(a) Except as otherwise provided pursuant to this Section 2.02, the Securities are issuable in
fully registered form without coupons in substantially the form of Exhibit A hereto, with such
applicable legends as are provided for in Section 2.03. The Securities are not issuable in bearer
form. The terms and provisions contained in the form of Security shall constitute, and are hereby
expressly made, a part of this Indenture and to the extent applicable, the Company and the Trustee,
by their execution and delivery of this Indenture, expressly agree to such terms and provisions and
to be bound thereby. Any of the Securities may have such letters, numbers or other marks of
identification and such notations, legends and endorsements as the officers executing the same may
approve (execution thereof to be conclusive evidence of such approval) and as are not inconsistent
with the provisions of this Indenture, or as may be required to comply with any law or with any
rule or regulation made pursuant thereto or with any rule or regulation of any securities exchange
or automated quotation system on which the Securities may be listed or designated for issuance, or
to conform to usage.

(b) The Securities shall be issued initially in the form of one or more permanent Global
Securities, with the applicable legends as provided in Section 2.03. Each Global Security shall be
duly executed by the Company and authenticated and delivered by the Trustee, and shall be
registered in the name of DTC or its nominee and retained by the Trustee, as Securities Custodian,
at its corporate trust office, for credit to the accounts of the Agent Members holding the
Securities evidenced thereby. The aggregate principal amount of the Global Securities may from
time to time be increased or decreased by adjustments made on the records of the Trustee, as
Securities Custodian, and of DTC or its nominee, as hereinafter provided.

Section 2.03 . Legends. Each Security issued hereunder shall, upon issuance, bear the legend
set forth in Section 2.03(i), and each Common Stock certificate representing shares of the Common
Stock issued upon conversion of any Security issued hereunder, shall, upon issuance, unless as
otherwise set forth below, bear the legend set forth in Section 2.03(ii) (each such legend, a
“Restricted Securities Legend”), and such legend shall not be removed except as provided in Section
2.03(iii). Each Security that bears or is required to bear the Restricted Securities Legend set
forth in Section 2.03(i) (together with each Common Stock certificate representing shares of the
Common Stock issued upon conversion of such Security that bears or is required to bear the
Restricted Securities Legend set forth in Section 2.03(ii), collectively, the “Restricted
Securities”) shall be subject to the restrictions on transfer set forth in this Section 2.03
(including the Restricted Securities Legend set forth below), and the Holder of each such
Restricted Security, by such Holder’s acceptance thereof, shall be deemed to have agreed to be
bound by all such restrictions on transfer.

As used in Section 2.03, the term “transfer” encompasses any sale, pledge, transfer or other
disposition whatsoever of any Restricted Security.

(i) Restricted Securities Legend for Securities. Except as provided in Section
2.03(iii), any certificate evidencing such Security (and all Securities issued in exchange
therefor or substitution thereof, other than stock certificates representing shares of the
Common Stock, if any, issued upon conversion thereof which shall bear the legend set forth
in Section 2.03(ii), if applicable) shall bear a Restricted Securities Legend in
substantially the following form:

“THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE UNITED STATES SECURITIES ACT OF 1933, AS
AMENDED (THE “SECURITIES ACT”), AND ACCORDINGLY, MAY NOT BE OFFERED OR SOLD EXCEPT AS SET FORTH
IN THE FOLLOWING SENTENCE. BY ITS ACQUISITION HEREOF, THE HOLDER AGREES (1) THAT IT WILL NOT
RESELL OR OTHERWISE TRANSFER THE SECURITY EVIDENCED HEREBY OR THE COMMON STOCK ISSUABLE UPON
CONVERSION OF SUCH SECURITY, EXCEPT (A) TO THE COMPANY; (B) UNDER A REGISTRATION STATEMENT THAT
HAS BEEN DECLARED EFFECTIVE UNDER THE SECURITIES ACT; (C) TO A PERSON THE SELLER REASONABLY
BELIEVES IS A QUALIFIED INSTITUTIONAL BUYER (AS DEFINED IN RULE 144A ADOPTED UNDER THE
SECURITIES ACT) THAT IS PURCHASING FOR ITS OWN ACCOUNT OR FOR THE ACCOUNT OF ANOTHER QUALIFIED
INSTITUTIONAL BUYER AND TO WHOM NOTICE IS GIVEN THAT THE TRANSFER IS BEING MADE IN RELIANCE ON
RULE 144A, ALL IN COMPLIANCE WITH RULE 144A (IF AVAILABLE); OR (D) UNDER ANY OTHER AVAILABLE
EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT; AND (2) IT WILL, PRIOR TO
ANY TRANSFER OF THIS SECURITY FURNISH TO THE TRUSTEE AND THE ISSUER SUCH CERTIFICATIONS, LEGAL
OPINIONS OR OTHER INFORMATION AS MAY BE REQUIRED PURSUANT TO THE INDENTURE TO CONFIRM THAT SUCH
TRANSFER IS BEING MADE PURSUANT TO AN EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE
REGISTRATION REQUIREMENTS OF THE SECURITIES ACT.

(ii) Restricted Securities Legend for the Common Stock Issued Upon Conversion of the
Securities. Each stock certificate representing Common Stock issued upon conversion of
Securities bearing a Restricted Securities Legend will, subject to the availability of a
Shelf Registration Statement and registration thereunder as set forth in the Registration
Rights Agreement, bear the following legend:

“THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE UNITED STATES SECURITIES ACT OF 1933, AS
AMENDED (THE “SECURITIES ACT”), AND ACCORDINGLY, MAY NOT BE OFFERED OR SOLD EXCEPT AS SET FORTH
IN THE FOLLOWING SENTENCE. BY ITS ACQUISITION HEREOF, THE HOLDER AGREES (1) THAT IT WILL NOT
RESELL OR OTHERWISE TRANSFER THE SECURITY EVIDENCED HEREBY, EXCEPT (A) TO THE ISSUER; (B) UNDER
A REGISTRATION STATEMENT THAT HAS BEEN DECLARED EFFECTIVE UNDER THE SECURITIES ACT; (C) TO A
PERSON THE SELLER REASONABLY BELIEVES IS A QUALIFIED INSTITUTIONAL BUYER (AS DEFINED IN RULE
144A ADOPTED UNDER THE SECURITIES ACT) THAT IS PURCHASING FOR ITS OWN ACCOUNT OR FOR THE
ACCOUNT OF ANOTHER QUALIFIED INSTITUTIONAL BUYER AND TO WHOM NOTICE IS GIVEN THAT THE TRANSFER
IS BEING MADE IN RELIANCE ON RULE 144A, ALL IN COMPLIANCE WITH RULE 144A (IF AVAILABLE); OR (D)
UNDER ANY OTHER AVAILABLE EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT;
AND (2) IT WILL, PRIOR TO ANY TRANSFER OF THIS SECURITY FURNISH TO THE TRANSFER AGENT AND THE
ISSUER SUCH CERTIFICATIONS, LEGAL OPINIONS OR OTHER INFORMATION AS MAY BE REQUIRED TO CONFIRM
THAT SUCH TRANSFER IS BEING MADE PURSUANT TO AN EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT
TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT.

(iii) Removal of the Restricted Securities Legends. The Restricted Securities Legend
may be removed from any Security or any Common Stock certificate representing shares of
the Common Stock issued upon conversion of any Security if there is delivered to the
Company such satisfactory evidence, which may include an opinion of independent counsel,
as may be reasonably required by the Company, that neither such legend nor the
restrictions on transfer set forth therein are required to ensure that transfers of such
Security or shares of the Common Stock issued upon conversion of Securities, as the case
may be, will not violate the registration requirements of the Securities Act or the
qualification requirements under any state securities laws. Upon provision of such
satisfactory evidence, at the written direction of the Company, (x) in the case of a
Security, the Trustee shall authenticate and deliver in exchange for such Security another
Security or Securities having an equal aggregate principal amount that does not bear such
legend or (y) in the case of a Common Stock certificate representing shares of the Common
Stock, the transfer agent for the Common Stock shall authenticate and deliver in exchange
for the Common Stock certificate or certificates representing such shares of Common Stock
bearing such legend, one or more new Common Stock certificates representing a like
aggregate number of shares of Common Stock that do not bear such legend. If the
Restricted Securities Legend has been removed from a Security or Common Stock certificates
representing shares of the Common Stock issued upon conversion of any Security as provided
above, no other Security issued in exchange for all or any part of such Security, or no
other Common Stock certificates issued in exchange for such Common Stock, shall bear such
legend, unless the Company has reasonable cause to believe that such other Security is a
“restricted security” (or such shares of Common Stock are “restricted securities”) within
the meaning of Rule 144 and instructs the Trustee in writing to cause a Restricted
Securities Legend to appear thereon.

Any Security (or Security issued in exchange or substitution therefor) as to which the
conditions for removal of the Restricted Securities Legend set forth in Section 2.03(i) as set
forth therein have been satisfied may, upon surrender of such Security for exchange to the
Registrar in accordance with the provisions of Section 2.08, be exchanged for a new Security or
Securities, of like tenor and aggregate principal amount, which shall not bear the Restricted
Securities Legend required by Section 2.03(i).

Any Common Stock certificate representing shares of Common Stock issued upon conversion of any
Security as to which the conditions for removal of the Restricted Securities Legend set forth in
Section 2.03(ii) have been satisfied may, upon surrender of the Common Stock certificates
representing such shares of Common Stock for exchange in accordance with the procedures of the
transfer agent for the Common Stock, be exchanged for a new Common Stock certificate or
certificates representing a like aggregate number of shares of Common Stock, which shall not bear
the Restricted Securities Legend.

(iv) Global Security Legend. Each Global Security shall also bear the following
legend (the “Global Security Legend”) on the face thereof:

“UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST
COMPANY, A NEW YORK CORPORATION (“DTC”), NEW YORK, NEW YORK, TO THE COMPANY OR ITS AGENT FOR
REGISTRATION OF TRANSFER, EXCHANGE OR PAYMENT, AND ANY CERTIFICATE ISSUED IS REGISTERED IN THE
NAME OF CEDE & CO. OR IN SUCH OTHER NAME AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC
(AND ANY PAYMENT IS MADE TO CEDE & CO. OR TO SUCH OTHER ENTITY AS IS REQUESTED BY AN AUTHORIZED
REPRESENTATIVE OF DTC), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR
TO ANY PERSON IS WRONGFUL INASMUCH AS THE REGISTERED OWNER HEREOF, CEDE & CO., HAS AN INTEREST
HEREIN.

TRANSFERS OF THIS GLOBAL SECURITY SHALL BE LIMITED TO TRANSFERS IN WHOLE, BUT NOT IN PART, TO
NOMINEES OF DTC OR TO A SUCCESSOR THEREOF OR SUCH SUCCESSOR’S NOMINEE AND TRANSFERS OF PORTIONS
OF THIS GLOBAL SECURITY SHALL BE LIMITED TO TRANSFERS MADE IN ACCORDANCE WITH THE RESTRICTIONS
SET FORTH IN THE INDENTURE REFERRED TO IN THE TERMS OF SECURITIES ATTACHED HERETO.”

(v) Legend for Definitive Securities. Definitive Securities, in addition to the
legend set forth in Section 2.03(i) or (ii)Section 2.03(ii), will also bear a legend
substantially in the following form:

“THIS SECURITY WILL NOT BE ACCEPTED IN EXCHANGE FOR A BENEFICIAL INTEREST IN A GLOBAL SECURITY
UNLESS THE HOLDER OF THIS SECURITY, SUBSEQUENT TO SUCH EXCHANGE, WILL HOLD NO SECURITIES.”

Section 2.04 . Execution and Authentication. One Officer shall sign the Securities for the
Company by manual or facsimile signature. If an Officer whose signature is on a Security no longer
holds that office at the time the Trustee authenticates the Security, the Security shall be valid
nevertheless.

A Security shall not be valid until an authorized signatory of the Trustee manually
authenticates the Security. The signature of the Trustee on a Security shall be conclusive
evidence that such Security has been duly and validly authenticated and issued under this
Indenture. A Security shall be dated the date of its authentication.

At any time and from time to time after the execution and delivery of this Indenture, the
Company may deliver Securities executed by the Company in an unlimited aggregate principal amount
to the Trustee for authentication, together with a written order of the Company signed by two
Officers or by an Officer and either an Assistant Treasurer or an Assistant Secretary of the
Company (the “Company Order”) for the authentication and delivery of such Securities, and the
Trustee in accordance with such Company Order shall authenticate and deliver such Securities as in
this Indenture provided and not otherwise. All Securities issued on the Issue Date shall be
identical in all respects with any such Securities authenticated and delivered thereafter, other
than issue dates, the date from which interest accrues, appropriate CUSIP numbers or other
identifying notations and any changes relating thereto. Notwithstanding anything to the contrary
contained in this Indenture, subject to Section 2.12, all Securities issued under this Indenture
shall vote and consent together on all matters as one class and no series of Securities will have
the right to vote or consent as a separate class on any matter.

The Trustee may appoint an agent (the “Authenticating Agent”) reasonably acceptable to the
Company to authenticate the Securities. Initially, the Trustee will act as the Authenticating
Agent. Any such instrument shall be evidenced by an instrument signed by a Trust Officer of the
Trustee, a copy of which shall be furnished to the Company. Unless limited by the terms of such
appointment, any such Authenticating Agent may authenticate Securities whenever the Trustee may do
so. Each reference in this Indenture to authentication by the Trustee includes authentication by
the Authenticating Agent. An Authenticating Agent has the same rights as any Registrar, Paying
Agent or agent for service of notices and demands.

In case the Company, pursuant to Article 4, shall be consolidated or merged with or into any
other Person or shall convey, transfer, lease or otherwise dispose of its properties and assets
substantially as an entirety to any Person, and the successor Person resulting from such
consolidation, or surviving such merger, or into which the Company shall have been merged, or the
Person which shall have received a conveyance, transfer, lease or other disposition as aforesaid,
shall have executed an indenture supplemental hereto with the Trustee pursuant to Article 4, any of
the Securities authenticated or delivered prior to such consolidation, merger, conveyance,
transfer, lease or other disposition may, from time to time, at the request of the successor
Person, be exchanged for other Securities executed in the name of the successor Person with such
changes in phraseology and form as may be appropriate, but otherwise in substance of like tenor as
the Securities surrendered for such exchange and of like principal amount; and the Trustee, upon
Company Order of the successor Person, shall authenticate and deliver Securities as specified in
such order for the purpose of such exchange. If Securities shall at any time be authenticated and
delivered in any new name of a successor Person pursuant to this Section 2.04 in exchange or
substitution for or upon registration of transfer of any Securities, such successor Person, at the
option of the Holders but without expense to them, shall provide for the exchange of all Securities
at the time outstanding for Securities authenticated and delivered in such new name.

Section 2.05 . Registrar and Paying Agent. The Company shall maintain an office or agency
where Securities may be presented for registration of transfer or for exchange (the “Registrar”)
and an office or agency where Securities may be presented for payment (the “Paying Agent”). The
Registrar shall keep a register of the Securities and of their transfer and exchange (the
“Securities Register”). The Company may have one or more co-registrars and one or more additional
paying agents. The term “Paying Agent” includes any additional paying agent and the term
“Registrar” includes any co-registrar.

The Company shall enter into an appropriate agency agreement with any Registrar, Paying Agent
or co-registrar not a party to this Indenture, which shall incorporate the terms of the TIA. The
agreement shall implement the provisions of this Indenture that relate to such agent. The Company
shall notify the Trustee of the name and address of each such agent. If the Company fails to
maintain a Registrar or Paying Agent, the Trustee shall act as such and shall be entitled to
appropriate compensation therefor pursuant to Section 7.07. The Company or any of its domestically
organized, wholly owned Subsidiaries may act as Paying Agent, Registrar, co registrar or transfer
agent.

The Company initially appoints the Trustee as Registrar and Paying Agent for the Securities.
The Company may remove any Registrar or Paying Agent upon written notice to such Registrar or
Paying Agent and to the Trustee; provided, however, that no such removal shall become effective
until (i) acceptance of any appointment by a successor as evidenced by an appropriate agreement
entered into by the Company and such successor Registrar or successor Paying Agent, as the case may
be, and delivered to the Trustee or (ii) notification to the Trustee that the Trustee shall serve
as Registrar or Paying Agent until the appointment of a successor in accordance with clause (i)
above. The Registrar or Paying Agent may resign at any time upon written notice to the Company and
the Trustee.

Section 2.06 . Paying Agent to Hold Money in Trust. By no later than 11:00 a.m., New York
City time, on the date on which any principal of or interest and Additional Interest, if any, on
any Security is due and payable, the Company shall deposit with the Paying Agent a sum sufficient
in immediately available funds to pay such principal or interest (including any Additional
Interest), when due. The Company shall require each Paying Agent (other than the Trustee) to agree
in writing that such Paying Agent shall hold in trust for the benefit of Holders or the Trustee all
money held by such Paying Agent for the payment of principal of or interest (including any
Additional Interest), on the Securities and shall notify the Trustee in writing of any default by
the Company in making any such payment. If the Company or a Subsidiary acts as Paying Agent, it
shall segregate the money held by it as Paying Agent and hold it as a separate trust fund. The
Company at any time may require a Paying Agent (other than the Trustee) to pay all money held by it
to the Trustee and to account for any funds disbursed by such Paying Agent. Upon complying with
this Section 2.06, the Paying Agent (if other than the Company or a Subsidiary) shall have no
further liability for the money delivered to the Trustee. Upon any bankruptcy, reorganization or
similar proceeding with respect to the Company, the Trustee shall serve as Paying Agent for the
Securities.

Section 2.07 . Holder Lists. The Trustee shall preserve in as current a form as is
reasonably practicable the most recent list available to it of the names and addresses of Holders
and shall otherwise comply with TIA § 312(a). If the Trustee is not the Registrar, or to the
extent otherwise required under the TIA, the Company, shall furnish or cause the Registrar to
furnish to the Trustee, in writing at least five Business Days before each interest payment date
and at such other times as the Trustee may request in writing, a list in such form and as of such
date as the Trustee may reasonably require of the names and addresses of Holders and the Company
shall otherwise comply with TIA § 312(a).

Section 2.08 . General Provisions Relating to Transfer and Exchange. The Securities are
issuable only in registered form. A Holder may transfer a Security only by written application to
the Registrar stating the name of the proposed transferee and otherwise complying with the terms of
this Indenture. No such transfer shall be effected until, and such transferee shall succeed to the
rights of a Holder only upon, final acceptance and registration of the transfer by the Registrar in
the Securities Register. Furthermore, any Holder of a Global Security shall, by acceptance of such
Global Security, agree that transfers of beneficial interests in such Global Security may be
effected only through a book-entry system maintained by the Holder of such Global Security (or its
agent) and that ownership of a beneficial interest in the Global Security shall be required to be
reflected in a book-entry.

When Securities are presented to the Registrar with a request to register the transfer or to
exchange them for an equal aggregate principal amount of Securities of other authorized
denominations, the Registrar shall register the transfer or make the exchange as requested if its
requirements for such transactions are met (including that such Securities are duly endorsed or
accompanied by a written instrument of transfer duly executed by the Holder thereof or by an
attorney who is authorized in writing to act on behalf of the Holder). Subject to Section 2.04, to
permit registrations of transfers and exchanges, the Company shall execute and the Trustee shall
authenticate Securities at the Registrar’s request. No service charge shall be made for any
registration of transfer or exchange or redemption of the Securities, but the Company may require
payment of a sum sufficient to cover any transfer tax or similar governmental charge payable in
connection therewith (other than any such transfer taxes or other similar governmental charge
payable upon exchanges in connection with which a Security is issued to a Person other than the
Holder submitting the Security for exchange).

Neither the Company nor the Registrar shall be required to exchange or register a transfer of
any Securities:

(a) for a period of 15 days prior to the mailing of a notice of redemption of Securities
selected for redemption under Article 5;

(b) so selected for redemption or, if a portion of any Security is selected for redemption,
the portion thereof selected for redemption; or

(c) surrendered for conversion or, if a portion of any Security is surrendered for conversion,
the portion thereof surrendered for conversion.

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

Section 2.09 . Book-Entry Provisions for the Global Securities. (a) The Global Securities
initially shall:

(i) be registered in the name of DTC (or a nominee thereof);

(ii) be delivered to the Trustee as Securities Custodian;

(iii) bear the Restricted Securities Legend set forth in Section 2.03(i); and

(iv) bear the Global Security Legend set forth in Section 2.03(iv).

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

(b) The Holder of a Global Security may grant proxies and otherwise authorize any Person,
including Agent Members and Persons that may hold interests through Agent Members, to take any
action which a Holder is entitled to take under this Indenture or the Securities.

(c) A Global Security may not be transferred, in whole or in part, to any Person other than
DTC (or a nominee thereof), and no such transfer to any such other Person may be registered.
Beneficial interests in a Global Security may be transferred in accordance with the rules and
procedures of DTC and the provisions of Section 2.10.

(d) If at any time:

(i) DTC notifies the Company in writing that it is unwilling or unable to continue to
act as depositary for the Global Securities and a successor depositary for the Global
Securities is not appointed by the Company within 90 days of such notice;

(ii) DTC ceases to be registered as a “clearing agency” under the Exchange Act and a
successor depositary for the Global Securities is not appointed by the Company within 90
days of such cessation;

(iii) the Company, at its option, notifies the Trustee in writing that it elects to
cause the issuance of the Definitive Securities under this Indenture in exchange for all
or any part of the Securities represented by a Global Security or Global Securities,
subject to the procedures of DTC; or

(iv) an Event of Default has occurred and is continuing and the Registrar has
received a request from DTC for the issuance of Definitive Securities in exchange for such
Global Security or Global Securities;

DTC shall surrender such Global Security or Global Securities to the Trustee for cancellation and
the Company shall execute, and the Trustee, upon receipt of an Officers’ Certificate and Company
Order for the authentication and delivery of Securities, shall authenticate and deliver in exchange
for such Global Security or Global Securities, Definitive Securities in an aggregate principal
amount equal to the aggregate principal amount of such Global Security or Global Securities. Such
Definitive Securities shall be registered in such names as DTC shall identify in writing as the
beneficial owners of the Securities represented by such Global Security or Global Securities (or
any nominee thereof).

(e) Notwithstanding the foregoing, in connection with any transfer of beneficial interests in
a Global Security to the beneficial owners thereof pursuant to Section 2.09(d), the Registrar shall
reflect on its books and records the date and a decrease in the principal amount of such Global
Security in an amount equal to the principal amount of the beneficial interests in such Global
Security to be transferred.

Section 2.10 . Special Transfer Provisions. Unless a Security is no longer a Restricted
Security, the following provisions shall apply to any sale, pledge or other transfer of such
Securities:

(a) Transfer of Securities to a QIB. The following provisions shall apply with respect to the
registration of any proposed transfer of Securities to a QIB:

(i) If the Securities to be transferred consist of a beneficial interest in the
Global Securities, the transfer of such interest may be effected only through the
book-entry systems maintained by DTC.

(ii) If the Securities to be transferred consist of Definitive Securities, the
Registrar shall register the transfer if such transfer is being made by a proposed
transferor who has checked the box provided for on the form of Security stating (or has
otherwise advised the Company and the Registrar in writing) that the sale has been made in
compliance with the provisions of Rule 144A to a transferee who has signed a certification
stating or has otherwise advised the Company and the Registrar in writing that:

(A) it is purchasing the Securities for its own account or an account with
respect to which it exercises sole investment discretion;

(B) it and any such account is a QIB within the meaning of Rule 144A;

(C) it is aware that the sale to it is being made in reliance on Rule 144A;

(D) it acknowledges that it has received such information regarding the
Company as it has requested pursuant to Rule 144A or has determined not to
request such information; and

(E) it is aware that the transferor is relying upon its foregoing
representations in order to claim the exemption from registration provided by
Rule 144A.

(b) General. By its acceptance of any Security bearing the Restricted Securities Legend, each
Holder of such a Security acknowledges the restrictions on transfer of such Security set forth in
this Indenture and agrees that it will transfer such Security only as provided in this Indenture.
The Registrar shall not register a transfer of any Security unless such transfer complies with the
restrictions on transfer of such Security set forth in this Indenture. The Registrar shall be
entitled to receive and rely on written instructions from the Company verifying that such transfer
complies with such restrictions on transfer. In connection with any transfer of Securities, each
Holder agrees by its acceptance of the Securities to furnish the Registrar or the Company such
certifications, legal opinions or other information as either of them may reasonably require to
confirm that such transfer is being made pursuant to an exemption from, or a transaction not
subject to, the registration requirements of the Securities Act; provided that the Registrar shall
not be required to determine (but may rely on a determination made by the Company with respect to)
the sufficiency of any such certifications, legal opinions or other information.

The Registrar shall retain copies of all certifications, letters, notices and other written
communications received pursuant to Section 2.09 hereof or this Section 2.10. The Company shall
have the right to inspect and make copies of all such letters, notices or other written
communications at any reasonable time upon the giving of reasonable written notice to the
Registrar.

Section 2.11 . Mutilated, Destroyed, Lost or Stolen Securities. If a mutilated Security is
surrendered to the Registrar or if the Holder of a Security claims that the Security has been lost,
destroyed or wrongfully taken, the Company shall issue and the Trustee shall authenticate a
replacement Security if the requirements of Section 8-405 of the UCC are met, such that the Holder
(a) notifies the Company or the Trustee within a reasonable time after such Holder has notice of
such loss, destruction or wrongful taking and the Registrar has not registered a transfer prior to
receiving such notification, (b) makes such request to the Company or Trustee prior to the Security
being acquired by a protected purchaser as defined in Section 8-303 of the UCC and (c) satisfies
any other reasonable requirements of the Trustee. Such Holder shall furnish an indemnity bond
sufficient in the judgment of the Company and the Trustee to protect the Company, the Trustee, the
Paying Agent and the Registrar from any loss which any of them may suffer if a Security is
replaced, and, in the absence of notice to the Company or the Trustee that such Security has been
acquired by a bona fide purchaser, the Company shall execute and upon Company Order the Trustee
shall authenticate and make available for delivery, in exchange for any such mutilated Security or
in lieu of any such destroyed, lost or stolen Security, a new Security of like tenor and principal
amount, bearing a number not contemporaneously outstanding.

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

Upon the issuance of any new Security under this Section 2.11, the Company may require the
payment by the Holder of a sum sufficient to cover any tax or other governmental charge that may be
imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee)
in connection therewith.

Every new Security issued pursuant to this Section 2.11 in lieu of any mutilated, destroyed,
lost or stolen Security shall constitute an original additional contractual obligation of the
Company and any other obligor upon the Securities, whether or not the mutilated, destroyed, lost or
stolen Security shall be at any time enforceable by anyone, and shall be entitled to all benefits
of this Indenture equally and ratably with any and all other Securities duly issued hereunder.

The provisions of this Section 2.11 are exclusive and shall preclude (to the extent lawful)
all other rights and remedies with respect to the replacement or payment of mutilated, destroyed,
lost or stolen Securities.

Section 2.12 . Outstanding Securities. Securities outstanding at any time are all Securities
authenticated by the Trustee except for those cancelled by it, those delivered to it for
cancellation and those described in this Section 2.12 as not outstanding. A Security does not
cease to be outstanding in the event the Company or a Subsidiary of the Company holds the Security;
provided, however, that (i) for purposes of determining which Securities are outstanding for
consent or voting purposes hereunder, the provisions of Section 13.06 shall apply and (ii) in
determining whether the Trustee shall be protected in making a determination whether the Holders of
the requisite principal amount of outstanding Securities are present at a meeting of Holders of
Securities for quorum purposes or have consented to or voted in favor of any request, demand,
authorization, direction, notice, consent, waiver, amendment or modification hereunder, or relying
upon any such quorum, consent or vote, only Securities which a Trust Officer of the Trustee
actually knows to be held by the Company or an Affiliate of the Company shall not be considered
outstanding.

If a Security is replaced or paid pursuant to Section 2.11, it ceases to be outstanding unless
the Trustee and the Company receive proof satisfactory to them that the replaced Security is held
by a bona fide purchaser.

If the Paying Agent segregates and holds in trust, in accordance with this Indenture, on a
Redemption Date or at Stated Maturity, money sufficient to pay all principal and interest payable
on that date with respect to the Securities (or portions thereof) to be redeemed or maturing, as
the case may be, and the Paying Agent is not prohibited from paying such money to the Holders on
that date pursuant to the terms of this Indenture, then on and after that date such Securities (or
portions thereof) cease to be outstanding and interest on them ceases to accrue.

Section 2.13 . Temporary Securities. In the event that Definitive Securities are to be
issued under the terms of this Indenture, until such Definitive Securities are ready for delivery,
the Company may prepare and upon receipt of a Company Order 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 upon receipt of a Company Order the
Trustee shall authenticate Definitive Securities. After the preparation of Definitive Securities,
the temporary Securities shall be exchangeable for Definitive Securities upon surrender of the
temporary Securities at any office or agency maintained by the Company for that purpose and such
exchange shall be without charge to the Holder. Upon surrender for cancellation of any one or more
temporary Securities, the Company shall execute, and the Trustee shall authenticate and make
available for delivery in exchange therefor, one or more Definitive Securities representing an
equal principal amount of Securities. Until so exchanged, the Holder of temporary Securities shall
in all respects be entitled to the same benefits under this Indenture as a Holder of Definitive
Securities.

Section 2.14 . Cancellation. The Company at any time may deliver Securities to the Trustee
for cancellation. The Registrar and the Paying Agent shall forward to the Trustee any Securities
surrendered to them for registration of transfer, exchange or payment. The Trustee and no one else
shall cancel all Securities surrendered for registration of transfer, exchange, payment or
cancellation and dispose of such Securities in accordance with its internal policies and customary
procedures including delivery of a certificate (a “Certificate of Destruction”) describing such
Securities disposed (subject to the record retention requirements of the Exchange Act) or deliver
canceled Securities to the Company pursuant to written direction by an Officer. The Company may
not issue new Securities to replace Securities it has paid for or delivered to the Trustee for
cancellation for any reason other than in connection with a transfer or exchange.

At such time as all beneficial interests in a Global Security have either been exchanged for
Definitive Securities, transferred, redeemed, repurchased or canceled, such Global Security shall
be returned by DTC to the Trustee for cancellation or retained and canceled by the Trustee. At any
time prior to such cancellation, if any beneficial interest in a Global Security is exchanged for
Definitive Securities, transferred in exchange for an interest in another Global Security,
redeemed, repurchased or canceled, the principal amount of Securities represented by such Global
Security shall be reduced and an adjustment shall be made on the books and records of the Trustee
(if it is then the Securities Custodian for such Global Security) with respect to such Global
Security, by the Trustee or the Securities Custodian, to reflect such reduction.

Section 2.15 . Payment of Interest; Defaulted Interest. Interest (including any Additional
Interest) on any Security which is payable, and is punctually paid or duly provided for, on any
interest payment date shall be paid to the Person in whose name such Security (or one or more
predecessor Securities) is registered at the close of business on the Regular Record Date for such
payment at the office or agency of the Company maintained for such purpose pursuant to Section
2.05.

Any interest on any Security which is payable, but is not paid when the same becomes due and
payable and such nonpayment continues for a period of 30 days, shall forthwith cease to be payable
to the Holder on the Regular Record Date, and such defaulted interest and (to the extent lawful)
interest on such defaulted interest at the rate borne by the Securities (such defaulted interest
and interest thereon herein collectively called “Defaulted Interest”) shall be paid by the Company
at its election, in each case, as provided in clause (a) or (b) below:

(a) The Company may elect to make payment of any Defaulted Interest to the Persons in whose
names the Securities (or their respective predecessor Securities) are registered at the close of
business on a Special Record Date (as defined below) for the payment of such Defaulted Interest,
which shall be fixed in the following manner. The Company shall notify the Trustee in writing of
the amount of Defaulted Interest proposed to be paid on each Security and the date (not less than
30 days after such notice) of the proposed payment (the “Special Interest Payment Date”), and at
the same time the Company shall deposit with the Trustee an amount of money equal to the aggregate
amount proposed to be paid in respect of such Defaulted Interest or shall make arrangements
satisfactory to the Trustee for such deposit prior to the date of the proposed payment, such money
when deposited to be held in trust for the benefit of the Persons entitled to such Defaulted
Interest as in this clause provided. Thereupon the Trustee shall fix a record date (the “Special
Record Date”) for the payment of such Defaulted Interest which shall be not more than 15 days and
not less than 10 days prior to the Special Interest Payment Date and not less than 10 days after
the receipt by the Trustee of the notice of the proposed payment. The Trustee shall promptly
notify the Company of such Special Record Date, and in the name and at the expense of the Company,
shall cause notice of the proposed payment of such Defaulted Interest and the Special Record Date
and Special Interest Payment Date therefor to be given in the manner provided for in Section 13.02,
not less than 10 days prior to such Special Record Date. Notice of the proposed payment of such
Defaulted Interest and the Special Record Date and Special Interest Payment Date therefor having
been so given, such Defaulted Interest shall be paid on the Special Interest Payment Date to the
Persons in whose names the Securities (or their respective predecessor Securities) are registered
at the close of business on such Special Record Date and shall no longer be payable pursuant to the
following clause (b).

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

Subject to the foregoing provisions of this Section 2.15, each Security delivered under this
Indenture upon registration of, transfer of or in exchange for or in lieu of any other Security
shall carry the rights to interest (including any Additional Interest) accrued and unpaid, and to
accrue, which were carried by such other Security.

Section 2.16 . Computation of Interest. Interest (including any Additional Interest) on the
Securities shall be computed on the basis of a 360-day year of twelve 30-day months.

Section 2.17 . CUSIP and ISIN Numbers. The Company in issuing the Securities may use “CUSIP”
and “ISIN” numbers (if then generally in use) and, if so, the Trustee shall use “CUSIP” and “ISIN”
numbers in notices of redemption as a convenience to Holders; provided, however, that any such
notice may state that no representation is made as to the correctness of such numbers either as
printed on the Securities or as contained in any notice of a redemption and that reliance may be
placed only on the other identification numbers printed on the Securities, and any such redemption
shall not be affected by any defect in or omission of such CUSIP or ISIN numbers. The Company
shall promptly notify the Trustee in writing of any change in the CUSIP and ISIN numbers.

ARTICLE 3

Covenants

Section 3.01 . Payment of Securities. The Company shall promptly pay the principal of and
interest (including any Additional Interest) on the Securities on the dates and in the manner
provided in the Securities and in this Indenture. Principal and interest (including any Additional
Interest) shall be considered paid on the date due if on such date the Trustee or the Paying Agent
holds in accordance with this Indenture immediately available funds sufficient to pay all principal
and interest (including any Additional Interest) then due and the Trustee or the Paying Agent, as
the case may be, is not prohibited from paying such money to the Holders on that date pursuant to
the terms of this Indenture.

The Company shall pay interest on overdue principal at the rate specified therefor in the
Securities, and it shall pay interest on overdue installments of interest at the same rate to the
extent lawful.

Notwithstanding anything to the contrary contained in this Indenture, the Company may, to the
extent it is required to do so by law, deduct or withhold income or other similar taxes imposed by
the United States of America from principal or interest (including any Additional Interest)
payments hereunder.

Section 3.02 . Financial Statements. In the event and for so long as the Company is not
subject to Section 13 or 15(d) of the Exchange Act, it shall file with the Trustee and cause to be
mailed to each Holder at such Holder’s registered address, upon the request of any Holder or
beneficial holder of the Securities or the Common Stock issued upon conversion thereof, and make
available to such Holder or beneficial holder of such Securities or Common Stock in connection with
any sale thereof and any prospective purchaser of Securities or Common Stock designated by such
Holder or beneficial holder, the information required pursuant to Rule 144A(d)(4) under the
Securities Act and it will take such further action as any Holder or beneficial holder of such
Securities or Common Stock may reasonably request, all to the extent required from time to time to
enable such Holder or beneficial holder to sell its Securities or Common Stock without registration
under the Securities Act within the limitation of the exemption provided by Rule 144A, as such Rule
may be amended from time to time.

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

Section 3.03 . Maintenance of Office or Agency. The Company will maintain an office or
agency where the Securities may be presented or surrendered for payment, where, if applicable, the
Securities may be surrendered for registration of transfer or exchange and where notices and
demands to or upon the Company in respect of the Securities and this Indenture may be served. The
Company will give prompt written notice to the Trustee of any change in the location of any such
office or agency. If at any time the Company shall fail to maintain any such required office or
agency or shall fail to furnish the Trustee with the address thereof, such presentations,
surrenders, notices and demands may be made or served at the Trustee, and the Company hereby
appoints the Trustee as its agent to receive all such presentations, surrenders, notices and
demands.

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

Section 3.04 . Corporate Existence. Except as otherwise provided in Article 4, the Company
will do or cause to be done all things necessary to preserve and keep in full force and effect
(i) its corporate existence and (ii) the material rights (charter and statutory), licenses and
franchises of the Company, except, in the case of clause (ii), to the extent the Board of Directors
of the Company otherwise reasonably determines it no longer desirable.

Section 3.05 . Payment of Taxes and Other Claims. The Company will pay or discharge or cause
to be paid or discharged, before the same shall become delinquent, (i) all material taxes,
assessments and governmental charges levied or imposed upon the Company or any Subsidiary or upon
the income, profits or property of the Company or any Subsidiary and (ii) all lawful claims for
labor, materials and supplies, which, if unpaid, might by law become a material liability or lien
upon the property of the Company or any Subsidiary; provided, however, that the Company shall not
be required to pay or discharge or cause to be paid or discharged any such tax, assessment, charge
or claim whose amount, applicability or validity is being contested in good faith by appropriate
proceedings and for which appropriate reserves, if necessary (in the good faith judgment of
management of the Company), are being maintained in accordance with GAAP or where the failure to
effect such payment will not be disadvantageous to the Holders.

Section 3.06 . Compliance Certificate. The Company shall deliver to the Trustee within 120
days after the end of each fiscal year of the Company an Officers’ Certificate, one of the signers
of which shall be the principal executive officer, principal financial officer or principal
accounting officer of the Company, stating that in the course of the performance by the signers of
their duties as Officers of the Company they would normally have knowledge of any Default or Event
of Default and whether or not the signers know of any Default or Event of Default that occurred
during such period. If they do, the certificate shall describe each Default or Event of Default,
its status and the action the Company is taking or proposes to take with respect thereto. The
Company also shall comply with TIA § 314(a)(4).

Section 3.07 . 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 purpose of this Indenture.

Section 3.08 . Statement by Officers as to Default. The Company shall deliver to the
Trustee, as soon as possible and in any event within 30 days after the Company becomes aware of the
occurrence of any Event of Default or an event which, with notice or the lapse of time or both,
would constitute an Event of Default, an Officers’ Certificate setting forth the details of such
Event of Default or Default, its status and the action which the Company proposes to take with
respect thereto.

Section 3.09 . Additional Interest. If Additional Interest is payable by the Company
pursuant to the Registration Rights Agreement, the Company shall deliver to the Trustee an
Officers’ Certificate to that effect stating (i) the amount of such Additional Interest that is
payable and (ii) the date on which such Additional Interest is payable. Unless and until a Trust
Officer of the Trustee receives such a certificate, the Trustee may assume without inquiry that no
Additional Interest is payable. If the Company has paid Additional Interest directly to the
persons entitled to it, the Company shall deliver to the Trustee an Officers’ Certificate setting
forth the particulars of such payment.

ARTICLE 4

Successor Company

Section 4.01 . Consolidation, Merger and Sale of Assets. The Company shall not consolidate
with or merge with or into, or convey, transfer or lease all or substantially all its assets to,
another Person, unless:

(a) the resulting, surviving or transferee Person (the “Successor Company”) if not the Company
shall be a corporation, partnership, trust or limited liability company organized and existing
under the laws of the United States of America, any State thereof or the District of Columbia and
the Successor Company (if not the Company) shall expressly assume, by supplemental indenture,
executed and delivered to the Trustee, in form satisfactory to the Trustee, all the obligations of
the Company under the Securities, this Indenture and, to the extent that it is otherwise still
operative, the Registration Rights Agreement;

(b) immediately after giving effect to such transaction, no Default or Event of Default shall
have occurred and be continuing; and

(c) the Company shall have delivered to the Trustee an Officers’ Certificate and an Opinion of
Counsel, stating that such consolidation, merger or transfer and such supplemental indenture, if
any, comply with this Indenture.

For purposes of this Section 4.01, the sale, lease, conveyance, assignment, transfer, or other
disposition of all or substantially all of the properties and assets of one or more Subsidiaries of
the Company, which properties and assets, if held by the Company instead of such Subsidiaries,
would constitute all or substantially all of the properties and assets of the Company on a
consolidated basis, shall be deemed to be the transfer of all or substantially all of the
properties and assets of the Company.

The Successor Company will succeed to, and be substituted for, and may exercise every right
and power of, the Company under this Indenture, but, in the case of a lease of all or substantially
all its assets, the Company will not be released from the obligation to pay the principal of and
interest (including any Additional Interest) on the Securities.

ARTICLE 5

Redemption of Securities

Section 5.01 . Optional Redemption. Prior to June 20, 2011, the Securities shall not be
redeemable. (i) On and after June 20, 2011 but prior to June 15, 2016 if the Last Reported Sale
Price of the Common Stock is greater than or equal to 130% of the Conversion Price then in effect
for at least 20 Trading Days within a period of 30 consecutive Trading Days ending on the Trading
Day prior to the date on which the notice of redemption is mailed, and (ii) on or after June 15,
2016, the Securities may be redeemed, as a whole or from time to time in part, subject to the
conditions set forth herein, at a price (the “Redemption Price”) equal to 100% of the principal
amount of Securities to be redeemed, plus accrued and unpaid interest (including any Additional
Interest) to but excluding the Redemption Date; provided that if the Redemption Date occurs after a
Regular Record Date for the payment of interest and on or prior to the related interest payment
date, the Redemption Price for any such Securities to be redeemed shall be 100% of the principal
amount of such Securities and accrued and unpaid interest (including any Additional Interest) shall
be paid to the Holder on such Regular Record Date.

Section 5.02 . Election to Redeem; Notice to Trustee. In case of any redemption at the
election of the Company, the Company shall, on or prior to the date that is 15 days prior to the
date on which notice is given to the Holders (unless a shorter notice shall be satisfactory to the
Trustee), notify the Trustee of such Redemption Date and of the principal amount of Securities to
be redeemed and shall deliver to the Trustee such documentation and records as shall enable the
Trustee to select the Securities to be redeemed pursuant to Section 5.03. Any such notice may be
cancelled at any time prior to notice of such redemption being mailed to any Holder and shall
thereby be void and of no effect.

Section 5.03 . Selection by Trustee of Securities to Be Redeemed. If less than all the
Securities are to be redeemed at any time pursuant to an optional redemption, the particular
Securities to be redeemed shall be selected by the Trustee, from the outstanding Securities not
previously called for redemption, by lot or on a pro rata basis among the classes of Securities or
by such other method as the Trustee shall deem fair and appropriate (and in such manner as is not
prohibited by applicable legal requirements) and which may provide for the selection for redemption
of portions of the principal of the Securities; provided, however, that no such partial redemption
shall reduce the portion of the principal amount of a Security not redeemed to less than $1,000.

The Trustee shall promptly notify the Company 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.

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

If any Securities selected for partial redemption are thereafter surrendered for conversion in
part before termination of the conversion right with respect to the portion of the Securities so
selected, the converted portion of such Securities shall be deemed (so far as may be), solely for
purposes of determining the aggregate principal amount of Securities to be redeemed by the Company,
to be the portion selected for redemption. Securities which have been converted during a selection
of Securities to be redeemed may be treated by the Trustee as outstanding for the purpose of such
selection. Nothing in this Section 5.03 shall affect the right of any Holder to convert any
Securities pursuant to Article 12 before the termination of the conversion right with respect
thereto.

Section 5.04 . Notice of Redemption. Notice of redemption shall be given in the manner
provided for in Section 13.02 not less than 45 nor more than 60 calendar days prior to the
Redemption Date, to each Holder of Securities to be redeemed. The Trustee shall give notice of
redemption in the Company’s name and at the Company’s expense; provided, however, that the Company
shall deliver to the Trustee an Officers’ Certificate requesting that the Trustee give such notice
at the Company’s expense and setting forth the information to be stated in such notice as provided
in the following items.

All notices of redemption shall state:

(a) the Redemption Date;

(b) the Redemption Price;

(c) the then current Conversion Rate and the related Observation Period for conversion of
Securities, and provide a statement that the Securities called for redemption may be converted at
any time before the close of business on the third Scheduled Trading Day prior to the Redemption
Date, and that Holders who wish to convert Securities must comply with the procedures in paragraph
7 of the Securities;

(d) if less than all outstanding Securities are to be redeemed, the identification of the
particular Securities (or portion thereof) to be redeemed, as well as the aggregate principal
amount of Securities to be redeemed and the aggregate principal amount of Securities to be
outstanding after such partial redemption;

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

(f) that on the Redemption Date the Redemption Price will become due and payable upon each
such Security, or the portion thereof, to be redeemed, and, unless the Company defaults in making
the redemption payment, that interest (including any Additional Interest) on Securities called for
redemption (or the portion thereof) will cease to accrue on and after said date;

(g) the place or places where such Securities are to be surrendered for payment of the
Redemption Price;

(h) the name and address of the Paying Agent and the Conversion Agent;

(i) that Securities called for redemption must be surrendered to the Paying Agent to collect
the Redemption Price;

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

(k) the paragraph of the Securities pursuant to which the Securities are to be redeemed.

Section 5.05 . Deposit of Redemption Price. Prior to any Redemption Date, the Company shall
deposit with the Trustee or with a Paying Agent (or, if the Company is acting as its own Paying
Agent, segregate and hold in trust as provided in Section 2.06) an amount of money sufficient to
pay the Redemption Price of all the Securities which are to be redeemed on that date other than
Securities or portions of Securities called for redemption that are beneficially owned by the
Company and have been delivered by the Company to the Trustee for cancellation.

Section 5.06 . Securities Payable on Redemption Date. Notice of redemption having been given
as aforesaid, the Securities so to be redeemed shall, on the Redemption Date, become due and
payable at the Redemption Price, and from and after such date (unless the Company shall default in
the payment of the Redemption Price or accrued and unpaid interest (including any Additional
Interest)) such Securities shall cease to bear interest or Additional Interest. Upon surrender of
any such Security for redemption in accordance with said notice, such Security shall be paid by the
Company at the Redemption Price.

If any Security called for redemption shall not be so paid upon surrender thereof for
redemption, the principal shall, until paid, bear interest (including any Additional Interest) from
the Redemption Date at the rate borne by the Securities.

Section 5.07 . Securities Redeemed in Part. Any Security which is to be redeemed only in
part (pursuant to the provisions of this Article 5) shall be surrendered at the office or agency of
the Company maintained for such purpose pursuant to Section 3.03 (with, if the Company or the
Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory
to the Company and the Trustee duly executed by, the Holder thereof or such Holder’s attorney duly
authorized in writing), and the Company shall execute, and the Trustee shall authenticate and make
available for delivery to the Holder of such Security at the expense of the Company, a new Security
or Securities, of any authorized denomination as requested by such Holder, in an aggregate
principal amount equal to and in exchange for the unredeemed portion of the principal of the
Security so surrendered; provided that each such new Security will be in a principal amount of
$1,000 or multiple thereof.

ARTICLE 6

Defaults and Remedies

Section 6.01 . Events of Default. Each of the following is an “Event of Default”:

(a) default in any payment of interest or Additional Interest (as required by the Registration
Rights Agreement) on any Security when the same becomes due and payable, and such default continues
for a period of 30 days;

(b) default in the payment of the principal of any Security when the same becomes due and
payable at its Stated Maturity, upon optional redemption, upon required repurchase, upon
declaration or otherwise;

(c) failure by the Company to comply with its obligation to convert the Securities in
accordance with this Indenture, upon exercise of a Holder’s conversion right and such failure
continues for a period of five days;

(d) failure by the Company to give a Fundamental Change notice to Holders or notice to Holders
required pursuant to Section 12.01(a)(iv), in each case when due;

(e) failure by the Company to comply with any of its obligations under Article 4;

(f) default in the performance of or a breach by the Company of any other covenant or
agreement in this Indenture or under the Securities (other than those referred to in Section
6.01(a) through (e) and Section 6.01(g) through (i)) and such default continues for 90 days after
the notice specified below;

(g) default by the Company or any Subsidiary in the payment of the principal or interest on
any mortgage, agreement or other instrument under which there may be outstanding, or by which there
may be secured or evidenced any indebtedness for money borrowed in excess of $25,000,000 in the
aggregate of the Company and/or any such Subsidiary, whether such indebtedness now exists or shall
hereafter be created, resulting in such indebtedness becoming or being declared due and payable,
and such acceleration shall not have been rescinded or annulled within 10 days after written notice
of such acceleration has been received by the Company or such Subsidiary;

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

(i) commences a voluntary case or proceeding;

(ii) consents to the entry of judgment, decree or order for relief against it in an
involuntary case or proceeding;

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

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

(v) consents to or acquiesces in the institution of a bankruptcy or an insolvency
proceeding against it;

(vi) takes any corporate action to authorize or effect any of the foregoing; or

(vii) takes any comparable action under any foreign laws relating to insolvency;

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

(i) is for relief against the Company or any Significant Subsidiary in an involuntary
case;

(ii) appoints a Custodian of the Company for all or substantially all of the
Company’s or any Significant Subsidiary’s property; or

(iii) orders the winding up or liquidation of the Company or Significant Subsidiary;

and, in each case, the order or decree or relief remains unstayed and in effect for 90
days; or

(j) there has been entered in a court of competent jurisdiction a final judgment for the
payment of $25,000,000 or more (excluding any amounts covered by insurance) rendered against the
Company or any Significant Subsidiary, which judgment is not discharged or stayed within 90 days
after (i) the date on which the right to appeal thereof has expired if no such appeal has
commenced, or (ii) the date on which all rights to appeal have been extinguished (“judgment default
provision”).

The foregoing will constitute Events of Default whatever the reason for any such Event of
Default and whether it is voluntary or involuntary or is effected by operation of law or pursuant
to any judgment, decree or order of any court or any order, rule or regulation of any
administrative or governmental body.

Notwithstanding the foregoing, a Default under clause (f) of this Section 6.01 will not
constitute an Event of Default until the Trustee or the Holders of 25% or more in principal amount
of the outstanding Securities notify the Company of the Default in writing and the Company does not
cure such Default within the time specified in clause (f) of this Section 6.01 after receipt of
such notice.

Section 6.02 . Acceleration. If an Event of Default (other than an Event of Default
specified in Section 6.01(h) or 6.01(i) above) occurs and is continuing, the Trustee by notice to
the Company, or the Holders of at least 25% in outstanding principal amount of the outstanding
Securities by notice to the Company and the Trustee, may, and the Trustee at the request of such
Holders shall, declare the principal of and accrued and unpaid interest, if any, and Additional
Interest, if any, on all the Securities to be due and payable. Upon such a declaration, such
principal, premium, if any, and accrued and unpaid interest and Additional Interest, if any, shall
be due and payable immediately. If an Event of Default specified in Section 6.01(h) or 6.01(i)
above occurs and is continuing, the principal of and accrued and unpaid interest, if any, and
Additional Interest, if any, on all the Securities outstanding shall be immediately due and payable
with no further action by the Trustee or the Holders.

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 interest (including any
Additional Interest) on the Securities or to enforce the performance of any provision of the
Securities or this Indenture.

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. No remedy is exclusive
of any other remedy. All available remedies are cumulative.

Section 6.04 . Waiver of Past Defaults. The Holders of a majority in principal amount of the
outstanding Securities by notice to the Trustee may (a) waive, by their consent (including, without
limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer
for, Securities), an existing Default or Event of Default and its consequences except (i) a Default
or Event of Default in the payment of the principal of or interest (including any Additional
Interest) on a Security or (ii) a Default or Event of Default in respect of a provision that under
Section 9.02 cannot be amended without the consent of each Holder affected and (b) rescind any such
acceleration with respect to the Securities and its consequences if (i) rescission would not
conflict with any judgment or decree of a court of competent jurisdiction and (ii) all existing
Events of Default, other than the nonpayment of the principal of and interest (including any
Additional Interest) on the Securities that have become due solely by such declaration of
acceleration, have been cured or waived. When a Default or Event of Default is waived, it is
deemed cured, but no such waiver shall extend to any subsequent or other Default or Event of
Default or impair any consequent right.

Section 6.05 . Control by Majority. The Holders of a majority in principal amount of the
outstanding Securities may direct the time, method and place of conducting any proceeding for any
remedy available to the Trustee or of exercising any trust or power conferred on the Trustee.
However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture
or, subject to Sections 7.01 and 7.02, that the Trustee determines is unduly prejudicial to the
rights of other Holders or would 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.

Section 6.06 . Limitation on Suits. Subject to Section 6.07, a Holder may not pursue any
remedy with respect to this Indenture or the Securities unless:

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

(b) Holders of at least 25% in principal amount of the outstanding Securities have requested
that the Trustee pursue the remedy;

(c) such Holders have offered to the Trustee security or indemnity reasonably satisfactory to
it against any loss, liability or expense to be incurred in compliance with such request;

(d) the Trustee has not complied with such request within 60 days after receipt of the request
and the offer of security or indemnity; and

(e) the Holders of a majority in principal amount of the outstanding Securities have not given
the Trustee a direction that, in the opinion of the Trustee, is inconsistent with such request
within such 60-day period.

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 (including, without limitation, Section 6.06), the right of any Holder to receive
payment of principal of or interest (including any Additional Interest) on the Securities held by
such Holder, on or after the respective due dates expressed in the Securities, or to bring suit for
the enforcement of any such payment on or after such respective dates, shall not be impaired or
affected without the consent of such Holder.

Section 6.08 . Collection Suit by Trustee. If an Event of Default specified in clauses (a)
or (b) of Section 6.01 occurs and is continuing, the Trustee may recover judgment in its own name
and as trustee of an express trust against the Company for the whole amount then due and owing
(together with interest on any unpaid interest (including any Additional Interest) to the extent
lawful) and the amounts provided for in Section 7.07.

Section 6.09 . Trustee May File Proofs of Claim. The Trustee may file such proofs of claim
and other papers or documents as may be necessary or advisable in order to have the claims of the
Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances
of the Trustee, its agents and counsel) and the Holders allowed in any judicial proceedings
relative to the Company, its Subsidiaries or its or their respective creditors or properties and,
unless prohibited by law or applicable regulations, may be entitled and empowered to participate as
a member of any official committee of creditors appointed in such matter, and may vote on behalf of
the Holders in any election of a trustee in bankruptcy or other Person performing similar
functions, and any Custodian in any such judicial proceeding is hereby authorized by each Holder to
make 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 for the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents and its counsel, and
any other amounts due to the Trustee under Section 7.07.

Section 6.10 . Priorities. If the Trustee collects any money or property pursuant to this
Article 6, it shall pay out the money or property 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 for principal and
interest (including any Additional Interest), ratably, without preference or priority of
any kind, according to the amounts due and payable on the Securities for principal and
interest, respectively; and

THIRD: to the Company.

The Trustee may fix a record date and payment date for any payment to Holders pursuant to this
Section 6.10. At least 15 days before such record date, the Company shall mail to each Holder and
the Trustee a notice that states the record date, the payment date and amount to be paid.

Section 6.11 . Restoration of Rights and Remedies. If the Trustee or any Holder has
instituted a proceeding to enforce any right or remedy under this Indenture and the proceeding has
been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or
to the Holder, then, subject to any determination in the proceeding, the Company, the Trustee, any
Subsidiaries and the Holders will be restored severally and respectively to their former positions
hereunder and thereafter all rights and remedies of the Company, the Trustee, any Subsidiaries and
the Holders will continue as though no such proceeding had been instituted.

Section 6.12 . Undertaking of 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
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 and expenses, 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 6.12 does not apply to a suit by the Trustee, a suit by the Company, a suit
by a Holder pursuant to Section 6.07 or a suit by Holders of more than 10% in outstanding principal
amount of the Securities.

ARTICLE 7

Trustee

Section 7.01 . Duties of Trustee. (a) If an Event of Default has occurred and is continuing,
the Trustee shall exercise the rights and powers vested in it by this Indenture and use the same
degree of care and skill in its exercise as a prudent Person would exercise or use under the
circumstances in the conduct of such Person’s own affairs; provided that if an Event of Default
occurs and is continuing, the Trustee will be under no obligation to exercise any of the rights or
powers under this Indenture at the request or direction of any of the Holders unless such Holders
have offered to the Trustee reasonable indemnity or security against loss, liability or expense
that might be incurred in compliance with such request or direction.

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

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

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

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

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

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

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

(d) Every provision of this Indenture that in any way relates to the Trustee is subject to
paragraphs (a), (b) and (c) of this Section 7.01.

(e) 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.

(f) Money held in trust by the Trustee need not be segregated from other funds except to the
extent required by law.

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

(h) Every provision of this Indenture relating to the conduct or affecting the liability of or
affording protection to the Trustee shall be subject to the provisions of this Section 7.01 and to
the provisions of the TIA.

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

Section 7.02 . Rights of Trustee. Subject to Section 7.01:

(a) The Trustee may conclusively rely on any document (whether in its original or facsimile
form) reasonably 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. The Trustee
shall receive and retain financial reports and statements of the Company as provided herein, but
shall have no duty to review or analyze such reports or statements to determine compliance under
covenants or other obligations of the Company.

(b) Before the Trustee acts or refrains from acting, it may require an Officers’ Certificate
and/or an Opinion of Counsel. The Trustee shall not be liable for any action it takes or omits to
take in good faith in reliance on an Officers’ Certificate or Opinion of Counsel.

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

(d) The Trustee shall not be liable for any action it takes or omits to take in good faith
which it believes to be authorized or within its rights or powers, unless the Trustee’s conduct
constitutes willful misconduct or negligence.

(e) The Trustee may consult with counsel of its selection, and the advice or opinion of
counsel with respect to legal matters relating to this Indenture and the Securities shall be full
and complete authorization and protection from liability in respect to any action taken, omitted or
suffered by it hereunder in good faith and in accordance with the advice or opinion of such
counsel.

(f) The Trustee shall not be responsible or liable for special, indirect, or consequential
loss or damage of any kind whatsoever (including, but not limited to, loss of profit) resulting
from actions taken in good faith and which the Trustee believes to be authorized or within its
rights or powers, unless the Trustee’s conduct constitutes willful misconduct or negligence.

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

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

Section 7.03 . Individual Rights of Trustee. The Trustee in its individual or any other
capacity may become the owner or pledgee of Securities and may otherwise deal with the Company or
its Affiliates with the same rights it would have if it were not Trustee. Any Paying Agent,
Registrar, co-registrar or co-paying agent may do the same with like rights. However, the Trustee
must comply with Sections 7.10 and 7.11. In addition, the Trustee shall be permitted to engage in
transactions with the Company; provided, however, that if the Trustee acquires any conflicting
interest the Trustee must (i) eliminate such conflict within 90 days of acquiring such conflicting
interest, (ii) apply to the SEC for permission to continue acting as Trustee or (iii) resign.

Section 7.04 . Trustee’s Disclaimer. The Trustee shall not be responsible for and makes no
representation as to the validity or adequacy of this Indenture or the Securities, shall not be
accountable for the Company’s use of the proceeds from the Securities, shall not be responsible for
the use or application of any money received by any Paying Agent other than the Trustee and shall
not be responsible for any statement of the Company in this Indenture or in any document issued in
connection with the sale of the Securities or in the Securities other than the Trustee’s
certificate of authentication.

Section 7.05 . Notice of Defaults. If a Default or Event of Default occurs and is continuing
and if a Trust Officer of the Trustee has actual knowledge thereof, the Trustee shall mail by first
class mail to each Holder at the address set forth in the Securities Register notice of the Default
or Event of Default within 90 days after it occurs. Except in the case of a Default or Event of
Default in payment of principal of or interest (including any Additional Interest) on any Security
(including payments pursuant to the optional redemption or required repurchase provisions of such
Security, if any), the Trustee may withhold the notice if and so long as its board of directors, a
committee of its board of directors or a committee of its Trust Officers in good faith determines
that withholding the notice is in the interests of Holders.

Section 7.06 . Reports by Trustee to Holders. As promptly as practicable after each May 15
beginning with the May 15 following the date of this Indenture, and in any event prior to July 1 in
each year, the Trustee shall mail to each Holder a brief report dated as of such May 15 that
complies with TIA § 313(a), if required by such TIA § 313(a). The Trustee also shall comply with
TIA § 313(b). The Trustee shall also transmit by mail all reports required by TIA § 313(c).

Section 7.07 . Compensation and Indemnity. The Company shall pay to the Trustee from time to
time such compensation for its acceptance of this Indenture and services hereunder as the Company
and 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. In addition to the
compensation the Company shall reimburse the Trustee upon request for all reasonable out-of-pocket
expenses incurred or made by it. Such expenses shall include the reasonable compensation and
out-of-pocket expenses, disbursements and advances of the Trustee’s agents, counsel, accountants
and experts. The Company shall indemnify the Trustee against any and all loss, liability, damages,
claims or expense (including reasonable attorneys’ fees and expenses) incurred by it without
negligence or bad faith on its part in connection with the administration of this trust and the
performance of its duties hereunder, including the costs and expenses of enforcing this Indenture
(including this Section 7.07) and of defending itself against any claims (whether asserted by any
Holder, the Company or otherwise). The Trustee shall notify the Company promptly of any claim for
which it may seek indemnity. Failure by the Trustee to so notify the Company shall not relieve the
Company of its obligations hereunder. The Company shall defend the claim and the Trustee shall
provide reasonable cooperation at the Company’s expense in the defense. The Trustee may have
separate counsel and the Company shall pay the fees and expenses of such counsel, provided that the
Company shall not be required to pay such fees and expenses if it assumes the Trustee’s defense,
and, in the reasonable judgment of outside counsel to the Trustee, there is no conflict of interest
between the Company and the Trustee in connection with such defense. The Company need not
reimburse any expense or indemnify against any loss, liability or expense incurred by the Trustee
through the Trustee’s own willful misconduct, negligence or bad faith.

To secure the Company’s payment obligations 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 other than
money or property held in trust to pay principal of and interest (including any Additional
Interest) on particular Securities. Such lien shall survive the satisfaction and discharge of this
Indenture. The Trustee’s right to receive payment of any amounts due under this Section 7.07 shall
not be subordinate to any other unsecured liability or debt of the Company.

The Company’s payment obligations pursuant to this Section 7.07 shall survive the discharge of
this Indenture. When the Trustee incurs expenses after the occurrence of a Default specified in
Section 6.01(h) and 6.01(i) with respect to the Company, the expenses are intended to constitute
expenses of administration under any Bankruptcy Law.

Section 7.08 . Replacement of Trustee. The Trustee may resign at any time by so notifying
the Company. The Holders of a majority in principal amount of the Securities may remove the
Trustee by so notifying the Trustee and may appoint a successor Trustee. The Company shall remove
the Trustee if:

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

(b) the Trustee is adjudged bankrupt or insolvent;

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

(d) the Trustee otherwise becomes incapable of acting.

If the Trustee resigns or is removed by the Company or by the Holders of a majority in
principal amount of the Securities and such Holders do not reasonably promptly appoint a successor
Trustee, or if a vacancy exists in the office of the Trustee for any reason (the Trustee in such
event being referred to herein as the retiring Trustee), the Company shall promptly appoint a
successor Trustee.

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

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

If the Trustee fails to comply with Section 7.10, unless the Trustee’s duty to resign is
stayed as provided in TIA § 310(b), any Holder may petition any court of competent jurisdiction for
the removal of the Trustee and the appointment of a successor Trustee.

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

Section 7.09 . Successor Trustee by Merger. If the Trustee consolidates with, merges or
converts into, or transfers all or substantially all its corporate trust business or assets to,
another corporation or banking association, the resulting, surviving or transferee corporation
without any further act shall be the successor Trustee.

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

Section 7.10 . Eligibility; Disqualification. The Trustee shall at all times satisfy the
requirements of TIA § 310(a). The Trustee shall have a combined capital and surplus of at least
$100 million as set forth in its most recent published annual report of condition. The Trustee
shall comply with TIA § 310(b); provided, however, that there shall be excluded from the operation
of TIA § 310(b)(1) any indenture or indentures under which other securities or certificates of
interest or participation in other securities of the Company are outstanding if the requirements
for such exclusion set forth in TIA § 310(b)(1) are met.

Section 7.11 . Preferential Collection of Claims Against Company. The Trustee shall comply
with 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.

ARTICLE 8

Section 8.01 . Discharge of Liability on Securities. When (1) the Company shall deliver to
the Registrar for cancellation all Securities theretofore authenticated (other than any Securities
which have been destroyed, lost or stolen and in lieu of or in substitution for which other
Securities shall have been authenticated and delivered) and not theretofore canceled, or (2) all
the Securities not theretofore canceled or delivered to the Registrar for cancellation shall have
(a) been deposited for conversion (after all related Observation Periods have elapsed) and the
Company shall deliver to the Holders cash and shares of Common Stock, as applicable, sufficient to
pay all amounts owing in respect of all Securities (other than any Securities which shall have been
mutilated, destroyed, lost or stolen and in lieu of or in substitution for which other Securities
shall have been authenticated and delivered) not theretofore canceled or delivered to the Registrar
for cancellation or (b) become due and payable on the Stated Maturity, Purchase Date, Fundamental

Trustee cash and shares of Common Stock, as applicable, sufficient to pay all amounts owing in

authenticated and delivered) not theretofore canceled or delivered to the Registrar for
cancellation, including the principal amount and interest (including any Additional Interest)
accrued and unpaid to such Stated Maturity, Purchase Date, Fundamental Change Purchase Date or
Redemption Date, as the case may be, and if in either case (1) or (2) the Company shall also pay or
cause to be paid all other sums payable hereunder by the Company, then this Indenture with respect
to the Securities shall cease to be of further effect (except as to (i) remaining rights of
registration of transfer, substitution and exchange and conversion of Securities; (ii) rights
hereunder of Holders to receive from the Trustee payments of the amounts then due, including
interest (including any Additional Interest) with respect to the Securities and the other rights,
duties and obligations of Holders, as beneficiaries hereof solely with respect to the amounts, if
any, so deposited with the Trustee; and (iii) the rights, obligations and immunities of the
Trustee, Authenticating Agent, Paying Agent, Conversion Agent and Registrar under this Indenture
with respect to the Securities), and the Trustee, on demand of the Company accompanied by an
Officers’ Certificate and an Opinion of Counsel as required by Section 8.03 and at the cost and
expense of the Company, shall execute proper instruments acknowledging satisfaction of and
discharging this Indenture with respect to the Securities; however, the Company hereby agrees to
reimburse the Trustee, Authenticating Agent, Paying Agent, Conversion Agent and Registrar for any
costs or expenses thereafter reasonably and properly incurred by the Trustee, Authenticating Agent,
Paying Agent, Conversion Agent and Registrar and to compensate the Trustee, Authenticating Agent,
Paying Agent, Conversion Agent and Registrar for any services thereafter reasonably and properly
rendered by the Trustee, Authenticating Agent, Paying Agent, Conversion Agent and Registrar in
connection with this Indenture with respect to the Securities.

Section 8.02 . Reinstatement. If the Trustee or the Paying Agent is unable to apply any
money to the Holders entitled thereto by reason of any order or judgment of any court of
governmental authority enjoining, restraining or otherwise prohibiting such application, the
Company’s obligations under this Indenture with respect to the Securities and the Securities 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 in accordance with
this Indenture and the Securities to the Holders entitled thereto; provided, however, that if the
Company makes any payment of principal amount of or interest (including any Additional Interest) on
any Securities following the reinstatement of its obligations, the Company shall be subrogated to
the rights of the Holders of such Securities to receive such payment from the money held by the
Trustee or Paying Agent.

Section 8.03 . Officers’ Certificate; Opinion of Counsel. Upon any application or demand by
the Company to the Trustee to take any action under Section 8.01, the Company shall furnish to the
Trustee an Officers’ Certificate or Opinion of Counsel stating that all conditions precedent, if
any, provided for in this Indenture relating to the proposed action have been complied with.

ARTICLE 9

Amendments

Section 9.01 . Without Consent of Holders. The Company, and the Trustee may amend this
Indenture or the Securities without notice to or consent of any Holder:

(a) to cure any ambiguity, omission, defect or inconsistency;

(b) to comply with Article 4 in respect of the assumption by a Successor Company of an
obligation of the Company under this Indenture;

(c) to provide for uncertificated Securities in addition to or in place of certificated
Securities; provided, however, that the uncertificated Securities are issued in registered form for
purposes of Section 163(f) of the Code or in a manner such that the uncertificated Securities are
described in Section 163(f)(2)(B) of the Code;

(d) to add guarantees with respect to the Securities;

(e) to secure the Securities;

(f) to add to the covenants of the Company for the benefit of the Holders or to surrender any
right or power herein conferred upon the Company;

(g) to comply with any requirement of the SEC in connection with the qualification of this
Indenture under the TIA;

(h) to make any change that does not materially adversely affect the rights of any Holder; or

(i) to conform the provisions of this Indenture to the “Description of Notes” section of the
Offering Memorandum.

After an amendment under this Section 9.01 becomes effective, the Company shall mail to
Holders a notice briefly describing such amendment. The failure to give such notice to all
Holders, or any defect therein, shall not impair or affect the validity of an amendment under this
Section 9.01.

Section 9.02 . With Consent of Holders. The Company, and the Trustee may amend this
Indenture or the Securities without notice to any Holder but with the written or electronic consent
of the Holders of at least a majority in principal amount of the Securities then outstanding
(including, without limitation, consents obtained in connection with a purchase of, or tender offer
or exchange offer for, Securities) and past Defaults or compliance with the provisions of this
Indenture may be waived with the written consent of the Holders of at least a majority in principal
amount of the Securities then outstanding (including, without limitation, consents obtained in
connection with a purchase of, or tender offer or exchange offer for, Securities). However,
without the consent of each Holder affected, an amendment or waiver may not:

(a) reduce the amount of Securities whose Holders must consent to an amendment;

(b) reduce the rate of or extend the stated time for payment of interest, including Additional
Interest, on any Security;

(c) reduce the principal of or extend the Stated Maturity of any Security;

(d) make any change that adversely affects the conversion rights of any Securities;

(e) reduce the Redemption Price, the Fundamental Change Purchase Price, the Purchase Price
payable upon the redemption or repurchase or conversion of any Security or amend or modify in any
manner adverse to holders of the Securities the Company’s obligation to make such payments, whether
through an amendment to or waiver of a provision in the covenants, definitions or otherwise;

(f) make any Security payable in money other than that stated in the Security (it being
understood that all references to cash in this Indenture and the Securities are to U.S. legal
tender);

(g) impair the right of any Holder to receive payment of principal of and interest (including
any Additional Interest) on such Holder’s Securities on or after the due dates therefor or to
institute suit for the enforcement of any payment on or with respect to such Holder’s Securities;
or

(h) make any change to the amendment provisions which require each Holder’s consent or to the
waiver provisions.

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 or waiver, but it shall be sufficient if such consent
approves the substance thereof. A consent to any amendment or waiver under this Indenture by any
Holder of the Securities given in connection with a tender or exchange of such Holder’s Securities
will not be rendered invalid by such tender or exchange.

After an amendment under this Section 9.02 becomes effective, the Company shall mail to
Holders a notice briefly describing such amendment. The failure to give such notice to all
Holders, or any defect therein, shall not impair or affect the validity of an amendment under this
Section 9.02.

Section 9.03 . Compliance with Trust Indenture Act. Every amendment or supplement to this
Indenture or the Securities shall comply with the TIA as then in effect.

Section 9.04 . Revocation and Effect of Consents and Waivers. A consent to an amendment or a
waiver by a Holder of a Security shall bind the Holder and every subsequent Holder of that Security
or portion of the Security that evidences the same debt as the consenting Holder’s Security, even
if notation of the consent or waiver is not made on the Security. However, any such Holder or
subsequent Holder may revoke the consent or waiver as to such Holder’s Security or portion of the
Security if the Trustee receives the notice of revocation before the date the amendment or waiver
becomes effective or otherwise in accordance with any related solicitation documents. After an
amendment or waiver becomes effective, it shall bind every Holder. An amendment or waiver shall
become effective upon receipt by the Trustee of the requisite number of written consents under
Section 9.01 or 9.02, as applicable.

The Company may, but shall not be obligated to, fix a record date for the purpose of
determining the Holders entitled to give their consent or take any other action described above or
required or permitted to be taken pursuant to this Indenture. If a record date is fixed, then
notwithstanding 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 give such
consent or to revoke any consent previously given or to take any such action, whether or not such
Persons continue to be Holders after such record date. No such consent shall become valid or
effective more than 120 days after such record date.

Section 9.05 . Notation on or Exchange of Securities. If an amendment changes the terms of a
Security, the Trustee may require the Holder of the Security to deliver it to the Trustee. The
Trustee may place an appropriate notation on the Security regarding the changed terms and return it
to the Holder. Alternatively, if the Company or the Trustee 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.

Section 9.06 . Trustee to Sign Amendments. The Trustee shall sign any amendment authorized
pursuant to this Article 9 if the amendment 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 such amendment the Trustee shall be entitled to receive and (subject to Sections 7.01 and
7.02) shall be fully protected in relying upon, an Officers’ Certificate and an Opinion of Counsel
stating that such amendment is authorized or permitted by this Indenture.

ARTICLE 11

Purchase at the Option of Holder Upon a Fundamental

Change; Purchase at the Option of Holders

Section 11.01 . Purchase at the Option of the Holder Upon a Fundamental Change. If a
Fundamental Change shall occur at any time, each Holder shall have the right, at such Holder’s
option, to require the Company to purchase any or all of such Holder’s Securities on a date
specified by the Company that is no later than 35 calendar days after the date of the Company
Notice of the occurrence of such Fundamental Change (subject to extension to comply with applicable
law, as provided in Section 11.03(d)) (the “Fundamental Change Purchase Date”). The Securities
shall be repurchased in multiples of $1,000 of the principal amount. The Company shall purchase
such Securities at a price (the “Fundamental Change Purchase Price”), which shall be paid in cash,
equal to 100% of the principal amount of the Securities to be purchased plus accrued and unpaid
interest, including any Additional Interest, to but excluding the Fundamental Change Purchase Date,
unless the Fundamental Change Purchase Date is between a Regular Record Date and the interest
payment date to which it relates, in which case the Fundamental Change Purchase Price shall equal
100% of the principal amount of Securities to be purchased and accrued and unpaid interest,
including Additional Interest, shall be paid to the Holder of record on the Regular Record Date.

(a) Notice of Fundamental Change. The Company, or at its request (which must be received by
the Paying Agent at least three Business Days (or such lesser period as agreed to by the Paying
Agent) prior to the date the Paying Agent is requested to give such notice as described below) the
Paying Agent, in the name of and at the expense of the Company, shall mail to all Holders and the
Trustee a Company Notice of the occurrence of a Fundamental Change and of the purchase right
arising as a result thereof, including the information required by Section 11.03(a) hereof, on or
before the 20th calendar day after the occurrence of such Fundamental Change. The
Company shall promptly furnish to the Paying Agent a copy of such Company Notice.

(b) Exercise of Option. For a Security to be so purchased at the option of the Holder, the
Paying Agent must receive such Security duly endorsed for transfer, together with a written notice
of purchase (a “Fundamental Change Purchase Notice”) in the form entitled “Form of Fundamental
Change Purchase Notice” attached to the Security duly completed, on or before the Business Day
immediately preceding the Fundamental Change Purchase Date, subject to extension to comply with
applicable law. The Fundamental Change Purchase Notice shall state:

(i) if certificated, the certificate numbers of the Securities which the Holder shall
deliver to be purchased;

(ii) the portion of the principal amount of the Securities which the Holder shall
deliver to be purchased, which portion must be $1,000 in principal amount or a multiple
thereof; and

(iii) that such Securities shall be purchased as of the Fundamental Change Purchase
Date pursuant to the terms and conditions specified in paragraph 6 of the Securities and
in this Indenture.

(c) Procedures. The Company shall purchase from a Holder, pursuant to this Section 11.01,
Securities if the principal amount of such Securities is $1,000 or a multiple of $1,000 if so
requested by such Holder.

Any purchase by the Company contemplated pursuant to the provisions of this Section 11.01
shall be consummated by the delivery of the Fundamental Change Purchase Price to be received by the
Holder promptly following the later of the Fundamental Change Purchase Date or the time of
book-entry transfer or delivery of the Securities.

Notwithstanding anything herein to the contrary, any Holder delivering to the Paying Agent the
Fundamental Change Purchase Notice contemplated by this Section 11.01 shall have the right at any
time prior to the close of business on the Business Day prior to the Fundamental Change Purchase
Date to withdraw such Fundamental Change Purchase Notice (in whole or in part) by delivery of a
written notice of withdrawal to the Paying Agent in accordance with Section 11.03(b).

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

On or before 11:00 a.m. (New York City time) on the Fundamental Change Purchase Date, the
Company shall deposit with the Paying Agent (or if the Company or an Affiliate of the Company is
acting as the Paying Agent, shall segregate and hold in trust) cash sufficient to pay the aggregate
Fundamental Change Purchase Price of the Securities to be purchased pursuant to this Section 11.01.
Payment by the Paying Agent of the Fundamental Change Purchase Price for such Securities shall be
made promptly following the later of the Fundamental Change Purchase Date or the time of book-entry
transfer or delivery of such Securities. If the Paying Agent holds, in accordance with the terms
of this Indenture, cash sufficient to pay the Fundamental Change Purchase Price of such Securities
on the Fundamental Change Purchase Date, then, on and after such date, such Securities shall cease
to be outstanding and interest (including any Additional Interest), on such Securities shall cease
to accrue, whether or not book-entry transfer of such Securities is made or such Securities are
delivered to the Paying Agent, and all other rights of the Holder shall terminate (other than the
right to receive the Fundamental Change Purchase Price and previously accrued and unpaid interest
(including any Additional Interest), upon delivery or transfer of the Securities). Nothing herein
shall preclude any withholding tax required by law.

The Company shall require each Paying Agent (other than the Trustee) to agree in writing that
the Paying Agent shall hold in trust for the benefit of Holders or the Trustee all cash held by the
Paying Agent for the payment of the Fundamental Change Purchase Price and shall notify the Trustee
of any default by the Company in making any such payment. If the Company or an Affiliate of the
Company acts as Paying Agent, it shall segregate the cash held by it as Paying Agent and hold it as
a separate trust fund. The Company at any time may require a Paying Agent to deliver all cash held
by it to the Trustee and to account for any funds disbursed by the Paying Agent. Upon doing so, the
Paying Agent shall have no further liability for the cash delivered to the Trustee.

Section 11.02 . Purchase of Securities at the Option of the Holder.

(a) A Holder shall have the option to require the Company to purchase any outstanding
Securities on each of June 15, 2016 and June 15, 2026 (each, a “Purchase Date”), at a price (the
“Purchase Price”) which shall be paid in cash, equal to 100% of the principal amount of the
Securities to be repurchased plus any accrued and unpaid interest, including any Additional
Interest, to but excluding the Purchase Date, upon:

(i) delivery to the Paying Agent by the Holder of a written notice of purchase (a
“Purchase Notice”) at any time from the opening of business on the date that is 20
Business Days prior to a Purchase Date until the close of business on the Business Day
prior to such Purchase Date, stating:

(A) if certificated, the certificate numbers of the Securities which the
Holder will deliver to be purchased, or, if not certificated, the Purchase
Notice must comply with appropriate DTC procedures;

(B) the portion of the principal amount of the Securities which the Holder
will deliver to be purchased, which portion must be $1,000 in principal amount
or a multiple thereof;

(C) that such Securities shall be purchased as of the Purchase Date
pursuant to the terms and conditions specified in paragraph 6 of the Securities
and in this Indenture; and

(ii) delivery or book-entry transfer of such Securities to the Paying Agent (together
with all necessary endorsements) at the offices of the Paying Agent, such delivery or
transfer being a condition to receipt by the Holder of the Purchase Price therefor;
provided, however, that such Purchase Price shall be so paid pursuant to this Section
11.02 only if the Securities so delivered or transferred to the Paying Agent shall conform
in all respects to the description thereof in the related Purchase Notice.

(b) The Company shall purchase from a Holder, pursuant to this Section 11.02, Securities if
the principal amount of such Securities is $1,000 or a multiple of $1,000 if so requested by such
Holder.

(c) Any purchase by the Company contemplated pursuant to the provisions of this Section 11.02
shall be consummated by the delivery of the Purchase Price to be received by the Holder promptly
following the later of the Purchase Date or the time of book-entry transfer or delivery of the
Securities.

(d) Notwithstanding anything herein to the contrary, any Holder delivering to the Paying Agent
the Purchase Notice contemplated by this Section 11.02 shall have the right at any time prior to
the close of business on the Business Day prior to the Purchase Date to withdraw such Purchase
Notice (in whole or in part) by delivery of a written notice of withdrawal to the Paying Agent in
accordance with Section 11.03(b).

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

(f) On or before 11:00 a.m. (New York City time) on the Purchase Date, the Company shall
deposit with the Paying Agent (or if the Company or an Affiliate of the Company is acting as the
Paying Agent, shall segregate and hold in trust) cash sufficient to pay the aggregate Purchase
Price of the Securities to be purchased pursuant to this Section 11.02. Payment by the Paying
Agent of the Purchase Price for such Securities shall be made promptly following the later of the
Purchase Date or the time of book-entry transfer or delivery of such Securities. If the Paying
Agent holds, in accordance with the terms of this Indenture, cash sufficient to pay the Purchase
Price of such Securities on the Purchase Date, then, on and after such date, such Securities shall
cease to be outstanding and interest (including any Additional Interest) on such Securities shall
cease to accrue, whether or not book-entry transfer of such Securities is made or such Securities
are delivered to the Paying Agent, and all other rights of the Holder shall terminate (other than
the right to receive the Purchase Price and previously accrued interest (including any Additional
Interest) upon delivery or transfer of the Securities). Nothing herein shall preclude any
withholding tax required by law.

(g) The Company shall require each Paying Agent (other than the Trustee) to agree in writing
that the Paying Agent shall hold in trust for the benefit of Holders or the Trustee all cash held
by the Paying Agent for the payment of the Purchase Price and shall notify the Trustee of any
default by the Company in making any such payment. If the Company or an Affiliate of the Company
acts as Paying Agent, it shall segregate the cash held by it as Paying Agent and hold it as a
separate trust fund. The Company at any time may require a Paying Agent to deliver all cash held by
it to the Trustee and to account for any funds disbursed by the Paying Agent. Upon doing so, the
Paying Agent shall have no further liability for the cash delivered to the Trustee.

Section 11.03 . Further Conditions and Procedures for Purchase at the Option of the Holder
Upon a Fundamental Change and Purchase of Securities at the Option of the Holder.

(a) Notice of Purchase Date or Fundamental Change. The Company shall send notices (each, a
“Company Notice”) to the Holders at their addresses shown in the Securities Register maintained by
the Registrar, and delivered to the Trustee and Paying Agent, not less than 20 Business Days prior
to each Purchase Date, or on or before the 20th calendar day after the occurrence of the
Fundamental Change, as the case may be (each such date of delivery, a “Company Notice Date”). Each
Company Notice shall include a form of Purchase Notice or Fundamental Change Purchase Notice to be
completed by a Holder and shall state:

(i) the applicable Purchase Price or Fundamental Change Purchase Price;

(ii) Conversion Rate at the time of such notice and any expected adjustments to the
Conversion Rate;

Indenture;

as to which a Purchase Notice or a Fundamental Change Purchase Notice, as applicable, has

later of the Purchase Date or Fundamental Change Purchase Date, as applicable, or the time
of book-entry transfer or delivery of such Securities;

(viii) the procedures the Holder must follow under Sections 11.01 or 11.02, as
applicable, and Section 11.03;

(ix) briefly, the conversion rights of the Securities;

(x) that, unless the Company defaults in making payment of such Purchase Price or

Purchase Date, as applicable;

(xi) the CUSIP or ISIN number of the Securities;

(xii) the procedures for withdrawing a Purchase Notice or Fundamental Change Purchase

Simultaneously with providing such Company Notice, the Company will publish a notice
containing the information in such Company Notice in a newspaper of general circulation in The City
of New York or publish such information on its then existing website or through such other public
medium as it may use at the time.

At the Company’s request, made at least five Business Days prior to the date upon which such
notice is to be mailed, and at the Company’s expense, the Paying Agent shall give the Company
Notice in the Company’s name; provided, however, that, in all cases, the text of the Company Notice
shall be prepared by the Company.

(b) Effect of Purchase Notice or Fundamental Change Purchase Notice; Withdrawal; Effect of
Event of Default. Upon receipt by the Company of the Purchase Notice or Fundamental Change
Purchase Notice specified in Section 11.02(a) or Section 11.01(b), as applicable, the Holder of the
Securities in respect of which such Purchase Notice or Fundamental Change Purchase Notice, as the
case may be, was given shall (unless such Purchase Notice or Fundamental Change Purchase Notice is
withdrawn as specified in the following two paragraphs) thereafter be entitled to receive solely
the Purchase Price or Fundamental Change Purchase Price with respect to such Securities. Such
Purchase Price or Fundamental Change Purchase Price shall be paid by the Paying Agent to such
Holder promptly following the later of (x) the Purchase Date or the Fundamental Change Purchase
Date, as the case may be, with respect to such Securities (provided the conditions in this Article
11 have been satisfied) and (y) the time of delivery or book-entry transfer of such Securities to
the Paying Agent by the Holder thereof in the manner required by Section 11.02 or Section 11.01, as
applicable. Securities in respect of which a Purchase Notice or Fundamental Change Purchase Notice,
as the case may be, has been given by the Holder thereof may not be converted on or after the date
of the delivery of such Purchase Notice or Fundamental Change Purchase Notice, as the case may be,
unless such Purchase Notice or Fundamental Change Purchase Notice, as the case may be, has first
been validly withdrawn as specified in the following two paragraphs.

A Purchase Notice or Fundamental Change Purchase Notice, as the case may be, may be withdrawn
by means of a written notice of withdrawal delivered to the office of the Paying Agent at any time

Fundamental Change Purchase Date, as the case may be, to which it relates, specifying:

(i) the principal amount of the Securities with respect to which such notice of
withdrawal is being submitted;

(ii) if certificated, the certificate number of the Securities in respect of which
such notice of withdrawal is being submitted, or, if not certificated, the written notice
of withdrawal must comply with appropriate DTC procedures; and

(iii) the principal amount, if any, of such Securities which remains subject to the
original Purchase Notice or Fundamental Change Purchase Notice, as the case may be, and
which has been or shall be delivered for purchase by the Company.

There shall be no purchase of any Securities pursuant to Section 11.02 or Section 11.01 if an
Event of Default has occurred and is continuing (other than a default that is cured by the payment
of the Purchase Price or Fundamental Change Purchase Price, as the case may be). The Paying Agent
shall promptly return to the respective Holders thereof any Securities (x) with respect to which a
Purchase Notice or Fundamental Change Purchase Notice, as the case may be, has been withdrawn in
compliance with this Indenture, or (y) held by it during the continuance of an Event of Default
(other than a default that is cured by the payment of the Purchase Price or Fundamental Change
Purchase Price, as the case may be) in which case, upon such return, the Purchase Notice or
Fundamental Change Purchase Notice with respect thereto shall be deemed to have been withdrawn.

(c) Securities Purchased in Part. Any Securities that are to be purchased only in part shall
be surrendered at the office of the Paying Agent (with, if the Company or the Trustee so requires,
due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the
Trustee duly executed by, the Holder thereof or such Holder’s attorney duly authorized in writing)
and the Company shall execute and the Trustee or the Authenticating Agent shall authenticate and
deliver to the Holder of such Securities, without service charge, a new Security or Securities, of
any authorized denomination as requested by such Holder in aggregate principal amount equal to, and
in exchange for, the portion of the principal amount of the Securities so surrendered which is not
purchased or redeemed.

(d) Covenant to Comply with Securities Laws Upon Purchase of Securities. In connection with
any offer to purchase Securities under Section 11.02 or Section 11.01, the Company shall, to the
extent applicable, (a) comply with Rules 13e-4 and 14e-1 (and any successor provisions thereto)
under the Exchange Act, if applicable; (b) file the related Schedule TO (or any successor schedule,
form or report) under the Exchange Act, if applicable; and (c) otherwise comply with all applicable
federal and state securities laws so as to permit the rights and obligations under Section 11.02 or
Section 11.01 to be exercised in the time and in the manner specified in Section 11.02 or Section
11.01.

(e) Repayment to the Company. The Trustee and the Paying Agent shall return to the Company
any cash or property that remains unclaimed, as provided in paragraph 8 of the Securities, together
with interest that the Trustee or Paying Agent, as the case may be, has expressly agreed in writing
to pay, if any, that is held by them for the payment of a Purchase Price or Fundamental Change
Purchase Price, as the case may be; provided, however, that to the extent that the aggregate amount
of cash or property deposited by the Company pursuant to Section 11.01(c) or Section 11.02(f), as
applicable, exceeds the aggregate Purchase Price or Fundamental Change Purchase Price, as the case
may be, of the Securities or portions thereof which the Company is obligated to purchase as of the
Purchase Date or Fundamental Change Purchase Date, as the case may be, then promptly on and after
the Business Day following the Purchase Date or Fundamental Change Purchase Date, as the case may
be, the Trustee and the Paying Agent shall return any such excess to the Company together with
interest that the Trustee or Paying Agent, as the case may be, has expressly agreed in writing to
pay, if any.

(f) Officers’ Certificate. At least five Business Days before the Company Notice Date, the
Company shall deliver an Officers’ Certificate to the Trustee specifying whether the Company
desires the Trustee to give the Company Notice required by Section 11.03(a) herein.

ARTICLE 12

Conversion

Section 12.01 . Conversion of Securities. (a) Right to Convert. Subject to the procedures
for conversion set forth in this Article 12, a Holder may convert its Securities on or prior to the
close of business on the Business Day immediately preceding Stated Maturity at the Conversion Rate
when any of the conditions specified below are met and during the related specified period.
Whenever the Securities shall become convertible upon one or more of the conditions stated in
clauses (i), (ii) or (iv)(A) below, the Company or, at the Company’s request, the Trustee in the
name and at the expense of the Company, shall notify the Holders of the event triggering such
convertibility in the manner provided in Section 13.02 and the Company shall also publicly announce
such information by publication on the Company’s website or through such other public medium as it
may use at such time. Whenever the Securities shall become convertible upon one or more of the
conditions stated in clauses (iii), (iv)(B) or (iv)(C), notice of the event triggering such
convertibility shall be given in accordance with the provisions of Section 5.04 or 11.01(a) and
11.03, as applicable. Any notice so given shall be conclusively presumed to have been duly given,
whether or not the Holder receives such notice.

(i) Conversion Upon Satisfaction of Sale Price Condition. A Holder may surrender all
or a portion of its Securities for conversion during any fiscal quarter (and only during
such fiscal quarter) commencing after September 30, 2006 if the Last Reported Sale Price
for 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 immediately preceding fiscal quarter is
greater than or equal to 130% of the Conversion Price in effect on such last Trading Day.

(ii) Conversion Upon Satisfaction of Trading Price Condition. Prior to May 15, 2016,
a Holder may surrender its Securities for conversion during the five Business Day period
after any 10 consecutive Trading Day period (the “Measurement Period”) in which the
Trading price per $1,000 principal amount of Securities, as determined following a request
by a Holder in accordance with the procedures set forth in this Section 12.01(a)(ii), for
each day of that period was less than 98% of the product of the Last Reported Sale Price
of the Common Stock and the applicable Conversion Rate. In connection with any conversion
in accordance with this Section 12.01(a)(ii), the Bid Solicitation Agent shall have no
obligation to determine the Trading Price of the Securities unless requested by the
Company; and the Company shall have no obligation to make such request unless a Holder
provides the Company with reasonable evidence that the Trading Price per $1,000 principal
amount of Securities would be less than 98% of the product of the Last Reported Sale Price
of the Common Stock and the applicable Conversion Rate. Promptly after receiving such
evidence, the Company shall instruct the Bid Solicitation Agent to determine the Trading
Price of the Securities beginning on the next Trading Day and on each successive Trading
Day until the Trading Price per $1,000 principal amount of Securities is greater than or
equal to 98% of the product of the Last Reported Sale Price of the Common Stock and the
applicable Conversion Rate.

(iii) Conversion Upon Notice of Redemption. A Holder may surrender for conversion
all or a portion of its Securities called for redemption at any time prior to the close of
business on the third Scheduled Trading Day prior to the related Redemption Date. For the
avoidance of doubt, if the Company gives two or more notices of redemption such that the
Observation Periods applicable to the relevant Redemption Dates overlap, the Observation
Period related to the notice of redemption immediately preceding the time such Securities
are surrendered for conversion shall be applicable to such Securities.

(iv) Conversion Upon Specified Corporate Transactions.

(A) If the Company (1) issues to all or substantially all holders of Common
Stock rights entitling them to purchase, for a period expiring within 60 days
after the date of the distribution, shares of Common Stock at less than the
average of the Last Reported Sale Price of a share of Common Stock for the 10
consecutive Trading Day period ending on the Business Day preceding the
commencement of such issuance, or (2) distributes to all or substantially all
holders of Common Stock assets, debt securities or rights to purchase securities
of the Company, which distribution has a per share Fair Market Value, as
reasonably determined by the Company’s Board of Directors, exceeding 10% of the
Last Reported Sale Price of the Common Stock on the day preceding the
declaration date for such distribution, then, in each case, the Company must
notify the Holders, in the manner provided in Section 13.02, at least 35
Scheduled Trading Days prior to the Ex-Dividend Date for such distribution. Once
the Company has given such notice, Holders may surrender Securities for
conversion at any time until the earlier of 5:00 p.m., New York City time, on
the Business Day immediately prior to such Ex-Dividend Date or the Company’s
announcement that such distribution will not take place.

(B) If the Company is party to a transaction described in clause (2) of the
definition of Fundamental Change (without, for the avoidance of doubt, giving
effect to the proviso set forth in the definition thereof relating to Publicly
Traded Securities), the Company must notify Holders, in the manner provided in
Section 13.02, at least 35 Scheduled Trading Days prior to the anticipated
effective date for such transaction. Once the Company has given such notice,
Holders may surrender Securities for conversion at any time until 35 calendar
days after the actual effective date of such transaction (or if such transaction
also constitutes a Fundamental Change, the related Fundamental Change Purchase
Date).

(C) If a Fundamental Change of the type described in clause (1) or (5) in
the definition thereof occurs, Holders may surrender Securities for conversion
at any time beginning on the actual effective date of such Fundamental Change
until and including the date which is 30 calendar days after the actual
effective date of such transaction or, if later, until the related Fundamental
Change Purchase Date.

A Holder may convert a portion of the principal amount of Securities if the portion is $1,000 or a
multiple of $1,000. The cash payable, and the number of shares of Common Stock issuable, if any,
upon conversion of a Security shall be determined as set forth in Section 12.01(c).

(b) Conversion Procedures. The following procedures shall apply to the conversion of
Securities:

(i) In respect of a Definitive Security, a Holder must (A) complete and manually sign
the conversion notice attached to the Security, or facsimile of such conversion notice;
(B) deliver such conversion notice, which is irrevocable, and the Security to the
Conversion Agent at the office maintained by the Conversion Agent for such purpose; (C) to
the extent any shares of Common Stock issuable upon conversion are to be issued in a name
other than the Holder’s, furnish endorsements and transfer documents as may be required by
the Conversion Agent and, if required pursuant to Section 12.01(e) below, pay all transfer
or similar taxes; and (D) if required pursuant to Section 2.01(d) above, pay funds equal
to interest payable on the next interest payment date to which such Holder is not
entitled.

(ii) In respect of a beneficial interest in a Global Security, a Beneficial Owner
must comply with DTC’s procedures for converting a beneficial interest in a Global
Security and, if required pursuant to Section 2.01(d) above, pay funds equal to interest
payable on the next interest payment date to which such Beneficial Owner is not entitled,
and if required, taxes or duties, if any.

The date a Holder satisfies the foregoing requirements is the “Conversion Date” hereunder.

If a Holder converts more than one Security at the same time, the cash and number of shares of
Common Stock issuable upon the conversion, if any, shall be based on the total principal amount of
the Securities converted.

Upon surrender of a Security that is converted in part, the Company shall execute, and the
Trustee or the Authenticating Agent shall authenticate and deliver to the Holder, a new Security in
an authorized denomination equal in principal amount to the unconverted portion of the Security
surrendered.

(c) Payment Upon Conversion. Upon any conversion of any Security, the Company will deliver to
converting Holders, in respect of each $1,000 principal amount of Securities being converted, a
“Settlement Amount” equal to the sum of the Daily Settlement Amounts for each of the 25 Trading
Days during the Observation Period for such Security.

“Daily Settlement Amount,” for each of the 25 Trading Days during the Observation Period,
shall consist of:

(i) cash equal to the lesser of $40 and the Daily Conversion Value; and

(ii) to the extent the Daily Conversion Value exceeds $40, a number of shares equal
to (A) the difference between the Daily Conversion Value and $40, divided by (B) the Daily
VWAP for such day.

“Daily Conversion Value” means, for each of the 25 consecutive Trading Days during the
Observation Period, 4% of the product of (1) the applicable Conversion Rate and (2) the Daily VWAP
of the Common Stock on such day.

“Daily VWAP” means, for each of the 25 consecutive Trading Days during the Observation Period,
the per share volume-weighted average price as displayed under the heading “Bloomberg VWAP” on
Bloomberg page “GPI.N<equity> AQR”, or any successor page, in respect of the period from 9:30
a.m. to 4:00 p.m., New York City time, on such Trading Day (or if such volume-weighted average
price is unavailable, the market value of one share of Common Stock on such Trading Day as
determined using a volume-weighted average method by a nationally recognized independent investment
banking firm retained for the purpose by the Company).

The Settlement Amount in respect of any Security converted will be delivered to converting
Holders on the third Business Day immediately following the last day of the Observation Period for
such Security.

(d) Cash Payments in Lieu of Fractional Shares. The Company shall not issue a fractional share
of Common Stock upon conversion of Securities. Instead the Company shall deliver cash for the
current market value of the fractional share. The current market value of a fractional share shall
be determined to the nearest 1/10,000th of a share by multiplying the Daily VWAP of a full share of
Common Stock on the final Trading Day of the related Observation Period by the fractional amount
and rounding the product to the nearest whole cent.

(e) Taxes on Conversion. If a Holder converts Securities, the Company shall pay any
documentary, stamp or similar issue or transfer tax due on the issue of shares of Common Stock upon
the conversion. However, the Holder shall pay any such tax which is due because the Holder requests
the shares to be issued in a name other than the Holder’s name. The Conversion Agent may refuse to
deliver the certificates representing the Common Stock being issued in a name other than the
Holder’s name until the Conversion Agent receives a sum sufficient to pay any tax which shall be
due because the shares are to be issued in a name other than the Holder’s name, but the Conversion
Agent shall have no duty to determine if any such tax is due. Nothing herein shall preclude any
withholding of tax required by law.

(f) Certain Covenants of the Company.

(i) The Company shall, prior to issuance of any Securities hereunder, and from time
to time as may be necessary, reserve out of its authorized but unissued Common Stock or
 shares of Common Stock held in treasury, a sufficient number of shares of Common Stock,
free of preemptive rights, to permit the conversion of the Securities.

(ii) All shares of Common Stock delivered upon conversion of the Securities shall be
newly issued shares or treasury shares, shall be duly and validly issued and fully paid
and nonassessable and shall be free from preemptive rights and free of any lien or adverse
claim.

(iii) The Company shall endeavor promptly to comply with all federal and state
securities laws regulating the issuance and delivery of shares of Common Stock upon the
conversion of Securities, if any, and shall cause to have listed or quoted all such shares
of Common Stock on each U.S. national securities exchange or over-the-counter or other
domestic market on which the Common Stock is then listed or quoted.

(iv) Before taking any action which would cause an adjustment increasing the
Conversion Rate to an amount that would cause the Conversion Price to be reduced below the
then par value per share the Common Stock, if any, of the shares of Common Stock issuable
upon conversion of the Securities, the Company will take all corporate action which may,
in the opinion of its counsel, be necessary in order that the Company may validly and
legally issue shares of such Common Stock at such adjusted Conversion Rate.

Section 12.02 . Adjustments to Conversion Rate. The Conversion Rate shall be adjusted from
time to time by the Company as follows:

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

	 	 	 	 	 
	where,

	 	

	 	

	 
	 	 	 	 
	CR0

	 	=
	 	the Conversion Rate in effect immediately prior to such

event
	 
	 	 	 	 
	CR’

	 	=
	 	the Conversion Rate in effect immediately after such event
	 
	 	 	 	 
	OS0

	 	=
	 	the number of shares of Common Stock outstanding

immediately prior to such event
	 
	 	 	 	 
	OS’

	 	=
	 	the number of shares of Common Stock outstanding

immediately after such event.

Such adjustment shall become effective immediately after 9:00 a.m., New York City time, on the
Business Day following the Record Date for such dividend or distribution, or the date fixed for
determination for such share split or share combination. If any dividend or distribution of the
type described in this Section 12.02(a) is declared but not so paid or made, the Conversion Rate
shall again be adjusted to the Conversion Rate that would then be in effect if such dividend or
distribution had not been declared.

(b) If the Company issues to all or substantially all holders of its Common Stock any rights
or warrants entitling them for a period of not more than 60 calendar days to subscribe for or
purchase shares of Common Stock at a price per share less than the average of the Last Reported
Sale Prices of the Common Stock for the 10 consecutive Trading Day period ending on the Business
Day immediately preceding the date of announcement of such issuance, the Conversion Rate will be
adjusted based on the following formula (provided that the Conversion Rate will be readjusted to
the extent that such rights or warrants are not exercised prior to their expiration):

	 	 	 	 	 
	where,

	 	

	 	

	 
	 	 	 	 
	CR0

	 	=
	 	the Conversion Rate in effect immediately prior to such

event
	 
	 	 	 	 
	CR’

	 	=
	 	the Conversion Rate in effect immediately after such event
	 
	 	 	 	 
	OS0

	 	=
	 	the number of shares of Common Stock outstanding

immediately prior to such event
	 
	 	 	 	 
	X

	 	=
	 	the total number of shares of Common Stock issuable

pursuant to such rights
	 
	 	 	 	 
	Y

	 	=
	 	the number of shares of Common Stock equal to the

aggregate price payable to exercise such rights divided

by the average of the Last Reported Sale Prices of the

Common Stock over the 10 consecutive Trading Day period

ending on the Business Day immediately preceding the date

of announcement of the issuance of such rights.

Such adjustment shall be successively made whenever any such rights or warrants are issued and
shall become effective immediately after 9:00 a.m., New York City time, on the Business Day
following the date fixed for determination of Holders entitled to receive such rights or warrants.
To the extent that shares of Common Stock are not delivered after the expiration of such rights or
warrants, the Conversion Rate shall be readjusted to the 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 Conversion Rate shall again be adjusted to be the Conversion Rate
that would then be in effect if such date fixed for the determination of stockholders entitled to
receive such rights or warrants had not been fixed.

In determining whether any rights or warrants entitle the holders to subscribe for or purchase
shares of Common Stock at less than such Last Reported Sale Price, and in determining the aggregate
offering price of such shares of Common Stock, there shall be taken into account any consideration
received by the Company for such rights or warrants and any amount payable on exercise or
conversion thereof, the value of such consideration, if other than cash, to be determined by the
Board of Directors.

(c) If the Company distributes shares of Capital Stock, evidences of its indebtedness or other
assets or property of the Company to all or substantially all holders of the Common Stock,
excluding:

(i) dividends or distributions and rights or warrants referred to in clause (a) or
(b) above; and

(ii) dividends or distributions paid exclusively in cash;

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

	 	 	 	 	 
	where,

	 	

	 	

	 
	 	 	 	 
	CR0

	 	=
	 	the Conversion Rate in effect immediately prior to such

distribution
	 
	 	 	 	 
	CR’

	 	=
	 	the Conversion Rate in effect immediately after such distribution
	 
	 	 	 	 
	SP0

	 	=
	 	the average of the Last Reported Sale Prices of the Common Stock

over the 10 consecutive Trading Day period ending on the

Business Day immediately preceding the Ex-Dividend Date for such

distribution
	 
	 	 	 	 
	FMV

	 	=
	 	the Fair Market Value (as determined by the Board of Directors)

of the shares of Capital Stock, evidences of indebtedness,

assets or property distributed with respect to each outstanding

share of Common Stock on the Record Date for such distribution.

Such adjustment shall become effective immediately prior to 9:00 a.m., New York City time, on the
Business Day following the date fixed for the determination of stockholders entitled to receive
such distribution.

With respect to an adjustment pursuant to this clause (c) where there has been a payment of a
dividend or other distribution on the Common Stock or shares of Capital Stock of any class or
series, or similar equity interest, of or relating to a Subsidiary or other business unit (a
“Spin-Off”), the Conversion Rate in effect immediately before 5:00 p.m., New York City time, on the
effective date for such Spin-Off will be increased based on the following formula:

	 	 	 	 	 
	where,

	 	

	 	

	 
	 	 	 	 
	CR0

	 	=
	 	the Conversion Rate in effect immediately prior to such

distribution
	 
	 	 	 	 
	CR’

	 	=
	 	the Conversion Rate in effect immediately after such distribution
	 
	 	 	 	 
	FMV0

	 	=
	 	the average of the Last Reported Sale Prices of the Capital

Stock or similar equity interest distributed to holders of

Common Stock applicable to one share of Common Stock over the

first 10 consecutive Trading Day period after the effective date

of the Spin-Off
	 
	 	 	 	 
	MP0

	 	=
	 	the average of the Last Reported Sale Prices of Common Stock

over the first 10 consecutive Trading Day period after the

effective date of the Spin-Off.

Such adjustment shall occur on the tenth Trading Day from, and including, the effective date of the
Spin-Off.

(d) If any cash dividend or distribution is made to all or substantially all holders of Common
Stock, other than regular quarterly cash dividends that do not exceed $0.14 per share (the “Initial
Dividend Threshold”), the Conversion Rate will be adjusted based on the following formula:

	 	 	 	 	 
	where,

	 	

	 	

	 
	 	 	 	 
	CR0

	 	=
	 	the Conversion Rate in effect

immediately prior to the Record Date

for such distribution
	 
	 	 	 	 
	CR’

	 	=
	 	the Conversion Rate in effect

immediately after the Record Date for

such distribution
	 
	 	 	 	 
	SP0

	 	=
	 	the Last Reported Sale Price of the

Common Stock on the Trading Day

immediately preceding the Ex-Dividend

Date for such distribution
	 
	 	 	 	 
	C

	 	=
	 	the amount in cash per share the

Company distributes to holders of

Common Stock in excess of the Initial

Dividend Threshold, in the case of a

regular quarterly dividend, or, in the

case of any other dividend or

distribution, the full amount of such

dividend or distribution.

Such adjustment shall become effective immediately after 5:00 p.m., New York City time, on the
Record Date for such dividend or distribution; provided that if such dividend or distribution is
not so paid or made, the Conversion Rate shall again be adjusted to be the Conversion Rate that
would then be in effect if such dividend or distribution had not been declared.

The Initial Dividend Threshold is subject to adjustment in a manner inversely proportional to
adjustments to the Conversion Rate; provided that no adjustment will be made to the dividend
threshold amount for any adjustment made to the Conversion Rate under this clause (d).

(e) If the Company or any of its Subsidiaries make a payment in respect of a tender or
exchange offer for Common Stock, to the extent that the cash and value of any other consideration
included in the payment per share of Common Stock exceeds the 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 (such last date, the “Expiration Time”), the
Conversion Rate will be increased based on the following formula:

	 	 	 	 	 
	where,

	 	

	 	

	 
	 	 	 	 
	CR0

	 	=
	 	the Conversion Rate in effect on the

date such tender or exchange offer

expires
	 
	 	 	 	 
	CR’

	 	=
	 	the Conversion Rate in effect on the

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 purchased in such

tender or exchange offer
	 
	 	 	 	 
	OS0

	 	=
	 	the number of shares of Common Stock

outstanding immediately prior to the

date such tender or exchange offer

expires
	 
	 	 	 	 
	OS’

	 	=
	 	the number of shares of Common Stock

outstanding immediately after the date

such tender or exchange offer expires
	 
	 	 	 	 
	SP’

	 	=
	 	the average of the Last Reported Sale

Prices of Common Stock over the 10

consecutive Trading Day period

commencing on the Trading Day next

succeeding the date such tender or

exchange offer expires.

If the Company is obligated to purchase shares pursuant to any such tender or exchange offer, but
the Company is permanently prevented by applicable law from effecting any such purchases or all
such purchases are rescinded, the Conversion Rate shall again be adjusted to be the Conversion Rate
that would then be in effect if such tender or exchange offer had not been made.

(f) [reserved]

(g) Notwithstanding the foregoing provisions of this Section 12.02, no adjustment shall be
made thereunder, nor shall an adjustment be made to the ability of a Holder to convert, for any
distribution described therein if the Holder will otherwise participate in the distribution without
conversion of such Holder’s Securities.

(h) The Company may (but is not required to) make such increases in the Conversion Rate, in
addition to those required by clauses (a) through (e) of this Section 12.02 as the Board of
Directors considers to be advisable to avoid or diminish any income tax to holders of Common Stock
or rights to purchase Common Stock in connection with a dividend or distribution of shares (or
rights to acquire shares) or any similar event treated as such for income tax purposes.

(i) To the extent permitted by applicable law, the Company from time to time may increase the
Conversion Rate by any amount for any period of at least 20 days if the Board of Directors shall
have made a determination that such increase would be in the best interests of the Company, which
determination shall be conclusive.

(j) Notwithstanding any provision herein to the contrary, no adjustment to the Conversion Rate
need be made:

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

(ii) upon the issuance of any shares of Common Stock or options or rights to purchase
 shares of Common Stock pursuant to any present or future employee, director or consultant
benefit plan or program of or assumed by the Company or any of its Subsidiaries;

(iii) upon the issuance of any shares of Common Stock pursuant to any option,
warrant, right, or exercisable, exchangeable or convertible security not described in
clause (ii) above and outstanding as of the Issue Date;

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

(v) for accrued and unpaid Interest (including any Additional Interest).

To the extent the Securities become convertible into cash, assets or property (other than Capital
Stock of the Company or securities to which Section 12.03 applies), no adjustment shall be made
thereafter as to the cash, assets or property. Interest shall not accrue on such cash, assets or
property.

(k) All calculations under this Section 12.02 shall be made by the Company and shall be made
to the nearest cent or to the nearest one-ten thousandth (1/10,000) of a share, as the case may be.

(l) Whenever the Conversion Rate is adjusted as herein provided, the Company shall promptly
file with the Trustee and any Conversion Agent other than the Trustee an Officers’ Certificate
setting forth the Conversion Rate after such adjustment and setting forth a brief statement of the
facts requiring such adjustment. Unless and until a Trust Officer of the Trustee shall have
received such Officers’ Certificate, the Trustee shall not be deemed to have knowledge of any
adjustment of the Conversion Rate and may assume that the last Conversion Rate of which it has
knowledge is still in effect. Promptly after delivery of such certificate, the Company shall
prepare a notice of such adjustment of the Conversion Rate setting forth the adjusted Conversion
Rate and the date on which each adjustment becomes effective and shall mail such notice of such
adjustment of the Conversion Rate to the Holder of each Security at such Holder’s last address
appearing on the Securities Register provided for in Section 2.05 of this Indenture within 20 days
after execution thereof. Failure to deliver such notice shall not affect the legality or validity
of any such adjustment.

(m) Any case in which this Section 12.02 provides that an adjustment shall become effective
immediately after (i) a Record Date for a dividend or distribution described in Section 12.02(a),
Section 12.02(c) or Section 12.02(d), (ii) the date fixed for the determination of a share split or
combination pursuant to Section 12.02(a), (iii) the date fixed for the determination of Holders
entitled to receive rights or warrants pursuant to 12.02(b), or (iv) the Expiration Time for any
tender or exchange offer pursuant to Section 12.02(e), (each a “Determination Date”), the Company
may elect to defer until the occurrence of the applicable Adjustment Event (as hereinafter defined)
(x) issuing to the Holder of any Security converted after such Determination Date and before the
occurrence of such Adjustment Event, the additional shares of Common Stock or other securities
issuable upon such conversion by reason of the adjustment required by such Adjustment Event over
and above the Common Stock issuable upon such conversion before giving effect to such adjustment
and (y) paying to such Holder any amount in cash in lieu of any fraction pursuant to Section 12.01.
For purposes of this Section 12.02(m), the term “Adjustment Event” shall mean:

(1) in any case referred to in clause (i) and (ii) hereof, the occurrence of such
event,

(2) in any case referred to in clause (iii) hereof, the date of expiration of such
rights or warrants,

(3) in any case referred to in clause (iv) hereof, the date a sale or exchange of
Common Stock pursuant to such tender or exchange offer is consummated and becomes
irrevocable.

(n) For purposes of this Section 12.02, 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.
If the Company pays any dividend or makes any distribution on, or issues any rights, options or
warrants in respect of, shares of Common Stock held in treasury by the Company, the Company shall
not issue, transfer or convey such shares of Common Stock in a manner that would have the effect of
circumventing the provisions of this Section 12.02.

(o) Whenever any provision of this Article 12 requires a calculation of an average of Last
Reported Sale Prices or Daily VWAP over a span of multiple days, the Company will make appropriate
adjustments (determined in good faith by the Board of Directors) to account for any adjustment to
the Conversion Rate that becomes effective, or any event requiring an adjustment to the Conversion
Rate where the Ex-Dividend Date of the event occurs, at any time during the period from which the
average is to be calculated.

Section 12.03 . Adjustment Upon Certain Fundamental Changes. (a) If a Holder elects to
convert Securities pursuant to Section 12.01(a)(iv) above in connection with a transaction
described therein and the transaction (1) has an effective date occurring on or prior to June 15,
2016 and (2) constitutes a Fundamental Change, subject to Section 12.04 below, the Conversion Rate
for such Securities shall be increased by an additional number of shares of Common Stock (the
“Additional Shares”) as described below. Any conversion will be deemed to have occurred in
connection with such Fundamental Change only if such Securities are surrendered for conversion at a
time when the Securities would be convertible in light of the expected or actual occurrence of a
Fundamental Change and notwithstanding the fact that a Security may then be convertible because
another condition to conversion has been satisfied.

(b) The number of Additional Shares will be determined by reference to the table attached as
Schedule A hereto, based on the actual effective date on which the Fundamental Change occurs or
becomes effective (the “Effective Date”) and the Stock Price with respect to such transaction;
provided that if the Stock Price is between two Stock Price amounts set forth in such table or the
Effective Date is between two Effective Dates in the table, the number of Additional Shares will be
determined by a straight-line interpolation between the number of Additional Shares set forth for
the higher and lower Stock Price amounts and the two dates, as applicable, based on a 365-day year;
provided further that if the Stock Price is greater than $184.00 per share (subject to adjustment
as set forth in clause (c) below) or less than $53.54 per share, then no Additional Shares will be
added to the Conversion Rate. Notwithstanding the foregoing, in no event will the total number of
shares of Common Stock issuable upon conversion exceed 18.6776 shares per $1,000 principal amount
of Securities, subject to adjustments in the same manner as the Conversion Rate pursuant to Section
12.02.

(c) The Stock Prices set forth in the first row of the table in Schedule A hereto will be
adjusted as of any date on which the Conversion Rate of the Securities is adjusted pursuant to
Section 12.02. The adjusted Stock Prices will equal the Stock Prices applicable immediately prior
to such adjustment, multiplied by a fraction, the numerator of which is the Conversion Rate
immediately prior to such adjustment and the denominator of which is the Conversion Rate as so
adjusted. The number of Additional Shares set forth in such table will be adjusted in the same
manner as the Conversion Rate as set forth in Section 12.02.

(d) Settlement of Securities tendered for conversion as to which the Conversion Rate will be
increased by Additional Shares pursuant to this Section 12.03 shall occur as follows:

(i) if the last day of the Observation Period for such Securities is on or prior to
the fourth Trading Day immediately preceding the Effective Date, the Company shall deliver
the Settlement Amount (together with cash in lieu of fractional shares), determined in
accordance with Section 12.01(c) and Section 12.01(d) above, on the third Business Day
immediately following the last day of the Observation Period; provided that such
Settlement Amount and related Daily Conversion Values shall be based on the Conversion
Rate without giving effect to the Additional Shares to be added thereto as set forth in
this subsection. As soon as practicable following the Effective Date, the Company shall
calculate an increased Settlement Amount for such Securities (based upon the same
Observation Period and the same Daily VWAP for each Trading Day in such Observation
Period) as if the Conversion Rate had been increased by the number of Additional Shares
pursuant to this subsection. Promptly following the Effective Date, the Company shall
deliver the excess of the cash portion, if any, and Common Stock portion, if any, of such
increased Settlement Amount over the cash and Common Stock portions of the Settlement
Amount calculated without such Additional Shares. Any shares of Common Stock to be
delivered following the Effective Date shall be subject to Section 12.05 and shall be
delivered in Reference Property.

(ii) If the last day of the Observation Period for such Securities is after the
fourth Trading Day immediately preceding the Effective Date, the Company shall deliver the
Settlement Amount (together with cash in lieu of fractional shares) in accordance with
Section 12.01(c) and Section 12.01(d) above (such determination, for the avoidance of
doubt, to include the number of Additional Shares to be added to the Conversion Rate as
set forth in this subsection) on the later to occur of (x) the Business Day following the
Effective Date and (y) the third Business Day immediately following the Conversion Date
relating to such Securities. Any shares of Common Stock to be delivered on or following
the Effective Date shall be subject to Section 12.05 and shall be delivered in Reference
Property.

In no event shall the Company pay any such increase to the Settlement Amount if the transaction
causing the increase to the Conversion Rate pursuant to this subsection never becomes effective.

Section 12.04 . Conversion After a Public Acquirer Change of Control. (a) In the event of a
Public Acquirer Change of Control, the Company may, in lieu of increasing the Conversion Rate by
Additional Shares pursuant to Section 12.03 above and in lieu of application of Section 12.05,
elect to adjust the Conversion Rate and the related conversion obligation such that from and after
the Effective Date of such Public Acquirer Change of Control, Holders shall be entitled to convert
their Securities, subject to the conditions in Section 12.01(a), into cash and a number of shares
of Public Acquirer Common Stock, if applicable, in accordance with Section 12.01. The adjusted
Conversion Rate shall be the Conversion Rate in effect immediately before the Public Acquirer
Change of Control by multiplying it by a fraction:

(i) the numerator of which will be the average of the Last Reported Sale Prices of
the Common Stock for the five consecutive Trading Days prior to but excluding the
Effective Date of such Public Acquirer Change of Control, and

(ii) the denominator of which will be the average of the Last Reported Sale Prices of
the Public Acquirer Common Stock for the five consecutive Trading Days commencing on the
Trading Day next succeeding the Effective Date of such Public Acquirer Change of Control.

(b) In order to make the election pursuant to this Section 12.04, the Company and the issuer
of the Public Acquirer Common Stock shall execute with the Trustee a supplemental indenture
providing that each Security shall be exchangeable into Public Acquirer Common Stock and execute an
amendment to the Registration Rights Agreement (to the extent any Registrable Securities (as
defined therein) remain outstanding) to make the provisions thereof to apply to the Public Acquirer
Common Stock. Such supplemental indenture shall provide for provisions and adjustments which shall
be a nearly equivalent as may be practicable to the provisions and adjustments provided for in this
Article 12 as determined in good faith by the Board of Directors of the Company or such issuer
(which shall be conclusive).

(c) At least 10 Trading Days prior to the expected Effective Date of a Fundamental Change that
is also a Public Acquirer Change of Control, the Company will provide a notice to all Holders, the
Trustee and the Paying Agent stating whether the Company (i) elects to adjust the Conversion Rate
and the related conversion obligation as set forth in this Section 12.04 or (ii) does not elect to
so adjust the Conversion Rate and the related conversion obligation, in which case the Holders will
have the right to convert Securities and, if applicable, receive Additional Shares as set forth in
Section 12.03.

Section 12.05 . Effect of Reclassification, Consolidation, Merger or Sale. (a) Except as
otherwise provided in Section 12.04, if any of the following events occur: (i) any
recapitalization, reclassification or change of the outstanding shares of Common Stock (other than
a subdivision or combination to which Section 12.02(a) applies), (ii) any consolidation, merger,
binding share exchange or combination of the Company with another Person as a result of which
holders of Common Stock shall be entitled to receive cash, securities or other property (or any
combination thereof) with respect to or in exchange for such Common Stock, or (iii) any sale, lease
or other transfer of the consolidated properties and assets of the Company and its Subsidiaries
substantially as an entirety to any other Person as a result of which holders of Common Stock shall
be entitled to receive cash, securities or other property (or any combination thereof) with respect
to or in exchange for such Common Stock (any such event or transaction, a “Reorganization Event”),
then after the effective time of such Reorganization Event, the Securities shall only be
convertible into the kind and amount of cash, securities or other property (and in the same
proportion) receivable (the “Reference Property”) upon such Reorganization Event by a holder of a
number of shares of Common Stock equal to the Conversion Rate immediately prior to such
Reorganization Event and the Company or successor Person shall execute a supplemental indenture to
such effect. For purposes of the foregoing, the type and amount of consideration that a holder of
Common Stock would have been entitled to receive in the case of any such Reorganization Event that
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) will be deemed to be
the weighted average of the types and amounts of consideration received by the holders of Common
Stock that affirmatively make such an election. Such supplemental indenture shall provide for
provisions and adjustments which shall be as nearly equivalent as may be practicable to the
provisions and adjustments provided for in this Article 12, Article 9 and Article 11 and the
definition of Fundamental Change, as appropriate, as determined in good faith by the Company (which
determination shall be conclusive and binding), to make such provisions apply to such other Person
if different from the original issuer of the Securities.

(b) Following the effective time of any such Reorganization Event, settlement of Securities
converted shall be in cash and units of Reference Property determined in accordance with Section
12.01(c) above based on the Daily Conversion Value and Daily VWAP of such Reference Property. For
the purposes of determining such Daily Conversion Value and Daily VWAP, (i) if the Reference
Property includes securities for which the price can be determined in a manner contemplated by the
definition of Daily VWAP, then the value of such securities shall be determined in accordance with
the principles set forth in such definition, as determined in good faith by the Company (which
determination shall be conclusive and binding); (ii) if the Reference Property includes other
property (other than securities as to which clause (i) applies or cash), then the value of such
property shall be the Fair Market Value of such property as determined by the Company’s Board of
Directors in good faith; and (iii) if the Reference Property includes cash, then the value of such
cash shall be the amount thereof.

(c) Any issuer of securities included in the Reference Property shall execute an amendment to
the Registration Rights Agreement (to the extent any Registrable Securities (as defined therein)
remain outstanding) to make the provisions thereof applicable to such securities included in the
Applicable Consideration.

(d) The Company shall cause notice of the execution of any supplemental indenture required by
this Section 12.05 to be mailed to each Holder, at its address appearing on the Securities Register
provided for in Section 2.05 of this Indenture, within 20 calendar days after execution thereof.
Failure to deliver such notice shall not affect the legality or validity of such supplemental
indenture.

(e) The above provisions of this Section 12.05 shall similarly apply to successive
Reorganization Events.

(f) If this Section 12.05 applies to any event or occurrence, Section 12.02 shall not apply in
respect of such event or occurrence.

(g) The Company shall not become a party to any Reorganization Event unless its terms are
consistent with the foregoing. None of the foregoing provisions shall affect the right of a Holder
of Securities to convert the Securities into cash and shares of Common Stock, if applicable, as set
forth in Section 12.01 prior to the effective time of such Reorganization Event.

Section 12.06 . Responsibility of Trustee. The Trustee and any other Conversion Agent shall
not at any time be under any duty or responsibility to the Company or any Holder of Securities to
determine the Conversion Rate, or whether any facts exist which may require any adjustment of the
Conversion Rate, or with respect to the nature or extent or calculation of any such adjustment when
made, or with respect to the method 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 or property, which may at any time be
issued or delivered upon the conversion of any Security; 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 cash or
shares of Common Stock or stock certificates or other securities or property upon the surrender of
any Security for the purpose of conversion or to comply with any of the duties, responsibilities or
covenants of the Company contained in this Article 12. 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 12.05 relating either to the kind or amount of shares of stock or securities or
property (including cash) receivable by Holders upon the conversion of their Securities after any
Reorganization Event or to any adjustment to be made with respect thereto, but, subject to the
provisions of Section 7.01, may accept as conclusive evidence of the correctness of any such
provisions, and shall be protected in relying upon, an Officers’ Certificate with respect thereto.

Section 12.07 . Notice to Holders Prior to Certain Actions. Except where notice is required
pursuant to Section 12.01(a)(iv), in case:

(a) the Company shall declare a dividend (or any other distribution) on its Common Stock that
would require an adjustment in the Conversion Rate pursuant to Section 12.02; or

(b) the Company shall authorize the granting to the holders of all or substantially all 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 Conversion Rate pursuant to Section
12.02; or

(c) of any reclassification or reorganization of the Common Stock of the Company (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 cause to be filed with the Trustee and to be mailed to each Holder of Securities
at his address appearing on the Securities Register provided for in Section 2.05 of this Indenture,
as promptly as possible but in any event at least three (3) calendar days prior to the applicable
date hereinafter specified, a notice stating (x) 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 (y) the date on which such reclassification,
consolidation, merger, sale, transfer, dissolution, liquidation or winding up is expected to become
effective or occur, 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 12.08 . Stockholder Rights Plan. To the extent that the Company has a rights plan in
effect upon conversion of the Securities into Common Stock, the Holder will receive, in addition to
the Common Stock, the rights under the rights plan, unless prior to any conversion, the rights have
separated from the Common Stock, in which case, and only in such case, the Conversion Rate will be
adjusted at the time of separation as if the Company distributed to all holders of Common Stock
shares of the Company’s Capital Stock, evidences of indebtedness or assets as described in Section
12.02(c) above, subject to readjustment in the event of the expiration, termination or redemption
of such rights. In lieu of any such adjustment, the Company may amend such applicable stockholder
rights agreement to provide that upon conversion of the Securities the Holders will receive, in
addition to the Common Stock issuable upon such conversion, the rights which would have attached to
such Common Stock if the rights had not become separated from the Common Stock under such
applicable stockholder rights agreement.

Securities owned by the Company or by any Person directly or indirectly controlling or controlled
by or under direct or indirect common control with the Company shall be disregarded and deemed not
to be outstanding, except that, for the purpose of determining whether the Trustee shall be
protected in relying on any such direction, waiver or consent, only Securities which a Trust
Officer of the Trustee actually knows are so owned shall be so disregarded. Also, subject to the
foregoing, only Securities outstanding at the time shall be considered in any such determination.

Section 13.07 . Rules by Trustee, Paying Agent and Registrar. The Trustee may make
reasonable rules for action by, or a meeting of, Holders. The Registrar and the Paying Agent may
make reasonable rules for their functions.

Section 13.08 . Legal Holidays. A “Legal Holiday” is a Saturday, a Sunday or other day on
which commercial banking institutions are authorized or required to be closed in New York City or
Houston, Texas. If a payment date is a Legal Holiday, payment shall be made on the next succeeding
day that is not a Legal Holiday, and no interest or Additional Interest, if any, shall accrue for
the intervening period. If a Regular Record Date is a Legal Holiday, the record date shall not be
affected.

Section 13.09 . Governing Law. THIS INDENTURE AND THE SECURITIES SHALL BE GOVERNED BY, AND
CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

Section 13.10 . No Recourse Against Others. An incorporator, director, officer, employee,
Affiliate or stockholder of the Company, solely by reason of this status, shall not have any
liability for any obligations of the Company under the Securities, this Indenture or for any claim
based on, in respect of or by reason of such obligations or their creation. By accepting a
Security, each Holder shall waive and release all such liability. The waiver and release shall be
part of the consideration for the issue of the Securities.

Section 13.11 . Successors. All agreements of the Company in this Indenture and the
Securities shall bind their respective successors. All agreements of the Trustee in this Indenture
shall bind its successors.

Section 13.12 . Multiple Originals. The parties may sign any number of copies of this
Indenture. Each signed copy shall be an original, but all of them together represent the same
agreement. One signed copy is enough to prove this Indenture.

Section 13.13 . Qualification of Indenture. The Company shall qualify this Indenture under
the TIA in accordance with the terms and conditions of the Registration Rights Agreement and shall
pay all reasonable costs and expenses (including attorneys’ fees and expenses for the Company, the
Trustee and the Holders) incurred in connection therewith, including, but not limited to, costs and
expenses of qualification of this Indenture and the Securities and the printing of this Indenture
and the Securities.

Section 13.14 . Table of Contents; Headings. The table of contents, cross-reference sheet
and headings of the Articles and Sections of this Indenture have been inserted for convenience of
reference only, are not intended to be considered a part hereof and shall not modify or restrict
any of the terms or provisions hereof.

Section 13.15 . Severability Clause. In case any provision in this Indenture shall be
invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining
provisions shall not in any way be affected or impaired thereby and such provision shall be
ineffective only to the extent of such invalidity, illegality or unenforceability.

Section 13.16 . Calculations. Except as otherwise provided herein, the Company will be
responsible for making all calculations called for under the Indenture and the Securities. The
Company will make all such calculations in good faith and, absent manifest error, its calculations
will be final and binding on Holders. The Company upon request will provide a schedule of its
calculations to each of the Trustee and the Conversion Agent, and each of the Trustee and
Conversion Agent is entitled to rely conclusively upon the accuracy of the Company’s calculations
without independent verification. The Trustee will deliver a copy of such schedule to any Holder

TERMS OF SECURITIES

2.25% Convertible Senior Notes due 2036

The Company issued this Securities under an Indenture dated as of June 26, 2006 (as it may be
amended or supplemented from time to time in accordance with the terms thereof, the “Indenture”),
among the Company and the Trustee, to which 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. Additional Securities may be issued under the Indenture in an unlimited
aggregate principal amount subject to certain conditions specified in the Indenture.

	1)	 	Interest

Group 1 Automotive, Inc., a Delaware corporation (such corporation, and its successors and
assigns under the Indenture hereinafter referred to, being herein called the “Company”), promises
to pay interest on the principal amount of this Security at the rate of 2.25% per annum until
June 15, 2016 and at a rate of 2.00% per annum thereafter.

The Company will pay interest semiannually on June 15 and December 15 of each year commencing
December 15, 2006. Interest on the Securities will accrue from the most recent date to which
interest has been paid on the Securities or, if no interest has been paid, from June 26, 2006.
Interest will be computed on the basis of a 360-day year of twelve 30-day months.

	2)	 	Method of Payment

By no later than 11:00 a.m. (New York City time) on the date on which any principal of or
interest (including any Additional Interest), on any Security is due and payable, the Company shall
deposit with the Paying Agent money sufficient to pay such amount. The Company will pay principal
and interest in money of the United States that at the time of payment is legal tender for payment
of public and private debts. Payments in respect of Securities represented by a Global Security
(including principal and interest (including any Additional Interest)) will be made by wire
transfer of immediately available funds to the accounts specified by The Depository Trust Company.
The Company will pay principal of Definitive Securities at the office or agency designated by the
Company for such purpose. Interest (including any Additional Interest), on Definitive Securities
will be payable (i) to Holders having an aggregate principal amount of $5,000,000 or less, by check
mailed to the Holders of these Securities and (ii) to Holders having an aggregate principal amount
of more than $5,000,000, either by check mailed to each Holder or, upon application by a Holder to
the Registrar not later than the relevant record date, by wire transfer in immediately available
funds to that Holder’s account within the United States, which application shall remain in effect
until the Holder notifies, in writing, the Registrar to the contrary.

	3)	 	Redemption

No sinking fund is provided for the Securities. Subject to certain conditions specified in
the Indenture, the Securities will be redeemable, at the option of the Company, in whole at any
time or in part from time to time, at any time (i) on and after June 20, 2011 but prior to June 15,
2016 if the Last Reported Sale Price of the Company’s Common Stock is greater than or equal to 130%
of the Conversion Price then in effect for at least 20 Trading Days within a period of 30
consecutive Trading Days ending on the Trading Day prior to the date on which the notice of
redemption is mailed, and (ii) at any time and from time to time on or after June 15, 2016, at a
Redemption Price specified in the Indenture.

	4)	 	Purchase By the Company at the Option of the Holder; Purchase at the Option of the Holder
Upon a Fundamental Change

	 	a)	 	Subject to the terms and conditions of the Indenture, a Holder shall have the option
to require the Company to purchase all or a portion of its Securities held by such Holder
on June 15, 2016 and June 15, 2026 at a Purchase Price specified in the Indenture.

	 	b)	 	If a Fundamental Change shall occur at any time, each Holder shall have the right, at
such Holder’s option and subject to the terms and conditions of the Indenture, to require
the Company to purchase all or a portion of its Securities at a Fundamental Change
Purchase Price specified in the Indenture.

	5)	 	Conversion

Subject to the conditions and procedures set forth in the Indenture, and during the periods
specified in the Indenture, a Holder may convert Securities, on or prior to the close of business
on the Business Day immediately preceding Stated Maturity, into cash and shares of Common Stock, if
any, at the Conversion Rate.

The initial Conversion Rate is 16.8267 shares of Common Stock per $1,000 principal amount of
Securities, subject to adjustment in certain events described in the Indenture. Upon conversion,
the Company will pay cash and shares of Common Stock, if any, based on a Daily Conversion Value
calculated on a proportionate basis for each day of the 25-day Observation Period, as set forth in
the Indenture. The Company shall deliver cash in lieu of any fractional share of Common Stock.

A Holder may convert a portion of the Securities only if the principal amount of such portion
is $1,000 or a multiple of $1,000. No payment or adjustment shall be made for dividends on the
Common Stock except as provided in the Indenture.

	6)	 	Denominations; Transfer; Exchange

The Securities are in registered form without coupons in denominations of principal amount of
$1,000 and multiples of $1,000. A Holder may transfer or exchange Securities in accordance with
the Indenture. The Registrar may require a Holder, among other things, to furnish appropriate
endorsements or transfer documents and to pay any taxes and fees required by law or permitted by
the Indenture. The Registrar need not register the transfer of or exchange of Securities (i) for a
period of 15 days prior to the mailing of a notice of redemption of Securities selected for
redemption under Article 5 of the Indenture; (ii) so selected for redemption or, if a portion of
any Security is selected for redemption, the portion thereof selected for redemption; or (iii)
surrendered for conversion or, if a portion of any Security is surrendered for conversion, the
portion thereof surrendered for conversion.

	7)	 	Persons Deemed Owners

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

	8)	 	Unclaimed Money

If money for the payment of principal or interest (including any Additional Interest) remains
unclaimed for two years, the Trustee or Paying Agent shall pay the money back to the Company.
After any such payment, Holders entitled to the money must look only to the Company and not to the
Trustee for payment.

	9)	 	Amendment, Waiver

Subject to certain exceptions, the Indenture contains provisions permitting an amendment of
the Indenture or the Securities with the written consent of the Holders of at least a majority in
principal amount of the then outstanding Securities and the waiver of any Event of Default (other
than with respect to nonpayment or in respect of a provision that cannot be amended without the
written consent of each Holder affected) or noncompliance with any provision with the written
consent of the Holders of a majority in principal amount of the then outstanding Securities.

In addition, the Indenture permits an amendment of the Indenture or the Security without the
consent of any Holder under circumstances specified in the Indenture.

	10)	 	Defaults and Remedies

If an Event of Default specified in the Indenture occurs and is continuing, the Trustee or the
Holders of at least 25% in principal amount of the Securities may declare all the Securities by
notice to the Company to be due and payable immediately. In addition, certain specified Events of
Default will cause the Securities to become immediately due and payable without further action by
the Holders.

Holders may not enforce the Indenture or the Securities except as provided in the Indenture.
The Trustee may refuse to enforce the Indenture or the Securities unless it receives reasonable
indemnity or security. Subject to certain limitations, Holders of a majority in principal amount
of the Securities may direct the Trustee in its exercise of any trust or power. The Trustee may
withhold from Holders notice of any continuing Default or Event of Default (except a Default or
Event of Default in payment of principal or interest (including any Additional Interest)) if it
determines that withholding notice is in their interest.

	11)	 	Trustee Dealings with the Company

Subject to certain limitations set forth in the Indenture, the Trustee under the Indenture, in
its individual or any other capacity, may become the owner or pledgee of Securities and may
otherwise deal with and collect obligations owed to it by the Company or its Affiliates and may
otherwise deal with the Company or its Affiliates with the same rights it would have if it were not
Trustee.

	12)	 	No Recourse Against Others

An incorporator, director, officer, employee, Affiliate or stockholder, of the Company, solely
by reason of this status, shall not have any liability for any obligations of the Company under the
Securities or the Indenture or for any claim based on, in respect of or by reason of such
obligations or their creation. By accepting a Security, each Holder waives and releases all such
liability. The waiver and release are part of the consideration for the issue of the Securities.

	13)	 	Authentication

This Security shall not be valid until an authorized signatory of the Trustee manually
authenticates this Security.

	14)	 	Abbreviations

Customary abbreviations may be used in the name of a Holder or an assignee, such as TEN COM
(=tenants in common), TEN ENT (=tenants by the entirety), JT TEN (=joint tenants with rights of
survivorship and not as tenants in common), CUST (=custodian) and U/G/M/A (=Uniform Gift to Minors
Act).

	15)	 	CUSIP Numbers

Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification
Procedures, the Company has caused CUSIP numbers to be printed on the Securities and has directed
the Trustee to use CUSIP numbers in notices of redemption as a convenience to Holders. No
representation is made as to the accuracy of such numbers either as printed on the Securities or as
contained in any notice of redemption, and reliance may be placed only on the other identification
numbers placed thereon.

	16)	 	Governing Law

This Security shall be governed by, and construed in accordance with, the laws of the State of
New York.

The Company will furnish to any Holder upon written request and without charge to the Holder a
copy of the Indenture which has in it the text of this Security. Requests may be made to:

2. Registration Under the Securities Act.

(a) The Company agrees to file under the Securities Act as promptly as practicable but
in any event within 90 days after the Closing Date a shelf registration statement providing
for the registration of, and the sale on a continuous or delayed basis by the Holders of,
all of the Registrable Securities, and, if necessary by the Company of all of the Shares,
pursuant to Rule 415 or any similar rule that may be adopted by the Commission. The Company
agrees to use its reasonable efforts to cause the Shelf Registration Statement to become or
be declared effective under the Securities Act within 180 days after the Closing Date and to
keep such Shelf Registration Statement continuously effective until each of the Registrable
Securities covered by the Shelf Registration Statement ceases to be a Registrable Security
(the “Effective Period”). The Company’s securityholders (other than Holders of Registrable
Securities) shall not have the right to include any of the Company’s securities in the Shelf
Registration Statement.

(b) The Company further agrees that it shall cause the Shelf Registration Statement and
the related Prospectus and any amendment or supplement thereto, as of the effective date of
the Shelf Registration Statement or such amendment or supplement, (i) to comply in all
material respects with the applicable requirements of the Securities Act; and (ii) not to
contain any untrue statement of a material fact or omit to state a material fact required to
be stated therein or necessary in order to make the statements therein (in the case of the
Prospectus, in the light of the circumstances under which they were made) not misleading,
and the Company agrees to furnish to the Holders of the Registrable Securities copies of any
supplement or amendment upon the request of such Holder prior to its being used or promptly
following its filing with the Commission; provided, however, that the Company shall have no
obligation to deliver to Holders of Registrable Securities copies of any amendment
consisting exclusively of an Exchange Act report or other Exchange Act filing otherwise
publicly available on the Company’s website. If the Shelf Registration Statement, as
amended or supplemented from time to time, ceases to be effective for any reason at any time
during the Effective Period (other than because all Registrable Securities registered
thereunder shall have been sold pursuant thereto or shall have otherwise ceased to be
Registrable Securities), the Company shall use its reasonable efforts to obtain the prompt
withdrawal of any order suspending the effectiveness thereof.

(c) Each Holder of Registrable Securities agrees that if such Holder wishes to sell
Registrable Securities pursuant to the Shelf Registration Statement and related Prospectus,
it will do so only in accordance with this Section 2(c) and Section 3(b). From and after
the date the Shelf Registration Statement is declared effective, the Company shall, as
promptly as is practicable after the date a Notice and Questionnaire is delivered, and in
any event within fifteen (15) days after the date of receipt of such Notice and
Questionnaire, or if the use of the Prospectus has been suspended by the Company under
Section 3(b) hereof at the time of receipt of the Notice and Questionnaire, fifteen (15)
days after the expiration of the period during which the use of the Prospectus is suspended:

(i) if required by applicable law, file with the Commission a post-effective
amendment to the Shelf Registration Statement or prepare and if required by
applicable law, file a supplement to the related Prospectus or a supplement or
amendment to any document incorporated therein by reference or file any other
required document so that the Holder delivering such Notice and Questionnaire is
named as a selling security holder in the Shelf Registration Statement and the
related Prospectus in such a manner as to permit such Holder to deliver such
Prospectus to purchasers of the Registrable Securities in accordance with applicable
law and, if the Company shall file a post-effective amendment to the Shelf
Registration Statement, use its reasonable efforts to cause such post-effective
amendment to be declared effective under the Securities Act as promptly as is
practicable. Notwithstanding the foregoing, the Company shall not be required to
file more than one post-effective amendment to the Shelf Registration Statement or
supplement to the related Prospectus during any thirty (30) day period;

(ii) provide such Holder copies of any documents filed pursuant to
Section 2(c)(i); and

(iii) notify such Holder as promptly as practicable after the effectiveness
under the Securities Act of any post-effective amendment filed pursuant to
Section 2(c)(i);

Notwithstanding anything contained herein to the contrary, the Company shall be under no
obligation to name any Holder that is not a Notice Holder as a selling securityholder in any
Shelf Registration Statement or related Prospectus; provided, however, that any Holder that
becomes a Notice Holder pursuant to the provisions of this Section 2(c) (whether or not such
Holder was a Notice Holder at the time the Shelf Registration Statement was declared
effective) shall be named as a selling securityholder in the Shelf Registration Statement or
related Prospectus in accordance with the requirements of this Section 2(c).

(d) If any of the following events (any such event a “Registration Default”) shall
occur, then additional interest (the “Additional Interest”) shall become payable by the
Company to Holders in respect of the Notes as follows:

(i) if the Shelf Registration Statement is not filed with the Commission within
90 days following the Closing Date, then commencing on the 91st day after
the Closing Date, Additional Interest shall accrue on the principal amount of the
outstanding Notes at a rate of 0.25% per annum for the first 90 days following such
91st day and at a rate of 0.5% per annum thereafter; or

(ii) if the Shelf Registration Statement is not declared effective by the
Commission within 180 days following the Closing Date, then commencing on the
181st day after the Closing Date, Additional Interest shall accrue on the
principal amount of the outstanding Notes at a rate of 0.25% per annum for the first
90 days following such 181st day and at a rate of 0.5% per annum
thereafter; or

(iii) if the Shelf Registration Statement has been declared effective but such
Shelf Registration Statement ceases to be effective at any time during the Effective
Period (other than pursuant to Section 3(b) hereof), then commencing on the day such
Shelf Registration Statement ceases to be effective, Additional Interest shall
accrue on the principal amount of the outstanding Notes that are Registrable
Securities at a rate of 0.25% per annum for the first 90 days following such date on
which the Shelf Registration Statement ceases to be effective and at a rate of 0.5%
per annum thereafter; or

(iv) if the aggregate duration of Deferral Periods in any period exceeds the
number of days permitted in respect of such period pursuant to Section 3(b) hereof,
then commencing on the day the aggregate duration of Deferral Periods in any period
exceeds the number of days permitted in respect of such period (and again on the
first day of any subsequent Deferral Period during such period), Additional Interest
shall accrue on the principal amount of the outstanding Notes that are Registrable
Securities at a rate of 0.25% per annum for the first 90 days and at a rate of 0.5%
per annum thereafter;

provided, however, that the Additional Interest rate on the Notes shall not exceed in the
aggregate 0.5% per annum and shall not be payable under more than one clause above for any
given period of time, except that if Additional Interest would be payable under more than
one clause above, but at a rate of 0.25% per annum under one clause and at a rate of 0.5%
per annum under the other, then the Additional Interest rate shall be the higher rate of
0.5% per annum; provided further, however, that (1) upon the filing of the Shelf
Registration Statement (in the case of clause (i) above), (2) upon the effectiveness of the
Shelf Registration Statement (in the case of clause (ii) above), (3) upon the effectiveness
of the Shelf Registration Statement which had ceased to remain effective (in the case of
clause (iii) above), (4) upon the termination of the Deferral Period that caused the limit
on the aggregate duration of Deferral Periods in a period set forth in Section 3(b) to be
exceeded (in the case of clause (iv) above), (5) upon the termination of certain transfer
restrictions on the Securities as a result of the application of Rule 144(k) or any
successor provision or (6) for any period after the second anniversary from the Closing
Date, Additional Interest on the Notes as a result of such clause, as the case may be, shall
cease to accrue.

Additional Interest on the Notes, if any, will be payable in cash on June 15 and
December 15 of each year (the “Additional Interest Payment Date”) to holders of record of
outstanding Notes that are Registrable Securities at the close of business on June 1 or
December 1, as the case may be, immediately preceding the relevant interest payment date;
provided that any Additional Interest accrued with respect to any Notes or portion thereof
called for redemption on a redemption date or converted into Shares on a conversion date
prior to the Registration Default shall, in any such event, be paid instead to the Holder
who submitted such Notes or portion thereof for redemption or conversion on the applicable
redemption date or conversion date, as the case may be, on such date (or promptly following
the conversion date, in the case of conversion). Following the cure of all Registration
Defaults requiring the payment of Additional Interest to the Holders of Notes that are
Registrable Securities pursuant to this Section, the accrual of Additional Interest will
cease (without in any way limiting the effect of any subsequent Registration Default
requiring the payment of Additional Interest).

The Company shall notify the Trustee immediately upon the happening of each and every
Registration Default. The Trustee shall be entitled, on behalf of Holders of Securities, to
seek any available remedy for the enforcement of this Agreement, including for the payment
of any Additional Interest. Notwithstanding the foregoing, the parties agree that the sole
monetary damages payable for a violation of the terms of this Agreement with respect to
which additional monetary amounts are expressly provided shall be as set forth in this
Section 2(d). Nothing shall preclude a Notice Holder or Holder of Registrable Securities
from pursuing or obtaining specific performance or other equitable relief with respect to
this Agreement.

3. Registration Procedures.

The following provisions shall apply to the Shelf Registration Statement filed pursuant to
Section 2:

(a) The Company shall:

(ii) before filing any Shelf Registration Statement or Prospectus or any

(iv) promptly notify the Notice Holders of Registrable Securities that have

concerning) any event or the existence of any fact (a “Material Event”) as a result
of which any Shelf Registration Statement shall contain any untrue statement of a
material fact or omit to state any material fact required to be stated therein or
necessary to make the statements therein not misleading, or any Prospectus shall
contain any untrue statement of a material fact or omit to state any material fact
required to be stated therein or necessary to make the statements therein, in the
light of the circumstances under which they were made, not misleading (provided,
however, that no notice by the Company shall be required pursuant to this clause (E)
in the event that the Company either promptly files a prospectus supplement to
update the Prospectus or a Form 8-K or other appropriate Exchange Act report that is
incorporated by reference into the Shelf Registration Statement, which, in either
case, contains the requisite information with respect to such Material Event that
results in such Shelf Registration Statement no longer containing any untrue
statement of material fact or omitting to state a material fact necessary to make
the statements contained therein not misleading), (F) of the determination by the
Company that a post-effective amendment to the Shelf Registration Statement (other
than for the purpose of naming a Notice Holder as a selling securityholder therein)
will be filed with the Commission, which notice may, at the discretion of the
Company (or as required pursuant to Section 3(b)), state that it constitutes a
Deferral Notice, in which event the provisions of Section 3(b) shall apply or (G) at
any time when a Prospectus is required to be delivered under the Securities Act,
that the Shelf Registration Statement, Prospectus, Prospectus amendment or
supplement or post-effective amendment does not conform in all material respects to
the applicable requirements of the Securities Act and the Trust Indenture Act and
the rules and regulations of the Commission thereunder;

(v) prior to any public offering of the Registrable Securities pursuant to the
Shelf Registration Statement, use its reasonable efforts to register or qualify, or
cooperate with the Notice Holders of Securities included therein and their
respective counsel in connection with the registration or qualification of, such
Securities for offer and sale under the securities or blue sky laws of such
jurisdictions as any such Notice Holders reasonably requests in writing and do any
and all other acts or things reasonably necessary or advisable to enable the offer
and sale in such jurisdictions of the Securities covered by the Shelf Registration
Statement; prior to any public offering of the Registrable Securities pursuant to
the Shelf Registration Statement, use its reasonable efforts to keep each such
registration or qualification (or exemption therefrom) effective during the
Effective Period in connection with such Notice Holder’s offer and sale of
Registrable Securities pursuant to such registration or qualification (or exemption
therefrom) and do any and all other acts or things reasonably necessary or advisable
to enable the disposition in such jurisdictions of such Registrable Securities in
the manner set forth in the Shelf Registration Statement and the related Prospectus;
provided that the Company will not be required to qualify generally to do business
in any jurisdiction where it is not then so qualified or to take any action which
would subject it to general service of process or to taxation in any such
jurisdiction where it is not then so subject;

(vi) use its reasonable efforts to prevent the issuance of, and if issued, to
obtain the withdrawal of any order suspending the effectiveness of the Shelf
Registration Statement or any post-effective amendment thereto, and to lift any
suspension of the qualification of any of the Registrable Securities for sale in any
jurisdiction in which they have been qualified for sale, in each case at the
earliest practicable date;

(vii) upon reasonable notice, for a reasonable period prior to the filing of
the Shelf Registration Statement, and throughout the Effective Period, (i) make
reasonably available for inspection by a representative of, and Special Counsel
acting for, Majority Holders of the Securities being sold and any underwriter (and
its counsel) participating in any disposition of Securities pursuant to such Shelf
Registration Statement, all relevant financial and other records, pertinent
corporate documents and properties of the Company and its subsidiaries and (ii) use
reasonable efforts to have their officers, directors, employees, accountants and
counsel supply all relevant information reasonably requested by such representative,
Special Counsel or any such underwriter in connection with such Shelf Registration
Statement;

(viii) if requested by Majority Holders of the Securities being sold in an
underwriting, its Special Counsel or the managing underwriters (if any) in
connection with such Shelf Registration Statement, use its reasonable efforts to
cause (i) its counsel to deliver an opinion relating to the Shelf Registration
Statement and the Securities in customary form, (ii) its officers to execute and
deliver all customary documents and certificates requested by the Majority Holders
of the Securities being sold, their Special Counsel or the managing underwriters (if
any) and (iii) its independent public accountants to provide a comfort letter or
letters in customary form, subject to receipt of appropriate documentation as
contemplated, and only if permitted, by Statement of Auditing Standards No. 72;

(ix) if reasonably requested by the Initial Purchasers or any Notice Holder,
promptly incorporate in a prospectus supplement or post-effective amendment to the
Shelf Registration Statement such information as the Initial Purchasers or such
Notice Holder shall, on the basis of a written opinion of nationally-recognized
counsel experienced in such matters, determine to be required to be included therein
by applicable law and make any required filings of such prospectus supplement or
such post-effective amendment; provided, that the Company shall not be required to
take any actions under this Section 3(a)(ix) that are not, in the reasonable opinion
of counsel for the Company, in compliance with applicable law;

(x) promptly furnish to each Notice Holder and the Initial Purchasers, upon
their request and without charge, at least one (1) conformed copy of the Shelf
Registration Statement and any amendments thereto, including financial statements
but excluding schedules, all documents incorporated or deemed to be incorporated
therein by reference and all exhibits; provided, however, that the Company shall
have no obligation to deliver to Notice Holders or the Initial Purchasers a copy of
any amendment consisting exclusively of an Exchange Act report or other Exchange Act
filing otherwise publicly available on the Company’s website;

(xi) during the Effective Period, deliver to each Notice Holder in connection
with any sale of Registrable Securities pursuant to the Shelf Registration
Statement, upon their request and without charge, as many copies of the Prospectus
relating to such Registrable Securities (including each preliminary prospectus) and
any amendment or supplement thereto as such Notice Holder may reasonably request;
and the Company hereby consents (except during such periods that a Deferral Notice
is outstanding and has not been revoked) to the use of such Prospectus or each
amendment or supplement thereto by each Notice Holder in connection with any
offering and sale of the Registrable Securities covered by such Prospectus or any
amendment or supplement thereto in the manner set forth therein; and

(xii) cooperate with the Notice Holders of Securities to facilitate the timely
preparation and delivery of certificates representing Securities to be sold pursuant
to the Shelf Registration Statement free of any restrictive legends and in such
denominations and registered in such names as the Holders thereof may request in
writing at least two business days prior to sales of Securities pursuant to such
Shelf Registration Statement.

(b) Upon (A) the issuance by the Commission of a stop order suspending the
effectiveness of the Shelf Registration Statement or the initiation of proceedings with
respect to the Shelf Registration Statement under Section 8(d) or 8(e) of the Securities
Act, (B) the occurrence of any event or the existence of any Material Event as a result of
which the Shelf Registration Statement shall contain any untrue statement of a material fact
or omit to state any material fact required to be stated therein or necessary to make the
statements therein not misleading, or any Prospectus shall contain any untrue statement of a
material fact or omit to state any material fact required to be stated therein or necessary
to make the statements therein, in the light of the circumstances under which they were
made, not misleading, or (C) the occurrence or existence of any corporate development that,
in the discretion of the Company, makes it appropriate to suspend the availability of the
Shelf Registration Statement and the related Prospectus, the Company will (i) in the case of
clause (B) above, subject to the third sentence of this provision, as promptly as
practicable prepare and file a post-effective amendment to such Shelf Registration Statement
or a supplement to the related Prospectus or any document incorporated therein by reference
or file any other required document that would be incorporated by reference into such Shelf
Registration Statement and Prospectus so that such Shelf Registration Statement does not
contain any untrue statement of a material fact or omit to state any material fact required
to be stated therein or necessary to make the statements therein not misleading, and such
Prospectus does not contain any untrue statement of a material fact or omit to state any
material fact required to be stated therein or necessary to make the statements therein, in
the light of the circumstances under which they were made, not misleading, as thereafter
delivered to the purchasers of the Registrable Securities being sold thereunder, and, in the
case of a post-effective amendment to the Shelf Registration Statement, subject to the third
sentence of this provision, use reasonable efforts to cause it to be declared effective as
promptly as is practicable, and (ii) give notice to the Notice Holders that the availability
of the Shelf Registration Statement is suspended (a “Deferral Notice”). Upon receipt of any
Deferral Notice, each Notice Holder agrees not to sell any Registrable Securities pursuant
to the Shelf Registration Statement until such Notice Holder’s receipt of copies of the
supplemented or amended Prospectus provided for in clause (i) above, or until it is advised
in writing by the Company that the Prospectus may be used, and has received copies of any
additional or supplemental filings that are incorporated or deemed incorporated by reference
in such Prospectus. The Company will use its reasonable efforts to ensure that the use of
the Prospectus may be resumed (x) in the case of clause (A) above, as promptly as
practicable, (y) in the case of clause (B) above, as soon as, in the sole judgment of the
Company, public disclosure of such Material Event would not be prejudicial to or contrary to
the interests of the Company or, if necessary to avoid unreasonable burden or expense, as
soon as practicable thereafter and (z) in the case of clause (C) above, as soon as, in the
discretion of the Company, such suspension is no longer appropriate; provided that the
period during which the availability of the Shelf Registration Statement and any Prospectus
is suspended (the “Deferral Period”), without the Company incurring any obligation to pay
Additional Interest pursuant to Section 2(d), shall not exceed one hundred and twenty
(120) days in the aggregate in any twelve (12) month period.

(c) Each Holder of Registrable Securities agrees that upon receipt of any Deferral
Notice from the Company, such Holder shall forthwith discontinue (and cause any placement or
sales agent or underwriters acting on their behalf to discontinue) the disposition of
Registrable Securities pursuant to the registration statement applicable to such Registrable
Securities until such Holder (i) shall have received copies of such amended or supplemented
Prospectus and, if so directed by the Company, such Holder shall deliver to the Company (at
the Company’s expense) all copies, other than permanent file copies, then in such Holder’s
possession of the Prospectus covering such Registrable Securities at the time of receipt of
such notice or (ii) shall have received notice from the Company that the disposition of
Registrable Securities pursuant to the Shelf Registration may continue.

(d) The Company may require each Holder of Registrable Securities as to which any
registration pursuant to Section 2(a) is being effected to furnish to the Company such
information regarding such Holder and such Holder’s intended method of distribution of such
Registrable Securities as the Company may from time to time reasonably request in writing,
but only to the extent that such information is required in order to comply with the
Securities Act or other applicable law. Each such Holder agrees to notify the Company as
promptly as practicable of any inaccuracy or change in information previously furnished by
such Holder to the Company or of the occurrence of any event in either case as a result of
which any Prospectus relating to such registration contains or would contain an untrue
statement of a material fact regarding such Holder or such Holder’s intended method of
disposition of such Registrable Securities or omits to state any material fact regarding
such Holder or such Holder’s intended method of disposition of such Registrable Securities
required to be stated therein or necessary to make the statements therein not misleading,
and promptly to furnish to the Company any additional information required to correct and
update any previously furnished information or required so that such Prospectus shall not
contain, with respect to such Holder or the disposition of such Registrable Securities, an
untrue statement of a material fact or omit to state a material fact required to be stated
therein or necessary to make the statements therein not misleading.

(e) The Company shall comply with all applicable rules and regulations of the
Commission and make generally available to its securityholders earning statements (which
need not be audited) satisfying the provisions of Section 11(a) of the Securities Act and
Rule 158 thereunder (or any similar rule promulgated under the Securities Act) no later than
(i) 40 days after the end of any 12-month period (or 60 days after the end of any 12-month
period if such period is a fiscal year) if the Company is at such time an “accelerated
filer” and (ii) 45 days after the end of any 12-month period (or 90 days after the end of
any 12-month period if such period is a fiscal year) if the Company is not an “accelerated
filer” commencing on the first day of the first fiscal quarter of the Company commencing
after the effective date of the Shelf Registration Statement, which statements shall cover
said 12-month periods.

(f) The Company shall provide a CUSIP number for all Registrable Securities covered by
the Shelf Registration Statement not later than the effective date of such Shelf
Registration Statement and provide the Trustee for the Notes and the transfer agent for the
Shares with printed certificates for the Registrable Securities that are in a form eligible
for deposit with The Depository Trust Company.

(g) The Company shall use its reasonable efforts to provide such information as is
required for any filings required to be made with the National Association of Securities
Dealers, Inc.

(h) Until the expiration of the Effectiveness Period, the Company will not, and will
not permit any of its “affiliates” (as defined in Rule 144) to, resell any of the Securities
that have been reacquired by any of them except pursuant to an effective registration
statement under the Securities Act.

(i) The Company shall cause the Indenture to be qualified under the Trust Indenture Act
in a timely manner.

(j) The Company shall enter into such customary agreements and take all such other
necessary and lawful actions in connection therewith (including those requested by the
Majority Holders of the Registrable Securities being sold) in order to expedite or
facilitate disposition of such Registrable Securities.

4. Holder’s Obligations.

Each Holder agrees, by acquisition of the Registrable Securities, that no Holder of
Registrable Securities shall be entitled to sell any of such Registrable Securities pursuant to the
Shelf Registration Statement or to receive a Prospectus relating thereto, unless such Holder has
furnished the Company with a Notice and Questionnaire as required pursuant to Section 2(c) hereof
(including the information required to be included in such Notice and Questionnaire) and the
information set forth in the next sentence. Each Notice Holder agrees promptly to furnish to the
Company all information required to be disclosed in order to make the information previously
furnished to the Company by such Notice Holder not misleading and any other information regarding
such Notice Holder and the distribution of such Registrable Securities as may be required to be
disclosed in the Shelf Registration Statement under applicable law or pursuant to Commission
comments. Each Holder further agrees not to sell any Registrable Securities pursuant to the Shelf
Registration Statement without delivering, or causing to be delivered, a Prospectus to the
purchaser thereof and, following termination of the Effective Period, to notify the Company, within
10 Business Days of a request by the Company, of the amount of Registrable Securities sold pursuant
to the Shelf Registration Statement and, in the absence of a response, the Company may assume that
all of the Holder’s Registrable Securities were so sold.

5. Registration Expenses.

The Company agrees to bear and to pay or cause to be paid promptly upon request being made
therefor all expenses incident to the Company’s performance of or compliance with this Agreement,
including, but not limited to, (a) all Commission and any NASD registration and filing fees and
expenses, (b) all fees and expenses in connection with the qualification of the Securities for
offering and sale under the State securities and Blue Sky laws referred to in Section 3(a)(v)
hereof, including reasonable fees and disbursements of one counsel for the placement agent or
underwriters, if any, in connection with such qualifications, (c) all expenses relating to the
preparation, printing, distribution and reproduction of the Shelf Registration Statement, the
related Prospectus, each amendment or supplement to each of the foregoing, the certificates
representing the Securities and all other documents relating hereto, (d) fees and expenses of the
Trustee under the Indenture, any escrow agent or custodian, and of the registrar and transfer agent
for the Shares, (e) fees, disbursements and expenses of counsel and independent certified public
accountants of the Company (including the expenses of any reports required by the Securities Act or
the rules and regulations thereunder to be included or incorporated by reference in the Shelf
Registration Statement or “cold comfort” letters required by or incident to such performance and
compliance) and (f) reasonable fees, disbursements and expenses of one counsel for the Holders of
Registrable Securities retained in connection with the Shelf Registration Statement, as selected by
the Company (unless reasonably objected to by the Majority Holders of the Registrable Securities
being registered, in which case the Majority Holders shall select such counsel for the
Holders)(“Special Counsel”), and fees, expenses and disbursements of any other Persons, including
special experts, retained by the Company in connection with such registration (collectively, the
“Registration Expenses”). To the extent that any Registration Expenses are incurred, assumed or
paid by any Holder of Registrable Securities or any underwriter or placement agent therefor, the
Company shall reimburse such Person for the full amount of the Registration Expenses so incurred,
assumed or paid promptly after receipt of a documented request therefor. Notwithstanding the
foregoing, the Holders of the Registrable Securities being registered shall pay all underwriting
discounts and commissions and placement agent fees and commissions attributable to the sale of such
Registrable Securities and the fees and disbursements of any counsel or other advisors or experts
retained by such Holders (severally or jointly), other than the counsel and experts specifically
referred to above.

6. Indemnification.

(a) The Company agrees to indemnify and hold harmless each Holder (including, without
limitation, the Initial Purchasers), the directors, officers, employees and Affiliates of
the Initial Purchasers and each person who controls such Holder within the meaning of either
the Act or the Exchange Act against any and all losses, claims, damages or liabilities,
joint or several, to which they or any of them may become subject under the Act, the
Exchange Act or other federal or state statutory law or regulation, at common law or
otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect
thereof) arise out of or are based upon any untrue statement or alleged untrue statement of
a material fact contained in any such Registration Statement or any prospectus forming part
thereof or in any amendment or supplement thereto, or arise out of or are based upon the
omission or alleged omission to state therein a material fact required to be stated therein
or necessary to make the statements therein, in the light of the circumstances under which
they were made, not misleading, and agrees to reimburse each such indemnified party, as
incurred, for any legal or other expenses reasonably incurred by it in connection with
investigating or defending any such loss, claim, damage, liability or action; provided,
however, that the Company will not be liable in any such case to the extent that any such
loss, claim, damage or liability arises out of or is based upon any such untrue statement or
alleged untrue statement or omission or alleged omission from any such document, in reliance
upon and in conformity with written information provided by a Holder in its most recent
Notice and Questionnaire; provided further, that with respect to any untrue statement or
omission of material fact from any related preliminary prospectus, the indemnity agreement
contained in this Section 6(a) shall not inure to the benefit of any Holder from whom the
Person asserting any such loss, claim, damage or liability purchased the securities
concerned, to the extent that any such loss, claim, damage or liability of such Holder
occurs under the circumstance that (y) the untrue statement or omission of a material fact
from the related preliminary prospectus was corrected in the final prospectus unless, in
either case, such failure to deliver the final Prospectus was a result of non-compliance by
the Company with Section 3 and (z) there was not sent or given to such Person, at or prior
to the written confirmation of the sale of such securities to such Person, a copy of the
final prospectus. This indemnity agreement will be in addition to any liability that the
Company may otherwise have.

(b) Each Holder agrees to indemnify and hold harmless the Company, each of its
directors, each of its officers, and each person, if any, who controls the Company within
the meaning of either the Act or the Exchange Act, against any and all losses, claims,
damages or liabilities, joint or several, to which the Company may become subject under the
Act, the Exchange Act or other federal or state statutory law or regulation, at common law
or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect
thereof) arise out of or are based upon any untrue statement or alleged untrue statement of
a material fact contained in any such Registration Statement or any prospectus forming part
thereof or in any amendment or supplement thereto, or arise out of or are based upon the
omission or alleged omission to state therein a material fact required to be stated therein
or necessary to make the statements therein, in the light of the circumstances under which
they were made, not misleading, but in each case only to the extent that the untrue
statement or alleged untrue statement or omission or alleged omission was made in reliance
upon and in conformity with any information furnished to the Company by such Holder in its
most recent Notice and Questionnaire, and agrees to reimburse the Company, as incurred, for
any legal or other expenses reasonably incurred by it in connection with investigating or
defending any such loss, claim, damage, liability or action provided, however, that no such
Holder shall be liable for any indemnity claims hereunder in excess of the amount of net
proceeds received by such Holder from the sale of Securities pursuant to such Shelf
Registration Statement. This indemnity agreement will be in addition to any liability which
any such Holder may otherwise have.

(c) Promptly after receipt by an indemnified party under this Section 6 of notice of
the commencement of any action, such indemnified party will, if a claim in respect thereof
is to be made against the indemnifying party under this Section 6, notify the indemnifying
party in writing of the commencement thereof; but the failure so to notify the indemnifying
party (i) will not relieve it from liability under paragraph (a) or (b) above unless and to
the extent it has been materially prejudiced through the forfeiture by the indemnifying
party of substantial rights and defenses and (ii) will not, in any event, relieve the
indemnifying party from any obligations to any indemnified party other than the
indemnification obligation provided in paragraph (a) or (b). If any action shall be brought
against an indemnified party and it shall have notified the indemnifying party thereof, the
indemnifying party shall be entitled to appoint counsel (including local counsel) of the
indemnifying party’s choice at the indemnifying party’s expense to represent the indemnified
party in any action for which indemnification is sought (in which case the indemnifying
party shall not thereafter be responsible for the fees and expenses of any separate counsel,
other than local counsel if not appointed by the indemnifying party, retained by the
indemnified party or parties except as set forth below); provided, however, that such
counsel shall be reasonably satisfactory to the indemnified party. Notwithstanding the
indemnifying party’s election to appoint counsel (including local counsel) to represent the
indemnified party in an action, the indemnified party shall have the right to employ
separate counsel (including local counsel), and the indemnifying party shall bear the
reasonable fees, costs and expenses of such separate counsel if (i) the use of counsel
chosen by the indemnifying party to represent the indemnified party would present such
counsel with a conflict of interest; (ii) the actual or potential defendants in, or targets
of, any such action include both the indemnified party and the indemnifying party and the
indemnified party shall have reasonably concluded that there may be legal defenses available
to it and/or other indemnified parties that are different from or additional to those
available to the indemnifying party; (iii) the indemnifying party shall not have employed
counsel reasonably satisfactory to the indemnified party to represent the indemnified party
within a reasonable time after notice of the institution of such action; or (iv) the
indemnifying party shall authorize the indemnified party to employ separate counsel at the
expense of the indemnifying party. An indemnifying party will not, without the prior
written consent of the indemnified parties, settle or compromise or consent to the entry of
any judgment with respect to any pending or threatened claim, action, suit or proceeding in
respect of which indemnification or contribution may be sought hereunder (whether or not the
indemnified parties are actual or potential parties to such claim or action) unless such
settlement, compromise or consent includes an unconditional release of each indemnified
party from all liability arising out of such claim, action, suit or proceeding and does not
include an admission of fault, culpability or a failure to act, by or on behalf of such
indemnified party.

(d) The provisions of this Section 6 and Section 7 shall remain in full force and
effect, regardless of any investigation made by or on behalf of any Holder, the Company, or
any of the indemnified Persons referred to in this Section 6 and Section 7, and shall
survive the sale by a Holder of securities covered by the Shelf Registration Statement.

7. Contribution.

If the indemnification provided for in Section 6 is unavailable or insufficient to hold
harmless an indemnified party under Section 6(a) or 6(b), then each indemnifying party shall, in
lieu of indemnifying such indemnified party, contribute to the amount paid or payable by such
indemnified party as a result of such loss, claim, damage or liability, or action in respect
thereof, (i) in such proportion as shall be appropriate to reflect the relative benefits received
by the Company from the offering and sale of the Notes, on the one hand, and a Holder with respect
to the sale by such Holder of Securities, on the other, or (ii) if the allocation provided by
clause (i) above is not permitted by applicable law, in such proportion as is appropriate to
reflect not only the relative benefits referred to in clause (i) above but also the relative fault
of the Company and such Holder on the other with respect to the statements or omissions that
resulted in such loss, claim, damage or liability, or action in respect thereof, as well as any
other relevant equitable considerations. The relative benefits received by the Company on the one
hand and a Holder on the other with respect to such offering and such sale shall be deemed to be in
the same proportion as the total net proceeds from the offering of the Notes (excluding discounts
and commissions, but before deducting expenses) received by or on behalf of the Company, on the one
hand, and the total net proceeds (excluding discounts and commissions, but before deducting
expenses) received by such Holder upon a resale of the Securities, on the other, bear to the total
gross proceeds from the sale all Securities pursuant to the Shelf Registration Statement in the
offering of the Securities from which the contribution claim arises. The relative fault shall be
determined by reference to, among other things, whether the untrue or alleged untrue statement of a
material fact or the omission or alleged omission to state a material fact relates to the Company
or information supplied by the Company on the one hand or to any information contained in the
relevant Notice and Questionnaire supplied by such Holder on the other, the intent of the parties
and their relative knowledge, access to information and opportunity to correct or prevent such
untrue statement or omission. The parties hereto agree that it would not be just and equitable if
contributions pursuant to this Section 7 were to be determined by pro rata allocation or by any
other method of allocation that does not take into account the equitable considerations referred to
herein. The amount paid or payable by an indemnified party as a result of the loss, claim, damage
or liability, or action in respect thereof, referred to above in this Section 7 shall be deemed to
include, for purposes of this Section 7, any legal or other expenses reasonably incurred by such
indemnified party in connection with investigating or defending or preparing to defend any such
action or claim. Notwithstanding the provisions of this Section 7, an indemnifying party that is a
Holder of Securities shall not be required to contribute any amount in excess of the amount by
which the total price at which the Securities sold by such indemnifying party to any purchaser
exceeds the amount of any damages which such indemnifying party has otherwise paid or become liable
to pay by reason of any untrue or alleged untrue statement or omission or alleged omission. No
person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the
Securities Act) shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation.

8. Rule 144A and Rule 144.

So long as any Registrable Securities remain outstanding, the Company shall use its reasonable
efforts to file the reports required to be filed by it under Rule 144A(d)(4) under the Securities
Act and the Exchange Act in a timely manner and, if at any time the Company is not required to file
such reports, it will, upon the written request of any Holder of Restricted Securities, make
publicly available other information so long as necessary to permit sales of such Holder’s
securities pursuant to Rules 144 and 144A. The Company covenants that it will take such further
action as any Holder of Restricted Securities may reasonably request, all to the extent required
from time to time to enable such Holder to sell Registrable Securities without registration under
the Securities Act within the limitation of the exemptions provided by Rules 144 and 144A
(including, without limitation, the requirements of Rule 144A(d)(4)). Upon the written request of
any Holder of Registrable Securities, the Company shall deliver to such Holder a written statement
as to whether it has complied with such requirements. Notwithstanding the foregoing, nothing in
this Section 8 shall be deemed to require the Company to register any of its securities pursuant to
the Exchange Act.

9. Miscellaneous.

(a) Amendments and Waivers. The provisions of this Agreement may not be amended,
modified or supplemented, and waivers or consents to departures from the provisions hereof may not
be given, unless the Company has obtained the written consent of the Majority Holders.
Notwithstanding the foregoing, a waiver or consent to depart from the provisions hereof with
respect to a matter that relates exclusively to the rights of Holders whose Securities are being
sold pursuant to the Shelf Registration Statement and that does not directly or indirectly affect
the rights of other Holders may be given by Holders of a majority in aggregate amount of the
Securities being sold by such Holders pursuant to the Shelf Registration Statement.

(b) Notices. All notices and other communications provided for or permitted hereunder
shall be made in writing by hand-delivery, first-class mail, telecopier or air courier guaranteeing
next-day delivery:

(1) If to the Company, initially at the address set forth in the Purchase
Agreement;

(2) If to the Initial Purchasers, initially at the address of the
representative set forth in the Purchase Agreement; and

(3) If to a Holder, to the address of such Holder set forth in the security
register, the Notice and Questionnaire or other records of the Company.

All such notices and communications shall be deemed to have been duly given: when delivered by
hand, if personally delivered; one business day after being delivered to a next-day air courier;
five business days after being deposited in the mail; and when receipt is acknowledged by the
recipient’s telecopier machine, if sent by telecopier.

(c) Successors and Assigns. This Agreement shall be binding upon the Company and each
of its successors and assigns.

(d) Counterparts. This Agreement may be executed in any number of counterparts (which
may be delivered in original form or by telecopier) and by the parties hereto in separate
counterparts, each of which when so executed shall be deemed to be an original and all of which
taken together shall constitute one and the same agreement.

(e) Definition of Terms. For purposes of this Agreement, (a) the term “business day”
means any day on which the New York Stock Exchange, Inc. is open for trading, (b) the term
“subsidiary” has the meaning set forth in Rule 405 under the Securities Act and (c) except where
otherwise expressly provided, the term “affiliate” has the meaning set forth in Rule 405 under the
Securities Act.

(f) Headings. The headings in this Agreement are for convenience of reference only
and shall not limit or otherwise affect the meaning hereof.

(g) Governing Law. This Agreement shall be governed by and construed in accordance
with the laws of the State of New York.

(h) Remedies. In the event of a breach by the Company or by any Holder of any of
their respective obligations under this Agreement, each Holder or the Company, as the case may be,
in addition to being entitled to exercise all rights granted by law, including recovery of damages
(other than the recovery of damages for a breach by the Company of its obligations under Section 3
hereof for which Additional Interest have been paid pursuant to Section 2 hereof), will be entitled
to specific performance of its rights under this Agreement. The Company and each Holder agree that
monetary damages would not be adequate compensation for any loss incurred by reason of a breach by
it of any of the provisions of this Agreement and hereby further agree that, in the event of any
action for specific performance in respect of such breach, it shall waive the defense that a remedy
at law would be adequate.

(i) No Inconsistent Agreements. The Company represents, warrants and agrees that
(i) it has not entered into, shall not, on or after the date of this Agreement, enter into any
agreement that is inconsistent with the rights granted to the Holders in this Agreement or
otherwise conflicts with the provisions hereof, (ii) there are no contracts, commitments,
agreements, arrangements, understandings or undertakings of any kind to which the Company is a
party, or by which it is bound, granting to any person the right to require either the Company to
file a registration statement under the Securities Act with respect to any securities of the
Company or requiring the Company to include such securities with the Securities registered pursuant
to any registration statement and (iii) without limiting the generality of the foregoing, without
the written consent of the Majority Holders, it shall not grant to any Person the right to request
