ARTICLE 2

The Securities

     Section 2.01 . Form and Dating. The Securities and the Trustee’s certificate of
authentication shall be substantially in the respective forms set forth in Exhibit A, which Exhibit
is incorporated in and made part of this Indenture. The Securities may have notations, legends or
endorsements required by law, stock exchange rule or usage. The Company shall provide any such
notations, legends or endorsements to the Trustee in writing. Each Security shall be dated the
date of its authentication. The Securities are being offered and sold by the Company pursuant to a
Purchase Agreement, dated March 8, 2006 (the “Purchase Agreement”), between the Company and the
Initial Purchaser, in transactions exempt from, or not subject to, the registration requirements of
the Securities Act.

     (a) Restricted Global Securities. All of the Securities are initially being offered and sold
to qualified institutional buyers as defined in Rule 144A (collectively, “QIBs” or individually,
each a “QIB”) in reliance on Rule 144A

11

 

under the Securities Act and shall be issued initially in the form of one or more Restricted
Global Securities, which shall be deposited on behalf of the purchasers of the Securities
represented thereby with the Trustee, at its Corporate Trust Office, as custodian for the
depositary, The Depository Trust Company (“DTC”) (such depositary, or any successor thereto, being
hereinafter referred to as the “Depositary”), and registered in the name of its nominee, Cede &
Co., duly executed by the Company and authenticated by the Trustee as hereinafter provided. The
aggregate Principal Amount of the Restricted Global Securities may from time to time be increased
or decreased by adjustments made on the records of the Securities Custodian as hereinafter
provided, subject in each case to compliance with the Applicable Procedures.

     (b) Global Securities in General. Each Global Security shall represent such of the
outstanding Securities as shall be specified therein and each shall provide that it shall represent
the aggregate amount of outstanding Securities from time to time endorsed thereon and that the
aggregate amount of outstanding Securities represented thereby may from time to time be reduced or
increased, as appropriate, to reflect exchanges, redemptions, purchases or conversions of such
Securities. Any adjustment of the aggregate Principal Amount of a Global Security to reflect the
amount of any increase or decrease in the amount of outstanding Securities represented thereby
shall be made by the Trustee in accordance with instructions given by the Holder thereof as
required by Section 2.12 and shall be made on the records of the Trustee and the Depositary.

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

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

“UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF THE
DEPOSITORY TRUST COMPANY TO THE COMPANY OR ITS AGENT FOR REGISTRATION OF
TRANSFER, EXCHANGE OR

12

 

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

     Section 2.02 . Execution and Authentication. An Officer shall sign the Securities for the
Company by manual or facsimile signature attested by the manual or facsimile signature of the
Secretary, an Assistant Secretary or a Vice President of the Company. Typographic and other minor
errors or defects in any such facsimile signature shall not affect the validity or enforceability
of any Security which has been authenticated and delivered by the Trustee.

     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 signs the
certificate of authentication on the Security. The signature shall be conclusive evidence that the
Security has been authenticated under this Indenture.

13

 

     The Trustee shall authenticate and make available for delivery Securities for original issue
in the aggregate Principal Amount of $200,000,000 (or up to $230,000,000 to the extent the Initial
Purchaser exercises its over-allotment option) upon receipt of a written order or orders of the
Company signed by an Officer of the Company (a “Company Order”). The Company Order shall specify
the amount of Securities to be authenticated, shall provide that all such Securities will be
represented by a Global Security and the date on which each original issue of Securities is to be
authenticated. The aggregate Principal Amount of Securities outstanding at any time may not exceed
$200,000,000 (or $230,000,000 if the Initial Purchaser exercises its over-allotment option in full)
except as provided in Section 2.07.

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

     The Securities shall be issuable only in registered form without coupons and only in
denominations of $1,000 Principal Amount and any integral multiple thereof.

     Section 2.03 . Registrar, Paying Agent and Conversion Agent. The Company shall maintain one
or more offices or agencies where Securities may be presented for registration of transfer or for
exchange (each, a “Registrar”), one or more offices or agencies where Securities may be presented
for payment (each, a “Paying Agent”), one or more offices or agencies where Securities may be
presented for conversion (each, a “Conversion Agent”) and one or more offices or agencies where
notices and demands to or upon the Company in respect of the Securities and this Indenture may be
served. The Company will at all times maintain a Paying Agent, Conversion Agent, Registrar and an
office or agency where notices and demands to or upon the Company in respect of the Securities and
this Indenture may be served in The Borough of Manhattan, The City of New York. One of the
Registrars (the “Primary Registrar”) shall keep a register of the Securities and of their transfer
and exchange.

     The Company shall enter into an appropriate agency agreement with any Agent not a party to
this Indenture. The agreement shall implement the provisions of this Indenture that relate to such
Agent. The Company shall notify the Trustee of the name and address of any Agent not a party to
this Indenture. If the Company fails to maintain a Registrar, Paying Agent, Conversion Agent or
agent for service of notices and demands in any place required by this Indenture, or fails to give
the foregoing notice, the Trustee shall act as such. The Company or any Affiliate of the Company
may act as Paying Agent (except for the purposes of Section 5.01 and Article 9).

14

 

     The Company hereby initially designates the Trustee as Paying Agent, Registrar, Securities
Custodian and Conversion Agent, and each of the Corporate Trust Office of the Trustee and the
office or agency of the U.S. Bank Trust National Association, an Affiliate, in The Borough of
Manhattan, The City of New York (located at U.S. Bank Trust National Association, Mail Station:
EX-NY-WALL, 100 Wall Street, Suite 1600, New York, NY 10005, Attention: Corporate Trust Services),
one such office or agency of the Company for each of the aforesaid purposes.

     Section 2.04 . Paying Agent to Hold Money in Trust. Prior to 1:00 p.m., New York City time,
on each date on which the Principal Amount of or interest, if any, on any Securities is due and
payable, the Company shall deposit with a Paying Agent a sum sufficient to pay such Principal
Amount or interest, if any, so becoming due. A Paying Agent shall hold in trust for the benefit of
Securityholders or the Trustee all money held by the Paying Agent for the payment of Principal
Amount of or interest, if any, on the Securities, and shall notify the Trustee of any default by
the Company (or any other obligor on the Securities) in making any such payment. If the Company or
an Affiliate of the Company acts as Paying Agent, it shall, before 1:00 p.m., New York City time,
on each date on which a payment of the Principal Amount of or interest on any Securities is due and
payable, segregate the money and hold it as a separate trust fund. The Company at any time may
require a Paying Agent to pay all money held by it to the Trustee, and the Trustee may at any time
during the continuance of any default, upon written request to a Paying Agent, require such Paying
Agent to pay forthwith to the Trustee all sums so held in trust by such Paying Agent. Upon doing
so, the Paying Agent (other than the Company) shall have no further liability for the money.

     Section 2.05 . Securityholder Lists. The Trustee shall preserve in as current a form as is
reasonably practicable the most recent list available to it of the names and addresses of
Securityholders. If the Trustee is not the Primary Registrar, the Company shall furnish to the
Trustee on or before each semiannual interest payment date, and at such other times as the Trustee
may request in writing, a list in such form and as of such date as the Trustee may reasonably
require of the names and addresses of Securityholders.

     Section 2.06 . Transfer and Exchange. Subject to compliance with any applicable additional
requirements contained in Section 2.12, when a Security is presented to a Registrar with a request
to register a transfer thereof or to exchange such Security for an equal Principal Amount of
Securities of other authorized denominations, the Registrar shall register the transfer or make the
exchange as requested if its requirements for such transactions are met; provided, however, that
every Security presented or surrendered for registration of transfer or exchange shall be duly
endorsed or accompanied by an assignment form in the form included in Exhibit A, and in form
satisfactory to the Registrar duly executed by the Holder thereof or its attorney duly authorized
in writing. To permit registration of transfers and exchanges, upon surrender of any Security for

15

 

registration of transfer or exchange at an office or agency maintained pursuant to Section
2.03, the Company shall execute and the Trustee shall authenticate Securities of a like aggregate
Principal Amount at the Registrar’s request. Any exchange or transfer shall be without charge,
except that the Company or the Registrar may require payment of a sum sufficient to cover any tax
or other governmental charge that may be imposed in relation thereto, and provided, that this
sentence shall not apply to any exchange pursuant to Section 2.10, Section 2.12(a), Section 3.06,
Section 3.08(d), Section 4.02(e) or Section 10.05 not involving any transfer.

     Neither the Company, any Registrar nor the Trustee shall be required to (a) register the
transfer of or exchange any Security for a period of 15 days before selecting Securities to be
redeemed; (b) register the transfer of or exchange any Security during the period beginning at the
opening of business 15 days before the mailing of a notice of redemption of Securities selected for
redemption and ending at 5:00 p.m. New York City time on the day of the mailing; or (c) register
the transfer of or exchange any Security that has been selected for redemption or for which the
Holder has delivered, and not validly withdrawn, a Repurchase Notice or Fundamental Change
Repurchase Notice, except, in the case of a partial redemption, purchase or repurchase, that
portion of the Securities not being redeemed, purchase or repurchased.

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

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

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

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

16

 

     Section 2.07 . Replacement Securities. If any mutilated Security is surrendered to the
Company, a Registrar or the Trustee, or the Company, a Registrar and the Trustee receive evidence
to their satisfaction of the destruction, loss or theft of any Security, and there is delivered to
the Company, the applicable Registrar and the Trustee such security or indemnity as will be
required by them to save each of them harmless, then, in the absence of notice to the Company, such
Registrar or the Trustee that such Security has been acquired by a protected purchaser, the Company
shall execute, and upon its written request the Trustee shall authenticate and deliver, in exchange
for any such mutilated Security or in lieu of any such destroyed, lost or stolen Security, a 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 or is about to
become due and payable, or is about to be redeemed or purchased by the Company pursuant to Article
3, the Company in its discretion may, instead of issuing a new Security, pay, redeem or purchase
such Security, as the case may be.

     Upon the issuance of any new Securities under this Section 2.07, the Company may require the
payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in
relation thereto and any other reasonable expenses (including the reasonable fees and expenses of
the Trustee or the Registrar) in connection therewith.

     Every new Security issued pursuant to this Section 2.07 in lieu of any mutilated, destroyed,
lost or stolen Security shall constitute an original additional contractual obligation of the
Company, whether or not the mutilated, destroyed, lost or stolen Security shall be at any time
enforceable by anyone, and shall be entitled to all benefits of this Indenture equally and
proportionately with any and all other Securities duly issued hereunder.

     The provisions of this Section 2.07 are (to the extent lawful) exclusive and shall preclude
(to the extent lawful) all other rights and remedies with respect to the replacement or payment of
mutilated, destroyed, lost or stolen Securities.

     Section 2.08 . Outstanding Securities. Securities outstanding at any time are all Securities
authenticated by the Trustee, except for those canceled by it, those converted pursuant to Article
4, those delivered to it for cancellation or surrendered for transfer or exchange and those
described in this Section 2.08 as not outstanding.

     If a Security is replaced pursuant to Section 2.07, it ceases to be outstanding unless the
Company receives proof satisfactory to it that the replaced Security is held by a protected
purchaser.

     If a Paying Agent holds at 1:00 p.m., New York City time, on the Final Maturity Date Cash
sufficient to pay the Principal Amount of the Securities

17

 

payable on that date, then on and after the Final Maturity Date, such Securities shall cease
to be outstanding.

     Subject to the restrictions contained in Section 2.09, a Security does not cease to be
outstanding because the Company or an Affiliate of the Company holds the Security.

     Section 2.09 . Treasury Securities.

     (a) In determining whether the Holders of the required Principal Amount of Securities have
concurred in any notice, direction, waiver or consent, Securities owned by the Company or any other
obligor on the Securities or by any Affiliate of the Company or of such other obligor shall be
disregarded, except that, for purposes of determining whether the Trustee shall be protected in
relying on any such notice, direction, waiver or consent, only Securities which a Trust Officer of
the Trustee actually knows are so owned shall be so disregarded. Securities so owned which have
been pledged in good faith shall not be disregarded if the pledgee establishes to the satisfaction
of the Trustee the pledgee’s right so to act with respect to the Securities and that the pledgee is
not the Company or any other obligor on the Securities or any Affiliate of the Company or of such
other obligor.

     (b) Any Securities or shares of Common Stock issued upon the conversion of Securities that are
purchased or owned by the Company or any Affiliate thereof may not be resold by the Company or such
Affiliate unless registered under the Securities Act or resold pursuant to an exemption from the
registration requirements of the Securities Act in a transaction that results in such Securities or
shares of Common Stock, as the case may be, no longer being “restricted securities” (as defined
under Rule 144).

     Section 2.10 . Temporary Securities. Until definitive Securities are ready for delivery, the
Company may prepare and execute, and, upon receipt of a Company Order, the Trustee shall
authenticate and deliver, temporary Securities. Temporary Securities shall be substantially in the
form of definitive Securities but may have variations that the Company with the consent of the
Trustee considers appropriate for temporary Securities. Without unreasonable delay, the Company
shall prepare and the Trustee shall authenticate and deliver definitive Securities in exchange for
temporary Securities.

     Section 2.11 . Cancellation. The Company at any time may deliver Securities to the Trustee
for cancellation. The Registrar, the Paying Agent and the Conversion Agent shall forward to the
Trustee or its agent any Securities surrendered to them for transfer, exchange, redemption, payment
or conversion. The Trustee and no one else shall cancel, in accordance with its standard
procedures, all Securities surrendered for transfer, exchange, redemption, payment, conversion or
cancellation and upon written request of the Company shall deliver the canceled Securities to the
Company.

18

 

     Section 2.12 . Legend, Additional Transfer and Exchange Requirements.

     (a) If Securities are issued upon the transfer, exchange or replacement of Securities subject
to restrictions on transfer and bearing the legends set forth on the forms of Securities attached
hereto as Exhibit A (collectively, the “Legend”), or if a request is made to remove the Legend on a
Security, the Securities so issued shall bear the Legend, or the Legend shall not be removed, as
the case may be, unless there is delivered to the Company and the Registrar such satisfactory
evidence, which, in the case of any transfer pursuant to Rule 144 or any other available exemption
from registration under the Securities Act, shall include an Opinion of Counsel if requested by the
Company or such Registrar, as may be reasonably required by the Company and the Registrar, that
neither the Legend nor the restrictions on transfer set forth therein are required to ensure that
transfers thereof comply with the provisions of Rule 144A or Rule 144 under the Securities Act or
that such Securities are not “restricted” within the meaning of Rule 144 under the Securities Act.
Upon (i) provision of such satisfactory evidence if requested, or (ii) written notification by the
Company to the Trustee and Registrar of the sale of such Security pursuant to a registration
statement that is effective at the time of such sale, the Trustee, at the written direction of the
Company, shall authenticate and deliver a Security that does not bear the Legend.

     (b) A Global Security may not be transferred, in whole or in part, to any Person other than
the Depositary or a nominee or any successor thereof, and no such transfer to any such other Person
may be registered; provided, that the foregoing shall not prohibit any transfer of a Security that
is issued in exchange for a Global Security but is not itself a Global Security. No transfer of a
Security to any Person shall be effective under this Indenture or the Securities unless and until
such Security has been registered in the name of such Person. Notwithstanding any other provisions
of this Indenture or the Securities, transfers of a Global Security, in whole or in part, shall be
made only in accordance with this Section 2.12.

     (c) Subject to the succeeding paragraph, every Security shall be subject to the restrictions
on transfer provided in the Legend other than a Restricted Global Security. Whenever any Transfer
Restricted Security other than a Restricted Global Security is presented or surrendered for
registration of transfer or for exchange for a Security registered in a name other than that of the
Holder, such Security must be accompanied by a certificate in substantially the form set forth in
Exhibit B, dated the date of such surrender and signed by the Holder of such Security, as to
compliance with such restrictions on transfer. The Registrar shall not be required to accept for
such registration of transfer or exchange any Security not so accompanied by a properly completed
certificate.

     (d) The restrictions imposed by the Legend upon the transferability of any Security shall
cease and terminate when such Security has been sold pursuant to an effective registration
statement under the Securities Act or transferred in compliance with Rule 144 under the Securities
Act (or any successor provision

19

 

thereto) or, if earlier, upon the expiration of the holding period applicable to sales thereof
under Rule 144(k) under the Securities Act (or any successor provision). Any Security as to which
such restrictions on transfer shall have expired in accordance with their terms or shall have
terminated may, upon a surrender of such Security for exchange to the Registrar in accordance with
the provisions of this Section 2.12 (accompanied, in the event that such restrictions on transfer
have terminated by reason of a transfer in compliance with Rule 144 or any successor provision, by,
if requested, an Opinion of Counsel reasonably acceptable to the Company and the Trustee, addressed
to the Company and the Trustee and in form acceptable to the Company and the Trustee, to the effect
that the transfer of such Security has been made in compliance with Rule 144 or such successor
provision and applicable state securities laws), be exchanged for a new Security, of like tenor and
aggregate Principal Amount, which shall not bear the restrictive Legend. The Company shall inform
the Trustee of the effective date of any registration statement registering the Securities under
the Securities Act. The Trustee shall not be liable for any action taken or omitted to be taken by
it in good faith in accordance with the aforementioned Opinion of Counsel or registration
statement.

     (e) As used in the preceding two paragraphs of this Section 2.12, the term “transfer”
encompasses any sale, pledge, transfer, hypothecation or other disposition of any Security.

     (f) The provisions of clauses (i), (ii), (iii) and (iv) below shall apply only to Global
Securities:

     (i) Notwithstanding any other provisions of this Indenture or the Securities, a
Global Security shall not be exchanged in whole or in part for a Security registered in
the name of any Person other than the Depositary or one or more nominees thereof,
provided, that a Global Security may be exchanged for Securities registered in the names
of any person designated by the Depositary in the event that (A) the Depositary has
notified the Company that it is unwilling or unable to continue as Depositary for such
Global Security or such Depositary has ceased to be a “clearing agency” registered under
the Exchange Act, and a successor Depositary is not appointed by the Company within 90
days, or (B) an Event of Default has occurred and is continuing with respect to the
Securities. Any Global Security exchanged pursuant to clause (A) above shall be so
exchanged in whole and not in part, and any Global Security exchanged pursuant to clause
(B) above may be exchanged in whole or from time to time in part as directed by the
Depositary. Any Security issued in exchange for a Global Security or any portion thereof
shall be a Global Security; provided, that any such Security so issued that is registered
in the name of a Person other than the Depositary or a nominee thereof shall not be a
Global Security.

20

 

     (ii) Securities issued in exchange for a Global Security or any portion thereof shall
be issued in definitive, fully-registered book-entry form, without interest coupons, shall
have an aggregate Principal Amount equal to that of such Global Security or portion
thereof to be so exchanged, shall be registered in such names and be in such authorized
denominations as the Depositary shall designate and shall bear the applicable legends
provided for herein. Any Global Security to be exchanged in whole shall be surrendered by
the Depositary to the Trustee, as Registrar. With regard to any Global Security to be
exchanged in part, either such Global Security shall be so surrendered for exchange or, if
the Trustee is acting as custodian for the Depositary or its nominee with respect to such
Global Security, the Principal Amount thereof shall be reduced, by an amount equal to the
portion thereof to be so exchanged, by means of an appropriate adjustment made on the
records of the Trustee. Upon any such surrender or adjustment, the Trustee shall
authenticate and deliver the Security issuable on such exchange to or upon the order of
the Depositary or an authorized representative thereof.

     (iii) Subject to the provisions of clause (v) below, the registered Holder 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.

     (iv) In the event of the occurrence of any of the events specified in clause (i)
above, the Company will promptly make available to the Trustee a reasonable supply of
Certificated Securities in definitive, fully registered form, without interest coupons.

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

     Section 2.13 . CUSIP Numbers. The Company in issuing the Securities may use one or more
“CUSIP” numbers (if then generally in use), and, if so, the

21

 

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

     Section 2.14 . Regular Interest. Interest will accrue on the Securities at the rate of 3%
per year during any six-month period from and including March 15 to but excluding September 15 and
from and including September 15 to but excluding March 15, commencing September 15, 2006 (provided
that the initial period with respect to the payment of interest shall commence on March 13, 2006
and run to but excluding September 15, 2006). Interest will be payable in Cash in arrears on
September 15 and March 15 of each year, beginning September 15, 2006, to the Holder of record at
the close of business on the Regular Record Date preceding such Interest Payment Date.

     Section 2.15 . Defaulted Interest. (a) Any interest (including Additional Interest) on any
Security that is payable, but is not punctually paid or duly provided for, on any Interest Payment
Date (herein called “Defaulted Interest”) shall forthwith cease to be payable to the Holder on the
relevant Regular Record Date by virtue of having been such Holder, and such Defaulted Interest may
be paid by the Company, at its election in each case, as provided in subsection (b) of this Section
2.15.

     (b) 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 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, the date of the proposed payment and the Special
Record 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 reasonably 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. The Special Record Date for the
payment of such Defaulted Interest shall be not more than 15 days and not less than 10 days prior
to the date of the proposed payment and not less than 10 days after the receipt by the Trustee of
the notice of the proposed payment. The Trustee, in the name and at the expense of the Company,
shall cause notice of the proposed payment of such Defaulted Interest and the Special Record Date
therefor to be mailed, first-class postage prepaid, to each Holder at such Holder’s address as it
appears in the register referred to in Section 2.03, not less than 10 days prior to such Special
Record Date. Notice of the

22

 

proposed payment of such Defaulted Interest and the Special Record Date therefor having been
so mailed, such Defaulted Interest shall be paid to the Persons in whose names the Securities (or
their respective predecessor Securities) are registered at the close of business on such Special
Record Date.

     (c) Subject to the foregoing and following provisions of this Article 2, 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 (if any) accrued and unpaid, and to accrue,
which were carried by such other Security.

ARTICLE 3

Redemption and Purchases

     Section 3.01 . Right to Redeem; Notice to Trustee. The Securities may be redeemed at the
election of the Company, as a whole or from time to time in part, at any time after March 15, 2011,
at the Redemption Price in Cash specified in Paragraph 6 of the form of Security attached hereto as
Exhibit A, together with accrued and unpaid interest, if any (including Additional Interest, if
any), up to, but excluding, the Redemption Date. However, if the Redemption Date falls after a
Regular Record Date and on or prior to the corresponding Interest Payment Date, the Company will
pay the full amount of accrued and unpaid interest, if any (including Additional Interest, if any),
due on such Interest Payment Date to the Holder of record at the close of business on the
corresponding Regular Record Date, and not to the Holder submitting the notes for redemption.

     If the Company elects to redeem Securities pursuant to this Section 3.01 and Paragraph 6 of
the Securities, it shall notify the Trustee at least 45 days prior to the Redemption Date, as fixed
by the Company (unless a shorter notice shall be satisfactory to the Trustee), of the Redemption
Date and the Principal Amount of Securities to be redeemed.

     Section 3.02 . Selection of Securities to Be Redeemed. If less than all of the Securities
are to be redeemed, unless the procedures of the Depositary provide otherwise, the Trustee shall,
at least 30 days but not more than 60 days prior to the Redemption Date, select the Securities to
be redeemed. The Trustee shall make the selection from the Securities outstanding and not
previously called for redemption, by lot, on a pro rata basis or in accordance with any other
method the Trustee considers fair and appropriate. Securities in denominations of $1,000 may only
be redeemed in whole. The Trustee may select for redemption portions (equal to $1,000 or any
integral multiple thereof) of the Principal Amount of Securities that have denominations larger
than $1,000. Provisions of this Indenture that apply to Securities called for redemption also
apply to portions of Securities called for redemption.

23

 

     If any Security selected for partial redemption is converted in part before termination of the
conversion right with respect to the portion of the Security so selected, the converted portion of
such Security shall be deemed to be taken from the portion selected for redemption. Securities
which have been converted during a selection of Securities to be redeemed shall be treated by the
Trustee as outstanding for the purpose of such selection.

     Section 3.03 . Notice of Redemption. At least 30 days but not more than 60 days before a
Redemption Date, the Company shall mail or cause to be mailed a notice of redemption to each Holder
of Securities to be redeemed at such Holder’s address as it appears on the Primary Registrar’s
books.

     The notice shall identify the Securities (including CUSIP numbers) to be redeemed and shall
state:

     (a) the Redemption Date;

     (b) the Redemption Price;

     (c) the then-current Conversion Rate;

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

     (e) that Securities called for redemption must be presented and surrendered to a
Paying Agent to collect the Redemption Price;

     (f) that Holders who wish to convert Securities must surrender such Securities for
conversion no later than the close of business on the Business Day immediately preceding
the Redemption Date and must satisfy the other requirements set forth in Paragraph 9 of
the Securities;

     (g) that, unless the Company defaults in making the payment of the Redemption Price,
interest on Securities called for redemption shall cease accruing on and after the
Redemption Date and subject to the provisions of Sections 3.01 and 3.04, the only
remaining right of the Holder shall be to receive payment of the Redemption Price upon
presentation and surrender to a Paying Agent of the Securities; and

     (h) if any Security is being redeemed in part, the portion of the Principal Amount of
such Security to be redeemed and that, after the Redemption Date, upon presentation and
surrender of such Security, a new Security or Securities in aggregate Principal Amount
equal to the unredeemed portion thereof will be issued.

     If any of the Securities to be redeemed is in the form of a Global Security, then the Company
shall modify such notice to the extent necessary to accord with the procedures of the Depositary
applicable to redemptions. At the Company’s

24

 

written request, which request shall (i) be irrevocable once given and (ii) set forth all
relevant information required by clauses (a) through (h) of the preceding paragraph, the Trustee
shall give the notice of redemption in the Company’s name and at the Company’s expense.

     Section 3.04 . Effect of Notice of Redemption. Once notice of redemption is mailed,
Securities called for redemption become due and payable on the Redemption Date and at the
Redemption Price stated in the notice. Upon presentation and surrender to a Paying Agent,
Securities called for redemption shall be paid in Cash at the Redemption Price. However, if the
Redemption Date falls after a Regular Record Date and on or prior to the corresponding Interest
Payment Date, the Company will pay the full amount of accrued and unpaid interest, if any
(including Additional Interest, if any), due on such Interest Payment Date to the Holder of record
at the close of business on the corresponding Regular Record Date. The Company shall make at least
10 semi-annual interest payments (including the interest payments on September 15, 2006 and March
15, 2011) in the full amount required by this Indenture on the Securities before redeeming any
Securities pursuant to this Article 3.

     Section 3.05 . Deposit of Redemption Price. Prior to 1:00 p.m., New York City time, on the
Redemption Date, the Company shall deposit with a Paying Agent (or, if the Company acts as Paying
Agent, shall segregate and hold in trust) an amount of money (in immediately available funds if
deposited on such Redemption Date) sufficient to pay the Redemption Price of all Securities to be
redeemed on that date, other than Securities or portions thereof called for redemption on that date
which have been delivered by the Company to the Trustee for cancellation or have been converted.
The Paying Agent shall as promptly as practicable return to the Company any money not required for
that purpose or, if such money is then held by the Company in trust and is not required for such
purpose, it shall be discharged from the trust.

     If a Paying Agent holds on a Redemption Date Cash sufficient to pay the Redemption Price
payable on that date, then on and after such Redemption Date, such Securities (or portions thereof,
as the case may be) shall cease to be outstanding and interest (if any) on them shall cease to
accrue, whether or not such Securities are delivered to the Paying Agent, and the rights of the
Holders in respect thereof shall terminate (other than the right to receive the Redemption Price
upon delivery of such Securities, together with any necessary endorsement) and the redeemed
Securities shall be cancelled; provided, that if such Securities are to be redeemed, notice of such
redemption has been duly given pursuant to this Indenture or provision therefor satisfactory to the
Trustee has been made.

     Section 3.06 . Securities Redeemed in Part. Upon presentation and surrender of a Security
that is redeemed in part, the Company shall execute and the Trustee shall authenticate and deliver
to the Holder, without charge, a new Security or Securities of authorized denominations as
requested by such Holder in

25

 

aggregate Principal Amount equal to the unredeemed portion of the Security surrendered.

     Section 3.07 . No Redemption of Securities Upon Occurrence of Acceleration. Notwithstanding
anything herein to the contrary, the Company will not redeem any Securities on any date if the
Principal Amount of the Securities has been accelerated, and such acceleration has not been
rescinded on or prior to the Redemption Date.

     Section 3.08 . Repurchase of Securities at the Option of Holders. (a) Optional Put. (i)
Securities shall be repurchased by the Company, at the option of the Holder thereof, on each of
March 15, 2011, March 15, 2016 and March 15, 2021 (each, a “Repurchase Date”), at a repurchase
price in Cash equal to 100% of the Principal Amount of the Securities to be repurchased plus
accrued and unpaid interest, if any (including Additional Interest, if any), to, but excluding,
such Repurchase Date (the “Repurchase Price”), subject to satisfaction by or on behalf of the
Holder of the requirements set forth in Section 3.08(a)(iii), provided, however, that any such
accrued and unpaid interest, if any (including Additional Interest, if any), will be paid not to
the Holder submitting the Security for repurchase on the relevant Repurchase Date but instead to
the Holder of record at the close of business on the corresponding Record Date.

     (ii) No later than 20 Business Days prior to each Repurchase Date, the Company shall
mail a written notice of the repurchase right under Section 3.08(a)(i) (a “Purchase
Offer”) by first class mail to the Trustee and to each Holder (and to beneficial owners as
required by applicable law). The notice shall include a form of notice to be completed by
the Holder and returned to the Company in the event that the Holder elects such right to
such repurchase (the “Repurchase Notice”) and shall briefly state, as applicable:

     (A) the date by which the Repurchase Notice must be delivered to the Paying
Agent in order for a Holder to exercise the repurchase right;

     (B) the Repurchase Date;

     (C) the Repurchase Price;

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

     (E) the Conversion Rate;

     (F) that the Securities as to which a Repurchase Notice has been given may
be converted if they are otherwise convertible pursuant to Article 4 only if the
Repurchase Notice

26

 

has been withdrawn in accordance with the terms of this Indenture;

     (G) that the Securities must be surrendered to the Paying Agent to collect
payment;

     (H) that the Repurchase Price for any Security as to which a Repurchase
Notice has been duly given and not withdrawn will be paid promptly following the
later of the Repurchase Date and the time of surrender of such Security;

     (I) the procedures the Holder must follow to exercise its repurchase right
under this Section 3.08(a);

     (J) the conversion rights, if any, of the Securities;

     (K) the procedures for withdrawing a Repurchase Notice;

     (L) that, unless the Company defaults in making payment of such Repurchase
Price, interest, if any (including Additional Interest, if any), on Securities
surrendered for repurchase by the Company will cease to accrue on and after the
Repurchase Date; and

     (M) the CUSIP number(s) of the Securities.

     At the Company’s request, the Trustee shall give the Purchase Offer in the Company’s name and
at the Company’s expense; provided, however, that the Company makes such request at least three
Business Days (unless a shorter period shall be satisfactory to the Trustee) prior to the date by
which such Purchase Offer must be given to the Holder in accordance with this Section 3.08(a)(ii);
provided, further, that the text of the Purchase Offer shall be prepared by the Company.

     (iii) A Holder may exercise its right specified in Section 3.08(a)(i) upon delivery of
a properly completed Repurchase Notice to the Paying Agent at any time during the period
beginning at 9:00 a.m., New York City time, on the date that is 20 Business Days
immediately preceding the relevant Repurchase Date until 5:00 p.m., New York City time, on
the Business Day immediately preceding such Repurchase Date, stating:

     (A) the certificate number (if in certificated form) of the Security which
the Holder will deliver to be repurchased or the appropriate Depositary
procedures if Certificated Securities have not been issued;

27

 

     (B) the portion of the Principal Amount of the Security which the Holder
will deliver to be repurchased, which portion must be in Principal Amounts of
$1,000 or an integral multiple of $1,000; and

     (C) that such Security shall be repurchased by the Company as of the
Repurchase Date pursuant to the terms and conditions specified in the Securities
and in this Indenture.

     The book-entry transfer or delivery of such Security to the Paying Agent with, or at any time
after delivery of, the Repurchase Notice (together with all necessary endorsements) at the offices
of the Paying Agent shall be a condition to the receipt by the Holder of the Repurchase Price
therefor; provided, however, that such Repurchase Price shall be so paid pursuant to this Section
3.08(a) only if the Security so delivered to the Paying Agent shall conform in all respects to the
description thereof in the related Repurchase Notice.

     The Company shall repurchase from the Holder thereof, pursuant to this Section 3.08(a), a
portion of a Security, so long as the Principal Amount of such portion is $1,000 or an integral
multiple of $1,000. Provisions of this Indenture that apply to the repurchase of all of a Security
also apply to the repurchase of such portion of such Security.

     Notwithstanding anything contained herein to the contrary, any Holder delivering to the Paying
Agent the Repurchase Notice contemplated by this Section 3.08(a)(iii) shall have the right to
withdraw such Repurchase Notice at any applicable time prior to 5:00 p.m., New York City time, on
the Business Day immediately preceding the Repurchase Date by delivery of a written notice of
withdrawal to the Paying Agent in accordance with Section 3.08(b).

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

     (b) Effect of Repurchase Notice. Upon receipt by the Paying Agent of the Repurchase Notice
specified in Section 3.08(a)(iii), the Holder of the Security in respect of which such Repurchase
Notice was given shall (unless such Repurchase Notice is withdrawn as specified in the following
paragraph) thereafter be entitled to receive solely the Repurchase Price with respect to such
Security. Such Repurchase Price shall be paid to such Holder, subject to receipt of Cash by the
Paying Agent, on the later of (1) the Repurchase Date with respect to such Security (provided the
conditions in Section 3.08(a)(iii) have been satisfied) and (2) the time of book-entry transfer or
delivery of such Security to the Paying Agent by the Holder thereof in the manner required by
Section 3.08(a)(iii). Securities in respect of which a Repurchase Notice has been given by the
Holder thereof may not be converted pursuant to Article 4 on or after the date of the delivery of
such Repurchase Notice unless such Repurchase Notice has first been validly withdrawn as specified
in the following paragraph.

28

 

     A Repurchase Notice may be withdrawn by means of a written notice of withdrawal delivered to
the office of the Paying Agent in accordance with the Repurchase Notice at any time prior to 5:00
p.m., New York City time, on the Business Day immediately preceding the Repurchase Date,
specifying:

     (i) the Holder’s name and an election to withdraw such Repurchase Notice;

     (ii) the certificate number (if in certificated form) or the appropriate Depositary
procedures, if applicable, of the Security in respect of which such notice of withdrawal
is being submitted;

     (iii) the Principal Amount of the Security (which must be in an integral multiple of
$1,000) with respect to which such notice of withdrawal is being submitted; and

     (iv) the Principal Amount (which must be in an integral multiple of $1,000), if any,
of such Security which remains subject to the original Repurchase Notice and which has
been or will be delivered for repurchase by the Company.

     (c) Deposit of Repurchase Price. Prior to 1:00 p.m., New York City time, on the applicable
Repurchase Date, the Company shall deposit with the Paying Agent (or if the Company or a Subsidiary
or an Affiliate of any of them is acting as the Paying Agent, shall segregate and hold in trust as
provided in Section 2.04) an amount of Cash (in immediately available funds if deposited on such
Business Day) sufficient to pay the aggregate Repurchase Price of all the Securities or portions
thereof which are to be repurchased on such Repurchase Date.

     If the Paying Agent (other than the Company or an Affiliate of the Company) holds, in
accordance with the terms hereof, at 1:00 p.m., New York City time, on the applicable Repurchase
Date, Cash sufficient to pay the Repurchase Price of any Securities for which a Repurchase Notice
has been tendered and not withdrawn pursuant to Section 3.08(b), then, on and after such Repurchase
Date, such Securities will cease to be outstanding and interest, if any (including Additional
Interest, if any), on such Securities will cease to accrue, whether or not such Securities are
delivered to the Paying Agent, and the rights of the Holders in respect thereof shall terminate
(other than the right to receive the Repurchase Price upon delivery of such Securities, together
with any necessary endorsement) and the repurchased Securities shall be cancelled.

     (d) Securities Repurchased in Part. Any Certificated Security which is to be repurchased 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 shall authenticate and

29

 

deliver to the Holder of such Security, without 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 Security so surrendered which is not
repurchased.

     (e) Covenant to Comply with Securities Laws upon Repurchase of Securities. When complying
with the provisions of Section 3.08(a) hereof (provided, that such offer or purchase constitutes an
“issuer tender offer” for purposes of Rule 13e-4 (which term, as used herein, includes any
successor provision thereto) under the Exchange Act at the time of such offer or purchase), and
subject to any exemptions available under applicable law, the Company shall:

     (i) comply with Rule 13e-4 and Rule 14e-1 (or any successor provision) under the
Exchange Act, as applicable;

     (ii) file the related Schedule TO (or any successor schedule, form or report) under
the Exchange Act, as applicable; and

     (iii) otherwise comply with all federal and state securities laws so as to permit the
rights and obligations under Section 3.08 to be exercised in the time and in the manner
specified therein.

     To the extent that the provisions of any securities laws or regulations conflict with the
provisions of this Section 3.08, the Company’s compliance with such laws and regulations shall not
in and of itself cause a breach of its obligations under this Section 3.08.

     (f) Repayment to the Company. The Paying Agent shall return to the Company any Cash that
remains unclaimed for two years, together with interest, if any, thereon, held by it for the
payment of the Repurchase Price; provided, however, to the extent that the aggregate amount of Cash
deposited by the Company pursuant to Section 3.08(c) exceeds the aggregate Repurchase Price of the
Securities or portions thereof which the Company is obligated to repurchase on the Repurchase Date,
then, promptly after the Repurchase Date, the Paying Agent shall return any such excess to the
Company.

     (g) No Repurchase Upon Acceleration. Notwithstanding anything herein to the contrary, there
shall be no purchase of any Securities pursuant to this Section 3.08 if the Principal Amount of the
Securities has been accelerated, and such acceleration has not been rescinded, on or prior to the
Repurchase Date.

     Section 3.09 . Repurchase of Securities at Option of the Holder Upon Fundamental Change. (a)
Fundamental Change Put. (i) General. In the event any Fundamental Change shall occur,
each Holder of Securities shall have the right (the “Fundamental Change Repurchase Right”), at such
Holder’s option, to require the Company to repurchase all of such Holder’s Securities (or portions
thereof that are integral multiples of $1,000 in Principal Amount), on a date selected by the
Company (the “Fundamental Change Repurchase Date”),

30

 

which Fundamental Change Repurchase Date shall be no later than thirty five (35) calendar
days, and no earlier than twenty (20) calendar days, after the date the Fundamental Change Notice
is mailed in accordance with Section 3.09(a)(ii), and no earlier than the date such Fundamental
Change occurs, at a price, payable in Cash equal to 100% of the Principal Amount of the Securities
(or portions thereof) to be so repurchased, plus accrued and unpaid interest, if any (including
Additional Interest, if any), to, but excluding, the Fundamental Change Repurchase Date (the
"Fundamental Change Repurchase Price”), provided, however, that if a Fundamental Change Repurchase
Date falls after a Record Date and on or prior to the corresponding Interest Payment Date, the
Company will pay the full amount of accrued and unpaid interest, if any (including Additional
Interest, if any), on such Interest Payment Date to the Holder of record at the close of business
on the corresponding Record Date, which may or may not be the same Person to whom the Company will
pay the Fundamental Change Repurchase Price and the Fundamental Change Repurchase Price will be
100% of the Principal Amount of the Securities repurchased.

     (ii) Notice of Fundamental Change. No later than five Business Days after the
occurrence of a Fundamental Change the Company shall mail a written notice of such
occurrence (the “Fundamental Change Company Notice”) by first class mail to the Trustee
and to each Holder (and to beneficial owners as required by applicable law), shall publish
on the Company’s website and shall publicly announce the occurrence of such Fundamental
Change through a reputable newswire service. The notice shall include a form of notice to
be completed by the Holder in the event the Holder elects such right to repurchase
pursuant to this Section 3.09 (the “Fundamental Change Repurchase Notice”) and shall
briefly state, as applicable:

     (A) the events causing a Fundamental Change and the date of such Fundamental Change;

     (B) that the Holder has a right to require the Company to repurchase the Holder’s
Securities;

     (C) the date by which the Fundamental Change Repurchase Notice must be delivered to
the Paying Agent in order for a Holder to exercise the Fundamental Change Repurchase
Right;

     (D) the Fundamental Change Repurchase Date;

     (E) the Fundamental Change Repurchase Price;

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

     (G) the Conversion Rate applicable on the date of the Fundamental Change Company
Notice and any adjustments to the

31

 

Conversion Rate that will result from the Fundamental Change, including whether the
Company has exercised its right under Section 4.13(c);

     (H) that the Securities as to which a Fundamental Change Repurchase Notice has been
given may be converted if they are otherwise convertible pursuant to Article 4 only if the
Fundamental Change Repurchase Notice has been withdrawn in accordance with the terms of
this Indenture;

     (I) that the Securities must be surrendered to the Paying Agent to collect payment;

     (J) that the Fundamental Change Repurchase Price for any Security as to which a
Fundamental Change Repurchase Notice has been duly given and not withdrawn will be paid on
the later of the Fundamental Change Repurchase Date and the time of surrender of such
Security with the necessary endorsements;

     (K) the procedures the Holder must follow to exercise its repurchase right under this
Section 3.09(a);

     (L) the conversion rights, if any, of the Securities;

     (M) the procedures for withdrawing a Fundamental Change Repurchase Notice;

     (N) that, unless the Company defaults in making payment of such Fundamental Change
Repurchase Price, interest, if any (including Additional Interest, if any), on Securities
surrendered for repurchase by the Company will cease to accrue on and after the
Fundamental Change Repurchase Date; and

     (O) the CUSIP number(s) of the Securities.

     At the Company’s request, the Trustee shall give the Fundamental Change Company Notice in the
Company’s name and at the Company’s expense; provided, however, the Company makes such request at
least three Business Days (unless a shorter period shall be satisfactory to the Trustee) prior to
the date by which such Fundamental Change Company Notice must be given to the Holders in accordance
with this Section 3.09(a)(ii); provided, further, that the text of the Fundamental Change Company
Notice shall be prepared by the Company.

     (iii) Fundamental Change Repurchase Notice. A Holder may exercise its right
specified in Section 3.09(a)(i) upon delivery of a properly completed Fundamental Change
Repurchase Notice to the Paying Agent at any time from the opening of business on the date
of the Fundamental Change Company Notice until 5:00 p.m., New York City time, on the

32

 

Business Day immediately preceding the Fundamental Change Repurchase Date, stating:

     (A) the certificate number of the Security which the Holder will deliver to be
repurchased or the appropriate Depositary procedures if Certificated Securities have not
been issued;

     (B) the portion of the Principal Amount of the Security which the Holder will deliver
to be repurchased, which portion must be $1,000 or an integral multiple of $1,000; and

     (C) that such Security shall be repurchased on the Fundamental Change Repurchase Date
pursuant to the terms and conditions specified in the Securities and in this Indenture.

     The book-entry transfer or delivery of such Security to the Paying Agent with, or at any time
after delivery of, the Fundamental Change Repurchase Notice (together with all necessary
endorsements) at the offices of the Paying Agent shall be a condition to the receipt by the Holder
of the Fundamental Change Repurchase Price therefor; provided, however, that such Fundamental
Change Repurchase Price shall be so paid pursuant to this Section 3.09(a) only if the Security so
delivered to the Paying Agent shall conform in all respects to the description thereof set forth in
the related Fundamental Change Repurchase Notice.

     The Company shall repurchase from the Holder thereof, pursuant to this Section 3.09(a), a
portion of a Security, so long as the Principal Amount of such portion is $1,000 or an integral
multiple of $1,000. Provisions of this Indenture that apply to the repurchase of all of a Security
also apply to the repurchase of such portion of such Security.

     Notwithstanding anything contained herein to the contrary, any Holder delivering to the Paying
Agent the Fundamental Change Repurchase Notice contemplated by this Section 3.09(a)(iii) shall have
the right to withdraw such Fundamental Change Repurchase Notice at any time prior to 5:00 p.m., New
York City time, on the Business Day immediately preceding the Fundamental Change Repurchase Date by
delivery of a written notice of withdrawal to the Paying Agent in accordance with Section 3.09(b).

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

     (b) Effect of Fundamental Change Repurchase Notice. Upon receipt by the Paying Agent of the
Fundamental Change Repurchase Notice specified in Section 3.09(a)(iii), the Holder of the Security
in respect of which such Fundamental Change Repurchase Notice was given shall (unless such
Fundamental Change Repurchase Notice is withdrawn as specified in the

33

 

following paragraph) thereafter be entitled to receive solely the Fundamental Change
Repurchase Price with respect to such Security. Such Fundamental Change Repurchase Price shall be
paid to such Holder, subject to receipt of Cash by the Paying Agent, on the later of (1) the
Fundamental Change Repurchase Date with respect to such Security (provided the conditions in
Section 3.09(a)(iii) have been satisfied) and (2) the time of book-entry transfer or delivery of
such Security to the Paying Agent by the Holder thereof in the manner required by Section
3.09(a)(iii), together with the necessary endorsements. Securities in respect of which a
Fundamental Change Repurchase Notice has been given by the Holder thereof may not be converted
pursuant to Article 4 on or after the date of the delivery of such Fundamental Change Repurchase
Notice unless such Fundamental Change Repurchase Notice has first been validly withdrawn as
specified in the following paragraph.

     A Fundamental Change Repurchase Notice may be withdrawn by means of a written notice of
withdrawal delivered to the office of the Paying Agent in accordance with the Fundamental Change
Repurchase Notice at any time prior to 5:00 p.m., New York City time, on the Business Day
immediately preceding the Fundamental Change Repurchase Date, specifying:

     (i) the Holder’s name and election to withdraw such Fundamental Change Repurchase
Notice;

     (ii) the Principal Amount of the Security (which must be in an integral multiple of
$1,000) with respect to which such notice of withdrawal is being submitted;

     (iii) the certificate number (if in certificated form) or the appropriate Depository
procedures, if applicable, of the Security in respect of which such notice of withdrawal
is being submitted; and

     (iv) the Principal Amount (which must be in an integral multiple of $1,000), if any,
of such Security which remains subject to the original Fundamental Change Repurchase
Notice and which has been or will be delivered for repurchase by the Company.

     (c) Deposit of Fundamental Change Repurchase Price. Prior to 1:00 p.m., New York City time,
on the applicable Fundamental Change Repurchase Date, the Company shall deposit with the Paying
Agent (or if the Company or a Subsidiary or an Affiliate of any of them is acting as the Paying
Agent, shall segregate and hold in trust as provided in Section 2.04) an amount of Cash (in
immediately available funds if deposited on such Business Day) sufficient to pay the aggregate
Fundamental Change Repurchase Price of all the Securities or portions thereof which are to be
repurchased on such Fundamental Change Repurchase Date.

     If the Paying Agent holds, in accordance with the terms hereof, at 1:00 p.m., New York City
time, on the applicable Fundamental Change Repurchase

34

 

Date, Cash sufficient to pay the Fundamental Change Repurchase Price of any Securities for
which a Fundamental Change Repurchase Notice has been tendered and not withdrawn pursuant to
Section 3.09(b), then, on and after such Fundamental Change Repurchase Date, such Securities will
cease to be outstanding and interest, if any (including Additional Interest, if any), on such
Securities will cease to accrue, whether or not such Securities are delivered to the Paying Agent,
and the rights of the Holders in respect thereof shall terminate (other than the right to receive
the Fundamental Change Repurchase Price upon delivery of such Securities, together with necessary
endorsements) and the repurchased Securities will be cancelled.

     (d) Securities Repurchased in Part. Any Certificated Security which is to be repurchased 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 shall authenticate and deliver
to the Holder of such Security, without 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 Security so surrendered which is not repurchased.

     (e) Covenant to Comply With Securities Laws upon Repurchase of Securities. When complying
with the provisions of Section 3.09(a) hereof (provided, that such offer or purchase constitutes an
“issuer tender offer” for purposes of Rule 13e-4 (which term, as used herein, includes any
successor provision thereto) under the Exchange Act at the time of such offer or purchase), and
subject to any exemptions available under applicable law, the Company shall:

     (i) comply with Rule 13e-4 and Rule 14e-1 (or any successor provision) under the
Exchange Act, as applicable;

     (ii) file the related Schedule TO (or any successor schedule, form or report) under
the Exchange Act, as applicable; and

     (iii) otherwise comply with all federal and state securities laws so as to permit the
rights and obligations under this Section 3.09 to be exercised in the time and in the
manner specified therein.

     To the extent that the provisions of any securities laws or regulations conflict with the
provisions of this Section 3.09, the Company’s compliance with such laws and regulations shall not
in and of itself cause a breach of its obligations under this Section 3.09.

     (f) Repayment to the Company. The Paying Agent shall return to the Company any Cash that
remains unclaimed for two years, together with interest, if any, thereon, held by it for the
payment of the Fundamental Change Repurchase Price; provided, however, to the extent that the
aggregate amount of Cash

35

 

deposited by the Company pursuant to Section 3.09(c) exceeds the aggregate Fundamental Change
Repurchase Price of the Securities or portions thereof which the Company is obligated to repurchase
as of the Fundamental Change Repurchase Date then, promptly after the Fundamental Change Repurchase
Date, the Paying Agent shall return any such excess to the Company.

     (g) No Repurchase of the Securities Upon Occurrence of Acceleration. Notwithstanding anything
herein to the contrary, no Securities may be repurchased by the Company at the option of the
Holders upon a Fundamental Change if the Principal Amount of the Securities has been accelerated,
and such acceleration has not been rescinded, on or prior to the Fundamental Change Repurchase
Date.

ARTICLE 4

Conversion

     Section 4.01 . Conversion Right. (a) Subject to and upon compliance with the provisions of
this Article 4, a Holder of a Security shall have the right, at such Holder’s option, to convert
all or any portion (if the portion to be converted is $1,000 or an integral multiple of $1,000) of
such Security into the consideration described in Section 4.02(b) (the “Conversion Obligation”) at
any time prior to the close of business on the Business Day immediately preceding the Final
Maturity Date. In the case of a Security called for redemption by the Company as described in
Article 3, the conversion right in this Article 4 will expire at the close of business on the
Business Day immediately preceding the Redemption Date unless the Company defaults in payment of
the Redemption Price. The Conversion Rate shall be subject to adjustment in accordance with this
Article 4.

     Section 4.02 . Conversion Procedure; Conversion Rate; Fractional Shares; Settlement in Cash
in Lieu of Common Stock. (a) Before any Holder of a Security shall be entitled to convert the same
into Common Stock, such Holder shall, in the case of Global Securities, comply with the procedures
of the Depositary in effect at that time, and in the case of Certificated Securities, surrender
such Securities, duly endorsed to the Company or in blank, at the office of the Conversion Agent,
and shall give written notice to the Company at said office or place in the form of the Conversion
Notice attached to the Security (the “Conversion Notice”) that such Holder elects to convert the
same and shall state in writing therein the Principal Amount of Securities to be converted and the
name or names (with addresses) in which such Holder wishes the certificate or certificates for
Common Stock, if any, to be issued. Before any such conversion, a Holder also shall pay all funds
required, if any, relating to interest on the Securities, as provided in Section 4.09, and all
taxes or duties, if any, as provided in Section 4.08. A Security shall be deemed to have been
converted immediately before the close of business on the date on which all of the foregoing
requirements have been satisfied (such date, the “Conversion Date”).

36

 

     (b) Subject to the provisions of Section 4.04 and Section 4.13(c), Holders surrendering
Securities for conversion shall be entitled to receive, per Security, shares of Common Stock at a
value of 50.0000 shares of Common Stock per $1,000 Principal Amount, which represents an initial
conversion price of $20.00 per share. The Company will not issue fractional shares of Common Stock
upon conversion of Securities and instead will deliver an amount in cash equal to the value of such
fraction computed on the basis of the Closing Sale Price on the Trading Day immediately before the
Conversion Date.

     (c) From and after the close of business on the date on which the Company delivers shares of
Common Stock, to a converting Holder pursuant to this Section 4.02, the person in whose name any
certificate representing Common Stock issued pursuant to this Section 4.02 is to be registered
shall be treated as a stockholder of record of the Company, and all rights of the Holder of such
Security shall terminate, other than the right to receive the consideration deliverable upon
conversion of such Security as provided herein. A Holder of Securities is not entitled, as such,
to any rights of a holder of Common Stock until such Holder has converted its Securities into
shares of Common Stock and is deemed to be a stockholder of record of the Company, as provided in
this Section 4.02(c).

     (d) If a Holder converts more than one Security at a time, the number of full shares of Common
Stock issuable upon such conversion, if any, shall be based on the aggregate Principal Amount of
the Securities converted.

     (e) In case any Certificated Security shall be surrendered for partial conversion, the Company
shall execute and the Trustee shall, upon the written order of the Company, authenticate and
deliver to the Holder of the Security so surrendered, without charge to such Holder (subject to the
provisions of Section 4.08 hereof), a new Security or Securities in authorized denominations in an
aggregate Principal Amount equal to the unconverted portion of the surrendered Certificated
Securities.

     (f) If the last day on which a Security may be converted is a Legal Holiday in a place where a
Conversion Agent is located, the Security may be surrendered to that Conversion Agent on the next
succeeding day that is not a Legal Holiday.

     (g) Delivery of shares of Common Stock in respect of conversion to a Holder of a Security upon
conversion of such Security shall be accompanied by delivery to the Conversion Agent of
certificates for the relevant number of shares, other than in the case of Holders of Securities in
book-entry form with the Depositary, which shares shall be delivered in accordance with the
Depositary’s customary practices and delivery of Cash in respect of conversion to the Conversion
Agent or the Depositary, as applicable, for delivery to the Holder.

37

 

     (h) If a Holder exercises its right to require the Company to repurchase the Securities as
described in Article 3, such Holder may convert its Securities as provided above only if it
withdraws its applicable Repurchase Notice or Fundamental Change Repurchase Notice and converts its
Securities prior to the close of business on the Business Day immediately preceding the applicable
Repurchase Date or Fundamental Change Repurchase Date.

     Section 4.03 . Adjustment of Conversion Rate for Common Stock. The Conversion Rate shall be
adjusted from time to time as follows:

     (a) In case the Company shall, at any time or from time to time while any of the Securities
are outstanding, pay a dividend or make a distribution in shares of Common Stock to all holders of
its outstanding shares of Common Stock, then the Conversion Rate in effect at the opening of
business on the Ex-Dividend Date for such dividend or distribution shall be increased by
multiplying such Conversion Rate by a fraction:

     (i) the numerator of which shall be the sum of the number of shares of Common Stock
outstanding at the close of business on the Business Day immediately preceding the
Ex-Dividend Date for such dividend or distribution, plus the total number of shares
constituting such dividend or other distribution; and

     (ii) the denominator of which shall be the number of shares of Common Stock
outstanding at the close of business on the Business Day immediately preceding such
Ex-Dividend Date.

     Such increase shall become effective immediately after the opening of business on the
Ex-Dividend Date fixed for such dividend or distribution.

     If any dividend or distribution of the type described in this Section 4.03(a) is declared but
not so paid or made, the Conversion Rate shall again be adjusted to the Conversion Rate which would
then be in effect if such dividend or distribution had not been declared. In no event shall the
Conversion Rate be decreased pursuant to this Section 4.03(a), except as described in the
immediately preceding sentence.

     (b) In case the Company shall, at any time or from time to time while any of the Securities
are outstanding, subdivide or reclassify its outstanding shares of Common Stock into a greater
number of shares of Common Stock, then the Conversion Rate in effect at the opening of business on
the day upon which such subdivision becomes effective shall be proportionately increased, and
conversely, in case the Company shall, at any time or from time to time while any of the Securities
are outstanding, combine or reclassify its outstanding shares of Common Stock into a smaller number
of shares of Common Stock, then the Conversion Rate in effect at the opening of business on the day
upon which such combination becomes effective shall be proportionately decreased. In each such
case, the Conversion Rate shall be adjusted by multiplying such Conversion Rate

38

 

by a fraction, the numerator of which shall be the number of shares of Common Stock
outstanding immediately after giving effect to such subdivision or combination and the denominator
of which shall be the number of shares of Common Stock outstanding immediately prior to such
subdivision, combination or reclassification. Such increase or reduction, as the case may be,
shall become effective immediately after the opening of business on the day upon which such
subdivision or combination becomes effective.

     (c) In case the Company shall, at any time or from time to time while any of the Securities
are outstanding, distribute rights, warrants or options for a period expiring within 60 days after
the Record Date of such issuance (other than any rights, warrants or options issued pursuant to the
Rights Agreement or any future rights agreement adopted by the Company), to all holders of its
shares of Common Stock entitling them to subscribe for or purchase shares of Common Stock (or
securities convertible into or exchangeable or exercisable for shares of Common Stock), at a price
per share less than the Current Market Price of the Common Stock on the declaration date for such
distribution, then the Conversion Rate shall be adjusted so that the same shall equal the rate
determined by multiplying the Conversion Rate in effect at the opening of business on the
Ex-Dividend Date for such distribution by a fraction:

     (i) the numerator of which shall be the number of shares of Common Stock outstanding
at the close of business on the Business Day immediately preceding the Ex-Dividend Date
for such distribution, plus the total number of additional shares of Common Stock so
offered for subscription or purchase; and

     (ii) the denominator of which shall be the number of shares of Common Stock
outstanding on the close of business on the Business Day immediately preceding the
Ex-Dividend Date for such distribution, plus the number of shares of Common Stock which
the aggregate offering price of the total number of shares of Common Stock so offered for
subscription or purchase would purchase at the Current Market Price of the Common Stock on
the declaration date for such distribution (determined by multiplying such total number of shares of Common Stock so offered by the exercise price of such rights, warrants or
options and dividing the product so obtained by such Current Market Price).

     Such adjustment shall become effective immediately after the opening of business on the
Ex-Dividend Date for such distribution.

     To the extent that shares of Common Stock are not delivered pursuant to such rights, warrants
or options, upon the expiration or termination of such rights, warrants or options, the Conversion
Rate shall be readjusted to the Conversion Rate which would then be in effect had the adjustments
made upon the issuance of such rights, warrants or options been made on the basis of the delivery
of only the number of shares of Common Stock actually delivered. In the event that such

39

 

rights, warrants or options are not so distributed, the Conversion Rate shall again be
adjusted to be the Conversion Rate which would then be in effect if the Ex-Dividend Date for such
distribution had not occurred. In determining whether any rights, warrants or options entitle the
holders to subscribe for or purchase shares of Common Stock at less than such Current Market Price,
and in determining the aggregate offering price of such shares of Common Stock, there shall be
taken into account any consideration received for such rights, warrants or options and the value of
such consideration if other than Cash, to be determined in good faith by the Board of Directors or
the Chief Financial Officer of the Company. In no event shall the Conversion Rate be decreased
pursuant to this Section 4.03(c), except as described in the first two sentences of this paragraph.

     (d) In case the Company shall, at any time or from time to time while any of the Securities
are outstanding, by dividend or otherwise, distribute to all holders of its shares of Common Stock
(including any such distribution made in connection with a consolidation or merger in which the
Company is the continuing corporation and the Common Stock is not changed or exchanged), shares of
its Capital Stock (other than any dividends or distributions to which Section 4.03(a) applies),
evidences of its indebtedness or other assets, including securities, but excluding (x) any rights
or warrants referred to in Section 4.03(c), (y) rights or warrants distributed pursuant to the
Rights Agreement or any future rights agreement adopted by the Company, and (z) dividends and
distributions paid exclusively in Cash (such Capital Stock, evidence of its indebtedness, other
non-Cash assets or securities being distributed hereinafter in this Section 4.03(d) called the
"distributed assets”), then, in each such case, subject to the other provisions of this Section
4.03(d), the Conversion Rate shall be increased so that the same shall be equal to the rate
determined by multiplying the Conversion Rate in effect immediately prior to the opening of
business on the Ex-Dividend Date with respect to such distribution by a fraction:

     (i) the numerator of which shall be the Current Market Price of the Common Stock; and

     (ii) the denominator of which shall be such Current Market Price of the Common Stock,
less the Fair Market Value on such date of the portion of the distributed assets so
distributed applicable to one share of Common Stock (determined on the basis of the number
of shares of Common Stock outstanding on such Ex-Dividend Date) (determined as provided in
Section 4.03(g)).

     Such increase shall become effective immediately after the opening of business on the
Ex-Dividend Date for such dividend or distribution. In the event that such dividend or
distribution is not so paid or made, the Conversion Rate shall again be adjusted to be the
Conversion Rate which would then be in effect if such dividend or distribution had not been
declared.

40

 

     If the Board of Directors or the Chief Financial Officer of the Company determines the Fair
Market Value of any distribution for purposes of this Section 4.03(d) by reference to the actual or
when issued trading market for any distributed assets comprising all or part of such distribution,
it must in doing so consider the prices in such market over the same period (the “Reference
Period”) used in computing the Current Market Price pursuant to Section 4.03(g) to the extent
possible, unless the Board of Directors or the Chief Financial Officer of the Company determines in
good faith that determining the Fair Market Value during the Reference Period would not be in the
best interest of the Holders.

     Notwithstanding the foregoing, if the distributed assets distributed by the Company to all
holders of the Common Stock consist of capital stock of, or similar equity interests in, a
Subsidiary or other business unit of the Company (a “Spin-Off”), the Conversion Rate shall be
increased so that the same shall be equal to the rate determined by multiplying the Conversion Rate
in effect immediately prior to the opening of business on the fifteenth Trading Day following the
Ex-Dividend Date for such distribution by a fraction,

     (i) the numerator of which shall be the sum of (A) the average of the Closing Sale
Prices of the Common Stock for the ten consecutive Trading Days commencing on and
including the fifth Trading Day after the Ex-Dividend for such distribution on The Nasdaq
National Market, The New York Stock Exchange, or such other principal national or regional
exchange or market or quotation system on which such securities are then listed or quoted,
plus (B) the average Closing Sale Prices of the securities distributed in respect of each
share of Common Stock for the ten consecutive Trading Days commencing on and including the
fifth Trading Day after such Ex-Dividend Date; and

     (ii) the denominator of which shall be the average of the Closing Sale Prices of the
Common Stock for the ten consecutive Trading Days commencing on and including the fifth
Trading Day after such Ex-Dividend Date,

such adjustment to become effective immediately after the opening of business on the fifteenth
Trading Day following the Ex-Dividend Date for such distribution.

     Rights or warrants distributed by the Company to all holders of Common Stock entitling the
holders thereof to subscribe for or purchase shares of the Company’s capital stock (either
initially or under certain circumstances), which rights, options or warrants, until the occurrence
of a specified event or events (“Trigger Event”): (i) are deemed to be transferred with such shares
of Common Stock; (ii) are not exercisable; and (iii) are also issued in respect of future issuances
of Common Stock, shall be deemed not to have been distributed for purposes of this Section 4.03
(and no adjustment to the Conversion Rate under this Section 4.03 will be required) until the
occurrence of the earliest Trigger Event, whereupon such rights, options and warrants shall be
deemed to have been

41

 

distributed and an appropriate adjustment (if any is required) to the Conversion Rate shall be
made under this Section 4.03(d). If any such right, option or warrant, including any such existing
rights, options or warrants distributed prior to the date of this Indenture, are subject to events,
upon the occurrence of which such rights, options or warrants become exercisable to purchase
different securities, evidences of indebtedness or other assets, then the date of the occurrence of
any and each such event shall be deemed to be the date of distribution and record date with respect
to new rights, options or warrants with such rights (and a termination or expiration of the
existing rights, options or warrants without exercise by any of the holders thereof). In addition,
in the event of any distribution (or deemed distribution) of rights, options or warrants, or any
Trigger Event or other event (of the type described in the preceding sentence) with respect thereto
that was counted for purposes of calculating a distribution amount for which an adjustment to the
Conversion Rate under this Section 4.03 was made, (1) in the case of any such rights, options or
warrants that shall all have been redeemed or repurchased without exercise by any holders thereof,
the Conversion Rate shall be readjusted upon such final redemption or repurchase to give effect to
such distribution or Trigger Event, as the case may be, as though it were a Cash distribution,
equal to the per share redemption or repurchase price received by a holder or holders of Common
Stock with respect to such rights, options or warrants (assuming such holder had retained such
rights, options or warrants), made to all holders of Common Stock as of the date of such redemption
or repurchase, and (2) in the case of such rights, options or warrants that shall have expired or
been terminated without exercise by any holders thereof, the Conversion Rate shall be readjusted as
if such rights, options and warrants had not been issued.

     For purposes of this Section 4.03(d), Section 4.03(a) and Section 4.03(c), any dividend or
distribution to which this Section 4.03(d) is applicable that also includes shares of Common Stock,
or rights, options or warrants to subscribe for or purchase shares of Common Stock (or both), shall
be deemed instead to be (1) a dividend or distribution of the evidences of indebtedness, assets or
shares of capital stock other than such shares of Common Stock or rights, options or warrants (and
any Conversion Rate adjustment required by this Section 4.03(d) with respect to such dividend or
distribution shall then be made) immediately followed by (2) a dividend or distribution of such
shares of Common Stock or such rights, options or warrants (and any further Conversion Rate
adjustment required by Section 4.03(a) and Section 4.03(c) with respect to such dividend or
distribution shall then be made), except any shares of Common Stock included in such dividend or
distribution shall not be deemed “outstanding at the close of business on the Business Day
immediately preceding such Ex-Dividend Date” within the meaning of Section 4.03(a).

     The reclassification of the Common Stock into securities including securities other than
Common Stock (other than any reclassification upon an event to which Section 4.04 applies) shall be
deemed to involve (a) a distribution of such securities other than the Common Stock to all holders
of Common Stock

42

 

(and the effective date of such reclassification shall be deemed to be the “Ex-Dividend Date”
within the meaning of this Section 4.03(d)), and (b) a subdivision or combination, as the case may
be, of the number of shares of Common Stock outstanding immediately prior to such reclassification
into the number of shares of Common Stock outstanding immediately thereafter (and the effective
date of such reclassification shall be deemed to be “the day upon which such subdivision becomes
effective” or “the day upon which such combination becomes effective,” as the case may be, and “the
day upon which such subdivision or combination becomes effective” within the meaning of Section
4.03(b)).

     In no event shall the Conversion Rate be decreased pursuant to this Section 4.03(d), except
pursuant to the last sentence of each of the second and fifth paragraphs of this Section 4.03(d).

     (e) In case the Company shall, at any time or from time to time while any of the Securities
are outstanding, by dividend or otherwise, distribute to all holders of its shares of Common Stock,
Cash (excluding (v) any dividend or distribution in connection with our liquidation, dissolution or
winding up, (w) any Cash that is distributed upon a reclassification, change, merger,
consolidation, statutory share exchange, combination, sale or conveyance to which Section 4.04 or
4.13 applies, (x) any Cash distributed as part of a distribution referred to in Section 4.03(d) and
(y) any Cash that is distributed pursuant to a tender offer, to which Section 4.03(f) applies)
then, and in each case, immediately after the close of business on such date, the Conversion Rate
shall be increased so that the same shall equal the rate determined by multiplying the Conversion
Rate in effect immediately prior to the opening of business of the Ex-Dividend Date for such
distribution by a fraction:

     (i) the numerator of which shall be equal to the Current Market Price per share of
Common Stock (as determined pursuant to Section 4.03(g) on such Record Date); and

     (ii) the denominator of which shall be equal to (a) the Current Market Price per
share of Common Stock on such date, less the amount of the distribution per share of
Common Stock.

     Such increase shall become effective immediately after the opening of business on the
Ex-Dividend Date for such dividend or distribution. In the event that such dividend or
distribution is not so paid or made, the Conversion Rate shall again be adjusted to be the
Conversion Rate which would then be in effect if such dividend or distribution had not been
declared. In no event shall the Conversion Rate be decreased pursuant to this Section 4.03(e),
except pursuant to the immediately preceding sentence.

     (f) In case the Company or any of its Subsidiaries shall, at any time or from time to time,
while any of the Securities are outstanding, distribute to all holders of the Company’s common
stock Cash or other consideration in respect of

43

 

a tender offer or exchange offer made by the Company or any Subsidiary for all or any portion
of the Common Stock (excluding any Cash that is distributed upon a reclassification, change,
merger, consolidation, statutory share exchange, combination, sale or conveyance to which Section
4.04 applies or as part of a distribution referred to in Sections 4.03(d) or 4.03(e)), where the
sum of the aggregate amount of such Cash distributed and the aggregate Fair Market Value (as
determined in good faith by the Board of Directors of the Company, whose determination shall be
conclusive and set forth in a Board Resolution), as of the Expiration Date (as defined below), of
such other consideration distributed (such sum, the “Aggregate Amount”) expressed as an amount per
share of Common Stock validly tendered or exchanged, and not withdrawn, pursuant to such tender
offer or exchange offer as of the Expiration Time (as defined below) (such tendered or exchanged
shares of Common Stock, the “Purchased Shares”) exceeds the Closing Sale Price per share of the
Common Stock on the first Trading Day immediately following the last date (such last date, the
"Expiration Date”) on which tenders or exchanges could have been made pursuant to such tender offer
or exchange offer (as the same may be amended through the Expiration Date), then, and in each case,
immediately after the close of business on such date, the Conversion Rate shall be increased so
that the same shall equal the rate determined by multiplying the Conversion Rate in effect
immediately prior to the close of business on the Trading Day immediately following the Expiration
Date by a fraction:

     (i) the numerator of which is equal to the sum of (A) the Aggregate Amount and (B)
the product of (I) the Closing Sale Price per share of the Common Stock on the first
Trading Day immediately following the Expiration Date and (II) an amount equal to (1) the
number of shares of Common Stock outstanding as of last time (the “Expiration Time”) at
which tenders or exchanges could have been made pursuant to such tender offer or exchange
offer less (2) the Purchased Shares; and

     (ii) the denominator of which shall be equal to the product of (A) the number of shares of Common Stock outstanding as of the Expiration Time (including all Purchased
Shares) and (B) the Closing Sale Price per share of the Common Stock on the first Trading
Day immediately following the Expiration Date.

     An adjustment, if any, to the Conversion Rate pursuant to this Section 4.03(f) shall become
effective immediately prior to the opening of business on the second Trading Day immediately
following the Expiration Date. In the event that the Company or a Subsidiary is obligated to
purchase shares of Common Stock pursuant to any such tender offer or exchange offer, but the
Company or such Subsidiary is permanently prevented by applicable law from effecting any such
purchases, or all such purchases are rescinded, then the Conversion Rate shall again be adjusted to
be the Conversion Rate which would then be in effect if such tender offer or exchange offer had not
been made. If the application of this Section 4.03(f) to any tender offer or exchange offer would
result in a decrease in

44

 

the Conversion Rate, no adjustment shall be made for such tender offer or exchange offer under
this Section 4.03(f), except pursuant to the immediately preceding sentence.

     (g) For purposes of this Article 4, the following terms shall have the meanings indicated:

     “Current Market Price” per share of the Company’s Common Stock on the date of determination
means the average of the Closing Sale Prices per share of the Common Stock for the ten consecutive
Trading Days ending on the earlier of the day of determination and the day immediately preceding
the Ex-Dividend Date with respect to the distribution requiring such computation. If another
issuance, distribution, subdivision or combination to which Section 4.03 applies occurs during the
period applicable for calculating “Current Market Price” pursuant to the definition in the
preceding paragraph, “Current Market Price” shall be calculated for such period in a manner
determined by the Chief Financial Officer of the Company to reflect the impact of such issuance,
distribution, subdivision or combination on the Closing Sale Price of the Common Stock during such
period.

     For purposes of this Indenture, the term “Ex-Dividend Date”, when used:

     (i) with respect to any issuance or distribution, means the first date on which the shares of Common Stock trade regular way on the relevant exchange or in the relevant
market from which the Closing Sale Price was obtained without the right to receive such
issuance or distribution;

     (ii) with respect to any subdivision or combination of shares of Common Stock, means
the first date on which the shares of Common Stock trade regular way on such exchange or
in such market after the time at which such subdivision or combination becomes effective;
and

     (iii) with respect to any tender or exchange offer, means the first date on which the shares of Common Stock trade regular way on such exchange or in such market after the
expiration of such offer.

     Notwithstanding the foregoing, whenever successive adjustments to the Conversion Rate are
called for pursuant to this Section 4.03, such adjustments shall be made to the Current Market
Price as may be necessary or appropriate to effectuate the intent of this Section 4.03 and to avoid
unjust or inequitable results as determined in good faith by the Chief Financial Officer of the
Company.

     “Fair Market Value” shall mean the amount which a willing buyer would pay a willing seller in
an arm’s length transaction (as determined in good faith by the Board of Directors or the Chief
Financial Officer of the Company, whose good faith determination shall be conclusive).

45

 

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

     (h) The Company shall be entitled at its election to make such additional increases in the
Conversion Rate, in addition to those required by 4.03(a), (b), (c), (d), (e) or (f), as shall be
necessary in order that any dividend or distribution of Common Stock, any subdivision,
reclassification or combination of shares of Common Stock or any issuance of rights or warrants
referred to above shall not be taxable to the holders of Common Stock for United States federal
income tax purposes.

     (i) To the extent permitted by applicable law and the continued quotation requirements of The
Nasdaq National Market, the Company may, from time to time, increase the Conversion Rate by any
amount for any period of time, if such period is at least 20 days or any longer period required by
law, the Chief Financial Officer of the Company determines that the increase in the Conversion Rate
is in the best interest of the Company, and the increase is irrevocable during the period.
Whenever the Conversion Rate is increased pursuant to the preceding sentence, the Company shall
mail to the Trustee and each Holder at the address of such Holder as it appears in the register of
the Securities maintained by the Registrar, at least 15 days prior to the date the increased
Conversion Rate takes effect, a notice of the increase stating the increased Conversion Rate and
the period during which it will be in effect.

     (j) All calculations under this Section 4.03 shall be made to the nearest cent or one
ten-thousandth of a share, with one-half cent and 0.00005 of a share, respectively, being rounded
upward. Notwithstanding any other provision of this Section 4.03, the Company shall not be
required to make any adjustment of the Conversion Rate unless such adjustment would require an
increase or decrease of at least 1% of such rate; provided that any lesser adjustment shall be
carried forward and shall be made at the time of and together with the next subsequent adjustment
which, together with any adjustment or adjustments so carried forward, shall amount to an increase
or decrease of at least 1% in such rate; and provided, further, that at the end of each fiscal year
of the Company, beginning with the fiscal year ending on December 31, 2006, and at the time of
conversion of any Securities, any adjustments to the Conversion Rate that have been, and at such
time remain, deferred pursuant to this Section 4.03(j) shall be given effect, and such adjustments,
if any, shall no longer be carried forward and taken into account in any subsequent adjustment to
the Conversion Rate. Any adjustments under this Section 4.03 shall be made successively whenever
an event requiring such an adjustment occurs.

46

 

     (k) In the event that at any time, as a result of an adjustment made pursuant to this Section
4.03, the Holder of any Securities thereafter surrendered for conversion shall become entitled to
receive any shares of stock of the Company other than shares of Common Stock into which the
Securities originally were convertible, the Conversion Rate of such other shares so receivable upon
conversion of any such Security shall be subject to adjustment from time to time in a manner and on
terms as nearly equivalent as practicable to the provisions with respect to Common Stock contained
in subparagraphs (a) through (i) of this Section 4.03, and the provisions of Sections 4.01, 4.02,
4.04 through 4.09 and 4.13 with respect to the Common Stock shall apply on like or similar terms
to any such other shares and the good faith determination of the Board of Directors or the Chief
Financial Officer of the Company as to any such adjustment shall be conclusive.

     (l) No adjustment shall be made pursuant to this Section 4.03 if the Holders of the Securities
may participate, without conversion, in the transaction or event that would otherwise give rise to
an adjustment pursuant to this Section 4.03 at the same time as holders of the Common Stock
participate with respect to such transaction or event and on the same terms as holders of the
Common Stock participate with respect to such transaction or event as if Holders of Securities
held, at such time, a number of shares of Common Stock equal to the Conversion Rate at such time.

     Section 4.04 . Consolidation or Merger of the Company. Except as provided in Section 4.13,
if any of the following events (any such event, a “Disposition Event”) occurs:

     (a) any reclassification or change of the outstanding Common Stock into another class of
Capital Stock (other than a change in par value, or from par value to no par value, or from no par
value to par value, or as a result of a subdivision or combination);

     (b) any merger, consolidation, binding share exchange or other business combination of the
Company with another Person as a result of which all of the holders of Common Stock shall be
entitled to receive stock, securities or other property or assets (including Cash or any
combination thereof) with respect to or in exchange for all of their Common Stock; or

     (c) any sale, conveyance, transfer, lease or other disposition of all or substantially all the
properties and assets of the Company to any other Person as a result of which all of the holders of
Common Stock shall be entitled to receive stock, securities or other property or assets (including
Cash or any combination thereof) with respect to or in exchange for all of their Common Stock;

the Company or the successor or purchasing person, as the case may be, shall execute with the
Trustee a supplemental indenture (which shall comply with the TIA as in force at the date of
execution of such supplemental indenture, if such

47

 

supplemental indenture is then required to so comply) providing that notwithstanding the provisions
of Section 4.02(b), and subject to the provisions of Section 4.01, the Conversion Rate following
the effective date of any Disposition Event shall be calculated based on the kind and amount of
stock, securities, other property, assets or Cash received (collectively, “Reference Property”)
upon such Disposition Event by a holder of Common Stock holding, immediately prior to the
transaction, a number of shares of Common Stock equal to the Conversion Rate immediately prior to
such Disposition Event.

     In the event that the holders of the Common Stock have the opportunity to elect the form of
the consideration to be received in such Disposition Event, the Company shall make adequate
provision whereby Holders shall have a reasonable opportunity to determine the form of
consideration into which all of the Securities, treated as a single class, shall be convertible
from and after the effective date of such Disposition Event. Such determination shall be based on
the weighted average of elections made by Holders of the Securities who participate in such
determination, shall be subject to any limitations to which all of the holders of Common Stock are
subject, such as pro-rata reductions applicable to any portion of the consideration payable in such
Disposition Event and shall be conducted in such a manner as to be completed by the date which is
the earliest of (x) the deadline for elections to be made by holders of Common Stock, and (y) two
Trading Days prior to the anticipated effective date of the Disposition Event. In the event the
effective date of the Disposition Event is delayed beyond the initially anticipated effective date,
Holders of the Securities shall be given the opportunity to make subsequent similar determinations
in regard to such delayed effective date. The Company shall provide notice of the opportunity to
determine the form of such consideration, as well as notice of the determination made by Holders by
issuing a press release and providing a copy of such notice to the Trustee. The Company shall not
become a party to any Disposition Event the terms of which are inconsistent with the foregoing.

     If the Conversion Rate is calculated based on Reference Property as set forth above, the
related Conversion Obligation, with respect to each $1,000 Principal Amount of Securities tendered
for conversion after the effective date of any such Disposition Event, shall be settled in units of
Reference Property in accordance with Section 4.02(b) which the Company shall deliver, as promptly
as practicable, but in no event later than on the third Trading Day immediately following the
Determination Date.

     Notwithstanding clause (c) above, if the Securities are surrendered for conversion prior to
the effective date of any such Disposition Event, and the Company shall be obligated to increase
the Conversion Rate pursuant to Section 4.13(b) and deliver additional shares Common Stock
following the effective date of such Disposition Event, in lieu of shares of Common Stock, the
Company shall instead deliver units of the kind and amount of Reference Property as a holder of the
relevant number of shares of Common Stock would have received in such Disposition Event.

48

 

     Such supplemental indenture shall provide for adjustments which shall be as nearly equivalent
as may be practicable to the adjustments provided for in this Article 4. If, in the case of any
such Disposition Event, the stock or other securities and assets receivable thereupon by a holder
of Common Stock includes shares of stock or other securities and assets of a corporation other than
the successor or purchasing corporation, as the case may be, in such Disposition Event, then such
supplemental indenture shall also be executed by such other corporation and shall contain such
additional provisions to protect the interests of the Holders of the Securities as the Board of
Directors or the Chief Financial Officer of the Company shall reasonably consider necessary by
reason of the foregoing.

     The Company shall cause notice of the execution of such supplemental indenture to be mailed to
each Holder, at the address of such Holder as it appears on the register of the Securities
maintained by the Registrar, within 20 days after execution thereof. Failure to deliver such
notice shall not affect the legality or validity of such supplemental indenture.

     The above provisions of this Section 4.04 shall similarly apply to successive Disposition
Events.

     If this Section 4.04 applies to any event or occurrence, Section 4.03 shall not apply.

     Section 4.05 . Notice of Adjustment. Whenever an adjustment in the Conversion Rate with
respect to the Securities is required:

     (a) the Company shall forthwith place on file with the Trustee and any Conversion Agent for
such Securities a certificate of the Treasurer of the Company (upon which the Trustee may
conclusively rely), stating the adjusted Conversion Rate determined as provided herein and setting
forth in reasonable detail such facts as shall be necessary to show the reason for and the manner
of computing such adjustment; and

     (b) a notice stating that the Conversion Rate has been adjusted and setting forth the adjusted
Conversion Rate shall forthwith be given by the Company or, at the Company’s request, by the
Trustee in the name and at the expense of the Company, to each Holder in the manner provided in
Section 4.02 hereof. Any notice so given shall be conclusively presumed to have been duly given,
whether or not the Holder receives such notice.

     Section 4.06 . Notice in Certain Events. (a) If:

     (i) the Company shall engage in a tender offer or declare a dividend (or any other
distribution) on its Common Stock that would require an adjustment in the Conversion Rate
pursuant to Section 4.03; or

49

 

     (ii) the Company shall authorize the granting to all of the holders of its Common
Stock of rights, warrants or options to subscribe for or purchase shares of Common Stock;
or

     (iii) there occurs any reclassification or change 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, merger, binding share exchange or combination to which the Company is a
party, or of the sale, lease, transfer conveyance or other disposition of all or
substantially all of the assets of the Company; or

     (iv) there occurs any 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 Securityholder at his
address appearing on the register for the Securities, provided for in Section 2.03 of this
Indenture, as promptly as possible but in any event at least twenty 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, warrants or options, 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, warrants or options are to be determined, or (y) the date on which such
reclassification, change, consolidation, merger, binding share exchange, combination, sale,
transfer, lease, conveyance, other disposition, 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, change, consolidation, merger, binding share exchange,
combination, sale, transfer, lease, conveyance, other disposition, 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, change, consolidation, merger, binding
share exchange, combination, sale, transfer, lease, conveyance, other disposition, dissolution,
liquidation or winding-up.

     Section 4.07 . Company to Reserve Stock; Registration; Listing. (a) The Company shall from
time to time reserve and keep available, free from preemptive rights, out of its authorized but
unissued shares of Common Stock for the purpose of effecting the conversion of the Securities, such
number of its duly authorized shares of Common Stock as shall from time to time be sufficient to
effect the conversion of all Securities then outstanding at any time (assuming that the Company
elects to deliver solely shares of Common Stock to satisfy the Net Share Amount for all
conversions). The Company covenants that all shares of Common Stock which may be issued upon
conversion of Securities will upon issue be fully paid and nonassessable and free from all liens
and charges and, except as provided in Section 4.08, taxes with respect to the issue thereof.

50

 

     (b) If any shares of Common Stock which would be issuable upon conversion of Securities
hereunder require registration with or approval of any governmental authority before such shares or
securities may be issued upon such conversion, the Company will use its best efforts to cause such
shares or securities to be duly registered or approved, as the case may be. The Company further
covenants that so long as the Common Stock shall be quoted on The Nasdaq National Market, the
Company will use its reasonable best efforts, if permitted by the rules of The Nasdaq National
Market, to have and keep approved for quoting on The Nasdaq National Market (subject to notice of
official issuance) all Common Stock issuable upon conversion of the Securities, and the Company
will use its reasonable best efforts to list the shares of Common Stock required to be delivered
upon conversion of the Securities prior to such delivery upon any other national securities
exchange upon which the outstanding Common Stock is listed at the time of such delivery.

     Section 4.08 . Taxes on Conversion. The issue of stock certificates on conversion of
Securities shall be made without charge to the converting Holder for any documentary, stamp or
similar issue or transfer taxes in respect of the issue thereof, and the Company shall pay any and
all documentary, stamp or similar issue or transfer taxes that may be payable in respect of the
issue or delivery of shares of Common Stock on conversion of Securities pursuant hereto. The
Company shall not, however, be required to pay any such tax which may be payable in respect of any
transfer involved in the issue or delivery of shares of Common Stock or the portion, if any, of the
Securities which are not so converted in a name other than that in which the Securities so
converted were registered, and no such issue or delivery shall be made unless and until the Person
requesting such issue has paid to the Company the amount of such tax or has established to the
satisfaction of the Company that such tax has been paid.

     Nothing contained herein shall preclude any income tax withholding required by law or
regulation upon conversion of the Securities, and at the Company’s request, Holders shall be
responsible for satisfying any such withholding.

     Section 4.09 . Conversion After Record Date. Except as provided in this Section 4.09, a
converting Holder of Securities shall not be entitled to receive any accrued and unpaid interest,
if any (including Additional Interest, if any), on any such Securities being converted. By
delivery to the Holder of the shares of Common Stock due upon conversion and cash in lieu of
fractional shares, if any, or other consideration issuable or payable upon conversion in accordance
with this Article 4, any accrued and unpaid interest, if any (including Additional Interest, if
any), on such Securities will be deemed to have been paid in full rather than cancelled,
extinguished or forfeited. If any Securities are surrendered for conversion subsequent to the
Regular Record Date preceding an Interest Payment Date but prior to such Interest Payment Date, the
Holder of such Securities at the close of business on such Regular Record Date shall receive the
interest payable on such Security on such Interest Payment Date notwithstanding the conversion

51

 

thereof. Securities surrendered for conversion during the period from the close of business
on any Regular Record Date preceding any Interest Payment Date to the opening of business on such
Interest Payment Date shall be accompanied by payment from converting Holders, for the account of
the Company, in Cash of an amount equal to the interest payable on such Interest Payment Date on
the Securities being surrendered for conversion; provided, however, that no such interest payment
need be made to the Company (i) if the Company has specified a Redemption Date that is after a
Regular Record Date but on or prior to the next Interest Payment Date, (ii) if the Company has
specified a Fundamental Change Repurchase Date following a Fundamental Change that is after a
Regular Record Date but on or prior to the next Interest Payment Date, or (iii) to the extent of
any Defaulted Interest, if any Defaulted Interest exists at the time of conversion with respect to
such Security.

     Except as provided in this Section 4.09, no adjustments in respect of payments of interest
(including Additional Interest, if any) on Securities surrendered for conversion or any dividends
or distributions or interest on the Common Stock issued upon conversion shall be made upon the
conversion of any Securities.

     Section 4.10 . Company Determination Final. Any determination that the Company or the Board
of Directors must make pursuant to this Article 4 shall be conclusive if made in good faith and in
accordance with the provisions of this Article, absent manifest error, and set forth in a Board
Resolution or an Officers’ Certificate of the Company’s Chief Financial Officer, as the case may
be.

     Section 4.11 . Responsibility of Trustee for Conversion Provisions. The Trustee has no duty
to determine when an adjustment under this Article 4 should be made, how it should be made or what
it should be. Unless and until a Trust Officer of the Trustee receives a certificate delivered
pursuant to Section 4.05 setting forth an adjustment of the Conversion Rate, the Trustee may assume
without inquiry that no such adjustment has been made and that the last Conversion Rate of which
the Trustee has knowledge remains in effect. The Trustee makes no representation as to the
validity or value of any securities or assets issued upon conversion of Securities. The Trustee
shall not be responsible for any failure of the Company to comply with this Article 4. Each
Conversion Agent other than the Company shall have the same protection under this Section 4.11 as
the Trustee.

     The rights, privileges, protections, immunities and benefits given to the Trustee under this
Indenture including, without limitation, its rights to be indemnified, are extended to, and shall
be enforceable by, the Trustee in each of its capacities hereunder, and each Paying Agent or
Conversion Agent acting hereunder.

     Section 4.12 . Unconditional Right of Holders to Convert. Notwithstanding any other
provision in this Indenture, the Holder of any Security

52

 

shall have the right, which is absolute and unconditional, to convert its Security in
accordance with this Article 4 and to bring an action for the enforcement of any such right to
convert, and such rights shall not be impaired or affected without the consent of such Holder.

     Section 4.13 . Adjustment to the Conversion Rate Upon Certain Fundamental Changes. (a) If a
Make-Whole Fundamental Change occurs prior to March 15, 2011, then the Conversion Rate then in
effect will (subject to the Company’s rights described under paragraph (c) of this Section 4.13)
increase, as described in paragraph (b) of this Section 4.13, with respect to any Securities
surrendered for conversion at any time from, and including, the effective date of such Make-Whole
Fundamental Change until, and including, the close of business on the Business Day immediately
preceding the Fundamental Change Repurchase Date or the fundamental change repurchase date that
would have been applicable to such Make-Whole Fundamental Change but for the existence of the 110%
trading price exception in clause (i) of the definition of Change in Control, as applicable The
Company shall mail notice to Holders, at their addresses appearing in the Security register,
publish on its website and publicly announce, through a reputable national newswire service, that
the Make-Whole Fundamental Change has occurred within five Business Days after such Make-Whole
Fundamental Change has occurred. If applicable, the Company shall also state, in such notice and
publication, whether the Company has made the election referred to in paragraph (c) of this Section
4.13.

     (b) The increase in the Conversion Rate referred to in paragraph (a) of this Section 4.13 will
be determined by reference to the table below, based on the date on which the Make-Whole
Fundamental Change becomes effective (the “Effective Date”) and the applicable price (the “Stock
Price”) with respect to such Make-Whole Fundamental Change. In the case of a Make-Whole
Fundamental Change described in clause (c) of the definition of Change in Control, if the
consideration (excluding Cash payments for fractional shares or pursuant to statutory appraisal
rights) for the Common Stock in the Make-Whole Fundamental Change consists solely of Cash, then the
“Stock Price” will be the Cash amount paid per share of Common Stock in the Make-Whole Fundamental
Change. Otherwise, the “Stock Price” will be the average of the Closing Sale Prices per share of
Common Stock for the five consecutive Trading Days immediately preceding the Effective Date of the
relevant Make-Whole Fundamental Change. The Chief Financial Officer of the Company will make
appropriate adjustments, in his or her good faith determination, 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 those five consecutive
Trading Days. The Stock Prices set forth in the left column of the table below shall be adjusted
as of any date on which the Conversion Rate is adjusted pursuant to Section 4.03. The adjusted
Stock Prices shall equal the Stock Prices applicable immediately prior to such adjustment,
multiplied by a fraction, the numerator of which is the Conversion Rate immediately prior to the
adjustment giving rise to the Stock Price adjustment

53

 

and the denominator of which is the Conversion Rate as so adjusted. The number of additional
shares of Common Stock will be adjusted in the same manner and for the same events as the
Conversion Rate pursuant to Section 4.03. The following table sets forth for a given Stock Price
and Effective Date, the number of additional shares of Common Stock issuable per $1,000 Principal
Amount of Securities that will be added to the Conversion Rate applicable to the Securities
surrendered for conversion during the period described in paragraph (a) of this Section 4.13:

     In the event that the applicable Stock Price or Effective Date is not set forth in the
table above, then, if:

     (i) the applicable Stock Price is between two Stock Prices on the table or the
applicable Effective Date is between two Effective Dates on the table, the adjustment to
the Conversion Rate will be determined by straight-line interpolation between the
adjustments set forth for the higher and lower Stock Price or the earlier and later
Effective Dates, as applicable, based on a 365-day year;

     (ii) the applicable Stock Price is in excess of $60.00 per share (subject to
adjustment), no adjustment to the Conversion Rate will be made; or

     (iii) the applicable Stock Price is less than $15.47 per share (subject to
adjustment), no adjustment to the Conversion Rate will be made.

54

 

     Notwithstanding the foregoing, in no event will the total number of shares of Common Stock
issuable upon conversion of a Security exceed 64.6412 per $1,000 Principal Amount of Securities,
subject to adjustments in the same manner as the Conversion Rate, as set forth in Section 4.03.

     (c) Notwithstanding the foregoing, if the Make-Whole Fundamental Change is a Public Acquiror
Fundamental Change, then the Company may elect to change the conversion right in lieu of increasing
the Conversion Rate pursuant to paragraphs (a) and (b) of this Section 4.13. If the Company makes
this election, then the Company shall adjust the Conversion Rate and the Company’s related
Conversion Obligation such that, from and after the Effective Date of the Public Acquiror
Fundamental Change, the right to convert a Security will be changed into a right to convert such
Security into shares of Public Acquirer Common Stock in the same manner as is described in Section
4.02(b). The Conversion Rate adjusted pursuant to this paragraph (c) shall be a Conversion Rate
equal to the Conversion Rate in effect immediately before the Effective Date for such Public
Acquiror Fundamental Change multiplied by a fraction:

     (i) the numerator of which is the Fair Market Value, as of the effective time of the
Public Acquiror Fundamental Change, of the Cash, securities and other property paid or
payable per share of Common Stock; and

     (ii) the denominator of which is the average of the last reported sale prices per
share of the Public Acquirer Common Stock for the five consecutive Trading Days commencing
on, and including, the Trading Day immediately after the Effective Date of the Public
Acquiror Fundamental Change.

     If the Company elects to change the conversion right pursuant to this paragraph (c), the
change in the conversion right will apply to all Holders from and after the Effective Date of the
Public Acquiror Fundamental Change, and not just those Holders, if any, that convert their
Securities during the period described in paragraph (a) of this Section 4.13. If the Public
Acquiror Fundamental Change is also an event that requires the Company to make another adjustment
to the Conversion Rate pursuant to Section 4.03, then the Company shall also give effect to that
adjustment. However, if the Company makes the election set forth in this paragraph (c), then the
Company shall not change the Conversion Right in the manner set forth in Section 4.04.

     (d) The Company shall state, in the notice and public announcement described in paragraph (a)
of this Section 4.13 whether the Company has elected to change the conversion right in accordance
with paragraph (c) of this Section 4.13 in lieu of increasing the Conversion Rate in accordance
with paragraphs (a) and (b) of this Section 4.13. With respect to each Public Acquiror Fundamental
Change, the Company is permitted to make only one election, and the Company is prohibited from
changing that election once the Company has first mailed any

55

 

such notice or made any such public announcement or publication. However, if the Company
elects to change the conversion right as described in paragraph (c) of this Section 4.13 in
connection with a Public Acquiror Fundamental Change that is ultimately not consummated, then the
Company shall not be obligated to give effect to that particular election.

     Section 4.14 . Stockholder Rights Plan. There shall be no adjustment to the Conversion Rate
upon the issuance of the rights (the “Rights”) provided for in the Rights Agreement, or in any
future rights plan adopted by the Company, prior to the Rights separating from the Common Stock.
To the extent that the Rights Agreement, or any future rights plan adopted by the Company, is in
effect upon conversion of the Securities, Holders shall receive, in addition to any Common Stock
issuable upon conversion, the Rights under the Rights Agreement or any such future rights agreement
adopted by the Company, unless the Rights have separated from the Common Stock at the time of
conversion and the Rights Agreement or any such future rights agreement does not provide for the
issuance upon conversion of the Securities of a number of Rights equal to the number of Rights that
a holder of a number of shares of Common Stock equal to the applicable Conversion Rate would have
received upon such separation, in which case the Conversion Rate will be adjusted at the time of
separation as if the Company had distributed to all holders of the Common Stock, distributed assets
as described in Section 4.03(d) above, subject to readjustment in the event of the expiration,
termination or redemption of such Rights.

ARTICLE 5

Covenants

     Section 5.01 . Payment of Securities. The Company shall promptly make all payments in
respect of the Securities on the dates and in the manner provided in the Securities and this
Indenture. The Principal Amount or an installment of interest (including Additional Interest, if
any) shall be considered paid on the date it is due if the Paying Agent (other than the Company)

thereof, sufficient to pay the installment. The Company shall, (in immediately available funds) to
the fullest extent permitted by law, pay interest on overdue Principal Amount and overdue
installments of interest at the rate borne by the Securities per annum.

     Payment of the Principal Amount of and any interest (including Additional Interest, if any) on
the Securities shall be made at the office or agency of the Company maintained for that purpose in
The Borough of Manhattan, The City of New York or at the Corporate Trust Office of the Trustee in
such coin or currency of the United States of America as at the time of payment is legal tender for
payment of public and private debts. The Company will make payments in respect of the Global
Securities by wire transfer of immediately available funds to the accounts specified by the Holders
of the Global Securities. For a Global

56

 

Security that has been subsequently issued in certificated form, the Company will mail a check
to the Holder’s registered address.

     Section 5.02 . SEC and Other Reports. The Company shall furnish to the Trustee promptly upon
filing thereof, copies of all registration statements, current reports and annual, quarterly or
other regular reports that the Company files with the SEC, including, without limitation, all

and Section 906 of the Sarbanes-Oxley Act of 2002, as amended, and the rules and regulations
related thereto. To the extent permitted by the TIA and other applicable law, such filings shall
be deemed to have been furnished to the Trustee upon their filing on the SEC’s EDGAR system.

     The Company shall furnish to the Trustee within one hundred five (105) days after the close of
each of the Company’s fiscal years, annual audited consolidated financial statements for the
Company and its Subsidiaries, including a consolidated balance sheet as of the end of such period,
related statement of consolidated income, statement of consolidated shareowners’ equity, and
statement of cash flows, and statement of cash flows, accompanied by an unqualified audit report of
independent auditors. To the extent permitted by the TIA and other applicable law, such financial
statements shall be deemed to have been furnished to the Trustee upon their filing on the SEC’s
EDGAR system as part of a Form 10-K filing by the Company.

     The Company shall furnish to the Trustee within fifty-five (55) days after the close of the
first three quarterly periods of each of the Company’s fiscal years, unaudited consolidated
financial statements for the Company and its Subsidiaries, including a consolidated balance sheet
as of the end of such period, related statement of consolidated income and statement of cash flows,
for the period from the beginning of such fiscal year to the end of such quarter. To the extent
permitted by the TIA and other applicable law, such financial statements shall be deemed to have
been furnished to the Trustee upon their filing on the SEC’s EDGAR system as part of a Form 10-Q
filing by the Company.

     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 5.03 . Compliance Certificates. The Company shall deliver to the Trustee, within 120
days after the end of each fiscal year of the Company (beginning with the fiscal year ending
December 31, 2006), an Officers’ Certificate as to the signer’s knowledge of the Company’s
compliance with all conditions and covenants on its part contained in this Indenture and stating
whether or not the signer knows of any default or Event of Default. If such signer

57

 

knows of such a default or Event of Default, the Officers’ Certificate shall describe the
default or Event of Default and the efforts to remedy the same. For the purposes of this Section
5.03, compliance shall be determined without regard to any grace period or requirement of notice
provided pursuant to the terms of this Indenture.

     Section 5.04 . Further Instruments and Acts. Upon request of the Trustee or as necessary,
the Company will execute and deliver such further instruments and do such further acts as may be
reasonably necessary or proper to carry out more effectively the purposes of this Indenture.

     Section 5.05 . Maintenance of Corporate Existence. Subject to Article 6, the Company will do
or cause to be done all things necessary to preserve and keep in full force and effect its
corporate existence.

     Section 5.06 . Rule 144A Information Requirement. Within the period prior to the expiration
of the holding period applicable to sales thereof under Rule 144(k) under the Securities Act (or
any successor provision), the Company covenants and agrees that it shall, during any period in
which it is not subject to Section 13 or 15(d) under the Exchange Act, upon the request of any
Holder or beneficial holder of the Securities make available to such Holder or beneficial holder of
Securities or any Common Stock issued upon conversion thereof which continue to be Transfer
Restricted Securities in connection with any sale thereof and any prospective purchaser of
Securities or such 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 such 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. Upon the
request of any Holder or any beneficial holder of the Securities or such Common Stock, the Company
will deliver to such Holder a written statement as to whether it has complied with such
requirements.

     Section 5.07 . Stay, Extension and Usury Laws. The Company covenants (to the extent that it
may lawfully do so) that it shall not at any time insist upon, plead, or in any manner whatsoever
claim or take the benefit or advantage of, any stay, extension or usury law or other law which
would prohibit or forgive the Company from paying all or any portion of the Principal Amount of, or
interest (including Additional Interest, if any) on, the Securities as contemplated herein,
wherever enacted, now or at any time hereafter in force, or which may affect the covenants or the
performance of this Indenture, and the Company (to the extent it may lawfully do so) hereby
expressly waives all benefit or advantage of any such law and covenants that it will not, by resort
to any such law, hinder, delay or impede the execution of any power herein granted to the Trustee,
but will suffer

58

 

and permit the execution of every such power as though no such law had been enacted.

     Section 5.08 . Payment of Additional Interest. If Additional Interest is payable by the
Company pursuant to the Registration Rights Agreement, the Company shall deliver to the Trustee a
certificate to that effect stating (i) the amount of such Additional Interest per $1,000 principal
amount of the Securities that is payable, (ii) the facts and calculations supporting the
determination of such amount and (iii) 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 such 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 a
certificate setting forth the particulars of such payment.

     Section 5.09 . Limitation on Other Indebtedness. The Company covenants and agrees not to
create, incur, assume or suffer to exist any indebtedness for borrowed money pursuant to one or
more agreements, any of which contain an event of default that is triggered by the occurrence of an
event of default under any agreement or agreements pursuant to which the Company has outstanding
indebtedness for borrowed money in excess of $15,000,000 in the aggregate; provided that for
purposes of this covenant, (i) the term “borrowed money” shall not include Credit Facilities, (ii)
notwithstanding the foregoing, in no event shall this covenant restrict the Company’s ability to
create, incur, assume or suffer to exist any indebtedness for borrowed money pursuant to an
agreement that contains an event of default that is triggered by an event of default in the payment
at final maturity of indebtedness for borrowed money by the Company, or acceleration of the
Company’s indebtedness for borrowed money so that it becomes due and payable before the date on
which it would otherwise have become due and payable and (iii) notwithstanding the foregoing, the
Company may incur indebtedness for borrowed money of any other Person that is existing at the time
of a merger or consolidation of such other Person with or into the Company or any of its
Subsidiaries so long as (A) such indebtedness is not incurred in connection with, or in
contemplation of, such merger or consolidation and (B) such other Person is not an Affiliate of the
Company prior to the entry into the operative agreement or agreements relating to such merger or
consolidation.

ARTICLE 6

Consolidation, Merger, Conveyance, Transfer or Lease

consolidate with or merge with or into any other Person (unless the Company is the surviving
Person) or convey, sell, transfer, lease or otherwise dispose all or substantially all of its
properties and assets to any Person

59

 

(other than a direct or indirect wholly-owned Subsidiary) whether in a single transaction or
series of related transactions, unless:

     (a) either

     (i) in the case of a consolidation or merger, the Company is the surviving entity;

     (ii) the conveyance, sale, transfer, lease or other disposition of all or
substantially all of the Company’s properties and assets is to a direct or indirect
wholly-owned Subsidiary; or

     (iii) the successor or transferee is a corporation, limited liability company,
partnership or trust or other business entity organized and existing under the laws of the
United States, any state thereof, or the District of Columbia and expressly assumes, by an
indenture supplemental hereto, executed and delivered to the Trustee, all of the
obligations of the Company under the Securities and the Indenture; and

     (b) immediately after giving effect to such transaction or series of transactions, no Default
or Event of Default shall exist; and

     (c) the Company shall have delivered to the Trustee an Officers’ Certificate and, if requested
by the Trustee, an Opinion of Counsel, each stating that such consolidation, merger, conveyance,
transfer, sale, lease or other disposition and, if a supplemental indenture is required in
connection with such transaction, such supplemental indenture, comply with this Article 6 and that
all conditions precedent herein provided for relating to such transaction have been satisfied.

     Section 6.02 . Successor Substituted. Upon any consolidation of the Company with, or merger
of the Company into, any other Person or any conveyance, sale, transfer, lease or other disposition
of all or substantially all of the properties and assets of the Company in accordance with Section
6.01, the successor Person formed by such consolidation or into which the Company is merged or to
which such conveyance, sale, transfer or lease is made shall succeed to, and be substituted for,
and may exercise every right and power of, the Company under this Indenture with the same effect as
if such successor Person had been named as the Company herein, and thereafter, except in the case
of a lease, the predecessor Person shall be relieved of all obligations and covenants under this
Indenture and the Securities.

ARTICLE 7

Default and Remedies

     Section 7.01 . Events of Default. An “Event of Default” shall occur if:

     (a) the Company fails to pay the Principal Amount of any Security, when due, whether on the
Final Maturity Date, Redemption Date, Repurchase Date, Fundamental Change Repurchase Date or
otherwise;

     (b) the Company fails to pay an installment of interest on any Security in full when due if
the failure continues for a period of 30 days after the date when due;

     (c) the Company fails to timely satisfy its Conversion Obligation following the exercise by
the Holder of the right to convert such Security;

     (d) the Company fails to timely provide a Repurchase Notice or a Fundamental Change Repurchase

required under Sections 4.13(a) and (d) regarding the adjustment of the Conversion Rate upon the
occurrence of a Make-Whole Fundamental Change;

     (e) the Company fails to comply with any other term, covenant or agreement contained in the
Securities or this Indenture (other than those referred to in clauses (a) through (d) above) if
such failure continues for 60 days after receipt by the Company of a Notice of Default (defined
below);

     (f) the Company or any of its Subsidiaries defaults in the payment at final maturity of
indebtedness for money borrowed in the aggregate principal amount then outstanding of $15,000,000
or more, or acceleration of the Company’s or any of its Subsidiaries’ indebtedness for money
borrowed in such aggregate principal amount or more so that it becomes due and payable before the
date on which it would otherwise have become due and payable, if such default is not cured or
waived, or such acceleration is not rescinded, within 30 days after receipt by the Company of a
Notice of Default;

     (g) the Company or any of its Significant Subsidiaries, pursuant to or under or within the
meaning of the Bankruptcy Code:

     (i) commences a voluntary case or proceeding;

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

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

61

 

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

     (v) files a petition in bankruptcy or answer or consent seeking reorganization or
relief; or

     (vi) consents to the filing of such petition or the appointment of or taking
possession by a Custodian;

     (h) a court of competent jurisdiction enters an order or decree under the Bankruptcy Code
that:

     (i) is for relief against the Company or any Significant Subsidiary (or any group of
Subsidiaries that, together, constitute a Significant Subsidiary), in an involuntary case
or proceeding;

     (ii) appoints a Custodian of the Company or any Significant Subsidiary (or any group
of Subsidiaries that, together, constitute a Significant Subsidiary), or for any
substantial part of its property; or

     (iii) orders the winding up or liquidation of the Company or any Significant
Subsidiary (or any group of Subsidiaries that, together, constitute a Significant
Subsidiary),

     (iv) and in each case the order or decree remains unstayed and in effect for 90
consecutive days.

     For purposes of this Section 7.01, a “Notice of Default” means a written notice provided to
the Company by the Trustee, or to the Trustee and the Company by Holders of at least 25% in
aggregate Principal Amount of the Securities then outstanding, of the applicable default. Such
notice must specify the default, demand that it be remedied and state that the notice is a Notice
of Default. When any default under this Section 7.01 is cured, it ceases.

     The Trustee shall not be charged with knowledge of any Event of Default unless written notice
thereof shall have been given to a Trust Officer at the Corporate Trust Office of the Trustee by
the Company, a Paying Agent, any Holder or any agent of any Holder.

     Notwithstanding anything else contained herein, if an Event of Default has occurred and is
continuing, then the Company shall not (A) (except in the case of an Event of Default resulting
from a default by the Company in the payment of the Redemption Price with respect to such
Securities) redeem any of the Securities pursuant to Article 3 hereof, (B) (except in the case of
an Event of Default resulting from a default by the Company in the payment of the Repurchase Price
with respect to such Securities) repurchase any of the Securities pursuant to Section 3.08 hereof,
or (C) (except in the case of an Event of Default resulting from a default by the Company in the
payment of the Fundamental

62

 

Change Repurchase Price with respect to such Securities) repurchase any of the Securities
pursuant to Section 3.09 hereof.

     Section 7.02 . Acceleration. If an Event of Default occurs, the Company shall promptly
notify the Trustee thereof. If an Event of Default (excluding an Event of Default specified in
clause (g) or (h) of Section 7.01 in respect of the Company) occurs and is continuing, the Trustee
may, by notice to the Company, or the Holders of at least 25% in aggregate Principal Amount of the
Securities then outstanding may, by notice to the Company and the Trustee, declare all unpaid
Principal Amount to the date of acceleration on the Securities then outstanding (if not then due
and payable) to be due and payable upon any such declaration, and the same plus any interest, if
any (including Additional Interest, if any), on the Securities accrued but unpaid through the date
of such declaration shall become and be immediately due and payable. If an Event of Default
specified in clause (g) or (h) of Section 7.01 occurs in respect of the Company, the entire unpaid
Principal Amount of the Securities then outstanding and such interest (including Additional
Interest, if any), shall ipso facto become and be immediately due and payable without any
declaration or other act on the part of the Trustee or any Holder. The Holders of a majority in
aggregate Principal Amount of the Securities then outstanding by notice to the Trustee may rescind
an acceleration and its consequences if (a) the rescission would not conflict with any order or
decree of a court of competent jurisdiction; (b) all existing Events of Default, other than the
non-payment of the accelerated Principal Amount or interest, have been cured or waived; and (c)
certain amounts due to the Trustee and any predecessor Trustee under Section 8.07 are paid. No
such rescission shall affect any subsequent default or impair any right consequent thereto.

     Section 7.03 . Other Remedies. If an Event of Default occurs and is continuing, the Trustee
may, but shall not be obligated to, pursue any available remedy by proceeding at law or in equity
to collect the payment of the Principal Amount of or 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
Securityholder 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 to the extent permitted by
law.

     Section 7.04 . Waiver of Defaults and Events of Default. Subject to Sections 7.07 and 10.02,
the Holders of a majority in aggregate Principal Amount of the Securities then outstanding by
notice to the Trustee may waive any past default or Event of Default and its consequence, except a
default or Event of Default in the payment of the Principal Amount of, or interest on, any
Security, or the payment of the Redemption Price, the Repurchase Price or Fundamental

63

 

Change Repurchase Price, a Default or Event of Default arising from the Company’s failure to
convert any Security in accordance with the terms of Article 4 or any default or Event of Default
in respect of any provision of this Indenture or the Securities which, under Section 10.02, cannot
be modified or amended without the consent of the Holder of each Security affected. When a default
or Event of Default is waived, it is cured and ceases.

     Section 7.05 . Control by Majority. The Holders of a majority in aggregate Principal Amount
of the Securities then outstanding may direct the time, method and place of conducting any
proceeding for any remedy available to the Trustee or exercising any trust or power conferred on
it. However, the Trustee may refuse to follow any direction that conflicts with law or this
Indenture, that the Trustee determines may be prejudicial to the rights of another Holder or the
Trustee, or that may involve the Trustee in personal liability unless the Trustee is offered
indemnity satisfactory to it. In addition, the Trustee may take any other action deemed proper by
the Trustee which is not inconsistent with such direction.

     Section 7.06 . Limitations on Suits. A Holder may not pursue any remedy with respect to this
Indenture or the Securities (except actions for payment of overdue Principal Amount of, or interest
on, or for the conversion of the Securities pursuant to Article 4) unless:

     (a) the Holder gives to the Trustee written notice of a continuing Event of Default;

     (b) the Holders of at least 25% in aggregate Principal Amount of the then outstanding
Securities make a written request to the Trustee to pursue the remedy;

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

     (d) the Trustee does not comply with the request within 60 days after receipt of the
notice, request and the offer of indemnity, and does not receive, during those 60 days,
from Holders of a majority in aggregate Principal Amount of the Securities then
outstanding, a direction that is inconsistent with the request.

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

     Section 7.07 . Rights of Holders to Receive Payment and to Convert. Notwithstanding any
other provision of this Indenture, the right of any Holder of a Security to receive payment of the
Principal Amount of and interest on the Security, on or after the respective dates expressed in the
Security and this Indenture on which such payments are due and payable, to convert such Security

64

 

in accordance with Article 4 and to bring suit for the enforcement of any such payment on or
after such respective dates or the right to convert, is absolute and unconditional and shall not be
impaired or affected without the consent of the Holder.

     Section 7.08 . Collection Suit by Trustee. If an Event of Default in the payment of the
Principal Amount or interest specified in clause (a) or (b) of Section 7.01 occurs and is
continuing, the Trustee may recover judgment in its own name and as trustee of an express trust
against the Company or another obligor on the Securities for the whole amount of the Principal
Amount and accrued interest remaining unpaid, if any, together with, to the extent that payment of
such interest is lawful, interest on overdue Principal Amount and on overdue installments of
interest, in each case at the rate per annum borne by the Securities and such further amount as
shall be sufficient to cover the costs and expenses of collection, including the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents and counsel.

     Section 7.09 . 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 (or any other obligor on the Securities), its creditors or its property and
shall be entitled and empowered to collect and receive any money or other property payable or
deliverable on any such claims and to distribute the same, and any Custodian in any such judicial
proceeding is hereby authorized by each Holder to make such payments to the Trustee and, in the
event that the Trustee shall consent to the making of such payments directly to the Holders, to pay
to the Trustee any amount due to it for the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under
Section 8.07, and to the extent that such payment of the reasonable compensation, expenses,
disbursements and advances in any such proceedings shall be denied for any reason, payment of the
same shall be secured by a lien on, and shall be paid out of, any and all distributions, dividends,
money, securities and other property which the Holders may be entitled to receive in such
proceedings, whether in liquidation or under any plan of reorganization or arrangement or
otherwise. Nothing herein contained shall be deemed to authorize the Trustee to authorize or
consent to, or, on behalf of any Holder, to authorize, accept or adopt any plan of reorganization,
arrangement, adjustment or composition affecting the Securities or the rights of any Holder
thereof, or to authorize the Trustee to vote in respect of the claim of any Holder in any such
proceeding.

     Section 7.10 . Priorities. If the Trustee collects any money pursuant to this Article 7, it
shall pay out the money in the following order:

     First, to the Trustee for amounts due under Section 8.07;

65

 

     Second, to Holders for amounts due and unpaid on the Securities for the Principal Amount and
interest (including Additional Interest, if any), ratably, without preference or priority of any
kind, according to the amounts due and payable on the Securities for the Principal Amount and
interest (including Additional Interest, if any), respectively; and

     Third, the balance, if any, to the Company.

     The Trustee may fix a record date and payment date for any payment to Holders pursuant to this
Section 7.10.

     Section 7.11 . Undertaking for Costs. In any suit for the enforcement of any right or remedy
under this Indenture or in any suit against the Trustee for any action taken or omitted by it as
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 7.11 does not apply to a suit made by the Trustee, a suit by a Holder
pursuant to Section 7.07, or a suit by Holders of more than 10% in aggregate Principal Amount of
the Securities then outstanding.

ARTICLE 8

Trustee

     Section 8.01 . Duties of Trustee. (a) If an Event of Default has occurred and is continuing,
the Trustee shall exercise such of the rights and powers vested in it by this Indenture and use the

circumstances in the conduct of his or her own affairs.

     (i) the Trustee need perform only those duties as are specifically set forth in this
Indenture and no others; 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 or opinions furnished to the Trustee and conforming to the requirements of
this Indenture. The Trustee, however, shall examine any certificates and opinions which
by any provision hereof are specifically required to be delivered to the Trustee to
determine whether or not they conform to the requirements of this Indenture.

66

 

     (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 subsection (b) of this Section 8.01;

     (ii) the Trustee shall not be liable for any error of judgment made in good faith by
a Trust Officer, unless it is proved that the Trustee was negligent in ascertaining the
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 7.05.

     (d) No provision of this Indenture shall require the Trustee to expend or risk its own funds
or otherwise incur any financial liability in the performance of any of its duties hereunder or in
the exercise of any of its rights or powers unless the Trustee shall have received adequate
indemnity in its opinion against potential costs and liabilities incurred by it relating thereto.

     (e) Every provision of this Indenture that in any way relates to the Trustee is subject to
subsections (a), (b), (c) and (d) of this Section 8.01.

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

     Section 8.02 . Rights of Trustee. Subject to Section 8.01:

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

     (b) Before the Trustee acts or refrains from acting, it may require an Officers’ Certificate
or an Opinion of Counsel, which shall conform to Section 12.04(b). The Trustee shall not be liable

Opinion.

     (c) The Trustee may act through its agents and shall not be responsible for the misconduct or

any such action taken, omitted or

67

 

suffered by it hereunder in good faith and in accordance with the advice or opinion of such
counsel.

     (f) The Trustee shall be under no obligation to exercise any of the rights or powers vested in
it by this Indenture at the request or direction of any of the Holders pursuant to this Indenture,
unless such Holders shall have offered to the Trustee security or indemnity satisfactory to the
Trustee against the costs, expenses and liabilities which might be incurred by it in compliance
with such request or direction.

     (g) The Trustee shall not be bound to make any investigation into the facts or matters stated
in any resolution, certificate, statement, instrument, opinion, report, notice, request, direction,
consent, order, bond, debenture, note, other evidence of indebtedness or other paper or document,
but the Trustee, in its discretion, may make such further inquiry or investigation into such facts
or matters as it may see fit, and, if the Trustee shall determine to make such further inquiry or
investigation, it shall be entitled to examine the books, records and premises of the Company,
personally or by agent or attorney at the sole cost of the Company and shall incur no liability or
additional liability of any kind by reason of such inquiry or investigation.

     (h) Except with respect to Section 5.01, the Trustee shall have no duty to inquire as to the
performance of the Company with respect to the covenants contained in Article 5. In addition, the
Trustee shall not be deemed to have knowledge of an Event of Default except (i) any Default or
Event of Default occurring pursuant to Section 5.01, Section 7.01(a) or Section 7.01(b) or (ii) any
Default or Event of Default of which the Trustee shall have received written notification or

     (i) 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 to each agent, custodian and
other Person employed to act hereunder.

     (j) Delivery of reports, information and documents to the Trustee under Section 5.02 is for
informational purposes only and the Trustee’s receipt of the foregoing shall not constitute
constructive notice of any information contained therein or determinable from information contained
therein, including the Company’s compliance with any of its covenants hereunder (as to which the
Trustee is entitled to rely exclusively on Officer’s Certificates).

     (k) In no event shall the Trustee be responsible or liable for special, indirect or
consequential loss or damage of any kind whatsoever (including, but not limited to, loss of profit)
irrespective of whether the Trustee has been advised of the likelihood of such loss or damage and
regardless of the form of action.

     Section 8.03 . Individual Rights of Trustee. The Trustee in its individual or any other
capacity may become the owner or pledgee of Securities and may

68

 

otherwise deal with the Company or an Affiliate of the Company with the same rights it would
have if it were not Trustee. Any Agent may do the same with like rights. However, the Trustee is
subject to Sections 8.10 and 8.11.

     Section 8.04 . Trustee’s Disclaimer. The Trustee makes no representation as to the validity
or adequacy of this Indenture or the Securities, it shall not be accountable for the Company’s use
of the proceeds from the Securities, and it shall not be responsible for any statement of the
Company in the Securities other than its certificate of authentication.

     Section 8.05 . Notice of Default or Events of Default. If a default or an Event of Default
occurs and is continuing and the Trustee has received notice thereof, the Trustee shall mail to
each Securityholder notice of the default or Event of Default within 30 days after it occurs or, if
later, within 15 Business Days after the Trustee has received notice thereof. However, the Trustee
may withhold the notice if and so long as such default or Event of Default has been cured or
waived, or a committee of its Trust Officers in good faith determines that withholding notice is in
the interests of Securityholders, except in the case of a default or an Event of Default in payment
of the Principal Amount of or interest on any Security.

     Section 8.06 . Reports by Trustee to Holders. If such report is required by TIA Section 313,
within 60 days after each May 15, beginning with the May 15, 2007, the Trustee shall mail to each
Securityholder a brief report dated as of such May 15 that complies with TIA Section 313(a). The
Trustee also shall comply with TIA Section 313(b)(2) and (c).

     A copy of each report at the time of its mailing to Securityholders shall be mailed to the
Company and filed with the SEC and each stock exchange, if any, on which the Securities are listed.
The Company shall notify the Trustee whenever the Securities become listed on any stock exchange
or listed or admitted to trading on any quotation system and any changes in the stock exchanges or
quotation systems on which the Securities are listed or admitted to trading and of any delisting
thereof.

     Section 8.07 . Compensation and Indemnity. The Company shall pay to the Trustee from time to
time such compensation (as agreed to from time to time by the Company and the Trustee in writing)
for its services (which compensation shall not be limited by any provision of law in regard to the
compensation of a trustee of an express trust). The Company shall reimburse the Trustee upon
request for all reasonable disbursements, expenses and advances incurred or made by it. Such
expenses may include the reasonable compensation, disbursements and expenses of the Trustee’s
agents and counsel.

     The Company shall indemnify the Trustee or any predecessor Trustee (which for purposes of this
Section 8.07 shall include its officers, directors, employees and agents) for, and hold it harmless
against, any and all loss, liability,

69

 

claim, damage or expense including taxes (other than taxes based upon, measured by or
determined by the income of the Trustee), including reasonable legal fees and expenses, incurred by
it in connection with the acceptance or administration of its duties under this Indenture or any
action or failure to act as authorized or within the discretion or rights or powers conferred upon
the Trustee hereunder including the reasonable costs and expenses of the Trustee and its counsel in
defending itself against any claim or liability in connection with the exercise or performance of
any of its powers or duties hereunder. The Trustee shall notify the Company promptly of any claim
asserted against the Trustee for which it may seek indemnity. The Company need not pay for any
settlement without their written consent, which consent shall not be unreasonably withheld.

     The Company need not reimburse the Trustee for any expense or indemnify it against any loss or
liability incurred by it resulting from its negligence or bad faith.

     To secure the Company’s payment obligations in this Section 8.07, the Trustee shall have a
senior claim to which the Securities are hereby made subordinate on all money or property held or
collected by the Trustee, except such money or property held in trust to pay the Principal Amount
of and interest on the Securities. The obligations of the Company under this Section 8.07 shall
survive the satisfaction and discharge of this Indenture or the resignation or removal of the
Trustee.

     When the Trustee incurs expenses or renders services after an Event of Default specified in
clause (i) or (j) of Section 7.01 occurs, the expenses and the compensation for the services are
intended to constitute expenses of administration under the Bankruptcy Code. The provisions of
this Section shall survive the termination of this Indenture.

     Section 8.08 . Replacement of Trustee. The Trustee may resign by so notifying the Company.
The Holders of a majority in aggregate Principal Amount of the Securities then outstanding may
remove the Trustee by so notifying the Trustee and may, with the Company’s written consent, appoint
a successor Trustee. The Company may remove the Trustee if:

     (a) the Trustee fails to comply with Section 8.10;

     (b) the Trustee is adjudged a bankrupt or an insolvent;

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

     (d) the Trustee becomes incapable of acting.

     If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any
reason, the Company shall promptly appoint a successor Trustee. The resignation or removal of a
Trustee shall not be effective until a successor

70

 

Trustee shall have delivered the written acceptance of its appointment as described below.

     If a successor Trustee does not take office within 45 days after the retiring Trustee resigns
or is removed, the retiring Trustee, the Company or the Holders of 10% in Principal Amount of the
Securities then outstanding may petition any court of competent jurisdiction for the appointment of
a successor Trustee at the expense of the Company.

     If the Trustee fails to comply with Section 8.10, any Holder may petition any court of
competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee.

     A successor Trustee shall deliver a written acceptance of its appointment to the retiring
Trustee and to the Company. Immediately after that, the retiring Trustee shall (upon payment of
its charges hereunder) transfer all property held by it as Trustee to the successor Trustee and be
released from its obligations (exclusive of any liabilities that the retiring Trustee may have
incurred while acting as Trustee) hereunder, 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. A successor Trustee shall mail notice of its succession to each
Holder.

     A retiring Trustee shall not be liable for the acts or omissions of any successor Trustee
after its succession.

     Notwithstanding replacement of the Trustee pursuant to this Section 8.08, the Company’s
obligations under Section 8.07 shall continue for the benefit of the retiring Trustee.

     Section 8.09 . Successor Trustee by Merger, Etc. If the Trustee consolidates with, merges or
converts into, or transfers all or substantially all of its corporate trust assets (including the
administration of this Indenture) to, another corporation, the resulting, surviving or transferee
corporation, without any further act, shall be the successor Trustee, provided such transferee
corporation shall qualify and be eligible under Section 8.10. Such successor Trustee shall
promptly mail notice of its succession to the Company and each Holder.

     Section 8.10 . Eligibility; Disqualification. The Trustee shall always satisfy the
requirements of paragraphs (1), (2) and (5) of TIA Section 310(a). The Trustee (or its parent
holding company) shall have a combined capital and surplus of at least $50,000,000. If at any time
the Trustee shall cease to satisfy any such requirements, it shall resign immediately in the manner
and with the effect specified in this Article 8. The Trustee shall be subject to the provisions of
TIA Section 310(b). Nothing herein shall prevent the Trustee from filing with the SEC the
application referred to in the penultimate paragraph of TIA Section 310(b).

71

 

     Section 8.11 . Preferential Collection of Claims Against Company. The Trustee shall comply
with TIA Section 311(a), excluding any creditor relationship listed in TIA Section 311(b). A
Trustee who has resigned or been removed shall be subject to TIA Section 311(a) to the extent
indicated therein.

ARTICLE 9

Satisfaction and Discharge of Indenture

     Section 9.01 . Satisfaction and Discharge of Indenture. This Indenture shall cease to be of
further effect if:

     (a) either:

     (i) all outstanding Securities (other than Securities replaced pursuant to Section
2.07) have been delivered to the Trustee for cancellation or

     (ii) all outstanding Securities have been called for Redemption or have become due
and payable on the Final Maturity Date or upon repurchase pursuant to Section 3.08 or
3.09,

and in any such case the Company irrevocably deposits, prior to the applicable date on which such
payment is due and payable, with the Trustee or the Paying Agent (if the Paying Agent is not the
Company or any of its Affiliates) Cash, and, if applicable as herein provided and in accordance
herewith, such other consideration, sufficient to pay all amounts due and owing on all outstanding
Securities (other than Securities replaced pursuant to Section 2.07) on the Final Maturity Date or
a Repurchase Date, Redemption Date or Fundamental Change Repurchase Date, as the case may be;

     (b) the Company pays to the Trustee all other sums payable hereunder by the Company;

     (c) no Default or Event of Default with respect to the Securities shall exist on the date of
such deposit;

     (d) such deposit shall not result in a breach or violation of, or constitute a Default or
Event of Default under, this Indenture or any other agreement or instrument to which the Company is
a party or by which it is bound; and

     (e) the Company has delivered to the Trustee an Officer’s Certificate and an Opinion of
Counsel (which may rely upon such Officer’s Certificate as to the absence of Defaults and Events of
Default and as to any factual matters), each stating that all conditions precedent provided for
herein relating to the satisfaction and discharge of this Indenture have been complied with.

72

 

     Notwithstanding the satisfaction and discharge of this Indenture, the obligations of the
Company to the Trustee under Section 8.07 shall survive and, if money shall have been deposited
with the Trustee pursuant to clause (a) of this Section, the provisions of Sections 2.03, 2.04,
2.05, 2.06, 2.07, 2.12, 3.08 and 3.09, Article 4, the last paragraph of Section 5.01 and this
Article 9, shall survive and the Company shall be required to make all payments and deliveries
required by such Sections or Articles, as the case may be, irrespective of any prior satisfaction
and discharge until the Securities have been paid in full.

     Section 9.02 . Application of Trust Money. Subject to the provisions of Section 9.03, the
Trustee or a Paying Agent shall hold in trust, for the benefit of the Holders, all money deposited
with it pursuant to Section 9.01 and shall apply the deposited money in accordance with this
Indenture and the Securities to the payment of the Principal Amount of and interest on the
Securities.

     Section 9.03 . Repayment to Company. The Trustee and each Paying Agent shall promptly pay to
the Company upon request any excess money (a) deposited with them pursuant to Section 9.01 and (b)
held by them at any time.

     The Trustee and each Paying Agent shall pay to the Company upon request any money held by them
for the payment of the Principal Amount or interest that remains unclaimed for two years after a
right to such money has matured (which maturity shall occur, for the avoidance of doubt, on the
Final Maturity Date, the Redemption Date (with respect to any Securities redeemed pursuant to
Section 3.01), the Repurchase Date (with respect to any Securities purchased pursuant to Section
3.08) or the Fundamental Change Repurchase Date (with respect to any Securities repurchased
pursuant to Section 3.09); provided, however, that the Trustee or such Paying Agent, before being
required to make any such payment, may at the expense of the Company cause to be mailed to each
Holder entitled to such money or publish in a newspaper of general circulation in the City of New
York notice that such money remains unclaimed and that after a date specified therein, which shall
be at least 30 days from the date of such mailing or publication, any unclaimed balance of such
money then remaining will be repaid to the Company. After payment to the Company, Holders entitled
to money must look to the Company for payment as general creditors unless an applicable abandoned
property law designates another person.

     Section 9.04 . Reinstatement. If the Trustee or any Paying Agent is unable to apply any
money in accordance with Section 9.02 by reason of any legal proceeding or by reason of any order
or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting
such application, then the Company’s obligations under this Indenture and the Securities shall be
revived and reinstated as though no deposit had occurred pursuant to Section 9.01 until such time
as the Trustee or such Paying Agent is permitted to apply all such money in accordance with Section
9.02; provided, however, that if the Company has made any payment of the Principal Amount of or
interest on any Securities because of the reinstatement of its obligations, the Company shall be
subrogated

73

 

to the rights of the Holders of such Securities to receive any such payment from the money
held by the Trustee or such Paying Agent.

ARTICLE 10

Amendments, Supplements and Waivers

     Section 10.01 . Without Consent of Holders. The Company and the Trustee may amend or
supplement this Indenture or the Securities without notice to or consent of any Securityholder:

     (a) to evidence the assumption of the Company’s obligations under this Indenture and the
Securities by a successor upon consolidation or merger or the sale, transfer, lease, conveyance or
other disposition of all or substantially all of the Company’s property or assets in accordance
with this Indenture;

     (b) to make adjustments in accordance with this Indenture to the right to convert the
Securities upon reclassifications or changes in the Common Stock pursuant to Section 4.03 and
consolidations, mergers and binding share exchanges and upon the sale, transfer, lease, conveyance
or other disposition of all or substantially all of the Company’s property or assets pursuant to
Section 4.04;

     (c) make any changes or modifications to this Indenture necessary in connection with the
registration of the public offer and sale of the Securities under the Securities Act pursuant to

     (d) to secure the obligations of the Company in respect of the Securities;

     (e) to add to the covenants of the Company described in this Indenture for the benefit of
Securityholders or to surrender any right or power conferred upon the Company; and

     (f) to make provision with respect to adjustments to the Conversion Rate as required by this
Indenture or to increase the Conversion Rate in accordance with this Indenture.

In addition, the Company and the Trustee may enter into a supplement to this Indenture to cure any
ambiguity, defect, omission or inconsistency in this Indenture in a manner that does not adversely
affect the rights of any Holder.

     Section 10.02 . With Consent of Holders. The Company and the Trustee may amend or supplement
this Indenture or the Securities with the written consent of the Holders of at least a majority in
aggregate Principal Amount of the Securities then outstanding. The Holders of at least a majority
in aggregate Principal Amount of the Securities then outstanding may waive compliance in a
particular instance by the Company with any provision of this Indenture or the Securities without
notice to any Securityholder. However, notwithstanding the

74

 

foregoing but subject to Section 10.04, without the written consent of each Securityholder
affected, an amendment, supplement or waiver, including a waiver pursuant to Section 7.04, may not:

     (a) change the Final Maturity Date of the Principal Amount of, or the payment date of any
installment of interest (including Additional Interest, if any) on, any Security;

     (b) reduce the Principal Amount of, or any interest (including Additional Interest, if any)
on, any Security;

     (c) change the place or currency of payment of Principal Amount of, or interest on (including
Additional Interest, if any), any Security;

     (d) impair the right of any Holder to institute suit for the enforcement of any payment on, or
with respect to, any Security;

     (e) modify, in a manner adverse to the Holders of Securities, the right of the Holders to
require the Company to repurchase the Securities as provided in Section 3.08 and Section 3.09;

     (f) modify, in a manner adverse to the Holders of the Securities, the right of Holders to
convert their Securities in accordance of this Indenture;

     (g) reduce the percentage in the aggregate Principal Amount of the outstanding Securities
whose Holders must consent to a modification or amendment of this Indenture or the Securities;

     (h) reduce the percentage in the aggregate Principal Amount of the outstanding Securities
whose Holders must consent to a waiver of compliance with any provision of this Indenture or the
Securities or a waiver of any Default or Event of Default under this Indenture;

     (i) modify the ranking of the Securities in a manner adverse to the Holders of the Securities;
and

     (j) modify the provisions of this Indenture with respect to modification and waiver (including
waiver of a default or Event of Default), except to increase the percentage required for
modification or waiver or to provide for the consent of each affected Holder.

     It shall not be necessary for the consent of the Holders under this Section 10.02 to approve
the particular form of any proposed amendment, supplement or waiver, but it shall be sufficient if
such consent approves the substance thereof.

     After an amendment, supplement or waiver under this Section 10.02 becomes effective, the
Company shall mail to the Holders affected thereby a notice briefly describing the amendment,
supplement or waiver. Any failure of

75

 

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

     To the extent that the Company or any of the Subsidiaries hold any Securities, such Securities
shall be disregarded for purposes of voting in connection with any notice, waiver, consent or
direction requiring the vote or concurrence of Securityholders.

     Section 10.03. Compliance with Trust Indenture Act. Every amendment to or supplement of this
Indenture or the Securities shall comply with the TIA as in effect at the date of such amendment or
supplement.

     Section 10.04. Revocation and Effect of Consents. Until an amendment, supplement or waiver
becomes effective, a consent to it by a Holder is a continuing consent by the Holder and every
subsequent Holder of a Security or portion of a Security that evidences the same debt as the
consenting Holder’s Security, even if notation of the consent is not made on any Security.
However, any such Holder or subsequent Holder may revoke the consent as to its Security or portion
of a Security if the Trustee receives the notice of revocation before the date the amendment,
supplement or waiver becomes effective.

     After an amendment, supplement or waiver becomes effective, it shall bind every
Securityholder, unless it makes a change described in any of clauses (a) through (j) of Section
10.02. In that case the amendment, supplement or waiver shall bind each Holder of a Security who
has consented to it and every subsequent Holder of a Security or portion of a Security that
evidences the same debt as the consenting Holder’s Security.

     Section 10.05. Notation on or Exchange of Securities. If an amendment, supplement or waiver
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 about 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.

     Section 10.06. Trustee to Sign Amendments, Etc. The Trustee shall sign any amendment or
supplemental indenture authorized pursuant to this Article 10 if the amendment or supplemental
indenture does not adversely affect the rights, duties, liabilities or immunities of the Trustee.
If it does, the Trustee may, in its sole discretion, but need not, sign it. In signing or refusing
to sign such amendment or supplemental indenture, the Trustee shall be provided with and, subject
to Section 8.01, shall be fully protected in relying upon, an Opinion of Counsel stating that such
amendment or supplemental indenture is authorized or permitted by this Indenture. The Company may
not sign an amendment or supplemental indenture until the Board of Directors approves it.

76

 

     Section 10.07. Effect of Supplemental Indentures. Upon the execution of any supplemental
indenture under this Article, this Indenture shall be modified in accordance therewith, and such
supplemental indenture shall form a part of this Indenture for all purposes; and every Holder of
Securities theretofore or thereafter authenticated and delivered hereunder shall be bound thereby.

     Failure to mail a notice or communication to a Securityholder or any defect in it shall not

Securityholder is mailed in the manner provided above, it is duly given, whether or not the
addressee receives it.

     Section 12.03. Communications by Holders with Other Holders. Securityholders may communicate
pursuant to TIA Section 312(b) with other Securityholders with respect to their rights under this

application by the Company to the Trustee to take any action under this Indenture, the Company

conditions precedent (including any covenants, compliance with which constitutes a
condition precedent) have been complied with.

condition or covenant provided for in this Indenture shall include:

78

 

     (i) a statement that the person making such certificate or opinion has read such

purposes of determining the identity of Holders entitled to vote or consent to any action by vote
or consent authorized or permitted under this Indenture, which record date shall not be more than
thirty (30) days prior to the date of the commencement of solicitation of such action.
Notwithstanding the provisions of Section 10.04, if a record date is fixed, those persons who were
Holders of Securities at the close of business on such record date (or their duly designated
proxies), and only those persons, shall be entitled to take such action by vote or consent or to
revoke any vote or consent previously given, whether or not such persons continue to be Holders
after such record date.

     Section 12.06. Rules by Trustee, Paying Agent, Registrar and Conversion Agent. The Trustee

directors, officers, employees or stockholders, as such, shall have any liability for any
obligations of the Company under the Securities or this Indenture or for any claim based on, in
respect of, or by reason of, such obligations or their creation. Each Holder by accepting a
Security waives and releases all such liability. Such waiver and release are part of the
consideration for the issuance of the Securities.

     Section 12.08. Legal Holidays. 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 shall accrue for the
intervening period. If a Regular Record Date is a Legal Holiday, the Regular Record Date shall not
be affected.

79

Company. Any such indenture, loan or debt agreement may not be used to interpret this Indenture.

Securities shall bind its successor. All agreements of the Trustee in this Indenture shall bind

Indenture. Each signed counterpart shall be deemed an original, but all of them together represent
the same agreement.

     Section 12.13. Separability. In case any provisions in this Indenture or in the Securities
shall be invalid, illegal or unenforceable, the validity, legality and enforceability of the
remaining provisions shall not in any way be affected or impaired thereby.

     Section 12.14. Table of Contents, Headings, Etc. 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 to be considered a part hereof, and shall in no way modify
or restrict any of the terms or provisions hereof.

     Section 12.15. No Recourse Against Others. No recourse under or upon any obligation,
covenant or agreement contained in this Indenture, or in any Security, or because of any
indebtedness evidenced thereby, shall be had against any incorporator, as such, or against any
past, present or future stockholder, employee, officer or director, as such, of the Company or of
any successor, either directly or through the Company or any successor, under any rule of law,
statute or constitutional provision or by the enforcement of any assessment or by any legal or
equitable proceeding or otherwise, all such liability being expressly waived and released by the
acceptance of the Securities by the Holders and as part of the consideration for the issue of the
Securities.

     Section 12.16. Calculations in Respect of Securities. The Company or its agents will be
responsible for making all calculations called for under the Securities including, but not limited
to, determination of the Current Market Price and Closing Sale Price of the Common Stock, the
number of shares of Common Stock issuable upon conversion and the amounts of interest on the
Securities. Any calculations made in good faith and without manifest error will be final and
binding on Holders of the Securities. The Company or its agents will be required to deliver to the
Trustee a schedule of its calculations and the Trustee will be entitled to conclusively rely upon
the accuracy of such calculations without

80

 

independent verification. The Trustee has no duty to determine when such calculations should
be made, how they should be made or what the calculations should be and shall not suffer any
liability as a result thereof.

     Section 12.17. Waiver of Jury Trial. EACH OF THE COMPANY AND THE TRUSTEE HEREBY IRREVOCABLY
WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN
ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS INDENTURE, THE SECURITIES OR THE
TRANSACTIONS CONTEMPLATED HEREBY.

     Section 12.18. Force Majeure. In no event shall the Trustee be responsible or liable for any
failure or delay in the performance of its obligations hereunder arising out of or caused by,
directly or indirectly, forces beyond its control, including, without limitation, strikes, work
stoppages, accidents, acts of war or terrorism, civil or military disturbances, nuclear or natural
catastrophes or acts of God, and interruptions, loss or malfunctions of utilities, communications
or computer (software and hardware) services; it being understood that the Trustee shall use
reasonable efforts which are consistent with accepted practices in the banking industry to resume
performance as soon as practicable under the circumstances.

[FORM OF REVERSE SIDE OF SECURITY]

INFORMATICA CORPORATION

3% CONVERTIBLE SENIOR NOTES DUE 2026

1. INTEREST

     The Company promises to pay interest on the Principal Amount of this Security at the rate of
3% per annum. The Company shall pay interest semiannually in arrears on March 15 and September 15
of each year (each, an “Interest Payment Date”), commencing on September 15, 2006. Interest on the
Securities shall accrue from the most recent date to which interest has been paid or provided for
or, if no interest has been paid, from March 13, 2006, to, but excluding, the next Interest Payment
Date or March 15, 2026, as the case may be. Interest will be computed on the basis of a 360-day
year of twelve 30-day months.

     Securities surrendered for conversion during the period from the close of business on any
March 1 or September 1 preceding any Interest Payment Date (a “Regular Record Date”) to the opening
of business on such Interest Payment Date shall be accompanied by payment from converting Holders,
for the account of the Company, in Cash of an amount equal to the interest payable (including
Additional Interest, if any) on such Interest Payment Date on the Securities being surrendered for
conversion; provided, however, that no such interest (including Additional Interest, if any)
payment need be made to the Company (i) if the Company has specified a Redemption Date that is
after a Regular Record Date but on or prior to the next Interest Payment Date, (ii) if the Company
has specified a Fundamental Change Repurchase Date following a Fundamental Change that is after a
Regular Record Date but on or prior to the next Interest Payment Date, or (iii) to the extent of
any Defaulted Interest, if any Defaulted Interest exists at the time of conversion with respect to
such Security.

2. REGISTRATION RIGHTS AGREEMENT

     The Holder of this Security is entitled to the benefits of a Registration Rights Agreement,
dated as of March 13, 2006, among the Company and the Initial Purchaser (the “Registration Rights
Agreement”).

3. METHOD OF PAYMENT

     Except as provided herein, the Company shall pay interest (including Additional Interest, if
any) on this Security (except Defaulted Interest) to the person who is the Holder of this Security
at the close of business on the Regular Record Date, next preceding the related Interest Payment
Date. The Holder must surrender this Security to a Paying Agent to collect payment of the
Principal Amount. The Company will pay the Principal Amount and interest (including Additional
Interest, if any) in money of the United States that at the time of payment is legal tender for
payment of public and private debts. Payment of the

A-7

 

Principal Amount of and any interest (including Additional Interest, if any) on the Securities
shall be made at the office or agency of the Company maintained for that purpose in The Borough of
Manhattan, The City of New York or at the Corporate Trust Office of the Trustee in such coin or
currency of the United States of America as at the time of payment is legal tender for payment of
public and private debts. The Company will make payments in respect of the Global Securities by
wire transfer of immediately available funds to the accounts specified by the Holders of the Global
Securities. For a Global Security that has been subsequently issued in certificated form, the
Company will mail a check to the Holder’s registered address.

4. PAYING AGENT, REGISTRAR AND CONVERSION AGENT

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

5. INDENTURE, LIMITATIONS

     This Security is one of a duly authorized issue of Securities of the Company designated as its
3% Convertible Senior Notes due 2026 (the “Securities”), issued under an Indenture dated as of
March 13, 2006 (together with any supplemental indentures thereto, the “Indenture”), between the
Company and the Trustee. The terms of this Security include those stated in the Indenture and
those required by or made part of the Indenture by reference to the Trust Indenture Act of 1939, as
amended, as in effect on the date of the Indenture. This Security is subject to all such terms,
and the Holder of this Security is referred to the Indenture and said Act for a statement of them.
The Securities are unsecured senior obligations of the Company initially limited to $230,000,000
aggregate Principal Amount.

6. OPTIONAL REDEMPTION

     The Securities are subject to redemption, at any time after March 15, 2011, as a whole or from
time to time in part, at the election of the Company. The “Redemption Price” is 100% of the
Principal Amount of the Securities to be redeemed, together with accrued and unpaid interest, if
any (including Additional Interest, if any), thereon up to but excluding the Redemption Date.
However, if the Redemption Date falls after a Regular Record Date and on or prior to the
corresponding Interest Payment Date, the Company will pay the full amount of accrued and unpaid
interest, if any, due on such Interest Payment Date to the Holder of record at the close of
business on the corresponding Record Date, and not to the Holder submitting such Securities for
redemption. The Company will make at least 10 semi-annual interest payments (including the interest
payments

A-8

 

on September 15, 2006 and March 15, 2011) on the Securities in the full amount required by the
indenture before the Company can redeem the Securities at its option.

     No sinking fund is provided for the Securities.

7. NOTICE OF REDEMPTION

     Notice of redemption will be mailed by first-class mail at least 30 days but not more than 60
days before the Redemption Date to each Holder of Securities to be redeemed at its registered
address. Securities in denominations larger than $1,000 may be redeemed in part, but only in whole
integral multiples of $1,000. On and after the Redemption Date, subject to the deposit with the
Paying Agent of funds sufficient to pay the Redemption Price, interest, if any (including
Additional Interest, if any), shall cease to accrue on the Securities or portions of them called
for redemption.

8. PURCHASE OF SECURITIES AT OPTION OF HOLDER OR UPON A FUNDAMENTAL CHANGE

     Subject to the terms and conditions of the Indenture, the Company shall become obligated to
repurchase, at the option of the Holder, all or any portion of the Securities held by such Holder
on each of March 15, 2011, March 15, 2016 and March 15, 2021 (each, a “Repurchase Date”) at a price
equal to 100% of the Principal Amount of those Securities to be purchased, plus any accrued and
unpaid interest, if any (including Additional Interest, if any), to, but excluding, such Repurchase
Date (the “Repurchase Price”); provided, however, that any such accrued and unpaid interest
(including Additional Interest, if any) will be paid not to the Holder submitting the Security for
repurchase on the relevant Repurchase date but instead to the Holder of record at the close of
business on the corresponding Regular Record Date. On each Repurchase Date, the Company will
purchase all Securities for which the Holder has delivered and not withdrawn a written purchase
notice. To exercise such right, a Holder shall deliver to the Paying Agent a Repurchase Notice
containing the information set forth in the Indenture, at any time from 9:00 a.m., New York City
time, on the date that is 20 Business Days immediately preceding such Repurchase Date until 5:00
p.m., New York City time, on the Business Day immediately preceding such Repurchase Date, and shall
deliver the Securities to the Paying Agent as set forth in the Indenture. The Repurchase Price for
Securities to be so repurchased must be paid in Cash.

     In the event any Fundamental Change shall occur, each Holder of Securities shall have the
right, at such Holder’s option and subject to the terms and conditions of the Indenture, to require
the Company to repurchase all of such Holder’s Securities (or portions thereof that are integral
multiples of $1,000 in Principal Amount), on a date selected by the Company (the “Fundamental
Change Repurchase Date”), which Fundamental Change Repurchase Date shall

A-9

 

be no later than thirty five (35) calendar days, and no earlier than twenty (20)
calendar days, after the date the Fundamental Change Notice is mailed in accordance with the
Indenture, and no earlier than the date such Fundamental Change occurs, at a price, payable in Cash
equal to 100% of the Principal Amount of the Securities (or portions thereof) to be so repurchased
(the “Fundamental Change Repurchase Price”), plus accrued and unpaid interest, if any, to, but
excluding, the Fundamental Change Repurchase Date. To exercise such right, a Holder shall deliver
to the Paying Agent a Fundamental Change Repurchase Notice containing the information set forth in
the Indenture, at any time prior to 5:00 p.m., New York City time, on the Business Day immediately
preceding the Fundamental Change Repurchase Date, and shall deliver the Securities to the Paying
Agent as set forth in the Indenture. The Fundamental Change Repurchase Price must be paid in Cash.

     Holders have the right to withdraw any Repurchase Notice or Fundamental Change Repurchase
Notice by delivering to the Paying Agent a written notice of withdrawal in accordance with the
provisions of the Indenture.

     If Cash sufficient to pay the Repurchase Price or Fundamental Change Repurchase Price, as the
case may be, of all Securities or portions thereof to be repurchased with respect to a Repurchase
Date or Fundamental Change Repurchase Date, as the case may be, has been deposited with the Paying
Agent, at 1:00 p.m., New York City time, on the Repurchase Date or Fundamental Change Repurchase
Date, as the case may be, then, on and after the Repurchase Date or Fundamental Change Repurchase
Date, as applicable, such Securities will cease to be outstanding and interest, if any (including
Additional Interest, if any), on such Securities will cease to accrue and the Holder thereof shall
have no other rights as such other than the right to receive the Repurchase Price or Fundamental
Change Repurchase Price upon surrender of such Security.

9. CONVERSION

     Subject to and in compliance with the provisions of the Indenture, a Holder is entitled, at
such Holder’s option, to convert the Holder’s Security (or any portion of the Principal Amount
thereof that is $1,000 or an integral multiple of $1,000 Principal Amount), at the Conversion Rate
in effect on the date of conversion in accordance with Article 4 of the Indenture.

     A Security in respect of which a Holder has delivered a Repurchase Notice or Fundamental
Change Repurchase Notice, as the case may be, exercising the right of such Holder to require the
Company to repurchase such Security may be converted only if such Repurchase Notice or Fundamental
Change Repurchase Notice is withdrawn in accordance with the terms of the Indenture.

     The initial Conversion Rate is 50.0000 shares per $1,000 Principal Amount of Securities,
subject to adjustment in certain events as described in the Indenture.

A-10

 

     To surrender a Security for conversion, a Holder must, in the case of Global Securities,
comply with the Applicable Procedures of the Depositary in effect at that time, and in the case of
Certificated Securities, (1) surrender the Security to the Conversion Agent, (2) complete and
manually sign the conversion notice below (or complete and manually sign a facsimile of such
notice) and deliver such notice to the Conversion Agent, and (3) furnish appropriate endorsements
and transfer documents.

     No fractional share of Common Stock shall be issued upon conversion of any Security. Instead,
the Company shall pay a Cash adjustment as provided in the Indenture.

     No payment or adjustment will be made for accrued and unpaid interest, if any (including
Additional Interest, if any), or dividends on the shares of Common Stock, except as provided in the
Indenture.

     The Conversion Rate is subject to adjustment as provided in Sections 4.03 and 4.13 of the
Indenture. As further provided in Section 4.04 of the Indenture and subject to Section 4.13 of the
Indenture, if the Company (i) reclassifies or changes the shares of Common Stock into another class
of Capital Stock (other than a subdivision or combination of its outstanding Common Stock, or a
change in par value, or from par value to no par value, or from no par value to par value), (ii) is
a party to a consolidation, merger or binding share exchange or other business combination of the
Company with another Person and as a result of which all the holders of the outstanding Common
Stock shall be entitled to receive stock, securities or other property or assets (including Cash or
a combination thereof) with respect to or in exchange for all of their Common Stock or (iii) sells,
conveys, transfers, leases or otherwise disposes all or substantially all of its properties and
assets to any Person as a result of which all of the holders of Common Stock shall be entitled to
receive stock, securities or other property or assets (including Cash or any combination thereof)
with respect to or in exchange for all of their Common Stock, the right to convert a Security into
shares of Common Stock shall be changed as provided in said Section 4.04. If a Public Acquiror
Fundamental Change occurs, the right to convert a Security into shares of Common Stock may be
changed as provided in Section 4.13(c) of the Indenture at the election of the Company.

10. DENOMINATIONS, TRANSFER, EXCHANGE

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

A-11

 

11. PERSONS DEEMED OWNERS

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

12. UNCLAIMED MONEY

     The Trustee and each Paying Agent shall pay to the Company upon request any money held by them
for the payment of the Principal Amount or interest that remains unclaimed for two years after a
right to such money has matured (which maturity shall occur, for the avoidance of doubt, on the
Final Maturity Date, the Redemption Date (with respect to any Securities redeemed pursuant to
Section 3.01 of the Indenture), the Repurchase Date (with respect to any Securities purchased
pursuant to Section 3.08 of the Indenture) or the Fundamental Change Repurchase Date (with respect
to any Securities repurchased pursuant to Section 3.09 of the Indenture); provided, however, that
the Trustee or such Paying Agent, before being required to make any such payment, may at the

Default; (vi) default by the Company or any of its Subsidiaries in the payment at final maturity of
indebtedness for money borrowed in the aggregate principal amount then outstanding of $15,000,000

     2. Shelf Registration.

     (a) The Company shall prepare and file, or cause to be prepared and filed, with the SEC
a Registration Statement (the “Initial Shelf Registration Statement”) for an
offering to be made on a delayed or continuous basis pursuant to Rule 415 registering the
resale from time to time by Holders thereof of all of the Registrable Securities (or, if
registration of Registrable Securities not held by Notice Holders is not permitted by the
rules and regulations of the SEC, then registering the resale from time to time by Notice
Holders of their Registrable Securities). The Initial Shelf Registration Statement shall be
filed with the SEC by the date that is ninety (90) days after the Issue Date in the case of
an Initial Shelf Registration Statement that is not an Automatic Shelf Registration
Statement, or by the date that is one hundred twenty (120) days after the Issue Date, in the
case of an Initial Shelf Registration Statement that is an Automatic Shelf Registration
Statement (the “Filing Deadline Date”). The Initial Shelf Registration Statement
shall provide for the registration of such Registrable Securities for resale by such Holders
in accordance with any reasonable method of distribution elected by the Holders. In no
event shall the Initial Shelf Registration Statement be filed with the SEC prior to
completion of the offering of the Notes contemplated by the Purchase Agreement. The Company
shall use its commercially reasonable efforts to (i) in the case of an Initial Shelf
Registration Statement that is not an Automatic Shelf Registration Statement, cause the
Initial Shelf Registration Statement to become effective under the Securities Act as
promptly as practicable but in any event by the date (the “Effectiveness Deadline
Date”) that is one hundred eighty (180) days after the Issue Date and (ii) keep the
Initial Shelf Registration Statement (and any Subsequent Shelf Registration Statement)
effective under the Securities Act until the expiration of the Effectiveness Period. At the
time the Initial Shelf Registration Statement becomes effective under the Securities Act,
each Holder that became a Notice Holder on or before the fifth Business Day prior to the
date of such effectiveness shall be named as a selling securityholder in the Initial Shelf
Registration Statement and the related Prospectus in a manner that, based on the information
known to the Company at such time of effectiveness (including, without limitation, the
information contained in such Notice Holder’s Notice and Questionnaire),

-6-

 

will permit such Holder to deliver such Prospectus to purchasers of Registrable
Securities in accordance with applicable law.

     (b) If, for any reason, at any time during the Effectiveness Period any Shelf
Registration Statement ceases to be effective under the Securities Act, or ceases to be
usable for the purposes contemplated hereunder, the Company shall use its commercially
reasonable efforts to promptly cause such Shelf Registration Statement to become effective
under the Securities Act (including obtaining the prompt withdrawal of any order suspending
the effectiveness of such Shelf Registration Statement), and in any event shall, within
fifteen (15) days of such cessation of effectiveness, (i) amend such Shelf Registration
Statement in a manner reasonably expected to obtain the withdrawal of any order suspending
the effectiveness of such Shelf Registration Statement or (ii) file an additional
Registration Statement (a “Subsequent Shelf Registration Statement”) for an offering
to be made on a delayed or continuous basis pursuant to Rule 415 registering the resale from
time to time by Holders thereof of all securities that are Registrable Securities as of the
time of such filing (or, if registration of Registrable Securities not held by Notice
Holders is not permitted by the rules and regulations of the SEC, then registering the
resale from time to time by Notice Holders of their securities that are Registrable
Securities as of the time of such filing). If a Subsequent Shelf Registration Statement is
filed, the Company shall use its commercially reasonable efforts to (A) cause such
Subsequent Shelf Registration Statement to become effective under the Securities Act as
promptly as practicable after such filing, but in no event later than the Subsequent Shelf
Registration Statement Effectiveness Deadline Date and (B) keep such Subsequent Shelf
Registration Statement (or another Subsequent Shelf Registration Statement) continuously
effective until the end of the Effectiveness Period. Each such Subsequent Shelf
Registration Statement, if any, shall provide for the registration of such Registrable
Securities for resale by such Holders in accordance with any reasonable method of
distribution elected by the Holders.

     (c) The Company shall supplement and amend any Shelf Registration Statement if required
by the rules, regulations or instructions applicable to the registration form used by the
Company for such Shelf Registration Statement, if required by the Securities Act or as
reasonably requested by the Initial Purchaser or by the Trustee on behalf of the Holders of
the Registrable Securities covered by such Shelf Registration Statement.

     (d)

     (i) Each Holder of Registrable Securities agrees that, if such Holder wishes to
sell Registrable Securities pursuant to a Shelf Registration Statement and related
Prospectus, it will do so only in accordance with this Section 2(d) and Section
3(j). Each Holder of Registrable Securities wishing to sell Registrable Securities
pursuant to a Shelf Registration Statement and related Prospectus agrees to deliver
a completed and executed Notice and Questionnaire to the Company prior to any
attempted or actual distribution of Registrable Securities under a Shelf
Registration Statement. If a Holder becomes a Notice Holder on or

-7-

 

after the fifth Business Day before the date the Initial Shelf Registration
Statement becomes effective under the Securities Act, the Company shall, as promptly
as practicable after the date such Holder became a Notice Holder, and in any event,
subject to clause (B) below, within the later of (x) ten (10) Business Days after
such date or (y) ten (10) Business Days after the expiration of any Suspension
Period that either (I) is in effect when such Holder became a Notice Holder or (II)
is put into effect within ten (10) Business Days after the date such Holder became a
Notice Holder,

     (A) file with the SEC a supplement to the related Prospectus (or, if
required by law, a post-effective amendment to the Shelf Registration
Statement or a Subsequent Shelf Registration Statement), and all other
document(s), in each case as is required so that such Notice Holder is named
as a selling securityholder in a Shelf Registration Statement and the
related Prospectus in such a manner as to permit such Notice Holder to
deliver a Prospectus to purchasers of the Registrable Securities in
accordance with applicable law; provided, however, that, if
a post-effective amendment or a Subsequent Shelf Registration Statement is
required by the rules and regulations of the SEC in order to permit resales
by such Notice Holder, the Company shall not be required to file more than
one (1) post-effective amendment or Subsequent Shelf Registration Statement
for such purpose in any ninety (90) day period;

     (B) if, pursuant to Section 2(d)(i)(A), the Company shall have filed a
post-effective amendment to the Shelf Registration Statement or filed a
Subsequent Shelf Registration Statement, the Company shall use its
commercially reasonable efforts to cause such post-effective amendment or
Subsequent Shelf Registration Statement, as the case may be, to become
effective under the Securities Act as promptly as practicable, but in any
event by the date (the “Amendment Effectiveness Deadline Date,” in
the case of a post-effective amendment, and the “Subsequent Shelf
Registration Statement Effectiveness Deadline Date,” in the case of a
Subsequent Shelf Registration Statement) that is thirty (30) days after the
date such post-effective amendment or Subsequent Shelf Registration
Statement, as the case may be, is required by this Section 2(d) to be filed
with the SEC;

     (C) the Company shall provide such Notice Holder a reasonable number of
copies of any documents filed pursuant to clause (A) above;

     (D) the Company shall notify such Notice Holder as promptly as
practicable after the effectiveness under the Securities Act of any
post-effective amendment or Subsequent Shelf Registration Statement filed
pursuant to clause (A) above;

-8-

 

     (E) if such Holder became a Notice Holder during a Suspension Period,
or a Suspension Period is put into effect within ten (10) Business Days
after the date such Holder became a Notice Holder, the Company shall so
inform such Notice Holder and shall take the actions set forth in clauses
(A), (B), (C) and (D) above within ten (10) Business Days after expiration
of such Suspension Period in accordance with Section 3(j); and

     (F) if, under applicable law, the Company has more than one option as
to the type or manner of making any such filing, the Company shall make the
required filing or filings in the manner or of a type that is reasonably
expected to result in the earliest availability of a Prospectus for
effecting resales of Registrable Securities.

     (ii) 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
(regardless of when such Holder became a Notice Holder) shall be named as a selling
securityholder in a Shelf Registration Statement or related Prospectus in accordance
with the requirements of this Section 2(d) or Section 2(a), as applicable.

     (e) The parties hereto agree that the Holders of Registrable Securities will suffer
damages, and that it would not be feasible to ascertain the extent of such damages with
precision, if:

     (i) the Initial Shelf Registration Statement has not been filed with the SEC on
or prior to the date that is one hundred twenty (120) days after the Issue Date;

     (ii) the Initial Shelf Registration Statement has not become effective under
the Securities Act on or prior to the Effectiveness Deadline Date;

     (iii) during the Effectiveness Period, the Initial Shelf Registration Statement
or any Subsequent Registration Statement is filed with the SEC and becomes effective
under the Securities Act but shall thereafter cease to be effective (without being
succeeded immediately by a new Registration Statement that is filed and immediately
becomes effective under the Securities Act) or usable for the offer and sale of
Registrable Securities in the manner contemplated by this Agreement for a period of
time (including any Suspension Period) which shall exceed forty-five (45) days in
the aggregate in any three (3) month period or ninety (90) days in the aggregate in
any twelve (12) month period; or

     (iv) any Registration Statement or amendment thereto, at the time it becomes
effective under the Securities Act, or any Prospectus or supplement to a

-9-

 

Prospectus relating thereto, at the time it is filed with the SEC or required
to be filed with the SEC or, if later, at the time the Registration Statement to
which such Prospectus relates becomes effective under the Securities Act, shall fail
to name each Notice Holder as a selling securityholder in such a manner as to permit
such Notice Holder to sell its Registrable Securities pursuant to such Registration
Statement and Prospectus in accordance with applicable law, or shall fail to be
filed as required by Section 2(d), which Notice Holder was entitled, pursuant to the
terms of this Agreement, to be so named (it being understood that, without
limitation, naming such Notice Holder in a manner that permits such Notice Holder to
sell only a portion of such Notice Holder’s Registrable Securities referenced in
such Notice Holder’s Notice and Questionnaire shall be deemed to be an “Event” (as
defined below) for purposes of this clause (iv)) with respect to that portion of
Registrable Securities that is not so permitted to be sold.

Each of the events of a type described in any of the foregoing clauses (i) through (iv) are
individually referred to herein as an “Event,” and

     (W) the date that is one hundred twenty (120) days after the Issue Date, in the
case of clause (i) above,

     (X) the Effectiveness Deadline Date, in the case of clause (ii) above,

     (Y) the date on which the duration of the ineffectiveness or unusability of the
Shelf Registration Statement exceeds the number of days permitted by clause (iii)
above, in the case of clause (iii) above, and

     (Z) the date the applicable Registration Statement or amendment thereto shall
become effective under the Securities Act, or the date the applicable Prospectus or
Prospectus supplement is filed with the SEC or is required to be filed with the SEC
pursuant to Section 2(d) or, if later, the time the Registration Statement to which
such Prospectus relates becomes effective under the Securities Act, as the case may
be, in the case of clause (iv) above,

are each herein referred to as an “Event Date.” Events shall be deemed to continue
until the following dates with respect to the respective types of Events:

     (A) the date the Initial Shelf Registration Statement is filed with the SEC, in
the case of an Event of the type described in clause (i) above;

     (B) the date the Initial Shelf Registration Statement becomes effective under
the Securities Act, in the case of an Event of the type described in clause (ii)
above;

     (C) the date the Initial Shelf Registration Statement or the Subsequent Shelf
Registration Statement, as the case may be, becomes effective and usable again, or
the date another Subsequent Shelf Registration Statement is filed with

-10-

 

the SEC pursuant to Section 2(b) and becomes effective, in the case of an Event
of the type described in clause (iii) above; or

     (D) the date a supplement to the Prospectus is filed with the SEC, or the date
a post-effective amendment to the Registration Statement becomes effective under the
Securities Act, or the date a Subsequent Shelf Registration Statement becomes
effective under the Securities Act, which supplement, post-effective amendment or
Subsequent Shelf Registration Statement, as the case may be, names as selling
securityholders, in such a manner as to permit them to sell their Registrable
Securities pursuant to the Registration Statement and Prospectus supplement in
accordance with applicable law, all Notice Holders entitled as herein provided to be
so named, in the case of an Event of the type described in clause (iv) above.

Accordingly, commencing on (and including) any Event Date and ending on (but excluding) the
next date on which there are no Events that have occurred and are continuing (an
“Additional Interest Accrual Period”), the Company agrees to pay, as additional
interest (“additional interest”) and not as a penalty, an amount (the
“Additional Interest Amount”) at the rate described below, payable periodically on
each Additional Interest Payment Date to Record Holders of Notes, to the extent of, for each
such Additional Interest Payment Date, the unpaid Additional Interest Amount that has
accrued to (but excluding) such Additional Interest Payment Date (or, if the Additional
Interest Accrual Period shall have ended prior to such Additional Interest Payment Date, the
day immediately after the last day of such Additional Interest Accrual Period);
provided, however, that any unpaid Additional Interest Amount that has
accrued with respect to any Note, or portion thereof, called for Redemption on a Redemption
Date, or purchased by the Company pursuant to a Repurchase at Holder’s Option or Repurchase
Upon Repurchase Event on an Option Purchase Date or Repurchase Date, as the case may be,
that is after the close of business on the Record Date relating to such Additional Interest
Payment Date and before such Additional Interest Payment Date, shall, in each case, be
instead paid, on such Redemption Date, Option Purchase Date or Repurchase Date, as the case
may be, to the Holder who submitted such Note or portion thereof for Redemption, Repurchase
at Holder’s Option or Repurchase Upon Repurchase Event, as the case may be;
provided, further, that if a Holder has converted some or all of its Notes
into Common Stock, such Holder will not be entitled to receive Additional Interest with
respect to such Common Stock and the Company will determine the Additional Interest to be
paid with respect to any such converted Note on a pro rata basis based on the date of such
conversion. In addition, in no event will Additional Interest be payable in connection with
a Default relating to a failure to register the Underlying Common Stock. For the avoidance
of doubt, if the Company fails to register both the Notes and the Underlying Common Stock,
Additional Interest will be payable in connection with the Default relating to the failure
to register the Notes.

The Additional Interest Amount shall accrue at a rate per annum equal to one quarter of one
percent (0.25%) for the ninety (90) day period beginning on, and including, the Event Date
and thereafter at a rate per annum equal to one half of one percent (0.50%) of the

-11-

 

aggregate principal amount of the Notes of which such Record Holders were holders of record
at the close of business on the applicable Record Date; provided, however,
that:

     (I) no Additional Interest Amounts shall accrue as to any Note from and after
the earlier of (x) the date such Note is no longer a Registrable Security, (y) the
date, and to the extent, such Note is converted into shares of Common Stock in
accordance with the Indenture and (z) the expiration of the Effectiveness Period;

     (II) only those Holders (or their subsequent transferees) failing to be named
as selling securityholders in the manner prescribed in Section 2(e)(iv) above shall
be entitled to receive any Additional Interest Amounts that have accrued solely with
respect to an Event of the type described in Section 2(e)(iv) above (it being
understood that this clause (II) shall not impair any right of any Holder to receive
Additional Interest Amounts that have accrued with respect to an Event other than an
Event of the type described in Section 2(e)(iv) above); and

     (III) if a Note ceases to be outstanding during an Additional Interest Accrual
Period for which an Additional Interest Amount would be payable with respect to such
Note, then the Additional Interest Amount payable hereunder with respect to such
Note shall be prorated on the basis of the number of full days such Note is
outstanding during such Additional Interest Accrual Period.

Except as provided in the final paragraph of this Section 2(e), (i) the rate of accrual of
the Additional Interest Amount with respect to any period shall not exceed the rate provided
for in this Section 2(e) notwithstanding the occurrence of multiple concurrent Events and
(ii) following the cure of all Events requiring the payment by the Company of Additional
Interest Amounts to the Holders pursuant to this Section, the accrual of Additional Interest
Amounts shall cease (without in any way limiting the effect of any subsequent Event
requiring the payment of Additional Interest Amounts by the Company). All installments of
additional interest shall be paid by wire transfer of immediately available funds to the
account specified by the Notice Holder or, if no such account is specified, by mailing a
check to such Notice Holder’s address shown in the register of the registrar for the Notes
or for the Underlying Common Stock, as the case may be.

All of the Company’s obligations set forth in this Section 2(e) that are outstanding with
respect to any Registrable Security at the time such Registrable Security ceases to be a
Registrable Security shall survive until such time as all such obligations with respect to
such security have been satisfied in full (notwithstanding termination of this Agreement
pursuant to Section 10(n)).

The parties hereto agree that the additional interest provided for in this Section 2(e)
constitutes a reasonable estimate of the damages in respect of the Notes that may be
incurred by Holders of the Notes by reason of an Event relating to the Notes, including,
without limitation, the failure of a Shelf Registration Statement to be filed, become
effective under the Securities Act, amended or replaced to include the names of all Notice

-12-

 

Holders or available for effecting resales of Registrable Securities in accordance with the
provisions hereof. Subject to any rights that may arise pursuant to Section 6 hereof, the
parties hereto also agree that the Company shall have no liability to a Holder of Notes for
monetary damages with respect to an Event relating to such Notes other than the additional
interest provided for in this Section 2(e); provided, however, that nothing
in this paragraph shall impair any rights a holder of Underlying Common Stock may have with
respect to an Event relating to such Underlying Common Stock.

If any Additional Interest Amounts are not paid when due, then, to the extent permitted by
law, such overdue Additional Interest Amounts, if any, shall bear interest, compounded
semi-annually, until paid at the rate of interest payable with respect to overdue amounts on
the Notes pursuant to Section 2.15 of the Indenture.

     (f) The Trustee shall be entitled, on behalf of Holders, to seek any available remedy
for the enforcement of this Agreement, including for the payment of any Additional Interest
Amount.

     3. Registration Procedures. In connection with the registration obligations of the
Company under Section 2 hereof, the Company shall:

     (a) Prepare and file with the SEC a Shelf Registration Statement or Shelf Registration
Statements in the manner provided in this Agreement and use its commercially reasonable
efforts to cause each such Shelf Registration Statement to become effective under the
Securities Act and remain effective under the Securities Act as provided herein;
provided, that, before filing any Shelf Registration Statement or Prospectus or any
amendments or supplements thereto with the SEC, the Company shall furnish to the Initial
Purchaser and counsel for the Holders and for the Initial Purchaser (or, if applicable,
separate counsel for the Holders) copies of all such documents proposed to be filed and
reflect in each such document when so filed with the SEC such comments as the Initial
Purchaser or such counsel reasonably shall propose within three (3) Business Days of the
delivery of such copies to the Initial Purchaser and such counsel. Each Registration
Statement that is or is required by this Agreement to be filed with the SEC shall be filed
on Form S-3 if the Company is then eligible to use Form S-3 for the purposes contemplated by
this Agreement, or, if the Company is not then so eligible to use Form S-3, shall be on Form
S-1 or another appropriate form that is then available to the Company for the purposes
contemplated by this Agreement. Each such Registration Statement that is filed on Form S-3
may, at the option of the Company, be an Automatic Shelf Registration Statement if the
Company is then eligible to file an Automatic Shelf Registration Statement on Form S-3 for
the purposes contemplated by this Agreement. If, at the time any Registration Statement is
filed with the SEC, the Company is eligible, pursuant to Rule 430B(b), to omit, from the
prospectus that is filed as part of such Registration Statement, the identities of selling
securityholders and amounts of securities to be registered on their behalf, then the Company
shall prepare and file such Registration Statement in a manner as to permit such omission
and to allow for the subsequent filing of such information in a prospectus pursuant to Rule
424(b) in the manner contemplated by Rule 430B(d).

-13-

 

     (b) Prepare and file with the SEC such amendments and post-effective amendments to each
Shelf Registration Statement as may be necessary to keep such Shelf Registration Statement
or Subsequent Shelf Registration Statement continuously effective until the expiration of
the Effectiveness Period; cause the related Prospectus to be supplemented by any required
Prospectus supplement and, as so supplemented, to be filed with the SEC pursuant to Rule
424; and comply with the provisions of the Securities Act applicable to it with respect to
the disposition of all securities covered by each Shelf Registration Statement during the
Effectiveness Period in accordance with the intended methods of disposition by the sellers
thereof set forth in such Shelf Registration Statement as so amended or such Prospectus as
so supplemented.

     (c) If, at any time during the Effectiveness Period, any Registration Statement shall
cease to comply with the requirements of the Securities Act with respect to eligibility for
the use of the form on which such Registration Statement was filed with the SEC (or if such
Registration Statement constituted an Automatic Shelf Registration Statement at the time it
was filed with the SEC and shall thereafter cease to constitute an Automatic Shelf
Registration Statement, or if the Company shall have received, from the SEC, a notice,
pursuant to Rule 401(g)(2) under the Securities Act, of objection to the use of the form on
which such Registration Statement was filed with the SEC), (i) promptly give notice to the
Notice Holders and counsel for the Holders and for the Initial Purchaser (or, if applicable,
separate counsel for the Holders) and to the Initial Purchaser and (ii) promptly file with
the SEC a new Registration Statement under the Securities Act, or a post-effective amendment
to such Registration Statement, to effect compliance with the Securities Act if so required.
The Company shall use its commercially reasonable efforts to cause any such new
Registration Statement or post-effective amendment to become effective under the Securities
Act as soon as practicable and shall promptly give notice of such effectiveness to the
Notice Holders and counsel for the Holders and for the Initial Purchaser (or, if applicable,
separate counsel for the Holders) and to the Initial Purchaser. Each such new Registration
Statement, if any, shall be deemed, for purposes of this Agreement, to be a Subsequent Shelf
Registration Statement.

     (d) As promptly as practicable, give notice to the Notice Holders, the Initial
Purchaser and counsel for the Holders and for the Initial Purchaser (or, if applicable,
separate counsel for the Holders):

     (i) when any Prospectus, Prospectus supplement, Shelf Registration Statement or
any post-effective amendment to a Shelf Registration Statement (other than any such
supplement or amendment that does nothing more than name Notice Holders and provide
information with respect thereto) has been filed with the SEC and, with respect to a
Shelf Registration Statement or any post-effective amendment, when the same has
become effective under the Securities Act,

     (ii) of any request, following the effectiveness of a Shelf Registration
Statement under the Securities Act, by the SEC or any other governmental authority
for amendments or supplements to such Shelf Registration Statement or

-14-

 

     the related Prospectus or for additional information,

     (iii) of the issuance by the SEC or any other governmental authority of any
stop order suspending the effectiveness of any Shelf Registration Statement or the
initiation or threatening of any proceedings for that purpose,

     (iv) of the receipt by the Company or its legal counsel of any notification
with respect to the suspension of the qualification or exemption from qualification
of any of the Registrable Securities for sale in any jurisdiction or the initiation
or threatening of any proceeding for such purpose,

     (v) after the effective date of any Shelf Registration Statement filed with the
SEC pursuant to this Agreement, of the occurrence of (but not the nature of or
details concerning) a Material Event, and

     (vi) of the determination by the Company that a post-effective amendment to a
Shelf Registration Statement or a Subsequent Shelf Registration Statement will be
filed with the SEC, which notice may, at the discretion of the Company (or as
required pursuant to Section 3(j)), state that it constitutes a Suspension Notice,
in which event the provisions of Section 3(j) shall apply.

     (e) Use its commercially reasonable efforts to (i) prevent the issuance of, and, if
issued, to obtain the withdrawal of, any order suspending the effectiveness of a Shelf
Registration Statement and (ii) obtain the lifting of any suspension of the qualification
(or exemption from qualification) of any of the Registrable Securities for sale in any
jurisdiction in which they have been qualified for sale, in either case at the earliest
possible moment, and provide prompt notice to each Notice Holder and the Initial Purchaser,
and counsel for the Holders and for the Initial Purchaser (or, if applicable, separate
counsel for the Holders), of the withdrawal or lifting of any such order or suspension.

     (f) If requested by the Initial Purchaser or any Notice Holder, as promptly as
practicable incorporate in a Prospectus supplement or a post-effective amendment to a Shelf
Registration Statement such information as the Initial Purchaser, such Notice Holder or
counsel for the Holders and for the Initial Purchaser (or, if applicable, separate counsel
for the Holders) shall 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, however, that the Company shall not be required to take any
actions under this Section 3(f) that, in the written opinion of counsel for the Company, are
not in compliance with applicable law.

     (g) As promptly as practicable, furnish to each Notice Holder (upon their written
request therefor), counsel for the Holders and for the Initial Purchaser (or, if applicable,
separate counsel for the Holders) and the Initial Purchaser, without charge, at least one
(1) conformed copy of each Shelf Registration Statement and each amendment thereto,
including financial statements but excluding schedules, all documents

-15-

 

incorporated or deemed to be incorporated therein by reference and all exhibits (unless
requested in writing to the Company by such Notice Holder, such counsel or the Initial
Purchaser).

     (h) During the Effectiveness Period, deliver to each Notice Holder, counsel for the
Holders and for the Initial Purchaser (or, if applicable, separate counsel for the Holders)
and the Initial Purchaser, in connection with any sale of Registrable Securities pursuant to
a Shelf Registration Statement, without charge, as many copies of the Prospectus or
Prospectuses relating to such Registrable Securities (including each preliminary prospectus)
and any amendment or supplement thereto as such Notice Holder or the Initial Purchaser may
reasonably request; and the Company hereby consents (except during such periods that a
Suspension Notice is outstanding and has not been revoked) to the use of such Prospectus and
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.

     (i) Prior to any public offering of the Registrable Securities pursuant to a Shelf
Registration Statement, use its commercially reasonable efforts to register or qualify or
cooperate with the Notice Holders in connection with the registration or qualification (or
exemption from such registration or qualification) of such Registrable Securities for offer
and sale under the securities or Blue Sky laws of such jurisdictions within the United
States as any Notice Holder reasonably requests in writing (which request may be included in
the Notice and Questionnaire); use its commercially reasonable efforts to keep each such
registration or qualification (or exemption therefrom) effective during the Effectiveness
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 relevant Shelf
Registration Statement and the related Prospectus; provided, however, that
the Company will not be required to qualify generally to do business in any jurisdiction
where it is not then so qualified.

     (j) Upon: (A) the occurrence or existence of any pending corporate development (a
“Material Event”) that, in the reasonable discretion of the Company, makes it
appropriate to suspend the availability of any Shelf Registration Statement and the related
Prospectus; (B) the issuance by the SEC of a stop order suspending the effectiveness of any
Shelf Registration Statement or the initiation of proceedings with respect to any Shelf
Registration Statement under Section 8(d) or 8(e) of the Securities Act; or (C) the
occurrence of any event or the existence of any fact 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 necessary in order to make the statements therein,
in the light of the circumstances under which they were made, not misleading,

-16-

 

     (i) in the case of clause (A) or (C) above, subject to the next sentence, as
promptly as practicable, prepare and file, if necessary pursuant to applicable law,
a post-effective amendment to such Shelf Registration Statement or a supplement to
such 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 so that such Prospectus does not contain any untrue statement of a
material fact or omit to state any material fact necessary in order 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
a Shelf Registration Statement, subject to the next sentence, use its commercially
reasonable efforts to cause it to become effective under the Securities Act as
promptly as practicable, and

     (ii) give notice to the Notice Holders and counsel for the Holders and for the
Initial Purchaser (or, if applicable, separate counsel for the Holders) and to the
Initial Purchaser that the availability of the Shelf Registration Statement is
suspended (a “Suspension Notice”) (and, upon receipt of any Suspension
Notice, each Notice Holder agrees not to sell any Registrable Securities pursuant to
such 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
such Notice Holder is advised in writing by the Company that the Prospectus may be
used).

The Company will use its commercially reasonable efforts to ensure that the use of the
Prospectus may be resumed (x) in the case of clause (A) above, as soon as, in the reasonable
discretion of the Company, such suspension is no longer appropriate, (y) in the case of
clause (B) above, as promptly as is practicable, and (z) in the case of clause (C) above, as
soon as, in the reasonable judgment of the Company, the 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
the Prospectus does not contain any untrue statement of a material fact or omit to state any
material fact necessary in order to make the statements therein, in the light of the
circumstances under which they were made, not misleading. The period during which the
availability of the Shelf Registration Statement and any Prospectus may be suspended (the
“Suspension Period”) without the Company incurring any obligation to pay additional
interest pursuant to Section 2(e) shall not exceed forty-five (45) days in the aggregate in
any three (3) month period or ninety (90) days in the aggregate in any twelve (12) month
period.

     (k) Make available for inspection during normal business hours by representatives for
the Notice Holders and any underwriters participating in any

-17-

 

disposition pursuant to any Shelf Registration Statement and any broker-dealers,
attorneys and accountants retained by such Notice Holders or any such underwriters, all
relevant financial and other records and pertinent corporate documents and properties of the
Company and its subsidiaries, and cause the appropriate officers, directors and employees of
the Company and its subsidiaries to make available for inspection during normal business
hours all relevant information reasonably requested by such representatives for the Notice
Holders, or any such underwriters, broker-dealers, attorneys or accountants in connection
with such disposition, in each case as is customary for similar “due diligence”
examinations; provided, however, that such persons shall, at the Company’s
request, first agree in writing with the Company that any information that is reasonably and
in good faith designated by the Company in writing as confidential at the time of delivery
of such information shall be kept confidential by such persons and shall be used solely for
the purposes of exercising rights under this Agreement, unless (i) disclosure of such
information is required by court or administrative order or is necessary to respond to
inquiries of governmental or regulatory authorities, (ii) disclosure of such information is
required by law (including any disclosure requirements pursuant to federal securities laws
in connection with the filing of any Shelf Registration Statement or the use of any
Prospectus referred to in this Agreement) or necessary to defend or prosecute a claim
brought against or by any such persons (e.g., to establish a “due diligence” defense), (iii)
such information becomes generally available to the public other than as a result of a
disclosure or failure to safeguard by any such person or (iv) such information becomes
available to any such person from a source other than the Company and such source is not
bound by a confidentiality agreement or is not otherwise under a duty of trust to the
Company; provided further, that the foregoing inspection and information
gathering shall, to the greatest extent possible, be coordinated on behalf of all the Notice
Holders and the other parties entitled thereto by the counsel, referred to in Section 5, for
the Holders in connection with Shelf Registration Statements.

     (l) Comply with all applicable rules and regulations of the SEC; and make generally
available to its securityholders earnings 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), which statements shall cover a period of
twelve (12) months commencing on the first day of the first fiscal quarter of the Company
commencing after the effective date of each Shelf Registration Statement (within the meaning
of Rule 158(c) under the Securities Act), and which statements shall be so made generally
available to the Company’s securityholders as follows: (i) with respect to an earnings
statement which will be contained in one report on Form 10-K (or any other form as may then
be available for such purpose), such earnings statement shall be made so generally available
no later than the due date by which the Company is required, pursuant to the Exchange Act,
to file such report with the SEC; and (ii) with respect to an earnings statement which will
be contained in any combination of reports on Form 10-K or Form 10-Q (or any other form(s)
as may then be available for such purpose), such earnings statement shall be made so
generally available no later than the due date by which the Company is required, pursuant to
the Exchange Act, to file the last of such reports which together constitute such earnings
statement.

-18-

 

     (m) Cooperate with each Notice Holder to facilitate the timely preparation and delivery
of certificates representing Registrable Securities sold pursuant to a Shelf Registration
Statement, which certificates shall not bear any restrictive legends, and cause such
Registrable Securities to be in such denominations as are permitted by the Indenture and
registered in such names as such Notice Holder may request in writing at least five (5)
Business Days prior to any sale of such Registrable Securities.

     (n) Provide a CUSIP number for all Registrable Securities covered by a Shelf
Registration Statement not later than the effective date of the Initial Shelf Registration
Statement and provide the Trustee and the transfer agent for the Common Stock with
certificates for the Registrable Securities that are in a form eligible for deposit with The
Depository Trust Company (“DTC”).

     (o) Cooperate and assist in any filings required to be made with the National
Association of Securities Dealers, Inc.

     (p) Promptly following the filing of the Initial Shelf Registration Statement, and upon
the effectiveness under the Securities Act of the Initial Shelf Registration Statement,
announce the same, in each case by release through a reputable national newswire service.

     (q) In connection with an underwritten offering of Registrable Securities, take all
actions and enter into such customary agreements (including, if requested, an underwriting
agreement in customary form) as are necessary, or reasonably requested by the Holders of a
majority of the Registrable Securities being sold, in order to expedite or facilitate
disposition of such Registrable Securities; and in such connection, whether or not an
underwriting agreement is entered into:

     (i) the Company shall make such representations and warranties to the Holders
of such Registrable Securities and the underwriters in form, substance and scope as
would be customarily made by the Company to underwriters in similar offerings of
securities;

     (ii) the Company shall obtain opinions of counsel of the Company and updates
thereof (which counsel and opinions (in form, scope and substance) shall be
reasonably satisfactory to the Managing Underwriters, if any, and to the counsel to
the Holders of the Registrable Securities being sold) addressed to each selling
Holder and the underwriters, if any, covering the matters that would be customarily
covered in opinions requested in sales of securities or underwritten offerings;

     (iii) the Company shall obtain “comfort letters” and updates thereof from the
Company’s independent certified public accountants (and, if necessary, any other
independent certified public accountants of any subsidiary of the Company or of any
business acquired by the Company for which financial statements are, or are required
to be, included in any Shelf Registration

-19-

 

Statement) addressed to the underwriters, if any, and the selling Holders of
Registrable Securities (to the extent consistent with Statement on Auditing
Standards No. 72, AU 634 or such other professional standards of the American
Institute of Certified Public Accountants as may be applicable), such letters to be
in customary form and covering matters of the type that would customarily be covered
in “comfort letters” to underwriters in connection with similar underwritten
offerings;

     (iv) the Company shall, if an underwriting agreement is entered into, cause any
such underwriting agreement to contain indemnification provisions and procedures
substantially equivalent to the indemnification provisions and procedures set forth
in Section 6 hereof with respect to the underwriters and all other parties to be
indemnified pursuant to said Section; and

     (v) the Company shall deliver such documents and certificates as may be
reasonably requested and as are customarily delivered in similar offerings to the
holders of a majority of the Registrable Securities being sold and to the Managing
Underwriters, if any;

     the above to be done at (x) the effectiveness of any Shelf Registration Statement (and each
post-effective amendment thereto) and (y) each closing under any underwriting or similar
agreement as and to the extent required thereunder. In no event shall the Company be
required to conduct more than one underwritten offering of the Registrable Securities.

     (r) Cause the Indenture to be qualified under the TIA not later than the effective date
of the Initial Shelf Registration Statement; and, in connection therewith, cooperate with
the Trustee to effect such changes to the Indenture as may be required for the Indenture to
be so qualified in accordance with the terms of the TIA and execute, and use its
commercially reasonable efforts to cause the Trustee to execute, all documents as may be
required to effect such changes, and all other forms and documents required to be filed with
the SEC to enable the Indenture to be so qualified in a timely manner.

     (s) Use its reasonable best efforts to cause the Underlying Common Stock to be listed
on The Nasdaq National Market.

     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 a 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(d) 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 the Company may from time to time reasonably request. Any sale of

-20-

 

any Registrable Securities by any Holder shall constitute a representation and warranty by
such Holder that the Holder Information of such Holder furnished in writing by or on behalf of such
Holder to the Company does not include an untrue statement of a material fact or omit to state a
material fact necessary in order to make the statements in such Holder Information, in the light of
the circumstances under which they were made, not misleading.

     5. Registration Expenses. The Company shall bear all fees and expenses incurred in
connection with the performance by the Company of its obligations under Section 2 and Section 3 of
this Agreement whether or not any of the Shelf Registration Statements are filed or declared
effective under the Securities Act. Such fees and expenses (“Registration Expenses”) shall
include, without limitation, (i) all registration and filing fees and expenses (including, without
limitation, fees and expenses (x) with respect to filings required to be made with the National
Association of Securities Dealers, Inc. and (y) of compliance with federal securities laws and
state securities or Blue Sky laws (including, without limitation, reasonable fees and disbursements
of counsel for the Holders in connection with Blue Sky qualifications of the Registrable Securities
under the laws of such jurisdictions as the Notice Holders of a majority of the Registrable
Securities being sold pursuant to a Shelf Registration Statement may designate), (ii) all printing
expenses (including, without limitation, expenses of printing certificates for Registrable
Securities in a form eligible for deposit with The Depository Trust Company and printing
Prospectuses), (iii) all duplication and mailing expenses relating to copies of any Shelf
Registration Statement or Prospectus delivered to any Holders hereunder, (iv) all fees and
disbursements of counsel for the Company and the fees and disbursements of one counsel for the
Holders in connection with the Shelf Registration Statement, (v) all fees and disbursements of the
Trustee and its counsel and of the registrar and transfer agent for the Common Stock and (vi)
Securities Act liability insurance obtained by the Company in its sole discretion. In addition, the
Company shall pay the internal expenses of the Company (including, without limitation, all salaries
and expenses of officers and employees performing legal or accounting duties), the expense of any
annual audit or quarterly review, the fees and expenses incurred in connection with the listing by
the Company of the Registrable Securities on any securities exchange or quotation system on which
similar securities of the Company are then listed and the fees and expenses of any person,
including, without limitation, special experts, retained by the Company. If the Company shall,
pursuant to Rule 456(b), defer payment of any registration fees due under the Securities Act with
respect to any Registration Statement, the Company agrees that it shall pay the fees applicable to
such Registration Statement within the time required by Rule 456(b)(1)(i) (without reliance on the
proviso to Rule 456(b)(1)(i)) and in compliance with Rule 456(b) and Rule 457(r).

     6. Indemnification, Contribution.

     (a) The Company agrees to indemnify, defend and hold harmless the Initial Purchaser,
each Holder, each person (a “Controlling Person”), if any, who controls the Initial
Purchaser or any Holder within the meaning of Section 15 of the Securities Act or Section 20
of the Exchange Act and the respective officers, directors, partners, employees,
representatives and agents of the Initial Purchaser, the Holders or any Controlling Person
(each, an “Indemnified Party”), from and against any loss, damage, expense,
liability, claim or any actions in respect thereof (including the reasonable cost of

-21-

 

investigation) which such Indemnified Party may incur or become subject to under the
Securities Act, the Exchange Act or otherwise, insofar as such loss, damage, expense,
liability, claim or action arises out of or is based upon any untrue statement or alleged
untrue statement of a material fact contained in any Shelf Registration Statement or
Prospectus, including any document incorporated by reference therein, or in any amendment or
supplement thereto or in any preliminary prospectus, or arises out of or is based upon any
omission or alleged omission to state a material fact required to be stated in any Shelf
Registration Statement or in any amendment or supplement thereto or necessary to make the
statements therein not misleading, or arises out of or is based upon any omission or alleged
omission to state a material fact necessary in order to make the statements made in any
Prospectus or in any amendment or supplement thereto or in any preliminary prospectus, in
the light of the circumstances under which such statements were made, not misleading, and
the Company shall reimburse, as incurred, the Indemnified Parties for any legal or other
expenses reasonably incurred by them in connection with investigating or defending any such
loss, damage, expense, liability, claim or action in respect thereof; provided,
however, that the Company shall not be required to provide any indemnification
pursuant to this Section 6(a) in any such case insofar as any such loss, damage, expense,
liability, claim or action arises out of or is based upon any untrue statement or omission
or alleged untrue statement or omission of a material fact contained in, or omitted from,
and in conformity with information furnished in writing by or on behalf of the Initial
Purchaser or a Holder to the Company expressly for use in, any Shelf Registration Statement
or any Prospectus; provided further, however, that this indemnity
agreement will be in addition to any liability which the Company may otherwise have to such
Indemnified Party.

     (b) Each Holder, severally and not jointly, agrees to indemnify, defend and hold
harmless the Company, its directors, officers, employees and any person who controls the
Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange
Act (each, a “Company Indemnified Party”) from and against any loss, damage,
expense, liability, claim or any actions in respect thereof (including the reasonable cost
of investigation) which such Company Indemnified Party may incur or become subject to under
the Securities Act, the Exchange Act or otherwise, insofar as such loss, damage, expense,
liability, claim or action arises out of or is based upon any untrue statement or alleged
untrue statement of a material fact contained in, and in conformity with information (the
“Holder Information”) furnished in writing by or on behalf of such Holder to the
Company expressly for use in, any Shelf Registration Statement or Prospectus, or arises out
of or is based upon any omission or alleged omission to state a material fact in connection
with such Holder Information, which material fact was not contained in such Holder
Information, and which material fact was either required to be stated in any Shelf
Registration Statement or Prospectus or necessary to make such Holder Information not
misleading; and, subject to the limitation set forth in the immediately preceding clause,
each Holder shall reimburse, as incurred, the Company for any legal or other expenses
reasonably incurred by the Company or any such controlling person in connection with
investigating or defending any loss, damage, expense, liability, claim or action in respect
thereof. This indemnity agreement will be in addition to any liability which such Holder
may otherwise have to the Company or any of

-22-

 

its controlling persons. In no event shall the liability of any selling Holder of
Registrable Securities hereunder be greater in amount than the dollar amount of the proceeds
received by such Holder upon the sale, pursuant to the Shelf Registration Statement, of the
Registrable Securities giving rise to such indemnification obligation.

     (c) If any action, suit or proceeding (each, a “Proceeding”) is brought against
any person in respect of which indemnity may be sought pursuant to either Section 6(a) or
Section 6(b), such person (the “Indemnified Party”) shall promptly notify the person
against whom such indemnity may be sought (the “Indemnifying Party”) in writing of
the institution of such Proceeding and the Indemnifying Party shall assume the defense of
such Proceeding; provided, however, that the omission to so notify such
Indemnifying Party shall not relieve such Indemnifying Party from any liability which it may
have to such Indemnified Party or otherwise. Such Indemnified Party shall have the right to
employ its own counsel in any such case, but the fees and expenses of such counsel shall be
at the expense of such Indemnified Party unless the employment of such counsel shall have
been authorized in writing by such Indemnifying Party in connection with the defense of such
Proceeding or such Indemnifying Party shall not have employed counsel to have charge of the
defense of such Proceeding within thirty (30) days of the receipt of notice thereof or such
Indemnified Party shall have reasonably concluded upon the written advice of counsel that
there may be one or more defenses available to it that are different from, additional to or
in conflict with those available to such Indemnifying Party (in which case such Indemnifying
Party shall not have the right to direct that portion of the defense of such Proceeding on
behalf of the Indemnified Party, but such Indemnifying Party may employ counsel and
participate in the defense thereof but the fees and expenses of such counsel shall be at the
expense of such Indemnifying Party), in any of which events such reasonable fees and
expenses shall be borne by such Indemnifying Party and paid as incurred (it being
understood, however, that such Indemnifying Party shall not be liable for the expenses of
more than one separate counsel in any one Proceeding or series of related Proceedings
together with reasonably necessary local counsel representing the Indemnified Parties who
are parties to such action). An Indemnifying Party shall not be liable for any settlement
of such Proceeding effected without the written consent of such Indemnifying Party, but if
settled with the written consent of such Indemnifying Party, such Indemnifying Party agrees
to indemnify and hold harmless an Indemnified Party from and against any loss or liability
by reason of such settlement. Notwithstanding the foregoing sentence, if at any time an
Indemnified Party shall have requested an Indemnifying Party to reimburse such Indemnified
Party for fees and expenses of counsel as contemplated by the second sentence of this
paragraph, then such Indemnifying Party agrees that it shall be liable for any settlement of
any Proceeding effected without its written consent if (i) such settlement is entered into
more than sixty (60) Business Days after receipt by such Indemnifying Party of the aforesaid
request, (ii) such Indemnifying Party shall not have fully reimbursed such Indemnified Party
in accordance with such request prior to the date of such settlement and (iii) such
Indemnified Party shall have given such Indemnifying Party at least thirty (30) days’ prior
notice of its intention to settle. No Indemnifying Party shall, without the prior written
consent of any Indemnified Party, effect any settlement of any pending or threatened
Proceeding in respect of which such Indemnified Party is or could have been a

-23-

 

party and indemnity could have been sought hereunder by such Indemnified Party, unless
such settlement includes an unconditional release of such Indemnified Party from all
liability on claims that are the subject matter of such Proceeding and does not include an
admission of fault or culpability or a failure to act by or on behalf of such Indemnified
Party.

     (d) If the indemnification provided for in this Section 6 is unavailable to an
Indemnified Party under Section 6(a) or Section 6(b), or insufficient to hold such
Indemnified Party harmless, in respect of any losses, damages, expenses, liabilities, claims
or actions referred to therein, then each applicable Indemnifying Party, in lieu of
indemnifying such Indemnified Party, shall contribute to the amount paid or payable by such
Indemnified Party as a result of such losses, damages, expenses, liabilities, claims or
actions (i) in such proportion as is appropriate to reflect the relative benefits received
by the Company, on the one hand, and by the Holders or the Initial Purchaser, on the other
hand, from the offering of the Registrable Securities 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, on the one hand, and of the Holders or the Initial Purchaser, on the
other hand, in connection with the statements or omissions which resulted in such losses,
damages, expenses, liabilities, claims or actions, as well as any other relevant equitable
considerations. The relative fault of the Company, on the one hand, and of the Holders or
the Initial Purchaser, on the other hand, shall be determined by reference to, among other
things, whether the untrue statement or alleged untrue statement of a material fact or
omission or alleged omission relates to information supplied by the Company or by the
Holders or the Initial Purchaser and the parties’ relative intent, knowledge, access to
information and opportunity to correct or prevent such statement or omission. The amount
paid or payable by a party as a result of the losses, damages, expenses, liabilities, claims
and actions referred to above shall be deemed to include any reasonable legal or other fees
or expenses reasonably incurred by such party in connection with investigating or defending
any Proceeding.

     (e) The Company, the Holders and the Initial Purchaser agree that it would not be just
and equitable if contribution pursuant to this Section 6 were determined by pro rata
allocation or by any other method of allocation which does not take account of the equitable
considerations referred to in Section 6(d) above. Notwithstanding the provisions of this
Section 6, no Holder shall be required to contribute any amount in excess of the amount by
which the total price at which the Registrable Securities giving rise to such contribution
obligation and sold by such Holder were offered to the public exceeds the amount of any
damages which it has otherwise been required to pay by reason of such 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. The Holders’ respective obligations to contribute pursuant to this
Section 6 are several in proportion to the respective amount of Registrable Securities they
have sold pursuant to a Shelf Registration Statement, and not joint. The remedies provided
for in this Section 6 are not exclusive and shall not limit

-24-

 

any rights or remedies which may otherwise be available to any indemnified party at law
or in equity.

     (f) The indemnity and contribution provisions contained in this Section 6 shall remain
operative and in full force and effect regardless of (i) any termination of this Agreement,
(ii) any investigation made by or on behalf of any Holder or the Initial Purchaser or any
person controlling any Holder or the Initial Purchaser, or the Company, or the Company’s
officers or directors or any person controlling the Company and (iii) the sale of any
Registrable Security by any Holder.

     7. Information Requirements.

     (a) The Company covenants that, if at any time before the end of the Effectiveness
Period it is not subject to the reporting requirements of the Exchange Act, it will
reasonably cooperate with any Holder of Registrable Securities and take such further action
as any Holder of Registrable Securities may reasonably request in writing (including,
without limitation, making such representations as any such Holder 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 limitations of the
exemptions provided by Rule 144, Rule 144A, Regulation S and Regulation D under the
Securities Act and customarily taken in connection with sales pursuant to such exemptions.
Upon the written request of any Notice Holder, the Company shall deliver to such Notice
Holder a written statement as to whether the Company has complied with the reporting
requirements of the Exchange Act, unless such a statement has been included in the Company’s
most recent report filed with the SEC pursuant to Section 13 or Section 15(d) of Exchange
Act. Notwithstanding the foregoing, nothing in this Section 7 shall be deemed to require the
Company to register any of its securities (other than the Common Stock) under any section of
the Exchange Act.

     (b) The Company shall file the reports required to be filed by it under the Exchange
Act and shall comply with all other requirements set forth in the instructions to Form S-3
in order to allow the Company to be eligible to file registration statements on Form S-3.
The Company shall use its commercially reasonable efforts to remain eligible, pursuant to
Rule 430B(b), to omit, from the prospectus that is filed as part of a Registration
Statement, the identities of selling securityholders and amounts of securities to be
registered on their behalf.

     8. Underwritten Registrations.

     (a) If any of the Registrable Securities covered by the Shelf Registration Statement
are to be offered and sold in an underwritten offering, the investment banker or investment
bankers and manager or managers that will administer the offering (“Managing
Underwriters”) shall be selected by the holders of a majority of such Registrable
Securities to be included in such offering and consented to in writing by the Company, such
consent not to be unreasonably withheld.

-25-

 

     (b) No person may participate in any underwritten registration hereunder unless such
person (i) agrees to sell such person’s Registrable Securities on the basis reasonably
provided in any underwriting arrangements approved by the persons entitled hereunder to
approve such arrangements and (ii) completes and executes all questionnaires, powers of
attorney, indemnities, underwriting agreements and other documents reasonably required under
the terms of such underwriting arrangements.

     9. Applicability of Certain Provisions. Notwithstanding anything herein to the
contrary, so long as the Company is permitted under Rule 430B and other applicable rules and
regulations of the SEC to add the names of selling securityholders or information relating thereto
to the Initial Shelf Registration Statement or any Subsequent Shelf Registration Statement by means
of a Prospectus supplement, nothing in this Agreement shall be construed to require the Company to
add such names or information by other means, including, but not limited to, any post-effective
amendment to such Initial Shelf Registration Statement or any Subsequent Shelf Registration
Statement.

     10. Miscellaneous.

     (a) Remedies. The Company acknowledges and agrees that any failure by the
Company to comply with its obligations under this Agreement may result in material
irreparable injury to the Initial Purchaser and the Holders for which there is no adequate
remedy at law, that it will not be possible to measure damages for such injuries precisely
and that, in the event of any such failure, the Initial Purchaser or any Holder may obtain
such relief as may be required to specifically enforce the Company’s obligations under this
Agreement. The Company further agrees to waive the defense in any action for specific
performance that a remedy at law would be adequate. Notwithstanding the foregoing two
sentences, this Section 10(a) shall not apply to the subject matter referred to in and
contemplated by Section 2(e).

     (b) No Conflicting Agreements. The Company is not, as of the date hereof, a
party to, nor shall it, on or after the date of this Agreement, enter into, any agreement
with respect to the Company’s securities that conflicts with the rights granted to the
Holders in this Agreement. The Company represents and warrants that the rights granted to
the Holders hereunder do not in any way conflict with the rights granted to the holders of
the Company’s securities under any other agreements. The Company will not take any action
with respect to the Registrable Securities which would adversely affect the ability of any
of the Holders to include such Registrable Securities in a registration undertaken pursuant
to this Agreement. The Company represents and covenants that it has not granted, and shall
not grant, to any of its securityholders (other than the Holders in such capacity) the right
to include any of the Company’s securities in any Shelf Registration Statement filed
pursuant to this Agreement.

     (c) Amendments and Waivers. The provisions of this Agreement, including the
provisions of this sentence, 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 Holders of a majority of outstanding

-26-

 

Registrable Securities; provided, however, that, no consent is
necessary from any of the Holders in the event that this Agreement is amended, modified or
supplemented for the purpose of curing any ambiguity, defect or inconsistency that does not
adversely affect the rights of any 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 of Registrable Securities whose securities are being
sold pursuant to a Shelf Registration Statement and that does not directly or indirectly
affect the rights of other Holders of Registrable Securities may be given by Holders of at
least a majority of the Registrable Securities being sold by such Holders pursuant to such
Shelf Registration Statement; provided, however, that the provisions of this
sentence may not be amended, modified, or supplemented except in accordance with the
provisions of the immediately preceding sentence. Each Holder of Registrable Securities
outstanding at the time of any such amendment, modification, supplement, waiver or consent
or thereafter shall be bound by any such amendment, modification, supplement, waiver or
consent effected pursuant to this Section 10(c), whether or not any notice, writing or
marking indicating such amendment, modification, supplement, waiver or consent appears on
the Registrable Securities or is delivered to such Holder.

     (d) Notices. All notices and other communications provided for or permitted
hereunder shall be made in writing by hand delivery, by telecopier, by courier guaranteeing
overnight delivery or by first-class mail, return receipt requested, and shall be deemed
given (A) when made, if made by hand delivery, (B) upon confirmation, if made by telecopier,

courier or (D) on the date indicated on the notice of receipt, if made by first-class mail,

     (e) Majority of Registrable Securities. For purposes of determining what
constitutes holders of a majority of Registrable Securities, as referred to in this
Agreement, a majority shall constitute a majority in aggregate principal amount of
Registrable Securities, treating each relevant holder of shares of Underlying Common Stock
as a holder of the aggregate principal amount of Notes in respect of which such Common Stock
was issued.

     (f) Approval of Holders. Whenever the consent or approval of Holders of a
