where notice to Holders is given by mail, neither the failure to mail such

shall affect the sufficiency of such notice with respect to other Holders.
Any notice mailed to a Holder in the manner herein prescribed shall be
conclusively deemed to have been received by such Holder, whether or not such
Holder actually receives such notice.

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

required or permitted under this Indenture shall be in the English language,

of the Indenture shall alter or impair the obligation of the Company, which is
absolute and unconditional, to pay the principal of (and premium, if any) and
interest on this Security at the times, place and rate, and in the coin or

need not be accompanied by an Opinion of Counsel) with regard to the reduction
in the principal amount of Securities represented thereby, together with the
written statement contemplated by the last sentence of Section 3.03.

legend in substantially the following form or such similar form as may be
required by the Depositary:

          (23) if the Securities of such series are to be issuable in definitive
     form (whether upon original issue or upon exchange of a temporary Security

          (26) any other terms of the series (which terms shall not be
     inconsistent with the provisions of this Indenture, except as permitted by

     All Securities of any one series (other than Securities offered in a
Periodic Offering) shall be substantially identical except as to denomination
and except as may otherwise be provided by or pursuant to the Board Votes
referred to above and, subject to Section 3.03, set forth, or determined in
the manner provided, in the Officers' Certificate referred to above or in any
such indenture supplemental hereto. All Securities of any one series need not
be issued at the same time and, unless otherwise provided, a series may be
reopened, without the consent of the Holders, for issuances of additional
Securities of such series.

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

     With respect to Securities of a series offered in a Periodic Offering, such
Board Vote and Officers Certificate or supplemental indenture may provide
general terms or parameters for Securities of such series and provide either
that the specific terms of particular Securities of such series shall be
specified in a Company Order or that such terms shall be determined by the
Company or its agents in accordance with other procedures specified in a Company
Order as contemplated by the third paragraph of Section 3.03.

     SECTION 3.02. DENOMINATIONS.

     The Securities of each series shall be issued in registered form without
coupons in such denominations as shall be specified as contemplated by
Section 3.01. In the absence of any such provisions with respect to the
Securities of any series, the Securities of such series, other than Global
Securities (which may be of any denomination), shall be issuable in
denominations of $1,000 or any amount in excess thereof which is an integral
multiple of $1,000.

     SECTION 3.03. EXECUTION, AUTHENTICATION, DELIVERY AND DATING.

     The Securities shall be executed on behalf of the Company by its Chairman
of the Board, its President or one of its Vice Presidents, under its corporate
seal affixed thereto or reproduced thereon attested by its Secretary or one of
its Assistant Secretaries. The signature of any of these officers on the
Securities may be manual or facsimile signatures of the present or any future
such authorized officer and may be imprinted or otherwise reproduced on the
Securities.

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

     At any time and from time to time after the execution and delivery of this
Indenture, the Company may deliver Securities of any series executed by the
Company to the Trustee for authentication, together with a Company Order for the
authentication and delivery of such Securities, or, in the case of Securities
offered in a Periodic Offering, from time to time in accordance with such other
procedures (including, without limitation, the receipt by the Trustee of
electronic instructions from the Company or its duly authorized agents, promptly
confirmed in writing by the Company) acceptable to the Trustee as may be
specified from time to time by a Company Order for establishing the specific
terms of particular Securities being so offered, and the Trustee in accordance
with the Company Order shall authenticate and deliver such Securities. If the
form or terms of the Securities of the series have been established by or
pursuant to one or more Board Votes as permitted by Sections 2.01 and 3.01, in
authenticating such Securities and accepting the additional responsibilities
under this Indenture in relation to such Securities, the Trustee shall be
entitled to receive, and (subject to Section 6.01) shall be fully protected in
relying upon, an Opinion of Counsel stating:

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

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

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

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

          (e) that the Company has the corporate power to issue such Securities,
and has duly taken all necessary corporate action with respect to such issuance;
and

          (f) that the issuance of such Securities will not contravene the
certificate of organization or by-laws of the Company or result in any violation
of any of the terms or provisions of any law or regulation or of any indenture,
mortgage or other agreement known to such Counsel by which the Company is bound.

                                       24
<Page>

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

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

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

     With respect to Securities of a series offered in a Periodic Offering, the
Trustee may rely, as to the authorization by the Company of any of such
Securities, the form and terms thereof and the legality, validity, binding
effect and enforceability thereof, upon the Opinion of Counsel and other
documents delivered pursuant to Sections 2.01 and 3.01 and this Section 3.05, as
applicable, in connection with the first authentication of Securities of such
series and it shall not be necessary for the Company to deliver such Opinion of
Counsel and other documents (except as may be required by the specified other
procedures, if any, referred to above) at or prior to the time of authentication
of each Security of such series unless and until the Trustee receives notice
that such Opinion of Counsel or other documents have been superseded or revoked,
and may assume compliance with any conditions specified in such Opinion of
Counsel (other than any conditions to be performed by the Trustee). If such form
or terms have been so established, the Trustee shall not be required to
authenticate such Securities if the issue of such Securities pursuant to this
Indenture will affect the Trustee's own rights, duties or immunities under the
Securities and this Indenture or otherwise in a manner which is not reasonably
acceptable to the Trustee.

     Each Security shall be dated the date of its authentication.

     No Security shall be entitled to any benefit under this Indenture or be
valid or obligatory for any purpose unless there appears on such Security a
certificate of authentication substantially in the form provided for herein
executed by the Trustee by manual signature, and such certificate upon any
Security shall be conclusive evidence, and the only evidence, that such Security
has been duly authenticated and delivered hereunder and is entitled to the
benefits of this Indenture. Notwithstanding the foregoing, if any Security
(including a Global Security) shall have been authenticated and delivered
hereunder but never issued and sold by the Company, and the Company shall
deliver such Security to the Trustee for cancellation as provided in Section
3.09 together with a written statement (which need not comply with Section 1.02
and need not be accompanied by an Opinion of Counsel) stating that such Security
has never been issued and sold by the Company, for all purposes of this
Indenture such Security shall be deemed never to have been authenticated and
delivered hereunder and shall never be entitled to the benefits of this
Indenture.

     SECTION 3.04. TEMPORARY SECURITIES.

          (a) Pending the preparation of definitive Securities of any series,
the Company may execute, and upon Company Order the Trustee shall
authenticate and deliver, temporary Securities which are printed,
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, in registered form and with such
appropriate insertions, omissions, substitutions and other variations as the
officers executing such Securities may determine, as evidenced by their
execution of such Securities. In the case of Securities of any series, such
temporary Securities may be in global form.

     Except in the case of temporary Global Securities (which shall be exchanged
as otherwise provided herein or as otherwise provided in or pursuant to a Board
Vote or supplemental indenture pursuant to Section 3.01), if temporary
Securities of any series are issued, the Company will cause definitive
Securities of that series to be prepared without unreasonable delay. After the
preparation of definitive Securities of such series, the temporary Securities of
such series shall be exchangeable for definitive Securities of like tenor of
such series upon surrender of the temporary Securities of such series at the
office or agency of the Company in any Place of Payment for that series, without
charge to the Holder. Upon surrender for cancellation of any one or more
temporary Securities of any series the Company shall execute and the Trustee
shall authenticate and deliver in exchange therefor a like principal amount of
definitive Securities of the same series and of like tenor and of any authorized
denominations. Until so exchanged, the temporary Securities of any series shall
in all respects be entitled to the same benefits under this Indenture as
definitive Securities of such series and tenor.

          (b) Unless otherwise provided in or pursuant to a Board Vote or
supplemental indenture pursuant to Section 3.01, the following provisions of
this Section 3.04(b) shall govern the exchange of temporary Securities other
than through the facilities of the DTC. If any such temporary Security is issued
in global form, then such temporary Global Security shall, unless otherwise
provided therein, be delivered to the London office of a depositary or common
depositary upon and pursuant to written direction of the Company (the "Common
Depositary"), for the benefit of Euroclear and Clearstream, for credit to the
respective accounts of the beneficial owners of such Securities (or to such
other accounts as they may direct).

     Without unnecessary delay but in any event not later than the date
specified in, or determined pursuant to the terms of, any such temporary
Global Security (the "Exchange Date"), the Company shall deliver to the
Trustee definitive Securities, in aggregate principal amount equal to the
principal amount of such temporary Global Security, executed by the Company.
On or after the Exchange Date, such temporary Global Security shall be
surrendered by the Common Depositary to the Trustee, as the Company's agent
for such purpose, to be exchanged, in whole or from time to time in part, for
definitive Securities without charge, and the Trustee shall authenticate and
deliver, in exchange for each portion of such temporary Global Security, an
equal aggregate principal amount of definitive Securities of the same series
of authorized denominations and of like tenor as the portion of such
temporary Global Security to be exchanged. The definitive Securities to be
delivered in exchange for any such temporary Global Security shall be in
registered form, permanent global registered form, or any combination
thereof, as specified as contemplated by Section 3.01, and, if any
combination thereof is so specified, as requested by the beneficial owner
thereof (as directed by or pursuant to information provided by the Common
Depositary); PROVIDED, HOWEVER, that, unless otherwise specified in such
temporary Global Security, upon such presentation by the Common Depositary,
such temporary Global Security shall be accompanied by a certificate dated
the Exchange Date or a subsequent date and signed by Euroclear as to the
portion of such temporary Global Security held for its account then to be
exchanged and a certificate dated the Exchange Date or a subsequent date and
signed by

                                       26
<Page>

Clearstream as to the portion of such temporary Global Security held for its
account then to be exchanged, in such form as may be established pursuant to
Section 3.01.

     Unless otherwise specified in such temporary Global Security, the interest
of a beneficial owner of Securities of a series in a temporary Global Security
shall be exchanged for definitive Securities of the same series and of like
tenor following the Exchange Date when the account holder instructs Euroclear or
Clearstream, as the case may be, to request such exchange on his behalf and
delivers to Euroclear or Clearstream, as the case may be, a certificate in the
form as may be established pursuant to Section 3.01, dated no earlier than 15
days prior to the Exchange Date, copies of which certificate shall be available
from the offices of Euroclear and Clearstream, the Trustee, any Authenticating
Agent appointed for such series of Securities and each Paying Agent. Unless
otherwise specified in such temporary Global Security, any such exchange shall
be made free of charge to the beneficial owners of such temporary Global
Security, except that a Person receiving definitive Securities must bear the
cost of insurance, postage, transportation and the like unless such Person takes
delivery of such definitive Securities in person at the offices of Euroclear or
Clearstream.

     Until exchanged in full as hereinabove provided, the temporary Securities
of any series shall in all respects be entitled to the same benefits under this
Indenture as definitive Securities of the same series and of like tenor
authenticated and delivered hereunder, except that, unless otherwise specified
as contemplated by Section 301, interest payable on a temporary Global Security
on an Interest Payment Date for Securities of such series occurring prior to the
applicable Exchange Date shall be payable to Euroclear and Clearstream on such
Interest Payment Date upon delivery by Euroclear and Clearstream to the Trustee
of a certificate or certificates in such forms as may be established pursuant to
Section 3.01, for credit without further interest on or after such Interest
Payment Date to the respective accounts of Persons who are the beneficial owners
of such temporary Global Security on such Interest Payment Date and who have
each delivered to Euroclear or Clearstream, as the case may be, a certificate
dated no earlier than 15 days prior to the Interest Payment Date occurring prior
to such Exchange Date in the form as may be established pursuant to
Section 3.01. Notwithstanding anything to the contrary herein contained, the
certifications made pursuant to this paragraph shall satisfy the certification
requirements of the preceding two paragraphs of this Section 3.04(b) and of the
third paragraph of Section 3.03 of this Indenture and the interests of the
Persons who are the beneficial owners of the temporary Global Security with
respect to which such certification was made will be exchanged for definitive
Securities of the same series and of like tenor on the Exchange Date or the date
of certification if such date occurs after the Exchange Date, without further
act or deed by such beneficial owners. Except as otherwise provided in this
paragraph, no payments of principal or interest owing with respect to a
beneficial interest in a temporary Global Security will be made unless and until
such interest in such temporary Global Security shall have been exchanged for an
interest in a definitive Security. Any interest so received by Euroclear and
Clearstream and not paid as herein provided shall be returned to the Trustee
prior to the expiration of two years after such Interest Payment Date in order
to be repaid to the Company.

     SECTION 3.05. REGISTRATION, REGISTRATION OF TRANSFER AND EXCHANGE.

     The Company shall cause to be kept at the Corporate Trust Office of the
Trustee or in any office or agency of the Company in a Place of Payment a
register for each series of Securities (the "Security Register") in which,
subject to such reasonable regulations as it may prescribe, the Company shall
provide for the registration of Securities and of transfers of Securities. The
Trustee is hereby appointed

                                       27
<Page>

"Security Registrar" for the purpose of registering Securities and transfers of
Securities as herein provided. In the event that the Trustee shall cease to be
Security Registrar, it shall have the right to examine, and be provided a copy
of, the Security Register at all reasonable times.

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

     At the option of the Holder, Securities of any series may be exchanged for
other Securities of the same series, of any authorized denominations and of a
like aggregate principal amount, bearing a number not contemporaneously
outstanding, and containing identical terms and provisions, upon surrender of
the Securities to be exchanged at the office or agency of the Company in any
Place of Payment for such series. Whenever any Securities are so surrendered for
exchange, the Company shall execute, and the Trustee shall authenticate and
deliver, the Securities which the Holder making the exchange is entitled to
receive.

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

                                       28
<Page>

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

     No service charge shall be made for any registration of transfer or
exchange of Securities, but the Company may require payment of a sum sufficient
to cover any tax or other governmental charge that may be imposed in connection
with any registration of transfer or exchange of Securities, other than
exchanges pursuant to Section 3.04, 9.06 or 11.07 not involving any transfer

     The Company may but shall not be required (i) to issue, register the
transfer of or exchange Securities of any series during a period beginning at
the opening of business 15 days before the day of the mailing of a notice of
redemption of Securities of that series selected for redemption under
Section 11.03 and ending at the close of business on the day of such mailing, or
(ii) to register the transfer of or exchange any Security so selected for
redemption in whole or in part, except the unredeemed portion of any Security
being redeemed in part.

     Notwithstanding the foregoing, except as otherwise specified as
contemplated by Section 3.01, any Global Security shall be exchangeable pursuant
to this Section 3.05 for Securities registered in the name of Persons other than
the Depositary for such Security or its nominee only if (i) such Depositary
notifies the Company that it is unwilling or unable to continue as Depositary
for such Global Security or if at any time such Depositary ceases to be a
clearing agency registered under the Exchange Act, (ii) the Company executes and
delivers to the Trustee a Company Order that such Global Security shall be so
exchangeable or (iii) there shall have occurred and be continuing an Event of
Default with respect to the Securities of such series. Upon the occurrence in
respect of any Global Security of any series of any one or more of the
conditions specified in clauses (i), (ii) or (iii) of the preceding sentence or
such other conditions as may be specified as contemplated by Section 3.01 for
such series, such Global Security may be exchanged for Securities not bearing
the legend specified in Section 2.05 and registered in the name of such Person
as may be specified by the Depositary (including Persons other than the
Depositary).

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

     SECTION 3.06. MUTILATED, DESTROYED, LOST AND STOLEN SECURITIES.

     If any mutilated Security is surrendered to the Trustee, or the Company,
together with, in proper cases, such security or indemnity as may be required by
the Company or the Trustee to save each of them or any agent of either of them
harmless, the Company shall execute and the Trustee shall authenticate and
deliver in exchange therefor a new Security of the same series and of like tenor
and principal amount.

     If there shall be delivered to the Company and the Trustee (i) evidence to
their satisfaction of the destruction, loss or theft of any Security and (ii)
such security or indemnity as may be required by them to save each of them and
any agent of either of them harmless, then, in the absence of notice to the
Company or the Trustee that such Security has been acquired by a bona fide
purchaser, the Company shall execute and upon its written request, the Trustee
shall authenticate and deliver, in lieu of any such destroyed, lost or stolen
Security, a new Security of the same series and of like tenor and principal
amount and bearing a number not contemporaneously outstanding.

     In case any such mutilated, destroyed, lost or stolen Security has become
or is about to become due and payable, the Company in its discretion may,
instead of issuing a new Security, pay such Security.

                                       29
<Page>


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

     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 3.07. PAYMENT OF INTEREST; INTEREST RIGHTS PRESERVED.

     Unless otherwise provided as contemplated by Section 3.01 with respect
to any series of Securities, interest on any Security which is payable, and
is punctually paid or duly provided for, on any Interest Payment Date shall
be paid to the Person in whose name that Security (or one or more Predecessor
Securities) is registered in the Security Register at the close of business
on the Regular Record Date for such Interest Payment Date; ; PROVIDED,
HOWEVER, that each installment of interest on any Security may at the
Company's option be paid by (i) mailing a check for such interest, payable to
or upon the written order of the Person entitled thereto pursuant to Section
308, to the address of such Person as it appears on the Security Register or
(ii) transfer to an account maintained by the payee located inside the United
States.

     Unless otherwise provided as contemplated by Section 3.01, every permanent
global Security will provide that interest, if any, payable on any Interest
Payment Date will be paid to DTC, Euroclear and/or Clearstream, as the case may
be, with respect to that portion of such permanent global Security held for its
account by Cede & Co. or the Common Depositary, as the case may be, for the
purpose of permitting such party to credit the interest received by it in
respect of such permanent global Security to the accounts of the beneficial
owners thereof.

                                       30
<Page>

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

          (1) The Company may elect to make payment of any Defaulted Interest to
     the Persons in whose names the Securities of such series (or their
     respective Predecessor Securities) are registered at the close of business
     on a Special Record Date for the payment of such Defaulted Interest, which
     shall be fixed in the following manner. The Company shall notify the
     Trustee in writing of the amount of Defaulted Interest proposed to be paid
     on each Security of such series and the date of the proposed payment, and
     at the same time the Company shall deposit with the Trustee an amount of
     money equal to the aggregate amount proposed to be paid in respect of such
     Defaulted Interest or shall make arrangements satisfactory to the Trustee
     for such deposit prior to the date of the proposed payment, such money when
     deposited to be held in trust for the benefit of the Persons entitled to
     such Defaulted Interest as in this clause provided. Thereupon the Trustee
     shall fix a Special Record Date for the payment of such Defaulted Interest
     which shall be not more than 15 days and not less than 10 days prior to the
     date of the proposed payment and not less than 10 days after the receipt by
     the Trustee of the notice of the proposed payment. The Trustee shall
     promptly notify the Company of such Special Record Date and, in the name
     and at the expense of the Company, shall cause notice of the proposed
     payment of such Defaulted Interest and the Special Record Date therefor to
     be mailed, first-class postage prepaid, to each Holder of Securities of
     such series at his or her 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 so mailed, such Defaulted Interest shall be paid to
     the Persons in whose names the Securities of such series (or their
     respective Predecessor Securities) are registered at the close of business
     on such Special Record Date and shall no longer be payable pursuant to the
     following clause (2).

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

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

     SECTION 3.08. PERSONS DEEMED OWNERS.

Prior to due presentment of a Security for registration of transfer, the
Company, the Trustee and any agent of the Company or the Trustee may treat the
Person in whose name such Security is registered in the

                                       31
<Page>

Security Register as the owner of such Security for the purpose of receiving
payment of principal of (and premium or Make-Whole Amount, if any) and (subject
to Section 3.07) interest on such Security and for all other purposes
whatsoever, whether or not such Security be overdue, and neither the Company,
the Trustee nor any agent of the Company or the Trustee shall be affected by
notice to the contrary. All such payments so made to any such Person, or upon
such Person's order, shall be valid, and, to the extent of the sum or sums so
paid, effectual to satisfy and discharge the liability for money payable upon
any such Security.

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

     SECTION 3.09. CANCELLATION.

     All Securities surrendered for payment, redemption, repayment, registration
of transfer, conversion, or exchange or for credit against any sinking fund
payment shall, if surrendered to any Person other than the Trustee, be delivered
to the Trustee and shall be promptly cancelled by it. The Company may at any
time deliver to the Trustee for cancellation any Securities previously
authenticated and delivered hereunder which the Company may have acquired in any
manner whatsoever, and may deliver to the Trustee (or to any other Person for
delivery to the Trustee) for cancellation any Securities previously
authenticated hereunder which the Company has not issued and sold, and all
Securities so delivered shall be promptly cancelled by the Trustee. If the
Company shall so acquire any of the Securities, however, such acquisition shall
not operate as a redemption or satisfaction of the indebtedness represented by
such Securities unless and until the same are surrendered to the Trustee for
cancellation. No Securities shall be authenticated in lieu of or in exchange for
any Securities cancelled as provided in this Section, except as expressly
permitted by this Indenture. All cancelled Securities held by the Trustee shall
be destroyed unless otherwise directed by a Company Order.

     SECTION 3.10. COMPUTATION OF INTEREST.

     Except as otherwise specified as contemplated by Section 3.01 for
Securities of any series, interest on the Securities of each series shall be
computed on the basis of a 360-day year of twelve 30-day months.

     SECTION 3.11. PAYMENT TO BE IN PROPER CURRENCY.

     In the case of any Securities denominated in any currency (the "Required
Currency") other than United States Dollars, except as otherwise provided
therein, the obligation of the Company to make any

                                       32
<Page>

payment of principal, premium or interest thereon shall not be discharged or
satisfied by any tender by the Company, or recovery by the Trustee, in any
currency other than the Required Currency, except to the extent that such
tender or recovery shall result in the Trustee timely holding the full amount
of the Required Currency then due and payable. If any such tender or recovery
is in a currency other than the Required Currency, the Trustee may take such
actions as it considers appropriate to exchange such currency for the
Required Currency. The costs and risks of any such exchange, including
without limitation the risks of delay and exchange rate fluctuation, shall be
borne by the Company, the Company shall remain fully liable for any shortfall
or delinquency in the full amount of Required Currency then due and payable,
and in no circumstances shall the Trustee be liable therefor except in the
case of its gross negligence or willful misconduct. The Company hereby waives
any defense of payment based upon any such tender or recovery which is not in
the Required Currency, or which, when exchanged for the Required Currency by
the Trustee, is less than the full amount of Required Currency then due and
payable.

     SECTION 3.12. CUSIP NUMBERS.

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

                    ARTICLE FOUR - SATISFACTION AND DISCHARGE

     SECTION 4.01. SATISFACTION AND DISCHARGE OF INDENTURE.

     This Indenture shall upon Company Request cease to be of further effect
with respect to any series of Securities specified in such Company Request
(except as to any surviving rights of registration of transfer or exchange of
Securities herein expressly provided for), and the Trustee, upon receipt of a
Company Order, and at the expense of the Company, shall execute proper
instruments in form and substance satisfactory to the Trustee and the Company
acknowledging satisfaction and discharge of this Indenture as to such series,
when:

          (1) either

              (A) all Securities of such series theretofore authenticated and
          delivered (other than (i) Securities which have been destroyed,
          lost or stolen and which have been replaced or paid as provided in
          Section 3.06 and (ii) Securities for whose payment money has
          theretofore been deposited in trust or segregated and held in trust
          by the Company and thereafter repaid to the Company or discharged
          from such trust, as provided in Section 10.03) have been delivered
          to the Trustee for cancellation; or

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

              (i) have become due and payable,

                                       33
<Page>

              (ii) will become due and payable at their Stated Maturity within
          one year, or

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

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

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

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

     Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Company to the Trustee under Section 6.07, the obligations of
the Company to any Authenticating Agent under Section 6.11 and, if money shall
have been deposited with the Trustee pursuant to subclause (B) of clause (1) of
this Section, the obligations of the Trustee under Section 4.02 and the last
paragraph of Section 10.03 shall survive.

     SECTION 4.02. APPLICATION OF TRUST MONEY.

     Subject to provisions of the last paragraph of Section 10.03, all money
deposited with the Trustee pursuant to Section 4.01 shall be held in trust and
applied by it, in accordance with the provisions of the Securities and this
Indenture, to the payment, either directly or through any Paying Agent
(including the Company acting as its own Paying Agent) as the Trustee may
determine, to the Persons entitled thereto, of the principal (and premium or
Make-Whole Amount, if any) and interest for whose payment such money has been
deposited with or received by the Trustee but such money need not be segregated
from other funds except to the extent required by law.

                           ARTICLE FIVE - REMEDIES

     SECTION 5.01. EVENTS OF DEFAULT.

     "Event of Default," wherever used herein with respect to Securities of any
series, and unless otherwise provided with respect to Securities of any series
pursuant to Section 3.01(12), means any one of the following events (whatever
the reason for such Event of Default and whether it shall be voluntary or
involuntary or be effected by operation of law or pursuant to any judgment,
decree or order of any court or any order, rule or regulation of any
administrative or governmental body):

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

                                       34
<Page>

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

          (3) default in the deposit of any sinking fund payment, when and as
     due by the terms of a Security of that series;

          (4) default in the performance, or breach, of any covenant or warranty
     of the Company in this Indenture with respect to any Security of that
     series (other than a covenant or warranty a default in whose performance or
     whose breach is elsewhere in this Section specifically dealt with or which
     has expressly been included in this Indenture solely for the benefit of
     series of one or more Securities other than that series), and continuance
     of such default or breach for a period of 60 days after there has been
     given, by registered or certified mail, to the Company by the Trustee or to
     the Company and the Trustee by the Holders of at least 25% in aggregate
     principal amount of the Outstanding Securities of that series a written
     notice specifying such default or breach and requiring it to be remedied
     and stating that such notice is a "Notice of Default" hereunder;

          (5) an event of default, as defined in any indenture or instrument
     under which the Company or a Principal Subsidiary Bank has at the date of
     this Indenture or shall hereafter have outstanding any indebtedness for
     borrowed money in an aggregate principal amount exceeding $5,000,000, shall
     happen and be continuing and such indebtedness shall either have become due
     and payable by its terms but not been paid or shall have been accelerated
     so that the same shall be or become due and payable prior to the date on
     which the same would otherwise have become due and payable and such payment
     default shall not be cured or such acceleration shall not be rescinded or
     annulled within 60 days after there has been given, by registered or
     certified mail, to the Company by the Trustee or to the Company and the
     Trustee by the Holders of at least 25% in aggregate principal amount of the
     Outstanding Securities of that series a written notice specifying such
     default or breach and requiring it to be remedied and stating that such
     notice is a "Notice of Default" hereunder, provided, however, that if,
     prior to a declaration of acceleration of the Maturity of the Securities of
     any series or the entry of judgment in favor of the Trustee in a suit
     pursuant to Section 5.03, such event of default under such indenture or
     instrument shall be remedied or cured by the Company or such Principal
     Subsidiary Bank or waived by the holders of such indebtedness, then the
     Event of Default hereunder by reason thereof shall be deemed likewise to
     have been thereupon remedied, cured or waived without further action upon
     the part of either the Trustee or any of the Holders of Securities of such
     series;

          (6) the entry by a court having jurisdiction in the premises of (A) a
     decree or order for relief in respect of the Company or a Principal
     Subsidiary Bank in an involuntary case or proceeding under any applicable
     federal or state bankruptcy, insolvency, reorganization or other similar
     law or (B) a decree or order adjudging the Company or a Principal
     Subsidiary Bank bankrupt or insolvent, or approving as properly filed a
     petition seeking reorganization, arrangement, adjustment or composition of
     or in respect of the Company or a Principal Subsidiary Bank under any
     applicable federal or state law, or appointing a custodian, receiver,
     liquidator, assignee, trustee, sequestrator or other similar official of
     the Company or a Principal Subsidiary Bank or of any substantial part of
     its property, or ordering the winding up or liquidation of its affairs, and
     the continuance of any such decree or order for relief or any such other
     decree or order unstayed and in effect for a period of 60 consecutive days;

          (7) the commencement by the Company or a Principal Subsidiary Bank of
     a voluntary case or proceeding under any applicable federal or state
     bankruptcy, insolvency, reorganization or other similar law or of any other
     case or proceeding to be adjudicated bankrupt

                                       35
<Page>

     or insolvent, or the consent by it to the entry of a decree or order for
     relief in respect of the Company or a Principal Subsidiary Bank in an
     involuntary case or proceeding under any applicable federal or state
     bankruptcy, insolvency, reorganization or other similar law or to the
     commencement of any bankruptcy or insolvency case or proceeding against it,
     or the filing by it of a petition or answer or consent seeking
     reorganization or relief under any applicable federal or state law, or the
     consent by it to the filing of such petition or to the appointment of or
     taking possession by a custodian, receiver, liquidator, assignee, trustee,
     sequestrator or other similar official of the Company or a Principal
     Subsidiary Bank or of any substantial part of its property, or the making
     by it of an assignment for the benefit of creditors, or the admission by it
     in writing of its inability to pay its debts generally as they become due,
     or the taking of corporate action by the Company or a Principal Subsidiary
     Bank in furtherance of any such action; or

          (8) any other Event of Default provided with respect to Securities of
that series.

     Upon receipt by the Trustee of any Notice of Default pursuant to Section
5.01 with respect to Securities of a series all or part of which is
represented by a Global Security, a record date shall be established for
determining Holders of Outstanding Securities of such series entitled to join
in such Notice of Default, which record date shall be at the close of
business on the date the Trustee receives such Notice of Default. The Holders
on such record date, or their duly designated proxies, and only such Persons,
shall be entitled to join in such Notice of Default, whether or not such
Holders remain Holders after such record date; provided, that unless Holders
of at least 10% in principal amount of the Outstanding Securities of such
series, or their proxies, shall have joined in such Notice of Default prior
to the day which is 90 days after such record date, such Notice of Default
shall automatically and without further action by any Holder be cancelled and
of no further effect. Nothing in this paragraph shall prevent a Holder, or a
proxy of a Holder, from giving, after expiration of such 90-day period, a new
Notice of Default which is identical to a Notice of Default which has been
cancelled pursuant to the proviso to the preceding sentence, in which event a
new record date shall be established pursuant to the provisions of this
Section 5.01.

     SECTION 5.02. ACCELERATION OF MATURITY; RESCISSION AND ANNULMENT.

     If an Event of Default with respect to Outstanding Securities of any series
occurs and is continuing, then and in every such case the Trustee or the Holders
of not less than 25% in aggregate principal amount of the Outstanding Securities
of that series may declare the principal amount (or, if any of the Securities of
that series are Original Issue Discount Securities, such lesser portion of the
principal amount of such Securities as may be specified in the terms thereof) of
all of the Securities of that series to be due and payable immediately, by a
notice in writing to the Company (and to the Trustee if given by Holders), and
upon any such declaration such principal amount (or specified portion thereof)
shall become immediately due and payable.

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

          (1) the Company has paid or deposited with the Trustee a sum
     sufficient to pay in the Required Currency (except as otherwise
     specified pursuant to Section 301 for the Securities of such series):

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

                                       36
<Page>

              (B) the principal of (and premium or Make-Whole Amount, if any,
          on) any Securities of that series which have become due otherwise than
          by such declaration of acceleration and interest thereon at the rate
          or rates prescribed therefor in such Securities,

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

              (D) all sums paid or advanced by the Trustee hereunder and the
          reasonable compensation, expenses, disbursements and advances of the
          Trustee, its agents and counsel, and any other amounts due the Trustee
          under Section 6.07;

          and

          (2) all Events of Default with respect to Securities of that series,
     other than the non-payment of the principal of (or premium or Make-Whole
     Amount, if any) or interest on Securities of that series which have become
     due solely by such declaration of acceleration, have been cured or waived
     as provided in Section 5.13.

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

     Upon receipt by the Trustee of any written notice declaring such an
acceleration, or rescission and annulment thereof, with respect to Securities of
a series all or part of which is represented by a Global Security, a record date
shall be established for determining Holders of Outstanding Securities of such
series entitled to join in such notice, which record date shall be at the close
of business on the day the Trustee receives such notice. The Holders on such
record date, or their duly designated proxies, and only such Persons, shall be
entitled to join in such notice, whether or not such Holders remain Holders
after such record date; provided, that unless such declaration of acceleration,
or rescission and annulment, as the case may be, shall have become effective by
virtue of the requisite percentage having joined in such notice prior to the day
which is 90 days after such record date, such notice of declaration of
acceleration, or rescission and annulment, as the case may be, shall
automatically and without further action by any Holder be cancelled and of no
further effect. Nothing in this paragraph shall prevent a Holder, or a proxy of
a Holder, from giving, after expiration of such 90-day period, a new written
notice of declaration of acceleration, or rescission or annulment thereof, as
the case may be, that is identical to a written notice which has been cancelled
pursuant to the proviso to the preceding sentence, in which event a new record
date shall be established pursuant to the provisions of this Section 5.02.

     SECTION 5.03. COLLECTION OF INDEBTEDNESS AND SUITS FOR ENFORCEMENT BY
TRUSTEE.

     The Company covenants that if,

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

          (2) default is made in the payment of the principal of (or premium or
     Make-Whole Amount, if any, on) any Security at the Maturity thereof, the
     Company will, upon demand of the Trustee, pay to it, for the benefit of the
     Holders of such Securities, the whole amount then due and payable on such
     Securities for principal (and premium or Make-Whole Amount, if any) and
     interest and, to the extent that payment of such interest shall be legally
     enforceable, interest on any overdue principal (and premium or Make-Whole
     Amount, if any) and on any overdue interest, at the rate or rates
     prescribed therefor in such Securities, and, in addition thereto, such

                                       37
<Page>

     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.

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

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

     SECTION 5.04. 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 or any other obligor upon the
Securities or the property of the Company or of such other obligor or their
creditors, the Trustee (irrespective of whether the principal of the Securities
of any series 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 for the payment of overdue principal premium,
Make-Whole Amount, if any or interest) shall be entitled and empowered, by
intervention in such proceeding or otherwise,

              (i) to file and prove a claim for the whole amount, or such lesser
          amount as may be provided for in the Securities of such series, of
          principal (and premium or Make-Whole Amount, if any) or such portion
          of the principal amount of any series of Original Issue Discount
          Securities as may be specified in the terms of such series and
          interest owing and unpaid in respect of the Securities and to file
          such other papers or documents as may be necessary or advisable in
          order to have the claims of the Trustee (including any claim for the
          reasonable compensation, expenses, disbursements and advances of the
          Trustee, its agents and counsel, and any other amounts due the Trustee
          under Section 6.07) and of the Holders 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 custodian, receiver, assignee, trustee. liquidator, sequestrator or
other similar official in any such judicial proceeding is hereby authorized by
each Holder to make such payments to the Trustee and, in the event that the
Trustee shall consent to the making of such payments directly to the Holders, to
pay to the Trustee any amount due it for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, and any other
amounts due the Trustee under Section 6.07.

     Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Holder any plan of
reorganization, arrangement, adjustment or composition affecting the Securities
or the rights of any Holder thereof or to authorize the Trustee to vote in
respect of the claim of any Holder in any such proceeding.

                                       38
<Page>

     In any proceedings brought by the Trustee (and also any proceedings
involving the interpretation of any provision of this Indenture to which the
Trustee shall be a party) the Trustee shall be held to represent all the
Holders, and it shall not be necessary to make any Holders parties to any such
proceedings.

     SECTION 5.05. TRUSTEE MAY ENFORCE CLAIMS WITHOUT POSSESSION OF SECURITIES.

     All rights of action and claims under this Indenture or the Securities may
be prosecuted and enforced by the Trustee without the possession of any of the
Securities or the production thereof in any proceeding relating thereto, and any
such proceeding instituted by the Trustee shall be brought in its own name as
trustee of an express trust, and any recovery of judgment shall, after provision
for the payment of the reasonable compensation, expenses. disbursements and
advances of the Trustee, its agents and counsel, and for any other amounts due
the Trustee under Section 6.07, be for the ratable benefit of the Holders of the
Securities in respect of which such judgment has been recovered.

     SECTION 5.06. APPLICATION OF MONEY COLLECTED.

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

          FIRST: To the payment of all amounts due the Trustee under
     Section 6.07;

          SECOND: To the payment of the amounts then due and unpaid for
     principal of (and premium or Make-Whole Amount, if any) and interest on the
     Securities 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 aggregate amounts due and payable on such Securities for
     principal (and premium or Make-Whole Amount, if any) and interest,
     respectively; and

          THIRD: The balance, if any, to the Person or Persons entitled thereto.

     SECTION 5.07. LIMITATION ON SUITS.

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

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

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

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

                                       39
<Page>

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

it being understood and intended that no one or more of such Holders shall have
any right in any manner whatever by virtue of, or by availing of, any provision
of this Indenture to affect, disturb or prejudice the rights of any other of
such Holders, or to obtain or to seek to obtain priority or preference over any
other of such Holders or to enforce any right under this Indenture, except in
the manner herein provided and for the equal and ratable benefit of all of such
Holders.

     SECTION 5.08. UNCONDITIONAL RIGHT OF HOLDERS TO RECEIVE PRINCIPAL, PREMIUM
AND INTEREST.

     Notwithstanding any other provision in this Indenture, the Holder of any
Security shall have the right, which is absolute and unconditional, to receive
payment of the principal of (and premium or Make-Whole Amount, if any) and
(subject to Section 3.07) interest on such Security on the Stated Maturity or
Maturities expressed in such Security (or, in the case of redemption, on the
Redemption Date) and to institute suit for the enforcement of any such payment,
and such rights shall not be impaired without the consent of such Holder.

     SECTION 5.09. RESTORATION OF RIGHTS AND REMEDIES.

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

     SECTION 5.10. RIGHTS AND REMEDIES CUMULATIVE.

     Except as otherwise provided with respect to the replacement or payment of
mutilated, destroyed, lost or stolen Securities in the last paragraph of
Section 3.06, no right or remedy herein conferred upon or reserved to the
Trustee or to the Holders is intended to be exclusive of any other right or
remedy, and every right and remedy shall, to the extent permitted by law, be
cumulative and in addition to every other right and remedy given hereunder or
now or hereafter existing at law or in equity or otherwise. The assertion or
employment of any right or remedy hereunder, or otherwise, shall not prevent the
concurrent assertion or employment of any other appropriate right or remedy.

     SECTION 5.11. DELAY OR OMISSION NOT WAIVER.

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

     SECTION 5.12. CONTROL BY HOLDERS.

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

                                       40
<Page>

remedy available to the Trustee, or exercising any trust or power conferred on
the Trustee, with respect to the Securities of such series, provided that,

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

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

     Upon receipt by the Trustee of any written notice directing the time,
method or place of conducting any such proceeding or the exercise of any such
trust or power with respect to Securities of a series all or part of which is
represented by a Global Security, a record date shall be established for
determining Holders of Outstanding Securities of such series entitled to join in
such notice, which record date shall be at the close of business on the day the
Trustee receives such notice. The Holders on such record date, or their duly
designated proxies, and only such Persons, shall be entitled to join in such
notice, whether or not such Holders remain after such record date; provided,
that unless Holders of a majority (or, in the case of Section 5.07(2), 25%) in
principal amount of the Outstanding Securities of such series shall have joined
in such notice prior to the day which is 90 days after such record date, such
notice shall automatically and without further action by any Holder be cancelled
and of no further effect. Nothing in this paragraph shall prevent a Holder, or a
proxy of a Holder, from giving, after expiration of such 90-day period, a new
notice identical to a notice which has been cancelled pursuant to the proviso to
the preceding sentence, in which event a new record date shall be established
pursuant to the provisions of this Section 5.12.

     SECTION 5.13. WAIVER OF PAST DEFAULTS.

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

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

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

     The Company may, but shall not be obligated to, fix a record date for the
purpose of determining the Persons entitled to waive any past default hereunder.
If a record date is fixed, the Holders on such record date, or their duly
designated proxies, and only such Persons, shall be entitled to waive any
default hereunder, whether or not such Holders remain Holders after such record
date; provided, that unless such majority in principal amount shall have waived
such default prior to the date which is 90 days after such record date, any such
waiver of such default previously given shall automatically and without further
action by any Holder be cancelled and of no further effect.

     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.

                                       41
<Page>

     SECTION 5.14. UNDERTAKING FOR COSTS.

     All parties to this Indenture agree, and each Holder of any Security by his
acceptance thereof shall be deemed to have agreed, that any court may in its
discretion require, in any suit for the enforcement of any right or remedy under
this Indenture, or in any suit against the Trustee for any action taken,
suffered or omitted by it as Trustee, 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; provided,
however, that the provisions of this Section shall not apply to any suit
instituted by the Company, to any suit instituted by the Trustee, to any suit
instituted by any Holder, or group of Holders, holding in the aggregate more
than 10% in principal amount of the Outstanding Securities of any series, or to
any suit instituted by any Holder for the enforcement of the payment of the
principal of (or premium, if any) or interest on any Security on or after the
Stated Maturity or Maturities expressed in such Security (or, in the case of
redemption, on or after the Redemption Date).

     SECTION 5.15. WAIVER OF STAY OR EXTENSION LAWS.

     The Company covenants (to the extent that it may lawfully do so) that it
will not at any time insist upon, or plead, or in any manner whatsoever claim or
take the benefits or advantages 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 (to the extent that it may
lawfully do so) hereby expressly waives all benefits or advantages 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.

     SECTION 6.01. CERTAIN DUTIES AND RESPONSIBILITIES.

     The provisions of TIA Section 315 shall apply to the Trustee.

     SECTION 6.02. NOTICE OF DEFAULTS.

to the Securities of any series, the Trustee shall transmit by mail to all
Holders of Securities 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 or
Make-Whole Amount, if any) or interest on any Security of such series or in the
payment of any sinking fund installment 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 Holders of
Securities of such series; and provided, further, that in the case of any
default of the character specified in Section 5.01(4) with respect to Securities
of such series, no such notice to Holders shall be given until at least 30 days
after the occurrence thereof. For the purpose of this Section, the term
"default" means any event which is, or after notice or lapse of time or both
would become, an Event of Default with respect to Securities of such series.

rely upon an Officers' Certificate;

expenses and liabilities which might be incurred by it in compliance with such

provision of this Indenture indicates that any confirmation of a condition or
event is qualified by the words "to the knowledge of the Trustee" or "known
to the Trustee" or "of which the Trustee actually knows" or other words of

     The recitals contained herein and in the Securities, except the Trustee's

     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

instrument of acceptance by a successor Trustee required by Section 6.11 shall
not have been delivered to the Trustee within 30 days after the giving of such
notice of resignation, the resigning Trustee may petition any court of competent
jurisdiction for the appointment of a successor Trustee with respect to the
Securities of such series.

          (c) The Trustee may be removed at any time with respect to the
Securities of any series by an Act of the Holders of a majority in principal
amount of the Outstanding Securities of such series, delivered to the Trustee
and to the Company. If an instrument of acceptance by a successor Trustee shall
not have been delivered to the Trustee within 30 days after the removal of the
Trustee, the Trustee being removed may petition at the expense of the Company
any court of competent jurisdiction for the appointment of a successor Trustee.

          (d) If at any time:

          shall fail to resign after written request therefor by the Company or
          by any such Holder, or

              (3) the Trustee shall become incapable of acting or shall be
          adjudged 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 or pursuant to a Board Vote may
remove the Trustee with respect to all Securities, or (ii) subject to
Section 5.14, any Holder who has been a bona fide Holder of a

                                       45
<Page>

Security for at least six months may, on behalf of himself and all others
similarly situated, petition any court of competent jurisdiction for the removal
of the Trustee with respect to all Securities and the appointment of a successor
Trustee or Trustees.

          (e) If the Trustee shall resign, be removed or become incapable of
acting, or if a vacancy shall occur in the office of Trustee for any cause, with
respect to the Securities of one or more series, the Company, by or pursuant to
a Board Vote, shall promptly appoint a successor Trustee or Trustees with
respect to the Securities of that or those series (it being understood that any
such successor Trustee may be appointed with respect to the Securities of one or
more or all of such series and that at any time there shall be only one Trustee
with respect to the Securities of any particular series) and shall comply with
the applicable requirements of Section 6.11. If, within one year after such
resignation, removal or incapability, or the occurrence of such vacancy, a
successor Trustee with respect to the Securities of any series shall be
appointed by Act of the Holders of a majority in principal amount of the
Outstanding Securities of such series delivered to the Company and the retiring
Trustee, the successor Trustee so appointed shall, forthwith upon its acceptance
of such appointment in accordance with the applicable requirements of
Section 6.11, become the successor Trustee with respect to the Securities of
such series and to that extent supersede the successor Trustee appointed by the
Company. If no successor Trustee with respect to the Securities of any series
shall have been so appointed by the Company or the Holders and accepted
appointment in the manner required by Section 6.11, any Holder who has been a
bona fide Holder of a Security of such series for at least six months may, on
behalf of himself and all others similarly situated, petition any court of
competent jurisdiction for the appointment of a successor Trustee with respect
to the Securities of such series.

          (f) The Company shall give notice of each resignation and each removal
of the Trustee with respect to the Securities of any series and each appointment
of a successor Trustee with respect to the Securities of any series in the
manner provided for notices in Section 1.06 to all Holders of Securities of such
series as their names and addresses appear in the Security Register. Each notice
shall include the name of the successor Trustee with respect to the Securities
of such series and the address of its Corporate Trust Office.

     SECTION 6.11. ACCEPTANCE OF APPOINTMENT BY SUCCESSOR.

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

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

                                       46
<Page>

Trustee with respect to the Securities of that or those series as to which the
retiring Trustee is not retiring shall continue to be vested in the retiring
Trustee, and (3) shall add to or change any of the provisions of this Indenture
as shall be necessary to provide for or facilitate the administration of the
trusts hereunder by more than one Trustee, it being understood that nothing
herein or in such supplemental indenture shall constitute such Trustees
co-trustees of the same trust and that each such Trustee shall be trustee of a
trust or trusts hereunder separate and apart from any trust or trusts hereunder
administered by any other such Trustee and upon the execution and delivery of
such supplemental indenture the resignation or removal of the retiring Trustee
shall become effective to the extent provided therein and each such successor
Trustee, without any further act, deed or conveyance, shall become vested with
all the rights, powers, trusts and duties of the retiring Trustee with respect
to the Securities of that or those series to which the appointment of such
successor Trustee relates; but, on request of the Company or any successor
Trustee, such retiring Trustee shall duly assign, transfer and deliver to such
successor Trustee all property and money held by such retiring Trustee hereunder
with respect to the Securities of that or those series to which the appointment
of such successor Trustee relates. Whenever there is a successor Trustee with
respect to one or more (but less than all) series of securities issued pursuant
to this Indenture, the terms "Indenture" and "Securities" shall have the
meanings specified in the provisos to the respective definitions of those terms
in Section 1.01 which contemplate such situation.

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

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

          (e) Notwithstanding anything else herein contained, the parties
further acknowledge and agree that any Trustee which has resigned or been
removed pursuant to the terms of this Indenture (the "Prior Trustee") shall
continue to have a lien prior to the Securities on all money or property held
or collected by any successor Trustee (other than money or property held in
trust to pay the principal of, premium and Make Whole Amount, if any, and
interest on particular Securities) in accordance with Section 6.07 of this
Indenture (collectively, the "Available Trust Property") as security for
payment of all amounts due and owing to the Prior Trustee which have not been
paid by the Company (collectively, the "Prior Trustee's Receivables") and
that such lien shall survive the resignation or removal of the Prior Trustee.
Any successor Trustee agrees to hold on a parity basis all Available Trust
Property subject to such lien in trust for the benefit of the Prior Trustee
and itself for the purpose of paying all of the Prior Trustee's Receivables
and all amounts owed to the successor Trustee under and by virtue of this
Indenture. By accepting its appointment as Trustee hereunder, the successor
Trustee further agrees to execute and deliver such further instruments and
shall do such other things as the Prior Trustee may reasonably require so as
to more fully and certainly vest and confirm in the Prior Trustee said parity
lien on and rights to the Available Trust Property. In furtherance of the
foregoing, except with the specific written consent of the Prior Trustee, the
successor Trustee shall not waive, compromise or otherwise impair, directly
or indirectly, the Prior Trustee's rights to enforce such lien with respect
to the Prior Trustee's Receivables.

     SECTION 6.12. 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 to whom all or substantially all the corporate trust business
of the Trustee shall be transferred, shall be the successor of the Trustee
hereunder, provided such Corporation shall be otherwise qualified and
eligible under this Article, without the execution or filing of any paper or
any further act on the part of any of the parties hereto. In case any
Securities shall have been authenticated, but not delivered, by the Trustee
then in office, any successor by merger, conversion, consolidation, or
transfer of all or substantially all of the corporate trust business of the
Trustee, to such authenticating Trustee may adopt such authentication and
deliver the Securities so authenticated with the same effect as if such
successor Trustee had itself authenticated such Securities; in case any of
the Securities shall not have been authenticated by the Trustee then in
office, any successor to such Trustee by merger, conversion, consolidation,
or transfer of all or substantially all of the corporate trust business of
the Trustee,  may authenticate such Securities either in the name of such
predecessor hereunder or in the name of the successor Trustee; and in all
such cases such certificates shall have the full force which it is anywhere
in the Securities or in this Indenture provided that the certificate of the
Trustee shall have; provided, however, that the right to adopt the
certificate of authentication of any predecessor Trustee or to authenticate
Securities in the name of any predecessor Trustee shall apply only to its
successor or successors by merger, conversion, consolidation, or transfer of
all or substantially all of the corporate trust business of the Trustee.

     SECTION 6.13. PREFERENTIAL COLLECTION OF CLAIMS AGAINST COMPANY.

     The Trustee shall comply with TIA Section 311(a). A Trustee which has
resigned or been removed is subject to TIA Section 311(a) to the extent
indicated therein.

                                       47

     SECTION 6.14.APPOINTMENT OF AUTHENTICATING AGENT.

     At any time when any of the Securities remain Outstanding the Trustee,
with the concurrence of the Company, may appoint an Authenticating Agent or
Agents with respect to one or more series of Securities which shall be
authorized to act on behalf of the Trustee to authenticate Securities of such
series, and Securities so authenticated shall be entitled to the benefits of
this Indenture and shall be valid and obligatory for all purposes as if
authenticated by the Trustee hereunder. Any such appointment shall be
evidenced by an instrument in writing signed by a Responsible Officer of the
Trustee, a copy of which instrument shall be promptly furnished to the
Company. 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 bank or trust Company or Corporation
organized and doing business under the laws of the United States of America,
any State thereof or the District of Columbia authorized under such laws to
act as Authenticating Agent, having a combined capital and surplus of not
less than $50,000,000 and subject to supervision or examination by Federal,
State or District of Columbia authority. If such Authenticating Agent files
reports of condition at least annually, pursuant to law or to the
requirements of said supervising or examining authority, then for the
purposes of this Section, the combined capital and surplus of such
Authenticating Agent shall be deemed to be its combined capital and surplus
as set forth in its most recent report of condition so filed. If at any time
an Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, such Authenticating Agent shall resign
immediately in the manner and with the effect specified in this Section.

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

     An Authenticating Agent may resign at any time by giving written notice
thereof to the Trustee and to the Company. The Trustee may at any time terminate
the agency of an Authenticating Agent by giving written notice thereof to such
Authenticating Agent and to the Company. Upon receiving such a notice of
resignation or upon such a termination, or in case at any time such
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, the Trustee may appoint a successor Authenticating
Agent which shall be acceptable to the Company and shall 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 Company agrees to pay to each Authenticating Agent from time to time
reasonable compensation for its services under this Section.

     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 substantially in the following form:

                                       48
<Page>

     This is one of the Securities of the series designated herein and issued
pursuant to the within-mentioned Indenture.

                                         Authorized Officer

        SECTION 6.15.  PROVISIONS FOR SEPARATE TRUSTEES AND CO-TRUSTEES.

     At any time or times, for the purpose of conforming to any legal
requirements, restrictions or conditions in any State or jurisdiction in
which any part of any mortgaged and pledged property then subject to this
Indenture may be located or for any other reason, the Company and the Trustee
shall have power to appoint, and, upon the request of the Trustee, the
Company shall for such purpose join with the Trustee in the execution,
delivery and performance of, all instruments and agreements necessary or
proper to appoint another corporation or one or more persons approved by the
Trustee, either to act as separate trustee or trustees, or co-trustee or
co-trustees jointly with the Trustee, with respect to this Indenture and any
of the property subject to the lien hereof. In the event that the Company
shall not have joined in such appointment within 15 days after the receipt by
it of a request so to do, the Trustee alone shall have power to make such
appointment.

     Every separate trustee, every co-trustee and every successor trustee,
other than any trustee which may be appointed as successor to shall, to the
extent permitted by law, but to such extent only, be appointed subject to the
following provisions and conditions, namely:

          (1) The rights, powers, duties and obligations conferred or imposed
upon trustees hereunder or any of them shall be conferred or imposed upon and
exercised or performed by the Trustee or the Trustees and such separate
trustee or separate trustees or co-trustee or co-trustees jointly, as shall
be provided in the supplemental indenture appointing such separate trustee or
separate trustees or co-trustee or co-trustees, except to the extent that
under any law of any jurisdiction in which any particular act or acts are to
be performed the Trustee shall be incompetent or unqualified to perform such
act or acts, in which event such rights, powers, duties and obligations shall
be exercised and performed by such separate trustee or separate trustees or
co-trustee or co-trustees.

          (2) The Securities secured hereby shall be authenticated and
delivered, and all powers, duties, obligations and rights, conferred upon the
Trustee in respect of the custody of the Securities and of all cash and
investments pledged or deposited hereunder, shall be exercised solely by the
Trustee or its successor in the trust hereunder.

          (3) The Company and the Trustee, at any time by an instrument in
writing executed by them jointly, may accept the resignation of or remove any
separate trustee or co-trustee appointed under this Section or otherwise,
and, upon the request of the Trustee, the Company shall, for such purpose,
join with the Trustee in the execution, delivery and performance of all
instruments and agreements necessary or proper to make effective such
resignation or removal. In the event that the Company shall not have joined
in such action with 15 days after the receipt of it of a request so to do,
the Trustee alone shall have power to accept such resignation or to remove
any such separate trustee or co-trustee. A successor to a separate trustee or
co-trustee so resigned or removed may be appointed in the manner provided in
this Section.

          (4) No trustee hereunder shall be personally liable by reason of
any act or omission of any other trustee hereunder.

     Any notice, request or other writing, by or on behalf of the holders of
the Securities delivered to the Trustee, or its successor in the trust
hereunder, shall be deemed to have been delivered to all of the then trustees
or co-trustees as effectively as if delivered to each of them. Every
instrument appointing any trustee or trustees other than a successor to the
Trustee shall refer to this Indenture and the conditions in this Article
expressed, and upon the acceptance in writing by such trustee or trustees or
co-trustee or co-trustees, he, they or it shall be vested with the estates or
property specified in such instrument, either jointly with the Trustee or its
successor, or separately, as may be provided therein, subject to all the
trusts, conditions and provisions of this Indenture; and every such
instrument shall be filed with the Trustee or its successor in the trust
hereunder. Any separate trustee or trustees, or any co-trustee or
co-trustees, may at any time by an instrument in writing constitute the
Trustee or its successor in the trust hereunder his, their or its agent or
attorney-in-fact, with full power and authority, to the extent which may be
permitted by law, to do all acts and things and exercise all discretion
authorized or permitted by him, them or it, for and in behalf of him, them or
it, and in his, their or its name. In case any separate trustee or trustees
or co-trustee or co-trustees, or a successor to any of them, shall die,
become incapable of acting, resign or be removed, all the estates, property,
rights, powers, trusts, duties and obligations of said separate trustee or
co-trustee, so far as permitted by law, shall vest in and be exercised by the
Trustee or its successor in the trust hereunder, without the appointment of a
new trustee as successor to such separate trustee or co-trustee.

respect to their rights under this Indenture or under the Securities, and the
corresponding rights and privileges of the Trustee, shall be as provided by TIA
Section 312(b).

          (c) Every Holder of Securities, by receiving and holding the same,

disclosure of any such information as to the names and addresses of the Holders
in accordance with Section 7.02(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 7.02(b).

     particular period of grace after default (which period may be shorter or
     longer than that allowed in the case of other defaults) or may provide for
     an immediate enforcement upon such default or may limit the remedies
     available to the Trustee upon such default or may limit the right of the
     Holders of a majority in aggregate principal amount of that or those series
     of Securities to which such additional Events of Default apply to waive
     such default;

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

          (5) to secure the Securities;

          (6) to establish the form or terms of Securities of any series as
     permitted by Sections 2.01 and 3.01;

          (7) to evidence and provide for the acceptance of appointment
     hereunder by a successor Trustee with respect to the Securities of one or
     more series and to add to or change any of the provisions of this Indenture
     as shall be necessary to provide for or facilitate the administration of
     the trusts hereunder by more than one Trustee, pursuant to the requirements
     of Section 6.11(b);

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

                                       52
<Page>

          (9) to make provisions with respect to Holders' rights of conversion
with respect to any series of Securities pursuant to Article Fifteen.

     Notwithstanding any provision in this Indenture or otherwise, the rights
of creditors in respect of General Obligations under this Indenture and
otherwise in respect of the Securities may, at any time and from time to
time, be reduced or eliminated by a supplemental indenture entered into by
the Company and the Trustee, which supplemental indenture will not require
the consent of the Holders of Securities or any creditor in respect of
General Obligations.

     SECTION 9.02. SUPPLEMENTAL INDENTURES WITH CONSENT OF HOLDERS.

     With the consent of the Holders of not less than a majority in aggregate
principal amount of the Outstanding Securities of each series affected by
such supplemental indenture, by Act of said Holders delivered to the Company
and the Trustee, the Company, when authorized by a Board Vote, 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 Securities of such series under this Indenture;
provided, however, that no such supplemental indenture shall, without the
consent of the Holder of each Outstanding Security affected thereby,

          (1) change the Stated Maturity of the principal of, or any installment
     of principal of or interest on, any such Security, or reduce the principal
     amount thereof or the rate of interest thereon or any premium payable upon
     the redemption thereof, or reduce the amount of the principal of an
     Original Issue Discount Security that would be due and payable upon a
     declaration of acceleration of the Maturity thereof pursuant to
     Section 5.02, or change any Place of Payment where, or the coin or currency
     in which, any such Security or any premium or the interest thereon is
     payable, or impair the right to institute suit for the enforcement of any
     such payment on or after the Stated Maturity thereof (or, in the case of
     redemption, on or after the Redemption Date),

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

          (3) modify any of the provisions of this Section, Section 5.13 or
     Section 10.09, except to increase any such percentage or to provide that
     certain other provisions of this Indenture cannot be modified or waived
     without the consent of the Holder of each Outstanding Security affected
     thereby, provided, however, that this clause shall not be deemed to require
     the consent of any Holder with respect to changes in the references to "the
     Trustee" and concomitant changes in this Section and Section 10.09 or the
     deletion of this proviso, in accordance with the requirements of
     Sections 6.11(b) and 9.01(8).

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.

     The Company may, but shall not be obligated to, fix a record date for the
purpose of determining the Persons entitled to consent to any indenture
supplemental hereto. If a record date is fixed for such purpose, the Holders on
such record date or their duly designated proxies, and only such Persons, shall
be entitled to consent to such supplemental indenture, whether or not such
Holders remain Holders after such record date; provided, that unless such
consent shall have become effective by virtue of the requisite percentage having
been obtained prior to the date which is 90 days after such record date, any
such consent previously given shall automatically and without further action by
any Holder be cancelled and of no further effect.

                                       53
<Page>

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

     SECTION 9.03.EXECUTION OF SUPPLEMENTAL INDENTURES.

     In executing or accepting the additional trusts created by, any
supplemental indenture permitted by this Article or the modifications thereby
of the trusts created by this Indenture, the Trustee shall be entitled to
receive, and (subject to Section 6.01) shall be fully protected in relying
upon, an Opinion of Counsel stating that the execution of such supplemental
indenture is authorized or permitted by this Indenture. The Trustee may, but
shall not be obligated to, enter into any such supplemental indenture which
affects the Trustee's own rights, duties, protections, privileges,
indemnities, liabilities, or immunities under this Indenture or otherwise.

     SECTION 9.04. EFFECT OF SUPPLEMENTAL INDENTURES.

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

     SECTION 9.05. CONFORMITY WITH TRUST INDENTURE ACT.

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

     SECTION 9.06. REFERENCE IN SECURITIES TO SUPPLEMENTAL INDENTURES.

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

     SECTION 9.07. NOTICE OF SUPPLEMENTAL INDENTURES.

     Promptly after the execution by the Company and the Trustee of any
supplemental indenture pursuant to the provisions of Section 9.02, the Company
shall give notice thereof to the Holders of each Outstanding Security so
affected, pursuant to Section 1.06, setting forth in general terms the substance
of such supplemental indenture.

                             ARTICLE TEN - COVENANTS

     SECTION 10.01. PAYMENT OF PRINCIPAL, PREMIUM AND INTEREST.

     The Company covenants and agrees for the benefit of each series of
Securities that it will duly and punctually pay the principal of (and
premium, if any) and interest on the Securities of that series in accordance
with the terms of the Securities and this Indenture.

                                       54
<Page>

In the absence of contrary provisions with respect to the Securities of any
series, interest on the Securities of any series may, at the option of the
Company, be paid by check mailed to the address of the Person entitled
thereto as it appears on the Security Register.

     SECTION 10.02. MAINTENANCE OF OFFICE OR AGENCY.

     The Company will maintain in each Place of Payment for any series of
Securities an office or agency where Securities of that series may be presented
or surrendered for payment, where Securities of that series may be surrendered
for registration of transfer or exchange and where notices and demands to or
upon the Company in respect of the Securities of that series and this Indenture
may be served. The Company 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 Company shall fail to maintain any such required office or agency or shall
fail to furnish the Trustee with the address thereof, such presentations,
surrenders, notices and demands may be made or served at the Corporate Trust
Office of the Trustee, and the Company hereby appoints the Trustee as its agent
to receive all such presentations, surrenders, notices and demands.

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

     SECTION 10.03. MONEY FOR SECURITIES PAYMENTS TO BE HELD IN TRUST.

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

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

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

          (1) hold all sums held by it for the payment of the principal of (and
     premium, if any) or interest on Securities of that 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;

                                       55
<Page>

          (2) give the Trustee notice of any default by the Company (or any
     other obligor upon the Securities of that series) in the making of any
     payment of principal (and premium, if any) or interest on the Securities of
     that 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 may at any time, for the purpose of obtaining the satisfaction
and discharge of this Indenture or for any other purpose, pay, or by Company
Order direct any Paying Agent to pay, to the Trustee all sums held in trust by
the Company or such Paying Agent, such sums to be held by the Trustee upon the
same trusts as those upon which such sums were held by the Company or such
Paying Agent; and, upon such payment by 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, in trust for the payment of the principal of (and premium or
Make-Whole Amount, if any) or interest on any Security of any series and
remaining unclaimed for two years after such principal (and premium or
Make-Whole Amount, if any) or interest has become due and payable shall be paid
to the Company on Company Request, or (if then held by the Company) shall be
discharged from such trust; and the Holder of such Security shall thereafter, as
an unsecured general creditor, look only to the Company for payment thereof, and
all liability of the Trustee or such Paying Agent with respect to such trust
money, and all liability of the Company as trustee thereof, shall thereupon
cease; provided, however, that the Trustee or such Paying Agent, before being
required to make any such repayment, may at the expense of the Company cause to
be published once, in a newspaper published in the English language, customarily
published on each Business Day and of general circulation in the City of New
York, notice that such money remains unclaimed and that, after a date specified
therein, which shall not be less than 30 days from the date of such publication,
any unclaimed balance of such money then remaining will be repaid to the
Company.

     SECTION 10.04. EXISTENCE.

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

     SECTION 10.05. MAINTENANCE OF PROPERTIES.

     The Company will cause all of its material properties used or useful in the
conduct of its business or the business of any Subsidiary to be maintained and
kept in good condition, repair and working order and supplied with all necessary
equipment and will cause to be made all necessary repairs, renewals,
replacements, betterments and improvements thereof, all as in the judgment of
the Company may be necessary so that the business carried on in connection
therewith may be properly and advantageously conducted at all times; provided,
however, that nothing in this Section shall prevent the Company from
discontinuing the operation or maintenance of any of such properties if such
discontinuance is, in the judgment of the Company, desirable in the conduct of
its business or the business of any Subsidiary and not disadvantageous in any
material respect to the Holders.

                                       56
<Page>

     SECTION 10.06. PAYMENT OF TAXES AND OTHER CLAIMS.

     The Company will pay or discharge or cause to be paid or discharged, before
the same shall become delinquent, (1) all taxes, assessments and governmental
charges levied or imposed upon the Company or any Subsidiary or upon the income,
profits or property of the Company or any Subsidiary, and (2) all lawful claims
for labor, materials and supplies which, if unpaid, might by law become a lien
upon the property of the Company or any Subsidiary; provided, however, that the
Company shall not be required to pay or discharge or cause to be paid or
discharged any such tax, assessment, charge or claim whose amount, applicability
or validity is being contested in good faith by appropriate proceedings.

     SECTION 10.07. LIMITATIONS ON DISPOSITION OF VOTING STOCK OF PRINCIPAL
SUBSIDIARY BANKS.

     Subject to Section 8.01, the Company will not (a) issue, sell or otherwise
dispose of any shares of or securities convertible into, or options, warrants or
rights to subscribe for or purchase shares of, Voting Stock of a Principal
Subsidiary Bank or permit a Principal Subsidiary Bank so to do, (b) permit the
merger or consolidation of any Principal Subsidiary Bank with or into any other
Corporation or (c) permit the sale or other disposition of all or substantially
all of the assets of a Principal Subsidiary Bank if, after giving effect to any
such transaction and the issuance of the maximum number of shares of Voting
Stock issuable upon the conversion or exercise of all such convertible
securities, options, warrants or rights, the Company would own, directly or
indirectly, 80% or less of the shares of Voting Stock of such Principal
Subsidiary Bank or the successor bank in such merger or consolidation or the
bank which acquires such assets, as the case may be.

     SECTION 10.08. RESTRICTIONS ON LIENS.

     The Company will not create, assume, incur or suffer to exist any pledge,
encumbrance or lien, as security for indebtedness for borrowed money, upon any
shares of, or securities convertible into, or options, warrants or rights to
subscribe for or purchase shares of, Voting Stock of a Principal Subsidiary
Bank, owned by the Company, directly or indirectly, without making effective
provision whereby the Securities of all series shall be equally and ratably
secured, if, treating such pledge, encumbrance or lien as a transfer to the
secured party, and after giving effect to the issuance of the maximum number of
shares of Voting Stock issuable upon conversion or exercise of such convertible
securities, options, warrants or rights, the Company would own, directly or
indirectly, 80% or less of the shares of Voting Stock of such Principal
Subsidiary Bank.

     SECTION 10.09. WAIVER OF CERTAIN COVENANTS.

     The Company may omit in any particular instance to comply with any term,
provision or condition set forth in Sections 10.04 to 10.08, inclusive, with
respect to the Securities of any series if before the time for such compliance
the Holders of not less than a majority in aggregate principal amount of the
Outstanding Securities of such series shall, by Act of such Holders, either
waive such compliance in such instance or generally waive compliance with such
term, provision or condition, but no such waiver shall extend to or affect such
term, provision or condition except to the extent so expressly waived, and,
until such waiver shall become effective, the obligations of the Company and the
duties of the Trustee in respect of any such term, provision or condition shall
remain in full force and effect.

     The Company may, but shall not be obligated to, fix a record date for the
purpose of determining the Persons entitled to waive any such term, provision or
condition. If a record date is fixed for such purpose, the Holders on such
record date or their duly designated proxies, and only such Persons, shall be
entitled to waive any such term, provision or condition hereunder whether or not
such Holders remain

                                       57
<Page>

Holders after such record date; provided, that unless the Holders of not less
than a majority in principal amount of the Outstanding Securities of such series
shall have waived such term, provision or condition prior to the date which is
90 days after such record date, any such waiver previously given shall
automatically and without further action by any Holder be cancelled and of no
further effect.

                    ARTICLE ELEVEN - REDEMPTION OF SECURITIES

     SECTION 11.01. APPLICABILITY OF ARTICLE.

     Securities of any series which are redeemable before their Stated Maturity

     SECTION 11.02. ELECTION TO REDEEM; NOTICE TO TRUSTEE.

     The election of the Company to redeem Securities of any series shall be
evidenced by an Officers' Certificate. The Company shall, at least 60 days prior

satisfactory to the Trustee), notify the Trustee of:

          (1) such Redemption Date,

          (2) if the Securities of such series have different terms and less
     than all of the Securities of such series are to be redeemed, the terms of
     the Securities to be redeemed, and

          (3) if less than all the Securities of such series with identical
     terms are to be redeemed, the principal amount of such Securities to be
     redeemed.

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

     SECTION 11.03. SELECTION BY TRUSTEE OF SECURITIES TO BE REDEEMED.

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 like tenor of such series not previously called for redemption, by
such method as the Trustee shall deem fair and appropriate and which may provide
for the selection for redemption of portions (equal to the minimum authorized
denomination for Securities of like tenor of that series or any integral
multiple thereof) of the principal amount of Securities of such series of a
denomination larger than the minimum authorized denomination for Securities of
that series.

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

     For all purposes of this Indenture, unless the context otherwise requires,
all provisions relating to the redemption of Securities shall relate, in the
case of any Securities redeemed or to be redeemed only in part, to the portion
of the principal amount of such Securities which has been or is to be redeemed.

shorter period is specified by the terms of such series established pursuant to
Section 3.01, to each Holder of Securities to be redeemed, at his address
appearing in the Security Register, but failure to give such notice in the
manner herein provided to the Holder of any Security designated for redemption
as a whole or in part, or any defect in the notice to any such Holder, shall not
affect the validity of the proceedings for the redemption of any other such
Security or portion thereof.

     redeemed,

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

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

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

          (7) the CUSIP number of such Security, if any, and

          (8) if applicable, that a Holder who desires to convert Securities
     for redemption must satisfy the requirements for conversion contained in
     such Securities, the then existing conversion price or rate, the place
     or places where such Securities may be surrendered for conversion, and

     On or prior to 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 10.03 ) an amount of
money in immediately available funds sufficient to pay the Redemption Price of,
and (except if the Redemption Date shall be an Interest Payment Date) accrued
interest on, all the Securities which are to be redeemed on that date.

     If any Securities called for redemption are converted, any money deposited
with the Trustee or with any Paying Agent or so segregated and held in trust for
the redemption of such Security shall be paid to the Company upon Company
Request or, if then held by the Company, shall be discharged from such trust.

     SECTION 11.06. SECURITIES PAYABLE ON REDEMPTION DATE.

interest) such Securities shall cease to bear interest. Upon surrender of any
such Security for redemption in accordance with said notice, such Security shall
be paid by the Company at the Redemption Price, together with accrued interest
to the Redemption Date; provided, however, that, unless otherwise specified as
contemplated by Section 3.01, installments of interest whose Stated Maturity is
on or prior to the Redemption Date shall be payable to the Holders of such
Securities, or one or more Predecessor Securities, registered as such at the
close of business on the relevant Regular Record Dates according to their terms
and the provisions of Section 3.07.

     If any Security called for redemption shall not be so paid upon surrender
thereof for redemption, the principal (and premium or Make-Whole Amount, if any)
shall, until paid, bear interest from the Redemption Date at the rate prescribed
therefor in the Security.

     SECTION 11.07. SECURITIES REDEEMED IN PART.

     Any Security which is to be redeemed in part shall be surrendered at a
Place of Payment for such series (with, if the Company or the Trustee so
requires, due endorsement by, or a written instrument of transfer in form
satisfactory to the Company and the Trustee duly executed by, the Holder thereof
or 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 of
like tenor, of any authorized denomination as requested by such Holder, in
aggregate principal amount equal to and in exchange for the unredeemed portion
of the principal of the Security so

                                       60
<Page>

surrendered; provided, however, that if a Global Security is so surrendered,
such new Security so issued shall be a new Global Security in a denomination
equal to the unredeemed portion of the principal of the Global Security so
surrendered.

the retirement of Securities of a series except as otherwise specified as
contemplated by Section 3.01 for Securities of such series.

     The minimum amount of any sinking fund payment provided for by the terms of
Securities of any series is herein referred to as a "mandatory sinking fund
payment," and any payment in excess of such minimum amount provided for by the
terms of Securities of any series is herein referred to as an "optional sinking
fund payment". If provided for by the terms of Securities of any series, the
cash amount of any sinking fund payment may be subject to reduction as provided
in Section 12.02. Each sinking fund payment shall be applied to the redemption
of Securities of any series as provided for by the terms of Securities of such
series.

     SECTION 12.02. SATISFACTION OF SINKING FUND PAYMENTS WITH SECURITIES.

     The Company (1) may deliver Outstanding Securities of like tenor of a
series (other than any previously called for redemption) and (2) may apply as a

portion thereof, if any, which is to be satisfied by delivering and crediting

time of delivery of such Officers' Certificate, will also deliver to the Trustee

expense of the Company in the manner provided in Section 11.04. Such notice
having been duly given, the redemption of such Securities shall be made upon the
terms and in the manner stated in Sections 11.06 and 11.07.

              ARTICLE THIRTEEN - DEFEASANCE AND COVENANT DEFEASANCE

     SECTION 13.01. APPLICABILITY OF ARTICLE; COMPANY'S OPTION TO EFFECT
DEFEASANCE OR COVENANT DEFEASANCE.

     If, pursuant to Section 3.01, provision is made for either or both of
(a) Defeasance of the Securities of or within a series under Section 13.02 or
(b) Covenant Defeasance of the Securities of or within a series under Section
13.03, then the provisions of such Section or Sections, as the case may be,
together with the other provisions of this Article (with such modifications
thereto as may be specified pursuant to Section 3.01 with respect to any
Securities), shall be applicable to such Securities and the Company may at
its option by Board Votes, at any time, with respect to such Securities and
any coupons appertaining thereto, elect to have Section 13.02 (if applicable)
or Section 13.03 (if applicable) be applied to such Outstanding Securities
upon compliance with the conditions set forth below in this Article.

     SECTION 13.02. DEFEASANCE AND DISCHARGE.

     Upon the Company's exercise of the above option applicable to this
Section with respect to any Securities of or within a series, the Company
shall be deemed to have been discharged from its obligations with respect to
such Outstanding Securities on the date the conditions set forth in Section
13.04 are satisfied (hereinafter, "Defeasance"). For this purpose, such
Defeasance means that the Company shall be deemed to have paid and discharged
the entire indebtedness represented by such Outstanding Securities, which
shall thereafter be deemed to be "Outstanding" only for the purposes of
Section 13.05 and the other Sections of this Indenture referred to in clauses
(A) and (B) below, and to have satisfied all of its other obligations under
such Securities and this Indenture insofar as such Securities are concerned
(and the Trustee, at the expense of the Company, shall execute proper
instruments acknowledging the same), except for the following which shall
survive until otherwise terminated or discharged hereunder: (A) the rights of
Holders of such Outstanding Securities to receive, solely from the trust fund
described in Section 13.04 and as more fully set forth in such Section,
payments in respect of the principal of (and premium or Make-Whole Amount, if
any) and interest, if any, on such Securities when such payments are due, (B)

3.05, 3.06, 10.02 and 10.03, and the Company's obligations under Section 6.06
hereof (C) the rights, powers, trusts, duties and immunities of the Trustee
hereunder and (D) this Article. Subject to compliance with this Article
Thirteen, the Company may exercise its option under this Section
notwithstanding the prior exercise of its option under Section 13.03 with
respect to such Securities.

     SECTION 13.03. COVENANT DEFEASANCE.

     Upon the Company's exercise of the above option applicable to this
Section with respect to any Securities of or within a series, the Company
shall be released from its obligations under Sections 10.04 to 10.09,
inclusive, and, if specified pursuant to Section 3.01, its obligations under
any other covenant contained herein or in any indenture supplemental hereto,
with respect to such Outstanding Securities on and after the date the
conditions set forth in Section 13.04 are

                                       62
<Page>

satisfied (hereinafter, "Covenant Defeasance"), and such Securities shall
thereafter be deemed to be not "Outstanding" for the purposes of any
direction, waiver, consent or declaration or Act of Holders (and the
consequences of any thereof) in connection with Sections 10.04 to 10.09,
inclusive, or such other covenant, but shall continue to be deemed
"Outstanding" for all other purposes hereunder. For this purpose, such
Covenant Defeasance means that, with respect to such Outstanding Securities,
the Company may omit to comply with and shall have no liability in respect of
any term, condition or limitation set forth in any such Section or such other
covenant, whether directly or indirectly, by reason of any reference
elsewhere herein to any such Section or such other covenant or by reason of
reference in any such Section or such other covenant to any other provision
herein or in any other document and such omission to comply shall not
constitute a default or an Event of Default under Section 5.01(4) or 5.01(8)
or otherwise, as the case may be, but, except as specified above, the
remainder of this Indenture and such Securities shall be unaffected thereby.

     SECTION 13.04. CONDITIONS TO DEFEASANCE OR COVENANT DEFEASANCE.

     The following shall be the conditions to application of Section 13.02 or
Section 13.03 to any Outstanding Securities of or within a series:

solely to, the benefit of the Holders of such Securities, (1) an amount in
such currency, currencies or currency unit in which such Securities are then
specified as payable at Stated Maturity, or (2) Government Obligations
applicable to such Securities (determined on the basis of the currency,

an amount, or (3) a combination thereof, in any case, in an amount,
sufficient, without consideration of any reinvestment of such principal and
interest, in the opinion of a nationally recognized firm of independent
public accountants expressed in a written certification thereof delivered to
the Trustee, to pay and discharge, and which shall be applied by the Trustee
(or other qualifying trustee) to pay and discharge, (i) the principal of (and
premium or Make-Whole Amount, if any) and interest, if any, on such
Outstanding Securities on the Stated Maturity of such principal or
installment of principal or interest and (ii) any mandatory sinking fund

ending on the 91st day after the date of such deposit (it being understood
that this condition shall not be deemed satisfied until the expiration of
such period).

shall have delivered to the Trustee an Opinion of Counsel stating that (i)
the Company has received from, or there has been published by, the Internal
Revenue Service a ruling, or (ii) since the date of execution 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 shall
confirm that, the Holders of such Outstanding Securities 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.

Defeasance had not occurred.

          (f) The Company shall have delivered to the Trustee an Officers'
Certificate and an Opinion of Counsel, each stating that all conditions
precedent to the Defeasance under Section 13.02 or the Covenant Defeasance
under Section 13.03 (as the case may be) have been complied with and an
Opinion of Counsel to the effect that either (i) as a result of a deposit
pursuant to subsection (a) above and the related exercise of the Company's
option under Section 13.02 or Section 13.03 (as the case may be),
registration is not required under the Investment Company Act of 1940, as
amended, by the Company, with respect to the trust funds representing such
deposit or by the Trustee for such trust funds or (ii) all necessary
registrations under said Act have been effected.

          (g) Notwithstanding any other provisions of this Section, such
Defeasance or Covenant Defeasance shall be effected in compliance with any
additional or substitute terms, conditions or limitations which may be imposed
on the Company in connection therewith pursuant to Section 3.01.

          (h) The payment of amounts payable to the Trustee pursuant to this
Indenture shall be paid or provided for to the reasonable satisfaction of the
Trustee.

     SECTION 13.05. DEPOSITED MONEY AND GOVERNMENT OBLIGATIONS TO BE HELD IN
TRUST; OTHER MISCELLANEOUS PROVISIONS.

     Subject to the provisions of the last paragraph of Section 10.03, all
money and Government Obligations (or other property as may be provided
pursuant to Section 3.01) (including the proceeds thereof) deposited with the
Trustee (or other qualifying trustee, collectively for purposes of this
Section 13.05, the "Trustee") pursuant to Section 13.04 in respect of any
Outstanding Securities of any series shall be held in trust and applied by
the Trustee, in accordance with the provisions of such Securities and this
Indenture, to the payment, either directly or through any Paying Agent
(including the Company acting as its own Paying Agent) as the Trustee may
determine, to the Holders of such Securities of all sums due and to become
due thereon in respect of principal (and premium or Make-Whole Amount, if
any) and interest, but such money need not be segregated from other funds
except to the extent required by law.

     Unless otherwise specified with respect to any Security pursuant to
Section 3.01, if, after a deposit referred to in Section 13.04(a) has been
made, (a) the Holder of a Security in respect of which such deposit was made
is entitled to, and does, elect pursuant to Section 3.01 or the terms of such
Security to receive payment in a currency or currency unit other than that in
which the deposit pursuant to Section 13.04(a)

                                       64
<Page>

has been made in respect of such Security, or (b) a Conversion Event occurs
in respect of the currency or currency unit in which the deposit pursuant to
Section 13.04(a) has been made, the indebtedness represented by such Security
shall be deemed to have been, and will be, fully discharged and satisfied
through the payment of the principal of (and premium or Make-Whole Amount, if
any), and interest, if any, on such Security as the same becomes due out of
the proceeds yielded by converting (from time to time as specified below in
the case of any such election) the amount or other property deposited in
respect of such Security into the currency or currency unit in which such
Security becomes payable as a result of such election or Conversion Event
based on the applicable market exchange rate for such currency or currency
unit in effect on the second Business Day prior to each payment date, except,
with respect to a Conversion Event, for such currency or currency unit in
effect (as nearly as feasible) at the time of the Conversion Event.

     The Company shall pay and indemnify the Trustee against any tax, fee or
other charge imposed on or assessed against the Government Obligations
deposited pursuant to Section 13.04 or the principal and interest received in
respect thereof other than any such tax, fee or other charge which by law is
for the account of the Holders of such Outstanding Securities.

     Anything in this Article to the contrary notwithstanding, subject to
Sections 6.06 and 6.07 the Trustee shall deliver or pay to the Company from
time to time upon Company Request any money or Government Obligations (or
other property and any proceeds therefrom) held by it as provided in Section
13.04 which, in the opinion of a nationally recognized firm of independent
public accountants expressed in a written certification thereof delivered to
the Trustee, are in excess of the amount thereof which would then be required
to be deposited to effect a Defeasance or Covenant Defeasance, as applicable,
in accordance with this Article.

Securities of such series and of the appointment of proxies and in regard to
the appointment and duties of inspectors of votes, the submission and
examination of proxies, certificates and other evidence of the right to vote,
and such other matters concerning the conduct of the meeting as it shall deem
appropriate. Except as otherwise permitted or required by any such
regulations, the holding of Securities shall be proved in the manner
specified in Section 1.04 and the appointment of any proxy shall be proved in
the manner specified in Section 1.04. Such regulations may provide that
written instruments appointing proxies, regular on their face, may be
presumed valid and genuine without the proof specified in Section 1.04 or
other proof.

temporary chairman of the meeting, unless the meeting shall have been called

delivered to the Company and another to the Trustee to be preserved by the
Trustee, the latter to have attached thereto the ballots voted at the

                   ARTICLE FIFTEEN - CONVERSION OF SECURITIES

     SECTION 15.01. APPLICABILITY OF ARTICLE; CONVERSION PRIVILEGE AND
CONVERSION PRICE.

     Securities of any series which are convertible shall be convertible in
accordance with their terms and (except as otherwise specified as
contemplated by Section 3.01 for Securities of any series) in accordance with
this Article Fifteen. Subject to and upon compliance with the provisions of
this Article Fifteen, at any time during the period specified in the
Securities, at the option of the Holder thereof, any Security or any portion
of the principal amount thereof which is $1,000 or an integral multiple of
$1,000 may be converted at the principal amount thereof, or of such portion
thereof, into fully paid and nonassessable shares (calculated as to each
conversion to the nearest 1/100 of a share) of Common Stock of the Company,
at the Conversion Price, determined as hereinafter provided, in effect at the
time of conversion. In case a Security or portion thereof is called for
redemption, such conversion right in respect of the Security or portion so
called shall expire at the close of business on the Business Day immediately
preceding the Redemption Date, unless the Company defaults in making the
payment due upon redemption, in which case such conversion right shall
terminate on the date such default is cured.

     The price at which shares of Common Stock shall be delivered upon
conversion (herein called the "Conversion Price") of Securities of any series
shall be specified in such Securities. The Conversion Price shall be adjusted
in certain instances as provided in Section 15.04.

     In case the Company shall, by dividend or otherwise, declare or make a
distribution on its Common Stock referred to in paragraph (4) of Section
15.04, the Holder of each Security, upon the conversion thereof pursuant to
this Article Fifteen subsequent to the close of business on the date fixed
for the determination of stockholders entitled to receive such distribution
and prior to the effectiveness of the Conversion Price adjustment in respect
of such distribution pursuant to paragraph (4) of Section 15.04, shall be
entitled to receive for each share of Common Stock into which such Security
is converted, the portion of the evidence of indebtedness, shares of Capital
Stock or assets so distributed applicable to one share of Common Stock;
provided, however, that, at the election of the Company (whose election shall
be evidenced by a Board Vote filed with the Trustee) with respect to all
Holders so converting, the Company may, in lieu of distributing to such
Holder any portion of such distribution not consisting of cash or securities
of the Company, pay such Holder an amount in cash equal to the fair market
value thereof (as determined in good faith by the Board of Directors, whose
determination shall be conclusive and described in a Board Vote filed with
the Trustee). If any conversion of a Security entitled to the benefits
described in the immediately preceding sentence occurs prior to the payment
date for a distribution to holders of Common Stock which the Holder of the
Security so converted is entitled to receive in accordance with the
immediately preceding sentence, the Company may elect (such election to be
evidenced by a Board Vote filed with the Trustee) to distribute to such
Holder a due bill for the evidences of indebtedness, shares of Capital Stock
or assets to which such Holder is so entitled, provided that such due bill
(i) meets any applicable requirements of the principal national securities
exchange or

                                       68
<Page>

other market on which the Common Stock is then traded, and (ii) requires payment
or delivery of such evidences of indebtedness or assets no later than the date
of payment or delivery thereof to holders of Common Stock receiving such
distribution.

     SECTION 15.02. EXERCISE OF CONVERSION PRIVILEGE.

     In order to exercise the conversion privilege, the Holder of any
Security to be converted shall surrender such Security, duly endorsed or
assigned to the Company or in blank, at any office or agency maintained by
the Company pursuant to Section 10.02, accompanied by written notice to the
Company at such office or agency that the Holder elects to convert such
Security or, if less than the entire principal amount thereof is to be
converted, the portion thereof to be converted and shall comply with any
additional requirements set forth in such Security. Securities surrendered
for conversion during the period from the close of business on any Regular
Record Date next preceding any Interest Payment Date to the opening of
business on such Interest Payment Date shall (except for Securities the
Maturity of which is prior to such Interest Payment Date) be accompanied by
payment in funds acceptable to the Company of an amount equal to the interest
payable on such Interest Payment Date on the principal amount of Securities
being surrendered for conversion and such interest shall be paid on such
Interest Payment Date as provided in Section 3.07. Except as provided in the
preceding sentence, no payment or adjustment shall be made upon any
conversion on account of any interest accrued on the Securities surrendered
for conversion or on account of any dividends on the Common Stock issued upon
conversion.

     The Company's delivery to the Holder of the fixed number of shares of the
Common Stock of the Company (and any cash in lieu of any fractional share of
Common Stock) into which the Security is convertible shall be deemed to satisfy
the Company's obligation to pay the principal amount of the Security and all
accrued interest and original issue discount that has not previously been paid.
The shares of Common Stock of the Company so delivered shall be treated as
issued first in payment of accrued interest and original issue discount and then
in payment of principal. Thus, accrued interest and original issue discount
shall be treated as paid, rather than canceled, extinguished or forfeited.

     Securities shall be deemed to have been converted immediately prior to the
close of business on the day of surrender of such Securities for conversion in
accordance with the foregoing provisions, and at such time the rights of the
Holders of such Securities as Holders shall cease, and the Person or Persons
entitled to receive the Common Stock issuable upon conversion shall be treated
for all purposes as the record holder or holders of such Common Stock at such
time. As promptly as practicable on or after the conversion date, the Company
shall issue and shall deliver at such office or agency a certificate or
certificates for the number of full shares of Common Stock issuable upon
conversion, together with payment in lieu of any fraction of a share, as
provided in Section 15.03.

     In the case of any Security which is converted in part only, as promptly as
practicable on or after the conversion date the Company shall execute and the
Trustee shall authenticate and make available for delivery to the Holder thereof
(or the Depositary in the case of a Global Security), at the expense of the
Company, a new Security or Securities, of authorized denominations in aggregate
principal amount equal to the unconverted portion of the principal amount of
such Security.

     SECTION 15.03. FRACTIONS OF SHARES.

     No fractional shares of Common Stock shall be issued upon conversion of
Securities. If more than one Security shall be surrendered for conversion at one
time by the same Holder, the number of full shares of Common Stock which shall
be issuable upon conversion thereof shall be computed on the basis of the
aggregate principal amount of the Securities (or specified portions thereof) so
surrendered. Instead of any fractional share of Common Stock which would
otherwise be issuable upon conversion of any

                                       69
<Page>

Security or Securities (or specified portions thereof), the Company shall pay a
cash adjustment (rounded to the nearest cent) in respect of such fraction in an
amount equal to the same fraction of the Closing Price per share of the Common
Stock on the day of conversion (or, if such day is not a Trading Day, on the
Trading Day immediately preceding such day).

     SECTION 15.04. ADJUSTMENT OF CONVERSION PRICE.

The Conversion Price shall be subject to adjustment from time to time as
follows:

          (a) If the Company pays or makes a dividend or other distribution (a)
on its Common Stock exclusively in Common Stock or (b) on any other class of
Capital Stock of the Company, which dividend or distribution includes Common
Stock of the Company, the Conversion Price in effect at the opening of business
on the day following the date fixed for the determination of stockholders
entitled to receive such dividend or other distribution (the "Dividend Record
Date") shall be reduced by multiplying such Conversion Price by a fraction of
which the numerator shall be the number of shares of Common Stock of the Company
outstanding at the close of business on the Dividend Record Date and the
denominator shall be the sum of such number of shares and the total number of
shares constituting such dividend or other distribution. Such reduction shall
become effective immediately after the opening of business on the day following
the date fixed for such determination. For the purposes of this paragraph (a),
the number of shares of Common Stock of the Company at any time outstanding
shall not include shares held in the treasury of the Company, but shall include
shares issuable in respect of scrip certificates issued in lieu of fractions of
shares of Common Stock. The Company shall not pay any dividend or make any
distribution on shares of Common Stock held in the treasury of the Company.

          (b) Subject to paragraph (f) of this Section, if the Company pays
or makes a dividend or other distribution on its Common Stock consisting
exclusively of Short Term Rights (as defined below), or otherwise issues
Short Term Rights to all holders of its Common Stock, the Conversion Price in
effect at the opening of business on the day following the record date for
the determination of holders of Common Stock entitled to receive such Short
Term Rights (the "Rights Record Date") shall be reduced by multiplying such
Conversion Price by a fraction of which the numerator shall be the number of
shares of Common Stock of the Company outstanding at the close of business on
the Rights Record Date plus the number of shares of Common Stock of the
Company which the aggregate of the offering price of the total number of
shares of Common Stock so offered for subscription or purchase would purchase
at such current market price and the denominator shall be the number of
shares of Common Stock of the Company outstanding at the close of business on
the Rights Record Date plus the number of shares of Common Stock so offered
for subscription or purchase. Such reduction shall become effective
immediately after the opening of business on the day following the Rights
Record Date. For the purposes of this paragraph (b), the number of shares of
Common Stock of the Company at any time outstanding shall not include shares
held in the treasury of the Company, but shall include shares issuable in
respect of scrip certificates issued in lieu of fractions of shares of Common
Stock of the Company. The Company shall not issue any rights, options or
warrants in respect of shares of its Common Stock held in the treasury of the
Company. When used in this Section 15.04, the term "Short Term Rights" shall
mean rights, warrants or options entitling the holders thereof (for a period
commencing no earlier than the Rights Record Date and expiring not more than
45 days after the Rights Record Date) to subscribe for or purchase shares of
Common Stock of the Company at a price per share less than the current market
price per share (determined as provided in paragraph (g) of this Section
15.04) of the Common Stock of the Company on the Rights Record Date.

          (c) In case outstanding shares of Common Stock of the Company shall be
subdivided into a greater number of shares of Common Stock, the Conversion Price
in effect at the opening of business on the day following the day upon which
such subdivision becomes effective shall be

                                       70
<Page>

proportionately reduced, and, conversely, in case outstanding shares of Common
Stock of the Company shall be combined into a smaller number of shares of Common
Stock, the Conversion Price in effect at the opening of business on the day
following the day upon which such combination becomes effective shall be
proportionately increased, such reduction or increase, as the case may be, to
become effective immediately after the opening of business on the day following
the day upon which such subdivision or combination becomes effective.

          (d) Subject to the last sentence of this paragraph (d) of this
Section, if the Company, by dividend or otherwise, (a) distributes to all
holders of its Common Stock evidences of its indebtedness, shares of any
class of Capital Stock of the Company or other assets (other than cash
dividends out of current or retained earnings), or (b) distributes to
substantially all holders of Common Stock rights or warrants to subscribe for
securities (other than Short Term Rights to which paragraph (b) of this
Section 15.04 applies), the Conversion Price shall be reduced by multiplying
such Conversion Price by a fraction of which the numerator shall be the
current market price per share (determined as provided in paragraph (g) of
this Section 15.04) of the Common Stock of the Company on the Reference Date
(as defined below) less the fair market value (as determined in good faith by
the Board of Directors, whose determination shall be conclusive and described
in a Board Vote filed with the Trustee), on the Reference Date, of the
portion of the evidences of indebtedness and other assets so distributed or
of such subscription rights or warrants applicable to one share of Common
Stock (collectively, the "Market Value of the Distribution") and the
denominator shall be such current market price per share of the Common Stock
of the Company. Such reduction shall become effective immediately prior to
the opening of business on the day (the "Reference Date") following the later
of (a) the date fixed for the payment of such distribution and (b) the date
20 days after notice relating to such distribution is required to be given
pursuant to Section 15.06(a). If the Board of Directors determines the fair
market value of any distribution for purposes of this paragraph (d) by
reference to the actual or when issued trading market for any securities
comprising such distribution, it must in doing so consider the prices in such
market over the same period used in computing the current market price per
share pursuant to paragraph (g) of this Section 15.04. In the event that,
with respect to any distribution to which this paragraph (d) of Section 15.04
would otherwise apply, the Market Value of the Distribution is greater than
the current market price per share of the Common Stock (such distribution
being referred to herein as an "Unadjusted Distribution"), then the
adjustment provided by this paragraph (d) shall not be made and in lieu
thereof the provisions of Section 15.11 shall apply with respect to such
Unadjusted Distribution.

          (e) The Company may, but shall not be required to, make such
reductions in the Conversion Price, in addition to those required by
paragraphs (a), (b), (c), and (d) of this Section 15.04, as it considers to
be advisable in order that any event treated for federal income tax purposes
as a dividend of stock or stock rights shall not be taxable to the
recipients. In addition, the Company, from time to time, may decrease the
Conversion Price by any amount and for any reason, temporarily or otherwise,
including situations where the Board of Directors determines such decrease to
be fair and appropriate with respect to transactions in which holders of
Common Stock have the right to participate.

          (f) Rights or warrants issued or distributed by the Company to all
holders of its Common Stock entitling the holders thereof to subscribe for or
purchase shares of Common Stock or Preferred Stock, which rights or warrants
(i) are deemed to be transferred with such shares of Common Stock, (ii) are
not exercisable and (iii) are also issued or distributed in respect of future
issuances of Common Stock, in each case in clauses (i) through (iii) until
the occurrence of a specified event or events ("Trigger Events"), shall for
purposes of this Section 15.04 not be deemed issued or distributed until the
occurrence of the earliest Trigger Event. Each share of Common Stock issued
upon conversion of Securities pursuant to this Article Fifteen shall be
entitled to receive the appropriate number of Common Stock purchase rights
(the "Rights"), if any, and the certificates representing the Common Stock
issued upon conversion shall bear such legends, if any. Notwithstanding
anything to the contrary in this Article

                                       71
<Page>

Fifteen, there shall not be any adjustment to the Conversion Price as a result
of (i) the distribution of separate certificates representing the Rights; (ii)
the occurrence of certain events entitling holders of Rights to receive, upon
exercise thereof, Common Stock or other securities of the Company or other
securities of another corporation; or (iii) the exercise of such Rights. No
adjustment in the Conversion Price need be made for rights to purchase or the
sale of Common Stock pursuant to a Company plan providing for reinvestment of
dividends or interest.

          (g) For the purpose of any computation under paragraph (b), (d) or
(e) of this Section 15.04, the "current market price" per share of Common
Stock of the Company on any date shall be deemed to be the average of the
daily Closing Prices for the 15 consecutive Trading Days selected by the
Company commencing not more than 30 Trading Days before, and ending not later
than, the date in question.

          (h) No adjustment in the Conversion Price shall be required unless
such adjustment would require an increase or decrease of at least 1% in the
Conversion Price; provided, however, that any adjustments which by reason of
this paragraph (h) are not required to be made shall be carried forward and
taken into account in any subsequent adjustment. All calculations under this
Article Fifteen shall be made to the nearest cent or to the nearest
one-hundredth of a share of Common Stock, as the case may be.

          (i) Anything herein to the contrary notwithstanding, in the event the
Company shall declare any dividend or distribution requiring an adjustment in
the Conversion Price hereunder and shall, thereafter and before the payment of
such dividend or distribution to stockholders, legally abandon its plan to pay
such dividend or distribution, the Conversion Price then in effect hereunder, if
changed to reflect such dividend or distribution, shall upon the legal
abandonment of such plan be changed to the Conversion Price which would have
been in effect at the time of such abandonment (after giving effect to all other
adjustments not so legally abandoned pursuant to the provisions of this Article
Fifteen) had such dividend or distribution never been declared.

          (j) Notwithstanding any other provision of this Section 15.04, no
adjustment to the Conversion Price shall reduce the Conversion Price below
the then par value per share of the Common Stock of the Company, and any such
purported adjustment shall instead reduce the Conversion Price to such par
value. Notwithstanding the foregoing sentence, the Company hereby covenants
that it will from time to time take all such action as may be required to
assure that the par value per share of the Common Stock is at all times equal
to or less than the Conversion Price.

          (k) In the event that this Article Fifteen requires adjustments to
the Conversion Price under more than one of paragraphs (a), (b), (c) or (d)
of this Section 15.04, and the record or effective dates for the transaction
giving rise to such adjustments shall occur on the same date, then such
adjustments shall be made by applying (to the extent they are applicable),
first, the provisions of paragraph (c) of this Section 15.04, second, the
provisions of paragraph (a) of this Section 15.04, third, the provisions of
paragraph (d) of this Section 15.04 and, fourth, the provisions of paragraph
(b) of this Section 15.04. Anything herein to the contrary notwithstanding,
no single event shall require or result in duplicative adjustments in the
Conversion Price pursuant to this Section 15.04. After an adjustment to the
Conversion Price under this Article Fifteen, any subsequent event requiring
an adjustment under this Article Fifteen shall cause an adjustment to the
Conversion Price as so adjusted. If, after an adjustment, a Holder of a
Security upon conversion of such Security receives shares of two or more
classes of Capital Stock of the Company, the Conversion Price shall
thereafter be subject to adjustment upon the occurrence of an action taken
with respect to any such class of Capital Stock as is contemplated by this
Article Fifteen with respect to the Common Stock in this Article Fifteen.

     SECTION 15.05. NOTICE OF ADJUSTMENTS OF CONVERSION PRICE.

Whenever the Conversion Price is adjusted as herein provided:

          (a) the Company shall compute the adjusted Conversion Price in
accordance with Section 15.04 or Section 15.11 and shall prepare an Officer's
Certificate setting forth the adjusted Conversion Price and showing in
reasonable detail the facts upon which such adjustment is based, and such
certificate shall forthwith be filed (with a copy to the Trustee) at each
office or agency maintained for the purpose of conversion of any Securities
pursuant to Section 10.02; and

          (b) a notice stating that the Conversion Price has been adjusted and
setting forth the adjusted Conversion Price shall forthwith be required, and as
soon as practicable after it is required, such notice shall be mailed by the
Company to all Holders at their last addresses as they shall appear in the
Security Register.

     SECTION 15.06. NOTICE OF CERTAIN CORPORATE ACTION.

     In case:

          (a) the Company shall take any action that would require a
Conversion Price adjustment pursuant to Section 15.04 or Section 15.11; or

          (b) there shall occur any reclassification of the Common Stock of the
Company (other than a subdivision or combination of its outstanding shares of
Common Stock), or any consolidation or merger to which the Company is a party,
or the sale, transfer or lease of all or substantially all of the assets of the
Company and for which approval of any stockholders of the Company is required;
or

          (c) there shall occur the voluntary or involuntary dissolution,
liquidation or winding up of the Company, then the Company shall cause to be
filed at each office or agency maintained for the purpose of conversion of
Securities pursuant to Section 10.02, and shall cause to be mailed to all
Holders at their last addresses as they shall appear in the Security
Register, at least 10 days prior to the applicable record, effective or
expiration date hereinafter specified, a notice stating (x) the date on which
a record is to be taken for the purpose of any dividend, distribution or
granting of rights, warrants or options, or, if a record is not to be taken,
the date as of which the holders of Common Stock of record to be entitled to
such dividend, distribution, rights, options or warrants are to be
determined, or (y) the date on which such reclassification, consolidation,
merger, sale, transfer, dissolution, liquidation or winding up is expected to
become effective, and, if applicable, the date as of which it is expected
that holders of Common Stock of record shall be entitled to exchange their
shares of Common Stock for securities, cash or other property deliverable
upon such reclassification, consolidation, merger, sale, transfer,
dissolution, liquidation or winding up.

     SECTION 15.07. COMPANY TO RESERVE COMMON STOCK.

The Company shall at all times reserve and keep available, free from preemptive
rights, out of its authorized but unissued Common Stock, for the purpose of
effecting the conversion of Securities, a number of shares of Common Stock for
the conversion of all outstanding Securities of any series which is convertible
into Common Stock.

                                       73
<Page>

     SECTION 15.08. TAXES ON CONVERSION.

     The Company will pay any and all taxes that may be payable in respect of
the issue or delivery of shares of Common Stock on conversion of Securities
pursuant hereto. The Company shall not, however, be required to pay any tax
which may be payable in respect of any transfer involved in the issue and
delivery of shares of Common Stock in a name other than that of the Holder of
the Security or Securities to be converted, and no such issue or delivery shall
be made unless and until the Person requesting such issue has paid to the
Company the amount of any such tax, or has established to the satisfaction of
the Company that such tax has been paid.

     SECTION 15.09. COVENANTS AS TO COMMON STOCK.

     The Company covenants that all shares of Common Stock which may be
issued upon conversion of Securities will upon issue be duly and validly
issued, fully paid and nonassessable, free of preemptive or any similar
rights, and, except as provided in Section 15.08, the Company will pay all
taxes, liens and charges with respect to the issue thereof.

     The Company will endeavor promptly to comply with all Federal and state
securities laws regulating the offer and delivery of shares of Common Stock upon
conversion of Securities, if any, and will list or cause to have quoted such
shares of Common Stock on each national securities exchange or in the
over-the-counter market or such other market on which the Common Stock is then
listed or quoted.

     SECTION 15.10. CANCELLATION OF CONVERTED SECURITIES.

     All Securities delivered for conversion shall be delivered to the
Trustee to be cancelled by or at the direction of the Trustee, which shall
dispose of the same as provided in Section 3.09.

     SECTION 15.11. PROVISIONS IN CASE OF CONSOLIDATION, MERGER OR SALE OF
ASSETS; SPECIAL DISTRIBUTIONS.

     If any of the following shall occur, namely: (i) any reclassification or
change of outstanding shares of Common Stock issuable upon conversion of
Securities (other than a change in par value, or from par value to no par
value, or from no par value to par value, or as a result of a subdivision or
combination), (ii) any consolidation or merger to which the Company is a
party other than a merger in which the Company is the continuing corporation
and which does not result in any reclassification of, or change (other than a
change in name, or par value, or from par value to no par value, or from no
par value to par value or as a result of a subdivision or combination) in,
outstanding shares of Common Stock or (iii) any sale or conveyance of all or
substantially all of the property or business of the Company as an entirety,
then the Person formed by such consolidation or resulting from such merger or
which acquires such properties or assets, as the case may be, shall as a
condition precedent to such transaction execute and deliver to the Trustee a
supplemental indenture providing that the Holder of each Security then
outstanding shall have the right thereafter, during the period such Security
shall be convertible as specified in Section 15.01, to convert such Security
only into the kind and amount of securities, cash and other property
receivable, if any, upon such consolidation, merger, sale, transfer or lease
by a holder of the number of shares of Common Stock of the Company into which
such Security might have been converted immediately prior to such
consolidation, merger, sale, transfer or lease; provided that the kind and
amount of securities, cash and other property so receivable shall be
determined on the basis of the following assumptions. The holder of Common
Stock referred to in the foregoing sentence:

          (a) is not (a) a Person with which the Company consolidated, (b) a
Person into which the Company merged or which merged into the Company, or (c) a
Person to which such sale, transfer or

                                       74
<Page>

lease was made (any Person described in the foregoing clauses (a), (b), or (c),
hereinafter referred to as a "Constituent Person"), or (d) an Affiliate of a
Constituent Person; and

          (b) failed to exercise his rights of election, if any, as to the
kind or amount of securities, cash and other property receivable upon such
consolidation, merger, sale, transfer or lease (provided that if the kind or
amount of securities, cash and other property receivable upon such
consolidation, merger, sale transfer or lease is not the same for each share
of Common Stock of the Company in respect of which such rights of election
shall not have been exercised, then for the purpose of this Section 15.11 the
kind and amount of securities, cash and other property receivable upon such
consolidation, merger, sale, transfer or lease shall be deemed to be the kind
and amount so receivable per share by a plurality of such shares of Common
Stock).

     Such supplemental indenture shall provide for adjustments which, for events
subsequent to the effective date of such supplemental indenture, shall be as
nearly equivalent as may be practicable to the adjustments provided for in this
Article Fifteen. If, in the case of any such consolidation, merger, sale
transfer or lease the stock or other securities and property (including cash)
receivable thereupon by a holder of Common Stock includes shares of stock or
other securities and property of a corporation other than the successor or
purchasing corporation, as the case may be, in such consolidation, merger, sale,
transfer or lease then such supplemental indenture shall also be executed by
such other corporation and shall contain such additional provisions to protect
the interests of the Holders of the Securities as the Board of Directors of the
Company shall reasonably consider necessary by reason of the foregoing. The
above provisions of this Section 15.11 shall similarly apply to successive
consolidations, mergers, sales, transfers or leases.

     In the event the Company shall execute a supplemental indenture pursuant
to this Section 15.11, the Company shall promptly file with the Trustee an
Officers' Certificate briefly stating the reasons therefor, the kind or
amount of shares of stock or securities or property (including cash)
receivable by Holders of the Securities upon the conversion of their
Securities after any such reclassification, change, consolidation, merger,
sale, transfer or lease and any adjustment to be made with respect thereto.

     If the Company makes a distribution to all holders of its Common Stock
that constitutes an Unadjusted Distribution pursuant to the last sentence of
paragraph (4) of Section 15.04, then, from and after the record date for
determining the holders of Common Stock entitled to receive such distribution
(the "Distribution Record Date"), a Holder of a Security who converts such
Security in accordance with the provisions of this Indenture shall, upon
conversion, be entitled to receive, in addition to the shares of Common Stock
into which the Security is convertible, the kind and amount of evidences of
indebtedness, shares of Capital Stock, or other assets or subscription rights
or warrants, as the case may be, comprising the distribution that such Holder
would have received if such Holder had converted the Security immediately
prior to the Distribution Record Date.

     SECTION 15.12. TRUSTEE ADJUSTMENT DISCLAIMER; COMPANY DETERMINATION FINAL.

     The Trustee has no duty to determine when an adjustment under this
Article Fifteen should be made, how it should be made or what it should be.
The Trustee has no duty to determine whether a supplemental indenture under
Section 15.11 need be entered into or whether any provisions of any
supplemental indenture are correct. The Trustee shall not be accountable for
and makes no representation as to the validity or value of any securities or
assets issued upon conversion of Securities. The Trustee shall not be
responsible for the Company's failure to comply with this Article Fifteen.
Any determination that the Company or the Board of Directors must make
pursuant to this Article Fifteen is conclusive, absent manifest error.

                                       75
<Page>

     SECTION 15.13. WHEN NO ADJUSTMENT REQUIRED.

     Except as expressly set forth in Section 15.04, no adjustment in the
Conversion Price shall be made because the Company issues, in exchange for
cash, property or services, shares of its Common Stock, or any securities
convertible into or exchangeable for shares of its Common Stock, or
securities (including warrants, rights and options) carrying the right to
subscribe for or purchase shares of its Common Stock or such convertible or
exchangeable securities.

          (a) Notwithstanding anything herein to the contrary, no adjustment
in the Conversion Price shall be made pursuant to Section 15.04 in respect of
any dividend or distribution if the Holders may participate therein (on a
basis to be determined in good faith by the Board of Directors) and receive
the same consideration they would have received if they had converted the
Securities immediately prior to the record date with respect to such dividend
or distribution.

     SECTION 15.14. EQUIVALENT ADJUSTMENTS.

     In the event that, as a result of an adjustment made pursuant to Section
15.04 above, the holder of any Security thereafter surrendered for conversion
shall become entitled to receive any shares of Capital Stock of the Company
other than shares of its Common Stock, thereafter the Conversion Price of
such other shares so receivable upon conversion of any Securities shall be
subject to adjustment from time to time in a manner and on terms as nearly
equivalent as practicable to the provisions with respect to Common Stock
contained in this Article Fifteen.

                                       76
