THE SECURITIES

Section 2.1 Issuable in Series.

     The aggregate principal amount of Securities that may be authenticated and delivered under
this Indenture is unlimited. The Securities may be issued in one or more Series. All Securities of
a Series shall be identical except as may be set forth in a Board Resolution, a supplemental
indenture or an Officers’ Certificate detailing the adoption of the terms thereof pursuant to the
authority granted under a Board Resolution. In the case of Securities of a Series to be issued from
time to time, the Board Resolution, Officers’ Certificate or supplemental indenture may provide for
the method by which specified terms (such as interest rate, maturity date, record date or date from
which interest shall accrue) are to be determined. Securities may differ between Series in respect
of any matters, provided that all Series of Securities shall be equally and ratably entitled to the
benefits of the Indenture [INCLUDE THIS LANGUAGE FOR SUBORDINATED SECURITIES... but all Securities
issued hereunder shall be subordinate and junior in right of payment, to the extent and in the
manner set forth in Article XII, to all Senior Indebtedness of the Company.]

     At or prior to the issuance of any Securities within a Series, the following shall be

the Securities of the Series will be issued;

     2.2.3 any limit upon the aggregate principal amount of the Securities of the Series which may

the Series pursuant to Section 2.7, 2.8, 2.11, 3.6 or 9.6);

2.2.4 the date or dates on which the principal of the Securities of the Series is payable;

shall bear interest, if any, the date or dates from which such interest, if any, shall accrue, the
date or dates on which such interest, if any, shall commence and be payable and any regular record
date for the interest payable on any interest payment date;

     2.2.6 the place or places where the principal of and interest, if any, on the Securities of
the Series shall be payable, or the method of such payment, if by wire transfer, mail or other

terms and conditions upon which the Securities of the Series may be redeemed, in whole or in part,
at the option of the Company;

     2.2.8 the obligation, if any, of the Company to redeem or purchase the Securities of the
Series pursuant to any sinking fund or analogous provisions or at the option of a Holder thereof
and the period or periods within which, the price or prices at which and the terms and conditions
upon which Securities of the Series shall be redeemed or purchased, in whole or in part, pursuant
to such obligation;

Series will be repurchased by the Company at the option of the Holders thereof and other detailed
terms and provisions of such repurchase obligations;

     2.2.10 if other than denominations of $2,000 and any integral multiple thereof, the
denominations in which the Securities of the Series shall be issuable;

     2.2.11 the forms of the Securities of the Series in bearer or fully registered form (and, if
in fully registered form, whether the Securities will be issuable as Global Securities);

     2.2.12 if other than the principal amount thereof, the portion of the principal amount of the
Securities of the Series that shall be payable upon declaration of acceleration of the maturity

     2.2.14 the designation of the currency, currencies or currency units in which payment of the

     2.2.16 the manner in which the amounts of payment of principal of or interest, if any, on the

     2.2.17 the provisions, if any, relating to any security provided for the Securities of the
Series;

8

 

     2.2.18 if the holders of Securities of the Series may convert or exchange the Securities into
or for securities of the Issuer or of other entities or other property, the period or periods
within which, the rate or rates at which and the terms and conditions upon which Securities of the
Series may be converted or exchanged, in whole or in part;

     2.2.19 any addition to or change in the Events of Default which applies to any Securities of
the Series and any change in the right of the Trustee or the requisite Holders of such Securities
to declare the principal amount thereof due and payable pursuant to Section 6.2;

     2.2.20 any addition to or change in the covenants set forth in Articles IV or V which applies
to Securities of the Series;

     2.2.21 any other terms of the Securities of the Series (which terms shall not be inconsistent
with the provisions of this Indenture, except as permitted by Section 9.1, but which may modify or
delete any provision of this Indenture insofar as it applies to such Series); and

     2.2.22 any depositories, interest rate calculation agents, exchange rate calculation agents or
other agents with respect to Securities of such Series if other than those appointed herein.

All Securities of any one Series need not be issued at the same time and may be issued from time to
time, consistent with the terms of this Indenture, if so provided by or pursuant to the Board
Resolution, supplemental indenture or Officers’ Certificate referred to above, and the authorized
principal amount of any Series may not be increased to provide for issuances of additional
Securities of such Series, unless otherwise provided in such Board Resolution, supplemental
indenture or Officers’ Certificate.

Section 2.3 Execution and Authentication.

     Two Officers 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 the
Security is authenticated, the Security shall nevertheless be valid.

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

     The Trustee shall at any time, and from time to time, authenticate Securities for original
issue in the principal amount provided in the Board Resolution, supplemental indenture hereto or
Officers’ Certificate, upon receipt by the Trustee of a Company Order. Such Company Order may
authorize authentication and delivery pursuant to oral or electronic instructions from the Company
or its duly authorized agent or agents, which oral instructions shall be promptly confirmed in
writing. Each Security
shall be dated the date of its authentication unless otherwise provided by a Board Resolution,
a supplemental indenture hereto or an Officers’ Certificate.

     The aggregate principal amount of Securities of any Series outstanding at any time may not
exceed any limit upon the maximum principal amount for such Series set forth in the Board
Resolution, supplemental indenture hereto or Officers’ Certificate delivered pursuant to Section
2.2, except as provided in Section 2.8.

     Prior to the issuance of Securities of any Series, the Trustee shall have received and
(subject to Section 7.2) shall be fully protected in relying on:

9

 

	 	(a)	 	the Board Resolution, supplemental indenture hereto or Officers’ Certificate
establishing the form of the Securities of that Series or of Securities within that
Series and the terms of the Securities of that Series or of Securities within that
Series,
	 
	 	(b)	 	an Officers’ Certificate complying with Section 10.4, and
	 
	 	(c)	 	an Opinion of Counsel complying with Section 10.4.

     The Trustee shall have the right to decline to authenticate and deliver any Securities of such
Series: (a) if the Trustee, being advised by counsel, determines that such action may not lawfully
be taken; or (b) if the Trustee in good faith by its board of directors or trustees, executive
committee or a trust committee of directors and/or vice-presidents shall determine that such action
would expose the Trustee to personal liability to Holders of any then outstanding Series of
Securities.

     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 the Company or an
Affiliate.

Section 2.4 Registrar and Paying Agent.

     The Company shall maintain, with respect to each Series of Securities, at the place or places
specified with respect to such Series pursuant to Section 2.2, an office or agency where Securities
of such Series may be presented or surrendered for payment (“Paying Agent”), where Securities of
such Series may be surrendered for registration of transfer or exchange (“Registrar”) and where
notices and demands to or upon the Company in respect of the Securities of such Series and this
Indenture may be served (“Service Agent”). The Registrar shall keep a register with respect to each
Series of Securities and to their transfer and exchange. The Company will give prompt written
notice to the Trustee of the name and address, and any change in the name or address, of each
Registrar, Paying Agent or Service Agent. If at any time the Company shall fail to maintain any
such required Registrar, Paying Agent or Service Agent or shall fail to furnish the Trustee with
the name and address thereof, such presentations, surrenders, notices and demands may be made or
served at the Corporate Trust Office of the Trustee, and the Company hereby appoints the Trustee as
its agent to receive all such presentations, surrenders, notices and demands.

     The Company may also from time to time designate one or more co-registrars, additional paying
agents or additional service agents 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
obligations to maintain a Registrar, Paying Agent and Service Agent in each place so specified
pursuant to Section 2.2 for Securities of any Series for such purposes. The Company will give
prompt written notice to the Trustee of any such designation or rescission and of any change in the
name or address of any such co-registrar, additional paying agent or additional service agent. The
term “Registrar” includes any co-registrar; the term “Paying Agent” includes any additional paying
agent; and the term “Service Agent” includes any additional service agent.

     The Company hereby appoints the Trustee the initial Registrar, Paying Agent and Service Agent
for each Series unless another Registrar, Paying Agent or Service Agent, as the case may be, is
appointed prior to the time Securities of that Series are first issued.

10

 

Section 2.5 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 Securityholders of any Series of
Securities, or the Trustee, all money held by the Paying Agent for the payment of principal of or
interest on the Series of Securities, and will notify the Trustee of any default by the Company in
making any such payment. 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 Securityholders of any Series of Securities all money held by it as Paying
Agent.

Section 2.6 Securityholder 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 Securityholders of each Series of Securities and
shall otherwise comply with TIA Section 312(a). If the Trustee is not the Registrar, the Company
shall furnish to the Trustee at least ten 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 Securityholders of each Series of Securities.

Section 2.7 Transfer and Exchange.

     Where Securities of a Series are presented to the Registrar or a co-registrar with a request
to register a transfer or to exchange them for an equal principal amount of Securities of the same
Series, the Registrar shall register the transfer or make the exchange if its requirements for such
transactions are met. To permit registrations of transfers and exchanges, the Trustee shall
authenticate Securities at the Registrar’s request. No service charge shall be made for any
registration of transfer or exchange (except as otherwise expressly permitted herein), but the
Company may require payment of a sum sufficient to cover any transfer tax or similar governmental
charge payable in connection therewith (other than any such transfer tax or similar governmental
charge payable upon exchanges pursuant to Sections 2.11, 3.6 or 9.6).

     Neither the Company nor the Registrar shall be required (a) to issue, register the transfer
of, or exchange Securities of any Series for the period beginning at the opening of business
fifteen days immediately preceding the mailing of a notice of redemption of Securities of that
Series selected for redemption and ending at the close of business on the day of such mailing, or
(b) to register the transfer of or exchange Securities of any Series selected, called or being
called for redemption as a whole or the portion being redeemed of any such Securities selected,
called or being called for redemption in part.

Section 2.8 Mutilated, Destroyed, Lost and Stolen Securities.

     If any mutilated Security is surrendered to the Trustee, the Company shall execute and the
Trustee shall authenticate and deliver in exchange therefor a new Security of the same Series and
of like tenor and principal amount and bearing a number not contemporaneously outstanding.

     If there shall be delivered to the Company and the Trustee (i) evidence to their satisfaction
of the destruction, loss or theft of any Security and (ii) such security or indemnity as may be
required by them to save each of them and any agent of either of them harmless, then, in the
absence of notice to the Company or the Trustee that such Security has been acquired by a bona fide
purchaser, the Company shall execute

11

 

and upon its request the Trustee shall authenticate and make
available for delivery, in lieu of any such destroyed, lost or stolen Security, a new Security of
the same Series and of like tenor and principal amount and bearing a number not contemporaneously
outstanding.

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

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

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

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

Section 2.9 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 on a Global Security effected by the Trustee in accordance with the provisions hereof and
those described in this Section as not outstanding.

     If a Security is replaced pursuant to Section 2.8, it ceases to be outstanding until the
Trustee receives proof satisfactory to it that the replaced Security is held by a bona fide
purchaser.

     If the Paying Agent (other than the Company, a Subsidiary or an Affiliate of any thereof)
holds on the Maturity of Securities of a Series money sufficient to pay such Securities payable on
that date, then on and after that date such Securities of the Series cease to be outstanding and
interest on them ceases to accrue.

     A Security does not cease to be outstanding because the Company or an Affiliate holds the
Security.

     In determining whether the Holders of the requisite principal amount of outstanding Securities
have given any request, demand, authorization, direction, notice, consent or waiver hereunder, the
principal amount of a Discount Security that shall be deemed to be outstanding for such purposes
shall be the amount of the principal thereof that would be due and payable as of the date of such
determination upon a declaration of acceleration of the Maturity thereof pursuant to Section 6.2.

Section 2.10 Treasury Securities.

     In determining whether the Holders of the required principal amount of Securities of a Series
have concurred in any request, demand, authorization, direction, notice, consent or waiver
Securities of a Series owned by the Company or an Affiliate shall be disregarded, except that for
the purposes of determining whether the Trustee shall be protected in relying on any such request,
demand, authorization,

12

 

direction, notice, consent or waiver only Securities of a Series that the
Trustee knows are so owned shall be so disregarded.

Section 2.11 Temporary Securities.

     Until definitive Securities are ready for delivery, the Company may prepare and the Trustee
shall authenticate temporary Securities upon a Company Order. Temporary Securities shall be
substantially in the form of definitive Securities but may have variations that the Company
considers appropriate for temporary Securities. Without unreasonable delay, the Company shall
prepare and the Trustee upon request shall authenticate definitive Securities of the same Series
and date of maturity in exchange for temporary Securities. Until so exchanged, temporary securities
shall have the same rights under this Indenture as the definitive Securities.

Section 2.12 Cancellation.

     The Company at any time may deliver Securities to the Trustee for cancellation. The Registrar
and the Paying Agent shall forward to the Trustee any Securities surrendered to them for
registration of transfer, exchange or payment. The Trustee shall cancel all Securities surrendered
for transfer, exchange, payment, replacement or cancellation and shall destroy such canceled
Securities (subject to the record retention requirement of the Exchange Act) and deliver a
certificate of such destruction to the Company, unless the Company otherwise directs. The Company
may not issue new Securities to replace Securities that it has paid or delivered to the Trustee for
cancellation.

Section 2.13 Defaulted Interest.

     If the Company defaults in a payment of interest on a Series of Securities, it shall pay the
defaulted interest, plus, to the extent permitted by law, any interest payable on the defaulted
interest, to the persons who are Securityholders of the Series on a subsequent special record date.
The Company shall fix the record date and payment date. At least 30 days before the record date,
the Company shall mail to the Trustee and to each Securityholder of the Series a notice that states
the record date, the payment date and the amount of interest to be paid. The Company may pay
defaulted interest in any other lawful manner.

Section 2.14 Global Securities.

     2.14.1 Terms of Securities. A Board Resolution, a supplemental indenture hereto or an
Officers’ Certificate shall establish whether the Securities of a Series shall be issued in whole
or in part in the form of one or more Global Securities and the Depository for such Global Security
or Securities.

     2.14.2 Transfer and Exchange. Notwithstanding any provisions to the contrary contained
in Section 2.7 of the Indenture and in addition thereto, any Global Security shall be exchangeable
pursuant to Section 2.7 of the Indenture for Securities registered in the names of Holders other
than the Depository for such Security or its nominee only if (i) such Depository notifies the
Company that it is unwilling or unable to continue as Depository for such Global Security or if at
any time such Depository ceases to be a clearing agency registered under the Exchange Act, and, in
either case, the Company fails to appoint a successor Depository within 90 days of such event, (ii)
the Company executes and delivers to the Trustee an Officers’ Certificate to the effect that such
Global Security shall be so exchangeable or (iii) an Event of Default with respect to the
Securities represented by such Global Security shall have happened and be continuing. Any Global
Security that is exchangeable pursuant to the preceding sentence shall be exchangeable for
Securities registered in such names as the Depository shall direct in writing in an aggregate
principal amount equal to the principal amount of the Global Security with like tenor and terms.

13

 

Except as provided in this Section 2.14.2, a Global Security may not be transferred except as a
whole by the Depository with respect to such Global Security to a nominee of such Depository, by a
nominee of such Depository to such Depository or another nominee of such Depository or by the
Depository or any such nominee to a successor Depository or a nominee of such a successor
Depository.

     2.14.3 Legend. Unless otherwise provided pursuant to Section 2.2, any Global Security
issued hereunder shall bear a legend in substantially the following form:

     “This Security is a Global Security within the meaning of the Indenture hereinafter referred
to and is registered in the name of the Depository or a nominee of the Depository. This Security is
exchangeable for Securities registered in the name of a person other than the Depository or its
nominee only in the limited circumstances described in the Indenture, and may not be transferred
except as a whole by the Depository to a nominee of the Depository, by a nominee of the Depository
to the Depository or another nominee of the Depository or by the Depository or any such nominee to
a successor Depository or a nominee of such a successor Depository.”

     2.14.4 Acts of Holders. The Depository, as a Holder, may appoint agents and otherwise
authorize participants to give or take any request, demand, authorization, direction, notice,
consent, waiver or other action which a Holder is entitled to give or take under the Indenture.

     2.14.5 Payments. Notwithstanding the other provisions of this Indenture, unless
otherwise specified as contemplated by Section 2.2, payment of the principal of, premium, if any,
and interest, if any, on any Global Security shall be made to the Holder thereof.

     2.14.6 Consents, Declaration and Directions. Except as provided in Section 2.14.5, the
Company, the Trustee and any Agent shall treat a person as the Holder of such principal amount of
outstanding Securities of such Series represented by a Global Security as shall be specified in a
written statement of the Depositary with respect to such Global Security, for purposes of obtaining
any consents, declarations, waivers or directions required to be given by the Holders pursuant to
this Indenture.

Section 2.15 CUSIP Numbers.

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

ARTICLE III.

REDEMPTION

Section 3.1 Notice to Trustee.

     The Company may, with respect to any Series of Securities, reserve the right to redeem and pay
the Series of Securities or may covenant to redeem and pay the Series of Securities or any part
thereof prior to the Stated Maturity thereof at such time and on such terms as provided for in such
Securities. If a Series of Securities is redeemable and the Company wants or is obligated to redeem
prior to the Stated Maturity thereof all or part of the Series of Securities pursuant to the terms
of such Securities, it shall notify the Trustee of the redemption date and the principal amount of
Series of Securities to be redeemed.

14

 

The Company shall give the notice at least 45 days before the
redemption date (or such shorter notice as may be acceptable to the Trustee).

Section 3.2 Selection of Securities to be Redeemed.

     Unless otherwise indicated for a particular Series by a Board Resolution, a supplemental
indenture or an Officers’ Certificate, if less than all the Securities of a Series are to be
redeemed, the Trustee shall select the Securities of the Series to be redeemed in any manner that
the Trustee deems fair and appropriate. The Trustee shall make the selection from Securities of the
Series outstanding not previously called for redemption. The Trustee may select for redemption
portions of the principal of Securities of the Series that have denominations larger than $2,000.
Securities of the Series and portions
of them it selects shall be in amounts of $2,000 or whole multiples of $2,000 or, with respect
to Securities of any Series issuable in other denominations pursuant to Section 2.2.10, the minimum
principal denomination for each Series and integral multiples thereof. Provisions of this Indenture
that apply to Securities of a Series called for redemption also apply to portions of Securities of
that Series called for redemption.

Section 3.3 Notice of Redemption.

     Unless otherwise indicated for a particular Series by Board Resolution, a supplemental
indenture hereto or an Officers’ Certificate, at least 30 days but not more than 60 days before a
redemption date, the Company shall mail a notice of redemption by first-class mail to each Holder
whose Securities are to be redeemed and if any Bearer Securities are outstanding, publish on one
occasion a notice in an Authorized Newspaper.

     The notice shall identify the Securities of the Series to be redeemed and shall state:

	 	(a)	 	the redemption date;
	 
	 	(b)	 	the redemption price;
	 
	 	(c)	 	the name and address of the Paying Agent;
	 
	 	(d)	 	that Securities of the Series called for redemption must be surrendered to the
Paying Agent to collect the redemption price;
	 
	 	(e)	 	that interest on Securities of the Series called for redemption ceases to
accrue on and after the redemption date; and
	 
	 	(f)	 	any other information as may be required by the terms of the particular Series
or the Securities of a Series being redeemed.

     At the Company’s request, the Trustee shall give the notice of redemption in the Company’s
name and at its expense.

Section 3.4 Effect of Notice of Redemption.

     Once notice of redemption is mailed or published as provided in Section 3.3, Securities of a
Series called for redemption become due and payable on the redemption date and at the redemption
price. A notice of redemption may not be conditional. Upon surrender to the Paying Agent, such
Securities shall be paid at the redemption price plus accrued interest to the redemption date.

15

 

Section 3.5 Deposit of Redemption Price.

     On or before the redemption date, the Company shall deposit with the Paying Agent money
sufficient to pay the redemption price of and accrued interest, if any, on all Securities to be

Officers’ Certificate, it is provided that such Series shall not have the benefit of said Event of
Default:

	 	(a)	 	default in the payment of any interest on any Security of that Series when it
becomes due and payable, and continuance of such default for a period of 30 days
(unless the entire amount of such payment is deposited by the Company with the Trustee

	 	(b)	 	default in the payment of the principal of any Security of that Series at its
Maturity; or

in this Indenture (other than a covenant or warranty that has been included in this
Indenture solely for the benefit of Series of Securities other than that Series), which
default continues uncured for a period of 90 days after there has been given, by
registered or certified mail, to the Company by the Trustee or to the Company and the
Trustee by the Holders of at least 25% in principal amount of the outstanding
Securities of that Series a written notice specifying such default or breach and
requiring it to be remedied and stating that such notice is a “Notice of Default”

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

Section 6.2 Acceleration of Maturity; Rescission and Annulment.

     If an Event of Default with respect to Securities of any Series at the time outstanding occurs
and is continuing (other than an Event of Default referred to in Section 6.1(e) or (f) ) then in
every such case the Trustee or the Holders of not less than 25% in principal amount of the
outstanding Securities of that Series may declare the principal amount (or, if any Securities of
that Series are Discount Securities, such portion of the principal amount as may be specified in
the terms of such Securities) of and accrued and unpaid interest, if any, on all of the Securities
of that Series to be due and payable immediately, by a notice in writing to the Company (and to the
Trustee if given by Holders), and upon any such declaration such principal amount (or specified
amount) and accrued and unpaid interest, if any, shall become immediately due and payable. If an
Event of Default specified in Section 6.1(e) or (f) shall occur, the principal amount (or specified
amount) of and accrued and unpaid interest, if any, on all outstanding Securities shall ipso facto
become and be immediately due and payable without any declaration or other act on the part of the
Trustee or any Holder.

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

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

	 	(i)	 	all overdue interest, if any, on all Securities of that Series,
	 
	 	(ii)	 	the principal of any Securities of that Series which have
become due otherwise than by such declaration of acceleration and interest
thereon at the rate or rates prescribed therefor in such Securities,
	 
	 	(iii)	 	to the extent that payment of such interest is lawful,
interest upon any overdue principal and overdue interest at the rate or rates
prescribed therefor in such Securities, and
	 
	 	(iv)	 	all sums paid or advanced by the Trustee hereunder and the
reasonable compensation, expenses, disbursements and advances of the Trustee,
its agents and counsel; and

19

 

	 	(b)	 	all Events of Default with respect to Securities of that Series, other than the
non-payment of the principal of Securities of that Series which have become due solely
by such declaration of acceleration, have been cured or waived as provided in Section
6.13.

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

Section 6.3 Collection of Indebtedness and Suits for Enforcement by Trustee.

     The Company covenants that if

	 	(a)	 	default is made in the payment of any interest on any Security when such
interest becomes due and payable and such default continues for a period of 30 days, or
	 
	 	(b)	 	default is made in the payment of principal of any Security at the Maturity
thereof, or
	 
	 	(c)	 	default is made in the deposit of any sinking fund payment when and as due by
the terms of a Security, then, the Company will, upon demand of the Trustee, pay to it,
for the benefit of the Holders of such Securities, the whole amount then due and
payable on such Securities for principal and interest and, to the extent that payment
of such interest shall be legally enforceable, interest on any overdue principal or any
overdue interest, at the rate or rates prescribed therefor in such Securities, and, in
addition thereto, such further amount as shall be sufficient to cover the costs and
expenses of collection, including the reasonable compensation, expenses, disbursements
and advances of the Trustee, its agents and counsel.

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

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

Section 6.4 Trustee May File Proofs of Claim.

     In case of the pendency of any receivership, insolvency, liquidation, bankruptcy,
reorganization, arrangement, adjustment, composition or other judicial proceeding relative to the
Company or any other obligor upon the Securities or the property of the Company or of such other
obligor or their creditors, the Trustee (irrespective of whether the principal of the Securities
shall then be due and payable as therein expressed or by declaration or otherwise and irrespective
of whether the Trustee shall have made any demand on the Company for the payment of overdue
principal or interest) shall be entitled and empowered, by intervention in such proceeding or
otherwise,

	 	(a)	 	to file and prove a claim for the whole amount of principal and interest owing
and unpaid in respect of the Securities and to file such other papers or documents as
may be

20

 

	 	 	 	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 of the Holders allowed in such judicial
proceeding, and
	 
	 	(b)	 	to collect and receive any moneys or other property payable or deliverable on
any such claims and to distribute the same, and any custodian, receiver, assignee,
trustee, liquidator, sequestrator or other similar official in any such judicial
proceeding is hereby authorized by each Holder to make such payments to the Trustee
and, in the event that the Trustee shall consent to the making of such payments
directly to the Holders, to pay to the Trustee any amount due it for the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents and
counsel, and any other amounts due the Trustee under Section 7.7.

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

Section 6.5 Trustee May Enforce Claims Without Possession of Securities.

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

Section 6.6 Application of Money Collected.

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

     First: To the payment of all amounts due the Trustee under Section 7.7; and

     Second: To the payment of the amounts then due and unpaid for principal of and interest on the
Securities in respect of which or for the benefit of which such money has been collected, ratably,
without preference or priority of any kind, according to the amounts due and payable on such
Securities for principal and interest, respectively; and

     Third: To the Company.

Section 6.7 Limitation on Suits.

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

21

 

	 	(a)	 	such Holder has previously given written notice to the Trustee of a continuing
Event of Default with respect to the Securities of that Series;
	 
	 	(b)	 	the Holders of not less than 25% in principal amount of the outstanding
Securities of that Series shall have made written request to the Trustee to institute
proceedings in respect of such Event of Default in its own name as Trustee hereunder;
	 
	 	(c)	 	such Holder or Holders have offered to the Trustee reasonable indemnity against
the costs, expenses and liabilities to be incurred in compliance with such request;
	 
	 	(d)	 	the Trustee for 60 days after its receipt of such notice, request and offer of
indemnity has failed to institute any such proceeding; and
	 
	 	(e)	 	no direction inconsistent with such written request has been given to the
Trustee during such 60-day period by the Holders of a majority in principal amount of
the outstanding Securities of that Series; it being understood and intended that no one
or more of such Holders shall have any right in any manner whatever by virtue of, or by
availing of, any provision of this Indenture to affect, disturb or prejudice the rights
of any other of such Holders, or to obtain or to seek to obtain priority or preference
over any other of such Holders or to enforce any right under this Indenture, except in
the manner herein provided and for the equal and ratable benefit of all such Holders.

Section 6.8 Unconditional Right of Holders to Receive Principal and Interest.

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

Section 6.9 Restoration of Rights and Remedies.

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

Section 6.10 Rights and Remedies Cumulative.

     Except as otherwise provided with respect to the replacement or payment of mutilated,
destroyed, lost or stolen Securities in Section 2.8, no right or remedy herein conferred upon or
reserved to the Trustee or to the Holders is intended to be exclusive of any other right or remedy,
and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to
every other right and remedy given hereunder or now or hereafter existing at law or in equity or
otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not
prevent the concurrent assertion or employment of any other appropriate right or remedy.

22

 

Section 6.11 Delay or Omission Not Waiver.

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

Section 6.12 Control by Holders.

     The Holders of a majority in principal amount of the outstanding Securities of any Series
shall have the right to direct the time, method and place of conducting any proceeding for any
remedy available to the Trustee, or exercising any trust or power conferred on the Trustee, with
respect to the Securities of such Series, provided that

	 	(a)	 	such direction shall not be in conflict with any rule of law or with this
Indenture,
	 
	 	(b)	 	the Trustee may take any other action deemed proper by the Trustee which is not
inconsistent with such direction, and
	 
	 	(c)	 	subject to the provisions of Section 6.1, the Trustee shall have the right to
decline to follow any such direction if the Trustee in good faith shall, by a
Responsible Officer of the Trustee, determine that the proceeding so directed would
involve the Trustee in personal liability.

Section 6.13 Waiver of Past Defaults.

     Subject to Section 6.2, the Holders of not less than a majority in principal amount of the
outstanding Securities of any Series may on behalf of the Holders of all the Securities of such
Series waive any past Default hereunder with respect to such Series and its consequences, except a
Default in the payment of the principal of or interest on any Security of such Series (provided,
however, that the Holders of a majority in principal amount of the outstanding Securities of any
Series may rescind an acceleration and its consequences, including any related payment default that
resulted from such acceleration). Upon any such waiver, such Default shall cease to exist, and any
Event of Default arising therefrom shall be deemed to have been cured, for every purpose of this
Indenture; but no such waiver shall extend to any subsequent or other Default or impair any right
consequent thereon.

Section 6.14 Undertaking for Costs.

     All parties to this Indenture agree, and each Holder of any Security by his acceptance thereof
shall be deemed to have agreed, that any court may in its discretion require, in any suit for the
enforcement of any right or remedy under this Indenture, or in any suit against the Trustee for any
action taken, suffered or omitted by it as Trustee, the filing by any party litigant in such suit
of an undertaking to pay the costs of such suit, and that such court may in its discretion assess
reasonable costs, including reasonable attorneys’ fees, against any party litigant in such suit,
having due regard to the merits and good faith of the claims or defenses made by such party
litigant; but the provisions of this Section shall not apply to any suit instituted by the Company,
to any suit instituted by the Trustee, to any suit instituted by any Holder, or group of Holders,
holding in the aggregate more than 10% in principal amount of the outstanding Securities of any
Series, or to any suit instituted by any Holder for the enforcement of the payment of the principal
of or interest on any Security on or after the Stated Maturity or Stated Maturities expressed in
such Security (or, in the case of redemption, on the redemption date).

ARTICLE VII.

TRUSTEE

Section 7.1 Duties of Trustee.

	 	(a)	 	If an Event of Default has occurred and is continuing, the Trustee shall
exercise the rights and powers vested in it by this Indenture and use the same degree
of care and skill in their exercise as a prudent man would exercise or use under the
circumstances in the conduct of his own affairs.
	 
	 	(b)	 	Except during the continuance of an Event of Default:

	 	(i)	 	The Trustee need perform only those duties that are
specifically set forth in this Indenture and no others.
	 
	 	(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 Officers’ Certificates or Opinions of Counsel
furnished to the Trustee and conforming to the requirements of this Indenture;
however, in the case of any such Officers’ Certificates or Opinions of Counsel
which by any provisions hereof are specifically required to be furnished to the
Trustee, the Trustee shall examine such Officers’ Certificates and Opinions of
Counsel to determine whether or not they conform to the requirements of this
Indenture.

	 	(c)	 	The Trustee may not be relieved from liability 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 proved that the Trustee
was negligent in ascertaining the pertinent facts.

taken, suffered or omitted to be taken by it with respect to Securities of any
Series in good faith in accordance with the direction of the Holders of a
majority in principal amount of the outstanding Securities of such Series
relating to the time, method and place of conducting any proceeding for any
remedy available to the Trustee, or exercising any trust or power conferred
upon the Trustee, under this Indenture with respect to the Securities of such
Series.

unless it receives indemnity satisfactory to it against any loss, liability or expense.
	 
	 	(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.

24

 

	 	(g)	 	No provision of this Indenture shall require the Trustee to risk its own funds
or otherwise incur any financial liability in the performance of any of its duties, or
in the exercise of any of its rights or powers, if it shall have reasonable grounds for
believing that repayment of such funds or adequate indemnity against such risk is not
reasonably assured to it.
	 
	 	(h)	 	The Paying Agent, the Registrar and any authenticating agent shall be entitled
to the protections and immunities as are set forth in paragraphs (a), (b) and (c) of
this Section with respect to the Trustee.

Section 7.2 Rights of Trustee.

	 	(a)	 	The Trustee may rely on and shall be protected in acting or refraining from
acting upon any document believed by it to be genuine and to have been signed or
presented by the proper 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. 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.
	 
	 	(c)	 	The Trustee may act through agents and shall not be responsible for the
misconduct or negligence of any agent appointed with due care. No Depository shall be
deemed an agent of the Trustee and the Trustee shall not be responsible for any act or
omission by any Depository.
	 
	 	(d)	 	The Trustee shall not be liable for any action it takes or omits to take in
good faith which it believes to be authorized or within its rights or powers.
	 
	 	(e)	 	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 in respect
of any action taken, suffered or omitted by it hereunder in good faith and in reliance
thereon.
	 
	 	(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
of Securities unless such Holders shall have offered to the Trustee reasonable security
or indemnity against the costs, expenses and liabilities which might be incurred by it
in compliance with such request or direction.

Section 7.3 Individual Rights of Trustee.

     The Trustee in its individual or any other capacity may become the owner or pledgee of

subject to Sections 7.10 and 7.11.

Section 7.4 Trustee’s Disclaimer.

     The Trustee 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,

each Securityholder of the Securities of that Series and, if any Bearer Securities are outstanding,
publish on one occasion in an Authorized Newspaper, notice of a Default or Event of Default within
90 days after it occurs or, if later, after a Responsible Officer of the Trustee has knowledge of
such Default or Event of Default. Except in the case of a Default or Event of Default in payment of
principal of or interest on any Security of any Series, the Trustee may withhold the notice if and
so long as its corporate trust committee or a committee of its Responsible Officers in good faith
determines that withholding the notice is in the interests of Securityholders of that Series.

Section 7.6 Reports by Trustee to Holders.

     Within 60 days after May 15 in each year, the Trustee shall transmit by mail to all
Securityholders, as their names and addresses appear on the register kept by the Registrar and, if
any Bearer Securities are outstanding, publish in an Authorized Newspaper, a brief report dated as
of such May 15, in accordance with, and to the extent required under, TIA Section 313.

     A copy of each report at the time of its mailing to Securityholders of any Series shall be

Company shall promptly notify the Trustee when Securities of any Series are listed on any stock
exchange.

of an express trust. The Company shall reimburse the Trustee upon request for all reasonable
out-of-pocket expenses incurred by it. Such expenses shall include the reasonable compensation and
expenses of the Trustee’s agents and counsel.

     The Company shall indemnify the Trustee (including the cost of defending itself) against any
loss, liability or expense incurred by it except as set forth in the next paragraph in the
performance of its duties under this Indenture as Trustee or Agent. The Trustee shall notify the
Company promptly of any claim for which it may seek indemnity. 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. This
indemnification shall apply to officers, directors, employees, shareholders and agents of the
Trustee.

     The Company need not reimburse any expense or indemnify against any loss or liability incurred
by the Trustee or by any officer, director, employee, shareholder or agent of the Trustee through
negligence or bad faith.

     To secure the Company’s payment obligations in this Section, the Trustee shall have a lien
prior to the Securities of any Series on all money or property held or collected by the Trustee,
except that held in trust to pay principal and interest on particular Securities of that Series.

     When the Trustee incurs expenses or renders services after an Event of Default specified in
Section 6.1(e) or (f) occurs, the expenses and the compensation for the services are intended to
constitute expenses of administration under any Bankruptcy Law.

Section 7.8 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 the Securities of one or more Series by so notifying
the Company. The Holders of a majority in principal amount of the Securities of any Series may
remove the Trustee with respect to that Series by so notifying the Trustee and the Company. The
Company may remove the Trustee with respect to Securities of one or more Series if:

	 	(a)	 	the Trustee fails to comply with Section 7.10;
	 
	 	(b)	 	the Trustee is adjudged a bankrupt or an 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 may appoint a successor Trustee to replace the successor Trustee appointed by the
Company.

     If a successor Trustee with respect to the Securities of any one or more Series 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 Securities of the applicable
Series may petition any court of competent jurisdiction for the appointment of a successor Trustee.

     If the Trustee with respect to the Securities of any one or more Series fails to comply with
Section 7.10, any Securityholder of the applicable Series 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. Immediately after that, the retiring Trustee shall transfer all
property held by it as Trustee to the successor Trustee subject to the lien provided for in Section
7.7, 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 with respect to each Series of
Securities for which it is acting as Trustee under this Indenture. A successor Trustee shall mail a
notice of its succession to each Securityholder of each such Series and, if any Bearer Securities
are outstanding, publish such notice on one occasion in an Authorized Newspaper. Notwithstanding
replacement of the Trustee pursuant to this Section 7.8, the Company’s obligations under Section
7.7 hereof shall continue for the benefit of the retiring trustee with respect to expenses and
liabilities incurred by it prior to such replacement.

Section 7.9 Successor Trustee by Merger, etc.

     If the Trustee consolidates with, 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.

27

 

Section 7.10 Eligibility; Disqualification.

$25,000,000 as set forth in its most recent published annual report of condition. The Trustee shall
comply with TIA Section 310(b).

Section 7.11 Preferential Collection of Claims Against Company.

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

certification thereof delivered to the Trustee, are then in excess of the amount
thereof which then would have been required to be deposited for the purpose for which
such U.S. Government Obligations or Foreign Government Obligations or money were
deposited or received. This provision shall not authorize the sale by the Trustee of
any U.S. Government Obligations or Foreign Government Obligations held under this

same), except as to:

	 	(a)	 	the rights of Holders of Securities of such Series to receive, from the trust
funds described in subparagraph (d) hereof, (i) payment of the principal of and each

sufficient, in the opinion of a nationally recognized firm of independent public
accountants expressed in a written certification thereof delivered to the Trustee, to

analogous payments) of and interest, if any, on all the Securities of such Series on
the dates such installments of interest or principal are due;

income tax law, in either case to the effect that, and based thereon such Opinion of
Counsel shall confirm that, the Holders of the Securities of such Series will not
recognize income, gain or loss for Federal income tax purposes as a result of such
deposit, defeasance and discharge and will be subject to Federal income tax on the
same amount and in the same manner and at the same times as would have been the case
if such deposit, defeasance and discharge had not occurred;
	 
	 	(h)	 	the Company shall have delivered to the Trustee an Officers’ Certificate
stating that the deposit was not made by the Company with the intent of preferring the
Holders of the Securities of such Series over any other creditors of the company or

in a supplemental indenture hereto for a particular Series of Securities or a Board Resolution or
an Officers’ Certificate delivered pursuant to Section 2.2.21 (and the failure to comply with any
such covenants shall not constitute a Default or Event of Default under Section 6.1) and the

Event of Default hereunder, with respect to the Securities of such Series, provided that the
following conditions shall have been satisfied:

irrevocably deposited (except as provided in Section 8.2(c) ) with the Trustee as trust

benefit of the Holders of such Securities (i) in the case of Securities of such Series
denominated in Dollars, cash in Dollars (or such other money or currencies as shall
then be legal tender in the United States) and/or U.S. Government Obligations, or (ii)

	 	(d)	 	the Company shall have delivered to the Trustee an Opinion of Counsel
confirming that Holders of the Securities of such Series will not recognize income,
gain or loss for federal income tax purposes as a result of such deposit and 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 deposit and defeasance had not
occurred;

31

 

	 	(e)	 	the Company shall have delivered to the Trustee an Officers’ Certificate
stating the deposit was not made by the Company with the intent of preferring the

Securityholders entitled to the money must look to the Company for payment as general creditors
unless an applicable abandoned property law designates another person.

Section 8.6 Reinstatement.

     If the Trustee or Paying Agent is unable to apply any money or U.S. Government Obligations in
accordance with Sections 8.1, 8.3 or 8.4, as the case may be, by reason of any legal proceeding or
by reason of any order or judgment of any court or governmental authority enjoining, restraining or
otherwise prohibiting such application, the Company’s obligations under this Indenture and the
Securities shall be revived and reinstated as though no deposit had occurred pursuant to Section
8.1, 8.3 or 8.4, as the case may be, until such time as the Trustee or Paying Agent is permitted to
apply all such money or U.S. Government Obligations in accordance with Section 8.1, 8.3 or 8.4, as
the case may be; provided, however, that if the Company makes any payment of principal of, premium,
if any, or interest on any Securities because of 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 or U.S. Government Obligations held by the Trustee or Paying Agent.

ARTICLE IX.

qualification of this Indenture under the TIA.
	 
	 	(h)	 	to conform the text of the indentures to any provision of the Description of

securities and to release guarantors in accordance with the terms of the indenture.
	 
	 	(j)	 	to add additional obligors under the indenture and the securities.

Section 9.2 With Consent of Holders.

     The Company and the Trustee may enter into a supplemental indenture with the written consent
of the Holders of at least a majority in principal amount of the outstanding Securities of each
Series affected by such supplemental indenture (including consents obtained in connection with a
tender offer or exchange offer for the Securities of such Series), for the purpose of adding any
provisions to or changing in any manner or eliminating any of the provisions of this Indenture or
of any supplemental indenture or of modifying in any manner the rights of the Securityholders of
each such Series. Except as provided in Section 6.13, the Holders of at least a majority in
principal amount of the outstanding Securities of each Series affected by such waiver by notice to
the Trustee (including consents obtained in connection with a tender offer or exchange offer for
the Securities of such Series) may waive compliance by the Company with any provision of this
Indenture or the Securities with respect to such Series.

     It shall not be necessary for the consent of the Holders of Securities under this Section 9.2
to approve the particular form of any proposed supplemental indenture or waiver, but it shall be
sufficient if
such consent approves the substance thereof. After a supplemental indenture or waiver under
this Section becomes effective, the Company shall mail to the Holders of Securities affected
thereby and, if any Bearer Securities affected thereby are outstanding, publish on one occasion in
an Authorized Newspaper, a notice briefly describing the supplemental indenture or waiver. Any
failure by the Company to mail or publish such notice, or any defect therein, shall not, however,
in any way impair or affect the validity of any such supplemental indenture or waiver.

Section 9.3 Limitations.

     Without the consent of each Securityholder affected, an amendment or waiver may not:

	 	(a)	 	change the amount of Securities whose Holders must consent to an amendment,
supplement or waiver;
	 
	 	(b)	 	reduce the rate of or extend the time for payment of interest (including
default interest) on any Security;
	 
	 	(c)	 	reduce the principal or change the Stated Maturity of any Security or reduce
the amount of, or postpone the date fixed for, the payment of any sinking fund or
analogous obligation;

33

 

	 	(d)	 	reduce the principal amount of Discount Securities payable upon acceleration of
the maturity thereof;
	 
	 	(e)	 	waive a Default or Event of Default in the payment of the principal of or
interest, if any, on any Security (except a rescission of acceleration of the
Securities of any Series by the Holders of at least a majority in principal amount of
the outstanding Securities of such Series and a waiver of the payment default that
resulted from such acceleration);
	 
	 	(f)	 	make the principal of or interest, if any, on any Security payable in any
currency other than that stated in the Security;
	 
	 	(g)	 	make any change in Sections 6.8, 6.13, 9.3 (this sentence), 10.15 or 10.16; or
	 
	 	(h)	 	waive a redemption payment with respect to any Security or change any of the
provisions with respect to the redemption of any Securities.

Section 9.4 Compliance with Trust Indenture Act.

     Every amendment to this Indenture or the Securities of one or more Series shall be set forth
in a supplemental indenture hereto that complies with the TIA as then in effect.

Section 9.5 Revocation and Effect of Consents.

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

     Any amendment or waiver once effective shall bind every Securityholder of each Series affected
by such amendment or waiver unless it is of the type described in any of clauses (a) through (g) of
Section 9.3. In that case, the amendment or waiver shall bind each Holder of a Security who has
consented to it and every subsequent Holder of a Security or portion of a Security that evidences
the same debt as the consenting Holder’s Security.

Section 9.6 Notation on or Exchange of Securities.

     The Trustee may place an appropriate notation about an amendment or waiver on any Security of
any Series thereafter authenticated. The Company in exchange for Securities of that Series may
issue and the Trustee shall authenticate upon request new Securities of that Series that reflect
the amendment or waiver.

Section 9.7 Trustee Protected.

     In executing, or accepting the additional trusts created by, any supplemental indenture
permitted by this Article or the modifications thereby of the trusts created by this Indenture, the
Trustee shall be entitled to receive, and (subject to Section 7.1) shall be fully protected in
relying upon, an Opinion of Counsel stating that the execution of such supplemental indenture is
authorized or permitted by this Indenture. The Trustee shall sign all supplemental indentures,
except that the Trustee need not sign any supplemental indenture that adversely affects its rights.

Section 10.15 Securities in a Foreign Currency or in ECU.

     Unless otherwise specified in a Board Resolution, a supplemental indenture hereto or an
Officers’ Certificate delivered pursuant to Section 2.2 of this Indenture with respect to a
particular Series of Securities, whenever for purposes of this Indenture any action may be taken by
the Holders of a specified percentage in aggregate principal amount of Securities of all Series or
all Series affected by a particular action at the time outstanding and, at such time, there are
outstanding Securities of any Series which are denominated in a coin or currency other than Dollars
(including ECUs), then the principal amount of Securities of such Series which shall be deemed to
be outstanding for the purpose of taking such action
shall be that amount of Dollars that could be obtained for such amount at the Market Exchange
Rate at such time. For purposes of this Section 10.15, “Market Exchange Rate” shall mean the noon
Dollar buying rate in New York City for cable transfers of that currency as published by the
Federal Reserve Bank of New York; provided, however, in the case of ECUs, Market Exchange Rate
shall mean the rate of exchange determined by the Commission of the European Union (or any
successor thereto) as published in the Official Journal of the European Union (such publication or
any successor publication, the “Journal”). If such Market Exchange Rate is not available for any
reason with respect to such

37

 

currency, the Trustee shall use, in its sole discretion and without
liability on its part, such quotation of the Federal Reserve Bank of New York or, in the case of
ECUs, the rate of exchange as published in the Journal, as of the most recent available date, or
quotations or, in the case of ECUs, rates of exchange from one or more major banks in The City of
New York or in the country of issue of the currency in question or, in the case of ECUs, in
Luxembourg or such other quotations or, in the case of ECUs, rates of exchange as the Trustee, upon
consultation with the Company, shall deem appropriate. The provisions of this paragraph shall apply
in determining the equivalent principal amount in respect of Securities of a Series denominated in
currency other than Dollars in connection with any action taken by Holders of Securities pursuant
to the terms of this Indenture.

     All decisions and determinations of the Trustee regarding the Market Exchange Rate or any
alternative determination provided for in the preceding paragraph shall be in its sole discretion
and shall, in the absence of manifest error, be conclusive to the extent permitted by law for all
purposes and irrevocably binding upon the Company and all Holders.

Section 10.16 Judgment Currency.

     The Company agrees, to the fullest extent that it may effectively do so under applicable law,
that (a) if for the purpose of obtaining judgment in any court it is necessary to convert the sum
due in respect of the principal of or interest or other amount on the Securities of any Series (the
“Required Currency”) into a currency in which a judgment will be rendered (the “Judgment
Currency”), the rate of exchange used shall be the rate at which in accordance with normal banking
procedures the Trustee could purchase in The City of New York the Required Currency with the
Judgment Currency on the day on which final unappealable judgment is entered, unless such day is
not a New York Banking Day, then, the rate of exchange used shall be the rate at which in
accordance with normal banking procedures the Trustee could purchase in The City of New York the
Required Currency with the Judgment Currency on the New York Banking Day preceding the day on which
final unappealable judgment is entered and (b) its obligations under this Indenture to make
payments in the Required Currency (i) shall not be discharged or satisfied by any tender, any
recovery pursuant to any judgment (whether or not entered in accordance with Subsection (a)), in
any currency other than the Required Currency, except to the extent that such tender or recovery
shall result in the actual receipt, by the payee, of the full amount of the Required Currency
expressed to be payable in respect of such payments, (ii) shall be enforceable as an alternative or
additional cause of action for the purpose of recovering in the Required Currency the amount, if
any, by which such actual receipt shall fall short of the full amount of the Required Currency so
expressed to be payable, and (iii) shall not be affected by judgment being obtained for any other
sum due under this Indenture. For purposes of the foregoing, “New York Banking Day” means any day
except a Saturday, Sunday or a legal holiday in The City of New York on which banking institutions
are authorized or required by law, regulation or executive order to close.

ARTICLE XI.

SINKING FUNDS

Section 11.1 Applicability of Article.

     The provisions of this Article shall be applicable to any sinking fund for the retirement of
the Securities of a Series, except as otherwise permitted or required by any form of Security of
such Series issued pursuant to this Indenture.

     The minimum amount of any sinking fund payment provided for by the terms of the Securities of
any Series is herein referred to as a “mandatory sinking fund payment” and any other amount
provided for by the terms of Securities of such Series is herein referred to as an “optional
sinking fund payment.” If

38

 

provided for by the terms of Securities of any Series, the cash amount of
any sinking fund payment may be subject to reduction as provided in Section 11.2. Each sinking fund
payment shall be applied to the redemption of Securities of any Series as provided for by the terms
of the Securities of such Series.

Section 11.2 Satisfaction of Sinking Fund Payments with Securities.

     The Company may, in satisfaction of all or any part of any sinking fund payment with respect
to the Securities of any Series to be made pursuant to the terms of such Securities (1) deliver
outstanding Securities of such Series to which such sinking fund payment is applicable (other than
any of such Securities previously called for mandatory sinking fund redemption) and (2) apply as
credit Securities of such Series to which such sinking fund payment is applicable and which have
been redeemed either at the election of the Company pursuant to the terms of such Series of
Securities (except pursuant to any mandatory sinking fund) or through the application of permitted
optional sinking fund payments or other optional redemptions pursuant to the terms of such
Securities, provided that such Securities have not been previously so credited. Such Securities
shall be received by the Trustee, together with an Officers’ Certificate with respect thereto, not
later than 15 days prior to the date on which the Trustee begins the process of selecting
Securities for redemption, and shall be credited for such purpose by the Trustee at the price
specified in such Securities for redemption through operation of the sinking fund and the amount of
such sinking fund payment shall be reduced accordingly. If as a result of the delivery or credit of
Securities in lieu of cash payments pursuant to this Section 11.2, the principal amount of
Securities of such Series to be redeemed in order to exhaust the aforesaid cash payment shall be
less than $100,000, the Trustee need not call Securities of such Series for redemption, except upon
receipt of a Company Order that such action be taken, and such cash payment shall be held by the
Trustee or a Paying Agent and applied to the next succeeding sinking fund payment, provided,
however, that the Trustee or such Paying Agent shall from time to time upon receipt of a Company
Order pay over and deliver to the Company any cash payment so being held by the Trustee or such
Paying Agent upon delivery by the Company to the Trustee of Securities of that Series purchased by
the Company having an unpaid principal amount equal to the cash payment required to be released to
the Company.

Section 11.3 Redemption of Securities for Sinking Fund.

     Not less than 45 days (unless otherwise indicated in the Board Resolution, supplemental
indenture hereto or Officers’ Certificate in respect of a particular Series of Securities) prior to
each sinking fund payment date for any Series of Securities, the Company will deliver to the
Trustee an Officers’ Certificate specifying the amount of the next ensuing mandatory sinking fund
payment for that Series pursuant to the terms of that Series, the portion thereof, if any, which is
to be satisfied by payment
of cash and the portion thereof, if any, which is to be satisfied by delivering and crediting
of Securities of that Series pursuant to Section 11.2, and the optional amount, if any, to be added
in cash to the next ensuing mandatory sinking fund payment, and the Company shall thereupon be
obligated to pay the amount therein specified. Not less than 30 days (unless otherwise indicated in
the Board Resolution, Officers’ Certificate or supplemental indenture in respect of a particular
Series of Securities) before each such sinking fund payment date the Trustee shall select the
Securities to be redeemed upon such sinking fund payment date in the manner specified in Section
3.2 and cause notice of the redemption thereof to be given in the name of and at the expense of the
Company in the manner provided in Section 3.3. Such notice having been duly given, the redemption
of such Securities shall be made upon the terms and in the manner stated in Sections 3.4, 3.5 and
3.6.

[INCLUDE ARTICLE XII FOR SUBORDINATED SECURITIES...

ARTICLE XII.

SUBORDINATION OF SECURITIES

39

 

Section 12.1 Agreement of Subordination.

     The Company covenants and agrees, and each Holder of Securities issued hereunder by his
acceptance thereof likewise covenants and agrees, that all Securities shall be issued subject to
the provisions of this Article XII; and each Person holding any Security, whether upon original
issue or upon transfer, assignment or exchange thereof, accepts and agrees to be bound by such
provisions.

     The payment of the principal of, premium, if any, and interest on all Securities (including,
but not limited to, the redemption price with respect to the Securities called for redemption in
accordance with Article 3 as provided in the Indenture) issued hereunder shall, to the extent and
in the manner hereinafter set forth, be subordinated and subject in right of payment to the prior
payment in full of all Senior Indebtedness, whether outstanding at the date of this Indenture or
thereafter incurred (except that holders of the notes may receive and retain (i) Permitted Junior
Securities and (ii) payments made pursuant to Article VIII hereof).

     No provision of this Article XII shall prevent the occurrence of any default or Event of
Default hereunder.

Section 12.2 Payments to Holders.

     No payment shall be made with respect to the principal of, or premium, if any, or interest on
the Securities (including, but not limited to, the redemption price with respect to the Securities
to be called for redemption in accordance with Article III as provided in the Indenture), except
payments and distributions made by the Trustee as permitted by the first or second paragraph of
Section 12.5, if:

	 	(i)	 	a default in the payment of principal, premium, interest, rent
or other obligations due on any Senior Indebtedness occurs and is continuing
(or, in the case of Senior Indebtedness for which there is a period of grace,
in the event of such a default that continues beyond the period of grace, if
any, specified in the instrument or lease evidencing such Senior Indebtedness),
unless and until such default shall have been cured or waived or shall have
ceased to exist; or
	 
	 	(ii)	 	a default, other than a payment default, on a Designated Senior
Indebtedness occurs and is continuing that then permits holders of such
Designated Senior Indebtedness to accelerate its maturity and the Trustee
receives a notice of the default (a “Payment Blockage Notice”) from a
Representative or the Company.

     If the Trustee receives any Payment Blockage Notice pursuant to clause (ii) above, no
subsequent Payment Blockage Notice shall be effective for purposes of this Section unless and until
(a) at least 365 days shall have elapsed since the initial effectiveness of the immediately prior
Payment Blockage Notice, and (b) all scheduled payments of principal, premium, if any, and interest
on the Securities that have come due have been paid in full in cash. No nonpayment default 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.

     The Company may and shall resume payments on and distributions in respect of the Securities
upon the earlier of:

	 	(1)	 	the date upon which the default is cured or waived or ceases to
exist, or

40

 

	 	(2)	 	in the case of a default referred to in clause (ii) above, 179
days pass after notice is received if the maturity of such Designated Senior
Indebtedness has not been accelerated, unless this Article XII otherwise
prohibits the payment or distribution at the time of such payment or
distribution.

     Upon any payment by the Company, or distribution of assets of the Company of any kind or
character, whether in cash, property or securities, to creditors upon any dissolution or winding-up
or liquidation or reorganization of the Company, whether voluntary or involuntary or in bankruptcy,
insolvency, receivership or other proceedings, all amounts due or to become due upon all Senior
Indebtedness shall first be paid in full in cash or other payment satisfactory to the holders of
such Senior Indebtedness, or payment thereof in accordance with its terms provided for in cash or
other payment satisfactory to the holders of such Senior Indebtedness, before any payment is made
on account of the principal of, premium, if any, or interest on the Securities (except payments
made pursuant to Article VI from monies deposited with the Trustee pursuant thereto prior to
commencement of proceedings for such dissolution, winding-up, liquidation or reorganization); and
upon any such dissolution or winding-up or liquidation or reorganization of the Company or
bankruptcy, insolvency, receivership or other proceeding, any payment by the Company, or
distribution of assets of the Company of any kind or character, whether in cash, property or
securities, to which the Holders of the Securities or the Trustee would be entitled, except for the
provision of this Article XII, shall (except as aforesaid) be paid by the Company or by any
receiver, trustee in bankruptcy, liquidating trustee, agent or other Person making such payment or
distribution, or by the Holders of the Securities or by the Trustee under this Indenture if
received by them or it, directly to the holders of Senior Indebtedness (pro rata to such holders on
the basis of the respective amounts of Senior Indebtedness held by such holders, or as otherwise
required by law or a court order) or their representative or representatives, or to the trustee or
trustees under any indenture pursuant to which any instruments evidencing any Senior Indebtedness
may have been issued, as their respective interests may appear, to the extent necessary to pay all
Senior Indebtedness in full, in cash or other payment satisfactory to the holders of such Senior
Indebtedness, after giving effect to any concurrent payment or distribution to or for the holders
of Senior Indebtedness, before any payment or distribution or provision therefor is made to the
Holders of the Securities or to the Trustee.

     For purposes of this Article XII, the words, “cash, property or securities” shall not be
deemed to include shares of stock of the Company as reorganized or readjusted, or securities of the
Company or any other corporation provided for by a plan of reorganization or readjustment, the
payment of which is
subordinated at least to the extent provided in this Article XII with respect to the
Securities to the payment of all Senior Indebtedness which may at the time be outstanding; provided
that (i) the Senior Indebtedness is assumed by the new corporation, if any, resulting from any
reorganization or readjustment, and (ii) the rights of the holders of Senior Indebtedness (other
than leases which are not assumed by the Company or the new corporation, as the case may be) are
not, without the consent of such holders, altered by such reorganization or readjustment. The
consolidation of the Company with, or the merger of the Company into, another corporation or the
liquidation or dissolution of the Company following the conveyance or transfer of its property as
an entirety, or substantially as an entirety, to another corporation upon the terms and conditions
provided for in Article V shall not be deemed a dissolution, winding-up, liquidation or
reorganization for the purposes of this Section 12.2 if such other corporation shall, as a part of
such consolidation, merger, conveyance or transfer, comply with the conditions stated in Article V.

     In the event of the acceleration of the Securities because of an Event of Default, no payment
or distribution shall be made to the Trustee or any Holder of Securities in respect of the
principal of, premium, if any, or interest on the Securities (including, but not limited to, the
redemption price with respect to the Securities called for redemption in accordance with Article 3
as provided in the Indenture), except payments and distributions made by the Trustee as permitted
by the first or second paragraph of

41

 

Section 12.5, until all Senior Indebtedness has been paid in
full in cash or other payment satisfactory to the holders of Senior Indebtedness or such
acceleration is rescinded in accordance with the terms of this Indenture. If payment of the
Securities is accelerated because of an Event of Default, the Company shall promptly notify holders
of Senior Indebtedness of the acceleration at the address set forth in the notice from the Agent
(or successor agent) to the Trustee as being the address to which the Trustee should send its
notice pursuant to this Section 12.2, unless there are no payment obligations of the Company
thereunder and all obligations thereunder to extend credit have been terminated or expired.

     In the event that, notwithstanding the foregoing provisions, any payment or distribution of
assets of the Company of any kind or character, whether in cash, property or securities (including,
without limitation, by way of setoff or otherwise), prohibited by the foregoing, shall be received
by the Trustee or the Holders of the Securities before all Senior Indebtedness is paid in full in
cash or other payment satisfactory to the holders of such Senior Indebtedness, or provision is made
for such payment thereof in accordance with its terms in cash or other payment satisfactory to the
holders of such Senior Indebtedness, such payment or distribution shall be held in trust for the
benefit of and shall be paid over or delivered to the holders of Senior Indebtedness or their
representative or representatives, or to the trustee or trustees under any indenture pursuant to
which any instruments evidencing any Senior Indebtedness may have been issued, as their respective
interests may appear, as calculated by the Company, for application to the payment of all Senior
Indebtedness remaining unpaid to the extent necessary to pay all Senior Indebtedness in full in
cash or other payment satisfactory to the holders of such Senior Indebtedness, after giving effect
to any concurrent payment or distribution to or for the holders of such Senior Indebtedness.

     Nothing in this Section 12.2 shall apply to claims of, or payments to, the Trustee under or
pursuant to Section 7.7. This Section 12.2 shall be subject to the further provisions of Section
12.5.

Section 12.3 Subrogation of Securities.

     Subject to the payment in full of all Senior Indebtedness, the rights of the Holders of the
Securities shall be subrogated to the extent of the payments or distributions made to the holders
of such Senior Indebtedness pursuant to the provisions of this Article XII (equally and ratably
with the holders of
all indebtedness of the Company which by its express terms is subordinated to other
indebtedness of the Company to substantially the same extent as the Securities are subordinated and
is entitled to like rights of subrogation) to the rights of the holders of Senior Indebtedness to
receive payments or distributions of cash, property or securities of the Company applicable to the
Senior Indebtedness until the principal, premium, if any, and interest on the Securities shall be
paid in full; and, for the purposes of such subrogation, no payments or distributions to the
holders of the Senior Indebtedness of any cash, property or securities to which the Holders of the
Securities or the Trustee would be entitled except for the provisions of this Article XII, and no
payment over pursuant to the provisions of this Article XII, to or for the benefit of the holders
of Senior Indebtedness by Holders of the Securities or the Trustee, shall, as between the Company,
its creditors other than holders of Senior Indebtedness, and the Holders of the Securities, be
deemed to be a payment by the Company to or on account of the Senior Indebtedness; and no payments
or distributions of cash, property or securities to or for the benefit of the Holders of the
Securities pursuant to the subrogation provisions of this Article XII, which would otherwise have
been paid to the holders of Senior Indebtedness shall be deemed to be a payment by the Company to
or for the account of the Securities. It is understood that the provisions of this Article XII are
and are intended solely for the purposes of defining the relative rights of the Holders of the
Securities, on the one hand, and the holders of the Senior Indebtedness, on the other hand.

     Nothing contained in this Article XII or elsewhere in this Indenture or in the Securities is
intended to or shall impair, as among the Company, its creditors other than the holders of Senior

42

 

Indebtedness, and the Holders of the Securities, the obligation of the Company, which is absolute
and unconditional, to pay to the Holders of the Securities the principal of (and premium, if any)
and interest on the Securities as and when the same shall become due and payable in accordance with
their terms, or is intended to or shall affect the relative rights of the Holders of the Securities
and creditors of the Company other than the holders of the Senior Indebtedness, nor shall anything
herein or therein prevent the Trustee or the Holder of any Security from exercising all remedies
otherwise permitted by applicable law upon default under this Indenture, subject to the rights, if
any, under this Article XII of the holders of Senior Indebtedness in respect of cash, property or
securities of the Company received upon the exercise of any such remedy.

     Upon any payment or distribution of assets of the Company referred to in this Article XII, the
Trustee, subject to the provisions of Section 7.1, and the Holders of the Securities shall be
entitled to rely upon any order or decree made by any court of competent jurisdiction in which such
bankruptcy, dissolution, winding-up, liquidation or reorganization proceedings are pending, or a
certificate of the receiver, trustee in bankruptcy, liquidating trustee, agent or other person
making such payment or distribution, delivered to the Trustee or to the Holders of the Securities,
for the purpose of ascertaining the persons entitled to participate in such distribution, the
holders of the Senior Indebtedness and other indebtedness of the Company, the amount thereof or
payable thereon and all other facts pertinent thereto or to this Article XII.

Section 12.4 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 XII 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 proof of
claim or proof of debt in the form required in any proceeding referred to in Section 6.3 hereof at
least 30 days before the expiration of the time to file such claim, the holders of any Senior
Indebtedness or their representatives are hereby authorized to file an appropriate claim for and on
behalf of the Holders of the Securities.

Section 12.5 Notice to Trustee.

     The Company shall give prompt written notice in the form of an Officers’ Certificate to a
Responsible Officer of the Trustee and to any paying agent of any fact known to the Company which
would prohibit the making of any payment of monies to or by the Trustee or any paying agent in
respect of the Securities pursuant to the provisions of this Article XII. Notwithstanding the
provisions of this Article XII or any other provision of this Indenture, the Trustee shall not be
charged with knowledge of the existence of any facts which would prohibit the making of any payment
of monies to or by the Trustee in respect of the Securities pursuant to the provisions of this
Article XII, unless and until a Responsible Officer of the Trustee shall have received written
notice thereof at the Corporate Trust Office from the Company (in the form of an Officers’
Certificate) or a Representative or a holder or holders of Senior Indebtedness or from any trustee
thereof; and before the receipt of any such written notice, the Trustee, subject to the provisions
of Section 7.1, shall be entitled in all respects to assume that no such facts exist; provided that
if on a date not fewer than two Business Days prior to the date upon which by the terms hereof any
such monies may become payable for any purpose (including, without limitation, the payment of the
principal of, or premium, if any, or interest on any Security) the Trustee shall not have received,
with respect to such monies, the notice provided for in this Section 12.5, then, anything herein
contained to the contrary notwithstanding, the Trustee shall have full power and authority to
receive such monies and to apply the same to the purpose for which they were received, and shall
not be affected by any notice to the contrary which may be received by it on or after such prior
date.

43

 

     Notwithstanding anything in this Article XII to the contrary, nothing shall prevent any
payment by the Trustee to the Holders of monies deposited with it pursuant to Section 8.1, and any
such payment shall not be subject to the provisions of Section 12.1 or 12.2.

     The Trustee, subject to the provisions of Section 7.1, shall be entitled to rely on the
delivery to it of a written notice by a Representative or a person representing himself to be a
holder of Senior Indebtedness (or a trustee on behalf of such holder) to establish that such notice
has been given by a Representative or a holder of Senior Indebtedness or a trustee on behalf of any
such holder or holders. In the event that the Trustee determines in good faith that further
evidence is required with respect to the right of any person as a holder of Senior Indebtedness to
participate in any payment or distribution pursuant to this Article XII, the Trustee may request
such person to furnish evidence to the reasonable satisfaction of the Trustee as to the amount of
Senior Indebtedness held by such person, the extent to which such person is entitled to participate
in such payment or distribution and any other facts pertinent to the rights of such person under
this Article XII, 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 12.6 Trustee’s Relation to Senior Indebtedness.

     The Trustee in its individual capacity shall be entitled to all the rights set forth in this
Article XII in respect of any Senior Indebtedness at any time held by it, to the same extent as any
other holder of Senior Indebtedness, and nothing in Section 7.11 or elsewhere in this Indenture
shall deprive the Trustee of any of its rights as such holder.

     With respect to the holders of Senior Indebtedness, the Trustee undertakes to perform or to
observe only such of its covenants and obligations as are specifically set forth in this Article
XII, and no
implied covenants or obligations with respect to the holders of Senior Indebtedness 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 Indebtedness and, subject to the provisions of Section 7.1, the
Trustee shall not be liable to any holder of Senior Indebtedness if it shall pay over or deliver to
Holders of Securities, the Company or any other person money or assets to which any holder of
Senior Indebtedness shall be entitled by virtue of this Article XII or otherwise.

Section 12.7 No Impairment of Subordination.

     No right of any present or future holder of any Senior Indebtedness to enforce subordination
as herein provided shall at any time in any way be prejudiced or impaired by any act or failure to
act on the part of the Company or by any act or failure to act, in good faith, by any such holder,
or by any noncompliance by the Company with the terms, provisions and covenants of this Indenture,
regardless of any knowledge thereof which any such holder may have or otherwise be charged with.

Section 12.8 Article Applicable to Paying Agents.

     If at any time any Paying Agent other than the Trustee shall have been appointed by the
Company and be then acting hereunder, the term “Trustee” as used in this Article shall (unless the
context otherwise requires) be construed as extending to and including such Paying Agent within its
meaning as fully for all intents and purposes as if such Paying Agent were named in this Article in
addition to or in place of the Trustee; provided, however, that the first paragraph of Section 12.5
shall not apply to the Company or any Affiliate of the Company if it or such Affiliate acts as
Paying Agent.

44

 

Section 12.9 Senior Indebtedness Entitled to Rely.

     The holders of Senior Indebtedness (including, without limitation, Designated Senior
Indebtedness) shall have the right to rely upon this Article XII, and no amendment or modification
of the provisions contained herein shall diminish the rights of such holders unless such holders
shall have agreed in writing thereto.

payments, collectively, constitute my Severance Pay. This Severance Pay will be subject to all
applicable federal, state and local taxes and related employment deductions.

     2.2. Vacation Time Cashout. I will receive a gross payment of $17,091.97 for my unused but

     2.3. Final Wages. I have my final gross wages of $3,365.38, exclusive of any Bonus
Compensation (as described in section 2.3.1. of this Agreement) less all applicable federal, state
and local taxes and related employment deductions. This constitutes my final accrued and unpaid
wages from the Company. I agree that I am not entitled to any additional wages (other than the
Bonus Compensation as described in section 2.3.1 of this Agreement, as approved), from the Company.

          2.3.1. Bonus Compensation. Subject to the terms of my Fiscal Year 2006 Chief Operating
Officer Compensation Plan, executed by me on February 1, 2006, and as approved by the Compensation
Committee of the Board of Directors of the Company, I agree that I will receive a gross amount of
$563,405 from the Company. This amount constitutes the entire amount of my Bonus Compensation to
which I am entitled from the Company. This amount shall be subject to all appropriate federal,
state, and local taxes and other customary and proper payroll deductions. I understand that the
Bonus Compensation, as approved by the Compensation Committee of the Board of Directors of the
Company, will be paid to me to me no later than forty-eight (48) hours after final approval by the
Compensation Committee. I agree that I am not entitled to any additional Bonus Compensation from
the Company. I further agree that the Bonus Compensation described in section 2.3.1. of this
Agreement is not being paid in consideration of my providing the Release to the Company contained
in section 3 of this Agreement.

Incentive Plan, as amended, and the 2006 Stock Incentive Plan, and the related non-qualified stock
option agreements for each stock option grant (collectively “Stock Option Plans”). I understand
and agree that the provisions of the Stock Option Plan are controlling over my rights to obtain
stock options associated with my employment at the Company. I agree that I am not entitled to any
additional options, or any acceleration of the granting of new options, or the acceleration of the
vesting of existing options from the Company under the Company’s Stock Option Plans.

     2.5. 60 Day Notice Payment. I understand that my resignation is occurring during a reduction
of force by the Company. Accordingly, I have received a gross amount of $26,923.12 equal to 60
days wages. This amount shall be subject to all appropriate federal, state, and local taxes and
other customary and proper payroll deductions.

          2.5.1. Benefit Reimbursements. The Company agrees to pay me the gross amount of $3,051.81.
This amount shall be subject to all appropriate federal, state, and local taxes and other customary
and proper payroll deductions. The net amount is equal to the cost of continuing my employment
benefits for the next 60 days. I will receive this amount regardless of whether I elect to
continue my employment benefits pursuant to COBRA following the termination of my employment with
the Company.

     2.6. 401k, SERP, & Deferred Compensation. I will be eligible for a distribution of my vested
401k account, Supplemental Executive Retirement Plan No. 2 (SERP No. 2) account, and Deferred

     2.7. Eligibility for Continuation Benefits. As to Company-provided medical, dental or vision
plans in which I participate, I will be entitled to buy continued health plan coverage under the
normal COBRA health care continuation rules. Details regarding this coverage will be provided to
me under separate cover.

     2.8. Indemnification. The Company agrees that it will indemnify me in my role as an officer
of the Company in accordance with the Seventh Article of the Certificate of Incorporation, as
amended, of the Company which provides that employees and officers of the Company shall be
indemnified to the fullest extent provided by the General Corporation Law of the State of Delaware
(“DGCL”), provided my actions are within the scope contemplated by the DGCL. The Company
acknowledges that such indemnification includes actions, suits, claims or proceedings related to my
role as the named Responsible Managing Officer on behalf of the Company, including but not limited
to Continental Residential, Inc., D.R. Horton San Diego Holding Company, Inc. and Western Pacific
Housing Management, Inc., under State of California Contractors Licenses, provided my actions are
within the scope contemplated by the DGCL. I agree to meet with and cooperate, to the fullest
extent of the law, with the Company and its counsel, in any action for which the Company provides
me indemnification.

     2.9. Payments by the Company

          2.9.1. I agree that the Severance Pay described in subsection 2.1, is a benefit that the
Company is not required to pay me under its normal policies and procedures or under the Employment
Agreement. The benefits described in sections 2.2, 2.3, 2.5, and 2.5.1 of this Agreement have been
paid to me and I have received them, on my last date of employment, which is October 20, 2006. I
understand that I will receive the Bonus Compensation described in section 2.3.1 as approved by the
Compensation Committee of the Board of Directors, no later than forty-eight (48) hours after
approval by the Compensation Committee.

          2.9.2. I understand and agree that my Severance Pay under subsection 2.1 will be paid or made
available to me only if (1) I have signed and returned this Release to the Company within 45 days;
(2) I have not revoked the Agreement, which I understand I may do within seven days after I sign
it; and (3), I have returned all Company property as required by section 4.3 of this Agreement.
The Company will not pay me the Severance Pay described in section 2.1 until after the expiration
of the seven-day revocation period (or if I have revoked this Agreement, then the Company will not
pay me the severance pay at all) and after it has certified that I have, in fact, returned all
Company property as required by this Agreement.

     2.10. No Other Payments. I agree that other than the consideration and other payments listed
in this Agreement, and with the exception of those payments mandated by law, I am not entitled to
any other consideration, cash, payment, salary, wage, commission, severance, distribution, fringe
benefit (excluding my 401k plan contributions, SERP No. 2, and Deferred Compensation Plan), COBRA
benefit, insurance, vacation/personal pay and/or bonus compensation, under any employment policy,
this Agreement or any other prior oral and/or written agreement. Except for the obligations and
promises set forth in this Agreement, I agree and understand that this Agreement releases the
Released Parties from each and every obligation,

OWBPA Severance Agreement

Page 3 of 10

 

 

monetary or otherwise, owed to me now and in the future.

3. Complete Release

     3.1. In General. I irrevocably and unconditionally release all the Claims described in
subsection 3.2 that I may now have against the Released Parties listed in subsection 3.4, except
that I am not releasing any Claim that relates to: (i) my right to enforce this Release or (ii) any
rights or claims under the Age Discrimination in Employment Act or any other law that may arise
after I sign this Release.

     3.2. Claims Released. Subject only to the exceptions just noted, I am releasing all known and
unknown claims, promises, causes of action, or similar rights of any type that I presently may have
(“Claims”) with respect to any Released Party listed in subsection 3.4. I understand that the
Claims I am releasing might arise under many different laws (including statutes, regulations, other
administrative guidance, and common law doctrines), such as the following:

Antidiscrimination statutes, such as the Age Discrimination in Employment Act and Executive
Order 11,141, which prohibit age discrimination in employment; Title VII of the Civil Rights
Act of 1964, Sections 1981 and 1983 of the Civil Rights Act of 1866, and Executive Order
11,246, which prohibit discrimination based on race, color, national origin, religion, or
sex; the Equal Pay Act, which prohibits paying men and women unequal pay for equal work; the
Americans with Disabilities Act and Sections 503 and 504 of the Rehabilitation Act of 1973,
which prohibit discrimination based on disability; and any other federal, state, or local
laws prohibiting employment discrimination, such as the California Fair Employment and
Housing Act, which prohibits discrimination based on race, color, national origin, ancestry,
physical or mental disability, medical condition, marital status, sex, age, or sexual
orientation;

Federal employment statutes, such as the WARN Act, which requires that advance notice be
given of certain workforce reductions; the Employee Retirement Income Security Act of 1974,
which, among other things, protects employee benefits; the Fair Labor Standards Act of 1938,
which regulates wage and hour matters; the Family and Medical Leave Act of 1993, which
requires employers to provide leaves of absence under certain circumstances; and any other
federal laws relating to employment, such as veterans’ reemployment rights laws.

Other laws, such as federal, state, or local laws providing workers’ compensation benefits,
restricting an employer’s right to terminate employees, or otherwise regulating employment;
any federal, state, or local law enforcing express or implied employment contracts or
requiring an employer to deal with employees fairly or in good faith; any other federal,
state, or local laws providing recourse for alleged wrongful discharge, tort, physical or
personal injury, emotional distress, fraud, negligent misrepresentation, defamation, and
similar or related claims, such as California Labor Code sections 200 et

OWBPA Severance Agreement

Page 4 of 10

 

 

seq. relating to salary, commissions, compensation, benefits and other matters, and any
applicable California Industrial Welfare Commission order.

Examples of released Claims include, but are not limited to: (i) Claims that in any way
relate to my employment with the Company, or the termination of that employment, such as
Claims for compensation, bonuses, commissions, lost wages, or unused accrued vacation or
sick pay; (ii) Claims that in any way relate to any employee benefit program; (iii) Claims
that I have irrevocable or vested rights to severance or similar benefits or to
post-employment health or group insurance benefits; (iv) any Claim, such as a benefit claim,
that was explicitly or implicitly denied before I signed this Release; (v) any Claim I might
have for extra benefits as a consequence of payments I receive because of signing this
Release; or (vi) any Claim to attorneys’ fees or other indemnities.

     3.3. Unknown Claims. I understand that I am releasing Claims that I may not know about. That
is my knowing and voluntary intent, even though I recognize that someday I might learn that some or
all of the facts I currently believe to be true are untrue and even though I might then regret
having signed this Release. Nevertheless, I am assuming that risk and I agree that this Release
shall remain effective in all respects in any such case. I expressly waive all rights I might have
under any law that is intended to protect me from waiving unknown claims. I understand the
significance of doing so.

I expressly waive the protection of Section 1542 of the Civil Code of the State of
California, which states that:

A general release does not extend to claims which the creditor does
not know or suspect to exist in his or her favor at the time of
executing the release, which if known by him or her must have
materially affected his or her settlement with the debtor.

     3.4. Released Parties. The Released Parties are the Company, all current or former related
companies, partnerships, or joint ventures, and, with respect to each of them, all of the Company’s
or such related entities’ predecessors and successors, and, with respect to each such entity, all
of its past, present, and future employees, officers, directors, stockholders, owners,
representatives, assigns, attorneys, agents, insurers, employee benefit programs (and the trustees,
administrators, fiduciaries, and insurers of such programs), and any other persons acting by,
through, under, or in concert with any of the persons or entities listed in this subsection, and
their successors.

charges, if any, I have filed against any Released Party with any agency or court. I promise to

complaint, or charge to withdraw from the matter or dismiss the matter with prejudice.

     4.3. Company Property. I agree to immediately return to the Company all files, memoranda,
documents, records, copies of the foregoing, credit cards, keys, and any other property of the
Company or its affiliates that are in my possession. I specifically agree that the Company will

Company’s property back to the Company.

     4.4. Taxes. I am responsible for paying any taxes on amounts I receive because I signed this
Release and I agree that the Company is to withhold all taxes it determines it is legally required
to withhold.

     4.5. Employment Agreement Terms. I understand and agree that my Employment Agreement contains
the following terms, which I specifically reaffirm and incorporate in this Agreement. I understand
and agree that the Company would not pay me the Severance Pay described in section 2.1 absent my
agreement and reaffirmation of the following provisions of my Employment Agreement.

          4.5.1. Non-Solicitation of Employees. I agree that I will not, either directly or indirectly,
for my own account or either as agent, servant or employee, or as a shareholder of any corporation,
or member of any firm, solicit the employment of any employee of the Company, its parents,
subsidiaries, affiliates, successors or assigns, for a period of three years following October 20,
2006. I understand that the Company is paying me the Severance Pay described in section 2.1 of
this Agreement in reliance upon my agreement not to solicit the Company’s employees.

          4.5.2. Termination of Non-Compete Provision. I understand that the Company has agreed that

development of raw land for residential construction or in the construction and sale of single
family homes shall be null and void and of no effect.

     4.6. Ownership of Claims. I have not assigned or transferred any Claim I am releasing, nor
have I purported to do so.

     4.7. Nonadmission of Liability. I agree not to assert that this Release is an admission of
guilt or wrongdoing and I acknowledge that the Released Parties do not believe or admit that

Page 6 of 10

 

 

any of them has done anything wrong.

     4.8. No Disparagement. I agree not to criticize, denigrate, or disparage any Released Party.

     4.9. Nondisclosure. I acknowledge that I possess secret, confidential, or proprietary
information or trade secrets concerning the operations, future plans, or business methods of the
Company and its affiliates. I agree that the Company and its affiliates would be severely damaged
if I used or disclosed this information. To prevent this harm, I have made the following promises
and I acknowledge that the Company would be irreparably harmed if I broke any of them; these
promises supersede other similar promises I may have made only to the extent that these promises
are more protective of the Company’s interests, as it determines:

          4.9.1. Promise Not to Disclose. I promise never to use or disclose any such information before
it has become generally known within the relevant industry through no fault of my own. I agree that
this promise will never expire.

     4.10. Implementation. I agree to sign any documents and do anything else that is necessary in
the future to implement this Release.

     4.11. Future Cooperation. I agree that as a named executive officer of the Company certain
disclosures of my compensation and affiliated transactions with the Company are required to be
publicly disclosed by the Company under the Securities Exchange Act of 1934, as amended, and I
agree to provide any necessary information to the Company regarding myself as the Company requests,
including completing the required Directors and Officers Questionnaire. Additionally I agree to
cooperate, including meeting with the Company’s counsel on a reasonable basis, in the defense or
prosecution of any litigation to which the Company is a party.

     4.12. Agreement Not To Sue. I represent that I will not in the future file any lawsuit or
complaint against the Released Parties based on the Claims purportedly released in this Release. I
promise never to seek any damages, remedies, or other relief for myself personally (any right to
which I hereby waive) by filing or prosecuting a charge with any administrative agency with respect
to any Claim purportedly released by this Release. Notwithstanding the forgoing, nothing in this
Agreement shall preclude me from bringing suit to challenge the validity or enforceability of this
Agreement under the Age Discrimination in Employment Act [29 U.S.C. § 620, et seq.] as amended by
the Older Workers Benefit Protection Act. Nor shall anything in this Agreement be interpreted as
preventing or precluding my participation in any investigation or proceeding conducted by the Equal
Employment Opportunity Commission. Nor shall anything in this Agreement be interpreted as
prohibiting me from filing a charge, including a challenge to the validity of the waiver agreement,
with the EEOC pursuant to the Age Discrimination in Employment Act as amended.

     4.13. Other Representations. I have not suffered any job-related wrongs or injuries for which
I might still be entitled to compensation or relief, such as an injury for which I might receive a
workers’ compensation award in the future. I acknowledge and agree that I have not

OWBPA Severance Agreement

Page 7 of 10

 

 

suffered any discrimination on account of my age, sex, race, national origin, marital status,
sexual orientation, physical disability, mental disability, marital status, medical condition, or
any other protected status, and that none of these ever has been an adverse factor used against me
by any Released Party. I further acknowledge that I have been paid all wages and/or commissions
owing to me. I understand that the Company relied on these representations in entering into this
Release with me.

5. Consequences of Violating My Promises

     5.1. General Consequences. I agree to pay the reasonable attorneys’ fees and any damages the
Released Parties may incur as a result of my breaching a promise I made in this Release (such as by
suing a Released Party over a released Claim) or if any representation I made in this Release was
false when made. I acknowledge that the Company would be irreparably harmed by any actual or
threatened violation of Section 4.9 that involves disclosure or use of confidential information or
trade secrets and that the Company will be entitled to an injunction prohibiting me from committing
any such violation.

6. Consideration of Release.

     6.1. I acknowledge that, before signing this Agreement, I was given a period of at least 45
calendar days to consider this Agreement. I further acknowledge that I have received the listing
of people effected by the Company’s recent reduction in force in the Southern California Region,
attached hereto as Exhibit “A”. I understand that if I fail to return this Agreement to the
Company by December 5, 2006, as indicated at the top of this Agreement, that this Agreement and the
offers contained in it will be withdrawn, null and void. I also acknowledge that I have seven days
after I sign this Agreement to revoke my agreement to it by sending a written revocation notice to
the Company c/o Paula Hunter-Perkins D.R. Horton, Inc., 301 Commerce Street, Suite 500, Fort Worth,

to consider this Agreement before signing it; (2) I carefully read this Agreement; (3) I fully
understand it; (4) I am entering into it voluntarily; (5) I am receiving valuable consideration in
exchange for my execution of this Agreement that I would not otherwise be entitled to receive; (6)

understand that this Agreement waives any claims or rights I may have pursuant to the Age
Discrimination in Employment Act, as amended, except any such claims arising under said Act which
may arise after I sign this Agreement; (8) I understand that this Agreement does not prevent me
from bringing a suit to challenge the validity of this Agreement as it applies to the claims
seeking to enforce the ADEA; and, (9) I understand that this Agreement does not prohibit me from

agreement may not be modified or canceled in any manner except by a writing signed by both me and
an authorized Company official. I acknowledge that the Company has made no representations or

remain fully enforceable.

     7.2. Successors. This Release binds my heirs, administrators, representatives, executors,

convenience of reference and shall not be used in the interpretation of this Release. Except to the

the State of California (excluding any that mandate the use of another jurisdiction’s laws).

     7.4. Counterparts; Facsimile Signature. This Agreement may be executed in two or more
counterparts, each of which shall be deemed an original, but all of which shall constitute one and
the same written agreement. I and the Company agree that a facsimile signature shall be valid for
