duties hereunder subject to company policies and procedures.

     5. Termination of Employment. The date on which Executive’s employment by the Company
ceases, under any of the following circumstances, shall be defined herein as the “Termination
Date.”

          (a) Termination for Cause.

               (i) Termination: Payment of Accrued Salary and Vacation. The Board may terminate Executive’s
employment with the Company at any time for cause, immediately upon written notice to Executive of
the circumstances leading to such termination for cause. If Executive’s employment is terminated
for cause, Executive shall receive payment for all accrued salary and vacation time through the
Termination Date, which in this event shall be the date upon which notice of termination is given.
The Company shall have no obligation to pay severance of any kind nor to make any payment in lieu
of notice if Executive is terminated for cause.

               (ii) Definition of Cause. “Cause” means the occurrence or existence of any of the following
with respect to Executive, as reasonably determined by the Board: (A) the repeated failure to obey
a lawful directive of the Board or President relating to the business of the Company after at least
one written notice of such failure has been given; (B) a material breach by Executive of his duty
not to engage in any transaction that represents, directly or indirectly, self-dealing with the
Company which has not been approved by the Board, or a material breach by Executive of the terms of
his employment, if in any such case such material breach remains uncured after the lapse of 30 days
following the date that the Company has given Executive written notice thereof; (C) any act of
dishonesty, misappropriation, embezzlement, intentional fraud or similar conduct involving the
Company; (D) the conviction or the plea of nolo contendere or the equivalent in respect of a felony
involving moral turpitude (but in no event relating to any violation of any obscenity laws with
respect to publications carried by the Company); (E) any intentional damage of a material nature to
any property of the Company; or (F) the repeated non-prescription use of any controlled substance
or the repeated use of alcohol or any other non-controlled substance which, in the reasonable
determination of the Board renders Executive unfit to serve in his capacity as an officer or
employee of the Company.

          (b) Voluntary Termination. Executive may voluntarily terminate his employment with the
Company at any time upon 180 days’ prior written notice. On the Termination Date, Executive shall
receive payment for all accrued salary through the Termination Date, after which no further
compensation of any kind or severance payment will be payable under this Agreement.

          (c) Termination upon Disability. The Company may terminate Executive’s employment in
the event Executive suffers a disability that renders Executive unable to perform the essential
functions of his position, even with reasonable accommodation in compliance with the Americans with
Disabilities Act, for six consecutive months within any twelve month period.

3

 

After the Termination Date, which in this event shall be the date upon which notice of termination
is given, no further compensation will be payable under this Agreement.

          (d) Termination Without Cause. The Company may terminate Executive’s employment
without “cause” (as defined above) at any time upon 30 days’ prior written notice. On the
Termination Date, Executive shall receive payment for all accrued salary through the Termination
Date and thereafter the Company shall pay Executive severance for twelve months or through the term
of this Agreement, whichever is longer, at the rate Executive is then being compensated. Standard
withholdings for taxes and social security and the like shall be deducted from the severance
payment. The severance shall be payable in equal installments on each of the Company’s regular
payroll dates during the severance period commencing on the first such payroll date following the
Termination Date. In addition, medical, dental, prescription and life insurance benefits shall
continue to be provided, at the cost of the Company, during the period of severance payments or
though the remaining term of this Agreement, whichever is greater. Any cash bonuses or other
payments that would have been earned in the fiscal year in which Executive is terminated will be
paid to Executive on a pro rata basis at the same time as other executives receive such bonuses or
payments.

          (e) Fundamental Changes.  If the Company (i) materially diminishes Executive’s duties,
authority, or responsibility, (ii) reduces Executive’s compensation, or (iii) breaches this
Agreement in any material respect, Executive may terminate his employment provided that the
Executive has given the Company 15 days’ written notice prior to such termination and the Company
has not cured such diminution or breach, as the case may be, by the end of such 15-day period. If
the Company relocates its corporate offices outside a triangular area formed by Princeton, New
Jersey, Doylestown, Pennsylvania, and Langhorne, Pennsylvania, then after one year Executive may
terminate his employment provided that the Executive has given the Company 90 days’ written notice
prior to such termination. A termination under the circumstances set forth in this subsection (e)
shall be treated as a Company termination without cause, and Executive shall be entitled to the
severance payments provided in Section 5(d).

     6. Proprietary Information Obligations. Executive will execute, or has executed and
hereby ratifies and affirms his obligations under, the Company’s standard form non-disclosure
agreement in the form attached hereto as Exhibit C.

     7. Noninterference. While employed by the Company and for the period of two years
thereafter, Executive agrees not to interfere with the business of the Company by directly or
indirectly soliciting, attempting to solicit, inducing, or otherwise causing any employee who is an
employee of the Company at the time of such solicitation to terminate his or her employment in
order to become an employee, consultant or independent contractor to or for any other employer.

     8. Noncompetition. Executive acknowledges that his employment pursuant to this
Agreement will give him the opportunity to maintain the business relationships with book and
magazine printers and publishers located in the United States and Canada that he developed prior to
the sale of The Clark Group, Inc., as a result of which Executive will be able to adversely affect
the goodwill of the Company’s business if he competes against it after the end of his

4

 

employment, even though such competition may not occur for several years after the date hereof.
Accordingly, Executive covenants and agrees that, during the term of this Agreement (including any
renewals thereof) and for a period of two (2) years after the last payment that Executive receives
hereunder as a result of termination for cause as defined in Section 5(a) or the voluntary
termination of his employment by Executive pursuant to Section 5(b) and for a period of one (1)
year after the last payment that Executive receives hereunder as a result of termination without
cause pursuant to Section 5(d) or a fundamental change pursuant to Section 5(e), Executive will
not, in the United States and Canada, either directly or indirectly, on his own behalf or as a
proprietor, partner, agent, broker, consultant, lender, guarantor, shareholder (other than
ownership of less than one percent (1%) of the stock of a publicly-owned corporation whose shares
are listed and traded on a national securities exchange), director, officer or in any other
capacity or manner whatsoever, without the prior written consent of the Company, engage in any
activity in which the Company is engaged prior to or at the time of, as applicable, the termination
of Executive’s employment with the Company.

     9. Remedies. Executive acknowledges that a breach or threatened breach by Executive of
any of the provisions of Sections 6, 7, or 8 will result in the Company suffering irreparable harm
that cannot be calculated or fully or adequately compensated by recovery of damages alone.
Accordingly, Executive agrees that the Company shall be entitled to interim, interlocutory and
permanent injunctive relief, specific performance and other equitable remedies, in addition to any
other relief to which the Company may become entitled should there be such a breach or threatened
breach.

be of no further force and effect.

          (d) Counterparts. This Agreement may be executed on separate counterparts, any one of

therefor satisfactory to the Trustee has been made;

          (3) Securities as to which Defeasance has been effected pursuant to Section 1302; and

Securities are valid obligations of the Company;

provided, however, that in determining whether the Holders of the requisite
principal amount of the Outstanding Securities have given, made or taken any request, demand,
authorization, direction, notice, consent, waiver or other action hereunder as of any date, (A) the
principal amount of an Original Issue Discount Security which shall be deemed to be Outstanding
shall be the amount of the principal thereof which would be due and payable as of such date upon
acceleration of the Maturity thereof to such date pursuant to Section 502, (B) if, as of such date,

specified or determined as contemplated by Section 301, (C) the principal amount of a Security
denominated in one or more foreign currencies or currency units which shall be deemed to be

notice, consent, waiver or other action, only Securities which a responsible officer of the Trustee

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

     SECTION 104. Acts of Holders; Record Dates.

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

-9-

 

purpose of this Indenture and (subject to Section 601) conclusive in favor of the Trustee and
the Company, if made in the manner provided in this Section.

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

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

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

     The Company may set any day as a record date for the purpose of determining the Holders of
Outstanding Securities of any series entitled to give, make or take any request, demand,
authorization, direction, vote, notice, consent, waiver or other action provided or permitted by
this Indenture to be given, made or taken by Holders of Securities of such series, provided
that the Company may not set a record date for, and the provisions of this paragraph shall
not apply with respect to, the giving or making of any notice, declaration, request or direction
referred to in the next paragraph. If any record date is set pursuant to this paragraph, the
Holders of Outstanding Securities of the relevant series on such record date, and no other Holders,
shall be entitled to take the relevant action, whether or not such Holders remain Holders after
such record date; provided that no such action shall be effective hereunder unless
taken on or prior to the applicable Expiration Date by Holders of the requisite principal amount of
Outstanding Securities of such series on such record date. Nothing in this paragraph shall be
construed to prevent the Company from setting a new record date for any action for which a record
date has previously been set pursuant to this paragraph (whereupon the record date previously set
shall automatically and with no action by any Person be canceled and of no effect), and nothing in
this paragraph shall be construed to render ineffective any action taken by Holders of the
requisite principal amount of Outstanding Securities of the relevant series on the date such action
is taken. Promptly after any record date is set pursuant to this paragraph, the Company, at its own
expense, shall cause notice of such record date, the proposed action by Holders and the applicable
Expiration Date to be given to the Trustee in writing and to each Holder of Securities of the
relevant series in the manner set forth in Section 106.

     The Trustee may set any day as a record date for the purpose of determining the Holders of
Outstanding Securities of any series entitled to join in the giving or making of (i) any Notice of
Default, (ii) any declaration of acceleration referred to in Section 502, (iii) any request to
institute proceedings referred to in Section 507(2) or (iv) any direction referred to in Section
512, in each

-10-

 

case with respect to Securities of such series. If any record date is set pursuant to this
paragraph, the Holders of Outstanding Securities of such series on such record date, and no other
Holders, shall be entitled to join in such notice, declaration, request or direction, whether or
not such Holders remain Holders after such record date; provided that no such
action shall be effective hereunder unless taken on or prior to the applicable Expiration Date by
Holders of the requisite principal amount of Outstanding Securities of such series on such record
date. Nothing in this paragraph shall be construed to prevent the Trustee from setting a new record
date for any action for which a record date has previously been set pursuant to this paragraph
(whereupon the record date previously set shall automatically and with no action by any Person be
canceled and of no effect), and nothing in this paragraph shall be construed to render ineffective
any action taken by Holders of the requisite principal amount of Outstanding Securities of the
relevant series on the date such action is taken. Promptly after any record date is set pursuant to
this paragraph, the Trustee, at the Company’s expense, shall cause notice of such record date, the
proposed action by Holders and the applicable Expiration Date to be given to the Company in writing
and to each Holder of Securities of the relevant series in the manner set forth in Section 106.

     With respect to any record date set pursuant to this Section, the party hereto which sets such
record dates may designate any day as the “Expiration Date” and from time to time may change the
Expiration Date to any earlier or later day; provided that no such change shall be
effective unless notice of the proposed new Expiration Date is given to the other party hereto in
writing, and to each Holder of Securities of the relevant series in the manner set forth in Section
106, on or prior to the existing Expiration Date. If an Expiration Date is not designated with
respect to any record date set pursuant to this Section, the party hereto which set such record
date shall be deemed to have initially designated the 180th day after such record date as the
Expiration Date with respect thereto, subject to its right to change the Expiration Date as
provided in this paragraph. Notwithstanding the foregoing, no Expiration Date shall be later than
the 180th day after the applicable record date.

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

     SECTION 105. Notices, Etc., to Trustee and Company.

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

          (1) the Trustee by any Holder or by the Company shall be sufficient for every purpose
hereunder if made, given, furnished or filed in writing (or by facsimile transmission ((213)
615-6197), provided that oral confirmation of receipt shall have been received) to
or with the Trustee at its Corporate Trust Office, or

          (2) the Company by the Trustee or by any Holder shall be sufficient for every purpose
hereunder (unless otherwise herein expressly provided) if in writing and mailed, first-class

-11-

 

postage prepaid, to the Company addressed to it at the address of its principal office
specified in the first paragraph of this instrument or at any other address previously furnished in
writing to the Trustee by the Company, Attention: Chief Financial Officer, with a copy to the
Secretary; provided that notice shall not be deemed to be given until received by
the Company.

     SECTION 106. Notice to Holders; Waiver.

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

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

     SECTION 107. Conflict with Trust Indenture Act.

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

     SECTION 108. Effect of Headings and Table of Contents.

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

     SECTION 109. Successors and Assigns.

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

-12-

 

     SECTION 110. Separability Clause.

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

     SECTION 111. Benefits of Indenture.

     Nothing in this Indenture or in the Securities, express or implied, shall give to any Person,
other than the parties hereto and their successors hereunder, the holders of Senior Debt (if the
subordination provisions of this Indenture are applicable to such series of Securities) and the
Holders, any benefit or any legal or equitable right, remedy or claim under this Indenture.

     SECTION 112. Governing
Law; Jurisdiction; Consent to Service of Process.

COURT. EACH OF THE PARTIES HERETO AND EACH HOLDER AGREES THAT A FINAL JUDGMENT IN ANY SUCH ACTION
OR PROCEEDING SHALL BE CONCLUSIVE AND MAY BE ENFORCED IN OTHER JURISDICTIONS BY SUIT ON THE
JUDGMENT OR IN ANY OTHER MANNER PROVIDED BY LAW.

     (c)      WAIVER OF VENUE. EACH OF THE TRUSTEE, COMPANY AND EACH HOLDER IRREVOCABLY AND
UNCONDITIONALLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY OBJECTION THAT IT
MAY NOW OR HEREAFTER HAVE TO THE LAYING OF VENUE OF ANY SUIT, ACTION OR PROCEEDING ARISING OUT OF

Indenture, upon surrender of this Security, together with the conversion notice hereon duly

provided in the Indenture), no adjustment is to be made on conversion for interest accrued
hereon or for dividends on shares of Common Stock issued on conversion. The Company is not required

the basis of the current market value of such fractional interest as provided in the Indenture. The
conversion price is subject to adjustment as provided in the Indenture. In addition, the Indenture
provides that in case of certain consolidations or mergers to which the Company is a party or the
sale of substantially all of the assets of the Company, the Indenture shall be amended, without the
consent of any Holders of Securities, so that this Security, if then outstanding, will be
convertible thereafter, during the period this Security shall be convertible as specified above,
only into the kind and amount of securities, cash and other property receivable upon the
consolidation, merger or sale by a holder of the number of shares of Common Stock into which this
Security might have been converted immediately prior to such consolidation, merger or sale
(assuming such holder of Common Stock failed to exercise any rights of election and received per
share the kind and amount received per share by a plurality of non-electing shares). In the event
of conversion of this Security in part only, a new Security or Securities for the unconverted
portion hereof shall be issued in the name of the Holder hereof upon the cancellation hereof.]

the extent and in the manner provided in the Indenture, subordinate and subject in right of payment
to the prior payment in full of all Senior Indebtedness of the Company, and this Security is issued
subject to such provisions of the Indenture with respect thereto. Each Holder of this Security, by
accepting the same (a) agrees to and shall be bound by such provisions, (b) authorizes and directs
the Trustee on his behalf to take such action as may be necessary to appropriate to effectuate the
subordination so provided and (c) appoints the Trustee his attorney-in-fact for any and all such
purposes.]

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

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

the modification of the rights and obligations of the Company and the rights of the Holders of the
Securities of each series to be affected under the Indenture at any time by the Company and the
Trustee with the consent of the Holders of at least a majority in principal amount of the
Securities at the time Outstanding of each series to be affected. The Indenture also contains
provisions permitting the Holders of specified percentages in principal amount of the Securities of
each series at the time Outstanding, on behalf of the Holders of all Securities of such series, to
waive compliance by the Company with certain provisions of the Indenture and certain past defaults
under the Indenture and their consequences. Any such consent or waiver by the Holder of this
Security shall be conclusive and binding upon such Holder and upon all future Holders of this
Security and of any Security issued upon the registration of transfer hereof or in exchange herefor
or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.

     As provided in and subject to the provisions of the Indenture, the Holder of this Security

appointment of a receiver or trustee or for any other remedy thereunder, unless such Holder shall
have previously given the Trustee written notice of a continuing Event of Default with respect to
the Securities of this series, the Holders of not less than 25% in principal amount of the
Securities of this series at the time Outstanding shall have made written request to the Trustee to
institute proceedings in respect of such Event of Default as Trustee and offered the Trustee
reasonable indemnity, and the Trustee shall not have received from the Holders of a majority in
principal amount of Securities of this series at the time Outstanding a direction inconsistent with
such request, and shall have failed to institute any such proceeding, for 60 days after receipt of
such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted
by the Holder of this Security for the enforcement of any payment of principal hereof or any
premium or interest hereon on or after the respective due dates expressed herein.

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

for registration of transfer at the office or agency of the Company in any place where the
principal of and any premium and interest on this Security are payable, duly endorsed by, or

Security Registrar duly executed by, the Holder hereof or its attorney duly authorized in writing,

exchange securities for, shares of Common Stock of the Company or other securities or property or
cash in lieu of such Common Stock or other securities or property, or any combination thereof, and
any corresponding changes to the provisions of this Indenture as then in effect;

          (19) if applicable, that any Securities of the series shall be issuable in whole or in part in
the form of one or more Global Securities and, in such case, the respective Depositaries for such
Global Securities, the form of any legend or legends which shall be borne by any such Global
Security in addition to or in lieu of that set forth in Section 204 and any circumstances in
addition to or in lieu of those set forth in Clause (2) of the last paragraph of Section 305 in
which any such Global Security may be exchanged in whole or in part for Securities registered, and
any transfer of such Global Security in whole or in part may be registered, in the name or names of
Persons other than the Depositary for such Global Security or a nominee thereof;

          (20) 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

-26-

 

          (21) any Authenticating Agents, Paying Agents or Security Registrars;

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

          (23) the terms, if any, of the transfer, mortgage, pledge or assignment as security for the

          (26) any other terms of the series (which terms shall not be inconsistent with the provisions
of this Indenture, except as permitted by Section 901(5)).

     All Securities of any one series shall be substantially identical except as to denomination
and except as may otherwise be provided in or pursuant to the Board Resolution referred to above
and (subject to Section 303) set forth, or determined in the manner provided, in the Officers’
Certificate referred to above or in any such indenture supplemental hereto. All Securities of any
one series need not be issued at the same time and, unless otherwise provided, a series may be
reopened for issuances of additional Securities of such series.

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

     The Securities shall be subordinated in right of payment to Senior Debt as provided in Article
Fifteen only to the extent that the Board Resolution, Officers’ Certificate or supplemental
indenture establishing such series of Securities provides that such subordination provisions are
applicable to such series.

     SECTION 302. Denominations.

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

-27-

 

     SECTION 303. Execution, Authentication, Delivery and Dating.

     The Securities shall be executed on behalf of the Company by its Chairman of the Board, its
principal financial officer, its Chief Executive Officer, its President or one of its Vice
Presidents, its Treasurer or its Assistant Treasurer, attested by its Secretary or one of its
Assistant Secretaries. The signature of any of these officers on the Securities may be manual or
facsimile.

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

     At any time and from time to time after the execution and delivery of this Indenture, the
Company may deliver Securities of any series executed by the Company to the Trustee for
authentication, together with a Company Order for the authentication and delivery of such
Securities, and the Trustee in accordance with the Company Order (which may provide that Securities
that are the subject thereof will be authenticated and delivered by the Trustee from time to time
upon the telephonic or written order of Persons designated in said Company Order and that such
Persons are authorized to determine such terms and conditions of said Securities as are specified
in the Company Order) shall authenticate and deliver such Securities. If the form or terms of the
Securities of the series have been established by or pursuant to one or more Board Resolutions as
permitted by Sections 201 and 301, in authenticating such Securities, and accepting the additional
responsibilities under this Indenture in relation to such Securities, the Trustee shall be entitled
to receive, and (subject to Section 601) shall be fully protected in relying upon, a copy of such
Board Resolution, the Officers’ Certificate setting forth the terms of the series and an Opinion of
Counsel, with such Opinion of Counsel stating,

          (1) if the form of such Securities has been established by or pursuant to Board Resolution as
permitted by Section 201, that such form has been established in conformity with the provisions of
this Indenture;

          (2) if the terms of such Securities have been established by or pursuant to Board Resolution
as permitted by Section 301, that such terms have been established in conformity with the
provisions of this Indenture; and

          (3) that such Securities, when authenticated and delivered by the Trustee and issued by the
Company in the manner and subject to any conditions specified in such Opinion of Counsel, will
constitute valid and legally binding obligations of the Company enforceable in accordance with
their terms, subject to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and
similar laws of general applicability relating to or affecting creditors’ rights and to general
equity principles.

     However, the Trustee shall not be required to authenticate such Securities if the issue of
such Securities pursuant to this Indenture will affect the Trustee’s own rights, duties or
immunities under

-28-

 

the Securities and this Indenture or otherwise in a manner which is not reasonably acceptable
to the Trustee.

     Notwithstanding the provisions of Section 301 and of the preceding paragraph, if all
Securities of a series are not to be originally issued at one time, it shall not be necessary to
deliver the Officers’ Certificate otherwise required pursuant to Section 301 or the Company Order
and Opinion of Counsel otherwise required pursuant to such preceding paragraph at or prior to the
authentication of each Security of such series if such documents are delivered at or prior to the
authentication upon original issuance of the first Security of such series to be issued.

     Each Security shall be dated the date of its authentication.

     No Security shall be entitled to any benefit under this Indenture or be valid or obligatory
for any purpose unless there appears on such Security a certificate of authentication substantially
in the form provided for herein executed by the Trustee by manual signature, and such certificate
upon any Security shall be conclusive evidence, and the only evidence, that such Security has been
duly authenticated and delivered hereunder. Notwithstanding the foregoing, if any Security shall
have been authenticated and delivered hereunder but never issued and sold by the Company, and the
Company shall deliver such Security to the Trustee for cancellation as provided in Section 309, for
all purposes of this Indenture such Security shall be deemed never to have been authenticated and
delivered hereunder and shall never be entitled to the benefits of this Indenture.

     SECTION 304. Temporary Securities.

     Pending the preparation of definitive Securities of any series, the Company may execute, and
upon Company Order the Trustee shall authenticate and deliver, temporary Securities which are
printed, lithographed, typewritten, mimeographed or otherwise produced, in any authorized
denomination, substantially of the tenor of the definitive Securities in lieu of which they are
issued and with such appropriate insertions, omissions, substitutions and other variations as the
officers executing such Securities may determine, as evidenced by their execution of such
Securities.

     If temporary Securities of any series are issued, the Company will cause definitive Securities
of that series to be prepared without unreasonable delay. After the preparation of definitive
Securities of such series, the temporary Securities of such series shall be exchangeable for
definitive Securities of such series upon surrender of the temporary Securities of such series at
the office or agency of the Company in a Place of Payment for that series, without charge to the
Holder. Upon surrender for cancellation of any one or more temporary Securities of any series, the
Company shall execute and the Trustee shall authenticate and deliver in exchange therefor one or
more definitive Securities of the same series, of any authorized denominations and of like tenor
and aggregate principal amount. Until so exchanged, the temporary Securities of any series shall in
all respects be entitled to the same benefits under this Indenture as definitive Securities of such
series and tenor.

-29-

 

     SECTION 305. Registration; Registration of Transfer and Exchange.

     The Company shall cause to be kept at the Corporate Trust Office of the Trustee a register
(the register maintained in such office and in any other office or agency of the Company in a Place
of Payment being herein sometimes collectively referred to as the “Security Register”) in which,
subject to such reasonable regulations as it may prescribe, the Company shall provide for the
registration of Securities and of transfers of Securities. The Trustee is hereby appointed
“Security Registrar” for the purpose of registering Securities and transfers of Securities as
herein provided. The Company may change any Security Registrar without notice to any Holder. The
Company or any of its Subsidiaries may act as Security Registrar.

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

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

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

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

     No service charge shall be made for any registration of transfer or exchange of Securities,
but the Company may require payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in connection with any registration of transfer or exchange of
Securities, other than exchanges pursuant to Section 304, 906 or 1107 not involving any transfer.

     If the Securities of any series (or of any series and specified tenor) are to be redeemed in
part, the Company shall not be required (A) to issue, register the transfer of or exchange any
Securities of that series (or of that series and specified tenor, as the case may be) during a
period beginning at the opening of business 15 days before the day of the mailing of a notice of
redemption of any such Securities selected for redemption under Section 1103 and ending at the
close of business on the day of such mailing, or (B) to register the transfer of or exchange any
Security so selected for redemption in whole or in part, except the unredeemed portion of any
Security being redeemed in part.

-30-

 

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

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

          (2) Notwithstanding any other provision in this Indenture, no Global Security may be exchanged
in whole or in part for Securities registered, and no transfer of a Global Security in whole or in
part may be registered, in the name of any Person other than the Depositary for such Global
Security or a nominee thereof unless (A) such Depositary (i) has notified the Company that it is
unwilling or unable to continue as Depositary for such Global Security or (ii) has ceased to be a
clearing agency registered under the Exchange Act, (B) there shall have occurred and be continuing
an Event of Default with respect to such Global Security or (C) there shall exist such
circumstances, if any, in addition to or in lieu of the foregoing as have been specified for this
purpose as contemplated by Section 301.

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

          (4) Every Security authenticated and delivered upon registration of transfer of, or in
exchange for or in lieu of, a Global Security or any portion thereof, whether pursuant to this
Section, Section 304, 306, 906 or 1107 or otherwise, shall be authenticated and delivered in the
form of, and shall be, a Global Security, unless such Security is registered in the name of a
Person other than the Depositary for such Global Security or a nominee thereof.

     SECTION 306. Mutilated, Destroyed, Lost and Stolen Securities.

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

     If there shall be delivered to the Company and the Trustee (i) evidence to their satisfaction
of the destruction, loss or theft of any Security and (ii) such security or indemnity as may be
required by them to save each of them and any agent of either of them harmless, then, in the
absence of notice to the Company or the Trustee that such Security has been acquired by a bona fide
purchaser, the Company shall execute and the Trustee shall authenticate and deliver, in lieu of any
such destroyed, lost or stolen Security, a new Security of the same series and of like tenor and
principal amount and bearing a number not contemporaneously outstanding.

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

-31-

 

     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 307. Payment of Interest; Interest Rights Preserved.

     Except as otherwise provided as contemplated by Section 301 with respect to any series of
Securities, interest on any Security which is payable, and is punctually paid or duly provided for,
on any Interest Payment Date shall be paid to the Person in whose name that Security (or one or
more Predecessor Securities) is registered at the close of business on the Regular Record Date for
such interest; [provided that on the maturity date
for any series of Securities, the Company
will pay accrued and unpaid interest to the Person to whom the
Company pays the principal amount, instead of
the Person in whose name that Security (or one or more Predecessor Securities) is registered at the
close of business on the Regular Record Date.]

     In the case of Securities represented by a Global Security registered in the name of or held
by a Depository or its nominee, unless otherwise specified by Section 301, payment of principal,
premium, if any, and interest, if any, will be made to the Depository or its nominee, as the case
may be, as the registered owner or Holder of such Global Security. None of the Company, the Trustee
and the Paying Agent, any Authenticating Agent or the Security Registrant for such Securities will
have any responsibility or liability for any aspect of the records relating to or payments made on
account of a beneficial ownership interest in a Global Security or maintaining, supervising or
reviewing any records relating to such beneficial ownership interests.

     Any interest on any Security of any series which is payable, but is not punctually paid or
duly provided for, on any Interest Payment Date (herein called “Defaulted Interest”) shall
forthwith cease to be payable to the Holder on the relevant Regular Record Date by virtue of having
been such Holder, and such Defaulted Interest may be paid by the Company, at its election in each
case, as provided in Clause (1) or (2) below:

          (1) The Company may elect to make payment of any Defaulted Interest to the Persons in whose
names the Securities of such series (or their respective Predecessor Securities) are registered at
the close of business on a Special Record Date for the payment of such Defaulted Interest, which
shall be fixed in the following manner. The Company shall notify the Trustee in

-32-

 

writing of the amount of Defaulted Interest proposed to be paid on each Security of such
series and the date of the proposed payment, and at the same time the Company shall deposit with
the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such
Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit prior to
the date of the proposed payment, such money when deposited to be held in trust for the benefit of
the Persons entitled to such Defaulted Interest as in this Clause provided. Thereupon the Trustee
shall fix a Special Record Date for the payment of such Defaulted Interest which shall be not more
than 15 days and not fewer than 10 days prior to the date of the proposed payment and not fewer
than 10 days after the receipt by the Trustee of the notice of the proposed payment. The Trustee
shall promptly notify the Company of such Special Record Date and, in the name and at the expense
of the Company, shall cause notice of the proposed payment of such Defaulted Interest and the
Special Record Date therefor to be given to each Holder of Securities of such series in the manner
set forth in Section 106, not fewer than 10 days prior to such Special Record Date. Notice of the
proposed payment of such Defaulted Interest and the Special Record Date therefor having been so
mailed, such Defaulted Interest shall be paid to the Persons in whose names the Securities of such
series (or their respective Predecessor Securities) are registered at the close of business on such
Special Record Date and shall no longer be payable pursuant to the following Clause (2).

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

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

     Subject to the provisions of Section 1402, in the case of any Security (or any part thereof)
which is converted after any Regular Record Date and on or prior to the next succeeding Interest
Payment Date (other than any Security the principal of (or premium, if any, on) which shall become
due and payable, whether at Stated Maturity or by declaration of acceleration or otherwise prior to
such Interest Payment Date), interest whose Stated Maturity is on such Interest Payment Date shall
be payable on such Interest Payment Date notwithstanding such conversion and such interest (whether
or not punctually paid or duly provided for) shall be paid to the Person in whose name that
Security (or any one or more Predecessor Securities) is registered at the close of business on such
Regular Record Date. Except as otherwise expressly provided in the immediately preceding sentence
or in Section 1402, in the case of any Security (or any part thereof) which is converted, interest
whose Stated Maturity is after the date of conversion of such Security (or such part thereof) shall
not be payable.

-33-

 

     SECTION 308. Persons Deemed Owners.

     Prior to due presentment of a Security for registration of transfer, the Company, the Trustee
and any agent of the Company or the Trustee may treat the Person in whose name such Security is
registered as the owner of such Security for the purpose of receiving payment of principal of and
any premium and (subject to Section 307) any interest on such Security and for all other purposes
whatsoever, whether or not such Security be overdue, and neither the Company, the Trustee nor any
agent of the Company or the Trustee shall be affected by notice to the contrary.

     In the case of a Global Security, so long as the Depository for such Global Security, or its
nominee, is the registered owner of such Global Security, such Depository or such nominee, as the
case may be, will be considered the sole owner or Holder of the Securities represented by such
Global Security for all purposes under this Indenture. Except as provided in Section 305, owners of
beneficial interests in a Global Security will not be entitled to have Securities that are
represented by such Global Security registered in their names, will not receive or be entitled to
receive physical delivery of such Securities in definitive form and will not be considered the
owners or Holders thereof under this Indenture.

     Notwithstanding the foregoing, with respect to any Global Security, nothing herein shall (a)
prevent the Company, the Trustee, or any agent of the Company or the Trustee, from giving effect to
any written certification, proxy or other authorization furnished by a Depository or (b) impair, as
between a Depository and holders of beneficial interest in any Global Security, the operation of
customary practices governing the exercise of the rights of the Depository as Holder of such Global
Security.

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

     SECTION 309. Cancellation.

     All Securities surrendered for payment, redemption, registration of transfer or exchange or
for credit against any sinking fund payment shall, if surrendered to any Person other than the
Trustee, be delivered to the Trustee and shall be promptly canceled by it. The Company may at any
time deliver to the Trustee for cancellation any Securities previously authenticated and delivered
hereunder which the Company may have acquired in any manner whatsoever, and may deliver to the
Trustee (or to any other Person for delivery to the Trustee) for cancellation any Securities
previously authenticated hereunder which the Company has not issued and sold, and all Securities so
delivered shall be promptly canceled by the Trustee. No Securities shall be authenticated in lieu
of or in exchange for any Securities canceled as provided in this Section, except as expressly
permitted by this Indenture. All canceled Securities held by the Trustee shall be returned to the
Company, or upon request by the Company, deliver to the Company certificates of destruction with
respect thereto.

-34-

 

     SECTION 310. Computation of Interest.

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

     SECTION 311. CUSIP Numbers.

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

ARTICLE FOUR

covenants or terms expressly survive such satisfaction and discharge as provided herein or as

ARTICLE FIVE

REMEDIES

     SECTION 501. Events of Default.

     “Event of Default,” wherever used herein with respect to Securities of any series, means any
one of the following events (whatever the reason for such Event of Default and whether it shall be
occasioned by the provisions of Article Fifteen or be voluntary or involuntary or be effected by
operation of law or pursuant to any judgment, decree or order of any court or any order, rule or
regulation of any administrative or governmental body), except to the extent such event is
specifically deleted or modified as contemplated by Section 301 for the Securities of that series):

          (1) default in the payment of any interest upon any Security of that series when it becomes
due and payable, and continuance of such default for a period of 30 days; or

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

          (3) default in the deposit of any sinking fund payment, when and as due by the terms of a
Security of that series and continuance of such default for a period of 30 days; or

whose performance or whose breach is elsewhere in this Section specifically dealt with or which has
expressly been included in this Indenture solely for the benefit of series of Securities other than

of such series), and continuance of such default or breach for a period of 90 days after there has
been given, by registered or certified mail, to the Company by the Trustee or to the Company and

or proceeding under any applicable Federal or State bankruptcy, insolvency, reorganization or other
similar law or of any other case or proceeding to be adjudicated a bankrupt or insolvent, or the
consent by it to the entry of a decree or order for relief in respect of the Company or any of its
Significant Subsidiaries in an involuntary case or proceeding under any applicable Federal or State
bankruptcy, insolvency, reorganization or other similar law or to the commencement of any
bankruptcy or insolvency case or proceeding against it, or the filing by it of a petition or answer
or consent seeking reorganization or relief under any applicable Federal or State law, or the
consent by it to the filing of such petition or to the appointment of or taking possession by a

property, or the making by it of an assignment for the benefit of creditors, or the admission by it
in writing of its inability to pay its debts generally as they become due, or the taking of
corporate action by the Company or any of its Significant Subsidiaries in furtherance of any such
action; or

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

     SECTION 502. Acceleration of Maturity; Rescission and Annulment.

     If an Event of Default, other than an Event of Default specified in Sections 501(5) or 501(6)
solely with respect to the Company (but including an Event of Default referred to in those Sections
solely with respect to a Significant Subsidiary of the Company) with respect to Securities of any
series at the time Outstanding occurs and is continuing, then either the Trustee, by notice to the
Company, or the Holders of not less than 25% in principal amount of the Outstanding Securities of
that series, by notice to the Trustee and the Company, may declare the principal amount of, and
accrued and unpaid interest on, all the Securities of that series (or, if any Securities of that
series are Original Issue Discount Securities, such portion of the principal amount of such
Securities as may be specified by the terms thereof) to be due and payable immediately. In the case
of an Event of Default specified in Section 501(5) or 501(6) solely with respect to the Company
(and not solely with respect to any Significant Subsidiary of the Company) and with respect to
Securities of any series at the time Outstanding occurs, the principal amount of (or, if any
Securities of that series are Original Issue Discount Securities, such portion of the principal
amount of such Securities as may be specified by the terms thereof), and all accrued and unpaid
interest on, all the Securities of that series shall automatically become immediately due and
payable. To the extent a series of Securities provides that the subordination provisions of Article
Fifteen apply to such series, any payments by the Company on the Securities following any such
acceleration will be subject to the subordination provisions of Article Fifteen to the extent
provided therein.

     Notwithstanding the foregoing, for the first 180 days following any violation of any
obligations the Company may be deemed to have pursuant to Section 314(a)(1) of the Trust Indenture
Act or the Company’s other reporting and information delivery obligations with respect to filings
with the Commission as provided in Section 704, at the Company’s option, the sole remedy of the
Holders of the Securities shall be the accrual of additional interest on the Securities while such
Default exists at a rate of 0.25% per annum, payable semi-annually. In no event shall such
additional

-38-

 

interest accrue at a rate per annum in excess of 0.25% per annum, regardless of the number of
events or circumstances giving rise to the requirement to pay such additional interest.

     At any time after such acceleration with respect to Securities of any series, the Holders of a
majority in principal amount of the Outstanding Securities of that series, by written notice to the
Company and the Trustee, may rescind and annul such declaration and its consequences if

          (1) the recission would not conflict with any order or decree;

          (2) all Events of Default with respect to Securities of that series, other than the
non-payment of accelerated principal of or interest on Securities of that series, have been cured
or waived as provided in Section 513; and

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

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

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

               (C) to the extent that payment of such interest is lawful, interest upon overdue interest at
the rate or rates prescribed therefor in such Securities, and

               (D) all sums paid or advanced by the Trustee hereunder and the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel.

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

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

     The Company covenants that if

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

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

the Company will, upon demand of the Trustee, pay to it, for the benefit of the Holders of such
Securities, the whole amount then due and payable on such Securities for principal and any premium
and interest and, to the extent that payment of such interest shall be legally enforceable,
interest on any overdue principal and premium and on any overdue interest, at the rate or rates
prescribed therefor in such Securities, and, in addition thereto, such further amount as shall be
sufficient to cover the costs and expenses of collection, including the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel.

-39-

 

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

     SECTION 504. Trustee May File Proofs of Claim.

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

     No provision of this Indenture shall be deemed to authorize the Trustee to authorize or
consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement,
adjustment or composition affecting the Securities or the rights of any Holder thereof or to
authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.

     SECTION 505. Trustee May Enforce Claims Without Possession of Securities.

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

     SECTION 506. Application of Money Collected.

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

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

-40-

 

     SECOND: Subject to Article Fifteen (to the extent Article Fifteen is applicable to such series
of Securities), to the payment of the amounts then due and unpaid for principal of and any premium,
if any, and interest on the Securities in respect of which or for the benefit of which such money
has been collected, ratably, without preference or priority of any kind, according to the amounts
due and payable on such Securities for principal and any premium, if any, and interest,
respectively; and

     THIRD: The balance, if any, to the Company or any other Person or Persons entitled thereto.

     SECTION 507. Limitation on Suits.

     No Holder of any Security of any series shall have any right to institute any proceeding under
this Indenture, or for the appointment of a receiver or trustee, or for any other remedy under this
Indenture, unless:

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

          (2) the Holders of not less than 25% in principal amount of the Outstanding Securities of that
series make a written request to the Trustee to pursue the remedy;

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

          (4) the Trustee fails to comply with such request within 60 days after the Trustee receives
the notice, request and offer of indemnity and does not receive, during those 60 days, from Holders
of a majority in aggregate principal amount of Outstanding Securities of such series, a direction
inconsistent with such request.

However, the above limitations do not apply to a suit by a Holder to enforce (a) the payment of
amounts due on that Holder’s Securities after the applicable due date or (b) the right to convert
that Holder’s Securities in accordance with this Indenture.

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

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

-41-

 

     SECTION 509. Restoration of Rights and Remedies.

     If the Trustee or any Holder has instituted any proceeding to enforce any right or remedy
under this Indenture and such proceeding has been discontinued or abandoned for any reason, or has
been determined adversely to the Trustee or to such Holder, then and in every such case, subject to
any determination in such proceeding, the 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 510. Rights and Remedies Cumulative.

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

     SECTION 511. Delay or Omission Not Waiver.

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

     SECTION 512. Control by Holders.

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

          (1) such direction shall not be in conflict with any rule of law or with this Indenture and
the Trustee shall not have determined that the action so directed would be unjustly prejudicial to
Holders of Securities of that series, or any other series, not taking part in such direction; and

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

-42-

 

     SECTION 513. Waiver of Past Defaults.

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

          (1) in the payment of the principal of or any premium or interest on any Security of such
series or the payment of any redemption price, purchase price or repurchase price with respect to
any Security of such series,

          (2) arising from the Company’s failure to convert any Security in accordance with this
Indenture, or

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

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

     SECTION 514. Undertaking for Costs.

     In any suit for the enforcement of any right or remedy under this Indenture, or in any suit
against the Trustee for any action taken, suffered or omitted by it as Trustee, a court may require
any party litigant in such suit to file an undertaking to pay the costs of such suit, including
legal fees and expenses, and may assess costs against any such party litigant, in the manner and to
the extent provided in the Trust Indenture Act; provided that neither this Section
nor the Trust Indenture Act shall be deemed to authorize any court to require such an undertaking
or to make such an assessment in any suit instituted by the Company or in any suit for the
enforcement of the right to convert any Security in accordance with Article Fourteen or in any suit
instituted by the Trustee, to any suit instituted by any Holder or group of Holders for the
enforcement of the payment of the principal of, or any premium or interest on, any Security on or
after the due date for such payment.

     SECTION 515. Waiver of Usury, Stay or Extension Laws.

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

ARTICLE SIX

THE TRUSTEE

     SECTION 601. Certain Duties and Responsibilities.

     The duties and responsibilities of the Trustee shall be as provided by the Trust Indenture
Act. Notwithstanding the foregoing, no provision of this Indenture shall require the Trustee to
expend or risk its own funds or otherwise incur any financial liability in the performance of any
of its duties hereunder, or in the exercise of any of its rights or powers. Whether or not therein
expressly so provided, every provision of this Indenture relating to the conduct or affecting the
liability of or affording protection to the Trustee shall be subject to the provisions of this
Section. No provision of this Indenture shall be construed to relieve the Trustee from liability
for its own negligent action, its own negligent failure to act or its own willful misconduct,
subject to Section 603.

     SECTION 602. Notice of Defaults.

     If a Default or Event of Default has occurred and the Trustee has received notice of the
Default or Event of Default in accordance with the Indenture, the Trustee must mail to each Holder
a notice of the Default or Event of Default within 30 days after receipt of the notice. However,
the Trustee need not mail the notice if the Default or Event of Default (a) has been cured or
waived; or (b) is not in the payment of any amounts due with respect to any Security or the failure
to convert any Security in accordance with the Indenture and the Trustee in good faith determines
that withholding the notice is in the best interests of Holders. In addition, the Trustee shall
give the Holders of Securities of such series notice of such Default or Event of Default actually
known to it as and to the extent provided by the Trust Indenture Act.

     SECTION 603. Certain Rights of Trustee.

     Subject to the provisions of Section 601:

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

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

          (3) the Trustee may consult with counsel of its selection and the written 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;

          (4) 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 demand of any of the Holders pursuant to this

-44-

 

Indenture, unless such Holders shall have offered to the Trustee reasonable security or
indemnity that is reasonably satisfactory to the Trustee against the costs, expenses and
liabilities which might be incurred by it in compliance with such request or demand;

          (5) the Trustee shall not be bound to make any investigation into the facts or matters stated
in any resolution, certificate, statement, instrument, opinion, report, notice, request, direction,
consent, order, bond, debenture, note, other evidence of indebtedness or other paper or document,
but the Trustee, in its discretion, may make further inquiry or investigation into such facts or
matters as it may see fit;

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

          (7) the Trustee shall not be liable for any action taken, suffered, or omitted to be taken by
it in good faith and reasonably believed by it to be authorized or within the discretion or rights
or powers conferred upon it by this Indenture;

          (8) the Trustee shall not be deemed to have notice of any Default or Event of Default unless a
responsible officer of the Trustee has actual knowledge thereof or unless written notice of any
event which is in fact such a Default is received by the Trustee at the Corporate Trust Office of
the Trustee, and such notice references the Securities and this Indenture;

          (9) the permissive rights of the Trustee to do the things enumerated in this Indenture shall
not be construed as a duty unless so specified herein. The Trustee shall not be liable in
connection with the performance of its duties hereunder, except for its own negligence or willful
misconduct; and

          (10) whenever in the administration of the trusts imposed upon it by this Indenture the
Trustee shall deem it necessary or desirable that a matter be proved or established prior to taking
or suffering any action hereunder, such matter may be deemed to be conclusively proved and
established by an Officer’s Certificate, and such Officer’s Certificate shall be full warrant to
the Trustee for any action taken or suffered in good faith under the provisions of the Indenture in
reliance upon such Officer’s Certificate, but in its discretion the Trustee may, in lieu thereof,
accept other evidence of such matter or may request such additional evidence as it may deem
reasonable.

     SECTION 604. Not Responsible for Recitals or Issuance of Securities.

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

-45-

 

     SECTION 605. May Hold Securities and Act as Trustee Under Other Indentures.

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

     Subject to the limitations imposed by the Trust Indenture Act, nothing in this Indenture shall
prohibit the Trustee from becoming and acting as trustee under other indentures under which other
securities, or certificates of interest of participation in other securities, of the Company are
outstanding in the same manner as if it were not Trustee hereunder.

     SECTION 606. Money Held in Trust.

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

     SECTION 607. Compensation and Reimbursement.

     The Company agrees:

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

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

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

     When the Trustee incurs expenses or renders services in connection with an Event of Default
specified in Section 501(5) or Section 501(6), the expenses (including the reasonable charges and
expenses of its counsel) and the compensation for the services are intended to constitute expenses
of administration under any applicable Federal or State Bankruptcy, insolvency or other similar
law.

-46-

 

     SECTION 608. Conflicting Interests.

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

     SECTION 609. Corporate Trustee Required; Eligibility.

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

     SECTION 610. Resignation and Removal; Appointment of Successor.

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

     The Trustee may resign at any time with respect to the Securities of one or more series by
giving written notice thereof to the Company. If the instrument of acceptance by a successor
Trustee required by Section 611 shall not have been delivered to the Trustee within 30 days after
the giving of such notice of resignation, the resigning Trustee may petition, at the expense of the
Company, any court of competent jurisdiction for the appointment of a successor Trustee with
respect to the Securities of such series.

     The Trustee may be removed at any time with respect to the Securities of any series by Act of
the Holders of a majority in principal amount of the Outstanding Securities of such series,
delivered to the Trustee and to the Company. If the instrument of acceptance by a successor Trustee
required by Section 611 shall not have been delivered to the Trustee within 30 days after the
giving of such notice of removal, the Trustee being removed may petition, at the expense of the
Company, any court of competent jurisdiction for the appointment of a successor Trustee with
respect to the Securities of such series.

-47-

 

     If at any time:

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

          (2) the Trustee shall cease to be eligible under Section 609 and shall fail to resign after
written request therefor by the Company or by any such Holder, or

          (3) the Trustee shall become incapable of acting or shall be adjudged a bankrupt or insolvent
or a receiver of the Trustee or of its property shall be appointed or any public officer shall take
charge or control of the Trustee or of its property or affairs for the purpose of rehabilitation,
conservation or liquidation,

then, in any such case, (A) the Company by a Board Resolution may remove the Trustee with respect
to all Securities, or (B) subject to Section 514, any Holder who has been a bona fide Holder of a
Security for at least six months may, on behalf of himself and all others similarly situated,
petition any court of competent jurisdiction for the removal of the Trustee with respect to all
Securities and the appointment of a successor Trustee or Trustees.

     If the Trustee shall resign, be removed or become incapable of acting, or if a vacancy shall
occur in the office of Trustee for any cause, with respect to the Securities of one or more series,
the Company, by a Board Resolution, shall promptly appoint a successor Trustee or Trustees with
respect to the Securities of that or those series (it being understood that any such successor
Trustee may be appointed with respect to the Securities of one or more or all of such series and
that at any time there shall be only one Trustee with respect to the Securities of any particular
series) and shall comply with the applicable requirements of Section 611. If, within one year after
such resignation, removal or incapability, or the occurrence of such vacancy, a successor Trustee
with respect to the Securities of any series shall be appointed by Act of the Holders of a majority
in principal amount of the Outstanding Securities of such series delivered to the Company and the
retiring Trustee, the successor Trustee so appointed shall, forthwith upon its acceptance of such
appointment in accordance with the applicable requirements of Section 611, become the successor
Trustee with respect to the Securities of such series and to that extent supersede the successor
Trustee appointed by the Company. If no successor Trustee with respect to the Securities of any

bona fide Holder of a Security of such series for at least six months may, on behalf of himself and
all others similarly situated, petition any court of competent jurisdiction for the appointment of
a successor Trustee with respect to the Securities of such series.

     The Company shall give notice of each resignation and each removal of the Trustee with respect
to the Securities of any series and each appointment of a successor Trustee with respect to the

     SECTION 611. Acceptance of Appointment by Successor.

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

     In case of the appointment hereunder of a successor Trustee with respect to the Securities of
one or more (but not all) series, the Company, the retiring Trustee and each successor Trustee with
respect to the Securities of one or more series shall execute and deliver an indenture supplemental
hereto wherein each successor Trustee shall accept such appointment and which (1) shall contain
such provisions as shall be necessary or desirable to transfer and confirm to, and to vest in, each
successor Trustee all the rights, powers, trusts and duties of the retiring Trustee with respect to
the Securities of that or those series to which the appointment of such successor Trustee relates,
(2) if the retiring Trustee is not retiring with respect to all Securities, shall contain such
provisions as shall be deemed necessary or desirable to confirm that all the rights, powers, trusts
and duties of the retiring Trustee with respect to the Securities of that or those series as to
which the retiring Trustee is not retiring shall continue to be vested in the retiring Trustee, and
(3) shall add to or change any of the provisions of this Indenture as shall be necessary to provide
for or facilitate the administration of the trusts hereunder by more than one Trustee, it being
understood that nothing herein or in such supplemental indenture shall constitute such Trustees
co-trustees of the same trust and that each such Trustee shall be trustee of a trust or trusts
hereunder separate and apart from any trust or trusts hereunder administered by any other such
Trustee; and upon the execution and delivery of such supplemental indenture the resignation or
removal of the retiring Trustee shall become effective to the extent provided therein and each such
successor Trustee, without any further act, deed or conveyance, shall become vested with all the
rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of that or
those series to which the appointment of such successor Trustee relates; but, on request of the
Company or any successor Trustee, such retiring Trustee shall, upon payment in full of all of its
charges, duly assign, transfer and deliver to such successor Trustee all property and money held by
such retiring Trustee hereunder with respect to the Securities of that or those series to which the
appointment of such successor Trustee relates.

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

-49-

 

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

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

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

     SECTION 613. Preferential Collection of Claims Against Company.

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

     SECTION 614. Appointment of Authenticating Agent.

     The Trustee may appoint an Authenticating Agent or Agents with respect to one or more series
of Securities which shall be authorized to act on behalf of the Trustee to authenticate Securities
of such series issued upon original issue and upon exchange, registration of transfer or partial
redemption thereof or pursuant to Section 306, and Securities so authenticated shall be entitled to
the benefits of this Indenture and shall be valid and obligatory for all purposes as if
authenticated by the Trustee hereunder. Wherever reference is made in this Indenture to the
authentication and delivery of Securities by the Trustee or the Trustee’s certificate of
authentication, such reference shall be deemed to include authentication and delivery on behalf of
the Trustee by an Authenticating Agent and a certificate of authentication executed on behalf of
the Trustee by an Authenticating Agent. Each Authenticating Agent shall be acceptable to the
Company and shall at all times be a corporation organized and doing business under the laws of the
United States of America, any State thereof or the District of Columbia, authorized under such laws
to act as Authenticating Agent, having (or if the Authenticating Agent is a member of a bank
holding company system, its bank holding company has) a combined capital and surplus of not less
than $50,000,000 and subject to supervision or examination by Federal or State authority. If such
Authenticating Agent publishes reports of condition at least annually, pursuant to law or to the
requirements of said supervising or examining authority, then for the purposes of this Section, the
combined capital and surplus of such Authenticating Agent shall be deemed to be its combined
capital and surplus as set forth in its most recent report of condition so published. If at any
time an Authenticating Agent shall cease to be eligible in accordance with the provisions of this
Section,

-50-

 

such Authenticating Agent shall resign immediately in the manner and with the effect specified
in this Section.

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

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

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

     If an appointment with respect to one or more series is made pursuant to this Section 614, the
Securities of such series may have endorsed thereon, in addition to the Trustee’s certificate of
authentication, an alternative certificate of authentication in the following form:

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

     The Company covenants and agrees for the benefit of each series of Securities that it will
duly and punctually pay the principal of and any premium and interest on the Securities of that

Company will give prompt written notice to the Trustee of the location, and any change in the
location, of such office or agency. If at any time the Company shall fail to maintain any such
required office or agency or shall fail to furnish the Trustee with the address thereof, such
presentations, surrenders, notices and demands may be made or served at the 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.

-58-

 

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

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

     If the Company shall at any time act as its own Paying Agent with respect to any series of
Securities, it will, on or before each due date of the principal of or any premium or interest on
any of the Securities of that series, segregate and hold in trust for the benefit of the Persons
entitled thereto a sum sufficient to pay the principal and any premium and interest so becoming due
until such sums shall be paid to such Persons or otherwise disposed of as herein provided and will
promptly notify the Trustee of its action or failure so to act.

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

     The Company will cause each Paying Agent for any series of Securities other than the Trustee
to execute and deliver to the Trustee an instrument in which such Paying Agent shall agree with the
Trustee, subject to the provisions of this Section, that such Paying Agent will (1) hold all sums
held by it for the payment of the principal of (and premium, if any) or interest on Securities of
that series in trust for the benefit of the Persons entitled thereto until such sums shall be paid
to such Persons or otherwise disposed of as herein provided; (2) give the Trustee notice of any
default by the Company (or any other obligor upon the Securities of that series) in the making of
any payment of principal (and premium, if any) or interest on the Securities of that series; and
(3) at any time during the continuance of any such default, upon the written request of the
Trustee, forthwith pay to the Trustee all sums held in trust by such Paying Agent for payment in
respect of the Securities of that series.

     The Company may at any time, for the purpose of obtaining the satisfaction and discharge of

released from all further liability with respect to such money.

Business Days prior to the date such money would escheat to the State or two years after such
principal (and premium, if any) or interest has become due and payable shall be paid to the Company
on Company Request, or (if then held by the Company) shall be discharged from such trust; and the
Holder of such Security shall thereafter, as an unsecured general creditor, look only to the

ARTICLE ELEVEN

REDEMPTION OF SECURITIES

     SECTION 1101. Applicability of Article.

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

     SECTION 1102. Election to Redeem; Notice to Trustee.

     The election of the Company to redeem any Securities shall be evidenced by a Board Resolution
or in another manner specified as contemplated by Section 301 for such Securities. In case of any
redemption at the election of the Company of the Securities of any series (including any such
redemption affecting only a single Security), the Company shall, at least 40 days (or 45 days if
fewer than all the Securities of any series are to be redeemed) prior to the Redemption Date fixed
by the Company (unless a shorter notice shall be satisfactory to the Trustee), notify the Trustee
of such Redemption Date, of the principal amount of Securities of such series to be redeemed and,
if applicable, of the tenor of the Securities to be redeemed. In the case of any redemption of
Securities prior to the expiration of any restriction on such redemption provided in the terms of
such Securities or elsewhere in this Indenture, the Company shall furnish the Trustee with an
Officers’ Certificate evidencing compliance with such restriction.

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

     If fewer than all the Securities of any series are to be redeemed (unless all the Securities
of such series and of a specified tenor are to be redeemed or unless such redemption affects only a
single Security), the particular Securities to be redeemed shall be
selected not more than 40 days
prior to the Redemption Date by the Trustee, from the Outstanding Securities of such series not
previously called for redemption, by lot, or in the Trustee’s discretion, on a pro-rata basis or by
such other method as the Trustee may deem fair and appropriate, provided that the
unredeemed portion of the principal amount of any Security shall be in an authorized denomination
(which shall not be less than the minimum authorized denomination) for such Security. If fewer than
all the Securities of such series and of a specified tenor are to be redeemed (unless such
redemption affects only a single Security), the particular Securities to be redeemed shall be
selected not more than 40 days prior to the Redemption Date by the Trustee, from the Outstanding
Securities of such series and specified tenor not previously called for redemption in accordance
with the preceding sentence.

     If any Security selected for partial redemption is converted in part before termination of the
conversion right with respect to the portion of the Security so selected, the converted portion of
such Security shall be deemed (so far as may be), at the option of the Company, to be the portion
selected for redemption. Securities which have been converted during a selection of Securities to
be redeemed shall be treated by the Trustee as Outstanding for the purpose of such selection.

-61-

 

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

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

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

     SECTION 1104. Notice of Redemption.

     Notice of redemption shall be given by first-class mail, postage prepaid, mailed not fewer
than 30 nor more than 60 days prior to the Redemption Date, unless a shorter period is specified in
the Securities to be redeemed, to each Holder of Securities to be redeemed, at its address
appearing in the Security Register.

     Failure to give notice by mailing in the manner herein provided to the Holder of any
Registered Securities designated for redemption as a whole or in part, or any defect in the notice
of any such Holder, shall not affect the validity of the proceedings for the redemption of any
other Securities or portion thereof.

     Any notice that is mailed to the Holder of any Registered Securities in the manner herein
provided shall be conclusively presumed to have been duly given, whether or not such Holder
receives the notice.

     All notices of redemption shall identify the Securities to be redeemed (including CUSIP
number(s)) and shall state:

          (1) the Redemption Date,

          (2) the Redemption Price (including accrued interest, if any),

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

-62-

 

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

          (5) the place or places where each such Security is to be surrendered for payment of the
Redemption Price,

          (6) if applicable, the conversion price, that the date on which the right to convert the
principal of the Securities or the portions thereof to be redeemed will terminate will be the
Business Day prior to the Redemption Date and the place or places where such Securities may be
surrendered for conversion,

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

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

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

     SECTION 1105. Deposit of Redemption Price.

     On or prior to 11:00 a.m., New York time, on any Redemption Date, the Company shall deposit
with the Trustee or with a Paying Agent (or, if the Company is acting as its own Paying Agent,
segregate and hold in trust as provided in Section 1003) an amount of money sufficient to pay the
Redemption Price of, and (except if the Redemption Date shall be an Interest Payment Date) accrued
interest on, all the Securities which are to be redeemed on that date.

     If any Security called for redemption is converted, any money deposited with the Trustee or
with a Paying Agent or so segregated and held in trust for the redemption of such Security shall
(subject to the right of any Holder of such Security to receive interest as provided in the last
paragraph of Section 307) be paid to the Company on Company Request, or if then held by the
Company, shall be discharged from such trust.

     SECTION 1106. Securities Payable on Redemption Date.

     Notice of redemption having been given as aforesaid, the Securities so to be redeemed shall,
on the Redemption Date, become due and payable at the Redemption Price therein specified, and from
and after such date (unless the Company shall default in the payment of the Redemption Price and
accrued interest) such Securities shall cease to bear interest. Upon surrender of any such Security
for redemption in accordance with said notice, such Security shall be paid by the Company at the
Redemption Price, together with accrued interest to the Redemption Date; provided,
however,

-63-

 

that, unless otherwise specified as contemplated by Section 301, installments of interest
whose Stated Maturity is on or prior to the Redemption Date will be payable to the Holders of such
Securities, or one or more Predecessor Securities, registered as such at the close of business on
the relevant Record Dates according to their terms and the provisions of Section 307.

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

     SECTION 1107. Securities Redeemed in Part.

     Any Security which is to be redeemed only in part shall be surrendered at a Place of Payment
therefor (with, if the Company or the Trustee so requires, due endorsement by, or a written
instrument of transfer in form satisfactory to the Company and the Trustee duly executed by, the
Holder thereof or its attorney duly authorized in writing), and the Company shall execute, and the
Trustee shall authenticate and deliver to the Holder of such Security without service charge, a new
Security or Securities of the same series and of like tenor, of any authorized denomination as
requested by such Holder, in aggregate principal amount equal to and in exchange for the unredeemed
portion of the principal of the Security so surrendered. If a Security in global form is so
surrendered, the Company shall execute, and the Trustee shall authenticate and deliver to the U.S.
Depositary or other Depositary for such Security in global form as shall be specified in the
Company Order with respect thereto to the Trustee, without service charge, a new Security in global
form in denomination equal to and in exchange for the unredeemed portion of the principal of the
Security in global form so surrendered.

ARTICLE TWELVE

SINKING FUNDS

     SECTION 1201. Applicability of Article.

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

     The minimum amount of any sinking fund payment provided for by the terms of any Securities is
herein referred to as a “mandatory sinking fund payment,” and any payment in excess of such minimum
amount provided for by the terms of such Securities is herein referred to as an “optional sinking
fund payment.” If provided for by the terms of any Securities, the cash amount of any sinking fund
payment may be subject to reduction as provided in Section 1202. Each sinking fund payment shall be
applied to the redemption of Securities as provided for by the terms of such Securities.

-64-

 

     SECTION 1202. Satisfaction of Sinking Fund Payments with Securities.

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

     SECTION 1203. Redemption of Securities for Sinking Fund.

     Not fewer than 60 days prior to each sinking fund payment date for any Securities, the Company
will deliver to the Trustee an Officers’ Certificate specifying the amount of the next ensuing
sinking fund payment for such Securities pursuant to the terms of such Securities, the portion
thereof, if any, which is to be satisfied by payment of cash and the portion thereof, if any, which
is to be satisfied by delivering and crediting Securities pursuant to Section 1202 and will also
deliver to the Trustee any Securities to be so delivered. Not fewer than 30 days prior to each such
sinking fund payment date, the Trustee shall select the Securities to be redeemed upon such sinking
fund payment date in the manner specified in Section 1103 and cause notice of the redemption
thereof to be given in the name of and at the expense of the Company in the manner provided in
Section 1104. Such notice having been duly given, the redemption of such Securities shall be made
upon the terms and in the manner stated in Sections 1106 and 1107.

ARTICLE THIRTEEN

DEFEASANCE AND COVENANT DEFEASANCE

     SECTION 1301. Company’s Option to Effect Defeasance or Covenant Defeasance.

     The Company may elect, at its option at any time, to have Section 1302 or Section 1303 applied
to any Securities or any series of Securities, as the case may be, designated pursuant to Section
301 as being defeasible pursuant to such Section 1302 or 1303, in accordance with any applicable
requirements provided pursuant to Section 301 and upon compliance with the conditions set forth
below in this Article. Any such election shall be evidenced by a Board Resolution or in another
manner specified as contemplated by Section 301 for such Securities.

     SECTION 1302. Defeasance and Discharge.

     Upon the Company’s exercise of its option (if any) to have this Section applied to any
Securities or any series of Securities, as the case may be, the Company shall be deemed to have
been discharged from its obligations, and the provisions of Article Fifteen shall cease to be
effective, with

-65-

 

respect to such Securities as provided in this Section on and after the date the conditions
set forth in Section 1304 are satisfied (hereinafter called “Defeasance”). For this purpose, such
Defeasance means that the Company shall be deemed to have paid and discharged the entire
indebtedness represented by such Securities and to have satisfied all its other obligations under
such Securities and this Indenture insofar as such Securities are concerned (and the Trustee, at
the expense of the Company, shall execute proper instruments acknowledging the same), subject to
the following which shall survive until otherwise terminated or discharged hereunder: (1) the
rights of Holders of such Securities to receive, solely from the trust fund described in Section
1304 and as more fully set forth in such Section, payments in respect of the principal of and any
premium and interest on such Securities when payments are due, (2) the Company’s obligations with
respect to such Securities under Sections 304, 305, 306, 1002 and 1003, and, if applicable, Article
Fourteen, (3) the rights, powers, trusts, duties and immunities of the Trustee hereunder and (4)
this Article. Subject to compliance with this Article, the Company may exercise its option (if any)
to have this Section applied to any Securities notwithstanding the prior exercise of its option (if
any) to have Section 1303 applied to such Securities.

     SECTION 1303. Covenant Defeasance.

     Upon the Company’s exercise of its option (if any) to have this Section applied to any
Securities or any series of Securities, as the case may be, (1) the Company shall be released from
its obligations under Article 8, Sections 704 and 1006, inclusive, and any covenants provided
pursuant to Section 301(19), 901(2) or 901(7) and (2) the occurrence of any event specified in
Sections 501(4) (with respect to any of Article 8, Section 704 or Section 1006, inclusive, and any
such covenants provided pursuant to Section 301(19), 901(2) or 901(7)), shall be deemed not to be
or result in an Event of Default, and (3) the provisions of Article Fifteen (if applicable to such
series of Securities) shall cease to be effective, in each case with respect to such Securities as
provided in this Section on and after the date the conditions set forth in Section 1304 are
satisfied (hereinafter called “Covenant Defeasance”). For this purpose, such Covenant Defeasance
means that, with respect to such Securities, the Company may omit to comply with and shall have no
liability in respect of any term, condition or limitation set forth in any such specified Section
(to the extent so specified in the case of Section 501(4)) or Article Fifteen, whether directly or
indirectly by reason of any reference elsewhere herein to any such Section or Article or by reason
of any reference in any such Section or Article to any other provision herein or in any other
document, but the remainder of this Indenture and such Securities shall be unaffected thereby.

     SECTION 1304. Conditions to Defeasance or Covenant Defeasance.

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

          (1) The Company shall irrevocably have deposited or caused to be deposited with the Trustee
(or another trustee which satisfies the requirements contemplated by Section 609 and agrees to
comply with the provisions of this Article applicable to it) as trust funds in trust for the
purpose of making the following payments, specifically pledged as security for, and dedicated
solely to, the benefits of the Holders of such Securities, (A) money in an amount, or (B) U.S.
Government

-66-

 

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

          (2) In the event of an election to have Section 1302 apply to any Securities or any series of
Securities, as the case may be, the Company shall have delivered to the Trustee an Opinion of
Counsel stating that (A) the Company has received from, or there has been published by, the
Internal Revenue Service a ruling or (B) since the date of this instrument, there has been a change
in the applicable Federal income tax law, in either case (A) or (B) to the effect that, and based
thereon such opinion shall confirm that, the Holders of such Securities will not recognize gain or
loss for Federal income tax purposes as a result of the deposit, Defeasance and discharge to be
effected with respect to such Securities and will be subject to Federal income tax on the same
amount, in the same manner and at the same times as would be the case if such deposit, Defeasance
and discharge were not to occur.

          (3) In the event of an election to have Section 1303 apply to any Securities or any series of
Securities, as the case may be, the Company shall have delivered to the Trustee an Opinion of
Counsel to the effect that the Holders of such Securities will not recognize gain or loss for
Federal income tax purposes as a result of the deposit and Covenant Defeasance to be effected with
respect to such Securities and will be subject to Federal income tax on the same amount, in the
same manner and at the same times as would be the case if such deposit and Covenant Defeasance were
not to occur.

-67-

 

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

          (5) No event which is, or after notice or lapse of time or both would become, an Event of
Default with respect to such Securities or any other Securities shall have occurred and be
continuing at the time of such deposit or, with regard to any such event specified in Sections
501(5) and (6), at any time on or prior to the 90th day after the date of such deposit (it being
understood that this condition shall not be deemed satisfied until after such 90th day).

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

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

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

          (9) At the time of such deposit, (A) no default in the payment of any principal of or premium
or interest on any Senior Debt shall have occurred and be continuing, (B) no event of default with
respect to any Senior Debt shall have resulted in such Senior Debt becoming, and continuing to be,
due and payable prior to the date on which it would otherwise have become due and payable (unless
payment of such Senior Debt has been made or duly provided for), and (C) no other event of default
with respect to any Senior Debt shall have occurred and be continuing permitting (after notice or
lapse of time or both) the holders of such Senior Debt (or a trustee on behalf of such holders) to
declare such Senior Debt due and payable prior to the date on which it would otherwise have become
due and payable.

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

     SECTION 1305. Deposited Money and U.S. Government Obligations to be Held in Trust;
Miscellaneous Provisions.

     Subject to the provisions of the last paragraph of Section 1003, all money and U.S. Government
Obligations (including the proceeds thereof) deposited with the Trustee or other qualifying trustee
(solely for purposes of this Section and Section 1306, the Trustee and any such other trustee are
referred to collectively as the “Trustee”) pursuant to Section 1304 in respect of any Securities
shall be held in trust and applied by the Trustee, in accordance with the provisions of such

-68-

 

Securities and this Indenture, to the payment, either directly or through any such Paying
Agent (including the Company acting as its own Paying Agent) as the Trustee may determine, to the
Holders of such Securities, of all sums due and to become due thereon in respect of principal and
any premium and interest, but money so held in trust need not be segregated from other funds except
to the extent required by law. Money and U.S. Government Obligations so held in trust shall not be
subject to the provisions of Article Fifteen.

     The Company shall pay and indemnify the Trustee against any tax, fee or other charge imposed
on or assessed against the U.S. Government Obligations deposited pursuant to Section 1304 or the
principal and interest received in respect thereof other than any such tax, fee or other charge
which by law is for the account of the Holders of Outstanding Securities.

     Anything in this Article to the contrary notwithstanding, the Trustee shall deliver or pay to
the Company from time to time upon Company Request any money or U.S. Government Obligations held by
it as provided in Section 1304 with respect to any Securities which, in the opinion of a nationally
recognized firm of independent public accountants expressed in a written certification thereof
delivered to the Trustee, are in excess of the amount thereof which would then be required to be
deposited to effect the Defeasance or Covenant Defeasance, as the case may be, with respect to such
Securities.

     SECTION 1306. Reinstatement.

     If the Trustee or the Paying Agent is unable to apply any money in accordance with this
Article with respect to any Securities by reason of any order or judgment of any court or
governmental authority enjoining, restraining or otherwise prohibiting such application, then the
obligations under this Indenture and such Securities from which the Company has been discharged or
released pursuant to Section 1302 or 1303 shall be revived and reinstated as though no deposit had
occurred pursuant to this Article with respect to such Securities, until such time as the Trustee
or Paying Agent is permitted to apply all money held in trust pursuant to Section 1305 with respect
to such Securities in accordance with this Article; provided, however, that if the
Company makes any payment of principal of or any premium or interest on any such Security following
such reinstatement of its obligations, the Company shall be subrogated to the rights (if any) of
the Holders of such Securities to receive such payment from the money so held in trust.

ARTICLE FOURTEEN

CONVERSION AND EXCHANGE OF SECURITIES

     SECTION 1401. Applicability of Article.

     The provisions of this Article shall be applicable to the Securities of any series which are
convertible or exchangeable into shares of Common Stock of the Company, and the issuance of such
shares of Common Stock upon the conversion or exchange of such Securities, except as otherwise
specified as contemplated by Section 301 for the Securities of such series.

-69-

 

     SECTION 1402. Exercise of Conversion and Exchange Privilege.

     In order to exercise a conversion or exchange privilege, the Holder of a Security of a series
with such a privilege shall surrender such Security to the Company at the office or agency
maintained for that purpose pursuant to Section 1002, accompanied by a duly executed conversion or
exchange notice to the Company substantially in the form set forth in Section 206 stating that the
Holder elects to convert or exchange such Security or a specified portion thereof. Such notice
shall also state, if different from the name and address of such Holder, the name or names (with
address) in which the certificate or certificates for shares of Common Stock which shall be
issuable on such conversion or exchange shall be issued. Securities surrendered for conversion or
exchange shall (if so required by the Company or the Trustee) be duly endorsed by or accompanied by
instruments of transfer in forms satisfactory to the Company and the Trustee duly executed by the
registered Holder or its attorney duly authorized in writing; and Securities so surrendered for
conversion or exchange (in whole or in part) during the period from the close of business on any
Regular Record Date to the opening of business on the next succeeding Interest Payment Date
(excluding Securities or portions thereof called for redemption during the period beginning at the
close of business on a Regular Record Date and ending at the opening of business on the first
Business Day after the next succeeding Interest Payment Date, or if such Interest Payment Date is
not a Business Day, the second such Business Day) shall also be accompanied by payment in funds
acceptable to the Company of an amount equal to the interest payable on such Interest Payment Date
on the principal amount of such Security then being converted or exchanged, and such interest shall
be payable to such registered Holder notwithstanding the conversion or exchange of such Security,
subject to the provisions of Section 307 relating to the payment of Defaulted Interest by the
Company. As promptly as practicable after the receipt of such notice and of any payment required
pursuant to a Board Resolution and, subject to Section 303, set forth, or determined in the manner
provided, in an Officers’ Certificate, or established in one or more indentures supplemental hereto
setting forth the terms of such series of Security, and the surrender of such Security in
accordance with such reasonable regulations as the Company may prescribe, the Company shall issue
and shall deliver, at the office or agency at which such Security is surrendered, to such Holder or
on its written order, a certificate or certificates for the number of full shares of Common Stock
issuable upon the conversion or exchange of such Security (or specified portion thereof), in
accordance with the provisions of such Board Resolution, Officers’ Certificate or supplemental
indenture, and cash as provided therein in respect of any fractional share of such Common Stock
otherwise issuable upon such conversion or exchange. Such conversion or exchange shall be deemed to
have been effected immediately prior to the close of business on the date on which such notice and
such payment, if required, shall have been received in proper order for conversion or exchange by
the Company and such Security shall have been surrendered as aforesaid (unless such Holder shall
have so surrendered such Security and shall have instructed the Company to effect the conversion or
exchange on a particular date following such surrender and such Holder shall be entitled to convert
or exchange such Security on such date, in which case such conversion or exchange shall be deemed
to be effected immediately prior to the close of business on such date) and at such time the rights
of the Holder of such Security as such Security Holder shall cease and the person or persons in
whose name or names any certificate or certificates for shares of Common Stock of the Company shall
be issuable upon such conversion or exchange shall be deemed to have become the Holder or Holders

of record of the shares represented thereby. Except as set forth above and subject to the
final paragraph of Section 307, no payment or adjustment shall be made upon any conversion or
exchange on account of any interest accrued on the Securities (or any part thereof) surrendered for
conversion or exchange or on account of any dividends on the Common Stock of the Company issued
upon such conversion or exchange.

     In the case of any Security which is converted or exchanged in part only, upon such conversion
or exchange the Company shall execute and the Trustee shall authenticate and deliver to or on the
order of the Holder thereof, at the expense of the Company, a new Security or Securities of the
same series, of authorized denominations, in aggregate principal amount equal to the unconverted or
unexchanged portion of such Security.

     SECTION 1403. No Fractional Shares.

     No fractional share of Common Stock of the Company shall be issued upon conversions or
exchanges of Securities of any series. If more than one Security shall be surrendered for
conversion or exchange at one time by the same Holder, the number of full shares which shall be
issuable upon conversion or exchange shall be computed on the basis of the aggregate principal
amount of the Securities (or specified portions thereof to the extent permitted hereby) so
surrendered. If, except for the provisions of this Section 1403, any Holder of a Security or
Securities would be entitled to a fractional share of Common Stock of the Company upon the
conversion or exchange of such Security or Securities, or specified portions thereof, the Company
shall pay to such Holder an amount in cash equal to the current market value of such fractional
share computed (unless otherwise specified with respect to any series of Securities), (i) if such
Common Stock is listed or admitted to unlisted trading privileges on a national securities exchange
or market, on the basis of the last reported sale price regular way on such exchange or market on
the last trading day prior to the date of conversion or exchange upon which such a sale shall have
been effected, or (ii) if such Common Stock is not at the time so listed or admitted to unlisted
trading privileges on a national securities exchange or market, on the basis of the average of the
bid and asked prices of such Common Stock in the over-the-counter market, on the last trading day
prior to the date of conversion or exchange, as reported by the National Quotation Bureau,
Incorporated or similar organization if the National Quotation Bureau, Incorporated is no longer
reporting such information, or if not so available, the fair market price as determined by the
Board of Directors. For purposes of this Section, “trading day” shall mean each Monday, Tuesday,
Wednesday, Thursday and Friday other than any day on which the Common Stock is not traded on the
New York Stock Exchange, or if the Common Stock is not traded on the New York Stock Exchange, on
the principal exchange or market on which the Common Stock is traded or quoted.

     SECTION 1404. Adjustment of Conversion and Exchange Price.

     The conversion or exchange price of Securities of any series that is convertible or
exchangeable into Common Stock of the Company shall be adjusted for any stock dividends, stock
splits, reclassifications, combinations or similar transactions in accordance with the terms of the
supplemental indenture or Board Resolutions setting forth the terms of the Securities of such
series.

-71-

 

     Whenever the conversion or exchange price is adjusted, the Company shall compute the adjusted
conversion or exchange price in accordance with terms of the applicable Board Resolution or
supplemental indenture and shall prepare an Officers’ Certificate setting forth the adjusted
conversion or exchange price and showing in reasonable detail the facts upon which such adjustment
is based, and such certificate shall forthwith be filed at each office or agency maintained for the
purpose of conversion or exchange of Securities pursuant to Section 1002 and, if different, with
the Trustee. The Company shall forthwith cause a notice setting forth the adjusted conversion or
exchange price to be mailed, first class postage prepaid, to each Holder of Securities of such
series at its address appearing on the Security Register and to any conversion or exchange agent
other than the Trustee.

     SECTION 1405. Notice of Certain Corporate Actions.

     In case:

          (1) the Company shall declare a dividend (or any other distribution) on its Common Stock
payable otherwise than in cash out of its retained earnings (other than a dividend for which
approval of any shareholders of the Company is required) that would require an adjustment pursuant
to Section 1404; or

          (2) the Company shall authorize the granting to all or substantially all of the holders of its
Common Stock of rights, options or warrants to subscribe for or purchase any shares of capital
stock of any class or of any other rights (other than any such grant for which approval of any
shareholders of the Company is required); or

          (3) of any reclassification of the Common Stock of the Company (other than a subdivision or
combination of its outstanding shares of Common Stock, or of any consolidation, merger or share
exchange to which the Company is a party and for which approval of any shareholders of the Company
is required), or of the sale of all or substantially all of the assets of the Company; or

          (4) of the voluntary or involuntary dissolution, liquidation or winding up of the Company;
then the Company shall cause to be filed with the Trustee, and shall cause to be mailed to all
Holders at their last addresses as they shall appear in the Security Register, at least 20 days (or
10 days in any case specified in Clause (1) or (2) above) prior to the applicable record date
hereinafter specified, a notice stating (i) the date on which a record is to be taken for the
purpose of such dividend, distribution, rights, options or warrants, or, if a record is not to be
taken, the date as of which the holders of Common Stock of record to be entitled to such dividend,
distribution, rights, options or warrants are to be determined, or (ii) the date on which such
reclassification, consolidation, merger, share exchange, sale, dissolution, liquidation or winding
up is expected to become effective, and the date as of which it is expected that holders of Common
Stock of record shall be entitled to exchange their shares of Common Stock for securities, cash or
other property deliverable upon such reclassification, consolidation, merger, share exchange, sale,
dissolution, liquidation or winding up. If at any time the Trustee shall not be the conversion or
exchange agent, a copy of such notice shall also forthwith be filed by the Company with the
Trustee.

-72-

 

     SECTION 1406. Reservation of Shares of Common Stock.

     The Company shall at all times reserve and keep available, free from preemptive rights, out of
its authorized but unissued Common Stock, for the purpose of effecting the conversion or exchange
of Securities, the full number of shares of Common Stock of the Company then issuable upon the
conversion or exchange of all outstanding Securities of any series that has conversion or exchange
rights.

     SECTION 1407. Payment of Certain Taxes Upon Conversion and Exchange.

     Except as provided in the next sentence, the Company will pay any and all taxes that may be
payable in respect of the issue or delivery of shares of its Common Stock on conversion or exchange
of Securities pursuant hereto. The Company shall not, however, be required to pay any tax which may
be payable in respect of any transfer involved in the issue and delivery of shares of its Common
Stock in a name other than that of the Holder of the Security or Securities to be converted or
exchanged, and no such issue or delivery shall be made unless and until the person requesting such
issue has paid to the Company the amount of any such tax, or has established, to the satisfaction
of the Company, that such tax has been paid.

     SECTION 1408. Nonassessability.

     The Company covenants that all shares of its Common Stock which may be issued upon conversion
or exchange of Securities will upon issue in accordance with the terms hereof be duly and validly
issued and fully paid and nonassessable.

     SECTION 1409. Provision in Case of Consolidation, Merger or Sale of Assets.

     In case of any consolidation or merger of the Company with or into any other Person, any
merger of another Person with or into the Company (other than a merger which does not result in any
reclassification, conversion, exchange or cancellation of outstanding shares of Common Stock of the
Company) or any conveyance, sale, transfer or lease of all or substantially all of the assets of
the Company, the Person formed by such consolidation or resulting from such merger or which
acquires such assets, as the case may be, shall execute and deliver to the Trustee a supplemental
indenture providing that the Holder of each Security of a series then Outstanding that is
convertible or exchangeable into Common Stock of the Company shall have the right thereafter (which
right shall be the exclusive conversion or exchange right thereafter available to said Holder),
during the period such Security shall be convertible or exchangeable, to convert or exchange such
Security only into the kind and amount of securities, cash and other property receivable upon such
consolidation, merger, conveyance, sale, transfer or lease by a holder of the number of shares of
Common Stock of the Company into which such Security might have been converted or exchanged
immediately prior to such consolidation, merger, conveyance, sale, transfer or lease, assuming such
holder of Common Stock of the Company (i) is not a Person with which the Company consolidated or
merged with or into or which merged into or with the Company or to which such conveyance, sale,
transfer or lease was made, as the case may be (a “Constituent Person”), or an Affiliate of a
Constituent Person and (ii) failed to exercise his rights of election, if any, as to the kind or
amount of securities, cash and

-73-

 

other property receivable upon such consolidation, merger, conveyance, sale, transfer or lease
(provided that if the kind or amount of securities, cash and other property
receivable upon such consolidation, merger, conveyance, sale, transfer, or lease is not the same
for each share of Common Stock of the Company held immediately prior to such consolidation, merger,
conveyance, sale, transfer or lease by others than a Constituent Person or an Affiliate thereof and
in respect of which such rights of election shall not have been exercised (“Non-electing Share”),
then for the purpose of this Section 1409 the kind and amount of securities, cash and other
property receivable upon such consolidation, merger, conveyance, sale, transfer or lease by the
holders of each Non-electing Share shall be deemed to be the kind and amount so receivable per
share by a plurality of the Non-electing Shares). Such supplemental indenture shall provide for
adjustments which, for events subsequent to the effective date of such supplemental indenture,
shall be as nearly equivalent as may be practicable to the adjustments provided for in this Article
or in accordance with the terms of the supplemental indenture or Board Resolutions setting forth
the terms of such adjustments. The above provisions of this Section 1409 shall similarly apply to
successive consolidations, mergers, conveyances, sales, transfers or leases. Notice of the
execution of such a supplemental indenture shall be given by the Company to the Holder of each
Security of a series that is convertible or exchangeable into Common Stock of the Company as
provided in Section 106 promptly upon such execution.

     Neither the Trustee nor any conversion or exchange agent, if any, shall be under any
responsibility to determine the correctness of any provisions contained in any such supplemental
indenture relating either to the kind or amount of shares of stock or other securities or property
or cash receivable by Holders of Securities of a series convertible or exchangeable into Common
Stock of the Company upon the conversion or exchange of their Securities after any such
consolidation, merger, conveyance, transfer, sale or lease or to any such adjustment, but may
accept as conclusive evidence of the correctness of any such provisions, and shall be protected in
relying upon, an Opinion of Counsel with respect thereto, which the Company shall cause to be
furnished to the Trustee upon request.

     SECTION 1410. Duties of Trustee Regarding Conversion and Exchange.

     Neither the Trustee nor any conversion or exchange agent shall at any time be under any duty
or responsibility to any Holder of Securities of any series that is convertible or exchangeable
into Common Stock of the Company to determine whether any facts exist which may require any
adjustment of the conversion or exchange price, or with respect to the nature or extent of any such
adjustment when made, or with respect to the method employed, whether herein or in any supplemental
indenture (or whether any provisions of any supplemental indenture are correct), any resolutions of
the Board of Directors or written instrument executed by one or more officers of the Company
provided to be employed in making the same. Neither the Trustee nor any conversion or exchange
agent shall be accountable with respect to the validity or value (or the kind or amount) of any
shares of Common Stock of the Company, or of any securities or property, which may at any time be
issued or delivered upon the conversion or exchange of any Securities and neither the Trustee nor
any conversion or exchange agent makes any representation with respect thereto. Subject to the
provisions of Section 601, neither the Trustee nor any conversion or exchange agent shall be
responsible for any failure of the Company to issue, transfer or deliver any shares of its Common

-74-

 

Stock or stock certificates or other securities or property upon the surrender of any Security
for the purpose of conversion or exchange or to comply with any of the covenants of the Company
contained in this Article Fourteen or in the applicable supplemental indenture, resolutions of the
Board of Directors or written instrument executed by one or more duly authorized officers of the
Company.

     SECTION 1411. Repayment of Certain Funds Upon Conversion and Exchange.

     Any funds which at any time shall have been deposited by the Company or on its behalf with the
Trustee or any other paying agent for the purpose of paying the principal of, and premium, if any,
and interest, if any, on any of the Securities (including, but not limited to, funds deposited for
the sinking fund referred to in Article Twelve hereof and funds deposited pursuant to Article
Thirteen hereof) and which shall not be required for such purposes because of the conversion or
exchange of such Securities as provided in this Article Fourteen shall after such conversion or
exchange be repaid to the Company by the Trustee upon the Company’s written request.

ARTICLE FIFTEEN

SUBORDINATION OF SECURITIES

     SECTION 1501. Applicability of Article; Securities Subordinate to Senior Debt.

     The provisions of this Article shall be applicable to the Securities of any series which
expressly provide that such Securities shall be subordinated to Senior Debt and that this Article
Fifteen is applicable to such series of Securities, except as otherwise specified as contemplated
by Section 301 for the Securities of such series.

     The Company covenants and agrees, and each Holder of a Security, by his acceptance thereof,
likewise covenants and agrees, that, to the extent and in the manner hereinafter set forth in this
Article Fifteen, the indebtedness represented by the Securities and the payment of the principal of
and premium, if any, and interest on each and all of the Securities are hereby expressly made
subordinate and subject in right of payment to the prior payment in full of all Senior Debt. Senior
Debt shall continue to be Senior Debt and entitled to the benefits of these subordination
provisions regardless of any amendment, modification or waiver of any term of Senior Debt or
extension or renewal of Senior Debt.

     SECTION 1502. Payment Over of Proceeds Upon Dissolution, Etc.

     Upon any distribution of assets of the Company in the event of:

     (a) any insolvency or bankruptcy case or proceeding, or any receivership, liquidation,
reorganization or other similar case or proceeding in connection therewith, relative to the Company
or to its creditors, as such, or to its assets, or

     (b) any liquidation, dissolution or other winding up of the Company, whether voluntary or
involuntary and whether or not involving insolvency or bankruptcy, or

-75-

 

     (c) any assignment for the benefit of creditors or any other marshaling of assets and
liabilities of the Company,

then and in any such event the holders of Senior Debt shall be entitled to receive:

          (1) payment in full of all amounts due or to become due on or in respect of all Senior Debt,
or provision shall be made for such payment in money or money’s worth, before the Holders of the
Securities are entitled to receive any payment on account of principal, premium, if any, and
interest on the Securities, and

          (2) any payment or distribution of any kind or character, whether in cash, property or
securities, which may be payable or deliverable in respect of the Securities in any such case,
proceeding, dissolution, liquidation or other winding up or event, including any such payment or
distribution which may be payable or deliverable by reason of the payment of any other indebtedness
of the Company being subordinated to the payment of the Securities.

     In the event that, notwithstanding the foregoing provisions of this Section 1502, the Trustee
or the Holder of any Security shall have received any payment or distribution of assets of the
Company of any kind or character, whether in cash, property or securities, including any such
payment or distribution which may be payable or deliverable by reason of the payment of any other
indebtedness of the Company being subordinated to the payment of the Securities, before all Senior
Debt is paid in full or payment thereof provided for, and if such fact shall, at or prior to the
time of such payment or distribution, have been made known to the Trustee or, as the case may be,
such Holder, then in such event such payment or distribution shall be paid over or delivered
forthwith to the trustee in bankruptcy, receiver, liquidating trustee, custodian, assignee, agent
or other Person making payment or distribution of assets of the Company for application to the
payment of all Senior Debt remaining unpaid, to the extent necessary to pay all Senior Debt in
full, after giving effect to any concurrent payment or distribution to or for the holders of Senior
Debt.

     The consolidation of the Company with, or the merger of the Company into, another person or
the liquidation or dissolution of the Company following the conveyance or transfer of its
properties and assets substantially as an entirety to another person upon the terms and conditions
set forth in Article Eight shall not be deemed a dissolution, winding up, liquidation,
reorganization, assignment for the benefit of creditors or marshalling of assets and liabilities of
the Company for the purposes of this Section 1502 if the Person formed by such consolidation or
into which the Company is merged or the Person which acquires by conveyance or transfer such
properties and assets substantially as an entirety, as the case may be, shall as part of such
consolidation, merger, conveyance or transfer, comply with the conditions set forth in Article
Eight.

     SECTION 1503. Payment Permitted If No Default.

     Nothing contained in this Article Fifteen or elsewhere in this Indenture or in any of the
Securities shall prevent (a) the Company, at any time except during the pendency of any case,
proceeding, dissolution, liquidation or other winding up, assignment for the benefit of creditors
or other marshalling of assets and liabilities of the Company referred to in Section 1502, from
making

-76-

 

payments at any time of principal amount, premium, if any or interest, as the case may be, in
respect of the Securities, or (b) the application by the Trustee of any money deposited with it
hereunder to payment of or on account of the principal, premium, if any, or interest, as the case
may be, in respect of the Securities or the retention of such payment by the Holders of the
Securities, if, at the time of such application by the Trustee, the Trustee did not have actual
knowledge that such payment would have been prohibited by the provisions of this Article Fifteen.

     SECTION 1504. Subrogation to Rights of Holders of Senior Debt.

     Subject to the payment in full of all Senior Debt, the Holders of the Securities shall be
subrogated to the extent of the payments or distributions made to holders of such Senior Debt
pursuant to the provisions of this Article Fifteen (equally and ratably with the holders of all
indebtedness of the Company which by its express terms is subordinated to 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 such Senior Debt to receive payments or
distributions of cash, property and securities applicable to the Senior Debt until the principal,
premium, if any, or interest on the Securities shall be paid in full. For purposes of such
subrogation, no payments or distributions to the holders of the Senior Debt 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 Fifteen, and no payments over pursuant to the provisions of this
Article Fifteen to the holders of Senior Debt by Holders of the Securities or the Trustee, shall,
as among the Company, its creditors other than holders of Senior Debt and the Holders of the
Securities, be deemed to be a payment or distribution by the Company to or on account of the Senior
Debt.

     SECTION 1505. Provisions Solely to Define Relative Right.

     The provisions of this Article Fifteen are and are intended solely for the purpose of defining
the relative rights of the Holders of the Securities, on the one hand, and the holders of Senior
Debt, on the other hand. Nothing contained in this Article Fifteen or elsewhere in this Indenture
or in the Securities is intended to or shall (a) impair, as among the Company, its creditors other
than holders of Senior Debt and the Holders of the Securities, the obligation of the Company, which
is absolute and unconditional (and which, subject to the rights under this Article Fifteen of the
holders of Senior Debt, is intended to rank equally with all other general obligations of the
Company), to pay to the Holders of the Securities the principal, premium, if any, or interest on
the Securities as and when the same shall become due and payable in accordance with their terms; or
(b) affect the relative rights against the Company of the Holders of the Securities and creditors
of the

     Company other than the holders of Senior Debt; or (c) 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 Fifteen of the holders of Senior Debt
to receive cash, property and securities otherwise payable or deliverable to the Trustee or such
Holder.

-77-

 

     SECTION 1506. Trustee to Effectuate Subordination.

     Each Holder of a Security by its acceptance thereof authorizes and directs the Trustee on his
behalf to take such action as may be necessary or appropriate to effectuate the subordination
provided in this Article Fifteen and appoints the Trustee its attorney-in-fact for any and all such
purposes.

     SECTION 1507. No Waiver of Subordination Provisions.

     No right of any present or future holder of any Senior Debt 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
non-compliance by the Company with the terms, provisions and covenants of this Indenture,
regardless of any knowledge thereof any such holder may have or be otherwise charged with.

     Without in any way limiting the generality of the foregoing paragraph, the holders of Senior
Debt may, with the consent or agreement of the Company, to the extent required by the instrument or
instruments governing such Senior Debt, at any time and from time to time, without the consent of
or notice to the Trustee or the Holders of the Securities, without incurring responsibility to the
Holders of the Securities and without impairing or releasing the subordination provided in this
Article Fifteen or the obligations hereunder of the Holders of the Securities to the holders of
Senior Debt, do any one or more of the following: (i) change the manner, place or terms of payment
or extend the time of payment of, or renew or alter, Senior Debt, or otherwise amend or supplement
in any manner Senior Debt or any instrument evidencing the same or any agreement under which Senior
Debt is outstanding; (ii) sell, exchange, release or otherwise deal with any property pledged,
mortgaged or otherwise securing Senior Debt; (iii) release any Person liable in any manner for the
collection of Senior Debt; and (iv) exercise or refrain from exercising any rights against the
Company and any other Person.

     SECTION 1508. Reliance on Judicial Order or Certificate of Liquidating Agent.

     Upon any payment or distribution of assets of the Company referred to in this Article Fifteen,
the Trustee and the Holders of the Securities shall be entitled to rely upon any order or decree
entered by any court of competent jurisdiction in which such insolvency, bankruptcy, receivership,
liquidation, reorganization, dissolution, winding up or similar case or proceeding is pending, or a
certificate of the Trustee in bankruptcy, liquidating trustee, custodian, receiver, assignee for
the benefit of creditors, agent or other Person making such payment or distribution, delivered to
the Trustee or to the Holders of Securities, for the purpose of ascertaining the Persons entitled
to participate in such payment or distribution, the holders of the Senior Debt and other
indebtedness of the Company, the amount thereof or payable thereon, the amount or amounts paid or
distributed thereon and all other facts pertinent thereto or to this Article Fifteen.

-78-

 

     SECTION 1509. Trustee Not Fiduciary for Holders of Senior Debt.

     The Trustee shall not be deemed to owe any fiduciary duty to the holders of Senior Debt and
shall not be liable to any such holders if it shall in good faith mistakenly pay over or distribute
to Holders of Securities or to the Company or to any other Person cash, property or securities to
which any holders of Senior Debt shall be entitled by virtue of this Article Fifteen or otherwise.
The Trustee shall not be charged with knowledge of the existence of Senior Debt or of any facts
that would prohibit any payment hereunder or that would permit the resumption of any such payment
unless the Trustee shall have received actual notice to that effect. With respect to the holders of
Senior Debt, the Trustee undertakes to perform or to observe only such of its covenants or
obligations as are specifically set forth in this Article Fifteen and no implied covenants or
obligations with respect to holders of Senior Debt shall be read into this Indenture against the
Trustee.

     SECTION 1510. Rights of Trustee as Holders of Senior Debt; Preservation of Trustee’s Rights.

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

     Nothing in this Article Fifteen shall apply to claims of, or payments to, the Trustee under or
pursuant to Section 607.

     SECTION 1511. Article Fifteen Applicable to Paying Agents.

     In case 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 in such case
(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 Fifteen in addition to or in place of the Trustee; provided,
however, that Section 1509 and 1511 shall not apply to the Company or any Affiliate of the
Company if it or such Affiliate acts as Paying Agent.

     SECTION 1512. Certain Conversions Not Deemed Payment.

     For the purposes of this Article Fifteen only, (1) the issuance and delivery of junior
securities upon conversion of Securities in accordance with Article Fifteen shall not be deemed to
constitute a payment or distribution on account of the principal of, premium, if any, or interest
on Securities or on account of the purchase or other acquisition of Securities, and (2) the
payment, issuance or delivery of cash (except in satisfaction of fractional shares pursuant to
Section 1403), property or securities (other than junior securities) upon conversion of a Security
shall be deemed to constitute payment on account of the principal of, premium, if any, or interest
on such Security. For the purposes of this Section 1512, the term “junior securities” means (a)
shares of any stock of any class

-79-

 

of the Company or (b) securities of the Company that are subordinated in right of payment to
all Senior Debt that may be outstanding at the time of issuance or delivery of such securities to
substantially the same extent as, or to a greater extent than, the Securities are so subordinated
as provided in this Article Fifteen. Nothing contained in this Article Fifteen or elsewhere in this
Indenture or in the Securities is intended to or shall impair, as among the Company, its creditors
(other than holders of Senior Debt) and the Holders, the right, which is absolute and
unconditional, of the Holder of any Security to convert such Security in accordance with this
Article Fifteen.
