THE SECURITIES

     SECTION 2.01. FORM AND DATING.

          (a) GENERAL. The Securities of each series shall be in substantially the form attached hereto
as Exhibit A-1, or such other form as shall be established by or pursuant to a Board Resolution or
in one or more indentures supplemental hereto, in each case with such appropriate insertions,
omissions, substitutions and other variations as are required or permitted by this Indenture, and
may have such letters, numbers or other marks of identification and such legends or endorsements
placed thereon as may be required to comply with the rules of any applicable securities exchange,
organizational document, governing instrument or law or as may, consistently herewith, be
determined by the officers executing such Securities as evidenced by their execution of the
Securities. If temporary Securities of any series are issued as permitted by Section 2.12, the
form thereof also shall be established as provided in the preceding sentence. If the forms of
Securities of any series are established by, or by action taken pursuant to, a Board Resolution, a
copy of the Board Resolution, certified by the Secretary or an Assistant Secretary of the Company
to have been duly adopted by the Board of Directors and to be in full force and effect on the date
of the certificate, together with an appropriate record of any such action taken pursuant thereto,
including a copy of the approved form of Securities shall be delivered to the Trustee at or prior
to the delivery of the Authentication Order contemplated by Section 2.04 for the authentication and
delivery of such Securities. The Trustee’s certificate of authentication shall be in substantially
the following form:

This is one of the Securities of the series designated therein and

	 	 	     Authorized Signatory

          (b) GLOBAL SECURITIES. 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 upon the written order of the Company signed by an Officer
to be delivered to the Trustee pursuant to Section 2.04 or 2.12. Subject to the provisions of
Section 2.04, Section 2.12, if applicable, and Section 2.08, 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 written order of the Company signed by an
Officer. Any instructions by the Company with respect to endorsement or delivery or redelivery of
a Security in global form shall be in writing.

     The provisions of the last paragraph of Section 2.04 shall apply to any Security in global
form if such Security was never issued and sold by the Company and the Company delivers to the
Trustee the Security in global form together with written instructions 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 2.04.

     Notwithstanding the provisions of this Section 2.01, unless otherwise specified as
contemplated by Section 2.02, payment of principal of, premium, if any, and interest on any
Security in permanent global form shall be made to the Holder thereof.

     SECTION 2.02. AMOUNT UNLIMITED; ISSUABLE IN SERIES.

          (a) The aggregate principal amount of Securities which may be authenticated and delivered

set forth, or determined in the manner provided, in an Officers’ Certificate or (iii) in one or
more indentures supplemental hereto:

          (1) the title of the Securities of the series (which title shall distinguish the

2.09, 2.12, 3.06 or 9.05 or any Securities that, pursuant to Section 2.04, are deemed
never to have been authenticated and delivered hereunder);

          (3) the date or dates on which the principal of and premium, if any, on the
Securities of the series is payable or the method or methods of determination thereof;

8

upon which, Securities of the series may be redeemed, in whole or in part, at the option
of the Company and, if other than as provided in Section 3.02, the manner in which the
particular Securities of such series (if less than all Securities of such series are to be
redeemed) are to be selected for redemption;

limitation, on a currency or currencies (including currency unit or units) other than that
in which the Securities of the series are denominated or designated to be payable), the

          (16) under what circumstances, if any, and with what procedures and documentation the
Company will pay additional amounts on the Securities of that series held by a Person who

specified in this Indenture, the form and terms of such certificates, documents or
conditions;

          (23) the terms and conditions of any right to convert or exchange Securities of the
series into or for other securities or property of the Company;

          (24) whether the Securities are secured or unsecured, and if secured, the security
and related terms in connection therewith (which shall be provided for in a separate
security agreement and/or other appropriate documentation), each in form satisfactory to
the Trustee; and

          (25) any other terms of the series (which terms shall not be inconsistent with the
provisions of this Indenture) including any terms which may be required by or advisable
under United States laws or regulations or advisable (as determined by the Company) in
connection with the marketing of Securities of the series.

          (c) All Securities of any one series shall be substantially identical except as to
denomination and except as may otherwise be provided (i) by a Board Resolution, (ii) by action
taken pursuant to a Board Resolution and 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. The Company may, subject to obtaining all necessary corporate approvals but without the
consent of any Holder of a Security, issue additional Securities in a series having the same CUSIP
number and the same ranking, interest rate, maturity and other terms as the other Securities of the
series. The Securities of each series shall be issuable only in fully registered form without
coupons.

          (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 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 an appropriate record of any action
taken pursuant thereto in connection with the issuance of any Securities of such series shall be
delivered to the Trustee prior to the authentication and delivery thereof.

     SECTION 2.03. DENOMINATIONS.

     Unless otherwise provided as contemplated by Section 2.02, Securities of a series denominated
in Dollars shall be issuable in denominations of U.S. $1,000 and any integral multiple thereof.
Securities denominated in a foreign currency shall be issuable in such denominations as are
established with respect to such Securities in or pursuant to this Indenture.

11

 

     SECTION 2.04. EXECUTION AND AUTHENTICATION.

     An Officer shall sign the Securities for the Company by manual or facsimile signature.

     If an Officer whose signature is on a Security no longer holds that office at the time a
Security is authenticated, the Security shall nevertheless be valid.

     A Security shall not be valid until authenticated by the manual signature of an authorized
officer of the Trustee. The signature shall be conclusive evidence that the Security has been
authenticated under this Indenture.

     The Trustee shall, upon a written order of the Company signed by an Officer (an
“AUTHENTICATION ORDER”), together with an Officers’ Certificate and an Opinion of Counsel,
authenticate Securities for original issue in the aggregate principal amount and pursuant to such
procedures acceptable to the Trustee as are stated in the Authentication Order. In addition to the
matters required by Section 12.05, such Officers’ Certificate and Opinion of Counsel shall cover
such other matters as the Trustee shall reasonably request.

     The Trustee may appoint an authenticating agent acceptable to the Company to authenticate
Securities. An authenticating agent may authenticate Securities whenever the Trustee may do so.
Each reference in this Indenture to authentication by the Trustee includes authentication by such
agent. An authenticating agent has the same rights as an Agent to deal with Holders or an
Affiliate of the Company.

     Notwithstanding the foregoing, if any Security shall have been authenticated and delivered
hereunder but never issued and sold by the Company, and the Company shall deliver such Security to
the Trustee for cancellation as provided in Section 2.13 together with a written statement 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 2.05. REGISTRAR AND PAYING AGENT; APPOINTMENT OF DEPOSITARY.

     The Company shall maintain an office or agency where Securities may be presented for
registration of transfer or for exchange (“REGISTRAR”) and an office or agency where Securities may
be presented for payment (“PAYING AGENT”). The Registrar shall keep a register of the Securities
and of their transfer and exchange. The Company may appoint one or more co-registrars and one or
more additional paying agents. The term “REGISTRAR” includes any co-registrar and the term “PAYING
AGENT” includes any additional paying agent. Notwithstanding anything herein to the contrary,
there shall be only one register for the Securities. The Company may change any Paying Agent or
Registrar without notice to any Holder. The Company shall promptly notify the Trustee in writing
of the name and address of any Agent not a party to this Indenture. If the Company fails to
appoint or maintain another entity as Registrar or Paying Agent, the Trustee shall act as such.
The Company or any of its Subsidiaries may act as Paying Agent or Registrar.

     The Company initially appoints The Depository Trust Company to act as Depositary with respect
to the Global Securities.

12

 

     The Company initially appoints the Trustee to act as the Registrar and Paying Agent with
respect to the Securities and to act as Custodian with respect to the Global Securities.

     SECTION 2.06. PAYING AGENT TO HOLD MONEY IN TRUST.

     The Company shall require each Paying Agent other than the Trustee to agree in writing that
the Paying Agent will hold in trust for the benefit of Holders or the Trustee all money held by the
Paying Agent for the payment of principal, premium or interest on the Securities or other payments
in respect of the Securities or otherwise held by it as Paying Agent, and will notify the Trustee
of any default by the Company in making any such payment when due. While any such default
continues, the Trustee may require a Paying Agent to pay all money held by it to the Trustee. The
Company at any time may require a Paying Agent to pay all money held by it to the Trustee. Upon
payment over to the Trustee, the Paying Agent (if other than the Company or a Subsidiary) shall
have no further liability for the money. If the Company or a Subsidiary acts as Paying Agent, it
shall segregate and hold in a separate trust fund for the benefit of the Holders all money held by
it as Paying Agent. Upon any bankruptcy or reorganization proceedings relating to the Company, the
Trustee shall serve as Paying Agent for the Securities.

     SECTION 2.07. 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 all Holders and shall otherwise comply with TIA
§ 312(a). If the Trustee is not the Registrar, the Company shall furnish to the Trustee at least
seven Business Days before each Interest Payment Date 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
of the names and addresses of the Holders of Securities, and the Company shall otherwise comply
with TIA § 312(a).

     SECTION 2.08. TRANSFER AND EXCHANGE.

          (a) Upon surrender for registration of transfer of any Security of any series at the office or
agency maintained pursuant to Section 4.02 in a place of payment for that series, the Company shall
execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee
or transferees, one or more new Securities of the same series, of any authorized denominations and
of a same aggregate principal amount and like tenor and containing identical terms and provisions.

          (b) At the option of the Holder, Securities of any series (except a Security in global form)
may be exchanged for other Securities of the same series, of any authorized denominations, of a
same aggregate principal amount and like tenor and containing identical terms and provisions, upon
surrender of the Securities to be exchanged at such office or agency. Whenever any Securities are
so surrendered for exchange, the Company shall execute, and the Trustee shall authenticate and
deliver, the Securities which the Holder making the exchange is entitled to receive.

          (c) Notwithstanding any other provision of this Section, unless and until it is exchanged in
whole or in part for Securities in certificated form, a Security in global form representing all or
a portion of the Securities of a series may not be transferred except as a whole

13

 

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

          (d) If at any time the Depositary for the Securities of a series notifies the Company that it
is unwilling or unable to continue as Depositary for the Securities of such series or if at any
time the Depositary for the Securities of such series shall no longer be registered and in good
standing as a clearing agency under the Exchange Act, the Company shall appoint a successor
Depositary with respect to the Securities of such series. If a successor Depositary for the
Securities of such series is not appointed by the Company prior to the resignation of the
Depositary and, in any event, within 90 days after the Company receives such notice or becomes
aware of such ineligibility, the Company’s designation of the Depositary pursuant to Section
2.02(b)(20) shall no longer be effective with respect to the Securities of such series, and the
Company shall execute, and the Trustee, upon receipt of an Authentication 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. Upon the occurrence of an Event of Default, any Securities in
book-entry form only at the Depositary will be exchanged in a like manner for certificated
Securities registered in the name of the beneficial owner of such Securities or its nominee.

          (e) The Company may at any time in its sole discretion, and subject to the procedures of the
Depositary, determine that all (but not less than all) 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 an Authentication 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.

          (f) If specified by the Company pursuant to Section 2.02 with respect to a series of
Securities, the Depositary for such series may surrender a Security in global form of such series
in exchange in whole or in part for Securities of such series in certificated form on such terms as
are acceptable to the Company and such Depositary. Thereupon, the Company shall execute, and the
Trustee shall authenticate and deliver, without service charge,

     (i) to each Person specified by such Depositary 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 Depositary a new Security in global form of like tenor in a
denomination equal to the difference, if any, between the principal amount of the

14

 

surrendered Security in global form and the aggregate principal amount of
certificated Securities delivered to Holders thereof.

          (g) Upon the exchange of a Security in global form for Securities in certificated form, such
Security in global form shall be canceled by the Trustee. 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 Depositary for such Security in global form,
pursuant to instructions from its direct or Indirect Participants or otherwise, shall instruct the
Trustee in writing. The Trustee shall deliver such Securities to the Persons in whose names such
Securities are so registered.

          (h) 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.

          (i) 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.

          (j) Every 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.

          (k) 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 2.12, 9.05 or 3.06 not involving any
transfer.

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

          (m) The foregoing provisions relating to registration, transfer and exchange may be modified,
supplemented or superseded with respect to any series of Securities by a Board Resolution or in one
or more indentures supplemental hereto.

          (n) The following legend shall appear on the face of all Global Securities unless specifically
stated otherwise in the applicable provision of this Indenture:

“Unless this certificate is presented by an authorized
representative of The Depository Trust Company, a New York
corporation

15

 

(“DTC”), to Issuer or its agent for registration of transfer,
exchange, or payment, and any certificate issued is registered in
the name of Cede & Co. or in such other name as is requested by an
authorized representative of DTC (and any payment is made to Cede &
Co. or to such other entity as is requested by an authorized
representative of DTC), ANY TRANSFER, PLEDGE, OR OTHER USE HEREOF
FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL inasmuch as
the registered owner hereof, Cede & Co., has an interest herein.”

          (o) At such time as all beneficial interests in a particular Global Security have been
exchanged for definitive Securities or a particular Global Security has been redeemed, repurchased
or canceled in whole and not in part, each such Global Security shall be returned to or retained
and canceled by the Trustee in accordance with Section 2.13 hereof. At any time prior to such
cancellation, if any beneficial interest in a Global Security is exchanged for or transferred to a
Person who will take delivery thereof in the form of a beneficial interest in another Global
Security or for definitive Securities, the principal amount of Securities represented by such
Global Security shall be reduced accordingly and an endorsement shall be made on such Global
Security by the Trustee or by the Depositary at the direction of the Trustee to reflect such
reduction; and if the beneficial interest is being exchanged for or transferred to a Person who
will take delivery thereof in the form of a beneficial interest in another Global Security, such
other Global Security shall be increased accordingly and an endorsement shall be made on such
Global Security by the Trustee or by the Depositary at the direction of the Trustee to reflect such
increase.

          (p) Prior to due presentment for the registration of a transfer of any Security, the Trustee,
any Agent and the Company may deem and treat the Person in whose name any Security is registered as
the absolute owner of such Security for the purpose of receiving payment of principal of and
(subject to the record date provisions of such Security) interest on such Securities and for all
other purposes, and neither the Trustee, any Agent nor the Company shall be affected by notice to
the contrary. Notwithstanding the foregoing, with respect to any Global Security, nothing herein
shall prevent the Company, the Trustee or any agent of the Company or the Trustee from giving
effect to any written certification, proxy or other authorization furnished by any Depositary, as a
Holder, with respect to such Global Security or impair, as between such Depositary and owners of
beneficial interests in such Global Security, the operation of customary practices governing the
exercise of the rights of such Depositary (or its nominee) as Holder of such Global Security.

          (q) None of the Company, the Trustee nor any agent of the Company or the Trustee will have any
responsibility or liability for any aspect of the records relating to or payments made on account
of beneficial ownership interests of a Global Security or maintaining, supervising or reviewing any
records relating to such beneficial ownership interests.

     SECTION 2.09. REPLACEMENT SECURITIES.

     If any mutilated Security is surrendered to the Trustee or the Company and the Trustee
receives evidence to its satisfaction of the destruction, loss or theft of any Security, the
Company

16

 

shall issue and the Trustee, upon receipt of an Authentication Order, shall authenticate a
replacement Security if the Trustee’s requirements are met. If required by the Trustee or the
Company, an indemnity bond must be supplied by the Holder that is sufficient in the judgment of the
Trustee and the Company to protect the Company, the Trustee, any Agent and any authenticating agent
from any loss that any of them may suffer if a Security is replaced. The Company may charge for
its expenses in replacing a Security.

     Every replacement Security is an additional obligation of the Company and shall be entitled to
all of the benefits of this Indenture equally and proportionately with all other Securities duly
issued hereunder.

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

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

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

     SECTION 2.10. OUTSTANDING SECURITIES.

     The Securities outstanding at any time are all the Securities authenticated by the Trustee
except for those canceled by it, those delivered to it for cancellation, those reductions in the
interest in a Global Security effected by the Trustee in accordance with the provisions hereof, and
those described in this Section as not outstanding. Except as set forth in Section 2.11 hereof, a
Security does not cease to be outstanding because the Company or an Affiliate of the Company holds
the Security.

     If a Security is replaced pursuant to Section 2.09 hereof, it ceases to be outstanding unless
the Trustee receives proof satisfactory to it that the replaced Security is held by a “protected
purchaser” (within the meaning of Article 8 of the Uniform Commercial Code) or a Person with
comparable status under other applicable law.

     If the principal amount of any Security is considered paid under Section 4.01 hereof, it
ceases to be outstanding and interest on it ceases to accrue.

     If the Paying Agent (other than the Company, a Subsidiary or an Affiliate of any thereof)
holds, on a redemption date or maturity date, money sufficient to pay Securities payable on that
date, then on and after that date such Securities shall be deemed to be no longer outstanding and
shall cease to accrue interest.

17

 

     SECTION 2.11. TREASURY SECURITIES.

     In determining whether the Holders of the required principal amount of Securities have
concurred in any direction, waiver or consent, Securities owned by the Company, or by any Person
directly or indirectly controlling or controlled by or under direct or indirect common control with
the Company, shall be considered as though not outstanding, except that for the purposes of
determining whether the Trustee shall be protected in relying on any such direction, waiver or
consent, only Securities that a Responsible Officer of the Trustee actually knows are so owned
shall be so disregarded.

     SECTION 2.12. TEMPORARY SECURITIES.

     Until certificates representing Securities are ready for delivery, the Company may prepare and
the Trustee, upon receipt of an Authentication Order, shall authenticate temporary Securities.
Temporary Securities shall be substantially in the form of certificated Securities but may have
variations that the Company considers appropriate for temporary Securities and as shall be
reasonably acceptable to the Trustee. Without unreasonable delay, the Company shall prepare and
the Trustee shall authenticate definitive Securities in exchange for temporary Securities.

     Holders of temporary Securities shall be entitled to all of the benefits of this Indenture.

     SECTION 2.13. CANCELLATION.

     The Company at any time may deliver Securities to the Trustee for cancellation. The Registrar
and Paying Agent shall forward to the Trustee any Securities surrendered to them for registration
of transfer, exchange or payment. The Trustee and no one else shall cancel all Securities
surrendered for registration of transfer, exchange, payment, replacement or cancellation and shall
dispose of canceled Securities in accordance with its customary procedures (subject to the record
retention requirement of the Exchange Act). Certification of the disposition of all canceled
Securities shall be delivered to the Company. The Company may not issue new Securities to replace
Securities that it has paid or that have been delivered to the Trustee for cancellation.

     SECTION 2.14. DEFAULTED INTEREST.

     If the Company defaults in a payment of interest on the Securities, it shall pay the defaulted
interest in any lawful manner plus, to the extent lawful, interest payable on the defaulted
interest, to the Persons who are Holders on a subsequent special record date, in each case at the
rate provided in the Securities. The Company shall notify the Trustee in writing of the amount of
defaulted interest proposed to be paid on each Security and the date of the proposed payment. The
Company shall fix or cause to be fixed each such special record date and payment date; PROVIDED
that no such special record date shall be less than 10 days prior to the related payment date for
such defaulted interest. At least 15 days before the special record date, the Company (or, upon
the written request of the Company, the Trustee in the name and at the expense of the Company)
shall mail or cause to be mailed to Holders a notice that states the special record date, the
related payment date and the amount of such interest to be paid. Subject to the foregoing
provisions of this Section, each Security delivered under this Indenture upon

18

 

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.

ARTICLE 3

REDEMPTION AND PREPAYMENT

     SECTION 3.01. APPLICABILITY OF ARTICLE.

     The provisions of this Article shall be applicable to the Securities of any series which are
redeemable before their maturity or to any sinking fund for the retirement of Securities of a
series except as otherwise specified as contemplated by Section 2.02 for Securities of such series.

     SECTION 3.02. SELECTION OF SECURITIES TO BE REDEEMED.

     If less than all of the Securities of any series are to be redeemed at any time, the Trustee
shall select the Securities of such series to be redeemed among the Holders of the Securities of
such series by such method as the Trustee deems fair and appropriate; PROVIDED that no Securities
of $1,000 or less shall be redeemed in part. The particular Securities of such series to be
redeemed shall be selected, unless otherwise provided herein, not less than 30 nor more than 60
days prior to the redemption date by the Trustee from the outstanding Securities of the series not
previously called for redemption.

     The Trustee shall promptly notify the Company in writing of the Securities selected for
redemption and, in the case of any Security selected for partial redemption, the principal amount
thereof to be redeemed. Securities and portions of Securities selected shall be in amounts of
$1,000 or whole multiples of $1,000; except that if all of the Securities of a series of a Holder
are to be redeemed, the entire outstanding amount of Securities of such series held by such Holder,
even if not a multiple of $1,000, shall be redeemed. A new Security of the same series and tenor
in principal amount equal to the unredeemed portion thereof will be issued in the name of the
Holder thereof upon cancellation of the original Security. Securities called for redemption shall
become due on the redemption date. On and after the redemption date, interest will cease to accrue
on the Securities or portions of them called for redemption. Except as provided in this Section
3.02, provisions of this Indenture that apply to Securities called for redemption shall also apply
to portions of Securities called for redemption.

     SECTION 3.03. NOTICE OF REDEMPTION.

     The election of the Company to redeem any Securities shall be evidenced by a Board Resolution
or in another manner specified as contemplated by Section 2.02 for such Securities. In case of any
redemption at the election of the Company, the Company shall, at least 45 days prior to the
redemption date fixed by the Company (unless a shorter notice shall be satisfactory to the
Trustee), notify the Trustee of such redemption date, of the principal amount of Securities of such
series to be redeemed and, if applicable, of the tenor of the Securities to be redeemed. In the
case of any redemption of Securities (a) prior to the expiration of any restriction on such
redemption provided in the terms of such Securities or elsewhere in this Indenture, or (b) pursuant
to an election of the Company which is subject to a condition specified in the terms of such
Securities or elsewhere in this Indenture, the Company shall furnish the Trustee with an Officers’
Certificate evidencing compliance with such restriction or condition.

19

 

     At least 30 days but not more than 60 days before a redemption date, the Company shall mail or
cause to be mailed, by first class mail, a notice of redemption to each Holder whose Securities are
to be redeemed at its registered address.

     The notice shall identify the Securities to be redeemed, including the series thereof, and
shall state:

               (a) the redemption date;

               (b) the redemption price;

               (c) the name and address of the Paying Agent;

               (d) that Securities called for redemption must be surrendered to the Paying Agent to collect
the redemption price;

               (e) that, unless the Company defaults in making such redemption payment, interest on
Securities called for redemption will cease to accrue on and after the redemption date;

               (f) that in the case of any Security being redeemed in part, the portion of the principal
amount of such Security to be redeemed and that, after the redemption date upon surrender of such
Security, a new Security or Securities of the same series and tenor in principal amount equal to
the unredeemed portion shall be issued upon cancellation of the original;

               (g) the paragraph of the Securities and/or Section of this Indenture pursuant to which the
Securities called for redemption are being redeemed; and

               (h) that no representation is made as to the correctness or accuracy of the CUSIP number, if
any, listed in such notice or printed on the Securities.

     At the Company’s request, the Trustee shall give the notice of redemption in the Company’s
name and at the Company’s expense; PROVIDED, HOWEVER, that the Company shall have delivered to the
Trustee, at least 45 days prior to the redemption date, an Officers’ Certificate requesting that
the Trustee give such notice and setting forth the information to be stated in such notice as
provided in the preceding paragraph.

     SECTION 3.04. EFFECT OF NOTICE OF REDEMPTION.

     Once notice of redemption is mailed in accordance with Section 3.03 hereof, Securities called for
redemption become irrevocably due and payable on the redemption date at the redemption price. A
notice of redemption may not be conditional.

     SECTION 3.05. DEPOSIT OF REDEMPTION OR PURCHASE PRICE.

     One Business Day prior to 10:00 a.m., Eastern Time, on any redemption date or purchase date,
the Company shall deposit with the Trustee or with the Paying Agent money in immediately available
funds sufficient to pay the redemption or purchase price of and accrued interest, if any, on all
Securities to be redeemed or purchased on that date. The Trustee or the

20

 

Paying Agent shall promptly return to the Company any money deposited with the Trustee or the
Paying Agent by the Company in excess of the amounts necessary to pay the redemption or purchase
price of, and accrued interest on, all Securities to be redeemed or purchased.

     SECTION 3.06. SECURITIES REDEEMED OR PURCHASED IN PART.

     Upon surrender of a Security that is redeemed or purchased in part, the Company shall issue
and, upon the Company’s written request, the Trustee shall authenticate for the Holder at the
expense of the Company a new Security of the same series and tenor equal in principal amount to the
unredeemed or unpurchased portion of the Security surrendered.

     SECTION 3.07. MANDATORY REDEMPTION; SINKING FUND.

     The Company shall not be required to make mandatory redemption or sinking fund payments with
respect to the Securities, unless otherwise specified in the terms of a particular series of
Securities. If a mandatory or optional sinking fund is specified in the terms of a particular
series of Securities, the following provisions will apply thereto (unless otherwise specified):

     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.” The last date on which any such payment may be made is herein
referred to as a “sinking fund payment date.”

     In lieu of making all or any part of any mandatory sinking fund payment with respect to any
Securities of a series in cash, the Company may at its option (a) deliver to the Trustee Securities
of that series theretofore purchased by the Company and (b) may apply as a credit Securities of
that series which have been redeemed either at the election of the Company pursuant to the terms of
such Securities or through the application of optional sinking fund payments pursuant to the next
succeeding paragraph, in each case in satisfaction of all or any part of any mandatory sinking fund
payment, PROVIDED that such Securities have not been previously so credited. Each such Security so
delivered or applied as a credit shall be credited at the sinking fund redemption price for such
Securities and the amount of any mandatory sinking fund shall be reduced accordingly. If the
Company intends so to deliver or credit such Securities with respect to any mandatory sinking fund
payment it shall deliver to the Trustee at least 45 days prior to the next succeeding sinking fund
payment date for such series (a) an Officers’ Certificate specifying the portion of such sinking
fund payment, if any, to be satisfied by payment of cash and the portion of such sinking fund
payment, if any, which is to be satisfied by delivering and crediting such Securities, and stating
the basis of such credit and that such Securities have not previously been so credited, and (b) any
Securities to be so delivered. All Securities so delivered to the Trustee shall be cancelled by
the Trustee and no Securities shall be authenticated in lieu thereof. If the Company fails to
deliver such certificate and Securities at or before the time provided above, the Company shall not
be permitted to satisfy any portion of such mandatory sinking fund payment by delivery or credit of
Securities.

21

 

     At its option the Company may pay into the sinking fund for the retirement of Securities of
any particular series, on or before each sinking fund payment date for such series, any additional
sum in cash as specified by the terms of such series of Securities. If the Company intends to
exercise its right to make any such optional sinking fund payment, it shall deliver to the Trustee
at least 45 days prior to the next succeeding sinking fund payment date for such series of
Securities an Officers’ Certificate stating that the Company intends to exercise such optional
right and specifying the amount which the Company intends to pay on such sinking fund payment date.
If the Company fails to deliver such certificate at or before the time provided above, the Company
shall not be permitted to make any optional sinking fund payment with respect to such sinking fund
payment date. To the extent that such right is not exercised in any year it shall not be
cumulative or carried forward to any subsequent year.

     If the sinking fund payment or payments (mandatory or optional) made in cash plus any unused
balance of any preceding sinking fund payments made in cash shall exceed $50,000 (or a lesser sum
if the Company shall so request) with respect to the Securities of any particular series, it shall
be applied by the Trustee or one or more Paying Agents on the next succeeding sinking fund payment
date to the redemption of Securities of such series at the sinking fund redemption price together
with accrued interest to the date fixed for redemption. The Trustee shall select, in the manner
provided in Section 3.02, for redemption on such sinking fund payment date a sufficient principal
amount of Securities of such series to exhaust said cash, as nearly as may be, and the Trustee
shall, at the expense and in the name of the Company, thereupon cause notice of redemption of
Securities of such series to be given in substantially the manner and with the effect provided in
Sections 3.02 and 3.03 for the redemption of Securities of that series in part at the option of the
Company, except that the notice of redemption shall also state that the Securities of such series
are being redeemed for the sinking fund. Any sinking fund moneys not so applied or allocated by
the Trustee or any Paying Agent to the redemption of Securities of that series shall be added to
the next cash sinking fund payment received by the Trustee or the Paying Agent and, together with
such payment, shall be applied in accordance with the provisions of this Section 3.07. Any and all
sinking fund moneys held by the Trustee or any Paying Agent on the maturity date of the Securities
of any particular series, and not held for the payment or redemption of particular Securities of
such series, shall be applied by the Trustee or such Paying Agent, together with other moneys, if
necessary, to be deposited sufficient for the purpose, to the payment of the principal of the
Securities of that series at maturity. On or before each sinking fund payment date, the Company
shall pay to the Trustee or to one or more Paying Agents in cash a sum equal to all interest
accrued to the date fixed for redemption on Securities to be redeemed on the next following sinking
fund payment date pursuant to this Section. Neither the Trustee nor any Paying Agent shall redeem
any Securities of a series with sinking fund moneys, and the Trustee shall not mail any notice of
redemption of Securities for such series by operation of the sinking fund, during the continuance
of a default in payment of interest on such Securities or of any Event of Default (other than an
Event of Default occurring as a consequence of this paragraph), except that if the notice of
redemption of any Securities shall theretofore have been mailed in accordance with the provisions
hereof, the Trustee or any paying agent shall redeem such Securities if cash sufficient for that
purpose shall be deposited with the Trustee or such paying agent for that purpose in accordance
with the terms of this Article 3. Except as aforesaid, any moneys in the sinking fund for such
series at the time when any such default or Event of Default shall occur and any moneys thereafter
paid into the sinking fund shall, during the continuance of such default or Event of Default, be
held as security for the payment of all such

22

 

Securities; PROVIDED, HOWEVER, that in case such Event of Default or default shall have been
cured or waived as provided herein, such moneys shall thereafter be applied on the next succeeding
sinking fund payment date on which such moneys may be applied pursuant to the provisions of this
Section 3.07.

ARTICLE 4

COVENANTS

     SECTION 4.01. PAYMENT OF SECURITIES.

     The Company shall pay or cause to be paid the principal of, premium, if any, and interest on
the Securities on the dates and in the manner provided in the Securities. Principal, premium, if
any, and interest shall be considered paid on the date due if the Paying Agent, if other than the
Company or a Subsidiary thereof, holds as of 10:00 a.m., Eastern Time, on the due date money
deposited by the Company in immediately available funds and designated for and sufficient to pay
all principal, premium, if any, and interest then due.

     SECTION 4.02. MAINTENANCE OF OFFICE OR AGENCY.

     The Company shall maintain in the State of New York or such other place of payment specified

(which may be an office of the Trustee or an affiliate of the Trustee, Registrar or co-Registrar)
where Securities may be surrendered for registration of transfer or for exchange and where notices
and demands to or upon the Company in respect of the Securities and this Indenture may be served.
The Company shall give prompt written notice to the Trustee of the location, and any change in the
location, of such office or agency. If at any time the Company shall fail to maintain any such
required office or agency or shall fail to furnish the Trustee with the address thereof, such
presentations, surrenders, notices and demands may be made or served at the Trustee’s principal
corporate trust office in the Borough of Manhattan, the City of New York, which currently is
located at 4 New York Plaza, 15th Floor, New York, New York 10004, Attention: Worldwide
Securities Services.

     The Company may also from time to time designate one or more other offices or agencies where
the Securities 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 the Place of
Payment for such purposes. The Company shall give prompt written notice to the Trustee of any such
designation or rescission and of any change in the location of any such other office or agency.

     SECTION 4.03. REPORTS.

          (a) The Company covenants and agrees to file with the Trustee, and to provide by mail to each
Holder, within 15 days after the Company is required to file the same with the SEC, copies of the
annual reports, quarterly reports and the information, documents and other reports which the
Company is required to file with the SEC pursuant to Section 13 or Section 15(d) of the Exchange
Act.

          (b) The Company covenants and agrees to file with the Trustee and the SEC, in accordance with
the rules and regulations prescribed from time to time by the SEC, such additional information,

provided for in this Indenture as may be required from time to time by such SEC rules and
regulations.

          (c) The Company covenants and agrees to furnish to the Trustee within 120 days of the end of
each fiscal year, the compliance certificate required by TIA § 314(a)(4).

          (d) Delivery of such reports, information and documents to the Trustee is for informational
purposes only and the Trustee’s receipt of such shall not constitute constructive notice of any
information contained therein or determinable from information contained therein, including the
Company’s compliance with any of its covenants hereunder (as to which the Trustee is entitled to
rely exclusively on Officers’ Certificates).

     SECTION 4.04. COMPLIANCE CERTIFICATE.

          (a) The Company shall deliver to the Trustee, within 90 days after the end of each fiscal
year, an Officers’ Certificate stating that a review of the activities of the Company and its
Subsidiaries during the preceding fiscal year has been made under the supervision of the signing
Officers with a view to determining whether the Company has kept, observed, performed and fulfilled
its obligations under this Indenture, and further stating, as to each such Officer signing such
certificate, that to the best of his or her knowledge the Company has kept, observed, performed and
fulfilled each and every covenant contained in this Indenture and is not in default in the
performance or observance of any of the terms, provisions and conditions of this Indenture (or, if
a Default, Event of Default or other instance of non-compliance with any of the terms of this
Indenture shall have occurred, describing all such Defaults, Events of Default or instances of
non-compliance of which he or she may have knowledge and what action the Company is taking or
proposes to take with respect thereto) and that to the best of his or her knowledge no event has
occurred and remains in existence by reason of which payments on account of the principal of,
premium, if any, or interest on the Securities is prohibited or if such event has occurred, a
description of the event and what action the Company is taking or proposes to take with respect
thereto.

          (b) The Company shall, so long as any of the Securities are outstanding, deliver to the
Trustee, forthwith upon any Officer of the Company becoming aware of any Default or Event of
Default, an Officers’ Certificate specifying such Default or Event of Default and what action the
Company is taking or proposes to take with respect thereto.

     SECTION 4.05. CONTINUED EXISTENCE.

     Subject to Article 5 hereof, the Company shall do or cause to be done all things necessary to
preserve and keep in full force and effect (i) its existence as a corporation or other permitted
entity, and the corporate, partnership or other existence of each of its Significant Subsidiaries,
in accordance with the respective organizational documents (as the same may be amended from time to
time) of the Company or any such Significant Subsidiary and (ii) the rights (charter and
statutory), licenses and franchises of the Company and any of its Significant Subsidiaries;

24

 

PROVIDED, HOWEVER, that the Company shall not be required to preserve any such right, license
or franchise, or the corporate, partnership or other existence of any of its Significant
Subsidiaries, if the Board of Directors shall determine that the preservation thereof is no longer
desirable in the conduct of the business of the Company and its Significant Subsidiaries, taken as
a whole, and that the loss thereof is not adverse in any material respect to the Holders of the
Securities.

     SECTION 4.06. STAY, EXTENSION AND USURY LAWS.

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

     SECTION 5.01. MERGER, CONSOLIDATION, OR SALE OF ASSETS.

     The Company may consolidate or amalgamate with, merge into, convert itself into, or sell,
assign, transfer, lease, convey or otherwise dispose of (including any such disposition that might
be deemed to occur as a result of the conversion of the Company into another form of organization)
all or substantially all of its properties or assets in one or more related transactions, to
another Person (other than an individual, a government or an agency or political subdivision of a
government), but only if (a) either (i) the Company is the surviving entity or (ii) the Person
formed by or surviving any such consolidation, amalgamation, merger or conversion (if other than
the Company) or to which such sale, assignment, transfer, lease, conveyance or other disposition
shall have been made is a Person organized or existing under the laws of the United States, any
state thereof, or the District of Columbia, the United Kingdom or Bermuda; (b) the Person formed by
or surviving any such consolidation, amalgamation, merger or conversion (if other than the Company)

shall have been made assumes all the obligations of the Company under the Securities and this
Indenture pursuant to a supplemental indenture in a form reasonably satisfactory to the Trustee;
and (c) immediately after such transaction no Default or Event of Default exists. If the Company
requests the Trustee to enter into any supplemental indenture, or to take any other action, as a
result of such consolidation, amalgamation, merger, sale, assignment, transfer, lease, conveyance
or other disposition, the Company will also furnish to the Trustee an Officers’ Certificate and an

the Company in accordance with Section 5.01 hereof, the successor Person formed by such
consolidation or amalgamation or into or with which the Company is merged or converted or to which
such sale, assignment, transfer, lease, conveyance or other disposition is made shall succeed to,

merger, conversion, sale, assignment, transfer, lease, conveyance or other disposition, the
provisions of this Indenture referring to the “Company” shall refer instead to the successor Person
and not to the Company), and may exercise every right and power of the Company under this Indenture
with the same effect as if such successor Person had been named as the Company herein; PROVIDED,
HOWEVER, that the predecessor Company shall not be relieved from the obligation to pay the
principal of, premium, if any, and interest on the Securities except in the case of a sale,
assignment, transfer, conveyance or other disposition (other than a lease) of all or substantially
all of the Company’s properties or assets that meets the requirements of Section 5.01 hereof.

     SECTION 6.01. EVENTS OF DEFAULT.

An “Event of Default,” with respect to Securities of any series shall have occurred if:

          (a) the Company defaults in the payment when due of interest on, or with respect to, any
Security of that series and such default continues for a period of 30 days;

          (b) the Company defaults in the payment when due of principal of or premium, if any, on, or a
sinking fund payment with respect to, any Security of that series when the same becomes due and
payable at maturity, upon redemption or otherwise;

          (c) the Company fails to comply with any of the provisions of Section 5.01 hereof;

          (d) the Company fails to observe or perform any other covenant, representation, warranty or
other agreement in this Indenture, with respect to any Security of that series for 60 days after
notice to comply;

          (e) the Company, pursuant to or within the meaning of any Bankruptcy Law:

     (i) commences a voluntary case;

     (ii) consents to the entry of an order for relief against it in an involuntary
case;

     (iii) consents to the appointment of a custodian of it or for all or
substantially all of its property;

     (iv) makes a general assignment for the benefit of its creditors; or

26

 

     (v) generally is not paying its debts as they become due;

          (f) a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that:

     (i) is for relief against the Company in an involuntary case;

     (ii) appoints a custodian of the Company for all or substantially all of the
property of the Company; or

     (iii) orders the liquidation of the Company;

and the order or decree remains unstayed and in effect for 60 consecutive days; or

          (g) any other event provided with respect to Securities of that series in the terms thereof as
contemplated by Section 2.02 hereof shall occur.

     The term “CUSTODIAN” as used in this Article 6 means any receiver, trustee, assignee,
liquidator or similar official under any Bankruptcy Law.

     A Default under clause (d) with respect to the Securities of any series is not an Event of
Default until the Trustee notifies the Company, or the Holders of at least 25% in principal amount
of the then outstanding Securities of all series affected by the Default (treating all such series
as a single class) notify the Company and the Trustee, of the Default and the Company does not cure
the Default within 60 days after receipt of the notice. The notice must specify the Default,
demand that it be remedied and state that the notice is a “NOTICE OF DEFAULT.”

     SECTION 6.02. ACCELERATION.

     If any Event of Default with respect to one or more series of Securities (other than an Event
of Default specified in clause (e) or (f) of Section 6.01 hereof) occurs and is continuing, the
Trustee or the Holders of at least 25% in principal amount of the then outstanding Securities of
all series with respect to which an Event of Default shall have occurred and be continuing
(treating all such series as a single class) may declare all the Securities of all such series to
be due and payable immediately by a notice in writing to the Company (and to the Trustee if given
by Holders). Upon any such declaration, the principal of, premium, if any, and accrued and unpaid
interest with respect to the Securities of all such series shall become due and payable
immediately. Notwithstanding the foregoing, if an Event of Default specified in clause (e) or (f)
of Section 6.01 hereof occurs, all outstanding Securities of all series shall be due and payable
immediately without further action or notice.

     SECTION 6.03. OTHER REMEDIES.

     If an Event of Default with respect to a series of Securities occurs and is continuing, the
Trustee may pursue any available remedy to collect the payment of principal, premium, if any, and
interest on the Securities of such series or to enforce the performance of any provision of the
Securities of such series or this Indenture with respect to such series.

27

 

     The Trustee may maintain a proceeding even if it does not possess any of the Securities or
does not produce any of them in the proceeding. A delay or omission by the Trustee or any Holder
of a Security in exercising any right or remedy accruing upon an Event of Default shall not impair
the right or remedy or constitute a waiver of or acquiescence in the Event of Default. All
remedies are cumulative to the extent permitted by law.

     SECTION 6.04. WAIVER OF PAST DEFAULTS; RESCISSION OF ACCELERATION.

     Holders of a majority in aggregate principal amount of the then outstanding Securities of all
series affected (treating all such series as a single class) may, by notice to the Trustee, on
behalf of the Holders of all of the Securities of all such series, waive an existing Default or
Event of Default with respect to such series and its consequences hereunder (including in
connection with an offer to purchase or exchange), except a continuing Default or Event of Default
in the payment of the principal of, premium, if any, interest on, or any sinking fund payment with
respect to, the Securities of such series, and except a continuing Default or Event of Default
under any provision of this Indenture that, under Section 9.02, cannot be modified or waived
without the consent of a greater number of Holders or of each Holder affected. Upon any such
waiver, such Default or Event of Default 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. The Holders of a majority in aggregate principal
amount of the then outstanding Securities of all series affected (treating all such series as a
single class) may also rescind an acceleration and its consequences with respect to all such
series, including any related payment default that resulted from such acceleration, but not
including any other payment default.

     SECTION 6.05. CONTROL BY MAJORITY.

     Holders of a majority in principal amount of the then outstanding Securities of all series
with respect to which an Event of Default shall have occurred and be continuing (treating all such
series as a single class) may direct the time, method and place of conducting any proceeding for
exercising any remedy available to the Trustee or exercising any trust or power conferred on it;
PROVIDED that:

     (i) such direction shall not be in conflict with any law or rule or with this
Indenture;

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

     (iii) the Trustee need not take any action which might involve it in personal
liability or be unduly prejudicial to the Holders of Securities of such series not
joining therein.

     SECTION 6.06. LIMITATION ON SUITS.

     A Holder of a Security of any series may pursue a remedy with respect to this Indenture or the
Securities of such series only if:

28

 

          (a) the Holder of a Security of any or all series affected gives to the Trustee written notice
of a continuing Event of Default;

          (b) the Holders of at least 25% in principal amount of the then outstanding Securities of all
affected series (treating all such series as a single class) make a written request to the Trustee
to pursue the remedy;

          (c) such Holder or Holders offer and, if requested, provide to the Trustee indemnity
satisfactory to the Trustee against any loss, liability or expense;

          (d) the Trustee does not comply with the request within 30 days after receipt of such notice,
request and offer and, if requested, provision of indemnity; and

          (e) during such 30-day period the Holders of a majority in principal amount of the then
outstanding Securities of all such series (treating all such series as a single class) do not give
the Trustee a direction inconsistent with the request.

     A Holder of a Security may not use this Indenture to prejudice the rights of another Holder of
a Security or to obtain a preference or priority over another Holder of a Security.

     SECTION 6.07. RIGHTS OF HOLDERS OF SECURITIES TO RECEIVE PAYMENT.

     Notwithstanding any other provision of this Indenture, the right of any Holder of a Security
of any series to receive payment of principal, premium, if any, and interest on such Security, on
or after the respective due dates expressed or provided for in such Security (including in
connection with an offer to purchase), 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.

     SECTION 6.08. COLLECTION SUIT BY TRUSTEE.

     If an Event of Default specified in Section 6.01(a) or (b) occurs and is continuing with
respect to any series of Securities, the Trustee is authorized to recover judgment in its own name
and as Trustee of an express trust against the Company for the whole amount of principal of,
premium, if any, and interest remaining unpaid on such Securities and interest on overdue principal
and, to the extent lawful, interest at the rate provided for in such Securities and such further
amount as shall be sufficient to cover the costs and expenses of collection, including the
reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and
counsel.

     SECTION 6.09. TRUSTEE MAY FILE PROOFS OF CLAIM.

     The Trustee is authorized to 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 (including any claim for the
reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and
counsel) and the Holders of the Securities of any series allowed in any judicial proceedings
relative to the Company (or any other obligor upon the Securities), its creditors or its property

29

 

and shall be entitled and empowered to collect, receive and distribute any money or other
property payable or deliverable on any such claims and any custodian in any such judicial
proceeding is hereby authorized by each Holder to make such payments to the Trustee, and in the
event that the Trustee shall consent to the making of such payments directly to the Holders, to pay
to the Trustee any amount due to it for the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under
Section 7.07 hereof. To the extent that the payment of any such compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the
Trustee under Section 7.07 hereof out of the estate in any such proceeding, shall be denied for any
reason, payment of the same shall be secured by a lien on, and shall be paid out of, any and all
distributions, dividends, money, securities and other properties that the Holders may be entitled
to receive in such proceeding whether in liquidation or under any plan of reorganization or
arrangement or otherwise. Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization,
arrangement, adjustment or composition affecting the Securities of any series or the rights of any
Holder, or to authorize the Trustee to vote in respect of the claim of any Holder in any such
proceeding.

     SECTION 6.10. PRIORITIES.

     If the Trustee collects any money or other property pursuant to this Article, it shall pay out
the money or other property in the following order:

     FIRST: to the Trustee, its agents and attorneys for amounts due under Section 7.07 hereof,
including payment of all compensation, expense and liabilities incurred, and all advances made, by
the Trustee and the costs and expenses of collection;

     SECOND: subject to Article 10, to Holders of Securities for amounts due and unpaid on the
Securities for principal, premium, if any, interest and any other amounts, ratably, without
preference or priority of any kind, according to the amounts due and payable on the Securities for
principal, premium, if any, interest and other amounts, respectively; and

     THIRD: subject to Article 10, to the Company or to such party as a court of competent
jurisdiction shall direct.

     The Trustee may fix a record date and payment date for any payment to Holders of Securities
pursuant to this Section 6.10.

     SECTION 6.11. UNDERTAKING FOR COSTS.

     In any suit for the enforcement of any right or remedy under this Indenture or in any suit
against the Trustee for any action taken or omitted by it as a Trustee, a court in its discretion
may require the filing by any party litigant in the suit of an undertaking to pay the costs of the
suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys’
fees, against any party litigant in the suit, having due regard to the merits and good faith of the
claims or defenses made by the party litigant. This Section does not apply to a suit by the
Trustee, a suit by a Holder of a Security pursuant to Section 6.07 hereof, or a suit by Holders of
more than 10% in principal amount of the then outstanding Securities of any series.

ARTICLE 7

TRUSTEE

     SECTION 7.01. DUTIES OF TRUSTEE.

          (a) If an Event of Default has occurred and is continuing, the Trustee shall exercise such of
the rights and powers vested in it by this Indenture or an indenture supplemental hereto, and use
the same degree of care and skill in its exercise, as a prudent person would exercise or use under
the circumstances in the conduct of its own affairs.

          (b) Except during the continuance of an Event of Default:

     (i) the duties of the Trustee shall be determined solely by the express
provisions of this Indenture or an indenture supplemental hereto, and the Trustee
need perform only those duties that are specifically set forth in this Indenture or
an indenture supplemental hereto and no others, and no implied covenants or
obligations shall be read into this Indenture or an indenture supplemental hereto
against the Trustee; and

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

          (c) The Trustee may not be relieved from liabilities for its own negligent action, its own
negligent failure to act, or its own willful misconduct, except that:

     (i) this paragraph does not limit the effect of paragraph (b) of this Section;

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

     (iii) the Trustee shall not be liable with respect to any action it takes or
omits to take in good faith in accordance with a direction received by it pursuant
to Section 6.05 hereof.

          (d) Whether or not therein expressly so provided, every provision of this Indenture that in
any way relates to the Trustee is subject to paragraphs (a), (b), and (c) of this Section.

          (e) No provision of this Indenture shall require the Trustee to expend or risk its own funds
or incur any liability.

31

 

          (f) The Trustee shall not be liable for interest on any money received by it except as the
Trustee may agree in writing with the Company. Money held in trust by the Trustee need not be
segregated from other funds except to the extent required by law.

     SECTION 7.02. RIGHTS OF TRUSTEE.

          (a) The Trustee may conclusively rely upon any document believed by it to be genuine and to
have been signed or presented by the proper Person. The Trustee need not investigate any fact or
matter stated in the document.

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

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

          (d) The Trustee shall not be liable for any action it takes or omits to take in good faith
that it believes to be authorized or within the rights or powers conferred upon it by this
Indenture.

          (e) Unless otherwise specifically provided in this Indenture, any demand, request, direction
or notice from the Company shall be sufficient if signed by an Officer of the Company.

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

          (g) The Trustee shall not be charged with knowledge or deemed to have notice of any Default or
Event of Default unless a Responsible Officer of the Trustee shall have actual knowledge thereof or
unless the Trustee shall have received notice thereof in accordance with Section 12.02.

          (h) 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 at the sole cost of the Company and

32

 

shall incur no liability or additional liability of any kind by reason of such inquiry or
investigation.

          (i) In no event shall the Trustee be responsible or liable for special, indirect, or
consequential loss or damage of any kind whatsoever (including, but not limited to, loss of profit)
irrespective of whether the Trustee has been advised of the likelihood of such loss or damage and
regardless of the form of action.

          (j) The rights, privileges, protections, immunities and benefits given to the Trustee,
including, without limitation, its right to be indemnified, are extended to, and shall be
enforceable by, the Trustee in each of its capacities hereunder, and each agent, custodian and
other Person employed to act hereunder.

          (k) The Trustee may request that the Company deliver a certificate setting forth the names of
individuals and/or titles of officers authorized at such time to take specified actions pursuant to
this Indenture.

     SECTION 7.03. INDIVIDUAL RIGHTS OF TRUSTEE.

     The Trustee in its individual or any other capacity may become the owner or pledgee of
Securities and may otherwise deal with the Company or any Affiliate of the Company with the same
rights it would have if it were not Trustee. However, in the event that the Trustee acquires any
conflicting interest (within the meaning of TIA § 310(b)) it must eliminate such conflicting
interest within 90 days after Default, apply to the SEC for permission to continue as trustee, or
resign. Any Agent may do the same with like rights and duties.

     SECTION 7.04. TRUSTEE’S DISCLAIMER.

     The Trustee shall not be responsible for and makes no representation as to the validity or
adequacy of this Indenture or the Securities; it shall not be accountable for the Company’s use of
the proceeds from the Securities or any money paid to the Company or upon the Company’s direction
under any provision of this Indenture; it shall not be responsible for the use or application of
any money received by any Paying Agent other than the Trustee; and it shall not be responsible for
any statement or recital herein or any statement in the Securities or any other document in
connection with the sale of the Securities or pursuant to this Indenture other than its certificate
of authentication.

     SECTION 7.05. NOTICE OF DEFAULTS.

     If a Default or Event of Default occurs and is continuing and if a Responsible Officer of the
Trustee has actual knowledge of such Default or Event of Default, the Trustee shall mail to Holders
of Securities a notice of the Default or Event of Default within 90 days after it occurs. Except
in the case of a Default or Event of Default in payment of principal of, or interest on, any
Security, the Trustee may withhold the notice if and so long as a committee of its Responsible
Officers in good faith determines that withholding the notice is in the interests of the Holders of
the Securities.

33

 

     SECTION 7.06. REPORTS BY TRUSTEE TO HOLDERS OF THE SECURITIES.

     On or before May 15 of each year, beginning with the May 15 following the date on which
Securities are first issued under this Indenture, and for so long as Securities remain outstanding,
the Trustee shall mail to the Holders of the Securities a brief report dated as of such reporting
date that complies with TIA § 313(a) (but if no event described in TIA § 313(a) has occurred within
the twelve months preceding the reporting date, no report need be transmitted). The Trustee also
shall comply with TIA § 313(b)(2). The Trustee shall also transmit by mail all reports as
required by TIA § 313(c). A copy of each report at the time of its mailing to the Holders of
Securities shall be mailed to the Company and filed with the SEC and each stock exchange on which
the Securities are listed in accordance with TIA § 313(d). The Company shall promptly notify the
Trustee when the Securities are listed on any stock exchange and any delisting thereof.

     SECTION 7.07. COMPENSATION AND INDEMNITY.

     The Company shall pay to the Trustee from time to time such compensation for its acceptance of
this Indenture and services hereunder as the Company and Trustee have separately agreed. 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 promptly upon request for all reasonable
disbursements, advances and expenses incurred or made by it in addition to the compensation for its
services, except to the extent any disbursement, advance or expense may be attributable to its
negligence or willful misconduct. Such expenses shall include the reasonable compensation,
disbursements and expenses of the Trustee’s agents and counsel.

     The Company shall indemnify the Trustee against any and all losses, liabilities or expenses
incurred by it arising out of or in connection with the acceptance or administration of its duties
under this Indenture, including the reasonable costs and expenses of enforcing this Indenture
against the Company (including this Section 7.07) and defending itself against any claim (whether
asserted by the Company or any Holder or any other person) or liability in connection with the
exercise or performance of any of its powers or duties hereunder, except to the extent any such
loss, liability or expense may be attributable to its negligence or willful misconduct. The
Trustee shall notify the Company promptly of any claim for which it may seek indemnity. Failure by
the Trustee to so notify the Company shall not relieve the Company of its obligations hereunder.
The Company shall defend the claim, and 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, which consent shall
not be unreasonably withheld.

     The obligations of the Company under this Section 7.07 shall survive the satisfaction and
discharge of this Indenture, and the removal or resignation of the Trustee.

     To secure the Company’s payment obligations in this Section, the Trustee shall have a lien
prior to the Securities on all money or property held or collected by the Trustee, except for those
funds that are held in trust to pay principal of, premium, if any, and interest on particular
Securities. Such lien shall survive the satisfaction and discharge of this Indenture.

34

 

     Without limiting any rights available to the Trustee under applicable law, when the Trustee
incurs expenses or renders services after an Event of Default specified in Section 6.01(e) or (f)
hereof occurs, the expenses and the compensation for the services (including the fees and expenses
of its agents and counsel) are intended to constitute expenses of administration under any
Bankruptcy Law.

     SECTION 7.08. REPLACEMENT OF TRUSTEE.

     A resignation or removal of the Trustee and appointment of a successor Trustee shall become
effective only upon the successor Trustee’s acceptance of appointment as provided in this Section.

     The Trustee may resign with respect to one or more or all series of Securities at any time and
be discharged from the trust hereby created by so notifying the Company in writing. The Holders of
a majority in principal amount of the then outstanding Securities of any series may remove the
Trustee with respect to such series by so notifying the Trustee and the Company in writing. The
Company may remove the Trustee if:

          (a) the Trustee ceases to be eligible in accordance with Section 7.10 hereof;

          (b) the Trustee is adjudged bankrupt or insolvent or an order for relief is entered with
respect to the Trustee under any Bankruptcy Law;

          (c) a custodian or public officer takes charge of the Trustee or its property; or

          (d) the Trustee becomes incapable of acting.

     If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any
reason, the Company shall promptly appoint a successor Trustee. Within one year after the
successor Trustee takes office, the Holders of a majority in principal amount of the then
outstanding Securities of a series may appoint a successor Trustee to replace the successor Trustee
appointed by the Company with respect to that series of Securities.

     If a successor Trustee does not take office within 60 days after the retiring Trustee resigns
or is removed, the retiring Trustee, the Company, or the Holders of at least 10% in principal
amount of the then outstanding Securities may petition any court of competent jurisdiction for the
appointment of a successor Trustee.

     If the Trustee, after written request by any Holder of a Security who has been a Holder of a
Security for at least six months, ceases to be eligible in accordance with Section 7.10, such
Holder of a Security may petition any court of competent jurisdiction for the removal of the
Trustee and the appointment of a successor Trustee.

     A successor Trustee shall deliver a written acceptance of its appointment to the retiring
Trustee and to the Company. Thereupon, the resignation or removal of the retiring Trustee shall
become effective, and the successor Trustee shall have all the rights, powers and duties of the
Trustee under this Indenture. The successor Trustee shall mail a notice of its succession to
Holders of the Securities. The retiring Trustee shall promptly transfer all property held by it as

35

 

Trustee to the successor Trustee; PROVIDED all sums owing to the Trustee hereunder have been
paid and subject to the lien provided for in Section 7.07 hereof. Notwithstanding replacement of
the Trustee pursuant to this Section 7.08, the Company’s obligations under Section 7.07 hereof
shall continue for the benefit of the retiring Trustee.

     If a successor Trustee is appointed with respect to the Securities of one or more (but not
all) series, the Company, the retiring Trustee and each successor Trustee with respect to the
Securities of any applicable series shall execute and deliver an indenture supplemental hereto
which shall contain such provisions as shall be deemed necessary or desirable to confirm that all
the rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of any
series as to which the predecessor Trustee is not retiring shall continue to be vested in the
predecessor Trustee, and shall add to or change any of the provisions of this Indenture as shall be
necessary to provide for or facilitate the administration of the trusts hereunder by more than one
Trustee, it being understood that nothing herein or in such supplemental indenture shall constitute
such Trustees as 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.

     SECTION 7.09. SUCCESSOR TRUSTEE BY MERGER, ETC.

     If the Trustee consolidates, merges or converts into, or transfers all or substantially all of
its corporate trust business to, another corporation, the successor corporation without any further
act shall be the successor Trustee.

     SECTION 7.10. ELIGIBILITY; DISQUALIFICATION.

     There shall at all times be a Trustee hereunder that is a corporation organized and doing
business under the laws of the United States of America or of any state thereof that is authorized
under such laws to exercise corporate trust powers, that is subject to supervision or examination
by federal or state authorities and that has a combined capital and surplus of at least $50,000,000
as set forth in its most recent published annual report of condition.

     This Indenture shall always have a Trustee who satisfies the requirements of TIA § 310(a)(1),
(2) and (5). The Trustee is subject to TIA § 310(b); provided, however, that
there shall be excluded from the operation of TIA §310(b)(1) any indenture or indentures under
which other securities or certificates of interest or participation in other securities of the
Company are outstanding if the requirements for such exclusion set forth in TIA §310(b)(1) are met.

     SECTION 7.11. PREFERENTIAL COLLECTION OF CLAIMS AGAINST COMPANY.

     The Trustee is subject to TIA § 311(a), excluding any creditor relationship described in TIA §
311(b). A Trustee who has resigned or been removed shall be subject to TIA § 311(a) to the extent
indicated therein.

ARTICLE 8

LEGAL DEFEASANCE AND COVENANT DEFEASANCE

     SECTION 8.01. OPTION TO EFFECT LEGAL DEFEASANCE OR COVENANT DEFEASANCE.

          (a) The Company may, at the option of its Board of Directors evidenced by a resolution set
forth in an Officers’ Certificate, at any time, elect to have either Section 8.02 or 8.03 hereof,
with such modifications thereto as may be specified in the Board Resolution or supplemental
indenture establishing a particular series of Securities, be applied to all outstanding Securities
of one or more series upon compliance with the conditions set forth below in this Article 8.

          (b) As an alternative to having Section 8.02 or 8.03 be applied to all outstanding Securities
of one or more series, the Company may terminate its obligations under the Securities of one or
more series and its obligations under this Indenture in respect of such series of Securities
(except those obligations referred to in the penultimate paragraph of this Section 8.01(b), and any
obligation of the Company to convert or exchange Securities of such series as expressly provided
for in the Board Resolution or indenture supplemental hereto establishing such Series) (1) if (i)
all Securities of such series theretofore authenticated and delivered (except lost, stolen or
destroyed Securities that have been replaced or paid and Securities for whose payment cash in
United States dollars 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 8.06) have been delivered to the Trustee for cancellation; (ii) the Company has paid all
sums payable by it hereunder or under the applicable Board Resolution or indenture supplemental
hereto in respect of such series of Securities; and (iii) the Company shall have delivered to the
Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions
precedent relating to the satisfaction and discharge of this Indenture with respect to such series
have been complied with; or (2) if (i) either (A) in the case of a series of Securities redeemable
prior to its Stated Maturity, such Securities are to be called for redemption within one year under
arrangements satisfactory to the Trustee for the giving of notice of redemption by the Trustee in
the name, and at the expense, of the Company or (B) all Securities of such series have otherwise
become due and payable hereunder or will become due and payable within one year; (ii) the Company
shall have irrevocably deposited or caused to be deposited with the Trustee (or a trustee
satisfactory to the Trustee, under the terms of an irrevocable trust agreement in form and
substance satisfactory to the Trustee), as trust funds in trust solely for the benefit of the
Holders of Securities of such series for that purpose, cash in United States dollars in such amount
as is sufficient without consideration of reinvestment of interest or other earnings on such cash,
to pay the entire indebtedness on such Securities not theretofore delivered to the Trustee for
cancellation, for the principal of, premium, if any, and interest on the outstanding Securities of
such series 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; (iii) no Default or
Event of Default with respect to this Indenture or the Securities shall have occurred and be
continuing on the date of such deposit or shall occur as a result of such deposit and such deposit
will not result in a breach or violation of, or constitute a default under, any other instrument to
which the Company is bound; (iv) the Company shall have paid all other sums payable by it hereunder
in respect of Securities of such series; and (v) the

37

 

Company shall have delivered to the Trustee an Officers’ Certificate and an Opinion of
Counsel, each stating that all conditions precedent relating to the satisfaction and discharge of
this Indenture have been complied with.

     Notwithstanding the foregoing paragraph, the Company’s obligations in Sections 2.07, 2.08,
2.09, 2.10, 4.02, 7.07, 8.06 and 8.07 shall survive with respect to the Securities of the
applicable series until they are no longer outstanding pursuant to the last paragraph of Section
2.10. After the Securities of the applicable series are no longer outstanding, the Company’s
obligations in Sections 7.07, 8.06 and 8.07 shall survive in respect of Securities of the
applicable series.

     After such delivery or irrevocable deposit, the Trustee upon request shall acknowledge in
writing the discharge of the Company’s obligations under the Securities of the applicable series
and the Company’s obligations under this Indenture with respect to the Securities of such series,
except for those surviving obligations specified above.

     SECTION 8.02. LEGAL DEFEASANCE AND DISCHARGE.

     Upon the Company’s exercise under Section 8.01 hereof of the option applicable to this Section
8.02 relating to one or more series of Securities, the Company shall, upon the satisfaction of the
conditions set forth in Section 8.04 hereof, be deemed to have been discharged from its obligations
with respect to all outstanding Securities of such series on the date the conditions set forth
below are satisfied (hereinafter, “LEGAL DEFEASANCE”). For this purpose, Legal Defeasance means
that the Company shall be deemed to have paid and discharged the entire indebtedness represented by
the outstanding Securities of the applicable series, which shall thereafter be deemed to be
“OUTSTANDING” only for the purposes of Section 8.05 hereof and the other Sections of this Indenture
referred to in (a) and (b) below, and to have satisfied all of its other obligations under the
Securities of the applicable series and under the provisions of this Indenture applicable to such
series (and the Trustee, on demand of and at the expense of the Company, shall execute proper
instruments acknowledging the same), except for the following provisions which shall survive until
otherwise terminated or discharged hereunder: (a) the rights of Holders of outstanding Securities
of the applicable series to receive solely from the trust fund described in Section 8.04 hereof,
and as more fully set forth in such Section, payments in respect of the principal of, premium, if
any, and interest, on such Securities when such payments are due, (b) the Company’s obligations
with respect to such Securities under Article 2 and Section 4.02 hereof, (c) the rights, powers,
trusts, duties and immunities of the Trustee hereunder, and the Company’s obligations in connection
therewith and (d) this Article 8. Subject to compliance with this Article 8, the Company may
exercise its option under this Section 8.02 notwithstanding the prior exercise of its option under
Section 8.03 hereof.

     SECTION 8.03. COVENANT DEFEASANCE.

     Upon the Company’s exercise under Section 8.01 hereof of the option applicable to this Section
8.03 relating to one or more series of Securities, the Company shall, upon the satisfaction of the
conditions set forth in Section 8.04 hereof, be released from its obligations under the covenants
contained in Section 4.06 hereof with respect to the outstanding Securities of the applicable
series, and under any other covenants specified in the supplemental indenture or other

38

 

terms of the applicable series as covenants to which this Section 8.03 apply, on and after the
date the conditions set forth below are satisfied (hereinafter, “COVENANT DEFEASANCE”), and the
Securities of the applicable series shall thereafter be deemed 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 such covenants, but shall continue to be deemed “OUTSTANDING” for all
other purposes hereunder (it being understood that the Securities of the applicable series shall
not be deemed outstanding for accounting purposes). For this purpose, Covenant Defeasance means
that, with respect to the “OUTSTANDING” Securities of the applicable series, the Company may omit
to comply with and shall have no liability in respect of any term, condition or limitation set
forth in any such covenant, whether directly or indirectly, by reason of any reference elsewhere
herein to any such covenant or by reason of any reference in any such covenant to any other
provision herein or in any other document and such omission to comply shall not constitute a
Default or an Event of Default under Section 6.01 hereof, but, except as specified above, the
remainder of this Indenture and such Securities shall be unaffected thereby.

     SECTION 8.04. CONDITIONS TO LEGAL OR COVENANT DEFEASANCE.

     The following shall be the conditions to the application of either Section 8.02 or 8.03 hereof
to the outstanding Securities of one or more series:

     In order to exercise either Legal Defeasance or Covenant Defeasance:

          (a) the Company must irrevocably deposit with the Trustee ,(or another trustee (satisfactory
to the Trustee) satisfying the requirements of Section 7.10, who shall agree under the terms of an
irrevocable trust agreement in form and substance satisfactory to the Trustee to comply with the
provisions of this Article 8 applicable to it) in trust, for the benefit of the Holders of the
Securities of the applicable series, (i) an amount of cash in United States dollars, (ii)
non-callable U.S. Government Obligations which, through scheduled payment of principal and interest
in respect thereof in accordance with their terms, will provide, not later than one Business Day
before the due date of any payment of principal of, premium, if any, or interest on the Securities
of such series, cash in an amount, or (iii) a combination thereof, sufficient, in the written
opinion of a nationally recognized firm of independent public accountants delivered to the Trustee,
to pay the principal of, interest and premium, if any, on the outstanding Securities of the
applicable series on the Stated Maturity or on the applicable redemption date, as the case may be,
and any mandatory sinking fund payments applicable to the Securities of such series on the day on
which such payments are due, and the Company must specify whether the Securities of the applicable
series are being defeased to maturity or to a particular redemption date;

          (b) in the case of an election under Section 8.02 hereof, the Company shall have delivered to
the Trustee an Opinion of Counsel in the United States reasonably acceptable to the Trustee
confirming 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 this Indenture, there has been a change in the
applicable federal income tax law, in either case to the effect that, and based thereon such
Opinion of Counsel shall confirm that, the Holders of the outstanding Securities of the applicable
series will not recognize income, gain or loss for federal income tax purposes as a

39

 

result of such Legal 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 Legal Defeasance had
not occurred;

          (c) in the case of an election under Section 8.03 hereof, the Company shall have delivered to
the Trustee an Opinion of Counsel in the United States reasonably acceptable to the Trustee
confirming that the Holders of the outstanding Securities of the applicable series will not
recognize income, gain or loss for federal income tax purposes as a result of such Covenant
Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at
the same times as would have been the case if such Covenant Defeasance had not occurred;

          (d) no Default or Event of Default shall have occurred and be continuing on the date of such
deposit (other than a Default or Event of Default resulting from the borrowing of funds to be
applied to such deposit) or insofar as Sections 6.01(e) or (f) hereof are concerned, at any time in
the period ending on the 91st day after the date of deposit (or greater period of time in which any
such deposit of trust funds may remain subject to bankruptcy or insolvency laws insofar as those
apply to the deposit by the Company); and

          (e) the Company shall have delivered to the Trustee an Officers’ Certificate and an Opinion of
Counsel, each stating that all conditions precedent provided for or relating to the Legal
Defeasance or the Covenant Defeasance have been complied with.

     SECTION 8.05. DEPOSITED MONEY AND U.S. GOVERNMENT OBLIGATIONS TO BE HELD IN TRUST; OTHER
MISCELLANEOUS PROVISIONS.

     Subject to Section 8.06 hereof, all money and non-callable U.S. Government Obligations
(including the proceeds thereof) deposited with the Trustee (or other qualifying trustee,
collectively for purposes of this Section 8.05, the “TRUSTEE”) pursuant to Section 8.04 hereof in
respect of the outstanding Securities of the applicable series shall be held in trust and applied
by the Trustee, in accordance with the provisions of such Securities and this Indenture, to the
payment, either directly or through any Paying Agent (including the Company acting as Paying Agent)
as the Trustee may determine, to the Holders of such Securities of all sums due and to become due
thereon in respect of principal, premium, if any, and interest, but such money need not be
segregated from other funds except to the extent required by law.

     The Company shall pay and indemnify the Trustee against any tax, fee or other charge imposed
on or assessed against the cash or non-callable U.S. Government Obligations deposited pursuant to
Section 8.04 hereof or the principal and interest received in respect thereof other than any such
tax, fee or other charge which by law is for the account of the Holders of the outstanding
Securities of the applicable series.

     Anything in this Article 8 to the contrary notwithstanding, the Trustee shall deliver or pay
to the Company from time to time upon the request of the Company any money or non-callable U.S.
Government Obligations held by it as provided in Section 8.04 hereof which, in the opinion of a
nationally recognized firm of independent public accountants expressed in a written

40

 

certification thereof delivered to the Trustee (which may be the opinion delivered under
Section 8.04(a) hereof), are in excess of the amount thereof that would then be required to be
deposited to effect an equivalent Legal Defeasance or Covenant Defeasance of the applicable series.

     SECTION 8.06. REPAYMENT TO COMPANY.

     Any money and U.S. Government Obligations deposited with the Trustee or any Paying Agent, or
then held by the Company, in trust for the payment of the principal of, premium or interest on any
Security and remaining unclaimed for two years after such principal, and premium, if any, or
interest has become due and payable shall be paid to the Company on its request or (if then held by
the Company) shall be discharged from such trust; and the Holder of such Security shall thereafter
look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent
with respect to such money and U.S. Government Obligations, and all liability of the Company as
trustee thereof, shall thereupon cease; PROVIDED, HOWEVER, that the Trustee or such Paying Agent,
before being required to make any such repayment, may at the expense of the Company cause to be
published once, in the NEW YORK TIMES and THE WALL STREET JOURNAL (national edition), notice that
such money remains unclaimed and that, after a date specified therein, which shall not be less than
30 days from the date of such notification or publication, any unclaimed balance of such money then
remaining will be repaid to the Company.

     SECTION 8.07. REINSTATEMENT.

     If the Trustee or Paying Agent is unable to apply any United States dollars or non-callable
U.S. Government Obligations deposited pursuant to Section 8.02 or 8.03 hereof, as the case may be,
by reason of any order or judgment of any court or governmental authority enjoining, restraining or
otherwise prohibiting such application, then the obligations of the Company under this Indenture
and the Securities shall be revived and reinstated as though no deposit had occurred pursuant to
Section 8.02 or 8.03 hereof until such time as the Trustee or Paying Agent is permitted to apply
all such money in accordance with Section 8.02 or 8.03 hereof, as the case may be; PROVIDED,
HOWEVER, that if the Company makes any payment of principal of, premium or interest on any Security
following the reinstatement of its obligations, the Company shall be subrogated to the rights of
the Holders of such Securities to receive such payment from the money held by the Trustee or Paying
Agent.

ARTICLE 9

AMENDMENT, SUPPLEMENT AND WAIVER

     SECTION 9.01. WITHOUT CONSENT OF HOLDERS OF SECURITIES.

     Notwithstanding Section 9.02 of this Indenture, the Company and the Trustee may amend or
supplement this Indenture or the Securities without the consent of any Holder of a Security:

          (a) to evidence the succession of another Person to the Company, or successive successions,
and the assumption by the successor Person of the covenants, agreements and obligations of the
Company pursuant to Article 5 hereof;

41

 

          (b) to add to the covenants of the Company such further covenants, restrictions or conditions
for the protection of the Holders of all or any series of Securities (and if such covenants are to
be for the benefit of less than all series of Securities stating that such covenants are expressly
being included for the benefit of such series) as the Board of Directors and the Trustee shall
consider to be for the protection of the Holders of such Securities, and to make the occurrence, or
the occurrence and continuance, of a default in any of such additional covenants, restrictions or
conditions a default or an Event of Default permitting the enforcement of all or any of the several
remedies provided in this Indenture as herein set forth; PROVIDED, HOWEVER, that in respect of any
such additional covenant, restriction or condition such supplemental indenture may provide for a
particular period of grace after default (which period may be shorter or longer than that allowed
in the case of other defaults) or may provide for an immediate enforcement upon such default or may
limit the remedies available to the Trustee upon such default;

          (c) to provide for the issuance under this Indenture of Securities in coupon form (including
Securities registrable as to principal only) and to provide for exchangeability of such Securities
with the Securities issued hereunder in fully registered form and to make all appropriate changes
for such purpose;

          (d) to cure any ambiguity or to correct or supplement any provision contained herein or in any
supplemental indenture which may be defective or inconsistent with any other provision contained
herein or in any supplemental indenture, or to make such other provisions in regard to matters or
questions arising under this Indenture; PROVIDED that any such action shall not adversely affect in
any material respect the interests of the Holders of the Securities;

          (e) to evidence and provide for the acceptance of appointment hereunder by a successor Trustee
with respect to the Securities of one or more series and to add to or change any of the provisions
of this Indenture as shall be necessary to provide for or facilitate the administration of the
trusts hereunder by more than one trustee, pursuant to the requirements of Section 7.08;

          (f) to make any change that does not adversely affect in any material respect the interests of
any Holder;

          (g) to provide for the issuance of and establish the form and terms and conditions of the
Securities of any series, to establish the form of any certifications required to be furnished
pursuant to the terms of this Indenture or any series of Securities or to add to the rights of the
Holders of any series of Securities; or

          (h) to comply with the requirements of the SEC in order to effect or maintain the
qualification of the Indenture under the TIA.

     Upon the request of the Company accompanied by a copy of a Board Resolution, certified by the
Secretary or an Assistant Secretary of the Company to have been duly adopted by the Board of
Directors and to be in full force and effect on the date of the certificate, authorizing the
execution of any such amended or supplemental indenture, and upon receipt by the Trustee of the
documents described in Sections 7.02(b), 9.06 and 12.05 hereof, the Trustee shall join with

42

 

the Company in the execution of any amended or supplemental indenture authorized or permitted
by the terms of this Indenture and to make any further appropriate agreements and stipulations that
may be therein contained, but the Trustee shall not be obligated to enter into such amended or
supplemental indenture that affects its own rights, duties or immunities under this Indenture or
otherwise.

     SECTION 9.02. WITH CONSENT OF HOLDERS OF SECURITIES.

     Except as provided below in this Section 9.02, the Company and the Trustee may amend or
supplement this Indenture, or the Securities of any series may be amended or supplemented, with the
consent of the Holders of a majority in principal amount of the Securities then outstanding of all
series affected by such supplemental indenture (voting as a single class) (including, without
limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer
for, Securities), and, subject to Sections 6.04 and 6.07 hereof, any existing Default or Event of
Default (other than a Default or Event of Default in the payment of the principal of, premium or
interest on the Securities) or compliance with any provision of this Indenture or the Securities of
such series may be waived with the consent of the Holders of a majority in principal amount of the
Securities then outstanding of all series affected by such waiver (voting as a single class)
(including, without limitation, consents obtained in connection with a purchase of, or tender offer
or exchange offer for the Securities).

     Upon the request of the Company accompanied by a copy of a Board Resolution, certified by the
Secretary or an Assistant Secretary of the Company to have been duly adopted by the Board of
Directors and to be in full force and effect on the date of the certificate, authorizing the
execution of any such amended or supplemental indenture, and upon the filing with the Trustee of
evidence satisfactory to the Trustee of the consent of the Holders of Securities of each such
series as aforesaid, and upon receipt by the Trustee of the documents described in Sections
7.02(b), 9.06 and 12.05 hereof, the Trustee shall join with the Company in the execution of such
amended or supplemental indenture unless such amended or supplemental indenture affects the
Trustee’s own rights, duties or immunities under this Indenture or otherwise, in which case the
Trustee may in its discretion, but shall not be obligated to, enter into such amended or
supplemental indenture.

     It shall not be necessary for the consent of the Holders of Securities under this Section 9.02
to approve the particular form of any proposed amendment or waiver, but it shall be sufficient if
such consent approves the substance thereof.

     After an amendment, supplement or waiver under this Section 9.02 becomes effective, the
Company shall mail to the Holders of Securities of each series affected thereby a notice briefly
describing the amendment, supplement or waiver. Any failure of the Company to mail such notice, or
any defect therein, shall not, however, in any way impair or affect the validity of any such
amended or supplemental indenture or waiver.

     However, without the consent of each Holder of Securities affected, an amendment or waiver may
not (with respect to any Securities held by a non-consenting Holder):

43

 

          (a) reduce the principal amount of the Securities whose Holders must consent to an amendment,
supplement or waiver;

          (b) reduce the principal of or change the fixed maturity of the principal of, premium, if any,
or mandatory sinking fund obligation, if any, with respect to any Securities of any series or alter
the provisions with respect to the redemption of the Securities;

          (c) reduce the rate of or change the time for payment of interest, including default interest,
on any Security of any series;

          (d) waive a Default or Event of Default in the payment of principal of or interest or premium
on the Securities of any series (except a rescission of acceleration of the Securities by the
Holders of a majority in aggregate principal amount of the Securities of one or more affected
series and a waiver of the payment default that resulted from such acceleration);

          (e) make any Security of any series payable in currency other than that stated in the
Securities of such series;

          (f) make any change in the provisions of this Indenture relating to waivers of past Defaults
or the rights of Holders of Securities to receive payments of principal of or interest or premium
on the Securities;

          (g) waive a redemption payment with respect to any Security; or

          (h) make any change in Section 6.04 or 6.07 hereof or in the amendment and waiver provisions
of Section 9.01 or this Section 9.02.

     SECTION 9.03. COMPLIANCE WITH TRUST INDENTURE ACT.

     Every amendment or supplement to this Indenture or the Securities shall be set forth in an
amended or supplemental indenture that complies with the TIA as then in effect.

     SECTION 9.04. REVOCATION AND EFFECT OF CONSENTS.

     Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder of a
Security is a continuing consent by the Holder of a Security and every subsequent Holder of a
Security or portion of a Security that evidences the same debt as the consenting Holder’s
Securities, even if notation of the consent is not made on any Securities. However, any such
Holder of a Security or subsequent Holder of a Security may revoke the consent as to its Securities
if the Trustee receives written notice of revocation before the date the waiver, supplement or
amendment becomes effective. An amendment, supplement or waiver becomes effective in accordance
with its terms and thereafter binds every Holder.

     SECTION 9.05. NOTATION ON OR EXCHANGE OF SECURITIES.

     The Trustee may place an appropriate notation about an amendment, supplement or waiver on any
Securities thereafter authenticated. The Company in exchange for all Securities

44

 

may issue and the Trustee shall authenticate new Securities that reflect the amendment,
supplement or waiver.

     Failure to make the appropriate notation or to issue new Securities shall not affect the
validity and effect of such amendment, supplement or waiver.

     SECTION 9.06. TRUSTEE TO SIGN AMENDMENTS, ETC.

     The Company may not sign an amendment or supplemental indenture until its Board of Directors
approves it. The Trustee shall sign any amendment or supplemental indenture authorized pursuant to
this Article 9 if the amendment or supplement does not adversely affect the rights, duties,
liabilities or immunities of the Trustee. If it does, the Trustee may, but need not, sign it. In
signing or refusing to sign such amendment or supplemental indenture, the Trustee shall be entitled
to receive and shall be fully protected in relying upon, an Officers’ Certificate and an Opinion of
Counsel as conclusive evidence that such amendment or supplemental indenture is authorized or
permitted by this Indenture, that it is not inconsistent herewith, and that it will be valid and
binding upon the Company in accordance with its terms.

     SECTION 9.07. AMENDMENTS TO SUBORDINATION PROVISIONS

     Any amendment to the provisions of Article 10 hereof will require the consent of each holder
of Senior Debt that would be adversely affected by such amendment.

ARTICLE 10

SUBORDINATION

     SECTION 10.01. AGREEMENT TO SUBORDINATE.

     (a) The Company agrees, and each Holder by accepting a Security agrees, that the indebtedness
evidenced by the Securities is subordinated in right of payment, to the extent and in the manner
provided in this Article, to the prior payment in full of all Senior Debt (whether outstanding on
the date hereof or hereafter created, incurred, assumed or guaranteed), and that the subordination
is for the benefit of the holders of Senior Debt.

     (b) If any holder of Senior Debt is required by any court or otherwise to return to the
Company, or any Custodian (as defined in Article 6 of this Indenture), trustee, or similar official
acting in relation to the Company, any amount paid by the Company to such holder of Senior Debt,
the provisions of this Article 10, to the extent theretofore discharged, shall be reinstated in
full force and effect; PROVIDED, HOWEVER, that any amounts paid pursuant to this Indenture to
Holders of Securities shall not be subject to disgorgement pursuant to the provisions of this
paragraph (b).

     SECTION 10.02. CERTAIN DEFINITIONS.

     “DESIGNATED SENIOR DEBT” means (i) the Senior Bank Debt and (ii) any other Senior Debt
permitted under this Indenture the principal amount of which is at least the amount specified in
the applicable supplemental indenture or Board Resolution and that has been designated by the
Company as “DESIGNATED SENIOR DEBT.”

45

 

     “REPRESENTATIVE” means the indenture trustee or other trustee, agent or representative for any
Senior Debt.

     A “distribution” may consist of cash, securities or other property, by set-off or otherwise.

     SECTION 10.03. LIQUIDATION; DISSOLUTION; BANKRUPTCY.

     Upon any distribution to creditors of the Company in a liquidation or dissolution of the
Company or in a bankruptcy, reorganization, insolvency, receivership or similar proceeding relating
to the Company or its property, an assignment for the benefit of creditors or any marshalling of
the Company’s assets and liabilities:

     (1) holders of Senior Debt shall be entitled to receive payment in full of all Obligations due
in respect of such Senior Debt (including interest after the commencement of any such proceeding at
the rate specified in the applicable Senior Debt) before the Holders of Securities shall be
entitled to receive any payment with respect to the Securities (except that Holders may receive (i)
securities that are subordinated to at least the same extent as the Securities to (a) Senior Debt
and (b) any securities issued in exchange for Senior Debt and (ii) payments and other distributions
made from any defeasance trust created pursuant to Section 8.05 hereof); and

     (2) until all Obligations with respect to Senior Debt (as provided in subsection (1) above)
are paid in full, any distribution to which the Holders of Securities would be entitled but for
this Article shall be made to holders of Senior Debt (except that Holders may receive (i)
securities that are subordinated to at least the same extent as the Securities to (a) Senior Debt
and (b) any securities issued in exchange for Senior Debt and (ii) payments and other distributions
made from any defeasance trust created pursuant to Section 8.05 hereof), as their interests may
appear.

     SECTION 10.04. DEFAULT ON DESIGNATED SENIOR DEBT.

          (a) The Company may not make any payment or distribution to the Trustee or any Holder in
respect of the Securities and may not acquire from the Trustee or any Holder any Securities for
cash or property (other than (1) securities that are subordinated to at least the same extent as
the Securities to (A) Senior Debt and (B) any securities issued in exchange for Senior Debt and (2)
payments and other distributions made from any defeasance trust created pursuant to Section 8.05
hereof) until all principal and other Obligations with respect to the Senior Debt have been paid in
full if:

     (1) a default in the payment of the principal of, premium, if any, or interest on
Designated Senior Debt occurs and is continuing beyond any applicable grace period in the
agreement, indenture or other document governing such Designated Senior Debt; or

     (2) a default, other than a default specified in Section 10.04(a)(1), on Designated
Senior Debt occurs and is continuing with respect to Designated Senior Debt that then
permits holders of the Designated Senior Debt as to which such default relates to accelerate
its maturity and the Trustee receives a notice of the default (a “PAYMENT

46

 

BLOCKAGE NOTICE”) from a Person who may give it pursuant to Section 10.12 hereof. If
the Trustee receives any such Payment Blockage Notice, no subsequent Payment Blockage Notice
shall be effective for purposes of this Section unless and until (I) at least 360 days shall
have elapsed since the effectiveness of the immediately prior Payment Blockage Notice and
(II) all scheduled payments of principal and premium, if any, and interest on the Securities
that have come due (other than by reason of acceleration) have been paid in full in cash.
No default described in this paragraph (2) that existed or was continuing on the date of
delivery of any Payment Blockage Notice to the Trustee shall be, or be made, the basis for a
subsequent Payment Blockage Notice.

          (b) The Company may and shall resume payments on and distributions in respect of the
Securities and may acquire them:

     (i) in the case of a default described in Section 10.04(a)(1), upon the date on
which the default is cured or waived,

     (ii) in the case of a default referred to in Section 10.04(a)(2) hereof, the
earlier of the date on which such default is cured or waived or 179 days after the
date on which the applicable Payment Blockage Notice is received, unless the
maturity of any Designated Senior Debt has been accelerated, and

     (iii) if this Article otherwise permits the payment, distribution or
acquisition at the time of such payment, distribution or acquisition.

     SECTION 10.05. ACCELERATION OF SECURITIES.

     If payment of the Securities is accelerated because of an Event of Default, the Company shall
promptly notify holders of Senior Debt of the acceleration.

     SECTION 10.06. WHEN DISTRIBUTION MUST BE PAID OVER.

     In the event that the Trustee or any Holder receives any payment of any Obligations with
respect to the Securities at a time when a Responsible Officer of the Trustee or such Holder, as
applicable, has actual knowledge that such payment is prohibited by Section 10.04 hereof, such
payment shall be held by the Trustee or such Holder, in trust for the benefit of, and shall be paid
forthwith over and delivered, upon written request, to, the holders of Senior Debt as their
interests may appear or their Representative under the indenture or other agreement (if any)
pursuant to which Senior Debt may have been issued, as their respective interests may appear, for
application to the payment of all Obligations with respect to Senior Debt remaining unpaid to the
extent necessary to pay such Obligations in full in accordance with their terms, after giving
effect to any concurrent payment or distribution to or for the holders of Senior Debt.

     With respect to the holders of Senior Debt, the Trustee undertakes to perform only such
obligations on the part of the Trustee as are specifically set forth in this Article 10, and no
implied covenants or obligations with respect to the holders of Senior Debt shall be read into this
Indenture against the Trustee. The Trustee shall not be deemed to owe any fiduciary duty to the
holders of Senior Debt, and shall not be liable to any such holders if the Trustee shall pay over
or distribute to or on behalf of Holders or the Company or any other Person money or assets to

47

 

which any holders of Senior Debt shall be entitled by virtue of this Article 10, except if
such payment is made as a result of the willful misconduct or gross negligence of the Trustee.

     SECTION 10.07. NOTICE BY COMPANY.

     The Company shall promptly notify the Trustee and the Paying Agent of any facts known to the
Company that would cause a payment of any Obligations with respect to the Securities to violate
this Article, but failure to give such notice shall not affect the subordination of the Securities
to the Senior Debt as provided in this Article.

     SECTION 10.08. SUBROGATION.

     After all Senior Debt is paid in full and until the Securities are paid in full, Holders shall
be subrogated (equally and ratably with all other Indebtedness pari passu with the Securities) to
the rights of holders of Senior Debt to receive distributions applicable to Senior Debt to the
extent that distributions otherwise payable to the Holders have been applied to the payment of
Senior Debt. A distribution made under this Article to holders of Senior Debt that otherwise would
have been made to Holders is not, as between the Company and Holders, a payment by the Company on
the Senior Debt.

     SECTION 10.09. RELATIVE RIGHTS.

     This Article defines the relative rights of Holders and holders of Senior Debt. Nothing in
this Indenture shall:

          (a) impair, as between the Company and Holders, the obligation of the Company, which is
absolute and unconditional, to pay principal of, premium, if any, and interest on the Securities in
accordance with their terms;

          (b) affect the relative rights of Holders and creditors of the Company other than rights of
Holders of the Securities in relation to holders of Senior Debt; or

          (c) prevent the Trustee or any Holder from exercising its available remedies upon a Default or
Event of Default, subject to the rights of holders and owners of Senior Debt to receive
distributions and payments otherwise payable to Holders.

     If the Company fails because of this Article to pay principal of, premium, if any, or interest
on a Security on the due date, the failure is still a Default or Event of Default.

     SECTION 10.10. SUBORDINATION MAY NOT BE IMPAIRED BY COMPANY.

     No right of any holder of Senior Debt to enforce the subordination of the indebtedness
evidenced by the Securities shall be impaired by any act or failure to act by the Company or any
Holder or by the failure of the Company or any Holder to comply with this Indenture.

48

 

     SECTION 10.11. DISTRIBUTION OR NOTICE TO REPRESENTATIVE.

     Whenever a distribution is to be made or a notice given to holders of Senior Debt, the
distribution may be made and the notice given to their Representative.

     Upon any payment or distribution of assets of the Company referred to in this Article 10, the
Trustee and the Holders shall be entitled to rely upon any order or decree made by any court of
competent jurisdiction or upon any certificate of such Representative (or of any holder of Senior
Debt for which there is no Representative) or of the liquidating trustee or agent or other Person
making any distribution to the Trustee or to the Holders for the purpose of ascertaining the
Persons entitled to participate in such distribution, the holders of the Senior Debt and other
Indebtedness of the Company, the amount thereof or payable thereon, the amount or amounts paid or
distributed thereon and all other facts pertinent thereto or to this Article 10. In the event that
the Trustee determines, in good faith, that further evidence is required with respect to the right
of any Person as a holder of Senior Debt to participate in any payment or distribution pursuant to
this Article 10, the Trustee may request such Person to furnish evidence to the reasonable
satisfaction of the Trustee as to the amount of Senior Debt held by such Person, the extent to
which such Person is entitled to participate in such payment or distribution and other facts
pertinent to the rights of such Person under this Article 10 and, if such evidence is not
furnished, the Trustee may defer any payment to such Person pending judicial determination as to
the right of such Person to receive such payment.

     SECTION 10.12. RIGHTS OF TRUSTEE AND PAYING AGENT.

     Notwithstanding the provisions of this Article 10 or any other provision of this Indenture,
the Trustee shall not be charged with knowledge of the existence of any facts that would prohibit
the making of any payment or distribution by the Trustee, and the Trustee and any Paying Agent may
continue to make payments on the Securities, unless the Trustee shall have received at the
Corporate Trust Office of the Trustee at least five Business Days prior to the date of such payment
written notice of facts that would cause the payment of any Obligations with respect to the
Securities to violate this Article or a Responsible Officer of the Trustee otherwise has actual
knowledge of such facts. Only the Company or a Representative may give the notice, such notice
from the Company to be in the form of an Officers’ Certificate. Notwithstanding the provisions of
this Article 10 or any other provisions of this Indenture, the Trustee shall not be charged with
knowledge of the existence of any facts that would permit the resumption of payments on or
distributions in respect of the Securities or the acquisition of the Securities by the Company
unless the Trustee shall have received an Officers’ Certificate or a notice from a Representative
to the effect that such resumption is permitted. Nothing in this Article 10 shall impair the
claims of, or payments to, the Trustee under or pursuant to Section 7.07 hereof.

     The Trustee in its individual or any other capacity may hold Senior Debt with the same rights
it would have if it were not Trustee. Any Agent may do the same with like rights.

     SECTION 10.13. AUTHORIZATION TO EFFECT SUBORDINATION.

     Each Holder of a Security by the Holder’s acceptance thereof authorizes and directs the
Trustee on the Holder’s behalf to take such action as may be necessary or appropriate to effectuate
the subordination as provided in this Article 10, and appoints the Trustee to act as the Holder’s
attorney-in-fact for any and all such purposes. If the Trustee does not file a proper

49

 

proof of claim or proof of debt in the form required in any proceeding referred to in Section
6.09 hereof at least 30 days before the expiration of the time to file such claim, the agent under
the Credit Facility (or in the absence of such agent, the lender thereunder) is hereby authorized
to file an appropriate claim for and on behalf of the Holders of the Securities.

ARTICLE 11

     SECTION 11.01. PURPOSES FOR WHICH MEETING MAY BE CALLED.

     A meeting of Holders of Securities of any series may be called at any time and from time to
time pursuant to this Article 11 to make, give or take any request, demand, authorization,
direction, notice, consent, waiver or other action provided by this Indenture to be made, given or
taken by Holders of Securities of such series.

     SECTION 11.02. CALL, NOTICE AND PLACE OF MEETINGS.

          (a) The Trustee may at any time call a meeting of Holders of Securities of any series for any
purpose specified in Section 11.01, to be held at such time and at such place in the Borough of
Manhattan, The City of New York, or in such other place as the Trustee shall determine. Notice of
every meeting of Holders of Securities of any series, setting forth the time and the place of such
meeting and in general terms the action proposed to be taken at such meeting, shall be given, in
the manner provided in Section 12.02, not less than 20 nor more than 180 days prior to the date
fixed for the meeting.

          (b) In case at any time the Company, by or pursuant to a Board Resolution, or the Holders of
at least 25% in principal amount of the outstanding Securities of any series shall have requested
the Trustee to call a meeting of the Holders of Securities of such series for any purpose specified
in Section 11.01 by written request setting forth in reasonable detail the action proposed to be
taken at the meeting, and the Trustee shall not have mailed notice of such meeting within 20 days
after receipt of such request or shall not thereafter proceed to cause the meeting to be held as
provided herein, then the Company or the Holders of Securities of such series in the amount above
specified, as the case may be, may determine the time and the place for such meeting and may call
such meeting for such purposes by giving notice thereof as provided in clause (a) of this Section.

     SECTION 11.03. PERSONS ENTITLED TO VOTE AT MEETINGS.

     To be entitled to vote at any meeting of Holders of Securities of any series, a Person shall
be (a) a Holder of one or more outstanding Securities of such series, or (b) a Person appointed by
an instrument in writing as proxy for a Holder or Holders of one or more outstanding Securities of
such series by such Holder or Holders. The only Persons who shall be entitled to be present or to
speak at any meeting of Holders of Securities of any series shall be the Persons entitled to vote
at such meeting and their counsel, any representatives of the Trustee and its counsel and any
representatives of the Company and its counsel.

50

 

     SECTION 11.04. QUORUM; ACTION.

     The Persons entitled to vote a majority in principal amount of the outstanding Securities of a
series shall constitute a quorum for a meeting of Holders of Securities of such series; PROVIDED,
HOWEVER, that if any action is to be taken at such meeting with respect to a consent or waiver
which this Indenture (or any Board Resolution or indenture supplemental hereto establishing a
series of Securities hereunder) expressly provides may be given by the Holders of more or less than
a majority in principal amount of the outstanding Securities of a series, the Persons entitled to
vote such percentage in principal amount of the outstanding Securities of such series shall
constitute a quorum. In the absence of a quorum within 30 minutes after the time appointed for any
such meeting, the meeting shall, if convened at the request of Holders of Securities of such
series, be dissolved. In any other case the meeting may be adjourned for a period of not less than
10 days as determined by the chairman of the meeting prior to the adjournment of such meeting. In
the absence of a quorum at any such adjourned meeting, such adjourned meeting may be further
adjourned for a period of not less than 10 days as determined by the chairman of the meeting prior
to the adjournment of such adjourned meeting. Notice of the reconvening of any such adjourned
meeting shall be given as provided in Section 11.02(a), except that such notice need be given only
once not less than five days prior to the date on which the meeting is scheduled to be reconvened.
Notice of the reconvening of an adjourned meeting shall state expressly the percentage, as provided
above, of the principal amount of the outstanding Securities of such series which shall constitute
a quorum.

     Except as otherwise provided in Section 6.02 or 9.02 or the last paragraph of Section 6.01 (or
in any Board Resolution or indenture supplemental hereto establishing a series of Securities
hereunder), any resolution presented to a meeting or adjourned meeting duly reconvened at which a
quorum is present as aforesaid may be adopted only by the affirmative vote of the Holders of a
majority in principal amount of the outstanding Securities of that series; PROVIDED, HOWEVER, that,
any resolution with respect to any request, demand, authorization, direction, notice, consent,
waiver or other action which this Indenture or any supplemental indenture expressly provides may be
made, given or taken by the Holders of a specified percentage in principal amount of the
outstanding Securities of a series may be adopted at a meeting or an adjourned meeting duly
reconvened and at which a quorum is present as aforesaid by the affirmative vote of the Holders of
such specified percentage in principal amount of the outstanding Securities of such series.

     Any resolution passed or decision taken at any meeting of Holders of Securities of any series
duly held in accordance with this Section shall be binding on all the Holders of Securities of such
series, whether or not such Holders were present or represented at the meeting.

     SECTION 11.05. DETERMINATION OF VOTING RIGHTS; CONDUCT AND ADJOURNMENT OF MEETINGS.

          (a) Notwithstanding any other provisions of this Indenture, the Trustee may make such
reasonable regulations as it may deem advisable for any meeting of Holders of Securities of a
series in regard to proof of the holding of Securities of such series and of the appointment of
proxies and in regard to the appointment and duties of inspectors of votes, the submission and
examination of proxies, certificates and other evidence of the right to vote, and such other
matters concerning the conduct of the meeting as it shall deem appropriate. Except as otherwise
permitted or required by any such regulations, the holding of Securities shall be

51

 

proved in the manner specified in Section 1.05 and the appointment of any proxy shall be
proved in the manner specified in Section 1.05. Such regulations may provide that written
instruments appointing proxies, regular on their face, may be presumed valid and genuine without
the proof specified in Section 1.05 or other proof.

          (b) The Trustee shall, by an instrument in writing, appoint a temporary chairman of the
meeting, unless the meeting shall have been called by the Company or by Holders of Securities as
provided in Section 11.02(b), in which case the Company or the Holders of Securities of the series
calling the meeting, as the case may be, shall in like manner appoint a temporary chairman. A
permanent chairman and a permanent secretary of the meeting shall be elected by vote of the Persons
entitled to vote at least a majority in principal amount of the outstanding Securities of such
series represented at the meeting. At any meeting each Holder of a Security of such series or
proxy shall be entitled to one vote for each $1,000 principal amount of the outstanding Securities
of such series held or represented by him; PROVIDED, HOWEVER, that no vote shall be cast or counted
at any meeting in respect of any Security challenged as not outstanding and ruled by the chairman
of the meeting to be not outstanding. The chairman of the meeting shall have no right to vote,
except as a Holder of a Security of such series or proxy.

          (c) Any meeting of Holders of Securities of any series duly called pursuant to Section 11.02
at which a quorum is present may be adjourned from time to time by Persons entitled to vote at
least a majority in principal amount of the outstanding Securities of such series represented at
the meeting; and the meeting may be held as so adjourned without further notice.

     SECTION 11.06. COUNTING VOTES AND RECORDING ACTION OF MEETINGS.

     The vote upon any resolution submitted to any meeting of Holders of Securities of any series
shall be by written ballots on which shall be subscribed the signatures of the Holders of
Securities of such series or of their representatives by proxy and the principal amounts and serial
numbers of the outstanding Securities of such series held or represented by them. The permanent
chairman of the meeting shall appoint two inspectors of votes who shall count all votes cast at the
meeting for or against any resolution and who shall make and file with the secretary of the meeting
their verified written reports in duplicate of all votes cast at the meeting. A record, at least
in duplicate, of the proceedings of each meeting of Holders of Securities of any series shall be
prepared by the secretary of the meeting and there shall be attached to said record the original
reports of the inspectors of votes on any vote by ballot taken thereat and affidavits by one or
more persons having knowledge of the facts setting forth a copy of the notice of the meeting and
showing that said notice was given as provided in Section 11.02 and, if applicable, Section 11.04.
Each copy shall be signed and verified by the affidavits of the permanent chairman and secretary of
the meeting and one such copy shall be delivered to the Company, and another to the Trustee to be
preserved by the Trustee, the latter to have attached thereto the ballots voted at the meeting.
Any record so signed and verified shall be conclusive evidence of the matters therein stated.

52

 

     SECTION 11.07. ARTICLE SUBJECT TO OTHER PROVISIONS.

     Each provision of this Article 11 (whether or not expressly so stated) is subject to any other
provision of this Indenture (or any Board Resolution or supplemental indenture establishing a
series of Securities hereunder) that provides that Securities of different series constitute a
single class.

such notice, either before or after the event, and such waiver shall be the equivalent of such
notice. Waivers of notice by Holders shall be filed with the Trustee, but such filing shall not be
a condition precedent to the validity of any action taken in reliance upon such waiver.

Company, as such, shall have any liability for any obligations of the Company under the Securities,
this Indenture or for any claim based on, in respect of, or by reason of, such obligations or their
creation. Each Holder of Securities by accepting a Security waives and releases all such
liability. The waiver and release are part of the consideration for issuance of the Securities.

     SECTION 12.14 WAIVER OF JURY TRIAL.

     EACH OF THE COMPANY AND THE TRUSTEE HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED

(Back of Note)

___% [Series __] Subordinated Note due [                    ]

     Capitalized terms used herein have the meanings assigned to them in the Indenture referred to
below unless otherwise indicated.

     1. INTEREST. The Navigators Group, Inc., a Delaware corporation (the “Company”), promises
to pay interest on the principal amount of this Note at the rate of ___% per annum from
[                    ] until maturity. The Company will pay interest [semiannually] [quarterly] on
                     and                      of each year (each an “Interest Payment Date”). Interest on the Notes
will accrue from the most recent date to which interest has been paid or duly provided for or, if
no interest has been paid or duly provided for, from the date of original issuance thereof;
PROVIDED that if there is no existing Default in the payment of interest, and if this Note is
authenticated between a record date referred to on the face hereof and the next succeeding Interest
Payment Date, interest shall accrue from such next succeeding Interest Payment Date; PROVIDED,
FURTHER, that the first Interest Payment Date shall be                                         . The Company shall pay
interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue
installments of interest (without regard to any applicable grace periods) from time to time on
demand at the same rate to the extent lawful. Interest will be computed on the basis of a 360-day
year of twelve 30-day months.

     2. METHOD OF PAYMENT. The Company will pay interest on the Notes (except defaulted interest)
to the Persons who are registered Holders of Notes at the close of business on the                      or
                     next preceding the Interest Payment Date, even if such Notes are canceled after such
record date and on or before such Interest Payment Date, except as provided in Section 2.14 of the
Indenture with respect to defaulted interest. The Notes will be payable as to principal, premium
and interest at the office or agency of the Company maintained for such purpose within or without
the State of New York; PROVIDED that payment by wire transfer of immediately available funds will
be required with respect to principal of and interest and premium on, all Global Notes and all
other Notes the Holders of which shall have provided wire transfer instructions to the Company or
the Paying Agent at least 15 days prior to the applicable payment date. Such payment shall be in
such coin or currency of the United States of America as at the time of payment is legal tender for
payment of public and private debts.

include those stated in the Indenture and in [a Supplemental Indenture] [resolutions of [the

Indenture by reference to the Trust Indenture Act of 1939, as amended (15 U.S.C. §§ 77aaa-77bbbb)

occasions, use the net proceeds of one or more offerings of its capital stock to redeem up to ___%
of the aggregate principal amount of all Notes that had been issued under the Indenture up to the
time of redemption at a redemption price of ___% of the principal amount of the Notes to be
redeemed, plus accrued and unpaid interest, to the date of redemption; PROVIDED that, after any
such redemption, the aggregate principal amount of the Notes outstanding (excluding Notes held by
the Company and its Subsidiaries) must equal at least ___% of the principal amount of the Notes

pay any taxes and fees required by law or permitted by the Indenture. The Company need not
transfer or exchange any Note selected for redemption, except for the unredeemed portion of any
Note being redeemed in part. Also, it

     9. PERSONS DEEMED OWNERS. The registered Holder of a Note may be treated as its owner for
all purposes, except as provided in the Indenture.

     10. AMENDMENT, SUPPLEMENT AND WAIVER. Subject to certain exceptions, the Indenture or the
Notes may be amended or supplemented with the consent of the Holders of a majority in principal
amount of the then outstanding Notes and other series of Securities affected (treating the Notes
and such other series as a single class), and any existing default or compliance with any provision
of the Indenture or the Notes may be waived with the consent of the Holders of a majority in
principal amount of the then outstanding Notes and other series of Securities affected (treating
the Notes and such other series as a single class). Without the consent of any Holder of a Note,

the Indenture; (iv) failure by the Company for 60 days after notice to comply with any of its other
agreements in the Indenture or the Notes; and (v) certain events of bankruptcy or insolvency with
respect to the Company. If any Event of Default occurs and is continuing, the Trustee or the
Holders of at least 25% in principal amount of the then outstanding Notes and other series of
Securities affected (treating the Notes and such other series as a single class) may declare all
the Notes to be due and payable immediately. Notwithstanding the foregoing, in the case of an
Event of Default arising from certain events of bankruptcy or insolvency with respect to the
Company, all outstanding Notes will become due and payable without further action or notice.
Holders of the Notes may not enforce the Indenture or the Notes except as provided in the
Indenture. Subject to certain limitations, Holders of a majority in principal amount of the then
outstanding Notes and other series of Securities affected (treating the Notes and such other series
as a single class) may direct the Trustee in its exercise of any trust or power. The Trustee may
withhold from Holders of the Notes notice of any continuing Default or Event of Default (except a
Default or Event of Default relating to the payment of principal or interest) if it determines that
withholding notice is in their interest. The Holders of a majority in aggregate principal amount
of the Notes and other series of Securities affected (treating the Notes and such other series as a
single class) then outstanding by notice to the Trustee may on behalf of the Holders of all of the
Notes waive any existing Default or Event of Default and its consequences under the Indenture
except a continuing Default or Event of Default in the payment of principal, interest or premium on
the Notes. The Company is required

61

 

to deliver to the Trustee annually a statement regarding compliance with the Indenture, and
the Company is required upon becoming aware of any Default or Event of Default, to deliver to the
Trustee a statement specifying such Default or Event of Default.

     12. TRUSTEE DEALINGS WITH THE COMPANY. The Trustee, in its individual or any other
capacity, may make loans to, accept deposits from, and perform services for the Company or its
Affiliates, and may otherwise deal with the Company or its Affiliates, as if it were not the
Trustee.

     13. NO RECOURSE AGAINST OTHERS. No director, officer, employee, incorporator or stockholder
of the Company shall have any liability for any obligations of the Company under the Notes or the
Indenture or for any claim based on, in respect of, or by reason of, such obligations or their
creation. Each Holder of Notes by accepting a Note waives and releases all such liability. The
waiver and release are part of the consideration for the issuance of the Notes.

     14. AUTHENTICATION. This Note shall not be valid until authenticated by the manual
signature of an authorized officer of the Trustee or an authenticating agent.

     15. ABBREVIATIONS. Customary abbreviations may be used in the name of a Holder or an

holders of Senior Debt. Each Holder of a Note, by the Holder’s acceptance thereof authorizes and
directs the Trustee on the Holder’s behalf to take such action as may be necessary or appropriate
to effectuate the subordination as provided in Article 10 of the Indenture, and appoints the
Trustee to act as the Holder’s attorney-in-fact for any and all such purposes.
