Company may deliver Securities of any series executed by the Company to the Trustee for

delivery of such Securities have been complied with.

          (d) The Trustee shall have the right to decline to authenticate and deliver the Securities
under this Section 3.03 if the issue of the Securities pursuant to this Indenture will

or otherwise in a manner which is not reasonably acceptable to the Trustee.

          (e) Each Security shall be dated the date of its authentication, except as otherwise provided
pursuant to Section 3.01 with respect to the Securities of such series.

          (f) Notwithstanding the provisions of Section 3.01 and of this Section 3.03, if all of the

shall represent an aggregate amount equal to the aggregate principal amount of the Outstanding
Securities of such series to be represented by such Global Securities, (ii) shall be registered, if
in registered form, in the name of the Depositary for such Global Security or Securities or the
nominee of such Depositary, (iii) shall be delivered by the Trustee to such Depositary or pursuant

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

The aggregate principal amount of each Global Security may from time to time be increased or
decreased by adjustments made on the records of the Security Custodian, as provided in this
Indenture.

          (h) Each Depositary designated pursuant to Section 3.01 for a Global Security in registered
form must, at the time of its designation and at all times while it serves as such Depositary, be a
clearing agency registered under the Exchange Act and any other applicable statute or regulation.

          (i) Members of, or participants in, the Depositary (“Members”) shall have no rights under this
Indenture with respect to any Global Security held on their behalf by the Depositary or by the
Security Custodian under such Global Security, and the Depositary may be treated by the Company,
the Trustee, the Paying Agent and the Registrar and any of their agents as the absolute owner of
such Global Security for all purposes whatsoever. Notwithstanding the foregoing, nothing herein
shall prevent the Company, the Trustee, the Paying Agent or the Registrar or any of their agents
from giving effect to any written certification, proxy or other authorization furnished by the
Depositary or impair, as between the Depositary and any owner of a beneficial interest in any
Global Security, the operation of customary practices of the Depositary governing the exercise of
the rights of the Depositary (or its nominee) as Holder of such Global Security. The Holder of a
Global Security may grant proxies and otherwise

16

 

authorize any Person, including Members and Persons that may hold interests through Members,
to take any action that a Holder is entitled to take under this Indenture or the Securities. None
of the Trustee, the Paying Agent or the Security Registrar shall have any responsibility or
obligation to any beneficial owner in a Global Security, a Member or other Person with respect to
the accuracy of the records of the Depositary or its nominee or of any Member, with respect to any
ownership interest in the Securities or with respect to the delivery to any Member, beneficial
owner or other Person (other than the Depositary) of any notice (including any notice of
redemption) or the payment of any amount, under or with respect to such Securities. All notices
and communications to be given to the Securityholders and all payments to be made to
Securityholders under the Securities and this Indenture shall be given or made only to or upon the
order of the registered holders (which shall be the Depositary or its nominee in the case of the
Global Security). The rights of beneficial owners in the Global Security shall be exercised only
through the Depositary subject to the applicable procedures. The Trustee, the Paying Agent and the
Security Registrar shall be entitled to rely and shall be fully protected in relying upon
information furnished by the Depositary with respect to its members, participants and any
beneficial owners. The Trustee, the Paying Agent and the Security Registrar shall be entitled to
deal with the Depositary, and any nominee thereof, that is the registered holder of any Global
Security for all purposes of this Indenture relating to such Global Security (including the payment
of principal, premium, if any, and interest and additional amounts, if any, and the giving of
instructions or directions by or to the owner or holder of a beneficial ownership interest in such
Global Security) as the sole holder of such Global Security and shall have no obligations to the
beneficial owners thereof. None of the Trustee, the Paying Agent or the Security Registrar shall
have any responsibility or liability for any acts or omissions of the Depositary with respect to
such Global Security, for the records of any such depositary, including records in respect of
beneficial ownership interests in respect of any such Global Security, for any transactions between
the Depositary and any Member or between or among the Depositary, any such Member and/or any holder
or owner of a beneficial interest in such Global Security, or for any transfers of beneficial
interests in any such Global Security.

          (j) 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 one of the forms provided for herein duly executed by the Trustee or by an
Authenticating Agent by manual or facsimile signature of an
authorized signatory of the Trustee, and such
certificate upon any Security shall be conclusive evidence, and the only evidence, that such
Security has been duly authenticated and delivered hereunder and is entitled to the benefits of
this Indenture.

     Section 3.04 Temporary Securities.

          (a) 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 that are
printed, lithographed, typewritten, mimeographed or otherwise reproduced, in any authorized
denomination, substantially of the tenor of the definitive Securities in lieu of which they are
issued, in registered form and with such appropriate insertions, omissions, substitutions and other
variations as the officers executing such Securities may determine, as conclusively evidenced by
their execution of such Securities. Any such temporary Security may be in global form,
representing all or a portion of the Outstanding Securities of

17

 

such series. Every such temporary Security shall be executed by the Company and shall be
authenticated and delivered by the Trustee upon the same conditions and in substantially the same
manner, and with the same effect, as the definitive Security or Securities in lieu of which it is
issued.

          (b) If temporary Securities of any series are issued, the Company will cause definitive
Securities of such series to be prepared without unreasonable delay. After the preparation of
definitive Securities of such series, the temporary Securities of such series shall be exchangeable
for definitive Securities of such series upon surrender of such temporary Securities at the office
or agency of the Company in a Place of Payment for such series, without charge to the Holder. Upon
surrender for cancellation of any one or more temporary Securities of any series, the Company shall
execute and the Trustee shall authenticate and deliver in exchange therefor a like principal amount
of definitive Securities of the same series of authorized denominations and of like tenor. 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.

          (c) Upon any exchange of a portion of a temporary Global Security for a definitive Global
Security or for the individual Securities represented thereby pursuant to this Section 3.04 or
Section 3.06, the temporary Global Security shall be endorsed by the Trustee to reflect the
reduction of the principal amount evidenced thereby, whereupon the principal amount of such
temporary Global Security shall be reduced for all purposes by the amount so exchanged and
endorsed.

     Section 3.05 Registrar and Paying Agent.

          (a) The Company will keep, at an office or agency to be maintained by it in a Place of Payment
where Securities may be presented for registration or presented and surrendered for registration of
transfer or of exchange, and where Securities of any series that are convertible or exchangeable
may be surrendered for conversion or exchange, as applicable (the “Registrar”), a security register
for the registration and the registration of transfer or of exchange of the Securities (the
registers 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 “Register”), as in this Indenture
provided, which Register shall at all reasonable times be open for inspection by the Trustee. Such
Register shall be in written form or in any other form capable of being converted into written form
within a reasonable time. The Company may have one or more co-Registrars; the term “Registrar”
includes any co-registrar.

          (b) The Company shall enter into an appropriate agency agreement with any Registrar or
co-Registrar not a party to this Indenture. The agreement shall implement the provisions of this
Indenture that relate to such agent. The Company shall notify the Trustee of the name and address
of each such agent. If the Company fails to maintain a Registrar, the Trustee shall act as such
and shall be entitled to appropriate compensation therefor pursuant to Section 11.01. The Company
or any Affiliate thereof may act as Registrar, co-Registrar or transfer agent.

18

 

          (c) The Company hereby appoints the Trustee at its Corporate Trust Office as Registrar in
connection with the Securities and this Indenture, until such time as another Person is appointed
as such.

     Section 3.06 Transfer and Exchange.

          (a) Transfer.

     (i) Upon surrender for registration of transfer of any Security of any series at the
Registrar the Company shall execute, and the Trustee or any Authenticating Agent shall
authenticate and deliver, in the name of the designated transferee, one or more new
Securities of the same series for like aggregate principal amount of any authorized
denomination or denominations. The transfer of any Security shall not be valid as against
the Company or the Trustee unless registered at the Registrar by the Holder, or by his, her
or its attorney duly authorized in writing.

     (ii) Notwithstanding any other provision of this Section, unless and until it is
exchanged in whole or in part for the individual Securities represented thereby, a Global
Security representing all or a portion of the Securities of a series may not be transferred
except as a whole by the Depositary for such series to a nominee of such Depositary or by a
nominee of such Depositary to such Depositary or another nominee of such Depositary or by
such Depositary or any such nominee to a successor Depositary for such series or a nominee
of such successor Depositary.

          (b) Exchange.

     (i) At the option of the Holder, Securities of any series (other than a Global
Security, except as set forth below) may be exchanged for other Securities of the same
series for like aggregate principal amount of any authorized denomination or denominations,
upon surrender of the Securities to be exchanged at the Registrar.

     (ii) Whenever any Securities are so surrendered for exchange, the Company shall
execute, and the Trustee shall authenticate and deliver, the Securities that the Holder
making the exchange is entitled to receive.

          (c) Exchange of Global Securities for Individual Securities. Except as provided below, owners
of beneficial interests in Global Securities will not be entitled to receive individual Securities.

     (i) Individual Securities shall be issued to all owners of beneficial interests in a
Global Security in exchange for such interests if: (A) at any time the Depositary for the
Securities of a series notifies the Company that it is unwilling or unable to continue as
Depositary for the Securities of such series or if at any time the Depositary for the
Securities of such series shall no longer be eligible under Section 3.03(h) and, in each
case, a successor Depositary is not appointed by the Company within 90 days of such notice,
or (B) the Company executes and delivers to the Trustee and the Registrar an Officer’s
Certificate stating that such Global Security shall be so exchangeable.

19

 

     In connection with the exchange of an entire Global Security for individual
Securities pursuant to this subsection (c), such Global Security shall be deemed to
be surrendered to the Trustee for cancellation, and the Company shall execute, and
the Trustee, upon receipt of a Company Order for the authentication and delivery of
individual Securities of such series, will authenticate and deliver to each
beneficial owner identified by the Depositary in exchange for its beneficial
interest in such Global Security, an equal aggregate principal amount of individual
Securities of authorized denominations.

     (ii) The owner of a beneficial interest in a Global Security will be entitled to
receive an individual Security in exchange for such interest if an Event of Default has
occurred and is continuing. Upon receipt by the Security Custodian and Registrar of
instructions from the Holder of a Global Security directing the Security Custodian and
Registrar to (x) issue one or more individual Securities in the amounts specified to the
owner of a beneficial interest in such Global Security and (y) debit or cause to be debited
an equivalent amount of beneficial interest in such Global Security, subject to the rules
and regulations of the Depositary:

     (A) the Security Custodian and Registrar shall notify the Company and the
Trustee of such instructions, identifying the owner and amount of such beneficial
interest in such Global Security;

     (B) the Company shall promptly execute and the Trustee, upon receipt of a
Company Order for the authentication and delivery of individual Securities of such
series, shall authenticate and deliver to such beneficial owner individual
Securities in an equivalent amount to such beneficial interest in such Global
Security; and

     (C) the Security Custodian and Registrar shall decrease such Global Security by
such amount in accordance with the foregoing. In the event that the individual
Securities are not issued to each such beneficial owner promptly after the Registrar
has received a request from the Holder of a Global Security to issue such individual
Securities, the Company expressly acknowledges, with respect to the right of any
Holder to pursue a remedy pursuant to Section 7.07 hereof, the right of any
beneficial Holder of Securities to pursue such remedy with respect to the portion of
the Global Security that represents such beneficial Holder’s Securities as if such
individual Securities had been issued.

     (iii) If specified by the Company pursuant to Section 3.01 with respect to a series of
Securities, the Depositary for such series of Securities may surrender a Global Security for
such series of Securities in exchange in whole or in part for individual Securities of such
series on such terms as are acceptable to the Company and such Depositary. Thereupon, the
Company shall execute, and the Trustee shall authenticate and deliver, without service
charge,

     (A) to each Person specified by such Depositary a new individual Security or
Securities of the same series, of any authorized

20

 

denomination as requested by such Person in aggregate principal amount equal to
and in exchange for such Person’s beneficial interest in the Global Security; and

     (B) to such Depositary a new Global Security in a denomination equal to the
difference, if any, between the principal amount of the surrendered Global Security
and the aggregate principal amount of individual Securities delivered to Holders
thereof.

     (iv) In any exchange provided for in clauses (i) through (iii), the Company will
execute and the Trustee will authenticate and deliver individual Securities in registered
form in authorized denominations.

     (v) Upon the exchange in full of a Global Security for individual Securities, such
Global Security shall be canceled by the Trustee. Individual Securities issued in exchange
for a Global Security pursuant to this Section shall be registered in such names and in such
authorized denominations as the Depositary for such Global Security, pursuant to
instructions from its direct or indirect participants or otherwise, shall instruct the
Trustee. The Trustee shall deliver such Securities to the Persons in whose names such
Securities are so registered.

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

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

          (f) No service charge will be made for any registration of transfer or exchange of Securities.
The Company may require payment of a sum sufficient to cover any tax, assessment or other
governmental charge that may be imposed in connection with any registration of transfer or exchange
of Securities, other than those expressly provided in this Indenture to be made at the Company’s
own expense or without expense or charge to the Holders.

          (g) The Company shall not be required to (i) register, transfer or exchange Securities of any
series during a period beginning at the opening of business 15 days before the day of the
transmission of a notice of redemption of Securities of such series selected for redemption under
Section 4.03 and ending at the close of business on the day of such transmission, or (ii) register,
transfer or exchange any Security so selected for redemption in whole or in part, except the
unredeemed portion of any Security being redeemed in part.

          (h) Prior to the due presentation for registration of transfer or exchange of any Security,
the Company, the Trustee, the Paying Agent, the Registrar or any co-Registrar may deem and treat
the Person in whose name a Security is registered as the absolute owner of such Security (whether
or not such Security shall be overdue and notwithstanding any notation of

21

 

ownership or other writing thereon) for all purposes whatsoever, and none of the Company, the
Trustee, the Paying Agent, the Registrar or any co-Registrar shall be affected by any notice to the
contrary.

          (i) In case a successor Company (“Successor Company”) has executed an indenture supplemental
hereto with the Trustee pursuant to Article XIV, any of the Securities authenticated or delivered
pursuant to such transaction may, from time to time, at the request of the Successor Company, be
exchanged for other Securities executed in the name of the Successor Company with such changes in
phraseology and form as may be appropriate, but otherwise identical to the Securities surrendered
for such exchange and of like principal amount; and the Trustee, upon Company Order of the
Successor Company, shall authenticate and deliver Securities as specified in such order for the
purpose of such exchange. If Securities shall at any time be authenticated and delivered in any
new name of a Successor Company pursuant to this Section 3.06 in exchange or substitution for or
upon registration of transfer of any Securities, such Successor Company, at the option of the
Holders but without expense to them, shall provide for the exchange of all Securities at the time
Outstanding for Securities authenticated and delivered in such new name.

          (j) Each Holder of a Security agrees to indemnify the Company and the Trustee against any
liability that may result from the transfer, exchange or assignment of such Holder’s Security in
violation of any provision of this Indenture and/or applicable United States federal or state
securities laws.

          (k) The Trustee shall have no obligation or duty to monitor, determine or inquire as to
compliance with any restrictions on transfer imposed under this Indenture or under applicable law
with respect to any transfer of any interest in any Security other than to require delivery of such
certificates and other documentation or evidence as are expressly required by, and to do so if and
when expressly required by the terms of, this Indenture, and to examine the same to determine
substantial compliance as to form with the express requirements hereof.

          (l) Neither the Trustee nor any agent of the Trustee shall have any responsibility for any
actions taken or not taken by the Depositary.

     Section 3.07 Mutilated, Destroyed, Lost and Stolen Securities.

          (a) If (i) any mutilated Security is surrendered to the Trustee at its Corporate Trust Office
or (ii) the Company and the Trustee receive evidence to their satisfaction of the destruction, loss
or theft of any Security, and there is delivered to the Company and the Trustee security or
indemnity satisfactory to them to save each of them and any Paying Agent harmless, and neither the
Company nor a Responsible Officer of the Trustee receives notice that such Security has been
acquired by a protected purchaser, then the Company shall execute and upon Company Order the
Trustee shall authenticate and deliver, in exchange for or in lieu of any such mutilated,
destroyed, lost or stolen Security, a new Security of the same series and of like tenor, form,
terms and principal amount, bearing a number not contemporaneously outstanding, that neither gain
nor loss in interest shall result from such exchange or substitution.

22

 

          (b) 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
the amount due on such Security in accordance with its terms.

          (c) 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
respect thereto and any other expenses (including the fees and expenses of the Trustee) connected
therewith.

          (d) Every new Security of any series issued pursuant to this Section 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.

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

     Section 3.08 Payment of Interest; Interest Rights Preserved.

          (a) Interest on any Security that is payable and is punctually paid or duly provided for on
any Interest Payment Date shall be paid to the Person in whose name such Security (or one or more
Predecessor Securities) is registered at the close of business on the Record Date for such interest
notwithstanding the cancellation of such Security upon any transfer or exchange subsequent to the
Record Date. Payment of interest on Securities shall be made at the Corporate Trust Office (except
as otherwise specified pursuant to Section 3.01) or, at the option of the Company, by check mailed
to the address of the Person entitled thereto as such address shall appear in the Register or, if
provided pursuant to Section 3.01 and in accordance with arrangements satisfactory to the Trustee,
at the option of the Holder by wire transfer to an account designated by the Holder.

          (b) Any interest on any Security that 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 Record Date by virtue of his, her or its having been such a
Holder, and such Defaulted Interest may be paid by the Company, at its election in each case, as
provided in clause (i) or (ii) below:

     (i) The Company may elect to make payment of any Defaulted Interest to the Persons in
whose names such Securities (or their respective Predecessor Securities) are registered at
the close of business on a special record date for the payment of such Defaulted Interest (a
“Special Record Date”), which shall be fixed in the following manner. The Company shall
notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on
each such Security and the date of the proposed payment, and at the same time the Company
shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to
be paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the
Trustee for such deposit prior to

23

 

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 calendar days and not less than 10 calendar days
prior to the date of the proposed payment and not less than 10 calendar days after the
receipt by the Trustee of the notice of the proposed payment. The Trustee shall promptly
notify the Company of such Special Record Date and, in the name and at the expense of the
Company, shall cause notice of the proposed payment of such Defaulted Interest and the
Special Record Date therefor to be mailed, first-class postage prepaid, to the Holders of
such Securities at their addresses as they appear in the Register, not less than 10 calendar
days prior to such Special Record Date. Notice of the proposed payment of such Defaulted
Interest and the Special Record Date therefor having been mailed as aforesaid, such
Defaulted Interest shall be paid to the Persons in whose names such Securities (or their
respective Predecessor Securities) are registered at the close of business on such Special
Record Date and shall no longer be payable pursuant to the following clause (ii).

     (ii) The Company may make payment of any Defaulted Interest on Securities 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.

          (c) Subject to the provisions set forth herein relating to Record Dates, each Security
delivered pursuant to any provision of this Indenture in exchange or substitution for, or upon
registration of transfer of, any other Security shall carry all the rights to interest accrued and
unpaid, and to accrue, which were carried by such other Security.

     Section 3.09 Cancellation. Unless otherwise specified pursuant to Section 3.01 for Securities of any series, all Securities
surrendered for payment, redemption, registration of transfer or exchange or credit against any
sinking fund or otherwise shall, if surrendered to any Person other than the Trustee, be delivered
to the Trustee for cancellation and shall be promptly canceled by it and, if surrendered to the
Trustee, 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 that the Company may
have acquired in any manner whatsoever, 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. The Trustee
shall dispose of all canceled Securities held by it in accordance with its then customary
procedures and deliver a certificate of such disposal to the Company. The acquisition of any
Securities by the Company shall not operate as a redemption or satisfaction of the Indebtedness
represented thereby unless and until such Securities are surrendered to the Trustee for
cancellation.

     Section 3.10 Computation of Interest. Except as otherwise specified pursuant to Section 3.01 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.

24

 

     Section 3.11 Currency of Payments in Respect of Securities.

          (a) Except as otherwise specified pursuant to Section 3.01 for Securities of any series,
payment of the principal of and premium, if any, and interest on Securities of such series will be
made in U.S. Dollars.

          (b) For purposes of any provision of the Indenture where the Holders of Outstanding Securities
may perform an action that requires that a specified percentage of the Outstanding Securities of
all series perform such action and for purposes of any decision or determination by the Trustee of
amounts due and unpaid for the principal of and premium, if any, and interest on the Securities of
all series in respect of which moneys are to be disbursed ratably, the principal of and premium, if
any, and interest on the Outstanding Securities denominated in a Foreign Currency will be the
amount in U.S. Dollars based upon exchange rates, determined as specified pursuant to Section 3.01
for Securities of such series, as of the date for determining whether the Holders entitled to
perform such action have performed it or as of the date of such decision or determination by the
Trustee, as the case may be.

          (c) Any decision or determination to be made regarding exchange rates shall be made by an
agent appointed by the Company; provided, that such agent shall accept such appointment in writing
and the terms of such appointment shall, in the opinion of the Company at the time of such
appointment, require such agent to make such determination by a method consistent with the method
provided pursuant to Section 3.01 for the making of such decision or determination. All decisions
and determinations of such agent regarding exchange rates shall be in its sole discretion and
shall, in the absence of manifest error, be conclusive for all purposes and irrevocably binding
upon the Company, the Trustee and all Holders of the Securities.

     Section 3.12 Judgments. The Company may provide pursuant to Section 3.01 for Securities of any series that (a) the
obligation, if any, of the Company to pay the principal of, premium, if any, and interest on the
Securities of any series in a Foreign Currency or U.S. Dollars (the “Designated Currency”) as may
be specified pursuant to Section 3.01 is of the essence and agrees that, to the fullest extent
possible under applicable law, judgments in respect of such Securities shall be given in the
Designated Currency; (b) the obligation of the Company to make payments in the Designated Currency
of the principal of and premium, if any, and interest on such Securities shall, notwithstanding any
payment in any other Currency (whether pursuant to a judgment or otherwise), be discharged only to
the extent of the amount in the Designated Currency that the Holder receiving such payment may, in
accordance with normal banking procedures, purchase with the sum paid in such other Currency (after
any premium and cost of exchange) on the business day in the country of issue of the Designated
Currency or in the international banking community (in the case of a composite currency)
immediately following the day on which such Holder receives such payment; (c) if the amount in the
Designated Currency that may be so purchased for any reason falls short of the amount originally
due, the Company shall pay such additional amounts as may be necessary to compensate for such
shortfall; and (d) any obligation of the Company not discharged by such payment shall be due as a
separate and independent obligation and, until discharged as provided herein, shall continue in
full force and effect.

25

 

     Section 3.13 CUSIP Numbers. The Company in issuing any Securities may use CUSIP, ISIN or other similar numbers, if then
generally in use, and thereafter with respect to such series, the Trustee may use such numbers in
any notice of redemption or exchange with respect to such series 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 in writing of any change in the CUSIP, ISIN or other similar numbers.

ARTICLE IV

REDEMPTION OF SECURITIES

     Section 4.01 Applicability of Right of Redemption. Redemption of Securities (other than pursuant to a sinking fund, amortization or analogous
provision) permitted by the terms of any series of Securities shall be made in accordance with such
terms (except as otherwise specified pursuant to Section 3.01 for Securities of any series) in
accordance with this Article; provided, however, that if any such terms of a series of Securities
shall conflict with any provision of this Article, the terms of such series shall govern.

     Section 4.02 Selection of Securities to be Redeemed.

          (a) If the Company shall at any time elect to redeem all or any portion of the Securities of a
series then Outstanding, it shall at least 30 days prior to the Redemption Date fixed by the
Company (unless a shorter period shall be satisfactory to the Trustee) notify the Trustee of such
Redemption Date and of the principal amount of Securities to be redeemed, and thereupon the Trustee
shall select, by lot or in such other manner as the Trustee shall deem appropriate and fair and
which may provide for the selection for redemption of a portion of the principal amount of any
Security of such series; provided that the unredeemed portion of the principal amount of any
Security shall be in an authorized denomination (which shall not be less than the minimum
authorized denomination) for such Security. In any case where more than one Security of such
series is registered in the same name, the Trustee in its discretion may treat the aggregate
principal amount so registered as if it were represented by one Security of such series. The
Trustee shall, as soon as practicable, notify the Company in writing of the Securities and portions
of Securities so selected.

          (b) For all purposes of this Indenture, unless the context otherwise requires, all provisions
relating to the redemption of Securities shall relate, in the case of any Security redeemed or to
be redeemed only in part, to the portion of the principal amount of such Security that has been or
is to be redeemed. If the Company shall so direct, Securities registered in the name of the
Company, any Affiliate or any Subsidiary thereof shall not be included in the Securities selected
for redemption.

26

 

     Section 4.03 Notice of Redemption.

          (a) Notice of redemption 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, not less than 30 nor more than 60 days prior
to the Redemption Date, to the Holders of Securities of any series to be redeemed in whole or in
part pursuant to this Article, in the manner provided in Section 16.04. Any notice so given shall
be conclusively presumed to have been duly given, whether or not the Holder receives such notice.
Failure to give such notice, or any defect in such notice to the Holder of any Security of a series
designated for redemption, in whole or in part, shall not affect the sufficiency of any notice of
redemption with respect to the Holder of any other Security of such series.

          (b) All notices of redemption shall identify the Securities to be redeemed (including CUSIP,
ISIN or similar numbers, if available) and shall state:

     (i) such election by the Company to redeem Securities of such series pursuant to
provisions contained in this Indenture or the terms of the Securities of such series or a
supplemental indenture establishing such series, if such be the case;

     (ii) the Redemption Date;

     (iii) the Redemption Price;

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

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

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

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

     Section 4.04 Deposit of Redemption Price. On or prior to 11:00 a.m., New York City time, on the Redemption Date for any Securities, 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 6.03) an amount of money in
the Currency in which such Securities are denominated (except as provided pursuant to Section 3.01)
sufficient to pay the Redemption Price of such Securities or any portions thereof that are to be
redeemed on that date.

     Section 4.05 Securities Payable on Redemption Date. Notice of redemption having been given as aforesaid, any Securities so to be redeemed shall, on
the Redemption Date, become due and payable at the Redemption Price and from and after such date
(unless the Company shall Default in the payment of the Redemption Price) such Securities shall
cease to bear interest. Upon surrender of any such Security for redemption in accordance with said
notice, such

27

 

Security shall be paid by the Company at the Redemption Price; provided, however, that (unless
otherwise provided pursuant to Section 3.01) installments of interest that have a Stated Maturity
on or prior to the Redemption Date for such Securities shall be payable according to the terms of
such Securities and the provisions of Section 3.08.

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

     Section 4.06 Securities Redeemed in Part. Any Security that is to be redeemed only in part shall be surrendered at the Corporate Trust
Office or such other office or agency of the Company as is specified pursuant to Section 3.01 with,
if the Company, the Registrar or the Trustee so requires, due endorsement by, or a written
instrument of transfer in form satisfactory to the Company, the Registrar and the Trustee duly
executed by the Holder thereof or his, her 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, of like tenor and
form, 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; except that if a Global Security is so surrendered, the Company shall execute, and the
Trustee shall authenticate and deliver to the Depositary for such Global Security, without service
charge, a new Global Security in a denomination equal to and in exchange for the unredeemed portion
of the principal of the Global Security so surrendered. In the case of a Security providing
appropriate space for such notation, at the option of the Holder thereof, the Trustee, in lieu of
delivering a new Security or Securities as aforesaid, may make a notation on such Security of the
payment of the redeemed portion thereof.

ARTICLE V

SINKING FUNDS

     Section 5.01 Applicability of Sinking Fund.

          (a) Redemption of Securities permitted or required pursuant to a sinking fund for the
retirement of Securities of a series by the terms of such series of Securities shall be made in
accordance with such terms of such series of Securities and this Article, except as otherwise
specified pursuant to Section 3.01 for Securities of such series, provided, however, that if any
such terms of a series of Securities shall conflict with any provision of this Article, the terms
of such series shall govern.

          (b) The minimum amount of any sinking fund payment provided for by the terms of Securities of
any series is herein referred to as a “Mandatory Sinking Fund Payment,” and any payment in excess
of such minimum amount provided for by the terms of Securities of any series is herein referred to
as an “Optional Sinking Fund Payment.” If provided for by the terms of Securities of any series,
the cash amount of any Mandatory Sinking Fund Payment may be subject to reduction as provided in
Section 5.02.

28

 

     Section 5.02 Mandatory Sinking Fund Obligation. The Company may, at its option, satisfy any Mandatory Sinking Fund Payment obligation, in whole
or in part, with respect to a particular series of Securities by (a) delivering to the Trustee
Securities of such series in transferable form theretofore purchased or otherwise acquired by the
Company or redeemed at the election of the Company pursuant to Section 4.03 or (b) receiving credit
for Securities of such series (not previously so credited) acquired by the Company and theretofore
delivered to the Trustee. The Trustee shall credit such Mandatory Sinking Fund Payment obligation
with an amount equal to the Redemption Price specified in such Securities for redemption through
operation of the sinking fund and the amount of such Mandatory Sinking Fund Payment shall be
reduced accordingly. If the Company shall elect to so satisfy any Mandatory Sinking Fund Payment
obligation, it shall deliver to the Trustee not less than 45 days prior to the relevant sinking
fund payment date a written notice signed on behalf of the Company by its Chairman of the Board of
Directors, its President, one of its Vice Presidents, its Treasurer or one of its Assistant
Treasurers, which shall designate the Securities (and portions thereof, if any) so delivered or
credited and which shall be accompanied by such Securities (to the extent not theretofore
delivered) in transferable form. In case of the failure of the Company, at or before the time so
required, to give such notice and deliver such Securities the Mandatory Sinking Fund Payment
obligation shall be paid entirely in moneys.

     Section 5.03 Optional Redemption at Sinking Fund Redemption Price. In addition to the sinking fund requirements of Section 5.02, to the extent, if any, provided
for by the terms of a particular series of Securities, the Company may, at its option, make an
Optional Sinking Fund Payment with respect to such Securities. Unless otherwise provided by such
terms, (a) to the extent that the right of the Company to make such Optional Sinking Fund Payment
shall not be exercised in any year, it shall not be cumulative or carried forward to any subsequent
year, and (b) such optional payment shall operate to reduce the amount of any Mandatory Sinking
Fund Payment obligation as to Securities of the same series. If the Company intends to exercise
its right to make such optional payment in any year it shall deliver to the Trustee not less than
45 days prior to the relevant sinking fund payment date a certificate signed by its Chairman of the
Board of Directors, its President, one of its Vice Presidents, its Treasurer or one of its
Assistant Treasurers stating that the Company will exercise such optional right, and specifying the
amount which the Company will pay on or before the next succeeding sinking fund payment date. Such
certificate shall also state that no Event of Default has occurred and is continuing.

     Section 5.04 Application of Sinking Fund Payment.

          (a) If the sinking fund payment or payments made in funds pursuant to either Section 5.02 or
5.03 with respect to a particular series of Securities plus any unused balance of any preceding
sinking fund payments made in funds with respect to such series shall exceed $50,000 (or a lesser
sum if the Company shall so request, or such equivalent sum for Securities denominated other than
in U.S. Dollars), it shall be applied by the Trustee on the sinking fund payment date next
following the date of such payment, unless the date of such payment shall be a sinking fund payment
date, in which case such payment shall be applied on such sinking fund payment date, to the
redemption of Securities of such series at the redemption price specified pursuant to Section
4.03(b). The Trustee shall select, in the manner provided in Section 4.02, for redemption on such
sinking fund payment date, a sufficient principal amount of Securities of such series to absorb
said funds, as nearly as may be, and shall, at the expense and in the name of

29

 

the Company, thereupon cause notice of redemption of the Securities to be given in
substantially the manner provided in Section 4.03(a) for the redemption of Securities in part at
the option of the Company, except that the notice of redemption shall also state that the
Securities are being redeemed for the sinking fund. Any sinking fund moneys not so applied by the
Trustee to the redemption of Securities of such series shall be added to the next sinking fund
payment received in funds by the Trustee and, together with such payment, shall be applied in
accordance with the provisions of this Section 5.04. Any and all sinking fund moneys held by the
Trustee on the last sinking fund payment date with respect to Securities of such series, and not
held for the payment or redemption of particular Securities of such series, shall be applied by the
Trustee to the payment of the principal of the Securities of such series at Maturity.

          (b) On or prior to each sinking fund payment date, the Company shall pay to the Trustee a sum
equal to all interest accrued to but not including the date fixed for redemption on Securities to
be redeemed on such sinking fund payment date pursuant to this Section 5.04.

          (c) The Trustee shall not redeem any Securities of a series with sinking fund moneys or mail
any notice of redemption of Securities of such series by operation of the sinking fund during the
continuance of a Default in payment of interest on any Securities of such series or of any Event of
Default (other than an Event of Default occurring as a consequence of this paragraph) of which the
Trustee has actual knowledge, except that if the notice of redemption of any Securities of such
series shall theretofore have been mailed in accordance with the provisions hereof, the Trustee
shall redeem such Securities if funds sufficient for that purpose shall be deposited with the
Trustee in accordance with the terms of this Article. Except as aforesaid, any moneys in the
sinking fund at the time any such Default or Event of Default shall occur and any moneys thereafter
paid into the sinking fund shall, during the continuance of such Default or Event of Default, be
held as security for the payment of all the Securities of such series; provided, however, that in
case such Default or Event of Default shall have been cured or waived as provided herein, such
moneys shall thereafter be applied on the next sinking fund payment date on which such moneys are
required to be applied pursuant to the provisions of this Section 5.04.

ARTICLE VI

PARTICULAR COVENANTS OF THE COMPANY

     The Company hereby covenants and agrees as follows:

     Section 6.01 Payments of Securities. The Company will duly and punctually pay the principal of and premium, if any, on each series of
Securities, and the interest which shall have accrued thereon, at the dates and place and in the
manner provided in the Securities and in this Indenture.

     Section 6.02 Paying Agent.

          (a) The Company will maintain in each Place of Payment for any series of Securities, if any,
an office or agency where Securities may be presented or surrendered for payment, where Securities
of such series may be surrendered for registration of transfer or

30

 

exchange and where notices and demands to or upon the Company in respect of the Securities and
this Indenture may be served (the “Paying Agent”). The 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 Paying Agent to receive all presentations, surrenders, notices and demands.

          (b) The Company may also from time to time designate different or additional offices or
agencies where the Securities of any series may be presented or surrendered for any or all such
purposes (in or outside of such Place of Payment), and may from time to time rescind any such
designations; provided, however, that no such designation or rescission shall in any manner relieve
the Company of its obligations described in the preceding paragraph. The Company will give prompt
written notice to the Trustee of any such additional designation or rescission of designation and
of any change in the location of any such different or additional office or agency. The Company
shall enter into an appropriate agency agreement with any Paying Agent not a party to this
Indenture. The agreement shall implement the provisions of this Indenture that relate to such
agent. The Company shall notify the Trustee of the name and address of each such agent. The
Company or any Affiliate thereof may act as Paying Agent.

     Section 6.03 To Hold Payment in Trust.

          (a) If the Company or an Affiliate thereof shall at any time act as Paying Agent with respect
to any series of Securities, then, on or before the date on which the principal of and premium, if
any, or interest on any of the Securities of that series by their terms or as a result of the
calling thereof for redemption shall become payable, the Company or such Affiliate will segregate
and hold in trust for the benefit of the Holders of such Securities or the Trustee a sum sufficient
to pay such principal and premium, if any, or interest which shall have so become payable until
such sums shall be paid to such Holders or otherwise disposed of as herein provided, and will
notify the Trustee of its action or failure to act in that regard. Upon any proceeding under any
federal bankruptcy laws with respect to the Company or any Affiliate thereof, if the Company or
such Affiliate is then acting as Paying Agent, the Trustee shall replace the Company or such
Affiliate as Paying Agent.

          (b) If the Company shall appoint, and at the time have, a Paying Agent for the payment of the
principal of and premium, if any, or interest on any series of Securities, then prior to 11:00
a.m., New York City time, on the date on which the principal of and premium, if any, or interest on
any of the Securities of that series shall become payable as aforesaid, whether by their terms or
as a result of the calling thereof for redemption, the Company will deposit with such Paying Agent
a sum sufficient to pay such principal and premium, if any, or interest, such sum to be held in
trust for the benefit of the Holders of such Securities or the Trustee, and (unless such Paying
Agent is the Trustee), the Company or any other obligor of such Securities will promptly notify the
Trustee of its payment or failure to make such payment.

          (c) If the Paying Agent shall be other than the Trustee, the Company will cause such Paying
Agent to execute and deliver to the Trustee an instrument in which such

31

 

Paying Agent shall agree with the Trustee, subject to the provisions of this Section 6.03,
that such Paying Agent shall:

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

     (ii) give to 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 the principal of and premium,
if any, or interest on the Securities of that series; and

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

          (d) Anything in this Section 6.03 to the contrary notwithstanding, the Company may at any
time, for the purpose of obtaining a release, satisfaction or discharge of this Indenture or for
any other reason, pay or cause to be paid to the Trustee all sums held in trust by the Company or
by any Paying Agent other than the Trustee as required by this Section 6.03, such sums to be held
by the Trustee upon the same trusts as those upon which such sums were held by the Company or such
Paying Agent.

          (e) Any money deposited with the Trustee or any Paying Agent, or then held by the Company, in
trust for the payment of the principal of and premium, if any, or interest on any Security of any
series and remaining unclaimed for two years after such principal and premium, if any, or interest
has become due and payable shall be paid to the Company upon Company Order along with any interest
that has accumulated thereon as a result of such money being invested at the direction of the
Company, 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 Company for
payment of such amounts without interest thereon, and all liability of the Trustee or such Paying
Agent with respect to such trust money, and all liability of the Company as trustee thereof, shall
thereupon cease; provided, however, that the Trustee or such Paying Agent before being required to
make any such repayment, may at the expense of the Company cause to be published once, in a
newspaper published in the English language, customarily published on each Business Day and of
general circulation in The City of New York, notice that such money remains unclaimed and that,
after a date specified therein, which shall not be less than 30 days from the date of such
publication, any unclaimed balance of such money then remaining will be repaid to the Company.

     Section 6.04 Merger, Consolidation and Sale of Assets. Except as otherwise provided as contemplated by Section 3.01 with respect to any series of
Securities:

          (a) The Company will not consolidate with any other entity or accept a merger of any other
entity into the Company or permit the Company to be merged into any other entity, or sell other
than for cash or lease all or substantially all its assets to another entity, or purchase all or
substantially all the assets of another entity, unless (i) either the Company shall

32

 

be the continuing entity, or the successor, transferee or lessee entity (if other than the
Company) shall expressly assume, by indenture supplemental hereto, executed and delivered by such
entity prior to or simultaneously with such consolidation, merger, sale or lease, the due and
punctual payment of the principal of and interest and premium, if any, on all the Securities,
according to their tenor, and the due and punctual performance and observance of all other
obligations to the Holders and the Trustee under this Indenture or under the Securities to be
performed or observed by the Company; (ii) immediately after such consolidation, merger, sale,
lease or purchase the Company or the successor, transferee or lessee entity (if other than the
Company) would not be in Default in the performance of any covenant
or condition of this Indenture. A purchase by a Subsidiary of
all or substantially all of the assets of another entity shall not be deemed to be a purchase of
such assets by the Company; and (iii) the Company shall have delivered to the Trustee and Officer’s Certificate and an Opinion
of Counsel, each stating that such consolidation, merger, conveyance, or other transfer or lease
and such supplemental indenture comply with this Article and that all conditions precedent herein
provided for relating to such transactions have been complied with.

          (b) Upon any consolidation with or merger into any other entity, or any sale other than for
cash, or any conveyance or lease of all or substantially all of the assets of the Company in
accordance with this Section 6.04, the successor entity formed by such consolidation or into or
with which the Company is merged or to which the Company is sold or to which such conveyance,
transfer or lease is made shall succeed to, and be substituted for, and may exercise every right
and power of, the Company under this Indenture with the same effect as if such successor entity had
been named as the Company herein, and thereafter, except in the case of a lease, the predecessor
Company shall be relieved of all obligations and covenants under this Indenture and the Securities,
and from time to time such entity may exercise each and every right and power of the Company under
this Indenture, in the name of the Company, or in its own name; and any act or proceeding by any
provision of this Indenture required or permitted to be done by the Board of Directors or any
officer of the Company may be done with like force and effect by the like board or officer of any
entity that shall at the time be the successor of the Company hereunder. In the event of any such
sale or conveyance, but not any such lease, the Company (or any successor entity which shall
theretofore have become such in the manner described in this Section 6.04) shall be discharged from
all obligations and covenants under this Indenture and the Securities and may thereupon be
dissolved and liquidated.

     Section 6.05 Compliance Certificate. Except as otherwise provided as contemplated by Section 3.01 with respect to any series of
Securities, the Company shall furnish to the Trustee annually, within 120 days after the end of
each fiscal year, a brief certificate from the principal executive officer, principal financial
officer or principal accounting officer as to his or her knowledge of the Company’s compliance with
all conditions and covenants under this Indenture (which compliance shall be determined without
regard to any period of grace or requirement of notice provided under this Indenture) and, in the
event of any Default, specifying each such Default and the nature and status thereof of which such
person may have knowledge. Such certificates need not comply with Section 16.01 of this Indenture.

     Section 6.06 Conditional Waiver by Holders of Securities. Anything in this Indenture to the contrary notwithstanding, the Company may fail or omit in any
particular instance to comply with a covenant or condition set forth herein with respect to any
series of Securities if the

33

 

Company shall have obtained and filed with the Trustee, prior to the time of such failure or
omission, evidence (as provided in Article VIII) of the consent of the Holders of a majority in
aggregate principal amount of the Securities of such series at the time Outstanding, either waiving
such compliance in such instance or generally waiving compliance with such covenant or condition,
but no such waiver shall extend to or affect such covenant or condition except to the extent so
expressly waived, or impair any right consequent thereon and, until such waiver shall have become
effective, the obligations of the Company and the duties of the Trustee in respect of any such
covenant or condition shall remain in full force and effect.

     Section 6.07 Statement by Officers as to Default. The Company shall deliver to the Trustee as soon as possible and in any event within 30 days
after the Company becomes aware of the occurrence of any Event of Default or an event which, with
the giving of notice or the lapse of time or both, would constitute an Event of Default, an
Officer’s Certificate setting forth the details of such Event of Default or Default and the action
which the Company proposes to take with respect thereto.

ARTICLE VII

REMEDIES OF TRUSTEE AND SECURITYHOLDERS

     Section 7.01 Events of Default. Except where otherwise indicated by the context or where the term is otherwise defined for a
specific purpose, the term “Event of Default” as used in this Indenture with respect to Securities
of any series shall mean one of the following described events unless it is either inapplicable to
a particular series or it is specifically deleted or modified in the manner contemplated in Section
3.01:

          (a) the failure of the Company to pay any installment of interest on any Security of such
series when and as the same shall become payable, which failure shall have continued unremedied for
a period of 30 days;

          (b) the failure of the Company to pay the principal of (and premium, if any, on) any Security
of such series, when and as the same shall become payable, whether at Maturity as therein
expressed, by call for redemption (otherwise than pursuant to a sinking fund), by declaration as
authorized by this Indenture or otherwise;

          (c) the failure of the Company to pay a sinking fund installment, if any, when and as the same
shall become payable by the terms of a Security of such series, which failure shall have continued
unremedied for a period of 30 days;

          (d) the failure of the Company, subject to the provisions of Section 6.06, to perform any
covenants or agreements contained in this Indenture (including any indenture supplemental hereto
pursuant to which the Securities of such series were issued as contemplated by Section 3.01) (other
than a covenant or agreement which has been expressly included in this Indenture solely for the
benefit of a series of Securities other than that series and other than a covenant or agreement a
default in the performance of which is elsewhere in this Section 7.01 specifically addressed),
which failure shall not have been remedied, or without provision deemed to be adequate for the
remedying thereof having been made, for a period of 90 days after written

34

 

notice shall have been given to the Company by the Trustee or shall have been given to the
Company and the Trustee by Holders of 25% or more in aggregate principal amount of the Securities
of such series then Outstanding, specifying such failure, requiring the Company to remedy the same
and stating that such notice is a “Notice of Default” hereunder;

          (e) the entry by a court having jurisdiction in the premises of a decree or order for relief
in respect of the Company in an involuntary case under the federal bankruptcy laws, as now or
hereafter constituted, or any other applicable federal or state bankruptcy, insolvency or other
similar law now or hereafter in effect, or appointing a receiver, liquidator, assignee, custodian,
trustee or sequestrator (or similar official) of the Company or of substantially all the property
of the Company or ordering the winding-up or liquidation of its affairs and such decree or order
shall remain unstayed and in effect for a period of 90 consecutive days;

          (f) the commencement by the Company of a voluntary case under the federal bankruptcy laws, as
now or hereafter constituted, or any other applicable federal or state bankruptcy, insolvency or
other similar law now or hereafter in effect, or the consent by the Company to the entry of an
order for relief in an involuntary case under any such law, or the consent by the Company to the
appointment of or taking possession by a receiver, liquidator, assignee, trustee, custodian or
sequestrator (or similar official) of the Company or of substantially all the property of the
Company or the making by it of an assignment for the benefit of creditors or the admission by it in
writing of its inability to pay its debts generally as they become due, or the taking of corporate
action by the Company in furtherance of any action; or

          (g) the occurrence of any other Event of Default with respect to Securities of such series as
provided in Section 3.01.

     Notwithstanding the foregoing provisions of this Section 7.01, if the principal or any premium
or interest on any Security is payable in a Currency other than the Currency of the United States
and such Currency is not available to the Company for making payment thereof due to the imposition
of exchange controls or other circumstances beyond the control of the Company, the Company will be
entitled to satisfy its obligations to Holders of the Securities by making such payment in the
Currency of the United States in an amount equal to the Currency of the United States equivalent of
the amount payable in such other Currency, as determined by the Trustee by reference to the noon
buying rate in The City of New York for cable transfers for such Currency (“Exchange Rate”), as
such Exchange Rate is reported or otherwise made available by the Federal Reserve Bank of New York
on the date of such payment, or, if such rate is not then available, on the basis of the most
recently available Exchange Rate. Notwithstanding the foregoing provisions of this Section 7.01,
any payment made under such circumstances in the Currency of the United States where the required
payment is in a Currency other than the Currency of the United States will not constitute an Event
of Default under this Indenture.

     Section 7.02
Acceleration; Rescission and Annulment.

          (a) Except as otherwise provided as contemplated by Section 3.01 with respect to any series of
Securities, if any one or more of the above-described Events of Default (other than an Event of
Default specified in Section 7.01(e) or 7.01(f)) shall happen with respect

35

 

to Securities of any series at the time Outstanding, then, and in each and every such case,
during the continuance of any such Event of Default, the Trustee or the Holders of 25% or more in
principal amount of the Securities of such series then Outstanding may declare the principal (or,
if the Securities of that series are Original Issue Discount Securities, such portion of the
principal amount as may be specified in the terms of that series) of and all accrued but unpaid
interest on all the Securities of such series then Outstanding to be due and payable immediately by
a notice in writing to the Company (and to the Trustee if given by Holders), and upon any such
declaration such principal amount (or specified amount) shall become immediately due and payable.
If an Event of Default specified in Section 7.01(e) or 7.01(f) occurs and is continuing, then in
every such case, the principal amount of all of the Securities of that series then Outstanding
shall automatically, and without any declaration or any other action on the part of the Trustee or
any Holder, become due and payable immediately. Upon payment of such amounts in the Currency in
which such Securities are denominated (subject to Section 7.01 and except as otherwise provided
pursuant to Section 3.01), all obligations of the Company in respect of the payment of principal of
and interest on the Securities of such series shall terminate.

          (b) This provision, however, is subject to the condition that, at any time after the principal
of all the Securities of such series, to which any one or more of the above-described Events of
Default is applicable, shall have been so declared to be due and payable, and before a judgment or
decree for payment of the money due has been obtained by the Trustee as hereinafter provided in
this Article, the Event of Default giving rise to such declaration of acceleration shall, without
further act, be deemed to have been waived, and such declaration and its consequences shall,
without further act, be deemed to have been rescinded and annulled, if:

     (i) the Company has paid or deposited with the Trustee or Paying Agent a sum in the
Currency in which such Securities are denominated (subject to Section 7.01 and except as
otherwise provided pursuant to Section 3.01) sufficient to pay

     (A) all amounts owing the Trustee and any predecessor trustee hereunder under
Section 11.01(a) (provided, however, that all sums payable under this clause (A)
shall be paid in U.S. Dollars);

     (B) all arrears of interest, if any, upon all the Securities of such series
(with interest, to the extent that interest thereon shall be legally enforceable, on
any overdue installment of interest at the rate borne by the Securities at the rate
or rates prescribed therefor in such Securities); and

     (C) the principal of and premium, if any, on any Securities of such series that
have become due otherwise than by such declaration of acceleration and interest
thereon;

     (ii) every other Default and Event of Default with respect to Securities of that
series, other than the non-payment of the principal of Securities of that series which have
become due solely by such declaration of acceleration, have been cured or waived as provided
in Section 7.06.

36

 

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

          (d) For all purposes under this Indenture, if a portion of the principal of any Original Issue
Discount Securities shall have been accelerated and declared due and payable pursuant to the
provisions hereof, then, from and after such declaration, unless such declaration has been
rescinded and annulled, the principal amount of such Original Issue Discount Securities shall be
deemed, for all purposes hereunder, to be such portion of the principal thereof as shall be due and
payable as a result of such acceleration, and payment of such portion of the principal thereof as
shall be due and payable as a result of such acceleration, together with interest, if any, thereon
and all other amounts owing thereunder, shall constitute payment in full of such Original Issue
Discount Securities.

     Section 7.03 Other Remedies. If the Company shall fail for a period of 30 days to pay any installment of interest on the
Securities of any series or shall fail to pay the principal of and premium, if any, on any of the
Securities of such series when and as the same shall become due and payable, whether at Maturity,
or by call for redemption (other than pursuant to the sinking fund), by declaration as authorized
by this Indenture, or otherwise, or shall fail for a period of 30 days to make any required sinking
fund payment as to a series of Securities, then, upon demand of the Trustee, the Company will pay
to the Paying Agent for the benefit of the Holders of Securities of such series then Outstanding
the whole amount which then shall have become due and payable on all the Securities of such series,
with interest on the overdue principal and premium, if any, and (so far as the same may be legally
enforceable) on the overdue installments of interest at the rate borne by the Securities of such
series, and all amounts owing the Trustee and any predecessor trustee hereunder under Section
11.01(a).

     In case the Company shall fail forthwith to pay such amounts upon such demand, the Trustee, in
its own name and as trustee of an express trust, shall be entitled and empowered to institute any
action or proceeding at law or in equity for the collection of the sums so due and unpaid, and may
prosecute any such action or proceeding to judgment or final decree, and may enforce any such
judgment or final decree against the Company or any other obligor upon the Securities of such
series, and collect the moneys adjudged or decreed to be payable out of the property of the Company
or any other obligor upon the Securities of such series, wherever situated, in the manner provided
by law. Every recovery of judgment in any such action or other proceeding, subject to the payment
to the Trustee of all amounts owing the Trustee and any predecessor trustee hereunder under Section
11.01(a), shall be for the ratable benefit of the Holders of such series of Securities which shall
be the subject of such action or proceeding. All rights of action upon or under any of the
Securities or this Indenture may be enforced by the Trustee without the possession of any of the
Securities and without the production of any thereof at any trial or any proceeding relative
thereto.

     Section 7.04 Trustee as Attorney-in-Fact. The Trustee is hereby appointed, and each and every Holder of the Securities, by receiving and
holding the same, shall be conclusively deemed to have appointed the Trustee, the true and lawful
attorney-in-fact of such Holder, with authority to make or file (whether or not the Company shall
be in Default in respect of the payment of the principal of, or interest on, any of the
Securities), in its own name and as trustee of an express trust or otherwise as it shall deem
advisable, in any receivership, insolvency,

37

 

liquidation, bankruptcy, reorganization or other judicial proceeding relative to the Company or any
other obligor upon the Securities or to their respective creditors or property, any and all claims,
proofs of claim, proofs of debt, petitions, consents, other papers and documents and amendments of
any thereof, as may be necessary or advisable in order to have the claims of the Trustee and any
predecessor trustee hereunder and of the Holders of the Securities allowed in any such proceeding
and to collect and receive any moneys or other property payable or deliverable on any such claim,
and to execute and deliver any and all other papers and documents and to do and perform any and all
other acts and things, as it may deem necessary or advisable in order to enforce in any such
proceeding any of the claims of the Trustee and any predecessor trustee hereunder and of any of
such Holders in respect of any of the Securities; and any receiver, assignee, trustee, custodian or
debtor in any such proceeding is hereby authorized, and each and every taker or Holder of the
Securities, by receiving and holding the same, shall be conclusively deemed to have authorized any
such receiver, assignee, trustee, custodian or debtor, to make any such payment or delivery only to
or on the order of the Trustee, and to pay to the Trustee any amount due it and any predecessor
trustee hereunder under Section 11.01(a); provided, however, that nothing herein contained shall be
deemed to authorize or empower the Trustee to consent to or accept or adopt, on behalf of any
Holder of Securities, any plan of reorganization or readjustment affecting the Securities or the
rights of any Holder thereof, or to authorize or empower the Trustee to vote in respect of the
claim of any Holder of any Securities in any such proceeding.

     Section 7.05 Priorities. Any moneys or properties collected by the Trustee with respect to a series of Securities under
this Article VII and any money or other property distributable in respect of the Company’s
obligations under this Indenture after an Event of Default shall be applied in the order following,
at the date or dates fixed by the Trustee for the distribution of such moneys or properties and, in
the case of the distribution of such moneys or properties on account of the Securities of any
series, upon presentation of the Securities of such series, and stamping thereon the payment, if
only partially paid, and upon surrender thereof, if fully paid:

     First: To the payment of all amounts due to the Trustee and any predecessor trustee
hereunder under Section 11.01(a).

     Second: In case the principal of the Outstanding Securities of such series shall not
have become due and be unpaid, to the payment of interest on the Securities of such series,
in the chronological order of the Maturity of the installments of such interest, with
interest (to the extent that such interest has been collected by the Trustee) upon the
overdue installments of interest at the rate borne by such Securities, such payments to be
made ratably to the Persons entitled thereto.

     Third: In case the principal of the Outstanding Securities of such series shall have
become due, by declaration or otherwise, to the payment of the whole amount then owing and
unpaid upon the Securities of such series for principal and premium, if any, and interest,
with interest on the overdue principal and premium, if any, and (to the extent that such
interest has been collected by the Trustee) upon overdue installments of interest at the
rate borne by the Securities of such series, and in case such moneys shall be insufficient
to pay in full the whole amounts so due and unpaid upon the Securities of such series, then
to the payment of such principal and premium, if any, and interest

38

 

without preference or priority of principal and premium, if any, over interest, or of
interest over principal and premium, if any, or of any installment of interest over any
other installment of interest, or of any Security of such series over any other Security of
such series, ratably to the aggregate of such principal and premium, if any, and accrued and
unpaid interest.

Any surplus then remaining shall be paid to the Company or as directed by a court of competent
jurisdiction.

     Section 7.06 Control by Securityholders; Waiver of Past Defaults. The Holders of a majority in principal amount of the Securities of any series at the time
Outstanding may direct the time, method and place of conducting any proceeding for any remedy
available to the Trustee hereunder, or of exercising any trust or power hereby conferred upon the
Trustee with respect to the Securities of such series, provided, however, that the Trustee shall
have the right to decline to follow any such direction if the Trustee being advised by counsel
determines that the action so directed may not lawfully be taken or would be unduly prejudicial to
Holders not joining in such direction or would involve the Trustee in personal liability. Prior to
any declaration accelerating the Maturity of the Securities of any series, the Holders of a
majority in aggregate principal amount of such series of Securities at the time Outstanding may on
behalf of the Holders of all of the Securities of such series waive any past Default or Event of
Default hereunder and its consequences except a Default in the payment of interest or any premium
on or the principal of the Securities of such series. Upon any such waiver the Company, the
Trustee and the Holders of the Securities of such series shall be restored to their former
positions and rights hereunder, respectively; but no such waiver shall extend to any subsequent or
other Default or Event of Default or impair any right consequent thereon. Whenever any Default or
Event of Default hereunder shall have been waived as permitted by this Section 7.06, said Default
or Event of Default shall for all purposes of the Securities of such series and this Indenture be
deemed to have been cured and to be not continuing.

     Section 7.07 Limitation on Suits. No Holder of any Security of any series shall have any right to institute any action, suit or
proceeding at law or in equity for the execution of any trust hereunder or for the appointment of a
receiver or for any other remedy hereunder, in each case with respect to an Event of Default with
respect to such series of Securities, unless such Holder previously shall have given to the Trustee
written notice of one or more of the Events of Default herein specified with respect to such series
of Securities, and unless also the Holders of 25% in principal amount of the Securities of such
series then Outstanding shall have requested the Trustee in writing to take action in respect of
the matter complained of, and unless also there shall have been offered to the Trustee security and
indemnity satisfactory to it against the costs, expenses and liabilities to be incurred therein or
thereby, and the Trustee, for 60 days after receipt of such notification, request and offer of
indemnity, shall have neglected or refused to institute any such action, suit or proceeding; and
such notification, request and offer of indemnity are hereby declared in every such case to be
conditions precedent to any such action, suit or proceeding by any Holder of any Security of such
series; it being understood and intended that no one or more of the Holders of Securities of such
series shall have any right in any manner whatsoever by his, her, its or their action to enforce
any right hereunder, except in the manner herein provided, and that every action, suit or
proceeding at law or in equity shall be instituted, had and maintained in the manner herein
provided and for the equal benefit of all Holders of the

39

 

Outstanding Securities of such series; provided, however, that nothing in this Indenture or in the
Securities of such series shall affect or impair the obligation of the Company, which is absolute
and unconditional, to pay the principal of, premium, if any, and interest on the Securities of such
series to the respective Holders of such Securities at the respective due dates in such Securities
stated, or affect or impair the right, which is also absolute and unconditional, of such Holders to
institute suit to enforce the payment thereof.

     Section 7.08 Undertaking for Costs. All parties to this Indenture and each Holder of any Security, by such Holder’s acceptance
thereof, shall be deemed to have agreed that any court may in its discretion require, in any
action, suit or proceeding for the enforcement of any right or remedy under this Indenture, or in
any action, suit or proceeding against the Trustee for any action taken or omitted by it as
Trustee, the filing by any party litigant in such action, suit or proceeding of an undertaking to
pay the costs of such action, suit or proceeding, and that such court may in its discretion assess
reasonable costs, including reasonable attorneys’ fees, against any party litigant in such action,
suit or proceeding, having due regard to the merits and good faith of the claims or defenses made
by such party litigant; provided, however, that the provisions of this Section 7.08 shall not apply
to any action, suit or proceeding instituted by the Trustee, to any action, suit or proceeding
instituted by any one or more Holders of Securities holding in the aggregate more than 10% in
principal amount of the Securities of any series Outstanding, or to any action, suit or proceeding
instituted by any Holder of Securities of any series for the enforcement of the payment of the
principal of or premium, if any, or the interest on, any of the Securities of such series, on or
after the respective due dates expressed in such Securities.

     Section 7.09 Remedies Cumulative. No remedy herein conferred upon or reserved to the Trustee or to the Holders of Securities of
any series is intended to be exclusive of any other remedy or remedies, and each and every remedy
shall be cumulative and shall be in addition to every other remedy given hereunder or now or
hereafter existing at law or in equity or by statute. No delay or omission of the Trustee or of
any Holder of the Securities of any series to exercise any right or power accruing upon any Default
or Event of Default shall impair any such right or power or shall be construed to be a waiver of
any such Default or Event of Default or an acquiescence therein; and every power and remedy given
by this Article VII to the Trustee and to the Holders of Securities of any series, respectively,
may be exercised from time to time and as often as may be deemed expedient by the Trustee or by the
Holders of Securities of such series, as the case may be. In case the Trustee or any Holder of
Securities of any series shall have proceeded to enforce any right under this Indenture and the
proceedings for the enforcement thereof shall have been discontinued or abandoned because of waiver
or for any other reason or shall have been adjudicated adversely to the Trustee or to such Holder
of Securities, then and in every such case the Company, the Trustee and the Holders of the
Securities of such series shall severally and respectively be restored to their former positions
and rights hereunder, and thereafter all rights, remedies and powers of the Trustee and the Holders
of the Securities of such series shall continue as though no such proceedings had been taken,
except as to any matters so waived or adjudicated.

ARTICLE VIII

CONCERNING THE SECURITYHOLDERS

     Section 8.01 Evidence of Action of Securityholders. Whenever in this Indenture it is provided that the Holders of a specified percentage or a
majority in aggregate principal amount of the Securities or of any series of Securities may take
any action (including the making of any demand or request, the giving of any notice, consent or
waiver or the taking of any other action), the fact that at the time of taking any such action the
Holders of such specified percentage or majority have joined therein may be evidenced by (a) any
instrument or any number of instruments of similar tenor executed by Securityholders in person, by
an agent or by a proxy appointed in writing, including through an electronic system for tabulating
consents operated by the Depositary for such series or otherwise (such action becoming effective,
except as herein otherwise expressly provided, when such instruments or evidence of electronic
consents are delivered to the Trustee and, where it is hereby expressly required, to the Company),
or (b) by the record of the Holders of Securities voting in favor thereof at any meeting of
Securityholders duly called and held in accordance with the provisions of Article IX, or (c) by a
combination of such instrument or instruments and any such record of such a meeting of
Securityholders.

     Section 8.02 Proof of Execution or Holding of Securities. Proof of the execution of any instrument by a Securityholder or his, her or its agent or proxy
and proof of the holding by any Person of any of the Securities shall be sufficient if made in the
following manner:

          (a) The fact and date of the execution by any Person of any such instrument may be proved (i)
by the certificate of any notary public or other officer in any jurisdiction who, by the laws
thereof, has power to take acknowledgments or proof of deeds to be recorded within such
jurisdiction, that the Person who signed such instrument did acknowledge before such notary public
or other officer the execution thereof, or (ii) by the affidavit of a witness of such execution
sworn to before any such notary or other officer. Where such execution is by a Person acting in
other than his or her individual capacity, such certificate or affidavit shall also constitute
sufficient proof of his or her authority.

          (b) The ownership of Securities of any series shall be proved by the Register of such
Securities or by a certificate of the Registrar for such series.

          (c) The record of any Holders’ meeting shall be proved in the manner provided in Section 9.06.

          (d) The Trustee may require such additional proof of any matter referred to in this Section
8.02 as it shall deem appropriate or necessary, so long as the request is a reasonable one.

          (e) If the Company shall solicit from the Holders of Securities of any series any action, the
Company may, at its option fix in advance a record date for the determination of Holders of
Securities entitled to take such action, but the Company shall have no obligation to do so. Any
such record date shall be fixed at the Company’s discretion. If such a record date is fixed, such
action may be sought or given before or after the record date, but only the Holders of

41

 

Securities of record at the close of business on such record date shall be deemed to be
Holders of Securities for the purpose of determining whether Holders of the requisite proportion of
Outstanding Securities of such series have authorized or agreed or consented to such action, and
for that purpose the Outstanding Securities of such series shall be computed as of such record
date.

     Section 8.03 Persons Deemed Owners.

          (a) The Company, the Trustee and any agent of the Company or the Trustee may treat the Person
in whose name any Security is registered as the owner of such Security for the purpose of receiving
payment of principal of and premium, if any, and (subject to Section 3.08) interest, if any, 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. All payments made to any Holder, or upon his, her or its order, shall be
valid, and, to the extent of the sum or sums paid, effectual to satisfy and discharge the liability
for moneys payable upon such Security.

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

     Section 8.04 Effect of Consents. After an amendment, supplement, waiver or other action becomes effective as to any series of
Securities, a consent to it by a Holder of such series of Securities is a continuing consent
conclusive and binding upon such Holder and every subsequent Holder of the same Securities or
portion thereof, and of any Security issued upon the transfer thereof or in exchange therefor or in
place thereof, even if notation of the consent is not made on any such Security. An amendment,
supplement or waiver becomes effective in accordance with its terms and thereafter binds every
Holder.

ARTICLE IX

specified aggregate principal amount of the Securities of any one or more or all series, as the
case may be, under any other provision of this Indenture or under applicable law.

     Section 9.02 Call of Meetings by Trustee. The Trustee may at any time call a meeting of all Securityholders of all series that may be
affected by the action proposed to be taken, to take any action specified in Section 9.01, to be
held at such time and at such place as the Trustee shall determine. Notice of every meeting of the
Securityholders of a series, setting forth the time and the place of such meeting and in general
terms the action proposed to be taken at such meeting, shall be mailed to Holders of Securities of
such series at their addresses as they shall appear on the Register of the Company. Such notice
shall be mailed not less than 20 nor more than 90 days prior to the date fixed for the meeting.

     Section 9.03 Call of Meetings by Company or Securityholders. In case at any time the Company or the Holders of at least 10% in aggregate principal amount of
the Securities of a series (or of all series, as the case may be) then Outstanding that may be
affected by the action proposed to be taken, shall have requested the Trustee to call a meeting of
Securityholders of such series (or of all series), by written request setting forth in reasonable
detail the action proposed to be taken at the meeting, and the Trustee shall not have mailed the
notice of such meeting within 20 days after receipt of such request, then the Company or such
Securityholders may determine the time and the place for such meeting and may call such meeting to
take any action authorized in Section 9.01, by mailing notice thereof as provided in Section 9.02.

     Section 9.04 Qualifications for Voting. To be entitled to vote at any meeting of Securityholders, a Person shall (a) be a Holder of one
or more Securities affected by the action proposed to be taken at the meeting or (b) be a Person
appointed by an instrument in writing as proxy by a Holder of one or more such Securities. The
only Persons who shall be entitled to be present or to speak at any meeting of Securityholders
shall be the Persons entitled to vote at such meeting and their counsel and any representatives of
the Trustee and its counsel and any representatives of the Company and its counsel.

     Section 9.05 Regulation of Meetings.

          (a) Notwithstanding any other provisions of this Indenture, the Trustee may make such
reasonable regulations as it may deem advisable for any meeting of Securityholders, in regard to
proof of the holding of Securities and of the appointment of proxies, and in regard to the
appointment and duties of inspectors of votes, the submission and examination of proxies,
certificates and other evidence of the right to vote, and such other matters concerning the conduct
of the meeting as it shall deem fit.

          (b) The Trustee shall, by an instrument in writing, appoint a temporary chairman of the
meeting, unless the meeting shall have been called by the Company or by Securityholders as provided
in Section 9.03, in which case the Company or the Securityholders calling the meeting, as the case
may be, shall in like manner appoint a temporary chair. A permanent chairman and a permanent
secretary of the meeting shall be elected by majority vote of the meeting.

43

 

          (c) At any meeting of Securityholders of a series, each Securityholder of such series of such
Securityholder’s proxy shall be entitled to one vote for each $1,000 principal amount of Securities
of such series Outstanding held or represented by him; provided, however, that no vote shall be
cast or counted at any meeting in respect of any Security challenged as not Outstanding and ruled
by the chairman of the meeting to be not Outstanding. The chairman of the meeting shall have no
right to vote other than by virtue of Securities of such series held by him or her or instruments
in writing as aforesaid duly designating him or her as the Person to vote on behalf of other
Securityholders. At any meeting of the Securityholders duly called pursuant to the provisions of
Section 9.02 or 9.03 the presence of Persons holding or representing Securities in an aggregate
principal amount sufficient to take action upon the business for the transaction of which such
meeting was called shall be necessary to constitute a quorum, and any such meeting may be adjourned
from time to time by a majority of those present, whether or not constituting a quorum, and the
meeting may be held as so adjourned without further notice.

     Section 9.06 Voting. The vote upon any resolution submitted to any meeting of Securityholders of a series shall be by
written ballots on which shall be subscribed the signatures of the Holders of Securities of such
series or of their representatives by proxy and the principal amounts of the Securities of such
series held or represented by them. The permanent chairman of the meeting shall appoint two
inspectors of votes who shall count all votes cast at the meeting for or against any resolution and
who shall make and file with the secretary of the meeting their verified written reports in
duplicate of all votes cast at the meeting. A record in duplicate of the proceedings of each
meeting of Securityholders shall be prepared by the secretary of the meeting and there shall be
attached to said record the original reports of the inspectors of votes on any vote by ballot taken
thereat and affidavits by one or more Persons having knowledge of the facts setting forth a copy of
the notice of the meeting and showing that said notice was mailed as provided in Section 9.02. The
record shall show the principal amounts of the Securities voting in favor of or against any
resolution. The record shall be signed and verified by the affidavits of the permanent chairman
and secretary of the meeting and one of the duplicates shall be delivered to the Company and the
other to the Trustee to be preserved by the Trustee.

     Any record so signed and verified shall be conclusive evidence of the matters therein stated.

     Section 9.07 No Delay of Rights by Meeting. Nothing contained in this Article IX shall be deemed or construed to authorize or permit, by
reason of any call of a meeting of Securityholders of any series or any rights expressly or
impliedly conferred hereunder to make such call, any hindrance or delay in the exercise of any
right or rights conferred upon or reserved to the Trustee or to the Securityholders of such series
under any of the provisions of this Indenture or of the Securities of such series.

ARTICLE X

REPORTS BY THE COMPANY AND THE TRUSTEE AND

SECURITYHOLDERS’ LISTS

     Section 10.01 Reports by Trustee.

          (a) So long as any Securities are outstanding, the Trustee shall transmit to Holders such
reports concerning the Trustee and its actions under this Indenture as may be required pursuant to
the Trust Indenture Act at the times and in the manner provided therein. If required by Section
313(a) of the Trust Indenture Act, the Trustee shall, within 60 days after each June 15 following
the date of this Indenture deliver to Holders a brief report which complies with the provisions of
such Section 313(a).

          (b) The Trustee shall, at the time of the transmission to the Holders of Securities of any
report pursuant to the provisions of this Section 10.01, file a copy of such report with each stock
exchange upon which the Securities are listed, if any, and also with the SEC in respect of a
Security listed and registered on a national securities exchange, if any. The Company agrees to
notify the Trustee when, as and if the Securities become listed on any stock exchange.

     The Company will reimburse the Trustee for all expenses incurred in the preparation and
transmission of any report pursuant to the provisions of this Section 10.01 and of Section 10.02.

     Section 10.02 Reports by the Company. The Company shall file with the Trustee and the SEC, and transmit to Holders, such information,
documents and other reports, and such summaries thereof, as may be required pursuant to the Trust
Indenture Act at the times and in the manner provided in the Trust Indenture Act; provided that any
such information, documents or reports required to be filed with the SEC pursuant to Section 13 or
15(d) of the Exchange Act shall be filed with the Trustee within 15 days after the same is filed
with the SEC; and provided further, that the filing of the reports specified in Section 13 or 15(d)
of the Exchange Act by an entity that is the direct or indirect parent of the Company will satisfy
the requirements of this Section 10.02 so long as such entity is an obligor or guarantor on the
Securities; and provided further that the reports of such entity will not be required to include
condensed consolidating financial information for the Company in a footnote to the financial
statements of such entity.

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

     Section 10.03 Securityholders’ Lists. The Company covenants and agrees that it will furnish or cause to be furnished to the Trustee:

          (a) semi-annually, within 15 days after each Record Date, but in any event not less frequently
than semi-annually, a list in such form as the Trustee may reasonably require of

45

 

the names and addresses of the Holders of Securities to which such Record Date applies, as of
such Record Date, and

          (b) at such other times as the Trustee may request in writing, within 30 days after receipt by
the Company of any such request, a list of similar form and content as of a date not more than 15
days prior to the time such list is furnished;

provided, however, that so long as the Trustee shall be the Registrar, such lists shall not be
required to be furnished.

ARTICLE XI

CONCERNING THE TRUSTEE

     Section 11.01 Rights of Trustees; Compensation and Indemnity. The Trustee accepts the trusts created by this Indenture upon the terms and conditions hereof,
including the following, to all of which the parties hereto and the Holders from time to time of
the Securities agree:

          (a) The Trustee shall be entitled to such compensation as the Company and the Trustee shall
from time to time agree for all services rendered by it hereunder (including in any agent capacity
in which it acts). The compensation of the Trustee shall not be limited by any provision of law in
regard to the compensation of a trustee of an express trust. The Company shall reimburse the
Trustee promptly upon its request for all reasonable out-of-pocket expenses, disbursements and
advances incurred or made by the Trustee (including the reasonable expenses and disbursements of
its agents and counsel), except any such expense, disbursement or advance as may be attributable to
its negligence or willful misconduct.

     The Company also agrees to indemnify each of the Trustee and any predecessor Trustee hereunder
for, and to hold it harmless against, any and all loss, liability, damage, claim, or expense
including taxes (other than taxes based upon, measured or determined by the income of the Trustee),
arising out of or in connection with the acceptance or administration of the trust or trusts
hereunder and the performance of its duties (including in any agent capacity in which it acts), as
well as the costs and expenses of defending itself against any claim (whether asserted by the
Company, or any Holder or any other Person) or liability in connection with the exercise or
performance of any of its powers or duties hereunder, or in connection with enforcing the
provisions of this Section, except to the extent that such loss, damage, claim, liability or
expense is hereunder attributable to its negligence, or willful misconduct. The Trustee shall
notify the Company promptly of any claim for which it may seek indemnity; provided that, the
failure to so notify the Company shall not relieve the Company of its obligations. The Company
shall defend the claim and the Trustee shall cooperate in the defense. The Trustee may have
separate counsel and the Company shall pay the reasonable fees and expenses of such counsel. The
Company need not pay for any settlement made without its consent, which consent shall not be
unreasonably withheld.

     As security for the performance of the obligations of the Company under this Section 11.01(a),
the Trustee shall have a lien upon all property

46

 

and funds held or collected by the Trustee as such, except funds held in trust by the Trustee
to pay principal of and interest on particular Securities. Notwithstanding any provisions of this
Indenture to the contrary, the obligations of the Company to compensate and indemnify the Trustee
under this Section 11.01(a) and the lien provided for herein shall survive the resignation or
removal of the Trustee, any satisfaction and discharge under
Article XII and the lien provided for herein and the termination of
this Indenture for any reason. Without prejudice to its other rights
hereunder, when the Trustee
incurs expenses or renders services after an Event of Default specified in clause (e) or (f) of
Section 7.01 occurs, the expenses (including the reasonable charges and expenses of its counsel)
and compensation for the services are intended to constitute expenses of administration under any
applicable federal or state bankruptcy, insolvency or similar laws.

     “Trustee” for purposes of this Section shall include any predecessor Trustee; provided,
however, that the negligence, willful misconduct or bad faith of any Trustee hereunder shall not
affect the rights of any other Trustee hereunder.

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

          (c) The Trustee shall not be responsible in any manner whatsoever for the correctness of the
recitals herein or in the Securities (except its certificates of authentication thereon) contained,
all of which are made solely by the Company; and the Trustee shall not be responsible or
accountable in any manner whatsoever for or with respect to the validity or execution or
sufficiency of this Indenture or of the Securities (except its certificates of authentication
thereon), and the Trustee makes no representation with respect thereto. The Trustee shall not be
accountable for the use or application by the Company of any Securities, or the proceeds of any
Securities, authenticated and delivered by the Trustee in conformity with the provisions of this
Indenture.

          (d) The Trustee may consult with counsel of its selection and, except as otherwise provided in
Section 11.02, the advice of such counsel and any Opinion of Counsel shall be full and complete
authorization and protection in respect of any action taken, suffered or omitted by the Trustee
hereunder in good faith and in reliance thereon.

          (e) The Trustee, except as otherwise provided in Section 11.02, may rely upon the certificate
of the Secretary or one of the Assistant Secretaries of the Company as to the adoption of any Board
Resolution, and any request, direction, order or demand of the Company mentioned herein shall be
sufficiently evidenced by, and whenever in the administration of this Indenture the Trustee shall
deem it desirable that a matter be proved or established prior to taking, suffering or omitting any
action hereunder, the Trustee may conclusively rely upon, an Officer’s Certificate of the Company
(unless other evidence in respect thereof be herein specifically prescribed).

          (f) Subject to Section 11.05, the Trustee or any agent of the Trustee, in its individual or
any other capacity, may become the owner or pledgee of Securities and, subject to

47

 

Sections 310(b) and 311 of the Trust Indenture Act, may otherwise deal with the Company with
the same rights it would have had if it were not the Trustee or such agent.

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

          (h) Any action taken by the Trustee pursuant to any provision hereof at the request or with
the consent of any Person who at the time is the Holder of any Security shall be conclusive and
binding in respect of such Security upon all future Holders thereof or of any Security or
Securities which may be issued for or in lieu thereof in whole or in part, whether or not such
Security shall have noted thereon the fact that such request or consent had been made or given.

          (i) Subject to the provisions of Section 11.02, the Trustee may conclusively rely and shall be
fully protected in acting or refraining from acting upon any resolution, certificate, statement,
instrument, opinion, report, notice, request, consent, order, approval, bond, debenture, or 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.

          (j) Subject to the provisions of Section 11.02, the Trustee shall not be under any obligation
to exercise any of the rights or powers vested in it by this Indenture at the request, order or
direction of any of the Holders of the Securities pursuant to any provision of this Indenture,
unless such Holders of the Securities shall have offered to the Trustee security or indemnity
satisfactory to it against the costs, expenses and liabilities which may be incurred by it in
compliance with such request, order or direction.

          (k) Subject to the provisions of Section 11.02, the Trustee shall not be liable for any action
taken or omitted by it in good faith and believed by it to be authorized or within its discretion
or within the rights or powers conferred upon it by this Indenture.

          (l) Subject to the provisions of Section 11.02, the Trustee shall not be deemed to have notice
or be charged with knowledge of any Default or Event of Default unless a Responsible Officer of the
Trustee has received written notice of Default or Event of Default or unless the Holders of
not less than 25% of the Outstanding Securities notify the Trustee thereof at the Corporate Trust
Office, in either case, and such notice references the Securities and this Indenture.

          (m) Subject to the provisions of the first paragraph of Section 11.02, the Trustee shall not
be bound to make any investigation into the facts or matters stated in any resolution, certificate,
statement, instrument, opinion, report, notice, request, direction, consent, order, bond,
debenture, note, other evidence of Indebtedness or other paper or document, but the Trustee, in its
discretion, may make such further inquiry or investigation into such facts or matters as it may see
fit and, if the Trustee shall determine to make such further inquiry or investigations, it shall be
entitled to examine the books, records and premises of the company during regular business hours,
personally or by agent or attorney at the sole cost of the Company

48

 

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

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

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

          (p) the Trustee may request that the Company deliver a certificate setting forth the names of
individuals and/or titles of officers authorized at such time to take specified actions pursuant to
this Indenture, which certificate may be signed by any person authorized to sign an Officers’
Certificate, including any person specified as so authorized in any such certificate previously
delivered and not superseded;

          (q) anything in this Indenture notwithstanding, in no event shall the Trustee be liable for
special, indirect, punitive or consequential loss or damage of any kind whatsoever (including but
not limited to loss of profit); and

          (r) the Trustee shall not be responsible or liable for any failure or delay in the performance
of its obligations under this Indenture arising out of or caused, directly or indirectly, by
circumstances beyond its reasonable control, including, without limitation, acts of God;
earthquakes; fire; flood; terrorism; wars and other military disturbances; sabotage; epidemics;
riots; interruptions; loss or malfunctions of utilities, computer (hardware or software) or
communication services; accidents; labor disputes; acts of civil or military authority and
governmental action.

     Section 11.02 Duties of Trustee.

          (a) Unless and until an Event of Default specified in Section 7.01 with respect to the
Securities of any series shall have happened which at the time is continuing,

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

     (ii) the Trustee may conclusively rely, as to the truth of the statements and the
correctness of the opinions expressed therein, in the absence of bad faith on the part of
the Trustee, upon certificates and opinions furnished to it pursuant to the express
provisions of this Indenture; but in the case of any such certificates or opinions which, by
the provisions of this Indenture, are specifically required to be furnished to the Trustee,
the Trustee shall be under a duty to examine the same to determine whether or not they
conform to the requirements of this Indenture (but need not confirm or investigate the

49

 

accuracy of mathematical calculations or other facts, statements, opinions or
conclusions stated therein);

          (b) If one or more of the Events of Default specified in Section 7.01 with respect to the
Securities of any series shall have happened, then, during the continuance thereof, the Trustee
shall, with respect to such Securities, exercise such of the rights and powers vested in it by this
Indenture, and shall use the same degree of care and skill in their exercise, as a prudent person
would exercise or use under the circumstances in the conduct of such person’s own affairs.

          (c) None of the provisions of this Indenture shall be construed as relieving the Trustee from
liability for its own negligent action, its own negligent failure to act, or its own willful
misconduct, except that, anything in this Indenture contained to the contrary notwithstanding,

     (i) this Subsection shall not be construed to limit the effect of Subsections (a) or
(d) of this Section 11.02;

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

     (iii) the Trustee shall not be liable to any Holder of Securities or to any other
Person with respect to any action taken or omitted to be taken by it in good faith, in
accordance with the direction of Securityholders given as provided in Section 7.06, relating
to the time, method and place of conducting any proceeding for any remedy available to it or
exercising any trust or power conferred upon it by this Indenture.

          (d) None of the provisions of this Indenture require the Trustee to expend or risk its own
funds or otherwise to incur any financial liability in the performance of any of its duties
hereunder, or in the exercise of any of its rights or powers, if it shall have reasonable grounds
for believing that repayment of such funds or adequate indemnity against such risk or liability is
not reasonably assured to it.

          (e) 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 11.02.

     Section 11.04 Notice of Defaults. Within 90 days after the occurrence thereof, and if known to the Trustee, the Trustee shall give
to the Holders of the Securities of a series notice of each Default or Event of Default with
respect to the Securities of such series known to the Trustee, by transmitting such notice to
Holders at their addresses as the same shall then appear on the Register of the Company, unless
such Default shall have been cured or waived before the giving of such notice (the term “Default”
being hereby defined to be the events specified in Section 7.01, which are, or after notice or
lapse of time or both would become, Events of Default as defined in said Section). Except in the
case of a Default or Event of Default in payment of the principal of, premium, if any, or interest
on any of the Securities of such series when and as the

50

 

same shall become payable, or to make any sinking fund payment as to Securities of the same series,
the Trustee shall be protected in withholding such notice, if and so long as a Responsible Officer
of the Trustee in good faith determines that the withholding of such notice is in the interests of
the Holders of the Securities of such series.

     Section 11.05 Eligibility; Disqualification.

          (a) The Trustee shall at all times satisfy the requirements of TIA Section 310(a). The
Trustee shall have a combined capital and surplus of at least $50 million as set forth in its most
recent published annual report of condition, and shall have a Corporate Trust Office. If at any
time the Trustee shall cease to be eligible in accordance with the provisions of this Section
11.05, it shall resign immediately in the manner and with the effect hereinafter specified in this
Article.

          (b) The Trustee shall comply with TIA Section 310(b); provided, however, that there shall be
excluded from the operation of TIA Section 310(b)(i) the indenture, dated as of July 21, 2005 among
the Company, the guarantors named therein, and The Bank of New York, as trustee, under which the
Company’s 5.750% Senior Notes due 2010 and the Company’s 6.375% Senior Notes due 2015 are
outstanding and any indenture or indentures under which other securities or certificates of
interest or participation in other securities of the Company are outstanding if the requirements
for such exclusion set forth in TIA Section 310(b)(i) are met. If the Trustee has or shall acquire
a conflicting interest within the meaning of Section 310(b) 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. If Section 310(b) of the
Trust Indenture Act is amended any time after the date of this Indenture to change the
circumstances under which a Trustee shall be deemed to have a conflicting interest with respect to
the Securities of any series or to change any of the definitions in connection therewith, this
Section 11.05 shall be automatically amended to incorporate such changes. Nothing herein shall
preclude the Trustee from making the application referred to in the penultimate paragraph of TIA
Section 310(b).

     Section 11.06 Resignation and Notice; Removal. The Trustee, or any successor to it hereafter appointed, may at any time resign and be
discharged of the trusts hereby created with respect to any one or more or all series of Securities
by giving to the Company notice in writing. Such resignation shall take effect upon the
appointment of a successor Trustee and the acceptance of such appointment by such successor
Trustee. Any Trustee hereunder may be removed with respect to any series of Securities at any time
by the filing with such Trustee and the delivery to the Company of an instrument or instruments in
writing signed by the Holders of a majority in principal amount of the Securities of such series
then Outstanding, specifying such removal and the date when it shall become effective.

     If at any time:

     (1) the Trustee shall fail to comply with the provisions of TIA Section 310(b) 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

51

 

     (2) the Trustee shall cease to be eligible under Section 11.05 and shall fail to resign 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

     (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, (i) the Company by written notice to the Trustee may remove the Trustee and
appoint a successor Trustee with respect to all Securities, or (ii) subject to TIA Section 315(e),
any Securityholder 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.

     Upon its resignation or removal, any Trustee shall be entitled to the payment of reasonable
compensation for the services rendered hereunder by such Trustee and to the payment of all
reasonable expenses incurred hereunder and all moneys then due to it hereunder. The Trustee’s
rights to indemnification provided in Section 11.01(a) and its lien provided for therein shall
survive its resignation or removal.

     Section 11.07 Successor Trustee by Appointment.

          (a) In case at any time the Trustee shall resign, or shall be removed (unless the Trustee
shall be removed as provided in Section 11.05(b), in which event the vacancy shall be filled as
provided in said subdivision), or shall become incapable of acting, or shall be adjudged bankrupt
or insolvent, or if a receiver of the Trustee or of its property shall be appointed, or if 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 with respect to the Securities of one or
more series, a successor Trustee with respect to the Securities of that or those series (it being
understood that any such successor Trustee may be appointed with respect to the Securities of one
or more or all of such series and that at any time there shall be only one Trustee with respect to
the Securities of any series) may be appointed by the Holders of a majority in principal amount of
the Securities of that or those series then Outstanding, by an instrument or instruments in writing
signed in duplicate by such Holders and filed, one original thereof with the Company and the other
with the successor Trustee; but, until a successor Trustee shall have been so appointed by the
Holders of Securities of that or those series as herein authorized, the Company, or, in case all or
substantially all the assets of the Company shall be in the possession of one or more custodians or
receivers lawfully appointed, or of trustees in bankruptcy or reorganization proceedings (including
a trustee or trustees appointed under the provisions of the federal bankruptcy laws, as now or
hereafter constituted), or of assignees for the benefit of creditors, such receivers, custodians,
trustees or assignees, as the case may be, by an instrument in writing, shall appoint a successor
Trustee with respect to the Securities of such series. Subject to the provisions of Sections 11.05
and 11.06, upon the appointment as aforesaid of a successor Trustee with respect to the Securities
of any series, the Trustee with respect to the Securities of such series shall cease to be Trustee
hereunder. After any such appointment other than by the Holders

52

 

of Securities of that or those series, the Person making such appointment shall forthwith
cause notice thereof to be mailed to the Holders of Securities of such series at their addresses as
the same shall then appear on the Register of the Company but any successor Trustee with respect to
the Securities of such series so appointed shall, immediately and without further act, be
superseded by a successor Trustee appointed by the Holders of Securities of such series in the
manner above prescribed, if such appointment be made prior to the expiration of one year from the
date of the mailing of such notice by the Company, or by such receivers, trustees or assignees.

          (b) If any Trustee with respect to the Securities of one or more series shall resign or be
removed and a successor Trustee shall not have been appointed by the Company or by the Holders of
the Securities of such series or, if any successor Trustee so appointed shall not have accepted its
appointment within 30 days after such appointment shall have been made, the resigning Trustee at
the expense of the Company may apply to any court of competent jurisdiction for the appointment of
a successor Trustee. If in any other case a successor Trustee shall not be appointed pursuant to
the foregoing provisions of this Section 11.06 within three months after such appointment might
have been made hereunder, the Holder of any Security of the applicable series or any retiring
Trustee at the expense of the Company may apply to any court of competent jurisdiction to appoint a
successor Trustee. Such court may thereupon, in any such case, after such notice, if any, as such
court may deem proper and prescribe, appoint a successor Trustee.

          (c) Any successor Trustee appointed hereunder with respect to the Securities of one or more
series shall execute, acknowledge and deliver to its predecessor Trustee and to the Company, or to
the receivers, trustees, assignees or court appointing it, as the case may be, an instrument
accepting such appointment hereunder, and thereupon such successor Trustee, without any further
act, deed or conveyance, shall become vested with all the authority, rights, powers, trusts,
immunities, duties and obligations with respect to such series of such predecessor Trustee with
like effect as if originally named as Trustee hereunder, and such predecessor Trustee, upon payment
of its charges and disbursements then unpaid, shall thereupon become obligated to pay over, and
such successor Trustee shall be entitled to receive, all moneys and properties held by such
predecessor Trustee as Trustee hereunder, subject nevertheless to its lien provided for in Section
11.01(a). Nevertheless, on the written request of the Company or of the successor Trustee or of
the Holders of at least 10% in principal amount of the Securities of such series then Outstanding,
such predecessor Trustee, upon payment of its said charges and disbursements, shall execute and
deliver an instrument transferring to such successor Trustee upon the trusts herein expressed all
the rights, powers and trusts of such predecessor Trustee and shall assign, transfer and deliver to
the successor Trustee all moneys and properties held by such predecessor Trustee, subject
nevertheless to its lien provided for in Section 11.01(a); and, upon request of any such successor
Trustee and the Company shall make, execute, acknowledge and deliver any and all instruments in
writing for more fully and effectually vesting in and confirming to such successor Trustee all such
authority, rights, powers, trusts, immunities, duties and obligations.

     Section 11.08 Successor Trustee by Merger. Any Person into which the Trustee or any successor to it in the trusts created by this Indenture
shall be merged or converted, or any Person with which it or any successor to it shall be
consolidated, or any Person resulting from any merger, conversion or consolidation to which the
Trustee or any such successor to it shall be a

53

 

party, or any Person to which the Trustee or any successor to it shall sell or otherwise transfer
all or substantially all of the corporate trust business of the Trustee, shall be the successor
Trustee under this Indenture without the execution or filing of any paper or any further act on the
part of any of the parties hereto; provided that such Person shall be otherwise qualified and
eligible under this Article. In case at the time such successor to the Trustee shall succeed to
the trusts created by this Indenture with respect to one or more series of Securities, any of such
Securities shall have been authenticated but not delivered by the Trustee then in office, any
successor to such Trustee may adopt the certificate of authentication of any predecessor Trustee,
and deliver such Securities so authenticated; and in case at that time any of the Securities shall
not have been authenticated, any successor to the Trustee may authenticate such Securities either
in the name of any predecessor hereunder or in the name of the successor Trustee; and in all such
cases such certificates shall have the full force which it is anywhere in the Securities or in this
Indenture provided that the certificate of the Trustee shall have; provided, however, that the
right to adopt the certificate of authentication of any predecessor Trustee or authenticate
Securities in the name of any predecessor Trustee shall apply only to its successor or successors
by merger, conversion or consolidation.

     Section 11.09 Right to Rely on Officer’s Certificate. Subject to Section 11.02, and subject to the provisions of Section 16.01 with respect to the
certificates required thereby, whenever in the administration of the provisions of 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 (unless other evidence in respect thereof be
herein specifically prescribed) may, in the absence of bad faith on the part of the Trustee, be
deemed to be conclusively proved and established by an Officer’s Certificate with respect thereto
delivered to the Trustee, and such Officer’s Certificate, in the absence of bad faith on the part
of the Trustee, shall be full warrant to the Trustee for any action taken, suffered or omitted by
it under the provisions of this Indenture in reliance thereon.

     Section 11.10 Appointment of Authenticating Agent. The Trustee may appoint an agent (the “Authenticating Agent”) reasonably acceptable to the
Company to authenticate the Securities, and the Trustee shall give written notice of such
appointment to all Holders of Securities of the series with respect to which such Authenticating
Agent will serve. Unless limited by the terms of such appointment, any such Authenticating Agent
may authenticate Securities whenever the Trustee may do so. Each reference in this Indenture to
authentication by the Trustee includes authentication by the Authenticating Agent. 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.

     Each Authenticating Agent shall at all times be a corporation organized and doing business and
in good standing under the laws of the United States, any State thereof or the District of
Columbia, authorized under such laws to act as Authenticating Agent, having a combined capital and
surplus of not less than $50,000,000 and subject to supervision or examination by Federal or State
authority. If such corporation 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
Article XI, the combined capital and surplus of such corporation shall be deemed to be its combined
capital and surplus as set forth in its most recent report of condition so published. If at any
time an Authenticating Agent shall cease to be eligible in

54

 

accordance with the provisions of this Article XI, it shall resign immediately in the manner
and with the effect specified in this Article XI.

     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 of 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 Article XI, 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 11.09, the
Trustee may appoint a successor Authenticating Agent which shall be acceptable to the Company and
shall give written notice of such appointment 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 11.09.

     The Company agrees to pay to each Authenticating Agent from time to time reasonable
compensation for its services under this Section 11.09.

     Section 11.11 Communications by Securityholders with Other Securityholders. Holders of Securities may communicate pursuant to Section 312(b) of the Trust Indenture Act with
other Holders with respect to their rights under this Indenture or the Securities. The Company,
the Trustee, the Registrar and anyone else shall have the protection of Section 312(c) of the Trust
Indenture Act with respect to such communications.

ARTICLE XII

SATISFACTION AND DISCHARGE; DEFEASANCE

     Section 12.01 Applicability of Article. If, pursuant to Section 3.01, provision is made for the defeasance of Securities of a series and
if the Securities of such series are denominated and payable only in U.S. Dollars (except as

as otherwise specified pursuant to Section 3.01 for Securities of such series. Defeasance
provisions, if any, for Securities denominated in a Foreign Currency may be specified pursuant to
Section 3.01.

     Section 12.02 Satisfaction and Discharge of Indenture. This Indenture, with respect to the Securities of any series (if all series issued under this
Indenture are not to be affected), shall, upon Company Order, cease to be of further effect (except
as to any surviving rights of

55

 

registration of transfer or exchange of such Securities herein expressly provided for and rights to
receive payments of principal of and premium, if any, and interest on such Securities) and the
Trustee, at the expense of the Company, shall execute proper instruments acknowledging satisfaction
and discharge of this Indenture, when,

          (a) either:

     (i) all Securities of such series theretofore authenticated and delivered (other than
(A) Securities that have been destroyed, lost or stolen and that have been replaced or paid
as provided in Section 3.07 and (B) Securities for whose payment money has theretofore been
deposited in trust or segregated and held in trust by the Company and thereafter repaid to
the Company or discharged from such trust, as provided in Section 6.03) have been delivered
to the Trustee for cancellation; or

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

     (A) have become due and payable, or

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

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

and in the case of (A), (B) or (C) above, has deposited or caused to be deposited with the Trustee
or Paying Agent as trust funds in trust for the purpose an amount in the Currency in which such
Securities are denominated (except as otherwise provided pursuant to Section 3.01) sufficient to
pay and discharge the entire Indebtedness on such Securities for principal and premium, if any, and
interest to the date of such deposit (in the case of Securities that have become due and payable)
or to the Stated Maturity or Redemption Date, as the case may be; provided, however, in the event a
petition for relief under federal bankruptcy laws, as now or hereafter constituted, or any other
applicable federal or state bankruptcy, insolvency or other similar law, is filed with respect to
the Company within 91 days after the deposit and the Trustee is required to return the moneys then
on deposit with the Trustee to the Company, the obligations of the Company under this Indenture
with respect to such Securities shall not be deemed terminated or discharged;

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

          (c) the Company has delivered to the Trustee an Officer’s Certificate and an Opinion of
Counsel each stating that all conditions precedent herein provided for relating to the satisfaction
and discharge of this Indenture with respect to such series have been complied with.
Notwithstanding the satisfaction and discharge of this Indenture, the obligations of the Company to
the Trustee under Section 11.01 are, if money shall have been deposited with the Trustee pursuant
to subclause (B) of clause (a)(i) of this Section, the obligations of the Trustee under Section
12.07 and the last paragraph of Section 6.03(e) shall survive.

56

 

     Section 12.03 Defeasance
upon Deposit of Moneys or U.S. Government Obligations. At the Company’s option, either (a) the Company shall be deemed to have been Discharged (as
defined below) from its obligations with respect to Securities of any series on the first day after
the applicable conditions set forth below have been satisfied or (b) the Company shall cease to be
under any obligation to comply with any term, provision or condition set forth in Section 6.04 with
respect to Securities of any series (and, if so specified pursuant to Section 3.01, any other
restrictive covenant added for the benefit of such series pursuant to Section 3.01) at any time
after the applicable conditions set forth below have been satisfied:

          (a) The Company shall have deposited or caused to be deposited irrevocably with the Trustee as
trust funds in trust, specifically pledged as security for, and dedicated solely to, the benefit of
the Holders of the Securities of such series (i) money in an amount, or (ii) U.S. Government
Obligations (as defined below) that through the payment of interest and principal in respect
thereof in accordance with their terms will provide, not later than one day before the due date of
any payment, money in an amount, or (iii) a combination of (i) and (ii), sufficient to pay and
discharge each installment of principal (including any mandatory sinking fund payments) of and
premium, if any, and interest on, the Outstanding Securities of such series on the dates such
installments of interest or principal and premium are due;

          (b) No Default with respect to the Securities of such series shall have occurred and be
continuing on the date of such deposit (other than a Default resulting from the borrowing of funds
and the grant of any related liens to be applied to such deposit); and

          (c) The Company shall have delivered to the Trustee an Opinion of Counsel to the effect that
Holders of the Securities of such series will not recognize income, gain or loss for U.S. federal
income tax purposes as a result of the Company’s exercise of its option under this Section and will
be subject to federal income tax on the same amounts and in the same manner and at the same times
as would have been the case if such action had not been exercised and, in the case of the
Securities of such series being Discharged accompanied by a ruling to that effect received from or
published by the Internal Revenue Service.

     “Discharged” means that the Company shall be deemed to have paid and discharged the entire
Indebtedness represented by, and obligations under, the Securities of such series and to have
satisfied all the obligations under this Indenture relating to the Securities of such series (and
the Trustee, at the expense of the Company, shall execute proper instruments acknowledging the
same), except (A) the rights of Holders of Securities of such series to receive, from the trust
fund described in clause (a) above, payment of the principal of and premium, if any, and interest
on such Securities when such payments are due, (B) the Company’s obligations with respect to
Securities of such series under Sections 3.04, 3.06, 3.07, 6.02, 12.06 and 12.07 and (C) the
rights, powers, trusts, duties and immunities of the Trustee hereunder.

     “U.S. Government Obligations” means securities that are (i) direct obligations of the United
States for the payment of which its full faith and credit is pledged or (ii) obligations of a
Person controlled or supervised by and acting as an agency or instrumentality of the United States
the timely of payment of which is unconditionally guaranteed as a full faith and credit obligation
by the United States, that, in either case under clauses (i) or (ii) are not callable or redeemable
at the action of the issuer thereof, and shall also include a depositary receipt issued

57

 

by a bank or trust company as custodian with respect to any such U.S. Government Obligation or
a specific payment of interest on or principal of any such U.S. Government Obligation held by such
custodian for the account of the holder of a depositary receipt; 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 interest on or principal of the U.S. Government
Obligation evidenced by such depositary receipt.

     Section 12.04 Repayment to Company. The Trustee and any Paying Agent shall promptly pay to the Company (or to its designee) upon
Company Order any excess moneys or U.S. Government Obligations held by them at any time, including
any such moneys or obligations held by the Trustee under any escrow trust agreement entered into
pursuant to Section 12.06. The provisions of the last paragraph of Section 6.03 shall apply to any
money held by the Trustee or any Paying Agent under this Article that remains unclaimed for two
years after the Maturity of any series of Securities for which money or U.S. Government Obligations
have been deposited pursuant to Section 12.03.

     Section 12.05 Indemnity for U.S. Government Obligations. The Company shall pay and shall indemnify the Trustee against any tax, fee or other charge
imposed on or assessed against the deposited U.S. Government Obligations or the principal or
interest received on such U.S. Government Obligations.

     Section 12.06 Deposits to Be Held in Escrow. Any deposits with the Trustee referred to in Section 12.03 above shall be irrevocable (except to
the extent provided in Sections 12.04 and 12.07) and shall be made under the terms of an escrow
trust agreement. If any Outstanding Securities of a series are to be redeemed prior to their
Stated Maturity, whether pursuant to any optional redemption provisions or in accordance with any
mandatory or optional sinking fund requirement, the applicable escrow trust agreement shall provide
therefor and the Company shall make such arrangements as are satisfactory to the Trustee for the
giving of notice of redemption by the Trustee in the name, and at the expense, of the Company. The
agreement shall provide that, upon satisfaction of any mandatory sinking fund payment requirements,
whether by deposit of moneys, application of proceeds of deposited U.S. Government Obligations or,
if permitted, by delivery of Securities, the Trustee shall pay or deliver over to the Company as
excess moneys pursuant to Section 12.04 all funds or obligations then held under the agreement and
allocable to the sinking fund payment requirements so satisfied.

     If Securities of a series with respect to which such deposits are made may be subject to later
redemption at the option of the Company or pursuant to optional sinking fund payments, the
applicable escrow trust agreement may, at the option of the Company, provide therefor. In the case
of an optional redemption in whole or in part, such agreement shall require the Company to deposit
with the Trustee on or before the date notice of redemption is given funds sufficient to pay the
Redemption Price of the Securities to be redeemed together with all unpaid interest thereon to the
Redemption Date. Upon such deposit of funds, the Trustee shall pay or deliver over to the Company
as excess funds pursuant to Section 12.04 all funds or obligations then held under such agreement
and allocable to the Securities to be redeemed. In the case of exercise of optional sinking fund
payment rights by the Company, such agreement shall, at the option of the Company, provide that
upon deposit by the Company with the Trustee of funds pursuant to such

58

 

exercise the Trustee shall pay or deliver over to the Company as excess funds pursuant to
Section 12.04 all funds or obligations then held under such agreement for such series and allocable
to the Securities to be redeemed.

     Section 12.07 Application of Trust Money.

          (a) Neither the Trustee nor any other paying agent shall be required to pay interest on any
moneys deposited pursuant to the provisions of this Indenture, except such as it shall agree with
the Company in writing to pay thereon. Any moneys so deposited for the payment of the principal
of, or premium, if any, or interest on the Securities of any series and remaining unclaimed for two
years after the date of the maturity of the Securities of such series or the date fixed for the
redemption of all the Securities of such series at the time outstanding, as the case may be, shall
be repaid by the Trustee or such other paying agent to the Company upon its written request and
thereafter, anything in this Indenture to the contrary notwithstanding, any rights of the Holders
of Securities of such series in respect of which such moneys shall have been deposited shall be
enforceable only against the Company, and all liability of the Trustee or such other paying agent
with respect to such moneys shall thereafter cease.

          (b) Subject to the provisions of the foregoing paragraph, any moneys which at any time shall
be deposited by the Company or on its behalf with the Trustee or any other paying agent for the
purpose of paying the principal of, premium, if any, and interest on any of the Securities shall be
and are hereby assigned, transferred and set over to the Trustee or such other paying agent in
trust for the respective Holders of the Securities for the purpose for which such moneys shall have
been deposited; but such moneys need not be segregated from other funds except to the extent

be as set forth in the Officer’s Certificate or established in the supplemental indenture under
which the Securities of such series are issued.

time Outstanding, notwithstanding any of the provisions of Section 14.02.

61

 

     Section 14.02 With Consent of Securityholders; Limitations.

          (a) With the consent of the Holders (evidenced as provided in Article VIII) of a majority in
aggregate principal amount of the Outstanding Securities of each series affected by such

any time, enter into an indenture or indentures supplemental hereto for the purpose of adding any
provisions to or changing in any manner or eliminating any provisions of this Indenture or of
modifying in any manner the rights of the Holders of the Securities of such series to be affected;
provided, however, that no such supplemental indenture shall, without the consent of the Holder of
each Outstanding Security of each such series affected thereby,

     (i) extend the Stated Maturity of the principal of, or any installment of interest on,
any Security, or reduce the principal amount thereof or the interest thereon or any premium
payable upon redemption thereof, or extend the Stated Maturity of, or change the Currency in

     (iv) modify, without the written consent of the Trustee, the rights, duties or
immunities of the Trustee.

or which modifies the rights of the Holders of Securities of such series with respect to such
covenant or other provision, shall be deemed not to affect the rights under this Indenture of the
Holders of Securities of any other series.

62

 

          (c) It shall not be necessary for the consent of the Securityholders under this Section 14.02
to approve the particular form of any proposed supplemental indenture, but it shall be sufficient
if such consent shall approve the substance thereof.

          (d) The Company may set a record date for purposes of determining the identity of the Holders
of each series of Securities entitled to give a written consent or waive compliance by the Company
as authorized or permitted by this Section. Such record date shall not be more than 30 days prior

furnished to the Trustee prior to such solicitation pursuant to Section 312 of the Trust Indenture
Act.

pursuant to the provisions of this Section 14.02, the Company shall mail a notice, setting forth in
general terms the substance of such supplemental indenture, to the Holders of Securities at their

of Counsel required by Section 16.01 stating that the execution of such supplemental indenture is
authorized or permitted by this Indenture, the Trustee shall join with the Company in the execution

shall be fully protected in relying upon such Officer’s Certificate and an Opinion of Counsel.

     Section 14.04 Effect of Execution of Supplemental Indenture. Upon the execution of any supplemental indenture pursuant to the provisions of this Article XIV,

herein otherwise expressly provided, the respective rights, limitations of rights, obligations,
duties and immunities under this Indenture of the Trustee, the Company and the Holders of all of
the Securities or of the Securities of any series affected, as the case may be, shall thereafter be
determined, exercised and enforced hereunder subject in all respects to such modifications and
amendments, and all the terms and conditions of any such supplemental indenture shall be and be
deemed to be part of the terms and conditions of this Indenture for any and all purposes.

ARTICLE XV

SUBORDINATION OF SECURITIES

     Section 15.01 Agreement to Subordinate. In the event a series of Securities is designated as subordinated pursuant to Section 3.01, and
except as otherwise provided in a Company Order or in one or more indentures supplemental hereto,
the Company, for itself, its successors and assigns, covenants and agrees, and each Holder of
Securities of such series by his, her or its acceptance thereof, likewise covenants and agrees,
that the payment of the principal of (and premium, if any) and interest, if any, on each and all of
the Securities of such series is hereby expressly subordinated, to the extent and in the manner
hereinafter set forth, in right of payment to the prior payment in full of all Senior Indebtedness.
In the event a series of Securities is not designated as subordinated pursuant to Section 3.01(s),
this Article XV shall have no effect upon the Securities.

     Section 15.02 Distribution on Dissolution, Liquidation and Reorganization; Subrogation of
Securities. Subject to Section 15.01, upon any distribution of assets of the Company upon any dissolution,
winding up, liquidation or reorganization of the Company, whether in bankruptcy, insolvency,
reorganization or receivership proceedings or upon an assignment for the benefit of creditors or
any other marshalling of the assets and liabilities of the Company or otherwise (subject to the
power of a court of competent jurisdiction to make other equitable provision reflecting the rights
conferred in this Indenture upon the Senior Indebtedness and the holders thereof with respect to
the Securities and the holders thereof by a lawful plan of reorganization under applicable
bankruptcy law):

          (a) the holders of all Senior Indebtedness shall be entitled to receive payment in full of the
principal thereof (and premium, if any) and interest due thereon before the Holders of the
Securities are entitled to receive any payment upon the principal (or premium, if any) or interest,
if any, on Indebtedness evidenced by the Securities; and

          (b) any payment or distribution of assets of the Company of any kind or character, whether in
cash, property or securities, to which the Holders of the Securities or the Trustee would be
entitled except for the provisions of this Article XV shall be paid by the liquidation trustee or
agent or other Person making such payment or distribution, whether a trustee in bankruptcy, a
receiver or liquidating trustee or otherwise, directly to the holders of Senior Indebtedness or
their representative or representatives or to the trustee or trustees under any indenture under
which any instruments evidencing any of such Senior Indebtedness may have been issued, ratably
according to the aggregate amounts remaining unpaid on account of the principal of (and premium, if
any) and interest on the Senior Indebtedness held or represented by each, to the extent necessary
to make payment in full of all Senior Indebtedness remaining unpaid, after giving effect to any
concurrent payment or distribution to the holders of such Senior Indebtedness; and

64

 

          (c) in the event that, notwithstanding the foregoing, any payment or distribution of assets of
the Company of any kind or character, whether in cash, property or securities prohibited by the
foregoing, shall be received by the Trustee or the Holders of the Securities before all Senior
Indebtedness is paid in full, such payment or distribution shall be paid over, upon written notice
to a Responsible Officer of the Trustee, to the holder of such Senior Indebtedness or his, her or
its representative or representatives or to the trustee or trustees under any indenture under which
any instrument evidencing any of such Senior Indebtedness may have been issued, ratably as
aforesaid, as calculated by the Company for application to payment of all Senior Indebtedness
remaining unpaid until all such Senior Indebtedness shall have been paid in full, after giving
effect to any concurrent payment or distribution to the holders of such Senior Indebtedness.

          (d) Subject to the payment in full of all Senior Indebtedness, the rights of the Holders of
the Securities shall be subrogated to the rights of the holders of Senior Indebtedness (to the
extent that distributions otherwise payable to such holder have been applied to the payment of
Senior Indebtedness) to receive payments or distributions of cash, property or securities of the
Company applicable to Senior Indebtedness until the principal of (and premium, if any) and
interest, if any, on the Securities shall be paid in full and no such payments or distributions to
the Holders of the Securities of cash, property or securities otherwise distributable to the
holders of Senior Indebtedness shall, as between the Company, its creditors other than the holders
of Senior Indebtedness, and the Holders of the Securities be deemed to be a payment by the Company
to or on account of the Securities. It is understood that the provisions of this Article XV 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 the Senior Indebtedness, on the other hand. Nothing
contained in this Article XV or elsewhere in this Indenture or in the Securities is intended to or
shall impair, as between the Company, its creditors other than the holders of Senior Indebtedness,
and the Holders of the Securities, the obligation of the Company, which is unconditional and
absolute, to pay to the Holders of the Securities the principal of (and premium, if any) and
interest, if any, on the Securities as and when the same shall become due and payable in accordance
with their terms, or to affect the relative rights of the Holders of the Securities and creditors
of the Company other than the holders of Senior Indebtedness, nor shall anything herein or in the
Securities 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 XV of the holders of Senior Indebtedness in respect of cash, property or securities of
the Company received upon the exercise of any such remedy. Upon any payment or distribution of
assets of the Company referred to in this Article XV, the Trustee, subject to the provisions of
Section 15.05, shall be entitled to conclusively rely upon a certificate of the liquidating trustee
or agent or other person making any distribution to the Trustee for the purpose of ascertaining the
Persons entitled to participate in such distribution, the holders of Senior Indebtedness and other
indebtedness of the Company, the amount thereof or payable thereon, the amount or amounts paid or
distributed thereof and all other facts pertinent thereto or to this Article XV.

     Section 15.03 No Payment on Securities in Event of Default on Senior Indebtedness. Subject to Section 15.01, no payment by the Company on account of principal (or premium, if any),
sinking funds or interest, if any, on the Securities shall be made at anytime if: (i) a default on
Senior Indebtedness exists that permits the holders of such Senior Indebtedness to accelerate

65

 

its maturity and (ii) the default is the subject of judicial proceedings or the Company has
received notice of such default. The Company may resume payments on the Securities when full
payment of amounts then due for principal (premium, if any), sinking funds and interest on Senior
Indebtedness has been made or duly provided for in money or money’s worth.

     In the event that, notwithstanding the foregoing, any payment shall be received by the Trustee
when such payment is prohibited by the preceding paragraph of this Section 15.03, such payment
shall be held in trust for the benefit of, and shall be paid over or delivered to, the holders of
such Senior Indebtedness or their respective representatives, or to the trustee or trustees under
any indenture pursuant to which any of such Senior Indebtedness may have been issued, as their
respective interests may appear, as calculated by the Company, but only to the extent that the
holders of such Senior Indebtedness (or their representative or representatives or a trustee)
notify the Trustee in writing within 90 days of such payment of the amounts then due and owing on
such Senior Indebtedness and only the amounts specified in such notice to the Trustee shall be paid
to the holders of such Senior Indebtedness.

     Section 15.04 Payments on Securities Permitted. Subject to Section 15.01, nothing contained in this Indenture or in any of the Securities shall
(a) affect the obligation of the Company to make, or prevent the Company from making, at any time
except as provided in Sections 15.02 and 15.03, payments of principal of (or premium, if any) or
interest, if any, on the Securities or (b) prevent the application by the Trustee of any moneys or
assets deposited with it hereunder to the payment of or on account of the principal of (or premium,
if any) or interest, if any, on the Securities, unless a Responsible Officer of the Trustee shall
have received at its Corporate Trust Office written notice of any fact prohibiting the making of
such payment from the Company or from the holder of any Senior Indebtedness or from the trustee for
any such holder, together with proof satisfactory to the Trustee of such holding of Senior
Indebtedness or of the authority of such trustee more than two Business Days prior to the date
fixed for such payment.

     Section 15.05 Authorization of Securityholders to Trustee to Effect Subordination. Subject to Section 15.01, each Holder of Securities by his acceptance thereof authorizes and
directs the Trustee on his, her or its behalf to take such action as may be necessary or
appropriate to effectuate the subordination as provided in this Article XV and appoints the Trustee
his attorney-in-fact for any and all such purposes.

     Section 15.06 Notices to Trustee. The Company shall give prompt written notice to a Responsible Officer of the Trustee of any fact
known to the Company that would prohibit the making of any payment of monies or assets to or by the
Trustee in respect of the Securities of any series pursuant to the provisions of this Article XV.
Subject to Section 15.01, notwithstanding the provisions of this Article XV or any other provisions
of this Indenture, neither the Trustee nor any Paying Agent (other than the Company) shall be
charged with knowledge of the existence of any Senior Indebtedness or of any fact which would
prohibit the making of any payment of moneys or assets to or by the Trustee or such Paying Agent,
unless and until a Responsible Officer of the Trustee or such Paying Agent shall have received (in
the case of a Responsible Officer of the Trustee, at the Corporate Trust Office of the Trustee)
written notice thereof from the Company or from the holder of any Senior Indebtedness or from the
trustee for any such holder, together with proof satisfactory to the Trustee of such holding of

66

 

Senior Indebtedness or of the authority of such trustee and, prior to the receipt of any such
written notice, the Trustee shall be entitled in all respects conclusively to presume that no such
facts exist; provided, however, that if at least two Business Days prior to the date upon which by
the terms hereof any such moneys or assets may become payable for any purpose (including, without
limitation, the payment of either the principal (or premium, if any) or interest, if any, on any
Security) a Responsible Officer of the Trustee shall not have received with respect to such moneys
or assets the notice provided for in this Section 15.06, then, anything herein contained to the
contrary notwithstanding, the Trustee shall have full power and authority to receive such moneys or
assets and to apply the same to the purpose for which they were received, and shall not be affected
by any notice to the contrary which may be received by it within two Business Days prior to such
date. The Trustee shall be entitled to conclusively rely on the delivery to it of a written notice
by a Person representing himself to be a holder of Senior Indebtedness (or a trustee on behalf of
such holder) to establish that such a notice has been given by a holder of Senior Indebtedness or a
trustee on behalf of any such holder. In the event that the Trustee determines in good faith that
further evidence is required with respect to the right of any Person as a holder of Senior
Indebtedness to participate in any payment or distribution pursuant to this Article XV, the Trustee
may request such Person to furnish evidence to the reasonable satisfaction of the Trustee as to the
amount of Senior Indebtedness held by such Person, the extent to which such Person is entitled to
participate in such payment or distribution and any other facts pertinent to the rights of such
Person under this Article XV and, if such evidence is not furnished, the Trustee may defer any
payment to such Person pending judicial determination as to the right of such Person to receive
such payment.

     Section 15.07 Trustee as Holder of Senior Indebtedness. Subject to Section 15.01, the Trustee in its individual capacity shall be entitled to all the
rights set forth in this Article XV in respect of any Senior Indebtedness at any time held by it to
the same extent as any other holder of Senior Indebtedness and nothing in this Indenture shall be
construed to deprive the Trustee of any of its rights as such holder. Nothing in this Article XV
shall apply to claims of, or payments to, the Trustee under or pursuant to Sections 7.05 or 11.01.

     Section 15.08 Modifications of Terms of Senior Indebtedness. Subject to Section 15.01, any renewal or extension of the time of payment of any Senior
Indebtedness or the exercise by the holders of Senior Indebtedness of any of their rights under any
instrument creating or evidencing Senior Indebtedness, including, without limitation, the waiver of
default thereunder, may be made or done all without notice to or assent from the Holders of the
Securities or the Trustee. No compromise, alteration, amendment, modification, extension, renewal
or other change of, or waiver, consent or other action in respect of, any liability or obligation
under or in respect of, or of any of the terms, covenants or conditions of any indenture or other
instrument under which any Senior Indebtedness is outstanding or of such Senior Indebtedness,
whether or not such release is in accordance with the provisions of any applicable document, shall
in any way alter or affect any of the provisions of this Article XV or of the Securities relating
to the subordination thereof.

     Section 15.09 Reliance on Judicial Order or Certificate of Liquidating Agent. Subject to Section 15.01, upon any payment or distribution of assets of the Company referred to
in this Article XV, the Trustee and the Holders of the Securities shall be entitled to conclusively
rely upon any order or decree entered by any court of competent jurisdiction in which such

67

 

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 Senior Indebtedness and other indebtedness of the Company, the amount thereof or payable
thereon, the amount or amounts paid or distributed thereon and all other facts pertinent thereto or
to this Article XV.

     Section 15.10 Satisfaction and Discharge; Defeasance and Covenant Defeasance. Subject to Section 15.01, amounts and U.S. Government Obligations deposited in trust with the
Trustee pursuant to and in accordance with Article XII and not, at the time of such deposit,
prohibited to be deposited under Sections 15.02 or 15.03 shall not be subject to this Article XV.

     Section 15.11  Trustee Not Fiduciary for Holders of Senior Indebtedness. With respect to the holders of Senior Indebtedness, the Trustee undertakes to
perform or observe only such of its covenants and obligations as are specifically set forth in this
Article XV, and no implied covenants or obligations with respect to the holders of Senior
Indebtedness shall be read into this Indenture against the Trustee. The Trustee, shall not be
deemed to owe any fiduciary duty to the holders of Senior Indebtedness. The Trustee shall not be
liable to any such holder if it shall pay over or distribute to or on behalf of Holders of
Securities or the Company, or any other Person, moneys or assets to which any holder of Senior
Indebtedness shall be entitled by virtue of this Article XV or
otherwise.

opinion or representations with respect to the accounting matters upon which his or her
certificate, statement or opinion may be based are erroneous. Any certificate or opinion of any
firm of independent registered public accountants filed with the Trustee shall contain a statement
that such firm is independent.

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

          (f) Where any Person is required to make, give or execute two or more applications, requests,
consents, certificates, statements, opinions or other instruments under this Indenture, they may,
but need not, be consolidated and form one instrument.

     Section 16.02 Trust Indenture Act Controls. If and to the extent that any provision of this Indenture limits, qualifies or conflicts with
the duties imposed by, or another provision included in this Indenture which is required to be
included in this Indenture by any of the provisions of Sections 310 to 318, inclusive, of the Trust
Indenture Act, such imposed duties or incorporated provision shall control.

     Section 16.03 Notices to the Company and Trustee. Any notice or demand authorized by this Indenture shall be effective only upon actual receipt.
Any such notice or demand to be made upon, given or furnished to, or filed with, the Company or the
Trustee shall be sufficiently made, given, furnished or filed for all purposes if it shall be
mailed, delivered or telefaxed to:

69

 

          (a) the Company, at 1500 Corporate Drive, Suite 400, Canonsburg, Pennsylvania 153717,
Attention: General Counsel, fax: (724) 514-1870, or at such other address or facsimile number as
may have been furnished in writing to the Trustee by the Company.

          (b) the Trustee, at the Corporate Trust Office of the Trustee, Attention: Mylan Laboratories
Inc. Administrator.

Any such notice, demand or other document shall be in the English language.

     Section 16.04 Notices to Securityholders; Waiver. Any notice required or permitted to be given to Securityholders shall be sufficiently given
(unless otherwise herein expressly provided),

          (a) if to Holders, if given in writing by first class mail, postage prepaid, to such Holders
at their addresses as the same shall appear on the Register of the Company.

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

          (c) 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 on such waiver. 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 that is mailed
in the manner herein provided shall be conclusively presumed to have been duly given. In any case
where notice to Holders is given by publication, any defect in any notice so published as to any
particular Holder shall not affect the sufficiency of such notice with respect to other Holders,
and any notice that is published in the manner herein provided shall be conclusively presumed to
have been duly given.

     Section 16.05 Legal Holiday. Unless otherwise specified pursuant to Section 3.01, in any case where any Interest Payment
Date, Redemption Date or Maturity of any Security of any series shall not be a Business Day at any
Place of Payment for the Securities of that series, then payment of principal and premium, if any,
or interest need not be made at such Place of Payment on such date, but may be made on the next
succeeding Business Day at such Place of Payment with the same force and effect as if made on such
Interest Payment Date, Redemption Date or Maturity and no interest shall accrue on such payment for
the period from and after such Interest Payment Date, Redemption Date or Maturity, as the case may
be, to such Business Day if such payment is made or duly provided for on such Business Day.

     Section 16.06 Effects 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.

70

 

     Section 16.07 Successors and Assigns. All covenants and agreements in this Indenture by the parties hereto shall bind their respective
successors and assigns and inure to the benefit of their permitted successors and assigns, whether

     Section 16.08 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 16.09 Benefits of Indenture. Nothing in this Indenture expressed and nothing that may be implied from any of the provisions
hereof is intended, or shall be construed, to confer upon, or to give to, any Person or corporation
other than the parties hereto and their successors and the Holders of the Securities any benefit or
any right, remedy or claim under or by reason of this Indenture or any covenant, condition,
stipulation, promise or agreement hereof, and all covenants, conditions, stipulations, promises and
agreements in this Indenture contained shall be for the sole and exclusive benefit of the parties
hereto and their successors and of the Holders of the Securities.

     Section 16.10 Counterparts Originals. This Indenture may be executed in any number of counterparts, each of which so executed shall be
deemed to be an original, but all such counterparts shall together constitute but one and the same
instrument.

     Section 16.11 Governing Law; Waiver of Trial by Jury. This Indenture and the Securities shall be deemed to be contracts made under the law of the
State of New York, and for all purposes shall be governed by and construed in accordance with the
law of said State.

     EACH PARTY HERETO, AND EACH HOLDER OF A SECURITY BY ACCEPTANCE THEREOF, HEREBY WAIVES, TO THE
FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF
ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF, UNDER OR IN CONNECTION WITH THIS INDENTURE.

the Underwriters shall be issued in the form of one or more Global Securities, which shall be
deposited on behalf of the purchasers of the Securities represented thereby with The Bank of New
York, at its Corporate Trust Office, as custodian for the depositary, The Depository Trust Company
(“DTC”, and such depositary, or any successor thereto, being hereinafter referred to as the
“Depositary”), and registered in the name of its nominee, Cede & Co. (or any successor thereto),
for the accounts of participants in the Depositary, duly executed by the Company and authenticated
by the Trustee as hereinafter provided. The aggregate principal amount of the Global Securities
may from time to time be increased or decreased by adjustments made on the

11

 

records of the Securities Custodian as hereinafter provided, subject in each case to
compliance with the Applicable Procedures.

     (b) Global Securities In General. The Global Security shall represent such of the
outstanding Securities as shall be specified therein and each shall provide that it shall represent
the aggregate principal amount of outstanding Securities from time to time endorsed thereon and
that the aggregate principal amount of outstanding Securities represented thereby may from time to
time be reduced or increased, as appropriate, to reflect exchanges, purchases or conversions of
such Securities.

     Members of, or participants in, the Depositary (“Agent Members”) shall have no rights
under this Indenture with respect to any Global Security held on their behalf by the Depositary or
under the Global Security, and the Depositary (including, for this purpose, its nominee) may be
treated by the Company, the Trustee and any agent of the Company or the Trustee as the absolute
owner and Holder of such Global Security for all purposes whatsoever. None of the Trustee, the
Paying Agent or the Security Registrar shall have any responsibility or obligation to any
beneficial owner in a Global Security, an Agent Member or other Person with respect to the accuracy
of the records of the Depositary or its nominee or of any Agent Member, with respect to any
ownership interest in the Securities or with respect to the delivery to any Agent Member,
beneficial owner or other Person (other than the Depositary) of any notice (including any notice of
redemption) or the payment of any amount, under or with respect to such Securities. All notices
and communications to be given to the Holders and all payments to be made to Holders under the
Securities and this Indenture shall be given or made only to or upon the order of the registered
Holders (which shall be the Depositary or its nominee in the case of the Global Security). The
rights of beneficial owners in the Global Security shall be exercised only through the Depositary
subject to the applicable procedures. The Trustee, the Paying Agent and the Security Registrar
shall be entitled to rely and shall be fully protected in relying upon information furnished by the
Depositary with respect to its members, participants and any beneficial owners. The Trustee, the
Paying Agent and the Security Registrar shall be entitled to deal with the Depositary, and any
nominee thereof, that is the registered Holder of any Global Security for all purposes of this
Indenture relating to such Global Security (including the payment of principal, premium, if any,
and interest and additional amounts, if any, and the giving of instructions or directions by or to
the owner or Holder of a beneficial ownership interest in such Global Security) as the sole Holder
of such Global Security and shall have no obligations to the beneficial owners thereof. None of
the Trustee, the Paying Agent or the Security Registrar shall have any responsibility or liability
for any acts or omissions of the Depositary with respect to such Global Security, for the records
of any such depositary, including records in respect of beneficial ownership interests in respect
of any such Global Security, for any transactions between the Depositary and any Agent Member or
between or among the Depositary, any such Agent Member and/or any Holder or owner of a beneficial
interest in such Global Security, or for any transfers of beneficial interests in any such Global
Security.

     Notwithstanding the foregoing, nothing herein shall (1) 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 the Depositary or (2) impair, as between the Depositary and its
Agent Members, the operation of customary practices governing the exercise of the rights of a
Holder of any Security.

     (c) Book Entry Provisions. The Company shall execute and the Trustee shall, in
accordance with this Section 2.01(c), authenticate and deliver initially one or more Global
Securities that (1) shall be registered in the name of the Depositary or its nominee, (2) shall be
delivered by the Trustee to the Depositary or pursuant to the Depositary’s instructions and (3)
shall bear legends substantially to the following effect:

12

 

     “UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY
TRUST COMPANY TO THE COMPANY OR ITS AGENT FOR REGISTRATION OF TRANSFER, EXCHANGE OR PAYMENT, AND
ANY CERTIFICATE ISSUED IS REGISTERED IN THE NAME OF CEDE & CO. OR IN SUCH OTHER NAME AS IS
REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY (AND ANY PAYMENT HEREON
IS MADE TO CEDE & CO. OR TO SUCH OTHER ENTITY AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF
THE DEPOSITORY TRUST COMPANY), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY
OR TO ANY PERSON IS WRONGFUL SINCE THE REGISTERED OWNER HEREOF, CEDE & CO., HAS AN INTEREST HEREIN.
THIS SECURITY IS A GLOBAL SECURITY WITHIN THE MEANING OF THE INDENTURE HEREINAFTER REFERRED TO AND
IS REGISTERED IN THE NAME OF A DEPOSITARY OR A NOMINEE THEREOF. THIS SECURITY IS EXCHANGEABLE FOR
SECURITIES REGISTERED IN THE NAME OF A PERSON OTHER THAN THE DEPOSITARY OR ITS NOMINEE ONLY IN THE
LIMITED CIRCUMSTANCES DESCRIBED IN THE INDENTURE AND, UNLESS AND UNTIL IT IS EXCHANGED IN WHOLE OR
IN PART FOR SECURITIES IN DEFINITIVE FORM, THIS SECURITY MAY NOT BE TRANSFERRED EXCEPT AS A WHOLE
BY THE DEPOSITARY TO A NOMINEE OF THE DEPOSITARY OR BY A NOMINEE OF THE DEPOSITARY TO THE
DEPOSITARY OR ANOTHER NOMINEE OF THE DEPOSITARY OR BY THE DEPOSITARY OR ANY SUCH NOMINEE TO A
SUCCESSOR DEPOSITARY OR A NOMINEE OF SUCH SUCCESSOR DEPOSITARY.”

     Section 2.02. Execution and Authentication.

     (a) The aggregate principal amount of Securities which may be authenticated and delivered
under this Indenture is limited to $___aggregate principal amount ($___aggregate
principal amount if the Underwriters exercise their over-allotment option in full), except as
provided in Sections 2.07 and 2.08.

     (b) The Securities shall be executed on behalf of the Company by one of its Officers. The
signatures of any of the Officers on the Securities may be manual or facsimile.

     (c) 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.

     (d) No Security or Guarantee endorsed thereon 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 duly executed by the
Trustee by manual signature of an authorized signatory, and such certificate upon any Security
shall be conclusive evidence, and the only evidence, that such Security has been duly authenticated
and delivered hereunder and is entitled to the benefits of this Indenture.

     (e) The Trustee shall authenticate and make available for delivery Securities for original
issue in the aggregate principal amount of $___(or up to $___if the Underwriters
exercise their over-allotment option in full) upon receipt of a Company Order. The Company Order
shall specify the amount of Securities to be authenticated, shall provide that all

13

 

such Securities will be represented by a Global Security and the date on which each original
issue of Securities is to be authenticated.

     (f) The Trustee shall act as the initial authenticating agent. Thereafter, the Trustee may
appoint an authenticating agent acceptable to the Company to authenticate Securities. An
authenticating agent may authenticate Securities whenever the Trustee may do so. Each reference in
this Indenture to authentication by the Trustee includes authentication by such agent. An
authenticating agent shall have the same rights as an Agent to deal with the Company or an
Affiliate of the Company.

     (g) The Securities shall be issuable only in registered form without coupons and only in
denominations of $1,000 principal amount and any integral multiple thereof.

     Section 2.03. Registrar, Paying Agent and Conversion Agent.

     (a) The Company shall maintain one or more offices or agencies where Securities may be
presented for registration of transfer or for exchange (each, a “Registrar”), one or more offices
or agencies where Securities may be presented or surrendered for payment (each, a “Paying Agent”),
one or more offices or agencies where Securities may be presented for conversion (each, a
“Conversion Agent”) and one or more offices or agencies where notices and demands to or upon the
Company in respect of the Securities and this Indenture may be served. The Company will at all
times maintain a Paying Agent, Conversion Agent, Registrar and an office or agency where notices
and demands to or upon the Company in respect of the Securities and this Indenture may be served in
the Borough of Manhattan, The City of New York. One of the Registrars (the “Primary Registrar”)
shall keep a register of the Securities and of their transfer and exchange. At the option of the
Company, any payment of cash may be made by check mailed to the Holders at their addresses set
forth in the register of Holders.

     (b) The Company shall enter into an appropriate agency agreement with any Agent not a party to
this Indenture, provided that the Agent may be an Affiliate of the Trustee. The agreement shall
implement the provisions of this Indenture that relate to such Agent. The Company shall notify the
Trustee of the name and address, and any change in the name or address, of any Agent not a party to
this Indenture. If the Company fails to maintain a Registrar, Paying Agent, Conversion Agent, or
agent for service of notices and demands in any place required by this Indenture, or fails to give
the foregoing notice, the Trustee shall act as such. The Company or any Affiliate of the Company
may act as Paying Agent (except for the purposes of Article 9).

     (c) The Company hereby initially designates The Bank of New York as Paying Agent, Registrar,
Securities Custodian and Conversion Agent, and designates the Corporate Trust Office of the Trustee
as the office or agency of the Company for each of the aforesaid purposes and as the office or
agency where notices and demands to or upon the Company in respect of the Securities and this
Indenture may be served.

     Section 2.04. Paying Agent To Hold Money In Trust.

     Unless otherwise specified herein, prior to 10:00 a.m., New York City time, on each due
date of the payment of principal of, or interest on, any Securities, the Company shall deposit a
sum sufficient to

14

 

pay such principal or interest so becoming due. A Paying Agent shall hold in trust for the
benefit of Holders of Securities or the Trustee all money held by the Paying Agent for the payment
of principal of, or interest on, the Securities, and shall notify the Trustee of any failure by the
Company (or any other obligor on the Securities) to make any such payment. If the Company or an
Affiliate of the Company acts as Paying Agent, it shall, before 10:00 a.m., New York City time, on
each due date of the principal of, or interest on, any Securities, segregate the money and hold it
as a separate trust fund for the benefit of Holders. The Company at any time may require a Paying
Agent to pay all money held by it to the Trustee, and the Trustee may at any time during the
continuance of any Default, upon written request to a Paying Agent, require such Paying Agent to
pay forthwith to the Trustee all sums so held in trust by such Paying Agent. Upon doing so, the
Paying Agent (other than the Company) shall have no further liability for the money.

     Any money deposited with the Trustee or any Paying Agent, or then held by the Company, in
trust for the payment of the principal of or interest on any Security and remaining unclaimed for
two years after such principal or interest has become due and payable shall promptly be paid to the
Company 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 Company for
payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust
money, and all liability of the Company as trustee thereof, shall thereupon cease; provided,
however, that the Trustee or such Paying Agent, before being required to make any such repayment,
may at the expense of the Company cause to be published once, in a newspaper published in the
English language, customarily published on each Business Day and of general circulation in The City
of New York, notice that such money remains unclaimed and that, after a date specified therein,
which shall not be less than 30 days from the date of such publication, any unclaimed balance of
such money then remaining will promptly be repaid to the Company.

     Section 2.05. Conversion Agent To Hold Money In Trust.

     The Company shall require each Conversion Agent (that is not the Trustee) to agree in
writing that the Conversion Agent will hold in trust for the benefit of Holders or the Trustee all
cash and shares of Common Stock delivered by the Company to the Conversion Agent for the delivery
of amounts due upon conversion, and will notify the Trustee of any default by the Company in making
any such delivery.

     While any such default continues, the Trustee may require a Conversion Agent to deliver all
cash and shares of Common Stock delivered by the Company to it to the Trustee. Upon payment over to
the Trustee, the Conversion Agent (if other than the Company or a Subsidiary) shall have no further
liability in respect of such amounts. If the Company or a Subsidiary acts as Conversion Agent, it
shall segregate and hold in a separate trust fund for the benefit of the Holders all cash and
shares of Common Stock held by it as Conversion Agent. Upon any bankruptcy or reorganization
proceedings relating to the Company, the Trustee shall serve as Conversion Agent for the
Securities.

     Section 2.06. Lists of Holders of Securities.

     The Trustee shall preserve in as current a form as is reasonably practicable the most
recent list available to it of the names and addresses of Holders of Securities. The Company shall
furnish or cause the Registrar to furnish to the Trustee (a) semiannually, not more than 10 days
after each Regular Record Date, a list, in such form as the Trustee may reasonably require, of the
names and addresses of the Holders as of such Regular Record Date; and (b) at such other times as
the Trustee may request in writing, within 30 days after receipt by the Company of any such
request, a list of similar form and content to that in subsection (a) hereof as of a date not more
than 15 days prior to the time such list is

15

 

furnished; provided, however, that if and so long as the Trustee shall be the Primary
Registrar, no such list need be furnished.

     Section 2.07. Transfer and Exchange.

     (a) Subject to compliance with any applicable additional requirements contained in Section
2.13, when a Security is presented to a Registrar with a request to register a transfer thereof or
to exchange such Security for an equal principal amount of Securities of other authorized
denominations, the Registrar shall register the transfer or make the exchange as requested if its
requirements for such transactions are met; provided, however, that every Security presented or
surrendered for registration of transfer or exchange shall be duly endorsed or accompanied by an
assignment form and, if applicable, a transfer certificate each substantially in the form included
in Exhibit A, and completed in a manner satisfactory to the Registrar and duly executed by the
Holder thereof or its attorney duly authorized in writing. To permit registration of transfers and
exchanges, upon surrender of any Security for registration of transfer or exchange at an office or
agency maintained pursuant to Section 2.03, the Company shall execute and the Trustee shall
authenticate Securities of a like aggregate principal amount at the Registrar’s request. Any
exchange or transfer shall be without charge, except that the Company or the Registrar may require
payment of a sum sufficient to cover any transfer tax or similar governmental charge that may be
imposed in relation thereto; provided that this sentence shall not apply to any exchange pursuant
to Section 2.11, 2.13(a), 4.02(d) or 10.06.

     (b) Neither the Company, any Registrar nor the Trustee shall be required to register the
transfer of or exchange any Securities or portions thereof in respect of which a Fundamental Change
Purchase Notice has been delivered and not withdrawn by the Holder thereof (except, in the case of
the purchase of a Security in part, the portion thereof not to be purchased).

     (c) All Securities issued upon any transfer or exchange of Securities shall be 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.

     (d) Any Registrar appointed pursuant to Section 2.03 shall provide to the Trustee such
information as the Trustee may reasonably require in connection with the delivery by such Registrar
of Securities upon transfer or exchange of Securities.

     (e) Each Holder of a Security agrees to indemnify the Company and the Trustee against any
liability that may result from the registration of transfer, exchange or assignment of such
Holder’s Security in violation of any provision of this Indenture and/or applicable United States
federal or state securities law.

     (f) The Trustee shall have no obligation or duty to monitor, determine or inquire as to
compliance with any restrictions on transfer imposed under this Indenture or under applicable law
with respect to any transfer of any interest in any Security (including any transfers between or
among Agent Members or other beneficial owners of interests in any Global Security) other than to
require delivery of such certificates and other documentation or evidence as are expressly required
by, and to do so if and when expressly required by the terms of, this Indenture, and to examine the
same to determine substantial compliance as to form with the express requirements hereof.

16

 

     Section 2.08. Replacement Securities.

     (a) If (1) any mutilated Security is surrendered to the Trustee, or (2) the Company and the
Trustee receive evidence to their satisfaction of the destruction, loss or theft of any Security,
and there is delivered to the Company and the Trustee, such security or indemnity, in each case, as
may be required by them to save each of them harmless, then, in the absence of notice to the
Company or the Trustee that such Security has been acquired by a protected purchaser, the Company
shall execute and upon a Company Request the Trustee shall authenticate and deliver, in exchange
for any such mutilated Security or in lieu of any such destroyed, lost or stolen Security, a
replacement Security of like tenor and principal amount, bearing a number not contemporaneously
outstanding and each Guarantor shall execute a replacement Guarantee.

     (b) If any such mutilated, destroyed, lost or stolen Security has become or is about to become
due and payable, or is about to be purchased by the Company pursuant to Article 3, or converted
pursuant to Article 4, the Company in its discretion may, instead of issuing a new Security, pay,
purchase or convert such Security, as the case may be.

     (c) Upon the issuance of any new Securities under this Section 2.08, 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 counsel and the
Trustee) in connection therewith.

     (d) Every new Security and Guarantee issued pursuant to this Section 2.08 in lieu of any
mutilated, destroyed, lost or stolen Security shall constitute an original additional contractual
obligation of the Company and each Guarantor, whether or not the mutilated, destroyed, lost or
stolen Security shall be at any time enforceable by anyone, and shall be entitled to all benefits
of this Indenture equally and proportionately with any and all other Securities duly issued
hereunder.

     (e) The provisions of this Section 2.08 are (to the extent lawful) exclusive and shall
preclude (to the extent lawful) all other rights and remedies with respect to the replacement or
payment of mutilated, destroyed, lost or stolen Securities.

     Section 2.09. Outstanding Securities.

     (a) Securities outstanding (“Outstanding”) at any time are all Securities authenticated by the
Trustee, except for those canceled by it, those purchased pursuant to Article 3, those converted
pursuant to Article 4, those delivered to the Trustee for cancellation or surrendered for transfer
or exchange and those described in this Section 2.09 as not Outstanding.

     (b) If a Security is replaced pursuant to Section 2.08, such replaced Security ceases to be
Outstanding unless the Company receives proof satisfactory to it that the replaced Security is held
by a protected purchaser.

     (c) If a Paying Agent holds in respect of the Outstanding Securities on a Fundamental Change
Purchase Date or the Final Maturity Date money sufficient to pay the principal of and accrued
interest on Securities (or portions thereof) payable on that date, then on and after such

17

 

Fundamental Change Purchase Date or Final Maturity Date, as the case may be, such Securities
(or portions thereof, as the case may be) shall cease to be Outstanding and interest on them shall
cease to accrue.

     (d) Subject to the restrictions contained in Section 2.10, a Security does not cease to be
Outstanding because the Company or an Affiliate of the Company holds the Security.

     Section 2.10. Treasury Securities.

     In determining whether the Holders of the required principal amount of Securities have
concurred in any request, demand, authorization, notice, direction, waiver or consent, Securities
owned by the Company or any other obligor on the Securities or by any Affiliate of the Company or
of such other obligor shall be disregarded, except that, for purposes of determining whether the
Trustee shall be protected in relying on any such request, demand, authorization, notice,
direction, waiver or consent, only Securities which a Trust Officer of the Trustee actually knows
are so owned shall be so disregarded.

     Section 2.11. Temporary Securities.

     Until definitive Securities are ready for delivery, the Company may prepare and execute,
and, upon receipt of a Company Order, the Trustee shall authenticate and deliver, temporary
Securities. Temporary Securities shall be substantially in the form of definitive Securities but
may have variations that the Company with the consent of the Trustee considers appropriate for
temporary Securities. Without unreasonable delay, the Company shall prepare and the Trustee shall
authenticate and deliver definitive Securities in exchange for temporary Securities representing an
equal principal amount of Securities. The temporary Securities will be exchanged for definitive
Securities in accordance with Sections 2.07 and 2.13 hereof. Until so exchanged, temporary
Securities shall have the same rights under this Indenture as the definitive Securities.

     Section 2.12. Cancellation.

     The Company at any time may deliver Securities to the Trustee for cancellation. The
Registrar, the Paying Agent and the Conversion Agent shall forward to the Trustee any Securities
surrendered to them for transfer, exchange, purchase, payment or conversion. The Trustee and no one
else shall cancel, in accordance with its standard procedures, all Securities surrendered for
transfer, exchange, purchase, payment, conversion or cancellation and shall dispose of the
cancelled Securities in accordance with its customary procedures or deliver the canceled Securities
to the Company upon request. All Securities which are purchased or otherwise acquired by the
Company or any of its Subsidiaries prior to the Final Maturity Date pursuant to Article 3 shall be
delivered to the Trustee for cancellation, and the Company may not hold or resell such Securities
or issue any new Securities to replace any such Securities or any Securities that any Holder has
converted pursuant to Article 4. The Trustee shall maintain a record of all canceled Securities.
The Trustee shall provide the Company a list of all Securities that have been canceled from time to
time as requested by the Company in writing.

     Section 2.13. Legend; Additional Transfer and Exchange Requirements.

     (a) A Global Security may not be transferred, in whole or in part, to any Person other than
the Depositary or a nominee or any successor thereof, and no such transfer to any such other Person
may be registered; provided that the foregoing shall not prohibit any transfer of a Security that
is issued in exchange for a Global Security but is not itself a Global Security. No transfer of a
Security to any Person shall be effective under this Indenture or the Securities unless and until

18

 

such Security has been registered in the name of such Person. Notwithstanding any other
provisions of this Indenture or the Securities, transfers of a Global Security, in whole or in
part, shall be made only in accordance with this Section 2.13.

     (b) The provisions below shall apply only to Global Securities:

     (1) Each Global Security authenticated under this Indenture shall be registered in the
name of the Depositary 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 purposes of this Indenture.

     (2) Notwithstanding any other provisions of this Indenture or the Securities, a Global
Security shall not be exchanged in whole or in part for a Security registered, and no
transfer of a Global Security in whole or in part shall be registered in the name of any
Person other than the Depositary or one or more nominees thereof; provided that a Global
Security may be exchanged for Securities registered in the names of any person designated by
the Depositary in the event that (A) the Depositary has notified the Company that it is
unwilling or unable to continue as Depositary for such Global Security or such Depositary
has ceased to be a “clearing agency” registered under the Exchange Act, and in either case a
successor Depositary is not appointed by the Company within 90 days after receiving such
notice or becoming aware that the Depositary has ceased to be a “clearing agency,” (B) an
Event of Default has occurred and is continuing with respect to the Securities or (C) the
Company executes and delivers to the Trustee and the Primary Registrar an Officer’s
Certificate stating that such Global Security shall be so exchangeable. Any Global Security
exchanged pursuant to the preceding sentence shall be so exchanged as directed by the
Depositary. Any Security issued in exchange for a Global Security or any portion thereof
shall be a Global Security; provided, however, that any such Security so issued that is
registered in the name of a Person other than the Depositary or a nominee thereof shall not
be a Global Security.

     (3) Securities issued in exchange for a Global Security or any portion thereof that are
not issued as a Global Security shall be issued in definitive, fully registered form,
without interest coupons, shall have a principal amount equal to that of such Global
Security or portion thereof to be so exchanged, shall be registered in such names and be in
such authorized denominations as the Depositary shall designate and shall bear the
applicable legends provided for herein. Any Global Security to be exchanged in whole shall
be surrendered by the Depositary to the Trustee or the Registrar. With regard to any Global
Security to be exchanged in part, either such Global Security shall be so surrendered for
exchange or, if the Trustee is acting as custodian for the Depositary or its nominee with
respect to such Global Security, the principal amount thereof shall be reduced, by an amount
equal to the portion thereof to be so exchanged, by means of an appropriate adjustment made
on the records of the Trustee. Upon any such surrender or adjustment, the Trustee shall
authenticate and deliver the Security issuable on such exchange to or upon the order of the
Depositary or an authorized representative thereof.

     (4) Subject to clause (6) of this Section 2.13(b), the registered Holder may grant
proxies and otherwise authorize any Person, including Agent Members and Persons

19

 

that may hold interests through Agent Members, to take any action which a Holder is
entitled to take under this Indenture or the Securities.

     (5) In the event of the occurrence of any of the events specified in clause (2) of this
Section 2.13(b), the Company will promptly make available to the Trustee a reasonable supply
of Certificated Securities in definitive, fully registered form, without interest coupons.

     (6) Neither Agent Members nor any other Persons on whose behalf Agent Members may act
shall have any rights under this Indenture with respect to any Global Security registered in
the name of the Depositary or any nominee thereof, or under any such Global Security, and
the Depositary or such nominee, as the case may be, may be treated by the Company, the
Trustee and any agent of the Company, the Trustee and any agent of the Company or the
Trustee as the absolute owner and Holder of such Global Security for all purposes
whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Company, the
Trustee or any agent of the Company or the Trustee from giving effect to any written
certification, proxy or other authorization furnished by the Depositary or such nominee, as
the case may be, or impair, as between the Depositary, its Agent Members and any other
Person on whose behalf an Agent Member may act, the operation of customary practices of such
Persons governing the exercise of the rights of a Holder of any Security.

     (7) At such time as all interests in a Global Security have been converted, cancelled
or exchanged for Securities in certificated form, such Global Security shall, upon receipt
thereof, be cancelled by the Trustee in accordance with standing procedures and instructions
existing between the Depositary and the Securities Custodian, subject to Section 2.12 of
this Indenture. At any time prior to such cancellation, if any interest in a Global Security
is converted, canceled or exchanged for Securities in certificated form, the principal
amount of such Global Security shall, in accordance with the standing procedures and
instructions existing between the Depositary and the Securities Custodian, be appropriately
reduced, and an endorsement shall be made on such Global Security, by the Trustee or the
Securities Custodian, at the direction of the Trustee, to reflect such reduction.

     Section 2.14. CUSIP Numbers.

     The Company in issuing the Securities may use one or more “CUSIP,” “ISIN” or other
similar numbers (if then generally in use), and, if so, the Trustee shall use “CUSIP,” “ISIN” or
other similar numbers in a Fundamental Change Purchase Notice 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 Fundamental Change Purchase Notice and
that reliance may be placed only on the other identification numbers printed on the Securities, and
any such purchase shall not be affected by any defect in or omission of such numbers. The Company
will notify the Trustee in writing of any change in the “CUSIP,” “ISIN” or other similar numbers.

20

 

     Section 2.15. Calculations.

     Except as otherwise specifically stated herein or in the Securities, all calculations to
be made in respect of the Securities shall be the obligation of the Company. All calculations made
by the Company or its agent as contemplated pursuant to the terms hereof and of the Securities
shall be made in good faith and be final and binding on the Holders absent manifest error. The
Company shall provide a schedule of calculations to the Trustee, and the Trustee shall be entitled
to rely upon the accuracy of the calculations by the Company without independent verification. The
Trustee shall forward calculations made by the Company to any Holder of Securities upon request.

     Section 2.16. Payment of Interest; Interest Rights Preserved.

     Interest on any Security which is payable, and is punctually paid or duly provided for,
on the Stated Maturity of such interest shall be paid to the Person in whose name the Security is
registered at the close of business on the Regular Record Date for such interest payment.

     Any interest on any Security which is payable, but is not punctually paid or duly provided
for, on the Stated Maturity of such interest, and interest on such defaulted interest at the then
applicable interest rate borne by the Securities, to the extent lawful (such defaulted interest and
interest thereon herein collectively called “Defaulted Interest”), shall forthwith cease to be
payable to the Holder on the Regular Record Date; and such Defaulted Interest may be paid by the
Company, at its election in each case, as provided in Subsection (a) or (b) below:

     (a) The Company may elect to make payment of any Defaulted Interest to the Persons in
whose names the Securities are registered at the close of business on a Special Record Date for the
payment of such Defaulted Interest, which shall be fixed in the following manner. The Company shall
notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each
Security and the date (not less than 20 days after such notice) of the proposed payment (the
“Special Payment Date”), and on the date of payment 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
Special Payment Date, such money when deposited to be held in trust for the benefit of the Persons
entitled to such Defaulted Interest as in this subsection provided. Thereupon the Trustee shall fix
a Special Record Date for the payment of such Defaulted Interest which shall be not more than 15
days and not less than 10 days prior to the date of the Special Payment Date and not less than 10
days after the receipt by the Trustee of the notice of the proposed payment. The Trustee shall
promptly notify the Company in writing of such Special Record Date. Unless the Company issues a
press release to the same effect, in the name and at the expense of the Company, the Trustee shall
cause notice of the proposed payment of such Defaulted Interest and the Special Record Date
therefor to be mailed, first-class postage prepaid, to each Holder at its address as it appears in
the Security Register, not less than 10 days prior to such Special Record Date or notify in such
other manner as the Trustee determines, including in accordance with any Applicable Procedures.
Notice of the proposed payment of such Defaulted Interest and the Special Record Date and Special
Payment Date therefor having been so mailed or otherwise conveyed, such Defaulted Interest shall be
paid to the Persons in whose names the Securities are registered on such Special Record Date and
shall no longer be payable pursuant to the following paragraph (b).

21

 

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

     Subject to the foregoing provisions of this Section 2.16, each Security delivered under
this Indenture upon registration of transfer of or in exchange for or in lieu of any other Security
shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such
other Security.

     Section 2.17. Computation of Interest.

     Interest on the Securities shall be computed on the basis of a 360-day year comprised of
twelve 30-day months.

ARTICLE 3

PURCHASE

     Section 3.01. Purchase of Securities by the Company for Cash at Option of the Holder Upon
a Fundamental Change.

     (a) If a Fundamental Change occurs prior to the Final Maturity Date, each Holder of a Security
shall have the right, at the option of the Holder, to require the Company to purchase for cash in
whole or in part (in principal amounts of $1,000 and integral multiples thereof) the Securities of
such Holder at the Fundamental Change Purchase Price on the date specified by the Company that is
not less than 30 days and not more than 45 days after the Fundamental Change Effective Date (the
“Fundamental Change Purchase Date”).

     (b) Not less than 10 Business Days prior to the date that is anticipated to be the Fundamental
Change Effective Date, the Company shall mail a written notice of the Fundamental Change and of the
resulting purchase right to the Trustee, Paying Agent and to each Holder of record of Securities
(an “Issuer Fundamental Change Notice”). The Issuer Fundamental Change Notice shall include the
form of a Fundamental Change Purchase Notice (defined below) to be completed by the Holder and
shall state:

     (1) the events causing such Fundamental Change;

     (2) the date (or expected date) of such Fundamental Change;

     (3) the last date by which the Fundamental Change Purchase Notice must be delivered to
elect the purchase option pursuant to this Section 3.01;

     (4) the Fundamental Change Purchase Date;

     (5) the Fundamental Change Purchase Price;

     (6) the Holder’s right to require the Company to purchase the Securities;

22

 

     (7) the name and address of each Paying Agent and Conversion Agent;

     (8) the then effective Conversion Rate and any adjustments to the Conversion Rate
resulting from such Fundamental Change;

     (9) the procedures that the Holder must follow to exercise rights under Article 4 of
this Indenture and that the Securities as to which a Fundamental Change Purchase Notice has
been given may be converted into Common Stock pursuant to Article 4 of this Indenture only
to the extent that the Fundamental Change Purchase Notice has been withdrawn in accordance
with the terms of this Indenture;

     (10) the procedures that the Holder must follow to exercise rights under this Section
3.01;

     (11) the procedures for withdrawing a Fundamental Change Purchase Notice;

     (12) that, unless the Company fails to pay such Fundamental Change Purchase Price,
Securities covered by any Fundamental Change Purchase Notice will cease to be outstanding
and interest will cease to accrue on and after the Fundamental Change Purchase Date; and

     (13) the CUSIP, ISIN or other similar number of the Securities.

     At the Company’s written request, the Trustee shall give such Issuer Fundamental Change
Notice in the Company’s name and at the Company’s expense; provided that, in all cases, the text of
such Issuer Fundamental Change Notice shall be prepared by the Company. In connection with the
delivery of the Issuer Fundamental Change Notice to the Holders, the Company shall publish a notice
containing substantially the same information that is required in the Issuer Fundamental Change
Notice in a newspaper of general circulation in the City of New York or publish information on a
website of the Company or through such other public medium the Company may use at that time. If any
of the Securities is in the form of a Global Security, then the Company shall modify such notice to
the extent necessary to accord with the Applicable Procedures relating to the purchase of Global
Securities.

     (c) A Holder may exercise its rights specified in Section 3.01(a) upon delivery of a
written notice (which shall be in substantially the form set forth in the form of Security attached
as Exhibit A under the heading “Fundamental Change Purchase Notice” and which may be delivered by
letter, overnight courier, hand delivery, facsimile transmission or in any other written form and,
in the case of Global Securities, may be delivered electronically or by other means in accordance
with the Depositary’s Applicable Procedures) of the exercise of such rights (a “Fundamental Change
Purchase Notice”) to the Paying Agent at any time prior to the close of business on the Business
Day immediately preceding the Fundamental Change Purchase Date, subject to extension to comply with
applicable law.

     (1) The Fundamental Change Purchase Notice shall state: (A) if the Securities are in
certificated form, the certificate numbers of the Securities which the Holder will deliver
to be purchased (or, if the Security is held in global form, any other items required to
comply with the Applicable Procedures), (B) the portion of the principal amount of the
Securities which the Holder will deliver to be purchased, which portion must be a

23

 

principal amount of $1,000 or any integral multiple thereof and (C) that such Security
shall be purchased as of the Fundamental Change Purchase Date pursuant to the terms and
conditions specified in the Securities and in this Indenture.

     (2) The delivery of a Security for which a Fundamental Change Purchase Notice has been
timely delivered to any Paying Agent and not validly withdrawn prior to, on or after the
Fundamental Change Purchase Date (together with all necessary endorsements) at the office of
such Paying Agent shall be a condition to the receipt by the Holder of the Fundamental
Change Purchase Price therefor.

     (3) The Company shall only be obliged to purchase, pursuant to this Section 3.01, a
portion of a Security if the principal amount of such portion is $1,000 or an integral
multiple thereof. Provisions of this Indenture that apply to the purchase of all of a
Security also apply to the purchase of such portion of such Security.

     (4) Notwithstanding anything herein to the contrary, any Holder delivering to a Paying
Agent the Fundamental Change Purchase Notice contemplated by this Section 3.01(c) shall have
the right to withdraw such Fundamental Change Purchase Notice in whole or in a portion
thereof that is a principal amount of $1,000 or in an integral multiple thereof at any time
prior to the close of business on the Business Day prior to the Fundamental Change Purchase
Date by delivery of a written notice of withdrawal to the Paying Agent in accordance with
Section 3.02(b).

     (5) A Paying Agent shall promptly notify the Company of the receipt by it of any
Fundamental Change Purchase Notice or written withdrawal thereof.

     (6) Anything herein to the contrary notwithstanding, in the case of Global Securities,
any Fundamental Change Purchase Notice may be delivered or withdrawn and such Securities may
be surrendered or delivered for purchase in accordance with the Applicable Procedures as in
effect from time to time.

     Section 3.02. Effect of Fundamental Change Purchase Notice.

     (a) Upon receipt by any Paying Agent of a properly completed Fundamental Change Purchase
Notice from a Holder, the Holder of the Security in respect of which such Fundamental Change
Purchase Notice was given shall (unless such Fundamental Change Purchase Notice is withdrawn as
specified in Section 3.02(b)) thereafter be entitled to receive the Fundamental Change Purchase
Price with respect to such Security. Such Fundamental Change Purchase Price shall be paid to such
Holder promptly following the later of (1) the Fundamental Change Purchase Date (provided that the
conditions in Section 3.01 have been satisfied) and (2) the time of delivery of such Security to a
Paying Agent by the Holder thereof in the manner required by Section 3.01(c). Securities in respect
of which a Fundamental Change Purchase Notice has been given by the Holder thereof may not be
converted in accordance with the provisions of Article 4 on or after the date of the delivery of
such Fundamental Change Purchase Notice unless such Fundamental Change Purchase Notice has first
been validly withdrawn in accordance with Section 3.02(b) with respect to the Securities to be
converted.

24

 

     (b) A Fundamental Change Purchase Notice may be withdrawn by means of a written notice (which
may be delivered by mail, overnight courier, hand delivery, facsimile transmission or in any other
written form and, in the case of Global Securities, may be delivered electronically or by other
means in accordance with the Applicable Procedures) of withdrawal delivered by the Holder to a
Paying Agent at any time prior to the close of business on the Business Day immediately prior to
the Fundamental Change Purchase Date, specifying (1) the principal amount of the Security or
portion thereof (which must be a principal amount of $1,000 or an integral multiple of $1,000 in
excess thereof) with respect to which such notice of withdrawal is being submitted, (2) if the
Securities are in certificated form, the certificate numbers of the Security being withdrawn in
whole or in part and (3) the portion of the principal amount of the Security that will remain
subject to the Fundamental Change Purchase Notice, which portion must be a principal amount of
$1,000 or an integral multiple thereof.

     Section 3.03. Deposit of Fundamental Change Purchase Price.

     (a) On or before 10:00 a.m. New York City time on the applicable Fundamental Change Purchase
Date, the Company shall deposit with the Trustee or with a Paying Agent (or if the Company or an
Affiliate of the Company is acting as the Paying Agent, shall segregate and hold in trust as
provided in Section 2.04) an amount of money (in immediately available funds if deposited on or
after such Fundamental Change Purchase Date), sufficient to pay the aggregate Fundamental Change
Purchase Price of all the Securities or portions thereof that are to be purchased as of the
Fundamental Change Purchase Date.

     (b) If a Paying Agent or the Trustee holds on the Fundamental Change Purchase Date in
accordance with the terms hereof an amount of money sufficient to pay the Fundamental Change
Purchase Price of any Security (or portion thereof) for which a Fundamental Change Purchase Notice
has been tendered and not withdrawn in accordance with this Indenture then, immediately following
the applicable Fundamental Change Purchase Date, whether or not the Security is delivered to the
Paying Agent, such Security shall cease to be outstanding, interest, shall cease to accrue, and the
rights of the Holder in respect of the Security shall terminate (other than the right to receive
the Fundamental Change Purchase Price upon delivery of the Security as aforesaid).

     (c) The Paying Agent will promptly return to the respective Holders thereof any Securities
with respect to which a Fundamental Change Purchase Notice has been withdrawn in compliance with
this Indenture.

     (d) If a Fundamental Change Purchase Date falls after a Regular Record Date and on or before
the related Interest Payment Date, then interest on the Securities payable on such Interest Payment
Date will be payable to the Holders in whose names the Securities are registered at the close of
business on such Regular Record Date.

     Section 3.04. Repayment to the Company.

     To the extent that the aggregate amount of cash deposited by the Company pursuant to
Section 3.03 exceeds the aggregate Fundamental Change Purchase Price of the Securities or portions
thereof that the Company is obligated to purchase, then promptly after the Fundamental Change
Purchase Date the

25

 

Trustee or a Paying Agent, as the case may be, shall return any such excess cash to the
Company, or if such money is then held by the Company in trust, it shall be discharged from the
trust.

     Section 3.05. Securities Purchased In Part.

     Any Security that is to be purchased only in part shall be surrendered at the office of a
Paying Agent, and promptly after the Fundamental Change Purchase Date, as the case may be, 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 such authorized denomination or
denominations as may be requested by such Holder (which must be equal to $1,000 principal amount or
any integral multiple thereof), in aggregate principal amount equal to, and in exchange for, the
portion of the principal amount of the Security so surrendered that is not purchased.

     Section 3.06. Compliance With Securities Laws Upon Purchase of Securities.

     In connection with any offer to purchase Securities under Section 3.01, the Company shall
(a) comply with the provisions of the tender offer rules under the Exchange Act which may then be
applicable, (b) file the related Schedule TO (or any successor or similar schedule, form or report)
if required under the Exchange Act, and (c) otherwise comply with all federal and state securities
laws in connection with such offer to purchase or purchase of Securities, all so as to permit the
rights of the Holders and obligations of the Company under Sections 3.01 through 3.04 to be
exercised in the time and in the manner specified therein. To the extent that compliance with any
such laws, rules and regulations would result in a conflict with any of the terms hereof, this
Indenture is hereby modified to the extent required for the Company to comply with such laws, rules
and regulations.

     Section 3.07. Purchase of Securities In Open Market.

     The Company may purchase Securities in the open market or by tender at any price or
pursuant to private agreements. The Company shall surrender any Security purchased by the Company
pursuant to this Article 3 to the Trustee for cancellation. Any Securities surrendered to the
Trustee for cancellation may not be reissued or resold by the Company and will be canceled promptly
in accordance with Section 2.12.

ARTICLE 4

CONVERSION

     Section 4.01. Conversion Privilege and Conversion Rate.

     (a) Any Security or portion thereof that is an integral multiple of $1,000 principal amount
may be converted by the Holder thereof in accordance with the provisions of this Article 4. Upon
conversion, Holders shall be entitled to receive the amount of cash and, if applicable, shares of
Common Stock determined in the manner provided in Section 4.12. Securities may be converted prior
to the close of business on the third Business Day immediately preceding the Final Maturity Date at
the Conversion Rate in effect at the time of such conversion only under the following
circumstances:

     (1) on any Business Day in any calendar quarter commencing at any time after June 30,
2007, and only during such calendar quarter, if, as of the last day of the immediately
preceding calendar quarter, the Closing Price of the Common Stock for at

26

 

least 20 Trading Days in the period of 30 consecutive Trading Days ending on the last
Trading Day of such preceding calendar quarter was more than 130% of the applicable
Conversion Price on the last day of such preceding calendar quarter;

     (2) on any Business Day during the five Business Day period after any five consecutive
Trading Day period in which the Trading Price per $1,000 principal amount of Securities, as
determined by the Trustee following a request by a Holder in accordance with the procedures
described in Section 4.01(e)(ii), for each Trading Day of that period was less than 98% of
the product of the Closing Price of the Common Stock on such day and the then applicable
Conversion Rate per $1,000 principal amount of Securities.

     (3) if the Company distributes to all holders of Common Stock any rights entitling them
to purchase, for a period expiring within 45 days of distribution, Common Stock, or
securities convertible into Common Stock, at less than, or having a conversion price per
share less than, the Closing Price of the Common Stock on the Trading Day immediately
preceding the declaration date for such distribution;

     (4) if the Company distributes to all holders of Common Stock assets, cash, debt
securities or rights to purchase the Company’s securities, which distribution has a per
share value as determined by the Board of Directors exceeding 15% of the Closing Price per
share of the Common Stock on the Trading Day immediately preceding the declaration date for
such distribution;

     (5) if the Company is a party to any transaction or event (including, but not limited
to, any consolidation, merger or binding share exchange, other than changes resulting from a
subdivision or combination) that is not otherwise a Fundamental Change pursuant to which all
or substantially all shares of the Common Stock would be converted into cash, securities or
other property (provided that the Securities shall not become convertible by reason of a
merger, consolidation or other transaction effected by the Company with one of its direct or
indirect Subsidiaries for the purpose of changing the Company’s state of incorporation or
organization to any other state within the United States or the District of Columbia);

     (6) if a Fundamental Change occurs; or

     (7) at any time during the period beginning on ___, ___and ending at
the close of business on the third Business Day immediately preceding the Final Maturity
Date.

     (b) The Trustee shall have no obligation to determine the Trading Price of the Securities and
whether the Securities are convertible pursuant to clause (2) of Section 4.01(a) unless the Company
has requested such determination and the Company shall have no obligation to make such request
unless a Holder of the Securities provides the Company with reasonable evidence that the Trading
Price per $1,000 principal amount of Securities would be less than 98% of the product of the
Closing Price of the Common Stock and the then applicable Conversion Rate per $1,000 principal
amount of Securities. At such time, the Company shall instruct the Trustee to determine the Trading
Price of the Securities beginning on the next

27

 

Trading Day and on each successive Trading Day until the Trading Price per $1,000 principal
amount of the Securities is greater than 98% of the product of the Closing Price of the Common
Stock and the then applicable Conversion Rate per $1,000 principal amount of the Securities.

     (c) In the case of a distribution contemplated by clause (3) or (4) of Section 4.01(a), the
Company shall notify Holders and the Trustee at least 35 days prior to the ex-dividend date
(defined below) for such distribution (the “Distribution Notice”). Once the Company has given the
Distribution Notice, Holders may surrender their Securities for conversion at any time until the
earlier of the close of business on the Business Day prior to the ex-dividend date or the Company’s
announcement that such distribution will not take place. In the event of a distribution
contemplated by clause (3) or (4) of Section 4.01(a), Holders may not convert the Securities if the
Holders will otherwise participate in such distribution on an as converted basis (assuming for this
purpose that the Securities were convertible solely into a number of shares of Common Stock equal
to the then applicable Conversion Rate). The “ex-dividend date” is the first date upon which a sale
of the Common Stock does not automatically transfer the right to receive the relevant distribution
from the seller of the Common Stock to its buyer. The Company will provide written notice to the
Conversion Agent as soon as reasonably practicable of any anticipated or actual event or
transaction that will cause or causes the Securities to become convertible pursuant to clauses (3)
or (4) of Section 4.01(a).

     (d) In the case of a transaction contemplated by clause (5) of Section 4.01(a), the Company
will notify Holders and the Trustee as promptly as practicable following the date the Company
publicly announces such transaction (but in no event less than 15 days prior to the anticipated
effective date of such transaction). Holders may surrender Securities for conversion at any time
from and after the date which is 15 days prior to the anticipated effective date of such
transaction until the earlier of the date which is 15 days after the actual effective date of such
transaction or the date of the Company’s announcement that such transaction will not take place.

     (e) In the case of a Fundamental Change, the Company shall provide notice thereof (a
“Fundamental Change Conversion Notice”) to the Holders of Securities and the Trustee at least 15
days prior to date that is anticipated to be the Fundamental Change Effective Date. Holders may
surrender Securities for conversion at any time beginning 15 days before the date that is
anticipated to be the Fundamental Change Effective Date until the Trading Day prior to the
Fundamental Change Purchase Date.

     (f) The conversion rights pursuant to this Article 4 shall commence on the Issue Date of the
Securities and expire at the close of business on the third Business Day immediately preceding the
Final Maturity Date, but shall be exercisable only during the time periods specified with respect
to each circumstance pursuant to which the Securities become convertible, subject, in the case of
conversion of any Global Security, to any Applicable Procedures.

     (g) Securities in respect of which a Fundamental Change Purchase Notice has been delivered may
not be surrendered for conversion pursuant to this Article 4 prior to a valid withdrawal of such
Fundamental Change Notice, in accordance with the provisions of Article 3.

     (h) Provisions of this Indenture that apply to conversion of all of a Security also apply to
conversion of a portion of a Security.

28

 

     (i) The Conversion Rate shall be adjusted in certain instances as provided in Section 4.01(j)
and Section 4.06.

     (j) If a Fundamental Change occurs prior to the Final Maturity Date as a result of a
transaction described in clauses (1), (2) or (4) of the definition of the term “Change of Control”
and a Holder elects to convert its Securities “in connection with” such transaction, the Company
shall pay a “Make Whole Premium” by increasing the applicable Conversion Rate for the Securities
surrendered for conversion by a number of additional shares of Common Stock as provided in this
Section 4.01(i) (the “Additional Shares”). A conversion of Securities shall be deemed for these
purposes to be “in connection with” such a transaction if the notice of conversion is received by
the Conversion Agent from and including the Fundamental Change Effective Date and prior to the
close of business on the Business Day prior to the Fundamental Change Purchase Date.

     The number of Additional Shares per $1,000 principal amount of Securities constituting
the Make Whole Premium shall be determined by reference to the table below and shall be based on
the date on which the Fundamental Change Effective Date occurs and the price (the “Stock Price”)
paid, or deemed to be paid, per share of Common Stock in such transaction. If holders of Common
Stock receive only cash in the Fundamental Change transaction, the Stock Price shall be the cash
amount paid per share of Common Stock. Otherwise, the Stock Price shall be the average of the
Closing Prices of the Common Stock for each of the ten consecutive Trading Days prior to but
excluding the Fundamental Change Effective Date.

     The following table sets forth the Additional Share amounts, if any, by which the applicable
Conversion Rate shall be increased for each Stock Price and Fundamental Change Effective Date.

     If the actual Stock Price or Fundamental Change Effective Date is not set forth in the
table above, then:

     (i) if the actual Stock Price on the Fundamental Change Effective Date is between two
Stock Price amounts in the table or the actual Fundamental Change Effective Date is between
two Fundamental Change Effective Dates in the table, the Additional Share amounts will be
determined by a straight-line interpolation between the Additional Share amounts set forth
for the

29

 

higher and lower Stock Prices and the two Fundamental Change Effective Dates on the
table based on a 365-day year;

     (ii) if the actual Stock Price on the Fundamental Change Effective Date exceeds $___
per share of Common Stock, subject to adjustment as set forth herein, no adjustment to the
Conversion Rate shall be made; and

     (iii) if the actual Stock Price on the Fundamental Change Effective Date is less than
$  per share of Common Stock, subject to adjustment as set forth herein, no adjustment to
the Conversion Rate shall be made.

     The Stock Prices set forth in the first column of the table above will be adjusted as of any
date on which the Conversion Rate of the Securities is adjusted pursuant to Section 4.06 hereof.
The adjusted Stock Prices will equal the Stock Prices applicable immediately prior to such
adjustment multiplied by a fraction, the numerator of which is the Conversion Rate immediately
prior to the adjustment giving rise to the Stock Price adjustment and the denominator of which is
the Conversion Rate as so adjusted. The number of Additional Share amounts set forth in the table
above will be adjusted in the same manner as the Conversion Rate as set forth in Section 4.06
hereof.

     Notwithstanding the foregoing, in no event shall the Conversion Rate exceed ___shares per
$1,000 principal amount of Securities, subject to adjustment in the same manner as the Conversion
Rate as set forth in subsections (a) through (e) of Section 4.06 hereof.

     Section 4.02. Conversion Procedure.

     (a) To convert a Security, a Holder must (1) complete and manually sign the conversion notice
on the back of the Security (which shall be substantially in the form set forth in the form of
Security attached as Exhibit A under the heading “Conversion Notice”) and deliver such notice to
the Conversion Agent, (2) surrender the Security to the Conversion Agent, (3) furnish appropriate
endorsements and transfer documents if required by the Conversion Agent, (4) pay an amount equal to
the interest payable on the next Interest Payment Date if and as required by Section 4.02(c) and
(5) pay all transfer or similar taxes, if required pursuant to Section 4.04. The date on which the
Holder of a Security satisfies all of the foregoing requirements is the “Conversion Date” with
respect to such Security. Upon the conversion of a Security, the Company shall deliver the amounts
determined in accordance with Section 4.12 which shall be owing upon such conversion as promptly as
practicable after the applicable Conversion Reference Period but in any event not later than the
third Business Day following the last Trading Day of such Conversion Reference Period. Anything
herein to the contrary notwithstanding, in the case of Global Securities, Securities may be
surrendered in accordance with the Applicable Procedures of the Depositary as in effect from time
to time.

     (b) A Holder shall not be entitled to any rights of a holder of Common Stock until such Holder
has converted its Securities and received upon conversion thereof shares of Common Stock. The
person in whose name any certificate or certificates for shares of Common Stock shall be issuable
upon such conversion, if any, shall become on the date any such certificate or certificates are
delivered to such Holder in accordance with the provisions of this Article 4, the holder of record
of the shares represented thereby. Except as set forth in this Indenture, no payment or adjustment
will be made for dividends or distributions declared or

30

 

made on shares of Common Stock issued upon conversion of a Security prior to the issuance of
such shares of Common Stock.

     (c) Holders of Securities surrendered for conversion (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 will receive the semiannual interest payable on such Securities on
the corresponding Interest Payment Date notwithstanding the conversion, and such interest shall be
payable on the corresponding Interest Payment Date to the Holder of the Security as of the close of
business on the Regular Record Date. Upon surrender of any such Securities for conversion after the
close of business on such Regular Record Date, such Securities shall also be accompanied by payment
by the Holders of such Securities in funds to the Conversion Agent acceptable to the Company of an
amount equal to the interest payable on such corresponding Interest Payment Date; provided that no
such payment need be made: (1) in connection with a conversion following the Regular Record Date
preceding the Final Maturity Date; (2) if the Company has specified a Fundamental Change Purchase
Date that is after a Regular Record Date and on or prior to the corresponding Interest Payment
Date; or (3) to the extent of any overdue interest, if any overdue interest exists at the time of
conversion with respect to such Security. Except as otherwise provided in this Section 4.02(c), no
payment or adjustment will be made for accrued and unpaid interest on a converted Security. Accrued
and unpaid interest shall be deemed paid in full, rather than cancelled, extinguished or forfeited.
The Company shall not be required to convert any Securities which are surrendered for conversion
without payment of interest as required by this Section 4.02(c).

     (d) In the case of any Security which is converted in part only, upon such conversion the
Company shall execute and the Trustee shall authenticate and deliver to the Holder thereof, without
service charge, a new Security or Securities of authorized denominations in an aggregate principal
amount equal to, and in exchange for, the unconverted portion of the principal amount of such
Security.

     Section 4.03. Fractional Shares.

     The Company will not issue fractional shares of Common Stock upon conversion of
Securities. If more than one Security shall be surrendered for conversion at one time by the same
Holder, the number of full shares that shall be issuable upon conversion 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. In lieu of any fractional shares, the Company shall pay an
amount in cash equal to the applicable fraction of a share multiplied by the arithmetic average of
the Volume Weighted Average Price of the Common Stock for the 40 consecutive Trading Days of the
Conversion Reference Period, rounding to the nearest whole cent.

     Section 4.04. Taxes on Conversion.

     The issue of stock certificates, if any, on conversion of Securities shall be made
without charge to the converting Holder for any documentary, stamp or similar issue or transfer tax
in respect of the issue thereof. The Company shall not, however, be required to pay any such tax
which may be payable in respect of any transfer involved in the issue and delivery of stock in any
name other than that of the Holder of any Security converted, and the Company shall not be required
to issue or deliver any such stock certificate unless and until the Person or Persons requesting
the issue thereof shall have paid to the

31

 

Company the amount of such tax or shall have established to the satisfaction of the Company
that such tax has been paid.

     Section 4.05. Company To Provide Common Stock.

     (a) The Company shall, prior to issuance of any Securities hereunder, and from time to time as
may be necessary, reserve, out of its authorized but unissued Common Stock, a sufficient number of
shares of Common Stock to permit the conversion of all outstanding Securities in accordance with
the provisions of this Indenture.

     (b) All shares of Common Stock delivered upon conversion of the Securities shall be newly
issued shares or treasury shares, shall be duly authorized, validly issued, fully paid and
nonassessable and shall be free from preemptive or similar rights and free of any lien or adverse
claim as the result of any action by the Company.

     (c) The Company will endeavor promptly to comply with all federal and state securities laws
regulating the offer and delivery of shares of Common Stock upon conversion of Securities, if any,
and will list or cause to have listed such shares of Common Stock on the New York Stock Exchange,
or each national securities exchange or over the counter market or such other market on which the
Common Stock is then listed or quoted.

     Section 4.06. Adjustment of Conversion Rate.

     The Conversion Rate shall be adjusted from time to time by the Company as follows:

     (a) If the Company issues Common Stock as a dividend or distribution on Common Stock to
all holders of Common Stock, or if the Company effects a share split or share combination, the
Conversion Rate will be adjusted based on the following formula:

	 	 	 
	CR1 =

	 	CR0 x OS1/OS0
	 
	 	 
	where
	 
	 	 
	CR0 =

	 	the Conversion Rate in effect immediately prior to the adjustment relating to such event
	 
	 	 
	CR1 =

	 	the new Conversion Rate in effect taking such event into account
	 
	 	 
	OS0 =

	 	the number of shares of Common Stock outstanding immediately prior to such event
	 
	 	 
	OS1 =

	 	the number of shares of Common Stock outstanding immediately after such event.

Any adjustment made pursuant to this Section 4.06(a) shall become effective on the date that
is immediately after (x) the date fixed for the determination of stockholders entitled to receive
such dividend or other distribution or (y) the date on which such split or combination becomes
effective, as applicable. If any dividend or distribution described in this clause Section 4.06(a)
is declared but not so paid or made,

32

 

the new Conversion Rate shall be readjusted to the Conversion Rate that would then be in effect if
such dividend or distribution had not been declared.

     (b) If the Company issues to all holders of Common Stock any rights, warrants, options or
other securities entitling them for a period of not more than 45 days after the date of issuance
thereof to subscribe for or purchase Common Stock, or if the Company issues to all holders of
Common Stock securities convertible into Common Stock for a period of not more than 45 days after
the date of issuance thereof, in either case at an exercise price per share of Common Stock or a
conversion price per share of Common Stock less than the Closing Price of the Common Stock on the
Business Day immediately preceding the time of announcement of such issuance, the Conversion Rate
will be adjusted based on the following formula:

	 	 	 
	CR1 =

	 	CR0 x (OS0+X)/(OS0+Y)
	 
	 	 
	where
	 
	 	 
	CR0 =

	 	the Conversion Rate in effect immediately prior to the
adjustment relating to such event
	 
	 	 
	CR1 =

	 	the new Conversion Rate taking such event into account
	 
	 	 
	OS0 =

	 	the number of shares of Common Stock outstanding immediately
prior to such event
	 
	 	 
	X =

	 	the total number of shares of Common Stock issuable pursuant
to such rights, warrants, options, other securities or convertible securities
	 
	 	 
	Y =

	 	the number of shares of Common Stock equal to the quotient of
(A) the aggregate price payable to exercise such rights, warrants, options,
other securities or convertible securities and (B) the average of the Closing
Prices of the Common Stock for the 10 consecutive Trading Days prior to the
Business Day immediately preceding the date of announcement for the issuance of
such rights, warrants, options, other securities or convertible securities.

For purposes of this Section 4.06(b), in determining whether any rights, warrants, options,
other securities or convertible securities entitle the holders to subscribe for or purchase, or
exercise a conversion right for, Common Stock at less than the applicable Closing Price of the
Common Stock, and in determining the aggregate exercise or conversion price payable for such Common
Stock, there shall be taken into account any consideration received by the Company for such rights,
warrants, options, other securities or convertible securities and any amount payable on exercise or
conversion thereof, with the value of such consideration, if other than cash, to be determined by
the Board of Directors of the Company. Any adjustment made pursuant to this Section 4.06(b) shall
become effective on the date that is immediately after the date fixed for the determination of
shareholders entitled to receive such rights, warrants, options, other securities or convertible
securities. If any right, warrant, option, other security or convertible security described in this
Section 4.06(b) is not exercised or converted prior to the expiration of the exercisability or
convertibility thereof, the new Conversion Rate shall be readjusted to the Conversion Rate that
would then be in effect if such right, warrant, option, other security or convertible security had
not been so issued.

33

 

     (c) If the Company distributes capital stock, evidences of indebtedness or other assets
or property of the Company to all holders of Common Stock, excluding:

     (1) dividends, distributions, rights, warrants, options, other securities or
convertible securities referred to in Section 4.06(a) or (b) above,

     (2) dividends or distributions paid exclusively in cash, and

     (3) Spin-Offs described below in this Section 4.06(c),

then the Conversion Rate will be adjusted based on the following formula:

	 	 	 
	CR1 =

	 	CR0 x SP0/(SP0-FMV)
	 
	 	 
	where
	 
	 	 
	CR0 =

	 	the Conversion Rate in effect immediately prior to the
adjustment relating to such event
	 
	 	 
	CR1 =

	 	the new Conversion Rate taking such event into account
	 
	 	 
	SP0 =

	 	the Closing Price of the Common Stock on the Trading Day
immediately preceding the ex-dividend date for such distribution
	 
	 	 
	FMV =

	 	the fair market value (as determined in good faith by the Board
of Directors of the Company) of the capital stock, evidences of indebtedness,
assets or property distributed with respect to each outstanding share of Common
Stock on the earlier of the record date or the ex-dividend date for such
distribution.

An adjustment to the Conversion Rate made pursuant to this paragraph shall be made successively
whenever any such distribution is made and shall become effective on the ex-dividend date for such
distribution.

     If the Company distributes to all holders of Common Stock capital stock of any class or
series, or similar equity interest, of or relating to a subsidiary or other business unit of the
Company (a “Spin-Off”), the Conversion Rate in effect immediately before the close of business on
the date fixed for determination of holders of Common Stock entitled to receive such distribution
will be adjusted based on the following formula:

	 	 	 
	CR1 =

	 	CR0 x (FMV0+MP0)/MP0
	 
	 	 
	where
	 
	 	 
	CR0 =

	 	the Conversion Rate in effect immediately prior to the
adjustment relating to such event
	 
	 	 
	CR1 =

	 	the new Conversion Rate taking such event into account

34

 

	 	 	 
	FMV0 =

	 	the average of the Closing Prices of the capital stock or
similar equity interest distributed to holders of Common Stock applicable to
one share of Common Stock over the first 10 consecutive Trading Days after the
effective date of the Spin-Off
	 
	 	 
	MP0 =

	 	the average of the Closing Prices of the Common Stock over
the first 10 consecutive Trading Days after the effective date of the Spin-Off.

An adjustment to the Conversion Rate made pursuant to this paragraph will occur on the 10th Trading
Day from and including the effective date of the Spin-Off.

     If any such dividend or distribution described in this Section 4.06(c) is declared but
not paid or made, the new Conversion Rate shall be readjusted to be the Conversion Rate that would
then be in effect if such dividend or distribution had not been declared.

     (d) If the Company pays or makes any dividend or distribution consisting exclusively of
cash to all holders of Common Stock, the Conversion Rate will be adjusted based on the following
formula:

	 	 	 
	CR1 =

	 	CR0 x (SP0-T)/(SP0-C)
	 
	 	 
	where
	 
	 	 
	CR0 =

	 	the Conversion Rate in effect immediately prior to the
adjustment relating to such event
	 
	 	 
	CR1 =

	 	the new Conversion Rate taking such event into account
	 
	 	 
	SP0 =

	 	the average of the Closing Prices of the Common Stock over
the 10 consecutive Trading-Day period ending on the Trading Day immediately
preceding the ex-dividend date for such distribution
	 
	 	 
	T =

	 	the Dividend Threshold Amount, which shall initially be $0.06
per quarter, adjusted to take into account events that cause adjustments to the
Conversion Rate and as further adjusted to account for any change in the
frequency of payment of regular dividends by the Company; provided that the
Dividend Threshold Amount shall be deemed to be zero if the dividend is not a
regularly scheduled dividend
	 
	 	 
	C =

	 	the amount in cash per share of Common Stock that the Company
distributes to holders of Common Stock.

An adjustment to the Conversion Rate made pursuant to this Section 4.06(d) shall become effective
on the ex-dividend date for such dividend or distribution. If any dividend or distribution
described in this Section 4.06(d) is declared but not so paid or made, the new Conversion Rate
shall be readjusted to the Conversion Rate that would then be in effect if such dividend or
distribution had not been declared.

35

 

     If the Company fails to pay a cash dividend or distribution for a period in which a
regularly scheduled dividend has in prior periods been paid in accordance with past practice, the
Conversion Rate shall be adjusted using the formula in this Section 4(d), with the ex-dividend date
being deemed to be the second to last trading day in the second month of the calendar quarter in
question, and “C” being deemed to be zero.

     Whenever the Conversion Rate is adjusted, the Dividend Threshold Amount shall be adjusted by
multiplying such Dividend Threshold Amount by a fraction, the numerator of which is the Conversion
Rate prior to adjustment and the denominator of which is the Conversion Rate following such
adjustment, except that no such adjustment will be made to the Dividend Threshold Amount on
account of any adjustment to the Conversion Rate pursuant to this Section 4(d).

     (e) If the Company or any of its subsidiaries makes a payment in respect of a tender
offer or exchange offer for Common Stock to the extent that the cash and value of any other
consideration included in the payment per share of Common Stock exceeds the Closing Price of the
Common Stock on the Trading Day next succeeding the last date on which tenders or exchanges may be
made pursuant to such tender or exchange offer (the “Expiration Time”), the Conversion Rate will be
adjusted based on the following formula:

	 	 	 
	CR1 =

	 	CR0 x (AC + (SP1 x OS1))/(SP1 x OS0)
	 
	 	 
	where
	 
	 	 
	CR0 =

	 	the Conversion Rate in effect immediately prior to the
adjustment relating to such event
	 
	 	 
	CR1 =

	 	the new Conversion Rate taking such event into account
	 
	 	 
	AC =

	 	the aggregate value of all cash and any other consideration
(as determined by the Board of Directors of the Company) paid or payable for
Common Stock purchased in such tender or exchange offer
	 
	 	 
	OS0 =

	 	the number of shares of Common Stock outstanding immediately
prior to the date such tender or exchange offer expires
	 
	 	 
	OS1 =

	 	the number of shares of Common Stock outstanding immediately
after such tender or exchange offer expires (after giving effect to the
purchase or exchange of shares pursuant to such tender or exchange offer)
	 
	 	 
	SP1 =

	 	the average of the Closing Prices of Common Stock for the 10
consecutive Trading Days commencing on the Trading Day next succeeding the date
such tender or exchange offer expires.

If the application of the foregoing formula would result in a decrease in the Conversion Rate, no
adjustment to the Conversion Rate will be made.

     Any adjustment to the Conversion Rate made pursuant to this Section 4.06(e) shall become
effective on the date immediately following the determination of the average of the Closing Prices
of Common Stock for purposes of SP1 above. If the Company or one of its subsidiaries is obligated to

36

 

purchase Common Stock pursuant to any such tender or exchange offer but is permanently
prevented by applicable law from effecting any such purchase or all such purchases are rescinded,
the new Conversion Rate shall be readjusted to be the Conversion Rate that would be in effect if
such tender or exchange offer had not been made.

     (f) Notwithstanding the provisions of this Section 4.06, the Conversion Rate shall not
exceed ___shares per $1,000 principal amount of Securities, subject to adjustment in the manner
that the Conversion Rate is subject to adjustment as set forth in subsections (a) through (e) of
this Section 4.06.

     (g) In addition to the adjustments pursuant to clauses (a) through (e) above, the Company may
increase the Conversion Rate in order to avoid or diminish any income tax to holders of Common
Stock resulting from any dividend or distribution of capital shares (or rights to acquire Common
Stock) or from any event treated as such for income tax purposes. The Company may also, from time
to time, to the extent permitted by applicable law, increase the Conversion Rate by any amount for
any period if the Company has determined that such increase would be in the best interests of the
Company. If the Company makes such determination, it will be conclusive and the Company will mail
to Holders of the Securities a notice of the increased Conversion Rate and the period during which
it will be in effect at least fifteen (15) days prior to the date the increased Conversion Rate
takes effect in accordance with applicable law.

     (h) If the Company has in effect a rights plan while any Securities remain outstanding,
Holders will receive, upon a conversion of Securities in respect of which the Company is required
to deliver shares of Common Stock, in addition to such shares of Common Stock, rights under the
Company’s stockholder rights agreement unless, prior to conversion, the rights have expired,
terminated or been redeemed or unless the rights have separated from the Common Stock. If the
rights provided for in the rights plan adopted by the Company have separated from the Common Stock
in accordance with the provisions of the applicable stockholder rights agreement so that Holders
would not be entitled to receive any rights in respect of Common Stock, if any, that the Company is
required to deliver upon conversion of Securities, the Conversion Rate will be adjusted at the time
of separation as if the Company had distributed to all holders of Common Stock capital stock,
evidences of indebtedness or other assets or property pursuant to Section 4.06(c) above, subject to
readjustment upon the subsequent expiration, termination or redemption of the rights.

     (i) For purposes of this Section 4.06, the number of shares of Common Stock at any time
outstanding shall not include shares held in the treasury of the Company but shall include shares
issuable in respect of scrip certificates issued in lieu of fractions of shares of Common Stock.

     Section 4.07. No Adjustment.

     (a) The Company shall not be required to make any adjustment to the Conversion Rate in
accordance with the provisions of Section 4.06 if Holders of the Securities are permitted to
participate, on an as-converted basis, in the transactions described in Section 4.06 (assuming for
this purpose that each $1,000 principal amount of Securities were convertible solely into a number
of shares of Common Stock equal to the Conversion Rate).

37

 

     (b) No adjustment in the Conversion Rate shall be required to be made unless the adjustment
would require an increase or decrease of at least 1% of the Conversion Price. If the adjustment is
not made because the adjustment does not change the Conversion Price by at least 1%, then the
adjustment that is not made will be carried forward and taken into account in any future
adjustment. All required calculations will be made to the nearest cent or 1/1,000th of a share, as
the case may be. Notwithstanding the foregoing, all adjustments not previously made shall have
effect with respect to any conversion of Securities.

     (c) Notwithstanding anything to the contrary contained herein, in addition to the other events
set forth herein on account of which no adjustment to the Conversion Rate shall be made, the
applicable Conversion Rate shall not be adjusted for: (i) the issuance of any Common Stock pursuant
to any present or future plan providing for the reinvestment of dividends or interest payable on
securities of the Company and the investment of additional optional amounts in Common Stock under
any plan; (ii) the issuance of any shares of Common Stock or options or rights to purchase those
shares pursuant to any present or future employee, director or consultant benefit plan, employee
agreement or arrangement or program of the Company; (iii) the issuance of any shares of Common
Stock pursuant to any option, warrant, right, or exercisable, exchangeable or convertible security
outstanding as of the date the Securities were first issued; (iv) a change in the par value of the
Common Stock; (v) accumulated and unpaid dividends or distributions; and (vi) as a result of a
tender offer solely to holders of fewer than 100 shares of Common Stock.

     (d) Notwithstanding anything in this Section 4.06 to the contrary, in no event shall the
Conversion Rate be adjusted so that the Conversion Price would be less than $0.01.

     Section 4.08. Notice of Adjustment.

     Whenever the Conversion Rate is adjusted as herein provided, the Company shall promptly
file with the Trustee and any Conversion Agent other than the Trustee, an Officer’s Certificate
setting forth the Conversion Rate after such adjustment and setting forth a brief statement of the
facts requiring such adjustment. Unless and until a Trust Officer of the Trustee shall have
received such Officer’s Certificate, the Trustee shall not be deemed to have knowledge of any
adjustment of the Conversion Rate and may assume that the last Conversion Rate of which it has
knowledge is still in effect. Promptly after delivery of such certificate, the Company shall
prepare a notice of such adjustment of the Conversion Rate setting forth the adjusted Conversion
Rate and the date on which each adjustment becomes effective and shall mail such notice of such
adjustment of the Conversion Rate to Holders within 20 Business Days of the effective date of such
adjustment. Failure to deliver such notice shall not affect the legality or validity of any such
adjustment.

     Section 4.09. Notice of Certain Transactions.

     In the event that the Company takes any action which would require an adjustment to the
Conversion Rate, the Company takes any action that requires the execution of a supplemental
indenture in accordance with the provisions of Section 4.10 or if there is a dissolution or
liquidation of the Company, the Company shall mail to Holders and file with the Trustee a notice
stating the proposed record or effective date, as the case may be. The Company shall mail such
notice at least 20 days before such proposed effective date. Failure to mail such notice or any
defect therein shall not affect the validity of any transaction referred to in this Section 4.09.

38

 

     Section 4.10. Effect of Reclassification, Consolidation, Merger or Sale on Conversion Privilege.

     (a) If any of following events occur (each, a “Business Combination”), namely:

     (1) any recapitalization, reclassification or change of the Common Stock, other than
(A) a change in par value, or from par value to no par value, or from no par value to par
value, or (B) as a result of subdivision or a combination,

     (2) a consolidation, merger or combination of the Company with another Person,

     (3) a sale, lease or other transfer to another Person of all or substantially all of
the consolidated assets of the Company and its Subsidiaries, or

     (4) any statutory share exchange of the Company with another person,

in each case as a result of which holders of Common Stock are entitled to receive stock, other
securities, other property or assets (including cash or any combination thereof) with respect to or
in exchange for Common Stock, the Company or the successor or purchasing corporation, as the case
may be, shall execute with the Trustee a supplemental indenture (which shall comply with the TIA as
in force at the date of execution of such supplemental indenture if such supplemental indenture is
then required to so comply) providing that from and after the effective date of such Business
Combination, upon conversion of Securities, the settlement of the Conversion Value in accordance
with the provisions of Section 4.12 shall be based on, and each Remaining Share, if any,
deliverable in respect of any such settlement shall consist of, the kind and amount of shares of
stock, other securities or other property or assets (including cash or any combination thereof)
which holders of Common Stock are entitled to receive in respect of each share of Common Stock upon
such Business Combination. For purposes of the foregoing, where a Business Combination involves a
transaction that causes the Common Stock to be converted into the right to receive more than a
single type of consideration based upon any form of stockholder election, such consideration will
be deemed to be the weighted average of the types and amounts of consideration received by the
holders of Common Stock that affirmatively make such an election. If, in the case of any such
Business Combination, the stock or other securities and assets receivable thereupon by a holder of
shares of Common Stock includes shares of stock or other securities and assets of a corporation
other than the successor or purchasing corporation, as the case may be, in such Business
Combination, then such supplemental indenture shall also be executed by such other corporation and
shall contain such additional provisions to protect the interests of the Holders of the Securities
as the Board of Directors shall reasonably consider necessary by reason of the foregoing, including
to the extent practicable the provisions providing for the repurchase rights set forth in Article 3
hereof. The Company shall not become a party to any Business Combination unless its terms are
materially consistent with the provisions of this Section 4.10. The above provisions of this
Section 4.10 shall similarly apply to successive Business Combinations. None of the provisions of
this Section 4.10 shall affect the right of a Holder of Securities to convert its Securities in
accordance with the provisions of this Article 4 prior to the effective date of a Business
Combination.

     If this Section 4.10(a) applies to any event or occurrence, Section 4.06 hereof shall not
apply.

     (b) In the event the Company shall execute a supplemental indenture pursuant to this
Section 4.10, the Company shall promptly file with the Trustee (1) an Officer’s Certificate briefly
stating the reasons therefore and that all conditions precedent have been complied with

39

 

and (2) an Opinion of Counsel to the effect that all conditions precedent thereto and
hereunder have been complied with, and shall promptly mail notice of the execution of such
supplemental indenture to all Holders. Failure to mail such notice or any defect therein shall not
affect the validity of such transaction and such supplemental indenture.

     Section 4.11. Trustee’s Disclaimer.

     (a) The Trustee shall have no duty to determine when an adjustment under this Article 4 should
be made, how it should be made or what such adjustment should be, but may accept as conclusive
evidence of that fact or the correctness of any such adjustment, and shall be protected in relying
upon, an Officer’s Certificate and Opinion of Counsel, including the Officer’s Certificate with
respect thereto which the Company is obligated to file with the Trustee pursuant to Section 4.08.
The Trustee makes no representation as to the validity or value of any securities or assets issued
upon conversion of Securities, and the Trustee shall not be responsible for the Company’s failure
to comply with any provisions of this Article 4, including, without limitation, whether or not a
Supplemental Indenture is required to be executed.

     (b) The Trustee shall not be under any responsibility to determine the correctness of any
provisions contained in any supplemental indenture executed pursuant to Section 4.10, but may
accept as conclusive evidence of the correctness thereof, and shall be fully protected in relying
upon, the Officer’s Certificate and Opinion of Counsel, with respect thereto which the Company is
obligated to file with the Trustee pursuant to Section 4.10.

     Section 4.12. Settlement Upon Conversion.

     (a) Holders surrendering Securities for conversion shall be entitled to receive, for each
$1,000 principal amount of Securities surrendered for conversion: (A) cash in an amount equal to
the lesser of (1) $1,000 and (2) the Conversion Value; and (B) if the Conversion Value is greater
than $1,000, a number of shares of Common Stock (the “Remaining Shares”) equal to the sum of the
Daily Share Amounts for each of the 40 consecutive Trading Days in the Conversion Reference Period,
appropriately adjusted to reflect events occurring during the Conversion Reference Period that
would result in an adjustment to Conversion Rate in accordance with the provisions of Section 4.06,
subject to the Company’s right to deliver cash in lieu of all or a portion of such Remaining Shares
as set forth in Section 4.12(b). The Company will deliver such cash and any shares of Common Stock,
together with any cash payable for fractional shares, to such Holder in accordance with Section
4.02(a).

     (b) The Company may elect to pay cash to the Holders of Securities surrendered for conversion
in lieu of all or a portion of the Remaining Shares otherwise issuable pursuant to Section 4.12(a).
In such event, on any day prior to the first Trading Day of the applicable Conversion Reference
Period, the Company may specify a percentage of the Daily Share Amount that will be settled in cash
(the “Cash Percentage”). If the Company elects to specify a Cash Percentage, the amount of cash
that the Company will deliver for each Trading Day in the applicable Conversion Reference Period
will equal the product of: (1) the Cash Percentage, (2) the Daily Share Amount for such Trading Day
and (3) the Volume Weighted Average Price of the Company’s Common Stock on such Trading Day. The
number of shares that the Company shall deliver in respect of each Trading Day in the applicable
Conversion Reference Period will

40

 

be a percentage of the Daily Share Amount equal to 100% minus the Cash Percentage. If the
Company does not specify a Cash Percentage by the start of the applicable Conversion Reference
Period, the Company shall settle 100% of the Daily Share Amount for each Trading Day in the
applicable Conversion Reference Period with shares of Common Stock; provided, however, that the
Company shall pay cash in lieu of fractional shares otherwise issuable upon conversion of the
Securities in accordance with Section 4.03.

     (c) For the purposes of Sections 4.12(a) and (b), in the event that any of Conversion Value,
Daily Conversion Value, Daily Share Amounts, or Volume Weighted Average Price is not calculable for
all portions of the Conversion Reference Period, the Company’s Board of Directors shall in good
faith determine the values necessary to calculate the Conversion Value, Daily Conversion Value,
Daily Share Amounts, and Volume Weighted Average Price (which calculations shall be evidenced by an
Officer’s Certificate delivered to the Trustee).

ARTICLE 5

COVENANTS

     Section 5.01. Payment of Securities.

     (a) The Company shall promptly make all payments in respect of the Securities on the dates and
in the manner provided in the Securities and this Indenture. A payment of principal or interest
shall be considered paid on the date it is due if the Paying Agent (other than the Company) (or if
the Company is the Paying Agent, the segregated account or separate trust fund maintained by the
Company pursuant to Section 2.04) holds by 10:00 a.m., New York City time, on that date money,
deposited by or on behalf of the Company sufficient to make the payment. Accrued and unpaid
interest on any Security that is payable (whether or not punctually paid or duly provided for) on
any Interest Payment Date shall be paid to the Person in whose name that Security is registered at
the close of business on the Regular Record Date for such interest at the office or agency of the
Company maintained for such purpose. The Company shall, to the fullest extent permitted by law, pay
interest in immediately available funds on overdue principal and interest at the annual rate borne
by the Securities compounded semiannually, which interest shall accrue from the date such overdue
amount was originally due to the day preceding the date payment of such amount, including interest
thereon, has been made or duly provided for. All such interest shall be payable on demand.

     (b) Payment of the principal of and interest, if any, on the Securities shall be made at the
office or agency of the Company maintained for that purpose in the Borough of Manhattan, The City
of New York (which shall initially be the Corporate Trust Office of the Trustee) in such coin or
currency of the United States of America as at the time of payment is legal tender for payment of
public and private debts; provided, however, that at the option of the Company payment of interest
on any Certificated Securities having an aggregate principal amount of $5,000,000 or less may be
made by check mailed to the address of the Person entitled thereto as such address appears in the
Register; provided further that a Holder of a Certificated Security having an aggregate principal
amount of more than $5,000,000 will be paid by wire transfer in immediately available funds at the
election of such Holder if such Holder has provided wire transfer instructions to the Trustee at
least 10 Business Days prior to the payment date. Any wire

41

 

transfer instructions received by the Trustee will remain in effect until revoked by the
Holder. In the case of a permanent Global Security, interest payable on any applicable payment date
will be paid to the Depositary, with respect to that portion of such permanent Global Security held
for its account by Cede & Co. for the purpose of permitting such party to credit the interest
received by it in respect of such permanent Global Security to the accounts of the beneficial
owners thereof.

     Section 5.02. Reports by Company and the Guarantors.

copies of all annual reports, quarterly reports and other documents that it files with the SEC
pursuant to Sections 13 or 15(d) of the Exchange Act. The Company also shall comply with the
provisions of TIA Section 314(a).

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

     Section 5.03. Compliance Certificates.

     The Company shall deliver to the Trustee, within one hundred twenty (120) days after the
end of each fiscal year of the Company (beginning with the fiscal year ending December 31, 2007),
an Officer’s Certificate as to the signer’s knowledge of the Company’s compliance with all
conditions and covenants on its part contained in this Indenture and stating whether or not the
signer knows of any Default or Event of Default. If such signer knows of such a Default or Event of
Default, the Officer’s Certificate shall describe the Default or Event of Default and the efforts
to remedy the same. For the purposes of this Section 5.03, compliance shall be determined without
regard to any grace period or requirement of notice provided pursuant to the terms of this
Indenture. Such certificates need not comply with Section 12.04 of this Indenture.

     Section 5.04. Further Instruments and Acts.

     Upon request of the Trustee, the Company and the Guarantors will execute and deliver such
further instruments and do such further acts as may be reasonably necessary or proper to carry out
more effectively the purposes of this Indenture.

     Section 5.05. Maintenance of Corporate Existence.

     Subject to Article 6, the Company will do or cause to be done all things necessary to
preserve and keep in full force and effect its corporate existence.

     Section 5.06. Stay, Extension And Usury Laws.

     The Company covenants (to the extent that they may lawfully do so) that it shall not at
any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of,
any stay, extension or usury law or other law which would prohibit or forgive the Company from
paying all or any portion of the principal of or accrued but unpaid interest on the Securities as
contemplated herein, wherever enacted, now or at any time hereafter in force, or which may affect
the covenants or the performance of this Indenture, and the Company (to the extent it may lawfully
do so) hereby expressly

42

 

waives all benefit or advantage of any such law and covenants that it will not, by resort to
any such law, 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.

     Section 5.07. Maintenance of Office or Agency.

     The Company shall maintain an office or agency where Securities may be presented or
surrendered for payment. The Company also will maintain an office or agency where Securities may be
surrendered for registration of transfer or exchange and where notices and demands to or upon the
Company in respect of the Securities and this Indenture may be served. The office of the Trustee,
at its Corporate Trust Office, will be such office or agency of the Company, unless the Company
shall designate and maintain some other office or agency for one or more of such purposes. The
Company will give prompt written notice to the Trustee of the location and any change in the
location of any such offices or agencies. If at any time the Company shall fail to maintain any
such required offices or agencies or shall fail to furnish the Trustee with the address thereof,
such presentations, surrenders, notices and demands may be made or served at the office of the
Trustee and the Company hereby appoints the Trustee as its agent to receive all such presentations,
surrenders, notices and demands.

     The Company may from time to time designate one or more other offices or agencies (in or
outside of The City of New York) where the Securities may be presented or surrendered for any or
all such purposes, and may from time to time rescind such designation. The Company will give prompt
written notice to the Trustee of any such designation or rescission and any change in the location
of any such office or agency.

     Section 5.08. Guarantees.

     If any Subsidiary of the Company (including any Subsidiary of the Company formed or
acquired after the Issue Date) shall become a guarantor under the 5.750% Notes or the
6.375% Notes, then such Subsidiary shall (i) execute and deliver to the Trustee a supplemental
indenture pursuant to which such Subsidiary shall unconditionally Guarantee all of the Company’s
obligations under the Securities and this Indenture on the terms set forth in Article Eleven and
(ii) deliver to the Trustee an Opinion of Counsel to the effect that such supplemental indenture
has been duly authorized, executed and delivered by such Subsidiary and constitutes a legal, valid,
binding and enforceable obligation of such Subsidiary, subject to customary exceptions. Such
opinion need not comply with Section 12.04 of this Indenture.

(if other than the Company) shall be a corporation or limited liability company organized
and validly existing under the laws of the United States of America or any

State thereof or the District of Columbia, and shall, in any such case, expressly
assume by a supplemental indenture, the due and punctual payment of the principal of and
interest on all the Securities and the performance and observance of every covenant of this

     (2) after giving effect to the transaction, no Default or Event of Default shall have

transfer complies with this Article 6.01 and, if a supplemental indenture is required in
connection with such transaction, such supplemental indenture complies with this Article,
and that all conditions precedent herein provided for relating to such transaction have been
complied with.

     Section 6.02. Successor Substituted.

     Upon any consolidation of the Company with, or merger of the Company into, any other
Person or any sale, conveyance, assignment, transfer, lease or other disposition of all or
substantially all of the Company’s assets in accordance with Section 6.01, the successor Person
formed by such consolidation or into which the Company is merged or to which such sale, conveyance,
assignment, transfer, lease or other disposition is made shall succeed to, and be substituted for,
and may exercise every right and power of, the Company under this Indenture with the same effect as
if such successor Person had been named as the Company herein, and thereafter, except in the case
of a lease, the predecessor Person shall be relieved of all obligations and covenants under this
Indenture and the Securities.

ARTICLE 7

receipt by the Company of a Notice of Default specifying such failure; or

     (6) one or more defaults shall have occurred under any of the agreements, indentures or
instruments under which the Company or any Restricted Subsidiary then has outstanding
indebtedness in excess of $40 million, individually or in the aggregate, and either:

     (A) such default results from the failure to pay such indebtedness at its
stated final maturity and such default has not been cured or the indebtedness repaid
in full within ten days of the default; or

     (B) such default or defaults have resulted in the acceleration of the maturity
of such indebtedness and such acceleration has not been rescinded or such
indebtedness repaid in full within ten days of the acceleration;

     (7) one or more judgments or orders that exceed $40 million in the aggregate (net
of amounts covered by insurance or bonded) for the payment of money have been entered by a
court or courts of competent jurisdiction against the Company or any Restricted Subsidiary
and such judgment or judgments have not been satisfied, stayed, annulled or rescinded within
60 days after such judgment or judgments become final and nonappealable; or

     (8) any Guarantee by a Significant Subsidiary shall for any reason cease to be, or
shall for any reason be asserted in writing by any Guarantor or the Company not to be, in
full force and effect and enforceable in accordance with its terms, except to the extent
contemplated by this Indenture and any such Guarantee; or

     (9) the Company or any Significant Subsidiary pursuant to or within the meaning of any
Bankruptcy Law:

     (A) commences a voluntary insolvency proceeding;

     (B) consents to the entry of an order for relief against it in an involuntary
insolvency proceeding or consents to its dissolution or winding-up;

     (C) consents to the appointment of a Custodian of it or for any substantial
part of its property; or

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

45

 

or takes any comparable action under any foreign laws relating to insolvency; provided,
however, that the liquidation of any Restricted Subsidiary into another Restricted
Subsidiary, other than as part of a credit reorganization, shall not constitute an Event of
Default under this Section 7.01(a)(9); or

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

     (A) is for relief against the Company or any Significant Subsidiary in an

     (b) Notwithstanding Section 7.01(a) no Event of Default under clause (5) of Section 7.01(a)
shall occur until the Trustee notifies the Company in writing, or the Holders of at least 25% in
aggregate principal amount of the Securities then Outstanding notify the Company and the Trustee in
writing, of the Default (a “Notice of Default”), and the Company does not cure the Default within
the time specified in clause (5) of Section 7.01(a), or obtain a waiver, after receipt of such
notice. A notice given pursuant to this Section 7.01 shall be given by registered or certified
mail, must specify the Default, demand that it be remedied and state that the notice is a Notice of
Default. When any Default under this Section 7.01 is cured, it ceases.

     (c) The Company will deliver to the Trustee, within 30 days after becoming aware of the
occurrence of a Default or Event of Default, written notice thereof.

     Section 7.02. Acceleration.

     If an Event of Default (other than an Event of Default specified in clause (9) or (10) of
Section 7.01(a)) shall occur and be continuing with respect to this Indenture, the Trustee or the
Holders of not less than 25% in aggregate principal amount of the Securities then Outstanding may,
and the Trustee at the request of such Holders shall, declare all unpaid principal of and accrued
interest on all Securities to be due and payable, by a notice in writing to the Company (and to the
Trustee if given by the Holders of the Securities). Upon any such declaration, such principal and
interest shall become due and payable immediately. If an Event of Default specified in clause (9)
or (10) of Section 7.01(a) occurs and is continuing, then all the Securities shall ipso facto
become and be due and payable immediately in an amount equal to the principal amount of the
Securities, together with accrued and unpaid interest, if any, to the date the Securities become
due and payable, without any declaration or other act on the part of the

46

 

Trustee or any Holder. Thereupon, the Trustee may, at its discretion, proceed to protect and
enforce the rights of the Holders of the Securities by appropriate judicial proceedings.

     After a declaration of acceleration with respect to the Securities, but before a judgment or
decree for payment of the money due has been obtained by the Trustee as hereinafter in this Article
provided, the Holders of a majority in aggregate principal amount of the Securities Outstanding, by
written notice to the Company and the Trustee, may rescind and annul such declaration and its
consequences if:

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

     (1) all sums paid or advanced by the Trustee under this Indenture and the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents and counsel,

     (2) all overdue interest on all Outstanding Securities,

     (3) the principal of any Outstanding Securities which have become due otherwise than by
such declaration of acceleration and interest thereon at the rate borne by the Securities,
and

     (4) to the extent that payment of such interest is lawful, interest upon overdue
interest at the rate borne by the Securities;

     (b) the rescission would not conflict with any judgment or decree of a court of competent
jurisdiction; and

     (c) all Events of Default, other than the non-payment of principal of and interest on the
Securities which have become due solely by such declaration of acceleration, have been cured or
waived as provided in Section 7.13. No such rescission shall affect any subsequent Default or
impair any right consequent thereon.

     Notwithstanding the foregoing, to the extent elected by the Company, the sole remedy for
an Event of Default relating to the failure by the Company to comply with the provisions of Section
5.02 of this Indenture shall, for the first 365 days after the occurrence of such an Event of
Default, consist exclusively of the right to receive special interest (“Special Interest”) on the
Securities at an annual rate equal to 0.50% of the principal amount of the Securities. Such Special
Interest shall be paid semi-annually in arrears, with the first semi-annual payment due on the
first Interest Payment Date following the date on which such Special Interest began to accrue on
the Securities. Special Interest shall accrue on all Outstanding Securities from and including the
date on which an Event of Default relating to a failure to comply with the provisions of Section
5.02 shall first occur to but not including the 365th day thereafter (or such earlier date on which
such Event of Default shall have been cured or waived). On such 365th day (or earlier, if the Event
of Default relating to the failure to comply with Section 5.02 is cured or waived prior to such
365th day), such Special Interest shall cease to accrue and, if the Event of Default relating to
the failure to comply with Section 5.02 shall not have been cured or waived prior to such 365th
day, the Securities shall be subject to acceleration as provided in this Section 7.02. The
provisions of this paragraph shall not affect the rights of Holders in the event of the occurrence
of any other Event of Default. In the event the Company shall not elect to pay Special Interest
upon an Event of Default resulting from the failure of the Company to comply with the provisions of
Section 5.02, the Securities shall be subject to acceleration as provided above in this Section
7.02.

47

 

     If the Company shall elect to pay Special Interest in connection with an Event of Default
relating to its failure to comply with the requirements of Section 5.02, (1) the Company shall
notify all Holders and the Trustee and Paying Agent of such election on or before the close of
business on the date on which such Event of Default shall first occur, and (2) all references
herein to interest accrued or payable as of any date shall include any Special Interest accrued or
payable as of such date as provided in this Section 7.02.

     Section 7.03. Collection of Indebtedness and Suits for Enforcement by Trustee.

     The Company covenants that if:

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

     (b) default is made in the payment of the principal of any Security at the Stated 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
interest, with interest upon the overdue principal and, to the extent that payment of such interest
shall be legally enforceable, upon overdue installments of interest, at the rate borne by the
Securities; and, in addition thereto, such further amount as shall be sufficient to cover the costs
and expenses of collection, including the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel.

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

     If an Event of Default occurs and is continuing, the Trustee may in its discretion proceed to
protect and enforce its rights and the rights of the Holders under this Indenture or any Guarantee
by such appropriate private or judicial proceedings as the Trustee shall deem most effectual to
protect and enforce such rights, whether for the specific enforcement of any covenant or agreement
in this Indenture or in any Guarantee or in aid of the exercise of any power granted herein, or to
enforce any other proper remedy, subject however to Section 7.12. No recovery of any such judgment
upon any property of the Company or any Guarantor shall affect or impair any rights, powers or
remedies of the Trustee or the Holders.

     Section 7.04. Trustee May File Proofs of Claim.

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

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

48

 

necessary or advisable in order to have the claims of the Trustee (including any claim for the
reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and
counsel) and of the Holders allowed in such judicial proceeding, and

     (b) to collect and receive any moneys or other property payable or deliverable on any such
claims and to distribute the same;

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or 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 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 8.07.

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

     Section 7.05. Trustee May Enforce Claims Without Possession of Securities.

     All rights of action and claims under this Indenture, the Securities or the Guarantees
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 and 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 7.06. Application of Money Collected.

     Any money collected by the Trustee pursuant to this Article 7 or otherwise on behalf of
the Holders or the Trustee pursuant to this Article 7 or through any proceeding or any arrangement
or restructuring in anticipation or in lieu of any proceeding contemplated by this Article 7 and
any money or other property distributable in respect of the Company’s obligations under this
Indenture after an Event of Default shall be applied, subject to applicable law, in the following
order, at the date or dates fixed by the Trustee and, in case of the distribution of such money on
account of principal or interest, upon presentation of the Securities and the notation thereon of
the payment if only partially paid and upon surrender thereof if fully paid:

     FIRST: To the payment of all amounts due the Trustee (or any predecessor trustee) under
Section 8.07;

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

     THIRD: The balance, if any, to the Person or Persons entitled thereto, including the Company,
provided that all sums due and owing to the Holders and the Trustee have been paid in full as
required by this Indenture.

49

 

     Section 7.07. Limitation on Suits.

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

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

     (b) the Holders of not less than 25% in aggregate principal amount of the Outstanding
Securities shall have made written request to the Trustee to institute proceedings in respect of
such Event of Default in its own name as trustee hereunder;

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

     (d) the Trustee for 15 days after its receipt of such notice, request and offer (and if
requested, provision) of indemnity has failed to institute any such proceeding; and

     (e) no direction inconsistent with such written request has been given to the Trustee during
such 15-day period by the Holders of a majority in principal amount of the Outstanding Securities;

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

     Section 7.08. Unconditional Right of Holders to Receive Payment and to Convert.

     Notwithstanding any other provision of this Indenture, the right of any Holder of a
Security to receive payment of the principal amount, interest, Fundamental Change Purchase Price,
if any, or Special Interest, if any, in respect of the Securities held by such Holder, on or after
the respective due dates expressed in the Securities and this Indenture (whether upon repurchase or
otherwise), and to convert such Security in accordance with Article 4, and to bring suit for the
enforcement of any such payment on or after such respective due dates or for the right to convert
in accordance with Article 4, is absolute and unconditional and shall not be impaired or affected
without the consent of the Holder.

     Section 7.09. 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 the
Company, any other obligor on the Securities, the Trustee and the Holders shall, subject to any
determination in such proceeding, be restored severally and respectively to their former positions
hereunder, and thereafter all rights and remedies of the Trustee and the Holders shall continue as
though no such proceeding had been instituted.

50

 

     Section 7.10. Rights and Remedies Cumulative.

     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 7.11. Delay or Omission Not Waiver.

     No delay or omission of the Trustee or of any Holder of any Security to exercise any
right or remedy accruing upon any Event of Default shall impair any such right or remedy or
constitute a waiver of any such Event of Default or an acquiescence therein. Every right and remedy
given by this Article 7 or by law to the Trustee or to the Holders may be exercised from time to
time, and as often as may be deemed expedient, by the Trustee or by the Holders, as the case may
be.

     Section 7.12. Control by Holders.

     The Holders of not less than a majority in aggregate principal amount of the Outstanding
Securities shall have the right to direct the time, method and place of conducting any proceeding
for exercising any remedy available to the Trustee, or exercising any trust or power conferred on
the Trustee, provided that:

     (a) such direction shall not be in conflict with any rule of law or with this Indenture,
expose the Trustee to personal liability, or be unduly prejudicial to Holders not joining therein;
and

     (b) subject to the provisions of Section 315 of the TIA, the Trustee may take any other action
deemed proper by the Trustee which is not inconsistent with such direction.

     Section 7.13. Waiver of Past Defaults.

     Subject to Section 7.08, the Holders of a majority in aggregate principal amount of the
Securities then Outstanding by notice to the Trustee may waive an existing Default or Event of
Default and its consequences, except an uncured Default or Event of Default in the payment of the
principal of or any accrued but unpaid interest on any Security, an uncured failure by the Company
to convert any Securities into Common Stock and cash, as applicable, or any Default or Event of
Default in respect of any provision of this Indenture or the Securities which, under Section 10.02,
cannot be modified or amended without the consent of the Holder of each Security affected. When a
Default or Event of Default is waived, it is cured and ceases to exist.

     Section 7.14. Undertaking for Costs.

     All parties to this Indenture agree, and each Holder of any Security by his acceptance
thereof shall be deemed to have agreed, that any court may in its discretion require, in any suit
for the enforcement of any right or remedy under this Indenture, or in any suit against the Trustee
for any action taken, suffered or omitted by it as Trustee, the filing by any party litigant in
such suit of an undertaking to pay the costs of such suit, and that such court may in its
discretion assess reasonable costs, including reasonable attorneys’ fees, against any party
litigant in such suit, having due regard to the merits and good

51

 

faith of the claims or defenses made by such party litigant, but the provisions of this
Section shall not apply to any suit instituted by the Trustee, to any suit instituted by any
Holder, or group of Holders, holding in the aggregate more than 10% in principal amount of the
Outstanding Securities, or to any suit instituted by any Holder for the enforcement of the payment
of the principal of or interest on, any Security on or after the respective Stated Maturities
expressed in such Security (or, in the case of purchase pursuant to Article 3 hereof, on the
Fundamental Change Purchase Date).

     Section 7.15. Remedies Subject to Applicable Law.

     All rights, remedies and powers provided by this Article 7 may be exercised only to the
extent that the exercise thereof does not violate any applicable provision of law in the premises,
and all the provisions of this Indenture are intended to be subject to all applicable mandatory
provisions of law which may be controlling in the premises and to be limited to the extent
necessary so that they will not render this Indenture invalid, unenforceable or not entitled to be
recorded, registered or filed under the provisions of any applicable law.

ARTICLE 8

TRUSTEE

     Section 8.01. Duties of Trustee.

     (a) In case an Event of Default has occurred and is continuing, the Trustee shall exercise
such of the rights and powers vested in it by this Indenture, and use the same degree of care and
skill in their exercise, as a prudent person would exercise or use under the circumstances in the
conduct of his own affairs;

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

     (1) the Trustee undertakes to perform those duties and only those duties as are
specifically set forth in this Indenture, and no implied covenants or obligations shall be
read into this Indenture against the Trustee; and

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

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

     (1) this clause (c) does not limit the effect of clauses (b) or (d) of this Section
8.01;

52

 

     (2) the Trustee shall not be liable for any error of judgment made in good faith by a
Trust Officer, unless it is proved that the Trustee was negligent in ascertaining the

take in good faith in accordance with a direction of the Holders of a majority in principal
amount of Outstanding Securities relating to the time, method and place of conducting any
proceeding for any remedy available to the Trustee, or exercising any trust or power
conferred upon the Trustee under this Indenture;

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

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

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

     Within 90 days after the occurrence of any Default, the Trustee shall transmit by mail to
all Holders and any other Persons entitled to receive reports pursuant to Section 313(c) of the
TIA, as their names and addresses appear in the Security Register, notice of such Default hereunder
known to the Trustee, unless such Default shall have been cured or waived; provided, however, that,
except in the case of a Default in the payment of the principal of or interest on any Security or
the failure to deliver amounts owing upon conversion of a Security in accordance with the
provisions of Article 4, the Trustee shall be protected in withholding such notice if and so long
as a trust committee of Trust Officers of the Trustee in good faith determines that the withholding
of such notice is in the interest of the Holders.

     Section 8.03. Certain Rights of Trustee.

     Subject to the provisions of Section 8.01 hereof:

     (a) the Trustee may conclusively rely and shall be fully protected in acting or
refraining from acting upon receipt by it of any resolution, certificate, statement, instrument,

document, but the Trustee, in its discretion, may make such further inquiry or investigation into
such facts or matters as it may deem fit, and, if the Trustee shall determine to make such further

Company, personally or by agent or attorney at the sole cost of the Company and shall incur no

     (i) the permissive rights of the Trustee enumerated herein shall not be construed as duties of
the Trustee;

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

     (k) the rights, privileges, protections, immunities and benefits given to the Trustee,
including, without limitation, its right to be indemnified, are extended to, and shall be

54

 

     (l) the Trustee may request that the Company deliver an Officers’ Certificate setting forth
the names of individuals and/or titles of officers authorized at such time to take specified

riots; interruptions; loss or malfunctions of utilities, computer (hardware or software) or

     Section 8.04. Trustee Not Responsible for Recitals, Dispositions of Securities or
Application of Proceeds Thereof.

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

     Section 8.05. Trustee and Agents May Hold Securities; Collections; etc.

     The Trustee, any Paying Agent, Registrar, Conversion Agent or any other agent of the
Company, in its individual or any other capacity, may become the owner or pledgee of Securities,
with the same rights it would have if it were not the Trustee, Paying Agent, Registrar, Conversion
Agent or such other agent and, subject to TIA Sections 310 and 311, may otherwise deal with the
Company and receive, collect, hold and retain collections from the Company with the same rights it
would have if it were not the Trustee, Paying Agent, Registrar, Conversion Agent or such other
agent.

     Section 8.06. Money Held in Trust.

     All moneys received by the Trustee shall, until used or applied as herein provided, be
held in trust for the purposes for which they were received, but need not be segregated from other
funds except to the extent required by mandatory provisions of law.

     Section 8.07. Compensation and Indemnification of Trustee and Its Prior Claim.

     The Company covenants and agrees to pay to the Trustee from time to time, and the Trustee
shall be entitled to, such compensation as the parties shall agree in writing from time to time 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) and the Company covenants and
agrees to pay or reimburse the Trustee and each predecessor Trustee upon its request for all
reasonable expenses,

55

 

disbursements and advances incurred or made by or on behalf of the Trustee in accordance with
any of the provisions of this Indenture (including the reasonable compensation and the expenses and
disbursements of its counsel and of all agents and other persons not regularly in its employ)
except any such expense, disbursement or advance as may arise from its gross negligence or willful
misconduct. The Company also covenants and agrees to indemnify the Trustee and each predecessor
Trustee for, and to hold it harmless against, any claim, loss, liability, tax, assessment or other
governmental charge (other than taxes applicable to the Trustee’s compensation hereunder) or
expense incurred without gross negligence or willful misconduct on its part, arising out of or in
connection with the acceptance or administration of this Indenture or the trusts hereunder and its
duties hereunder, including enforcement of this Section 8.07 and also including any liability which
the Trustee may incur as a result of failure to withhold, pay or report any tax, assessment or
other governmental charge, and the costs and expenses of defending itself against or investigating
any claim or liability in connection with the exercise or performance of any of its powers or
duties hereunder. The obligations of the Company under this Section 8.07 to compensate and
indemnify the Trustee and each predecessor Trustee and to pay or reimburse the Trustee and each
predecessor Trustee for reasonable expenses, disbursements and advances shall constitute an
additional obligation hereunder and, together with the lien referred to in the next sentence, shall
survive the satisfaction and discharge, and termination for any reason, of this Indenture and the
resignation or removal of the Trustee and each predecessor Trustee. To secure the Company’s
obligations in this Section 8.07, the Trustee shall have a lien prior to the Securities on all
money and property held or collected by the Trustee, other than money or property held in trust for
the payment of principal of or interest on particular Securities.

     “Trustee” for purposes of this Section shall include any predecessor Trustee; provided,
however, that the negligence, willful misconduct or bad faith of any Trustee hereunder shall not
affect the rights of any other Trustee hereunder.

     Without prejudice to its other rights hereunder, when the Trustee incurs expenses or renders
services in connection with an Event of Default specified in Section 7.01(a)(9) or Section
7.01(a)(10), 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.

     Section 8.08. Conflicting Interests.

     The Trustee shall comply with the provisions of Section 310(b) of the TIA. For purposes
of Section 310(b)(1) of the TIA and to the extent permitted thereby, the Trustee, in its capacity
as trustee in respect of the Securities, shall not be deemed to have a conflicting interest arising
from its capacity as trustee in respect of the 5.750% Notes or the 6.375% Notes issued pursuant to
the indenture dated as of July 21, 2005, among the Company, the guarantors named therein, and The
Bank of New York as trustee, or any indenture or indentures pursuant to which other securities or
certificates of interest or participation in other securities of the Company are outstanding if the
requirements for such exclusion set forth in said Section 310(b)(1) are met. Nothing herein shall
preclude the Trustee from making the application referred to in the penultimate paragraph of
Section 310(b) of the TIA.

     Section 8.09. Trustee Eligibility.

     There shall at all times be a Trustee hereunder which shall be eligible to act as trustee
under TIA Section 310(a) and which shall have a combined capital and surplus of at least
$50,000,000, to the extent there is an institution eligible and willing to serve. If the Trustee
does not have a Corporate Trust Office in The City of New York, the Trustee may appoint an agent in
The City of New York reasonably acceptable to the Company to conduct any activities which the
Trustee may be required under this

56

 

Indenture to conduct in The City of New York. If such Trustee publishes reports of condition
at least annually, pursuant to law or to the requirements of federal, state, territorial or
District of Columbia supervising or examining authority, then for the purposes of this Section
8.09, the combined capital and surplus of such corporation shall be deemed to be its combined
capital and surplus as set forth in its most recent report of condition so published. If at any
time the Trustee shall cease to be eligible in accordance with the provisions of this Section 8.09,
the Trustee shall resign immediately in the manner and with the effect hereinafter specified in
this Article 8.

     Section 8.10. Resignation and Removal; Appointment of Successor Trustee.

     (a) No resignation or removal of the Trustee and no appointment of a successor trustee
pursuant to this Article 8 shall become effective until the acceptance of appointment by the
successor trustee under Section 8.11.

     (b) The Trustee, or any trustee or trustees hereafter appointed, may at any time resign by
giving written notice thereof to the Company. Such resignation shall take effect upon the
appointment of a successor Trustee and the acceptance of such appointment by such successor
Trustee. If the instrument of acceptance by a successor Trustee required by Section 811 shall not
have been delivered to the Trustee within 30 days after the giving of such notice of resignation or
of any removal of the Trustee as hereinafter provided, the resigning or removed Trustee may
petition any court of competent jurisdiction for the appointment of a successor Trustee with
respect to the Securities.

     (c) The Trustee may be removed at any time for any cause or for no cause by an Act of the
Holders of not less than a majority in aggregate principal amount of the Outstanding Securities,
delivered to the Trustee and to the Company.

     (d) If at any time:

     (1) the Trustee shall fail to comply with the provisions of TIA Section 310(b) 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,

     (2) the Trustee shall cease to be eligible under Section 8.09 and shall fail to resign
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

     (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 case, (i) the Company may remove the Trustee, or (ii) subject to Section 7.14,
the Holder of any Security 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 and the appointment of a successor trustee. Such court
may thereupon, after such notice, if any, as it may deem proper and prescribe, remove the Trustee
and appoint a successor trustee.

57

 

     (e) If the Trustee shall be removed or become incapable of acting, or if a vacancy shall
occur in the office of Trustee for any cause, the Company shall promptly appoint a successor
trustee and shall comply with the applicable requirements of Section 8.11. If, within 60 days after
such removal or incapability, or the occurrence of such vacancy, the Company has not appointed a
successor Trustee, a successor trustee shall be appointed by the Act of the Holders of a majority
in principal amount of the Outstanding Securities delivered to the Company and the retiring
Trustee. Such successor trustee so appointed shall forthwith upon its acceptance of such
appointment become the successor trustee. If no successor trustee shall have been so appointed by
the Company or the Holders of the Securities and accepted appointment in the manner hereinafter
provided, the Trustee or the Holder of any Security who has been a bona fide Holder for at least
six months may, subject to Section 7.14, on behalf of himself and all others similarly situated,
petition any court of competent jurisdiction for the appointment of a successor trustee.

     (f) The Company shall give notice of each resignation and each removal of the Trustee and each
appointment of a successor trustee by mailing written notice of such event by first-class mail,
postage prepaid, to the Holders of Securities as their names and addresses appear in the register
of the Registrar. Each notice shall include the name of the successor trustee and the address of
its Corporate Trust Office or agent hereunder.

     Section 8.11. Acceptance of Appointment by Successor.

     (a) Every successor trustee appointed hereunder 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 as if originally named as Trustee hereunder; but,
nevertheless, on the written request of the Company or the successor trustee, upon payment of its
charges pursuant to Section 8.07 then unpaid, such retiring Trustee shall pay over to the successor
trustee all moneys at the time held by it hereunder, subject nevertheless to its lien provided for
in Section 8.07, and shall execute and deliver an instrument transferring to such successor trustee
all such rights, powers, trusts and duties. Upon request of any such successor trustee, the
Company shall execute any and all instruments for more fully and certainly vesting in and
confirming to such successor trustee all such rights and powers.

     (b) No successor trustee with respect to the Securities shall accept appointment as provided
in this Section 8.11 unless at the time of such acceptance such successor trustee shall be eligible
to act as trustee under the provisions of TIA Section 310(a) and this Article 8 and shall have a
combined capital and surplus of at least $50,000,000 and have a Corporate Trust Office or an agent
selected in accordance with Section 8.09.

     (c) Upon acceptance of appointment by any successor trustee as provided in this Section 8.11,
the Company shall give notice thereof to the Holders of the Securities, by mailing such notice to
such Holders at their addresses as they shall appear on the Security Register. If the acceptance of
appointment is substantially contemporaneous with the appointment, then the notice called for by
the preceding sentence may be combined with the notice called for by Section 8.10. If the Company
fails to give such notice within 10 days after acceptance of

58

 

appointment by the successor trustee, the successor trustee shall cause such notice to be
given at the expense of the Company.

     Section 8.12. Merger, Conversion, Consolidation or Succession to Business.

     Any Person into which the Trustee may be merged or converted or with which it may be
consolidated, or any Person resulting from any merger, conversion or consolidation to which the
Trustee shall be a party, or any Person succeeding to all or substantially all of the corporate
trust business of the Trustee (including the trust created by this Indenture) shall be the
successor of the Trustee hereunder, provided that such Person shall be eligible under TIA Section
310(a) and this Article 8 and shall have a combined capital and surplus of at least $50,000,000 and
have a Corporate Trust Office or an agent selected in accordance with Section 8.09, without the
execution or filing of any paper or any further act on the part of any of the parties hereto.

     In case at the time such successor to the Trustee shall succeed to the trusts created by this
Indenture any of the Securities shall have been authenticated but not delivered, any such successor
to the Trustee may adopt the certificate of authentication of any predecessor Trustee and deliver
such Securities so authenticated; and, in case at that time any of the Securities shall not have
been authenticated, any successor to the Trustee may authenticate such Securities either in the
name of any predecessor hereunder or in the name of the successor trustee; and in all such cases
such certificate shall have the full force which it is anywhere in the Securities or in this
Indenture provided that the certificate of the Trustee shall have; provided that the right to adopt
the certificate of authentication of any predecessor Trustee or to authenticate Securities in the
name of any predecessor Trustee shall apply only to its successor or successors by merger,
conversion or consolidation.

     Section 8.13. Preferential Collection of Claims Against Company.

     If and when the Trustee shall be or become a creditor of the Company (or other obligor
under the Securities), the Trustee shall be subject to the provisions of the TIA regarding the
collection of claims against the Company (or any such other obligor). A Trustee who has resigned or
been removed shall be subject to TIA Section 311(a) to the extent indicated therein.

     Section 8.14. Reports By Trustee.

     (a) Within 60 days after June 15 of each year commencing with the first June 15 after the
issuance of Securities, the Trustee, if so required under the TIA, shall transmit by mail to all
Holders, in the manner and to the extent provided in TIA Section 313(c), a brief report dated as of
such June 15 in accordance with and with respect to the matters required by TIA Section 313(a). The
Trustee shall also transmit by mail to all Holders, in the manner and to the extent provided in TIA
Section 313(c), a brief report in accordance with and with respect to the matters required by TIA
Section 313(b)(2).

     (b) A copy of each report transmitted to Holders pursuant to this Section 8.14 shall, at the
time of such transmission, be mailed to the Company and filed with each national securities
exchange, if any, upon which the Securities are listed and also with the SEC. The Company will
notify the Trustee promptly if the Securities are listed on any national securities exchange.

59

 

ARTICLE 9

     Section 9.01. Satisfaction and Discharge of Indenture.

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

     (1) all Securities theretofore authenticated and delivered (other than (i)
Securities which have been destroyed, lost or stolen and which have been replaced or paid as
provided in Section 2.08 and (ii) Securities for whose payment money has theretofore been
deposited in trust and thereafter repaid to the Company as provided in Section 2.04) have
been delivered to the Trustee for cancellation; or

     (2) all such Securities not theretofore delivered to the Trustee for cancellation have
become due and payable, whether on the Final Maturity Date or a Fundamental Change Purchase
Date, upon conversion or otherwise,

provided, that

     (i) the Company has deposited with the Trustee, a Paying Agent (other than the
Company or any of its Affiliates) or a Conversion Agent, if applicable, immediately
available funds and/or shares of Common Stock, in trust for the purpose of and in an
amount sufficient to pay and discharge all indebtedness and obligations related to
such Securities not theretofore delivered to the Trustee for cancellation, for
principal and interest to the date of such deposit and/or for the payment of amounts
due upon conversion;

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

     (iii) the Company has delivered to the Trustee an Officer’s Certificate and an
Opinion of Counsel, each stating that all conditions precedent herein relating to
the satisfaction and discharge of this Indenture have been complied with.

     (b) Notwithstanding the satisfaction and discharge of this Indenture, the obligations of the
Company with respect to the Trustee under Section 8.07 and, if money shall have been deposited with
the Trustee pursuant to clause (2) of Section 9.01(a), the provisions of Sections 2.03, 2.04, 2.05,
2.06, 2.07, 2.08, 2.13 and 5.01 and this Article 9 shall survive until the Securities have been
paid in full.

60

 

     Section 9.02. Application of Trust Money.

     Subject to the provisions of the last paragraph of Section 2.04, all United States
dollars deposited with the Trustee pursuant to Section 9.01 shall be held in trust and applied by
it, in accordance with the provisions of the Securities and this Indenture, to the payment, either
directly or through any Paying Agent (including the Company acting as its own Paying Agent) as the
Trustee may determine, to the Persons entitled thereto, of the principal of and interest on, the
Securities for whose payment such United States dollars have been deposited with the Trustee.

     Section 9.03. Reinstatement.

     If the Trustee, any Paying Agent or any Conversion Agent is unable to apply any money in
accordance with Section 9.02 by reason of any legal proceeding or by reason of any order or
judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting
such application, then the Company’s obligations under this Indenture and the Securities shall be
revived and reinstated as though no deposit had occurred pursuant to Section 9.01 until such time
as the Trustee, such Paying Agent or such Conversion Agent is permitted to apply all such money in
accordance with Section 9.02; provided, however, that if the Company has made any payment of the
principal of or interest on any Securities because of the reinstatement of its obligations, the
Company shall be subrogated to the rights of the Holders of such Securities to receive any such
payment from the money held by the Trustee, such Paying Agent or such Conversion Agent.

documents required by Section 12.04, and (subject to Section 8.01 and Section 8.03(a) hereof) shall
be fully protected in relying upon, an Opinion of Counsel and an Officer’s Certificate each stating
that the execution of such supplemental indenture, agreement or instrument, or acceptance of any
such additional trust, is authorized or permitted by this Indenture. The Trustee may, but shall not
be obligated to, enter into any such supplemental indenture, agreement or instrument, or accept any
such additional trusts, which affects the Trustee’s own rights, duties or immunities under this
Indenture or otherwise.

     Section 10.04. Effect of Supplemental Indentures.

     Upon the execution of any supplemental indenture under this Article 10, this Indenture
shall be modified in accordance therewith, and such supplemental indenture shall form a part of

     Securities authenticated and delivered after the execution of any supplemental indenture
pursuant to this Article 10 may, and shall if required by the Trustee, bear a notation in form

for Outstanding Securities.

     Section 10.07. Notice of Supplemental Indentures.

     Promptly after the execution by the Company, any applicable Guarantor and the Trustee of
any supplemental indenture pursuant to the provisions of Section 10.02, the Company shall give

impair or affect the validity of any such supplemental indenture.

ARTICLE 11

NOTE GUARANTEES

     Section 11.01. Guarantees.

     (a) Each Guarantor, hereby jointly and severally, absolutely, unconditionally and irrevocably
guarantees the Securities and obligations of the Company hereunder and thereunder, and guarantees
to each Holder of a Security authenticated and delivered by the Trustee, and to the Trustee on
behalf of such Holder, that (i) the principal of and interest on the Securities will be paid in
full when due, whether at the Final Maturity Date or a Fundamental Change Purchase Date, by
acceleration or otherwise (including, without limitation, the amount that would become due but for
the operation of any automatic stay provision of any Bankruptcy Law), together with interest on the
overdue principal, if any, and interest on any overdue interest, to the extent lawful, and all
other obligations of the Company to the Holders or the Trustee hereunder or thereunder will be paid
in full or performed or observed, all in accordance with the terms hereof and thereof; and (ii) in
case of any extension of time of payment or renewal of any Securities or of any such other
obligations, the same will be paid in full when due or performed or observed in accordance with the
terms of the extension or renewal, whether at the Final Maturity Date or a Fundamental Change
Purchase Date, by acceleration or otherwise, subject, however, in the case of clauses (i) and (ii)
above, to the limitations set forth in Section 11.03 hereof.

     Each Guarantor hereby agrees that its obligations hereunder shall be unconditional,
irrespective of the validity, regularity or enforceability of the Securities or this Indenture, the
absence of any action to enforce the same, any waiver or consent by any Holder of Securities with
respect to any provisions hereof or thereof, any release of any other Guarantor, the recovery of
any judgment against the Company, any action to enforce the same or any other circumstance which
might otherwise constitute a legal or equitable discharge or defense of a Guarantor.

     (b) Each Guarantor hereby waives (to the extent permitted by law) the benefits of
diligence, presentment, demand for payment, filing of claims with a court in the event of

64

 

insolvency or bankruptcy of the Company, any right to require a proceeding first against the
Company or any other Person, protest, notice and all demands whatsoever and covenants that the
Guarantee of such Guarantor shall not be discharged as to Securities except by complete performance
of the obligations contained therein, this Indenture and such Guarantee. Each Guarantor
acknowledges that the Guarantee is a guarantee of payment and not of collection. Each of the
Guarantors hereby agrees that, in the event of a default in payment of principal or interest on
such Security, whether at the Final Maturity Date or a Fundamental Change Purchase Date, by
acceleration or otherwise, legal proceedings may be instituted by the Trustee on behalf of, or by,
the Holder of such Security, subject to the terms and conditions set forth in this Indenture,
directly against each of the Guarantors to enforce such Guarantor’s Guarantee without first
proceeding against the Company or any other Guarantor. Each Guarantor agrees that if, after the
occurrence and during the continuance of an Event of Default, the Trustee or any of the Holders are
prevented by applicable law from exercising their respective rights to accelerate the maturity of
the Securities, to collect interest on the Securities, or to enforce or exercise any other right or
remedy with respect to the Securities, such Guarantor will pay to the Trustee for the account of
the Holders, upon demand therefor, the amount that would otherwise have been due and payable had
such rights and remedies been permitted to be exercised by the Trustee or any of the Holders.

     (c) If any Holder or the Trustee is required by any court or otherwise to return to the
Company or any Guarantor, or any custodian, trustee, liquidator or other similar official acting in
relation to either the Company or any Guarantor , any amount paid by any of them to the Trustee or
such Holder, the Guarantee of each of the Guarantors, to the extent theretofore discharged, shall
be reinstated in full force and effect. Each Guarantor further agrees that, as between each
Guarantor, on the one hand, and the Holders and the Trustee, on the other hand, (x) subject to this
Article 11, the maturity of the obligations guaranteed hereby may be accelerated as provided in
Article 7 hereof for the purposes of the Guarantee of such Guarantor, notwithstanding any stay,
injunction or other prohibition preventing such acceleration in respect of the obligations
guaranteed hereby, and (y) in the event of any acceleration of such obligations as provided in
Article 7 hereof, such obligations (whether or not due and payable) shall forthwith become due and
payable by each Guarantor for the purpose of the Guarantee of such Guarantor.

     (d) Each Guarantee shall remain in full force and effect and continue to be effective should
any petition be filed by or against the Company for liquidation or reorganization, should the
Company become insolvent or make an assignment for the benefit of creditors or should a receiver or
trustee be appointed for all or any significant part of the Company’s assets, and shall, to the
fullest extent permitted by law, continue to be effective or be reinstated, as the case may be, if
at any time payment and performance of the Securities are, pursuant to applicable law, rescinded or
reduced in amount, or must otherwise be restored or returned by any obligee on the Securities,
whether as a “voidable preference,” “fraudulent transfer” or otherwise, all as though such payment
or performance had not been made. In the event that any payment, or any part thereof, is rescinded,
reduced, restored or returned, the Securities shall, to the fullest extent permitted by law, be
reinstated and deemed reduced only by such amount paid and not so rescinded, reduced, restored or
returned.

     (e) To evidence its Guarantee, each Guarantor hereby agrees that a Notation of Guarantee
substantially in the form attached as Exhibit B hereto will be endorsed by an Officer

65

 

of such Guarantor on each Security authenticated and delivered to the Trustee and that this
Indenture or a supplemental indenture to this Indenture substantially in the form of Exhibit C
hereto will be executed on behalf of such Guarantor by one of its Officers. Each Guarantor hereby
agrees that its Guarantee will remain in full force and effect notwithstanding any failure to
endorse on each Security a Notation of Guarantee. The delivery of any Security by the Trustee,
after the authentication thereof hereunder, will be deemed to constitute due delivery of the
Notation of Guarantee set forth in this Indenture by the Guarantors.

     Section 11.02. Severability. 

     In case any provision of any Guarantee 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 11.03. Limitation of Liability. 

     Each Guarantor and by its acceptance hereof each Holder confirms that it is the intention
of all such parties that the Guarantee by each such Guarantor pursuant to its Guarantee not
constitute a fraudulent transfer or conveyance for purposes of the Bankruptcy Law, the Uniform
Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal or state law
or the provisions of its local law relating to fraudulent transfer or conveyance. To effectuate the
foregoing intention, the Holders and each such Guarantor hereby irrevocably agree that the
obligations of such Guarantor under its Guarantee shall be limited to the maximum amount that will
not, after giving effect to all other contingent and fixed liabilities of such Guarantor and after
giving effect to any collections from or payments made by or on behalf of any other Guarantor in
respect of the obligations of such other Guarantor under its Guarantee or pursuant to this Article
11, result in the obligations of such Guarantor under its Guarantee constituting such fraudulent
transfer or conveyance.

     Section 11.04. Contribution.

     In order to provide for just and equitable contribution among the Guarantors, the
Guarantors agree, inter se, that in the event any payment or distribution is made by any Guarantor
under a Guarantee, such Guarantor will be entitled to a contribution from any other Guarantor in a
pro rata amount based on the net assets of each Guarantor determined in accordance with GAAP.

     Section 11.05. Subrogation. 

     Each Guarantor shall be subrogated to all rights of Holders against the Company in
respect of any amounts paid by any Guarantor pursuant to the provisions of Section 11.01; provided,
however, that if an Event of Default has occurred and is continuing, no Guarantor shall be entitled
to enforce or receive any payments arising out of, or based upon, such right of subrogation until
all amounts then due and payable by the Company under this Indenture or the Securities shall have
been paid in full.

     Section 11.06. Reinstatement. 

     Each Guarantor hereby agrees (and each Person who becomes a Guarantor shall agree) that
the Guarantee provided for in Section 11.01 shall continue to be effective or be reinstated, as the
case may be, if at any time, payment, or any part thereof, of any obligations or interest thereon
is rescinded or must otherwise be restored by a Holder to the Company upon the bankruptcy or
insolvency of the Company or any Guarantor.

66

 

     Section 11.07. Release of a Guarantor. 

     Notwithstanding the foregoing, each Guarantee by a Guarantor of the Securities shall
provide by its terms that it shall be automatically and unconditionally released and discharged
upon (i) any sale, exchange or transfer, to any Person not an Affiliate of the Company, of all of
the Company’s Capital Stock in, or all or substantially all the assets of, such Guarantor, which
transaction is in compliance with the terms of this Indenture and pursuant to which transaction
such Guarantor is released from all guarantees, if any, by it of other Indebtedness of the Company
or any of its Subsidiaries, (ii) such Subsidiary ceasing to be a guarantor of the 5.750% Notes and
of the 6.375% Notes (other than by reason of a payment under a guarantee by any Subsidiary) or
(iii) payment in full of all principal and interest on the Securities.

     Section 11.08. Benefits Acknowledged. 

     Each Guarantor acknowledges that it will receive direct and indirect benefits from the
financing arrangements contemplated by this Indenture and that its respective Guarantee and waiver
pursuant to its respective Guarantee is knowingly made in contemplation of such benefits.

ARTICLE 12

MISCELLANEOUS

     Section 12.01. Conflict with Trust Indenture Act.

     If any provision hereof limits, qualifies or conflicts with any provision of the TIA or
another provision which is required or deemed to be included in this Indenture by any of the
provisions of the TIA, the provision or requirement of the TIA shall control. If any provision of
this Indenture modifies or excludes any provision of the TIA that may be so modified or excluded,
the latter provision shall be deemed to apply to this Indenture as so modified or to be excluded,
as the case may be.

     Section 12.02. Notices.

     Any demand, authorization notice, request, consent or communication shall be given in
writing and mailed by first-class mail, postage prepaid, or delivered by recognized overnight
courier addressed as follows or transmitted by facsimile transmission (confirmed by delivery in
person or mail by first-class mail, postage prepaid, or by guaranteed overnight courier) to the
following facsimile numbers:

or at any other address previously furnished in writing to the Holders or the Company or any

other obligor on the Securities by the Trustee.

     Such notices or communications shall be effective only when actually received.

     The Company or the Trustee by notice to the other may designate additional or different
addresses for subsequent notices or communications.

     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, or delivered by recognized overnight courier, to each Holder affected
by such event, at its address as it appears in the register kept by the Primary Registrar, not
later than the latest date, and not earlier than the earliest date, prescribed for the giving of
such notice or by any other manner deemed acceptable to the Trustee. 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. Any notice when mailed to a Holder in the aforesaid manner shall be conclusively deemed to
have been received by such Holder whether or not actually received by such Holder. 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 mail notice of any event as required by any provision of this
Indenture, then any method of giving such notice as shall be reasonably satisfactory to the Trustee
shall be deemed to be a sufficient giving of such notice.

     If the Company mails any notice to a Holder of a Security, it shall mail a copy to the Trustee
and each Registrar, Paying Agent and Conversion Agent.

     Section 12.03. Disclosure of Names and Addresses of Holders.

     Holders may communicate pursuant to TIA Section 312(b) with other Holders with respect to
their rights under this Indenture or the Securities, and the Trustee shall comply with TIA Section
312(b). The Company, the Trustee, the Registrar and any other Person shall have the protection of
TIA 312(c). Further, every Holder of Securities, by receiving and holding the same, agrees with the
Company and the Trustee that neither the Company nor the Trustee or any agent of either of them
shall be held accountable by reason of the disclosure of any information as to the names and
addresses of the Holders in accordance with TIA Section 312, regardless of the source from which
such information was derived, and that the

68

 

Trustee shall not be held accountable by reason of mailing any material pursuant to a request
made under TIA Section 312.

     Section 12.04. Compliance Certificates and Opinions.

     (a) Upon any application or request by the Company to the Trustee to take any action under any
provision of this Indenture (except for the issuance of the Securities on the Issue Date) and as
may be requested by the Trustee, the Company shall furnish to the Trustee an Officer’s Certificate
stating that all conditions precedent, if any, provided for in this Indenture relating to the
proposed action have been complied with, and an Opinion of Counsel stating that in the opinion of
such counsel all such conditions precedent, if any, have been complied with, except that, in the
case of any such application or request as to which the furnishing of such certificates or opinions
is specifically required by any provision of this Indenture relating to such particular application
or request, no additional certificate or opinion need be furnished.

     (b) Every certificate or Opinion of Counsel with respect to compliance with a condition or
covenant provided for in this Indenture shall include:

     (1) a statement that the Person signing such certificate or opinion has read and
understands such covenant or condition and the definitions herein relating thereto;

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

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

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

     Section 12.05. Acts of Holders.

     (a) Any request, demand, authorization, direction, notice, consent, waiver or other action
provided by this Indenture to be given or taken by Holders may be embodied in and evidenced by one
or more instruments of substantially similar tenor signed by such Holders in person or by an agent
duly appointed in writing; and, except as herein otherwise expressly provided, such action shall
become effective when such instrument or instruments are delivered to the Trustee and, where it is
hereby expressly required, to the Company. Such instrument or instruments (and the action embodied
therein and evidenced thereby) are herein sometimes referred to as the “Act” of the Holders signing
such instrument or instruments. Proof of execution of any such instrument or of a writing
appointing any such agent shall be sufficient for any purpose of this Indenture and conclusive in
favor of the Trustee and the Company, if made in the manner provided in this Section 12.05.

     (b) The ownership of Securities shall be proved by the register maintained by the Primary
Registrar.

69

 

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

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

     (e) If the Company shall solicit from the Holders any request, demand, authorization,
direction, notice, consent, waiver or other Act, the Company may, at its option, by or pursuant to
a Board Resolution, fix in advance a record date for the determination of such Holders entitled to
give such request, demand, authorization, direction, notice, consent, waiver or other Act, but the
Company shall have no obligation to do so. Notwithstanding TIA Section 316(c), any such record date
shall be the record date specified in or pursuant to such Board Resolution, which shall be a date
not more than 30 days prior to the first solicitation of Holders generally in connection therewith
and no later than the date such first solicitation is completed.

     (f) If such a record date is fixed, such request, demand, authorization, direction, notice,
consent, waiver or other Act may be given before or after such record date, but only the Holders of
record at the close of business on such record date shall be deemed to be Holders for purposes of
determining whether Holders of the requisite proportion of Securities then Outstanding have
authorized or agreed or consented to such request, demand, authorization, direction, notice,
consent, waiver or other Act, and for this purpose the Securities then Outstanding shall be
computed as of such record date; provided that no such request, demand, authorization, direction,
notice, consent, waiver or other Act by the Holders on such record date shall be deemed effective
unless it shall become effective pursuant to the provisions of this Indenture not later than six
months after such record date.

     (g) For purposes of this Indenture, any action by the Holders which may be taken in writing
may be taken by electronic means or as otherwise reasonably acceptable to the Trustee.

     Section 12.06. Benefits of Indenture.

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

70

 

     Section 12.07. Legal Holidays.

     In any case where any Interest Payment Date, Fundamental Change Purchase Date or Final
Maturity Date of any Security shall not be a Business Day, then (notwithstanding any other
provision of this Indenture or of the Securities) payment of interest or principal need not be made
on such date, but may be made on the next succeeding Business Day with the same force and effect as
if made on such Interest Payment Date, Fundamental Change Purchase Date or Final Maturity Date, and
no interest shall accrue with respect to such payment for the period from and after such Interest
Payment Date, Fundamental Change Purchase Date or Final Maturity Date, as the case may be, to the
next succeeding Business Day.

     Section 12.08. Governing Law; Waiver of Trial by Jury.

     THIS INDENTURE, THE SECURITIES AND THE GUARANTEES SHALL BE GOVERNED BY, AND CONSTRUED IN
ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

     EACH PARTY HERETO, AND EACH HOLDER OF A SECURITY BY ITS ACCEPTANCE THEREOF, HEREBY WAIVES, TO
THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT
OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF, UNDER OR IN CONNECTION WITH THIS
INDENTURE.

     Section 12.09. No Adverse Interpretation of Other Agreements.

     This Indenture may not be used to interpret another indenture, loan or debt agreement of
the Company or a Subsidiary of the Company. Any such indenture, loan or debt agreement may not be
used to interpret this Indenture.

     Section 12.10. No Personal Liability of Directors, Officers, Employees and
Stockholders.

     No director, officer, employee, stockholder, incorporator or agent of the Company or any
Guarantor, as such, will have any liability for any obligations of the Company or such Guarantor
under the Securities, the Guarantees, the Indenture or for any claim based on, in respect of, or by
reason of, such obligations or their creation. Each Holder of the Securities by accepting a
Security waives and releases all such liability.

     Section 12.11. Successors and Assigns.

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

     Section 12.12. Multiple Counterparts.

     The parties may sign multiple counterparts of this Indenture. Each signed counterpart
shall be deemed an original, but all of them together represent the same agreement.

     Section 12.13. Separability Clause.

     In case any provision in this Indenture or in the Securities or Guarantees 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.

71

 

     Section 12.14. Schedules and Exhibits.

     All schedules and exhibits attached hereto are by this reference made a part hereof with
the same effect as if herein set forth in full.

     Section 12.15. Effect of Headings and Table of Contents.

     The Article and Section headings herein and the Table of Contents are for convenience

Mylan Laboratories Inc.

__% Senior Convertible Notes due ____

     1. Interest

     Mylan Laboratories Inc., a Pennsylvania corporation (the “Company”, which term shall include
any successor company under the Indenture hereinafter referred to), promises to pay interest on the
principal amount of this Security at the rate of ___% per annum. The Company shall pay interest

accrued from and including the immediately preceding Interest Payment Date (or if none, from and
including ___, ___) to but excluding the relevant Interest Payment Date. Cash interest will

to be made on a day that is not a Business Day shall be made on the next succeeding Business Day

delay. The Company shall, to the fullest extent permitted by law, pay interest in immediately
available funds on overdue principal and interest at the rate of ___% per annum, compounded
semiannually, which interest shall accrue from the date such overdue amount was originally due to
the day preceding the date payment of such amount, including interest thereon, has been made or
duly provided for.

     Any reference herein to interest accrued or payable as of any date shall include any Special
Interest that may be payable in accordance with the provisions of Section 7.02 of the Indenture.

     2. Method of Payment

     The Company shall pay interest on this Security (except defaulted interest) to the Person who
is the Holder of this Security at the close of business on ___or ___, as the case
may be (each, a “Regular Record Date”) next preceding the related Interest Payment Date. The Holder
must surrender this Security to a Paying Agent to collect payment of principal. The Company will
pay principal and interest in money of the United States that at the time of payment is legal
tender for payment of public and private debts.

     3. Paying Agent, Registrar and Conversion Agent

     Initially, The Bank of New York (the “Trustee”, which term shall include any successor trustee
under the Indenture hereinafter referred to) will act as Paying Agent, Registrar and Conversion
Agent. The Company may change any Paying Agent, Registrar or Conversion Agent without notice to the
Holders. The Company or any of its Affiliates may, subject to certain limitations set forth in the
Indenture, act as Paying Agent.

     4. Indenture

     This Security is one of a duly authorized issue of Securities of the Company designated as its
___% Senior Convertible Notes Due ___(the “Securities”), issued under an Indenture, dated as of
___, ___(together with any supplemental indentures thereto, the “Indenture”), among the
Company, the Guarantors as defined therein and the Trustee. The terms of this Security include
those stated in the Indenture and those required by or made part of the Indenture by reference to
the Trust Indenture Act of 1939, as amended (the “TIA”), as in effect on the date of the Indenture.
This Security is

A-3 

 

subject to all such terms, and the Holder of this Security is referred to the Indenture and
the TIA for a statement of them. The Securities are limited to $___aggregate principal
amount ($___aggregate principal amount if the Underwriters exercise their over-allotment
option in full). The Indenture does not limit other debt of the Company, secured or unsecured.

     Capitalized terms not otherwise defined herein have the meaning ascribed to such terms in the
Indenture.

     5. Purchase of Securities at Option of Holder Upon a Fundamental Change

     Upon a Fundamental Change, at the option of the Holder and subject to the terms and conditions
of the Indenture, the Company shall become obligated to purchase for cash all or any part specified
by the Holder (so long as the principal amount of such part is $1,000 or an integral multiple of
$1,000) of the Securities held by such Holder on the date specified by the Company in accordance
with the provisions of Article 3 of the Indenture. The purchase price of any Securities so
purchased shall equal 100% of the principal amount thereof together with accrued and unpaid
interest, if any, to, but excluding, the Fundamental Change Purchase Date. If the Fundamental
Change Purchase Date falls on a day that is after the Regular Record Date and on or prior to the
corresponding Interest Payment Date, interest, accrued and unpaid hereon to, but not including, the
applicable Fundamental Change Purchase Date, will be paid to the Holder in whose name such Security
is registered at the close of business on the Regular Record Date immediately preceding the
applicable Fundamental Change Purchase Date.

     6. Conversion

     Subject to and upon compliance with the provisions of the Indenture and upon the occurrence of
the events specified in the Indenture, the Holder may surrender for conversion all or any portion
of this Security that is in an integral multiple of $1,000. Upon conversion, the Holder shall be
entitled to receive the consideration specified in the Indenture. No fractional share of Common
Stock shall be issued upon conversion of a Security. Instead, the Company shall pay a cash
adjustment as provided in the Indenture. The initial Conversion Rate of the Securities shall be
___shares of Common Stock per $1,000 principal amount of Securities, subject to adjustment in
accordance with the provisions of Article 4 of the Indenture. If a Holder converts all or any
portion of this Security in connection with the occurrence of certain Fundamental Change
transactions, the Conversion Rate shall be increased in the manner and to the extent described in
Section 4.01(i) of the Indenture.

     Securities surrendered for conversion (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 shall be accompanied by payment by the Holders of such Securities in funds to the
Conversion Agent acceptable to the Company of an amount equal to the interest payable on such
corresponding Interest Payment Date; provided that no such payment need be made: (1) in connection
with a conversion following the Regular Record Date preceding the Final Maturity Date; (2) if the
Company has specified a Fundamental Change Purchase Date that is after a Regular Record Date and on
or prior to the corresponding Interest Payment Date; or (3) to the extent of any overdue interest,
if any overdue interest exists at the time of conversion with respect to such Security.

     A Security in respect of which a Holder has submitted a Fundamental Change Purchase Notice may
be converted only if such Holder validly withdraws such Fundamental Change Purchase Notice in
accordance with the terms of the Indenture.

A-4 

 

     7. Denominations, Transfer, Exchange

     The Securities are in registered form, without coupons, in denominations of $1,000 principal
amount and integral multiples of $1,000 principal amount. A Holder may register the transfer of or
exchange Securities in accordance with the Indenture. The Registrar may require a Holder, among
other things, to furnish appropriate endorsements and transfer documents and to pay any taxes or
other governmental charges that may be imposed in relation thereto by law or permitted by the
Indenture.

     8. Persons Deemed Owners

     The Holder of a Security may be treated as the owner of it for all purposes.

     9. Unclaimed Money

     If money for the payment of principal or interest remains unclaimed for two years, the Trustee
and any Paying Agent will pay the money back to the Company, subject to the provisions of the
Indenture. After that, Holders entitled to money must look to the Company for payment as general
creditors.

     10. Amendment, Supplement and Waiver

     Subject to certain exceptions, the Indenture or the Securities may be amended or supplemented
with the consent of the Holders of at least a majority in aggregate principal amount of the
Securities then outstanding, and an existing Default or Event of Default and its consequence or
compliance with any provision of the Indenture or the Securities may be waived subject to certain
exceptions with the consent of the Holders of a majority in aggregate principal amount of the
Securities then Outstanding. Without the consent of or notice to any Holder, the Company, the
Guarantors and the Trustee may amend or supplement the Indenture or the Securities to, among other
things, (x) cure any ambiguity, omission, mistake, defect or inconsistency or (y) make any other
change that does not adversely affect the interests of the Holders in any material respect.

     11. Successor Entity

     When a successor Person assumes all the obligations of its predecessor under the Securities
and the Indenture in accordance with the terms and conditions of the Indenture, the predecessor
Person (except in certain circumstances specified in the Indenture) shall be released from those
obligations.

     12. Defaults and Remedies

     An Event of Default shall occur upon the occurrence of any of the events specified in Section
7.01(a) of the Indenture. Subject to the provisions of the penultimate paragraph of Section
7.02(c) of the Indenture, if an Event of Default shall occur and be continuing with respect to the
Securities (other than an Event of Default specified in clause (9) or (10) of Section 7.01(a) of
the Indenture), the Trustee or the Holders of not less than 25% in aggregate principal amount of
the Securities then Outstanding may, and the Trustee at the request of such Holders shall, declare
all unpaid principal of and accrued interest on all Securities to be due and payable, by a notice
in writing to the Company (and to the Trustee if given by the Holders of the Securities). Upon any
such declaration, such principal and interest shall become due and payable immediately. If an Event
of Default specified in clauses (9) or (10) of Section 7.01(a) of the Indenture occurs and is
continuing, then all the Securities shall ipso facto become and be due and payable immediately in
an amount equal to the principal amount of the Securities, together with accrued and

A-5 

 

unpaid interest, if any, to the date the Securities become due and payable, without any
declaration or other act on the part of the Trustee or any Holder.

     The Holders of a majority in aggregate principal amount of the Securities Outstanding, by
written notice to the Company and the Trustee, may rescind and annul an acceleration and its
consequences if: (a) the Company has paid or deposited with the Trustee a sum sufficient to pay (1)
all sums paid or advanced by the Trustee under the Indenture and the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel, (2) all overdue
interest on all Outstanding Securities, (3) the principal of any Outstanding Securities which have
become due otherwise than by such declaration of acceleration and interest thereon at the rate
borne by the Securities, and (4) to the extent that payment of such interest is lawful, interest
upon overdue interest at the rate borne by the Securities; (b) the rescission would not conflict
with any judgment or decree of a court of competent jurisdiction; and (c) all Events of Default,
other than the non-payment of principal of and interest on the Securities which have become due
solely by such declaration of acceleration, have been cured or waived. No such rescission shall
affect any subsequent Default or impair any right consequent thereon.

     Holders may not enforce the Indenture or the Securities except as provided in the Indenture.
The Trustee may require indemnity satisfactory to it before it enforces the Indenture or the
Securities. Subject to certain limitations, Holders of a majority in aggregate principal amount of
the Securities then outstanding may direct the Trustee in its exercise of any trust or power. The
Trustee may, in accordance with the provisions of the Indenture, withhold from Holders notice of
any continuing Default (except a Default in payment of principal or interest or to deliver amounts
owing upon conversion) if and so long as it determines that withholding notice is in their
interests. The Company is required to file periodic certificates with the Trustee as to the
Company’s compliance with the Indenture and knowledge or status of any Default.

     13. Trustee Dealings With the Company

     The Bank of New York, the initial Trustee under the Indenture, or any of its Affiliates, in
its individual or any other capacity, may make loans to, accept deposits from and perform services
for the Company or an Affiliate of the Company, and may otherwise deal with the Company or an
Affiliate of the Company, as if it were not the Trustee.

     14. No Recourse Against Others

     No director, officer, employee, stockholder, incorporator or agent of the Company, as such,
will have any liability for any obligations of the Company under the Securities, the Indenture or
for any claim based on, in respect of, or by reason of, such obligations or their creation. Each
Holder of the Securities by accepting a Security waives and releases all such liability.

the certificate of authentication on the other side of this Security.
