     In determining whether the Holders of the requisite principal amount of such Securities
Outstanding have given any request, demand, authorization, direction, notice, consent or waiver
hereunder, the principal amount of any Original Issue Discount Security that shall be deemed to be
Outstanding shall be the amount of the principal thereof that would be due and payable as of the
date of such determination upon a declaration of acceleration of the Maturity thereof. In
determining whether the Holders of the requisite principal amount of such Securities Outstanding
have given a direction concerning the time, method, and place of conducting any proceeding for any
remedy available to the Trustee, or concerning the exercise of any trust or power conferred upon

Securities to the waiver of any past default and its consequences, Securities owned by the Company,
any other obligor upon the Securities, or any Affiliate of the Company or such other obligor shall

waiver, only Securities which a Responsible Officer assigned to the corporate trust department of
the Trustee knows to be owned by the Company or any other obligor upon the Securities or any
Affiliate of the Company or such other obligor 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

that the pledgee is not the Company or any other obligor upon the Securities or any Affiliate of
the Company or such other obligor.

7

 

Indenture with respect to any action to be taken by the Trustee (except for the Officers’

     (a) a statement that each individual signing such certificate or opinion has read all
covenants and conditions of this Indenture relating to such proposed action, including the
definitions herein relating thereto;

     (b) a brief statement as to the nature and scope of the examination or investigation upon
which the statements or opinions contained in such certificate or opinion are based;

     (c) a statement that, in the opinion of each such individual, he or she has made such
examination or investigation as is necessary to enable him or her to express an informed opinion as
to whether or not such covenant or condition has been complied with; and

     (d) a statement as to whether, in the opinion of each such individual, such condition or
covenant has been complied with.

     Section 1.03 Form of Documents Delivered to Trustee. In any case where several
matters are required to be certified by, or covered by an opinion of, any specified Person, it is
not necessary that all such matters be certified by, or covered by the opinion of, only one such
Person, or that they be so certified or covered by only one document, but one such Person may
certify or give an opinion with respect to some matters and one or more other such Persons as to

legal matters, upon a certificate or opinion of, or representations by, legal counsel, unless such
officer knows that any such certificate, opinion, or representation is erroneous. Any opinion of
counsel for the Company may be based, insofar as it relates to factual matters, upon a certificate
or opinion of, or representations by, an officer or officers of the Company, unless such counsel

consents, certificates, statements, opinions, or other instruments under this Indenture, such
instruments may, but need not, be consolidated and form a single instrument.

     Section 1.04 Acts of Securityholders.

     (a) Any request, demand, authorization, direction, notice, consent, waiver, or other action
provided by this Indenture to be given or taken by Securityholders may be embodied in and evidenced
by one or more instruments of substantially similar tenor signed by such Securityholders in person
or by an agent duly appointed in writing; and, except as herein otherwise expressly provided, such
action shall become effective when such instrument or instruments are delivered to the Trustee and
(if expressly required by the applicable terms of this Indenture) to the Company. If any
Securities are denominated in coin or currency other than that of the United States, then for the
purposes of determining whether the Holders of the requisite principal amount of Securities have
taken any action as herein described, the principal amount of such Securities shall be deemed to be
that amount of United States dollars that could be obtained

8

 

for such principal amount on the basis of the spot rate of exchange into United States dollars
for the currency in which such Securities are denominated (as evidenced to the Trustee by a
certificate provided by a financial institution, selected by the Company, that maintains an active
trade in the currency in question, acting as conversion agent) as of the date the taking of such
action by the Holders of such requisite principal amount is evidenced to the Trustee as provided in
the immediately preceding sentence. Such instrument or instruments (and the action embodied
therein and evidenced thereby) are herein sometimes referred to as the “Act” of the Securityholders
signing such instrument or instruments. Proof of execution of any such instrument or of a writing
appointing any such agent shall be sufficient for any purpose of this Indenture and (subject to
Section 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 to such execution or by the certificate of any notary public
or other officer authorized by law to take acknowledgments of deeds, certifying that the individual
signing such instrument or writing acknowledged to him the execution thereof. Where such execution
is by an officer of a corporation or a member of a partnership, on behalf of such corporation or
partnership, such certificate or affidavit shall also constitute sufficient proof of his authority.
The fact and date of the execution of any such instrument or writing, or the authority of the
person executing the same, may also be proved in any other manner which the Trustee deems
sufficient.

     (c) The ownership of Securities shall for all purposes be determined by reference to the
Security Register, as such register shall exist as of the applicable date.

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

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

     Section 1.05 Notices, etc., to Trustee and Company. Any request, order,
authorization, direction, consent, waiver, or other action to be taken by the Trustee, the Company,
or the Securityholders hereunder (including any Authentication Order), and any notice to be given
to the Trustee or the Company with respect to any action taken or to be taken by the Trustee, the
Company, or the Securityholders hereunder, shall be sufficient if made in writing and

     (a) (if to be furnished or delivered to or filed with the Trustee by the Company or any
Securityholder) delivered to the Trustee at its Corporate Trust Office, Attention:                                 , or

     (b) (if to be furnished or delivered to the Company by the Trustee or any Securityholder, and
except as otherwise provided in Section 5.01(d) and, in the case of a request for repayment, except
as specified in the Security carrying the right to repayment) mailed to the Company, first-class
postage prepaid, at its principal office (as specified in the first paragraph of this instrument),
Attention:                                  , or at any other address hereafter furnished in writing by the Company to
the Trustee.

     Section 1.06 Notice To Securityholders; Waiver. Where this Indenture or any Security
provides for notice to Securityholders of any event, such notice shall be sufficiently given
(unless otherwise expressly provided herein or in such Security) if in writing and mailed,
first-class postage prepaid, to each Securityholder affected by such event, at his or her address
as it appears in the Security Register as of the applicable Record Date, not later than the latest
date or earlier than the earliest date prescribed by this Indenture or such Security for the giving
of such notice. In any case where notice to Securityholders is given by mail, neither the failure
to mail such notice nor any defect in any notice so mailed to any particular Securityholder shall
affect the sufficiency of such notice with respect to other Securityholders. Where this Indenture
or any Security provides for notice in any manner, such notice may be waived in writing by the
Person entitled to receive such notice, either before or after the event, and such waiver shall be
the equivalent of such notice. Waivers of notice by Securityholders shall be filed with the
Trustee, but such filing shall not be a condition precedent to the validity of any action taken in
reliance upon such waiver.

     In case, by reason of the suspension of regular mail service as a result of a strike, work
stoppage or otherwise, it shall be impractical to mail notice of any event to any Securityholder
when such notice is required to be given pursuant to any provision of this Indenture or the
applicable Security, then any method of notification as shall be satisfactory to the Trustee and
the Company shall be deemed to be sufficient for the giving of such notice.

     Section 1.07 Conflict with Trust Indenture Act. If any provision hereof limits,
qualifies or conflicts with another provision hereof which is required to be included in this
Indenture by any of the provisions of the TIA, such required provision shall control.

     Section 1.08 Effect of Headings and Table of Contents. The Article and Section
headings herein and the Table of Contents hereof are for convenience only and shall not affect the
construction of any provision of this Indenture.

10

 

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

     Section 1.12 Governing Law. This Indenture shall be governed by and construed in
accordance with the laws of the State of New York.

     Section 1.13 Counterparts. This instrument may be executed in any number of
counterparts, each of which when so executed shall be deemed to be an original, but all of which
shall together constitute but one and the same instrument.

     Section 1.14 Judgment Currency. The Company agrees, to the fullest extent that it may
effectively do so under applicable law, that (a) if for the purpose of obtaining judgment in any
court with respect to the Securities of any series it is necessary to convert the sum due in
respect of the principal, premium, if any, or interest, if any, payable with respect to such
Securities into a currency in which a judgment can be rendered (the “Judgment Currency”), the rate
of exchange from the currency in which payments under such Securities is payable (the “Required
Currency”) into the Judgment Currency shall be the highest bid quotation (assuming European-style
quotation — i.e., Required Currency per Judgment Currency) received by the Company from three
recognized foreign exchange dealers in the City of New York for the purchase of the aggregate
amount of the judgment (as denominated in the Judgment Currency) on the New York Business Day
preceding the date on which a final unappealable judgment is rendered, for settlement on such
payment date, and at which the applicable dealer timely commits to execute a contract, and (b) the
Company’s obligations under this Indenture to make payments in the Required Currency (i) shall not
be discharged or satisfied by any tender, or by any recovery pursuant to any judgment (whether or
not entered in accordance with the preceding clause (a)), in any currency other than the Required
Currency, except to the extent that such tender or recovery shall result in the actual receipt by
the judgment creditor of the full amount of the Required Currency expressed to be payable in
respect of such payments, (ii) shall be enforceable as an alternative or additional cause of action
for the purpose of recovering in the Required Currency the amount, if any, by which such actual
receipt shall fall short of the full amount of the Required Currency so expressed to be payable,
and (iii) shall not be affected by judgment being obtained for any other sum due under this
Indenture.

     Section 1.15 Legal Holidays. In any case where any Interest Payment Date, Redemption
Date, Repayment Date or Maturity of any Security shall not be a New York Business Day at any Place
of Payment, then (notwithstanding any other provision of this Indenture or of the Securities)
payment of interest or principal (and premium, if any) need not be

11

 

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, Redemption Date, Repayment Date or at Maturity, provided that no interest shall accrue for
the period from and after such Interest Payment Date, Redemption Date, Repayment Date or Maturity,
as the case may be.

          (23) the appointment by the Trustee of an Authenticating Agent in one or more places other
than the Corporate Trust Office of the Trustee, with power to act on behalf of the Trustee, and
subject to its direction, in the authentication and delivery of the Securities of such series;

          (24) any trustees, depositaries, paying agents, transfer agents, exchange agents, conversion
agents, registrars, or other agents with respect to the Securities of such series if other than the
Trustee, Paying Agent and Security Registrar named herein;

          (25) the portion of the principal amount of Securities of such series, if other than the
principal amount thereof, that shall be payable upon declaration of acceleration of the Maturity
thereof pursuant to Section 5.02 or provable in bankruptcy pursuant to Section 5.04;

          (26) any Event of Default with respect to the Securities of such series, if not set forth
herein, or any modification of any Event of Default set forth herein with respect to such series;

15

 

          (27) any covenant solely for the benefit of the Securities of such series;

          (28) the inapplicability of Section 4.02 and Section 4.03 of this Indenture to the Securities
of such series and if Section 4.03 is applicable, the covenants subject to Covenant Defeasance
under Section 4.03; and

          (29) any other terms not inconsistent with the provisions of this Indenture.

     If all of the Securities issuable by or pursuant to any Board Resolution are not to be issued
at one time, it shall not be necessary to deliver the Officers’ Certificate and Opinion of Counsel
required by Section 3.03 hereof at the time of issuance of each such Security, but such Officers’
Certificate and Opinion of Counsel shall be delivered at or before the time of issuance of the
first such Security.

     If any series of Securities shall be established by action taken pursuant to any Board
Resolution, the execution by the officer or officers authorized by such Board Resolution of an
Authentication Order (as defined in Section 3.03 below) with respect to the first Security of such
series to be issued, and the delivery of such Authentication Order to the Trustee at or before the
time of issuance of the first Security of such series, shall constitute a sufficient record of such
action. Except as otherwise permitted by Section 3.03, if all of the Securities of any such series
are not to be issued at one time, the Company shall deliver an Authentication Order with respect to
each subsequent issuance of Securities of such series, but such Authentication Orders may be
executed by any authorized officer or officers of the Company, whether or not such officer or
officers would have been authorized to establish such series pursuant to the aforementioned Board
Resolution.

     Unless otherwise provided by or pursuant to the Board Resolution or supplemental indenture
creating such series (i) a series may be reopened for issuances of additional Securities of such
series, and (ii) all Securities of the same series shall be substantially identical, except for the
initial Interest Payment Date, issue price, initial interest accrual date and the amount of the
first interest payment.

     The form of the Securities of each series shall be established in a supplemental indenture or
by or pursuant to the Board Resolution creating such series. The Securities of each series shall
be distinguished from the Securities of each other series in such manner as the Board of Directors
or its authorized representative or representatives may determine.

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

     Section 3.02 Denominations and Currency. The Securities of each series shall be
issuable in such denominations and currency as shall be provided in the provisions of this
Indenture or by or pursuant to the Board Resolution or supplemental indenture creating such series.
In the absence of any such provisions with respect to the Securities of any series, the Securities
of that series shall be issuable only in fully registered form in denominations of U.S. $1,000 and
any integral multiple thereof.

16

 

     Section 3.03 Execution, Authentication and Delivery, and Dating. The Securities shall
be executed on behalf of the president, any vice president, the treasurer or any assistant
treasurer and attested by the secretary or any one of its assistant secretaries, under its
corporate seal. The signature of any of these officers on the Securities may be manual or
facsimile. The seal of the Company may be in the form of a facsimile thereof and may be impressed,
affixed, imprinted, or otherwise reproduced on the Securities. Typographical and other minor
errors or defects in any such reproduction of the seal or any such signature shall not affect the
validity or enforceability of any Security that has been duly authenticated and delivered by the
Trustee.

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

     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 to the Trustee for authentication, together with a Company Order for
authentication and delivery (such Order an “Authentication Order”) with respect to such Securities,
and the Trustee shall, upon receipt of such Authentication Order, in accordance with procedures
acceptable to the Trustee set forth in the Authentication Order, and subject to the provisions
hereof, authenticate and deliver such Securities to such recipients as may be specified from time
to time pursuant to such Authentication Order. The material terms of such Securities shall be
determinable by reference to such Authentication Order and procedures. If provided for in such
procedures, such Authentication Order may authorize authentication and delivery of such Securities
pursuant to oral instructions from the Company or its duly authorized agent, which instructions
shall be promptly confirmed in writing. 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 the provisions of Section 6.01 hereof) shall be fully
protected in relying upon:

          (1) an executed supplemental indenture, if any;

          (2) an Officers’ Certificate, certifying as to the authorized form or forms and terms of such
Securities; and

          (3) an Opinion of Counsel, stating that:

     (a) the form or forms and terms of such Securities have been established by and in
conformity with the provisions of this Indenture; provided that if all such Securities are
not to be issued at the same time, such Opinion of Counsel may state that such terms will be
established in conformity with the provisions of this Indenture, subject to any conditions
specified in such Opinion of Counsel; and

     (b) 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,

17

 

enforceable in accordance with their terms, subject to bankruptcy, insolvency,
moratorium, reorganization, and other laws of general applicability relating to or affecting
the enforcement of creditors’ rights and to general principles of equity;

provided, however, that if all Securities issuable by or pursuant to a Board Resolution or
supplemental indenture are not to be originally issued at one time, it shall not be necessary to
deliver the Officers’ Certificate or Opinion of Counsel otherwise required pursuant to this
paragraph at or prior to the time of authentication of each such Security if such documents are
delivered at or prior to the time of authentication upon original issuance of the first such
Security to be issued. After the original issuance of the first such Security to be issued, any
separate request by the Company that the Trustee authenticate such Securities for original issuance
will be deemed to be a certification by the Company that it is in compliance with all conditions
precedent provided for in this Indenture relating to the authentication and delivery of such
Securities.

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

     If the Company shall establish pursuant to Section 3.01 that Securities of a series may be
issued in whole or in part in global form, then the Company shall execute, and the Trustee shall
(in accordance with this Section 3.03 and the Authentication Order with respect to such series)
authenticate and deliver, one or more Securities in global form that (i) shall represent and shall
be denominated in an aggregate amount equal to the aggregate principal amount of the Outstanding
Securities of such series to be represented by such one or more Securities in global form, (ii)
shall be registered, in the name of the Depositary for such Security or Securities in global form,
or in the name of a nominee of such Depositary, (iii) shall be delivered to such Depositary or
pursuant to such Depositary’s instruction, and (iv) shall bear a legend substantially as follows:
“Unless and until it is exchanged in whole or in part for Securities in certificated form, this
Security may not be transferred except as a whole by the Depositary to a nominee of the Depositary,
or by a nominee of the Depositary to the Depositary or another nominee of the Depositary, or by the
Depositary or any such nominee to a successor Depositary or a nominee of such successor
Depositary.” Each Depositary designated pursuant to Section 3.01 for a Security in global form
must, at the time of its designation and at all times while it serves as Depositary, be a clearing
agency registered under the Securities Exchange Act of 1934 and any other applicable statute or
regulation.

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

     Section 3.04 Temporary Securities. Pending the preparation of definitive Securities
of any series, the Company may execute, and, upon receipt of the documents required by Sections
2.02, 3.01 and 3.03 hereof, together with an Authentication Order, the Trustee shall authenticate
and deliver, temporary Securities of such series that are printed, lithographed,

18

 

typewritten, mimeographed, or otherwise produced, in any authorized denomination,
substantially of the tenor of the definitive Securities in lieu of which they are issued in
registered form, without coupons, and with such appropriate insertions, omissions, substitutions,
and other variations as the officers executing such Securities may determine, as evidenced by their
execution of such Securities. In the case of Securities of any series for which a temporary
Security may be issued in global form, such temporary global security shall represent all of the
Outstanding Securities of such series and tenor.

     Except in the case of temporary Securities in global form, which shall be exchanged in
accordance with the provisions thereof, if temporary Securities of any series are issued, the
Company will cause definitive Securities of such series to be prepared without unreasonable delay.
After the preparation of definitive Securities, the temporary Securities of such series shall be
exchangeable, at the Corporate Trust Office of the Trustee, or at such other office or agency as
may be maintained by the Company in a Place of Payment pursuant to Section 10.02 hereof, for
definitive Securities of such series having identical terms and provisions, upon surrender of the
temporary Securities of such series, at the Company’s own expense and without charge to the Holder;
and upon surrender for cancellation of any one or more temporary Securities of any series, the
Company shall execute and the Trustee shall authenticate and deliver in exchange therefor a like
principal amount of definitive Securities of such series in authorized denominations containing
identical terms and provisions. Unless otherwise specified as contemplated by Section 3.01 with
respect to a temporary Security in global form, until so exchanged, the temporary Securities of
such series shall in all respects be entitled to the same benefits under this Indenture as
definitive Securities of such series.

     Section 3.05 Registration, Transfer and Exchange. With respect to the Securities of
each series, the Trustee shall keep a register (herein sometimes referred to as the “Security
Register”) which shall provide for the registration of Securities of such series, and for transfers
of Securities of such series, in accordance with information to be provided to the Trustee by the
Company, subject to such reasonable regulations as the Trustee may prescribe. Such register shall
be in written form or in any other form capable of being converted into written form within a
reasonable time. At all reasonable times the information contained in such register or registers
shall be available for inspection at the Corporate Trust Office of the Trustee or at such other
office or agency to be maintained by the Company pursuant to Section 10.02 hereof.

     Upon due presentation for registration of transfer of any Security of any series at the
Corporate Trust Office of the Trustee or at any other office or agency maintained by the Company
with respect to that series pursuant to Section 10.02 hereof, 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 such series of any authorized denominations, of like aggregate
principal amount, tenor, terms and Scheduled Maturity Date.

     Any other provision of this Section 3.05 notwithstanding, unless and until it is exchanged in
whole or in part for the individual Securities represented thereby, in definitive form, a Security
in global form representing all or a portion of the Securities of a series may not be transferred
except as a whole by the Depositary for such series to a nominee of such Depositary, or by a
nominee of such Depositary to such Depositary or another nominee of such Depositary, or by

19

 

such Depositary or any such nominee to a successor Depositary for such series or a nominee of
such successor Depositary.

     At the option of the Holder, Securities of any series may be exchanged for other Securities of
such series of any authorized denominations, of like aggregate principal amount, tenor, terms and
Scheduled Maturity Date, 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 Securityholder making the exchange
is entitled to receive.

     If at any time the Depositary for the Securities of a series represented by one or more
Securities in global form notifies the Company that it is unwilling or unable to continue as
Depositary for the Securities of such series, or if at any time the Depositary for the Securities
of such series shall no longer be eligible under Section 3.03 hereof, the Company, by Company
Order, shall appoint a successor Depositary with respect to the Securities of such series. If a
successor Depositary for the Securities of such series 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 that such Securities be represented by one or more Securities in
global form shall no longer be effective with respect to the Securities of such series and the
Company will execute, and the Trustee, upon receipt of an Authentication Order for the
authentication and delivery of definitive Securities of such series, will authenticate and deliver
Securities of such series in definitive form, in authorized denominations, in an aggregate
principal amount, and of like terms and tenor, equal to the principal amount of the Security or
Securities in global form representing such series, in exchange for such Security or Securities in
global form.

     The Company may at any time and in its sole discretion and subject to the procedures of the
Depositary determine that individual Securities of any series issued in global form shall no longer
be represented by such Security or Securities in global form. In such event the Company will
execute, and the Trustee, upon receipt of an Authentication Order for the authentication and
delivery of definitive Securities of such series and of the same terms and tenor, will authenticate
and deliver Securities of such series in definitive form, in authorized denominations, and in
aggregate principal amount equal to the principal amount of the Security or Securities in global
form representing such series in exchange for such Security or Securities in global form.

     If specified by the Company pursuant to Section 3.01 with respect to a series of Securities
issued in global form, the Depositary for such series of Securities may surrender a Security in
global form for such series of Securities in exchange in whole or in part for Securities of such
series in definitive form and of like terms and tenor on such terms as are acceptable to the
Company and such Depositary. Thereupon, the Company shall execute, and the Trustee upon receipt of
an Authentication Order for the authentication and delivery of definitive Securities of such
series, shall authenticate and deliver, without service charge:

     (a) to each Person specified by such Depositary, a new definitive Security or
Securities of the same series and of the same tenor and terms, in authorized denominations,
in aggregate principal amount equal to and in exchange for such Person’s beneficial interest
in the Security in global form; and

20

 

     (b) to such Depositary, a new Security in global form in a denomination equal to the
difference, if any, between the principal amount of the surrendered Security in global form
and the aggregate principal amount of the definitive Securities delivered to Holders
pursuant to clause (a) above.

     Upon the exchange of a Security in global form for Securities in definitive form, such
Security in global form shall be canceled by the Trustee or an agent of the Company or the Trustee.
Securities issued in definitive form in exchange for a Security in global form pursuant to this
Section 3.05 shall be registered in such names and in such authorized denominations as the
Depositary for such Security in global form, pursuant to instructions from its direct or indirect
participants or otherwise, shall instruct the Trustee or an agent of the Company or the Trustee in
writing. The Trustee or such agent shall deliver such Securities to or as directed by the Persons
in whose names such Securities are so registered or to the Depositary.

     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 transfer or exchange.

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

     Unless otherwise provided in the Security to be transferred or exchanged, no service charge
shall be imposed for any registration of transfer or exchange of Securities, but the Company may
(unless otherwise provided in such Security) require payment of a sum sufficient to cover any tax
or other governmental charge that may be imposed in connection with any transfer or exchange of
Securities, other than exchanges pursuant to Section 3.04, 3.06, 9.06 and 11.07 hereof not
involving any transfer.

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

     Section 3.06 Mutilated, Destroyed, Lost and Stolen Securities. If (i) any mutilated
Security is surrendered to the Trustee, or the Company and the Trustee receive evidence to their
satisfaction of the destruction, loss or theft of any Security, and (ii) there is delivered to the
Company and the Trustee such security or indemnity as may be required by them to save each of them
harmless, then, in the absence of notice to the Company or the Trustee that such Security has been
acquired by a bona fide purchaser, the Company may in its discretion execute and upon

21

 

request of the Company the Trustee shall authenticate and deliver, in exchange for or in lieu
of any such mutilated, destroyed, lost or stolen Security, a new Security of like tenor, terms,
series, Scheduled Maturity Date, and principal amount, bearing a number not contemporaneously
outstanding.

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

     Upon the issuance of any new Security under this Section, the Company may require the payment
of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation
thereto and any other expenses (including the fees and expenses of the Trustee) connected
therewith.

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

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

     Section 3.07 Payment of Interest; Interest Rights Preserved. Interest on any Security
which is payable and is punctually paid or duly provided for on any Interest Payment Date shall, if
so provided in such Security, 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 applicable Record Date,
notwithstanding any transfer or exchange of such Security subsequent to such Record Date and prior
to such Interest Payment Date. (unless such Interest Payment Date is also the date of Maturity of
such Security).

     Any interest on any Security which is payable, but is not punctually paid or duly provided
for, on any Interest Payment Date (herein called “Defaulted Interest”) shall forthwith cease to be
payable to the registered Holder on the applicable Record Date by virtue of his having been such
Holder; and, except as hereinafter provided, such Defaulted Interest may be paid by the Company, at
its election in each case, as provided in clause (a) or clause (b) below:

     (a) The Company may elect to make payment of any Defaulted Interest to the Persons in whose
names any such Securities (or their respective Predecessor Securities) are registered at the close
of business on a Special Record Date for the payment of such Defaulted Interest, which shall be
fixed in the following manner. The Company shall notify the Trustee in writing of the amount of
Defaulted Interest proposed to be paid on each such Security and the date of the proposed payment,
and at the same time the Company 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

22

 

of the Persons entitled to such Defaulted Interest as in this clause provided. Thereupon the
Trustee shall fix a Special Record Date for the payment of such Defaulted Interest which shall be
not more than 15 nor less than 10 days prior to the date of the proposed payment and not less than
10 days after the receipt by the Trustee of the notice of the proposed payment. The Trustee shall
promptly notify the Company of such Special Record Date and, in the name and at the expense of the
Company, shall cause notice of the proposed payment of such Defaulted Interest and the Special
Record Date therefor to be mailed, first-class postage prepaid, to the Holder of each such Security
at his address as it appears in the Security Register, not less than 10 days prior to such Special
Record Date. Notice of the proposed payment of such Defaulted Interest and the Special Record Date
therefor having been mailed as aforesaid, such Defaulted Interest shall be paid to the Persons in
whose names such Securities (or their respective Predecessor Securities) are registered at the
close of business on such Special Record Date and shall no longer be payable pursuant to the
following clause (b).

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

     Interest on Securities of any series that bear interest may be paid by mailing a check to the
address of the Person entitled thereto at such address as shall appear in the Securities Register
for such series or by such other means as may be specified in the form of such Security.

     Subject to the foregoing provisions of this Section 3.07 and the provisions of Section 3.05
hereof, 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 any Security is registered on the applicable Record Date(s) as the
owner of such Security for the purpose of receiving payment of principal, premium, if any,
interest, if any (subject to Sections 3.05 and 3.07 hereof), and any additional amounts payable
with respect to such Security, and for all other purposes whatsoever, whether or not such Security
be overdue, and neither the Company, the Trustee, nor any agent of the Company or the Trustee shall
be affected by notice to the contrary.

     None of the Company, the Trustee, any Authenticating Agent, any Paying Agent, the Security
Registrar, or any Co-Security Registrar will have any responsibility or liability for any aspect of
the records relating to or payments made on account of beneficial ownership interests of a Security
in global form or for maintaining, supervising or reviewing any records relating to such beneficial
ownership interests and each of them may act or refrain from acting without liability on any
information relating to such records provided by the Depositary.

     Section 3.09 Cancellation. All Securities surrendered for payment, redemption,
registration of transfer, exchange, or credit against a sinking or analogous fund shall, if

23

 

surrendered to any Person other than the Trustee, be delivered to the Trustee and, if not
already canceled, shall be promptly canceled by it. The Company 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 all Securities so delivered shall be
promptly canceled by the Trustee. Acquisition of such Securities by the Company shall not operate
as a redemption or satisfaction of the indebtedness represented by such Securities unless and until
the same are delivered to the Trustee for cancellation. No Security shall be authenticated in lieu
of or in exchange for any Securities canceled as provided in this Section, except as expressly
permitted by this Indenture. The Trustee shall dispose of all canceled Securities in accordance
with its customary procedures and deliver a certificate of such disposition to the Company.

     Section 3.10 Computation of Interest. Unless otherwise provided as contemplated in
Section 3.01, interest on the Securities shall be calculated on the basis of a 360-day year of
twelve 30-day months.

ARTICLE IV

SATISFACTION AND DISCHARGE

     Section 4.01 Satisfaction and Discharge of Indenture. This Indenture shall cease to
be of further effect with respect to any series of Securities (except as to any surviving rights of
conversion or transfer or exchange of Securities of such series expressly provided for herein or in
the form of Security for such series and obligations described as surviving below), and the
Trustee, on demand of and at the expense of the Company, shall execute proper instruments
acknowledging satisfaction and discharge of this Indenture as to such series, when

     (a) either

          (i) all Securities of that series theretofore authenticated and delivered (other than (A)
Securities of such series which have been destroyed, lost, or stolen and which have been replaced
or paid as provided in Section 3.06, and (B) Securities of such series for whose payment money has
theretofore been deposited in trust or segregated and held in trust by the Company and thereafter
repaid to the Company or discharged from such trust, as provided in Section 4.07) have been
delivered to the Trustee canceled or for cancellation; or

          (ii) all such Securities of that series not theretofore delivered to the Trustee canceled or
for cancellation

          (A) have become due and payable, or

          (B) will, in accordance with their Scheduled Maturity Date, become due and
payable within one year, or

          (C) are to be called for redemption within one year under arrangements
satisfactory to the Trustee for the giving of notice of redemption by the Trustee in
the name, and at the expense, of the Company, and, in any of the cases described in
subparagraphs (A), (B), or(C) above, the Company has irrevocably deposited or caused
to be deposited with the Trustee, as trust funds in

24

 

trust for the purpose, (x) an amount in money sufficient, (y) U.S. Government
Obligations or Equivalent Government Securities which through the payment of
interest and principal in respect thereof in accordance with their terms will
provide, not later than one day before the due date of any payment, money
sufficient, or (z) a combination of (x) and (y) sufficient, in the opinion with
respect to (y) and (z) of a nationally recognized firm of independent public
accountants expressed in a written certification thereof delivered to the Trustee,
to pay and discharge the entire indebtedness on such Securities with respect to
principal, premium, if any, and interest, if any, to the date of such deposit (in
the case of Securities which have become due and payable), or to the Scheduled
Maturity Date or Redemption Date, as the case may be; provided, however, that if
such U.S. Government Obligations or Equivalent Government Securities are callable
or redeemable at the option of the issuer thereof, the amount of such money, U.S.
Government Obligations, and Equivalent Government Securities deposited with the
Trustee must be sufficient to pay and discharge the entire indebtedness referred to
above if such issuer elects to exercise such call or redemption provisions at any
time prior to the Scheduled Maturity Date or Redemption Date, as the case may be,
and the Company, but not the Trustee, shall be responsible for monitoring any such
call or redemption provision; and

     (b) the Company has paid or caused to be paid all other sums payable hereunder by the Company
with respect to the Securities of such series; and

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

     Notwithstanding the satisfaction and discharge of this Indenture with respect to any series of
Securities, the obligations of the Company under paragraph (a) of this Section 4.01 and its
obligations to the Trustee with respect to that series under Section 6.07 shall survive, and the
obligations of the Trustee under Sections 4.05, 4.07 and 10.03 shall survive.

     Section 4.02 Discharge and Defeasance. The provisions of this Section and Section
4.04 (insofar as relating to this Section) shall apply to the Securities of each series unless
specifically otherwise provided in a Board Resolution or indenture supplemental hereto provided
pursuant to Section 3.01. In addition to discharge of this Indenture pursuant to Section 4.01, in
the case of any series of Securities with respect to which the exact amount described in
subparagraph (a) of Section 4.04 can be determined at the time of making the deposit referred to in
such subparagraph (a), the Company shall be deemed to have paid and discharged the entire
indebtedness on all the Securities of such a series as provided in this Section on and after the
date the conditions set forth in Section 4.04 are satisfied, and the provisions of this Indenture
with respect to the Securities of such series shall no longer be in effect (except as to (i) rights
of registration of transfer and exchange of Securities of such series, (ii) substitution of
mutilated, destroyed, lost or stolen Securities of such series, (iii) rights of Holders of
Securities of such series to receive, solely from the trust fund described in subparagraph (a) of
Section 4.04, payments of principal thereof, premium, if any, and interest, if any, thereon upon

     Section 4.03 Covenant Defeasance. The provisions of this Section and Section 4.04
(insofar as relating to this Section) shall apply to the Securities of each series unless
specifically otherwise provided in a Board Resolution or indenture supplemental hereto provided
pursuant to Section 3.01. In the case of any series of Securities with respect to which the exact

Section 3.01 as being subject to Covenant Defeasance with respect to such series) shall be deemed
not to be or result in a default or an Event of Default, in each case with respect to the
Outstanding Securities of such series as provided in this Section on and after the date the
conditions set forth in Section 4.04 are satisfied (hereinafter called “Covenant Defeasance”), and
the Trustee at the cost and expense of the Company, shall execute proper instruments acknowledging
the same. For this purpose, such Covenant Defeasance means that the Company may omit to comply
with and shall have no liability in respect of any term, condition or limitation set forth in any
such covenant (to the extent so specified in the case of Section 5.01(d)), whether directly or
indirectly by reason of any reference elsewhere herein to any such covenant or by reason of any
reference in any such covenant to any other provision herein or in any other document, but the
remainder of this Indenture and the Securities of such series shall be unaffected thereby.

     Section 4.04 Conditions To Defeasance Or Covenant Defeasance. The following shall be
the conditions to application of either Section 4.02 or Section 4.03 to the Outstanding Securities:

     (a) with reference to Section 4.02 or Section 4.03, the Company has irrevocably deposited or
caused to be irrevocably deposited with the Trustee as funds in trust, specifically pledged as
security for, and dedicated solely to, the benefit of the Holders of Securities of such series (i)
money in an amount, or (ii) U.S. Government Obligations or Equivalent Government

26

 

Securities which through the payment of interest and principal in respect thereof in
accordance with their terms will provide, not later than one day before the due date of any
payment, money in an amount, or (iii) a combination of (i) and (ii), sufficient, in the opinion
(with respect to (ii) and (iii)) of a nationally recognized firm of independent public accountants
expressed in a written certification thereof delivered to the Trustee, to pay and discharge each
installment of principal (including mandatory sinking fund payments) of, premium, if any, and
interest on, the Outstanding Securities of such series on the dates such installments of interest,
premium or principal are due, including upon redemption; provided, however, that if such U.S.
Government Obligations and Equivalent Government Securities are callable or redeemable at the
option of the issuer thereof, the amount of such money, U.S. Government Obligations, and/or
Equivalent Government Securities deposited with the Trustee must be sufficient to pay and discharge
the entire indebtedness referred to above if the issuer of any such U.S. Government Obligations or
Equivalent Government Securities elects to exercise such call or redemption provisions at any time
prior to the Scheduled Maturity Date or Redemption Date of such Securities, as the case may be.
The Company, but not the Trustee, shall be responsible for monitoring any such call or redemption
provision.

     (b) in the case of Defeasance under Section 4.02, the Company has delivered to the Trustee an
Opinion of Counsel based on the fact that (x) the Company has received from, or there has been
published by, the Internal Revenue Service a ruling or (y) since the date hereof, there has been a
change in the applicable United States federal income tax law, in either case to the effect that,
and such opinion shall confirm that, the Holders of the Securities of such series will not
recognize income, gain or loss for federal income tax purposes as a result of such deposit,
defeasance and discharge and will be subject to federal income tax on the same amount and in the
same manner and at the same times, as would have been the case if such deposit, Defeasance and
discharge had not occurred;

     (c) in the case of Covenant Defeasance under Section 4.03, the Company has delivered to the
Trustee an Opinion of Counsel to the effect that, and such opinion shall confirm that, the Holders
of the Securities of such series will not recognize income, gain or loss for federal income tax
purposes as a result of such deposit and Covenant Defeasance and will be subject to federal income
tax on the same amount and in the same manner and at the same times, as would have been the case if
such deposit and Covenant Defeasance had not occurred;

     (d) no Event of Default or event which, with notice or lapse of time or both, would become an
Event of Default with respect to the Securities of such series shall have occurred and be
continuing on the date of such deposit, after giving effect to such deposit or, in the case of a
Defeasance under Section 4.02, no Event of Default specified in Section 5.01(e) or Section 5.01(f)
shall have occurred, at any time during the period ending on the 91st 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 this condition shall
not be deemed satisfied until the expiration of such period);

     (e) such Defeasance or Covenant Defeasance will not cause the Trustee to have a conflicting
interest within the meaning of the TIA, assuming all Securities of a series were in default within
the meaning of the TIA;

27

 

     (f) such Defeasance or Covenant Defeasance will not result in a breach or violation of, or
constitute a default under, any agreement or instrument to which the Company is a party or by which
it is bound;

     (g) such Defeasance or Covenant Defeasance will not result in the trust arising from such
deposit constituting an investment company within the meaning of the Investment Company Act of
1940, as amended, unless the trust is registered under such Act or exempt from registration;

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

     (i) the Company shall have delivered to the Trustee an Officers’ Certificate and an Opinion of
Counsel, each stating that all conditions precedent provided for herein relating to such Defeasance
or Covenant Defeasance, as the case may be, have been complied with.

     Section 4.05 Application of Trust Money; Excess Funds. All money and U.S. Government
Obligations or Equivalent Government Securities (including the proceeds thereof) deposited with the
Trustee pursuant to Section 4.01 or Section 4.04 hereof shall be held in trust and applied by it,
in accordance with the provisions of this Indenture and of the series of Securities in respect of
which it was deposited, to the payment, either directly or through any Paying Agent (including the
Company acting as its own Paying Agent), as the Trustee may determine, to the Persons entitled
thereto, of the principal, premium, if any, and interest, if any, for whose payment such money has
been deposited with the Trustee; but such money need not be segregated from other funds except to
the extent required by law.

     The Company will pay and indemnify the Trustee against any tax, fee or other charge imposed on
or assessed against the cash or U.S. Government Obligations or Equivalent Government Securities
deposited pursuant to Section 4.01 or Section 4.04 hereof 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 the Outstanding Securities.

     Anything in this Article 4 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. Governmental Obligations
or Equivalent Government Securities held by it as provided in Section 4.01 or Section 4.04 which,
in the opinion of a nationally recognized investment bank, appraisal firm or firm of a nationally
recognized firm of independent public accountants expressed in a written certification thereof
delivered to the Trustee, (which may be the opinion delivered under Section 4.01 or Section 4.04,
as applicable), are in excess of the amount thereof that would then be required to be deposited to
effect an equivalent satisfaction and discharge, Covenant Defeasance or Defeasance of the
applicable series.

     Section 4.06 Paying Agent to Repay Moneys Held. Upon the satisfaction and discharge
of this Indenture, all moneys then held by any Paying Agent of the Securities (other than the
Trustee) shall, upon demand of the Company, be repaid to it or paid to the Trustee, and
thereupon such Paying Agent shall be released from all further liability with respect to such
moneys.

28

 

     Section 4.07 Return of Unclaimed Amounts. Any amounts deposited with or paid to the
Trustee or any Paying Agent or then held by the Company, in trust for payment of the principal of,
premium, if any, or interest, if any, on the Securities and not applied but remaining unclaimed by
the Holders of such Securities for two years after the date upon which the principal of, premium,
if any, or interest, if any, on such Securities, as the case may be, shall have become due and
payable, shall be repaid to the Company by the Trustee on Company Request or (if then held by the
Company) shall be discharged from such trust; and the Holder of any of such Securities shall
thereafter look only to the Company for any payment which such Holder may be entitled to collect
(until such time as such unclaimed amounts shall escheat, if at all, to the State of New York) 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. Notwithstanding the foregoing,
the Trustee or Paying Agent, before being required to make any such repayment, may at the expense
of the Company cause to be published once a week for two successive weeks (in each case on any day
of the week) in a newspaper printed in the English language and customarily published at least once
a day at least five days in each calendar week and of general circulation in the Borough of
Manhattan, in the City and State of New York, a notice that said amounts have not been so applied
and that after a date named therein any unclaimed balance of said amounts then remaining will be
promptly returned to the Company.

ARTICLE V

REMEDIES

     Section 5.01 Events of Default. “Event of Default”, wherever used herein, means with
respect to any series of Securities any one of the following events (whatever the reason for such
Event of Default and whether it shall be voluntary or involuntary or be effected by operation of

any administrative or governmental body), unless such event is either inapplicable to a particular
series or it is specifically deleted or modified in the manner contemplated by Section 3.01:

Indenture in respect of the Securities of such series (other than a covenant or warranty in respect
of the Securities of such series a default in the performance of which or the breach of

29

 

which is elsewhere in this Section specifically dealt with), and continuance of such default
or breach for a period of 60 days after there has been given, by registered or certified mail, to
the Company by the Trustee or to the Company and the Trustee by the Holders of at least 25% in the
principal amount of the Outstanding Securities of such 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

     (e) default (i) in the payment of any scheduled principal of or interest on any Indebtedness

in the performance of any other term or provision of any Indebtedness of the Company or any
Subsidiary (other than the Securities) in excess of $10 million principal amount that results in
such Indebtedness becoming or being declared due and payable prior to the date on which it would
otherwise become due and payable, and such acceleration shall not have been rescinded or annulled,
or such Indebtedness shall not have been discharged, within a period of 15 days after there has
been given, by registered or certified mail, to the Company by the Trustee or to the Company and
the Trustee by the Holders of at least 25% in aggregate principal amount of the Securities then
outstanding of any series, a written notice specifying such default or defaults and stating that
such notice is a “Notice of Default” hereunder; or

     (f) the entry against the Company or any Significant Subsidiary of one or more judgments,
decrees or orders by a court having jurisdiction in the premises from which no appeal may be or is
taken for the payment of money, either individually or in the aggregate, in excess of $10 million,
and the continuance of such judgment, decree or order unsatisfied and in effect for any period of
45 consecutive days after the amount thereof is due without a stay of execution; or

     (g) the entry of an order for relief against the Company under the Federal Bankruptcy Act by a
court having jurisdiction in the premises or a decree or order by a court having jurisdiction in
the premises adjudging the Company a bankrupt or insolvent under any other applicable Federal or
State law, or the entry of a decree or order approving as properly filed a petition seeking
reorganization, arrangement, adjustment or composition of or in respect of the Company under the
Federal Bankruptcy Code or any other applicable Federal or State law, or appointing a receiver,
liquidator, assignee, trustee, sequestrator (or other similar official) of the Company or of any
substantial part of its property, or ordering the winding up or liquidation of its affairs, and the

under the Federal Bankruptcy Code or any other applicable Federal or State law, or the consent by
it to the filing of any such petition or to the appointment of a receiver, liquidator, assignee,
trustee, sequestrator (or other similar official) of the Company or of any substantial part of its
property, or the making by it of an assignment for the benefit of creditors, or the admission by it
in writing of its inability to pay its debts generally as they become due, or the taking of
corporate action by the Company in furtherance of any such action; or

30

 

     (i) any other Event of Default provided for with respect to the Securities of such series in
accordance with Section 3.01.

     A default under any indebtedness of the Company other than the Securities will not constitute
an Event of Default under this Indenture, and a default under one series of Securities will not
constitute a default under any other series of Securities. The Trustee shall not be charged with
knowledge of an Event of Default unless a Responsible Officer at the Corporate Trust Office has
actual knowledge thereof.

     Section 5.02 Acceleration of Maturity; Rescission, and Annulment. If any Event of
Default described in Section 5.01 above (other than Event of Default described in Section 5.01(e)
and Section 5.01(f)) shall have occurred and be continuing with respect to any series, then and in
each and every such case, unless the principal of all the Securities of such series shall have
already become due and payable, either the Trustee or the Holders of not less than 51% in aggregate
principal amount of the Securities of such series then Outstanding hereunder, by notice in writing
to the Company (and to the Trustee if given by Holders), may declare the principal amount (or, if
the Securities of such series are Original Issue Discount Securities, such portion of the principal
amount as may be specified in the terms of that series) of all the Securities of such series and
any and all accrued interest thereon to be due and payable immediately, and upon any such
declaration the same shall become and shall be immediately due and payable, any provision of this
Indenture or the Securities of such series to the contrary notwithstanding. If an Event of Default
specified in Section 5.01(e) or Section 5.01(f) occurs, the principal amount of the Securities of
such series and any and all accrued interest thereon shall immediately become and be due and
payable without any declaration or other act on the party of the Trustee or any Holder. No
declaration of acceleration by the Trustee with respect to any series of Securities shall
constitute a declaration of acceleration by the Trustee with respect to any other series of
Securities, and no declaration of acceleration by the Holders of at least 51% in aggregate
principal amount of the Outstanding Securities of any series shall constitute a declaration of
acceleration or other action by any of the Holders of any other series of Securities, in each case
whether or not the Event of Default on which such declaration is based shall have occurred and be
continuing with respect to more than one series of Securities, and whether or not any Holders of
the Securities of any such affected series shall also be Holders of Securities of any other such
affected series.

     At any time after such a declaration of acceleration has been made with respect to the
Securities of any series and before a judgment or decree for payment of the money due has been
obtained by the Trustee as hereinafter in this Article provided, the Holders of not less than 51%
in aggregate principal amount of the Outstanding Securities of such series, by written notice to
the Company and the Trustee, may rescind and annul such declaration and its consequences if all
Events of Default with respect to such series of Securities, other than the nonpayment of the
principal of the Securities of such series which have become due solely by such acceleration, have
been cured or waived as provided in Section 5.13, if such cure or waiver does not conflict with any
judgment or decree set forth in Section 5.01(e) and Section 5.01(f) and if all sums paid or
advanced by the Trustee hereunder and the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel have been paid.

31

 

     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:

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

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

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

     (d) any such default continues for any period of grace provided in relation to such default
pursuant to Section 5.01,

then, with respect to the Securities of such series, the Company will, upon demand of the Trustee,
pay to it, for the benefit of the Holder of any such Security (or the Holders of any such series in
the case of clause (c) above), the whole amount then due and payable on any such Security (or on
the Securities of any such series in the case of clause (c) above) for principal (and premium, if
any) and interest, if any, with interest (to the extent that payment of such interest shall be
legally enforceable) upon the overdue principal (and premium, if any) and upon overdue installments
of interest, if any, at such rate or rates as may be prescribed therefor by the terms of any such
Security (or of Securities of any such series in the case of clause (c) above); and, in addition
thereto, such further amount as shall be sufficient to cover the costs and expenses of collection,
including the reasonable compensation, expenses, disbursements and advances of the Trustee, its
agents and counsel and all other amounts due the Trustee under Section 6.07.

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

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

     Section 5.04 Trustee May File Proofs of Claim. In case of the pendency of any
receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment,
composition, or other judicial proceeding relative to the Company or any other obligor upon the
Securities or the property of the Company or of such other obligor or their creditors, the Trustee

32

 

(irrespective of whether the principal of the Securities shall then be due and payable as
therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have
made any demand on the Company for the payment of overdue principal or interest) shall be entitled
and empowered, by intervention in such proceedings or otherwise,

     (a) to file and prove a claim for the whole amount of principal (or, with respect to Original
Discount Securities, such portion of the principal amount as may be specified in the terms of such
Securities), premium, if any, and interest, if any, owing and unpaid in respect of the Securities,
and to file such other papers or documents as may be necessary and advisable in order to have the
claims of the Trustee (including any claim for the reasonable compensation, expenses,
disbursements, and advances of the Trustee, its agents and counsel, and all other amounts due the
Trustee under Section 6.07) and of the Securityholders allowed in such judicial proceedings, and

     (b) to collect and receive any moneys or other property payable or deliverable on any such
claims and to distribute the same; and any receiver, assignee, trustee, liquidator, sequestrator
(or other similar official) in any such judicial proceeding is hereby authorized by each
Securityholder to make such payments to the Trustee, and in the event that the Trustee shall
consent to the making of such payments directly to the Securityholders, to pay to the Trustee any
amount due to it for the reasonable compensation, expenses, disbursements and advances of the
Trustee and its agent and counsel, and any other amounts due the Trustee under Section 6.07 hereof.

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

     Section 5.05 Trustee May Enforce Claims Without Possession of Securities. All rights
of action and claims under this Indenture or the Securities of any series may be prosecuted and
enforced by the Trustee without the possession of any of the Securities of such series or the
production thereof in any proceeding relating thereto, and any such proceeding instituted by the
Trustee shall be brought in its own name as trustee of an express trust, and any recovery of
judgment shall, after provision for the payment of the reasonable compensation, expenses,
disbursements and advances of the Trustee and its agents and counsel, be for the ratable benefit of
the Holders of the Securities, of the series in respect of which such judgment has been recovered.

     Section 5.06 Application of Money Collected. Any money collected by the Trustee with
respect to a series of Securities pursuant to this Article shall be applied in the following order,
at the date or dates fixed by the Trustee and, in case of the distribution of such money on account
of principal, premium, if any, or interest, if any, upon presentation of the Securities of such
series and the notation thereon of the payment, if only partially paid, and upon surrender thereof,
if fully paid:

     First: To the payment of all amounts due the Trustee under Section 6.07 hereof.

33

 

     Second: To the payment of the amounts then due and unpaid upon the Securities
of that series for principal, premium, if any, interest, if any, and additional amounts, if
any, in respect of which or for the benefit of which such money has been collected, ratably,
without preference or priority of any kind.

     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

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

     (b) the Holders of not less than 51% in principal amount of the Outstanding Securities of such
series shall have made written request to the Trustee to institute proceedings in respect of such
Event of Default in its own name as Trustee hereunder;

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

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

     (e) no direction inconsistent with such written request has been given to the Trustee during
such 60-day period by the Holders of a majority in principal amount of the Outstanding Securities
of such series; it being understood and intended that no one or more Holders of Securities of such
series shall have any right in any manner whatever by virtue of, or by availing of, any provision
of this Indenture to affect, disturb or prejudice the rights of any other Holders of Securities of
such series, or to obtain or to seek to obtain priority or preference over any other such Holders
or to enforce any right under this Indenture, except in the manner herein provided and for the
equal and proportionate benefit of all the Holders of all Securities of such series.

     Section 5.08 Unconditional Right of Securityholders 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,
premium, if any, and (subject to Section 3.07) interest, if any, (and additional amounts, if any)
on such Security on or after the respective payment dates expressed in such Security (or, in the
case of redemption or repayment, on the Redemption Date or Repayment Date, as the case may be) and
to institute suit for the enforcement of any such payment on or after such respective date, and
such right shall not be impaired or affected without the consent of such Holder.

     Section 5.09 Restoration of Rights and Remedies. If the Trustee or any Securityholder
has instituted any proceeding to enforce any right or remedy under this Indenture and such
proceeding has been discontinued or abandoned for any reason, then and in every such case the
Company, the Trustee and the Securityholders shall, subject to any determination in such
proceeding, be restored severally and respectively to their former positions hereunder, and
thereafter all rights and remedies of the Trustee and the Securityholders shall continue as though
no such proceeding had been instituted.

34

 

     Section 5.10 Rights and Remedies Cumulative. No right or remedy herein conferred upon
or reserved to the Trustee or to the Securityholders is intended to be exclusive of any other right
or remedy, and every right or 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 Security to exercise any right or remedy accruing upon any Event of Default shall
impair any such right or remedy or constitute a waiver of any such Event of Default or an
acquiescence therein. Every right and remedy given by this Article or by law to the Trustee or to
the Securityholders may be exercised from time to time, and as often as may be deemed expedient, by
the Trustee or by the Securityholders, as the case may be.

     Section 5.12 Control by Securityholders. The Holders of a majority in principal
amount of the Outstanding Securities of any series shall have the right to direct the time, method
and place of conducting any proceeding for any remedy available to the Trustee or exercising any
trust or power conferred on the Trustee with respect to the Securities of such series, provided
that

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

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

     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 not theretofore cured:

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

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

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

35

 

     Section 5.14 Undertaking for Costs. All parties to this Indenture agree, and each
Holder of any Security by his acceptance thereof shall be deemed to have agreed, that any court may
in its discretion require, in any suit for the enforcement of any right or remedy under this
Indenture, or in any suit against the Trustee for any action taken or omitted by it as Trustee, the
filing by any party litigant in such suit of an undertaking to pay the costs of such suit, and that
such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees,
against any party litigant in such suit, having due regard to the merits and good faith of the
claims or defenses made by such party litigant; but the provisions of this Section shall not apply
to any suit instituted by the Trustee, to any suit instituted by any Securityholder or group of
Securityholders holding in the aggregate more than 10% in principal amount of the Outstanding
Securities of any series to which the suit relates, or to any suit instituted by any Securityholder
for the enforcement of the payment of principal, premium, if any, or interest, if any, on any
Security on or after the respective payment dates expressed in such Security (or, in the case of
redemption or repayment, on or after the Redemption Date or Repayment Date).

     Section 5.15 Waiver of Stay or Extension Laws. The Company covenants (to the extent
that it may lawfully do so) that it will not at any time insist upon, or plead, or in any manner
whatsoever claim or take the benefit or advantage of, any stay or extension law (other than any
bankruptcy 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 VI

THE TRUSTEE

     Section 6.01 Certain Duties and Responsibilities of Trustee.

     (a) Except during the continuance of an Event of Default with respect to any series of
Securities,

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

          (ii) in the absence of bad faith on its part, the Trustee may, with respect to Securities of
such series, conclusively rely 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 on
their face to the requirements of this Indenture (but need not confirm or investigate the accuracy
of calculations or other facts stated therein).

     (b) If an Event of Default with respect to any series of Securities actually known to a
Responsible Officer of the Trustee has occurred and is continuing, the Trustee shall exercise,

36

 

with respect to the Securities of such series, such of the rights and powers vested in it by
this Indenture, and use the same degree of care and skill in their exercise, as a prudent person
would exercise or use under the circumstances in the conduct of 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

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

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

          (iii) the Trustee shall not be liable with respect to any action taken or omitted to be taken
by it in good faith in accordance with the direction of the Holders of not less than 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 with respect to the
Securities of such series, or exercising any trust or power conferred upon the Trustee, under this
Indenture with respect to the Securities of such series; and

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

     (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 receipt of notice of the
occurrence of any default hereunder with respect to Securities of any series, the Trustee shall
transmit by mail to all Securityholders of such series, as their names and addresses appear in the
Security Register, notice of such default hereunder known to the Trustee, unless such default shall
have been cured or waived; provided, however, that, except in the case of a default in the payment
of the principal, premium, if any, or interest, if any, on any Security of such series or in the
payment of any sinking or purchase fund installment or analogous obligation with respect to
Securities of such series, the Trustee shall be protected in withholding such notice if and so long
as the board of directors, the executive committee or a trust committee of directors and/or
Responsible Officers of the Trustee in good faith determine that the withholding of such notice is
in the interests of the Securityholders of such series and; provided, further, that, in the case of
any default of the character specified in Section 5.01(d) with respect to Securities of such
series, no such notice to Securityholders of such series shall be given until at least 60 days
after the occurrence thereof. For the purpose of this Section, the term “default”, with respect to
Securities

37

 

of any series, means any event which is, or after notice or lapse of time or both would
become, an Event of Default with respect to Securities of such series.

     Section 6.03 Certain Rights of Trustee. Except as otherwise provided in Section 6.01
above:

     (a) the Trustee may rely and shall be protected in acting or refraining from acting upon any
resolution, certificate, statement, instrument, opinion, report, notice, request, direction,
consent, order, bond, debenture or other paper or document believed by it to be genuine and to have
been signed or presented by the proper party or parties;

     (b) any request, direction or order of the Company mentioned herein shall be sufficiently
evidenced by a Company Request or Company Order and any resolution of the Board of Directors may be
sufficiently evidenced by a Board Resolution;

     (c) whenever in the administration of this Indenture the Trustee shall deem it desirable that
a matter be proved or established prior to taking, suffering or omitting any action hereunder, the
Trustee (unless other evidence be herein specifically prescribed) may, in the absence of bad faith
on its part, rely upon an Officers’ Certificate or Opinion of Counsel or both, and shall not be
liable for any action it takes or omits to take in good faith reliance on such certificate or
opinion;

     (d) the Trustee may consult with counsel of its selection and the advice or opinion of such
counsel as to matters of law shall 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;

     (e) the Trustee shall be under no obligation to exercise any of the rights or powers vested in
it by this Indenture at the request or direction of any of the Securityholders pursuant to this
Indenture, unless such Securityholders shall have offered to the Trustee security or indemnity
reasonably satisfactory to the Trustee against the costs, expenses and liabilities which might be
incurred by it in compliance with such request or direction;

     (f) the Trustee shall not be bound to make any investigation into the facts or matters stated
in any resolution, certificate, statement, instrument, opinion, report, notice, request, direction,
consent, order, bond, debenture or other paper or document, but the Trustee, in its discretion, may
make such further inquiry or investigation into such facts or matters as it may see fit, and, if
the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to
examine the books, records and premises of the Company, personally or by agent or attorney; and

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

     Section 6.04 Not Responsible for Recitals or Issuance of Securities. The recitals
contained herein and in the Securities, except the certificates of authentication, shall be taken
as

38

 

the statements of the Company, and the Trustee assumes no responsibility for their
correctness. The Trustee makes no representations as to the validity or sufficiency of this
Indenture or of the Securities. The Trustee shall not be accountable for the use or application by
the Company of Securities or the proceeds thereof.

     Section 6.05 May Hold Securities. The Trustee or any Paying Agent, Security
Registrar, or other agent of the Company, in its individual or any other capacity, may become the
owner or pledgee of Securities and, subject to Sections 6.08 and 6.13 hereof, may otherwise deal
with the Company with the same rights it would have if it were not Trustee, 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 the extent required by law. The Trustee shall be
under no liability for interest on any money received by it hereunder except as otherwise agreed
with the Company.

     Section 6.07 Compensation and Reimbursement. The Company covenants and agrees

     (a) to pay the Trustee from time to time, and the Trustee shall be entitled to, reasonable
compensation for all services rendered by it hereunder (which compensation shall not be limited by
any provision of law in regard to the compensation of a trustee of an express trust);

     (b) 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
reasonable expenses and disbursements of its agents and counsel), except any such expense,
disbursement or advance as may be attributable to its negligence or bad faith; and

     (c) to indemnify the Trustee for, and to hold it harmless against, any loss, liability or
expense incurred without negligence or bad faith on its part, arising out of or in connection with
the acceptance or administration of this trust, including the reasonable costs and expenses of
defending itself against any claim or liability in connection with the exercise or performance of
any of its powers or duties hereunder.

     Without prejudice to any other rights available to the Trustee under applicable law, when the
Trustee incurs expenses or renders services in connection with an Event of Default specified in
Section 5.01(e) and Section 5.01(f) above, such expenses (including the reasonable charges and
expenses of its counsel) and compensation for such services are intended to constitute expenses of
administration under any applicable Federal or State bankruptcy, insolvency, reorganization, or
other similar law.

     The Trustee shall have a lien prior to the Securities upon all property and funds held or
collected by it as such for any amount owing to it or any predecessor Trustee pursuant to this
Section 6.07, except with respect to funds held in trust for the benefit of the Holders of
particular Securities.

39

 

     The provisions of this Section shall survive the satisfaction and discharge of this Indenture.

     Section 6.08 Disqualification; Conflicting Interests. If the Trustee has or shall
acquire any conflicting interest within the meaning of the Trust Indenture Act, it shall either
eliminate such interest or resign as Trustee with respect to one or more series of Securities, to
the extent and in the manner provided by, and subject to the provisions of, the Trust Indenture Act
and this Indenture. To the extent permitted by such Act, the Trustee shall not be deemed to have a
conflicting interest by virtue of being a trustee under this Indenture with respect to Securities
of more than one series or by virtue of being a trustee under: (i) the Indenture dated as of March
13, 2003 between the Company and National City Bank, Trustee, or (ii) the Indenture dated as of
March 1, 1994 between the Company and The First National Bank of Chicago, Trustee.

     Section 6.09 Corporate Trustee Required; Eligibility. There shall at all times be a
Trustee hereunder with respect to each series of Securities that shall be a corporation organized
and doing business under the laws of the United States of America or of any State or Territory
thereof or of the District of Columbia, authorized under such laws to exercise corporate trust
powers, having a combined capital and surplus of at least $50,000,000, and subject to supervision
or examination by Federal or State authority and having its principal office and place of business
in the City of New York, if there be such a corporation having its principal office and place of
business in said City and willing to act as Trustee on customary and usual terms. If such
corporation publishes reports of condition at least annually, pursuant to law or to the
requirements of the aforesaid supervising or examining authority, then for the purposes of this
Section, the combined capital and surplus of such corporation shall be deemed to be its combined
capital and surplus as set forth in its most recent report of condition so published. If at any
time the Trustee with respect to any series of Securities shall cease to be eligible in accordance
with the provisions of this Section, it shall resign immediately in the manner and with the effect
hereinafter specified in this Article.

     Section 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 under Section 6.11.

     (b) The Trustee may resign with respect to any one or more series of Securities at any time by
giving at least 60 days’ written notice thereof to the Company. If an instrument of acceptance by
a successor Trustee shall not have been delivered to the Trustee within 30 days after the giving of
such notice of resignation, the resigning Trustee may petition any court of competent jurisdiction
for the appointment of a successor Trustee.

     (c) The Trustee may be removed with respect to any series of Securities at any time by Act of
the Holders of 66 2/3% in principal amount of the Outstanding Securities of that series, delivered
to the Trustee and to the Company.

     (d) If at any time:

40

 

          (i) the Trustee shall fail to comply with Section 6.08 above with respect to any series of
Securities after written request therefor by the Company or by any Securityholder who has been a
bona fide Holder of a Security of that series for at least 6 months, or

          (ii) the Trustee shall cease to be eligible under Section 6.09 above with respect to any
series of Securities and shall fail to resign after written request therefor by the Company or by
any such Securityholder, or

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

          (iv) the Trustee shall be adjudged a bankrupt or insolvent or a receiver of the Trustee or of
its property shall be appointed or any public officer shall take charge or control of the Trustee
or of its property or affairs for the purpose of rehabilitation, conservation or liquidation, then,
in any such case (A) the Company may remove the Trustee, with respect to the series or, in the case
of clause (iv), with respect to all series, or (B) subject to Section 5.14, any Securityholder who
has been a bona fide Holder of a Security of such series for at least 6 months may, on behalf of
himself and all others similarly situated, petition any court of competent jurisdiction for the
removal of the Trustee and the appointment of a successor Trustee with respect to the series or, in
the case of clause (iv), with respect to all series.

     (e) If the Trustee shall resign, be removed or become incapable of acting with respect to any
series of Securities, or if a vacancy shall occur in the office of Trustee with respect to any
series of Securities for any cause, the Company shall promptly appoint a successor Trustee for that
series of Securities. If, within one year after such resignation, removal or incapacity, or the
occurrence of such vacancy, a successor Trustee with respect to such series of Securities shall be
appointed by Act of the Holders of 66 2/3% 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, become the successor Trustee with respect
to such series and supersede the successor Trustee appointed by the Company with respect to such
series. If no successor Trustee with respect to such series shall have been so appointed by the
Company or the Securityholders of such series and accepted appointment in the manner hereinafter
provided, any Securityholder who has been bona fide Holder of a Security of that series for at
least 6 months may, on behalf of himself and all others similarly situated, petition any court of
competent jurisdiction for the appointment of a successor Trustee with respect to such series.

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

     Section 6.11 Acceptance of Appointment by Successor. Every successor Trustee
appointed hereunder with respect to all series of Securities shall execute, acknowledge and deliver
to the Company and to the predecessor Trustee an instrument accepting such

41

 

appointment, and thereupon the resignation or removal of the predecessor 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 predecessor Trustee with respect to
any such series; but, on request of the Company or the successor Trustee, such predecessor Trustee
shall, upon payment of its reasonable charges, if any, execute and deliver an instrument
transferring to such successor Trustee all the rights, powers and trusts of the predecessor
Trustee, and shall duly assign, transfer and deliver to such successor Trustee all property and
money held by such predecessor Trustee hereunder.

     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 predecessor Trustee and each successor Trustee
with respect to the Securities of any applicable series shall execute and deliver an indenture
supplemental hereto which (1) shall contain such provisions as shall be deemed necessary or
desirable to transfer and to conform to, and to vest in, each successor Trustee all the rights,
powers, trusts and duties of the predecessor Trustee with respect to the Securities of any series
as to which the appointment of such successor Trustee relates and (2) if the predecessor 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 predecessor
Trustee with respect to the Securities of any series as to which the predecessor Trustee is not
being succeeded shall continue to be vested in the predecessor Trustee, and (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; and, on request of the Company or any
successor Trustee, such retiring Trustee shall duly assign, transfer and deliver to such successor
Trustee all property and money held by such retiring Trustee hereunder with respect to the
Securities of that or those series to which the appointment of such successor Trustee relates.

     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.

     No successor Trustee with respect to any series of Securities shall accept its appointment
unless at the time of such acceptance such successor Trustee shall be qualified and eligible with
respect to that series under this Article.

     Notwithstanding replacement of the Trustee pursuant to this Section, the Company’s obligations
under Section 6.07 hereof shall continue for the benefit of the retiring Trustee.

42

 

     Section 6.12 Merger, Conversion, Consolidation or Succession to Business. Any
corporation into which the Trustee may be merged or converted or with which it may be consolidated,
or any corporation resulting from any merger, conversion or consolidation to which the Trustee
shall be a party, or any corporation succeeding to all or substantially all of the corporate trust
business of the Trustee, shall be the successor of the Trustee hereunder, provided that such
corporation shall be otherwise qualified and eligible under this Article, without the execution or
filing of any paper or any further act on the part of any of the parties hereto. In case any
Securities shall have been authenticated, but not delivered, by the Trustee then in office, any
successor Trustee 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 shall become a creditor, of the Company (or of 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 against any such other obligor, as the case may
be).

     Section 6.14 Appointment of Authenticating Agent. At any time when any of the
Securities remain Outstanding the Trustee, with the approval of the Company, may appoint an
Authenticating Agent or Agents with respect to one or more series of Securities which shall be
authorized to act on behalf of the Trustee to authenticate Securities of such series issued upon
exchange, registration of transfer or partial redemption thereof or pursuant to Section 3.06, and
Securities so authenticated shall be entitled to the benefits of this Indenture and shall be valid
and obligatory for all purposes as if authenticated by the Trustee hereunder. Wherever reference
is made in this Indenture to the authentication and delivery of Securities by the Trustee or the
Trustee’s certificate of authentication, such reference shall be deemed to include authentication
and delivery on behalf of the Trustee by an Authenticating Agent and a certificate of
authentication executed on behalf of the Trustee by an Authenticating Agent. Each Authenticating
Agent shall be acceptable to the Company and shall at all times be a corporation organized and
doing business under the laws of the United States of America, any State thereof or the District of
Columbia, authorized under such laws to act as an Authenticating Agent, having a combined capital
and surplus of not less than $50,000,000 and, if other than the Company itself, subject to
supervision or examination by Federal or State authority. If such Authenticating Agent publishes
reports of condition at least annually, pursuant to law or to the requirements of said supervising
or examining authority, then for the purposes of this Section, the combined capital and surplus of
such Authenticating Agent shall be deemed to be its combined capital and surplus as set forth in
its most recent report of condition so published. If at any time an Authenticating Agent shall
cease to be eligible in accordance with the provisions of this Section, such Authenticating Agent
shall resign immediately in the manner and with the effect specified in this Section.

     Any corporation into which an Authenticating Agent may be merged or converted or with which it
may be consolidated, or any corporation resulting from any merger, conversion or consolidation to
which such Authenticating Agent shall be a party, or any corporation succeeding to the corporate
agency or corporate trust business of an Authenticating Agent, shall continue to be an
Authenticating Agent, provided such corporation shall be otherwise eligible under this

43

 

Section, without the execution or filing of any paper or any further act on the part of the
Trustee or the Authenticating Agent.

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

     The Company agrees to pay to each Authenticating Agent from time to time reasonable
compensation for its services under this Section.

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

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

ARTICLE VII

SECURITYHOLDERS’ LISTS AND REPORTS BY TRUSTEE AND COMPANY

     Section 7.01 Company to Furnish Trustee Names and Addresses of Securityholders. The
Company will furnish or cause to be furnished to the Trustee:

     (a) semiannually, not more than 15 days after January 1 and July 1 in each year, in such form
as the Trustee may reasonably require, a list of the names and addresses of the Holders of
Securities of each series as of such date, and

44

 

     (b) at such other times as the Trustee may request in writing, within 30 days after the
receipt by the Company of any such request, a list of similar form and content as of a date not
more than 15 days prior to the time such list is furnished, provided that if the Trustee shall be
the Security Registrar for such series, such list shall not be required to be furnished.

     Section 7.02 Preservation of Information; Communications to Securityholders.

     (a) The Trustee shall preserve, in as current a form as is reasonably practicable, the names
and addresses of Holders of Securities contained in the most recent list furnished to the Trustee
as provided in Section 7.01 and the names and addresses of Holders of Securities received by the
Trustee in its capacity as Security Registrar. The Trustee may destroy any list furnished to it as
provided in Section 7.01 upon receipt of a new list so furnished.

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

          (i) afford such applicants access to the information preserved at the time by the Trustee in
accordance with Section 7.02(a), or

          (ii) inform such applicants as to the approximate number of Holders of Securities of such
series or all Securities, as the case may be, whose names and addresses appear in the information
preserved at the time by the Trustee in accordance with Section 7.02(a), and as to the approximate
cost of mailing to such Securityholders the form of proxy or other communication, if any, specified
in such application.

     If the Trustee shall elect not to afford such applicants access to such information, the
Trustee shall, upon the written request of such applicants, mail to each Holder of a Security of
such series or to all Securityholders, as the case may be, whose names and addresses appear in the
information preserved at the time by the Trustee in accordance with Section 7.02(a), a copy of the
form of proxy or other communication which is specified in such request, with reasonable promptness
after a tender to the Trustee of the material to be mailed and of payment, or provision for the
payment, of the reasonable expenses of mailing, unless within five days after such tender, the
Trustee shall mail to such applicants and file with the Commission, together with a copy of the
material to be mailed, a written statement to the effect that, in the opinion of the Trustee, such
mailing would be contrary to the best interests of the Holders of Securities of such series or all
Securityholders, as the case may be, or would be in violation of applicable law. Such written
statement shall specify the basis of such opinion. If the Commission, after opportunity for a
hearing upon the objections specified in the written statement so filed, shall enter an order
refusing to sustain any of such objections or if, after the entry of an order sustaining one or
more of such objections, the Commission shall find, after notice and opportunity for hearing, that
all

45

 

the objections so sustained have been met and shall enter an order so declaring, the Trustee
shall mail copies of such material to all Securityholders of such series or all Securityholders, as
the case may be, with reasonable promptness after the entry of such order and the renewal of such
tender; otherwise the Trustee shall be relieved of any obligation or duty to such applicants
respecting their application.

     (c) Every Holder of Securities, by receiving and holding the same, agrees with the Company and
the Trustee that neither the Company nor the Trustee shall be held accountable by reason of the
disclosure of any such information as to the names and addresses of the Holders of Securities in
accordance with Section 7.02(b), regardless of the source from which such information was derived,
and that the Trustee shall not be held accountable by reason of mailing any material pursuant to a
request made under Section 7.02(b).

     Section 7.03 Reports by Trustee.

     (a) The Trustee shall transmit to Holders such reports concerning the Trustee and its actions
under this Indenture as may be required pursuant to the Trust Indenture Act at the times and in the

CONSOLIDATION, MERGER, CONVEYANCE OR TRANSFER

     Section 8.01 Company May Consolidate, etc., Only on Certain Terms. The Company shall
not consolidate with or merge into any other corporation or convey or transfer all or substantially
all of its properties and assets and the properties and assets of the Subsidiaries, taken as a
whole, to any Person, unless;

     (a) either the Company shall be the continuing corporation, or the corporation formed by such
consolidation or into which the Company is merged or the Person which acquires by conveyance or
transfer all or substantially all of the properties and assets of the Company and the Subsidiaries,
taken as a whole, shall be a corporation organized and existing under the laws of the United States
of America or any State or the District of Columbia, and shall expressly assume, by an indenture
supplemental hereto, executed and delivered to the Trustee, in form satisfactory to the Trustee,
the due and punctual payment of the principal, premium, if any, and interest, if any, on all the
Securities and the performance of every covenant of this Indenture on the part of the Company to be
performed or observed;

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

     (c) the Company has delivered to the Trustee an Officers’ Certificate and an Opinion of
Counsel to the effect that any such consolidation, merger, conveyance or transfer and any
assumption permitted or required by this Article complies with the provisions of this Article.

     Section 8.02 Successor Corporation Substituted. Upon any consolidation or merger, or
any conveyance or transfer of all or substantially all of the properties and assets of the Company
in accordance with Section 8.01, the successor corporation formed by such consolidation or into
which the Company is merged or the Person to which such conveyance or transfer is made shall
succeed to, and be substituted for, and may exercise every right and power of, the Company under
this Indenture with the same effect as if such successor corporation had been named as the Company
herein and the Company shall thereupon be released from all obligations hereunder and under the
Securities. Such successor corporation thereupon may cause to be signed and may issue any or all
of the Securities issuable hereunder which theretofore shall not have been signed by the Company
and delivered to the Trustee; and, upon the order of such successor corporation, instead of the
Company, and subject to all the terms, conditions and limitations in this Indenture prescribed, the
Trustee shall authenticate and shall deliver any Securities which previously shall have been signed
and delivered by the officers of the Company to the Trustee for authentication, and any Securities
which such successor corporation thereafter shall cause to be signed and delivered to the Trustee
for that purpose. All of the Securities so

47

 

issued shall in all respects have the same legal rank and benefit under this Indenture as the
Securities theretofore or thereafter issued in accordance with the terms of this Indenture as
though all of such Securities had been issued at the date of the execution hereof.

     In case of any such consolidation, merger, sale or conveyance such changes in phraseology and
form (but not in substance) may be made in the Securities thereafter to be issued as may be
appropriate.

of the Holders of Securities of any other series.

     It shall not be necessary for any Act of Securityholders under this Section 9.02 to approve

and will duly comply with all the other terms, agreements and conditions contained in the Indenture
for the benefit of the Securities of such series.

     Section 10.02 Maintenance of Office or Agency. So long as any of the Securities

If at any time the Company shall fail to maintain such office or agency or shall fail to furnish
the Trustee with the address thereof, such presentations, surrenders, notices and demands may be
made or served at the Corporate Trust Office of the Trustee, and the Company hereby appoints the
Trustee its agent to receive all such presentations, surrenders, notices and demands.

     Section 10.03 Money or Security Payments to Be Held in Trust. If the Company shall at
any time act as its own Paying Agent for any series of Securities, it will, on or before each due
date of the principal, premium, if any, or interest, if any, on any of the Securities of such
series, segregate and hold in trust for the benefit of the Holders of the Securities of such series
a sum sufficient to pay such principal, premium, or interest so becoming due until such sums shall
be paid to such Holders of such Securities 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, on or prior to each due date of the principal, premium, if any, or interest, if any, on any
Securities of such series, deposit with a Paying Agent a sum sufficient to pay such principal,
premium, or interest so becoming due, such sum to be held in trust for the benefit of the Holders
of the Securities entitled to the same and (unless such Paying Agent is the Trustee) the Company
will promptly notify the Trustee of its action or failure so to act.

51

 

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

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

     (b) give the Trustee notice of any default by the Company (or any other obligor upon the
Securities of such series) in the making of any such payment of principal, premium, if any, or
interest, if any, on the Securities of such series; and

     (c) at any time during the continuance of any such default, upon the written request of the
Trustee, forthwith pay to the Trustee all sums so held in trust by such Paying Agent.

     The Company may, at any time, for the purpose of obtaining the satisfaction and discharge of
this Indenture with respect to any series of Securities 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 in respect of each and every series of Securities as to which it seeks to
discharge this Indenture or, if for any other purpose, all sums so held in trust by the Company in
respect of all Securities, such sums to be held by the Trustee upon the same trusts as those upon
which such sums were held by the Company 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.

     Section 10.04 Certificate to Trustee. The Company will deliver to the Trustee within
120 days after the end of each fiscal year, an Officers’ Certificate, one of whose signatories
shall be the Company’s principal executive, accounting or financial officer, stating that in the
course of the performance by the signers of their duties as officers of the Company they would
normally have knowledge of any default by the Company in the performance of any of its covenants,
conditions or agreements contained herein (without regard to any period of grace or requirement of
notice provided hereunder), stating whether or not they have knowledge of any such default and, if
so, specifying each such default of which the signers have knowledge and the nature thereof.

ARTICLE XI

REDEMPTION OF SECURITIES

     Section 11.01 Applicability of Article. The Company may reserve the right to redeem
and pay before the Scheduled Maturity Date all or any part of the Securities of any series, either
by optional redemption, sinking or purchase fund or analogous obligation or otherwise, by provision
therefor in the form of Security for such series established and approved pursuant to Section 2.02
and 2.03 or as otherwise provided in Section 3.01, and on such terms as

52

 

are specified in such form or in the indenture supplemental hereto with respect to Securities
of such series as provided in Section 3.01. Redemption of Securities of any series shall be made
in accordance with the terms of such Securities and, to the extent that this Article does not
conflict with such terms, the succeeding Sections of this Article.

     Section 11.02 Election to Redeem; Notice to Trustee. In case of any redemption at the
election of the Company, the Company shall, at least 60 days prior to the Redemption Date fixed by
the Company (unless a shorter notice shall be satisfactory to the Trustee) notify the Trustee in
writing of such Redemption Date and of the principal amount of Securities of such series to be
redeemed. In the case of any redemption of Securities (a) prior to the expiration of any
restriction on such redemption provided in the terms of such Securities or elsewhere in this
Indenture, or (b) pursuant to an election of the Company which is subject to a condition specified
in the terms of such Securities or elsewhere in this Indenture, the Company shall furnish the
Trustee with an Officers’ Certificate evidencing compliance with such restriction or condition.

     Section 11.03 Selection by Trustee of Securities to be Redeemed. If fewer than all
the Securities of any series are to be redeemed, the particular Securities to be redeemed shall be
selected not more than 60 days prior to the Redemption Date by the Trustee, from the Outstanding
Securities of such series not previously called for redemption, by such method as the Trustee shall
deem fair and appropriate, which may include provision for the selection for redemption of portions
of the principal of Securities of such series of a denomination larger than the minimum authorized
denomination for Securities of that series. Unless otherwise provided in the terms of a particular
series of Securities, the portions of the principal of Securities so selected for partial
redemption shall be equal to the minimum authorized denomination of the Securities of such series,
or an integral multiple thereof, and the principal amount which remains outstanding shall not be
less than the minimum authorized denomination for Securities of such series.

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

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

     Section 11.04 Notice of Redemption. Notice of redemption shall be given by
first-class mail, postage prepaid, mailed not fewer than 30 nor more than 60 days prior to the
Redemption Date, to each Holder of Securities to be redeemed, at his or her address appearing in
the Security Register on the applicable Record Date.

     All notices of redemption shall state:

          (1) the Redemption Date;

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

53

 

          (3) if fewer than all Outstanding Securities of any series are to be redeemed, the
identification (and, in the case of partial redemption, the respective principal amounts) of the
Securities to be redeemed, from the Holder to whom the notice is given and that on and after the
date fixed for redemption, upon surrender of such Security, a new Security or Securities of the
same series in the aggregate principal amount equal to the unredeemed portion thereof will be
issued in accordance with Section 11.07;

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

          (5) the place where such Securities are to be surrendered for payment of the Redemption Price,
which shall be the office or agency maintained by the Company in the Place of Payment pursuant to
Section 10.02 hereof; and

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

     Notice of redemption of Securities to be redeemed at the election of the Company shall be
given by the Company or, at the Company’s request, made at least five business days prior to the
date on which notice is to be given, by the Trustee in the name and at the expense of the Company.

     Section 11.05 Deposit of Redemption Price. On or prior to any Redemption Date, the
Company shall deposit with the Trustee or with a Paying Agent (or, if the Company is acting as its
own Paying Agent, segregate and hold in trust as provided in Section 10.03) an amount of money, in
immediately available funds, sufficient to pay the Redemption Price of 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) such Securities shall cease to bear interest.
Upon surrender of such Securities for redemption in accordance with the notice, such Securities
shall be paid by the Company at the Redemption Price. Any installment of interest due and payable
on or prior to the Redemption Date shall be payable to the Holders of such Securities registered as
such on the relevant Record Date according to the terms and the provisions of Section 3.07 above;
unless, with respect to an Interest Payment Date that falls on a Redemption Date, such Securities
provide that interest due on such date is to be paid to the Person to whom principal is payable.

     If any Security called for redemption shall not be so paid upon surrender thereof for
redemption, the principal shall, until paid, bear interest from the Redemption Date at the rate
borne by the Security, or as otherwise provided in such Security.

     Section 11.07 Securities Redeemed in Part. Any Security that is to be redeemed only
in part shall be surrendered at the office or agency maintained by the Company in the Place of
Payment pursuant to Section 10.02 hereof with respect to that series (with, if the Company or the

54

 

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 and at the expense of the Company, a
new Security or Securities of the same series, tenor, terms and Scheduled Maturity Date, of any
authorized denomination as requested by such Holders in aggregate principal amount equal to and in
exchange for the unredeemed portion of the principal of the Security so surrendered.

     Section 11.08 Provisions with Respect to any Sinking Funds. Unless the form or terms
of any series of Securities shall provide otherwise, in lieu of making all or any part of any
mandatory sinking fund payment with respect to such series of Securities in cash, the Company may
at its option (a) deliver to the Trustee for cancellation any Securities of such series theretofore
acquired by the Company, or (b) receive credit for any Securities of such series (not previously so
credited) acquired or redeemed by the Company (other than through operation of a mandatory sinking
fund) and theretofore delivered to the Trustee for cancellation, and if it does so then (i)
Securities so delivered or credited shall be credited at the applicable sinking fund Redemption
Price with respect to Securities of such series, and (ii) on or before the 60th day next preceding
each sinking fund Redemption Date with respect to such series of Securities, the Company will
deliver to the Trustee (A) an Officers’ Certificate specifying the portions of such sinking fund
payment to be satisfied by payment of cash and by the delivery or credit of Securities of such
series acquired or redeemed by the Company, and (B) such Securities, to the extent not previously
surrendered. Such Officers’ Certificate shall also state the basis for any such credit and that
the Securities for which the Company elects to receive credit have not been previously so credited
and were not acquired by the Company through operation of the mandatory sinking fund, if any,
provided with respect to such Securities and shall also state that no Event of Default with respect
to Securities of such series has occurred and is continuing. All Securities so delivered to the
Trustee shall be canceled by the Trustee and no Securities shall be authenticated in lieu thereof.

     If the sinking fund payment or payments (mandatory or optional) with respect to any series of
Securities made in cash plus any unused balance of any preceding sinking fund payments with respect
to Securities of such series made in cash shall exceed $50,000 (or a lesser sum if the Company
shall so request), unless otherwise provided by the terms of such series of Securities, that cash
shall be applied by the Trustee on the sinking fund Redemption Date with respect to Securities of
such series next following the date of such payment to the redemption of Securities of such series
at the applicable sinking fund Redemption Price with respect to Securities of such series, together
with accrued interest, if any, to the date fixed for redemption, with the effect provided in
Section 11.06. The Trustee shall select, in the manner provided in Section 11.03, for redemption
on such sinking fund Redemption Date a sufficient principal amount of Securities of such series to
utilize that cash and shall thereupon cause notice of redemption of the Securities of such series
for the sinking fund to be given in the manner provided in Section 11.04 (and with the effect
provided in Section 11.06) for the redemption of Securities in part at the option of the Company.
Any sinking fund moneys not so applied or allocated by the Trustee to the redemption of Securities
of such series shall be added to the next cash sinking fund payment with respect to Securities of
such series received by the Trustee and, together with such payment, shall be applied in accordance
with the provisions of this Section 11.08. Any and all sinking fund moneys with respect to
Securities of any series held by the

55

 

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

     On or before each sinking fund Redemption Date provided with respect to Securities of any
series, the Company shall pay to the Trustee in cash a sum equal to all accrued interest, if any,
to the date fixed for redemption on Securities to be redeemed on such sinking fund Redemption Date
pursuant to this Section 11.08.

     The Trustee shall not redeem any Securities with sinking fund moneys or give any notice of
redemption of Securities by operation of the applicable sinking fund during the continuance of a
default in payment of interest on Securities of such series or of any Event of Default with respect
to such series, except that if the notice of redemption of any Securities shall theretofore have
been mailed in accordance with the provisions hereof, the Trustee shall redeem such Securities if
cash sufficient for that purpose shall be deposited with the Trustee for that purpose in accordance
with the terms of this Article 11. Except as aforesaid, any moneys in the sinking fund with
respect to Securities of any series at the time when any such default or Event of Default with
respect to such series shall occur, and any moneys thereafter paid into such sinking fund shall,
during the continuance of such default or Event of Default with respect to such series, be held as
security for the payment of all Securities of such series; provided, however, that in case such
default or Event of Default with respect to such series shall have been cured or waived as provided
herein, such moneys shall thereafter be applied on the next sinking fund payment date on which such
moneys may be applied pursuant to the provisions of this Section 11.08.

ARTICLE XII

     Section 12.01 Applicability of Article. Repayment of Securities of any series before

interest thereon accrued to the Repayment Date specified in the terms of such Securities. On or
before the Repayment Date, the Company will deposit with the Trustee or with a Paying Agent (or, if
the Company is acting as its own Paying Agent, segregate and hold in trust as provided in Section
10.03) an amount of money, in immediately available funds, sufficient to pay the Repayment Price of
all the Securities which are to be repaid on such date.

     Section 12.03 Exercise of Option. Securities of any series subject to repayment at
the option of the Holders thereof will contain an “Option to Elect Repayment” form on the reverse
of such Securities. To be repaid at the option of the Holder, any Security so providing for such
repayment, with the “Option to Elect Repayment” form on the reverse of such Security duly completed
by the Holder, must be received by the Company at the Place of

56

 

Payment therefor specified in the terms of such Security (or at such other place or places of
which the Company shall from time to time notify the Holders of such Securities) not earlier than
30 days nor later than 15 days prior to the Repayment Date. If less than the entire principal
amount of such Security is to be repaid in accordance with the terms of such Security, the
principal amount of such Security to be repaid, in increments of $1,000 unless otherwise specified
in the terms of such Security, and the denomination or denominations of the Security or Securities
to be issued to the Holder for the portion of the principal amount of such Security surrendered
that is not to be repaid must be specified. The principal amount of any Security providing for
repayment at the option of the Holder thereof may not be repaid in part, if, following such
repayment, the unpaid principal amount of such Security would be less than the minimum authorized
denomination of Securities of the series of which such Security to be repaid is a part. Except as
otherwise may be provided by the terms of any Security providing for repayment at the option of the
Holder thereof, exercise of the repayment option by the Holder shall be irrevocable unless waived
by the Company.

     Section 12.04 When Securities Presented for Repayment Become Due and Payable. If
Securities of any series providing for repayment at the option of the Holders thereof shall have
been surrendered as provided in this Article and as provided by the terms of such Securities, such
Securities or the portions thereof, as the case may be, to be repaid shall become due and payable
and shall be paid by the Company on the Repayment Date therein specified, and on and after such
Repayment Date (unless the Company shall default in the payment of such Securities on such
Repayment Date) interest on such Securities or the portions thereof, as the case may be, shall
cease to accrue.

     Section 12.05 Securities Repaid in Part. Upon surrender of any Security which is to
be repaid in part only, the Company shall execute and the Trustee shall authenticate and deliver to
the Holder of such Security, without service charge and at the expense of the Company, a new
Security or Securities of the same series, tenor, terms and Scheduled Maturity Date, of any
authorized denomination specified by the Holder, in an aggregate principal amount equal to and in
exchange for the portion of the principal of such Security so surrendered which is not to be
repaid.

ARTICLE XIII

SUBORDINATION OF SUBORDINATED SECURITIES

     Section 13.01 Agreement To Subordinate. The Company covenants and agrees, and each
Holder of any Subordinated Security issued hereunder by his acceptance thereof, whether upon
original issue or upon transfer or assignment, likewise covenants and agrees, that the principal of
(and premium, if any) and interest on each and all of the Subordinated Securities issued hereunder
are hereby expressly subordinated, to the extent and in the manner hereinafter set forth, in right
of payment to the prior payment in full of all Senior Indebtedness.

     Section 13.02 Payment On Dissolution, Liquidation Or Reorganization; Default On Senior
Indebtedness. Upon any payment or distribution of assets or securities of the Company of any
kind or character, whether in cash, property or securities, upon any dissolution or winding up or
total or partial liquidation or reorganization of the Company, whether voluntary or involuntary or
in bankruptcy, insolvency, receivership or other similar proceedings, or upon any assignment

57

 

for the benefit of creditors or any other marshalling of the assets and liabilities of the
Company or otherwise, all principal of (and premium, if any) and interest then due upon all Senior
Indebtedness shall first be paid in full, or payment thereof provided for in money or money’s
worth, before the Holders of the Subordinated Securities or the Trustee on their behalf shall be
entitled to receive any assets or securities (other than shares of stock of the Company as
reorganized or readjusted or securities of the Company or any other corporation provided for by a
plan of reorganization or readjustment, junior to, or the payment of which is subordinated at least
to the extent provided in this Article to the payment of, all Senior Indebtedness which may at the
time be outstanding or any securities issued in respect thereof under any such plan of
reorganization or readjustment) in respect of the Subordinated Securities (for principal, premium
or interest). Upon any such dissolution or winding up or liquidation or reorganization, any
payment or distribution of assets or securities of the Company of any kind or character, whether in
cash, property or securities (other than as aforesaid), to which the Holders of the Subordinated
Securities or the Trustee on their behalf would be entitled, except for the provisions of this
Article, shall be made by the Company or by any receiver, trustee in bankruptcy, liquidating
trustee, agent or other person making such payment or distribution, direct to the holders of Senior
Indebtedness or their representatives to the extent necessary to pay all Senior Indebtedness in
full, in money or money’s worth, after giving effect to any concurrent payment or distribution to
or for the holders of Senior Indebtedness. In the event that, notwithstanding the foregoing, the
Trustee or the Holder of any Subordinated Security shall, under the circumstances described in the
two preceding sentences, have received any payment or distribution of assets or securities of the
Company of any kind or character, whether in cash, property or securities (other than as aforesaid)
before all Senior Indebtedness is paid in full or payment thereof provided for in money or money’s
worth, and if such fact shall then have been made known to the Trustee or, as the case may be, such
Holder, then such payment or distribution of assets or securities of the Company shall be paid over
or delivered forthwith to the receiver, trustee in bankruptcy, liquidating trustee, agent or other
person making payment or distribution of assets or securities of the Company for application to the
payment of all Senior Indebtedness remaining unpaid, to the extent necessary to pay all Senior
Indebtedness in full, in money or money’s worth, after giving effect to any concurrent payment or
distribution to or for the holders of Senior Indebtedness.

     Subject to the payment in full, in money or money’s worth, of all Senior Indebtedness, the
Holders of the Subordinated Securities (together with the holders of any indebtedness of the
Company which is subordinate in right of payment to the payment in full of all Senior Indebtedness
and which is not subordinate in right of payment to the Subordinated Securities) shall be
subrogated to the rights of the holders of Senior Indebtedness to receive payments or distribution
of assets or securities of the Company applicable to Senior Indebtedness until the principal of
(and premium, if any) and interest on the Senior Indebtedness shall be paid in full. No such
payments or distributions applicable to Senior Indebtedness shall, as between the Company, its
creditors other than the holders of Senior Indebtedness, and the Holders of the Subordinated
Securities, be deemed to be a payment by the Company to or on account of the Subordinated
Securities, it being understood that the provisions of this Article are and are intended solely for
the purpose of defining the relative rights of the Holders of the Subordinated Securities, on the
one hand, and the holders of Senior Indebtedness, on the other hand. Nothing contained in this
Article or elsewhere in this Indenture or in the Subordinated Securities is intended to or shall
impair, as between the Company and the Holders of Subordinated Securities, the obligation of the
Company, which is unconditional and absolute, to pay to the Holders of the

58

 

Subordinated Securities the principal of (and premium, if any) and interest on the
Subordinated Securities as and when the same shall become due and payable in accordance with their
terms, or to affect (except to the extent specifically provided above in this paragraph) the
relative rights of the Holders of the Subordinated Securities and creditors of the Company other
than the holders of Senior Indebtedness. Nothing contained herein shall prevent the Trustee or the
Holder of any Subordinated Security from exercising all remedies otherwise permitted by applicable
law upon default under this Indenture, subject to the rights, if any, under this Article, of the
holders of Senior Indebtedness in respect of assets or securities of the Company of any kind or
character, whether cash, property or securities, received upon the exercise of any such remedy.

     Upon any payment or distribution of assets or securities of the Company referred to in this
Article, the Trustee and the Holders of the Subordinated Securities shall be entitled to rely upon
any order or decree of a court of competent jurisdiction in which such dissolution, winding up,
liquidation or reorganization proceedings are pending, and upon a certificate of the receiver,
trustee in bankruptcy, liquidating trustee, agent or other person making any such payment or
distribution, delivered to the Trustee or to the Holders of the Subordinated Securities for the
purpose of ascertaining the persons entitled to participate in such distribution, the holders of
Senior Indebtedness and other indebtedness of the Company, the amount thereof or payable thereon,
the amount or amounts paid or distributed thereon and all other facts pertinent thereto or to this
Article.

     If:

          (i) there shall have occurred a default in the payment on account of the principal of (or
premium, if any) or interest on or other monetary amounts due and payable on any Senior
Indebtedness, or

          (ii) any other default shall have occurred concerning any Senior Indebtedness which permits
the holder or holders thereof to accelerate the maturity of such Senior Indebtedness following
notice, the lapse of time, or both, or

          (iii) during any time Senior Indebtedness is outstanding, the principal of, and accrued
interest on, any series of Subordinated Securities shall have been declared due and payable upon an
Event of Default pursuant to Section 5.02 hereof (and such declaration shall not have been
rescinded or annulled pursuant to this Indenture); then, unless and until such default shall have
been cured or waived or shall have ceased to exist, or such declaration shall have been waived,
rescinded or annulled, no payment shall be made by the Company on account of the principal (or
premium, if any) or interest on the Subordinated Securities.

     The Trustee shall be entitled to rely on the delivery to it of a written notice by a Person
representing himself to be a holder of Senior Indebtedness (or a representative of such holder or a
trustee under any indenture under which any instruments evidencing any such Senior Indebtedness may
have been issued) to establish that such notice has been given by a holder of such Senior
Indebtedness or such representative or trustee on behalf of such holder. In the event that the
Trustee determines in good faith that further evidence is required with respect to the right of any
Person as a holder of Senior Indebtedness to participate in any payment or distribution pursuant to
this Article 13, the Trustee may request such Person to furnish evidence to the

59

 

reasonable satisfaction of the Trustee as to the amount of Senior Indebtedness held by such
Person, the extent to which such Person is entitled to participate in such payment or distribution
and any other facts pertinent to the right of such Person under this Article 13, and, if such
evidence is not furnished, the Trustee may defer any payment to such Person pending judicial
determination as to the right of such Person to receive such payment or distribution.

     Section 13.03 Payment Prior To Dissolution Or Default. Nothing contained in this
Article or elsewhere in this Indenture, or in any of the Subordinated Securities, shall prevent (a)
the Company, at any time except under the conditions described in Section 13.02 or during the
pendency of any dissolution or winding up or total or partial liquidation or reorganization
proceedings therein referred to, from making payments at any time of principal of (or premium, if
any) or interest on Subordinated Securities or from depositing with the Trustee or any Paying Agent
moneys for such payments, or (b) the application by the Trustee or any Paying Agent of any moneys
deposited with it under this Indenture to the payment of or on account of the principal of (or
premium, if any) or interest on Subordinated Securities to the Holders entitled thereto if such
payment would not have been prohibited by the provisions of Section 13.02 on the day such moneys
were so deposited.

     Notwithstanding the provisions of Section 13.01 or any other provision of this Indenture, the
Trustee and any Paying Agent shall not be charged with knowledge of the existence of any Senior
Indebtedness, or of the occurrence of any default with respect to Senior Indebtedness of the
character described in Section 13.02, or of any other facts which would prohibit the making of any
payment of moneys to or by the Trustee or such Paying Agent, unless and until the Trustee shall
have received, no later than three Business Days prior to such payment, written notice thereof from
the Company or from a holder of such Senior Indebtedness and the Trustee shall not be affected by
any such notice which may be received by it on or after such third Business Day.

     Section 13.04 Securityholders Authorize Trustee To Effectuate Subordination of
Securities. Each Holder of Subordinated Securities by his or her acceptance thereof authorizes
and expressly directs the Trustee on his or her behalf to take such action in accordance with the
terms of this Indenture as may be necessary or appropriate to effectuate the subordination
provisions contained in this Article 13 and to protect the rights of the Holders of Subordinated
Securities pursuant to this Indenture, and appoints the Trustee his or her attorney-in-fact for
such purpose.

     Section 13.05 Right Of Trustee To Hold Senior Indebtedness. The Trustee shall be
entitled to all of the rights set forth in this Article 13 in respect of any Senior Indebtedness at
any time held by it to the same extent as any other holder of Senior Indebtedness, and nothing in
this Indenture shall be construed to deprive the Trustee of any of its rights as such holder.

     Section 13.06 Article 13 Not To Prevent Events Of Default. The failure to make a
payment on account of principal of, premium, if any, or interest on the Subordinated Securities by
reason of any provision of this Article 13 shall not be construed as preventing the occurrence of
an Event of Default under Section 6.01 or an event which with the giving of notice or lapse of
time, or both, would become an Event of Default or in any way prevent the Holders of

60

 

Subordinated Securities from exercising any right hereunder other than the right to receive
payment on the Subordinated Securities.

     Section 13.07 No Fiduciary Duty Of Trustee To Holders Of Senior Indebtedness. The
Trustee shall not be deemed to owe any fiduciary duty to the holders of Senior Indebtedness, and
shall not be liable to any such holders (other than for its willful misconduct, bad faith or
negligence) if it shall in good faith mistakenly pay over or distribute to the Holders of
Subordinated Securities or the Company or any other Person, cash, property or securities to which
any holders of Senior Indebtedness shall be entitled by virtue of this Article 13 or otherwise.
Nothing in this Section 13.07 shall affect the obligation of any other such Person to hold such
payment for the benefit of, and to pay such payment over to, the holders of Senior Indebtedness or
their representative.

LUMINEX CORPORATION

[SINKING FUND][NON-SINKING FUND] NOTE DUE

     LUMINEX CORPORATION, a corporation duly organized and existing under the laws of the State of
Delaware (herein called the “Company”, which term includes any successor corporation under the
Indenture referred to on the reverse hereof), for value received, hereby promises to pay to                      or
registered assigns, the principal sum of            on                , 20     , and to pay interest on said principal
sum semi-annually on            and            of each year, commencing,                      20      , at the rate of ___% per
annum from                , 20     , or from the most recent date in respect of which interest has been paid or
duly provided for, until payment of the principal sum has been made or duly provided for. The
interest so payable and punctually paid or duly provided for on any Interest Payment Date will, as
provided in the Indenture, be paid to the Person in whose name this Note (or one or more
Predecessor Securities) is registered at the close of business on the Record Date for such Interest
Payment Date, which shall be the fifteenth day (whether or not a New York Business Day) next
preceding such Interest Payment Date. Any such interest that is payable but is not so punctually
paid or duly provided for shall forthwith cease to be payable to the registered Holder on such
Record Date and may either be paid to the Person in whose name this Note (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, notice whereof shall be given to
Holders of Notes not earlier than 10 days prior to such Special Record Date, or may be paid at any

manner of payment shall be deemed practical by the Trustee, all as more fully provided in the
Indenture.

     Payment of the principal of and interest on this Note will be made at the Place of Payment in

Company by checks mailed to the addresses of the Persons entitled thereto as such addresses shall
appear in the Security Register.

     Reference is made to the further provisions of this Note set forth on the reverse hereof,
which shall have the same effect as though fully set forth at this place. Unless the certificate
of authentication hereon has been executed by or on behalf of the Trustee by manual signature, this

LUMINEX CORPORATION

NOTE DUE

     This Note is one of a duly authorized issue of debentures, notes or other evidences of
indebtedness of the Company (herein called the “Securities”), issued and to be issued in one or
more series under an Indenture, dated as of                                , 2008 (herein called
the “Indenture”), between the Company and The Bank of New York Trust Company, N.A., as Trustee
(herein called the “Trustee”, which term includes any successor trustee under the Indenture), to
which Indenture and all indentures supplemental thereto reference is hereby made for a statement of
the respective rights thereunder of the Company, the Trustee, and the Holders of the Securities,
the terms upon which the Securities are, and are to be, authenticated and delivered, and the
definition of capitalized terms used herein and not otherwise defined herein. The Securities may
be issued in one or more series, which different series may be issued in various aggregate
principal amounts, may be denominated in different currencies, may mature at different times, may
bear interest (if any) at different rates (which rates may be fixed or variable), may be subject to
different redemption provisions (if any), may be subject to different sinking, purchase, or
analogous funds (if any), may be subject to different covenants and Events of Default, and may
otherwise vary as provided in the Indenture. This Note is one of a series of Securities of the
Company designated as set forth on the face hereof (herein called the “Notes”), limited in
aggregate principal amount to                                .

     [The Notes may not be redeemed by the Company prior to maturity except pursuant to the sinking
fund.]

     [The Notes are subject to redemption upon not less than 30 nor more than 60 days’ notice by
mail (1) on                                 in any year commencing with the year 20  and
ending with the year 20           through operation of the sinking fund for the series at a
Redemption Price equal to 100% of the principal amount thereof, and (2) at any time, in whole or in
part, at the election of the Company, at the following Redemption Prices (expressed as percentages
of the principal amount):

     If redeemed during the 12-month period beginning each of the years indicated:

							
	 	 	 	 	 	 	 
	Years
	 	Price
	 	Years
	 	Redemption Price
	 	 	 	 	 	 	 
	 	 	 	 	 	 	 

and thereafter at a Redemption Price equal to           % of the principal amount, together in the case of
any such redemption (whether through operation of the sinking fund or otherwise) with accrued
interest to the Redemption Date, but interest installments that are due on or prior to such
Redemption Date will be payable to the Holders of record of such Notes or one or more Predecessor
Securities at the close of business on the applicable Record Dates referred to on the face hereof.]

4

 

     [Notwithstanding the foregoing, the Company may not, prior to                 , 20          , redeem any Notes as contemplated by clause (2) of the preceding paragraph as a part of, or in
anticipation of, any refunding operation by the application, directly or indirectly, of moneys
borrowed having an interest cost to the Company (calculated in accordance with generally accepted
accounting practices) of less than           % per annum.]

     [The sinking fund provides for the redemption on                                 in each year
beginning with the year                                 and ending with the year                                
of not less than                                 in principal amount of Notes (“mandatory sinking fund”).
At its option, the Company may make an additional sinking fund payment on or before the due date of
any mandatory sinking fund payment to redeem up to an additional principal amount of Notes on any
such date. The option to make such sinking fund payments in addition to the mandatory sinking fund
is not cumulative and to the extent not availed of in any year will terminate.

     At its option, the Company may credit against any mandatory sinking fund payment the principal
amount of Notes acquired or redeemed by it (other than with mandatory sinking fund payments) and
not previously credited.]

     In the event of redemption of this Note in part only, a new Note or Notes for the unredeemed
portion hereof will be issued in the name of the Holder hereof upon cancellation hereof.

     The Indenture permits, with certain exceptions as therein provided, the amendment thereof and
the modification of the rights and obligations of the Company and the rights of the Holders of the
Securities of each series under the Indenture at any time by the Company and the Trustee with the
consent of the Holders of a majority in aggregate principal amount of the Securities at the time
Outstanding of each series to be affected by such amendment or modification. The Indenture also
contains provisions permitting the Holders of a majority in aggregate principal amount of the
Securities of each series at the time Outstanding, on behalf of the Holders of Securities of such
series, to waive compliance by the Company with certain provisions of the Indenture and certain
past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder
of this Note shall be conclusive and binding upon such Holder and upon all future Holders of this
Note and of any Note issued upon 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 Note.

     The Indenture contains provisions setting forth certain conditions to the institution of
proceedings by Holders of Securities with respect to the Indenture or for any remedy under the
Indenture.

     If an Event of Default with respect to the Notes shall occur and be continuing, the principal
amount hereof may be declared due and payable or may be otherwise accelerated in the manner and
with the effect provided in the Indenture.

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

5

 

     As provided in the Indenture and subject to certain limitations therein set forth, the
transfer of this Note is registerable in the Security Register, upon surrender of this Note for
registration of transfer at the office or agency of the Company in any Place of Payment duly
endorsed, 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 Notes, of authorized denominations and for the same
aggregate principal amount, will be issued to the designated transferee or transferees.

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

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

     Prior to the presentment of this Note for registration of transfer, the Company, the Trustee,

301, of the principal amount of such Security (or, in the case of a Security described in Clause

the Corporation or any other obligor upon the Securities or any Affiliate of the Corporation or of
such other obligor, whether of record or beneficially, shall be disregarded and deemed not to be
Outstanding, except that, in determining whether the Trustee shall be protected in relying upon any
such request, demand, authorization, direction, notice, consent, waiver or other action, only
Securities which 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

Securities and that the pledgee is not the Corporation or any other obligor upon the Securities or

     Upon any application or request by the Corporation to the Trustee to take any action under any
provision of this Indenture, the Corporation shall furnish to the Trustee such certificates and
opinions as may be required under the Trust Indenture Act. Each such certificate or opinion shall
be given in the form of an Officers’ Certificate, if to be given by an officer of the Corporation,
or an Opinion of Counsel, if to be given by counsel, and shall comply with the requirements of the
Trust Indenture Act and any other requirements set forth in this Indenture.

the opinion of, only one such Person, or that they be so certified or covered by only one document,
but one such Person may certify or give an opinion with respect to some matters and one or more
other such Persons as to other matters, and any such Person may certify or give an opinion as to
such matters in one or several documents.

     Any certificate or opinion of an officer of the Corporation may be based, insofar as it
relates to legal matters, upon a certificate or opinion of, or representations by, counsel, unless
such officer knows, or in the exercise of reasonable care should know, that the certificate or
opinion or representations with respect to the matters upon which his certificate or opinion is
based are erroneous. Any such certificate or opinion of counsel may be based, insofar as it relates
to factual matters, upon a certificate or opinion of, or representations by, an officer or officers
of the Corporation stating that the information with respect to such factual matters is in the
possession of the Corporation, unless such counsel knows, or in the exercise of reasonable care
should know, that the certificate or opinion or representations with respect to such matters are
erroneous.

     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.

     Whenever, subsequent to the receipt by the Trustee of any Board Resolution, Officers’
Certificate, Opinion of Counsel or other document or instrument, a clerical, typographical or other
inadvertent or unintentional error or omission shall be discovered therein, a new document or
instrument may be substituted therefor in corrected form with the same force and effect as if
originally filed in the corrected form and, irrespective of the date or dates of the actual
execution and/or delivery thereof, such substitute document or instrument shall be deemed to have
been executed and/or delivered as of the date or dates required with respect to the document or
instrument for which it is substituted. Anything in this Indenture to the contrary notwithstanding,
if any such corrective document or instrument indicates that action has been taken by or at the
request of the Corporation which could not have been taken had the original document or instrument
not contained such error or omission, the action so taken shall not be invalidated or otherwise
rendered ineffective but shall be and remain in full force and effect, except to the extent that
such action was a result of willful misconduct or bad faith. Without limiting the generality of the
foregoing, any Securities issued under the authority of such defective document or instrument shall
nevertheless be the valid obligations of the Corporation entitled to the benefits of this Indenture
equally and ratably with all other Outstanding Securities, except as aforesaid.

     Section 104. Acts of Holders; Record Dates

     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 the Trustee
and, where it is hereby expressly required, to the Corporation. Such instrument or instruments (and
the action embodied therein and evidenced thereby) are herein sometimes referred to as the “Act” of
the Holders signing such instrument or instruments. Proof of execution of any such instrument or of
a
writing appointing any such agent shall be sufficient for any purpose of this Indenture and
(subject to Section 601) conclusive in favor of the Trustee and the Corporation, if made in the
manner provided in this Section.

6

 

     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.

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

     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
Corporation in reliance thereon, whether or not notation of such action is made upon such Security.

     The Corporation 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
Corporation 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 or revoke 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 Corporation 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 Corporation, 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 106.

     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 502, (iii) any request to
institute proceedings referred to in Section 507(2) or (iv) any direction referred to in Section
512, 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 or to
revoke the same, 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 Corporation’s expense, shall cause notice of such
record date, the proposed action by Holders and the applicable Expiration Date to be sent to the
Corporation in writing and to each Holder of Securities of the relevant series in the manner set
forth in Section 106.

     With respect to any record date set pursuant to this Section, the party hereto which sets such
record dates may designate any day as the “Expiration Date” and from time to time may change the
Expiration Date to any earlier or later day; provided that no such change shall be effective unless
notice of the proposed new Expiration Date is

7

 

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 106, on or
prior to the existing Expiration Date. If an Expiration Date is not designated with respect to any
record date set pursuant to this Section, the party hereto which set such record date shall be
deemed to have initially designated the 180th day after such record date as the Expiration Date
with respect thereto, subject to its right to change the Expiration Date as provided in this
paragraph. Notwithstanding the foregoing, no Expiration Date shall be later than the 180th day
after the applicable record date.

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

     Section 105. Notices, Etc., to Trustee and Corporation

     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 Corporation shall be sufficient for every
purpose hereunder if made, given, furnished or filed in writing to or with the Trustee at
its Corporate Trust Office, Attention: Corporate Finance, or

     (2) the Corporation 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 Corporation addressed to it at the address of its
principal office specified in the first paragraph of this instrument, attention: Treasurer,
or at any other address previously furnished in writing to the Trustee by the Corporation.

     Section 106. Notice to Holders; Waiver

     Where this Indenture provides for notice to Holders of any event, such notice shall be
sufficiently given (unless otherwise herein expressly provided) if in writing and mailed,
first-class postage prepaid, to each Holder affected by such event, at 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 107. Conflict with Trust Indenture Act

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

     Section 108. Effect of Headings and Table of Contents

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

     Section 109. Successors and Assigns

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

     Section 110. Separability Clause

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

     Section 111. Benefits of Indenture

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

     Section 112. Governing Law; Waiver of Trial by Jury

     This Indenture and the Securities shall be governed by and construed in accordance with the
laws of the State of New York, without regard to conflicts of laws principles thereof.

     Each of the Corporation and the Trustee irrevocably waives, to the fullest extent permitted by
applicable law, any and all right to trial by jury in any legal proceeding arising out of or
relating to this Indenture or the transactions contemplated hereby.

     Section 113. 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.

ARTICLE TWO

overdue shall bear interest at the rate of       % per annum (to the extent that the payment of such
interest shall be legally enforceable), from the dates such amounts are due until they are paid or
made available for payment, and such interest shall be payable on demand]. The interest so payable,
and punctually paid or duly provided for, on any Interest Payment Date will, as provided in such

inconsistent with the requirements of any securities exchange on which the Securities of this

Security shall not bear interest except in the case of a default in payment of principal upon
acceleration, upon redemption or at Stated Maturity and in such case the overdue principal and any
overdue premium shall bear interest at the rate of       % per annum (to the extent that the payment
of such interest shall be legally enforceable), from the dates such amounts are due until they are
paid or made available for payment. Interest on any overdue principal or premium shall be payable
on demand. Any such interest on overdue principal or premium which is not paid on demand shall bear
interest at the rate of      % per annum (to the extent that the payment of such interest on interest
shall be legally enforceable), from the date of such demand until the amount so demanded is paid or
made available for payment. Interest on any overdue interest shall be payable on demand.]

     Payment of the principal of (and premium, if any) and [if applicable, insert—any such]
interest on this Security will be made at the office or agency of the Corporation maintained for

the Trustee at least sixteen (16) days prior to the date for payment by the Person entitled
thereto].

and thereafter at a Redemption Price equal to       % of the principal amount, together in the case of
any such redemption (whether through operation of the sinking fund or otherwise) with accrued
interest to the Redemption Date, but interest installments whose Stated Maturity is on or prior to
such Redemption Date will be payable to the Holders of such Securities, or one or more Predecessor
Securities, of record at the close of business on the relevant Record Dates referred to on the face
hereof, all as provided in the Indenture.]

     [If applicable, insert—Notwithstanding the foregoing, the Corporation may not, prior to      
        , redeem any Securities of this series as contemplated by [if applicable, insert—Clause (2) of]
the preceding paragraph as a part of, or in anticipation of, any refunding operation by the
application, directly or indirectly, of moneys borrowed having an interest cost to the Corporation
(calculated in accordance with generally accepted financial practice) of less than      % per annum.]

     [If applicable, insert—The sinking fund for this series provides for the redemption on      
in each year beginning with the year       and ending with the year       of [if applicable,
insert—not less than $       (“mandatory sinking fund”) and not more than] $       aggregate
principal amount of Securities of this series. Securities of this series acquired or redeemed by
the Corporation otherwise than through [if applicable, insert—mandatory] sinking fund payments may
be credited against subsequent [if applicable, insert—mandatory] sinking fund payments otherwise
required to be made [if applicable, insert—, in the inverse order in which they become due].]

     [If the Security is subject to redemption of any kind, insert—In the event of redemption of
this Security in part only, a new Security or Securities of this series and of like tenor for the
unredeemed portion hereof will be issued in the name of the Holder hereof upon the cancellation
hereof.]

     [If applicable, insert—The Indenture contains provisions for defeasance at any time of [the
entire indebtedness of this Security] [or] [certain restrictive covenants and Events of Default
with respect to this Security] [, in each case] upon compliance with certain conditions set forth
in the Indenture.]

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

     [If the Security is an Original Issue Discount Security, insert—If an Event of Default with
respect to Securities of this series shall occur and be continuing, an amount of principal of the
Securities of this series may be declared due and payable in the manner and with the effect
provided in the Indenture. Such amount shall be equal to [insert formula for determining the
amount]. Upon payment of (i) the amount of principal so declared due and payable and (ii) interest
on any overdue principal, premium and interest (in each case to the extent that the payment of such
interest shall be legally enforceable), all of the Corporation’s obligations in respect of the
payment of the principal of and premium and interest, if any, on the Securities of this series
shall terminate.]

     The Indenture permits, with certain exceptions as therein provided, the amendment thereof and
the modification of the rights and obligations of the Corporation and the rights of the Holders of
the Securities of all series affected under the Indenture at any time by the Corporation and the
Trustee with the consent of the Holders of a majority in principal amount of the Securities of all
series at the time Outstanding affected thereby (voting as one class). The Indenture contains
provisions permitting the Holders of not less than a majority in principal amount of the Securities
of all series at the time Outstanding with respect to which a default under the Indenture shall
have

12

 

occurred and be continuing (voting as one class), on behalf of the Holders of the Securities
of all such series, to waive, with certain exceptions, such past default with respect to all such
series and its consequences. The Indenture also permits the Holders of not less than a majority in
principal amount of the Securities of each series at the time Outstanding, on behalf of the Holders
of all Securities of such series, to waive compliance by the Corporation with certain provisions of
the Indenture. 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 therefor 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 with respect to the Indenture or for the
appointment of a receiver or trustee or for any other remedy thereunder unless such Holder shall
have previously given the Trustee written notice of a continuing Event of Default with respect to
the Securities of this series, the Holders of not less than a majority in principal amount of the
Securities of this series at the time Outstanding shall have made written request to the Trustee to
institute proceedings in respect of such Event of Default as Trustee and offered the Trustee
reasonable indemnity, and the Trustee shall not have received from the Holders of a majority in
principal amount of Securities of this series at the time Outstanding a direction inconsistent with
such request, and shall have failed to institute any such proceeding, for 60 days after receipt of
such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted
by the Holder of this Security for the enforcement of any payment of principal hereof or any
premium or interest hereon 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 Corporation, which is absolute and unconditional, to
pay the principal of and any premium and interest on this Security at the times, place and rate,
and in the coin or currency, herein prescribed.

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

     The Securities of this series are issuable only in registered form without coupons in
denominations of $1,000 and any integral multiple thereof. As provided in the Indenture and subject
to certain limitations therein set forth, Securities of this series are exchangeable for a like
aggregate principal amount of Securities of this series and of like tenor of a different authorized
denomination, as requested by the Holder surrendering the same.

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

     Prior to due presentment of this Security for registration of transfer, the Corporation, the
Trustee and any agent of the Corporation or the Trustee may treat the Person in whose name this
Security is registered as the owner hereof for all purposes, whether or not this Security be
overdue, and neither the Corporation, the Trustee nor any such agent shall be affected by notice to
the contrary.

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

     Section 204. Form of Legend for Global Securities

     Unless otherwise specified as contemplated by Section 301 for the Securities evidenced
thereby, every Global Security authenticated and delivered hereunder shall bear a legend in
substantially the following form:

     (19) any addition to or change in the covenants set forth in Article Ten which applies
to Securities of the series;

     (20) whether such Securities are Subordinated Securities and if so, the provisions for

     (21) any other terms of the series.

     All Securities of any one series shall be substantially identical except as to denomination
and except as may otherwise be provided in or pursuant to the Board Resolution referred to above
and (subject to Section 303) set forth, or determined in the manner provided, in the Officers’
Certificate referred to above or in any such indenture supplemental hereto.

     If any of the terms of the series are established by action taken pursuant to a Board
Resolution, a copy of an appropriate record of such action shall be certified by the Secretary or
an Assistant Secretary of the Corporation and delivered to the Trustee at or prior to the delivery of the Officers’ Certificate setting forth the
terms or the manner of determining the terms of the series.

     With respect to Securities of a series offered in a Periodic Offering, the Board Resolution
(or action taken pursuant thereto), Officers’ Certificate or supplemental indenture referred to
above may provide general terms or parameters for Securities of such series and provide either that
the specific terms of particular Securities of such series shall be specified in a Company Order or
that such terms shall be determined by the Corporation in accordance with other procedures
specified in a Company Order as contemplated by the third paragraph of Section 303.

     Notwithstanding Section 301(2) herein and unless otherwise expressly provided with respect to
a series of Securities, the aggregate principal amount of a series of Securities may be increased
and additional Securities of such series may be issued up to the maximum aggregate principal amount
authorized with respect to such series as increased.

     Section 302. Denominations.

     The Securities of each series shall be issuable only in fully registered form without coupons
and only in such denominations as shall be specified as contemplated by Section 301. In the absence
of any such specified denomination with respect to the Securities of any series, the Securities of
such series shall be issuable in denominations of $1,000 and any integral multiple thereof.

     Section 303. Execution, Authentication, Delivery and Dating

     The Securities shall be executed on behalf of the Corporation by its Chairman of the Board,
its President, one of its Vice Presidents, its Treasurer or one of its Assistant Treasurers. 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 Corporation shall bind the Corporation, 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.

16

 

     At any time and from time to time after the execution and delivery of this Indenture, the
Corporation may deliver Securities of any series executed by the Corporation 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, provided, however, that in the case of Securities offered in a Periodic Offering,
the Trustee shall authenticate and deliver such Securities from time to time in accordance with
such other procedures (including, without limitation, the receipt by the Trustee of oral or
electronic instructions from the Corporation or its duly authorized agents, promptly confirmed in
writing) acceptable to the Trustee as may be specified by or pursuant to a Company Order delivered
to the Trustee prior to the time of the first authentication of Securities of such series. 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 201 and 301, 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 601) 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 201, that such form has been established in conformity
with the provisions of this Indenture;

     (2) if the terms of such Securities have been, or in the case of Securities of a
series offered in a Periodic Offering, will be, established by or pursuant to Board
Resolution as permitted by Section 301, that such terms have been, or in the case of
Securities of a series offered in a Periodic Offering, will be, established in conformity
with the provisions of this Indenture, subject, in the case of Securities of a series
offered in a Periodic Offering, to any conditions specified in such Opinion of Counsel; and

     (3) that such Securities, when authenticated and delivered by the Trustee and issued
by the Corporation in the manner and subject to any conditions specified in such Opinion of
Counsel, will constitute valid and legally binding obligations of the Corporation
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.

     If such form or terms have been so established, the Trustee shall not be required to
authenticate such Securities if the issue of such Securities pursuant to this Indenture will affect
the Trustee’s own rights, duties or immunities under the Securities and this Indenture or otherwise
in a manner which is not reasonably acceptable to the Trustee.

     Notwithstanding the provisions of Section 301 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 301 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.

     With respect to Securities of a series offered in a Periodic Offering, the Trustee may rely,
as to the authorization by the Corporation of any of such Securities, the form and terms thereof
and the legality, validity, binding effect and enforceability thereof, upon the Opinion of Counsel
and the other documents delivered pursuant
to Sections 201 and 301 and this Section, as applicable, in connection with the first
authentication of Securities of such series.

     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 of an authorized
signatory, and such certificate upon any Security shall be conclusive evidence, and the only
evidence, that such Security has been duly authenticated and delivered hereunder. Notwithstanding
the foregoing, if any Security shall have been authenticated and delivered hereunder but never
issued and sold by the Corporation, and the Corporation shall deliver such Security to the Trustee
for

17

 

cancellation as provided in Section 309, for all purposes of this Indenture such Security shall
be deemed never to have been authenticated and delivered hereunder and shall never be entitled to
the benefits of this Indenture.

     Section 304. Temporary Securities

     Pending the preparation of definitive Securities of any series, the Corporation 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 Corporation 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 Corporation 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 Corporation shall execute and the Trustee shall authenticate and deliver in exchange therefore
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.

     Section 305. Registration; Registration of Transfer and Exchange

     The Corporation shall cause to be kept at the Corporate Trust Office of the Trustee a register
(the register maintained in such office or in any other office or agency of the Corporation in a
Place of Payment being herein sometimes referred to as the “Security Register”) in which, subject
to such reasonable regulations as it may prescribe, the Corporation 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 Corporation in a Place of Payment for that series, the Corporation 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 Corporation 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 Corporation, 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 Corporation or the Trustee) be duly endorsed, or be accompanied by a written
instrument of transfer in form satisfactory to the Corporation 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 Corporation 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 304, 906 or 1106 not involving any transfer.

18

 

     If the Securities of any series (or of any series and specified tenor) are to be redeemed, the
Corporation 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 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.

     The provisions of Clauses (1), (2), (3) and (4) below shall apply only to Global Securities:

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

     (2) Notwithstanding any other provision in this Indenture, no Global Security may be
exchanged in whole or in part for Securities registered, and no transfer of a Global
Security in whole or in part may be registered, in the name of any Person other than the
Depositary for such Global Security or a nominee thereof unless (A) such Depositary has
notified the Corporation that it is unwilling or unable to continue as Depositary for such
Global Security and a successor Depositary has not been appointed by the Corporation within
90 days of receipt by the Corporation of such notification, (B) at any time the Depositary
ceases to be a clearing agency registered under the Exchange Act at a time when the
Depositary is required to be so registered to act as such Depositary and no successor
Depositary shall have been appointed by the Corporation within 90 days after it became aware
of such cessation, or (C) there shall exist such circumstances, if any, in addition to or in
lieu of the foregoing as have been specified for this purpose as contemplated by Section
301. Notwithstanding the foregoing, the Corporation may at any time in its sole discretion
and subject to the procedures of the Depositary determine that Securities issued in the form
of a Global Security shall no longer be represented in whole or in part by such Global
Security, and the Trustee, upon receipt of a Company Order therefor, shall authenticate and
deliver definitive Securities in exchange in whole or in part for such Global Security.

     (3) Subject to Clause (2) above, any exchange or transfer of a Global Security for
other Securities may be made in whole or in part, and all Securities issued in exchange for
or upon transfer of a Global Security or any portion thereof shall be registered in such
names as the Depositary for such Global Security shall direct.

     (4) Every Security authenticated and delivered upon registration of transfer of, or in
exchange for or in lieu of, a Global Security or any portion thereof, whether pursuant to
this Section, Section 304, 306, 906 or 1106 or otherwise, shall be authenticated and
delivered in the form of, and shall be, a Global Security, unless such Security is
registered in the name of a Person other than the Depositary for such Global Security or a
nominee thereof.

     Section 306. Mutilated, Destroyed, Lost and Stolen Securities

     If any mutilated Security is surrendered to the Trustee, the Corporation 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 Corporation 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 Corporation or the Trustee that such Security has been acquired by a
bona fide purchaser, the Corporation 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 Corporation in its discretion may, instead of issuing a new Security,
pay such Security.

19

 

     Upon the issuance of any new Security under this Section, the Corporation 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 Corporation, 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 307. Payment of Interest; Interest Rights Preserved

     Except as otherwise provided as contemplated by Section 301 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.

     Except as otherwise provided as contemplated by Section 301 with respect to any series of
Securities, 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 Corporation, at its election in
each case, as provided in Clause (1) or (2) below:

     (1) The Corporation 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 Corporation 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
Corporation 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 Corporation of such Special Record Date and, in the name and at
the expense of the Corporation, 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 106, 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 Corporation 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, if any, on which such Securities may be listed, and upon such notice as
may be required by such exchange, if, after notice given by the Corporation to the Trustee
of the proposed payment pursuant to this Clause, such manner of payment shall be deemed
practicable by the Trustee.

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

     Section 308. Persons Deemed Owners

     Prior to due presentment of a Security for registration of transfer, the Corporation, the
Trustee and any agent of the Corporation 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 307) any interest on such Security and for all
other purposes whatsoever, whether or not such Security be overdue, and neither the Corporation,
the Trustee nor any agent of the Corporation or the Trustee shall be affected by notice to the
contrary.

     Section 309. 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 Corporation may at
any time deliver to the Trustee for cancellation any Securities previously authenticated and
delivered hereunder which the Corporation 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 Corporation has not issued and sold, and
all Securities so delivered shall be promptly cancelled by the Trustee. No Securities shall be
authenticated in lieu of or in exchange for any Securities cancelled as provided in this Section,
except as expressly permitted by this Indenture. All cancelled Securities held by the Trustee shall
be disposed of as directed by a Company Order; provided, however, that the Trustee shall not be
required to destroy such cancelled Securities.

     Section 310. Computation of Interest

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

     Section 311. CUSIP Numbers

     The Corporation 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.

ARTICLE FOUR

Satisfaction and Discharge

     Section 401. Satisfaction and Discharge of Indenture

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

          (1) either

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

21

 

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

     (i) have become due and payable, or

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

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

and the Corporation, in the case of (i), (ii) or (iii) above, has deposited or
caused to be deposited with the Trustee as trust funds in trust for the purpose (I)
money in an amount, (II) Government Obligations (as defined in Section 1304) which
through the scheduled payment of principal and interest in respect thereof in
accordance with their terms will provide, not later than the due date of any
payment, money in an amount, or (III) a combination thereof, sufficient, in the case
of (II) or (III), 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 to pay and
discharge, the entire indebtedness on such Securities not theretofore delivered to
the Trustee for cancellation, for principal and any premium and interest to the date
of such deposit (in the case of Securities which have become due and payable) or to
the Stated Maturity or Redemption Date, as the case may be;

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

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

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

     Section 402. Application of Trust Money

     Subject to the provisions of the last paragraph of Section 1003, all money deposited with the
Trustee pursuant to Section 401 shall be held in trust and applied by it, in accordance with the
provisions of the Securities and this Indenture, to the payment, either directly or through any
Paying Agent (including the Corporation 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. Moneys held pursuant to this Section for
the benefit of the Holders of Subordinated Securities shall not be subject to the subordination
provisions established with respect to such Securities pursuant to Section 301(20).

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

     Anything in this Article to the contrary notwithstanding, the Trustee shall deliver or pay to
the Corporation from time to time upon Company Request any money or Government Obligations held by
it as provided in Section 401 which, in the opinion of a nationally recognized firm of independent
public accountants expressed in a written certification thereof delivered to the Trustee (in case
Government Obligations are held by the Trustee as provided in Section 401), are in excess of the
amount thereof which would then be required to be deposited to effect the

22

 

satisfaction and
discharge of this Indenture.

ARTICLE FIVE

Remedies

     Section 501. Events of Default

     “Event of Default,” wherever used herein with respect to Securities of any series, means any
one of the following events (whatever the reason for such Event of Default and whether it shall be
voluntary or involuntary or be effected by operation of law or pursuant to any judgment, decree or
order of any court or any order, rule or regulation of any administrative or governmental body),
unless it is inapplicable to a particular series or is specifically deleted or modified in the
Board Resolution (or action taken pursuant thereto), Officers’ Certificate or supplemental
indenture under which such series of Securities is issued or has been deleted or modified in an
indenture supplemental hereto:

     (1) default in the payment of any interest upon any Security of that series when it
becomes due and payable, and continuance of such default for a period of 60 days; provided,
however, that if the Corporation is permitted by the terms of the Securities of such series
to defer the payment in question, the date on which such payment is due and payable shall be
the date on which the Corporation is required to make payment following such deferral, if
such deferral has been elected pursuant to the terms of the Securities; or

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

     (3) default in the making of any sinking fund payment, when and as due by the terms of
a Security of that series, and continuance of such default for a period of 60 days; or

     (4) default in the performance, or breach, of any covenant of the Corporation in this
Indenture (other than a covenant 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 90 days after there has been given, by
registered or certified mail, to the Corporation by the Trustee or to the Corporation
and the Trustee by the Holders of at least 33% 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, unless
the Trustee, or the Trustee and the Holders of a principal amount of Securities of such
series not less than the principal amount of Securities the Holders of which gave such
notice, as the case may be, shall agree in writing to an extension of such period prior to
its expiration; provided, however, that the Trustee, or the Trustee and the Holders of such
principal amount of Securities of such series, as the case may be, shall be deemed to have
agreed to an extension of such period if corrective action is initiated by the Corporation
within such period and is being diligently pursued; or

     (5) the
entry by a court having jurisdiction in the premises of (A) a decree or order
for relief in respect of the Corporation in an involuntary case or proceeding under any
applicable federal or state bankruptcy, insolvency, reorganization or other similar law or
(B) a decree or order adjudging the Corporation a bankrupt or insolvent, or approving as
properly filed a petition seeking reorganization, arrangement, adjustment or composition of
or in respect of the Corporation under any applicable federal or state law, or appointing a
custodian, receiver, liquidator, assignee, trustee, sequestrator or other similar official
of the Corporation or of any substantial part of its property, or ordering the winding-up or
liquidation of its affairs, and the continuance of any such decree or order for relief or
any such other decree or order unstayed and in effect for a period of 90 consecutive days;
or

     (6) the
commencement by the Corporation of a voluntary case or proceeding under any
applicable

23

 

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

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

     Section 502. Acceleration of Maturity; Rescission and Annulment

     If an Event of Default 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 33% 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 Corporation (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.

     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 Event of Default giving rise to such
declaration of acceleration shall, without further act, be deemed to have been waived, and such
declaration and its consequences shall, without further act, be deemed to have been rescinded and
annulled, if

     (1) the Corporation 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

     (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 has become due solely by
such declaration of acceleration, have been cured or waived as provided in Section 513.

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

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

     The Corporation covenants that if

24

 

     (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 60 days, or

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

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

     Section 504. Trustee May File Proofs of Claim

     In case of any judicial proceeding relative to the Corporation (or any other obligor upon the
Securities), its property or its creditors, the Trustee shall be entitled and empowered, by
intervention in 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 to collect and receive any moneys or
other property payable or deliverable on any such claims and to distribute the same; and any
custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any
such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee
and, in the event that the Trustee shall consent to the making of such payments directly to the
Holders, to pay to the Trustee any amount due it for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the
Trustee under Section 607.

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

     Section 505. Trustee May Enforce Claims Without Possession of Securities

     All rights of action and claims under this Indenture or the Securities may be prosecuted and
enforced by the Trustee without the possession of any of the Securities or the production thereof
in any proceeding relating thereto, and any such proceeding instituted by the Trustee shall be
brought in its own name as trustee of an express trust, and any recovery of judgment shall, after
provision for the payment of the 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 506. 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 and the
notation thereon of the payment if only partially paid and upon surrender thereof if fully paid:

     First: To the payment of all amounts due the Trustee under Section 607;

25

 

     Second: Subject to the subordination terms established pursuant to Section 301(20), if
applicable, 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; and

     Third: To the payment of the balance, if any, to the Corporation or any other Person
or Persons legally entitled thereto.

     Section 507. Limitation on Suits

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

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

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

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

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

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

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

     Section 509. Restoration of Rights and Remedies

     If the Trustee or any Holder has instituted any proceeding to enforce any right or remedy
under this Indenture and such proceeding has been discontinued or abandoned for any reason, or has
been determined adversely to the Trustee or to such Holder, then and in every such case, subject to
any determination in such proceeding, the Corporation, 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.

26

 

     Section 510. Rights and Remedies Cumulative

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

     Section 511. Delay or Omission Not Waiver

     No delay or omission of the Trustee or of any Holder of any Securities to exercise any right
or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a
waiver of any such Event of Default or an acquiescence therein.

     Every right and remedy given by this Article or by law to the Trustee or to the Holders may be
exercised from time to time, and as often as may be deemed expedient, by the Trustee or by the
Holders, as the case may be.

     Section 512. Control by Holders.

     The Holders of a majority in 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) subject to the provisions of Section 601, the Trustee shall have the right to
decline to follow
any such direction if the Trustee in good faith shall, by a Responsible Officer or
Officers of the Trustee, determine that the proceeding so directed would involve the Trustee
in personal liability.

     Section 513. Waiver of Past Defaults

     The Holders of not less than a majority in principal amount of the Outstanding Securities of
all series with respect to which any default under the Indenture shall have occurred and be
continuing (voting as one class) may, on behalf of the Holders of all Securities of all such
series, waive such past default under the Indenture 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 the
series affected.

Upon any such waiver, such default shall cease to exist and be deemed not to have occurred, and any
Event of Default arising therefrom shall be deemed to have been cured and not to have occurred, for
every purpose of this Indenture; but no such waiver shall extend to any subsequent or other default
or impair any right consequent thereon.

     Section 514. Undertaking for Costs

     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, a court may require
any party litigant in such suit to file an undertaking to pay the costs of such suit, and may
assess costs against any such party litigant, in the

27

 

manner and to the extent provided in the Trust
Indenture Act; provided that neither this Section nor the Trust Indenture Act shall be deemed to
authorize any court to require such an undertaking or to make such an assessment in any suit
instituted by the Corporation or the Trustee.

     Section 515. Waiver of Stay or Extension Laws

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

ARTICLE SIX

The Trustee

     Section 601. Certain Duties and Responsibilities

     The duties and responsibilities of the Trustee shall be as provided by the Trust Indenture
Act. Notwithstanding the foregoing, no provision of this Indenture shall require the Trustee to
expend or risk its own funds or otherwise incur any financial liability in the performance of any
of its duties hereunder, or in the exercise of any of its rights or powers, if it shall have
reasonable grounds for believing that repayment of such funds or adequate indemnity against such
risk or liability is not reasonably assured to it. Whether or not therein expressly so provided,
every provision of this Indenture relating to the conduct or affecting the liability of or
affording protection to the Trustee shall be subject to the provisions of this Section.

     Section 602. Notice of Defaults

     If a default occurs hereunder with respect to Securities of any series, the Trustee shall give
the Holders of Securities of such series notice of such default as and to the extent provided by
the Trust Indenture Act; provided, however, that in the case of any default of the character
specified in Section 501(4) with respect to Securities of such series, no such notice to Holders
shall be given until at least 30 days after the occurrence thereof. For the purpose of this
Section, the term “default” means any event which is, or after notice or lapse of time or both
would become, an Event of Default with respect to Securities of such series.

     Section 603. Certain Rights of Trustee

     Subject to the provisions of Section 601:

     (1) the Trustee may rely and shall be protected in acting or refraining from acting
upon any resolution, certificate, statement, instrument, opinion, report, notice, request,
direction, consent, order, bond, debenture, note, other evidence of indebtedness or other
paper or document believed by it to be genuine and to have been signed or presented by the
proper party or parties;

     (2) any request or direction of the Corporation mentioned herein shall be sufficiently
evidenced by a Company Request or Company Order or as otherwise expressly provided herein,
and any resolution of the Board of Directors shall be sufficiently evidenced by a Board
Resolution;

     (3) whenever in the administration of this Indenture the Trustee shall deem it
desirable that a matter be proved or established prior to taking, suffering or omitting any
action hereunder, the Trustee (unless other evidence be herein specifically prescribed) may,
in the absence of bad faith on its part, rely upon an Officers’ Certificate;

28

 

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

     (5) the Trustee shall be under no obligation to exercise any of the rights or powers
vested in it by this Indenture at the request or direction of any of the Holders pursuant to
this Indenture, unless such Holders shall have offered to the Trustee reasonable security or
indemnity against the costs, expenses and liabilities which might be incurred by it in
compliance with such request or direction;

     (6) the Trustee shall not be bound to make any investigation into the facts or matters
stated in any resolution, certificate, statement, instrument, opinion, report, notice,
request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or
other paper or document, but the Trustee, in its discretion, may make such further inquiry
or investigation into such facts or matters as it may see fit, and, if the Trustee shall
determine to make such further inquiry or investigation, it shall be entitled, at reasonable
times previously notified to the Corporation, to examine the relevant books, records and
premises of the Corporation, personally or by agent or attorney;

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

     (8) in no event shall the Trustee be liable for special, indirect or consequential
loss or damage of any kind whatsoever (including but not limited to lost profits), even if
the Trustee has been advised of the likelihood of such loss or damage and regardless of the
form of action; and

     (9) in no event shall the Trustee be responsible or liable for any failure or delay in
the performance of its obligations under this Indenture arising out of or caused by,
directly or indirectly, forces
beyond its reasonable control, including without limitation strikes, work stoppages,
accidents, acts of war or terrorism, civil or military disturbances, nuclear or natural
catastrophes or acts of God, and interruptions, loss or malfunctions of utilities,
communications or computer (software or hardware) services.

     Section 604. Not Responsible for Recitals or Issuance of Securities

     The recitals contained herein and in the Securities, except the Trustee’s certificates of
authentication, shall be taken as the statements of the Corporation, and neither the Trustee nor
any Authenticating Agent assumes any responsibility for their correctness. The Trustee makes no
representations as to the validity or sufficiency of this Indenture or of the Securities. Neither
the Trustee nor any Authenticating Agent shall be accountable for the use or application by the
Corporation of Securities or the proceeds thereof.

     Section 605. May Hold Securities.

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

     Section 606. Money Held in Trust

     Money held by the Trustee in trust hereunder need not be segregated from other funds except to
the extent required by law. The Trustee shall be under no liability for interest on any money
received by it hereunder except as
otherwise agreed in writing with the Corporation.

     Section 607. Compensation and Reimbursement

     The Corporation agrees

29

 

     (1) to pay to the Trustee from time to time such compensation as shall be agreed to in
writing between the Corporation and the Trustee for all services rendered by it hereunder
(which compensation shall not be limited by any provision of law in regard to the
compensation of a trustee of an express trust);

     (2) except as otherwise expressly provided herein, to reimburse the Trustee upon its
request for all reasonable expenses, disbursements and advances incurred or made by the
Trustee in accordance with any provision 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 the Trustee for, and to hold it harmless against, any loss, liability
or expense 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 or
liability in connection with the exercise or performance of any of its powers or duties
hereunder.

     The Trustee shall have a lien prior to the Securities upon all property and funds held by it
hereunder for any amount owing it or any predecessor Trustee pursuant to this Section 607, except
with respect to funds held in trust for the benefit of the Holders of particular Securities.

     Without limiting any rights available to the Trustee under applicable law, when the Trustee
incurs expenses or renders services in connection with an Event of Default specified in Section
501(5) or Section 501(6), the expenses (including the reasonable charges and expenses of its
counsel) and the compensation for the services are intended to constitute expenses of
administration under any applicable federal or state bankruptcy, insolvency or other similar law.

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

     Section 608. Conflicting Interests

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

     Section 609. Corporate Trustee Required; Eligibility

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

     Section 610. Resignation and Removal; Appointment of Successor

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

     The Trustee may resign at any time with respect to the Securities of one or more series by
giving written notice thereof to the Corporation. If the instrument of acceptance by a successor
Trustee required by Section 611

30

 

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

     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 the Trustee and to the Corporation.

     If at any time:

     (1) the Trustee shall fail to comply with Section 608 after written request therefor
by the Corporation or by any Holder who has been a bona fide Holder of a Security for at
least six months, or

     (2) the Trustee shall cease to be eligible under Section 609 and shall fail to resign
after written request therefor by the Corporation 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 Corporation by a Board Resolution may remove the Trustee with
respect to all Securities, or (B) subject to Section 514, any Holder who has been a bona fide
Holder of a Security for at least six months may, on behalf of himself and all others similarly
situated, petition any court of competent jurisdiction for
the removal of the Trustee with respect to all Securities and the appointment of a successor
Trustee or Trustees.

     If the Trustee shall resign, be removed or become incapable of acting, or if a vacancy shall
occur in the office of Trustee for any cause, with respect to the Securities of one or more series,
the Corporation, 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 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 611. If, within one year after
such resignation, removal or incapability, or the occurrence of such vacancy, a successor Trustee
with respect to the Securities of any series shall be appointed by Act of the Holders of a majority
in principal amount of the Outstanding Securities of such series delivered to the Corporation and
the retiring Trustee, the successor Trustee so appointed shall, forthwith upon its acceptance of
such appointment in accordance with the applicable requirements of Section 611, become the
successor Trustee with respect to the Securities of such series and to that extent supersede the
successor Trustee appointed by the Corporation. If no successor Trustee with respect to the
Securities of any series shall have been so appointed by the Corporation or the Holders and
accepted appointment in the manner required by Section 611, any Holder who has been a bona fide
Holder of a Security 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.

     The Corporation 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 106. Each notice shall include the name of the successor Trustee with respect to the
Securities of such series and the address of its Corporate Trust Office.

     Section 611. Acceptance of Appointment by Successor

     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 Corporation
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 Corporation or the successor Trustee, such
retiring Trustee shall, upon payment of its charges, execute and deliver an instrument transferring
to such successor Trustee all the rights, powers and trusts of the retiring Trustee and shall duly
assign, transfer and

31

 

deliver to such successor Trustee all property and money held by such retiring
Trustee hereunder.

     In case of the appointment hereunder of a successor Trustee with respect to the Securities of
one or more (but not all) series, the Corporation, 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 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
Corporation or any successor Trustee, such retiring Trustee shall duly assign, transfer and deliver
to such successor Trustee all property and money held by such retiring Trustee hereunder with
respect to the Securities of that or those series to which the appointment of such successor
Trustee relates.

     Upon request of any such successor Trustee, the Corporation 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.

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

     Section 612. Merger, Conversion, Consolidation or Succession to Business

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

     Section 613. Preferential Collection of Claims Against Corporation

     If and when the Trustee shall be or become a creditor of the Corporation (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 Corporation (or any such other obligor).

     Section 614. Appointment of Authenticating Agent.

     The Trustee may appoint an Authenticating Agent or Agents acceptable to the Corporation with
respect to one or more series of Securities which shall be authorized to act on behalf of the
Trustee to authenticate Securities of such series issued upon exchange, registration of transfer or
partial redemption thereof or pursuant to Section 306, and Securities so authenticated shall be
entitled to the benefits of this Indenture and shall be valid and obligatory for all purposes as if
authenticated by the Trustee hereunder. Wherever reference is made in this Indenture to the
authentication and delivery of Securities by the Trustee or the Trustee’s certificate of
authentication, such reference

32

 

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

     An Authenticating Agent may resign at any time by giving written notice thereof to the Trustee
and to the Corporation. 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 Corporation. 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
Corporation and shall give notice of such appointment in the manner provided in Section 106 to all
Holders of Securities of the series with respect to which such Authenticating Agent will serve. Any
successor Authenticating Agent upon acceptance of its appointment hereunder shall become vested
with all the rights, powers and duties of its predecessor hereunder, with like effect as if
originally named as an Authenticating Agent. No successor Authenticating Agent shall be appointed
unless eligible under the provisions of this Section.

     The Corporation 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 Bank of New York Trust Company, N.A., as

opinion of the Trustee and the Corporation, to any such supplemental indenture may be prepared and
executed by the Corporation and authenticated and delivered by the Trustee in exchange for
Outstanding Securities of such series.

ARTICLE TEN

Covenants

shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with
the address thereof, such presentations, surrenders, notices and demands may be made or served at
the Corporate Trust Office of the Trustee, and the Corporation hereby appoints the Trustee as its
agent to receive all such presentations, surrenders, notices and demands.

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

     Section 1003. Money for Securities Payments to Be Held in Trust

     If the Corporation 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 Corporation shall have one or more Paying Agents for any series of Securities, it
will, on or prior to each due date of the principal of 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
Corporation will promptly notify the Trustee of its action or failure so to act.

     The Corporation 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 Corporation (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 Corporation 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 hereunder by the Corporation 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
Corporation 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 Corporation, 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 Corporation on Company Request, or (if then held by the Corporation)
shall be discharged from such trust; and the Holder of such Security shall thereafter, as an
unsecured general creditor, look only to the Corporation for payment thereof, and all liability of
the Trustee or such Paying Agent with respect to such trust money, and all liability of the
Corporation 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
Corporation 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, 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 Corporation.

38

 

     Section 1004. Statement by Officers as to Default.

     The Corporation will deliver to the Trustee, on or before October 15 of each calendar year or
on or before such other day in each calendar year as the Corporation and the Trustee may from time
to time agree upon, an Officers’ Certificate, stating whether or not to the best knowledge of the
signers thereof the Corporation 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 Corporation shall be in default, specifying
all such defaults and the nature and status thereof of which they may have knowledge.

     Section 1005. Waiver of Certain Covenants.

     Except as otherwise specified as contemplated by Section 301 for Securities of such series,
the Corporation 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 301(19), 901(2) or 901(7) for the benefit of the Holders of such series 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 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 Corporation and the
duties of the Trustee in respect of any such term, provision or condition shall remain in full
force and effect.

     Section 1006. Calculation of Original Issue Discount.

     The Corporation shall file with the Trustee promptly after the end of each calendar year a
written notice specifying the amount of original issue discount (including daily rates and accrual
periods) accrued on Outstanding Securities as of the end of such year.

ARTICLE ELEVEN

Redemption of Securities

     Section 1101. Applicability of Article.

     Securities of any series which are redeemable before their Stated Maturity shall be redeemable
in accordance with their terms and (except as otherwise specified as contemplated by Section 301
for such Securities) in accordance with this Article.

     Section 1102. Election to Redeem; Notice to Trustee.

     The election of the Corporation to redeem any Securities shall be evidenced by a Board
Resolution or in another manner specified as contemplated by Section 301 for such Securities. In
case of any redemption at the election of the Corporation, the Corporation shall, at least 45 days
prior to the Redemption Date fixed by the Corporation (unless a shorter notice shall be
satisfactory to the Trustee), notify the Trustee of such Redemption Date, of the principal amount
of Securities of such series to be redeemed and, if applicable, of the tenor of the Securities to
be redeemed. In the case of any redemption of Securities (a) prior to the expiration of any
restriction on such redemption provided in the terms of such Securities or elsewhere in this
Indenture, or (b) pursuant to an election of the Corporation which is subject to a condition
specified in the terms of such Securities or elsewhere in this Indenture, the Corporation shall
furnish the Trustee with an Officers’ Certificate evidencing compliance with such restriction or
condition.

     Section 1103. Selection by Trustee of Securities to Be Redeemed.

     If less than all the Securities of any series are to be redeemed (unless all the Securities of
such series and of a specified tenor are to be redeemed or unless such redemption affects only a
single Security), the particular

39

 

Securities to be redeemed shall be selected not more than 60 days
prior to the Redemption Date by the Trustee, from the Outstanding Securities of such series not
previously called for redemption, by such method as the Trustee shall deem fair and appropriate and
which may 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 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 (unless such redemption affects only a single Security), 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 Corporation in writing of the Securities selected for
redemption as aforesaid and, in the case of any Securities selected for partial redemption as
aforesaid, the principal amount
thereof to be redeemed.

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

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

     Section 1104. Notice of Redemption.

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

     All notices of redemption shall state:

     (1) the Redemption Date;

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

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

     (4) that on the Redemption Date the Redemption Price, together with accrued interest,
if any, to the Redemption Date, 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 accrued interest, if any, unless it shall have been specified as
contemplated by Section 301 with respect to such Securities that such surrender shall not be
required;

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

     (7) such other matters as the Corporation shall deem desirable or appropriate.

     Unless otherwise specified with respect to any Securities in accordance with Section 301, with
respect to any redemption of Securities at the election of the Corporation, unless, upon the giving
of notice of such redemption, Defeasance shall have been effected with respect to such Securities
pursuant to Section 1302, such notice may state

40

 

that such redemption shall be conditional upon the
receipt by the Trustee or the Paying Agent(s) for such Securities, on or prior to the date fixed
for such redemption, of money sufficient to pay the principal of and any premium and interest on
such Securities and that if such money shall not have been so received such notice shall be of no
force or effect and the Corporation shall not be required to redeem such Securities. In the event
that such notice of redemption contains such a condition and such money is not so received, the
redemption shall not be made and
within a reasonable time thereafter notice shall be given, in the manner in which the notice
of redemption was given, that such money was not so received and such redemption was not required
to be made, and the Trustee or Paying Agent(s) for the Securities otherwise to have been redeemed
shall promptly return to the Holders thereof any of such Securities which had been surrendered for
payment upon such redemption.

     Notice of redemption of Securities to be redeemed at the election of the Corporation, and any
notice of non-satisfaction of redemption as aforesaid, shall be given by the Corporation or, at the
Corporation’s request, by the Trustee in the name and at the expense of the Corporation. Subject to
the preceding paragraph, any such notice of redemption shall be irrevocable.

     Section 1105. Securities Payable on Redemption Date.

     Notice of redemption having been given as aforesaid, and the conditions, if any, set forth in
such notice having been satisfied, the Securities or portions thereof 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, in the case of an unconditional notice of redemption, the Corporation
shall default in the payment of the Redemption Price and accrued interest, if any) such Securities
or portions thereof, if interest-bearing, shall cease to bear interest. Upon surrender of any such
Security for redemption in accordance with said notice, such Security or portion thereof shall be paid by the Corporation at the Redemption Price, together with accrued interest, if any,
to the Redemption Date; provided, however, that no such surrender shall be a condition to such
payment if so specified as contemplated by Section 301 with respect to such Security, and provided
further that, unless otherwise specified as contemplated by Section 301, 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 307.

     If any Security called for redemption shall not be so paid upon surrender thereof for
redemption, the principal and any premium shall, until paid, bear interest from the Redemption Date
at the rate prescribed therefor in the Security.

     Section 1106. 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 Corporation or the Trustee so requires, due endorsement by, or a written
instrument of transfer in form satisfactory to the Corporation and the Trustee duly executed by,
the Holder thereof or his attorney duly authorized in writing), and the Corporation shall execute,
and the Trustee shall authenticate and deliver to the Holder of such Security without service
charge, a new Security or Securities of the same series and of like tenor, of any authorized
denomination as requested by such Holder, in aggregate principal amount equal to and in exchange
for the unredeemed portion of the principal of the Security so surrendered.

ARTICLE TWELVE

Sinking Funds

     Section 1201. Applicability of Article.

     The provisions of this Article shall be applicable to any sinking fund for the retirement of
Securities of any series except as otherwise specified as contemplated by Section 301 for such
Securities.

     The minimum amount of any sinking fund payment provided for by the terms of any Securities is
herein

41

 

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 1202. Each sinking fund payment shall be applied to the redemption of Securities as
provided for by the terms of such Securities.

     Section 1202. Satisfaction of Sinking Fund Payments with Securities.

     The Corporation (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 Corporation 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 1203. Redemption of Securities for Sinking Fund.

     Not less than 45 days prior to each sinking fund payment date for any Securities, the
Corporation 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 1202 and
stating the basis for such credit and that such Securities have not been previously so credited and
will also deliver to the Trustee any Securities to be so delivered. Not less than 30 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 1103 and cause notice of the
redemption thereof to be given in the name of and at the expense of the Corporation in the manner
provided in Section 1104. Such notice having been duly given, the redemption of such Securities
shall be made upon the terms and in the manner stated in Sections 1105 and 1106.

ARTICLE THIRTEEN

Defeasance and Covenant Defeasance

     Section 1301. Applicability of Article.

     Unless, pursuant to Section 301, provision is made that either or both of (a) defeasance of
any Securities or any series of Securities under Section 1302 and (b) covenant defeasance of any
Securities or any series of Securities under Section 1303 shall not apply to such Securities of a
series, then the provisions of either or both of Sections 1302 and Section 1303, as the case may
be, together with Sections 1304 and 1305, shall be applicable to the Outstanding Securities of such
series upon compliance with the conditions set forth below in this Article.

     Section 1302. Defeasance and Discharge.

     The Corporation may cause itself to be discharged from its obligations with respect to any
Securities or any series of Securities on and after the date the conditions set forth in Section
1304 are satisfied (hereinafter called “Defeasance”). For this purpose, such Defeasance means that
the Corporation 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
Corporation, 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

42

 

from the trust fund described in Section 1304 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
Corporation’s obligations with respect to such Securities under Sections 304, 305, 306, 1002 and
1003 and with respect to the Trustee under Section 607, (3) the rights, powers, trusts, duties and
immunities of the Trustee hereunder and (4) this Article. Subject to compliance with this Article,
Defeasance with respect to any Securities or any series of Securities by the Corporation is
permitted under this Section 1302 notwithstanding the prior exercise by the Corporation of its
rights under Section 1303 with respect to such Securities. Following a Defeasance, payment of such
Securities may not be accelerated because of an Event of Default.

     Section 1303. Covenant Defeasance.

     The Corporation may cause itself to be released from its obligations under any covenants
provided pursuant to Section 301(19), 901(2), 901(6) or 901(7) with respect to any Securities or
any series of Securities for the benefit of the Holders of such Securities and the occurrence of
any event specified in Section 501(4) (with respect to any such covenants provided pursuant to
Section 301(19), 901(2), 901(6) or 901(7)) or 501(7) shall be deemed not to be or result in an
Event of Default with respect to such Securities as provided in this Section, in each case on and
after the date the conditions set forth in Section 1304 are satisfied (hereinafter called “Covenant
Defeasance”). For this purpose, such Covenant Defeasance means that, with respect to such
Securities, the Corporation may omit to comply with and shall have no liability in respect of any
term, condition or limitation set forth in any such specified Section (to the extent so specified
in the case of Section 501(4)), 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 1304. Conditions to Defeasance or Covenant Defeasance.

     The following shall be the conditions to the application of Section 1302 or Section 1303 to
any Securities or any series of Securities, as the case may be:

     (1) The Corporation shall irrevocably have deposited or caused to be deposited with
the Trustee as trust funds in trust for the purpose of making the following payments,
specifically pledged as security for, and dedicated solely to, the benefit of the Holders of
such Securities, (A) money in an amount, or (B) Government Obligations which through the
scheduled payment of principal and interest in respect thereof in accordance with their
terms will provide, not later than the due date of any payment, money in an amount, or (C) a
combination thereof, sufficient, in the case of (B) or (C), 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 to pay and discharge, the principal of and any premium and interest on such
Securities on the respective Stated Maturities or on any Redemption Date established
pursuant to Clause (3) below, in accordance with the terms of this Indenture and such
Securities. As used herein, “Government Obligation” means (x) any security which is (i) a
direct obligation of the United States of America or the government which issued the foreign
currency in which such Securities are payable, for the payment of which its full faith and
credit 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 or such government which
issued the foreign currency in which such Securities are payable, the payment of which is
unconditionally guaranteed as a full faith and credit obligation by the United States of
America or such other government, 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
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 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 Government Obligation or the specific payment of
principal or interest evidenced by such depositary receipt.

     (2) No event which is, or after notice or lapse of time or both would become, an Event
of Default

43

 

with respect to such Securities or any other Securities shall have occurred and be
continuing at the time of such deposit or, with regard to any such event specified in
Sections 501(5) and (6), at any time on or prior to the 90th day after the date of such
deposit (it being understood that this condition shall not be deemed satisfied until after
such 90th day).

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

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

     Section 1305. Deposited Money and Government Obligations to Be Held in Trust; Miscellaneous Provisions.

     Subject to the provisions of the last paragraph of Section 1003, all money and Government
Obligations (including the proceeds thereof) deposited with the Trustee pursuant to Section 1304 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 Corporation 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. Moneys and Government Obligations (and the
proceeds thereof) held pursuant to this Section for the benefit of the Holders of Subordinated
Securities shall not be subject to the subordination provisions established with respect to such
Securities pursuant to Section 301(20).

     The Corporation shall pay and indemnify the Trustee against any tax, fee or other charge
imposed on or assessed against the Government Obligations deposited pursuant to Section 1304 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 Corporation from time to time upon Company Request any money or Government Obligations held by
it as provided in Section 1304 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.

ARTICLE FOURTEEN

Immunity of Incorporators, Stockholders, Officers and Directors

     Section 1401. Indenture and Securities Solely Corporate Obligations.

     No recourse for the payment of the principal of or any premium or interest on any Security, or
for any claim based thereon or otherwise in respect thereof, and no recourse under or upon any
obligation, covenant or agreement of the Corporation in this Indenture or in any supplemental
indenture, or in any Security, or because of the creation of any indebtedness represented thereby,
shall be had against any incorporator, stockholder, officer or director, as such, past, present or
future, of the Corporation or of any successor corporation, either directly or through the
Corporation or any successor corporation, whether by virtue of any constitution, statute or rule of
law, or by the enforcement of any assessment or penalty or otherwise; it being expressly understood
that all such liability is hereby expressly waived and released as a condition of, and as a
consideration for, the execution of this Indenture
and the issue of the Securities.

44

 

ARTICLE FIFTEEN

Subordination of Subordinated Securities

     Section 1501. Agreement to Subordinate.

     The Corporation covenants and agrees, and each Holder of any Subordinated Security issued
hereunder by his acceptance thereof, whether upon original issue or upon transfer or assignment,
likewise covenants and agrees, that the principal of (and premium, if any) and interest on each and
all of the Subordinated Securities issued hereunder are hereby expressly subordinated, to the
extent and in the manner hereinafter set forth, in right of payment to the prior payment in full of
all Senior Indebtedness.

     Section 1502. Payment on Dissolution, Liquidation or Reorganization; Default on Senior
Indebtedness.

     Upon any payment or distribution of assets or securities of the Corporation of any kind or
character, whether in cash, property or securities, upon any dissolution or winding up or total or
partial liquidation or reorganization of the Corporation, whether voluntary or involuntary or in
bankruptcy, insolvency, receivership or other similar proceedings, or upon any assignment for the
benefit of creditors or any other marshalling of the assets and liabilities of the Corporation or
otherwise, all principal of (and premium, if any) and interest then due upon all Senior
Indebtedness shall first be paid in full, or payment thereof provided for in money or money’s
worth, before the Holders of the Subordinated Securities or the Trustee on their behalf shall be
entitled to receive any assets or securities (other than shares of stock of the Corporation as
reorganized or readjusted or securities of the Corporation or any other corporation provided for by
a plan of reorganization or readjustment, junior to, or the payment of which is subordinated at
least to the extent provided in this Article to the payment of, all Senior Indebtedness which may
at the time be outstanding or any securities issued in respect thereof under any such plan of
reorganization or readjustment) in respect of the Subordinated Securities (for principal, premium
or interest). Upon any such dissolution or winding up or liquidation or reorganization, any payment
or distribution of assets or securities of the Corporation of any kind or character, whether in
cash, property or securities (other than as aforesaid), to which the Holders of the Subordinated
Securities or the Trustee on their behalf would be entitled, except for the provisions of this
Article, shall be made by the Corporation or by any receiver, trustee in bankruptcy, liquidating
trustee, agent or other person making such payment or distribution, direct to the holders of Senior
Indebtedness or their representatives to the extent necessary to pay all Senior Indebtedness in
full, in money or money’s worth, after giving effect to any concurrent payment or distribution to
or for the holders of Senior Indebtedness. In the event that, notwithstanding the foregoing, the
Trustee or the Holder of any Subordinated Security shall, under the circumstances described in the
two preceding sentences, have received any payment or distribution of assets or securities of the
Corporation of any kind or character, whether in cash, property or securities (other than as
aforesaid) before all Senior Indebtedness is paid in full or payment thereof provided for in money
or money’s worth, and if such fact shall then have been made known to the Trustee or, as the case
may be, such Holder, then such payment or distribution of assets or securities of the Corporation
shall be paid over or delivered forthwith to the receiver, trustee in bankruptcy, liquidating
trustee, agent or other person making payment or distribution of assets or securities of the
Corporation for application to the payment of all Senior Indebtedness remaining unpaid, to the
extent necessary to pay all Senior Indebtedness in full, in money or money’s worth, after giving
effect to any concurrent payment or distribution to or for the holders of Senior Indebtedness.

     Subject to the payment in full, in money or money’s worth, of all Senior Indebtedness, the
Holders of the Subordinated Securities (together with the holders of any indebtedness of the
Corporation which is subordinate in right of payment to the payment in full of all Senior
Indebtedness and which is not subordinate in right of payment to the Subordinated Securities) shall
be subrogated to the rights of the holders of Senior Indebtedness to receive payments or
distribution of assets or securities of the Corporation applicable to Senior Indebtedness until the
principal of (and premium, if any) and interest on the Senior Indebtedness shall be paid in full.
No such payments or
distributions applicable to Senior Indebtedness shall, as between the Corporation, its creditors
other than the holders of Senior Indebtedness, and the Holders of the Subordinated Securities, be
deemed to be a payment by the Corporation to or on account of the Subordinated Securities, it being
understood that the provisions of this Article

45

 

are and are intended solely for the purpose of
defining the relative rights of the Holders of the Subordinated Securities, on the one hand, and
the holders of Senior Indebtedness, on the other hand. Nothing contained in this Article or
elsewhere in this Indenture or in the Subordinated Securities is intended to or shall impair, as
between the Corporation and the Holders of Subordinated Securities, the obligation of the
Corporation, which is unconditional and absolute, to pay to the Holders of the Subordinated
Securities the principal of (and premium, if any) and interest on the Subordinated Securities as
and when the same shall become due and payable in accordance with their terms, or to affect (except
to the extent specifically provided above in this paragraph) the relative rights of the Holders of
the Subordinated Securities and creditors of the Corporation other than the holders of Senior
Indebtedness. Nothing contained herein shall prevent the Trustee or the Holder of any Subordinated
Security from exercising all remedies otherwise permitted by applicable law upon default under this
Indenture, subject to the rights, if any, under this Article, of the holders of Senior Indebtedness
in respect of assets or securities of the Corporation of any kind or character, whether cash,
property or securities, received upon the exercise of any such remedy.

     Upon any payment or distribution of assets or securities of the Corporation referred to in
this Article, the Trustee and the Holders of the Subordinated Securities shall be entitled to rely
upon any order or decree of a court of competent jurisdiction in which such dissolution, winding
up, liquidation or reorganization proceedings are pending, and upon a certificate of the receiver,
trustee in bankruptcy, liquidating trustee, agent or other person making any such payment or
distribution, delivered to the Trustee or to the Holders of the Subordinated Securities for the
purpose of ascertaining the persons entitled to participate in such distribution, the holders of
Senior Indebtedness and other indebtedness of the Corporation, the amount thereof or payable
thereon, the amount or amounts paid or distributed thereon and all other facts pertinent thereto or
to this Article.

     If:

     (i) there shall have occurred a default in the payment on account of the
principal of (or premium, if any) or interest on or other monetary amounts due and payable on any
Senior Indebtedness, or

     (ii) any other default shall have occurred concerning any Senior Indebtedness which permits
the holder or holders thereof to accelerate the maturity of such Senior Indebtedness following
notice, the lapse of time, or both, or

     (iii) during any time Senior Indebtedness is outstanding, the principal of, and accrued
interest on, any series of Subordinated Securities shall have been declared due and payable upon an
Event of Default pursuant to Section 502 hereof (and such declaration shall not have been rescinded
or annulled pursuant to this Indenture);

then, unless and until such default shall have been cured or waived or shall have ceased to exist,
or such declaration shall have been waived, rescinded or annulled, no payment shall be made by the
Corporation on account of the principal (or premium, if any) or interest on the Subordinated
Securities.

     The Trustee shall be entitled to rely on the delivery to it of a written notice by a Person
representing himself to be a holder of Senior Indebtedness (or a representative of such holder or a
trustee under any indenture under which any instruments evidencing any such Senior Indebtedness may
have been issued) to establish that such notice has been given by a holder of such Senior
Indebtedness or such representative or trustee on behalf of such holder. In the event that the
Trustee determines in good faith that further evidence is required with respect to the right of any
Person as a holder of Senior Indebtedness to participate in any payment or distribution pursuant to
this Article Fifteen, the Trustee may request such Person to furnish evidence to the reasonable
satisfaction of the Trustee as to the amount of Senior Indebtedness held by such Person, the extent
to which such Person is entitled to participate in such payment or distribution and any other facts
pertinent to the right of such Person under this Article Fifteen, and, if such evidence is not
furnished, the Trustee may defer any payment to such Person pending judicial determination as to
the right of such Person to receive such payment or distribution.

     Section 1503. Payment Prior to Dissolution or Default.

     Nothing contained in this Article or elsewhere in this Indenture, or in any of the
Subordinated Securities, shall prevent (a) the Corporation, at any time except under the conditions
described in Section 1502 or during the pendency of any dissolution or winding up or total or
partial liquidation or reorganization proceedings therein referred to, from making payments at any
time of principal of (or premium, if any) or interest on Subordinated Securities or from depositing
with the Trustee or any Paying Agent moneys for such payments, or (b) the application by the
Trustee or any Paying Agent of any moneys deposited with it under this Indenture to the payment of
or on account of the principal of (or premium, if any) or interest on Subordinated Securities to
the Holders entitled thereto if such payment would not have been prohibited by the provisions of
Section 1502 on the day such moneys were so deposited.

     Notwithstanding the provisions of Section 1501 or any other provision of this Indenture, the
Trustee and any Paying Agent shall not be charged with knowledge of the existence of any Senior
Indebtedness, or of the occurrence of any default with respect to Senior Indebtedness of the
character described in Section 1502, or of any other facts which would prohibit the making of any
payment of moneys to or by the Trustee or such Paying Agent, unless and until the Trustee shall
have received, no later than three Business Days prior to such payment, written notice thereof from
the Corporation or from a holder of such Senior Indebtedness and the Trustee shallnot be affected
by any such notice which may be received by it on or after such third Business Day.

     Section 1504. Securityholders Authorize Trustee to Effectuate Subordination of Securities.

     Each Holder of Subordinated Securities by his or her acceptance thereof authorizes and
expressly directs the Trustee on his or her behalf to take such action in accordance with the terms
of this Indenture as may be necessary or appropriate to effectuate the subordination provisions
contained in this Article Fifteen and to protect the rights of the Holders of Subordinated
Securities pursuant to this Indenture, and appoints the Trustee his or her attorney-in-fact for
such purpose.

     Section 1505. Right of Trustee to Hold Senior Indebtedness.

     The Trustee shall be entitled to all of the rights set forth in this Article Fifteen in
respect of any Senior Indebtedness at any time held by it to the same extent as any other holder of
Senior Indebtedness, and nothing in this Indenture shall be construed to deprive the Trustee of any
of its rights as such holder.

     Section 1506. Article Fifteen Not to Prevent Events of Default.

     The failure to make a payment on account of principal of, premium, if any, or interest on the
Subordinated Securities by reason of any provision of this Article Fifteen shall not be construed
as preventing the occurrence of an Event of Default under Section 501 or an event which with the
giving of notice or lapse of time, or both, would become an Event of Default or in any way prevent
the Holders of Subordinated Securities from exercising any right hereunder other than the right to
receive payment on the Subordinated Securities.

     Section 1507. No Fiduciary Duty of Trustee to Holders of Senior Indebtedness.

     The Trustee shall not be deemed to owe any fiduciary duty to the holders of Senior
Indebtedness, and shall not be liable to any such holders (other than for its willful misconduct,
bad faith or negligence) if it shall in good faith mistakenly pay over or distribute to the Holders
of Subordinated Securities or the Corporation or any other Person, cash, property or securities to
which any holders of Senior Indebtedness shall be entitled by virtue of this Article Fifteen or
otherwise. Nothing in this Section 1507 shall affect the obligation of any other such Person to
hold such payment for the benefit of, and to pay such payment over to, the holders of Senior
Indebtedness or their representative. Nothing in this Article Fifteen shall apply to amounts due
the Trustee pursuant to Section 607 or any
other Section of this Indenture.

     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.
