Securities are valid obligations of the Company;

provided, however, that unless otherwise provided with respect to any Securities of any
series pursuant to Section 3.1, in determining whether the Holders of the requisite
principal amount of the Outstanding Securities have given any request, demand,
authorization, direction, notice, consent or waiver hereunder, or whether sufficient funds
are available for redemption or for any other purpose, and for the purpose of making the
calculations required by section 313 of the Trust Indenture Act or are present at a meeting
of Holders for quorum purposes, (w) the principal amount of any Original Issue Discount
Securities that may be counted in making such determination or calculation and that shall be
deemed to be Outstanding for such purpose shall be equal to the amount of principal thereof
that would be (or shall have been declared to be) due and payable, at the time of such
determination, upon a declaration of acceleration of the maturity thereof pursuant to
Section 5.2, (x) the principal amount of any Security denominated in one or more Foreign
Currencies or currency units that may be counted in making such determination or calculation
and that shall be deemed Outstanding for such purpose shall be equal to the Dollar
equivalent, determined as of the date such Security is originally issued by the Company as
set forth in an Exchange Rate Officer’s Certificate delivered to the Trustee, of the
principal amount (or, in the case of an Original Issue Discount Security, the Dollar
equivalent, determined as of such date of original issuance, of the amount determined as
provided in clause (w) above) of such Security, (y) unless otherwise provided with respect
to such Security pursuant to Section 3.1, the principal amount of any Indexed Security that
may be counted in making such determination or calculation and that shall be deemed
Outstanding for such purpose shall be equal to the principal face amount of such Indexed
Security at original issuance, and (z) Securities owned by the Company or any other obligor
upon the Securities or any Affiliate of the Company or of such other obligor shall be
disregarded and deemed not to be Outstanding, except that, in determining whether the
Trustee shall be protected in making such calculation or in relying upon any such request,
demand, authorization, direction, notice, consent or waiver, or determination as to the
presence of a quorum, only Securities which a Responsible Officer of the Trustee knows to be
so owned shall be so disregarded.

     Section 1.2. COMPLIANCE CERTIFICATES AND OPINIONS. Upon any application or request by the
Company to the Trustee to take any action under any provision of this Indenture, the Company shall
furnish to the Trustee an Officer’s Certificate stating that all conditions precedent, if any,
provided for in this Indenture relating to the proposed action have been complied with and an
Opinion of Counsel stating that in the opinion of such counsel all such conditions precedent, if
any, have been complied with, except that in the case of any application or request as to which the
furnishing of such documents is specifically required by any provision of this Indenture relating
to such particular application or request, no additional certificate or opinion need be furnished.

     Every certificate or opinion with respect to compliance with a condition or covenant provided
for in this Indenture (other than pursuant to Sections 2.3 and 9.7) shall include:

     (1) a statement that the individual signing such certificate or opinion has read such
condition or covenant and any definitions in this Indenture that are used in such certificate or
opinion;

     (2) 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;

8

 

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

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

     Section 1.3. 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 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 Company may be based, insofar as it relates to
legal matters, upon a certificate or opinion of, or representations by, counsel, unless such
officer knows 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 Company stating that the information with
respect to such factual matters is in the possession of the Company, unless such counsel knows that
the certificate or opinion or representations as to such matters are erroneous.

     Any certificate or opinion of an officer of the Company or of counsel may be based, insofar as
it relates to accounting matters, upon a certificate or opinion of or representations by an
accountant or firm of accountants in the employ of the Company, unless such officer or counsel, as
the case may be, knows that the certificate or opinions or representations as to such accounting
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.

     Section 1.4. ACTS OF HOLDERS. (a) Any request, demand, authorization, direction, notice,
consent, waiver or other action provided by this Indenture to be given 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 Company. Such instrument or
instruments (and the action embodied therein and evidenced thereby) are herein sometimes referred
to as the “Act” of the Holders signing such instrument or instruments. Proof of execution of any
such instrument or of a writing appointing any such agent shall be sufficient for any purpose of
this Indenture and conclusive in favor of the Trustee and the Company, if made in the manner
provided in this Section.

9

 

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

     (c) The ownership of Bearer Securities may be proved by the production of such Bearer
Securities or by a certificate executed by any trust company, bank, banker or other depository,
wherever situated, if such certificate shall be deemed by the Trustee to be satisfactory, showing
that at the date therein mentioned such Person had on deposit with such depository, or exhibited to
it, the Bearer Securities therein described; or such facts may be proved by the certificate or
affidavit of the Person holding such Bearer Securities, if such certificate or affidavit is deemed
by the Trustee to be satisfactory. The Trustee and the Company may assume that such ownership of
any Bearer Security continues until (i) another such certificate or affidavit bearing a later date
issued in respect of the same Bearer Security is produced, (ii) such Bearer Security is produced to
the Trustee by some other Person, (iii) such Bearer Security is surrendered in exchange for a
Registered Security or (iv) such Bearer Security is no longer Outstanding. The ownership of Bearer
Securities may also be proved in any other manner which the Trustee deems sufficient.

     (d) The ownership of Registered Securities shall be proved by the Register (as defined in
Section 3.5 below).

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

     (f) If the Company shall solicit from the Holders of any series any request, demand,
authorization, direction, notice, consent, waiver or other Act, the Company may, at its option, fix
in advance a record date for the determination of Holders of such series entitled to give such
request, demand, authorization, direction, notice, consent, waiver or other Act, but the Company
shall have no obligation to do so. If such a record date is fixed, such request, demand,
authorization, direction, notice, consent, waiver or other Act may be given before or after such
record date, but only the Holders of such series of record at the close of business on such record
date shall be deemed to be Holders for the purposes of determining whether Holders of the requisite
proportion of Outstanding Securities of such series have authorized or agreed or consented to such
request, demand, authorization, direction, notice, consent, waiver or other Act, and for that
purpose the Outstanding Securities of such series 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 taken on or prior to the applicable Expiration Date (as defined below)
by Holders of the requisite amount of Outstanding Securities of such series on such record date.
Nothing in this paragraph shall be construed to prevent the Company from

10

 

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 amount of Outstanding
Securities on the date such action is taken. Promptly after any record date is set pursuant to
this paragraph, the Company, at its own expense, shall cause notice of such record date, the
proposed action by Holders and the applicable Expiration Date to be given to the Trustee in writing
and to each Holder of Notes in the manner set forth in Section 1.6.

     With respect to any record date set pursuant to this Section 1.4, the Company may designate
any date as the “Expiration Date” and from time to time may change the Expiration Date to any
earlier or later day; provided that no such change shall be effective unless notice of the proposed
new Expiration Date is given to the Trustee, and to each Holder of Securities of the applicable
series in the manner set forth in Section 1.6 on or prior to the existing Expiration Date. If an
Expiration Date is not designated with respect to any record date pursuant to this Section, the
Company 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.

     (g) 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.

     (h) The Company and the Trustee may make reasonable rules for action by or at a meeting of
Holders.

     Section 1.5. NOTICES, ETC., TO TRUSTEE AND COMPANY. Any request, demand, authorization,
direction, notice, consent, waiver or Act of Holders or other document provided or permitted by
this Indenture to be made upon, given or furnished to, or filed with,

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

     (2) the Company by the Trustee or by any Holder shall be sufficient for every purpose
hereunder (unless otherwise herein expressly provided) if in writing and mailed, first-class
postage prepaid, to the Company addressed to it at Third Wave Technologies, Inc., 502 South Rosa
Road, Madison, Wisconsin, 53719, attention: General Counsel, or at any other address previously
furnished in writing to the Trustee by the Company.

     Section 1.6. NOTICE TO HOLDERS; WAIVER. Where this Indenture provides for notice to Holders
of any event, (i) if any of the Securities affected by such event are Registered Securities, such
notice to the Holders thereof shall be sufficiently given (unless otherwise herein or in the terms
of such Securities expressly provided) if in writing and mailed, first-class postage prepaid, to
each such Holder affected by such event, at his address as it appears in the Register,

11

 

within the time prescribed for the giving of such notice and, (ii) if any of the Securities
affected by such event are Bearer Securities, notice to the Holders thereof shall be sufficiently
given (unless otherwise herein or in the terms of such Bearer Securities expressly provided) if
published once in an Authorized Newspaper in New York, New York, and in such other city or cities,
if any, as may be specified as contemplated by Section 3.1.

     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 of Registered Securities or the sufficiency of any notice
to Holders of Bearer Securities given as provided herein. In any case where notice is given to
Holders by publication, neither the failure to publish such notice, nor any defect in any notice so
published, shall affect the sufficiency of such notice with respect to other Holders of Bearer
Securities or the sufficiency of any notice to Holders of Registered Securities given as provided
herein. Any notice mailed to a Holder in the manner herein prescribed shall be conclusively deemed
to have been received by such Holder, whether or not such Holder actually receives such notice.

     If by reason of the suspension of regular mail service or by reason of any other cause it
shall be impracticable to give such notice as provided above, then such notification as shall be
made with the approval of the Trustee (such approval not to be unreasonably withheld) shall
constitute a sufficient notification for every purpose hereunder. If it is impossible or, in the
opinion of the Trustee, impracticable to give any notice by publication in the manner herein
required, then such publication in lieu thereof as shall be made with the approval of the Trustee
shall constitute a sufficient publication of such notice.

     Any request, demand, authorization, direction, notice, consent or waiver required or permitted
under this Indenture shall be in the English language, except that any published notice may be in
an official language of the country of publication.

     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 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.

     Section 1.7. HEADINGS AND TABLE OF CONTENTS. The Article and Section headings herein and the
Table of Contents are for convenience only and shall not affect the construction hereof.

     Section 1.8. SUCCESSOR AND ASSIGNS. All covenants and agreements in this Indenture by the
Company shall bind its successor and assigns, whether so expressed or not.

     Any act or proceeding that is required or permitted by any provision of this Indenture and
that is authorized or required to be done or performed by any board, committee or officer of the
Company shall and may be done and performed with like force and effect by the like board, committee
or officer of any corporation that shall at the time be the successor or assign of the Company.

12

 

     Section 1.9. SEPARABILITY. In case any provision of this Indenture or 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 1.10. BENEFITS OF INDENTURE. Nothing in this Indenture or in the Securities,
expressed or implied, shall give to any Person, other than the parties hereto and their successors
hereunder, any Agent and the Holders, any benefit or any legal or equitable right, remedy or claim
under this Indenture.

     Section 1.11. GOVERNING LAW. UNLESS OTHERWISE PROVIDED WITH RESPECT TO ANY SECURITIES OF ANY
SERIES PURSUANT TO SECTION 3.1, THIS INDENTURE, THE SECURITIES AND ANY COUPONS APPERTAINING THERETO
SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, INCLUDING
ALL MATTERS OF CONSTRUCTION, VALIDITY AND PERFORMANCE. This Indenture is subject to the Trust
Indenture Act and if any provision hereof limits, qualifies or conflicts with a provision included
in this Indenture which is required by the Trust Indenture Act, the latter provision shall control.
If any provision of this Indenture modifies or excludes any provision of the Trust Indenture Act
that 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, whether or not such provision of
this Indenture refers expressly to such provision of the Trust Indenture Act.

     Section 1.12. LEGAL HOLIDAYS. Unless otherwise provided with respect to any Security or
Securities pursuant to Section 3.1, in any case where any Interest Payment Date, Redemption Date,
sinking fund payment date, Stated Maturity or Maturity or other payment date of any Security shall
not be a Business Day at any Place of Payment, then, notwithstanding any other provision of this
Indenture or any Security or coupon, payment of principal, premium, if any or interest or other
payments 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 such
date; provided that no interest shall accrue on the amount so payable for the period from and after
such Interest Payment Date, Redemption Date, sinking fund payment date, Stated Maturity or Maturity
or other payment date, as the case may be.

     Section 1.13. NO RECOURSE AGAINST OTHERS. No past, present or future director, officer,
employee, agent, member, manager, trustee or stockholder, as such, of the Company or any successor
Person shall have any liability for any obligations of the Company or any successor Person, either
directly or through the Company or any successor Person, under the Securities or this Indenture or
for any claim based on, in respect of or by reason of such obligations or their creation, whether
by virtue of any rule of law, statute or constitutional provision or by the enforcement of any
assessment or by any legal or equitable proceeding or otherwise. By accepting a Security, each
Holder agrees to the provisions of this Section 1.13 and waives and releases all such liability.
Such waiver and release shall be part of the consideration for the issue of the Securities.

     Section 2.3. SECURITIES IN GLOBAL FORM. If Securities of or within a series are issuable in
whole or in part in global form, any such Security may provide that it shall represent the
aggregate or specified amount of Outstanding Securities from time to time endorsed thereon and may
also provide that the aggregate amount of Outstanding Securities represented thereby may from time
to time be reduced or increased to reflect exchanges. Any endorsement of a Security in global form
to reflect the amount, or any increase or decrease in the amount, or changes in the rights of
Holders, of Outstanding Securities represented thereby, shall be made in such manner and by such
Person or Persons as shall be specified therein or in the Company Order to be delivered to the
Trustee pursuant to Section 3.3 or 3.4. Subject to the provisions of Section 3.3 and, if
applicable, Section 3.4, the Trustee shall deliver and redeliver any security in permanent global
form in the manner and upon instructions given by the Person or Persons specified therein or in the
applicable Company Order. Any instructions by the Company with respect to endorsement or delivery
or redelivery of a Security in global form shall be in writing but need not comply with Section 1.2
hereof and need not be accompanied by an Opinion of Counsel.

     The provisions of the last paragraph of Section 3.3 shall apply to any Security in global form

the Security in global form together with written instructions (which need not comply with Section
1.2 and need not be accompanied by an Opinion of Counsel) with regard to the reduction in the
principal amount of Securities represented thereby, together with the written statement
contemplated by the last paragraph of Section 3.3.

in permanent global form shall be made to the Person or Persons specified therein.

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 Depository to a nominee of the Depository or
by a nominee of the Depository to the Depository or another nominee of the Depository or by
the Depository or any such nominee to a successor Depository or a nominee of such successor
Depository. Every Security authenticated and delivered upon registration of, or in exchange

any interest on any Bearer Securities of the series shall be payable;

     (15) if the principal amount payable at the Maturity of any Securities of the series will not
be determinable as of one or more dates prior to Maturity, the amount which shall be deemed to be
the principal amount of such Securities as of any such date hereunder or thereunder, or, if other
than as provided in the definition of the term “Outstanding”, which shall be deemed to be
Outstanding as of any date prior to the Stated Maturity (or, in any such case, the manner in which
such amount deemed to be the principal amount shall be determined) and, if necessary, the manner of
determining the equivalent thereof in U.S. currency;

whether beneficial owners of interests in any Securities of the series in global form may exchange

any such exchange may occur;

     (27) the priority, ranking or subordination, if any, of the Securities of the series;

     (28) if the Securities of the series will be governed by, and the extent to which such
Securities will be governed by, any law other than the laws of the state of New York;

     (29) the terms, if any, of any guarantee of the payment of principal, premium and interest
with respect to Securities of the series and any corresponding changes to the provisions of this
Indenture as then in effect;

     (30) the terms, if any, of the transfer, mortgage, pledge or assignment as security for the
Securities of the series of any properties, assets, moneys, proceeds, securities or other
collateral, including whether certain provisions in the Trust Indenture Act are applicable and any
corresponding changes to provisions of this Indenture as then in effect; and

     (31) any other terms of the series, including any terms which may be required by or advisable

with the marketing of Securities of the series.

     (c) The terms applicable to the Securities of any one series and coupons, if any, appertaining
to any Bearer Securities of such series need not be identical but may vary as may be provided (i)
by a Board Resolution, (ii) by action taken pursuant to a Board Resolution and (subject to Section
3.3) set forth, or determined in the manner provided, in the related Officers’ Certificate or (iii)
in an indenture supplemental hereto. All Securities of any one series need not be issued at the
same time and, unless otherwise provided, a series may be reopened, without the consent of the
Holders, for issuances of additional Securities of such series.

19

 

     (d) If any of the terms of the Securities of any series are established by action taken
pursuant to a Board Resolution, a copy of such Board Resolution shall be certified by the Corporate
Secretary or an Assistant Secretary of the Company and delivered to the Trustee at or prior to the
delivery of the Officers’ Certificate setting forth, or providing the manner for determining, the
terms of the Securities of such series, and, if such Board Resolution delegates a particular action
to another Person, an appropriate record of any such action taken pursuant thereto, shall be
delivered to the Trustee prior to the authentication and delivery thereof.

     (e) Except as may be otherwise expressly provided in the applicable Board Resolutions or
supplemental indenture, as contemplated by this Section 3.1, the Securities of any Series shall
rank PARI PASSU with the Securities of each other Series.

     Section 3.2. DENOMINATIONS. Unless otherwise provided as contemplated by Section 3.1, any
Registered Securities of a series shall be issuable in denominations of $1,000 and any integral
multiple thereof and any Bearer Securities of a series shall be issuable in the denomination of
$5,000 and any integral multiple thereof.

     Section 3.3. EXECUTION, AUTHENTICATION, DELIVERY AND DATING. Securities shall be executed on
behalf of the Company by the Chief Executive Officer, the Chief Financial Officer, the President,
or any Vice President, the Treasurer or the Corporate Secretary of the Company. The seal of the
Company, if any, may be in the form of a facsimile thereof and may be impressed, affixed, imprinted
or otherwise reproduced on the Securities. The signatures of any of these officers on the
Securities may be manual or facsimile. The coupons, if any, of Bearer Securities shall bear the
facsimile signature of the Chief Executive Officer, the Chief Financial Officer, the President, any
Vice President, the Treasurer the Corporate Secretary of the Company.

     Securities and coupons 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, the Company may deliver Securities, together with any
coupons appertaining thereto, of any series executed by the Company to the Trustee for
authentication, together with a Company Order for the authentication and delivery of such
Securities, and the Trustee in accordance with the Company Order shall authenticate and deliver
such Securities; 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 Company 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 a series have been established by or pursuant to one
or more Board Resolutions as permitted by Sections 2.1 and 3.1, 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 315(a) through (d) of

20

 

the Trust Indenture Act) shall be fully protected in relying upon, an Opinion of Counsel
substantially to the effect that,

     (1) the form of such Securities and any coupons have been established in conformity with the
provisions of this Indenture;

     (2) the terms of such Securities and any coupons 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 offered in a Periodic Offering, to any conditions
specified in such Opinion of Counsel; and

     (3) such Securities together with any coupons appertaining thereto, when authenticated and
delivered by the Trustee, issued by the Company in accordance with the provisions of this
Indenture, and delivered to and duly paid for by the purchasers thereof, and subject to any
conditions specified in such Opinion of Counsel, will constitute legal, valid and binding
obligations of the Company, enforceable in accordance with their terms, subject to bankruptcy,
insolvency, fraudulent transfer, reorganization, moratorium and other similar laws of general
applicability relating to or affecting the enforcement of creditors’ rights and to general equity
principles and except further as enforcement thereof may be limited by or subject to certain
exceptions and qualifications specified in such Opinion of Counsel, including in the case of any
Securities denominated in a Foreign Currency, (A) requirements that a claim with respect to any
Securities denominated other than in Dollars (or a foreign currency or foreign currency unit
judgment in respect of such claim) be converted into Dollars at a rate of exchange prevailing on a
date determined pursuant to applicable law or (B) governmental authority to limit, delay or
prohibit the making of payments in foreign currency or currency units or payments outside the
United States.

     Such Opinion of Counsel need express no opinion as to the enforceability of Section 6.8 or as
to whether a court in the United States would render a money judgment in a currency other than that
of the United States. Such counsel may rely on opinions of other counsel (copies of which shall be
delivered to the Trustee), and, to the extent such opinion involves factual matters, such counsel
may rely upon certificates of officers of the Company and certificates of public officials.

     Notwithstanding that such form or terms have been so established, the Trustee shall have the
right to decline to authenticate such Securities if, in the written opinion of counsel to the
Trustee (which counsel may be an employee of the Trustee), such action may not lawfully be taken or
if the Trustee in good faith by its board of directors or trustees, executive committee or a trust
committee of directors, trustees or vice presidents shall determine that such action would expose
the Trustee to personal liability.

     Notwithstanding the provisions of Section 3.1 and of the two preceding paragraphs, if all of
the Securities of any series are not to be issued at one time, it shall not be necessary to deliver
the Officers’ Certificate otherwise required pursuant to Section 3.1 or the Company Order and
Opinion of Counsel otherwise required pursuant to the two preceding paragraphs in connection with
the authentication of each Security of such series if such documents, with appropriate

21

 

modifications to cover such future issuances, 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 Company of any of such Securities, the form and terms thereof and
the legality, validity, binding effect and enforceability thereof, upon the Opinion of Counsel and
the other documents delivered pursuant to Sections 2.1 and 3.1 and this Section, as applicable, in
connection with the first authentication of Securities of such series.

     If the Company shall establish pursuant to Section 3.1 that the Securities of a series are to
be issued in whole or in part in global form, then, unless otherwise provided with respect to such
Securities pursuant to Section 3.1, the Company shall execute and the Trustee shall, in accordance
with this Section and the Company 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 amount
equal to the aggregate principal amount of the Outstanding Securities of such series to be
represented by such Security or Securities in global form, (ii) shall be registered, if a
Registered Security, in the name of the Depository for such Security or Securities in global form
or the nominee of such Depository, (iii) shall be delivered by the Trustee to such Depository or
pursuant to such Depository’s instruction and (iv) shall bear the legend set forth in Section 2.4.

     Unless otherwise established pursuant to Section 3.1, each Depository designated pursuant to
Section 3.1 for a Registered Security in global form must, at the time of its designation and at
all times while it serves as Depository, be a clearing agency registered under the Securities
Exchange Act of 1934 and any other applicable statute or regulation. Neither the Company nor the
Trustee shall have any responsibility to determine if the Depository is so registered.

     Each Depository shall enter into an agreement with the Company and the Trustee, as agent,
governing the respective duties and rights of such Depository, the Company and the Trustee, as
agent, with regard to Securities issued in global form.

     Each Registered Security shall be dated the date of its authentication and each Bearer
Security shall be dated as of the date specified as contemplated by Section 3.1.

     No Security or coupon appertaining thereto shall be entitled to any benefits under this
Indenture or be valid or obligatory for any purpose until authenticated by the manual signature of
one of the authorized signatories of the Trustee or an Authenticating Agent and no coupon shall be
valid until the Security to which it appertains has been so authenticated. Such signature upon any
Security shall be conclusive evidence, and the only evidence, that such Security has been duly
authenticated and delivered under this Indenture and is entitled to the benefits of this Indenture.
Except as permitted by Section 3.6 or 3.7, the Trustee shall not authenticate and deliver any
Bearer Security unless all appurtenant coupons for interest then matured have been detached and
cancelled.

     Notwithstanding the foregoing, if any Security shall have been authenticated and delivered
hereunder but never issued and sold by the Company, and the Company shall deliver

22

 

such Security to the Trustee for cancellation as provided in Section 3.9 together with a
written statement (which need not comply with Section 1.2 and need not be accompanied by an Opinion
of Counsel) stating that such Security has never been issued and sold by the Company, for all
purposes of this Indenture such Security shall be deemed never to have been authenticated and
delivered hereunder and shall not be entitled to the benefits of this Indenture.

     Section 3.4. TEMPORARY SECURITIES. Pending the preparation of definitive Securities of any
series, the Company may execute and, upon Company Order, the Trustee shall authenticate and deliver
temporary Securities of such series which are printed, lithographed, typewritten, mimeographed or
otherwise produced, in any authorized denomination, substantially of the tenor and form, with or
without coupons, 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 conclusively evidenced by their execution of such Securities and
coupons, if any. In the case of Securities of any series, all or a portion of such temporary
Securities may be in global form.

     Except in the case of temporary Securities in global form, each of 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 preparation of definitive Securities of such series, the temporary Securities of such series
shall be exchangeable for definitive Securities of such series upon surrender of the temporary
Securities of such series at the office or agency of the Company pursuant to Section 9.2 in a Place
of Payment for such series, without charge to the Holder. Upon surrender for cancellation of any
one or more temporary Securities of any series (accompanied by any unmatured coupons appertaining
thereto), the Company shall execute and the Trustee shall authenticate and deliver in exchange
therefor a like principal amount of definitive Securities of the same series of authorized
denominations and of like tenor; provided, however, that no definitive Bearer Security shall be
delivered in exchange for a temporary Registered Security; and provided further that no definitive
Bearer Security shall be delivered in exchange for a temporary Bearer Security unless the Trustee
shall have received from the person entitled to receive the definitive Bearer Security a
certificate substantially in the form approved in or pursuant to the Board Resolutions relating
thereto and such delivery shall occur only outside the United States. 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 except as otherwise specified as
contemplated by Section 3.1.

     Section 3.5. REGISTRATION, TRANSFER AND EXCHANGE. The Company shall cause to be kept at the
Corporate Trust Office of the Trustee or in any office or agency to be maintained by the Company in
accordance with Section 9.2 in a Place of Payment or in such other place or medium as may be
specified pursuant to Section 3.1 a register for each series of Securities (the registers
maintained in such office or in any such office or agency of the Company in a Place of Payment
being herein sometimes referred to collectively as the “Register”) in which, subject to such
reasonable regulations as it may prescribe, the Company shall provide for the registration of
Registered Securities and the registration of transfers of Registered Securities. The Register
shall be in written form or any other form capable of being converted into written form within a
reasonable time. Unless otherwise provided as contemplated by Section 3.1, the Trustee is hereby
appointed “Registrar” for the purpose of

23

 

registering Registered Securities and transfers of Registered Securities, and for the purpose
of maintaining the Register in respect thereof, as herein provided.

     Upon surrender for registration of transfer of any Registered Security of any series at the
office or agency maintained pursuant to Section 9.2 in a Place of Payment for that series, the
Company shall execute, and the Trustee shall authenticate and deliver, in the name of the
designated transferee or transferees, one or more new Registered Securities of the same series, of
any authorized denominations and of a like aggregate principal amount.

     Unless otherwise provided as contemplated by Section 3.1, Bearer Securities (except for any
temporary global Bearer Securities) or any coupons appertaining thereto (except for coupons
attached to any temporary global Bearer Security) shall be transferable by delivery.

     Unless otherwise provided as contemplated by Section 3.1, at the option of the Holder,
Registered Securities of any series (except a Registered Security in global form) may be exchanged
for other Registered Securities of the same series, of any authorized denominations and of a like
aggregate principal amount containing identical terms and provisions, upon surrender of the
Registered Securities to be exchanged at such office or agency. Whenever any Registered Securities
are so surrendered for exchange, the Company shall execute, and the Trustee shall authenticate and
deliver, the Registered Securities which the Holder making the exchange is entitled to receive.
Unless otherwise specified as contemplated by Section 3.1, Bearer Securities may not be issued in
exchange for Registered Securities.

     Unless otherwise specified as contemplated by Section 3.1, at the option of the Holder, Bearer
Securities of such series may be exchanged for Registered Securities (if the Securities of such
series are issuable in registered form) or Bearer Securities (if Bearer Securities of such series
are issuable in more than one denomination and such exchanges are permitted by such series) of the
same series, of any authorized denominations and of like tenor and aggregate principal amount, upon
surrender of the Bearer Securities to be exchanged at any such office or agency, with all unmatured
coupons and all matured coupons in default thereto appertaining. If the Holder of a Bearer
Security is unable to produce any such unmatured coupon or coupons or matured coupon or coupons in
default, such exchange may be effected if the Bearer Securities are accompanied by payment in funds
acceptable to the Company and the Trustee in an amount equal to the face amount of such missing
coupon or coupons, or the surrender of such missing coupon or coupons may be waived by the Company
and the Trustee if there be furnished to them such security or indemnity as they may require to
save each of them and any Paying Agent harmless. If thereafter the Holder of such Security shall
surrender to any Paying Agent any such missing coupon in respect of which such a payment shall have
been made, such Holder shall be entitled to receive the amount of such payment; provided, however,
that, except as otherwise provided in Section 9.2, interest represented by coupons shall be payable
only upon presentation and surrender of those coupons at an office or agency located outside the
United States. Notwithstanding the foregoing, in case any Bearer Security of any series is
surrendered at any such office or agency in exchange for a Registered Security of the same series
after the close of business at such office or agency on (i) any Regular Record Date and before the
opening of business at such office or agency on the relevant Interest Payment Date, or (ii) any
Special Record Date and before the opening of business at such office or agency on the related date
for payment of Defaulted Interest, such Bearer Security shall be surrendered without the coupon

24

 

relating to such Interest Payment Date or proposed date of payment, as the case may be (or, if
such coupon is so surrendered with such Bearer Security, such coupon shall be returned to the
person so surrendering the Bearer Security), and interest or Defaulted Interest, as the case may
be, will not be payable on such Interest Payment Date or proposed date for payment, as the case may
be, in respect of the Registered Security issued in exchange for such Bearer Security, but will be
payable only to the Holder of such coupon, when due in accordance with the provisions of this
Indenture.

     Unless otherwise specified pursuant to Section 3.1 with respect to a series of Securities or
as otherwise provided below in this Section 3.5, owners of beneficial interests in Securities of
such series represented by a Security issued in global form will not be entitled to have Securities
of such series registered in their names, will not receive or be entitled to receive physical
delivery of Securities of such series in certificated form and will not be considered the Holders
or owners thereof for any purposes hereunder. Notwithstanding any other provision of this Section,
unless and until it is exchanged in whole or in part for Securities in certificated form in the
circumstances described below, a Security in global form representing all or a portion of the
Securities of a series may not be transferred or exchanged except as a whole by the Depository for
such series to a nominee of such Depository or by a nominee of such Depository to such Depository
or another nominee of such Depository or by such Depository or any such nominee to a successor
Depository for such series or a nominee of such successor Depository.

     If at any time the Depository for the Securities of a series notifies the Company that it is
unwilling or unable to continue as Depository for the Securities of such series or if at any time
the Depository for the Securities of such series notifies the Company that it shall no longer be
eligible under Section 3.3, the Company shall appoint a successor Depository with respect to the
Securities of such series. Unless otherwise provided as contemplated by Section 3.1, if a
successor Depository 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 3.1(b) (26) shall no longer be effective with respect to the
Securities of such series and the Company shall execute, and the Trustee, upon receipt of a Company
Order for the authentication and delivery of certificated Securities of such series of like tenor,
shall authenticate and deliver, Securities of such series of like tenor in certificated form, in
authorized denominations and in an aggregate principal amount equal to the principal amount of the
Security or Securities of such series of like tenor in global form in exchange for such Security or
Securities in global form.

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

     If specified by the Company pursuant to Section 3.1 with respect to a series of Securities,
the Depository for such series may surrender a Security in global form of such series in exchange

25

 

in whole or in part for Securities of such series in certificated form on such terms as are
acceptable to the Company and such Depository. Thereupon, the Company shall execute, and the
Trustee shall authenticate and deliver, without service charge,

     (i) to each Person specified by such Depository a new certificated Security or Securities of
the same series of like tenor, of any authorized denomination as requested by such Person in
aggregate principal amount equal to and in exchange for such Person’s beneficial interest in the
Security in global form; and

     (ii) to such Depository a new Security in global form of like tenor 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 certificated Securities delivered to Holders thereof.

     (iii) Upon the exchange of a Security in global form for Securities in certificated form, such
Security in global form shall be cancelled by the Trustee. Unless expressly provided with respect
to the Securities of any series that such Security may be exchanged for Bearer Securities,
Securities in certificated form issued in exchange for a Security in global form pursuant to this
Section shall be registered in such names and in such authorized denominations as the Depository
for such Security in global form, pursuant to instructions from its direct or indirect participants
or otherwise, shall instruct the Trustee. The Trustee shall deliver such Securities to the Persons
in whose names such Securities are so registered.

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

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

     Unless otherwise provided as contemplated by Section 3.1, no service charge shall be made for
any registration of transfer or for any exchange of Securities, but the Company may require payment
of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection
with any registration or transfer or exchange of Securities, other than exchanges pursuant to
Section 3.4 or 10.7 not involving any transfer.

     Unless otherwise provided as contemplated by Section 3.1, none of the Company, the Registrar
or the Trustee shall be required (i) to issue, register the transfer of, or exchange any Securities
for a period beginning at the opening of 15 Business Days before any selection for redemption of
Securities of like tenor and of the series of which such Security is a part and

26

 

ending at the close of business on the earliest date on which the relevant notice of
redemption is deemed to have been given to all Holders of Securities of like tenor and of such
series to be redeemed; (ii) to register the transfer of or exchange any Registered Security so
selected for redemption, in whole or in part, except the unredeemed portion of any Security being
redeemed in part; or (iii) to exchange any Bearer Security so selected for redemption, except that
such a Bearer Security may be exchanged for a Registered Security of that series and like tenor;
provided that such Registered Security shall be simultaneously surrendered for redemption.

     Section 3.6. REPLACEMENT SECURITIES. If a mutilated Security or a Security with a mutilated
coupon appertaining to it is surrendered to the Trustee, together with, in proper cases, such
security or indemnity as may be required by the Company or the Trustee to save each of them
harmless, the Company shall execute and the Trustee shall authenticate and deliver a replacement
Registered Security, if such surrendered Security was a Registered Security, or a replacement
Bearer Security with coupons corresponding to the coupons appertaining to the surrendered Security,
if such surrendered Security was a Bearer Security, of the same series and date of maturity.

     If there shall be delivered to the Company and the Trustee (i) evidence to their satisfaction
of the destruction, loss or theft of any Security or Security with a destroyed, lost or stolen
coupon and (ii) such security or indemnity as may be required by them to save each of them and any
agent of either of them harmless, then, in the absence of notice to the Company or the Trustee that
such Security or coupon has been acquired by a bona fide purchaser, the Company shall execute and
the Trustee shall authenticate and deliver in lieu of any such destroyed, lost or stolen Security
or in exchange for the Security to which a destroyed, lost or stolen coupon appertains (with all
appurtenant coupons not destroyed, lost or stolen), a replacement Registered Security, if such
Holder’s claim appertains to a Registered Security, or a replacement Bearer Security with coupons
corresponding to the coupons appertaining to the destroyed, lost or stolen Bearer Security or the
Bearer Security to which such lost, destroyed or stolen coupon appertains, if such Holder’s claim
appertains to a Bearer Security, of the same series and principal amount, containing identical
terms and provisions and bearing a number not contemporaneously outstanding with coupons
corresponding to the coupons, if any, appertaining to the destroyed, lost or stolen Security.

     In case any such mutilated, destroyed, lost or stolen Security or coupon has become or is
about to become due and payable, the Company in its discretion may, instead of issuing a new
Security or coupon, pay such Security or coupon; provided, however, that payment of principal of
and any premium or interest on Bearer Securities shall, except as otherwise provided in Section
9.2, be payable only at an office or agency located outside the United States and, unless otherwise
specified as contemplated by Section 3.1, any interest on Bearer Securities shall be payable only
upon presentation and surrender of the coupons appertaining thereto.

     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, its agents and counsel) connected therewith.

27

 

     Every new Security of any series with its coupons, if any, issued pursuant to this Section in
lieu of any destroyed, lost or stolen Security, or in exchange for a Security to which a destroyed,
lost or stolen coupon appertains, shall constitute an original additional contractual obligation of
the Company, whether or not the destroyed, lost or stolen Security and its coupon, if any, or the
destroyed, lost or stolen coupon, 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 and their coupons, if any, 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 or coupons.

     Section 3.7. PAYMENT OF INTEREST; INTEREST RIGHTS PRESERVED. (a) Unless otherwise provided
as contemplated by Section 3.1, interest, if any, on any Registered 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 at the office or agency maintained for such
purpose pursuant to 9.2; provided, however, that at the option of the Company, interest on any
series of Registered Securities that bear interest may be paid (i) by check mailed to the address
of the Person entitled thereto as it shall appear on the Register of Holders of Securities of such
series or (ii) by wire transfer to an account maintained by the Person entitled thereto as
specified in the Register of Holders of Securities of such series.

     Unless otherwise provided as contemplated by Section 3.1, (A) (i) interest, if any, on Bearer
Securities shall be paid only against presentation and surrender of the coupons for such interest
installments as are evidenced thereby as they mature and (ii) principal, original issue discount,
if any, and premium, if any, on Bearer Securities shall be paid only against presentation and
surrender of such Securities; in either case at the office of a Paying Agent located outside the
United States, unless the Company shall have otherwise instructed the Trustee in writing provided
that any such instruction for payment in the United States does not cause any Bearer Security to be
treated as a “registration-required obligation” under United States laws and regulations; (B) the
interest, if any, on any temporary Bearer Security shall be paid, as to any installment of interest
evidenced by a coupon attached thereto only upon presentation and surrender of such coupon as
provided in clause (A) above and, as to other installments of interest, only upon presentation of
such Security for notation thereon of the payment of such interest; and (C) if at the time a
payment of principal of premium, if any, or interest, if any, on a Bearer Security or coupon shall
become due, the payment of the full amount so payable at the office or offices of all the Paying
Agents outside the United States is illegal or effectively precluded because of the imposition of
exchange controls or other similar restrictions on the payment of such amount in Dollars, then the
Company may instruct the Trustee to make such payment at a Paying Agent located in the United
States, provided that provision for such payment in the United States would not cause such Bearer
Security to be treated as a “registration-required obligation” under United States laws and
regulations.

     (a) Unless otherwise provided as contemplated by Section 3.1, any interest on any Registered
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

28

 

payable to the Holder on the relevant Regular Record Date by virtue of having been such
Holder, and such Defaulted Interest may be paid by the Company, at its election in each case, as
provided in clause (1) or (2) below:

     (1) The Company may elect to make payment of any Defaulted Interest to the Persons in whose
names such Registered Securities of such series (or their respective Predecessor Securities) are
registered at the close of business on a Special Record Date for the payment of such Defaulted
Interest, which shall be fixed in the following manner. The Company shall 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 (1) provided. Thereupon the Trustee
shall fix a Special Record Date for the payment of such Defaulted Interest which shall be not more
than 15 days and not less than 10 days prior to the date of the proposed payment and not less than
10 days after the receipt by the Trustee of the notice of the proposed payment. The Trustee shall
promptly notify the Company of such Special Record Date and, in the name and at the expense of the
Company, shall cause notice of the proposed payment of such Defaulted Interest and the Special
Record Date therefor to be mailed, first-class postage prepaid, to each Holder of such Registered
Securities of such series at his address as it appears in the Register, not less than 10 days prior
to such Special Record Date. Notice of the proposed payment of such Defaulted Interest and the
Special Record Date therefor having been so mailed, such Defaulted Interest shall be paid to the
Persons in whose names such Registered Securities of such series (or their respective Predecessor
Securities) are registered at the close of business on such Special Record Date and shall no longer
be payable pursuant to the following clause (2).

     (2) The Company may make payment of any Defaulted Interest to the Persons in whose names such
Registered Securities of such series (or their respective Predecessor Securities) are registered at
the close of business on a specified date in any other lawful manner not inconsistent with the
requirements of any securities exchange on which such Registered 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 (2), such manner of payment shall be deemed
practicable by the Trustee.

     (b) Subject to the foregoing provisions of this Section and Section 3.5, 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 3.8. PERSONS DEEMED OWNERS. Prior to due presentment of any Registered Security for
registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may
treat the Person in whose name such Registered Security is registered as the owner of such
Registered Security for the purpose of receiving payment of principal of, premium, if any, and
(subject to Section 3.7) interest and any other payments on such Registered Security and for all
other purposes whatsoever, whether or not such Registered Security shall 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.

29

 

     The Company, the Trustee and any agent of the Company or the Trustee may treat the bearer of
any Bearer Security and the bearer of any coupon as the absolute owner of such Bearer Security or
coupon for the purpose of receiving payment thereof or on account thereof and for all other
purposes whatsoever, whether or not such Bearer Security or coupon 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 or any agent of the Company or the Trustee shall 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. Notwithstanding the
foregoing, with respect to any Security in global form, nothing herein shall prevent the Company or
the Trustee, or any agent of the Company or the Trustee, from giving effect to any written
certification, proxy or other authorization furnished by any Depository (or its nominee), as a
Holder, with respect to such Security in global form or impair, as between such Depository and
owners of beneficial interests in such Security in global form, the operation of customary
practices governing the exercise of the rights of such Depository (or its nominee) as Holder of
such Security in global form.

     Section 3.9. CANCELLATION. The Company at any time may deliver Securities and coupons to the
Trustee for cancellation. The Registrar and any Paying Agent shall forward to the Trustee any
Securities and coupons surrendered to them for replacement, for registration of transfer, or for
exchange or payment. The Trustee shall cancel all Securities and coupons surrendered for
replacement, for registration of transfer, or for exchange, payment, redemption or cancellation and
may destroy cancelled Securities and coupons and, if so destroyed, shall issue a certificate of
destruction to the Company. The Company may not issue new Securities to replace Securities that it
has paid or delivered to the Trustee for cancellation.

     Section 3.10. COMPUTATION OF INTEREST. Except as otherwise specified as contemplated by
Section 3.1, interest on the Securities of each series shall be computed on the basis of a 360-day
year of twelve 30-day months.

     Section 3.11. CURRENCY AND MANNER OF PAYMENT IN RESPECT OF SECURITIES. (a) Unless otherwise
specified with respect to any Securities pursuant to Section 3.1, with respect to Registered
Securities of any series and with respect to Bearer Securities of any series payment of the
principal of, premium, if any, interest, if any, and other amounts, if any, on any Registered or
Bearer Security of such series will be made in the currency or currencies or currency unit or units
in which such Registered Security or Bearer Security, as the case may be, is payable. The
provisions of this Section 3.11, including without limitation any defined terms specified herein,
may be modified or superseded in whole or in part pursuant to Section 3.1 with respect to any
Securities.

     (b) If expressly specified pursuant to Section 3.1, with respect to Registered Securities of
any series, Holders shall have the option, subject to paragraphs (d) and (e) below, to receive
payments of principal of, premium, if any, or interest, if any, on such Registered Securities in
any of the currencies or currency units which may be designated for such election by delivering to
the Trustee (or the applicable Paying Agent) a written election with signature

30

 

guarantees and in the applicable form established pursuant to Section 3.1, not later than the
close of business on the Election Date immediately preceding the applicable payment date. If a
Holder so elects to receive such payments in any such currency or currency unit, such election will
remain in effect for such Holder or any transferee of such Holder until changed by such Holder or
such transferee by written notice to the Trustee (or any applicable Paying Agent) for such series
of Registered Securities (but any such change must be made not later than the close of business on
the Election Date immediately preceding the next payment date to be effective for the payment to be
made on such payment date, and no such change of election may be made with respect to payments to
be made on any Registered Security of such series with respect to which an Event of Default has
occurred or with respect to which the Company has deposited funds pursuant to Article IV or with
respect to which a notice of redemption has been given by or on behalf of the Company). Any Holder
of any such Registered Security who shall not have delivered any such election to the Trustee (or
any applicable Paying Agent) not later than the close of business on the applicable Election Date
will be paid the amount due on the applicable payment date in the relevant currency or currency
unit as provided in Section 3.11(a). The Trustee (or the applicable Paying Agent) shall notify the
Company and the Exchange Rate Agent as soon as practicable after the Election Date of the aggregate
principal amount of Registered Securities for which Holders have made such written election.

     (c) If the election referred to in paragraph (b) above has been provided for with respect to
any Registered Securities of a series pursuant to Section 3.1, then, unless otherwise specified
pursuant to Section 3.1 with respect to any such Registered Securities, not later than the fourth
Business Day after the Election Date for each payment date for such Registered Securities, the
Exchange Rate Agent will deliver to the Company a written notice specifying, in the currency or
currencies or currency unit or units in which Registered Securities of such series are payable, the
respective aggregate amounts of principal of, premium, if any, and interest, if any, on such
Registered Securities to be paid on such payment date, and specifying the amounts in such currency
or currencies or currency unit or units so payable in respect of such Registered Securities as to
which the Holders of Registered Securities denominated in any currency or currencies or currency
unit or units shall have elected to be paid in another currency or currency unit as provided in
paragraph (b) above. If the election referred to in paragraph (b) above has been provided for with
respect to any Registered Securities of a series pursuant to Section 3.1, and if at least one
Holder has made such election, then, unless otherwise specified pursuant to Section 3.1, on the
second Business Day preceding such payment date the Company will deliver to the Trustee (or the
applicable Paying Agent) an Exchange Rate Officers’ Certificate in respect of the Dollar, Foreign
Currency or Currencies or other currency unit payments to be made on such payment date. Unless
otherwise specified pursuant to Section 3.1, the Dollar, Foreign Currency or Currencies or other
currency unit amount receivable by Holders of Registered Securities who have elected payment in a
currency or currency unit as provided in paragraph (b) above shall be determined by the Company on
the basis of the applicable Market Exchange Rate in effect on the second Business Day (the
“Valuation Date”) immediately preceding each payment date, and such determination shall be
conclusive and binding for all purposes, absent manifest error.

     (d) If a Conversion Event occurs with respect to a Foreign Currency or any other currency unit
in which any of the Securities are denominated or payable otherwise than pursuant to an election
provided for pursuant to paragraph (b) above, then, unless otherwise specified

31

 

pursuant to Section 3.1, with respect to each date for the payment of principal of, premium,
if any, and interest, if any, on the applicable Securities denominated or payable in such Foreign
Currency or such other currency unit occurring after the last date on which such Foreign Currency
or such other currency unit was used (the “Conversion Date”), the Dollar shall be the currency of
payment for use on each such payment date (but such Foreign Currency or such other currency unit
that was previously the currency of payment shall, at the Company’s election, resume being the
currency of payment on the first such payment date preceded by 15 Business Days during which the
circumstances which gave rise to the Dollar becoming such currency of payment no longer prevail).
Unless otherwise specified pursuant to Section 3.1, the Dollar amount to be paid by the Company to
the Trustee or any applicable Paying Agent and by the Trustee or any applicable Paying Agent to the
Holders of such Securities with respect to such payment date shall be, in the case of a Foreign
Currency other than a currency unit, the Dollar Equivalent of the Foreign Currency or, in the case
of a Foreign Currency that is a currency unit, the Dollar Equivalent of the Currency Unit, in each
case as determined by the Exchange Rate Agent in the manner provided in paragraph (f) or (g) below.

     (e) Unless otherwise specified pursuant to Section 3.1, if the Holder of a Registered Security
denominated in any currency or currency unit shall have elected to be paid in another currency or
currency unit or in other currencies as provided in paragraph (b) above, and (i) a Conversion Event
occurs with respect to any such elected currency or currency unit, such Holder shall receive
payment in the currency or currency unit in which payment would have been made in the absence of
such election and (ii) if a Conversion Event occurs with respect to the currency or currency unit
in which payment would have been made in the absence of such election, such Holder shall receive
payment in Dollars as provided in paragraph (d) of this Section 3.11 (but, subject to any
contravening valid election pursuant to paragraph (b) above, the elected payment currency or
currency unit, in the case of the circumstances described in clause (i) above, or the payment
currency or currency unit in the absence of such election, in the case of the circumstances
described in clause (ii) above, shall, at the Company’s election, resume being the currency or
currency unit of payment with respect to Holders who have so elected, but only with respect to
payments on payment dates preceded by 15 Business Days during which the circumstances which gave
rise to such currency or currency unit, in the case of the circumstances described in clause (i)
above, or the Dollar, in the case of the circumstances described in clause (ii) above, becoming the
currency or currency unit, as applicable, of payment, no longer prevail).

     (f) The “Dollar Equivalent of the Foreign Currency” shall be determined by the Exchange Rate
Agent and shall be obtained for each subsequent payment date by the Exchange Rate Agent by
converting the specified Foreign Currency into Dollars at the Market Exchange Rate on the
Conversion Date.

     (g) The “Dollar Equivalent of the Currency Unit” shall be determined by the Exchange Rate
Agent and, subject to the provisions of paragraph (h) below, shall be the sum of each amount
obtained by converting the Specified Amount of each Component Currency (as each such term is
defined in paragraph (h) below) into Dollars at the Market Exchange Rate for such Component
Currency on the Valuation Date with respect to each payment.

     (h) For purposes of this Section 3.11, the following terms shall have the following meanings:

32

 

     A “Component Currency” shall mean any currency which, on the Conversion Date, was a component
currency of the relevant currency unit.

     “Conversion Event” shall mean the cessation of use of (i) a Foreign Currency both by the
government of the country which issued such currency and for the settlement of transactions by a
central bank or other public institutions of or within the international banking community, or (ii)
any currency unit for the purposes for which it was established.

     “Election Date” shall mean the Regular Record Date for the applicable series of Registered
Securities as specified pursuant to Section 3.1 by which the written election referred to in
Section 3.11(b) may be made.

     “Exchange Rate Agent”, when used with respect to Securities of or within any series, shall
mean, unless otherwise specified with respect to any Securities pursuant to Section 3.1, a New York
Clearing House bank designated pursuant to Section 3.1 or Section 3.12.

     “Exchange Rate Officer’s Certificate” shall mean a certificate setting forth (i) the
applicable Market Exchange Rate or the applicable bid quotation and (ii) the Dollar or Foreign
Currency amounts of principal (and premium, if any) and interest, if any (on an aggregate basis and
on the basis of a Security having the lowest denomination principal amount in the relevant currency
or currency unit), payable with respect to a Security of any series on the basis of such Market
Exchange Rate or the applicable bid quotation, signed by the President, the Chief Executive
Officer, the Chief Financial Officer, any Vice President, the Treasurer, or any Assistant Treasurer
of the Company.

     “Market Exchange Rate” shall mean, unless otherwise specified with respect to any Securities
pursuant to Section 3.1, as of any date of determination, (i) for any conversion involving a
currency unit on the one hand and Dollars or any Foreign Currency on the other, the exchange rate
between the relevant currency unit and Dollars or such Foreign Currency calculated by the method
specified pursuant to Section 3.1 for the Securities of the relevant series, (ii) for any
conversion of Dollars into any Foreign Currency, the noon buying rate for such Foreign Currency for
cable transfers quoted in New York City as certified for customs purposes by the Federal Reserve
Bank of New York and (iii) for any conversion of one Foreign Currency into Dollars or another
Foreign Currency, the spot rate at noon local time in the relevant market at which, in accordance
with normal banking procedures, the Dollars or Foreign Currency into which conversion is being made
could be purchased with the Foreign Currency from which conversion is being made from major banks
located in New York City, London or any other principal market for Dollars or such purchased
Foreign Currency, in each case determined by the Exchange Rate Agent. Unless otherwise specified
with respect to any Securities pursuant to Section 3.1, in the event of the unavailability of any
of the exchange rates provided for in the foregoing clauses (i), (ii) and (iii), the Exchange Rate
Agent shall use, in its sole discretion and without liability on its part, such quotation of the
Federal Reserve Bank of New York as of the most recent available date, or quotations from one or
more major banks in New York City, London or other principal market for such currency or currency
unit in question (which may include any such bank acting as Trustee under this Indenture), or such
other quotations as the Exchange Rate Agent shall deem appropriate. Unless otherwise specified by
the Exchange Rate Agent, if there is more than one market for dealing in any currency or

33

 

currency unit by reason of foreign exchange regulations or otherwise, the market to be used in
respect of such currency or currency unit shall be that upon which a nonresident issuer of
securities designated in such currency or currency unit would purchase such currency or currency
unit in order to make payments in respect of such securities.

     A “Specified Amount” of a Component Currency shall mean the number of units of such Component
Currency or fractions thereof which such Component Currency represented in the relevant currency
unit on the Conversion Date. If after the Conversion Date the official unit of any Component
Currency is altered by way of combination or subdivision, the Specified Amount of such Component
Currency shall be divided or multiplied in the same proportion. If after the Conversion Date two
or more Component Currencies are consolidated into a single currency, the respective Specified
Amounts of such Component Currencies shall be replaced by an amount in such single currency equal
to the sum of the respective Specified Amounts of such consolidated Component Currencies expressed
in such single currency, and such amount shall thereafter be a Specified Amount and such single
currency shall thereafter be a Component Currency. If after the Conversion Date any Component
Currency shall be divided into two or more currencies, the Specified Amount of such Component
Currency shall be replaced by specified amounts of such two or more currencies, the sum of which,
at the Market Exchange Rate of such two or more currencies on the date of such replacement, shall
be equal to the Specified Amount of such former Component Currency and such amounts shall
thereafter be Specified Amounts and such currencies shall thereafter be Component Currencies. If,
after the Conversion Date of the relevant currency unit, a Conversion Event (other than any event
referred to above in this definition of “Specified Amount”) occurs with respect to any Component
Currency of such currency unit and is continuing on the applicable Valuation Date, the Specified
Amount of such Component Currency shall, for purposes of calculating the Dollar Equivalent of the
Currency Unit, be converted into Dollars at the Market Exchange Rate in effect on the Conversion
Date of such Component Currency.

     All decisions and determinations of the Exchange Rate Agent regarding the Dollar Equivalent of
the Foreign Currency, the Dollar Equivalent of the Currency Unit, the Market Exchange Rate and
changes in the Specified Amounts as specified above shall be in its sole discretion and shall, in
the absence of manifest error, be conclusive for all purposes and irrevocably binding upon the
Company, the Trustee (and any applicable Paying Agent) and all Holders of Securities denominated or
payable in the relevant currency, currencies or currency units. The Exchange Rate Agent shall
promptly give written notice to the Company and the Trustee of any such decision or determination.

     In the event that the Company determines in good faith that a Conversion Event has occurred
with respect to a Foreign Currency, the Company will promptly give written notice thereof to the
Trustee (or any applicable Paying Agent) and to the Exchange Rate Agent (and the Trustee (or such
Paying Agent) will promptly thereafter give notice in the manner provided in Section 1.6 to the
affected Holders) specifying the Conversion Date. In the event the Company so determines that a
Conversion Event has occurred with respect to any currency unit in which Securities are denominated
or payable, the Company will promptly give written notice thereof to the Trustee (or any applicable
Paying Agent) and to the Exchange Rate Agent (and the Trustee (or such Paying Agent) will promptly
thereafter give notice in the manner provided in Section 1.6 to the affected Holders) specifying
the Conversion Date and the Specified Amount of each

34

 

Component Currency on the Conversion Date. In the event the Company determines in good faith
that any subsequent change in any Component Currency as set forth in the definition of Specified
Amount above has occurred, the Company will similarly give written notice to the Trustee (or any
applicable Paying Agent) and to the Exchange Rate Agent.

     The Trustee of the appropriate series of Securities shall be fully justified and protected in
relying and acting upon information received by it from the Company and the Exchange Rate Agent and
shall not otherwise have any duty or obligation to determine the accuracy or validity of such
information independent of the Company or the Exchange Rate Agent.

     Section 3.12. APPOINTMENT AND RESIGNATION OF EXCHANGE RATE AGENT. (a) Unless otherwise
specified pursuant to Section 3.1, if and so long as the Securities of any series (i) are
denominated in a currency or currency unit other than Dollars or (ii) may be payable in a currency
or currency unit other than Dollars, or so long as it is required under any other provision of this
Indenture, then the Company will maintain with respect to each such series of Securities, or as so
required, at least one Exchange Rate Agent. The Company will cause the Exchange Rate Agent to make
the necessary foreign exchange determinations at the time and in the manner specified pursuant to
Section 3.11 for the purpose of determining the applicable rate of exchange and, if applicable, for
the purpose of converting the issued currency or currencies or currency unit or units into the
applicable payment currency or currency unit for the payment of principal, premium, if any, and
interest, if any, pursuant to Section 3.11.

     (b) No resignation of the Exchange Rate Agent and no appointment of a successor Exchange Rate
Agent pursuant to this Section shall become effective until the acceptance of appointment by the
successor Exchange Rate Agent as evidenced by a written instrument delivered to the Company and the
Trustee of the appropriate series of Securities accepting such appointment executed by the
successor Exchange Rate Agent.

     (c) If the Exchange Rate Agent shall resign, be removed or become incapable of acting, or if a
vacancy shall occur in the office of the Exchange Rate Agent for any cause, with respect to the
Securities of one or more series, the Company shall promptly appoint a successor Exchange Rate
Agent or Exchange Rate Agents with respect to the Securities of that or those series (it being
understood that any such successor Exchange Rate Agent may be appointed with respect to the
Securities of one or more or all of such series and that, unless otherwise specified pursuant to
Section 3.1, at any time there shall only be one Exchange Rate Agent with respect to the Securities
of any particular series that are originally issued by the Company on the same date and that are
initially denominated and/or payable in the same currency or currencies or currency unit or units).

     Section 3.13. WIRE TRANSFERS. Notwithstanding any other provisions to the contrary in this
Indenture, the Company may make any payment of monies required to be deposited with the Trustee on
account of principal of, or premium, if any, or interest on, the Securities (whether pursuant to
optional or mandatory redemption payments, interest payment or otherwise) by wire transfer and
immediately available funds to an account designated by the Trustee on or before the date and time
such monies are to be paid to the Holders of the Security in accordance with the terms hereof.

35

 

     Section 3.14. CUSIP NUMBERS. The Company in issuing Securities may use “CUSIP” numbers (if
then generally in use), and if so, the Trustee may use the CUSIP numbers in notices of redemption
or exchange as a convenience to Holders; provided, however, that any such notice may state that no
representation is made as to the correctness or accuracy of the CUSIP number printed in the notice
or on the Securities, that reliance may be placed only on the other identification numbers printed
on the Securities, and any such redemption or exchange shall not be affected by any defect or
omission of such CUSIP numbers. The Company will promptly notify the Trustee of any change in
CUSIP numbers known to an Officer of the Company.

ARTICLE IV

SATISFACTION, DISCHARGE AND DEFEASANCE

     Section 4.1. TERMINATION OF COMPANY’S OBLIGATIONS UNDER THE INDENTURE. (a) This Indenture
shall upon Company Request cease to be of further effect with respect to Securities of or within
any series and any coupons appertaining thereto (except as to any surviving rights of registration
of transfer or exchange of such Securities and replacement of such Securities which may have been
lost, stolen or mutilated as herein expressly provided for) and the Trustee, at the expense of the
Company, shall execute proper instruments acknowledging satisfaction and discharge of this
Indenture with respect to such Securities and any coupons appertaining thereto when

     (1) either

     (A) all such Securities previously authenticated and delivered and all coupons appertaining
thereto (other than (i) such coupons appertaining to Bearer Securities surrendered in exchange for
Registered Securities and maturing after such exchange, surrender of which is not required or has
been waived as provided in Section 3.5, (ii) such Securities and coupons which have been destroyed,
lost or stolen and which have been replaced or paid as provided in Section 3.6, (iii) such coupons
appertaining to Bearer Securities called for redemption and maturing after the relevant Redemption
Date, surrender of which has been waived as provided in Section 10.6 and (iv) such Securities and
coupons 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 9.3) have been delivered to the Trustee for cancellation; or

     (B) all Securities of such series and, in the case of (i) or (ii) below, any coupons
appertaining thereto 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) if redeemable at the option of the Company, are to be called for redemption within one
year under arrangements satisfactory to the Trustee for giving of notice of redemption, and the
Company, in the case of (i), (ii) or (iii) above, has irrevocably deposited or caused to be
deposited with the Trustee as trust funds in trust for the purpose an amount in the currency or
currencies or currency unit or units in which the Securities of such series are

36

 

payable, sufficient to pay and discharge the entire indebtedness on such Securities and such
coupons not theretofore delivered to the Trustee for cancellation, for principal, premium, if any,
and interest, with respect thereto, 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 Company has paid or caused to be paid all other sums then payable hereunder by the
Company; and

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

     Notwithstanding the satisfaction and discharge of this Indenture, the obligation of the
Company to the Trustee and any predecessor Trustee under Section 6.8 and the obligations of the
Company to any Authenticating Agent under Section 6.13 shall survive until the Securities of the
discharged series have been paid in full, and, if money shall have been deposited with the Trustee
pursuant to subclause (B) of clause (1) of this Section, the obligations of the Trustee under
Section 4.2 and the last paragraph of Section 9.3 shall survive in accordance with the terms of
such Sections.

     Section 4.2. APPLICATION OF TRUST FUNDS. Subject to the provisions of the last paragraph of
Section 9.3, all money deposited with the Trustee pursuant to Section 4.1 shall be held in trust
and applied by it, in accordance with the provisions of the Securities, the coupons and this
Indenture, to the payment, either directly or through any Paying Agent (including the Company
acting as its own Paying Agent) as the Trustee may determine, to the Persons entitled thereto, of
the principal, premium, if any and any interest for whose payment such money has been deposited
with or received by the Trustee, but such money need not be segregated from other funds except to
the extent required by law.

     Section 4.3. APPLICABILITY OF DEFEASANCE PROVISIONS; COMPANY’S OPTION TO EFFECT DEFEASANCE OR
COVENANT DEFEASANCE. Unless pursuant to Section 3.1 provision is made to exclude with respect to
the Securities of a particular series either or both of (i) defeasance of the Securities of or
within such series under Section 4.4 or (ii) covenant defeasance of the Securities of or within
such series under Section 4.5, then, in addition to the rights of the Company pursuant to Section
4.1 above, the provisions of such Section or Sections, as the case may be, together with the
provisions of Sections 4.6 through 4.9 inclusive, with such modifications thereto as may be
specified pursuant to Section 3.1 with respect to any Securities of such series, shall be
applicable to such Securities and any coupons appertaining thereto, and the Company may at its
option, at any time, with respect to such Securities and any coupons appertaining thereto, elect to
have Section 4.4 (if applicable) or Section 4.5 (if applicable) be applied to such Outstanding
Securities and any coupons appertaining thereto upon compliance with the conditions set forth below
in this Article.

     Section 4.4. DEFEASANCE AND DISCHARGE. Upon the Company’s exercise of the option specified
in Section 4.3 applicable to this Section with respect to the Securities of or within a series, the
Company shall be deemed to have been discharged from its obligations with respect to such
Securities and any coupons appertaining thereto on the date the conditions set

37

 

forth in Section 4.6 are satisfied (hereinafter, a “defeasance”). For this purpose, such
defeasance means that the Company shall be deemed to have paid and discharged the entire
indebtedness represented by such Securities and any coupons appertaining thereto, which Securities
and coupons appertaining thereto shall thereafter be deemed to be “Outstanding” only for the
purposes of Section 4.7 and the other Sections of this Indenture referred to in clause (ii) of this
Section, and to have satisfied all its other obligations under such Securities and any coupons
appertaining thereto and this Indenture insofar as such Securities and any coupons appertaining
thereto are concerned (and the Trustee, at the expense of the Company, shall on Company Order
execute proper instruments acknowledging the same), except the following which shall survive until
otherwise terminated or discharged hereunder: (i) the rights of Holders of such Securities and any
coupons appertaining thereto to receive, solely from the trust funds described in Section 4.6(a)
and as more fully set forth in such Section, payments in respect of the principal of, premium, if
any, and interest, if any, on such Securities or any coupons appertaining thereto when such
payments are due; (ii) the Company’s obligations with respect to such Securities under Sections
3.5, 3.6, 9.2 and 9.3 and with respect to the payment of additional amounts, if any, payable with
respect to such Securities as specified pursuant to Section 3.1(b) (18); (iii) the rights, powers,
trusts, duties, immunities and indemnities of the Trustee hereunder and (iv) this Article IV.
Subject to compliance with this Article IV, the Company may exercise its option under this Section
notwithstanding the prior exercise of its option under Section 4.5 with respect to such Securities
and any coupons appertaining thereto. Following a defeasance, payment of such Securities may not
be accelerated because of an Event of Default.

     Section 4.5. COVENANT DEFEASANCE. Upon the Company’s exercise of the option specified in
Section 4.3 applicable to this Section with respect to any Securities of or within a series, the
Company shall be released from its obligations under Sections 7.1, 9.4 and 9.5, and, if specified
pursuant to Section 3.1, its obligations under any other covenant, with respect to such Securities
and any coupons appertaining thereto on and after the date the conditions set forth in Section 4.6
are satisfied (hereinafter, “covenant defeasance”), and such Securities and any coupons
appertaining thereto shall thereafter be deemed to be not “Outstanding” for the purposes of any
direction, waiver, consent or declaration or Act of Holders (and the consequences of any thereof)
in connection with Sections 7.1, 9.4 and 9.5, or such other specified covenant, and the operation
of Sections 5.1(3) and 5.1(6), but shall continue to be deemed “Outstanding” for all other purposes
hereunder. For this purpose, such covenant defeasance means that, with respect to such Securities
and any coupons appertaining thereto, the Company may omit to comply with and shall have no
liability in respect of any term, condition or limitation set forth in any such Section or such
other covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any
such Section or such other covenant or by reason of reference in any such Section or such other
covenant to any other provision herein or in any other document and such omission to comply shall
not constitute a Default or an Event of Default under Section 5.1(3) or 5.1(6) or otherwise, as the
case may be, but, except as specified above, the remainder of this Indenture and such Securities
and any coupons appertaining thereto shall be unaffected thereby.

     Section 4.6. CONDITIONS TO DEFEASANCE OR COVENANT DEFEASANCE. The following shall be the
conditions to application of Section 4.4 or Section 4.5 to any Securities of or within a series and
any coupons appertaining thereto:

38

 

     (a) The Company shall have deposited or caused to be deposited irrevocably with the Trustee
(or another trustee satisfying the requirements of Section 6.11 who shall agree to comply with, and
shall be entitled to the benefits of, the provisions of Sections 4.3 through 4.9 inclusive and the
last paragraph of Section 9.3 applicable to the Trustee, for purposes of such Sections also a
“Trustee”) as trust funds in trust for the purpose of making the payments referred to in clauses
(x) and (y) of this Section 4.6(a), with instructions to the Trustee as to the application thereof,
(A) money in an amount (in such currency, currencies or currency unit in which such Securities and
any coupons appertaining thereto are then specified as payable at Maturity), or (B) Government
Obligations 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 referred
to in clause (x) or (y) of this Section 4.6(a), money in an amount or (C) a combination thereof in
an amount, sufficient, in the determination of a nationally recognized independent accounting or
investment banking firm expressed in a written certification thereof delivered to the Trustee in
the case of clauses (B) or (C), to pay and discharge, and which shall be applied by the Trustee to
pay and discharge, (x) the principal of, premium, if any, and interest, if any, on such Securities
and any coupons appertaining thereto on the Maturity of such principal or installment of principal
or interest and (y) any mandatory sinking fund payments applicable to such Securities on the day on
which such payments are due and payable in accordance with the terms of this Indenture and such
Securities and any coupons appertaining thereto.

     Before such a deposit the Company may make arrangements satisfactory to the Trustee for the
redemption of Securities at a future date or dates in accordance with Article X which shall be
given effect in applying the foregoing.

     (b) The deposit pursuant to subsection (a) above shall not result in or constitute a Default
or Event of Default under this Indenture or result in a breach or violation of, or constitute a
default under, any other material agreement or instrument to which the Company is a party or by
which it is bound.

     (c) In the case of an election under Section 4.4, no Default or Event of Default under Section
5.1(4) or 5.1(5) with respect to such Securities and any coupons appertaining thereto shall have
occurred and be continuing during the period commencing on the date of such deposit and ending on
the 91st day after such date (it being understood that this condition shall not be deemed satisfied
until the expiration of such period).

     (d) In the case of an election under Section 4.4, the Company shall have delivered to the
Trustee an Officers’ Certificate and an Opinion of Counsel to the effect that (i) the Company has
received from, or there has been published by, the Internal Revenue Service a ruling, or (ii) since
the date of execution of this Indenture, there has been a change in the applicable Federal income
tax law, in either case to the effect that, and based thereon such opinion shall confirm that, the
Holders of such Securities and any coupons appertaining thereto will not recognize income, gain or
loss for Federal income tax purposes as a result of such defeasance and will be subject to Federal
income tax on the same amounts 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.

     (e) In the case of an election under Section 4.5, the Company shall have delivered to the
Trustee an Opinion of Counsel to the effect that the Holders of such Securities and any

39

 

coupons appertaining thereto will not recognize income, gain or loss for Federal income tax
purposes as a result of such covenant defeasance and will be subject to Federal income tax on the
same amounts, in the same manner and at the same times as would have been the case if such covenant
defeasance had not occurred.

     (f) The Company shall have delivered to the Trustee an Officers’ Certificate and an Opinion of
Counsel, each stating that all conditions precedent to the defeasance under Section 4.4 or the
covenant defeasance under Section 4.5 (as the case may be) have been complied with and an Opinion
of Counsel to the effect that either (i) as a result of a deposit pursuant to subsection (a) above
and the related exercise of the Company’s option under Section 4.4 or Section 4.5 (as the case may
be), registration is not required under the Investment Company Act of 1940, as amended, by the
Company, with respect to the trust funds representing such deposit or by the trustee for such trust
funds or (ii) all necessary registrations under said act have been effected.

     (g) Such defeasance or covenant defeasance shall be effected in compliance with any additional
or substitute terms, conditions or limitations which may be imposed on the Company in connection
therewith as contemplated by Section 3.1.

     Section 4.7. DEPOSITED MONEY AND GOVERNMENT OBLIGATIONS TO BE HELD IN TRUST. Subject to the
provisions of the last paragraph of Section 9.3, all money and Government Obligations (or other
property as may be provided pursuant to Section 3.1) (including the proceeds thereof) deposited
with the Trustee pursuant to Section 4.6 in respect of any Securities of any series and any coupons
appertaining thereto shall be held in trust and applied by the Trustee, in accordance with the
provisions of such Securities and any coupons appertaining thereto and this Indenture, to the
payment, either directly or through any Paying Agent (including the Company acting as its own
Paying Agent) as the Trustee may determine, to the Holders of such Securities and any coupons
appertaining thereto of all sums due and to become due thereon in respect of principal, premium, if
any, and interest, if any, but such money need not be segregated from other funds except to the
extent required by law.

     If specified with respect to any Security pursuant to Section 3.1, if, after a deposit
referred to in Section 4.6(a) has been made, (i) the Holder of a Security in respect of which such
deposit was made is entitled to, and does, elect pursuant to Section 3.11(b) or the terms of such
Security to receive payment in a currency or currency unit other than that in which the deposit
pursuant to Section 4.6(a) has been made in respect of such Security, or (ii) a Conversion Event
occurs as contemplated in Section 3.11(d) or 3.11(e) or by the terms of any Security in respect of
which the deposit pursuant to Section 4.6(a) has been made, the indebtedness represented by such
Security and any coupons appertaining thereto shall be deemed to have been, and will be, fully
discharged and satisfied through the payment of the principal of, premium, if any, and interest, if
any, on such Security as the same becomes due out of the proceeds yielded by converting (from time
to time as specified below in the case of any such election) the amount or other property deposited
in respect of such Security into the currency or currency unit in which such Security becomes
payable as a result of such election or Conversion Event based on the applicable Market Exchange
Rate for such currency or currency unit in effect on the second Business Day prior to each payment
date, except, with respect to a Conversion Event, for such currency or currency unit in effect (as
nearly as feasible) at the time of the Conversion Event.

40

 

     Section 4.8. REPAYMENT TO COMPANY. The Trustee (and any Paying Agent) shall promptly pay to
the Company upon Company Request any excess money or securities held by them at any time.

     Section 4.9. INDEMNITY FOR GOVERNMENT OBLIGATIONS. The Company shall pay, and shall
indemnify the Trustee against, any tax, fee or other charge imposed on or assessed against
Government Obligations deposited pursuant to this Article or the principal and interest received on
such Government Obligations, other than any such tax, fee or other charge that by law is for the
account of the Holders of the Securities subject to defeasance or covenant defeasance pursuant to
this Article.

ARTICLE V

DEFAULTS AND REMEDIES

     Section 5.1. EVENTS OF DEFAULT. An “Event of Default” occurs with respect to the Securities
of any series, except to the extent such event is specifically deleted or modified by the
applicable Board Resolutions or supplemental indenture as contemplated by Section 3.1 for the
Securities of such series, if (whatever the reason for such Event of Default and whether it shall
be voluntary or involuntary or be effected by operation of law or pursuant to any judgment, decree
or order of any court or any order, rule or regulation of any administrative or governmental body):

     (1) the Company defaults in the payment of interest on any Security of that series or any
coupon appertaining thereto or any additional amount payable with respect to any Security of that
series as specified pursuant to Section 3.1(b)(17) when the same becomes due and payable and such
default continues for a period of 30 days;

     (2) the Company defaults in the payment of the principal of or any premium on any Security of
that series when the same becomes due and payable at its Maturity or on redemption or otherwise, or
in the payment of a mandatory sinking fund payment when and as due by the terms of the Securities
of that series;

     (3) the Company defaults in the performance of, or breaches, any covenant or warranty of the
Company in this Indenture with respect to any Security of that series (other than a covenant or
warranty a default in whose performance or whose breach is elsewhere in this Section specifically
dealt with), and such default or breach continues for a period of 90 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 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;

     (4) the Company, pursuant to or within the meaning of any Bankruptcy Law, (A) commences a
voluntary case, (B) consents to the entry of an order for relief against it in an involuntary case,
(C) consents to the appointment of a Custodian of it or for all or substantially all of its
property, or (D) makes a general assignment for the benefit of its creditors;

41

 

     (5) a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that
(A) is for relief against the Company in an involuntary case, (B) appoints a Custodian of the
Company or for all or substantially all of its property, or (C) orders the liquidation of the
Company; and the order or decree remains unstayed and in effect for 90 days; or

     (6) any other Event of Default provided as contemplated by Section 3.1 with respect to
Securities of that series.

     The term “Bankruptcy Law” means Title 11, U.S. Code, or any similar federal or state law for
the relief of debtors. The term “Custodian” means any receiver, trustee, assignee, liquidator or
similar official under any Bankruptcy Law.

     Section 5.2. ACCELERATION; RESCISSION AND ANNULMENT. If an Event of Default with respect to
the Securities of any series at the time Outstanding occurs and is continuing, the Trustee or the
Holders of at least 25% in aggregate principal amount of all of the Outstanding Securities of that
series, by written notice to the Company (and, if given by the Holders, to the Trustee), may
declare the principal (or, if the Securities of that series are Original Issue Discount Securities
or Indexed Securities, such portion of the principal amount or other amount as may be specified in
the terms of that series) of all the Securities of that series to be due and payable and upon any
such declaration such principal (or, in the case of Original Issue Discount Securities or Indexed
Securities, such specified amount) shall be immediately due and payable.

     At any time after such a declaration of acceleration with respect to Securities of any series
has been made and before a judgment or decree for payment of the money due has been obtained by the
Trustee as hereinafter in this Article provided, the Holders of a majority in aggregate principal
amount of the Outstanding Securities of that series, by written notice to the Trustee, may rescind
and annul such declaration and its consequences if all existing Defaults and Events of Default with
respect to Securities of that series, other than the non-payment of the principal of Securities of
that series which have become due solely by such declaration of acceleration, have been cured or
waived as provided in Section 5.7. Upon any such rescission, the parties hereto shall be restored
respectively to their several positions and rights hereunder, and all rights, remedies and powers
of the parties hereto shall continue as though no acceleration had occurred.

     Section 5.3. COLLECTION OF INDEBTEDNESS AND SUITS FOR ENFORCEMENT BY TRUSTEE. The Company
covenants that if

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

     (2) default is made in the payment of the principal of (or premium, if any, on) any Security
of any series at the Maturity thereof and such default continues for a period of 10 days, the
Company will, upon demand of the Trustee, pay to it, for the benefit of the Holders of such
Securities or coupons, if any, the whole amount then due and payable on such Securities for
principal, premium, if any, and interest and, to the extent that payment of such interest shall be

42

 

legally enforceable, interest on any overdue principal, premium, if any, and on any overdue
interest, at the rate or rates prescribed therefor in such Securities or coupons.

     If the Company fails to pay such principal, premium, if any, and interest 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 such principal, premium, if any, and interest amounts so
due and unpaid, may prosecute such proceeding to judgment or final decree and may enforce the same
against the Company.

     In addition, if an Event of Default with respect to Securities of any series occurs and is
continuing, the Trustee may in its discretion proceed, in its own name and as trustee of an express
trust, 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 5.4. TRUSTEE MAY FILE PROOFS OF CLAIM. The Trustee may file such proofs of claim and
other papers or documents as may be necessary or advisable in order to have the claims of the
Trustee and the Holders of Securities allowed in any judicial proceedings relating to the Company,
its creditors or its property.

     Section 5.5. 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, in its own name and as trustee of an express trust, without the possession of any of the
Securities or the production thereof in any proceeding relating thereto.

     Section 5.6. DELAY OR OMISSION NOT WAIVER. No delay or omission by the Trustee or any Holder
of any Securities to exercise any right or remedy accruing upon an Event of Default shall impair
any such right or remedy or constitute a waiver of or acquiescence in any such Event of Default.

     Section 5.7. WAIVER OF PAST DEFAULTS. The Holders of a majority in aggregate principal
amount of Outstanding Securities of any series by notice to the Trustee may waive on behalf of the
Holders of all Securities of such series a past Default or Event of Default with respect to that
series and its consequences except a Default or Event of Default (i) in the payment of the
principal of, premium, if any, or interest on any Security of such series or any coupon
appertaining thereto or (ii) in respect of a covenant or provision hereof which pursuant to Section
8.2 cannot be amended or modified without the consent of the Holder of each Outstanding Security of
such series adversely affected. Upon any such waiver, such Default shall cease to exist, and any
Event of Default arising therefrom shall be deemed to have been cured, for every purpose of this
Indenture; but no such waiver shall extend to any subsequent or other Default or Event of Default
or impair any right consequent thereon. In case of any such waiver, the Company, the Trustee and
the Holders shall be restored to their former positions and rights hereunder and under the
Securities of such series, respectively.

43

 

     Section 5.8. CONTROL BY MAJORITY. The Holders of a majority in aggregate principal amount of
the Outstanding Securities of each series affected (with each such series voting as a class) 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 it with respect to
Securities of that series; provided, however, that (i) the Trustee may refuse to follow any
direction that conflicts with law or this Indenture, (ii) the Trustee may refuse to follow any
direction that is unduly prejudicial to the rights of the Holders of Securities of such series not
consenting, or that would in the good faith judgment of the Trustee have a substantial likelihood
of involving the Trustee in personal liability and (iii) the Trustee may take any other action
deemed proper by the Trustee which is not inconsistent with such direction.

     Section 5.9. LIMITATION ON SUITS BY HOLDERS. No Holder of any Security of any series or any
coupons appertaining thereto 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) the 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 at least 25% in aggregate principal amount of the Outstanding Securities of
that series have made a written request to the Trustee to institute proceedings in respect of such
Event of Default in its own name as Trustee hereunder;

     (3) such Holder or Holders have offered to the Trustee indemnity satisfactory to the Trustee
against any loss, liability or expense to be, or which may be, incurred by the Trustee in pursuing
the remedy;

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

     (5) during such 60 day period, the Holders of a majority in aggregate principal amount of the
Outstanding Securities of that series have not given to the Trustee a direction inconsistent with
such written request.

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

     Section 5.10. RIGHTS OF HOLDERS TO RECEIVE PAYMENT. Notwithstanding any other provision of
this Indenture, but subject to Section 9.2, the right of any Holder of a Security or coupon of any
series to receive payment of principal of, premium, if any, and, subject to Sections 3.5 and 3.7,
interest on the Security, on or after the respective due dates expressed in the Security (or, in
case of redemption, on the redemption dates), and the right of any Holder of a coupon to receive
payment of interest due as provided in such coupon, or to bring suit for the enforcement of any
such payment on or after such respective dates, shall not be impaired or affected without the
consent of such Holder.

44

 

     Section 5.11. APPLICATION OF MONEY COLLECTED. If the Trustee collects any money pursuant to
this Article, it shall pay out the money 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, 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 Trustee for amounts due under Section 6.8 in connection with such series of
Securities in respect of which money or other property is collected;

     Second: Subject to the terms of any subordination entered into as contemplated by Section
3.1(b) (27) hereof, to Holders of Securities of such series and coupons in respect of which or for
the benefit of which such money has been collected for amounts due and unpaid on such Securities
for principal of, premium, if any, and interest, ratably, without preference or priority of any
kind, according to the amounts due and payable on such Securities for principal, premium, if any,
and interest, respectively; and

     Third: The balance, if any, to the Company.

     The Trustee may fix a record date and payment date for any payment to Holders pursuant to this
Section 5.11. At least 15 days before such record date, the Trustee shall mail to each Holder and
the Company a notice that states the record date, the payment date and the amount to be paid.

     Unless otherwise specified in a supplemental indenture with respect to a series of Securities,
in any case where Securities are outstanding which are denominated in more than one currency, or in
a composite currency and at least one other currency, and the Trustee is directed to make ratable
payments under this Section to Holders of Securities, the Trustee shall calculate the amount of
such payments as follows: as of the day the Trustee collects an amount under this Article, the
Trustee shall, (i) as to each Holder of a Security to whom an amount is due and payable under this
Section which is denominated in a foreign currency or a composite currency, determine that amount
of Dollars that would be obtained for the amount owing such Holder, using the rate of exchange at
which in accordance with normal banking procedures the Trustee could purchase in Dollars as of such
day with such amount owing, (ii) calculate the sum of all Dollar amounts determined under (i) and
add thereto any amounts due and payable in Dollars; and (iii) using the individual amounts
determined in (i) or any individual amounts due and payable in Dollars, as the case may be, as a
numerator and the sum calculated in (ii) as a denominator, calculate as to each Holder of a
Security to whom an amount is owed under this Section the fraction of the amount collected under
this Article payable to such Holder. Any expenses incurred by the Trustee in actually converting
amounts owing Holders of Securities denominated in a currency or composite currency other than that
in which any amount is collected under this Article shall be likewise (in accordance with this
paragraph) be borne ratably by all Holders of Securities to whom amounts are payable under this
Section.

     Unless otherwise specified in the supplemental indenture with respect to a series of
Securities, to the fullest extent allowed under applicable law, if for the purpose of obtaining
judgment against the Company in any court it is necessary to convert the sum due in respect of the
principal of, or any premium or interest on the Securities of any series (the “Required

Currency”) into a currency in which judgment will be rendered (the “Judgment Currency”), the
rate of exchange used shall be the rate at which in accordance with normal banking procedures the
Trustee could purchase in The City of New York the Required Currency with the Judgment Currency on
the New York Business Day preceding that on which final judgment is given. The Company shall not
be liable for any shortfall in payments to Holders of Securities under this Section caused by a
change in exchange rates between the time the amount of a judgment against it is calculated as
above and the time the Trustee converts the Judgment Currency into the Required Currency to make
payments under this Section to Holders of Securities, but payment of such judgment shall discharge
all amounts owed by the Company on the claim or claims underlying such judgment.

     Section 5.12. RESTORATION OF RIGHTS AND REMEDIES. If the Trustee or any Holder has
instituted any proceeding to enforce any right or remedy under this Indenture and such proceeding
has been discontinued or abandoned for any reason, or has been determined adversely to the Trustee
or to such Holder, then and in every such case, subject to any determination in such proceeding,
the Company, the Trustee and the Holders shall be restored severally and respectively to their
former positions hereunder and thereafter all rights and remedies of the Trustee and the Holders
shall continue as though no such proceeding had been instituted.

     Section 5.13. RIGHTS AND REMEDIES CUMULATIVE. Except as otherwise provided in Section 5.9 or
with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities in
the last paragraph of Section 3.6, no right or remedy herein conferred upon or reserved to the
Trustee or 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.

THE TRUSTEE

     Section 6.1. RIGHTS OF TRUSTEE. Subject to the applicable provisions of the Trust Indenture
Act:

     (a) The Trustee may conclusively rely and shall be protected in acting or refraining from
acting upon any document believed by it to be genuine and to have been signed or presented by the
proper party or parties. The Trustee need not investigate any fact or matter stated in the
document, and may conclusively rely, in good faith, as to the truth of the statements and concerns
of the opinions expressed therein.

     (b) Any request or direction of the Company mentioned herein shall be sufficiently evidenced
by a Company Request or Company Order (other than delivery of any Security, together with any
coupons appertaining thereto, to the Trustee for authentication and delivery

46

 

pursuant to Section 3.3, which shall be sufficiently evidenced as provided therein) and any
resolution of the Board of Directors may be sufficiently evidenced by a Board Resolution.

     (c) Before the Trustee acts or refrains from acting, it may consult with counsel or require an
Officers’ Certificate. The Trustee shall not be liable for any action it takes or omits to take in
good faith in reliance on a Board Resolution, the written advice of counsel acceptable to the
Trustee, a certificate of an Officer or Officers delivered pursuant to Section 1.2, an Officers’
Certificate or an Opinion of Counsel.

     (d) The Trustee may act through agents or attorneys and shall not be responsible for the
misconduct or negligence of any agent or attorney appointed with due care.

     (e) The Trustee shall not be liable for any action it takes or omits to take in good faith
which it believes to be authorized or within its discretion or rights or powers.

     (f) The Trustee shall not be required 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 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.

     (g) Except during the continuance of an Event of Default, the Trustee undertakes to perform
such duties and only such duties as are specifically set forth in this Indenture, and no implied
covenants or obligations shall be read into this Indenture against the Trustee.

     (h) 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.

     (i) The Trustee shall not be liable with respect to any action taken or omitted to be taken by
it in good faith in accordance with the direction of the Holders of a majority in aggregate
principal amount of the Outstanding Securities (pursuant to Section 5.8) relating to the time,
method and place of conducting any proceeding for any remedy available to the Trustee, or
exercising any trust or power conferred upon the Trustee, under this Indenture.

     (j) 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 to examine the books, records and premises of the Company,
personally or by agent or attorney.

     (k) Any permissive right of the Trustee hereunder shall not be construed to be a duty.

     (l) The Trustee shall not be charged with knowledge of any Event of Default, other than as
described in Section 5.1(1) or (2), unless and except to the extent actually known by a Responsible
Officer of the Trustee or written notice thereof is received by the Trustee at its Corporate Trust
Office.

47

 

     Notwithstanding anything contained herein to the contrary, in case an Event of Default with
respect to the Securities of any series has occurred and is continuing, and is known to the
Trustee, the Trustee shall exercise, with respect to Securities of such series, such of the rights
and powers vested in it by this Indenture, and shall use the same degree of care and skill in their
exercise, as a prudent individual would exercise or use under the circumstances in the conduct of
his or her own affairs.

     Section 6.2. TRUSTEE MAY HOLD SECURITIES. The Trustee, any Paying Agent, any Registrar or
any other agent of the Company, in its individual or any other capacity, may become the owner or
pledgee of Securities and coupons and, subject to Sections 310(b) and 311 of the Trust Indenture
Act, may otherwise deal with the Company, an Affiliate or Subsidiary with the same rights it would
have if it were not Trustee, Paying Agent, Registrar or such other agent.

     Section 6.3. MONEY HELD IN TRUST. Subject to the provisions of Section 4.8 and the last
paragraph of Section 9.3, all moneys received by the Trustee shall, until used or applied as herein
provided, be held in trust for the purposes for which they were received, but need not be
segregated from other funds except to the extent required by law. The Trustee shall be under no
liability for investment of or interest on any money received by it hereunder except as otherwise
agreed with the Company. Except for amounts deposited pursuant to Article Four, so long as no
Event of Default shall have occurred and be continuing, all interest allowed on any such moneys
shall be paid from time to time to the Company upon a Company Order. Money held by the Trustee in
trust hereunder need not be segregated from other funds except to the extent required by law.

     Section 6.4. TRUSTEE’S DISCLAIMER. The recitals contained herein and in the Securities,
except the Trustee’s certificate of authentication, shall be taken as the statements of the
Company, and the Trustee assumes no responsibility for their correctness. The Trustee makes no
representation as to the validity or adequacy of this Indenture or the Securities or any coupon,
except that the Trustee represents and warrants that it is duly authorized to execute and deliver
this Indenture, authenticate the Securities and perform its obligations hereunder and thereunder;
that the statements made by it in a Statement of Eligibility and Qualification on Form T-1 supplied
or to be supplied to the Company in connection with the registration of any Securities are and at
the time of delivery will be true and accurate; and that such Statement complies and at the time of
delivery will comply with the requirements of the Trust Indenture Act and the Securities Act, in
each case, applicable to such Statement. The Trustee shall not be accountable for the Company’s
use of the proceeds from the Securities or for monies paid over to the Company pursuant to the
Indenture.

     Section 6.5. NOTICE OF DEFAULTS. If a Default occurs and is continuing with respect to the
Securities of any series and if it is known to a Responsible Officer of the Trustee, the Trustee
shall, within 90 days after it occurs, transmit, in the manner and to the extent provided in
Section 313(c) of the Trust Indenture Act, notice of all uncured Defaults known to it; provided,
however, that, except in the case of a Default in payment on the Securities of any series, the
Trustee may withhold the notice if and so long as a Responsible Officer in good faith determines
that withholding such notice is in the interests of Holders of Securities of that series; provided,
further, that in the case of any default or breach of the character specified in Section

48

 

5.1(3) with respect to the Securities and coupons of such series, no such notice to Holders
shall be given until at least 90 days after the occurrence thereof.

     Section 6.6. REPORTS BY TRUSTEE TO HOLDERS. (a) Within 60 days after each May 15 of each
year commencing with the first May 15 after the first issuance of Securities pursuant to this
Indenture, the Trustee shall transmit by mail to all Holders of Securities as provided in Section
313(c) of the Trust Indenture Act a brief report dated as of such May 15 if required by and in
compliance with Section 313(a) of the Trust Indenture Act. A copy of each report shall, at the
time of such transmission to Holders, be filed by the Trustee with each stock exchange, if any,
upon which the Securities are listed, with the Commission and with the Company. The Company will
promptly notify the Trustee when the Securities are listed on any stock exchange and of any
delisting thereof.

     (b) The Trustee shall from time to time transmit by mail to all Holders of Securities as
provided in Section 313(c) of the Trust Indenture Act, such reports as are required to be filed
pursuant to Section 313(b) of the Trust Indenture Act.

     Section 6.7. SECURITY HOLDER LISTS. The Trustee shall preserve in as current a form as is
reasonably practicable the most recent list available to it of the names and addresses of Holders
of Securities of each series. If the Trustee is not the Registrar, the Company shall furnish to
the Trustee semiannually on or before the last day of June and December in each year, and at such
other times as the Trustee may request in writing, a list, in such form and as of such date as the
Trustee may reasonably require, containing all the information in the possession or control of the
Registrar, the Company or any of its Paying Agents other than the Trustee as to the names and
addresses of Holders of Securities of each such series. If there are Bearer Securities of any
series Outstanding, even if the Trustee is the Registrar, the Company shall furnish to the Trustee
such a list containing such information with respect to Holders of such Bearer Securities only.

     Section 6.8. COMPENSATION AND INDEMNITY. (a) The Company shall pay to the Trustee from time
to time such reasonable compensation for its services as the Company and the Trustee may agree in
writing from time to time. The Trustee’s compensation shall not be limited by any law on
compensation of a trustee of an express trust. The Company shall reimburse the Trustee upon
request for all reasonable expenses, disbursements and advances incurred by it in connection with
the performance of its duties under this Indenture, except any such expense, disbursement or
advance as may be attributable to its negligence or bad faith. Such expenses shall include the
reasonable compensation and expenses of the Trustee’s agents and counsel.

     (b) The Company shall indemnify the Trustee for, and hold it harmless against, any and all
loss, liability, damage, claim or expense (including attorneys fees and expenses, and including
taxes other than taxes based upon, measured by or determined by the income of the Trustee),
including without limitation the costs and expenses of defending itself against any third-party
claim (whether asserted by any Holder or any other Person (other than the Company to the extent of
any claim brought by it against the Trustee that establishes a breach by the Trustee in the
observance or performance of its duties under this Indenture)), incurred by it without negligence,
willful misconduct or bad faith arising out of or in connection with its acceptance or
administration of the trust or trusts hereunder, including the performance of its

49

 

duties or the exercise of its powers hereunder (collectively, “Claims”). The Trustee shall
notify the Company promptly of any Claim (other than Claims made by the Company against the
Trustee) for which it may seek indemnity. The Company may elect to defend the Claim and, in such
case, the Trustee shall cooperate in the defense. The Trustee may have separate counsel and the
Company shall pay the reasonable fees and expenses of such counsel. The Company need not pay for
any settlement made without its consent.

     (c) The Company need not reimburse any expense, disbursement or advance or indemnify against
any Claim incurred by the Trustee through negligence, willful misconduct or bad faith on the part
of the Trustee.

     (d) To secure the payment obligations of the Company pursuant to this Section, the Trustee
shall have a lien prior to the Securities of any series on all money or property held or collected
by the Trustee, except that held in trust to pay principal, premium, if any, and interest on
particular Securities.

     (e) When the Trustee incurs expenses or renders services in connection with an Event of
Default specified in Section 5.1(4) or Section 5.1(5), 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.

     (f) The provisions of this Section shall survive the termination of this Indenture.

     (g) The protections, agreements and indemnities afforded to the Trustee under this Section
shall include any other agency to which it may be appointed or with respect to which it may serve
hereunder, or in respect of any Securities under any related Board Resolution or supplemental
indenture, including but not limited to registrar, paying agent, conversion agent or calculation
agent.

     Section 6.9. SEPARATE TRUSTEE; REPLACEMENT OF TRUSTEE. (a) The Company may, but need not,
appoint a separate Trustee for any one or more series of Securities. The resignation or removal of
the Trustee and the appointment of a successor Trustee shall become effective only upon the
successor Trustee’s acceptance of appointment as provided in Section 6.10. In the event of an
appointment of a separate Trustee for any one or more series of Securities, the allocation of
responsibilities between the separate Trustees shall be determined at that time.

     (b) The Trustee may resign at any time with respect to the Securities of any one or more
series by giving written notice thereof to the Company. If the instrument of acceptance by a
successor Trustee required by Section 6.10 shall not have been delivered to the Trustee within 30
days after the giving of such notice of resignation, the resigning Trustee may petition any court
of competent jurisdiction for the appointment of a successor Trustee with respect to the Securities
of such series.

     (c) The Holders of a majority in aggregate principal amount of the Outstanding Securities of
any series may remove the Trustee with respect to any one or more series by so

50

 

notifying the Trustee and the Company in writing and may appoint a successor Trustee for such
series with the Company’s consent.

     If an instrument of acceptance by a successor Trustee required by Section 6.10 shall not have
been delivered to the Trustee within 30 days after the giving of such notice of removal, the
Trustee being removed may petition any court of competent jurisdiction for the appointment of a
successor Trustee with respect to the Securities of such series.

     (d) If at any time:

     (1) the Trustee fails to comply with Section 310(b) of the Trust Indenture Act after written
request therefor by the Company or by any Holder who has been a bona fide Holder of a Security for
at least six months, or

     (2) the Trustee shall cease to be eligible under Section 6.11 hereof or Section 310(a) of the
Trust Indenture Act and shall fail to resign after written request therefor by the Company or by
any Holder of a Security who has been a bona fide Holder of a Security for at least six months; or

     (3) the Trustee becomes incapable of acting, is adjudged a bankrupt or an insolvent or a
receiver or public officer takes charge of the Trustee or its property or affairs for the purpose
of rehabilitation, conservation or liquidation, then, in any such case, (i) the Company may remove
the Trustee with respect to all Securities, or (ii) subject to Section 315(e) of the Trust
Indenture Act, any Holder who has been a bona fide Holder of a Security for at least six months
may, on behalf of himself and all others similarly situated, petition any court of competent
jurisdiction for the removal of the Trustee with respect to all Securities and the appointment of a
successor Trustee or Trustees.

     (e) If the Trustee resigns or is removed or becomes incapable of acting or if a vacancy exists
in the office of Trustee for any reason, with respect to Securities of one or more series, the
Company shall promptly appoint a successor Trustee with respect to the Securities of that or those
series (it being understood that any such successor Trustee may be appointed with respect to the
Securities of one or more or all of such series and that at any time there shall be only one
Trustee with respect to the Securities of any particular series) and shall comply with the
applicable requirements of Section 6.10. If, within one year after such resignation, removal or
incapability, or the occurrence of such vacancy, a successor Trustee with respect to the Securities
of any series shall be appointed by Act of the Holders of a majority in principal amount of the
Outstanding Securities of such series delivered to the Company and the retiring Trustee, the
successor Trustee so appointed shall, forthwith upon its acceptance of such appointment in
accordance with the applicable requirements of Section 6.10, become the successor Trustee with
respect to the Securities of such series and to that extent supersede the successor Trustee
appointed by the Company. If no successor Trustee with respect to the Securities of any series
shall have been so appointed by the Company or the Holders and accepted appointment in the manner
required by Section 6.10, then, subject to Section 315(e) of the Trust Indenture Act, 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.

51

 

     Section 6.10. ACCEPTANCE OF APPOINTMENT BY SUCCESSOR. (a) In case of the appointment
hereunder of a successor Trustee with respect to all Securities, every such successor Trustee shall
execute, acknowledge and deliver to the Company and to the retiring Trustee an instrument accepting
such appointment. Thereupon, the resignation or removal of the retiring Trustee shall become
effective, and the successor Trustee, without further act, deed or conveyance, shall become vested
with all the rights, powers and duties of the retiring Trustee; but, on the request of the Company
or the successor Trustee, such retiring Trustee shall, upon payment of its charges, execute and
deliver an instrument transferring to such successor Trustee all the rights, powers and trusts of
the retiring Trustee and shall duly assign, transfer and deliver to such successor Trustee all
property and money held by such retiring Trustee hereunder.

     (b) In case of the appointment hereunder of a successor Trustee with respect to the Securities
of one or more (but not all) series, the Company, the retiring Trustee and such successor Trustee
shall execute and deliver an indenture supplemental hereto wherein such successor Trustee shall
accept such appointment and which (i) shall contain such provisions as shall be necessary or
desirable to transfer and confirm to, and to vest in, such 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, (ii) 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 (iii) shall add to or change
any of the provisions of this Indenture as shall be necessary to provide for or facilitate the
administration of the trusts hereunder by more than one Trustee, it being understood that nothing
herein or in such supplemental indenture shall constitute such Trustees co-trustees of the same
trust and that each such Trustee shall be trustee of a trust or trusts hereunder separate and apart
from any trust or trusts hereunder administered by any other such Trustee and upon the execution
and delivery of such supplemental indenture the resignation or removal of the retiring Trustee
shall become effective to the extent provided therein and each such successor Trustee, without any
further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties
of the retiring Trustee with respect to the Securities of that or those series to which the
appointment of such successor Trustee relates; but, on request of the Company or any successor
Trustee, such retiring Trustee shall duly assign, transfer and deliver to such successor Trustee
all property and money held by such retiring Trustee hereunder with respect to the Securities of
that or those series to which the appointment of such successor Trustee relates.

     (c) No successor Trustee shall accept its appointment unless at the time of such acceptance
such successor Trustee shall be qualified and eligible under the Trust Indenture Act.

     (d) The Company shall give, or cause to be given, notice of each resignation and each removal
of the Trustee with respect to the Securities of any series and each appointment of a successor
Trustee with respect to the Securities of any series in the manner provided for notices to the
Holders of Securities in Section 1.6. Each notice shall include the name of the successor Trustee
with respect to the Securities of such series and the address of its Corporate Trust Office.

     Section 6.11. ELIGIBILITY; DISQUALIFICATION. There shall at all times be a Trustee hereunder
with respect to each series of Securities (which need not be the same Trustee

52

 

for all series). Each Trustee hereunder shall be eligible to act as trustee under Section
310(a)(1) of the Trust Indenture Act and shall have a combined capital and surplus of at least
$100,000,000. If such corporation publishes reports of condition at least annually, pursuant to
law or the requirements of federal, state, territorial or District of Columbia 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 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.

     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.

     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 or acquiring all or substantially all of the corporate
trust business of the Trustee, shall be the successor of the Trustee hereunder, provided such
corporation shall be otherwise qualified and eligible under this Article, without the execution or
filing of any paper or any further act on the part of any of the parties hereto. In case any
Securities shall have been authenticated, but not delivered, by the Trustee then in office, any
successor by merger, conversion or consolidation to, or by succession to or acquisition of all or
substantially all of the corporate trust business of, 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. APPOINTMENT OF AUTHENTICATING AGENT. The Trustee may appoint an Authenticating
Agent or Agents with respect to one or more series of Securities which shall be authorized to act
on behalf of the Trustee to authenticate Securities of such series issued upon original issue
exchange, registration of transfer or partial redemption thereof, and Securities so authenticated
shall be entitled to the benefits of this Indenture and shall be valid and obligatory for all
purposes as if authenticated by the Trustee hereunder. Any such appointment shall be evidenced by
an instrument in writing signed by a Responsible Officer of the Trustee, a copy of which instrument
shall be promptly furnished to the Company. Wherever reference is made in this Indenture to the
authentication and delivery of Securities by the Trustee or the Trustee’s certificate of
authentication, such reference shall be deemed to include authentication and delivery on behalf of
the Trustee by an Authenticating Agent and a certificate of authentication executed on behalf of
the Trustee by an Authenticating Agent. Each Authenticating Agent shall be acceptable to the
Company and, except as may otherwise be provided pursuant to Section 3.1, shall at all times be a
bank or trust company or corporation organized and doing business and in good standing under the
laws of the United States of America or of any State or the District of Columbia, authorized under
such laws to act as Authenticating Agent, having a combined capital and surplus of not less than
$1,500,000 and subject to supervision or examination by Federal or State authorities. If such
Authenticating Agent publishes reports of condition at least annually, pursuant to law or the
requirements of the aforesaid supervising or examining authority, then for the purposes of this
Section, the combined

53

 

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. In case 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 or acquiring the
corporate agency or corporate trust business of an Authenticating Agent, shall continue to be an
Authenticating Agent, provided such corporation shall be otherwise eligible under this Section,
without the execution or filing of any paper or further act on the part of the Trustee or the
Authenticating Agent.

     An Authenticating Agent for any series of Securities may at any time resign by giving written
notice of resignation to the Trustee for such series and to the Company. The Trustee for any
series of Securities may at any time terminate the agency of an Authenticating Agent by giving
written notice of termination to such Authenticating Agent and to the Company. Upon receiving such
a notice of resignation or upon such a termination, or in case at any time such Authenticating
Agent shall cease to be eligible in accordance with the provisions of this Section, the Trustee for
such series may appoint a successor Authenticating Agent which shall be acceptable to the Company
and shall give notice of such appointment to all Holders of Securities of the series with respect
to which such Authenticating Agent will serve in the manner set forth in Section 1.6. 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 herein. 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 such reasonable
compensation as the Company and such Authenticating Agent agree in writing from time to time
including reimbursement of its reasonable expenses 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 or in lieu of the Trustee’s
certificate of authentication, an alternate certificate of authentication substantially in the
following form:

     This is one of the [Securities] [of the series designated herein and] referred to in the
within-mentioned Indenture.

	 	 	 	 	 
	 	[____________],

of the Holders of Securities of such series and any related coupons or any other series of
Securities in any material respect; or

     (9) to establish the form or terms of Securities of any series as permitted by Sections 2.1
and 3.1; or

     (10) to provide for the delivery of indentures supplemental hereto or the Securities of any
series in or by means of any computerized, electronic or other medium, including without limitation
by computer diskette; or

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

     (12) if allowed without penalty under applicable laws and regulations, to permit payment in
the United States (including any of the states and the District of Columbia), its territories, its
possessions and other areas subject to its jurisdiction of principal, premium, if any, or interest,
if any, on Bearer Securities or coupons, if any; or

     (13) to correct or supplement any provision herein which may be inconsistent with any other
provision herein or to cure any ambiguity or omission or to correct any mistake; or

     (14) to make any other provisions with respect to matters or questions arising under this
Indenture, provided such action shall not adversely affect the interests of the Holders of
Securities of any series in any material respect.

     Section 8.2. WITH CONSENT OF HOLDERS. Without prior notice to any Holder but with the
written consent of the Holders of a majority of the aggregate principal amount of the Outstanding
Securities of each series adversely affected by such supplemental indenture (with the Securities of
each series voting as a class), the Company and the Trustee may enter into an indenture or
indentures supplemental hereto to add any provisions to or to change or eliminate any provisions of
this Indenture or of any other indenture supplemental hereto or to modify the rights of the Holders
of Securities of each such series; provided, however, that without the consent of the Holder of
each Outstanding Security adversely affected thereby, a supplemental indenture under this Section
may not:

     (1) change the Stated Maturity of the principal of, or any installment of principal of or
interest on, any Security, or reduce the principal amount thereof or the rate of interest thereon
or any premium payable upon the redemption thereof, or reduce the amount of the principal of an
Original Issue Discount Security or Indexed Security that would be due and payable upon a
declaration of acceleration of the Maturity thereof pursuant to Section 5.2, or change any Place of
Payment where, or the coin or currency in which any Securities or any premium or the interest
thereon is payable, or impair the right to institute suit for the enforcement of any such payment
on or after the Stated Maturity thereof (or, in the case of redemption, on or after the Redemption
Date);

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

     (3) except to the extent provided in Section 8.1(11), make any change in Section 5.7 or this
8.2 except to increase any percentage or to provide that certain other provisions of this Indenture
cannot be modified or waived except with the consent of the Holders of each Outstanding Security
affected thereby, provided, however, that this clause shall not be deemed to require the consent of
any Holders with respect to changes in the references to the “Trustee” and concomitant changes in
this Section, in accordance with the requirements of Sections 6.10(b) and 8.1(11); or

     (4) modify the ranking or priority of the Securities.

     For the purposes of this Section 8.2, if the Securities of any series are issuable upon the
exercise of warrants, any holder of an unexercised and unexpired warrant with respect to such
series shall not be deemed to be a Holder of Outstanding Securities of such series in the amount
issuable upon the exercise of such warrants.

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

57

 

     It is not necessary under this Section 8.2 for the Holders to consent to the particular form
of any proposed supplemental indenture, but it is sufficient if they consent to the substance
thereof.

     Section 8.3. COMPLIANCE WITH TRUST INDENTURE ACT. Every amendment to this Indenture or the
Securities of one or more series shall be set forth in a supplemental indenture that complies with
the Trust Indenture Act as then in effect.

     Section 8.4. EXECUTION OF SUPPLEMENTAL INDENTURES. In executing, or accepting the additional
trusts created by, any supplemental indenture permitted by this Article or the modification thereby
of the trusts created by this Indenture, the Trustee shall be entitled to receive, and shall be
fully protected in relying upon, an Opinion of Counsel stating that the execution of such
supplemental indenture is authorized or permitted by this Indenture. The Trustee may, but shall
not be obligated to, enter into any such supplemental indenture which adversely affects the
Trustee’s own rights, duties or immunities under this Indenture or otherwise. The Trustee shall
enter into any such supplemental indenture presented to it by the Company in compliance with this
Article 8 if such supplemental indenture does not adversely affect the Trustee’s own rights, duties
or immunities under this Indenture or otherwise. In formulating its opinion on such matters the
Trustee shall be entitled to rely on such evidence as it deems appropriate, which may be or
include, without limitation, reliance solely on an opinion or advice of its counsel.

     Section 8.5. EFFECT OF SUPPLEMENTAL INDENTURES. Upon the execution of any supplemental
indenture under this Article, this Indenture shall be modified in accordance therewith, and such
supplemental indenture shall form a part of this Indenture for all purposes; and every Holder of
Securities theretofore or thereafter authenticated and delivered hereunder and of any coupon
appertaining thereto shall be bound thereby; provided that if such supplemental indenture makes any
of the changes described in clauses (1) through (4) of the first proviso to Section 8.2, such
supplemental indenture shall bind each Holder of a Security who has consented to it and every
subsequent Holder of such Security or any part thereof.

     Section 8.6. REFERENCE IN SECURITIES TO SUPPLEMENTAL INDENTURES. Securities, including any
coupons, of any series authenticated and delivered after the execution of any supplemental
indenture pursuant to this Article may, and shall if required by the Trustee, bear a notation in
form approved by the Trustee as to any matter provided for in such supplemental indenture. If the
Company shall so determine, new Securities including any coupons of any series so modified as to
conform, in the opinion of the Trustee and the Company, to any such supplemental indenture may be
prepared and executed by the Company and authenticated and delivered by the Trustee in exchange for
Outstanding Securities including any coupons of such series.

ARTICLE IX

COVENANTS

     Section 9.1. PAYMENT OF PRINCIPAL, PREMIUM, IF ANY, AND INTEREST. The Company covenants and
agrees for the benefit of the Holders of each series of Securities that it

58

 

will duly and punctually pay the principal of, premium, if any, and interest on the Securities
of that series in accordance with the terms of the Securities of such series, any coupons
appertaining thereto and this Indenture. An installment of principal, premium, if any, or interest
shall be considered paid on the date it is due if the Trustee or Paying Agent holds on that date
money designated for and sufficient to pay the installment.

     Section 9.2. MAINTENANCE OF OFFICE OR AGENCY. If Securities of a series are issued as
Registered Securities, the Company will maintain in each Place of Payment for any series of
Securities an office or agency where Securities of that series may be presented or surrendered for
payment, where Securities of that series may be surrendered for registration of transfer or
exchange and where notices and demands to or upon the Company in respect of the Securities of that
series and this Indenture may be served. If Securities of a series are issuable as Bearer
Securities, the Company will maintain, (i) subject to any laws or regulations applicable thereto,
an office or agency in a Place of Payment for that series which is located outside the United
States, where Securities of that series and related coupons may be presented and surrendered for
payment; provided, however, that if the Securities of that series are listed on The International
Stock Exchange of the United Kingdom and the Republic of Ireland Limited, the Luxembourg Stock
Exchange or any other stock exchange located outside the United States and such stock exchange
shall so require, the Company will maintain a Paying Agent for the Securities of that series in
London, Luxembourg or any other required city located outside the United States, as the case may
be, so long as the Securities of that series are listed on such exchange, and (ii) subject to any
laws or regulations applicable thereto, an office or agency in a Place of Payment for that series
which is located outside the United States where Securities of that series may be surrendered for
exchange and where notices and demands to or upon the Company in respect of the Securities of that
series and this Indenture may be served. The Company will give prompt written notice to the
Trustee of the location, and any change in the location, of any such office or agency. If at any
time the Company shall fail to maintain any such required office or agency or shall fail to furnish
the Trustee with the address thereof, such presentations, surrenders, notices and demands may be
made or served at the Corporate Trust Office of the Trustee, except that Bearer Securities of that
series and the related coupons unless otherwise specified in the Supplemental Indenture for such
Series, may be presented and surrendered for payment and conversion at the offices specified in the
Security, in London, England, and the Company hereby appoints the Trustee as its agent to receive
all such presentations, surrenders, notices and demands (provided, however, that the foregoing
appointment shall not impose or imply any obligation on the part of the Trustee to maintain any
office for any such purposes other than the Corporate Trust Office.)

     Unless otherwise specified as contemplated by Section 3.1, no payment of principal, premium or
interest on Bearer Securities shall be made at any office or agency of the Company in the United
States, by check mailed to any address in the United States, by transfer to an account located in
the United States or upon presentation or surrender in the United States of a Bearer Security or
coupon for payment, even if the payment would be credited to an account located outside the United
States; provided, however, that, if the Securities of a series are denominated and payable in
Dollars, payment of principal of and any premium or interest on any such Bearer Security shall be
made at an office of a Paying Agent of the Company in the Borough of Manhattan, The City of New
York, if (but only if) payment in Dollars of the full amount of such principal, premium or
interest, as the case may be, at all offices or agencies

59

 

outside the United States maintained for the purpose by the Company in accordance with this
Indenture is illegal or effectively precluded by exchange controls or other similar restrictions.

     Subject to the preceding paragraphs, the Company may also from time to time designate one or
more other offices or agencies where the Securities (including any coupons, if any) 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 Company of its obligation to maintain an office or agency in each Place of
Payment for Securities (including any coupons, if any) of any series for such purposes. The
Company will give prompt written notice to the Trustee of any such designation or rescission and of
any change in the location of any such other office or agency.

     Unless otherwise specified as contemplated by Section 3.1, the Trustee shall initially serve
as Paying Agent. The Paying Agent may make reasonable rules not inconsistent herewith for the
performance of its functions.

     Section 9.3. MONEY FOR SECURITIES TO BE HELD IN TRUST; UNCLAIMED MONEY. If the Company shall
at any time act as its own Paying Agent with respect to any series of Securities, it will, on or
before each due date of the principal of, premium, if any, or interest on any of the Securities of
that series, segregate and hold in trust for the benefit of the Persons entitled thereto a sum
sufficient to pay the principal, premium, if any, or interest so becoming due until such sums shall
be paid to such Persons or otherwise disposed of as herein provided and will promptly notify the
Trustee in writing of any 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 of or any premium or interest on any Securities
of that series, deposit with a Paying Agent a sum sufficient to pay such amount, such sum to be
held as provided by the Trust Indenture Act, and (unless such Paying Agent is the Trustee) the
Company will promptly notify the Trustee of any failure so to act.

     If the Company is not acting as its own Paying Agent, the Company will cause each Paying Agent
for any series of Securities other than the Trustee to execute and deliver to the Trustee an
instrument in which such Paying Agent shall agree with the Trustee, subject to the provisions of
this Section, that such Paying Agent will:

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

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

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

     Notwithstanding anything in this Section 9.3 to the contrary, the Company may at any time, for
the purpose of obtaining the satisfaction and discharge of this Indenture, or with respect

60

 

to one or more 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,
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.

     Subject to applicable abandoned property laws, any money deposited with the Trustee or any
Paying Agent, or then held by the Company, in trust for the payment of any principal, premium or
interest or other amounts on any Security of any series and remaining unclaimed for two years after
such principal, premium, if any, or interest or other amounts has become due and payable shall be
paid to the Company (including interest income on such funds, if any), or (if then held by the
Company) shall be discharged from such trust; and the Holder of such Security and coupon, if any,
shall thereafter, as an unsecured general creditor, look only to the Company for payment thereof,
and all liability of the Trustee or such Paying Agent with respect to such trust money, and all
liability of the Company as trustee thereof, shall thereupon cease.

     Section 9.4. CORPORATE EXISTENCE. Subject to Article VII, the Company will at all times do or
cause to be done all things necessary to preserve and keep in full force and effect its corporate
existence.

     Section 9.5. REPORTS BY THE COMPANY. The Company covenants, at any time at which there are
Outstanding Securities of any series issued under this Indenture:

     (a) to file with the Trustee, within 30 days after the Company is required to file the same
with the Commission, copies of the annual reports and of the information, documents and other
reports (or copies of such portions of any of the foregoing as the Commission may from time to time
by rules and regulations prescribe) which the Company may be required to file with the Commission
pursuant to section 13 or section 15(d) of the Securities Exchange Act of 1934, as amended; or, if
the Company is not required to file information, documents or reports pursuant to either of such
sections, then to file with the Trustee and the Commission, in accordance with rules and
regulations prescribed from time to time by the Commission, such of the supplementary and periodic
information, documents and reports which may be required pursuant to section 13 of the Securities
Exchange Act of 1934, as amended, in respect of a security listed and registered on a national
securities exchange as may be prescribed from time to time in such rules and regulations;

     (b) to file with the Trustee and the Commission, in accordance with the rules and regulations
prescribed from time to time by the Commission, such additional information, documents and reports
with respect to compliance by the Company with the conditions and covenants provided for in this
Indenture, as may be required from time to time by such rules and regulations; and

     (c) to transmit to all Holders of Securities within 30 days after the filing thereof with the
Trustee, in the manner and to the extent provided in section 313(c) of the Trust Indenture Act,
such summaries of any information, documents and reports required to be filed by the

61

 

Company pursuant to subsections (a) and (b) of this Section 9.6, as may be required by rules
and regulations prescribed from time to time by the Commission.

     Section 9.6. ANNUAL REVIEW CERTIFICATE. At any time at which there are Outstanding Securities
of any series issued under this Indenture, the Company covenants and agrees to deliver to the
Trustee, within 120 days after the end of each fiscal year of the Company, a brief certificate from
the principal executive officer, principal financial officer, or principal accounting officer as to
his or her knowledge of whether the Company is in Default under this Indenture. For purposes of
this Section 9.7, such compliance shall be determined without regard to any period of grace or
requirement of notice provided under this Indenture.

     Section 9.7.
WAIVER OF CERTAIN COVENANTS Section 9.8. . The Company may omit in any particular
instance to comply with any term, provision or condition as specified pursuant to Section
3.1(b)(17) for Securities of any series, in any covenants of the Company added to Article IX
pursuant to Section 3.1(b)(16) or Section 3.1(b)(17) in connection with Securities of a series, if
before or after the time for such compliance the Holders of at least a majority in principal amount
of all outstanding Securities, by act of such Holders, waive such compliance in such instance or
generally waive compliance with such term, provision or condition, but no such waiver shall extend
to or affect such term, provision or condition except to the extent so expressly waived, and, until
such waiver shall become effective, the obligations of the Company and the duties of the Trustee in
respect of any such term, provision or condition shall remain in full force and effect.

ARTICLE X

REDEMPTION

     Section 10.1. APPLICABILITY OF ARTICLE. Securities (including coupons, if any) of or within
any series which are redeemable in whole or in part before their Stated Maturity shall be
redeemable in accordance with their terms and (except as otherwise specified in the applicable
Board Resolution or supplemental indenture with respect to such Series of Securities, as
contemplated by Section 3.1 for Securities of any series) in accordance with this Article.

     Section 10.2. ELECTION TO REDEEM; NOTICE TO TRUSTEE. The election of the Company to redeem
any Securities, including coupons, if any, shall be evidenced by a Board Resolution. In the case
of any redemption at the election of the Company of less than all the Securities or coupons, if
any, of any series of the same tenor, the Company shall, at least 60 days (45 days in the case of
redemption of all Securities of any series or of any series with the same (i) Stated Maturity, (ii)
period or periods within which, price or prices at which and terms and conditions upon which such
Securities may or shall be redeemed or purchased, in whole or in part, at the option of the Company
or pursuant to any sinking fund or analogous provision or repayable at the option of the Holder and
(iii) rate or rates at which the Securities bear interest, if any, or formula pursuant to which
such rate or rates accrue (collectively, the “Equivalent Principal Terms”)) prior to the Redemption
Date fixed by the Company (unless a shorter notice shall be satisfactory to the Trustee), notify
the Trustee of such Redemption Date 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 (i) prior to the expiration

62

 

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

     Section 10.3. SELECTION OF SECURITIES TO BE REDEEMED. If less than all the Securities with
Equivalent Principal Terms of any series are to be redeemed (unless all of the Securities of such
series and of a specified tenor are to be redeemed), the particular Securities to be redeemed shall
be selected not more than 60 days prior to the Redemption Date by the Trustee, from the Outstanding
Securities of such series not previously called for redemption, by such method as the Trustee shall
deem fair and appropriate and which may provide for the selection for redemption of portions (equal
to the minimum authorized denomination for Securities (including coupons, if any) of that series
with Equivalent Principal Terms or any integral multiple thereof) of the principal amount of
Securities (including coupons, if any) of such series with Equivalent Principal Terms 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 Securities selected for partial redemption, the principal amount
thereof to be redeemed. If the Securities (including coupons, if any) of a series having different
issue dates, interest rates and maturities (whether or not originally issued in a Periodic
Offering) are to be redeemed, the Company in its discretion may select the particular Securities or
portions thereof to be redeemed and shall notify the Trustee thereof by such time prior to the
relevant redemption date or dates as the Company and the Trustee may agree.

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

     Section 10.4. NOTICE OF REDEMPTION. Unless otherwise specified as contemplated by Section
3.1, notice of redemption shall be given by first-class mail, postage prepaid, mailed not less than
30 days nor more than 60 days prior to the Redemption Date, unless a shorter period is specified in
the Securities to be redeemed, to each Holder of the Securities to be redeemed.

     All notices of redemption shall state:

     (1) the Redemption Date;

     (2) the Redemption Price and the amount of accrued interest, if any, to be paid;

63

 

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

     (4) in case any Security is to be redeemed in part only, the notice which relates to such
Security shall state that on and after the Redemption Date, upon surrender of such Security, the
Holder of such Security will receive, without a charge, a new Security or Securities of authorized
denominations for the principal amount thereof remaining unredeemed;

     (5) the Place or Places of Payment where such Securities are to be surrendered for payment for
the Redemption Price;

     (6) that Securities of the series called for redemption and all unmatured coupons, if any,
appertaining thereto must be surrendered to the Paying Agent to collect the Redemption Price;

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

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

     (9) that, unless otherwise specified in such notice, Bearer Securities of any series, if any,
surrendered for redemption must be accompanied by all coupons maturing subsequent to the Redemption
Date or the amount of any such missing coupon or coupons will be deducted from the Redemption
Price, unless security or indemnity satisfactory to the Company, the Trustee and any Paying Agent
is furnished;

     (10) if Bearer Securities of any series are to be redeemed and any Registered Securities of
such series are not to be redeemed and if such Bearer Securities may be exchanged for Registered
Securities not subject to redemption on this Redemption Date pursuant to Section 3.5 or otherwise,
the last date, as determined by the Company, on which such exchanges may be made; and

     (11) the CUSIP number, if any, of such Securities.

     Notice of redemption of Securities to be redeemed at the election of the Company shall be
given by the Company or, at the Company’s request, by the Trustee in the name and at the expense of
the Company (provided that the Company prepare and provide to the Trustee the form of such notice,
or, if acceptable to the Trustee, provides sufficient information to enable the Trustee to prepare
such notice, in each case on a timely basis.)

     Section 10.5. 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 9.3) an amount of money in the
currency or currencies (including currency units or composite currencies) in which the Securities
of such series are payable (except as otherwise specified pursuant to Section 3.1 for the
Securities of such series) sufficient to pay on the Redemption Date the Redemption

64

 

Price of, and (unless the Redemption Date shall be an Interest Payment Date) interest accrued
to the Redemption Date on, all Securities or portions thereof which are to be redeemed on that
date.

     Unless any Security by its terms prohibits any sinking fund payment obligation from being
satisfied by delivering and crediting Securities (including Securities redeemed otherwise than
through a sinking fund), the Company may deliver such Securities to the Trustee for crediting
against such payment obligation in accordance with the terms of such Securities and this Indenture.

     Section 10.6. SECURITIES PAYABLE ON REDEMPTION DATE. Notice of redemption having been given
as aforesaid, the Securities so to be redeemed shall, on the Redemption Date, become due and
payable at the Redemption Price therein specified, and from and after such date (unless the Company
shall default in the payment of the Redemption Price and accrued interest) such Securities shall
cease to bear interest and the coupons for any such interest appertaining to any Bearer Security so
to be redeemed, except to the extent provided below, shall be void and such Securities shall cease
from and after the Redemption Date to be entitled to any benefit or security under this Indenture,
and the Holders thereof shall have no right in respect of such Securities except the right to
receive the Redemption Price thereof and unpaid interest to the Redemption Date. Except as
provided in the next succeeding paragraph, upon surrender of any such Security, including coupons,
if any, for redemption in accordance with said notice, such Security shall be paid by the Company
at the Redemption Price, together with accrued interest, if any, to the Redemption Date; provided,
however, that unless otherwise specified as contemplated by Section 3.1, installments of interest
on Bearer Securities whose Stated Maturity is on or prior to the Redemption Date and the principal
of, and premium, if any, on such Bearer Securities shall be payable only at an office or agency
located outside the United States and it possessions (except as otherwise provided in Section 9.2)
and, unless otherwise specified as contemplated by Section 3.1, only upon presentation and
surrender of coupons for such interest; and provided, further, that, unless otherwise specified as
contemplated by Section 3.1, installments of interest on Registered Securities whose Stated
Maturity is on or prior to the Redemption Date shall be payable to the Holders of such Securities,
or one or more Predecessor Securities, registered as such at the close of business on the relevant
Record Dates according to their terms and the provisions of Section 3.7.

     If any Bearer Security surrendered for redemption shall not be accompanied by all appurtenant
coupons maturing after the Redemption Date, such Bearer Security may be paid after deducting from
the Redemption Price an amount equal to the face amount of all such missing coupons, or the
surrender of such missing coupon or coupons may be waived by the Company and the Trustee if there
be furnished to them such security or indemnity as they may require to save each of them and any
Paying Agent harmless. If thereafter the Holder of such Bearer Security shall surrender to the
Trustee or any Paying Agent any such missing coupon in respect of which a deduction shall have been
made from the Redemption Price, such Holder shall be entitled to receive the amount so deducted;
provided, however, that interest represented by coupons shall be payable only at an office or
agency located outside of the United States (except as otherwise provided pursuant to Section 9.2)
and, unless otherwise specified as contemplated by Section 3.1, only upon presentation and
surrender of those coupons.

65

 

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

     Section 10.7. SECURITIES REDEEMED IN PART. Upon surrender of a Security that is redeemed only
in part at any Place of Payment therefor (with, if the Company or the Trustee so require, 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), the
Company shall execute and the Trustee shall authenticate and deliver to the Holder of that
Security, without service charge, a new Security or Securities of the same series, having the same
form, terms and Stated Maturity, in any authorized denomination equal in aggregate principal amount
to the unredeemed portion of the principal amount of the Security surrendered.

ARTICLE XI

SINKING FUNDS

     Section 11.1. APPLICABILITY OF ARTICLE. The provisions of this Article shall be applicable to
any sinking fund for the retirement of Securities of a series except as otherwise specified as
contemplated by Section 3.1 for Securities of such series.

     The minimum amount of any sinking fund payment provided for by the terms of Securities of any
series is herein referred to as a “mandatory sinking fund payment,” and any payment in excess of
such minimum amount provided for by the terms of Securities of any series is herein referred to as
an “optional sinking fund payment.” If provided for by the terms of Securities of any series, the
cash amount of any sinking fund payment may be subject to reduction as provided in Section 11.2.
Each sinking fund payment shall be applied to the redemption of Securities of any series as
provided for by the terms of Securities of such series.

     Section 11.2. SATISFACTION OF SINKING FUND PAYMENTS WITH SECURITIES. The Company (i) may
deliver Outstanding Securities of a series (other than any previously called for redemption)
together, in the case of Bearer Securities of such series, with all unmatured coupons appertaining
thereto and (ii) may apply as a credit Securities of a series which have been redeemed either at
the election of the Company pursuant to the terms of such Securities or through the application of
permitted optional sinking fund payments pursuant to the terms of such Securities, in each case in

AMENDMENT NO. 19 TO

AMENDED AND RESTATED CREDIT AGREEMENT

     This Amendment No. 19 to Amended and Restated Credit Agreement (this “Amendment”), dated as of
February 8, 2008, is entered into by and between SIFCO INDUSTRIES, INC. (the “Borrower”) and
NATIONAL CITY BANK (the “Bank”) for the purposes amending and supplementing the documents and
instruments referred to below.

WITNESSETH:

     WHEREAS, Borrower and Bank are parties to an Amended and Restated Credit Agreement made as of
April 30, 2002, as amended from time to time (as amended, the “Credit Agreement”; all terms used in
the Credit Agreement being used herein with the same meaning); and

     WHEREAS, Borrower and Bank desire to further amend certain provisions of the Credit Agreement
to, among other things, increase the amount of the Subject Commitment to $8,000,000, extend the
Expiration Date to July 1, 2009, amend the commitment fee, change pricing to Prime flat, and
amend/waive certain financial covenants;

     NOW, THEREFORE, in consideration of the foregoing and the mutual covenants and agreements
contained herein and for other good and valuable consideration, the receipt and sufficiency of
which is hereby acknowledged, the parties agree as follows:

SECTION I — Amendments to Credit Agreement

A. Subsection 2A.01 of the Credit Agreement is hereby amended to increase the maximum amount
of the Subject Commitment from Six Million Dollars ($6,000,000) to Eight Million Dollars
($8,000,000). Borrower will sign an Amended and Restated Note for the new amount, the form
of which is attached hereto as Exhibit A.

B. Section 2A.02 of the Credit Agreement is hereby amended to extend the Expiration Date
from October 1, 2008 to July 1, 2009.

C. Subsection 2A.04 (“COMMITMENT FEE”) of the Credit Agreement shall be amended to set the
commitment fee at thirty-five hundredths of one percent (.35%).

D. Subsection 2B.10 (“INTEREST: PRIME RATE LOANS”) of the Credit Agreement shall be
amended to set the pre-maturity rate at Prime flat.

E. Subsections 3B.01 and 3B.03 are hereby amended in their entirety to read as follows:

3B.01 TANGIBLE NET WORTH — Borrower shall not suffer or permit the Tangible Net Worth
of the Reporting Group, as of the end of any quarter, to be less than the required
minimum amount. The required minimum amount shall be $30,000,000.00. The required
minimum amount shall increase as of the last day of each fiscal year of Borrower,
commencing with fiscal year ending September 30, 2008, by an amount equal to 50% of the
consolidated Net Income of the Reporting Group for such fiscal year as measured by
Borrower’s annual audited financial statements for such fiscal year. If Net Income is
less than $0 for any fiscal year, the required minimum amount shall not be reduced as of
the end of that fiscal year.

3B.03 EBITDA — Borrower shall not, at the end of each EBITDA
Measurement Period, permit the aggregate of the Reporting Group’s Net Income
for that period, plus the Reporting Group’s interest expense for that period,
plus the Reporting Group’s federal, state, and local income tax expense, if
any, for that period, plus the Reporting Group’s depreciation and amortization
charges for that period, minus (plus) Ireland profit (loss) before taxes and
Ireland depreciation expense for that period, minus (plus) the Reporting
Group’s foreign currency translation adjustment to fall below Five Million
Dollars ($5,000,000).

Each “EBITDA Measurement Period” shall be a period of four (4) consecutive quarterly
fiscal periods of Borrower ending on the last day of the fourth such period. Borrower
shall provide Bank with its EBITDA figure on a quarterly basis within forty-five (45)
days of quarter end.

F. Borrower shall pay Bank an amendment fee of $2,000 upon execution of this Amendment.

SECTION II — Waiver

     Bank hereby waives all violations of the financial covenants set forth in section 3B of the
Credit Agreement which occurred prior to the date of this Amendment. The execution, delivery and
effectiveness of this Amendment and the specific waiver set forth herein shall not operate as a
waiver of any other right, power or remedy of Bank under the Credit Agreement or constitute a
continuing waiver of any kind.

SECTION
III — Representations and Warranties

     Borrower hereby represents and warrants to Bank, to the best of Borrower’s knowledge, that

	 	(A)	 	none of the representations and warranties made in the Credit Agreement or any Related
Writing (collectively, the “Loan Documents”) has ceased to be true and complete in any
material respect as of the date hereof; and
	 
	 	(B)	 	as of the date hereof no “Default” has occurred that is continuing under the Loan
Documents.

SECTION
IV — Acknowledgments Concerning Outstanding Loans

     Borrower acknowledges and agrees that, as of the date hereof, all of Borrower’s outstanding
loan obligations to Bank are owed without any offset, deduction, defense, claim or counterclaim of
any nature whatsoever. Borrower authorizes Bank to share all credit and financial information
relating to Borrower with each of Bank’s parent company and with any subsidiary or affiliate
company of such Bank or of such Bank’s parent company.

SECTION V — References

     On and after the effective date of this Amendment, each reference in the Credit Agreement to
“this Agreement”, “hereunder”, “hereof”, or words of like import referring to the Credit Agreement
shall mean and refer to the Credit Agreement as amended hereby. The Loan Documents, as amended by
this Amendment, are and shall continue to be in full force and effect and are hereby ratified and
confirmed in all respects. The execution, delivery and effectiveness of this Amendment shall not
operate as a waiver of any right, power or remedy of Bank under the Loan Documents or constitute a
waiver of any provision of the Loan Documents except as specifically set forth herein.

SECTION VI — Counterparts and Governing Law

     This Amendment may be executed in any number of counterparts, each counterpart to be executed
by one or more of the parties but, when taken together, all counterparts shall constitute one
agreement. This Amendment, and the respective rights and obligations of the parties hereto, shall
be construed in accordance with and governed by Ohio law.

     IN WITNESS WHEREOF, Borrower and Bank have caused this Amendment to be executed by their
authorized officers as of the date and year first above written.

AMENDED AND RESTATED NOTE

$8,000,000                Cleveland, Ohio                February 8, 2008

FOR VALUE RECEIVED, the undersigned, SIFCO INDUSTRIES, INC. (Borrower), an Ohio
corporation, promises to pay to the order of NATIONAL CITY BANK, at the payee’s main office in
Cleveland, Ohio, the principal sum of

EIGHT MILLION DOLLARS

(or, if less, the aggregate unpaid principal balance from time to time shown on the reverse side),
together with interest computed thereon in accordance with the Credit Agreement referred to below,
which principal and interest is payable in accordance with the provisions in the Credit Agreement.

This note is issued pursuant to a certain Amended and Restated Credit Agreement (the “Credit
Agreement”) made as of April 30, 2002 by and between the payee and Borrower. The Credit Agreement
contains definitions applicable to this note, provisions governing the making of loans, the
acceleration of the maturity thereof, rights of prepayment and other provisions applicable to this
note. Each endorsement, if any, on the reverse side of this note (or any allonge thereto) shall be
prima facie evidence of the data so endorsed.

This note is issued in substitution for that certain $10,000,000 Note dated April 30, 2002 (the
“Old Note”). This Note is not intended as a novation of the obligations of Borrower under the Old
Note but rather is merely a restatement of the obligations thereunder after giving effect to the
Credit Agreement.

Borrower hereby authorizes any attorney at law at any time or times to appear in any state or
federal court of record in the United States of America after the indebtedness represented by this
note shall have become due, whether by lapse of time or by acceleration of maturity, to waive the
issuance and service of process, to present this note (together with any endorsement or
endorsements thereon) to the court, to admit the maturity thereof and the nonpayment thereof when
due, to confess judgment against Borrower in favor of the holder of this note for the full amount
then appearing due, together with interest and costs of suit, and thereupon to release all errors
and waive all rights of appeal and stay of execution. The foregoing warrant of attorney shall
survive any judgment, it being understood that should any judgment against Borrower be vacated for
any reason, the holder of this note may nevertheless utilize the foregoing warrant of attorney in
thereafter obtaining additional judgment or judgments against Borrower.

WARNING BY SIGNING THIS PAPER YOU GIVE UP YOUR RIGHT TO NOTICE AND COURT TRIAL. IF YOU DO NOT PAY
ON TIME A COURT JUDGMENT MAY BE TAKEN AGAINST YOU WITHOUT YOUR PRIOR KNOWLEDGE AND THE POWERS OF A
COURT CAN BE USED TO COLLECT FROM YOU REGARDLESS OF ANY CLAIMS YOU MAY HAVE AGAINST THE CREDITOR
WHETHER FOR RETURNED GOODS, FAULTY GOODS, FAILURE ON HIS PART TO COMPLY WITH THE AGREEMENT, OR ANY
