of any date, (A) the principal amount of an Original Issue Discount Security which shall be deemed
to be Outstanding shall be the amount of the principal thereof which would be due and payable as of
such date upon acceleration of the Maturity thereof to such date pursuant to Section 5.02, (B) if,
as of such date, the principal amount payable at the Stated Maturity of a Security is not
determinable, the principal amount of such Security which

contemplated by Section 3.01, (C) the principal amount of a Security denominated in one or more
foreign currencies or currency units which shall be deemed to be Outstanding shall be the U.S.
dollar equivalent, determined as of such date in the manner provided as contemplated by Section
3.01, of the principal amount of such Security (or, in the case of a Security described in Clause

direction, notice, consent, waiver or other action, only Securities which a Responsible Officer of
the Trustee actually knows to be so owned shall be so disregarded. Securities so owned which have
been pledged in good faith may be regarded as Outstanding if the pledgee establishes to the

     Where any Person is required to make, give or execute two or more applications, requests,
consents, certificates, statements, opinions or other instruments under this Indenture, they may,
but need not, be consolidated and form one instrument.

SECTION 1.04 Acts of Holders; Record Dates.

     (a) Any request, demand, authorization, direction, notice, consent, waiver or other action
provided or permitted by this Indenture to be given, made or taken by Holders may be embodied in
and evidenced by one or more instruments of substantially similar tenor signed by such Holders in
person or by agent duly appointed in writing; and, except as herein otherwise expressly provided,
such action shall become effective when such instrument or instruments are delivered to a
Responsible Officer of the Trustee and, where it is hereby expressly required, to the Company.
Such instrument or instruments (and the action embodied therein and evidenced thereby) are herein
sometimes referred to as the “Act” of the Holders signing such instrument or instruments. Proof of
execution of any such instrument or of a writing appointing any such agent shall be sufficient for
any purpose of this Indenture and (subject to Section 6.01) conclusive in favor of the Trustee and
the Company, if made in the manner provided in this Section.

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

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

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

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

8

 

previously been set pursuant to this paragraph (whereupon the record date previously set shall
automatically and with no action by any Person be cancelled and of no effect), and nothing in this
paragraph shall be construed to render ineffective any action taken by Holders of the requisite
principal amount of Outstanding Securities of the relevant series on the date such action is taken.
Promptly after any record date is set pursuant to this paragraph, the Company, at its own expense,
shall cause notice of such record date, the proposed action by Holders and the applicable
Expiration Date to be given to the Trustee in writing and to each Holder of Securities of the
relevant series in the manner set forth in Section 1.06.

     (f) The Trustee may set any day as a record date for the purpose of determining the Holders of
Outstanding Securities of any series entitled to join in the giving or making of (i) any Notice of
Default, (ii) any declaration of acceleration referred to in Section 5.02, (iii) any request to
institute proceedings referred to in Section 5.07(2) or (iv) any direction referred to in Section
3.05(2) or Section 5.12, in each case with respect to Securities of such series. If any record
date is set pursuant to this paragraph, the Holders of Outstanding Securities of such series on
such record date, and no other Holders, shall be entitled to join in such notice, declaration,
request or direction, whether or not such Holders remain Holders after such record date; provided
that no such action shall be effective hereunder unless taken on or prior to the applicable
Expiration Date by Holders of the requisite principal amount of Outstanding Securities of such
series on such record date. Nothing in this paragraph shall be construed to prevent the Trustee
from setting a new record date for any action for which a record date has previously been set
pursuant to this paragraph (whereupon the record date previously set shall automatically and with
no action by any Person be cancelled and of no effect), and nothing in this paragraph shall be
construed to render ineffective any action taken by Holders of the requisite principal amount of
Outstanding Securities of the relevant series on the date such action is taken. Promptly after any
record date is set pursuant to this paragraph, the Trustee, at the Company’s expense, shall cause
notice of such record date, the proposed action by Holders and the applicable Expiration Date to be
given to the Company in writing and to each Holder of Securities of the relevant series in the
manner set forth in Section 1.06.

     (g) With respect to any record date set pursuant to this Section, the party hereto which sets
such record dates may designate any day as the “Expiration Date” and from time to time may change
the Expiration Date to any earlier or later day; provided that no such change shall be effective
unless notice of the proposed new Expiration Date is given to the other party hereto in writing,
and to each Holder of Securities of the relevant series in the manner set forth in Section 1.06, on
or prior to the existing Expiration Date. If an Expiration Date is not designated with respect to
any record date set pursuant to this Section, the party hereto which set such record date shall be
deemed to have initially designated the 90th day after such record date as the Expiration Date with
respect thereto, subject to its right to change the Expiration Date as provided in this paragraph.
Notwithstanding the foregoing, no Expiration Date shall be later than the 90th day after the
applicable record date.

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

SECTION 1.05 Notices, Etc., to Trustee and Company.

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

          (1) the Trustee by any Holder or by the Company shall be sufficient for every purpose
hereunder if made, given, furnished or filed in writing to or with a Responsible Officer of the
Trustee at its Corporate Trust Office.

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

SECTION 1.06 Notice to Holders; Waiver.

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

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

SECTION 1.07 Conflict with Trust Indenture Act.

     If any provision hereof limits, qualifies or conflicts with a provision of the Trust Indenture
Act which is required under such Act to be a part of and govern this Indenture, the latter
provision shall control. If any provision of this Indenture modifies or excludes any provision of
the Trust Indenture Act which may be so modified or excluded, the latter provision shall be deemed
to apply to this Indenture as so modified or to be excluded, as the case may be.

SECTION 1.08 Effect of Headings and Table of Contents.

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

SECTION 1.09 Successors and Assigns.

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

SECTION 1.10 Separability Clause.

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

SECTION 1.11 Benefits of Indenture.

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

SECTION 1.12 Governing Law.

     This Indenture and the Securities shall be governed by and construed in accordance with the
law of the State of New York. This Indenture is subject to the provisions of the Trust Indenture
Act that are required or deemed to be part of this Indenture and shall, to the extent applicable,
be governed by such provision.

     EACH OF THE COMPANY AND THE TRUSTEE, AND EACH HOLDER OF A SECURITY BY ITS ACCEPTANCE THEREOF,
HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT IT
MAY HAVE TO TRIAL BY JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING
TO THIS INDENTURE, THE SECURITIES OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY.

SECTION 1.13 Legal Holidays.

     In any case where any Interest Payment Date, Redemption Date or Stated Maturity of any
Security shall not be a Business Day at any Place of Payment, then (notwithstanding any other
provision of this Indenture or of the Securities (other than a provision of any Security which
specifically states that such provision shall apply in lieu of this Section)) payment of interest
or principal (and premium, if any) need not be made at such Place of Payment on such date, but may
be made on the next succeeding Business Day at such Place of Payment with the same force and effect
as if made on the Interest Payment Date or Redemption Date, or at the Stated Maturity, provided
that no interest shall accrue with respect to such payment for the period from and after such
Interest Payment Date, Redemption Date or Stated Maturity, as the case may be.

SECTION 2.06 Securities Issuable in the Form of a Global Security.

     (a) If the Company shall establish pursuant to Section 3.01 that the Securities of a
particular series are to be issued in whole or in part in the form of one or more Global
Securities, then the Company shall execute and the Trustee shall, in accordance with Section 3.03
and the Company Order delivered to the Trustee thereunder, authenticate and deliver, such Global
Security or Securities, which (i) shall represent, and shall be denominated in an amount equal to
the aggregate principal amount of, the Outstanding Securities of such series to be represented by
such Global Security or Securities, (ii) shall be registered in the name of the Depositary for such
Global Security or Securities or its nominee, (iii) shall be delivered by the Trustee to the
Depositary or pursuant to the Depositary’s instruction and (iv) shall bear a legend substantially
to the following effect: “Unless and until it is exchanged in whole or in part for the individual
Securities represented hereby, this Global Security may not be transferred except as a whole by the
Depositary to a nominee of the Depositary or by a nominee of the Depositary to the Depositary or
another nominee of the Depositary or by the Depositary or any such nominee to a successor
Depositary or a nominee of such success Depositary.”

     (b) Notwithstanding any other provision of this Section 2.06 or of Section 3.05, unless the
terms of a Global Security expressly permit such Global Security to be exchanged in whole or in
part for individual Securities, a Global Security may be transferred, in whole but not in part and
in the manner provided in Section 3.05, only to the Depositary or another nominee of the Depositary
for such Global Security, or to a successor Depositary for such Global Security selected or
approved by the Company or to a nominee of such successor Depositary. Except as provided below,
owners of beneficial interests in a Global Security shall not be entitled to receive physical
delivery of the Securities represented by such Global Security and will not be considered the
Holders thereof for any purpose under this Indenture.

     (c) (i) If at any time the Depositary for a Global Security notifies the Company that it is
unwilling or unable to continue as Depositary for such Global Security or if at any time the
Depositary for the Securities for such series shall no longer be eligible or in good standing under
the Securities Exchange Act of 1934, as amended, or other applicable statute or regulation,

18

 

the Company shall appoint a successor Depositary with respect to such Global Security. If a
successor Depositary for such Global Security is not appointed by the Company within 90 days after
the Company receives such notice or becomes aware of such ineligibility, the Company’s election
pursuant to Section 3.01(16) shall no longer be effective with respect to such Global Security and
the Company will execute, and the Trustee, upon receipt of a Company Order for the authentication
and delivery of individual Securities of such series in exchange for such Global Security, will
authenticate and deliver individual Securities of such series of like tenor and terms in definitive
form in an aggregate principal amount equal to the principal amount of the Global Security in
exchange for such Global Security.

          (ii) The Company may at any time and in its sole discretion determine that the Securities of
any series issued or issuable in the form of one or more Global Securities shall no longer be
represented by such Global Security or Securities. In such event the Company will execute, and the
Trustee, upon receipt of a Company Order for the authentication and delivery of individual
Securities of such series in exchange in whole or in part for such Global Security, will
authenticate and deliver individual Securities of such series of like tenor and terms in definitive
form in an aggregate principal amount equal to the principal amount of such Global Security or
Securities representing such series in exchange for such Global Security or Securities.

          (iii) A Global Security will also be exchangeable if there shall have occurred or be
continuing a default or an event which, with the giving of notice or lapse of time or both, would
constitute a default with respect to the Securities of such series represented by such Global
Security. In such event the Company will execute, and the Trustee, upon receipt of a Company Order
for the authentication and delivery of individual Securities of such series in exchange in whole or
in part for such Global Security, will authenticate and deliver individual Securities of such
series of like tenor and terms in definitive form in an aggregate principal amount equal to the
principal amount of such Global Security or Securities representing such series in exchange for
such Global Security or Securities.

          (iv) If specified by the Company pursuant to Section 3.01 with respect to Securities issued or
issuable in the form of a Global Security, the Depositary for such Global Security may surrender
such Global Security in exchange in whole or in part for individual Securities of such series of
like tenor and terms in definitive form on such terms as are acceptable to the Company and such
Depositary. Thereupon the Company shall execute, and the Trustee shall authenticate and deliver,
without service charge, (1) to each Person specified by such Depositary a new Security or
Securities of the same series of like tenor and terms and of any authorized denominations as
requested by such Person or the Depositary in aggregate principal amount equal to and in exchange
for such Person’s beneficial interest in the Global Security; and (2) to such Depositary a new
Global Security of like tenor and terms and in a denomination equal to the difference, if any,
between the principal amount of the surrendered Global Security and the aggregate principal amount
of Securities delivered to Holders thereof.

          (v) In any exchange provided for in any of the preceding four paragraphs, the Company will
execute and the Trustee will authenticate and deliver individual fully registered Securities in
authorized denominations. Upon the exchange of a Global Security for individual Securities, such
Global Security shall be cancelled by the Trustee. Securities issued in exchange for a Global
Security pursuant to this Section 2.06 shall be registered in such names and in such authorized
denominations as the Depositary for such Global Security, pursuant to the instructions

19

 

from its direct or indirect participants or otherwise, shall instruct the Trustee in writing.
The Trustee shall deliver such Securities to the Persons in whose names such Securities are so
registered.

          (vi) Members in and participants of the Depositary shall have no rights under the Indenture
with respect to any Global Security held on their behalf by a Depositary, 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 for all purposes whatsoever. Notwithstanding the foregoing, 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 its members and participants, the operation of customary
practices governing the exercise of the rights of a Holder of any Security of the series
represented by such Global Security, including, without limitation, the granting of proxies or
other authorization of participants to give or take any request, demand, authorization, direction,
notice, consent, waiver or other action which a Holder is entitled to give or take under the
Indenture.

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

for issuances of additional securities of such series.

     Unless otherwise specifically provided with respect to the Securities of a series, at the
option of the Company, interest on the Securities of any series that bears interest may be paid by
mailing a check to the address of the person entitled thereto as such address shall appear in the
Security Register.

     If any of the terms of the series are established by action taken pursuant to a Board
Resolution, a copy of an appropriate record of such action shall be certified by the Secretary or

22

 

Securities of such series shall be issuable in denominations of $1,000 and any integral
multiple thereof.

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, attested by its Secretary
or one of its Assistant Secretaries. The signature of any of these officers on the Securities may
be manual or facsimile.

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

     At any time and from time to time after the execution and delivery of this Indenture, the
Company may deliver Securities of any series executed by the Company to the Trustee for
authentication, together with a Company Order for the authentication and delivery of such
Securities, 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 Resolutions 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,

          (1) if the form of such Securities has been established by or pursuant to Board Resolution as
permitted by Section 2.01, that such form has been established in conformity with the provisions of
this Indenture;

          (2) if the terms of such Securities have been established by or pursuant to Board Resolution
as permitted by Section 3.01, that such terms have been established in conformity with the
provisions of this Indenture;

          (3) 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 bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and
similar laws of general applicability relating to or affecting creditors’ rights and to general
equity principles;

          (4) that all laws and requirements in respect of the execution and delivery by the Company of
such Securities have been complied with; and

          (5) that all conditions precedent under the Indenture relating to the authentication and
delivery of such securities have been complied with.

     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

23

 

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.

     Notwithstanding the provisions of Section 3.01 and of the preceding paragraph, if all
Securities of a series are not to be originally issued at one time, it shall not be necessary to
deliver the Officers’ Certificate otherwise required pursuant to Section 3.01 or the Company Order
and Opinion of Counsel otherwise required pursuant to such preceding paragraph at or prior to the
authentication of each Security of such series if such documents are delivered at or prior to the
authentication upon original issuance of the first Security of such series to be issued.

     Each Security shall be dated the date of its authentication.

     No Security shall be entitled to any benefit under this Indenture or be valid or obligatory
for any purpose unless there appears on such Security a certificate of authentication substantially
in the form provided for herein executed by the Trustee by 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. Notwithstanding the foregoing, if any Security shall
have been authenticated and delivered hereunder but never issued and sold by the Company, and the
Company shall deliver such Security to the Trustee for cancellation as provided in Section 3.09,
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.

     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 and with such appropriate insertions, omissions, substitutions and other variations as the
officers executing such Securities may determine, as evidenced by their execution of such
Securities.

     If temporary Securities of any series are issued, the Company will cause definitive Securities
of 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 such series upon surrender of the temporary Securities of such series at
the office or agency of the Company in a Place of Payment for that series, without charge to the
Holder. Upon surrender for cancellation of any one or more temporary Securities of any series, the
Company shall execute and the Trustee shall authenticate and deliver in exchange therefor one or
more definitive Securities of the same series, of any authorized denominations and of like tenor
and aggregate principal amount. 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.

24

 

SECTION 3.05 Registration; Registration of Transfer and Exchange.

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

     Upon surrender for registration of transfer of any Security of a series at the office or
agency of the Company in a Place of Payment for that 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 like tenor
and aggregate principal amount.

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

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

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

     If the Securities of any series (or of any series and specified tenor) are to be redeemed in
part, the Company shall not be required (A) to issue, register the transfer of or exchange any
Securities of that series (or of that series and specified tenor, as the case may be) during a
period beginning at the opening of business 15 days before the day of the mailing of a notice of
redemption of any such Securities selected for redemption under Section 11.03 and ending at the
close of business on the day of such mailing, or (B) 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.

25

 

     None of the Company, the Trustee, any Paying Agent or the Securities Registrar will have any
responsibility or liability for any aspect of the Depositary’s records relating to or payments made
on account of beneficial ownership interests in a Global Security or for maintaining, supervising
or reviewing any records relating to such beneficial ownership interests.

SECTION 3.06 Mutilated, Destroyed, Lost and Stolen Securities.

     If any mutilated Security is surrendered to the Trustee, 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 and bearing a number not contemporaneously outstanding.

     If there shall be delivered to the Company and the Trustee (i) evidence to their satisfaction
of the destruction, loss or theft of any Security 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 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.

     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.

     Except as 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 at the close of business on the Regular Record Date for
such interest.

26

 

     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 given to each Holder of Securities of such series in the manner set forth in Section
1.06, 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 as the owner of such Security for the purpose of receiving payment of principal of and
any premium and (subject to Section 3.07) any interest on such Security and for all other purposes
whatsoever, whether or not such Security be overdue, and neither the

27

 

Company, the Trustee nor any agent of the Company or the Trustee shall be affected by notice
to the contrary.

     No holder of any beneficial interest in any Global Security held on such holder’s behalf by a
Depositary shall have any rights under this Indenture with respect to such Global Security, 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 for all purposes whatsoever. Notwithstanding the
foregoing, nothing herein shall 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 as Holder of any Security.

     None of the Company, the Trustee, the Paying Agent or the Security Registrar shall have any
responsibility or obligation to any beneficial owner in a Global Security or other Person with
respect to the accuracy of the records of the Depositary or its nominee or of any agent member,
with respect to any ownership interest in the Securities or with respect to the delivery to any
agent member, beneficial owner or other Person (other than the Depositary) of any notice (including
any notice of redemption) or the payment of any amount, under or with respect to such Securities.
All notices and communications to be given to the Holders and all payments to be made to Holders
under the Securities and this Indenture shall be given or made only to or upon the order of the
registered holders (which shall be the Depositary or its nominee in the case of the Global
Security). The rights of beneficial owners in the Global Security shall be exercised only through
the Depositary subject to the applicable procedures. The Trustee, the Paying Agent and the
Security Registrar shall be entitled to rely and shall be fully protected in relying upon
information furnished by the Depositary with respect to its members, participants and any
beneficial owners. The Trustee, the Paying Agent and the Security Registrar shall be entitled to
deal with the Depositary, and any nominee thereof, that is the registered holder of any Global
Security for all purposes of this Indenture relating to such Global Security (including the payment
of principal, premium, if any, and interest and additional amounts, if any, and the giving of
instructions or directions by or to the owner or holder of a beneficial ownership interest in such
Global Security) as the sole holder of such Global Security and shall have no obligations to the
beneficial owners thereof. None of the Company, the Trustee, the Paying Agent or the Security
Registrar shall have any responsibility or liability for any acts or omissions of the Depository
with respect to such Global Security, for the records of any such Depositary, including records in
respect of beneficial ownership interests in respect of any such Global Security, for any
transactions between the Depository and any agent member or between or among the Depositary, any
such agent member and/or any holder or owner of a beneficial interest in such Global Security, or
for any transfer or beneficial interests in any such Global Security.

SECTION 3.09 Cancellation.

     All Securities surrendered for payment, redemption, registration of transfer or exchange or
for credit against any sinking fund payment shall, if surrendered to any Person other than the
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

28

 

all Securities so delivered shall be promptly cancelled by the Trustee. No Securities shall
be authenticated in lieu of or in exchange for any Securities cancelled as provided in this
Section, except as expressly permitted by this Indenture. All cancelled Securities held by the
Trustee shall be disposed of by the Trustee in accordance with its customary procedures.

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 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.

SECTION 3.12 Further Issuances.

     The Company may from time to time without the consent of the Holders of Securities of any
series affected create and issue further Securities of such series having the same terms and
conditions as the Securities of such series in all respects (or in all respects except for the
payment of interest of the Securities of such series (i) scheduled and paid prior to the date of
issuance of the additional Securities of such series or (ii) payable on the first Interest Payment
Date following such issuance) so that such further issues shall be consolidated and form a single
series with the outstanding Securities of any series. Any further Securities forming a single
series with the outstanding Securities of any series may be constituted by the Indenture or any
supplement to this Indenture.

deposited or caused to be deposited with the Trustee as trust funds in trust for the purpose
money in an amount sufficient to pay and discharge the entire indebtedness on such

Paying Agent (including the Company acting as its own Paying Agent) as the Trustee may determine,
to the Persons entitled thereto, of the principal and any premium and interest for whose payment
such money has been deposited with the Trustee.

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):

Indenture (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 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
not less than 25% in principal amount of the Outstanding Securities of that series a written notice
specifying such default or breach and requiring it to be remedied and stating that such notice is a
“Notice of Default” hereunder; or

          (5) the entry by a court having jurisdiction in the premises of (A) a decree or order for

60 consecutive days; or

          (6) the commencement by the Company 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 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 in furtherance of any such action; or

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

SECTION 5.02 Acceleration of Maturity; Rescission and Annulment.

     If an Event of Default (other than an Event of Default specified in Section 5.01(5) or
5.01(6)) with respect to Securities of any series at the time Outstanding occurs and is continuing,
then in every such case the Trustee or the Holders of not less than 25% in principal amount of the
Outstanding Securities of that series may declare the principal amount of all the Securities of
that series (or, if any Securities of that series are Original Issue Discount Securities, such
portion of the principal amount of such Securities as may be specified by the terms thereof) to be
due and payable immediately, by a notice in writing to the Company (and to the Trustee if given by
Holders), and upon any such declaration such principal amount (or specified amount) shall become
immediately due and payable. If an Event of Default specified in Section 5.01(5) or 5.01 (6) with
respect to Securities of any series at the time Outstanding occurs, the principal amount of all the
Securities of that series (or, if any Securities of that series are Original Issue Discount
Securities, such portion of the principal amount of such Securities as may be specified by the
terms thereof) shall automatically, and without any declaration or other action on the part of the
Trustee or any Holder, become immediately due and payable.

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

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

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

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

32

 

          (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

          (2) all Events of Default with respect to Securities of that series, other than the
non-payment of the principal of 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.

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,

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

          (3) default is made in the making or satisfaction of any sinking fund payment or analogous
obligation when the same becomes due pursuant to the terms of any Security and such default
continues for 5 days,

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 any premium
and interest and, to the extent that payment of such interest shall be legally enforceable,
interest on any overdue principal and premium and on any overdue interest, at the rate or rates
prescribed therefor in such Securities, and, in addition thereto, such further amount as shall be
sufficient to cover the costs and expenses of collection, including the 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.

33

 

SECTION 5.04 Trustee May File Proofs of Claim.

     In case of any judicial proceeding relative to the Company or any other obligor upon the
Securities or the property of the Company or such other obligor or their creditors, the Trustee
shall be entitled and empowered, by intervention in such proceeding or otherwise, to take any and
all actions authorized under the such proceeding or otherwise, to take any and all actions
authorized under the Trust Indenture Act in order to have claims of the Holders and the Trustee
allowed in any such proceeding. In particular, the Trustee shall be authorized:

     (i) to file and prove a claim for the whole amount of principal (and premium, if any)
and interest owing and unpaid in respect of the Securities in accordance with the terms
thereof 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,
expense, disbursements and advances of the Trustee, its agents and counsel) 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, if the Trustee shall
consent to the making of such payments directly to the Holders, to pay to the Trustee any
amount due to the Trustee 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.

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

SECTION 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, 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 any premium or interest, upon presentation of the Securities

34

 

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; and

     SECOND: To the payment of the amounts then due and unpaid for principal of and any premium 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 amounts due and
payable on such Securities for principal and any premium and interest, respectively.

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 indemnity reasonably satisfactory to
the Trustee against the costs, expenses and liabilities to be incurred in compliance with such
request;

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

          (5) no direction inconsistent with such written request has been given to the Trustee during
such 60-day period by the Holders of a majority in 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 any
premium and (subject to Section 3.07) interest on such Security on the respective Stated Maturities
expressed in such Security (or, in the case of redemption, on the Redemption Date) and to institute
suit for the enforcement of any such payment, and such rights shall not be impaired without the
consent of such Holder.

35

 

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 principal amount of the Outstanding Securities of any series
shall have the right to direct the time, method and place of conducting any proceeding for any
remedy available to the Trustee, or exercising any trust or power conferred on the Trustee, with
respect to the Securities of such series, provided that

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

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

          (3) such direction is not unduly prejudicial to the rights of other Holders.

36

 

SECTION 5.13 Waiver of Past Defaults.

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

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

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

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

SECTION 5.14 Undertaking for Costs.

     All parties to this Indenture agree, and each Holder of any Security by 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 for the merits and good faith of the claims or defenses made by such party
litigant; but the provisions of this Section shall not apply to any suit instituted by the 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 the principal amount of the Outstanding Securities of any
series, or any suit instituted by any Holder for the enforcement of the payment of the principal of
(or premium, if any) or interest on any Security on or after the 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 Usury, Stay or Extension Laws.

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

ARTICLE SIX

THE TRUSTEE

SECTION 6.01 Certain Duties and Responsibilities.

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

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

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

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

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

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

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

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

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

38

 

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

SECTION 6.02 Notice of Defaults.

     Within 90 days after the occurrence of any default hereunder known to the Trustee with respect
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, unless such default shall have been cured or waived; provided, however, that, except in
the case of a default in the payment of the principal of (or premium, if any) or interest on any
Security of such series or in the payment of any sinking 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 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 clauses (3) or (4) of the third paragraph of Section 5.01
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, a default with respect
to Securities of such series.

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

     The Trustee shall not be deemed to have notice of any default or Event of Default unless a
Responsible Officer of the Trustee has actual knowledge thereof or unless written notice of any
event which is in fact such a default is received by a Responsible Officer of the Trustee at the
Corporate Trust Office of the Trustee, and such notice references the Notes and this Indenture.

on its part, rely upon an Officers’ Certificate;

          (4) the Trustee may consult with counsel of its selection and the advice of such counsel or

it by this Indenture at the request or direction of any of the Holders pursuant to this Indenture,

to the Trustee against the costs, expenses and liabilities which might be incurred by it in

hereunder either directly or by or through agents or attorneys and the Trustee shall not be
responsible for any misconduct or negligence on the part of any agent or attorney appointed with
due care by it hereunder;

it in good faith and reasonably believed by it to be authorized or within the discretion or rights
or powers conferred upon it by this Indenture;

Company of Securities or the proceeds thereof.

SECTION 6.05 May Hold Securities.

     The Trustee, any Authenticating Agent, any Paying Agent, any Security Registrar or any other
agent of the Company, in its individual or any other capacity, may become the owner or pledgee of

same rights it would have if it were not Trustee, Authenticating Agent, Paying Agent, Security
Registrar or such other agent.

SECTION 6.06 Money Held in Trust.

     Money held by the Trustee in trust hereunder need not be segregated from other funds except to

(which compensation shall not be limited by any provision of law in regard to the compensation
of a trustee of an express trust);

          (2) except as otherwise expressly provided herein, to reimburse the Trustee upon its request
for all reasonable expenses, disbursements and advances incurred or made by the Trustee in
accordance with any provision of this Indenture (including the reasonable compensation and the
expenses and disbursements of its agents and counsel), except any such expense, disbursement or
advance as may be attributable to its negligence, willful misconduct or bad faith; and

          (3) to indemnify each of the Trustee and any predecessor Trustee and their officers, agents,
directors and employees for, and to hold them harmless against, any and all loss, liability,
damage, claim or expense, including taxes (other than taxes based on the income of the Trustee)
incurred without negligence, willful misconduct or bad faith on its part, arising out of or in
connection with the acceptance or administration of the trust or trusts hereunder, including the
costs and expenses of defending itself against any claim (whether against the Company, a Holder or
any other Person) or liability in connection with the exercise or performance of any of its powers
or duties hereunder or in connection with enforcing the Provisions of this Section 6.07.

manner provided by, and subject to the provisions of, the Trust Indenture Act and this Indenture.

SECTION 6.09 Corporate Trustee Required; Eligibility.

     There shall at all times be one (and only one) Trustee hereunder with respect to the
Securities of each series, which may be Trustee hereunder for Securities of one or more other
series. Each Trustee shall be a Person that is eligible pursuant to the Trust Indenture Act to act
as such, and has a combined capital and surplus of at least $50,000,000. If any such Person
publishes reports of condition at least annually, pursuant to law or to the requirements of its
supervising or examining authority, then for the purposes of this Section and to the extent
permitted by the Trust Indenture Act, the combined capital and surplus of such Person shall be
deemed to be its combined capital and surplus as set forth in its most recent report of condition
so published. If at any time the Trustee with respect to the Securities of any series shall cease
to

42

 

be eligible in accordance with the provisions of this Section, it shall resign immediately in
the manner and with the effect hereinafter specified in this Article.

SECTION 6.10 Resignation and Removal; Appointment of Successor.

     (a) No resignation or removal of the Trustee and no appointment of a successor Trustee
pursuant to this Article shall become effective until the acceptance of appointment by the
successor Trustee in accordance with the applicable requirements of Section 6.11.

     (b) The Trustee may resign at any time with respect to the Securities of one or more series by
giving written notice thereof to the Company. If the 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, at the expense of the
Company, any court of competent jurisdiction for the appointment of a successor Trustee with
respect to the Securities of such series.

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

     (d) If at any time:

          (1) the Trustee shall fail to comply with Section 6.08 after written request therefor by the
Company or by any Holder who has been a bona fide Holder of a Security for at least six months, or

          (2) the Trustee shall cease to be eligible under Section 6.09 and shall fail to resign after
written request therefor by the Company or by any such Holder, or

          (3) the Trustee shall become incapable of acting or shall be adjudged a bankrupt or insolvent
or a receiver of the Trustee or of its property shall be appointed or any public officer shall take
charge or control of the Trustee or of its property or affairs for the purpose of rehabilitation,
conservation or liquidation, then, in any such case, (A) the Company by a Board Resolution may
remove the Trustee with respect to all Securities, or (B) subject to Section 5.14, any Holder who
has been a bona fide Holder of a Security for at least six months may, on behalf of himself and all
others similarly situated, petition any court of competent jurisdiction for the removal of the
Trustee with respect to 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 a Board Resolution, shall promptly appoint a successor Trustee or Trustees
with respect to the Securities of that or those series (it being understood that any such successor
Trustee may be appointed with respect to the Securities of one or more or all of such

43

 

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 to all Holders of Securities of such series in the manner provided in
Section 1.06. 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.

     The provisions of this Section shall survive the termination of this Indenture.

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 (including fees and expenses of
its agents and counsel), execute and deliver an instrument transferring to such successor Trustee
all the rights, powers and trusts of the retiring Trustee and shall duly assign, transfer and
deliver to such successor Trustee all property and money held by such retiring Trustee hereunder.

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

44

 

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, upon payment of
fees and expenses of its agents and counsel, duly assign, transfer and deliver to such successor
Trustee all property and money held by such retiring Trustee hereunder with respect to the
Securities of that or those series to which the appointment of such successor Trustee relates.

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

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

SECTION 6.12 Merger, Conversion, Consolidation or Succession to Business.

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

SECTION 6.13 Preferential Collection of Claims Against Company.

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

SECTION 6.14 Appointment of Authenticating Agent.

     The Trustee may appoint an Authenticating Agent or Agents with respect to one or more series
of Securities which shall be authorized to act on behalf of the Trustee to authenticate Securities
of such series issued upon original issue and upon exchange, registration of transfer or partial
redemption thereof or pursuant to Section 3.06, and Securities so authenticated shall be

45

 

entitled to the benefits of this Indenture and shall be valid and obligatory for all purposes
as if authenticated by the Trustee hereunder. Wherever reference is made in this Indenture to the
authentication and delivery of Securities by the Trustee or the Trustee’s certificate of
authentication, such reference shall be deemed to include authentication and delivery on behalf of
the Trustee by an Authenticating Agent and a certificate of authentication executed on behalf of
the Trustee by an Authenticating Agent. Each Authenticating Agent shall be acceptable to the
Company and shall at all times be a corporation organized and doing business under the laws of the
United States of America, any State thereof or the District of Columbia, authorized under such laws
to act as Authenticating Agent, having a combined capital and surplus of not less than $50,000,000
and subject to supervision or examination by Federal or State authority. If such Authenticating
Agent publishes reports of condition at least annually, pursuant to law or to the requirements of
said supervising or examining authority, then for the purposes of this Section, the combined
capital and surplus of such Authenticating Agent shall be deemed to be its combined capital and
surplus as set forth in its most recent report of condition so published. If at any time an
Authenticating Agent shall 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 Person into which an Authenticating Agent may be merged or converted or with which it may
be consolidated, or any Person resulting from any merger, conversion or consolidation to which such
Authenticating Agent shall be a party, or any person succeeding to all or substantially all of the
corporate agency or corporate trust business of an Authenticating Agent, shall continue to be an
Authenticating Agent, provided such Person shall be otherwise eligible under this Section, without
the execution or filing of any paper or any further act on the part of the Trustee or the
Authenticating Agent.

     An Authenticating Agent may resign at any time by giving written notice thereof to the Trustee
and to the Company. The Trustee may at any time terminate the agency of an Authenticating Agent by
giving written notice thereof to such Authenticating Agent and to the Company. Upon receiving such
a notice of resignation or upon such a termination, or in case at any time such Authenticating
Agent shall cease to be eligible in accordance with the provisions of this Section, the Trustee may
appoint a successor Authenticating Agent which shall be acceptable to the Company and shall give
notice of such appointment in the manner provided in Section 1.06 to all Holders of Securities of
the series with respect to which such Authenticating Agent will serve. Any successor
Authenticating Agent upon acceptance of its appointment hereunder shall become vested with all the
rights, powers and duties of its predecessor hereunder, with like effect as if originally named as
an Authenticating Agent. No successor Authenticating Agent shall be appointed unless eligible
under the provisions of this Section.

     The Company agrees to pay to each Authenticating Agent from time to time 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 alternative certificate of authentication in the following form:

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

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

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

     Whenever the Company shall have one or more Paying Agents for any series of Securities, it
will, prior to each due date of the principal of or any premium or interest on any Securities of
that series, deposit with a Paying Agent a sum sufficient to pay such amount, such sum to be held
as provided by the Trust Indenture Act, and (unless such Paying Agent is the Trustee) the Company
will promptly notify the Trustee of its action or failure so to act.

     The Company will cause each Paying Agent 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) comply with the
provisions of the Trust Indenture Act applicable to it as a Paying Agent and (2) during the
continuance of any default by the Company (or any other obligor upon the Securities of that series)
in the making of any payment in respect of the Securities of that series, upon the written request
of the Trustee, forthwith pay to the Trustee all sums held in trust by such Paying Agent for
payment in respect of the Securities of that series.

     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 or any premium or interest on any Security of any series
and remaining unclaimed for two years after such principal, premium 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 Borough of Manhattan, The City of New York, notice that such
money remains unclaimed and that, after a date specified therein, which shall not be less than 30
days from the date of such publication, any unclaimed balance of such money then remaining will be
repaid to the Company.

best knowledge of the signers thereof the Company is in default in the performance and observance
of any of the terms, provisions and conditions of this Indenture (without regard to any period of
grace or requirement of notice provided hereunder) and, if the Company shall be in default,
specifying all such defaults and the nature and status thereof of which they may have knowledge.

     The Company shall deliver to the Trustee, as soon as possible and in any event within five
days after the Company becomes aware of the occurrence of any Event of Default or an event which,
with notice or the lapse of time or both, would constitute an Event of Default, an Officers’
Certificate setting forth the details of such Event of Default or default and the action which the
Company proposes to take with respect thereto.

SECTION 10.05 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 and the rights (charter and
statutory) and franchises of the Company; 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 10.06 Maintenance of Properties.

     The Company will cause all 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.

SECTION 10.07 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.

54

 

SECTION 10.08 Limitation Upon Disposition of Stock of Principal Subsidiary Bank.

     So long as any of the Securities shall be outstanding, neither the Company nor any Subsidiary
will (except to the Company or an Intermediate Subsidiary) sell, assign, transfer, grant a security
interest in or otherwise dispose of any shares of, securities convertible into, or options,
warrants or rights to subscribe for or purchase shares of, Voting Stock (other than directors’
qualifying shares) of any Principal Subsidiary Bank, nor will the Company or any Intermediate
Subsidiary permit any Principal Subsidiary Bank to issue (except to the Company or an Intermediate
Subsidiary) any shares of, or securities convertible into, or options, warrants or rights to
subscribe for or purchase shares of, Voting Stock of such Principal Subsidiary Bank (other than
directors’ qualifying shares) nor will the Company permit any Intermediate Subsidiary that owns any
shares of, or securities convertible into, or options, warrants or rights to subscribe for or
purchase shares of, Voting Stock of any Principal Subsidiary Bank to cease to be an Intermediate
Subsidiary, except that the Company or an Intermediate Subsidiary may make any such sale,
assignment, transfer, or grant of a security interest or other disposition (A)(i) for fair market
value on the date thereof, as determined by the Board of Directors of the Company (which
determination shall be conclusive), and evidenced by a duly adopted resolution thereof, and (ii) in
each such case, after giving effect thereto, the Company and any one or more Intermediate
Subsidiaries will own at least 80% of the Voting Stock of the Principal Subsidiary Bank then issued
and outstanding free and clear of any security interest or (B) in compliance with an order of a
court or regulatory authority of competent jurisdiction. Notwithstanding the foregoing, a
Principal Subsidiary Bank may be merged into or consolidated with another banking institution
organized under the laws of the United States, any State thereof or the District of Columbia, if
after giving effect to such merger or consolidation the Company and any one or more Intermediate
Subsidiaries own at least 80% of the Voting Stock of such other banking institution and immediately
after giving effect thereto and treating any such resulting bank thereafter as a Principal
Subsidiary Bank for purposes of this Indenture, no Event of Default, and no event which, after
notice or lapse of time or both, would become an Event of Default, shall have happened and be
continuing. For purposes of this Section, an “Intermediate Subsidiary” means a Subsidiary (i) that
is organized under the laws of the United States, any State thereof or the District of Columbia,
and (ii) of which all the shares of each class of Voting Stock issued and outstanding, and all
securities convertible into and options, warrants and rights to subscribe for or purchase shares
of, such Voting Stock, are owned directly by the Company or by another Intermediate Subsidiary,
free and clear of any security interest.

     The provisions of this Section 10.08 shall not prohibit the Company from consolidating with or
merging into any other Person or from conveying, transferring or leasing the Company’s properties
and assets substantially as an entirety to any Person as otherwise permitted pursuant to Article
Eight.

SECTION 10.09 Waiver of Certain Covenants.

     Except as otherwise specified as contemplated by Section 3.01 for Securities of such series,
the Company may, with respect to the Securities of any series, omit in any particular instance to
comply with any term, provision or condition set forth in any covenant provided pursuant to Section
3.01(18), 9.01(2) or 9.01(7) for the benefit of the Holders of such series or in Sections 10.05 to
10.07 inclusive if before the time for such compliance the Holders of not less than a majority in
principal amount of the Outstanding Securities of such series shall, by Act of

55

 

such Holders, either waive such compliance in such instance or generally waive compliance with
such term, provision or condition, but no such waiver shall extend to or affect such term,
provision or condition except to the extent so expressly waived, and, until such waiver shall
become effective, the obligations of the Company and the duties of the Trustee in respect of any
such term, provision or condition shall remain in full force and effect.

SECTION 10.10 Calculation of Original Issue Discount.

     The Company shall file with the Trustee promptly at the end of each calendar year (i) a
written notice specifying the amount of original issue discount (including daily rates and accrual

information relating to such original issue discount as may then be relevant under the Internal
Revenue Code of 1986, as amended from time to time.

     The election of the Company to redeem any Securities shall be evidenced by a Board Resolution

SECTION 11.03 Selection by Trustee of Securities to Be Redeemed.

     If less than all the Securities of any series are to be redeemed (unless all the Securities of
a specified tenor are to be redeemed, the particular Securities to be redeemed shall be selected
not more than 60 days prior to the Redemption Date by the Trustee, from the Outstanding Securities
of such series not previously called for redemption, by such method as the Trustee shall deem fair
and appropriate (but subject to compliance with the rules of any securities exchange on which the
securities of such series may be listed) and which may provide for the selection for redemption of
a portion of the principal amount of any Security of such series, provided that the unredeemed
portion of the principal amount of any Security shall be in an

56

 

authorized denomination (which shall not be less than the minimum authorized denomination) for
such Security. If less than all the Securities of such series and of a specified tenor are to be
redeemed, the particular Securities to be redeemed shall be selected not more than 60 days prior to
the Redemption Date by the Trustee, from the Outstanding Securities of such series and specified
tenor not previously called for redemption in accordance with the preceding sentence.

     The Trustee shall promptly notify the Company in writing of the Securities selected for

          (1) the Redemption Date,

          (2) the Redemption Price,

          (3) if less than all the Outstanding Securities of any series are to be redeemed, the
identification (and, in the case of partial redemption of any such Securities, the principal
amounts) of the particular Securities to be redeemed,

          (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 each such Security is to be surrendered for payment of the
Redemption Price, and

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

     Notice of redemption of Securities to be redeemed at the election of the Company shall be
given by the Company or, at the Company’s request, by the Trustee in the name and at the expense of
the Company.

SECTION 11.05 Deposit of Redemption Price.

     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

57

 

as provided in Section 10.03) an amount of money sufficient to pay the Redemption Price of,
and (except if the Redemption Date shall be an Interest Payment Date) accrued interest on, all the
Securities which are to be redeemed on that date.

SECTION 11.06 Securities Payable on Redemption Date.

     Notice of redemption having been given as aforesaid, the Securities so to be redeemed shall,
on the Redemption Date, become due and payable at the Redemption Price therein specified, and from
and after such date (unless the Company shall default in the payment of the Redemption Price and
accrued interest) such Securities shall cease to bear interest. Upon surrender of any such
Security for redemption in accordance with said notice, such Security shall be paid by the Company
at the Redemption Price, together with accrued interest to the Redemption Date; provided, however,
that, unless otherwise specified as contemplated by Section 3.01, installments of interest whose
Stated Maturity is on or prior to the Redemption Date will be payable to the Holders of such
Securities, or one or more Predecessor Securities, registered as such at the close of business on
the relevant 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 any premium 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 only in part shall be surrendered at a Place of Payment
therefor (with, if the Company or the Trustee so requires, due endorsement by, or a written
instrument of transfer in form satisfactory to the Company and the Trustee duly executed by, the
Holder thereof or his attorney duly authorized in writing), and the Company shall execute, and the
Trustee shall authenticate and deliver to the Holder of such Security without service charge, a new

     The minimum amount of any sinking fund payment provided for by the terms of any Securities 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 such Securities is herein referred to as an “optional sinking
fund payment”. If provided for by the terms of any Securities, the cash amount of any sinking fund
payment may be subject to reduction as provided in Section 12.02.

58

 

     Each sinking fund payment shall be applied to the redemption of Securities as provided for by
the terms of such Securities.

SECTION 12.02 Satisfaction of Sinking Fund Payments with Securities.

     The Company (1) may deliver Outstanding Securities of a series (other than any previously
called for redemption) and (2) may apply as a credit Securities of a series which have been
redeemed either at the election of the Company pursuant to the terms of such Securities or through
the application of permitted optional sinking fund payments pursuant to the terms of such
Securities, in each case in satisfaction of all or any part of any sinking fund payment with
respect to any Securities of such series required to be made pursuant to the terms of such
Securities as and to the extent provided for by the terms of such Securities; provided that the
Securities to be so credited have not been previously so credited. The Securities to be so
credited shall be received and credited for such purpose by the Trustee at the Redemption Price, as
specified in the Securities so to be redeemed, for redemption through operation of the sinking fund
and the amount of such sinking fund payment shall be reduced accordingly.

SECTION 12.03 Redemption of Securities for Sinking Fund.

     Not less than 60 days prior to each sinking fund payment date for any Securities, the Company
will deliver to the Trustee an Officers’ Certificate specifying the amount of the next ensuing
sinking fund payment for such Securities pursuant to the terms of such Securities, the portion
thereof, if any, which is to be satisfied by payment of cash and the portion thereof, if any, which
is to be satisfied by delivering and crediting Securities pursuant to Section 12.02 and will also
deliver to the Trustee any Securities to be so delivered. Not less than 45 days prior to each such
sinking fund payment date, the Trustee shall select the Securities to be redeemed upon such sinking
fund payment date in the manner specified in Section 11.03 and cause notice of the redemption
thereof to be given in the name of and at the expense of the Company in the manner provided in
Section 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 Company’s Option to Effect Defeasance or Covenant Defeasance.

     The Company may elect, at its option at any time, to have Section 13.02 or Section 13.03
applied to any Securities or any series of Securities, as the case may be, designated pursuant to
Section 3.01 as being defeasible pursuant to such Section 13.02 or 13.03, in accordance with any
applicable requirements provided pursuant to Section 3.01 and upon compliance with the conditions
set forth below in this Article. Any such election shall be evidenced by a Board Resolution or in
another manner specified as contemplated by Section 3.01 for such Securities.

SECTION 13.02 Defeasance and Discharge.

     Upon the Company’s exercise of its option (if any) to have this Section applied to any
Securities or any series of Securities, as the case may be, the Company shall be deemed to have

59

 

been discharged from its obligations with respect to such Securities as provided in this
Section on and after the date the conditions set forth in Section 13.04 are satisfied (hereinafter
called “Defeasance”). For this purpose, such Defeasance means that the Company shall be deemed to
have paid and discharged the entire indebtedness represented by such Securities and to have
satisfied all its other obligations under such Securities and this Indenture insofar as such
Securities are concerned (and the Trustee, at the expense of the Company, shall execute proper
instruments acknowledging the same), subject to the following which shall survive until otherwise
terminated or discharged hereunder: (1) the rights of Holders of such 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 any premium and interest on such Securities when
payments are due, (2) the Company’s obligations with respect to such Securities under Sections
3.04, 3.05, 3.06, 10.02 and 10.03, (3) the rights, powers, trusts, duties and immunities of the
Trustee hereunder and (4) this Article. Subject to compliance with this Article, the Company may
exercise its option (if any) to have this Section applied to any Securities notwithstanding the
prior exercise of its option (if any) to have Section 13.03 applied to such Securities.

SECTION 13.03 Covenant Defeasance.

     Upon the Company’s exercise of its option (if any) to have this Section applied to any
Securities or any series of Securities, as the case may be, (1) the Company shall be released from
its obligations under Section 10.07 (and any other Sections applicable to such Securities that are
determined pursuant to Section 3.01 to be subject to this provision), and (2) the occurrence of any
event specified in Sections 5.01(4) (with respect to Section 10.07 or any other Section applicable
to such Securities that are determined pursuant to Section 3.01 to be subject to this provision)
shall be deemed not to be or result in an Event of Default, in each case with respect to such
Securities as provided in this Section on and after the date the conditions set forth in Section
13.04 are satisfied (hereinafter called “Covenant Defeasance”). For this purpose, such Covenant
Defeasance means that, with respect to such Securities, the Company may omit to comply with (and no
Event of Default shall arise out of such non-compliance) and shall have no liability in respect of
any term, condition or limitation set forth in any such specified Section, whether directly or
indirectly by reason of any reference elsewhere herein to any such Section or by reason of any
reference in any such Section to any other provision herein or in any other document, but the
remainder of this Indenture and such Securities shall be unaffected thereby.

SECTION 13.04 Conditions to Defeasance or Covenant Defeasance.

     The following shall be the conditions to the application of Section 13.02 or Section 13.03 to
any securities or any series of Securities, as the case may be:

          (1) The Company shall irrevocably have deposited or caused to be deposited with the Trustee
(or another trustee which satisfies the requirements contemplated by Section 6.09 and agrees to
comply with the provisions of this Article applicable to it) as trust funds in trust for the
purpose of making the following payments, specifically pledged as security for, and dedicated
solely to, the benefits of the Holders of such Securities, (A) in the case of Securities
denominated in a foreign currency, money in such foreign currency or Foreign Government Obligations
of the foreign government or governments issuing such foreign currency which through the scheduled
payment of principal and interest in respect thereof in accordance with their terms will provide,
not later than one day before the due date of any payment, such foreign

60

 

currency in an amount or (B) in the case of Securities denominated in U.S. dollars, U.S.
dollars or U.S. Government Obligations which through the scheduled payment of principal and
interest in respect thereof in accordance with their terms will provide, not later than one day
before the due date of any payment, U.S. dollars in an amount, or (C) a combination of money and
U.S. Government Obligations or Foreign Government Obligations (as applicable), in each case
sufficient, in the opinion of a nationally recognized firm of independent public accountants
expressed in a written certification thereof delivered to the Trustee, to pay and discharge, and
which shall be applied by the Trustee (or any such other qualifying trustee) to pay and discharge,
the principal of and any premium and interest on such Securities on the respective Stated
Maturities, in accordance with the terms of this Indenture and such Securities. As used herein,
“U.S. Government Obligation” means (x) any security which is (i) a direct obligation of the United
States of America for the payment of which the full faith and credit of the United States of
America is pledged or (ii) an obligation of a Person controlled or supervised by and acting as an
agency or instrumentality of the United States of America the payment of which is unconditionally
guaranteed as a full faith and credit obligation by the United States of America, which, in either
case (i) or (ii), is not callable or redeemable at the option of the issuer thereof, and (y) any
depositary receipt issued by a bank (as defined in Section 3(a)(2) of the Securities Act) as
custodian with respect to any U.S. Government Obligation which is specified in Clause (x) above and
held by such bank for the account of the holder of such depositary receipt, or with respect to any
specific payment of principal of or interest on any U.S. Government Obligation which is so
specified and held, provided that (except as required by law) such custodian is not authorized to
make any deduction from the amount payable to the holder of such depositary receipt from any amount
received by the custodian in respect of the U.S. Government Obligation or the specific payment of
principal or interest evidenced by such depositary receipt. As used herein, “Foreign Government
Obligation” means any security denominated in a foreign currency which is (i) a direct obligation
of a foreign government or governments for the payment of which the full faith and credit of such
foreign government or governments is pledged or (ii) an obligation of a Person controlled or
supervised by and acting as an agency or instrumentality of such foreign government or governments
the payment of which is unconditionally guaranteed as a full faith and credit obligation by such
foreign government, which, in either case (i) or (ii) is not callable or redeemable at the option
of the issuer thereof.

          (2) In the event of an election to have Section 13.02 apply to any Securities or any series of
Securities, as the case may be, the Company shall have delivered to the Trustee an Opinion of
Counsel stating that (x) the Company has received from, or there has been published by, the
Internal Revenue Service a ruling or (y) since the date of this instrument, there has been a change
in the applicable Federal income tax law, in either case (x) or (y) to the effect that, and based
thereon such opinion shall confirm that, the Holders of such Securities will not recognize gain or
loss for Federal income tax purposes as a result of the deposit, Defeasance and discharge to be
effected with respect to such Securities and will be subject to Federal income tax on the same
amount, in the same manner and at the same times as would be the case if such deposit, Defeasance
and discharge were not to occur.

          (3) In the event of an election to have Section 13.03 apply to any Securities or any series of
Securities, as the case may be, the Company shall have delivered to the Trustee an Opinion of
Counsel to the effect that the Holders of such Securities will not recognize gain or loss for
Federal income tax purposes as a result of the deposit and Covenant Defeasance to be

61

 

effected with respect to such Securities and will be subject to Federal income tax on the same
amount, in the same manner and at the same times as would be the case if such deposit and Covenant
Defeasance were not to occur.

          (4) The Company shall have delivered to the Trustee an Officer’s Certificate to the effect
that neither such Securities nor any other Securities of the same series, if then listed on any
securities exchange, will be delisted as a result of such deposit.

          (5) No event which is, or after notice or lapse of time or both would become, an Event of
Default with respect to such Securities or any other Securities shall have occurred and be
continuing (A) at the time of such deposit or, (B) with regard to any such event specified in
Sections 5.01(5) and (6), at any time during the period ending on the 123rd day after the date of
such deposit or, if longer, ending on the day following the expiration of the longest preference
period applicable to the Company in respect of such deposit (it being understood that the condition
in this clause (B) is a condition subsequent and shall not be deemed satisfied until the expiration
of such period).

          (6) Such Defeasance or Covenant Defeasance shall not cause the Trustee to have a conflicting
interest within the meaning of the Trust Indenture Act (assuming all Securities are in default
within the meaning of such Act).

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

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

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

SECTION
13.05 Deposited Money and U.S. Government Obligations to Be Held in Trust; Miscellaneous
Provisions.
 

     Subject to the provisions of the last paragraph of Section 10.03, all money, U.S. Government
Obligations and Foreign Government Obligations (including the proceeds thereof) deposited with the
Trustee or other qualifying trustee (solely for purposes of this Section and Section 13.06, the
Trustee and any such other trustee are referred to collectively as the “Trustee”) pursuant to
Section 13.04 in respect of any Securities shall be held in trust and applied by the Trustee, in
accordance with the provisions of such Securities and this Indenture, to the payment, either
directly or through any such Paying Agent (including the Company acting as its own Paying Agent) as
the Trustee may determine, to the Holders of such Securities, of all sums due and to become due
thereon in respect of principal and any premium and interest, but money so held in trust need not
be segregated from other funds except to the extent required by law.

62

 

     The Company shall pay and indemnify the Trustee against any tax, fee or other charge imposed
on or assessed against the U.S. Government Obligations or the Foreign 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
Outstanding Securities.

     Anything in this Article to the contrary notwithstanding, the Trustee shall deliver or pay to
the Company from time to time upon Company Request any money or U.S. Government Obligations or the
Foreign Government Obligations held by it as provided in Section 13.04 with respect to any
Securities which, in the opinion of a nationally recognized firm of independent public accountants
expressed in a written certification thereof delivered to the Trustee, are in excess of the amount
thereof which would then be required to be deposited to effect the Defeasance or Covenant
Defeasance, as the case may be, with respect to such Securities.

SECTION 13.06 Reinstatement.

     If the Trustee or the Paying Agent is unable to apply any money in accordance with this
Article with respect to any Securities by reason of any order or judgment of any court or
governmental authority enjoining, restraining or otherwise prohibiting such application, then the
obligations under this Indenture and such Securities from which the Company has been discharged or
released pursuant to Section 13.02 or 13.03 shall be revived and reinstated as though no deposit
had occurred pursuant to this Article with respect to such Securities, until such time as the
Trustee or Paying Agent is permitted to apply all money held in trust pursuant to Section 13.05
with respect to such Securities in accordance with this Article; provided, however, that if the
Company makes any payment of principal of or any premium or interest on any such Security following
such reinstatement of its obligations, the Company shall be subrogated to the rights (if any) of
the Holders of such Securities to receive such payment from the money so held in trust.

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

63

 

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

includes any successor corporation under the Indenture hereinafter referred to), for value
received, herby promises to pay to

CEDE & CO.

or registered assigns, the principal sum of THREE HUNDRED MILLION DOLLARS ($300,000,000) on March
28, 2016 (the “Stated Maturity”), and to pay interest on said principal sum semiannually in arrears
on March 28 and September 28 in each year (individually referred to as an “Interest Payment Date”
and collectively as the “Interest Payment Dates”), commencing September 28, 2011, at the rate of
5.125% per annum, computed on the basis of a 360-day year consisting of twelve 30-day months, from
March 28, 2011, or from the most recent Interest Payment Date to which interest has been paid or
duly provided for, until the principal hereof is paid or made available for payment. The Interest
so payable, and punctually paid or duly provided for, on any Interest Payment Date will, as provide
in such Indenture, be

 

 

paid to the Person in whose name the Security (or one or more Predecessor Securities) is registered
at the close of business on the Regular Record Date for such interest, which shall be the
15th calendar day (whether or not a Business Day) next preceding such Interest Payment
Date, provided that interest payable on the Stated Maturity shall be payable to the Person
to whom the principal hereof is payable. In the event any Interest Payment Date or the Stated
Maturity is not a Business Day, principal and interest will be paid on the next succeeding Business
Day with the same force and effect as if made on such date and no interest on such payment will
accrue from the after such date, Any such interest not so punctually paid or duly provided for
shall forthwith cease to be payable to the Holder on such Regular Record Date and may either be
paid to the Person in whose name this Security (or one or more Predecessor Securities) is
registered at the close of business on a Special Record Date for the payment of such Defaulted
Interest to be fixed by the Trustee (as defined below), notice of which shall be given to the
Holder of this Security not less than 10 days prior to such Special Record Date, or be paid at any
time in any other lawful manner not inconsistent with the requirements of any securities exchange
on which the Securities may be listed, and upon such notice as may be required by such exchange,
all as more fully provided in such indenture. Payment of the principal of and interest on this
Security due on the Stated Maturity will be made in immediately available funds upon presentation
of this Security, provided that it is presented to the Paying Agent in time for the Paying
Agent to make such payment in such funds in accordance with its normal procedures. For the
purposes of this Security, “Business Day” means each Monday, Tuesday, Wednesday, Thursday and
Friday which is not a day on which banking institutions in the Place of Payment are authorized or
obligated by law or executive order to close. Payment of the principal of (and premium, if any)
and interest on this Security will be made at the office or agency of the Company maintained for
that purpose in The City of New York, New York, which shall initially be the office or agency of
the Trustee, and if this Security is no longer held in global form, in such coin or currency of the
United States of America as at the time of payment is legal tender for payment of public and
private debts; provided, however, that, at the option of the Company, payment of
interest (other than interest payable on the Stated Maturity) may be paid by check mailed to the
address of the Person entitled thereto as such address shall appear in the Security Register at the
close of business on the Regular Record Date.

     Reference is hereby made to the further provisions of this Security set forth on the reverse
hereof, which further provisions shall for all purposes have the same effect as if set forth at
this place.

[REVERSE OF SECURITY]

     This Security is one of a duly authorized issue of notes of the series designated above of the
Company (herein called the “Securities”), issued and to be issued in one or more series under an
indenture dated as of March 14, 2011 for senior debt securities, between ASSOCIATED BANC-CORP and
THE BANK OF NEW YORK MELLON TRUST COMPANY, N.A., as trustee (the “Trustee”), as supplemented by the
Board Resolution (as so supplemented, the “Indenture”), and reference is hereby made for a
statement of the respective rights, limitations of rights, duties and immunities thereunder of the
Company, the Trustee and the Holders of the Securities and of the terms upon which the Securities
are, and are to be, authenticated and delivered.

     This Security is one of the series designated on the face hereof, initially limited in
aggregate principal amount equal to $300,000,000 as of the date of this Security. In addition, the
Company may from time to time without the consent of the Holders of Securities create and issue
further securities having the same terms and conditions as the Securities in all respects (or in
all respects except for the issue date and issue price) and so that such further issue shall be
consolidated and form a single series with the outstanding securities of this issue (including the
Securities) or upon such terms as the Company may determine at the time of their issue. References
herein to the Securities include (unless the contest requires otherwise) any other securities
issued as described in this paragraph and forming a single series with the Securities.

     Where the Indenture or this Security provides for notice to the Holder of this Security of any
event, such notice shall be sufficiently given if in writing and mailed, first class, postage
prepaid, to the Holder of this Security at his, her or its address as it appears in the Security
Register, not later than the latest date, and not earlier than the earliest date, prescribed for
the giving of such notice. In case by reason of the suspension of regular mail service or by
reason of any other cause it shall be impracticable to give such notice to the Holder of this
Security by mail, then such notification as shall be made with the approval of the Trustee shall
constitute a sufficient notification for every purpose hereunder. In any case where notice to the
Holder of this Security is given by mail, neither the failure to mail such notice, nor any defect
in any notice so mailed, to the Holder of this Security shall affect the sufficiency of such notice
with respect to other Holders of the Securities.

     On or after February 28, 2016, the Securities are subject to redemption in whole or in part,
upon not less than 10 days nor more than 60 days’ prior notice, at the election of the Company, at
a redemption price (“Redemption Price”) equal to 100% of the principal amount of the Securities to
be redeemed, plus accrued interest at the Redemption Date.

     Notice of redemption may be delivered electronically or mailed by first-class mail to each
Holder of Securities to be redeemed at his, her to its registered address and will be deemed to
have been given on the first Business Day after electronic delivery or the second Business Day
after the date of mailing. The Securities may be redeemed in part but only in whole multiples of
$10,000,000. Delivery of a notice shall in no way preclude the ability of any Holder to sell or
transfer the Securities prior to the Redemption Date specified in such notice. If

 

 

notice of redemption has been given as provided for by the Indenture, the Securities so to be
redeemed shall, on the Redemption Date, become due and payable at the Redemption Price therein
specified and from and after such date (unless the Company shall default in the payment of the
Redemption Price) such Securities shall cease to bear interest.

     This Security is not mandatorily redeemable, in whole or in part, prior to the Stated
Maturity. This Security is not subject to any sinking fund.

     This Security shall have the benefit of the covenants and agreements set forth in the
Indenture.

     If an Event of Default with respect to the Securities shall occur and be continuing, the
principal of all the securities may be declared due and payable in the manner and with the effect
provided in the Indenture.

     The Indenture permits, with certain exceptions as therein provided, the amendment thereof and
the modifications of the rights and obligations of the Company and the rights of the Company and
the rights of the Holders of the Securities of each series under the indenture to be affected at
any time by the Company with the consent of the Holders of a majority in principal amount of the
Outstanding Securities, and with respect to certain limited matters, the Company and the Trustee
may enter into one or more indentures supplemental to the indenture without the consent of any
Holder. The Indenture also contains provisions permitting the holders of a majority in principal
amount of the Outstanding Securities of each series, on behalf of the Holders of all Securities of
such series, to waive certain past defaults under the Indenture and their consequences. Any such
consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder
and upon all future Holders of this Security and of any Security issued upon the registration of
transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent
or waiver is made upon this Security.

     As provided in and subject to the provisions of the Indenture, the Holder of this Security
shall not have the right to institute any proceeding, judicial or otherwise, with respect to the
Indenture, or for the appointment of a receiver or trustee, or for any other remedy thereunder,
unless such Holder has previously given written notice to the Trustee of a continuing Event of
Default with respect to the Securities, the Holders of not less than 25% in principal amount of the
Outstanding Securities 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, such Holder or Holders have
offered to the Trustee indemnity reasonably satisfactory to it against the costs, expenses and
liabilities to be incurred in compliance with such request, the Trustee for 60 days after its
receipt of such notice, request and offer of indemnity has failed to institute such proceeding, and
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. The
foregoing shall not apply to any suit instituted by the Holder of this Security for the enforcement
of any payment of principal of, premium, if any, and interest on this Security on or after the
respective due dates expressed herein.

     No reference herein to the Indenture and no provision of this Security or of the Indenture
shall alter or impair the obligation of the Company which is absolute and unconditional to pay

 

 

the principal of premium, if any, and interest on this Security at the times, places and rate,
and in the coin or currency herein and in the Indenture prescribed.

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

     The Securities are issuable only in fully registered form without coupons, in denominations of
$2,000 and integral multiples of $1,000 in excess thereof. As provided in the Indenture and
