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.

instrument or writing may be proved by 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

<Page>

                                                                              15

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, direction, notice, consent,
waiver or other action by the Holder of any Security shall bind the Holder of
every 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.

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 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

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 accordance 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 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.

          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

<Page>

                                                                              21

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.

          (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

<Page>

                                                                              22

       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.

          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. The signature
of any of these officers on the Securities may be manual or facsimile.

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

          At any time and from time to time after the execution and delivery of
this Indenture, the Company may deliver Securities executed by the Company to
the Trustee for authentication; 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;

          (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

<Page>

                                                                              29

     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, 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 corporate 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, 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).

          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

<Page>

                                                                              30

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 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 benefits 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

<Page>

                                                                              31

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 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.

<Page>

                                                                              32

          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 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.

<Page>

                                                                              33

          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 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

<Page>

                                                                              34

     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
     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 the 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 the 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.

                                                                              35

          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.

          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 surrendered 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

                                                                              36

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 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

<Page>

                                                                              37

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" 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>

                                                                              38

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.

                    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 U.S. 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 currency other
than U.S. dollars may be specified pursuant to Section 301.

          Section 402.  SATISFACTION AND DISCHARGE OF INDENTURE; DEFEASANCE. (a)
If at any time (i) the Company or the Guarantor 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 or the
Guarantor 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 interest due or to become due on such date of
maturity or redemption date, as

                                                                              40

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 or the Guarantor 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
or the Guarantor shall also pay or cause to be paid all other sums payable
hereunder by the Company or the Guarantor, 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 or the Guarantor, 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 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 with
respect to the Securities of such series under Section 1006 and 1007 and, to the
extent specified pursuant to Section 301, any other covenant applicable to the
Securities of such series ("covenant defeasance option"). The Company or the
Guarantor may exercise its legal defeasance option notwithstanding the prior
exercise of the 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 specified in
Section 501(4) or (5) to the extent it relates to Section 1006 or 1007.

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

          (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

<Page>

                                                                              42

     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.

          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

                                                                              43

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 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

                                    REMEDIES

          liability company organized and existing under the laws of the United
          States of America, any State thereof, the District of Columbia or
          Bermuda, and shall expressly assume, by an indenture supplemental
          hereto, executed by the successor Person and the Company and delivered
          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

                                                                              47

          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), (8) (if the Event of Default under paragraph (4), (5) or (8)
is with respect to all series of Securities then Outstanding), (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 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 declare 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, if any, 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 acceleration 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

<Page>

                                                                              48

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 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

<Page>

                                                                              49

          (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 (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.

                                                                              50

          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 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

<Page>

                                                                              51

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 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

                                                                              52

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 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 aggregate 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 SECURITYHOLDERS TO RECEIVE
PRINCIPAL, PREMIUM AND INTEREST. Notwithstanding 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.

          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.

                                                                              54

          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 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.

                                                                              55

          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 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>

                                                                              56

          (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 Outstanding
     Securities of any series relating to the time, method and place of
     conducting any proceeding

<Page>

                                                                              57

     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 performance of any of its duties hereunder, or in the exercise of any
     of its rights or powers, if it shall have reasonable grounds for believing
     that repayment of such funds or adequate indemnity against such risk or
     liability is not reasonably assured to it.

          (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 90 days after the
occurrence thereof. For the purpose of this Section, the term "default", with
respect to Securities of any series, means any event which is, or after notice
or lapse of time or both would become, an Event of Default with respect to
Securities of such series.

rely upon an Officers' Certificate;

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

          (e)  the Trustee shall be under no obligation to exercise any of the
rights or powers vested in it by this Indenture at the request or direction of
any of the Securityholders pursuant to this Indenture, unless such

indemnity against the costs, expenses and liabilities which might be incurred by
it in compliance with such request or direction;

debenture or other paper or document, but the Trustee, in its discretion, may
make such further inquiry or investigation into such facts or matters as it may
see fit, and, if the Trustee shall determine to make such further inquiry or
investigation, it shall be entitled to examine the books, records and premises
of the Company and the Guarantor, personally or by agent or attorney; and

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

          Section 604.  NOT RESPONSIBLE FOR RECITALS OR ISSUANCE OF SECURITIES.
The recitals contained herein and in the Securities, except the certificates of
authentication, shall be taken as the statements of the Company or the
Guarantor, as applicable, and the Trustee assumes no responsibility for their
correctness. The Trustee makes no representations as to the validity or
sufficiency of this Indenture or of the Securities. The Trustee shall not be
accountable for the use or application by the Company or the Guarantor of
Securities or the proceeds thereof.

          Section 605.  MAY HOLD SECURITIES. The Trustee, any Paying Agent, the
Security Registrar or any other agent of the Company or the Guarantor, in its
individual or any other capacity, may become the owner or pledgee of Securities
and, subject to Sections 608 and 613, may otherwise deal with the Company or the
Guarantor with the same rights it would have if it were not Trustee, Paying

     compensation for all services rendered by it hereunder (which compensation
     shall not be limited by any provision of law in regard to the compensation
     of a trustee of an express trust);

          (2)  except as otherwise expressly provided herein, to reimburse the
     Trustee upon its request for all reasonable expenses, disbursements and
     advances incurred or made by the Trustee in accordance with any provision

the Securities of any series issued hereunder shall be subject to the provisions

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 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 prevent

                                                                              61

referred to in the second to last paragraph of Section 310(b) of the Trust
Indenture Act.

          Section 609.  CORPORATE TRUSTEE REQUIRED; ELIGIBILITY. There shall at

United States of America or of any State, authorized under such laws to exercise
corporate trust powers, having a combined capital and surplus of at least
$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.

          Section 610.  RESIGNATION AND REMOVAL; APPOINTMENT OF SUCCESSOR. (a)

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
resignation, the resigning 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
of the Outstanding Securities of that series, delivered to the Trustee and 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

<Page>

                                                                              62

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
     Securityholder, or

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

          (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 Resolution, or the Guarantor
by a Guarantor's Board Resolution, may remove the Trustee, with respect to the
series, 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

<Page>

                                                                              63

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

<Page>

                                                                              64

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 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

                                                                              65

of the parties hereto. In case any Securities shall have been authenticated, but
not delivered, by the Trustee then in office, any successor by merger,
conversion or consolidation to such authenticating Trustee may adopt such
authentication and deliver the Securities so authenticated with the same effect
as if such successor Trustee had itself authenticated such Securities.

          Section 613.  PREFERENTIAL COLLECTION OF CLAIMS AGAINST COMPANY. (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 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

<Page>

                                                                              66

           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;

               (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.

                                                                              67

          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 securities realize, as a result of payments from such special
account and payments of 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, 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

                                                                              68

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 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:

                (ii) 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

               (iii) 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 securities 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;

<Page>

                                                                              69

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

          (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, acceptances or obligations which fall within the
     classification 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 securities 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
     incurred by the Company for the purpose of financing the purchase,
     processing, manufacturing, shipment, storage or sale of goods, wares or
     merchandise and which is secured by

                                                                              70

     documents 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 the security is received by the Trustee simultaneously with the
     creation 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, 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

                                                                              71

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.

          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.

          Section 701.  COMPANY TO FURNISH TRUSTEE NAMES AND ADDRESSES OF
SECURITYHOLDERS. The Company will furnish or cause to be furnished to the
Trustee

          (a)  semi-annually, not more than 30 days after each Regular Record
Date, in each year in such form as the Trustee may reasonably require, a list of
the names and addresses of the Holders of Securities of such series as of such
date, and

          (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.

          Section 702.  PRESERVATION OF INFORMATION; COMMUNICATIONS TO
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

               (ii) inform such applicants as to the approximate number of
       Holders of Securities of such series or all Securities, 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), and as to the
       approximate cost of mailing to such Securityholders the form of proxy or
       other communication, if any, specified in such application.

          If the Trustee shall elect not to afford such applicants access to
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
Securityholders, 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

                                                                              74

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.

          (c)  Every Holder of Securities, by receiving and holding the same,
agrees with the Company and the Trustee that neither the Company nor the Trustee
shall be held accountable by reason of 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
used in this Section means May 15 of each year. Within 60 days after the
reporting date in each year, beginning in 2004, the Trustee shall transmit by
mail to all Securityholders, as their names and addresses appear in the Security
Register, a brief report dated as of such reporting date with respect to any of
the following events which may have occurred during the 12 months preceding the

date of such report (but if no such event has occurred within such period no
report need be transmitted):

          (1)  any change to its eligibility under Section 609 and its
     qualifications under Section 608;

          (2)  the creation of or any material change to a relationship
     specified in Section 310(b)(1) through Section 310(b)(10) of the Trust
     Indenture Act;

          (3)  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) which remain unpaid on the date of such report,
     and for the reimbursement of which it claims or may claim a lien or 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 1/2 of 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 held as collateral
     security therefor, except an indebtedness based upon a creditor
     relationship arising in a manner described in Section 613(b)(2), (3), (4)
     or (6);

          (5)  any change to the property and funds, if any, physically in the
     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

          (5)  to establish any form of Security, as provided in Article Two,
     and to provide for the issuance of any series of Securities as provided in

     administration of the trusts hereunder by more than one Trustee, pursuant
     to Section 611; or

          (7)  to add any additional Events of Default in respect of the

With the consent of the Holders of not less than a majority in principal amount
of the Outstanding Securities of each series affected by such supplemental
indenture or indentures, by Act of said Holders delivered to the Company, the

the Guarantor, when authorized by a Guarantor's Board Resolution, and the
Trustee may enter into an indenture or indentures supplemental hereto for the
purpose of adding any provisions to or changing in any manner or eliminating any
of the provisions of this Indenture or of modifying in any manner the rights of
the Holders of the Securities of each such series under this Indenture;
PROVIDED, HOWEVER, that no such supplemental indenture

                                                                              81

shall, without the consent of the Holder of each Outstanding Security affected
thereby,

          (1)  change the Maturity of the principal of, or the Stated Maturity
     of any premium on, or any installment of interest on, any Security, or
     reduce the principal amount thereof or the interest or any premium thereon,
     or change the method of computing the amount of principal thereof or
     interest thereon on any date or change any Place of Payment where, or the

     except to increase any such percentage or to provide that certain other
     provisions of this Indenture cannot be modified or waived without the
     consent of the Holder of each Outstanding Security affected thereby.

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

          It shall not be necessary for any Act of 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.

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

thereafter authenticated and delivered hereunder shall be bound thereby to the
extent provided therein.

          Section 905.  CONFORMITY WITH TRUST INDENTURE ACT. Every supplemental
indenture executed pursuant to this Article shall conform to the requirements of

                                   COVENANTS

          Section 1001. PAYMENT OF PRINCIPAL, PREMIUM AND INTEREST. With
respect to each series of Securities, the Company will duly and punctually pay
the principal of (and premium, if any) and interest on such Securities in
accordance with their terms and this Indenture, and will duly comply with all
the other terms, agreements and conditions contained in, or made in the
Indenture for the benefit of, the Securities of such series.

          Section 1002. MAINTENANCE OF OFFICE OR AGENCY. The Company will
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
respect of the Securities and this Indenture may be served. The Company will
give prompt written notice to the Trustee of the location, and of any change in
the location, of such office or agency. If at any time the Company shall fail to
maintain such office or agency or shall fail to furnish the Trustee with the
address thereof, such presentations, surrenders, notices and demands may be made
or served at the principal Corporate Trust Office of the Trustee, and the
Company hereby appoints the Trustee its agent to receive all such presentations,
surrenders, notices and demands.

          The Guarantor will maintain an office or agency in each Place of
Payment where Securities to which the Guarantee applies may be presented or
surrendered for payment pursuant to the Guarantee and where notices and demands
to or upon the Guarantor in respect of the Guarantee and this Indenture may be
served. The Guarantor will give prompt written notice to the Trustee of the
location, and any change in the location, of such office or agency. If at any
time the Guarantor shall fail to maintain any such office or agency or shall
fail to furnish the Trustee with the address thereof, such presentations,
surrenders and demands may be made or served at the Principal Corporate Trust
Office of the Trustee, and the Guarantor hereby appoints the Trustee as its
agent to receive all such presentations, surrenders and demands.

          Section 1003. MONEY FOR SECURITY PAYMENTS TO BE HELD IN TRUST. If the
Company shall at any time act as its

                                                                              84

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 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
(and premium, if any) or interest on, any Securities of such series, deposit
with a Paying Agent a sum sufficient to pay the principal (and premium, if any)
or interest so becoming due, such sum to be held in trust for the benefit of the
Persons entitled to such principal (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

                                                                              85

this Indenture with respect to any series of Securities or for any other
purpose, pay, or by Company Order or 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

                                                                              86

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.

          Section 1006. LIMITATION ON LIENS. So long as any Securities are
Outstanding, neither the Company nor the Guarantor will, nor will it permit any
of its respective Subsidiaries to create, assume, incur or suffer to exist (i)
any Lien upon any stock or indebtedness of any Subsidiary, whether owned on the
date of this Indenture or hereafter acquired, to secure any Debt of the Company,
the Guarantor or any other Person (other than the Securities), and (ii) any Lien
upon any other Property, whether owned or leased on the date of this Indenture,
or thereafter acquired, to secure any Debt of the Company, the Guarantor or any
other person (other than the Securities) without in

<Page>

                                                                              87

any such case making effective provision whereby all of the Securities
Outstanding shall be directly secured equally and ratably with such Debt,
excluding, however, from the operation of the foregoing provisions of this
Section 1006 any Lien existing on the date of this Indenture or any Lien upon
stock or indebtedness or other Property of any Person existing at the time such
Person becomes a Subsidiary, or existing upon stock or indebtedness of a
Subsidiary or any other Property at the time of acquisition of such stock or
indebtedness or other Property, and any extension, renewal or replacement (or
successive extensions, renewals or replacements) in whole or in part of any such
Lien; PROVIDED, however, that the principal amount of Debt secured thereby shall
not exceed the principal amount of Debt so secured at the time of such
extension, renewal or replacement; and PROVIDED further, that such Lien shall be
limited to all or such part of the stock or indebtedness or other Property which
secured the Lien so extended, renewed or replaced.

          Notwithstanding the foregoing, each of the Company and the Guarantor
may, and may permit any Subsidiary to, create, assume, incur or suffer to exist
(i) any Permitted Liens and (ii) any Lien upon any Property without equally and
ratably securing the Securities if the aggregate amount of all Debt then
outstanding secured by such Lien and all similar Liens does not exceed 15% of
the total consolidated stockholders' equity (including preferred stock) of the
Guarantor as shown on the audited consolidated balance sheet contained in the
latest annual report to stockholders of the Guarantor; PROVIDED that Debt
secured by Permitted Liens shall not be included in the amount of such secured
Debt.

          Section 1007. LIMITATION ON SALE AND LEASEBACK TRANSACTIONS. So long
as any Securities are Outstanding neither the Company nor the Guarantor will,
nor will it permit any of its respective Subsidiaries to, enter into any
arrangement with any Person pursuant to which the Company, the Guarantor or any
Subsidiary leases any Property that has been or is to be sold or transferred by
the Company, the Guarantor or the Subsidiary to such Person (a "sale and
leaseback transaction") unless (i) the Company, the Guarantor or such Subsidiary

ratably securing the Securities Outstanding) in an amount equal to the present
value of the lease payments with

                                                                              88

respect to the term of the lease remaining on the date as of which the amount is
being determined under the provisions described in Section 1006; (ii) the lease

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

                                                                              89

          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 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.

                                                                              90

          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, 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.

<Page>

                                                                              91

          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 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 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,

<Page>

                                                                              93

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 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.

                                 ARTICLE TWELVE

                            GUARANTEE OF SECURITIES

          Section 1201. 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 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

<Page>

                                                                              94

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 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.

                                                                              95

          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 1201 by reason of his, her or its status as
such stockholder, officer, director, employee or incorporator.

          The Guarantee set forth in this Section 1201 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 1202. EXECUTION OF NOTATIONS OF GUARANTEE. To evidence its
Guarantee to the Holders specified in Section 1201, 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
1201 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

                                                                              96

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.

          IN WITNESS WHEREOF, the parties hereto have caused this Indenture to
be duly executed, all as of the day and year first above written.

     FIRST SUPPLEMENTAL INDENTURE, dated as of May 19, 2003 (the "SUPPLEMENTAL

     WHEREAS, the Company and the Guarantor executed and delivered the Indenture
to the Trustee to provide for the future issuance of its Securities, to be
issued from time to time in one or more series as might be determined by the
Company under the Indenture, in an unlimited aggregate principal amount which
may be authenticated and delivered thereunder as in the Indenture provided;

     WHEREAS, pursuant to the terms of the Indenture, the Company desires to
provide for the establishment of a new series of its Securities to be known as
its 5.875% Senior Notes due 2013 (the "NOTES"), the form of such Notes and the
terms, provisions and conditions thereof to be as provided in the Indenture and
this First Supplemental Indenture; and

     WHEREAS, the Company and the Guarantor desire and have requested the
Trustee to join with them in the execution and delivery of this First
Supplemental Indenture, and all requirements necessary to make this First
Supplemental Indenture a valid instrument, enforceable in accordance with its
terms, and to make the Notes, when executed by the Company and authenticated and
delivered by the Trustee, and the Guarantees endorsed thereon, when executed by
the Guarantor, the legal, valid and binding obligations of the Company and the
Guarantor, as the case may be, have been performed and fulfilled, and the
execution and delivery of this First Supplemental Indenture and the Notes have
been in all respects duly authorized.

     NOW, THEREFORE, in consideration of the purchase and acceptance of the
Notes by the holders thereof, and for the purpose of setting forth, as provided
in the Indenture, the form of the Notes and the terms, provisions and conditions
thereof, the Company and the Guarantor, as the case may be, covenant and agree
with the Trustee as follows:

                                   ARTICLE 1

Securities designated the "5.875% Senior Notes due 2013".

     Section 1.02. The Notes shall be initially limited in aggregate principal
amount to $700,000,000. Without the consent of the Holders of the Notes, the
aggregate principal amount of the Notes may be increased in the future, on the
same terms and conditions and with the same CUSIP number as the Notes have, so
that such additional notes and the

                                        1
<Page>

outstanding Notes shall form a single series of Securities under the Indenture

York provided for that purpose and transfers of the Notes will also be
registrable at any of the Company's other offices or agencies as the Company may
maintain for that purpose; provided, however, that payment of interest may be
made at the option of the Company by check mailed to the registered holder at
such address as shall appear in the Security Register and that the payment of

Notes to the Trustee.

annum from May 19, 2003 until the principal thereof becomes due and payable,
payable semi-annually in arrears on May 15 and November 15 of each year (each,
an "INTEREST PAYMENT DATE", commencing on November 15, 2003), to the person in
whose name such Note (or one or more Predecessor Securities) is registered at
the close of business on the Regular Record Date for such interest installment,
which, except as set forth below, shall be the May 1 or November 1, as the case
may be, preceding the Interest Payment Date with respect to such interest
installment.

     (b)  Any installment of interest not punctually paid or duly provided for

Regular Record Date and may be paid to the person in whose name such Note (or
one or more Predecessor Securities) is registered at the close of business on a
Special Record Date to be fixed by the Trustee for the payment of such defaulted
interest, notice whereof to be given to the registered holders of the Notes not
less than 10 days prior to such Special Record Date, or may be paid at any time
in any other lawful manner not inconsistent with the requirements of any
securities exchange on which the Notes may be listed, and upon such notice as
may be required by such exchange, all as more fully provided in the Indenture.

     (c)  The amount of interest payable for any period will be computed on the
basis of a 360-day year consisting of twelve 30-day months. In the event that
any date on which interest is payable on the Notes is not a Business Day, then
payment of interest payable on such date will be made on the next succeeding day
which is a Business Day (and without any interest or other payment in respect of
any such delay).

     Section 1.05. The Notes are not entitled to any sinking fund.

                               REVERSE OF SECURITY

1. INTEREST
          Fund American Companies, Inc., a Delaware corporation (such
corporation, and its successors and assigns under the Indenture hereinafter
referred to, being herein called the "Company"), promises to pay interest on the
principal amount of this Security at the rate per annum shown above. The Company
will pay interest semiannually in arrears on May 15 and November 15 of each
year, commencing November 15, 2003. Interest on the Securities will accrue from
the most recent date to which interest has been paid or, if no interest has been
paid, from May 19, 2003. Interest will be computed on the basis of a 360-day
year comprised of twelve 30-day months.

          The Company shall pay interest on overdue principal and premium, if
any, and interest on overdue installments of interest, to the extent lawful, at
the same rate per annum payable on the principal of this Security.

2. METHOD OF PAYMENT
          The Company will pay interest on the Securities (except overdue
interest) to the Persons who are registered Holders of Securities at the close
of business on May 1 or November 1 next preceding the Interest Payment Date even
if Securities are canceled after the Regular Record Date and on or before the
Interest Payment Date. Holders must surrender Securities to a Paying Agent to
collect principal payments. The Company will pay principal and interest in money
of the United States that at the time of payment is legal tender for payment of
public and private debts. Payments in respect of the Securities represented by a
Global Security (including principal, premium, if any, and interest) will be
made by wire transfer of immediately available funds to the accounts specified
by The Depository Trust Company. The Company will make all payments in respect
of a certificated Security (including principal, premium, if any, and interest)
by mailing a check to the registered address of each Holder thereof; provided,
however, that payments on a certificated Security will be made by wire transfer
to a U.S. dollar account maintained by the payee with a bank in the United
States if such Holder elects payment by wire transfer by giving written notice
to the Trustee or the Paying Agent to such effect designating such account no
later than 30 days immediately preceding the relevant due date for payment (or
such other date as the Trustee may accept in its discretion).

3. PAYING AGENT AND REGISTRAR
          Initially, Bank One, National Association (the "Trustee"), will act as
Paying Agent and Registrar. The Company may appoint and change any Paying Agent,
Registrar or co-Registrar without notice. The Company or any of its domestically
incorporated Wholly Owned Subsidiaries may act as Paying Agent, Registrar or
co-Registrar.

4. INDENTURE
          The Company issued the Securities under an Indenture dated as of May
19, 2003, as supplemented by the First Supplemental Indenture dated as of May
19, 2003

                                       A-7
<Page>

(together, the "Indenture"), among the Company, the Guarantor and the Trustee.
The terms of the Securities include those stated in the Indenture and those made
part of the Indenture by reference to the Trust Indenture Act of 1939 (15 U.S.C.
Sections 77aaa-77bbbb) as in effect on the date of the Indenture (the "TIA").
Terms defined in the Indenture and not defined herein have the meanings ascribed
thereto in the Indenture. The Securities are subject to all such terms, and
Securityholders are referred to the Indenture and the TIA for a statement of
those terms. To the extent permitted by applicable law, in the event of any
inconsistency between the terms of this Security and the terms of the Indenture,
the terms of the Indenture shall control.

          The Securities are general unsecured obligations of the Company. The
Indenture contains covenants that limit the ability of the Company and its
Subsidiaries to grant Liens; enter into Sale/Leaseback Transactions; and
consolidate, merge or transfer all or substantially all of its assets and the
assets of its Subsidiaries. These covenants are subject to important exceptions
and qualifications set forth in the Indenture.

5. OPTIONAL REDEMPTION
          The Securities are redeemable as a whole at any time or in part from
time to time, at the option of the Company, at a redemption price equal to the
greater of (i) 100% of the principal amount of such Securities or (ii) the sum
of the present values of the remaining scheduled payments of principal and
interest (other than accrued interest) on the Securities being redeemed,
discounted to the redemption date on a semi-annual basis (assuming a 360-day
year consisting of twelve 30-day months) at the Treasury Rate plus 50 basis
points plus, in either case, any interest accrued but not paid to the date of
redemption.

6. 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. Unless the Company defaults in payment of the redemption
price, on and after the redemption date interest will cease to accrue on the
Securities or portions thereof called for redemption.

7. GUARANTEE
          The payment by the Company of the principal of, and premium and
interest on, the Securities is irrevocably and unconditionally guaranteed on a
senior basis by the Guarantor.

8. DENOMINATIONS; TRANSFER; EXCHANGE
          The Securities are in registered form in denominations of $1,000
principal amount and integral multiples of $1,000. A Holder may transfer or
exchange Securities in accordance with the Indenture. The Company may require a
Holder, among other things, to furnish appropriate endorsements or transfer
documents and to pay any taxes or other governmental charge that may be imposed
in connection with any transfer or exchange of Securities or permitted by the
Indenture. The Company need not issue, transfer or exchange any Security of any
series during a period beginning at the opening

                                       A-8
<Page>

of business 15 days before the day of the mailing of a notice of redemption of
Securities of such series selected for redemption and ending at the close of
business on the date of such mailing, or transfer or exchange any Security
selected for redemption in whole or in part, except for the portion of such
Security not selected for redemption.

9. PERSONS DEEMED OWNERS
          The person in whose name any Security is registered in the Security
Register may be treated as the owner of it for all purposes.

payment as general creditors and all liability of the Trustee or such paying
agent with respect to such money shall thereupon cease.

11. DISCHARGE AND DEFEASANCE
          Subject to certain conditions, the Company at any time shall be

or supplement any inconsistency or make any other provisions with respect to

adversely affect the interest of any Holder.

13. DEFAULTS AND REMEDIES
          The events of default and remedies specified in the Indenture apply to
the Securities. If an Event of Default, as defined in the Indenture, occurs and

Outstanding Securities may direct the Trustee in its exercise of any trust or
power.

                               REVERSE OF SECURITY

1. INTEREST
          Fund American Companies, Inc., a Delaware corporation (such
corporation, and its successors and assigns under the Indenture hereinafter
referred to, being herein called the "Company"), promises to pay interest on the
principal amount of this Security at the rate per annum shown above. The Company
will pay interest semiannually in arrears on May 15 and November 15 of each
year, commencing November 15, 2003. Interest on the Securities will accrue from
the most recent date to which interest has been paid or, if no interest has been
paid, from May 19, 2003. Interest will be computed on the basis of a 360-day
year comprised of twelve 30-day months.

          The Company shall pay interest on overdue principal and premium, if
any, and interest on overdue installments of interest, to the extent lawful, at
the same rate per annum payable on the principal of this Security.

2. METHOD OF PAYMENT
          The Company will pay interest on the Securities (except overdue
interest) to the Persons who are registered Holders of Securities at the close
of business on May 1 or November 1 next preceding the Interest Payment Date even
if Securities are canceled after the Regular Record Date and on or before the
Interest Payment Date. Holders must surrender Securities to a Paying Agent to
collect principal payments. The Company will pay principal and interest in money
of the United States that at the time of payment is legal tender for payment of
public and private debts. Payments in respect of the Securities represented by a
Global Security (including principal, premium, if any, and interest) will be
made by wire transfer of immediately available funds to the accounts specified
by The Depository Trust Company. The Company will make all payments in respect
of a certificated Security (including principal, premium, if any, and interest)
by mailing a check to the registered address of each Holder thereof; provided,
however, that payments on a certificated Security will be made by wire transfer
to a U.S. dollar account maintained by the payee with a bank in the United
States if such Holder elects payment by wire transfer by giving written notice
to the Trustee or the Paying Agent to such effect designating such account no
later than 30 days immediately preceding the relevant due date for payment (or
such other date as the Trustee may accept in its discretion).

3. PAYING AGENT AND REGISTRAR
          Initially, Bank One, National Association (the "Trustee"), will act as
Paying Agent and Registrar. The Company may appoint and change any Paying Agent,
Registrar or co-Registrar without notice. The Company or any of its domestically
incorporated Wholly Owned Subsidiaries may act as Paying Agent, Registrar or
co-Registrar.

4. INDENTURE
          The Company issued the Securities under an Indenture dated as of May
19, 2003, as supplemented by the First Supplemental Indenture dated as of May
19, 2003

                                       B-7
<Page>

(together, the "Indenture"), among the Company, the Guarantor and the Trustee.
The terms of the Securities include those stated in the Indenture and those made
part of the Indenture by reference to the Trust Indenture Act of 1939 (15 U.S.C.
Sections 77aaa-77bbbb) as in effect on the date of the Indenture (the "TIA").
Terms defined in the Indenture and not defined herein have the meanings ascribed
thereto in the Indenture. The Securities are subject to all such terms, and
Securityholders are referred to the Indenture and the TIA for a statement of
those terms. To the extent permitted by applicable law, in the event of any
inconsistency between the terms of this Security and the terms of the Indenture,
the terms of the Indenture shall control.

          The Securities are general unsecured obligations of the Company. The
Indenture contains covenants that limit the ability of the Company and its
Subsidiaries to grant Liens; enter into Sale/Leaseback Transactions; and
consolidate, merge or transfer all or substantially all of its assets and the
assets of its Subsidiaries. These covenants are subject to important exceptions
and qualifications set forth in the Indenture.

5. OPTIONAL REDEMPTION
          The Securities are redeemable as a whole at any time or in part from
time to time, at the option of the Company, at a redemption price equal to the
greater of (i) 100% of the principal amount of such Securities or (ii) the sum
of the present values of the remaining scheduled payments of principal and
interest (other than accrued interest) on the Securities being redeemed,
discounted to the redemption date on a semi-annual basis (assuming a 360-day
year consisting of twelve 30-day months) at the Treasury Rate plus 50 basis
points plus, in either case, any interest accrued but not paid to the date of
redemption.

6. 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. Unless the Company defaults in payment of the redemption
price, on and after the redemption date interest will cease to accrue on the
Securities or portions thereof called for redemption.

7. GUARANTEE
          The payment by the Company of the principal of, and premium and
interest on, the Securities is irrevocably and unconditionally guaranteed on a
senior basis by the Guarantor.

8. DENOMINATIONS; TRANSFER; EXCHANGE
          The Securities are in registered form in denominations of $1,000
principal amount and integral multiples of $1,000. A Holder may transfer or
exchange Securities in accordance with the Indenture. The Company may require a
Holder, among other things, to furnish appropriate endorsements or transfer
documents and to pay any taxes or other governmental charge that may be imposed
in connection with any transfer or exchange of Securities or permitted by the
Indenture. The Company need not issue, transfer or exchange any Security of any
series during a period beginning at the opening

                                       B-8
<Page>

of business 15 days before the day of the mailing of a notice of redemption of
Securities of such series selected for redemption and ending at the close of
business on the date of such mailing, or transfer or exchange any Security
selected for redemption in whole or in part, except for the portion of such
Security not selected for redemption.

9. PERSONS DEEMED OWNERS
          The person in whose name any Security is registered in the Security
Register may be treated as the owner of it for all purposes.

10. UNCLAIMED MONEY
          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.

11. DISCHARGE AND DEFEASANCE
          Subject to certain conditions, the Company at any time shall be
entitled to terminate some or all of its obligations under the Securities and
the Indenture if the Company or the Guarantor irrevocably deposits with the
Trustee money or U.S. Government Obligations for the payment of principal and
interest on the Securities to maturity or redemption, as the case may be.

12. AMENDMENT, WAIVER
          Subject to certain exceptions, the Indenture or the Securities may be
amended or supplemented with the consent of the Holders of not less than a
majority in principal amount of the Outstanding Securities, and any past default
or compliance with any covenant or condition may be waived with the consent of
the Holders of at least a majority in principal amount of the Securities then
Outstanding. Without notice to or the consent of any Holder, the parties thereto
may supplement the Indenture to, among other things, cure any ambiguity, correct
or supplement any inconsistency or make any other provisions with respect to
matters or questions arising thereunder, provided that such change does not
adversely affect the interest of any Holder.

13. DEFAULTS AND REMEDIES
          The events of default and remedies specified in the Indenture apply to
the Securities. If an Event of Default, as defined in the Indenture, occurs and
is continuing, the Trustee or the Holders of not less than 25% in aggregate
principal amount of the Securities then Outstanding may declare all the
Securities to be due and payable. Holders may not enforce the Indenture or the
Securities except as provided in the Indenture. The Trustee may require
indemnity satisfactory to it before it enforces the Indenture or the Securities.
Subject to certain limitations, Holders of a majority in principal amount of the
Outstanding Securities may direct the Trustee in its exercise of any trust or
power.

14. TRUSTEE DEALINGS WITH THE COMPANY
          Subject to certain limitations imposed by the TIA, the Trustee under
the Indenture, in its individual or any other capacity, may become the owner or
pledgee of Securities and may otherwise deal with and collect obligations owed
to it by the Company or its Affiliates and may otherwise deal with the Company
or its Affiliates with the same rights it would have if it were not the Trustee.

15. BENEFITS OF INDENTURE
          Nothing in the Indenture or in the Securities, express or implied,
shall give to any Person, other than the Company, the Guarantor, the Trustee and
their successors thereunder, 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 the Indenture.

Trustee (or an authenticating agent) manually signs the certificate of
