                                                              22


            (c) (i) If at any time the Depositary for a Global Security notifies
the Company that it is unwilling or unable to continue as Depositary for such
Global Security or if at any time the Depositary for the Securities for such
series ceases to be a clearing agency registered under the Securities Exchange
Act of 1934, as amended, or other applicable statute or regulation, the Company
shall appoint a successor Depositary with respect to such Global Security. If a
successor Depositary for such Global Security 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 or its agent, upon
receipt of a Company Request for the authentication and delivery of individual
Securities of such series in exchange for such Global Security, will
authenticate and deliver, individual Securities of such series of like tenor and
terms in an aggregate principal amount equal to the principal amount of the
Global Security in exchange for such Global Security.

      (ii) The Company may at any time and in its sole discretion determine that
the Securities of any series or portion thereof issued or issuable 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 Request for the authentication and delivery of
individual Securities of such series in exchange in whole or in part for such
Global Security, will authenticate and deliver individual Securities of such
series of like tenor and terms in definitive form in an aggregate principal
amount equal to the principal amount of such Global Security or Securities
representing such series or portion thereof in exchange for such Global Security
or Securities.

      (iii) If specified by the Company pursuant to Sections 202 and 301 with
respect to Securities issued or issuable in the form of a Global Security, the
Depositary for such Global Security may surrender such Global Security in
exchange in whole or in part for individual Securities of such series of like
tenor and terms in definitive form on such terms as are acceptable to the
Company and such Depositary. Thereupon the Company shall execute, and the
Trustee or its agent shall authenticate and deliver, without

service charge, (1) to each Person specified by such Depositary a new Security
or Securities of the same series of like tenor and terms and 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 of like tenor and terms and in
an authorized denomination equal to the difference, if any, between the
principal amount of the surrendered Global Security and the aggregate principal
amount of Securities delivered to the Holders thereof.

      (iv) In any exchange provided for in any of the preceding three
paragraphs, the Company will execute and the Trustee or its agent will
authenticate and deliver individual Securities in definitive registered form in
authorized denominations. Upon the exchange of the entire principal amount of a
Global Security for individual Securities, such Global Security shall be
canceled by the Trustee or its agent. Except as provided in the preceding
paragraph, 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 or the
Security Registrar. The Trustee or the Security Registrar shall deliver such
Securities to the Persons in whose names such Securities are so registered.

      limitation, the Securities of any other series; and

            (15) any other terms of the series, which shall not be inconsistent
      with the provisions of this Indenture,

all upon such terms as may be determined in or pursuant to a Board Resolution or
in or pursuant to a supplemental indenture with respect to such series. All
Securities of the same series shall be substantially identical in tenor and
effect, except as to denomination.

            The form of the Securities of each series shall be established
pursuant to the provisions of this Indenture in or pursuant to the Board
Resolution or in or pursuant to the supplemental indenture creating such series.
The Securities of each series shall be distinguished from the Securities of each
other series in such manner, reasonably satisfactory to the Trustee, as the
Board of Directors may determine.

            Unless otherwise provided with respect to Securities of a particular
series, the Securities of any series may only be issuable in registered form,
without coupons.

            Any terms or provisions in respect of the Securities of any series
issued under this Indenture may be determined pursuant to this Section by
providing in a Board Resolution or supplemental indenture for the method by
which such terms or provisions shall be determined.

            Section 302. DENOMINATIONS. The Securities of each series shall be
issuable in such denominations and

<Page>
                                                                              29


currency as shall be provided in the provisions of this Indenture or in or
pursuant to the Board Resolution or the supplemental indenture creating such
series. In the absence of any such provisions with respect to the Securities of
any series, the Securities of that series shall be issuable only in fully
registered form in denominations of $1,000 and any integral multiple thereof.

            Section 303. EXECUTION, AUTHENTICATION AND DELIVERY AND DATING. The
Securities shall be executed on behalf of the Company by its Chairman of the
Board, its President, one of its Vice Presidents or its Treasurer under its
corporate seal reproduced thereon and attested by its Secretary or one of its
Assistant Secretaries. The signature of any of these officers on the Securities
may be manual or facsimile.

            Securities bearing the manual or facsimile signatures of individuals
who were at any time the proper officers of the Company shall bind the Company,
notwith standing 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; and the Trustee shall, upon Company Order,
authenticate and make available for delivery such Securities as in this
Indenture provided and not otherwise.

            Prior to any such authentication and delivery, the Trustee shall be
entitled to receive, in addition to any Officers' Certificate and Opinion of
Counsel required to be furnished to the Trustee pursuant to Section 102, and the
Board Resolution and any certificate relating to the issuance of the series of
Securities required to be furnished pursuant to Section 202, an Opinion of
Counsel stating that:

            (1) all instruments furnished to the Trustee conform to the
      requirements of the Indenture and constitute sufficient authority
      hereunder for the Trustee to authenticate and deliver such Securities;

<Page>
                                                                              30


            (2) the form and terms (or in connection with the issuance of
      medium-term Securities under Section 311, the manner of determining the
      terms) of such Securities have been established in conformity with the
      provisions of this Indenture;

            (3) all laws and requirements with respect to the execution and
      delivery by the Company of such Securities have been complied with, the
      Company has the corporate power to issue such Securities and such
      Securities have been duly authorized and delivered by the Company and,
      assuming due authentication and delivery by the Trustee, constitute legal,
      valid and binding obligations of the Company enforceable in accordance
      with their terms (subject, as to enforcement of remedies, to applicable
      bankruptcy, reorganization, insolvency, fraudulent conveyance, moratorium
      or other laws and legal principles affecting creditors' rights generally
      from time to time in effect and to general equitable principles, whether
      applied in an action at law or in equity) and entitled to the benefits of
      this Indenture, equally and ratably with all other Securities, if any, of
      such series Outstanding; and

            (4) such other matters as the Trustee may reasonably request;

and, if the authentication and delivery relates to a new series of Securities
created by an indenture supplemental hereto, also stating that all laws and
requirements with respect to the form and execution by the Company of the
supplemental indenture with respect to that series of Securities have been
complied with, the Company has cor porate power to execute and deliver any such
supplemental indenture and has taken all necessary corporate action for those
purposes and any such supplemental indenture has been executed and delivered and
constitutes the legal, valid and binding obligation of the Company enforceable
in accordance with its terms (subject, as to enforcement of remedies, to
applicable bankruptcy, reorganization, insolvency, fraudulent conveyance,
moratorium or other laws and legal

<Page>
                                                                              31


principles affecting creditors' rights generally from time to time in effect and
to general equitable principles, whether applied in an action at law or in
equity).

            The Trustee shall not be required to authenticate such Securities if
the issue thereof will adversely affect the Trustee's own rights, duties or
immunities under the Securities and this Indenture.

            Unless otherwise provided in the form of Security for any series,
all Securities shall be dated the date of their authentication.

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

            Section 304. TEMPORARY SECURITIES. Pending the preparation of
definitive Securities of any series, the Company may execute, and, upon receipt
of the documents required by Section 303, together with a Company Order, the
Trustee shall authenticate and deliver, temporary Securities which are printed,
lithographed, typewritten, mimeographed or otherwise produced, in any authorized
denomination, substantially of the tenor of the definitive Securities in lieu of
which they are issued and with such appropriate insertions, omissions,
substitutions and other variations as the officers executing such Securities may
determine, as evidenced by their execution of such Securities.

            If temporary Securities of any series are issued, the Company will
cause definitive Securities of such series to be prepared without unreasonable
delay. After the preparation of definitive Securities, the temporary Securities
of such series shall be exchangeable for definitive Securities of such series
upon surrender of the temporary Securities of such series at the office or
agency of the Company in a Place of Payment, without charge to the Holder; and
upon surrender for cancellation of any one or

<Page>
                                                                              32


more temporary Securities the Company shall execute and the Trustee shall
authenticate and deliver in exchange therefor a like principal amount of
definitive Securities of such series of authorized denominations and of like
tenor and terms. Until so exchanged the temporary Securities of such series
shall in all respects be entitled to the same bene fits under this Indenture as
definitive Securities of such series.

            Section 305. REGISTRATION, TRANSFER AND EXCHANGE. The Company shall
keep or cause to be kept a register (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, or of
Securities of a particular series, and for transfers of Securities or of
Securities of such series. Any such register shall be in written form or in any
other form capable of being converted into written form within a reasonable
time. At all reasonable times the information contained in such register or
registers shall be available for inspection by the Trustee at the office or
agency to be maintained by the Company as provided in Section 1002.

            Subject to Section 204, upon surrender for transfer of any Security
of any series at the office or agency of the Company in a Place of Payment, the
Company shall execute, and the Trustee shall authenticate and make available for
delivery, in the name of the designated transferee or transferees, one or more
new Securities of such series of any authorized denominations, of a like
aggregate principal amount and Stated Maturity and of like tenor and terms.

            Subject to Section 204, at the option of the Holder, Securities of
any series may be exchanged for other Securities of such series of any
authorized denominations, of a like aggregate principal amount and Stated
Maturity and of like tenor and 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
make available for delivery, the Securities which the

<Page>
                                                                              33


Securityholder making the exchange is entitled to receive.

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

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

            Unless otherwise provided in the Security to be transferred or
exchanged, no service charge shall be made on any Securityholder for any
transfer or exchange of Securities, but the Company may (unless otherwise
provided in such Security) require payment of a sum sufficient to cover any tax
or other governmental charge that may be imposed in connection with any transfer
or exchange of Securities, other than exchanges pursuant to Section 304 or 906
not involving any transfer.

            The Company shall not be required (i) to issue, transfer or exchange
any Security of any series during a period beginning at the opening of business
15 days before the day of the mailing of a notice of redemption of Securities of
such series selected for redemption under Section 1103 and ending at the close
of business on the date of such mailing, or (ii) to transfer or exchange any
Security so selected for redemption in whole or in part, except for the portion
of such Security not so selected for redemption.

            None of the Company, [the Guarantor,] the Trustee, any agent of the
Trustee, any Paying Agent or the Security Registrar 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 for
maintaining, supervising or reviewing any records relating to such beneficial
ownership interests.

            The Company initially appoints the Trustee to act

<Page>
                                                                              34


as Security Registrar for the Securities on its behalf. The Company may at any
time and from time to time authorize any Person to act as Security Registrar in
place of the Trustee with respect to any series of Securities issued under this
Indenture.

            Section 306. MUTILATED, DESTROYED, LOST AND STOLEN SECURITIES. If
(i) any mutilated Security is surrendered to the Trustee, or the Company [, the
Guarantor] and the Trustee receive evidence to their satisfaction of the
destruction, loss or theft of any Security, and (ii) there is delivered to the
Company [, the Guarantor] and the Trustee such security or indemnity as may be
required by them to save each of them harmless, then, in the absence of notice
to the Company [, the Guarantor] or the Trustee that such Security has been
acquired by a bona fide purchaser, the Company shall execute and upon its
request the Trustee shall authenticate and deliver, in exchange for or in lieu
of any such mutilated, destroyed, lost or stolen Security, a new Security of
like tenor, series, Stated Maturity and principal amount, 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 [and the Guarantor], whether or not the
destroyed, lost or stolen Security shall be at any time enforceable by anyone,
and shall be entitled to all the benefits of this Indenture equally and
proportionately with

<Page>
                                                                              35


any and all other Securities of the same series duly issued hereunder.

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

            Section 307. PAYMENT OF INTEREST; INTEREST RIGHTS PRESERVED. Unless
otherwise provided with respect to such Security pursuant to Section 301,
interest on any Security which is payable, and is punctually paid or duly
provided for, on any Interest Payment Date shall be paid to the Person in whose
name that Security (or one or more Predecessor Securities) is registered at the
close of business on the Regular Record Date for such interest.

            Any interest on any Security which is payable, but is not punctually
paid or duly provided for, on any Interest Payment Date (herein called
"Defaulted Interest") shall forthwith cease to be payable to the registered
Holder on the relevant Regular Record Date by virtue of his having been such
Holder; and, except as hereinafter provided, such Defaulted Interest may be paid
by the Company [or the Guarantor], at its election in each case, as provided in
Clause (1) or Clause (2) below:

            (1) The Company [or the Guarantor], may elect to make payment of any
      Defaulted Interest to the Persons in whose names any such Securities (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 [or
      the Guarantor, as the case may be,] shall notify the Trustee in writing of
      the amount of Defaulted Interest proposed to be paid on each such Security
      and the date of the proposed payment, and at the same time the Company [or
      the Guarantor, as the case may be] 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

<Page>
                                                                              36


      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 nor 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 [or Guarantor, as the case may be,] of such Special
      Record Date and, in the name and at the expense of the Company [or the
      Guarantor], 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 the Holder of each such Security at his address 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 mailed as
      aforesaid, such Defaulted Interest shall be paid to the Persons in whose
      names such Securities (or their respective Predecessor Securities) are
      registered on such Special Record Date and shall no longer be payable
      pursuant to the following Clause (2).

            (2) The Company [or the Guarantor] may make payment of any Defaulted
      Interest in any other lawful manner not inconsistent with the requirements
      of any securities exchange on which such Securities may be listed, and
      upon such notice as may be required by such exchange, if, after notice
      given by the Company [or Guarantor, as the case may be,] to the Trustee of
      the proposed payment pursuant to this Clause, such manner of payment shall
      be deemed practicable by the Trustee.

            If any installment of interest the Stated Maturity of which is on or
prior to the Redemption Date for any Security called for redemption pursuant to
Article Eleven is not paid or duly provided for on or prior to the Redemption
Date in accordance with the foregoing provisions of this Section, such interest
shall be payable as part of the Redemption Price of such Securities.

                                                                              37


            Subject to the foregoing provisions of this Section, each Security
delivered under this Indenture upon 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 Guarantor],
the Trustee and any agent of the Company [, the Guarantor,] or the Trustee may
treat the Person in whose name any Security is registered in the Security
Register as the owner of such Security for the purpose of receiving payment of
principal of (and premium, if any), and (subject to Section 307) interest on,
such Security and for all other purposes whatsoever, whether or not such
Security be overdue, and neither the Company, [the Guarantor] the Trustee nor
any agent of the Company [, the Guarantor] or the Trustee shall be affected by
notice to the contrary.

            Section 309. CANCELLATION. All Securities surrendered for payment,
redemption, transfer, conversion or exchange or credit against a sinking fund
shall, if surren dered to any Person other than the Trustee, be delivered to the
Trustee and, if not already canceled, shall be promptly canceled by it. The
Company [or the Guarantor] may at any time deliver to the Trustee for
cancellation any Securities previously authenticated and delivered hereunder
which the Company [or the Guarantor] may have acquired in any manner whatsoever,
and all Securities so delivered shall be promptly canceled by the Trustee. No
Security shall be authenticated in lieu of or in exchange for any Securities
canceled as provided in this Section, except as expressly permitted by this
Indenture. The Trustee shall return all canceled Securities to the Company.

            Section 310. COMPUTATION OF INTEREST. Unless otherwise provided as
contemplated in Section 301, interest on the Securities shall be calculated on
the basis of a 360-day year of twelve 30-day months.

            Section 311. MEDIUM-TERM SECURITIES. Notwithstanding any contrary
provision herein, if all Securities of a series are not to be originally issued
at one time, it shall not be necessary for the Company to deliver to the Trustee
an Officers' Certificate, Board

<Page>
                                                                              38


Resolution, supplemental indenture, Opinion of Counsel or Company Request
otherwise required pursuant to Sections 202, 301 and 303 at or prior to the time
of authentication of each Security of such series if such documents are
delivered to the Trustee or its agent at or prior to the authentication upon
original issuance of the first Security of such series to be issued; provided
that any subsequent request by the Company to the Trustee to authenticate
Securities of such series upon original issuance shall constitute a
representation and warranty by the Company that as of the date of such request,
the statements made in the Officers' Certificate delivered pursuant to Section
102 shall be true and correct as if made on such date.

            An Officers' Certificate, supplemental indenture or Board Resolution
delivered by the Company to the Trustee in the circumstances set forth in the
preceding paragraph may provide that Securities which are the subject thereof
will be authenticated and delivered by the Trustee or its agent on original
issue from time to time upon the telephonic or written order of persons
designated in such Officers' Certificate, Board Resolution or supplemental
indenture (any such telephonic instructions to be confirmed promptly in writing
by such persons) and that such persons are authorized to determine, consistent
with such Officers' Certificate, supplemental indenture or Board Resolution,
such terms and conditions of said Securities as are specified in such Officers'
Certificate, supplemental indenture or Board Resolution.

            Section 312. 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 of any change in the "CUSIP"

<Page>
                                                                              39


numbers.

            SECTION 313. GLOBAL SECURITIES. (a) Each Global Security
authenticated under this Indenture shall be registered in the name of the
Depositary designated by the Company for such Global Security or a nominee
thereof and delivered to such Depositary or a nominee thereof or custodian
therefor, and each such Global Security shall constitute a single Security for
all purposes of this Indenture.

            (b) Notwithstanding any other provision of this Indenture, no Global
Security may be exchanged in whole or in part for Securities registered, and no
transfer of a Global Security in whole or in part may be registered, in the name
of any Person other than the Depositary for such Global Security or a nominee
thereof unless (i) such Depositary (A) has notified the Company that it is
unwilling or unable to continue as Depositary for such Global Security or (B)
has ceased to be a clearing agency registered as such under the Exchange Act or
announces an intention permanently to cease business or does in fact do so or
(ii) there shall have occurred and be continuing an Event of Default with
respect to such Global Security.

            (c) If any Global Security is to be exchanged for other Securities
or canceled in whole, it shall be surrendered by or on behalf of the Depositary
or its nominee to the Trustee, as Security Registrar, for exchange or
cancellation, as provided in this Article Three. If any Global Security is to be
exchanged for other Securities or canceled in part, or if another Security is to
be exchanged in whole or in part for a beneficial interest in any Global
Security, in each case, as provided in Section 305, then either (i) such Global
Security shall be so surrendered for exchange or cancellation, as provided in
this Article Three or (ii) the principal amount thereof shall be reduced or
increased by an amount equal to the portion thereof to be so exchanged or
canceled, or equal to the principal amount of such other Security to be so
exchanged for a beneficial interest therein, as the case may be, by means of an
appropriate adjustment made on the records of the Trustee, as Security
Registrar, whereupon the Trustee, in accordance with the Applicable Procedures,
shall instruct the Depositary or its authorized representative to make a

<Page>
                                                                              40


corresponding adjustment to its records. Upon any such surrender or adjustment
of a Global Security, the Trustee shall, subject to Section 305 and as otherwise
provided in this Article Three authenticate and deliver any Securities issuable
in exchange for such Global Security (or any portion thereof) to or upon the
order of, and registered in such names as may be directed by, the Depositary or
its authorized representative. Upon the request of the Trustee in connection
with the occurrence of any of the events specified in the preceding paragraph,
the Company shall promptly make available to the Trustee a reasonable supply of
Securities that are not in the form of Global Securities. The Trustee shall be
entitled to rely upon any order, direction or request of the Depositary or its
authorized representative which is given or made pursuant to this Article Three
if such order, direction or request is given or made in accordance with the
Applicable Procedures.

            (d) Every Security authenticated and delivered upon registration of
transfer of, or in exchange for or in lieu of, a Global Security or any portion
thereof, whether pursuant to this Article Three or otherwise, shall be
authenticated and delivered in the form of, and shall be, a registered Global
Security, unless such Security is registered in the name of a Person other than
the Depositary for such Global Security or a nominee thereof, in which case such
Registered Security shall be authenticated and delivered in definitive, fully
registered form, without interest coupons.

            (e) The Depositary or its nominee, as registered owner of a Global
Security, shall be the Holder of such Global Security for all purposes under the
Indenture and the Registered Securities, and owners of beneficial interests in a
Global Security shall hold such interests pursuant to the Applicable Procedures.
Accordingly, any such owner's beneficial interest in a Global Security will be
shown only on, and the transfer of such interest shall be effected only through,
records maintained by the Depositary or its nominee or its Agent Members and
such owners of beneficial interests in a Global Security will not be considered
the owners or holders thereof.

                                  ARTICLE FOUR

                    SATISFACTION AND DISCHARGE OF INDENTURE;
                          DEFEASANCE; UNCLAIMED MONEYS

            SECTION 401. APPLICABILITY OF ARTICLE. If, pursuant to Section 301,
provision is made for the defeasance of Securities of a series and if the
Securities of such series are denominated and payable only in Dollars (except as
provided pursuant to Section 301), then the provisions of this Article Four
relating to defeasance of Securities shall be applicable except as otherwise
specified pursuant to Section 301 for Securities of such series. Defeasance
provisions, if any, for Securities denominated in a Foreign Currency may be
specified pursuant to Section 301.

            SECTION 402. SATISFACTION AND DISCHARGE OF INDENTURE; DEFEASANCE.
(a) If at any time (i) the Company shall have delivered to the Trustee for
cancellation all Securities of any series theretofore authenticated and
delivered (other than (1) any Securities of such series which shall have been
destroyed, lost or stolen and which shall have been replaced or paid as provided
in Section 306 and (2) Securities for whose payment money has theretofore been
deposited in trust and thereafter repaid to the Company as provided in Section
405) or (ii) all Securities of such series not theretofore delivered to the
Trustee for cancellation shall have become due and payable, or are by their
terms to become due and payable within one year or are to be called for
redemption within one year under arrangements satisfactory to the Trustee for
the giving of notice of redemption, and the Company shall deposit with the
Trustee as trust funds the entire amount in the Currency in which such
Securities are denominated (except as otherwise provided pursuant to Section
301) sufficient (in the opinion of a nationally recognized firm of independent
public accountants expressed in a written certification thereof delivered to the
Trustee) without consideration of any reinvestment and after payment of all
taxes or other charges and assessments in respect thereof payable by the
Trustee, to pay at maturity or upon redemption all Securities of such series not
theretofore delivered to the Trustee for cancellation, including principal and
premium, if any, and

                                                                              42


interest due or to become due on such date of maturity or redemption date, as
the case may be, no default with respect to the Securities has occurred and is
continuing on the date of such deposit, such deposit does not result in a breach
or violation of, or constitute a default under, the Indenture or any other
agreement or instrument to which the Company is a party and the Company delivers
an Officers' Certificate and an Opinion of Counsel each stating that such
conditions have been complied with and if in either case the Company shall also
pay or cause to be paid all other sums payable hereunder by the Company, then
this Indenture shall cease to be of further effect (except as to any surviving
rights of registration of transfer or exchange of such Securities herein
expressly provided for and rights to receive payments of principal of, and
premium, if any, and interest on, such Securities) with respect to the
Securities of such series, and the Trustee, on demand of the Company, shall
execute proper instruments acknowledging satisfaction of and discharging this
Indenture.

            (b) Subject to Sections 402(c), 403 and 407, the Company at any time
may terminate, with respect to Securities of a particular series, (i) all of the
Company's and the Guarantor's obligations under the Securities of such series
and this Indenture with respect to the Securities of such series ("legal
defeasance option") or (ii) the Company's and the Guarantor's obligations under
any covenants specified pursuant to Section 301 applicable to the Securities of
such series ("covenant defeasance option"). The Company may exercise its legal
defeasance option notwithstanding its prior exercise of its covenant defeasance
option.

            If the Company exercises the legal defeasance option, payment of the
Securities of the defeased series may not be accelerated because of an Event of
Default. If the Company exercises the covenant defeasance option, payment of the
Securities may not be accelerated because of an Event of Default related to the
specified covenants.

            Upon satisfaction of the conditions set forth herein and upon
request of the Company [or the Guarantor],

<Page>
                                                                              43


the Trustee shall acknowledge in writing the discharge of those obligations that
the Company terminates.

            (c) Notwithstanding clause (a) above and the exercise of the legal
defeasance option in clause (b) above, the Company's [and the Guarantor's]
obligations in Sections 305, 306, 405, 406, 407, 607, 608, 701 and 1002 shall
survive until the Securities of the defeased series have been paid in full.
Thereafter, the Company's [and the Guarantor's] obligations in Sections 607, 405
and 406 shall survive.

            SECTION 403. CONDITIONS OF DEFEASANCE. The Company may exercise the
legal defeasance option or the covenant defeasance option with respect to
Securities of a particular series only if:

            (1) the Company [or the Guarantor] irrevocably deposits in trust
      with the Trustee money or U.S. Government Obligations for the payment of
      principal of, and premium, if any, and interest on, the Securities of such
      series to maturity or redemption, as the case may be;

            (2) the Company [or the Guarantor] delivers to the Trustee a
      certificate from a nationally recognized firm of independent public
      accountants expressing their opinion that the payments of principal and
      interest when due and without reinvestment on the deposited U.S.
      Government Obligations plus any deposited money without investment will
      provide cash at such times and in such amounts as will be sufficient to
      pay the principal, premium, if any, and interest when due on all the
      Securities of such series to maturity or redemption, as the case may be;

            (3) 91 days pass after the deposit is made and during the 91-day
      period no Default specified in Section 501(5) or (6) with respect to the
      Company occurs which is continuing at the end of the period;

            (4) no Default has occurred and is continuing on the date of such
      deposit and after giving effect thereto;

<Page>
                                                                              44


            (5) the deposit does not constitute a default under any other
      agreement binding on the Company [or the Guarantor];

            (6) the Company [or the Guarantor] delivers to the Trustee an
      Opinion of Counsel to the effect that the trust resulting from the deposit
      does not constitute, or is qualified as, a regulated investment company
      under the Investment Company Act of 1940;

            (7) in the event of the legal defeasance option, the Company [or the
      Guarantor] shall have delivered to the Trustee an Opinion of Counsel
      stating that (i) the Company has received from the Internal Revenue
      Service a ruling, or (ii) since the date of this Indenture there has been
      a change in the applicable Federal income tax law, in either case to the
      effect that, and based thereon such Opinion of Counsel shall confirm that,
      the Holders of Securities of such series will not recognize income, gain
      or loss for Federal income tax purposes as a result of such defeasance and
      will be subject to Federal income tax on the same amounts, in the same
      manner and at the same times as would have been the case if such
      defeasance had not occurred;

            (8) in the event of the covenant defeasance option, the Company [or
      the Guarantor] shall have delivered to the Trustee an Opinion of Counsel
      to the effect that the Holders of Securities of such series will not
      recognize income, gain or loss for Federal income tax purposes as a result
      of such covenant defeasance and will be subject to Federal income tax on
      the same amounts, in the same manner and at the same times as would have
      been the case if such covenant defeasance had not occurred; and

            (9) the Company [or the Guarantor] delivers to the Trustee an
      Officers' Certificate and an Opinion of Counsel, each stating that all
      conditions precedent to the defeasance and discharge of the Securities of
      such series as contemplated by this Article Four have been complied with.

                                                                              45


            Before or after a deposit, the Company [or the Guarantor] may make
arrangements satisfactory to the Trustee for the redemption of Securities of
such series at a future date in accordance with Article Eleven.

            SECTION 404. APPLICATION OF TRUST MONEY. The Trustee shall hold in
trust money or U.S. Government Obligations deposited with it pursuant to this
Article Four. It shall apply the deposited money and the money from U.S.
Government Obligations through any paying agent and in accordance with this
Indenture to the payment of principal of, and premium, if any, and interest on,
the Securities of the defeased series.

            SECTION 405. REPAYMENT TO COMPANY [OR GUARANTOR]. The Trustee and
any paying agent shall promptly turn over to the Company [or the Guarantor] upon
request any excess money or securities held by them at any time.

            Subject to any applicable abandoned property law, the Trustee and
any paying agent shall pay to the Company [or the Guarantor] upon request any
money held by them for the payment of principal, premium or interest that
remains unclaimed for two years, and, thereafter, Holders entitled to such money
must look to the Company [or the Guarantor] for payment as general creditors and
all liability of the Trustee or such paying agent with respect to such money
shall thereupon cease.

            SECTION 406. INDEMNITY FOR U.S. GOVERNMENT OBLIGATIONS. The Company
[and the Guarantor (without duplication)] shall pay and shall indemnify the
Trustee and the Holders against any tax, fee or other charge imposed on or
assessed against deposited U.S. Government Obligations or the principal and
interest received on such U.S. Government Obligations.

            SECTION 407. REINSTATEMENT. If the Trustee or any paying agent is
unable to apply any money or U.S. Government Obligations in accordance with this
Article Four by reason of any legal proceeding or by reason of any order or
judgment of any court or government authority enjoining, restraining or
otherwise prohibiting such application, the Company's [and the Guarantor's]
obligations under this Indenture and the Securities of the defeased series shall
be

                                                                              46


revived and reinstated as though no deposit had occurred pursuant to this
Article Four until such time as the Trustee or any paying agent is permitted to
apply all such money or U.S. Government Obligations in accordance with this
Article Four.

                                  ARTICLE FIVE

voluntary or involuntary or be effected by operation of law or pursuant to any

      of such covenants and warranties in the Indenture which are not expressly
      stated to be for the benefit of a particular series of Securities being

       to the Trustee, in form satisfactory to the Trustee, the due and
       punctual payment of the principal of (and premium, if any) and
       interest on all the Securities and the performance of every covenant
       of this Indenture on the part of the Guarantor to be performed or
       observed;

                  (B) immediately after giving effect to such transaction, no
       Event of Default, and no event which, after notice or lapse of time,
       or both, would become an Event of Default, shall have happened and be
       continuing; and

                  (C) either the Guarantor or the successor Person has
       delivered to the Trustee an Officers' Certificate and an Opinion of
       Counsel each stating that such consolidation, amalgamation, merger,

            Section 502. ACCELERATION OF MATURITY; RESCISSION AND ANNULMENT.
If an Event of Default described in paragraph (1), (2), (3), (4), (5) or (8)
(if the Event of Default under paragraph (4), (5) or (8) is with respect to
less than all series of Securities then Outstanding) of Section 501 occurs
and is continuing with respect to any series, then and in each and every such
case, unless the principal of all the Securities of such series shall have
already become due and payable, either the Trustee or the Holders of not less
than 25% in aggregate principal amount of the Securities of such series then
Outstanding hereunder (each such series acting as a separate class), by
notice in writing to the Company [and the Guarantor] (and to the Trustee if
given by Holders), may declare the principal amount (or, if the Securities of
such series are Original Issue Discount Securities, such portion of the
principal amount as may be specified in the terms of that series) of all the
Securities of such series then Outstanding and all accrued interest thereon
to be due and payable immediately, and upon any such declaration the same
shall become and shall be immediately due and payable, anything in this
Indenture or in the Securities of such series contained to the contrary
notwithstanding. If an Event of Default described in paragraph (4), (5) or
(8) (if the Event of Default under paragraph (4), (5) or (8) is with respect
to all series of Securities then Outstanding), or (6) or (7) of Section 501
occurs and is continuing, then and in each and every such case, unless the
principal of all the Securities shall have

                                                                              49


already become due and payable, either the Trustee or the Holders of not less
than 25% in aggregate principal amount of all the Securities then Outstanding
hereunder (treated as one class), by notice in writing to the Company [and the
Guarantor] (and to the Trustee if given by Holders), may de clare the principal
amount (or, if any Securities are Original Issue Discount Securities, such
portion of the principal amount as may be specified in the terms thereof) of all
the Securities then Outstanding and all accrued interest thereon to be due and
payable immediately, and upon any such declaration the same shall become and
shall be immediately due and payable, anything in this Indenture or in the
Securities contained to the contrary notwithstanding.

            At any time after such a declaration of accel eration has been made
with respect to the Securities of any series and before a judgment or decree for
payment of the money due has been obtained by the Trustee as hereinafter in this
Article provided, the Holders of a majority in principal amount of the
Outstanding Securities of such series, by written notice to the Company and the
Trustee, may rescind and annul such declaration and its consequences if

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

                  (A) all overdue installments of interest on the Securities of
            such series,

                  (B) the principal of (and premium, if any, on) any Securities
            of such series which have become due otherwise than by such
            declaration of acceleration, and interest thereon at the rate or
            rates prescribed therefor by the terms of the Securities of such
            series, to the extent that payment of such interest is lawful,

                  (C) interest upon overdue installments of interest at the rate
            or rates prescribed therefor by the terms of the Securities of such
            series to the extent that payment of such interest is

<Page>
                                                                              50


            lawful, and

                  (D) all sums paid or advanced by the Trustee hereunder and the
            reasonable compensation, expenses, disbursements and advances of the
            Trustee, its agents and counsel and all other amounts due the
            Trustee under Section 607; and

            (2) all Events of Default with respect to such series of Securities,
      other than the nonpayment of the principal of the Securities of such
      series which have become due solely by such 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 [and the Guarantor each] covenants that if

            (1) default is made in the payment of any installment of interest on
      any Security of any series when such interest becomes due and payable, or

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

            (3) default is made in the payment of any sinking or purchase fund
      or analogous obligation when the same becomes due by the terms of the
      Securities of any series,

and any such default continues for any period of grace provided with respect to
the Securities of such series, the Company [or the Guarantor, as the case may
be,] will, upon demand of the Trustee, pay to it, for the benefit of the Holder
of any such Security (or the Holders of any such series in the case of Clause
(3) above), the whole amount then due and payable on any such Security (or on
the Securities of any such series in the case of Clause (3) above) for principal
(and premium, if any) and interest, with interest, to the extent that payment of
such interest shall be legally enforceable, upon the overdue principal

<Page>
                                                                              51


(and premium, if any) and upon overdue installments of interest, at such rate or
rates as may be prescribed therefor by the terms of any such Security (or of
Securities of any such series in the case of Clause (3) above); and, in addition
thereto, such further amount as shall be sufficient to cover the costs and
expenses of collection, including the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel and all other
amounts due the Trustee under Section 607.

            If the Company [or the Guarantor] 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, and may prosecute such proceeding to judgment or final
decree, and may enforce the same against the Company [or the Guarantor] or any
other obligor upon the Securities of such series and collect the money adjudged
or decreed to be payable in the manner provided by law out of the property of
the Company [or the Guarantor] or any other obligor upon such Securities,
wherever situated.

            If an Event of Default with respect to any series of Securities
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 the
pendency of any receivership, insolvency, liquidation, bankruptcy,
reorganization, arrangement, adjustment, composition or other judicial
proceeding relative to the Company [, Guarantor] or any other obligor upon the
Securities or the property of the Company [, Guarantor] or of such other obligor
or their creditors, the Trustee (irrespective of whether the principal of the
Securities shall then be due and payable as therein expressed or by declaration
or otherwise and irrespective of

<Page>
                                                                              52


whether the Trustee shall have made any demand on the Company [or the Guarantor]
for the payment of overdue principal or interest) shall be entitled and
empowered, by intervention in such proceedings or otherwise,

            (i) to file and prove a claim for the whole amount of principal (and
      premium, if any) and interest owing and unpaid in respect of the
      Securities and to file such other papers or documents as may be necessary
      and advisable in order to have the claims of the Trustee (including any
      claim for the reasonable compensation, expenses, disbursements and
      advances of the Trustee, its agents and counsel and all other amounts due
      the Trustee under Section 607) and of the Securityholders allowed in such
      judicial proceeding, and

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

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

            Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Securityholder any
plan or 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 Securityholder in any such proceeding.

            Section 505. TRUSTEE MAY ENFORCE CLAIMS WITHOUT POSSESSION OF
SECURITIES. All rights of action and claims under this Indenture or the
Securities of any series may be prosecuted and enforced by the Trustee without
the possession of any of the Securities of such series or the production thereof
in any proceeding relating thereto, and

                                                                              53


any such proceeding instituted by the Trustee shall be brought in its own name
as trustee of an express trust, and any recovery of judgment shall, after
provision for the payment of the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agent and counsel, be for the
ratable benefit of the Holders of the Securities of the series in respect of
which such judgment has been recovered.

            Section 506. APPLICATION OF MONEY COLLECTED. Any money collected 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 on account of principal
(or premium, if any) or interest, upon presentation of the Securities of such
series and the notation thereon of the payment if only partially paid and upon
surrender thereof if fully paid:

            FIRST: To the payment of all amounts due the Trustee under Section
607.

            SECOND: To the payment of the amounts then due and unpaid upon the
Securities of that series 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 Securities for principal (and premium, if any) and
interest, respectively.

            THIRD: To the Company [or the Guarantor or both, as they are
entitled].

            Section 507. LIMITATION ON SUITS. No Holder of any Security of any
series shall have any right to institute any proceeding, judicial or otherwise,
with respect to this Indenture, or for the appointment of a receiver or trustee,
or for any other remedy hereunder, unless

            (1) such Holder has previously given written notice to the Trustee
      of a continuing Event of Default

<Page>
                                                                              54


      with respect to Securities of such series;

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

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

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

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

it being understood and intended that no one or more Holders of Securities of
such series 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 Holders of Securities of such series, or to obtain or to
seek to obtain priority or preference over any other such Holders or to enforce
any right under this Indenture, except in the manner herein provided and for the
equal and proportionate benefit of all the Holders of all Securities of such
series.

            Section 508. UNCONDITIONAL RIGHT OF SECURITY HOLDERS TO RECEIVE
PRINCIPAL, PREMIUM AND INTEREST. Not withstanding any other provisions 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 or
repayment, on the Redemption Date or Repayment Date, as the case may be) and to
institute suit for the enforcement of any such payment, and such right shall not
be impaired without the consent of such Holder.

                                                                              55


            Section 509. RESTORATION OF RIGHTS AND REMEDIES. If the Trustee or
any Securityholder has instituted any proceeding to enforce any right or remedy
under this Indenture and such proceeding has been discontinued or abandoned for
any reason, then and in every such case the Company, [the Guarantor,] the
Trustee and the Securityholders shall, subject to any determination in such
proceeding, be restored severally and respectively to their former positions
hereunder, and thereafter all rights and remedies of the Trustee and the
Securityholders shall continue as though no such proceeding had been instituted.

            Section 510. RIGHTS AND REMEDIES CUMULATIVE. No right or remedy
herein conferred upon or reserved to the Trustee or to the Securityholders 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 Security 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
Securityholders may be exercised from time to time, and as often as may be
deemed expedient, by the Trustee or by the Securityholders, as the case may be.

            Section 512. CONTROL BY SECURITYHOLDERS. The Holders of a majority
in principal amount of the Outstanding Securities of any series shall have the
right to direct the time, method and place of conducting any proceeding for any
remedy available to the Trustee or exercising any trust or power conferred on
the Trustee with respect to the

<Page>
                                                                              56


Securities of such series, provided that

            (1) the Trustee shall have the right to decline to follow any such
      direction if the Trustee, being advised by counsel, determines that the
      action so directed may not lawfully be taken or would conflict with this
      Indenture or if the Trustee in good faith shall, by a Responsible Officer,
      determine that the proceedings so directed would involve it in personal
      liability or be unjustly prejudicial to the Holders not taking part in
      such direction, 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 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 not theretofore cured

            (1) in the payment of the principal of (or premium, if any) or
      interest on any Security of such series, or in the payment of any sinking
      or purchase fund or analogous obligation with respect to the Securities 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.

            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 or

<Page>
                                                                              57


omitted by it as Trustee, the filing by any party litigant in such suit of an
undertaking to pay the costs of such suit, and that such court may in its
discretion assess reasonable costs, including reasonable attorneys' fees,
against any party litigant in such suit, having due regard to the merits and
good faith of the claims or defenses made by such party litigant; but the
provisions of this Section shall not apply to any suit instituted by the
Trustee, to any suit instituted by any Securityholder, or group of
Securityholders, holding in the aggregate more than 10% in principal amount of
the Outstanding Securities of any series to which the suit relates, or to any
suit instituted by any Securityholder 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 or repayment, on or after the Redemption Date or Repayment Date).

            Section 515. WAIVER OF STAY OR EXTENSION LAWS. The Company [and the
Guarantor each] covenants (to the extent that it may lawfully do so) that it
will not at any time insist upon, or plead, or in any manner whatsoever claim or
take the benefit or advantage of, any stay or extension law wherever enacted,
now or at any time hereafter in force, which may affect the covenants or the
performance of this Indenture; and the Company [and the Guarantor each] (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 with respect to any series of Securities,

<Page>
                                                                              58


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

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

            (b) In case an Event of Default with respect to any series of
Securities has occurred and is continuing, the Trustee shall exercise with
respect to the Securities of such series such of the rights and powers vested in
it by this Indenture, and use the same degree of care and skill in their
exercise, as a prudent person would exercise or use under the circumstances in
the conduct of such person's 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

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

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

            (3) 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

<Page>

      Outstanding Securities of any series relating to the time, method and
      place of conducting any proceeding for any remedy available to the
      Trustee, or exercising any trust or power conferred upon the Trustee,
      under this Indenture with respect to the Securities of such series; and

            (4) no provision of this Indenture shall require the Trustee to
      expend or risk its own funds or otherwise incur any financial liability in
      the per formance 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.

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

            Section 602. NOTICE OF DEFAULTS. Within 90 days after the occurrence
of any default hereunder with respect to Securities of any series, the Trustee
shall transmit by mail to all Securityholders of such series, as their names and
addresses appear in the Security Register, notice of such default hereunder
known to the Trustee, unless such default shall have been cured or waived;
PROVIDED, HOWEVER, that, except in the case of a default in the payment of the
principal of (or premium, if any) or interest on any Security of such series or
in the payment of any sinking or purchase fund installment or analogous
obligation with respect to Securities of such series, the Trustee shall be
protected in withholding such notice if and so long as the board of directors,
the executive committee or a trust committee of directors and/or Responsible
Officers of the Trustee in good faith determine that the withholding of such
notice is in the interests of the Securityholders of such series; and PROVIDED,
FURTHER, that in the case of any default of the character specified in Section
501(4) or (5) with respect to Securities of such series no such notice to
Securityholders of such series shall be given until at least

respect to Securities of such series.

            (2) except as otherwise expressly provided herein, to reimburse the
      Trustee upon its request for all reasonable expenses, disbursements and

time provided for therein. In determining whether the Trustee has a conflicting
interest as defined in Section 310(b) of the Trust Indenture Act with respect to
the Securities of any series, there shall be excluded for purposes of the
conflicting interest provisions of such Section 310(b) the Securities of every
other series issued under this Indenture (i) and every series of securities
issued under any other indentures if the requirements for such exclusion set
forth in Section 310(b) of the Trust Indenture Act are met. Nothing herein shall

$50,000,000, and subject to supervision or examination by Federal or State
authority. If such corporation publishes reports of condition at least annually,
pursuant to law or to the requirements of the aforesaid supervising or examining
authority, then for the purposes of this Section, the combined capital and
surplus of such corporation shall be deemed to be its combined capital and
surplus as set forth in its most recent report of condition so published. If at
any time the Trustee with respect to any series of Securities 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 shall become effective until the acceptance of appointment by the
successor Trustee under Section 611.

            (b) The Trustee may resign with respect to any series of Securities
at any time by giving written notice thereof to the Company [and the Guarantor].
If an instrument of acceptance by a successor Trustee shall not have been
delivered to the Trustee within 30 days after the giving of such notice of
removal, the removed Trustee may petition any court of competent jurisdiction
for the appointment of a successor Trustee.

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

giving of such notice of removal, the removed Trustee may petition any court of
competent jurisdiction for the appointment of a successor Trustee.

            (d) If at any time:

            (1) the Trustee shall fail to comply with Section 310(b) of the
      Trust Indenture Act pursuant to Section 608(a) with respect to any series
      of Securities after written request therefor by the Company [, by the
      Guarantor] or by any Securityholder who has been a bona fide Holder of a
      Security of that series for at least 6 months, or

            (2) the Trustee shall cease to be eligible under Section 609 with
      respect to any series of Securities and shall fail to resign after written
      request therefor by the Company [, by the Guarantor] or by any such Se
      curityholder, or

            (3) the Trustee shall become incapable of acting with respect to any
      series of Securities, or

                                                                              65


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

then, in any such case, (i) the Company by a Board Reso lution [, or the
Guarantor by a Guarantor's Board Resolution,] may remove the Trustee, with
respect to the se ries, or in the case of Clause (4), with respect to all
series, or (ii) subject to Section 514, any Securityholder who has been a bona
fide Holder of a Security of such series for at least 6 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 with respect to the series, or, in the case of Clause (4), with respect
to all series.

            (e) If the Trustee shall resign, be removed or become incapable of
acting with respect to any series of Securities, or if a vacancy shall occur in
the office of the Trustee with respect to any series of Securities for any
cause, the Company, by a Board Resolution, shall promptly appoint a successor
Trustee for that series of Securities. If, within one year after such
resignation, removal or incapacity, or the occurrence of such vacancy, a
successor Trustee with respect to such series of Securities 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 [, the Guarantor] and the
retiring Trustee, the successor Trustee so appointed shall, forthwith upon its
acceptance of such appointment, become the successor Trustee with respect to
such series and supersede the successor Trustee appointed by the Company with
respect to such series. If no successor Trustee with respect to such series
shall have been so appointed by the Company or the Securityholders of such
series and accepted appointment in the manner hereinafter provided, any
Securityholder who has been a bona fide Holder of a Security of that series for
at least 6 months may, on behalf of himself and all others similarly situated,
petition any court of competent jurisdiction for the appointment of a successor
Trustee with respect to such series.

            (f) The Company shall give notice of each resignation and each
removal of the Trustee with respect to any series and each appointment of a
successor Trustee with respect to any series by mailing written notice of such
event by first-class mail, postage prepaid, to the Holders of Securities of that
series as their names and addresses appear in the Security Register. Each notice
shall include the name of the successor Trustee and the address of its principal
Corporate Trust Office.

            Section 611. ACCEPTANCE OF APPOINTMENT BY SUCCESSOR. Every successor
Trustee appointed hereunder shall execute, acknowledge and deliver to the
Company [, the Guarantor] and to the predecessor Trustee an instrument accepting
such appointment, and thereupon the resignation or removal of the predecessor
Trustee shall become effective with respect to any series as to which it is
resigning or being removed as Trustee, and such successor Trustee, without any
further act, deed or conveyance, shall become vested with all the rights,
powers, trusts and duties of the predecessor Trustee with respect to any such
series; but, on request of the Company [, the Guarantor] or the successor
Trustee, such predecessor Trustee shall, upon payment of its reasonable charges,
if any, execute and deliver an instrument transferring to such successor Trustee
all the rights, powers and trusts of the predecessor Trustee, and shall duly
assign, transfer and deliver to such successor Trustee all property and money
held by such predecessor Trustee hereunder with respect to all or any such
series, subject nevertheless to its lien, if any, provided for in Section 607.
Upon request of any such successor Trustee, the Company [and the Guarantor]
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.

            In case of the appointment hereunder of a successor Trustee with
respect to the Securities of one or more (but not all) series, the Company, [,
the Guarantor] the predecessor Trustee and each successor Trustee with respect
to the Securities of any applicable series shall

<Page>
                                                                              67


execute and deliver an indenture supplemental hereto which shall contain such
provisions as shall be deemed necessary or desirable to confirm that all the
rights, powers, trusts and duties of the predecessor Trustee with respect to the
Securities of any series as to which the predecessor Trustee is not being
succeeded shall continue to be vested in the predecessor Trustee, and 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.

            No successor Trustee with respect to any series of Securities shall
accept its appointment unless at the time of such acceptance such successor
Trustee shall be qualified and eligible with respect to that series 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 authenticat ing 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. (a)
Subject to Subsection (b) of this Section, if the Trustee shall be or shall
become a creditor, directly or indirectly, secured or unsecured, of the Company
within 3 months prior to a default, as defined in

<Page>
                                                                              68


Subsection (c) of this Section, or subsequent to such a default, then, unless
and until such default shall be cured, the Trustee shall set apart and hold in a
special account for the benefit of the Trustee individually, the Holders of the
Securities and the holders of other indenture securities (as defined in
Subsection (c) of this Section):

            (1) an amount equal to any and all reductions in the amount due and
      owing upon any claim as such creditor in respect of principal or interest,
      effected after the beginning of such 3-month period and valid as against
      the Company and its other creditors, except any such reduction resulting
      from the receipt or disposition of any property described in paragraph (2)
      of this Subsection, or from the exercise of any right of set-off which the
      Trustee could have exercised if a petition in bankruptcy had been filed by
      or against the Company upon the date of such default; and

            (2) all property received by the Trustee in respect of any claim as
      such creditor, either as security therefor, or in satisfaction or
      composition thereof, or otherwise, after the beginning of such 3-month
      period, or an amount equal to the proceeds of any such property, if
      disposed of, subject, however, to the rights, if any, of the Company and
      its other creditors in such property or such proceeds.

Nothing herein contained, however, shall affect the right of the Trustee

                  (A) to retain for its own account (i) payments made on account
            of any such claim by any Person (other than the Company) who is
            liable thereon, and (ii) the proceeds of the bona fide sale of any
            such claim by the Trustee to a third person, and (iii) distributions
            made in cash, securities or other property in respect of claims
            filed against the Company in bankruptcy or receivership or in
            proceedings for reorganization pursuant to the Federal Bankruptcy
            Act or applicable State law;

<Page>
                                                                              69


                  (B) to realize, for its own account, upon any property held by
            it as security for any such claim, if such property was so held
            prior to the beginning of such 3-month period;

                  (C) to realize, for its own account, but only to the extent of
            the claim hereinafter mentioned, upon any property held by it as
            security for any such claim, if such claim was created after the
            beginning of such 3-month period and such property was received as
            security therefor simultaneously with the creation thereof, and if
            the Trustee shall sustain the burden of proving that at the time
            such property was so received the Trustee had no reasonable cause to
            believe that a default as defined in Subsection (c) of this Section
            would occur within 3 months; or

                  (D) to receive payment on any claim referred to in paragraph
            (B) or (C), against the release of any property held as security for
            such claim as provided in paragraph (B) or (C), as the case may be,
            to the extent of the fair value of such property.

            For the purposes of paragraphs (B), (C) and (D), property
substituted after the beginning of such 3-month period for property held as
security at the time of such substitution shall, to the extent of the fair value
of the property released, have the same status as the property released, and, to
the extent that any claim referred to in any of such paragraphs is created in
renewal of or in substitution for or for the purpose of repaying or refunding
any pre-existing claim of the Trustee as such creditor, such claim shall have
the same status as such pre-existing claim.

            If the Trustee shall be required to account, the funds and property
held in such special account and the proceeds thereof shall be apportioned
between the Trustee, the Securityholders and the holders of other indenture
securities in such manner that the Trustee, the Securityholders and the holders
of other indenture secu rities realize, as a result of payments from such
special account and payments of dividends on claims filed

<Page>
                                                                              70


against the Company in bankruptcy or receivership or in proceedings for
reorganization pursuant to the Federal Bankruptcy Act or applicable State law,
the same percentage of their respective claims, figured before crediting to the
claim of the Trustee anything on account of the receipt by it from the Company
of the funds and property in such special account and before crediting to the
respective claims of the Trustee and the Securityholders and the holders of
other indenture securities dividends on claims filed against the Company in
bankruptcy or receivership or in proceedings for reorganization pursuant to the
Federal Bankruptcy Act or applicable State law, but after crediting thereon
receipts on account of the indebtedness represented by their respective claims
from all sources other than from such dividends and from the funds and property
so held in such special account. As used in this paragraph, with respect to any
claim, the term "dividends" shall include any distribution with respect to such
claim, in bankruptcy or receivership or proceedings for reorganization pursuant
to the Federal Bankruptcy Act or applicable State law, whether such distribution
is made in cash, securities, or other property, but shall not include any such
distribution with respect to the secured portion, if any, of such claim. The
court in which such bankruptcy, receivership or proceedings for reorganization
is pending shall have jurisdiction (i) to apportion between the Trustee and the
Securityholders and the holders of other indenture securities in accordance with
the provisions of this paragraph, the funds and property held in such special
account and proceeds thereof, or (ii) in lieu of such apportionment, in whole or
in part, to give to the provisions of this paragraph due consideration in
determining the fairness of the distributions to be made to the Trustee and the
Securityholders and the holders of other indenture securities with respect to
their respective claims, in which event it shall not be necessary to liquidate
or to appraise the value of any securities or other property held in such
special account or as security for any such claim, or to make a specific
allocation of such distributions as between the secured and unsecured portions
of such claims, or otherwise to apply the provisions of this paragraph as a
mathematical formula.

            Any Trustee which has resigned or been removed after the beginning
of such 3-month period shall be subject to the provisions of this Subsection as
though such

<Page>
                                                                              71


resignation or removal had not occurred. If any Trustee has resigned or been
removed prior to the beginning of such 3-month period, it shall be subject to
the provisions of this Subsection if and only if the following conditions exist:

                  (i) the receipt of property or reduction of claim, which would
            have given rise to the obligation to account, if such Trustee had
            continued as Trustee, occurred after the beginning of such 3-month
            period; and

                  (ii) such receipt of property or reduction of claim occurred
            within 3 months after such resignation or removal.

            (b) There shall be excluded from the operation of Subsection (a) of
this Section a creditor relationship arising from

            (1) the ownership or acquisition of securities issued under any
      indenture, or any security or secu rities having a maturity of one year or
      more at the time of acquisition by the Trustee;

            (2) advances authorized by a receivership or bankruptcy court of
      competent jurisdiction, or by this Indenture, for the purpose of
      preserving any property which shall at any time be subject to the lien of
      this Indenture or of discharging tax liens or other prior liens or
      encumbrances thereon, if notice of such advances and of the circumstances
      surrounding the making thereof is given to the Securityholders at the time
      and in the manner provided in this Indenture;

            (3) disbursements made in the ordinary course of business in the
      capacity of trustee under an indenture, transfer agent, registrar,
      custodian, paying agent, fiscal agent or depositary, or other similar
      capacity;

            (4) an indebtedness created as a result of services rendered or
      premises rented; or an indebt edness created as a result of goods or
      securities sold in a cash transaction as defined in Subsection (c) of this
      Section;

<Page>
                                                                              72


            (5) the ownership of stock or of other securities of a corporation
      organized under the provisions of Section 25(a) of the Federal Reserve
      Act, as amended, which is directly or indirectly a creditor of the
      Company; or

            (6) the acquisition, ownership, acceptance or negotiation of any
      drafts, bills of exchange, accep tances or obligations which fall within
      the classi fication of self liquidating paper as defined in Subsection (c)
      of this Section.

            (c) For the purposes of this Section only:

            (1) The term "default" means any failure to make payment in full of
      the principal of or interest on any of the Securities or upon the other
      indenture securities when and as such principal or interest becomes due
      and payable.

            (2) The term "other indenture securities" means securities upon
      which the Company is an obligor outstanding under any other indenture (i)
      under which the Trustee is also trustee, (ii) which contains provisions
      substantially similar to the provisions of this Section, and (iii) under
      which a default exists at the time of the apportionment of the funds and
      property held in such special account.

            (3) The term "cash transaction" means any transaction in which full
      payment for goods or secu rities sold is made within 7 days after delivery
      of the goods or securities in currency or in checks or other orders drawn
      upon banks or bankers and payable upon demand.

            (4) The term "self-liquidating paper" means any draft, bill of
      exchange, acceptance or obligation which is made, drawn, negotiated or

<Page>
                                                                              73


      evidencing title to, possession of, or a lien upon, the goods, wares or
      merchandise or the receivables or proceeds arising from the sale of the
      goods, wares or merchandise previously constituting the security, provided

      of the creditor relationship with the Company arising from the making,
      drawing, negotiating or incurring of the draft, bill of exchange,
      acceptance or obligation.

            (5) The term "Company" means any obligor upon the Securities.

            Section 614. APPOINTMENT OF AUTHENTICATING AGENT. At any time when
any of the Securities remain Outstanding the Trustee, with the approval of the
Company, may appoint an Authenticating Agent or Agents with respect to one or
more series of Securities which shall be authorized to act on behalf of the
Trustee to authenticate Securities of such series issued 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 thereof or the
District of Columbia, authorized under such laws to act as an Authenticating
Agent, having a combined capital and surplus of not less than $50,000,000 and,
if other than the Company itself, subject to supervision or examination by
Federal or State authority. If such Authenticating Agent publishes reports of
condition at least annually, pursuant to law or to the requirements of said
supervising or examining authority, then for the purposes of this Section,

<Page>
                                                                              74


the combined capital and surplus of such Authenticating Agent shall be deemed to
be its combined capital and surplus as set forth in its most recent report of
condition so published. If at any time an Authenticating Agent shall cease to be
eligible in accordance with the provisions of this Section, such Authenticating
Agent shall resign immediately in the manner and with the effect specified in
this Section.

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

            An Authenticating Agent may resign at any time by giving written
notice thereof to the Trustee and, if other than the Company, 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, if other than
the Company, 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,
with the approval of the Company, may appoint a successor Authenticating Agent
which shall be acceptable to the Company and shall mail written notice of such
appointment by first-class mail, postage prepaid, to all Holders of Securities
of the series with respect to which such Authenticating Agent will serve, as
their names and addresses appear in the Security Register. Any successor
Authenticating Agent upon acceptance of its appointment hereunder shall become
vested with all the rights, powers and duties of its predecessor hereunder, with
like effect as if originally named as an Authenticating Agent. No successor
Authenticating Agent shall be appointed unless eligible under the provisions of
this Section.

                                                                              75


            The Trustee agrees to pay to each Authenticating Agent (other than
an Authenticating Agent appointed at the request of the Company from time to
time) reasonable compensation for its services under this Section, and the
Trustee shall be entitled to be reimbursed for such payments, subject to the
provisions of Section 607.

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

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

            (b) at such other times as the Trustee may request in writing,
      within 30 days after the receipt by the Company of any such request, a
      list of similar form and content as of a date not more than 30 days prior
      to the time such list is furnished,

excluding from any such list names and addresses received by the Trustee in its
capacity as Security Registrar.

SECURITYHOLDERS. (a) The Trustee shall preserve, in as current a form as is
reasonably practicable, the names and addresses of Holders of Securities
contained in the most recent list furnished to the Trustee as provided in
Section 701 and the names and addresses of Holders of Securities received by the
Trustee in its capacity as Security Registrar. The Trustee may destroy any list
furnished to it as provided in Section 701 upon receipt of a new list so
furnished.

            (b) If 3 or more Holders of Securities of any series (hereinafter
referred to as "applicants") apply in writing to the Trustee, and furnish to the
Trustee reasonable proof that each such applicant has owned a Security of such
series for a period of at least 6 months preceding the date of such application,
and such application states that the applicants desire to communicate with other
Holders of Securities of such series or with the Holders of all Securities with
respect to their rights under this Indenture or under such Securities and is
accompanied by a copy of the form of proxy or other communication which such
applicants propose to transmit, then the Trustee shall, within 5 Business Days
after the receipt of such application, at its election, either

            (i) afford such applicants access to the information preserved at
      the time by the Trustee in accordance with Section 702(a), or

such information, the Trustee shall, upon the written request of such
applicants, mail to each Holder of a Security of such series or to all Security
holders, as the case may be, whose names and addresses appear in the information
preserved at the time by the Trustee in accordance with Section 702(a), a copy
of the form of proxy or other communication which is specified in such request,
with reasonable promptness after a tender to the Trustee of the material to be
mailed and of payment, or provision for the payment, of the reasonable expenses
of mailing, unless, within 5 days after such tender, the Trustee shall mail to
such applicants and file with the Commission, together with a copy of the
material to be mailed, a written statement to the effect that, in the opinion of
the Trustee, such mailing would be contrary to the best interests of the Holders
of Securities of such series or all Securityholders, as the case may be, or
would be in violation of applicable law. Such written statement shall specify
the basis of such opinion. If the Commission, after opportunity for a hearing
upon the objections specified in the written statement so filed, shall enter an
order refusing to sustain any of such objections or if, after the entry of an
order sustaining one or more of such objections, the Commission shall find,
after notice and opportunity for hearing, that all the objections so sustained
have been met and shall enter an order so declaring, the Trustee shall mail
copies of such material to all Securityholders of such series or all
Securityholders, as the case may be, with reasonable promptness after the entry
of such order and the renewal of such tender; otherwise the Trustee shall be
relieved of any obligation or duty to such applicants respecting their
application.

agrees with the Company and the Trustee

the disclosure of any such information as to the names and addresses of the
Holders of Securities in accordance with Section 702(b), regardless of the
source from which such information was derived, and that the Trustee shall not
be held accountable by reason of mailing any material pursuant to a request made
under Section 702(b).

            Section 703. REPORTS BY TRUSTEE. (a) The term "reporting date" as

      elects so to state, the circumstances surrounding the making thereof) made

      charge, prior to that of Securities of any series, on any property or
      funds held or collected by it as Trustee, except that the Trustee shall
      not be required (but may elect) to report such advances if such advances
      so remaining unpaid aggregate not more than [1%] of the principal amount
      of the Securities of such series outstanding on the date of such report;

            (4) any change to the amount, interest rate and maturity date of all
      other indebtedness owing by the Company (or by any other obligor on the
      Securities) to the Trustee in its individual capacity, on the date of such
      report, with a brief description of any property

      possession of the Trustee as such on the date of such report;

            (6) any additional issue of Securities which the Trustee has not
      previously reported; and

            (7) any action taken by the Trustee in the performance of its duties
      hereunder which it has not previously reported and which in its opinion
      materially affects the Securities, except action in respect of a default,
      notice of which has been or is to be withheld by the Trustee in accordance
      with Section 602.

            (b) The Trustee shall transmit by mail to all Securityholders, as
their names and addresses appear in the Security Register, a brief report with
respect to the character and amount of any advances (and if the Trustee elects
so to state, the circumstances surrounding the making thereof) made by the
Trustee (as such) since the date of the last report transmitted pursuant to
Subsection (a) of this Section (or if no such report has yet been so
transmitted, since the date of execution of this instrument) for the
reimbursement of which it claims or may claim a lien or charge, prior to that of
the Securities of any series, on property or funds held or collected by it as
Trustee, and which it has not previously reported pursuant to this Subsection,
except that the Trustee shall not be required (but may elect) to report such
advances if such advances remaining unpaid at any time aggregate [ ]% or less of
the principal amount of the Securities Outstanding of such series at such time,
such report to be transmitted within 90 days after such time.

            (c) A copy of each such report shall, at the time of such
transmission to Securityholders, be filed by the Trustee with each stock
exchange upon which the Securities

other provision of this Indenture which has expressly been included solely for

covenant or other provision, shall be deemed not to affect the rights under this
Indenture of the Holders of Securities of any other series.

            It shall not be necessary for any Act of Securityholders 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.

indenture entered into under Section 901(4) or 901(6)) be obligated to, enter
into any such supplemental indenture which affects the Trustee's own rights,
duties or immunities under this Indenture or otherwise.

            Section 904. EFFECT OF SUPPLEMENTAL INDENTURES. Upon the execution
of any supplemental indenture under this Article, this Indenture shall be

maintain an office or agency in each Place of Payment where Securities may be
presented or surrendered for payment, where Securities may be surrendered for
transfer or exchange and where notices and demands to or upon the Company in

            Section 1003. MONEY FOR SECURITY PAYMENTS TO BE HELD IN TRUST. If
the Company shall at any time act as its own Paying Agent for any series of
Securities, it will, on or before each due date of the principal of (and
premium, if any) or interest on, any of the Securities of such series, segregate
and hold in trust for the benefit of the Persons entitled thereto a sum
sufficient to pay the principal (and

<Page>
                                                                              89


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

            Whenever the Company shall have one or more Paying Agents for any
series of Securities, it will, on or prior to each due date of the principal of

Persons entitled to such principal (and premium, if any) or interest, 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 for
any series of Securities to execute and deliver to the Trustee an instrument in
which such Paying Agent shall agree with the Trustee, subject to the provisions
of this Section, that such Paying Agent will

            (1) hold all sums held by it for the payment of principal of (and
      premium, if any) or interest on Securities of such series in trust for the
      benefit of the Persons entitled thereto until such sums shall be paid to
      such Persons or otherwise disposed of as herein provided;

            (2) give the Trustee notice of any default by the Company (or any
      other obligor upon the Securities of such series) in the making of any
      such payment of principal (and premium, if any) or interest on the
      Securities of such series; 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 [or the Guarantor] may at any time, for the purpose of
obtaining the satisfaction and discharge of this Indenture with respect to any
series of Securities or for any other purpose, pay, or by Company Order [or the

                                       90


Guarantor Order] direct any Paying Agent to pay, to the Trustee all sums held in
trust by the Company [, the Guarantor] or such Paying Agent in respect of each
and every series of Securities as to which it seeks to discharge this Indenture
or, if for any other purpose, all sums so held in trust by the Company [or the
Guarantor] in respect of all Securities, such sums to be held by the Trustee
upon the same trusts as those upon which such sums were held by the Company [,
the Guarantor] or such Paying Agent; and, upon such payment by any Paying Agent
to the Trustee, such Paying Agent shall be released from all further liability
with respect to such money.

            Any money deposited with the Trustee or any Paying Agent, or then
held by the Company [or the Guarantor], in trust for the payment of the
principal of (and premium, if any) or interest on any Security of any series and
remaining unclaimed for two years after such principal (and premium, if any) or
interest has become due and payable shall be paid to the Company on Company
Request [(or, if deposited by the Guarantor, paid to the Guarantor upon
Guarantor Request)], or (if then held by the Company [or the Guarantor]) shall
be discharged from such trust; and the Holder of such Security shall thereafter,
as an unsecured general creditor, look only to the Company [and the Guarantor]
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. The Trustee or such Paying Agent, before being
required to make any such repayment, may at the expense of the Company [and the
Guarantor] mail to the Holders of the Securities as to which the money to be
repaid was held in trust, as their names and addresses appear in the Security
Register, a notice that such moneys remain unclaimed and that, after a date
specified in the notice, which shall not be less than [30] days from the date on
which the notice was first mailed to the Holders of the Securities as to which
the money to be repaid was held in trust, any unclaimed balance of such moneys
then remaining will be paid to the Company [or the Guarantor, as the case may
be,] free of the trust formerly impressed upon it.

            The Company initially authorizes the Trustee to act as Paying Agent
for the Securities on its behalf. The Company may at any time and from time to
time authorize one or more Persons to act as Paying Agent in addition to or in
place of the Trustee with respect to any series of Securities issued under this
Indenture.

            Section 1004. STATEMENT AS TO COMPLIANCE. The Company [and the
Guarantor each] will deliver to the Trustee, within [120] days after the end of
each fiscal year, a written statement signed by the principal executive officer,
principal financial officer or principal accounting officer of the Company [or
the Guarantor, as the case may be], stating that

            (1) a review of the activities of the Company [or the Guarantor, as
      the case may be,] during such year and of its performance under this
      Indenture and under the terms of the Securities has been made under his
      supervision; and

            (2) to the best of his knowledge, based on such review, the Company
      [or the Guarantor, as the case may be,] has complied with all conditions
      and covenants under this Indenture through such year, or, if there has
      been a default in the fulfillment of any such obligation, specifying each
      such default known to him and the nature and status thereof.

            For purposes of this Section 1004, compliance shall be determined
without regard to any grace period or requirement of notice provided pursuant to
the terms of this Indenture.

            Section 1005. CORPORATE EXISTENCE. Subject to Article Eight [each
of] the Company [and the Guarantor] will do or cause to be done all things
necessary to preserve and keep in full force and effect its corporate existence.

Company may reserve the right to redeem and pay before Stated Maturity all or
any part of the Securities of any series, either by optional redemption, sinking
or purchase fund or analogous obligation or otherwise, by provision therefor in
the form of Security for such series established and approved pursuant to
Section 202 and on such terms as are specified in such form or in the Board
Resolution or indenture supplemental hereto with respect to Securities of such
series as provided in Section 301. Redemption of Securities of any series shall
be made in accordance with the terms of such Securities and, to the extent that
this Article does not conflict with such terms, the succeeding Sections of this
Article.

            Section 1102. ELECTION TO REDEEM; NOTICE TO TRUSTEE. The election of
the Company to redeem any Securities redeemable at the election of the Company
shall be evidenced by, or made pursuant to authority granted by, a Board
Resolution. In case of any redemption at the election of the Company of any
Securities of any series, the Company shall, at least 60 days prior to the
Redemption Date fixed by the Company (unless a shorter notice shall be
satisfactory to the Trustee), notify the Trustee of such Redemption Date and of
the principal amount of Securities of such series to be redeemed.

            In the case of any redemption of Securities (i) prior to the
expiration of any restriction on such redemption provided in the terms of such
Securities or elsewhere in this Indenture, or (ii) pursuant to an election of
the Company which is subject to a condition specified in the terms of such
Securities, the Company shall furnish the Trustee with an Officers' Certificate
evidencing compliance with such restriction or condition.

            Section 1103. SELECTION BY TRUSTEE OF SECURITIES TO BE REDEEMED. If
less than all the Securities of like tenor and terms of any series are to be
redeemed, the particular Securities to be redeemed shall be selected not more
than 60 days prior to the Redemption Date by the Trustee, from the Outstanding
Securities of such series not previously called for redemption, by such method
as the

<Page>
                                                                              93


Trustee shall deem fair and appropriate and which may include provision for the
selection for redemption of portions of the principal of Securities of such
series of a denomination larger than the minimum authorized denomination for
Securities of that series. Unless otherwise provided in the terms of a
particular series of Securities, the portions of the principal of Securities so
selected for partial redemption shall be equal to the minimum authorized
denomination of the Securities of such series, or an integral multiple thereof,
and the principal amount which remains outstanding shall not be less than the
minimum authorized denomination for Securities of such series. If less than all
the Securities of unlike tenor and terms of a series are to be redeemed, the
particular Securities to be redeemed shall be selected by the Company.

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

            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 Security redeemed or to be redeemed only in part, to the
portion of the principal of such Security which has been or is to be redeemed.

            Section 1104. NOTICE OF REDEMPTION. Notice of redemption shall be
given by first-class mail, postage prepaid, mailed not less than 30 nor more
than 60 days prior to the Redemption Date, to each holder of Securities to be
redeemed, at his address appearing in the Security Register.

            All notices of redemption shall state:

            (1) the Redemption Date;

            (2) the Redemption Price;

            (3) if less than all Outstanding Securities of any series are to be
      redeemed, the identification,

<Page>
                                                                              94


      including CUSIP Numbers (and, in the case of partial redemption, the
      respective principal amounts) of the Securities to be redeemed, from the
      Holder to whom the notice is given;

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

            (5) the place where such Securities are to be surrendered for
      payment of the Redemption Price, which shall be the office or agency of
      the Company in the Place of Payment; and

            (6) that the redemption is on account of a sinking or purchase fund,
      or other analogous obligation, if that be the case.

            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. Such notice shall be
deemed to have been given to each Holder if sent in accordance with Section 105
hereof.

            Section 1105. DEPOSIT OF REDEMPTION PRICE. On or prior to 10:00 a.m.
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 all the Securities which are to be redeemed on that
date.

            Section 1106. SECURITIES PAYABLE ON REDEMPTION DATE. Notice of
Redemption having been given as aforesaid, the Securities so to be redeemed
shall, on the Redemption Date, become due and payable at the Redemption Price
therein specified and from and after such date (unless the Company shall default
in the payment of the Redemption Price) such Securities shall cease to bear
interest. Upon surrender of such Securities for redemption in accordance with
the notice, such Securities shall be paid by the Company at the Redemption
Price. Installments of interest the Stated Maturity of which is on or prior to
the Redemption Date

<Page>
                                                                              95


shall be payable to the Holders of such Securities registered as such 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 shall, until paid, bear interest
from the Redemption Date at the rate borne by the Security, or as otherwise
provided in such Security.

            Section 1107. SECURITIES REDEEMED IN PART. Any Security which is to
be redeemed only in part shall be surrendered at the office or agency of the
Company in the Place of Payment with respect to that series (with, if the
Company or the Trustee so requires, due endorsement by, or a written instrument
of transfer in form satisfactory to the Company and the Trustee duly executed
by, the Holder thereof or his attorney duly authorized in writing) and the
Company shall execute and the Trustee shall authenticate and deliver to the
Holder of such Security without service charge, a new Security or Securities of
the same series and Stated Maturity and of like tenor and terms, 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.

            Section 1108. PROVISIONS WITH RESPECT TO ANY SINKING FUNDS. Unless
the form or terms of any series of Securities shall provide otherwise, in lieu
of making all or any part of any mandatory sinking fund payment with respect to
such series of Securities in cash, the Company may at its option (1) deliver to
the Trustee for cancellation any Securities of such series theretofore acquired
by the Company, or (2) receive credit for any Securities of such series (not
previously so credited) acquired by the Company and theretofore delivered to the
Trustee for cancellation or redeemed by the Company other than through the
mandatory sinking fund, and if it does so then (i) Securities so delivered or
credited shall be credited at the applicable sinking fund Redemption Price with
respect to Securities of such series, and (ii) on or before the 60th day next
preceding each sinking fund Redemption Date with respect to

<Page>
                                                                              96


such series of Securities, the Company will deliver to the Trustee (A) an
Officers' Certificate specifying the portions of such sinking fund payment to be
satisfied by payment of cash and by delivery or credit of Securities of such
series acquired by the Company or so redeemed, and (B) such Securities so
acquired, to the extent not previously surrendered. Such Officers' Certificate
shall also state the basis for such credit and that the Securities for which the
Company elects to receive credit have not been previously so credited and were
not redeemed by the Company through operation of the mandatory sinking fund, if
any, provided with respect to such Securities and shall also state that no Event
of Default with respect to Securities of such series has occurred and is
continuing. All Securities so delivered to the Trustee shall be canceled by the
Trustee and no Securities shall be authenticated in lieu thereof.

            If the sinking fund payment or payments (mandatory or optional) with
respect to any series of Securities made in cash plus any unused balance of any
preceding sinking fund payments with respect to Securities of such series made
in cash shall exceed $50,000 (or a lesser sum if the Company shall so request),
unless otherwise provided by the terms of such series of Securities, that cash
shall be applied by the Trustee on the sinking fund Redemption Date with respect
to Securities of such series next following the date of such payment to the
redemption of Securities of such series at the applicable sinking fund
Redemption Price with respect to Securities of such series, together with
accrued interest, if any, to the date fixed for redemption, with the effect
provided in Section 1106. The Trustee shall select, in the manner provided in
Section 1103, for redemption on such sinking fund Redemption Date a sufficient
principal amount of Securities of such series to utilize that cash and shall
thereupon cause notice of redemption of the Securities of such series for the
sinking fund to be given in the manner provided in Section 1104 (and with the
effect provided in Section 1106) for the redemption of Securities in part at the
option of the Company. Any sinking fund moneys not so applied or allocated by
the Trustee to the redemption of Securities of such series shall be added to the
next cash sinking fund payment with respect to Securities of such series
received by the Trustee and, together with such payment, shall be applied in
accordance with the provisions of this Section 1108. Any and all sinking fund
moneys with

                                                                              97


respect to Securities of any series held by the Trustee at the Maturity of
Securities of such series, and not held for the payment or redemption of
particular Securities of such series, shall be applied by the Trustee, together
with other moneys, if necessary, to be deposited sufficient for the purpose, to
the payment of the principal of the Securities of such series at Maturity.

            On or before each sinking fund Redemption Date provided with respect
to Securities of any series, the Company shall pay to the Trustee in cash a sum
equal to all accrued interest, if any, to the date fixed for redemption on
Securities to be redeemed on such sinking fund Redemption Date pursuant to this
Section 1108.

                                  SUBORDINATION

            Section 1201. AGREEMENT OF SECURITYHOLDERS THAT SECURITIES
SUBORDINATED TO EXTENT PROVIDED. The Company, for itself, its successors and
assigns, covenants and agrees and each Holder of the Securities by his or her
acceptance thereof likewise covenants and agrees that the payment of the
principal of, premium, if any, and interest on each and all of the Securities is
hereby expressly subordinated, to the extent and in the manner hereinafter set
forth, to the prior payment in full of all Senior Indebtedness. The provisions
of this Article shall constitute a continuing offer to all persons who, in
reliance upon such provisions, become holders of, or continue to hold, Senior
Indebtedness, and such provisions are made for the benefit of the holders of
Senior Indebtedness, and such holders are hereby made obligees hereunder the
same as if their names were written herein as such, and the and/or each of them
may proceed to enforce such provisions.

            Section 1202. COMPANY NOT TO MAKE PAYMENTS WITH RESPECT TO
SECURITIES IN CERTAIN CIRCUMSTANCES. (a) Upon the maturity of any Senior
Indebtedness by lapse of time, acceleration or otherwise, all principal thereof
and premium, if any, and interest thereon shall first be paid in

<Page>
                                                                              98


full, or such payment duly provided for in cash or in a manner satisfactory to
the holder or holders of such Senior Indebtedness, before any payment is made on
account of the principal of or premium, if any, or interest on the Securities or
to acquire any of the Securities or on account of any sinking fund (except
sinking fund payments made in Securities acquired by the Company before the
maturity of such Senior Indebtedness).

            (b) Upon the happening of (i) an event of default with respect to
any Senior Indebtedness, as such event of default is defined therein or in the
instrument under which it is outstanding, permitting the holders to accelerate
the maturity thereof, or (ii) an event which, with the giving of notice, or
lapse of time, or both, would constitute such an event of default, then, unless
and until such event shall have been cured or waived or shall have ceased to
exist, no payment shall be made by the Company with respect to the principal of
or premium, if any, or interest on the Securities or to acquire any of the
Securities or on account of any sinking fund for the Securities (except sinking
fund payments made in Securities acquired by the Company before such default and
notice thereof).

            (c) In the event that notwithstanding the provisions of this Section
1202 the Company shall make any payment to the Trustee on account of the
principal of or premium, if any, or interest on the Securities, or on account of
any sinking fund, or the Holders of the Securities shall receive any such
payment, after the happening of a default in payment of the principal of or
premium, if any, or interest on Senior Indebtedness, then, unless and until such
default or event of default shall have been cured or waived or shall have ceased
to exist, such payment (subject to the provisions of Section 1206) shall be held
by the Trustee or the Holders of the Securities, as the case may be, in trust
for the benefit of, and shall be paid forthwith over and delivered to, the
holders of Senior Indebtedness (pro rata as to each of such holders on the basis
of the respective amounts of Senior Indebtedness held by them) or their
representatives or the trustee under the indenture or other agreement (if any)
pursuant to which any instruments evidencing any Senior Indebtedness may have
been issued, as their respective interests may appear, for application to the
payment of all Senior Indebtedness

<Page>
                                                                              99


remaining unpaid to the extent necessary to pay all Senior Indebtedness in full
in accordance with the terms of such Senior Indebtedness, after giving effect to
any concurrent payment or distribution to or for the holders of Senior
Indebtedness. The Company shall give prompt written notice to the Trustee of any
default under any Senior Indebtedness or under any agreement pursuant to which
Senior Indebtedness may have been issued.

            Section 1203. SECURITIES SUBORDINATED TO PRIOR PAYMENTS OF ALL
SENIOR INDEBTEDNESS ON DISSOLUTION, LIQUIDATION OR REORGANIZATION OF THE
COMPANY. Upon any distribution of assets of the Company upon any dissolution,
winding up, liquidation or reorganization of the Company (whether in bankruptcy,
insolvency or receivership proceedings or upon an assignment for the benefit of
creditors or otherwise):

            (a) the holders of all Senior Indebtedness shall first be entitled
      to receive payment in full of the principal thereof, premium, if any, and
      interest due thereon before the Holders of the Securities are entitled to
      receive any payment on account of the principal of, premium, if any, or
      interest on the Securities;

            (b) any payment or distribution of assets of the Company of any kind
      or character, whether in cash, property or securities, to which the
      Holders of the Securities or the Trustees would be entitled except for the
      provisions of this Article Twelve, shall be paid by the liquidating
      trustee or agent or other person making such payment or distribution,
      whether a trustee in bankruptcy, a receiver or liquidating trustee or
      other trustee or agent, directly to the holders of Senior Indebtedness or
      their representative or representatives, or to the trustee or trustees
      under any indenture under which any instruments evidencing any of such
      Senior Indebtedness may have been issued, to the extent necessary to make
      payment in full of all Senior Indebtedness remaining unpaid, after giving
      effect to any concurrent payment or distribution or

      provision therefor to the holders of such Senior Indebtedness;

            (c) in the event that notwithstanding the foregoing provisions of
      this Section 1203, any payment or distribution of assets of the Company of
      any kind or character, whether in cash, property or securities, shall be
      received by the Trustee or the Holders of the Securities on account of
      principal, or premium, if any, or interest on the Securities before all
      Senior Indebtedness is paid in full, or effective provisions made for its
      payment, such payment or distribution (subject to the provisions of
      Sections 1206 and 1207) shall be received and held in trust for and shall
      be paid over to the holders of the Senior Indebtedness remaining unpaid or
      unprovided for or their representative or representatives, or to the
      trustee or trustees under any indenture under which any instruments
      evidencing any of such Senior Indebtedness may have been issued, for
      application to the payment of such Senior Indebtedness until all such
      Senior Indebtedness shall have been paid in full, after giving effect to
      any concurrent payment or distribution or provision therefor to the
      holders of such Senior Indebtedness.

            Section 1204. SECURITYHOLDERS TO BE SUBROGATED TO RIGHT OF HOLDERS
OF SENIOR INDEBTEDNESS. Subject to the payment in full of all Senior
Indebtedness, the Holders of the Securities shall be subrogated to the rights of
the holders of Senior Indebtedness to receive payments or distributions of
assets of the Company applicable to the Senior Indebtedness until all amounts
owing on the Securities shall be paid in full, and for the purpose of such
subrogation no payments or distributions to the holders of the Senior
Indebtedness by or on behalf of the Company or by or on behalf of the Holders of
the Securities by virtue of this Article which otherwise would have been made to
the Holders of the Securities, be deemed to be payment by the Company to or on
account of the Senior Indebtedness, it being understood that the provisions of
this Article Twelve are and are intended solely for the purpose of defining the
relative rights of the Holders of the Securities, on the one hand, and the
holders of the Senior Indebtedness, on the other hand.

                                                                             101


            Section 1205. OBLIGATION OF THE COMPANY UNCONDITIONAL. Nothing
contained in this Article Twelve or elsewhere in this Indenture or in the
Securities is intended to or shall impair as between the Company and the Holders
of the Securities, the obligations of the Company, which is absolute and
unconditional, to pay to the Holders of the Securities the principal of,
premium, if any, and interest on the Securities as and when the same shall
become due and payable in accordance with their terms, or is intended to or
shall affect the relative rights of the Holders of the Securities and creditors
of the Company other than the holders of the Senior Indebtedness, nor shall
anything herein or therein prevent the Trustee or the Holder of any Security
from exercising all remedies otherwise permitted by applicable law upon default
under this Indenture subject to the rights, if any, under this Article Twelve of
the holders of Senior Indebtedness in respect of cash, property or securities of
the Company received upon the exercise of any such remedy. Upon any distribution
of assets of the Company referred to in this Article Twelve, the Trustee,
subject to the provisions of Section 601, and the Holders of the Securities
shall be entitled to rely upon any order or decree made by any court of
competent jurisdiction in which such dissolution, winding up, liquidation or
reorganization proceedings are pending, or a certificate of the liquidating
trustee or agent or other person making any distribution to the Trustee or to
the Holders of the Securities, for the purpose of ascertaining the persons
entitled to participate in such distribution, the holders of the Senior
Indebtedness and other indebtedness of the Company, the amount thereof or
payable thereon, the amount or amounts paid or distributed thereon and all other
facts pertinent thereto or to this Article Twelve.

            Section 1206. TRUSTEE ENTITLED TO ASSUME PAYMENTS NOT PROHIBITED IN
ABSENCE OF NOTICE. The Trustee shall not at any time be charged with knowledge
of the existence of any facts which would prohibit the making of any payment of
monies to or by the Trustee, unless and until a Responsible Officer of the
Trustee shall have received written notice thereof from the Company or from one
or more holders of

<Page>
                                                                             102


Senior Indebtedness or from any trustee therefor; and, prior to the receipt of
any such written notice, the Trustee, subject to the provisions of Section 601,
shall be entitled to assume conclusively that no such facts exist.

            Section 1207. APPLICATION BY TRUSTEE OF MONIES DEPOSITED WITH IT.
Anything in this Indenture to the contrary notwithstanding, any deposit of
monies by the Company with the Trustee or any paying agent (whether or not in
trust) for the payment of the principal of or premium, if any, or interest on
any Securities shall be subject to the provisions of Sections 1201, 1202, 1203
and 1204 except that, if prior to the date on which by the terms of this
Indenture any such monies may become payable for any purpose (including, without
limitation, the payment of either the principal of or interest or premium, if
any, on any Security) a Responsible Officer of the Trustee shall not have
received with respect to such monies the notice provided for in Section 1206,
then, anything herein contained to the contrary notwithstanding, the Trustee
shall have full power and authority to receive such monies and to apply the same
to the purpose for which they were received, and shall not be affected by any
notice to the contrary which may be received by it on or after such date.

            Section 1208. SUBORDINATION RIGHTS NOT IMPAIRED BY ACTS OR OMISSIONS
OF COMPANY OR HOLDERS OF SENIOR INDEBTEDNESS. No right of any present or future
holders of any Senior Indebtedness to enforce subordination as herein provided
shall at any time in any way be prejudiced or impaired by any act or failure to
act on the part of the Company or by any act or failure to act, in good faith,
by any such holder, or by any noncompliance by the Company with the terms,
provisions and covenants of this Indenture, regardless of any knowledge thereof
which any such holder may have or be otherwise charged with.

            Section 1209. SECURITYHOLDERS AUTHORIZE TRUSTEE TO EFFECTUATE
SUBORDINATION OF SECURITIES. Each Holder of the Securities by his or her
acceptance thereof authorizes and expressly directs the Trustee on his or her
behalf to take such action as may be necessary or appropriate to effectuate the
subordination provided in this Article Twelve and appoints the Trustee his/her
attorney-in-fact for such purpose, including, in the event of any dissolution,
winding

insolvency or receivership proceedings or upon an assignment for the benefit of
creditors or otherwise) tending towards liquidation of the business and assets
of the Company, the immediate filing of a claim for the unpaid balance of its or
his or her Securities in the form required in said proceedings and cause said
claim to be approved. If the trustee does not file a proper claim or proof of
debt in the form required in such proceeding prior to 30 days before the
expiration of the time to file such claim or claims, then the holder or holders
of the Senior Indebtedness are hereby authorized to and have the right to file
an appropriate claim for and on behalf of the holders of said Securities.

            Section 1210. RIGHT OF TRUSTEE TO HOLD SENIOR INDEBTEDNESS. The
Trustee shall be entitled to all of the rights set forth in this Article Twelve
in respect of any Senior Indebtedness at any time held by it to the same extent
as any other holder of Senior Indebtedness, and nothing in Section 613 or
elsewhere in this Indenture shall be construed to deprive the Trustee of any of
its rights as such holder.

            Section 1211. ARTICLE TWELVE NOT TO PREVENT EVENTS OF DEFAULT. The
failure to make a payment on account of principal, interest or sinking fund by
reason of any provision of this Article Twelve shall not be construed as
preventing the occurrence of an Event of Default under Section 501.

                               [ARTICLE THIRTEEN]

                            [GUARANTEE OF SECURITIES]

            [SECTION 1301. GUARANTEE. The Guarantor hereby fully and
unconditionally guarantees to each Holder of a Security of each series issued by
the Company, authenticated and delivered by the Trustee, the due and punctual
payment of the principal (including any amount due in respect of any Original
Issue Discount Security) of and any premium and

                                                                             104


interest on such Security, and the due and punctual payment of any sinking fund
payments provided for pursuant to the terms of such Security, when and as the
same shall become due and payable, whether at the Stated Maturity, by
declaration of acceleration, call for redemption, early repayment or otherwise,
in accordance with the terms of such Security and this Indenture. The Guarantor
hereby agrees that in the event of an Event of Default its obligations hereunder
shall be as if it were a principal debtor and not merely a surety, and shall be
absolute and unconditional, irrespective of, and shall be unaffected by, any
invalidity, irregularity or unenforceability of any Security of any series or
this Indenture, any failure to enforce the provisions of any Security of any
series or this Indenture, any waiver, modification or indulgence granted to the
Company with respect thereto by the Holder of any Security of any series or the
Trustee, or any other circumstances which may otherwise constitute a legal or
equitable discharge of a surety or guarantor; provided, however, that,
notwithstanding the foregoing, no such waiver, modification or indulgence shall,
without the consent of the Guarantor, increase the principal amount of any
Security or the interest rate thereon or increase any premium payable upon
redemption thereof. The Guarantor hereby waives diligence, presentment, demand
of payment, filing of claims with a court in the event of merger or bankruptcy
of the Company, any right to require a proceeding first against the Company, the
benefit of discussion, protest or notice with respect to any Security or the
indebtedness evidenced thereby or with respect to any sinking fund payment
required pursuant to the terms of such Security issued under this Indenture and
all demands whatsoever, and covenants that this Guarantee will not be discharged
with respect to such Security except by payment in full of the principal thereof
and any premium and interest thereon or as provided in Article Four or Section
802. If any Holder or the Trustee is required by any court or otherwise to
return to the Company, the Guarantor, or any custodian, trustee, liquidator or
other similar official acting in relation to the Company or the Guarantor any
amount paid by the Company or the Guarantor to the Trustee or such Holder, this
Guarantee to the extent theretofore discharged, shall be reinstated in full
force and effect. The Guarantor further agrees that, as between the Guarantor,
on the one hand, and the Holders and the Trustee, on the other hand, the
Maturity of the obligations guaranteed

                                                                             105


hereby may be accelerated as provided in Article Five hereof for the purposes of
this Guarantee, notwithstanding any stay, injunction or other prohibition
preventing such acceleration in respect of the obligations guaranteed hereby.

            The Guarantor also agrees, to pay any and all reasonable costs and
expenses (including reasonable attorneys' fees and expenses) incurred by the
Trustee or any Holders in enforcing any rights under this Guarantee.

            The Guarantor hereby waives any right of set off which the Guarantor
may have against the Holder of any Security in respect of any amounts which are
or may become payable by such Holder to the Company.

            The Guarantor shall be subrogated to all rights of the Holders of
any series of Securities and the Trustee against the Company in respect of any
amounts paid to such Holders and the Trustee by the Guarantor pursuant to the
provisions of the Guarantee; provided, however, that the Guarantor shall not be
entitled to enforce or to receive any payments arising out of or based upon,
such right of subrogation until the principal of, premium, if any, and interest,
if any, on all of the Securities of such series shall have been paid in full.

            No past, present or future stockholder, officer, director, employee
or incorporator of the Guarantor shall have any personal liability under the
Guarantees set forth in this Section 1301 by reason of his, her or its status as
such stockholder, officer, director, employee or incorporator.

            The Guarantee set forth in this Section 1301 shall not be valid or
become obligatory for any purpose with respect to any Security until the
certificate of authentication on such Security shall have been signed by or on
behalf of the Trustee.]

            [SECTION 1302. SUBORDINATION OF GUARANTEE. The obligation of the
Guarantor under the Guarantee pursuant to

<Page>
                                                                             106


this Article 13 shall be junior and subordinated to Senior Indebtedness of the
Guarantor on the same basis as the Securities are junior and subordinated to
Senior Indebtedness of the Company. For purposes of the foregoing sentence, the
Trustee and the Holders shall have the right to receive and/or retain payments
by the Guarantor only at such times as them may receive and/or retain payments
in respect of the Securities pursuant to this Indenture, including Article 12
hereof. The Guarantee made by the Guarantor hereunder and evidenced by any
notation of Guarantee endorsed on any Security is subject to the provisions of
Article 12 hereof.]

            [SECTION 1303. EXECUTION OF NOTATIONS OF GUARANTEE. To evidence its
Guarantee to the Holders specified in Section 1301, the Guarantor hereby agrees
to execute the notation of the Guarantee in substantially the form set forth in
Section 205 to be endorsed on each Security authenticated and delivered by the
Trustee. The Guarantor hereby agrees that its Guarantee set forth in Section
1301 shall remain in full force and effect notwithstanding any failure to
endorse on any Security a notation of such Guarantee. Each such notation of
Guarantee shall be signed on behalf of the Guarantor by any proper officer of
the Guarantor prior to the authentication of the Security on which it is
endorsed, and the delivery of such Security by the Trustee, after the due
authentication thereof by the Trustee hereunder, shall constitute due delivery
of the Guarantee on behalf of the Guarantor. Such signatures upon the notation
of the Guarantee may be manual or facsimile signatures of any present, past or
future proper officer of the Guarantor and may be imprinted or otherwise
reproduced below the notation of the Guarantee, and in case any such proper
officer of the Guarantor who shall have signed the notation of the Guarantee
shall cease to be such officer before the Security on which such notation is
endorsed shall have been authenticated and delivered by the Trustee or disposed
of by the Company, such Security nevertheless may be authenticated and delivered
or disposed of as though the person who signed the notation of the Guarantee had
not ceased to be such officer of the Guarantor.]]
