cash, securities or otherwise) at which and the terms and conditions upon which Securities
of the series may be redeemed, in whole or in part, at the option of the Company, if the
Company is to have that option, and the manner in which the Company must exercise any such
option, if different from those set forth herein;

with respect to the Securities of the series shall be payable;

conditions upon which such election is to be made;

     (14) if the amount of payments of principal of, premium (if any) and interest on and

Securities of the series, which may amend, supplement, modify or supersede those contained
in this Article II;

     (19) if the Securities of the series are to be convertible into or exchangeable for
capital stock, other debt securities (including Securities), warrants, other equity
securities or any other securities or property of the Company, any Subsidiary Guarantor or
any other Person, at the option of the Company or the Holder or upon the occurrence of any
condition or event, the terms and conditions for such conversion or exchange;

9

 

     (20) if the Securities of the series are to be entitled to the benefit of Section
4.03(b) (and accordingly constitute Rule 144A Securities), that fact; and

     (21) any other terms of the series (which terms shall not be prohibited by the
provisions of this Indenture).

          All Securities of any one series shall be substantially identical except as to denomination
and except as may otherwise be provided in or pursuant to the Board Resolution referred to above
and (subject to Section 2.03) set forth, or determined in the manner provided, in the Officers’
Certificate or Company Order referred to above or in any such indenture supplemental hereto.

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

			
	SECTION 2.02	 	Denominations.

          The Securities of each series shall be issuable in such denominations as shall be specified as
contemplated by Section 2.01. In the absence of any such provisions with respect to the Securities
of any series, the Securities of such series denominated in Dollars shall be issuable in
denominations of $1,000 and any integral multiples thereof.

			
	SECTION 2.03	 	Forms Generally.

          The Securities of each series shall be in fully registered form and in substantially such form
or forms (including temporary or permanent global form) established by or pursuant to a Board
Resolution or in one or more indentures supplemental hereto. The Securities may have notations,
legends or endorsements required by law, securities exchange rule, the Company’s certificate of
incorporation, bylaws or other similar governing documents, agreements to which the Company is
subject, if any, or usage (provided that any such notation, legend or endorsement is in a form
acceptable to the Company). A copy of the Board Resolution establishing the form or forms of
Securities of any series shall be delivered to the Trustee at or prior to the delivery of the
Company Order contemplated by Section 2.04 for the authentication and delivery of such Securities.

          The definitive Securities of each series shall be printed, lithographed or engraved on steel
engraved borders or may be produced in any other manner, all as determined by the Officers
executing such Securities, as evidenced by their execution thereof.

          The Trustee’s certificate of authentication shall be in substantially the following form:

10

 

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

	 	 	 	 	 	 	 
	 	 	, as Trustee	 	 
	 	 	 
	 	 
	 
	 	 	 	 	 	 
	 

	 	By:	 	 	 	 
	 

	 	 	 	 	 	 
	 

	 	 	 	Authorized Signatory”.	 	 

			
	SECTION 2.04	 	Execution, Authentication, Delivery and Dating.

          Two Officers of the Company shall sign the Securities on behalf of the Company and, with
respect to any related Guarantee, an Officer of each Subsidiary Guarantor shall sign the Notation
of Guarantee on behalf of such Subsidiary Guarantor, in each case by manual or facsimile signature.
If an Officer of the Company whose signature is on a Security no longer holds that office at the
time the Security is authenticated, the Security shall be valid nevertheless.

          A Security shall not be entitled to any benefit under this Indenture or the related
Guarantees, if any, or be valid or obligatory for any purpose until authenticated by the manual
signature of an authorized signatory of the Trustee, which signature shall be conclusive evidence
that the Security has been authenticated under this Indenture. Notwithstanding the foregoing, if
any Security has been authenticated and delivered hereunder but never issued and sold by the
Company, and the Company delivers such Security to the Trustee for cancellation as provided in
Section 2.13, together with a written statement (which need not comply with Section 11.05 and need
not be accompanied by an Opinion of Counsel) stating that such Security has never been issued and
sold by the Company, for all purposes of this Indenture such Security shall be deemed never to have
been authenticated and delivered hereunder and shall never be entitled to the benefits of this
Indenture or the related Guarantees, if any.

          At any time and from time to time after the execution and delivery of this Indenture, the
Company may deliver Securities of any series executed by the Company to the Trustee for
authentication, and the Trustee shall authenticate and deliver such Securities for original issue
upon a Company Order for the authentication and delivery of such Securities or pursuant to such
procedures acceptable to the Trustee as may be specified from time to time by Company Order. Such
order shall specify the amount of the Securities to be authenticated, the date on which the
original issue of Securities is to be authenticated, the name or names of the initial Holder or
Holders and any other terms of the Securities of such series not otherwise determined. If provided
for in such procedures, such Company Order may authorize (1) authentication and delivery of
Securities of such series for original issue from time to time, with certain terms (including,
without limitation, the Maturity dates or dates, original issue date or dates and interest rate or
rates) that differ from Security to Security and (2) may authorize authentication and delivery
pursuant to oral or electronic instructions from the Company or its duly authorized agent, which
instructions shall be promptly confirmed in writing.

          If the form or terms of the Securities of the series have been established in or pursuant to
one or more Board Resolutions as permitted by Section 2.01, in authenticating such Securities, and
accepting the additional responsibilities under this Indenture in relation to such Securities, the
Trustee shall be entitled to receive (in addition to the Company Order referred to

11

 

above and the other documents required by Section 11.04), and (subject to Section 7.01) shall
be fully protected in relying upon:

     (a) an Officers’ Certificate setting forth the Board Resolution and, if applicable, an
appropriate record of any action taken pursuant thereto, as contemplated by the last
paragraph of Section 2.01; and

     (b) an Opinion of Counsel to the effect that:

     (i) the form of such Securities has been established in conformity with the
provisions of this Indenture;

     (ii) the terms of such Securities have been established in conformity with the
provisions of this Indenture; and

     (iii) that such Securities and the related Guarantees, if any, when
authenticated and delivered by the Trustee and issued by the Company in the manner
and subject to any conditions specified in such Opinion of Counsel, will constitute
valid and binding obligations of the Company and the Subsidiary Guarantors,
respectively, enforceable against the Company and the Subsidiary Guarantors,
respectively, in accordance with their respective terms, except as the
enforceability thereof may be limited by applicable bankruptcy, insolvency,
reorganization, moratorium, fraudulent conveyance or other similar laws in effect
from time to time affecting the rights of creditors generally, and the application
of general principles of equity (regardless of whether such enforceability is
considered in a proceeding in equity or at law).

          If all the Securities of any series are not to be issued at one time, it shall not be
necessary to deliver an Officers’ Certificate and Opinion of Counsel at the time of issuance of
each such Security, but such Officers’ Certificate and Opinion of Counsel shall be delivered at or
before the time of issuance of the first Security of the series to be issued.

          The Trustee shall not be required to authenticate such Securities if the issuance of such
Securities pursuant to this Indenture would affect the Trustee’s own rights, duties or immunities
under the Securities and this Indenture or otherwise in a manner not reasonably acceptable to the
Trustee.

          The Trustee may appoint an authenticating agent acceptable to the Company to authenticate
Securities. Unless limited by the terms of such appointment, an authenticating agent may
authenticate Securities whenever the Trustee may do so. Each reference in this Indenture to
authentication by the Trustee includes authentication by such agent. An authenticating agent has
the same rights as an Agent to deal with the Company, any Subsidiary Guarantor or any other
Affiliate of the Company.

          Each Security shall be dated the date of its authentication.

12

 

			
	SECTION 2.05	 	Registrar and Paying Agent.

          The Company shall maintain an office or agency for each series of Securities where Securities
of such series may be presented for registration of transfer or exchange (“Registrar”) and an
office or agency where Securities of such series may be presented for payment (“Paying Agent”).
The Registrar shall keep a register of the Securities of such series and of their transfer and
exchange. The Company may appoint one or more co-registrars and one or more additional paying
agents. The term “Registrar” includes any co-registrar and the term “Paying Agent” includes any
additional paying agent.

          The Company shall enter into an appropriate agency agreement with any Registrar or 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 any Agent not a party to this Indenture. The Company may change any Paying Agent or Registrar
without notice to any Holder. If the Company fails to appoint or maintain another entity as
Registrar or Paying Agent, the Trustee shall act as such. The Company or any Subsidiary may act as
Paying Agent or Registrar.

          The Company initially appoints the Trustee as Registrar and Paying Agent.

			
	SECTION 2.06	 	Paying Agent to Hold Money in Trust.

          The Company shall require each Paying Agent other than the Trustee to agree in writing that
the Paying Agent will hold in trust for the benefit of Holders or the Trustee all money held by the
Paying Agent for the payment of principal of, premium, if any, or interest on or any Additional
Amounts with respect to Securities and will notify the Trustee of any default by the Company in
making any such payment. While any such default continues, the Trustee may require a Paying Agent
to pay all money held by it to the Trustee and to account for any funds disbursed. The Company at
any time may require a Paying Agent to pay all money held by it to the Trustee and to account for
any funds disbursed. Upon payment over to the Trustee and upon accounting for any funds disbursed,
the Paying Agent (if other than the Company, a Subsidiary Guarantor or another Subsidiary) shall
have no further liability for the money. If the Company or a Subsidiary acts as Paying Agent, it
shall segregate and hold in a separate trust fund for the benefit of the Holders all money held by
it as Paying Agent. Each Paying Agent shall otherwise comply with TIA § 317(b).

			
	SECTION 2.07	 	Holder Lists.

          The Trustee shall preserve in as current a form as is reasonably practicable the most recent
list available to it of the names and addresses of Holders and shall otherwise comply with TIA §
312(a). If the Trustee is not the Registrar with respect to a series of Securities, the Company
shall furnish to the Trustee at least five Business Days before each Interest Payment Date with
respect to such series of Securities, and at such other times as the Trustee may request in
writing, a list in such form and as of such date as the Trustee may reasonably require of the names
and addresses of Holders of such series, and the Company shall otherwise comply with TIA § 312(a).

13

 

			
	SECTION 2.08	 	Transfer and Exchange.

          Except as set forth in Section 2.17 or as may be provided pursuant to Section 2.01:

          When Securities of any series are presented to the Registrar with the request to register the
transfer of such Securities or to exchange such Securities for an equal principal amount of
Securities of the same series of like tenor and of other authorized denominations, the Registrar
shall register the transfer or make the exchange as requested if its requirements and the
requirements of this Indenture for such transactions are met; provided, however, that the
Securities presented or surrendered for registration of transfer or exchange shall be duly endorsed
or accompanied by a written instruction of transfer in form reasonably satisfactory to the
Registrar duly executed by the Holder thereof or by his attorney, duly authorized in writing, on
which instruction the Registrar can rely.

          To permit registrations of transfers and exchanges, the Company shall execute and the Trustee
shall authenticate Securities at the Registrar’s written request and submission of the Securities
or Global Securities. No service charge shall be made to a Holder for any registration of transfer
or exchange (except as otherwise expressly permitted herein), but the Company may require payment
of a sum sufficient to cover any transfer tax or similar governmental charge payable in connection
therewith (other than such transfer tax or similar governmental charge payable upon exchanges
pursuant to Section 2.12, 3.07 or 9.05). The Trustee shall authenticate Securities in accordance
with the provisions of Section 2.04. Notwithstanding any other provisions of this Indenture to the
contrary, the Company shall not be required to register the transfer or exchange of (a) any
Security selected for redemption in whole or in part pursuant to Article III, except the unredeemed
portion of any Security being redeemed in part, or (b) any Security during the period beginning 15
Business Days prior to the mailing of notice of any offer to repurchase Securities of the series
required pursuant to the terms thereof or of redemption of Securities of a series to be redeemed
and ending at the close of business on the day of mailing.

			
	SECTION 2.09	 	Replacement Securities.

          If any mutilated Security is surrendered to the Trustee, or if the Holder of a Security claims
that the Security has been destroyed, lost or stolen and the Company and the Trustee receive
evidence to their satisfaction of the destruction, loss or theft of such Security, the Company
shall issue and the Trustee shall authenticate a replacement Security of the same series if the
Trustee’s requirements are met. If any such mutilated, destroyed, lost or stolen Security has
become or is about to become due and payable, the Company in its discretion may, instead of issuing
a new Security, pay such Security. If required by the Trustee, any Subsidiary Guarantor or the
Company, such Holder must furnish an indemnity bond that is sufficient in the judgment of the
Trustee and the Company to protect the Company, each Subsidiary Guarantor, the Trustee, any Agent
or any authenticating agent from any loss that any of them may suffer if a Security is replaced.
The Company and the Trustee may charge a Holder for their expenses in replacing a Security.

          Every replacement Security is an additional obligation of the Company.

14

 

			
	SECTION 2.10	 	Outstanding Securities.

          The Securities outstanding at any time are all the Securities authenticated by the Trustee
except for those canceled by it, those delivered to it for cancellation, those reductions in the
interest in a Global Security effected by the Trustee hereunder and those described in this Section
2.10 as not outstanding.

          If a Security is replaced pursuant to Section 2.09, it ceases to be outstanding unless the
Trustee receives proof satisfactory to it that the replaced Security is held by a bona fide
purchaser.

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

          A Security does not cease to be outstanding because the Company, a Subsidiary Guarantor or
another Affiliate of the Company or an Affiliate of a Subsidiary Guarantor holds the Security.

			
	SECTION 2.11	 	Original Issue Discount, Foreign-Currency Denominated and Treasury Securities.

          In determining whether the Holders of the required principal amount of Securities have
concurred in any direction, amendment, supplement, waiver or consent, (a) the principal amount of
an Original Issue Discount Security shall be the principal amount thereof that would be due and
payable as of the date of such determination upon acceleration of the Maturity thereof pursuant to
Section 6.02, (b) the principal amount of a Security denominated in a foreign currency shall be the
Dollar equivalent, as determined by the Company by reference to the noon buying rate in The City of
New York for cable transfers for such currency, as such rate is certified for customs purposes by
the Federal Reserve Bank of New York (the “Exchange Rate”) on the date of original issuance of such
Security, of the principal amount (or, in the case of an Original Issue Discount Security, the
Dollar equivalent, as determined by the Company by reference to the Exchange Rate on the date of
original issuance of such Security, of the amount determined as provided in (a) above), of such
Security and (c) Securities owned by the Company, a Subsidiary Guarantor or any other obligor upon
the Securities or any Affiliate of the Company or a Subsidiary Guarantor or of such other obligor
shall be disregarded, except that, for the purpose of determining whether the Trustee shall be
protected in relying upon any such direction, amendment, supplement, waiver or consent, only
Securities that a Responsible Officer of the Trustee actually knows are so owned shall be so
disregarded.

			
	SECTION 2.12	 	Temporary Securities.

          Until definitive Securities of any series are ready for delivery, the Company may prepare and
the Trustee shall authenticate temporary Securities. Temporary Securities shall be substantially
in the form of definitive Securities, but may have variations that the Company considers
appropriate for temporary Securities. Without unreasonable delay, the Company shall prepare and
the Trustee shall authenticate definitive Securities in exchange for temporary Securities. Until
so exchanged, the temporary Securities shall in all respects be entitled to the same benefits under
this Indenture as definitive Securities.

15

 

			
	SECTION 2.13	 	Cancellation.

          The Company or any Subsidiary Guarantor at any time may deliver Securities to the Trustee for
cancellation. The Registrar and the Paying Agent shall forward to the Trustee any Securities
surrendered to them for registration of transfer, exchange, payment or redemption or for credit
against any sinking fund payment. The Trustee shall cancel all Securities surrendered for
registration of transfer, exchange, payment, redemption, replacement or cancellation or for credit
against any sinking fund. Unless the Company shall direct in writing that canceled Securities be
returned to it, after written notice to the Company all canceled Securities held by the Trustee
shall be disposed of in accordance with the usual disposal procedures of the Trustee, and the
Trustee shall maintain a record of their disposal. The Company may not issue new Securities to
replace Securities that have been paid or that have been delivered to the Trustee for cancellation.

			
	SECTION 2.14	 	Payments; Defaulted Interest.

          Unless otherwise provided as contemplated by Section 2.01, interest (except defaulted
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 Persons who are registered Holders of that Security at
the close of business on the record date next preceding such Interest Payment Date, even if such
Securities are canceled after such record date and on or before such Interest Payment Date. The
Holder must surrender a Security to a Paying Agent to collect principal payments. Unless otherwise
provided with respect to the Securities of any series, the Company will pay the principal of,
premium (if any) and interest on and any Additional Amounts with respect to the Securities in
Dollars. Such amounts shall be payable at the offices of the Trustee or any Paying Agent, provided
that at the option of the Company, the Company may pay such amounts (1) by wire transfer with
respect to Global Securities or (2) by check payable in such money mailed to a Holder’s registered
address with respect to any Securities.

          If the Company defaults in a payment of interest on the Securities of any series, the Company
shall pay the defaulted interest in any lawful manner plus, to the extent lawful, interest on the
defaulted interest, in each case at the rate provided in the Securities of such series and in
Section 4.01. The Company may pay the defaulted interest to the Persons who are Holders on a
subsequent special record date. At least 15 days before any special record date selected by the
Company, the Company (or the Trustee, in the name of and at the expense of the Company upon 20
days’ prior written notice from the Company setting forth such special record date and the interest
amount to be paid) shall mail to Holders a notice that states the special record date, the related
payment date and the amount of such interest to be paid.

			
	SECTION 2.15	 	Persons Deemed Owners.

          The Company, the Subsidiary Guarantors, the Trustee, any Agent and any authenticating agent
may treat the Person in whose name any Security is registered as the owner of such Security for the
purpose of receiving payments of principal of, premium (if any) or interest on or any Additional
Amounts with respect to such Security and for all other purposes. None of the Company, any
Subsidiary Guarantor, the Trustee, any Agent or any authenticating agent shall be affected by any
notice to the contrary.

16

 

			
	SECTION 2.16	 	Computation of Interest.

          Except as otherwise specified as contemplated by Section 2.01 for Securities of any series,
interest on the Securities of each series shall be computed on the
basis of a 360-day year comprising
twelve 30-day months.

			
	SECTION 2.17	 	Global Securities; Book-Entry Provisions.

          If Securities of a series are issuable in global form as a Global Security, as contemplated by
Section 2.01, then, notwithstanding clause (10) of Section 2.01 and the provisions of Section 2.02,
any such Global Security shall represent such of the outstanding Securities of such series as shall
be specified therein and may provide that it shall represent the aggregate amount of outstanding
Securities from time to time endorsed thereon and that the aggregate amount of outstanding
Securities represented thereby may from time to time be reduced or increased, as appropriate, to
reflect exchanges, transfers or redemptions. Any endorsement of a Global Security to reflect the
amount, or any increase or decrease in the amount, of outstanding Securities represented thereby
shall be made by the Trustee (i) in such manner and upon instructions given by such Person or
Persons as shall be specified in such Security or in a Company Order to be delivered to the Trustee
pursuant to Section 2.04 or (ii) otherwise in accordance with written instructions or such other
written form of instructions as is customary for the Depositary for such Security, from such
Depositary or its nominee on behalf of any Person having a beneficial interest in such Global
Security. Subject to the provisions of Section 2.04 and, if applicable, Section 2.12, the Trustee
shall deliver and redeliver any Security in permanent global form in the manner and upon
instructions given by the Person or Persons specified in such Security or in the applicable Company
Order. With respect to the Securities of any series that are represented by a Global Security, the
Company and the Subsidiary Guarantors authorize the execution and delivery by the Trustee of a
letter of representations or other similar agreement or instrument in the form customarily provided
for by the Depositary appointed with respect to such Global Security. Any Global Security may be
deposited with the Depositary or its nominee, or may remain in the custody of the Trustee or the
Security Custodian therefor pursuant to a FAST Balance Certificate Agreement or similar agreement
between the Trustee and the Depositary. If a Company Order has been, or simultaneously is,
delivered, any instructions by the Company with respect to endorsement or delivery or redelivery of
a Security in global form shall be in writing but need not comply with Section 11.05 and need not
be accompanied by an Opinion of Counsel.

          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 the
Trustee or the Security Custodian as its custodian, or under such Global Security, and the
Depositary may be treated by the Company, any Subsidiary Guarantor, the Trustee or the Security
Custodian and any agent of the Company, any Subsidiary Guarantor, the Trustee or the Security
Custodian as the absolute owner of such Global Security for all purposes whatsoever.
Notwithstanding the foregoing, (i) the registered holder of a Global Security of a series may grant
proxies and otherwise authorize any Person, including Agent Members and Persons that may hold
interests through Agent Members, to take any action that a Holder of Securities of such series is
entitled to take under this Indenture or the Securities of such series and (ii) nothing herein
shall prevent the Company, any Subsidiary Guarantor, the Trustee or the

17

 

Security Custodian, or any agent of the Company, any Subsidiary Guarantor, the Trustee or the
Security Custodian, from giving effect to any written certification, proxy or other authorization
furnished by the Depositary or shall impair, as between the Depositary and its Agent Members, the
operation of customary practices governing the exercise of the rights of a beneficial owner of any
Security.

          Notwithstanding Section 2.08, and except as otherwise provided pursuant to Section 2.01:
Transfers of a Global Security shall be limited to transfers of such Global Security in whole, but
not in part, to the Depositary, its successors or their respective nominees. Interests of
beneficial owners in a Global Security may be transferred in accordance with the rules and
procedures of the Depositary. Securities shall be transferred to all beneficial owners in exchange
for their beneficial interests in a Global Security if, and only if, either (1) the Depositary
notifies the Company that it is unwilling or unable to continue as Depositary for the Global
Security and a successor Depositary is not appointed by the Company within 90 days of such notice,
(2) an Event of Default has occurred with respect to such series and is continuing and the
Registrar has received a request from the Depositary to issue Securities in lieu of all or a
portion of the Global Security (in which case the Company shall deliver Securities within 30 days
of such request) or (3) the Company determines not to have the Securities represented by a Global
Security.

          In connection with any transfer of a portion of the beneficial interests in a Global Security
to beneficial owners pursuant to this Section 2.17, the Registrar shall reflect on its books and
records the date and a decrease in the principal amount of the Global Security in an amount equal
to the principal amount of the beneficial interests in the Global Security to be transferred, and
the Company shall execute, and the Trustee upon receipt of a Company Order for the authentication
and delivery of Securities shall authenticate and deliver, one or more Securities of the same
series of like tenor and amount.

          In connection with the transfer of all the beneficial interests in a Global Security to
beneficial owners pursuant to this Section 2.17, the Global Security shall be deemed to be
surrendered to the Trustee for cancellation, and the Company shall execute, and the Trustee shall
authenticate and deliver, to each beneficial owner identified by the Depositary in exchange for its
beneficial interests in the Global Security, an equal aggregate principal amount of Securities of
authorized denominations.

          None of the Company, any Subsidiary Guarantor or the Trustee will have any responsibility or
liability for any aspect of the records relating to, or payments made on account of, Securities by
the Depositary, or for maintaining, supervising or reviewing any records of the Depositary relating
to such Securities. None of the Company, any Subsidiary Guarantor or the Trustee shall be liable
for any delay by the related Global Security Holder or the Depositary in identifying the beneficial
owners, and each such Person may conclusively rely on, and shall be protected in relying on,
instructions from such Global Security Holder or the Depositary for all purposes (including with
respect to the registration and delivery, and the respective principal amounts, of the Securities
to be issued).

          The provisions of the last sentence of the third paragraph of Section 2.04 shall apply to any
Global Security if such Global Security was never issued and sold by the Company and the Company or
a Subsidiary Guarantor delivers to the Trustee the Global Security together

18

 

with written instructions (which need not comply with Section 11.05 and need not be
accompanied by an Opinion of Counsel) with regard to the cancellation or reduction in the principal
amount of Securities represented thereby, together with the written statement contemplated by the
last sentence of the third paragraph of Section 2.04.

          Notwithstanding the provisions of Sections 2.03 and 2.14, unless otherwise specified as
contemplated by Section 2.01, payment of principal of, premium (if any) and interest on and any
Additional Amounts with respect to any Global Security shall be made to the Person or Persons
specified therein.

ARTICLE III

REDEMPTION

			
	SECTION 3.01	 	Applicability of Article.

          Securities of any series that are redeemable before their Stated Maturity shall be redeemable
in accordance with their terms and (except as otherwise specified as contemplated by Section 2.01
for Securities of any series) in accordance with this Article III.

			
	SECTION 3.02	 	Notice to the Trustee.

          If the Company elects to redeem Securities of any series pursuant to this Indenture, it shall
notify the Trustee of the Redemption Date and the principal amount of Securities of such series to
be redeemed. The Company shall so notify the Trustee at least 45 days before the Redemption Date
(unless a shorter notice shall be satisfactory to the Trustee) by delivering to the Trustee an
Officers’ Certificate stating that such redemption will comply with the provisions of this
Indenture and of the Securities of such series. Any such notice may be canceled at any time prior
to the mailing of such notice of such redemption to any Holder and shall thereupon be void and of
no effect. A redemption or notice thereof may be subject to one or more conditions.

			
	SECTION 3.03	 	Selection of Securities To Be Redeemed.

          If less than all the Securities of any series are to be redeemed (unless all of the Securities
of such series of a specified tenor are to be redeemed), the particular Securities to be redeemed
shall be selected not more than 60 days prior to the Redemption Date by the Trustee from the
outstanding Securities of such series (and tenor) not previously called for redemption, either at
random, by lot or by such other method as the Trustee shall deem fair and appropriate and that may
provide for the selection for redemption of portions (equal to the minimum authorized denomination
for Securities of that series or any integral multiple thereof) of the principal amount of
Securities of such series of a denomination larger than the minimum authorized denomination for
Securities of that series or of the principal amount of Global Securities of such series.

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

19

 

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

			
	SECTION 3.04	 	Notice of Redemption.

          Notice of redemption shall be given by first-class mail, postage prepaid, mailed not less than
30 nor more than 60 days prior to the Redemption Date, to each Holder of Securities to be redeemed,
at the address of such Holder appearing in the register of Securities maintained by the Registrar.

          All notices of redemption shall identify the Securities to be redeemed and shall state:

     (1) the Redemption Date;

     (2) the Redemption Price;

     (3) that, unless the Company and the Subsidiary Guarantors default in making the
redemption payment, interest on Securities called for redemption ceases to accrue on and
after the Redemption Date, and the only remaining right of the Holders of such Securities is
to receive payment of the Redemption Price upon surrender to the Paying Agent of the
Securities redeemed;

     (4) if any Security is to be redeemed in part, the portion of the principal amount
thereof to be redeemed and that on and after the Redemption Date, upon surrender for
cancellation of such Security to the Paying Agent, a new Security or Securities in the
aggregate principal amount equal to the unredeemed portion thereof will be issued without
charge to the Holder;

     (5) that Securities called for redemption must be surrendered to the Paying Agent to
collect the Redemption Price and the name and address of the Paying Agent;

     (6) that the redemption is for a sinking or analogous fund, if such is the case;

     (7) the CUSIP number, if any, relating to such Securities; and

     (8) if the redemption or notice thereof is subject to one or more conditions, a
statement to such effect and the condition or conditions precedent.

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

20

 

			
	SECTION 3.05	 	Effect of Notice of Redemption.

          Once notice of redemption is mailed, unless the redemption or notice thereof is subject to one
or more conditions as specified in the notice, Securities called for redemption become due and
payable on the Redemption Date and at the Redemption Price. Upon surrender to the Paying Agent,
such Securities called for redemption shall be paid at the Redemption Price, but interest
installments whose maturity is on or prior to such Redemption Date will be payable on the relevant
Interest Payment Dates to the Holders of record at the close of business on the relevant record
dates specified pursuant to Section 2.01.

			
	SECTION 3.06	 	Deposit of Redemption Price.

          On or prior to 11:00 a.m., New York City time, on any Redemption Date, the Company or a
Subsidiary Guarantor shall deposit with the Trustee or the Paying Agent (or, if the Company or a
Subsidiary Guarantor is acting as the Paying Agent, segregate and hold in trust as provided in
Section 2.06) an amount of money in same day funds sufficient to pay the Redemption Price of, and
(except if the Redemption Date shall be an Interest Payment Date) accrued interest on and any
Additional Amounts with respect to, the Securities or portions thereof which are to be redeemed on
that date, other than Securities or portions thereof called for redemption on that date which have
been delivered by the Company or a Subsidiary Guarantor to the Trustee for cancellation.

          If the Company or a Subsidiary Guarantor complies with the preceding paragraph, then, unless
the Company or the Subsidiary Guarantors default in the payment of such Redemption Price, interest
on the Securities to be redeemed will cease to accrue on and after the applicable Redemption Date,
whether or not such Securities are presented for payment, and the Holders of such Securities shall
have no further rights with respect to such Securities except for the right to receive the
Redemption Price upon surrender of such Securities. If any Security called for redemption shall
not be so paid upon surrender thereof for redemption, the principal, premium, if any, any
Additional Amounts, and, to the extent lawful, accrued interest thereon shall, until paid, bear
interest from the Redemption Date at the rate specified pursuant to Section 2.01 or provided in the
Securities or, in the case of Original Issue Discount Securities, such Securities’ yield to
maturity.

			
	SECTION 3.07	 	Securities Redeemed or Purchased in Part.

          Upon surrender to the Paying Agent of a Security to be redeemed in part, the Company shall
execute and the Trustee shall authenticate and deliver to the Holder of such Security without
service charge a new Security or Securities, of the same series and of 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 that is not redeemed.

			
	SECTION 3.08	 	Purchase of Securities.

          Unless otherwise specified as contemplated by Section 2.01, the Company, any Subsidiary
Guarantor or any Affiliate of the Company or any Subsidiary Guarantor may, subject to applicable
law, at any time purchase or otherwise acquire Securities in the open market or by

21

 

private agreement. Any such acquisition shall not operate as or be deemed for any purpose to
be a redemption of the indebtedness represented by such Securities. Any Securities purchased or
acquired by the Company or a Subsidiary Guarantor may be delivered to the Trustee and, upon such
delivery, the indebtedness represented thereby shall be deemed to be satisfied. Section 2.13 shall
apply to all Securities so delivered.

			
	SECTION 3.09	 	Mandatory and Optional Sinking Funds.

          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.” Unless otherwise provided by the terms of Securities of any
series, the cash amount of any sinking fund payment may be subject to reduction as provided in
Section 3.10. Each sinking fund payment shall be applied to the redemption of Securities of any
series as provided for by the terms of Securities of such series and by this Article III.

			
	SECTION 3.10	 	Satisfaction of Sinking Fund Payments with Securities.

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

			
	SECTION 3.11	 	Redemption of Securities for Sinking Fund.

          Not less than 45 days prior (unless a shorter period shall be satisfactory to the Trustee) to
each sinking fund payment date for any series of Securities, the Company will deliver to the
Trustee an Officers’ Certificate of the Company specifying the amount of the next ensuing sinking
fund payment for that series pursuant to the terms of that series, the portion thereof, if any,
which is to be satisfied by payment of cash and the portion thereof, if any, which is to be
satisfied by delivery of or by crediting Securities of that series pursuant to Section 3.10 and
will also deliver or cause to be delivered to the Trustee any Securities to be so delivered.
Failure of the Company to timely deliver or cause to be delivered such Officers’ Certificate and
Securities specified in this paragraph, if any, shall not constitute a default but shall constitute
the election of the Company (i) that the mandatory sinking fund payment for such series due on the
next succeeding sinking fund payment date shall be paid entirely in cash without the option to
deliver or credit Securities of such series in respect thereof and (ii) that the Company will make
no optional sinking fund payment with respect to such series as provided in this Section.

22

 

          If the sinking fund payment or payments (mandatory or optional or both) to be made in cash on
the next succeeding sinking fund payment date plus any unused balance of any preceding sinking fund
payments made in cash shall exceed $100,000 (or the Dollar equivalent thereof based on the
applicable Exchange Rate on the date of original issue of the applicable Securities) or a lesser
sum if the Company shall so request with respect to the Securities of any particular series, such
cash shall be applied on the next succeeding sinking fund payment date to the redemption of
Securities of such series at the sinking fund redemption price together with accrued interest to
the date fixed for redemption. If such amount shall be $100,000 (or the Dollar equivalent thereof
as aforesaid) or less and the Company makes no such request then it shall be carried over until a
sum in excess of $100,000 (or the Dollar equivalent thereof as aforesaid) is available. Not less
than 30 days before each such sinking fund payment date, the Trustee shall select the Securities to
be redeemed upon such sinking fund payment date in the manner specified in Section 3.03 and cause
notice of the redemption thereof to be given in the name of and at the expense of the Company in
the manner provided in Section 3.04. Such notice having been duly given, the redemption of such
Securities shall be made upon the terms and in the manner stated in Sections 3.05, 3.06 and 3.07.

ARTICLE IV

COVENANTS

			
	SECTION 4.01	 	Payment of Securities.

          The Company shall pay the principal of, premium (if any) and interest on and any Additional
Amounts with respect to the Securities of each series on the dates and in the manner provided in
the Securities of such series and in this Indenture. Principal, premium, interest and any
Additional Amounts shall be considered paid on the date due if the Paying Agent (other than the
Company, a Subsidiary Guarantor or other Subsidiary) holds as of 11:00 a.m. New York time on that
date money deposited by the Company or a Subsidiary Guarantor designated for and sufficient to pay
all principal, premium, interest and any Additional Amounts then due.

          The Company shall pay interest (including post-petition interest in any proceeding under any
Bankruptcy Law) on overdue principal and premium (if any), at a rate equal to the then applicable
interest rate on the Securities to the extent lawful; and it shall pay interest (including
post-petition interest in any proceeding under any Bankruptcy Law) on overdue installments of
interest and any Additional Amount (without regard to any applicable grace period) at the same rate
to the extent lawful.

			
	SECTION 4.02	 	Maintenance of Office or Agency.

          The Company will maintain in each Place of Payment for any series of Securities an office or
agency (which may be an office of the Trustee, the Registrar or the Paying Agent) where Securities
of that series may be presented for registration of transfer or exchange, where Securities of that
series may be presented for payment and where notices and demands to or upon the Company or a
Subsidiary Guarantor in respect of the Securities of that series and this Indenture may be served.
Unless otherwise designated by the Company by written notice to the Trustee and the Subsidiary
Guarantors, such office or agency shall be the office or agency of the

23

 

Trustee in The City of New York, which on the date hereof is located at U.S. Bank Trust, N.A.,
100 Wall Street, 16th Floor, New York, NY 10005. The Company will give prompt written notice to
the Trustee and the Subsidiary Guarantors 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 and the Subsidiary Guarantors with the address thereof,
such presentations, surrenders, notices and demands may be made or served at the Corporate Trust
Office of the Trustee.

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

			
	SECTION 4.03	 	SEC Reports; Financial Statements.

          (a) If the Company is subject to the requirements of Section 13 or 15(d) of the Exchange Act,
the Company shall file with the Trustee, within 15 days after it files the same with the SEC,
copies of the annual reports and the information, documents and other reports (or copies of such
portions of any of the foregoing as the SEC may by rules and regulations prescribe) that the
Company is required to file with the SEC pursuant to Section 13 or 15(d) of the Exchange Act. If
this Indenture is qualified under the TIA, but not otherwise, the Company shall also comply with
the provisions of TIA § 314(a). Delivery of such reports, information and documents to the Trustee
shall be for informational purposes only, and the Trustee’s receipt thereof shall not constitute
constructive notice of any information contained therein or determinable from information contained
therein, including the Company’s and the Subsidiary Guarantors’ compliance with any of their
covenants hereunder (as to which the Trustee is entitled to rely exclusively on Officers’
Certificates or certificates delivered pursuant to Section 4.04).

          So
long as the Company is required to file periodic reports under
Section 13(a) or Section 15(d) of the Securities Exchange Act of
1934, as amended, the Company’s obligation to deliver the
information referred to above shall be deemed satisfied upon the
filing of such information in the EDGAR system and the giving of
notice to the Trustee as to the public availability of such
information from such source.

          (b) If the Company is not subject to the requirements of Section 13 or 15(d) of the Exchange
Act, the Company shall furnish to all Holders of Rule 144A Securities and prospective purchasers of
Rule 144A Securities designated by the Holders of Rule 144A Securities, promptly upon their
request, the information required to be delivered pursuant to Rule 144A(d)(4) promulgated under the
Securities Act of 1933, as amended.

			
	SECTION 4.04	 	Compliance Certificate.

          (a) Each of the Company and the Subsidiary Guarantors shall deliver to the Trustee, within 120
days after the end of each fiscal year of the Company, a statement signed by an Officer of the
Company and each Subsidiary Guarantor, respectively, which need not constitute an Officers’
Certificate, complying with TIA § 314(a)(4) and stating that in the course of performance by the
signing Officer of his duties as such Officer of the Company or such Subsidiary Guarantor, as the
case may be, he would normally obtain knowledge of the keeping, observing, performing and
fulfilling by the Company or such Subsidiary Guarantor, as the case

24

 

may be, of its obligations
under this Indenture, and further stating that to the best of his
knowledge the Company or such Subsidiary Guarantor, as the case may be, has kept, observed,
performed and fulfilled each and every covenant contained in this Indenture and is not in default
in the performance or observance of any of the terms, provisions and conditions hereof (or, if a
Default or Event of Default shall have occurred, describing all such Defaults or Events of Default
of which such Officer may have knowledge and what action the Company or such Subsidiary Guarantor,
as the case may be, is taking or proposes to take with respect thereto).

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

			
	SECTION 4.05	 	Corporate Existence.

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

			
	SECTION 4.06	 	Waiver of Stay, Extension or Usury Laws.

          Each of the Company and the Subsidiary Guarantors covenants (to the extent that it may
lawfully do so) that it will not at any time insist upon, or plead, or in any manner whatsoever
claim or take the benefit or advantage of, any stay or extension law or any usury law or other law
that would prohibit or forgive it from paying all or any portion of the principal of or 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 (to the extent that it may
lawfully do so) each of the Company and the Subsidiary Guarantors hereby expressly waives all
benefit or advantage of any such law, and covenants that it will not hinder, delay or impede the
execution of any power herein granted to the Trustee, but will suffer and permit the execution of
every such power as though no such law had been enacted.

			
	SECTION 4.07	 	Additional Amounts.

          If the Securities of a series expressly provide for the payment of Additional Amounts, the
Company will pay to the Holder of any Security of such series Additional Amounts as expressly
provided therein. Whenever in this Indenture there is mentioned, in any context, the payment of
the principal of or any premium or interest on, or in respect of, any Security of any series or the
net proceeds received from the sale or exchange of any Security of any series, such mention shall
be deemed to include mention of the payment of Additional Amounts provided for in this Section 4.07
to the extent that, in such context, Additional Amounts are, were or would be payable in respect
thereof pursuant to the provisions of this Section 4.07 and express mention of the payment of
Additional Amounts (if applicable) in any provisions hereof shall not be construed as excluding
Additional Amounts in those provisions hereof where such express mention is not made. The Trustee
shall not be deemed to have knowledge of any Additional Amounts owing unless it receives written
notice thereof either

25

 

from the Company or the holders of not less than 25% in principal amount of the then
outstanding Securities.

ARTICLE V

SUCCESSORS

			
	SECTION 5.01	 	Limitations on Mergers and Consolidations.

          Neither the Company nor any Subsidiary Guarantor shall, in any transaction or series of
transactions, consolidate with or merge into any Person, or sell, lease, convey, transfer or
otherwise dispose of all or substantially all of its assets to any Person (other than a
consolidation or merger of one or more Subsidiary Guarantors into the Company or a merger of
Subsidiary Guarantors, or a sale, lease, conveyance, transfer or other disposition of all or
substantially all of the assets of a Subsidiary Guarantor to the Company or of a Subsidiary
Guarantor to another Subsidiary Guarantor), unless:

     (1) either (a) the Company or such Subsidiary Guarantor, as the case may be, shall be
the continuing Person or (b) the Person (if other than the Company or such Subsidiary
Guarantor) formed by such consolidation or into which the Company or such Subsidiary
Guarantor is merged, or to which such sale, lease, conveyance, transfer or other disposition
shall be made (collectively, the “Successor”), expressly assumes by supplemental indenture
the due and punctual payment of the principal of, premium (if any) and interest on and any
Additional Amounts with respect to all the Securities and the performance of the Company’s
covenants and obligations under this Indenture and the Securities, or, in the case of such
Subsidiary Guarantor, the performance of the Guarantee and such Subsidiary Guarantor’s
covenants and obligations under this Indenture and the Securities;

     (2) immediately after giving effect to such transaction or series of transactions, no
Default or Event of Default shall have occurred and be continuing or would result therefrom;
and

     (3) the Company delivers to the Trustee an Officers’ Certificate and an Opinion of
Counsel, each stating that the transaction and such supplemental indenture comply with this
Indenture.

			
	SECTION 5.02	 	Successor Person Substituted.

          Upon any consolidation or merger of the Company or a Subsidiary Guarantor, as the case may be,
or any sale, lease, conveyance, transfer or other disposition of all or substantially all of the
assets of the Company or such Subsidiary Guarantor in accordance with Section 5.01, the Successor
formed by such consolidation or into or with which the Company or the Subsidiary Guarantor is
merged or to which such sale, lease, conveyance, transfer or other disposition is made shall
succeed to, and be substituted for, and may exercise every right and power of the Company or such
Subsidiary Guarantor, as the case may be, under this Indenture and the Securities with the same
effect as if such Successor had been named as the Company or such Subsidiary Guarantor, as the case
may be, herein and the predecessor Company or

26

 

Subsidiary Guarantor, in the case of a sale, conveyance, transfer or other disposition, shall
be released from all obligations under this Indenture, the Securities and, in the case of a
Subsidiary Guarantor, the Guarantee.

ARTICLE VI

DEFAULTS AND REMEDIES

			
	SECTION 6.01	 	Events of Default.

          Unless either inapplicable to a particular series or specifically deleted or modified in or
pursuant to the supplemental indenture or Board Resolution establishing such series of Securities
or in the form of Security for such series, an “Event of Default,” wherever used herein with
respect to Securities of any series, occurs if:

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

          (2) the Company defaults in the payment of (A) the principal of any Security of that
series at its Maturity or (B) premium (if any) on any Security of that series when the same
becomes due and payable;

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

          (4) the Company, or if any series of Securities outstanding is entitled to the benefits
of a Guarantee, any Subsidiary Guarantor, fails to comply with any of its other covenants or
agreements in, or provisions of, the Securities of such series or this Indenture (other than
an agreement, covenant or provision that has expressly been included in this Indenture
solely for the benefit of one or more series of Securities other than that series);

          (5) the Company, or if that series of Securities is entitled to the benefits of a
Guarantee by any Subsidiary Guarantor, any Subsidiary Guarantor, or any Significant
Subsidiary, pursuant to or within the meaning of any Bankruptcy Law:

     (A) commences a voluntary case,

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

     (C) consents to the appointment of a Bankruptcy Custodian of it or for all or
substantially all of its property, or

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

27

 

          (6) a court of competent jurisdiction enters an order or decree under any Bankruptcy
Law that remains unstayed and in effect for 90 days and that:

     (A) is for relief against the Company, any Subsidiary Guarantor with respect to
such series, or a Significant Subsidiary, as debtor in an involuntary case,

     (B) appoints a Bankruptcy Custodian of the Company, any Subsidiary Guarantor,
or a Significant Subsidiary, or a Bankruptcy Custodian for all or substantially all
of the property of the Company, any Subsidiary Guarantor with respect to such
series, or a Significant Subsidiary, or

     (C) orders the liquidation of the Company, any Subsidiary Guarantor with
respect to such series, or a Significant Subsidiary; or

          (7) any Guarantee of any Subsidiary Guarantor with respect to such series
ceases to be in full force and effect with respect to Securities of that series
(except as otherwise provided in this Indenture) or is declared null and void in a
judicial proceeding, or any such Subsidiary Guarantor denies or disaffirms its
obligations under this Indenture or such Guarantee; or

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

          The term “Bankruptcy Custodian” means any receiver, trustee, assignee, liquidator or similar
official under any Bankruptcy Law.

          The Trustee shall not be deemed to know or have notice of any Default or Event of Default
unless a Responsible Officer of the Trustee has actual knowledge thereof or unless written notice
of any event which is in fact such a Default or Event of Default is received by the Trustee at the
Corporate Trust Office of the Trustee, and such notice references the Securities and this
Indenture.

          When a Default is cured, it ceases.

          Notwithstanding the foregoing provisions of this Section 6.01, if the principal of, premium
(if any) or interest on or Additional Amounts with respect to any Security is payable in a currency
or currencies (including a composite currency) other than Dollars and such currency or currencies
are not available to the Company or a Subsidiary Guarantor for making payment thereof due to the
imposition of exchange controls or other circumstances beyond the control of the Company or such
Subsidiary Guarantor (a “Conversion Event”), the Company will be entitled to satisfy its
obligations to Holders of the Securities by making such payment in Dollars in an amount equal to
the Dollar equivalent of the amount payable in such other currency, as determined by the Company or
the Subsidiary Guarantor, as the case may be, by reference to the Exchange Rate 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 6.01, any payment made
under such circumstances in Dollars where the required

28

 

payment is in a currency other than Dollars will not constitute an Event of Default under this
Indenture.

          Promptly after the occurrence of a Conversion Event, the Company or a Subsidiary Guarantor
shall give written notice thereof to the Trustee; and the Trustee, promptly after receipt of such
notice, shall give notice thereof in the manner provided in Section 11.02 to the Holders. Promptly
after the making of any payment in Dollars as a result of a Conversion Event, the Company or a
Subsidiary Guarantor, as the case may be, shall give notice in the manner provided in Section 11.02
to the Holders, setting forth the applicable Exchange Rate and describing the calculation of such
payments.

          A Default under clause (4) of this Section 6.01 is not an Event of Default until the Trustee
notifies the Company and the Subsidiary Guarantors, or the Holders of at least 25% in principal
amount of the then outstanding Securities of the series affected by such Default notify the
Company, the Subsidiary Guarantors and the Trustee, of the Default, and the Company or the
applicable Subsidiary Guarantor, as the case may be, fails to cure the Default within 60 days after
receipt of the notice. The notice must specify the Default, demand that it be remedied and state
that the notice is a “Notice of Default.”

			
	SECTION 6.02	 	Acceleration.

          If an Event of Default with respect to any Securities of any series at the time outstanding
(other than an Event of Default specified in clause (5) or (6) of Section 6.01) occurs and is
continuing, the Trustee by notice to the Company and the Subsidiary Guarantors, or the Holders of
at least 25% in principal amount of the then outstanding Securities of the series affected by such
Event of Default by notice to the Company, the Subsidiary Guarantors and the Trustee, may declare
the principal of (or, if any such Securities are Original Issue Discount Securities, such portion
of the principal amount as may be specified in the terms of that series) and all accrued and unpaid
interest on all then outstanding Securities of such series to be due and payable. Upon any such
declaration, the amounts due and payable on the Securities shall be due and payable immediately.
If an Event of Default specified in clause (5) or (6) of Section 6.01 hereof occurs, such amounts
shall ipso facto become and be immediately due and payable without any declaration, notice or other
act on the part of the Trustee or any Holder. The Holders of a majority in principal amount of the
then outstanding Securities of the series affected by such Event of Default by written notice to
the Trustee may rescind an acceleration and its consequences (other than nonpayment of principal of
or premium or interest on or any Additional Amounts with respect to the Securities) if the
rescission would not conflict with any judgment or decree and if all existing Events of Default
with respect to Securities of that series have been cured or waived, except nonpayment of
principal, premium, interest or any Additional Amounts that has become due solely because of the
acceleration.

			
	SECTION 6.03	 	Other Remedies.

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

29

 

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

			
	SECTION 6.04	 	Waiver of Defaults.

          Subject to Sections 6.07 and 9.02, the Holders of a majority in principal amount of the then
outstanding Securities of any series by notice to the Trustee may waive an existing or past Default
or Event of Default with respect to such series and its consequences (including waivers obtained in
connection with a tender offer or exchange offer for Securities of such series or a solicitation of
consents in respect of Securities of such series, provided that in each case such offer or
solicitation is made to all Holders of then outstanding Securities of such series), except (1) a
continuing Default or Event of Default in the payment of the principal of, or premium, if any, or
interest on or any Additional Amounts with respect to any Security or (2) a continued Default in
respect of a provision that under Section 9.02 cannot be amended or supplemented without the
consent of each Holder affected. Upon any such waiver, such Default shall cease to exist, and any
Event of Default arising therefrom shall be deemed to have been cured for every purpose of this
Indenture; but no such waiver shall extend to any subsequent or other Default or impair any right
consequent thereon.

			
	SECTION 6.05	 	Control by Majority.

          With respect to Securities of any series, the Holders of a majority in principal amount of the
then outstanding Securities of such series may direct in writing the time, method and place of
conducting any proceeding for any remedy available to the Trustee or exercising any trust or power
conferred on it relating to or arising under an Event of Default. However, the Trustee may refuse
to follow any direction that conflicts with applicable law or this Indenture, that the Trustee
determines may be unduly prejudicial to the rights of other Holders, or that may involve the
Trustee in personal liability; provided, however, that the Trustee may take any other action deemed
proper by the Trustee that is not inconsistent with such direction. Prior to taking any action
hereunder, the Trustee shall be entitled to indemnification satisfactory to it in its sole
discretion from Holders directing the Trustee against all losses and expenses caused by taking or
not taking such action.

			
	SECTION 6.06	 	Limitations on Suits.

          Subject to Section 6.07 hereof, a Holder of a Security of any series may pursue a remedy with
respect to this Indenture or the Securities of such series or any related Guarantees only if:

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

     (2) the Holders of at least 25% in principal amount of the then outstanding Securities
of such series make a written request to the Trustee to pursue the remedy;

30

 

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

     (4) the Trustee does not comply with the request within 15 days after receipt of the
request and the offer of indemnity; and

     (5) during such 15-day period the Holders of a majority in principal amount of the
Securities of that series do not give the Trustee a direction inconsistent with the request.

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

			
	SECTION 6.07	 	Rights of Holders to Receive Payment.

          Notwithstanding any other provision of this Indenture, the right of any Holder of a Security
to receive payment of principal of and premium, if any, and interest on and any Additional Amounts
with respect to the Security, on or after the respective due dates expressed in the Security, or to
bring suit for the enforcement of any such payment on or after such respective dates, is absolute
and unconditional and shall not be impaired or affected without the consent of the Holder.

			
	SECTION 6.08	 	Collection Suit by Trustee.

          If an Event of Default specified in clause (1) or (2) of Section 6.01 hereof occurs and is
continuing, the Trustee is authorized to recover judgment in its own name and as trustee of an
express trust against the Company or a Subsidiary Guarantor for the amount of principal, premium
(if any), interest and any Additional Amounts remaining unpaid on the Securities of the series
affected by the Event of Default, and interest on overdue principal and premium, if any, and, to
the extent lawful, interest on overdue interest, and such further amount as shall be sufficient to
cover the costs and expenses of collection, including the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel.

			
	SECTION 6.09	 	Trustee May File Proofs of Claim.

          The Trustee is authorized to file such proofs of claim and other papers or documents and to
take such actions, including participating as a member, voting or otherwise, of any committee of
creditors, as may be necessary or advisable to have the claims of the Trustee (including any claim
for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel) and the Holders allowed in any judicial proceedings relative to the Company or a
Subsidiary Guarantor or their respective creditors or properties and shall be entitled and
empowered to collect, receive and distribute any money or other property payable or deliverable on
any such claims and any Bankruptcy Custodian in any such judicial proceeding is hereby authorized
by each Holder to make such payments to the Trustee, and in the event that the Trustee shall
consent to the making of such payments directly to the Holders, to pay to the Trustee any amount
due to it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its
agents and counsel, and any other amounts due the Trustee under Section 7.07. To the extent that
the payment of any such compensation, expenses, disbursements

31

 

and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee
under Section 7.07 out of the estate in any such proceeding, shall be denied for any reason,
payment of the same shall be secured by a lien on, and shall be paid out of, any and all
distributions, dividends, money, securities and other properties which the Holders of the
Securities may be entitled to receive in such proceeding whether in liquidation or under any plan
of reorganization or arrangement or otherwise. Nothing herein contained shall be deemed to
authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any
plan of reorganization, arrangement, adjustment or composition affecting the Securities or the
rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any
Holder in any such proceeding.

			
	SECTION 6.10	 	Priorities.

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

     First: to the Trustee for amounts due under Section 7.07;

     Second: to Holders for amounts due and unpaid on the Securities in respect of which or
for the benefit of which such money has been collected, for principal, premium (if any),
interest and any Additional Amounts ratably, without preference or priority of any kind,
according to the amounts due and payable on such Securities for principal, premium (if any),
interest and any Additional Amounts, respectively; and

     Third: to the Company.

          The Trustee, upon prior written notice to the Company, may fix record dates and payment dates
for any payment to Holders pursuant to this Article VI.

          To the fullest extent allowed under applicable law, if for the purpose of obtaining a judgment
against the Company or a Subsidiary Guarantor in any court it is necessary to convert the sum due
in respect of the principal of, premium (if any) or interest on or Additional Amounts with respect
to the Securities of any series (the “Required Currency”) into a currency in which a judgment will
be rendered (the “Judgment Currency”), the rate of exchange used shall be the rate at which in
accordance with normal banking procedures the Trustee could purchase in The City of New York the
Required Currency with the Judgment Currency on the Business Day in The City of New York next
preceding that on which final judgment is given. None of the Company, any Subsidiary Guarantor or
the Trustee shall be liable for any shortfall nor shall it benefit from any windfall in payments to
Holders of Securities under this Section 6.10 caused by a change in exchange rates between the time
the amount of a judgment against it is calculated as above and the time the Trustee converts the
Judgment Currency into the Required Currency to make payments under this Section 6.10 to Holders of
Securities, but payment of such judgment shall discharge all amounts owed by the Company and the
Subsidiary Guarantors on the claim or claims underlying such judgment.

32

 

			
	SECTION 6.11	 	Undertaking for Costs.

          In any suit for the enforcement of any right or remedy under this Indenture or in any suit
against the Trustee for any action taken or omitted by it as a trustee, a court in its discretion
may require the filing by any party litigant in the suit of an undertaking to pay the costs of the
suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys’
fees, against any party litigant in the suit, having due regard to the merits and good faith of the
claims or defenses made by the party litigant. This Section 6.11 does not apply to a suit by the
Trustee, a suit by a Holder pursuant to Section 6.07, or a suit by a Holder or Holders of more than
10% in principal amount of the then outstanding Securities of any series.

ARTICLE VII

TRUSTEE

			
	SECTION 7.01	 	Duties of Trustee.

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

          (b) Except during the continuance of an Event of Default with respect to the Securities of any
series:

     (1) the Trustee need perform only those duties that are specifically set forth in this
Indenture and no others, 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, the Trustee shall examine such certificates and opinions to determine
whether, on their face, they appear to conform to the requirements of this Indenture.

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

     (1) this paragraph does not limit the effect of Section 7.01(b);

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

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

33

 

          (d) Whether or not therein expressly so provided, every provision of this Indenture that in
any way relates to the Trustee is subject to the provisions of this Section 7.01.

          (e) No provision of this Indenture shall require the Trustee to expend or risk its own funds
or incur any liability. The Trustee may refuse to perform any duty or exercise any right or power
unless it receives indemnity satisfactory to it against any loss, liability or expense.

          (f) The Trustee shall not be liable for interest on any money received by it except as the
Trustee may agree in writing with the Company and the Subsidiary Guarantors. Money held in trust
by the Trustee need not be segregated from other funds except to the extent required by law. All
money received by the Trustee shall, until applied as herein provided, be held in trust for the
payment of the principal of, premium (if any) and interest on and Additional Amounts with respect
to the Securities.

			
	SECTION 7.02	 	Rights of Trustee.

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

          (b) Before the Trustee acts or refrains from acting, it may require instruction, an Officers’
Certificate or an Opinion of Counsel or both to be provided. The Trustee shall not be liable for
any action it takes or omits to take in good faith in reliance on such instruction, Officers’
Certificate or Opinion of Counsel. The Trustee may consult at the Company’s expense with counsel
of its selection and the written advice of such counsel or any Opinion of Counsel shall be full and
complete authorization and protection in respect of any action taken, suffered or omitted by it
hereunder in good faith and in reliance thereon.

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

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

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

			
	SECTION 7.03	 	May Hold Securities.

          The Trustee in its individual or any other capacity may become the owner or pledgee of
Securities and may otherwise deal with the Company, any Subsidiary Guarantor or any of their
respective Affiliates with the same rights it would have if it were not Trustee. Any Agent may do
the same with like rights and duties. However, the Trustee is subject to Sections 7.10 and 7.11.

34

 

			
	SECTION 7.04	 	Trustee’s Disclaimer.

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

			
	SECTION 7.05	 	Notice of Defaults.

          If a Default or Event of Default with respect to the Securities of any series occurs and is
continuing and it is known to the Trustee, the Trustee shall mail to Holders of Securities of such
series a notice of the Default or Event of Default within 30 days after it occurs. Except in the
case of a Default or Event of Default in payment of principal of, premium (if any) and interest on
and Additional Amounts or any sinking fund installment with respect to the Securities of such
series, the Trustee may withhold the notice if and so long as a committee of its Responsible
Officers in good faith determines that withholding the notice is in the interests of Holders of
Securities of such series.

			
	SECTION 7.06	 	Reports by Trustee to Holders.

          Within 60 days after each May 15 of each year after the execution of this Indenture, the
Trustee shall mail to Holders of a series, the Subsidiary Guarantors and the Company a brief report
dated as of such reporting date that complies with TIA § 313(a); provided, however, that if no
event described in TIA § 313(a) has occurred within the twelve months preceding the reporting date
with respect to a series, no report need be transmitted to Holders of such series. The Trustee
also shall comply with TIA § 313(b). The Trustee shall also transmit by mail all reports if and as
required by TIA §§ 313(c) and 313(d).

          A copy of each report at the time of its mailing to Holders of a series of Securities shall be
filed by the Company or a Subsidiary Guarantor with the SEC and each securities exchange, if any,
on which the Securities of such series are listed. The Company shall notify the Trustee if and when
any series of Securities is listed on any securities exchange.

			
	SECTION 7.07	 	Compensation and Indemnity.

          The Company agrees to pay to the Trustee for its acceptance of this Indenture and services
hereunder such compensation as the Company and the Trustee shall from time to time agree in
writing. The Trustee’s compensation shall not be limited by any law on compensation of a trustee of
an express trust. The Company agrees to reimburse the Trustee upon request for all reasonable
disbursements, advances and expenses incurred by it. Such expenses shall include the reasonable
compensation, disbursements and expenses of the Trustee’s agents and counsel.

          The Company hereby indemnifies the Trustee and any predecessor Trustee against any and all
loss, liability, damage, claim or expense, including taxes (other than taxes based upon, measured
by or determined by the income of the Trustee), incurred by it arising out

35

 

of or in connection with the acceptance or administration of its duties under this Indenture,
except as set forth in the next following paragraph. The Trustee shall notify the Company and the
Subsidiary Guarantors promptly of any claim for which it may seek indemnity. Failure by the
Trustee to so notify the Company shall not relieve the Company or the Subsidiary Guarantors of
their obligations hereunder. The Company shall defend the claim and the Trustee shall cooperate in
the defense. The Trustee may have separate counsel and the Company shall pay the reasonable fees
and expenses of such counsel. The Company need not pay for any settlement made without its
consent.

          The Company shall not be obligated to reimburse any expense or indemnify against any loss or
liability incurred by the Trustee through the Trustee’s negligence or bad faith.

          To secure the payment obligations of the Company in this Section 7.07, the Trustee shall have
a lien prior to the Securities on all money or property held or collected by the Trustee, except
that held in trust to pay principal of, premium (if any) and interest on and any Additional Amounts
with respect to Securities of any series. Such lien and the Company’s obligations under this
Section 7.07 shall survive the satisfaction and discharge of this Indenture.

          When the Trustee incurs expenses or renders services after an Event of Default specified in
Section 6.01(5) or (6) occurs, the expenses and the compensation for the services (including the
fees and expenses of its agents and counsel) are intended to constitute expenses of administration
under any Bankruptcy Law.

			
	SECTION 7.08	 	Replacement of Trustee.

          A resignation or removal of the Trustee and appointment of a successor Trustee shall become
effective only upon the successor Trustee’s acceptance of appointment as provided in this Section
7.08.

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

     (1) the Trustee fails to comply with Section 7.10;

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

     (3) a Bankruptcy Custodian or public officer takes charge of the Trustee or its
property; or

     (4) the Trustee otherwise becomes incapable of acting.

          If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any
reason, with respect to the Securities of one or more series, the Company shall promptly appoint a
successor Trustee or Trustees with respect to the Securities of that or those series (it

36

 

being understood that any such successor Trustee may be appointed with respect to the
Securities of one or more or all of such series and that at any time there shall be only one
Trustee with respect to the Securities of any particular series). Within one year after the
successor Trustee with respect to the Securities of any series takes office, the Holders of a
majority in principal amount of the Securities of such series then outstanding may appoint a
successor Trustee to replace the successor Trustee appointed by the Company.

          If a successor Trustee with respect to the Securities of any series does not take office
within 30 days after the retiring or removed Trustee resigns or is removed, the retiring or removed
Trustee, the Company, any Subsidiary Guarantor or the Holders of at least 10% in principal amount
of the then outstanding Securities of such series may petition any court of competent jurisdiction
for the appointment of a successor Trustee with respect to the Securities of such series.

          If the Trustee with respect to the Securities of a series fails to comply with Section 7.10,
any Holder of Securities of such series may petition any court of competent jurisdiction for the
removal of the Trustee and the appointment of a successor Trustee with respect to the Securities of
such series.

          In case of the appointment of a successor Trustee with respect to all Securities, each such
successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee, to
the Company and to the Subsidiary Guarantors. Thereupon the resignation or removal of the retiring
Trustee shall become effective, and the successor Trustee shall have all the rights, powers and
duties of the retiring Trustee under this Indenture. The successor Trustee shall mail a notice of
its succession to Holders. The retiring Trustee shall promptly transfer all property held by it as
Trustee to the successor Trustee, subject to the lien provided for in Section 7.07.

          In case of the appointment of a successor Trustee with respect to the Securities of one or
more (but not all) series, the Company, the Subsidiary Guarantors, the retiring Trustee and each
successor Trustee with respect to the Securities of one or more (but not all) series shall execute
and deliver an indenture supplemental hereto in which each successor Trustee shall accept such
appointment and that (1) shall confer to each successor Trustee all the rights, powers and duties
of the retiring Trustee with respect to the Securities of that or those series to which the
appointment of such successor Trustee relates, (2) if the retiring Trustee is not retiring with
respect to all Securities, shall confirm that all the rights, powers and duties of the retiring
Trustee with respect to the Securities of that or those series as to which the retiring Trustee is
not retiring shall continue to be vested in the retiring Trustee and (3) shall add to or change any
of the provisions of this Indenture as shall be necessary to provide for or facilitate the
administration of the trusts hereunder by more than one Trustee. Nothing herein or in such
supplemental indenture shall constitute such Trustees co-trustees of the same trust, and each such
Trustee shall be trustee of a trust or trusts hereunder separate and apart from any trust or trusts
hereunder administered by any other such Trustee. Upon the execution and delivery of such
supplemental indenture, the resignation or removal of the retiring Trustee shall become effective
to the extent provided therein and each such successor Trustee shall have all the rights, powers
and duties of the retiring Trustee with respect to the Securities of that or those series to which
the appointment of such successor Trustee relates. On request of the Company or any successor
Trustee, such retiring

37

 

Trustee shall transfer to such successor Trustee all property held by such retiring Trustee as
Trustee with respect to the Securities of that or those series to which the appointment of such
successor Trustee relates.

          Notwithstanding replacement of the Trustee or Trustees pursuant to this Section 7.08, the
obligations of the Company under Section 7.07 shall continue for the benefit of the retiring
Trustee or Trustees.

			
	SECTION 7.09	 	Successor Trustee by Merger, etc.

          Subject to Section 7.10, if the Trustee consolidates, merges or converts into, or transfers
all or substantially all of its corporate trust business to, another corporation, the successor
corporation without any further act shall be the successor Trustee.

          In case any Securities shall have been authenticated, but not delivered, by the Trustee then
in office, any successor by merger, conversion or consolidation to such authenticating Trustee may
adopt such authentication and deliver the Securities so authenticated; 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 to
the 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.

			
	SECTION 7.10	 	Eligibility; Disqualification.

          There shall at all times be a Trustee hereunder which shall be a corporation or banking or
trust company or association organized and doing business under the laws of the United States, any
State thereof or the District of Columbia and authorized under such laws to exercise corporate
trust power, shall be subject to supervision or examination by Federal or State (or the District of
Columbia) authority and shall have, or be a subsidiary of a bank or bank holding company having, a
combined capital and surplus of at least $50 million as set forth in its most recent published
annual report of condition.

          The Indenture shall always have a Trustee who satisfies the requirements of TIA §§ 310(a)(1),
310(a)(2) and 310(a)(5). The Trustee is subject to and shall comply with the provisions of TIA §
310(b) during the period of time required by this Indenture. Nothing in this Indenture shall
prevent the Trustee from filing with the SEC the application referred to in the penultimate
paragraph of TIA § 310(b).

			
	SECTION 7.11	 	Preferential Collection of Claims Against the Company or a Subsidiary Guarantor.

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

ARTICLE VIII

DISCHARGE OF INDENTURE

			
	SECTION 8.01	 	Termination of the Company’s and the Subsidiary Guarantors’ Obligations.

          (a) This Indenture shall cease to be of further effect with respect to the Securities of a
series (except that the Company’s obligations under Section 7.07, the Trustee’s and Paying Agent’s
obligations under Section 8.03 and the rights, powers, protections and privileges accorded the
Trustee under Article VII shall survive), and the Trustee, on demand of the Company, shall execute
proper instruments acknowledging the satisfaction and discharge of this Indenture with respect to
the Securities of such series, when:

          (1) either:

     (A) all outstanding Securities of such series theretofore authenticated and
issued (other than destroyed, lost or stolen Securities that have been replaced or
paid) have been delivered to the Trustee for cancellation; or

     (B) all outstanding Securities of such series not theretofore delivered to the
Trustee for cancellation:

	 	(i)	 	have become due and payable, or
	 
	 	(ii)	 	will become due and payable at
their Stated Maturity within one year, or
	 
	 	(iii)	 	are to be called for redemption
within one year under arrangements satisfactory to the Trustee
for the giving of notice of redemption by the Trustee in the
name, and at the expense, of the Company,

and, in the case of clause (i), (ii) or (iii) above, the Company or a Subsidiary
Guarantor has irrevocably deposited or caused to be deposited with the Trustee as
funds (immediately available to the Holders in the case of clause (i)) in trust for
such purpose (x) cash in an amount, or (y) Government Obligations, maturing as to
principal and interest at such times and in such amounts as will ensure the
availability of cash in an amount or (z) a combination thereof, which will be
sufficient, in the opinion (in the case of clauses (y) and (z)) of a nationally
recognized firm of independent public accountants expressed in a written
certification thereof delivered to the Trustee, to pay and discharge the entire
indebtedness on the Securities of such series for principal and interest to the date
of such deposit (in the case of Securities which have become due and payable) or for
principal, premium, if any, and interest to the Stated Maturity or Redemption Date,
as the case may be; or

39

 

     (C) the Company and the Subsidiary Guarantors have properly fulfilled such
other means of satisfaction and discharge as is specified, as contemplated by
Section 2.01, to be applicable to the Securities of such series;

     (2) the Company or a Subsidiary Guarantor has paid or caused to be paid all other sums
payable by them hereunder with respect to the Securities of such series; and

     (3) the Company has delivered to the Trustee an Officers’ Certificate stating that all
conditions precedent to satisfaction and discharge of this Indenture with respect to the
Securities of such series have been complied with, together with an Opinion of Counsel to
the same effect.

          (b) Unless this Section 8.01(b) is specified as not being applicable to Securities of a series
as contemplated by Section 2.01, the Company may, at its option, terminate certain of its and the
Subsidiary Guarantors’ respective obligations under this Indenture (“covenant defeasance”) with
respect to the Securities of a series if:

     (1) the Company or a Subsidiary Guarantor has irrevocably deposited or caused to be
irrevocably deposited with the Trustee as trust funds in trust for the purpose of making the
following payments, specifically pledged as security for and dedicated solely to the benefit
of the Holders of Securities of such series, (i) money in the currency in which payment of
the Securities of such series is to be made in an amount, or (ii) Government Obligations
with respect to such series, maturing as to principal and interest at such times and in such
amounts as will ensure the availability of money in the currency in which payment of the
Securities of such series is to be made in an amount or (iii) a combination thereof, that is
sufficient, in the opinion (in the case of clauses (ii) and (iii)) of a nationally
recognized firm of independent public accountants expressed in a written certification
thereof delivered to the Trustee, to pay the principal of and premium (if any) and interest
on all Securities of such series on each date that such principal, premium (if any) or
interest is due and payable and (at the Stated Maturity thereof or upon redemption as
provided in Section 8.01(e)) to pay all other sums payable by it hereunder; provided that
the Trustee shall have been irrevocably instructed to apply such money and/or the proceeds
of such Government Obligations to the payment of said principal, premium (if any) and
interest with respect to the Securities of such series as the same shall become due;

     (2) the Company has delivered to the Trustee an Officers’ Certificate stating that all
conditions precedent to satisfaction and discharge of this Indenture with respect to the
Securities of such series have been complied with, and an Opinion of Counsel to the same
effect;

     (3) no Default or Event of Default with respect to the Securities of such series shall
have occurred and be continuing on the date of such deposit;

     (4) the Company shall have delivered to the Trustee an Opinion of Counsel from a
nationally recognized counsel acceptable to the Trustee or a tax ruling to the effect that
the Holders will not recognize income, gain or loss for U.S. Federal income tax

40

 

purposes as a result of the Company’s exercise of its option under this Section 8.01(b)
and will be subject to U.S. Federal income tax on the same amount and in the same manner and
at the same times as would have been the case if such option had not been exercised;

     (5) the Company and the Subsidiary Guarantors have complied with any additional
conditions specified pursuant to Section 2.01 to be applicable to the discharge of
Securities of such series pursuant to this Section 8.01; and

     (6) such deposit and discharge shall not cause the Trustee to have a conflicting
interest as defined in TIA § 310(b).

          In such event, this Indenture shall cease to be of further effect (except as set forth in this
paragraph), and the Trustee, on demand of the Company, shall execute proper instruments
acknowledging satisfaction and discharge under this Indenture. However, the Company’s and the
Subsidiary Guarantors’ respective obligations in Sections 2.05, 2.06, 2.07, 2.08, 2.09, 4.01, 4.02,
7.07, 7.08 and 8.04, the Trustee’s and Paying Agent’s obligations in Section 8.03 and the rights,
powers, protections and privileges accorded the Trustee under Article VII shall survive until all
Securities of such series are no longer outstanding. Thereafter, only the Company’s obligations in
Section 7.07 and the Trustee’s and Paying Agent’s obligations in Section 8.03 shall survive with
respect to Securities of such series.

          After such irrevocable deposit made pursuant to this Section 8.01(b) and satisfaction of the
other conditions set forth herein, the Trustee upon request shall acknowledge in writing the
discharge of the Company’s and the Subsidiary Guarantors’ obligations under this Indenture with
respect to the Securities of such series except for those surviving obligations specified above.

          In order to have money available on a payment date to pay principal of or premium (if any) or
interest on the Securities, the Government Obligations shall be payable as to principal or interest
on or before such payment date in such amounts as will provide the necessary money. Government
Obligations shall not be callable at the issuer’s option.

          (c) If the Company and the Subsidiary Guarantors have previously complied or is concurrently
complying with Section 8.01(b) (other than any additional conditions specified pursuant to Section
2.01 that are expressly applicable only to covenant defeasance) with respect to Securities of a
series, then, unless this Section 8.01(c) is specified as not being applicable to Securities of
such series as contemplated by Section 2.01, the Company may elect that its and the Subsidiary
Guarantors’ respective obligations to make payments with respect to Securities of such series be
discharged (“legal defeasance”), if:

     (1) no Default or Event of Default under clauses (5) and (6) of Section 6.01 hereof
shall have occurred at any time during the period ending on the 91st day after the date of
deposit contemplated by Section 8.01(b) (it being understood that this condition shall not
be deemed satisfied until the expiration of such period);

     (2) unless otherwise specified with respect to Securities of such series as
contemplated by Section 2.01, the Company has delivered to the Trustee an Opinion of

41

 

Counsel from a nationally recognized counsel acceptable to the Trustee to the effect
referred to in Section 8.01(b)(4) with respect to such legal defeasance, which opinion is
based on (i) a private ruling of the Internal Revenue Service addressed to the Company, (ii)
a published ruling of the Internal Revenue Service pertaining to a comparable form of
transaction or (iii) a change in the applicable federal income tax law (including
regulations) after the date of this Indenture;

     (3) the Company and the Subsidiary Guarantors have complied with any other conditions
specified pursuant to Section 2.01 to be applicable to the legal defeasance of Securities of
such series pursuant to this Section 8.01(c); and

     (4) the Company has delivered to the Trustee a Company Request requesting such legal
defeasance of the Securities of such series and an Officers’ Certificate stating that all
conditions precedent with respect to such legal defeasance of the Securities of such series
have been complied with, together with an Opinion of Counsel to the same effect.

          In such event, the Company and the Subsidiary Guarantors will be discharged from its
obligations under this Indenture and the Securities of such series to pay principal of, premium (if
any) and interest on and any Additional Amounts with respect to Securities of such series, the
Company’s and the Subsidiary Guarantors’ respective obligations under Sections 4.01, 4.02 and 10.1
shall terminate with respect to such Securities, and the entire indebtedness of the Company
evidenced by such Securities and of the Subsidiary Guarantors evidenced by the related Guarantee
shall be deemed paid and discharged.

          (d) If and to the extent additional or alternative means of satisfaction, discharge or
defeasance of Securities of a series are specified to be applicable to such series as contemplated
by Section 2.01, each of the Company and the Subsidiary Guarantors may terminate any or all of its
obligations under this Indenture with respect to Securities of a series and any or all of its
obligations under the Securities of such series if it fulfills such other means of satisfaction and
discharge as may be so specified, as contemplated by Section 2.01, to be applicable to the
Securities of such series.

          (e) If Securities of any series subject to subsections (a), (b), (c) or (d) of this Section
8.01 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 provisions, the terms of
the applicable trust arrangement shall provide for such redemption, and the Company shall make such
arrangements as are reasonably satisfactory to the Trustee for the giving of notice of redemption
by the Trustee in the name, and at the expense, of the Company.

			
	SECTION 8.02	 	Application of Trust Money.

          The Trustee or a trustee satisfactory to the Trustee and the Company shall hold in trust money
or Government Obligations deposited with it pursuant to Section 8.01 hereof. It shall apply the
deposited money and the money from Government Obligations through the Paying Agent and in
accordance with this Indenture to the payment of principal of, premium (if

42

 

any) and interest on and any Additional Amounts with respect to the Securities of the series
with respect to which the deposit was made.

			
	SECTION 8.03	 	Repayment to Company.

          The Trustee and the Paying Agent shall promptly pay to the Company or any Subsidiary Guarantor
any excess money or Government Obligations (or proceeds therefrom) held by them at any time upon
the written request of the Company.

          Subject to the requirements of any applicable abandoned property laws, the Trustee and the
Paying Agent shall pay to the Company upon written request any money held by them for the payment
of principal, premium (if any), interest or any Additional Amounts that remain unclaimed for two
years after the date upon which such payment shall have become due. After payment to the Company,
Holders entitled to the money must look to the Company for payment as general creditors unless an
applicable abandoned property law designates another Person, and all liability of the Trustee and
the Paying Agent with respect to such money shall cease.

			
	SECTION 8.04	 	Reinstatement.

          If the Trustee or the Paying Agent is unable to apply any money or Government Obligations
deposited with respect to Securities of any series in accordance with Section 8.01 by reason of any
legal proceeding or by reason of any order or judgment of any court or governmental authority
enjoining, restraining or otherwise prohibiting such application, the obligations of the Company
and the Subsidiary Guarantors under this Indenture with respect to the Securities of such series
and under the Securities of such series shall be revived and reinstated as though no deposit had
occurred pursuant to Section 8.01 until such time as the Trustee or the Paying Agent is permitted
to apply all such money or Government Obligations in accordance with Section 8.01; provided,
however, that if the Company or any Subsidiary Guarantor has made any payment of principal of,
premium (if any) or interest on or any Additional Amounts with respect to any Securities because of
the reinstatement of its obligations, the Company or such Subsidiary Guarantor, as the case may be,
shall be subrogated to the rights of the Holders of such Securities to receive such payment from
the money or Government Obligations held by the Trustee or the Paying Agent.

ARTICLE IX

SUPPLEMENTAL INDENTURES AND AMENDMENTS

			
	SECTION 9.01	 	Without Consent of Holders.

          The Company, the Subsidiary Guarantors and the Trustee may amend or supplement this Indenture

this Indenture under the TIA;

     (6) to add to the covenants of the Company or any Subsidiary Guarantor for the benefit

being included solely for the benefit of such series), or to surrender any right or power
herein conferred upon the Company or any Subsidiary Guarantor;

     (7) to add any additional Events of Default with respect to all or any series of the
Securities (and, if any Event of Default is applicable to less than all series of
Securities, specifying the series to which such Event of Default is applicable);

     (8) to change or eliminate any of the provisions of this Indenture; provided that any
such change or elimination shall become effective only when there is no outstanding Security
of any series created prior to the execution of such amendment or supplemental indenture
that is adversely affected in any material respect by such change in or elimination of such
provision; provided, further, that any change made solely to conform the provisions of this
Indenture to the description of any Security in a prospectus supplement pursuant to which
such Securities were offered and sold will not be deemed to adversely affect any Security of
that series in any material respect;

     (9) to establish the form or terms of Securities of any series as permitted by Section
2.01;

     (10) to supplement any of the provisions of this Indenture to such extent as shall be
necessary to permit or facilitate the defeasance and discharge of any series of Securities
pursuant to Section 8.01; provided, however, that any such action shall not adversely affect
the interest of the Holders of Securities of such series or any other series of Securities
in any material respect; or

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

          Upon the request of the Company, accompanied by a Board Resolution, and upon receipt by the
Trustee of the documents described in Section 9.06, the Trustee shall, subject to Section 9.06,
join with the Company and the Subsidiary Guarantors in the execution of any

44

 

supplemental indenture authorized or permitted by the terms of this Indenture and make any
further appropriate agreements and stipulations that may be therein contained.

          Notwithstanding anything to the contrary in this Section 9.01, it shall not be necessary for
any Subsidiary Guarantor to join with the Company and the Trustee in the execution of any
supplemental indenture authorized or permitted by the terms of this Indenture unless such
supplemental indenture applies to a series of Securities entitled to the benefit of a Guarantee by
such Subsidiary Guarantor.

			
	SECTION 9.02	 	With Consent of Holders.

          Except as provided below in this Section 9.02, the Company, the Subsidiary Guarantors and the
Trustee may amend or supplement this Indenture with the written consent (including consents
obtained in connection with a tender offer or exchange offer for Securities of any one or more
series or all series or a solicitation of consents in respect of Securities of any one or more
series or all series, provided that in each case such offer or solicitation is made to all Holders
of then outstanding Securities of each such series (but the terms of such offer or solicitation may
vary from series to series)) of the Holders of at least a majority in principal amount of the then
outstanding Securities of each series affected by such amendment or supplement.

          Upon the request of the Company, accompanied by a Board Resolution, and upon the filing with
the Trustee of evidence of the consent of the Holders as aforesaid, and upon receipt by the Trustee
of the documents described in Section 9.06, the Trustee shall, subject to Section 9.06, join with
the Company and the Subsidiary Guarantors in the execution of such amendment or supplemental
indenture.

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

          The Holders of a majority in principal amount of the then outstanding Securities of one or
more series may waive compliance in a particular instance by the Company or any Subsidiary
Guarantor with any provision of this Indenture with respect to Securities of such series (including
waivers obtained in connection with a tender offer or exchange offer for Securities of such series
or a solicitation of consents in respect of Securities of such series, provided that in each case
such offer or solicitation is made to all Holders of then outstanding Securities of such series
(but the terms of such offer or solicitation may vary from series to series)).

          However, without the consent of each Holder affected, an amendment, supplement or waiver under
this Section 9.02 may not:

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

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

45

 

     (3) reduce the principal of, any premium on or any mandatory sinking fund payment with
respect to, or change the Stated Maturity of, any Security or reduce the amount of the
principal of an Original Issue Discount Security that would be due and payable upon a
declaration of acceleration of the Maturity thereof pursuant to Section 6.02;

     (4) reduce the premium, if any, payable upon the redemption of any Security or change
the time at which any Security may or shall be redeemed;

     (5) change any obligation of the Company or any Subsidiary Guarantor to pay Additional
Amounts with respect to any Security;

     (6) change the coin or currency or currencies (including composite currencies) in which
any Security or any premium, interest or Additional Amounts with respect thereto are
payable;

     (7) impair the right to institute suit for the enforcement of any payment of principal
of, premium (if any) or interest on or any Additional Amounts with respect to any Security
pursuant to Sections 6.07 and 6.08, except as limited by Section 6.06;

     (8) make any change in the percentage of principal amount of Securities necessary to
waive compliance with certain provisions of this Indenture pursuant to Section 6.04 or 6.07
or make any change in this sentence of Section 9.02;

     (9) waive a continuing Default or Event of Default in the payment of principal of,
premium (if any) or interest on or Additional Amounts with respect to the Securities; or

     (10) except as provided in Section 10.04, release any Subsidiary Guarantor or modify
the related Guarantee in any manner materially adverse to the Holders.

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

          The right of any Holder to participate in any consent required or sought pursuant to any
provision of this Indenture (and the obligation of the Company or any Subsidiary Guarantor to
obtain any such consent otherwise required from such Holder) may be subject to the requirement that
such Holder shall have been the Holder of record of any Securities with respect to which such
consent is required or sought as of a date identified by the Company or such Subsidiary Guarantor
in a notice furnished to Holders in accordance with the terms of this Indenture.

          After an amendment, supplement or waiver under this Section 9.02 becomes effective, the
Company shall mail to the Holders of each Security affected thereby a notice briefly describing the
amendment, supplement or waiver. Any failure of the Company to mail

46

 

such notice, or any defect therein, shall not, however, in any way impair or affect the
validity of any such amendment, supplement or waiver.

          Notwithstanding anything to the contrary in this Section 9.02, it shall not be necessary for
any Subsidiary Guarantor to join with the Company and the Trustee in the execution of any
supplemental indenture authorized or permitted by the terms of this Indenture unless such
supplemental indenture applies to a series of Securities entitled to the benefit of a Guarantee by
such Subsidiary Guarantor.

			
	SECTION 9.03	 	Compliance with Trust Indenture Act.

          Every amendment or supplement to this Indenture or the Securities shall comply in form and
substance with the TIA as then in effect.

			
	SECTION 9.04	 	Revocation and Effect of Consents.

          Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder is a
continuing consent by the Holder and every subsequent Holder of a Security or portion of a Security
that evidences the same debt as the consenting Holder’s Security, even if notation of the consent
is not made on any Security. However, any such Holder or subsequent Holder may revoke the consent
as to his or her Security or portion of a Security if the Trustee receives written notice of
revocation before a date and time therefor identified by the Company or any Subsidiary Guarantor in
a notice furnished to such Holder in accordance with the terms of this Indenture or, if no such
date and time shall be identified, the date the amendment, supplement or waiver becomes effective.
An amendment, supplement or waiver becomes effective in accordance with its terms and thereafter
binds every Holder.

          The Company or any Subsidiary Guarantor may, but shall not be obligated to, fix a record date
(which need not comply with TIA § 316(c)) for the purpose of determining the Holders entitled to
consent to any amendment, supplement or waiver or to take any other action under this Indenture.
If a record date is fixed, then notwithstanding the provisions of the immediately preceding
paragraph, those Persons who were Holders at such record date (or their duly designated proxies),
and only those Persons, shall be entitled to consent to such amendment, supplement or waiver or to
revoke any consent previously given, whether or not such Persons continue to be Holders after such
record date. No consent shall be valid or effective for more than 90 days after such record date
unless consents from Holders of the principal amount of Securities required hereunder for such
amendment or waiver to be effective shall have also been given and not revoked within such 90-day
period.

          After an amendment, supplement or waiver becomes effective, it shall bind every Holder, unless
it is of the type described in any of clauses (1) through (9) of Section 9.02 hereof. In such
case, the amendment, supplement or waiver shall bind each Holder who has consented to it and every
subsequent Holder that evidences the same debt as the consenting Holder’s Security.

			
	SECTION 9.05	 	Notation on or Exchange of Securities.

          If an amendment or supplement changes the terms of an outstanding Security, the Company may
require the Holder of the Security to deliver it to the Trustee. The Trustee may

47

 

place an appropriate notation on the Security at the request of the Company regarding the
changed terms and return it to the Holder. Alternatively, if the Company so determines, the
Company in exchange for the Security shall issue and the Trustee shall authenticate a new Security
that reflects the changed terms. Failure to make the appropriate notation or to issue a new
Security shall not affect the validity of such amendment or supplement.

          Securities of any series authenticated and delivered after the execution of any amendment or
supplement may, and shall if required by the Trustee, bear a notation in form approved by the
Trustee as to any matter provided for in such amendment or supplement.

			
	SECTION 9.06	 	Trustee to Sign Amendments, etc.

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

ARTICLE X

GUARANTEE

			
	SECTION 10.01	 	Guarantee.

          (a) Notwithstanding any provision of this Article X to the contrary, the provisions of this
Article X relating to the Subsidiary Guarantors shall be applicable only to, and inure solely to
the benefit of, the Securities of any series designated, pursuant to Section 2.01, as entitled to
the benefits of the related Guarantee of each of the Subsidiary Guarantors.

          (b) For value received, each of the Subsidiary Guarantors hereby fully, unconditionally and
absolutely guarantees (each, a “Guarantee”) to the Holders and to the Trustee the due and punctual
payment of the principal of, and premium, if any, and interest on the Securities and all other
amounts due and payable under this Indenture and the Securities by the Company, when and as such
principal, premium, if any, and interest shall become due and payable, whether at the Stated
Maturity or by declaration of acceleration, call for redemption or otherwise, according to the
terms of the Securities and this Indenture, subject to the limitations set forth in Section 10.03.

          (c) Failing payment when due of any amount guaranteed pursuant to the related Guarantee, for
whatever reason, each of the Subsidiary Guarantors will be jointly and severally obligated to pay
the same immediately. Each of the Guarantees hereunder is intended to be a general, unsecured,
senior obligation of the related Subsidiary Guarantor and will rank pari passu in right of payment
with all Debt of such Subsidiary Guarantor that is not, by its
terms, expressly subordinated in right of payment to such Guarantee. Each of the Subsidiary
Guarantors hereby agrees that its obligations hereunder shall be full, unconditional and absolute,

48

 

irrespective of the validity, regularity or enforceability of the Securities, its Guarantee, the
Guarantee of any other Subsidiary Guarantor or this Indenture, the absence of any action to enforce
the same, any waiver or consent by any Holder of the Securities with respect to any provisions
hereof or thereof, the recovery of any judgment against the Company or any Subsidiary Guarantor, or
any action to enforce the same or any other circumstances which might otherwise constitute a legal
or equitable discharge or defense of the Subsidiary Guarantors. Each of the Subsidiary Guarantors
hereby agrees that in the event of a default in payment of the principal of, or premium, if any, or
interest on the Securities of such series, whether at the Stated Maturity or by declaration of
acceleration, call for redemption or otherwise, legal proceedings may be instituted by the Trustee
on behalf of the Holders or, subject to Section 6.06, by the Holders, on the terms and conditions
set forth in this Indenture, directly against such Subsidiary Guarantor to enforce such Guarantee
without first proceeding against the Company or any other Subsidiary Guarantor.

          (d) The obligations of each of the Subsidiary Guarantors under this Article X shall be as
aforesaid full, unconditional and absolute and shall not be impaired, modified, released or limited
by any occurrence or condition whatsoever, including, without limitation, (i) any compromise,
settlement, release, waiver, renewal, extension, indulgence or modification of, or any change in,
any of the obligations and liabilities of the Company or any of the Subsidiary Guarantors contained
in the Securities or this Indenture, (ii) any impairment, modification, release or limitation of
the liability of the Company, any of the Subsidiary Guarantors or any of their estates in
bankruptcy, or any remedy for the enforcement thereof, resulting from the operation of any present
or future provision of any applicable Bankruptcy Law, as amended, or other statute or from the
decision of any court, (iii) the assertion or exercise by the Company, any of the Subsidiary
Guarantors or the Trustee of any rights or remedies under the Securities or this Indenture or their
delay in or failure to assert or exercise any such rights or remedies, (iv) the assignment or the
purported assignment of any property as security for the Securities, including all or any part of
the rights of the Company or any of the Subsidiary Guarantors under this Indenture, (v) the
extension of the time for payment by the Company or any of the Subsidiary Guarantors of any
payments or other sums or any part thereof owing or payable under any of the terms and provisions
of the Securities or this Indenture or of the time for performance by the Company or any of the
Subsidiary Guarantors of any other obligations under or arising out of any such terms and
provisions or the extension or the renewal of any thereof, (vi) the modification or amendment
(whether material or otherwise) of any duty, agreement or obligation of the Company or any of the
Subsidiary Guarantors set forth in this Indenture, (vii) the voluntary or involuntary liquidation,
dissolution, sale or other disposition of all or substantially all of the assets, marshaling of
assets and liabilities, receivership, insolvency, bankruptcy, assignment for the benefit of
creditors, reorganization, arrangement, composition or readjustment of, or other similar proceeding
affecting, the Company or any of the Subsidiary Guarantors or any of their respective assets, or
the disaffirmance of the Securities, the Guarantees or this Indenture in any such proceeding,
(viii) the release or discharge of the Company or any of the Subsidiary Guarantors from the
performance or observance of any agreement, covenant, term or condition contained in any of such
instruments by operation of law, (ix) the unenforceability of the Securities of such series, the
related Guarantees or this Indenture or (x) any other circumstances (other than payment in full or
discharge of all amounts guaranteed pursuant to the
related Guarantees) which might otherwise constitute a legal or equitable discharge of a
surety or guarantor.

49

 

          (e) Each of the Subsidiary Guarantors hereby (i) waives diligence, presentment, demand of
payment, filing of claims with a court in the event of the merger, insolvency or bankruptcy of the
Company or any of the Subsidiary Guarantors, and all demands whatsoever, (ii) acknowledges that any
agreement, instrument or document evidencing its Guarantee may be transferred and that the benefit
of its obligations hereunder shall extend to each holder of any agreement, instrument or document
evidencing its Guarantee without notice to it and (iii) covenants that its Guarantee will not be
discharged except by complete performance of such Guarantee. Each of the Subsidiary Guarantors
further agrees that if at any time all or any part of any payment theretofore applied by any Person
to its Guarantee is, or must be, rescinded or returned for any reason whatsoever, including,
without limitation, the insolvency, bankruptcy or reorganization of the Company or any of the
Subsidiary Guarantors, such Guarantee shall, to the extent that such payment is or must be
rescinded or returned, be deemed to have continued in existence notwithstanding such application,
and such Guarantee shall continue to be effective or be reinstated, as the case may be, as though
such application had not been made.

          (f) Each of the Subsidiary Guarantors shall be subrogated to all rights of the Holders and the
Trustee against the Company in respect of any amounts paid by such Subsidiary Guarantor pursuant to
the provisions of this Indenture; provided, however, that such Subsidiary Guarantor shall not be
entitled to enforce or to receive any payments arising out of, or based upon, such right of
subrogation until all of the Securities of such series and the related Guarantees shall have been
paid in full or discharged.

			
	SECTION 10.02	 	Execution and Delivery of Guarantees.

          To further evidence its Guarantee set forth in Section 10.01, each of the Subsidiary
Guarantors hereby agrees that a notation relating to such Guarantee, substantially in the form
attached hereto as Annex A, shall be endorsed on each Security of the series entitled to the
benefits of such Guarantee authenticated and delivered by the Trustee, which notation of Guarantee
shall be executed by either manual or facsimile signature of an Officer of such Subsidiary
Guarantor. Each of the Subsidiary Guarantors hereby agrees that its Guarantee set forth in Section
10.01 shall remain in full force and effect notwithstanding any failure to endorse on each Security
a notation relating to such Guarantee. If any Officer of such Subsidiary Guarantor whose signature
is on this Indenture or a notation of Guarantee no longer holds that office at the time the Trustee
authenticates such Security or at any time thereafter, the Guarantee of such Security shall be
valid nevertheless. The delivery of any Security of a series entitled to the benefits of a
Guarantee under this Article X by the Trustee, after the authentication thereof hereunder, shall
constitute due delivery of the Guarantee set forth in this Indenture on behalf of each Subsidiary
Guarantor.

			
	SECTION 10.03	 	Limitation on Liability of the Subsidiary Guarantors.

          Each Subsidiary Guarantor and by its acceptance hereof each Holder of a Security of a series
entitled to the benefits of a Guarantee under this Article X hereby confirms that it is the
intention of all such parties that the guarantee by such Subsidiary Guarantor pursuant to its
Guarantee not constitute a fraudulent transfer or conveyance for purposes of any federal or state
law. To effectuate the foregoing intention, the Holders of a Security entitled to the benefits of

50

 

such Guarantee and the Subsidiary Guarantors hereby irrevocably agree that the obligations of each
Subsidiary Guarantor under its Guarantee shall be limited to the maximum amount as will, after
giving effect to all other contingent and fixed liabilities of such Subsidiary Guarantor and to any
collections from or payments made by or on behalf of any other Subsidiary Guarantor in respect of
the obligations of such other Subsidiary Guarantor under its Guarantee, result in the obligations
of such Subsidiary Guarantor under its Guarantee not constituting a fraudulent conveyance or
fraudulent transfer under federal or state law.

			
	SECTION 10.04	 	Release of Subsidiary Guarantors from Guarantee.

          (a) Notwithstanding any other provisions of this Indenture, the Guarantee of any Subsidiary
Guarantor may be released upon the terms and subject to the conditions set forth in this Section
10.04. Provided that no Default shall have occurred and shall be continuing under this Indenture,
any Guarantee incurred by a Subsidiary Guarantor pursuant to this Article X shall be
unconditionally released and discharged (i) automatically upon (A) any sale, exchange or transfer,
whether by way of merger or otherwise, to any Person that is not an Affiliate of the Company, of
all of the Company’s direct or indirect equity interests in such Subsidiary Guarantor (provided
such sale, exchange or transfer is not prohibited by this Indenture) or (B) the merger of such
Subsidiary Guarantor into the Company or any other Subsidiary Guarantor or the liquidation and
dissolution of such Subsidiary Guarantor (in each case to the extent not prohibited by this
Indenture) or (ii) following delivery of a written notice of such release or discharge by the
Company to the Trustee, upon the release or discharge of all guarantees by such Subsidiary
Guarantor of any Debt of the Company other than obligations arising under this Indenture and any
Securities issued hereunder, except a discharge or release by or as a result of payment under such
guarantees.

          (b) The Trustee shall deliver an appropriate instrument evidencing any release of a Subsidiary
Guarantor from its Guarantee upon receipt of a written request of the Company accompanied by an
Officers’ Certificate and an Opinion of Counsel that the Subsidiary Guarantor is entitled to such
release in accordance with the provisions of this Indenture. If the Subsidiary Guarantor is not so
released it shall remain liable for the full amount of principal of (and premium, if any, on) and
interest on the Securities entitled to the benefits of such Guarantee as provided in this
Indenture, subject to the limitations of Section 10.03.

51

 

SECTION 10.05 Contribution. In order to provide for just and equitable contribution among the Subsidiary
Guarantors, the Subsidiary Guarantors hereby agree, inter se, that in the event any payment or
distribution is made by any Subsidiary Guarantor (a “Funding Guarantor”) under its Guarantee, such
Funding Guarantor shall be entitled to a contribution from each other Subsidiary Guarantor (as
applicable) in a pro rata amount based on the net assets of each Subsidiary Guarantor (including
the Funding Guarantor) for all payments, damages and expenses incurred by that Funding Guarantor in
discharging the Company’s obligations with respect to the Securities of a series entitled to the
benefits of a Guarantee under this Article X or any other Subsidiary Guarantor’s obligations with
respect to its Guarantee of such series of Securities.

     The Global Note shall represent such principal amount of the outstanding Notes as shall be
specified therein and shall provide that it shall represent the aggregate principal amount of
outstanding Notes from time to time endorsed thereon and that the aggregate principal amount of
outstanding Notes represented thereby may from time to time be increased or reduced to reflect
repurchases, conversions, transfers or exchanges permitted hereby. Any endorsement of the Global
Note to reflect the amount of any increase or decrease in the amount of outstanding Notes
represented thereby shall be made by the Trustee or the Custodian, at the direction of the Trustee,
in such manner and upon instructions given by the holder of such Notes in accordance with this
Supplemental Indenture. Payment of principal, accrued and unpaid interest and premium, if any
(including any Fundamental Change Repurchase Price, Repurchase Price or Redemption Price), on the
Global Note shall be made to the holder of such Note on the date of payment, unless a record date
or other means of determining holders eligible to receive payment is provided for herein.

     The terms and provisions contained in the form of Note attached as Exhibit A hereto shall
constitute, and are hereby expressly made, a part of this Supplemental Indenture.

     Section 2.03 Date and Denomination of Notes; Payments of Interest. The Notes shall be
issuable in registered form without coupons in denominations of $1,000 principal amount and
integral multiples thereof. Each Note shall be dated the date of its authentication and shall bear
interest from the date specified on the face of the form of Note attached as Exhibit A hereto.
Interest on the Notes shall be computed on the basis of a 360-day year comprised of twelve 30-day
months.

10

 

     The Person in whose name any Note (or its predecessor security) is registered on the Note
Register at the close of business on any Interest Record Date with respect to any Interest Payment
Date shall be entitled to receive the interest payable on such Interest Payment Date. Interest
shall be payable at the office or agency of the Company maintained by the Company for such purposes
in the United States, which shall initially be the office of the Trustee at 225 Asylum Street,
Hartford, CT 06103. The Company shall pay interest (a) on any Notes in certificated form by check
mailed to the address of the Person entitled thereto as it appears in the Note Register (or upon
written application by such Person to the Trustee and Paying Agent (if different from the Trustee)
not later than the relevant Interest Record Date, by wire transfer in immediately available funds
to such Person’s account within the United States, if such Person is entitled to interest on an
aggregate principal in excess of $1,000,000, which application shall remain in effect until the
Noteholder notifies the Trustee and Paying Agent to the contrary) or (b) on any Global Note by wire
transfer of immediately available funds to the account of the Depositary or its nominee.

     Section 2.04 Payments of Additional Interest. If required by Section 4.02, each Note shall
bear Additional Interest in the manner set forth herein. Whenever in this Supplemental Indenture
there is mentioned, in any context, the payment of the principal of, premium, if any, or interest
on, or in respect of, any Note, such mention shall be deemed to include mention of the payment of
“Additional Interest” provided for in Section 4.02 to the extent that, in such context, Additional
Interest is, was or would be payable in respect thereof and express mention of the payment of
Additional Interest (if applicable) in any provisions hereof shall not be construed as excluding
Additional Interest in those provisions hereof where such express mention is not made.

     Section 2.05 Exchange and Registration of Transfer of Notes; Depositary.

     (a) The Company shall cause to be kept at the corporate trust office a register (the register
maintained in such office or in any other office or agency of the Company designated pursuant to
Section 3.02 being herein sometimes collectively referred to as the “Note Register,” in which,
subject to such reasonable regulations as it may prescribe, the Company shall provide for the
registration of Notes and transfers of Notes. Such register shall be in written form or in any
form capable of being converted into written form within a reasonable period of time. The Trustee
is hereby appointed “Note Registrar” and shall constitute a Registrar (as such term is defined in
the Original Indenture) for the purpose of registering Notes and transfers of Notes as herein
provided. The Company may appoint one or more co-registrars in accordance with Section 3.02.

     Notes may be exchanged for other Notes of any authorized denominations and of a like aggregate
principal amount, upon surrender of the Notes to be exchanged at any such office or agency
maintained by the Company pursuant to Section 3.02. Whenever any Notes are so surrendered for
exchange, the Company shall execute, and the Trustee shall authenticate and deliver, the Notes that
the Noteholder making the exchange is entitled to receive, bearing registration numbers not
contemporaneously outstanding.

     None of the Company, the Trustee, the Note Registrar or any co-registrar shall be required to
exchange or register a transfer of (i) any Notes surrendered for conversion or, if a portion of any
Note is surrendered for conversion, such portion thereof surrendered for

11

 

conversion or (ii) any Notes, or a portion of any Note, surrendered for repurchase (and not
withdrawn) in accordance with Article 9 hereof.

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

     (b) The Company initially appoints The Depository Trust Company to act as Depositary with
respect to the Global Notes. So long as the Notes are eligible for book-entry settlement with the
Depositary, unless otherwise required by law, all Notes shall be represented by one or more Notes
in the form of Global Securities (each, a “Global Note”) registered in the name of the Depositary
or the nominee of the Depositary. The transfer and exchange of beneficial interests in a Global
Note that does not involve the issuance of a definitive Note, shall be effected through the
Depositary in accordance with this Supplemental Indenture and the procedures of the Depositary
therefor.

     Notwithstanding any other provisions of the Indenture (other than the provisions set forth in
this Section 2.05(b)), a Global Note may not be transferred as a whole or in part except (i) 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 and (ii) for transfers of portions of a Global
Note in certificated form made upon request of a member of, or a participant in, the Depositary
(for itself or on behalf of a beneficial owner) by written notice given to the Trustee by or on
behalf of the Depositary in accordance with customary procedures of the Depositary and in
compliance with this Section 2.05.

     The Depositary shall be a clearing agency registered under the Exchange Act. The Company
initially appoints The Depository Trust Company to act as Depositary with respect to the Global
Note. Initially, the Global Notes shall be issued to the Depositary, registered in the name of
Cede & Co., as the nominee of the Depositary, and deposited with the Trustee as Custodian for the
Depositary.

     If (i) the Depositary notifies the Company at any time that the Depositary is unwilling or
unable to continue as depositary for the Global Notes and a successor depositary is not appointed
within 90 calendar days, (ii) the Depositary ceases to be registered as a clearing agency under the
Exchange Act and a successor depositary is not appointed within 90 calendar days or (iii) an Event
of Default in respect of the Notes has occurred and is continuing, and any Noteholder has requested
that the Notes be issued in definitive form in exchange for a Global Note, the Company will
execute, and the Trustee, upon receipt of an Officers’ Certificate and a Company Order for the
authentication and delivery of Notes, will authenticate and deliver Notes in definitive form to
each person that the Depositary identifies as a beneficial owner of the related Notes (or a portion
thereof) in an aggregate principal amount equal to the principal amount of such Global Note, in
exchange for such Global Note, and upon delivery of the Global Note to the Trustee such Global Note
shall be canceled.

12

 

     Definitive Notes issued in exchange for all or a part of a Global Note pursuant to this
Section 2.05(b) shall be registered in such names and in such authorized denominations as the
Depositary, pursuant to instructions from its direct or indirect participants or otherwise, shall
instruct the Trustee. Upon execution and authentication, the Trustee shall deliver such definitive
Notes to the Persons in whose names such definitive Notes are so registered.

     At such time as all interests in a Global Note have been converted, canceled, redeemed,
repurchased or transferred, such Global Note shall be, upon receipt thereof, canceled by the
Trustee in accordance with standing procedures and instructions existing between the Depositary and
the Custodian. At any time prior to such cancellation, if any interest in a Global Note is
exchanged for definitive Notes, converted, canceled, repurchased or transferred to a transferee who
receives definitive Notes therefor or any definitive Note is exchanged or transferred for part of
such Global Note, the principal amount of such Global Note shall, in accordance with the standing
procedures and instructions existing between the Depositary and the Custodian, be appropriately
reduced or increased, as the case may be, and an endorsement shall be made on such Global Note, by
the Trustee or the Custodian, at the direction of the Trustee, to reflect such reduction or
increase.

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

     Section 2.06 CUSIP Numbers. The Company in issuing the Notes may use “CUSIP” numbers (if then
generally in use), and, if so, the Trustee shall use “CUSIP” numbers in all notices issued to
Noteholders as a convenience to holders of the Notes; provided, that any such notice may state that
no representation is made as to the correctness of such numbers either as printed on the Notes or
on such notice and that reliance may be placed only on the other identification numbers printed on
the Notes. The Company will promptly notify the Trustee in writing of any change in the “CUSIP”
numbers.

     Section 2.07 Additional Notes; Repurchases. The Company may, without the consent of the
Noteholders and notwithstanding Section 2.01, reopen this Supplemental Indenture and issue
additional Notes hereunder with the same terms and with the same CUSIP number as the Notes
initially issued hereunder in an unlimited aggregate principal amount, which will form the same
series with the Notes initially issued hereunder; provided that no such additional Notes will be
treated as part of the same series as the Notes unless such additional Notes will be part of the
same issue as the Notes initially issued hereunder for U.S. federal income tax purposes. Prior to
the issuance of any such additional Notes, the Company shall deliver to the Trustee a Company
Order, an Officers’ Certificate and an Opinion of Counsel, such Officers’ Certificate and Opinion
of Counsel to cover such matters, in addition to those required by Section 11.05 of the Original
Indenture, as the Trustee shall reasonably request. The Company may also from time to time
repurchase the Notes in open market purchases or negotiated transactions without prior notice to
Noteholders.

ARTICLE 3

Particular Covenants of the Company

13

 

     Section 3.01 Payment of Principal, Premium and Interest. The Company covenants and agrees
that it will cause to be paid the principal of and premium, if any (including the Fundamental
Change Repurchase Price, the Repurchase Price and the Redemption Price), and accrued and unpaid
interest on each of the Notes at the places, at the respective times and in the manner provided
herein and in the Notes. Each installment of interest on the Notes, may be paid by mailing checks
for the amount payable to Noteholders entitled thereto as they shall appear on the registry books
of the Company; provided that, with respect to any Noteholder with an aggregate principal amount in
excess of $1,000,000, at the application of such holder in writing to the Trustee and Paying Agent
(if different from the Trustee) not later than the relevant Interest Record Date, interest on such
holder’s Notes shall be paid by wire transfer in immediately available funds to such holder’s
account in the United States, which application shall remain in effect until the Noteholder
notifies the Trustee and Paying Agent to the contrary; provided further that payment of interest
made to the Depositary shall be paid by wire transfer in immediately available funds in accordance
with such wire transfer instructions and other procedures provided by the Depositary from time to
time.

     Section 3.02 Maintenance of Office or Agency. The Company will maintain in the United States,
an office or agency where the Notes may be surrendered for registration of transfer or exchange or
for presentation for payment, repurchase or redemption (“Paying Agent”) or for conversion
(“Conversion Agent”) and where notices and demands to or upon the Company in respect of the Notes
and the Indenture may be served. 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 or the office or agency of the Trustee.

     The Company may also from time to time designate as co-registrars one or more other offices or
agencies where the Notes may be presented or surrendered for any or all such purposes and may from
time to time rescind such designations; provided that no such designation or rescission shall in
any manner relieve the Company of its obligation to maintain an office or agency in the United
States, for such purposes. The Company will give prompt written notice to the Trustee of any such
designation or rescission and of any change in the location of any such other office or agency.
The terms “Paying Agent” and “Conversion Agent” include any such additional or other offices or
agencies, as applicable.

     The Company hereby initially designates the Trustee as the Paying Agent, Note Registrar,
Custodian, Bid Solicitation Agent and Conversion Agent and the corporate trust office and the
office or agency of the Trustee each shall be considered as one such office or agency of the
Company for each of the aforesaid purposes; provided that the Trustee may appoint an agent,
reasonably acceptable to the Company, to perform the duties of the Bid Solicitation Agent.

     Section 3.03 Existence. Except as permitted by Section 7.01 or Article V of the Original
Indenture, the Company will do or cause to be done all things necessary to preserve and keep in
full force and effect its corporate existence.

14

 

     Section 3.04 Additional Interest. If Additional Interest is payable by the Company, the
Company shall deliver to the Trustee an Officers’ Certificate to that effect stating (a) the amount
of such Additional Interest that is payable and (b) the date on which such interest is payable.
Unless and until a Responsible Officer of the Trustee receives at the corporate trust office such a
certificate, the Trustee may assume without inquiry that no such Additional Interest is payable.

     Section 3.05 Further Instruments and Acts. Upon request of the Trustee, the Company 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 Supplemental Indenture.

     Section 3.06 Reporting Obligations. Notwithstanding that the Company may not be subject to
the reporting requirements of Section 13 or 15(d) of the Exchange Act, the Company will file with
the Commission (unless the Commission will not accept such a filing) within the time periods
specified in the Exchange Act and, within 15 days of filing, or attempting to file, the same with
the Commission, furnish to the Trustee and the holders of the outstanding Notes:

     (a) all quarterly and annual financial and other information with respect to the Company and
its subsidiaries that would be required to be contained in a filing with the Commission on Forms
10-Q and 10-K if the Company were required to file such forms, including a “Management’s Discussion
and Analysis of Financial Condition and Results of Operations” and, with respect to the annual
information only, a report thereon by the Company’s certified independent accountants; and

     (b) all current reports that would be required to be filed with the Commission on Form 8-K if
the Company were required to file such reports.

     So long as the Company is required to file periodic reports under Section 13(a) or Section
15(d) of the Securities Exchange Act of 1934, as amended, the Company’s obligation to deliver the
information referred to above shall be deemed satisfied upon the filing of such information in the
EDGAR system and the giving of notice to the Trustee as to the public availability of such
information from such source.

     Section 3.07 Future Guarantors. If any Subsidiary of the Company that is not a Subsidiary
Guarantor guarantees or becomes a co-obligor with respect to any indebtedness for money borrowed of
the Company or another Subsidiary Guarantor, then such Subsidiary shall, within 15 days thereof,
execute a supplement to the Indenture under which it shall become a Subsidiary Guarantor with
respect to the Notes in accordance with the terms of Article 10 hereof and Article X of the
Original Indenture.

ARTICLE 4

Defaults and Remedies

     Section 4.01 Additional Events of Default; Modifications. In addition to those Events of
Default set forth in Section 6.01 of the Original Indenture, the following events shall be Events
of Default with respect to the Notes and the terms of the Original Indenture shall be modified as
set forth below:

15

 

     (a) failure by the Company to issue a notice with respect to a Fundamental Change when such
notice becomes due in accordance with Sections 8.03(d) or 9.02(b);

     (b) failure by the Company to comply with its obligations to repurchase the Notes as required
under Article 9, or failure by the Company to comply with its obligations to redeem the Notes under
Article 10 after the Company issues a notice of redemption in accordance with Section 3.03 of the
Original Indenture;

     (c) failure by the Company to deliver when due of all cash and any shares of Common Stock or
other consideration payable upon conversion with respect to the Notes, which failure continues for
10 days;

     (d) failure by the Company to comply with Section 7.01 hereof upon our receipt of notice of
such Default from the Trustee or from holders of not less than 25% in aggregate principal amount of
the Notes then outstanding, and the failure to cure (or obtain a waiver of) such Default within 30
days after receipt of such notice;

     (e) failure by any Subsidiary Guarantor to perform any covenant set forth in its Guarantee;
and

     (f) a default under any mortgage, indenture or instrument under which there may be issued or
by which there may be secured or evidenced any indebtedness for money borrowed by the Company or
any of its Subsidiaries (or the payment of which is guaranteed by the Company or any of its
Subsidiaries), which default is caused by a failure to pay principal of or premium or interest on
such indebtedness prior to the expiration of any grace period provided in such indebtedness,
including any extension thereof (a “payment default”), or results in the acceleration of such
indebtedness prior to its stated maturity and, in each case, the principal amount of any such
indebtedness, together with the principal amount of any other such indebtedness under which there
has been a payment default or the maturity of which has been so accelerated, aggregates in excess
of $25.0 million and provided, further, that if any such default is cured or waived or any such
acceleration rescinded, or such indebtedness is repaid, within a period of 10 days from the
continuation of such default beyond the applicable grace period or the occurrence of such
acceleration, as the case may be, such Event of Default and any consequential acceleration of the
Notes shall be automatically rescinded, so long as such rescission does not conflict with any
judgment or decree.

     Section 4.02 Sole Remedy for Failure to Report. Notwithstanding any other provision of the
Indenture, if the Company so elects, the sole remedy for an Event of Default relating to the
failure to comply with the reporting obligations under Section 3.06 will, for the period beginning
on the 91st calendar day after the written notice of the occurrence of such failure to report from
the Trustee or holders of 25% of the outstanding principal amount of the Notes, consist exclusively
of the right to receive additional interest on the Notes at a rate equal to 0.25% per annum of the
principal amount of the Notes (the “Additional Interest”). This Additional Interest will be
payable in the same manner and on the same dates as the stated interest payable on the Notes. If
the Company so elects, this Additional Interest will accrue on all outstanding Notes from and
including the 91st day following the date of such written notice of the failure to comply with
Section 3.06 to but not including the date on which the Event of Default relating to

16

 

the reporting obligations as set forth in Section 3.06 shall have been cured or waived. On
the 180th calendar day after the commencement of such Additional Interest (if such violation is not
cured or waived prior to such 180th calendar day), the Notes will be subject to acceleration upon
written notice from the Trustee or holders of 25% of the outstanding principal amount of the Notes,
in accordance with Section 6.02 of the Original Indenture.

     In order to exercise the extension right and elect to pay the Additional Interest as the sole
remedy following the occurrence of any Event of Default relating to the failure to comply with
Section 3.06 in accordance with the preceding paragraph, the Company must notify all Noteholders
and the Trustee and Paying Agent of such election prior to the close of business on the 91st
calendar day after the written notice to the Company of such failure to report (or, if such date is
not a Business Day, on the first Business Day thereafter). Upon the Company’s failure to timely
give such notice, the Notes will be subject to acceleration as provided above.

     For the avoidance of doubt, the provisions of this Section 4.02 will not affect the rights of
Noteholders in the event of the occurrence of any other Event of Default.

     Section 4.03 Waivers of Certain Defaults. Section 6.04 of the Original Indenture is amended,
for purposes of the Notes, to add after numbered clause (2) in the first sentence thereof, the
following “or (3) a continuing Default or Event of Default in the delivery of cash, Common Stock or
other consideration due upon conversion of any Security.”

ARTICLE 5

Optional Redemption of the Notes by the Company

     Section 5.01 Optional Redemption.

     (a) Subject to clause (b) below, on or after June 15, 2015, the Notes shall be redeemable, in
whole or in part, at the option of the Company on any date specified by the Company in accordance
with the Indenture (a “Redemption Date”), at a redemption price equal to 100% of the principal
amount of the Notes to be redeemed plus any accrued and unpaid interest up to, but excluding, the
Redemption Date (the “Redemption Price”); provided that if the Redemption Date is on a date that is
after an Interest Record Date and on or prior to the corresponding Interest Payment Date, the
Redemption Price shall be 100% of the principal amount of the Notes redeemed but shall not include
accrued and unpaid interest, and the Company shall pay such interest on the Interest Payment Date
to the Noteholder of record on the corresponding Interest Record Date. Notwithstanding the
foregoing, the Company may not redeem the Notes on any date if the principal amount of the Notes
has been accelerated, and such acceleration has not been rescinded, on or prior to the relevant
Redemption Date (except in the case of an acceleration resulting from a default by the Company in
the payment of the Redemption Price with respect to such Notes).

     (b) The following provisions of the Original Indenture shall not apply with respect to the
Notes: the last sentence of Section 3.02 of the Original Indenture, clause (8) of Section 3.04 of
the Original Indenture, and the clause “unless the redemption or notice thereof is subject to one
or more conditions as specified in the notice.” Except as otherwise provided herein, redemptions
of the Notes shall be subject to Article III of the Original Indenture.

17

 

     (c) If the Company calls the Notes for redemption, the Notes or portions of the Notes to be
redeemed may be converted by the Noteholder until the close of business on the Business Day
immediately preceding the Redemption Date in accordance with Article 8 hereof.

     Section 5.02 Selection of Notes to Be Redeemed.

     (a) If less than all of the Notes are to be redeemed, unless the procedures of the Depositary
provide otherwise, the Trustee shall select the Notes to be redeemed by lot, on a pro rata basis,
at random or by another method the Trustee considers fair and appropriate (so long as such method
is not prohibited by the rules of any stock exchange or quotation association on which the Notes
are then traded or quoted).

     (b) Notes and portions of Notes that the Trustee selects shall be in principal amounts of
$1,000 or an integral multiple of $1,000. Provisions of this Supplemental Indenture that apply to
Notes called for redemption also apply to portions of Notes called for redemption. The Trustee
shall notify the Company promptly of the Notes or portions of the Notes selected to be redeemed
and, in the case of any Notes selected for partial redemption, the method it has chosen for the
selection of the Note.

     (c) If any Note selected for partial redemption is converted in part before termination of the
conversion right with respect to the portion of the Note so selected, the converted portion of such
Note shall be deemed (so far as may be) to be the portion selected for redemption. Notes that have
been converted during a selection of Notes to be redeemed may be treated by the Trustee as
outstanding for the purpose of such selection.

     Section 5.03 Notice of Redemption. The Company shall notify each Noteholder of the redemption
in the manner provided in Section 3.04 of the Original Indenture. In addition to those matters set
forth in Section 3.04 of the Original Indenture, a notice of redemption sent to the Noteholders
shall state:

     (a) the name of the Paying Agent and Conversion Agent;

     (b) the Base Conversion Rate;

     (c) that the Notes called for redemption may be converted at any time prior to the close of
business on the Business Day immediately preceding the Redemption Date;

     (d) that Noteholders who wish to convert the Notes must comply with the procedures in Section
8.01 and Section 8.02; and

     (e) in the event of the redemption of the Notes in part only, a new Note or Notes for the
unredeemed portion will be issued in the name or names of the Noteholders thereof upon surrender
thereof.

properties and assets to any successor Person in a single transaction or series of related
transactions, unless:

to the Trustee, all of the obligations of the Company under the Notes and the Indenture;

     (b) immediately after giving effect to such transaction, no Default or Event of Default shall

     Any reference in the Original Indenture to Section 5.01 therein shall, for the Notes, be
deemed a reference to this Section 7.01.

20

 

ARTICLE 8

Conversion of Notes

     Section 8.01 Right to Convert. (a) Subject to the provisions of this Article 8, on or prior
to the close of business on the Business Day immediately preceding the Maturity Date, the
Noteholders shall have the right, at such holder’s option, to convert all or any portion (if the
portion to be converted is $1,000 principal amount or an integral multiple thereof) of such
holder’s Note into cash, and, if applicable, Common Stock as provided herein, unless such Notes
have been previously redeemed or repurchased. The obligation of the Company to convert the Notes
is referred to as the “Conversion Obligation.” A Noteholder’s right to convert a Note called for
redemption will terminate at the close of business on the Business Day immediately preceding the
Redemption Date for the Note, unless the Company defaults in making the payment due upon
redemption. In addition, if a Noteholder has exercised its right to require the Company to
repurchase its Notes under Article 9, such Noteholder may not convert its Notes unless it withdraws
its repurchase notice prior to the close of business on the Business Day immediately preceding such
Repurchase Date or Fundamental Change Repurchase Date, as applicable. The delivery to the
Noteholder of the Settlement Amount together with any cash payment for such holder’s fractional
shares, will be deemed to satisfy the Company’s obligation to pay the principal amount of the Notes
and to satisfy the Company’s obligation to pay accrued and unpaid interest through the Conversion
Date, except as provided in Section 8.02(i). Holders of Common Stock issued upon conversion, if
any, will not be entitled to receive any dividends payable to holders of Common Stock as of a
record date before the applicable Conversion Date.

     Subject to the foregoing, prior to January 1, 2038, the Notes are convertible only in the
circumstances described below in clauses (i)-(iv). On or after January 1, 2038, a Noteholder may
surrender Notes for conversion at any time prior to the close of business on the Business Day
immediately preceding the Maturity Date without regard to such conditions.

     (i) Conversion Upon Satisfaction of Common Stock Price Condition. Notes may be
converted during any calendar quarter commencing after June 30, 2008, and only during such
quarter, if the Last Reported Sale Price of the Common Stock for at least 20 Trading Days
during the period of 30 consecutive Trading Days ending on the last Trading Day of the
quarter immediately preceding such quarter (appropriately adjusted to take into account the
occurrence, during such 30 consecutive Trading Days, of any event requiring adjustment of
the Base Conversion Price under this Indenture) is more than 120% of the Base Conversion
Price on such last Trading Day.

     (ii) Conversion Upon Satisfaction of Trading Price Condition. Notes may be converted
during the five consecutive Business Days after any five consecutive Trading Days on which
the Trading Price of $1,000 principal amount of Notes, as determined by the Trustee
following a request by a Noteholder in accordance with the procedures described below in
Section 8.01(c), for each Trading Day of such five Trading Days was less than 97% of the
product of the Last Reported Sale Price of the Common Stock for such Trading Day and the
Applicable Daily Conversion Rate on such day.

21

 

     (iii) Conversion Upon Notice of Redemption. A Note may be converted if such Note has
been called for redemption by the Company pursuant to Section 3.01 and the redemption has
not yet occurred, so long as the Noteholder surrenders such Note for conversion (or if the
Note is held in book-entry form, completes and delivers to the Depositary appropriate
instructions in accordance with the applicable procedures of the Depositary) after the
notice of such redemption is given and prior to the close of business on the Business Day
prior to the applicable Redemption Date (provided that if the Company shall default in
paying the Redemption Price when due, the conversion right shall continue until such time as
such default is cured and such Note is redeemed), whether or not the Note is otherwise
convertible at such time.

     (iv) Conversion Upon Specified Corporate Transactions.

     A Note may be converted during the applicable time period specified below if:

     (A) the Company makes a distribution to all or substantially all holders of
Common Stock of rights, warrants or options entitling them (for a period commencing
no earlier than the date of distribution and expiring not more than 45 calendar days
after the Record Date of the distribution) to subscribe for or purchase shares of
Common Stock at a price per share less than the average Last Reported Sale Prices of
the Common Stock for the 10 Trading Days immediately preceding the date such
distribution was first publicly announced;

     (B) the Company makes a distribution to all or substantially all holders of
Common Stock, of cash or other assets, debt securities, or rights or warrants to
purchase the Company’s securities (other than those described in Section 8.04(a) or
(b)), where the fair market value of such distribution per share of Common Stock (as
determined by the Board of Directors, whose determination shall be conclusive
evidence of such fair market value) exceeds 15% of the average of the Last Reported
Sale Prices of the Common Stock for the ten Trading Days immediately preceding the
date such distribution was first publicly announced;

     (C) the Company is party to a consolidation, merger, share exchange, sale of
all or substantially all of its assets or other similar transaction (in each case
other than with one of the Company’s wholly-owned Subsidiaries), in each case
pursuant to which the Common Stock would be converted into (or holders of Common
Stock would be entitled to receive) cash, securities or other property; or

     (D) a Make-Whole Fundamental Change occurs.

     In the event of a distribution described in Sections 8.01(a)(iv)(A) and (B), the Company shall
cause a written notice of such distribution to be given to the Trustee and the Conversion Agent and
to be mailed to each Noteholder no later than 25 Trading Days prior to the Ex-Dividend Date for
such distribution. Once the Company has given such notice, Noteholders may surrender their Notes
for conversion at any time thereafter until the earlier of the close of business on the Business
Day immediately preceding the Ex-Dividend Date or the Company’s announcement that such distribution
will not take place. If such distribution does not occur as

22

 

anticipated, the Company will issue a press release and notify the holders who have elected to
convert their Notes promptly after the Company determines that such transaction will not occur and
each such holder may elect to withdraw any then pending election to convert by a written notice of
withdrawal delivered to the Conversion Agent within 10 Business Days (or longer period if required
by law) after the Company makes such announcement. In such event, the Noteholders who do not make
such a withdrawal election will receive the applicable Settlement Amount with respect to Notes
surrendered for conversion three Trading Days following the later of (i) the end of the applicable
Cash Settlement Averaging Period or (ii) the expiration of the 10 Business Day (or longer period if
required by law) withdrawal period referred to above. No adjustment to the ability of Noteholders
to convert will be made if the Noteholders are entitled to participate in a distribution without
conversion.

     In the event of a transaction described in Section 8.01(a)(iv)(C), the Company shall cause a
written notice of such transaction to be given to the Trustee and the Conversion Agent and to each
Noteholder no later than the date on which such transaction becomes effective. Once the Company
has given such notice, Noteholders may surrender their Notes for conversion at any time from and
including the Effective Date of such transaction until and including the date that is 30 calendar
days after the Effective Date of such transaction.

     In the event of a Make-Whole Fundamental Change, the Company shall give notice to the Trustee,
the Conversion Agent and the Noteholders in accordance with the provisions of Section 8.03(d).
Once the Company has given such notice, Noteholders may surrender their Notes for conversion at any
time from and including the Effective Date of such transaction (or 15 Trading Days prior to the
date the Company has announced as the anticipated Effective Date of the Make-Whole Fundamental
Change if such event constitutes a Fundamental Change as described under clause (d) of the
definition of Fundamental Change) until and including the Business Day immediately preceding the
Fundamental Change Repurchase Date with respect to such transaction; provided, however, the Company
will have no obligation to deliver any Settlement Amount in respect of any such conversion prior to
the Effective Date of such Make-Whole Fundamental Change.

     In the case of an event constituting a Fundamental Change as described under clause (d) of the
definition of Fundamental Change, if the transaction does not occur, the Company will not be
obligated to increase the Applicable Conversion Rate pursuant to Section 8.03 in connection with
such transaction, regardless of the fact that holders may have elected to convert Notes in
anticipation of the Effective Date of such event and the Company will issue a press release and
notify the holders who have elected to convert their Notes promptly after the Company determines
that such transaction will not occur and each such holder may elect to withdraw any then pending
election to convert by a written notice of withdrawal delivered to the Conversion Agent within 10
Business Days (or longer period if required by law) after the Company makes such announcement. In
such event, the Noteholders who do not make such a withdrawal election will receive the applicable
Settlement Amount with respect to Notes surrendered for conversion three Trading Days following the
later of (i) the end of the applicable Cash Settlement Averaging Period or (ii) the expiration of
the 10 Business Day (or longer period if required by law) withdrawal period referred to above.

23

 

     (b) For each fiscal quarter of the Company commencing prior to January 1, 2038, the Company
shall determine, on the first Business Day following the last Trading Day of the immediately
preceding quarter, whether the Notes are convertible pursuant to clause (i) of Section 8.01(a). If
the conditions set forth in clause (i) of Section 8.01(a) have been met, the Company shall so
notify the Trustee and mail to each Noteholder a written notice. 

     (c) The Trustee shall have no obligation to determine the Trading Price of the Notes pursuant
to clause (ii) of Section 8.01(a) unless the Company has requested such determination in writing;
and the Company shall have no obligation to make such request unless a Noteholder who holds at
least $2,000,000 principal amount of Notes provides the Company with reasonable evidence that the
Trading Price per $1,000 principal amount of Notes is reasonably likely to be less than 97% of the
product of the Last Reported Sale Price of the Common Stock and the Applicable Daily Conversion
Rate then in effect on such date. If a Noteholder provides such evidence or if the Company
otherwise elects to require such determination, the Company shall instruct the Trustee to determine
the Trading Price of the Notes beginning on the next Trading Day and on each successive Trading Day
until the Trading Price of the Notes is greater than or equal to 97% of the product of the Last
Reported Sale price of the Common Stock and the Applicable Daily Conversion Rate on such date. The
Trustee shall promptly notify the Company of its determination on each such day. If the condition
set forth in clause (ii) of Section 8.01(a) has been met, the Company shall so notify the
Noteholders. 

     (d) For purposes of clause (ii) of Section 8.01(a), if the Bid Solicitation Agent cannot
reasonably obtain at least one bid for $5.0 million principal amount of Notes from an independent
nationally recognized securities dealer on a Trading Day, then the Trading Price of Notes will be
deemed to be less than 97% of the product of the Last Reported Sale Price of the Common Stock and
the Applicable Daily Conversion Rate for such Trading Day.

     Section 8.02 Conversion Procedure; Payment Upon Conversion.

     (a) Subject to this Section 8.02, the Company will satisfy the Conversion Obligation with
respect to each $1,000 principal amount of Notes surrendered for conversion in cash and shares of
fully paid Common Stock, if applicable, by delivering a “Settlement Amount” equal to the sum of the
Daily Settlement Amounts for each of the 20 consecutive Trading Days during the applicable Cash
Settlement Averaging Period.

     Except as otherwise provided herein, the Company shall deliver the Settlement Amount to the
Noteholders who have surrendered Notes for conversion on the third Business Day immediately
following the last day of the Cash Settlement Averaging Period in respect of such Notes.

     The (i) Applicable Conversion Rate, (ii) cash component of the Settlement Amount, (iii) number
of full shares of Common Stock, if any, to be delivered, and (iv) cash deliverable in lieu of
fractional shares pursuant to Section 8.02(k), if any, shall be determined by the Company promptly
following the last day of the Cash Settlement Averaging Period. Promptly after such determination,
the Company shall provide written notice to the Trustee and the Conversion Agent of such
determination. The Trustee and the Conversion Agent shall have no responsibility for any such
determination.

24

 

     (b) Before any holder of a Note shall be entitled to convert the same as set forth above, such
holder shall (i) in the case of a Global Note, comply with the procedures of the Depositary in
effect at that time and, if required, pay funds equal to interest payable on the next Interest
Payment Date to which such holder is not entitled as set forth in Section 8.02(i) and, if required,
all transfer or similar taxes, if any, as set forth Section 8.02(f) and (ii) in the case of a Note
issued in certificated form, (1) complete and manually sign and deliver an irrevocable notice to
the Conversion Agent in the form on the reverse of such certificated Note (or a facsimile thereof)
(Exhibit B hereto) (a “Notice of Conversion”) at the office of the Conversion Agent and shall state
in writing therein the principal amount of Notes to be converted and the name or names (with
addresses) in which such holder wishes the certificate or certificates for the shares of Common
Stock to be delivered upon settlement of the Conversion Obligation to be registered, (2) surrender
such Notes, duly endorsed to the Company or in blank, at the office of the Conversion Agent, (3) if
required, pay funds equal to interest payable on the next Interest Payment Date to which such
holder is not entitled as set forth in Section 8.02(i), (4) if required, furnish appropriate
endorsements and transfer documents, and (5) if required, pay all transfer or similar taxes, if
any, as set forth in Section 8.02(f). The Trustee (and if different, the relevant Conversion
Agent) shall notify the Company of any conversion pursuant to this Article 8 on the date of such
conversion. No Notice of Conversion with respect to any Notes may be surrendered by a holder
thereof if such holder has also delivered a Fundamental Change Repurchase Notice or Repurchase
Notice to the Company in respect of such Notes and not validly withdrawn such Fundamental Change
Repurchase Notice or Repurchase Notice, as the case may be, in accordance with Section 9.03.

     If more than one Note shall be surrendered for conversion at one time by the same holder, the
Conversion Obligation with respect to such Notes, if any, that shall be payable upon conversion
shall be computed on the basis of the aggregate principal amount of the Notes (or specified
portions thereof to the extent permitted thereby) so surrendered.

     (c) Upon effectiveness of corporate transactions specified in Section 8.06, the Company will
settle conversion with respect to such transactions as described above (based on the Applicable
Conversion Rate as increased by the Additional Shares as set forth in Section 8.03, as applicable)
on the later to occur of (i) the third Trading Day immediately following the Effective Date of the
transaction and (ii) the third Trading Day following the last day of the applicable Cash Settlement
Averaging Period; provided that, if the Reference Property consists entirely of cash or property
other than publicly traded securities, the Company will deliver the Settlement Amounts to
converting holders no later than the third Business Day after the date of determination of the
value of such consideration, but no earlier than the third Trading Day immediately following the
Effective Date of the transaction.

     (d) A Note shall be deemed to have been converted immediately prior to the close of business
on the date (the “Conversion Date”) that the holder has complied with the requirements set forth in
Section 8.02(b) above. The payment of cash and delivery of shares of Common Stock, if any, and the
payment of cash, if any, in lieu of fractional shares, pursuant to Section 8.02(a) in satisfaction
of the Conversion Obligation shall be made by the Company in no event later than the date specified
in Section 8.02(a) or 8.02(c) or elsewhere in this Supplemental Indenture by (i) payment of the
cash comprising a portion of the Settlement Amount (including amounts of cash in lieu of the
issuance of any fractional shares, if any), and (ii) by issuing or

25

 

causing to be issued, and delivering to the Conversion Agent or to such holder, or such
holder’s nominee or nominees, certificates or a book-entry transfer through the Depositary for the
number of full shares of Common Stock, if any, to which such holder shall be entitled as part of
such Conversion Obligation.

     (e) In case any Note shall be surrendered for partial conversion, the Company shall execute
and the Trustee shall authenticate and deliver to or upon the written order of the holder of the
Note so surrendered, without charge to such holder, a new Note or Notes in authorized denominations
in an aggregate principal amount equal to the unconverted portion of the surrendered Note.

     (f) If a holder submits a Note for conversion, the Company shall pay all documentary, stamp or
similar issue or transfer tax, if any, that may be imposed by the United States or any political
subdivision thereof or taxing authority thereof or therein with respect to the issuance of shares
of Common Stock, upon the conversion. However, the holder shall pay any such tax that is due
because the holder requests any such shares of Common Stock to be issued in a name other than the
holder’s name. The Conversion Agent may refuse to deliver the certificates representing the shares
of Common Stock being issued in a name other than the holder’s name until the Trustee receives a
sum sufficient to pay any tax that will be due because the shares are to be issued in a name other
than the holder’s name. Nothing herein shall preclude any tax withholding required by law or
regulations.

     (g) Except as provided in Section 8.04, no adjustment shall be made for dividends on any
shares issued upon the conversion of any Note with a record date after the Conversion Date.

     (h) Upon the conversion of an interest in a Global Note, the Trustee, or the Custodian at the
direction of the Trustee, shall make a notation on such Global Note as to the reduction in the
principal amount represented thereby. The Company shall notify the Trustee in writing of any
conversion of Notes effected through any Conversion Agent other than the Trustee.

     (i) If Notes are converted after the close of business on a Interest Record Date but prior to
the open of business on the immediately following Interest Payment Date, holders of such Notes as
of the close of business on the Interest Record Date will receive the interest payable on such
Notes on the corresponding Interest Payment Date notwithstanding the conversion. Notes, upon
surrender for conversion during the period from the close of business on any Interest Record Date
but prior to the open of business on the immediately following Interest Payment Date must be
accompanied by funds equal to the amount of the interest payable on the Notes so converted;
provided, however, that no such payment shall be required (1) if the Company has specified a
Redemption Date or Fundamental Change Repurchase Date that is after an Interest Record Date but on
or prior to the Business Day immediately following the related Interest Payment Date, (2) to the
extent of any overdue interest, if any, existing at the time of conversion with respect to such
Note or (3) if the Notes are surrendered for conversion after the close of business on the Interest
Record Date immediately preceding the Maturity Date and before the close of business on the
Business Day immediately preceding the Maturity Date. Except as described above, no payment or
adjustment will be made for accrued and unpaid interest on converted Notes.

26

 

     (j) The Person in whose name the certificate for any shares of Common Stock delivered upon
conversion is registered shall be treated as a stockholder of record as of the close of business on
the applicable Conversion Date; provided, however, if such Conversion Date occurs on any date when
the stock transfer books of the Company shall be closed, such occurrence shall not be effective to
constitute the Person or Persons entitled to receive any such shares of Common Stock due upon
conversion as the record holder or holders of such shares of Common Stock on such date, but such
occurrence shall be effective to constitute the Person or Persons entitled to receive such shares
of Common Stock as the record holder or holders thereof for all purposes at the close of business
on the next succeeding day on which such stock transfer books are open. Upon conversion of Notes,
such Person shall no longer be a Noteholder.

     (k) No fractional shares of Common Stock or securities representing fractional shares of
Common Stock shall be issued upon conversion of any Note or Notes. Instead of any fractional share
of Common Stock or securities representing fractional shares of Common Stock that would otherwise
be issued upon conversion of any Note or Notes (or specified portions thereof), the Company shall
pay a cash adjustment in respect of such fraction (calculated to the nearest one-100th of a share),
as determined by the Company, in an amount equal to the same fraction of the average of the
Applicable Stock Prices on each Trading Day of the applicable Cash Settlement Averaging Period.
For purposes of the foregoing, fractional shares arising from the calculation of the Daily
Settlement Amount for any day in the Cash Settlement Averaging Period shall be aggregated with
fractional shares for all other days in such period in determining the Settlement Amount, and any
whole shares resulting therefrom shall be issued and any remaining fractional shares shall be paid
in cash as provided herein. If more than one Note shall be surrendered for conversion at one time
by the same holder, the number of full shares that shall be issued upon conversion thereof shall be
computed on the basis of the aggregate principal amount of the Notes (or specified portions
thereof) so surrendered.

     (l) When a Noteholder surrenders Notes for conversion, the Company may, at its election,
direct, in writing, the Conversion Agent to surrender such Notes to a financial institution
designated by the Company (the “Designated Institution”) for exchange in lieu of conversion. In
order to accept any Notes surrendered for conversion, the Designated Institution must agree to
deliver, in exchange for such Notes, cash and the number of shares of Common Stock, if any, due
upon conversion based upon the Applicable Conversion Rate in full satisfaction of the Conversion
Obligation, as determined pursuant to Section 8.02(a). If such an election is made, then by the
close of business on the Scheduled Trading Day immediately preceding the start of the Cash
Settlement Averaging Period, the Company will provide written notification to the Noteholder
surrendering the Notes for conversion that it has directed the Designated Institution to make an
exchange in lieu of conversion. If the Designated Institution accepts any such Notes, it will
deliver the cash, and if any, the number of shares of Common Stock due upon conversion to the
Conversion Agent, and the Conversion Agent will deliver such cash and shares of Common Stock to the
converting Noteholder. Any Notes exchanged by the Designated Institution will remain outstanding.
If the Designated Institution does not accept the Notes for exchange or agrees to accept any Notes
for exchange but does not timely deliver the related cash and shares of Common Stock, the Company
will, as promptly as practical thereafter (but in any event, no later than the fourth Trading Day
immediately following the last Trading Day of the relevant Cash Settlement Averaging Period)
convert the Notes as set forth under Section 8.02(a). The Company’s designation of a Designated
Institution to which the Notes may

27

 

be submitted for exchange does not require the Designated Institution to accept any Notes.
The Company will not pay any consideration to, or otherwise enter into any agreement with, the
Designated Institution for or with respect to such designation.

     Section 8.03 Increase of Conversion Rate Upon Conversion Upon Make-Whole Fundamental Changes.
(a) If a Noteholder elects to convert Notes in connection with a Make-Whole Fundamental Change,
then the Applicable Conversion Rate of the Notes being converted by such Noteholder shall be
increased by an additional number of shares of Common Stock (the “Additional Shares”) if any, as
described herein. For purposes of this Section 8.03, any conversion of the Notes by a Noteholder
will be deemed to be “in connection with” such Make-Whole Fundamental Change if it occurs during
the period that begins on the Effective Date of such Make-Whole Fundamental Change (or 15 Trading
Days prior to the date the Company has announced as the anticipated Effective Date of such
Make-Whole Fundamental Change pursuant to clause (d) below if such event constitutes a Fundamental
Change as described under clause (d) of the definition of Fundamental Change) and ends on (and
includes) the Business Day prior to the Fundamental Change Repurchase Date relating to such
Make-Whole Fundamental Change. In the case of a transaction described in clause (d) of the
definition of Fundamental Change, if the transaction does not occur, the Company will not be
obligated to increase the Applicable Conversion Rate in connection with such transaction,
regardless of the fact that holders may have elected to convert Notes in anticipation of the
effective date of such event, and the Company will issue a press release and notify the holders who
have so elected to convert their Notes promptly after the Company determines that the transaction
in question will not occur. Each such holder may then elect to withdraw any election to convert by
a written notice of withdrawal delivered to the Conversion Agent within 10 Business Days after the
Company announces that the transaction will not occur as anticipated (or longer period if required
by applicable law).

The increase in the Applicable Conversion Rate in connection with a Make-Whole Fundamental
Change, expressed as a number of Additional Shares, will be determined by the Company by reference
to the table and adjustments thereto in Section 8.03(b), based on the Effective Date of the
Make-Whole Fundamental Change and the applicable Stock Price. Any such increase in the Applicable
Conversion Rate will be effected by adding to each of the Daily Conversion Rate Fractions
1/20th of the applicable number of Additional Shares set forth in the tables in clause
(b) below with respect to such Make-Whole Fundamental Change.

     (b) The following tables set forth the Effective Date and number of Additional Shares by which
the Applicable Conversion Rate will be increased upon a conversion in connection with a Make-Whole
Fundamental Change that occurs in the corresponding period to be determined by reference to the
Stock Price and Effective Date of the Make-Whole Fundamental Change:

provided, however, that:

     (i) if the actual Stock Price of such Make-Whole Fundamental Change is between two
Stock Prices listed in the tables above under the column titled “Stock Price,” or if the
actual Effective Date of such Make-Whole Fundamental Change is between two Effective Dates
listed in the tables above in the row immediately below the title “Effective Date,” then the
number of Additional Shares for such Make-Whole Fundamental Change shall be determined by
the Company by a straight-line interpolation between the number of Additional Shares set
forth for such higher and lower Stock Prices, or for such earlier and later Effective Dates
based on a 365 day year, as applicable;

29

 

     (ii) if the actual Stock Price of such Make-Whole Fundamental Change is greater than
$170.00 per share (subject to adjustment in the same manner as the Stock Price as provided
in clause (iii) below), or if the actual Stock Price of such Make-Whole Fundamental Change
is less than $46.87per share (subject to adjustment in the same manner as the Stock Price as
provided in clause (iii) below), then the number of Additional Shares shall be equal to zero
and this Section 8.03 shall not require the Company to increase the Applicable Conversion
Rate with respect to such Make-Whole Fundamental Change;

     (iii) if an event occurs that requires, pursuant to Section 8.04, an adjustment to the
Base Conversion Rate, then, on the date and at the time such adjustment is so required to be
made, each price set forth in the tables above under the row titled “Stock Price” shall be
adjusted so that such Stock Price, at and after such time, shall be equal to the product of
(1) such Stock Price as in effect immediately before such adjustment to such Stock Price and
(2) a fraction whose numerator is the Base Conversion Rate in effect immediately before such
adjustment to the Base Conversion Rate and whose denominator is the Base Conversion Rate to
be in effect, in accordance with Section 8.04, immediately after such adjustment to the Base
Conversion Rate; and

     (iv) each number of Additional Shares set forth in the tables above shall be adjusted
in the same manner in which, and for the same events for which, the Base Conversion Rate is
to be adjusted pursuant to Section 8.04.

     In no event will the Applicable Conversion Rate after adjustment described in this Section
8.03(b) exceed 21.3356 per $1,000 principal amount of Notes, subject to adjustments as set forth in
Section 8.04.

     (c) For the avoidance of doubt, the increases provided for in Section 8.03 shall only be made
with respect to the Notes being converted in connection with such Make-Whole Fundamental Change and
shall not be effective as to any Notes not so converted.

     (d) As soon as practicable after the Company determines the anticipated Effective Date of any
proposed Make-Whole Fundamental Change and no later than (i) the 15th Scheduled Trading Day prior
to the date on which such Make-Whole Fundamental Change is anticipated to become effective in the
case of a Make-Whole Fundamental Change described in clause (d) of the definition of Fundamental
Change, or (ii) two Business Days after the Company learns of a Make-Whole Fundamental Change
described in clause (a) of the definition of Fundamental Change, the Company shall provide written
notice of such anticipated Effective Date to the Trustee and the Conversion Agent and mail a notice
to each Noteholder, and shall issue a press release indicating, and publicly announce, through a
public medium that is customary for such announcements, and publish on the Company’s website, the
anticipated Effective Date of such proposed Make-Whole Fundamental Change. Each such notice, press
release notice, announcement and publication shall also state that in connection with such
Make-Whole Fundamental Change, the Company shall increase, in accordance herewith, the Applicable
Conversion Rate applicable to Notes entitled as provided herein to such increase (along with a
description of how such increase shall be calculated and the time periods during which Notes must
be surrendered in order to be entitled to such increase). No later than the actual Effective

30

 

Date of each Make-Whole Fundamental Change, the Company shall provide written notice to the
Trustee and the Conversion Agent and mail a notice to each Noteholder, and shall issue a press
release indicating, and publicly announce, through a public medium that is customary for such
announcements, and publish on the Company’s website, such Effective Date and the amount by which
the Applicable Conversion Rate has been so increased.

     Section 8.04 Adjustment of Base Conversion Rate. The Base Conversion Rate shall be adjusted
from time to time by the Company as follows:

     (a) In case the Company shall issue shares of Common Stock as a dividend or distribution on
shares of Common Stock to all holders of the outstanding shares of Common Stock, or if the Company
effects a share split or share combination, the Base Conversion Rate will be adjusted based on the
following formula:

where,

	 	 	 	 	 
	      CR0 

	 	=
	 	the Base Conversion Rate in effect
immediately prior to the open of
business on the Ex-Dividend Date for
such dividend or distribution, or
immediately prior to the open of
business on the effective date of
such share split or share
combination, as the case may be;
	 
	 	 	 	 
	      CR’

	 	=
	 	the new Base Conversion Rate in
effect immediately after the open of
business on the Ex-Dividend Date for
such dividend or distribution, or
immediately after the open of
business on the effective date of
such share split or share
combination, as the case may be;
	 
	 	 	 	 
	      OS0

	 	=
	 	the number of outstanding shares of
Common Stock immediately prior to the
open of business on the Ex-Dividend
Date for such dividend or
distribution, or immediately prior to
the open of business on the effective
date of such share split or share
combination, as the case may be; and
	 
	 	 	 	 
	      OS’

	 	=
	 	the number of outstanding shares of
Common Stock immediately prior to the
open of business on the Ex-Dividend
Date for such dividend or
distribution, or immediately prior to
the open of business on the effective
date of such share split or share
combination, as the case may be,
assuming, for this purpose only, the
completion of such dividend,
distribution, share split or share
combination, as the case may be,
immediately prior to the open of
business on such date.

Such adjustment shall become effective immediately after the open of business on the Ex-Dividend
Date for such dividend or distribution, or the effective date for such share split or share
combination. If any dividend or distribution of the type described in this Section 8.04(a) is
declared but not so paid or made, or any split or combination of the type described in this Section
8.04(a) is announced but the outstanding shares of Common Stock are not split or

31

 

combined, as the case may be, the new Base Conversion Rate shall be immediately readjusted, effective as of the
date the Board of Directors determines not to pay such dividend or distribution, or split or
combine the outstanding shares of Common Stock, as the case may be, to the Base Conversion Rate
that would then be in effect if such dividend or distribution had not been declared or such share
split or share combination had not been announced.

     (b) In case the Company shall distribute to all or substantially all holders of its Common
Stock any rights or warrants entitling them for a period of not more than 45 calendar days after
the Record Date of such distribution to subscribe for or purchase shares of the Common Stock at a
price per share less than the average of the Last Reported Sale Prices of the Common Stock on the
10 Trading Days immediately preceding the date that such distribution was first publicly announced,
the Base Conversion Rate shall be adjusted based on the following formula:

where,

	 	 	 	 	 
	      CR0

	 	=
	 	the Base Conversion Rate in effect
immediately prior to the open of
business on the Ex-Dividend Date for
such distribution;
	 
	 	 	 	 
	      CR’

	 	=
	 	the new Base Conversion Rate in effect
immediately after the open of business
on the Ex-Dividend Date for such
distribution;
	 
	 	 	 	 
	      OS0

	 	=
	 	the number of outstanding shares of
the Common Stock immediately prior to
the open of business on the
Ex-Dividend Date for such
distribution;
	 
	 	 	 	 
	      X

	 	=
	 	the total number of shares of the
Common Stock issuable pursuant to such
rights or warrants; and
	 
	 	 	 	 
	      Y

	 	=
	 	the number of shares of the Common
Stock equal to the aggregate price
payable to exercise such rights or
warrants, divided by the average of
the Last Reported Sale Prices of
Common Stock over the 10 consecutive
Trading Days ending on the Trading Day
immediately preceding the Ex-Dividend
Date for such distribution of such
rights or warrants.

Such adjustment shall be successively made whenever any such rights or warrants are distributed and
shall become effective immediately after the open of business on the Ex-Dividend Date for such
distribution. To the extent that shares of the Common Stock are not delivered after the expiration
of such rights or warrants, the Base Conversion Rate shall be readjusted to the Base Conversion
Rate that would then be in effect had the adjustments made upon the issuance of such rights or
warrants been made on the basis of delivery of only the number of shares of Common Stock actually
delivered. If such rights or warrants are not so issued, the Base Conversion Rate shall again be
adjusted to be the Base Conversion Rate that would then be in effect if such distribution had not
been declared.

32

 

     In determining whether any rights or warrants entitle the holders to subscribe for or purchase
shares of the Common Stock at less than the applicable Last Reported Sale Price of the Common
Stock, and in determining the aggregate exercise price payable for such Common Stock, there shall
be taken into account any consideration received by the Company for such rights or warrants and any
amount payable upon exercise thereof, with the value of such consideration, if other than cash, to
be determined by the Board of Directors. In no event shall the Base Conversion Rate be decreased
pursuant to this Section 8.04(b), except for readjustments described above.

     (c) In case the Company shall distribute shares of its capital stock, evidences of its
indebtedness or other of its assets or property other than (i) dividends or distributions covered
by Section 8.04(a) or Section 8.04(b), (ii) dividends or distributions paid exclusively in cash,
and (iii) Spin-Offs to which the provisions set forth below in this Section 8.04(c) shall apply
(any of such shares of capital stock, indebtedness, or other asset or property hereinafter in this
Section 8.04(c) called the “Distributed Property”), to all or substantially all holders of its
Common Stock, then, in each such case, the Base Conversion Rate shall be adjusted based on the
following formula:

where,

	 	 	 	 	 
	CR0

	 	=
	 	the Base Conversion Rate in effect
immediately prior to the open of
business on the Ex-Dividend Date for
such distribution;
	 
	 	 	 	 
	CR’

	 	=
	 	the new Base Conversion Rate in effect
immediately after the open of business
on the Ex-Dividend Date for such
distribution;
	 
	 	 	 	 
	SP0

	 	=
	 	the average of the Last Reported Sale
Prices of the Common Stock over the 10
consecutive Trading Days ending on the
Trading Day immediately preceding the
Ex-Dividend Date for such
distribution; and
	 
	 	 	 	 
	FMV

	 	=
	 	the fair market value (as determined
by the Board of Directors) of the
Distributed Property with respect to
one share of the Common Stock on the
Ex-Dividend Date for such
distribution.

Such adjustment shall become effective immediately after the open of business on the Ex-Dividend
Date for such distribution; provided that if “FMV” as set forth above is equal to or greater than
“SP0” as set forth above, in lieu of the foregoing adjustment, adequate provision shall
be made so that each Noteholder shall receive on the date on which the Distributed Property is
distributed to holders of the Common Stock, for each $1,000 principal amount of Notes upon
conversion, the amount of Distributed Property such holder would have received had such holder
owned a number of shares of Common Stock equal to the Applicable Daily Conversion Rate on the
Record Date for such distribution. Except as provided below, if the Board of Directors determines
“FMV” for purposes of this Section 8.04(c) by reference to the actual or when issued trading market
for any securities, it must in doing so consider the prices in such market over the

33

 

same period used in computing the Last Reported Sale Prices of the Common Stock over the 10
consecutive Trading Days ending on the Trading Day immediately preceding the Ex-Dividend Date for
such distribution.

     In lieu of the foregoing, with respect to an adjustment pursuant to this Section 8.04(c) where
there has been a dividend or other distribution on the Common Stock of shares of 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 Base Conversion Rate will be increased based on the
following formula:

where,

	 	 	 	 	 
	CR0

	 	=
	 	the Base Conversion Rate in effect
immediately prior to the open of
business on the Ex-Dividend Date of the
Spin-Off;
	 
	 	 	 	 
	CR’

	 	=
	 	the new Base Conversion Rate in effect
immediately after the open of business
on the Ex-Dividend Date of the Spin-Off;
	 
	 	 	 	 
	FMV

	 	=
	 	the average of the last reported sale
prices of the capital stock or similar
equity interest distributed to holders
of the Common Stock on its principal
trading market applicable to one share
of the Common Stock over the 10
consecutive Trading Days immediately
following, and including, the
Ex-Dividend Date of the Spin-Off (the
“Spin-Off Valuation Period”); and
	 
	 	 	 	 
	MP0

	 	 	 	the average of the Last Reported Sale
Prices of the Common Stock over the
Spin-Off Valuation Period.

The adjustment to the Base Conversion Rate under the preceding paragraph will be deemed to be
effective immediately after the open of business on the Ex-Dividend Date of the Spin-Off; provided
that, for purposes of determining the Base Conversion Rate, in respect of any Trading Day during a
Cash Settlement Averaging Period during a Spin-Off Valuation Period, references in the portion of
this Section 8.04(c) related to Spin-Offs to 10 Trading Days shall be deemed replaced with such
lesser number of Trading Days as have elapsed between the Ex-Dividend Date of such Spin-Off and
such Trading Day.

     If any distribution referred to above is declared but not paid or made, the Base Conversion
Rate shall be readjusted to be the Base Conversion Rate that would then be in effect if such
dividend or distribution had not been declared. For the avoidance of doubt, the adjustment in this
clause (c) does not apply to any distributions to the extent that the right to convert Notes has
been changed into the right to convert into Reference Property in respect of such distribution in
accordance with Section 8.06.

34

 

     (d) If the Company pays any cash dividend to all or substantially all holders of the Common
Stock, the Base Conversion Rate shall be adjusted based on the following formula:

where,

	 	 	 	 	 
	CR0

	 	=
	 	the Base Conversion Rate in effect
immediately prior to the open of
business on the Ex-Dividend Date for
such dividend or distribution;
	 
	 	 	 	 
	CR’

	 	=
	 	the new Base Conversion Rate in effect
immediately after the open of business
on the Ex-Dividend Date for such
dividend or distribution;
	 
	 	 	 	 
	SP0

	 	=
	 	the average of the Last Reported Sale
Prices of the Common Stock over the ten
Trading Days immediately preceding the
Ex-Dividend Date for such dividend or
distribution; and
	 
	 	 	 	 
	C

	 	 	 	the amount of such cash dividend
applicable to one share of Common Stock.

Such adjustment shall become effective immediately after the open of business on the Ex-Dividend
Date for such dividend or distribution; provided that if the portion of the cash so distributed
applicable to one share of the Common Stock is equal to or greater than SP0 as set forth above, in
lieu of the foregoing adjustment, adequate provision shall be made so that each Noteholder shall
have the right to receive on the date on which the relevant cash dividend or distribution is
distributed to holders of Common Stock, for each $1,000 principal amount of Notes upon conversion,
the amount of cash such holder would have received had such holder owned a number of shares equal
to the Applicable Daily Conversion Rate on the Record Date for such distribution. If such dividend
or distribution is not so paid or made, the Base Conversion Rate shall again be adjusted to be the
Base Conversion Rate that would then be in effect if such dividend or distribution had not been
declared.

     For the avoidance of doubt, the adjustment in this clause (d) does not apply to any
distributions to the extent that the right to convert Notes has been changed into the right to
convert into Reference Property in respect of such distribution in accordance with Section 8.06.

     For the avoidance of doubt, for purposes of this Section 8.04(d), in the event of any
reclassification of the Common Stock, as a result of which the Notes become convertible into cash
and one or more classes of Common Stock, if an adjustment to the Base Conversion Rate is thereafter
required pursuant to this Section 8.04(d), references in this Section to one share of Common Stock
or Last Reported Sale Price of one share of Common Stock shall be deemed to refer to a unit or to
the price of a unit consisting of an amount of cash and shares equal to the number of shares of
each class of Common Stock into which the Notes are then convertible plus the cash issued in
respect of one share of Common Stock in such reclassification. The above provisions of this
paragraph shall similarly apply to successive reclassifications.

35

 

     (e) If the Company or any of its Subsidiaries makes a payment in respect of a tender offer or
exchange offer for the Common Stock and the cash and value of any other consideration included in
the payment per share of the Common Stock exceeds the Last Reported Sale 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 Base Conversion Rate shall be increased based on the
following formula:

where,

	 	 	 	 	 
	CR0

	 	=
	 	the Base Conversion Rate in effect
immediately prior to the close of
business on the Trading Day next
succeeding the date such tender or
exchange offer expires;
	 
	 	 	 	 
	CR’

	 	=
	 	the new Base Conversion Rate in effect
immediately after the close of
business on the Trading Day next
succeeding the date such tender or
exchange offer expires;
	 
	 	 	 	 
	AC

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

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

	 	=
	 	the number of outstanding shares of
Common Stock immediately after the
date such tender or exchange offer
expires (after giving effect to the
purchase of all shares accepted for
purchase or exchange pursuant to such
tender offer or exchange offer); and
	 
	 	 	 	 
	SP’

	 	=
	 	the average of the Last Reported Sale
Prices of Common Stock over the 10
consecutive Trading Days commencing
on, and including, the Trading Day
next succeeding the date such tender
or exchange offer expires,

such adjustment to become effective immediately after the close of business on the Trading Day
immediately following the date such tender or exchange offer expires; provided that, for purposes
of determining the Base Conversion Rate, in respect of any Trading Day during a Cash Settlement
Averaging Period during the 10 Trading Days immediately following, but excluding, the date that any
such tender or exchange offer expires, references in this Section 8.04(e) to 10 Trading Days shall
be deemed replaced with such lesser number of Trading Days as have elapsed between the date that
such tender or exchange offer expires and such Trading Date. If the Company or one of its
Subsidiaries is obligated to purchase shares of Common Stock pursuant to any such tender or
exchange offer but is permanently prevented by applicable law from effecting any or all or any
portion of such purchases or all such purchases are rescinded, the new Base Conversion Rate shall
be readjusted to be the Base Conversion Rate that would then be

36

 

in effect if such tender or exchange offer had not been made or had been made only in respect of
the purchases that had been effected. In no event shall the Base Conversion Rate be decreased
pursuant to this Section 8.04(e), except with respect to readjustment described above.

     (f) For purposes of this Section 8.04, the term “Record Date” shall mean, with respect to any
dividend, distribution or other transaction or event in which the holders of Common Stock (or other
security) have the right to receive any cash, securities or other property or in which the Common
Stock (or other applicable security) is exchanged for or converted into any combination of cash,
securities or other property, the date fixed for determination of stockholders entitled to receive
such cash, securities or other property (whether such date is fixed by the Board of Directors or by
statute, contract or otherwise).

     (g) Except as stated herein, the Company shall not adjust the Base Conversion Rate for the
issuance of shares of its Common Stock or any securities convertible into or exchangeable for
shares of its Common Stock or the right to purchase shares of its Common Stock or such convertible
or exchangeable securities.

     (h) In addition to those required by clauses Section 8.04(a), (b), (c), (d) and (e) of this
Section 8.04, and to the extent permitted by applicable law and subject to the applicable rules of
the National Securities Exchange, the Company from time to time may increase the Base Conversion
Rate by any amount for a period of at least 20 Business Days. In addition, the Company may also
(but is not required to) increase the Base Conversion Rate to avoid or diminish any income tax to
holders of Common Stock or rights to purchase Common Stock in connection with any dividend or
distribution of shares (or rights to acquire shares) or similar event. Whenever the Base
Conversion Rate is increased pursuant to the preceding sentence, the Company shall mail to the
holder of each Note at its last address appearing on the Note Register provided for in Section 2.05
a notice of the increase at least 15 calendar days prior to the date the increased Base Conversion
Rate takes effect, and such notice shall state the increased Base Conversion Rate and the period
during which it will be in effect.

     (i) The Base Conversion Rate will not be adjusted:

     (i) upon the issuance of any shares of the Common Stock pursuant to any present or
future plan providing for the reinvestment of dividends or interest payable on the Company’s
securities and the investment of additional optional amounts in shares of the Common Stock
under any plan;

     (ii) upon the issuance of any shares of the Common Stock or restricted stock units or
options or rights (including stockholder appreciation rights) to purchase those shares
pursuant to any present or future employee, director or consultant benefit plan or program
of or assumed by the Company or any of the Company’s Subsidiaries;

     (iii) upon the issuance of any shares of the Common Stock pursuant to any option,
warrant, right or exercisable, exchangeable or convertible security not described in clause
(ii) of this subsection and outstanding as of the date the Notes were first issued;

37

 

     (iv) upon the repurchase of any of the Common Stock pursuant to an open-market share
repurchase program or other buy-back transaction that is not a tender offer or exchange
offer of the nature described in this Section 8.04;

     (v) for a change in the par value of the Common Stock;

     (vi) for accrued and unpaid interest; or

     (vii) for any transactions described in this Section 8.04, if Noteholders participate
(as a result of holding the Notes, and at the same time as holders of Common Stock
participate) in such transactions as if such Noteholders held a number of shares of Common
Stock equal to the Applicable Daily Conversion Rate at the time such adjustment would be
required, multiplied by the principal amount (expressed in thousands) of Notes held by such
Noteholder, without having to convert their Notes.

     (j) All calculations and other determinations under this Article 8 shall be made by the
Company and shall be made to the nearest one-ten thousandth (1/10,000th) of a share.
Notwithstanding anything in this Section 8.04, the Company will not be required to adjust the Base
Conversion Rate unless the adjustment would result in a change of at least 1% of the Base
Conversion Rate. However, the Company will carry forward any adjustments that are less than 1% of
the Base Conversion Rate and take them into account when determining subsequent adjustments. In
addition, the Company will make any carry forward adjustments not otherwise effected (i) upon
conversion of the Notes, (ii) in connection with a call for redemption of Notes and (iii) 25
Scheduled Trading Days prior to the Maturity Date of the Notes. No adjustment to the Base
Conversion Rate will be made if it results in a Base Conversion Price that is less than the par
value (if any) of Common Stock.

     (k) At any time the Base Conversion Rate is adjusted as described in this Section 8.04, the
Incremental Share Factor and Daily Share Cap will be adjusted in the same proportion.

     (l) Whenever the Base Conversion Rate, Incremental Share Factor and Daily Share Cap are
adjusted as herein provided, the Company shall promptly file with the Trustee and any Conversion
Agent other than the Trustee an Officers’ Certificate setting forth the Base Conversion Rate,
Incremental Share Factor and Daily Share Cap after such adjustment and setting forth a brief
statement of the facts requiring such adjustment. Unless and until a responsible officer of the
Trustee shall have received such Officers’ Certificate, the Trustee and Conversion Agent shall not
be deemed to have knowledge of any adjustment of the Base Conversion Rate, Incremental Share Factor
or Daily Share Cap and may assume without inquiry that the last, Base Conversion Rate, Incremental
Share Factor and Daily Share Cap 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 Base
Conversion Rate, Incremental Share Factor and Daily Share Cap setting forth the adjusted Base
Conversion Rate, Incremental Share Factor and Daily Share Cap and the date on which each adjustment
becomes effective and shall mail such notice of such adjustment of the Base Conversion Rate,
Incremental Share Factor and Daily Share Cap to the holder of each Note at its last address
appearing on the Note Register provided

38

 

for in Section 2.05, within 10 calendar days of the
effective date of such adjustment. Failure to deliver such notice shall not affect the legality or
validity of any such adjustment.

     (m) For purposes of this Section 8.04, 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.

     (n) The Board of Directors will make appropriate adjustments, in its good faith determination,
to account for any adjustment to the Base Conversion Rate that becomes effective, or any event
requiring an adjustment to the Base Conversion Rate where the Ex-Dividend Date of the event occurs,
during any consecutive Trading Day period used for the measurement of any adjustment required under
this Section 8.04. In addition, if the effective date of any adjustment event described in this
8.04 occurs during a Cash Settlement Averaging Period for any Notes, then the Company will make
proportional adjustments to the number of deliverable shares for each Trading Day during the
portion of the Cash Settlement Averaging Period preceding the effective date of such adjustment
event.

     Section 8.05 Shares to Be Fully Paid. The Company shall provide, free from preemptive rights,
out of its authorized but unissued shares or shares held in treasury, sufficient shares of Common
Stock to provide for conversion of the Notes from time to time as such Notes are presented for
conversion.

     Section 8.06 Effect of Reclassification, Consolidation, Merger or Sale; Treatment of Reference
Property.

     (a) Upon the occurrence of (i) any reclassification of the Common Stock (other than a change
only in par value, or from par value to no par value, or from no par value to par value, or a
change as a result of a subdivision or combination of Common Stock), (ii) any consolidation, merger
or combination involving the Company, or (iii) any sale or conveyance to another Person of all or
substantially all of the property and assets of the Company, and pursuant to such reclassification,
consolidation, merger, combination, sale or conveyance, the Common Stock is converted into or
exchanged for stock, other securities, other property or assets (including cash) or any combination
thereof (any such event a “Merger Event”), then the Company, or such successor or surviving,
purchasing or transferee Person, as the case may be, shall, as a condition precedent to such Merger
Event, execute and deliver to the Trustee a supplemental indenture providing that, at the effective
time of the Merger Event, the right to receive shares of Common Stock upon conversion of a Note
with respect to the portion of the Daily Conversion Value in excess of $50, if any, will be changed
into the right to receive the kind and amount of shares of stock, other securities or other
property or assets (including cash) or any combination thereof (in the same proportions) that a
holder would have been entitled to receive (the “Reference Property”) in such transaction in
respect of such Common Stock, and from and after the effective time of such transaction, the Daily
Conversion Values and Daily Share Amounts will be determined based on the values and amounts, as
applicable, of one unit of Reference Property (a “unit” of Reference Property being the kind and
amount thereof (in the same proportions) of Reference Property that a holder of one share of Common
Stock would receive in such

39

 

transaction) and the Daily Conversion Rate Fractions will relate to
such units of Reference Property.

     In the event the Company shall execute a supplemental indenture pursuant to this Section 8.06,
the Company shall promptly give the Trustee an Officers’ Certificate briefly stating the reasons
therefore, the kind or amount of cash, securities or property or asset that will comprise the
Reference Property after any such Merger Event, any adjustment to be made with respect thereto and
that all conditions precedent have been complied with, and shall promptly mail notice thereof to
all Noteholders. The Company shall cause notice of the execution of such supplemental indenture to
be mailed to each Noteholder, at its address appearing on the Note Register provided for in this
First Supplemental Indenture, within 20 calendar days after execution thereof. Failure to deliver
such notice shall not affect the legality or validity of such supplemental indenture.

     (b) If the Merger Event causes the Common Stock to be converted into the right to receive more
than a single type of consideration (determined based in part upon any form of stockholder
election), the Reference Property into which the Notes will be convertible will be deemed to be the
weighted average of the types and amounts of such consideration received by the holders of Common
Stock that affirmatively make such an election.

     (c) None of the foregoing provisions shall affect the right of a Noteholder to convert its
Notes in accordance with the provisions of this Article 8 prior to the effective date of such
Merger Event. The provisions of this Section 8.06 shall similarly apply to successive Merger
Events.

     Section 8.07 Certain Covenants.

     (a) The Company covenants that all shares of Common Stock issued upon conversion of Notes will
be fully paid and non-assessable by the Company and free from all taxes, liens and charges with
respect to the issue thereof.

     (b) The Company covenants that, if any shares of Common Stock to be provided for the purpose
of conversion of Notes hereunder require registration with or approval of any governmental
authority under any federal or state law before such shares may be validly issued upon conversion,
the Company shall, to the extent then permitted by the rules and interpretations of the Commission,
secure such registration or approval, as the case may be.

     (c) The Company further covenants that if at any time the Common Stock shall be listed on any
National Securities Exchange or automated quotation system the Company shall, if permitted and
required by the rules of the relevant exchange or automated quotation system, list and keep listed,
so long as the Common Stock shall be so listed on such exchange or automated quotation system, any
Common Stock issuable upon conversion of the Notes.

     Section 8.08 Responsibility of Trustee. The Trustee and any other Conversion Agent shall not
at any time be under any duty or responsibility to any Noteholder to determine the Applicable
Conversion Rate (or any adjustment thereto) or whether any facts exist that may require any
adjustment (including any increase) of the Base Conversion Rate, or with respect to the nature or
extent or calculation of any such adjustment when made, or with respect to the

40

 

method employed, or
herein or in any supplemental indenture provided to be employed, in making the same. The Trustee
and any other Conversion Agent shall not be accountable with
respect to the validity or value (or the kind or amount) of any shares of Common Stock, or of
any securities, property or cash that may at any time be issued or delivered upon the conversion of
any Note; and the Trustee and any other Conversion Agent make no representations with respect
thereto. Neither the Trustee nor any Conversion Agent shall be responsible for any failure of the
Company to issue, transfer or deliver any shares of Common Stock or stock certificates or other
securities or property or cash upon the surrender of any Note for the purpose of conversion or to
comply with any of the duties, responsibilities or covenants of the Company contained in this
Article. Without limiting the generality of the foregoing, neither the Trustee nor any Conversion
Agent shall be under any responsibility to determine the correctness of any provisions contained in
any supplemental indenture entered into pursuant to Section 8.06 relating either to the kind or
amount of shares of stock or securities or property (including cash) receivable by Noteholders upon
the conversion of their Notes after any event referred to in such Section 8.06 or to any adjustment
to be made with respect thereto, but, subject to the provisions of Section 7.01 of the Original
Indenture, may accept (without any independent investigation) as conclusive evidence of the
correctness of any such provisions, and shall be protected in relying upon, the Officers’
Certificate (which the Company shall be obligated to file with the Trustee prior to the execution
of any such supplemental indenture) with respect thereto.

     Section 8.09 Notice to Holders Prior to Certain Actions. In case:

     (a) the Company shall declare a dividend (or any other distribution) on its Common Stock that
would require an adjustment in the Base Conversion Rate pursuant to Section 8.04; or

     (b) the Company shall authorize the granting to all of the holders of its Common Stock of
rights or warrants to subscribe for or purchase any share of any class or any other rights or
warrants that would require an adjustment in the Base Conversion Rate pursuant to Section 8.04; or

     (c) of any reclassification of the Common Stock (other than a subdivision or combination of
its outstanding Common Stock, or a change in par value, or from par value to no par value, or from
no par value to par value), or of any consolidation or merger to which the Company is a party and
for which approval of any stockholders of the Company is required, or of the sale or transfer of
all or substantially all of the assets of the Company; or

     (d) of the voluntary or involuntary dissolution, liquidation or winding-up of the Company;

the Company shall give to the Trustee and to mail to each Noteholder at its address appearing on
the Note Register or publicly announce, unless another notice of such event is specified elsewhere
in this Supplemental Indenture, at least 15 calendar days prior to the applicable date hereinafter
specified, a notice stating (i) the date on which a record is to be taken for the purpose of such
dividend, distribution or rights or warrants, or, if a record is not to be taken, the date as of
which the holders of Common Stock of record to be entitled to such dividend, distribution or rights
are to be determined, or (ii) the date on which such reclassification, consolidation, merger, sale,
transfer, dissolution, liquidation or winding-up is expected to become effective or occur,

41

 

 and the
date as of which it is expected that holders of Common Stock of record shall be entitled to
exchange their Common Stock for securities or other property deliverable upon such
reclassification, consolidation, merger, sale, transfer, dissolution, liquidation or winding-up.
Failure to give such notice, or any defect therein, shall not affect the legality or validity of
such dividend, distribution, reclassification, consolidation, merger, sale, transfer, dissolution,
liquidation or winding-up.

     Section 8.10 Stockholder Rights Plans.

     (a) The Company has adopted a stockholder rights plan, pursuant to which certain rights (the
“Rights”) are distributed to the holders of Common Stock. The Company’s stockholder rights plan
provides that each share of Common Stock issued (including upon conversion of the Notes) at any
time prior to the distribution of separate certificates representing such Rights will be entitled
to receive such Rights. There shall not be any adjustment to the conversion privilege, the Base
Conversion Rate, Incremental Share Factor or Daily Share Cap at any time based on the Company’s
stockholder rights plan, any amendment to that plan, or any further stockholder rights plan as
contemplated by Section 8.10(b) below that the Company may adopt prior to the distribution of
separate certificates representing such Rights. If, however, prior to any conversion, the Rights
have separated from the Common Stock, the Base Conversion Rate, Incremental Share Factor and Daily
Share Cap shall be adjusted at the time of separation as if the Company distributed to all holders
of Common Stock, shares of capital stock, evidences of indebtedness, the Company’s assets, debt
securities or rights as described in Section 8.04(c), subject to readjustment in the event of the
expiration, termination or redemption of such Rights; provided, however, no person (including a
participant in a group within the meaning of Section 13(d)(3) of the Exchange Act) whose actions or
ownership caused the separation of the Rights from the Common Stock shall be entitled to such
adjustments.

     (b) In the event that the Company distributes rights or warrants pursuant to any amendment to
the Company’s existing stockholder rights plan, or any further stockholder rights plan to all
holders of its Common Stock entitling the holders thereof to subscribe for or purchase shares of
the Company’s capital stock, including Common Stock (either initially or under certain
circumstances), which rights or warrants, until the occurrence of a specified event or events
(“Trigger Event”): (i) are deemed to be transferred with such shares of the Common Stock; (ii) are
not exercisable; and (iii) are also issued in respect of future issuances of the Common Stock, then
such rights or warrants shall be deemed not to have been distributed for purposes of Section
8.04(c) (and no adjustment to the Base Conversion Rate under Section 8.04(c) will be required)
until the occurrence of the earliest Trigger Event, whereupon such rights and warrants shall be
deemed to have been distributed and an appropriate adjustment (if any is required) to the Base
Conversion Rate shall be made under Section 8.04(c) (subject to the proviso in Section 8.10(a)).
In addition, in the event of any distribution (or deemed distribution) of rights or warrants, or
any Trigger Event or other event (of the type described in the preceding sentence) with respect
thereto that was counted for purposes of calculating a distribution amount for which an adjustment
to the Base Conversion Rate under Section 8.04(c) was made, (1) in the case of any such rights or
warrants that shall all have been redeemed or repurchased without exercise by any holders thereof,
the Base Conversion Rate shall be readjusted upon such final redemption or repurchase to give
effect to such distribution or Trigger Event, as the case may be, as though it were a cash
distribution, equal to the per share redemption or repurchase price received by a

42

 

holder or holders
of Common Stock with respect to such rights or warrants (assuming such holder had retained such
rights or warrants), made to all holders of Common Stock as of the date
of such redemption or repurchase, and (2) in the case of such rights or warrants that shall
have expired or been terminated without exercise by any holders thereof, the Base Conversion Rate
shall be readjusted as if such rights and warrants had not been issued (subject to the proviso in
Section 8.10(a)).

ARTICLE 9

Repurchase of Notes at Option of Holders

     Section 9.01 Repurchase at Option of Holders.

     (a) Notes or portions thereof shall be repurchased by the Company at the option of the holder
for cash on each of June 15, 2015, June 15, 2020, June 15, 2025, June 15, 2030 and June 15, 2035
(each, a “Repurchase Date”), at a purchase price (the “Repurchase Price”) equal to 100% of the
principal amount of the Notes to be repurchased, plus accrued and unpaid interest thereon to, but
excluding, such Repurchase Date. The Company will pay interest due on any such the Repurchase Date
to the Noteholder of record on the relevant Interest Record Date, which may or may not be the same
Person to whom the Company will pay the Repurchase Price, and the Repurchase Price will not include
such interest so paid.

     (b) At least 20 Business Days prior to any Repurchase Date, the Company will send a notice
(the “Company Notice”) by electronic transmission or by first class mail to the Trustee and to each
holder (and to beneficial owners as required by applicable law). The notice shall include the form
of Repurchase Notice to be completed by a holder and shall state:

     (i) the Repurchase Date;

     (ii) the Repurchase Price and the Base Conversion Rate;

     (iii) the name and address of the Trustee, (or other Paying Agent appointed by the
Company) and the Conversion Agent;

     (iv) that Notes as to which a Repurchase Notice has been given may be converted only in
accordance with Article 8 and the terms of the Notes if the applicable Repurchase Notice has
been withdrawn in accordance with the terms of this Article 9;

     (v) that Notes must be surrendered to the Paying Agent to collect payment;

     (vi) that the Repurchase Price for any Note as to which a Repurchase Notice has been
given and not withdrawn will be paid promptly following the later of the Repurchase Date and
the time of surrender of such Note as described in clause (v) above;

     (vii) whether or not the Notes are convertible prior to the repurchase and a summary of
the procedures for such conversion;

     (viii) the procedures the holder must follow to exercise its repurchase rights under
this Section 9.01;

43

 

     (ix) the procedures for withdrawing a Repurchase Notice; and

     (x) the CUSIP number of the Notes.

     (c) Purchases of Notes under this Section 9.01 shall be made, at the option of the holder
thereof, upon:

     (i) delivery to the Paying Agent by the holder of a written notice of repurchase
substantially in the form set forth on the reverse of the Note as Exhibit E thereto (a
“Repurchase Notice”) during the period beginning at any time from the open of business on
the date that is 20 Business Days prior to the relevant Repurchase Date until the close of
business on the Business Day immediately preceding the Repurchase Date stating:

     (A) if certificated Notes have been issued, the certificate number of the Notes
that the holder will deliver to be purchased;

     (B) the portion of the principal amount of the Notes to be purchased, which
portion must be in principal amounts of $1,000 or an integral multiple of $1,000;
and

     (C) that such Notes shall be purchased by the Company as of the Repurchase Date
pursuant to the terms and conditions specified in the Notes and in this Supplemental
Indenture;

provided, however, that if the Notes are not in certificated form, the Repurchase Notice
must comply with appropriate Depositary procedures; and

     (ii) book-entry transfer of such Notes (or delivery of such certificated Notes) to the
Paying Agent at any time after delivery of the Repurchase Notice (together with all
necessary endorsements) at the corporate trust office of the Paying Agent in the United
States, such book-entry transfer or delivery being a condition to receipt by the holder of
the Repurchase Price therefor; provided, however, that such Repurchase Price shall be so
paid pursuant to this Section 9.01 only if the Note so delivered to the Paying Agent shall
conform in all respects to the description thereof in the related Repurchase Notice.

     (d) No Repurchase Notice with respect to any Notes may be surrendered by a holder thereof if
such holder has also tendered a Fundamental Change Repurchase Notice and not validly withdrawn such
Fundamental Change Repurchase Notice in accordance with Section 9.02.

     (e) The Company may purchase from the holder thereof, pursuant to this Section 9.01, a portion
of a Note, if the principal amount of such portion is $1,000 or an integral multiple of $1,000.
Provisions of this Supplemental Indenture that apply to the purchase of all of a Note also apply to
the purchase of such portion of such Note.

     (f) Any repurchase by the Company contemplated pursuant to the provisions of this Section 9.01
shall be consummated by the payment of the Repurchase Price promptly following

44

 

the later of the
Business Day following the Repurchase Date and the time of the book-entry transfer or delivery of
the Note as described in Section 9.04(a).

     (g) Notwithstanding anything herein to the contrary, any holder delivering to the Paying Agent
the Repurchase Notice contemplated by this Section 9.01 shall have the right to withdraw, in whole
or in part, such Repurchase Notice at any time prior to the close of business on the Business Day
immediately preceding the Repurchase Date by delivery of a written notice of withdrawal to the
Paying Agent in accordance with Section 9.03 below.

     (h) The Paying Agent shall promptly notify the Company of the receipt by it of any Repurchase
Notice or written notice of withdrawal thereof.

     (i) Notwithstanding the foregoing, no Notes may be repurchased by the Company at the option of
the holders if the principal amount of the Notes has been accelerated, and such acceleration has
not been rescinded, on or prior to the Repurchase Date (except in the case of an acceleration
resulting from a default by the Company in the payment of the Repurchase Price with respect to such
Notes).

     (j) In connection with any repurchase, the Company will:

     (i) comply with the provisions of Rule 13e-4, Rule 14e-1 and any other applicable
tender offer rules under the Exchange Act;

     (ii) file a Schedule TO or any successor or similar schedule, if required under the
Exchange Act; and

     (iii) otherwise comply with all applicable U.S. federal and state securities laws in
connection with any offer by the Company to purchase the Notes.

     Section 9.02 Repurchase at Option of Holders upon a Fundamental Change.

     (a) In the event a Fundamental Change shall occur at any time when any Notes remain
outstanding, each Noteholder shall have the right, at such holder’s option, to require the Company
to purchase all of such holders’ Notes or any portion of the principal amount thereof that is equal
to $1,000 or an integral multiple thereof on a date specified by the Company (the “Fundamental
Change Repurchase Date”) that is not less than 20 nor more than 35 Business Days (or any longer
period required by law) after the date on which the Company gives the notice of such Fundamental
Change pursuant to clause (b) below, at a purchase price in cash equal to 100% of the principal
amount thereof, together with accrued and unpaid interest thereon to, but excluding, the
Fundamental Change Repurchase Date (the “Fundamental Change Repurchase Price”). If such
Fundamental Change Repurchase Date falls after a Interest Record Date and on or prior to the
corresponding Interest Payment Date, the Company shall instead pay the principal amount to the
Noteholders surrendering the Notes for repurchase pursuant to this Section 9.02, and pay the full
amount of accrued and unpaid interest payable on such Interest Payment Date to the holder of record
on the close of business on the corresponding Interest Record Date. Repurchases of Notes under
this Section 9.02 shall be made on the Fundamental Change Repurchase Date, at the option of the
holder thereof, upon:

45

 

     (i) delivery to the Paying Agent by a holder of a duly completed notice in the form set
forth on the reverse of the Note as Exhibit C thereto (the “Fundamental
Change Repurchase Notice”) on or prior to the close of business on the Business Day
immediately preceding the Fundamental Change Repurchase Date; and

     (ii) delivery or book-entry transfer of the Notes to the Paying Agent at any time after
delivery of the Fundamental Change Repurchase Notice (together with all necessary
endorsements) at the corporate trust office of the Paying Agent in the United States, such
book-entry transfer or delivery being a condition to receipt by the holder of the
Fundamental Change Repurchase Price therefor; provided that such Fundamental Change
Repurchase Price shall be so paid pursuant to this Section 9.02 only if the Note so
delivered to the Paying Agent shall conform in all respects to the description thereof in
the related Fundamental Change Repurchase Notice.

     The Fundamental Change Repurchase Notice shall state:

     (A) if certificated, the certificate numbers of Notes to be delivered for
repurchase;

     (B) the portion of the principal amount of Notes to be repurchased, which must
be $1,000 or an integral multiple thereof; and

     (C) that the Notes are to be repurchased by the Company pursuant to the
applicable provisions of the Notes and this Supplemental Indenture;

provided, however, that if the Notes are not in certificated form, the Fundamental Change
Repurchase Notice must comply with appropriate Depositary procedures.

     Any repurchase by the Company contemplated pursuant to the provisions of this Section 9.02
shall be consummated by the payment of the Fundamental Change Repurchase Price promptly following
the later of the Business Day following the Fundamental Change Repurchase Date and the time of the
book-entry transfer or delivery of the Note as described in Section 9.04(a).

     Notwithstanding anything herein to the contrary, any holder delivering to the Paying Agent the
Fundamental Change Repurchase Notice contemplated by this Section 9.02 shall have the right to
withdraw, in whole or in part, such Fundamental Change Repurchase Notice at any time prior to the
close of business on the Business Day immediately preceding the Fundamental Change Repurchase Date
by delivery of a written notice of withdrawal to the Paying Agent in accordance with Section 9.03
below.

     The Paying Agent shall promptly notify the Company of the receipt by it of any Fundamental
Change Repurchase Notice or written notice of withdrawal thereof.

     (b) Within 15 Business Days after the occurrence of a Fundamental Change, the Company shall
give to the Trustee, the Paying Agent and the Conversion Agent and provide or cause to be provided
to all holders of record of the Notes a written notice (the “Fundamental Change Company Notice”) of
the occurrence of the Effective Date of the Fundamental Change

46

 

and of the repurchase right at the
option of the holders arising as a result thereof. Simultaneously with the providing of such
notice, the Company will also publish a notice containing the
information set forth in the Fundamental Change Company Notice in a newspaper of general
circulation in The City of New York or publish such information on the Company’s website or through
such other public medium as the Company may use at that time.

     Each Fundamental Change Company Notice shall specify:

     (i) the events causing the Fundamental Change;

     (ii) the effective date of the Fundamental Change;

     (iii) the last date on which a holder may exercise the repurchase right set forth in
this Section 9.02;

     (iv) the Fundamental Change Repurchase Price;

     (v) the Fundamental Change Repurchase Date;

     (vi) the name and address of the Paying Agent and the Conversion Agent, if applicable;

     (vii) the Base Conversion Rate, and if applicable, any adjustments to the Applicable
Conversion Rate;

     (viii) if applicable, that the Notes with respect to which a Fundamental Change
Repurchase Notice has been delivered by a holder may be converted only if the holder
withdraws the Fundamental Change Repurchase Notice in accordance with the terms of the
Indenture;

     (ix) that the holder must exercise the repurchase right set forth in this Section 9.02
on or prior to the close of business on the Business Day immediately preceding the
Fundamental Change Repurchase Date (the “Fundamental Change Expiration Time”);

     (x) that the holder shall have the right to withdraw any Notes surrendered prior to the
Fundamental Change Expiration Time; and

     (xi) the procedures that holders must follow to require the Company to repurchase their
Notes.

     No failure of the Company to give the foregoing notices and no defect therein shall limit the
Noteholders’ repurchase rights or affect the validity of the proceedings for the repurchase of the
Notes pursuant to this Section 9.02.

     (c) Notwithstanding the foregoing, no Notes may be repurchased by the Company at the option of
the holders upon a Fundamental Change if the principal amount of the Notes has been accelerated,
and such acceleration has not been rescinded, on or prior to the Fundamental

47

 

Change Repurchase Date (except in the case of an acceleration resulting from a default by the
Company in the payment of the Fundamental Change Repurchase Price with respect to such Notes).

     (d) In connection with any purchase offer, the Company will, to the extent applicable:

          (i) comply with the provisions of Rule 13e-4, Rule 14e-1 and any other applicable
tender offer rules under the Exchange Act;

          (ii) file a Schedule TO or any successor or similar schedule, if required under the
Exchange Act; and

          (iii) otherwise comply with all applicable U.S. federal and state securities laws in
connection with any offer by the Company to purchase the Notes.

     Section 9.03 Withdrawal of Repurchase Notice or Fundamental Change Repurchase Notice.

     (a) A Repurchase Notice or Fundamental Change Repurchase Notice may be withdrawn by means of a
written notice of withdrawal delivered to the corporate trust office of the Paying Agent in
accordance with the Repurchase Notice or Fundamental Change Repurchase Notice, as the case may be,
at any time prior to the close of business on the Business Day immediately preceding the Repurchase
Date or the Fundamental Change Repurchase Date, as the case may be, specifying:

          (i) the certificate number, if any, of the Note in respect of which such notice of
withdrawal is being submitted, or the appropriate Depositary information if the Note in
respect of which such notice of withdrawal is being submitted is represented by a Global
Note;

          (ii) the principal amount of the Note with respect to which such notice of withdrawal
is being submitted; and

          (iii) the principal amount, if any, of such Note that remains subject to the original
Repurchase Notice or Fundamental Change Repurchase Notice, as the case may be, which portion
must be in principal amounts of $1,000 or an integral multiple of $1,000;

provided, however, that if the Notes are not in certificated form, the notice must comply with
appropriate procedures of the Depositary.

     Section 9.04 Deposit of Repurchase Price or Fundamental Change Repurchase Price.
(a) The Company will deposit with the Trustee (or other Paying Agent appointed by the Company, or if the
Company is acting as its own Paying Agent, set aside, segregate and hold in trust as provided in
Section 4.04 of the Original Indenture) on or prior to 11:00 a.m., New York City time, on the
Business Day following the Repurchase Date or Fundamental Change Repurchase Date, as the case may
be, an amount of money sufficient to repurchase all of the Notes to be repurchased at the
appropriate Repurchase Price or Fundamental Change Repurchase

Price, as the case may be. Subject to receipt of funds and/or Notes by the Trustee (or other
Paying Agent appointed by the Company), payment for Notes surrendered for repurchase (and not
withdrawn prior to the Repurchase Date or Fundamental Change Expiration Time, as applicable) will
be made on the later of (i) the Business Day following the Repurchase Date or the Fundamental
Change Repurchase Date, as the case may be, with respect to such Note (provided the holder has
satisfied the conditions in Section 9.01 or Section 9.02, as applicable) and (ii) the time of
book-entry transfer or the delivery of such Note to the Trustee (or other Paying Agent appointed by
the Company) by the holder thereof in the manner required by Section 9.01 or Section 9.02, as
applicable, by mailing checks for the amount payable to the holders of such Notes entitled thereto
as they shall appear in the Note Register; provided, however, that payments to the Depositary shall
be made by wire transfer of immediately available funds to the account of the Depositary or its
nominee. The Trustee shall, promptly after such payment and upon written demand by the Company,
return to the Company any funds in excess of the Repurchase Price or Fundamental Change Repurchase
Price, as the case may be.

     (b) If by 11:00 a.m., New York City time, on the Business Day following the Repurchase Date or
the Fundamental Change Date, as the case may be, the Trustee (or other Paying Agent appointed by
the Company) holds money sufficient to make payment on all the Notes or portions thereof that are
to be repurchased, then (i) such Notes will cease to be outstanding and interest will cease to
accrue on such Notes (whether or not book-entry transfer of the Notes has been made or the Notes
have been delivered to the Trustee or Paying Agent) and (ii) all other rights of the holders of
such Notes will terminate (other than the right to receive the Repurchase Price or Fundamental
Change Repurchase Price, as the case may be, upon delivery or transfer of the Notes).

     (c) Upon surrender of a Note that is to be repurchased in part pursuant to Section 9.01 or
Section 9.02, as applicable, the Company shall execute and the Trustee shall authenticate and
deliver to the holder a new Note in an authorized denomination equal in principal amount to the
unrepurchased portion of the Note surrendered.

     (ii) following delivery of an Officers Certificate by the Company to the Trustee to the

[FORM OF REVERSE OF NOTE]

BRISTOW GROUP INC.

3.00% Convertible Senior Note due 2038

     This Note is one of a duly authorized issue of Securities of the Company, designated as its
3.00% Convertible Senior Notes due 2038 (herein called the “Notes”), issued or to be issued under
and pursuant to an Indenture dated as of June 17, 2008 by and among the Company, certain
subsidiaries of the Company named therein and U.S. Bank National Association (herein called the
“Trustee”) (herein called the “Original Indenture”), as supplemented by the First Supplemental
Indenture dated as of June 17, 2008 by and among the Company, the Trustee and the Subsidiary
Guarantors named therein (herein called the “First Supplemental Indenture” and the Original
Indenture, as supplemented by the First Supplemental Indenture, the “Indenture”) to which Indenture
reference is hereby made for a description of the rights, limitations of rights, obligations,
duties and immunities thereunder of the Trustee, the Company and the holders of the Notes.
Additional Notes may be issued in an unlimited aggregate principal amount, subject to certain
conditions specified in the Indenture.

     In case an Event of Default, as defined in the Indenture, shall have occurred and be
continuing, except as set forth in Section 4.02 of the Supplemental Indenture, the principal of,
premium, if any, and interest on all Notes may be declared, by either the Trustee or Noteholders of
not less than 25% in aggregate principal amount of Notes then outstanding, and upon said
declaration shall become, due and payable, in the manner, with the effect and subject to the
conditions provided in the Indenture.

     Subject to the terms and conditions of the Indenture, the Company will make all payments and
deliveries in respect of the Fundamental Change Repurchase Price, the Repurchase Price and
Redemption Price and the principal amount on the Maturity Date, as the case may be, to the holder
who surrenders a Note to a Paying Agent to collect such payments in respect of the Note. The
Company will pay cash amounts in money of the United States that at the time of payment is legal
tender for payment of public and private debts.

     The Indenture contains provisions permitting the Company and the Trustee in certain
circumstances, without the consent of the holders of the Notes, and in other circumstances, with
the consent of the holders of not less than a majority of outstanding principal amount of the
Notes, evidenced as in the Indenture provided, to execute supplemental indentures modifying the
terms of the Indenture and the Notes as described therein. It is also provided in the Indenture
that, subject to certain exceptions, the holders of a majority of outstanding principal amount of
the Notes may on behalf of the holders of all of the Notes waive any past Default or Event of
Default under the Indenture and its consequences.

     No reference herein to the Indenture and no provision of this Note or of the Indenture shall
alter or impair the obligation of the Company, which is absolute and unconditional, to pay the
principal of, premium, if any, and accrued and unpaid interest on this Note at the place, at the
respective times, at the rate and in the lawful money herein prescribed.

A-4

 

     The Notes are issuable in registered form without coupons in denominations of $1,000 principal
amount and integral multiples thereof. At the office or agency of the Company referred to on the
face hereof, and in the manner and subject to the limitations provided in the Indenture, Notes may
be exchanged for a like aggregate principal amount of Notes of other authorized denominations,
without payment of any service charge but, if required by the Company or Trustee, with payment of a
sum sufficient to cover any tax, assessments or other governmental charges that may be imposed in
connection therewith as a result of the name of the Noteholder of the new Notes issued upon such
exchange of Notes being different from the name of the Noteholder of the old Notes surrendered for
such exchange.

     The Notes are not subject to redemption through the operation of any sinking fund.

     Upon the occurrence of a Fundamental Change and on each of June 15, 2015, June 15, 2020, June
15, 2025, June 15, 2030 and June 15, 2035, the holder has the right, at such holder’s option, to
require the Company to repurchase all of such holder’s Notes or any portion thereof (in principal
amounts of $1,000 or integral multiples thereof) at the price specified in the Indenture.

     On or after June 15, 2015, the Notes are redeemable, in whole or in part, for cash at any time
at the Company’s option at the price specified in the Indenture.

     Subject to the provisions of the Indenture, the holder hereof has the right, at its option,
during certain periods and upon the occurrence of certain conditions specified in the Indenture,
prior to the close of business on the Business Day immediately preceding the Maturity Date, to
convert any Notes or portion thereof that is $1,000 or an integral multiple thereof, into cash and
shares of Common Stock, if any, based on the Applicable Conversion Rate specified in the Indenture,
as adjusted from time to time as provided in the Indenture.

     The Notes are guaranteed by the Subsidiary Guarantors as described in the Indenture.

     Terms used in this Note and defined in the Indenture are used herein as therein defined.
