or more instruments of substantially similar tenor signed by such Holders in person or by agent
duly appointed in writing and, except as herein otherwise expressly provided, such action shall
become effective when such instrument or instruments are delivered to the Trustee and, where it is
hereby expressly required, to the Company. Such instrument or instruments (and the action embodied
therein and evidenced thereby) are herein sometimes referred to as an “Act” of the Holders signing

appointing any such agent shall be sufficient for any purpose of this Indenture and (subject to
Section 8.01) conclusive in favor of the Trustee and the Company, if made in the manner provided in
this Section 1.04.

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

(c) The Company may, in the circumstances permitted by the Trust Indenture Act, fix any day as
the record date for the purpose of determining the Holders entitled to give or take any request,
demand, authorization, direction, notice, consent, waiver or other action, or to vote on any
action, authorized or permitted to be given or taken by Holders. If not set by the Company prior
to the first solicitation of a Holder made by any Person in respect of any such action, or, in the

30th day (or, if later, the date of the most recent list of Holders required to be provided
pursuant to Section 9.01) prior to such first solicitation or vote, as the case may be. With
regard to any record date, only the Holders on such date (or their duly designated proxies) shall
be entitled to give or take, or vote on, the relevant action.

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

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

(i) the Trustee by any Holder or by the Company shall be sufficient for every purpose
hereunder if made, given, furnished or filed in writing to or with the Trustee at its
applicable Corporate Trust Office; or

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

Section 1.06. Notice to Holders; Waiver. Where this Indenture provides for notice to
Holders of any event, such notice shall be sufficiently given (unless otherwise herein expressly
provided) if in writing and mailed, first-class postage prepaid, to each Holder affected by such
event, at such Holder’s address as it appears in the Security Register, not later than the latest
date (if any), and not earlier than the earliest date (if any), prescribed for the giving of such
notice. In any case where notice to Holders is given by mail, neither the failure to mail such
notice, nor any defect in any notice so mailed, to any particular Holder shall affect the
sufficiency of such notice with respect to other Holders. Notices will be deemed to have been
given on the date of mailing. Where this Indenture provides for notice in any manner, such notice
may be waived in writing by the Person entitled to receive such notice, either before or after the
event, and such waiver shall be the equivalent of such notice. Waivers of notice by Holders shall
be filed with the Trustee, but such filing shall not be a condition precedent to the validity of
any action taken in reliance upon such waiver.

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

Whenever under this Indenture the Trustee is required to provide any notice by mail, in all
cases the Trustee may alternatively provide notice by overnight courier or by telefacsimile, with
confirmation of transmission.

Section 1.07. Conflict with Trust Indenture Act. If any provision hereof limits, qualifies
or conflicts with a provision of the Trust Indenture Act that is required hereunder to be a part of
and govern this Indenture, the latter provision shall control. If any provision of this Indenture
modifies or excludes any provision of the Trust Indenture Act that may be so modified or excluded,
the latter provision shall be
deemed to apply to this Indenture as so modified or to be excluded, as the case may be.

Section 1.08. Effect of Headings and Table of Contents. The Article and Section headings
herein and the Table of Contents are for convenience only and shall not affect the construction
hereof, and all Article and Section references are to Articles and Sections, respectively, of this
Indenture unless otherwise expressly stated.

Section 1.09. Severability Clause. In case any provision in this Indenture or in the
Securities shall be invalid, illegal or unenforceable, the validity, legality and enforceability of
the remaining provisions shall not in any way be affected or impaired thereby.

Section 1.10. Benefits of Indenture. Nothing in this Indenture or in the Securities,
express or implied, shall give to any Person, other than the parties hereto and their respective
successors hereunder and the Holders of Securities, any benefit or any legal or equitable right,
remedy or claim under this Indenture.

construed in accordance with the laws of the State of New York.

for the Company by manual or facsimile signature.

If an Officer whose signature is on a Security no longer holds that office at the time the
Trustee authenticates the Security, the Security shall be valid nevertheless.

A Security shall not be valid until an authorized signatory of the Trustee manually signs the
certificate of authentication on the Security. The signature shall be conclusive evidence that the
Security has been authenticated under this Indenture.

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

Section 2.05. Security Registrar, Paying Agent and Conversion Agent. The Company shall
maintain an office or agency where Securities may be presented for registration of transfer or for
exchange (the “Security Registrar”), an office or agency where Securities may be presented for
payment (the “Paying Agent”) and an office or agency where Securities may be presented for
conversion (the “Conversion Agent”). The Corporate Trust Office shall be considered as one such
office or agency of the Company for each of the aforesaid purposes. The Security Registrar shall
keep a register of the Securities (the “Security Register”) and of their transfer and exchange.
The Company may have one or more co-registrars and one or more additional paying agents. The term
“Paying Agent” includes any additional paying agent, and the term “Security Registrar” includes any
co-registrars. The Company initially appoints the Trustee as (i) Security Registrar and Paying
Agent in connection with the Securities, (ii) the custodian with respect to the Global Securities
and (iii) Conversion Agent.

The Company shall enter into an appropriate agency agreement with any Security Registrar,
Paying Agent or Conversion Agent not a party to this Indenture, which shall incorporate the terms
of the TIA. The agreement shall implement the provisions of this Indenture that relate to such
agent. The Company shall notify the Trustee of the name and address of any such agent. If the
Company fails to maintain a Security Registrar, Paying Agent or Conversion Agent, the Trustee shall
act as such and shall be entitled to appropriate compensation therefor pursuant to Section 8.07.
The Company or any of its domestically organized Wholly Owned Subsidiaries may act as Paying Agent,
Conversion Agent or Security Registrar.

 

19

 

The Company may remove any Security Registrar, Paying Agent or Conversion Agent upon written
notice to such Security Registrar, Paying Agent or
Conversion Agent and to the Trustee; provided that no such removal shall become effective
until (1) acceptance of an appointment by a successor as evidenced by an appropriate agreement
entered into by the Company and such successor Security Registrar, Paying Agent or Conversion
Agent, as the case may be, and delivered to the Trustee or (2) notification to the Trustee that the
Trustee shall serve as Security Registrar, Paying Agent or Conversion Agent until the appointment
of a successor in accordance with clause (1) above. The Security Registrar, Paying Agent or
Conversion Agent may resign at any time upon written notice; provided that the Trustee may resign
as Paying Agent, Conversion Agent or Security Registrar only if the Trustee also resigns as Trustee
in accordance with Section 8.11.

Section 2.06. Paying Agent to Hold Money in Trust. On or prior to each due date of the
principal and interest on any Security, the Company shall deposit with the Paying Agent (or if the
Company or a Wholly Owned Subsidiary of the Company is acting as Paying Agent, segregate and hold
in trust for the benefit of the Persons entitled thereto) a sum sufficient to pay such principal
and interest when so becoming due. The Company shall require each Paying Agent (other than the
Trustee) to agree in writing that the Paying Agent shall hold in trust for the benefit of
Securityholders or the Trustee all money held by the Paying Agent for the payment of principal of
or interest on the Securities and shall notify the Trustee of any default by the Company in making
any such payment. If the Company or a Wholly Owned Subsidiary of the Company acts as Paying Agent,
it shall segregate the money held by it as Paying Agent and hold it as a separate trust fund. The
Company at any time may require a Paying Agent to pay all money held by it to the Trustee and to
account for any funds disbursed by the Paying Agent. Upon complying with this Section 2.06, the
Paying Agent shall have no further liability for the money delivered to the Trustee.

Section 2.07. 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 Security Registrar, the Company shall furnish, or cause
the Security Registrar to furnish, to the Trustee, in writing at least five Business Days before
each Interest Payment Date and at such other times as the Trustee may request in writing, a list in
such form and as of such date as the Trustee may reasonably require of the names and addresses of
Securityholders.

Section 2.08. Exchange And Registration of Transfer of Securities. The Company shall cause
to be kept at the Corporate Trust Office the Security Register in which, subject to such reasonable
regulations as it may prescribe, the Company shall provide for the registration of Securities and
of transfers of Securities. The Security Register shall be in written form or in any form capable
of being converted into written form within a reasonably prompt period of time.

Upon surrender for registration of transfer of any Securities to the Security Registrar or any
co-registrar, and satisfaction of the requirements for such transfer set forth in this Section 2.08
and in Section 2.10, the Company shall execute, and the Trustee shall authenticate and deliver, in
the name of the designated transferee or
transferees, one or more new Securities of any authorized denominations and of a like
aggregate principal amount and bearing such restrictive legends as may be required by this
Indenture.

 

20

 

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

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

All Securities presented or surrendered for registration of transfer or for exchange,
repurchase or conversion shall (if so required by the Company or the Security Registrar) be duly
endorsed, or be accompanied by a written instrument or instruments of transfer in form satisfactory
to the Company, duly executed by the Holder thereof or his attorney duly authorized in writing.

No service charge shall be made to any Holder for any registration of, transfer or exchange of
Securities, but the Company may require payment by the Holder of a sum sufficient to cover any tax,
assessment or other governmental charge that may be imposed in connection with any registration of
transfer or exchange of Securities.

Neither the Company nor the Trustee nor any Security Registrar shall be required to exchange,
issue or register a transfer of (a) any Securities or portions thereof surrendered for conversion
pursuant to Article 5 or (b) any Securities or portions thereof tendered for repurchase (and not
withdrawn) pursuant to Section 4.01.

Section 2.09. Global Securities. The following provisions shall apply to Global Securities:

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

 

21

 

(b) Notwithstanding any other provision in this Indenture, no Global Security may be exchanged
in whole or in part for Securities registered, and no transfer of a Global Security in whole or in
part may be registered, in the name of any
Person other than the Depositary or a nominee thereof unless (A) the Depositary (x) has
notified the Company that it is unwilling or unable to continue as Depositary for such Global
Security or (y) has ceased to be a clearing agency registered under the Exchange Act, and a
successor depositary has not been appointed by the Company within 90 calendar days, or (B) the
Company, in its sole discretion, notifies the Trustee in writing that it no longer wishes to have
all the Securities represented by Global Securities. Any Global Securities exchanged pursuant to
this Section 2.09(b) shall be so exchanged in whole and not in part.

(c) In addition, Physical Securities will be issued in exchange for beneficial interests in a
Global Security upon request by or on behalf of the Depositary in accordance with customary
procedures following the request of a beneficial owner seeking to enforce its rights under the
Securities or this Indenture upon the occurrence and during the continuance of an Event of Default.

(d) Securities issued in exchange for a Global Security or any portion thereof pursuant to
Section 2.09(b) or Section 2.09(c) shall be issued in definitive, fully registered form, without
interest coupons, shall have an aggregate principal amount equal to that of such Global Securities
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 any legends required hereunder. Any
Global Securities to be exchanged shall be surrendered by the Depositary to the Trustee, as
Security Registrar, provided that pending completion of the exchange of a Global Security, the
Trustee acting as custodian for the Global Securities for the Depositary or its nominee with
respect to such Global Securities, shall reduce the principal amount thereof, 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 make
available for delivery the Securities issuable on such exchange to or upon the written order of the
Depositary or an authorized representative thereof.

(e) In the event of the occurrence of any of the events specified in Section 2.09(b) above or
upon any request described in Section 2.09(c), the Company will promptly make available to the
Trustee a sufficient supply of Physical Securities in definitive, fully registered form, without
interest coupons.

(f) Neither any members of, or participants in, the Depositary (“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 Securities registered in the name of the Depositary or any nominee thereof,
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
Securities 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 Securities.

 

22

 

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

Section 2.10. Transfer Restrictions. Until the first anniversary of the Issue Date, (1) any
certificate evidencing a Security shall bear a legend in substantially the form identified as the
“Restricted Security Legend” (the “Restricted Security Legend”) in the form of Security set forth
in Exhibit A and (2) any certificate representing Common Stock issued upon conversion of the
Securities shall bear a legend in substantially the form of Exhibit B, unless such Security (or
such Common Stock) has been sold pursuant to a registration statement that has been declared
effective under the Securities Act (and which continues to be effective at the time of such
transfer) or sold pursuant to Rule 144 or any similar provision then in force, or unless otherwise
agreed by the Company in writing, with written notice thereof to the Trustee.

Every Security (and all securities issued in exchange therefor or in substitution thereof)
that bears or is required under this Section 2.10 to bear the legend required by this Section 2.10
(together with any Common Stock issued upon conversion of the Securities and required to bear the
legend set forth in Exhibit B, collectively, the “Restricted Securities”) shall be subject to the
restrictions on transfer set forth in this Section 2.10 and such legends, unless such restrictions
on transfer shall be waived by written consent of the Company following receipt of legal advice
supporting the permissibility of the waiver of such transfer restrictions, and the Holder of any
Restricted Securities, by such Holder’s acceptance thereof, agrees to be bound by all such
restrictions on transfer. As used in this Section 2.10, the term “transfer” means any sale,
pledge, loan, transfer or other disposition whatsoever of any Restricted Security or any interest
therein.

In connection with any transfer of the Securities that are Restricted Securities prior to the
date one year after the last date of original issuance of the Securities (other than a transfer
pursuant to a registration statement which has been declared effective under the Securities Act),
the Holder must complete and deliver the form of assignment set forth on the certificate
representing the Securities with the appropriate box checked to the Trustee (or any successor
Trustee, as applicable). If the proposed
transfer is pursuant to clause (2)(D) of the Restricted Security Legend, the Holder must,
prior to such transfer, furnish to the Trustee (or any successor Trustee, as applicable), such
certifications, legal opinions or other information as the Company may reasonably require to
confirm that such transfer is being made pursuant to an exemption from, or in a transaction not
subject to, the registration requirements of the Securities Act. The Restricted Security Legend
will be removed upon the earlier of (1) the first anniversary of the Issue Date, (2) the transfer
of the Security evidenced thereby pursuant to clause (2)(B) of the Restricted Security Legend or
(3) on any transfer of the Security under Rule 144.

 

23

 

Any Securities that are Restricted Securities and as to which such restrictions on transfer
shall have expired in accordance with their terms or as to conditions for removal of the Restricted
Security Legend set forth therein have been satisfied may, upon surrender of such Securities for
exchange to the Security Registrar in accordance with the provisions of this Section 2.10, be
exchanged for a new Security or Securities, of like tenor and aggregate principal amount, which
shall not bear the Restricted Security Legend required by this Section 2.10. If such Restricted
Security surrendered for exchange is represented by a Global Security bearing the Restricted
Security Legend, the principal amount of the legended Global Securities shall be reduced by the
appropriate principal amount and the principal amount of a Global Security without the Restricted
Security Legend shall be increased by an equal principal amount. If a Global Security without the
Restricted Security Legend is not then outstanding, the Company shall execute and the Trustee shall
authenticate and deliver an unlegended Global Security to the Depositary.

Section 2.11. Responsibilities And Obligations of The Trustee. The Trustee shall have no
responsibility or obligation to any Agent Members or any other Person with respect to the accuracy
of the books or records, or the acts or omissions, of the Depositary or its nominee or of any
participant or member thereof, with respect to any ownership interest in the Securities or with
respect to the delivery to any Agent Member or other Person (other than the Depositary) of any
notice or the payment of any amount, under or with respect to such Securities. All notices and
communications to be given to the Holders of Securities and all payments to be made to Holders of
Securities under the Securities shall be given or made only to or upon the order of the registered
Holders of Securities (which shall be the Depositary or its nominee in the case of a Global
Security). The rights of beneficial owners in any Global Securities shall be exercised only
through the Depositary subject to the customary procedures of the Depositary. The Trustee may rely
and shall be fully protected in relying upon information furnished by the Depositary with respect
to its Agent Members.

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 Securities (including any transfers between or among Agent
Members) 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.

 

24

 

Section 2.12. Replacement Securities. If a mutilated Security is surrendered to the
Security Registrar or if the Securityholder of a Security claims that the Security has been lost,
destroyed or wrongfully taken, the Company shall issue and the Trustee shall authenticate a
replacement Security if the requirements of Section 8-405 of the Uniform Commercial Code are met,
such that the Securityholder (i) notifies the Company or the Trustee within a reasonable time after
he has notice of such loss, destruction or wrongful taking and the Security Registrar does not
register a transfer prior to receiving such notification, (ii) makes such request to the Company or
the Trustee prior to the Security being acquired by a protected purchaser as defined in Section
8-303 of the Uniform Commercial Code (a “protected purchaser”) and (iii) satisfies any other
reasonable requirements of the Trustee and the Company. If required by the Trustee or the Company,
such Securityholder shall furnish an indemnity bond sufficient in the judgment of the Trustee to
protect the Company, the Trustee, the Paying Agent, the Conversion Agent and the Security Registrar
from any loss that any of them may suffer if a Security is replaced. The Company and the Trustee
may charge the Securityholder for their expenses in replacing a Security. In case any Security
which has matured or is about to mature or has been properly tendered for repurchase on a
Fundamental Change Repurchase Date (and not withdrawn) or is to be converted into Common Stock,
shall become mutilated or be destroyed, lost or stolen, the Company may, instead of issuing a
substitute Security, pay or authorize the payment of or convert or authorize the conversion of the
same (without surrender thereof except in the case of a mutilated Securities), as the case may be,
if the applicant for such payment or conversion shall furnish to the Company, to the Trustee and,
if applicable, to such authenticating agent such security or indemnity as may be required by them
to save each of them harmless for any loss, liability, cost or expense caused by or in connection
with such substitution, and, in every case of destruction, loss or theft, the applicant shall also
furnish to the Company, the Trustee and, if applicable, any Paying Agent or Conversion Agent
evidence to their satisfaction of the destruction, loss or theft of such Securities and of the
ownership thereof.

Every replacement Security is an additional obligation of the Company.

The provisions of this Section 2.12 are exclusive and shall preclude (to the extent lawful)
all other rights and remedies with respect to the replacement or payment of mutilated, lost,
destroyed or wrongfully taken Securities.

Section 2.13. Outstanding Securities. Securities outstanding at any time are all Securities
authenticated by the Trustee except for those canceled by it, those delivered to it for
cancellation and those described in this Section 2.13 as not outstanding. A Security does not
cease to be outstanding because the Company or an Affiliate of the Company holds the Security.

 

25

 

If a Security is replaced pursuant to Section 2.12, it ceases to be outstanding unless the
Trustee and the Company receive proof satisfactory to them that the replaced Security is held by a
protected purchaser.

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

Section 2.14. Temporary Securities. Pending the preparation of Securities in certificated
form, the Company may execute and the Trustee or an authenticating agent appointed by the Trustee
shall, upon the written request of the Company, authenticate and deliver temporary Securities
(printed or lithographed). Temporary Securities shall be issuable in any authorized denomination,
and substantially in the form of the Securities in certificated form, but with such omissions,
insertions and variations as may be appropriate for temporary Security, all as may be determined by
the Company. Every such temporary Securities shall be executed by the Company and authenticated by
the Trustee or such authenticating agent upon the same conditions and in substantially the same
manner, and with the same effect, as the Securities in certificated form. Without unreasonable
delay, the Company will execute and deliver to the Trustee or such authenticating agent Securities
in certificated form and thereupon any or all temporary Securities may be surrendered in exchange
therefor, at each office or agency maintained by the Company pursuant to Section 3.02 and the
Trustee or such authenticating agent shall authenticate and make available for delivery in exchange
for such temporary Securities an equal aggregate principal amount of Securities in certificated
form. Such exchange shall be made by the Company at its own expense and without any charge
therefor. Until so exchanged, the temporary Securities shall in all respects be entitled to the
same benefits and subject to the same limitations under this Indenture as Securities in
certificated form authenticated and delivered hereunder.

Section 2.15. Cancellation. The Company at any time may deliver Securities to the Trustee
for cancellation. The Security Registrar and the Paying Agent shall forward to the Trustee any
Securities surrendered to them for registration of transfer, exchange or payment. The Trustee and
no one else shall cancel all Securities surrendered for registration of transfer, exchange, payment
or cancellation and deliver canceled Securities to the Company pursuant to written direction by an
Officer. The Company may not issue new Securities to replace Securities it has redeemed, paid or
delivered to the Trustee for cancellation. The Trustee shall not authenticate Securities in place
of canceled Securities other than pursuant to the terms of this Indenture.

 

26

 

Section 2.16. CUSIP and ISIN Numbers. The Company in issuing the Securities may use “CUSIP”
and “ISIN” numbers (if then generally in use) and, if so, the Trustee shall use “CUSIP” and “ISIN”
numbers in notices of redemption as a convenience to Securityholders; provided that any such notice
may state that no representation is made as to the correctness of such numbers either as printed on
the Securities or as contained in any notice of a redemption and that reliance may be placed only
on the other identification numbers printed on the Securities, and any such redemption shall not be
affected by any defect in or omission of such numbers.

Section 2.17. Additional Securities. The Company may, from time to time without the consent
of the Holders of outstanding Securities, increase the principal amount of the Securities by
issuing additional Securities in the future pursuant to this Indenture (“Additional Securities”)
having terms and conditions identical to those of the other outstanding Securities, except that
Additional Securities may have a different initial date from which interest begins to accrue
thereon so that the Additional Securities are fungible with outstanding Securities; provided that
no differences pursuant to this Section 2.17 shall cause such Additional Securities to constitute a
different class of securities than the Securities issued pursuant to the Purchase Agreement for
U.S. federal income tax purposes; and provided further, that the Additional Securities shall have
the same CUSIP number as the Securities issued pursuant to the Purchase Agreement. The Securities
originally issued pursuant to the Purchase Agreement and any Additional Securities shall be treated
as a single class for all purposes under this Indenture, including waivers, amendments, offers to
purchase and United States federal tax purposes. No Additional Securities may be issued if on the
Issue Date therefor any Event of Default has occurred and is continuing.

ARTICLE 3

Particular Covenants of the Company

Section 3.01. Payment of Principal and Interest. The Company covenants and agrees that it
shall duly and punctually pay or cause to be paid the principal of, and interest on, each of the
Securities at the places, at the respective times and in the manner provided herein and in the
Securities.

Section 3.02. Maintenance of Office or Agency. The Company shall maintain an office or
agency in the Borough of Manhattan, the City of New York, where the Securities may be surrendered

where notices and demands to or upon the Company in respect of the Securities and this Indenture
may be served. The Company shall give prompt written notice to the Trustee of the location, and
any change in the location, of such office or agency not designated or appointed by the Trustee.
If at any time the Company shall fail to maintain any such required office or agency or shall fail
to furnish the Trustee with the address thereof, such presentations, surrenders, notices and
demands may be made or served at the Corporate Trust
Office, and the Company hereby appoints the Trustee as its agent to receive all such
presentations, surrenders, notices and demands.

 

27

 

The Company may also from time to time designate co-registrars and one or more offices or
agencies where the Securities may be presented or surrendered for any or all such purposes and may
from time to time rescind such designations.

The Company will give prompt written notice of any such designation or rescission and of any
change in the location of any such other office or agency.

The Company hereby initially designates the Trustee as paying agent, Security Registrar,
Custodian and conversion agent at the Corporate Trust Office.

So long as the Trustee is the Security Registrar, the Trustee agrees to mail, or cause to be
mailed, the notices set forth in Section 8.11(a) and the third paragraph of Section 8.12. If
co-registrars have been appointed in accordance with this Section, the Trustee shall mail such
notices only to the Company and the Holders of Securities it can identify from its records.

Section 3.03. Provisions as to Paying Agent.

(a) If the Company shall appoint a Paying Agent other than the Trustee, or if the Trustee
shall appoint such a Paying Agent, the Company will cause such Paying Agent to execute and deliver
to the Trustee an instrument in which such agent shall agree with the Trustee, subject to the
provisions of this Section 3.03:

(i) that it will hold all sums held by it as such agent for the payment of the
principal of or interest, on the Securities (whether such sums have been paid to it by the
Company or by any other obligor on the Securities) in trust for the benefit of the Holders
of the Securities;

(ii) that it will give the Trustee notice of any failure by the Company (or by any
other obligor on the Securities) to make any payment of the principal of or interest on
the Securities when the same shall be due and payable; and

(iii) that at any time during the continuance of an Event of Default, upon request of
the Trustee, it will forthwith pay to the Trustee all sums so held in trust.

The Company shall, on or before each due date of the principal of or interest on the
Securities, deposit with the paying agent a sum (in funds which are immediately available on the
due date for such payment) sufficient to pay such principal or interest, and (unless such paying
agent is the Trustee) the Company will promptly notify the Trustee of any failure to take such
action; provided, however, that if such deposit is made on the due date, such deposit shall be
received by the paying agent by 11:00 a.m. New York City time, on such date.

 

28

 

(b) If the Company shall act as its own Paying Agent, it will, on or before each due date of
the principal of or interest on the Securities, set aside, segregate and hold in trust for the
benefit of the Holders of the Securities a sum sufficient to pay such principal or interest so
becoming due and will promptly notify the Trustee of any failure to take such action and of any
failure by the Company (or any other obligor under the Securities) to make any payment of the
principal of or interest on the Securities when the same shall become due and payable.

(c) Anything in this Section 3.03 to the contrary notwithstanding, the Company may, at any
time, for the purpose of obtaining a satisfaction and discharge of this Indenture, or for any other
reason, pay or cause to be paid to the Trustee all sums held in trust by the Company or any paying
agent hereunder as required by this Section 3.03, such sums to be held by the Trustee upon the
trusts herein contained and upon such payment by the Company or any paying agent to the Trustee,
the Company or such paying agent shall be released from all further liability with respect to such
sums.

(d) Anything in this Section 3.03 to the contrary notwithstanding, the agreement to hold sums
in trust as provided in this Section 3.03 is subject to Section 10.03 and Section 10.04.

The Trustee shall not be responsible for the actions of any other paying agents (including the
Company if acting as its own paying agent) and shall have no control of or liability for any funds
held by such other paying agents.

Section 3.04. Rule 144A Information Requirement. Until the first anniversary of the Issue
Date, 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, make available to any Holder or beneficial holder of
Securities or any Common Stock issued upon conversion thereof which continue to be 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 upon the request of any Holder or beneficial holder of the
Securities or such Common Stock, 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.

Section 3.05. Resale of Certain Securities. The Company shall not, and shall not permit any
of its “affiliates” (as defined under Rule 144 or any successor provision thereto) to, resell any
Securities that have been reacquired by any of them. The Trustee shall have no responsibility in
respect of the Company’s performance of its agreement in the preceding sentence.

 

29

 

Section 3.06. Commission Filings. The Company will deliver to the Trustee within 15 days
after it is required to file the same with the Commission, copies of the
quarterly and annual reports and of the information, documents and other reports, if any,
which the Company is required to file, and only to the extent it is required to file, with the
Commission pursuant to Section 13 or 15(d) of the Exchange Act, and shall otherwise comply with the
requirements of § 314(a)(1) of the Trust Indenture Act. To the extent any such information,
documents and reports are filed by the Company electronically on the Commission’s Electronic Data
Gathering and Retrieval System (or any successor system), notice thereof shall be delivered
promptly to the Trustee, upon which such information, documents and reports shall be deemed
delivered to the Trustee.

Section 3.07. Book-Entry System. If the Securities cease to trade in the Depositary’s
book-entry settlement system, the Company covenants and agrees that it shall use reasonable efforts
to make such other book entry arrangements that it determines are reasonable for the Securities.

Section 3.08. Additional Interest under the Registration Rights Agreement. If at any time
Additional Interest become payable by the Company pursuant to the Registration Rights Agreement,
the Company shall promptly deliver to the Trustee a certificate to that effect and stating (i) the
amount of such Additional Interest that is payable and (ii) the date on which such Additional
Interest is payable pursuant to the terms of the Registration Rights Agreement. Unless and until a
Responsible Officer of the Trustee receives such a certificate, the Trustee may assume without
inquiry that no Additional Interest is payable. If the Company has paid Additional Interest
directly to the Persons entitled to such Additional Interest, the Company shall deliver to the
Trustee a certificate setting forth the particulars of such payment.

Section 3.09. Compliance Certificate. The Company shall deliver to the Trustee, within 120
days after the end of each fiscal year of the Company, an Officers’ Certificate, stating whether or
not to the knowledge of the signer thereof the Company is in default in the performance and
observance of any of the terms, provisions, covenants and conditions of this Indenture (without
regard to any period of grace or requirement of notice provided hereunder) or has been in default
during the previous year and, if the Company shall be in default, or shall have been in default
during the previous year, specifying all such defaults and the nature and the status thereof of
which the signer may have knowledge.

setting forth the details of such Event of Default or Default, its status and the action which the
Company proposes to take with respect thereto.

Any notice required to be given under this Section 3.09 shall be delivered to a Responsible
Officer of the Trustee at its Corporate Trust Office.

Fundamental Changes and Purchases Thereupon

Section 4.01. Repurchase at Option of Holders Upon a Fundamental Change.

(a) Generally. If a Fundamental Change occurs at any time prior to the Maturity of the
Securities, then each Securityholder shall have the right, at such Holder’s option, to require the
Company to purchase for cash any or all of such Holder’s Securities, or any portion of the
principal amount thereof, that is a multiple of $1,000 principal amount, on a date specified by the
Company that is no earlier than the 20th calendar day following the date of, and no later than the
45th calendar day following the date of the Fundamental Change Company Notice (as defined below)
(the “Fundamental Change Repurchase Date”), at a purchase price equal to 100% of the principal
amount thereof, together with accrued and unpaid interest thereon to, but excluding, the
Fundamental Change Repurchase Date (the “Fundamental Change Repurchase Price”); provided, however,
that if a Fundamental Change Repurchase Date is after a Record Date and on or prior to the Interest
Payment Date related thereto, the interest, payable in respect of such Interest Payment Date shall
be payable to the Holders of record as of the corresponding Record Date and the Fundamental Change
Repurchase Price shall be equal to 100% of the principal amount of Securities to be purchased
pursuant to this Article 4.

Purchases of Securities under this Section 4.01 shall be made, at the option of the Holder
thereof, upon:

(i) delivery to the Trustee (or other Paying Agent appointed by the Company) by a
Holder, prior to the close of business on the Business Day immediately preceding the
Fundamental Change Repurchase Date, subject to extension to comply with applicable law, of
a duly completed notice (the “Fundamental Change Repurchase Notice”) in the form set forth
on the reverse of the Securities specifying:

(A) if Physical Securities have been issued, the certificate numbers of
such Securities to be delivered for purchase;

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

(C) that the Securities are to be purchased by the Company pursuant to the
applicable provisions of the Securities and the Indenture; and

 

31

 

(ii) delivery or book-entry transfer of the Securities to the Trustee (or other
Paying Agent appointed by the Company) (together with all necessary endorsements) at any
time prior to the close of business on the Business Day immediately preceding the
Fundamental Change Repurchase Date, subject to extension to comply with applicable law, at
the applicable Corporate Trust Office of the Trustee (or other Paying Agent appointed by
the Company), such delivery being a condition to receipt by the Holder of the Fundamental
Change Repurchase Price therefor; provided that (x) such Fundamental Change Repurchase
Price shall be so paid pursuant to this Section 4.01 only if the Securities so delivered
to the Trustee (or other Paying Agent appointed by the Company) shall conform in all
respects to the description thereof in the related Fundamental Change Repurchase Notice
and (y) if Physical Securities have not been issued, the Fundamental Change Repurchase
Notice must comply with appropriate procedures of the Depositary.

Any purchase by the Company contemplated pursuant to the provisions of this Section 4.01 shall
be consummated by the delivery of the consideration to be received by the Holder promptly following
the later of the Fundamental Change Repurchase Date and the time of the book-entry transfer or
delivery of the Securities (as specified in Section 4.02 hereof).

Notwithstanding anything herein to the contrary, any Holder delivering to the Trustee (or
other Paying Agent appointed by the Company) the Fundamental Change Repurchase Notice contemplated
by this Section 4.01 shall have the right to withdraw such Fundamental Change Repurchase Notice at
any time prior to the close of business on the Business Day immediate preceding the Fundamental
Change Repurchase Date by delivery of a written notice of withdrawal to the Trustee (or other
Paying Agent appointed by the Company) in accordance with Section 4.03 below.

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

(b) Fundamental Change Company Notice. On or before the 20th calendar day after the
occurrence of a Fundamental Change, the Company shall provide to all Holders of record of the
Securities and the Trustee and Paying Agent (in the case of a Paying Agent other than the Trustee)
a notice (the “Fundamental Change Company Notice”) of the occurrence of such Fundamental Change and
of the purchase right at the option of the Holders arising as a result thereof. Such mailing shall
be by first class mail or in the case of Global Securities, in accordance with the procedures of
the Depositary for providing notices. Simultaneously with providing such Fundamental Change
Company Notice, the Company shall publish a notice
containing the information included therein on the Company’s website or through such other
public medium as the Company may use at such time.

 

32

 

Each Fundamental Change Company Notice shall specify:

(i) the events causing a Fundamental Change;

(ii) the date of the Fundamental Change;

(iii) the last date on which a Securityholder may exercise the repurchase right
pursuant to this Article 4;

(iv) the Fundamental Change Repurchase Price;

(v) the Fundamental Change Repurchase Date;

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

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

(viii) if applicable, that the Securities with respect to which a Fundamental Change
Repurchase Notice has been delivered by a Holder may be converted only if the Holder
withdraws the Fundamental Change Repurchase Notice in accordance with Section 4.03; and

(ix) the procedures that Holders must follow to require the Company to purchase their
Securities.

No failure of the Company to give the foregoing notices and no defect therein shall limit the
Securityholders’ purchase rights or affect the validity of the proceedings for the purchase of the
Securities pursuant to this Section 4.01.

(c) No Payment During Events of Default. There shall be no purchase of any Securities
pursuant to this Section 4.01 if there has occurred and is continuing an Event of Default (other
than an Event of Default that is cured by the payment of the Fundamental Change Repurchase Price of
the Securities). The Paying Agent will promptly return to the respective Holders thereof any
Securities (i) with respect to which a Fundamental Change Repurchase Notice has been withdrawn in
compliance with this Indenture, or (ii) held by it during the continuance of an Event of Default
(other than an Event of Default that is cured by the payment of the Fundamental Change Repurchase
Price with respect to such Securities) in which case, upon such return, the Fundamental Change
Repurchase Notice with respect thereto shall be deemed to have been withdrawn.

 

33

 

Section 4.02. Effect of Fundamental Change Repurchase Notice. Upon receipt by the Paying
Agent of the Fundamental Change Repurchase Notice specified in Section 4.01(a), 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 in accordance with Section 4.03) thereafter be
entitled to receive solely the Fundamental Change Repurchase Price in cash with respect to such
Security. Such Fundamental Change Repurchase Price shall be paid to such Holder, subject to receipt
of funds by the Paying Agent, promptly following the later of (x) the Fundamental Change Repurchase
Date with respect to such Security (provided the conditions in Section 4.01(a) have been satisfied)
and (y) the time of delivery of such Security to the Paying Agent by the Holder thereof in the
manner required by Section 4.01(a)(ii).

Section 4.03. Withdrawal of Fundamental Change Repurchase Notice. A Fundamental Change
Repurchase Notice may be withdrawn by means of a written notice of withdrawal delivered to the
Paying Agent in accordance with the Fundamental Change Company Notice at any time prior to the
close of business on the Business Day immediately preceding the Fundamental Change Repurchase Date,
specifying:

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

(ii) if Physical Securities have been issued, the certificate numbers of the
withdrawn Securities; and

(iii) the principal amount of such Securities that remains subject to the original
Fundamental Change Repurchase Notice, which portion must be in principal amounts of $1,000
or a multiple of $1,000;

provided, however, that if Physical Securities have not been issued, the notice must comply with
appropriate procedures of the Depositary.

Section 4.04. Deposit of Fundamental Change Repurchase Price. Prior to 10:00 a.m. (local
time in The City of New York) on a date that is promptly following the later of the Fundamental
Change Repurchase Date and the time of the book-entry transfer or delivery of the Securities in
accordance with this Article 4, subject to extension to comply with applicable law, the Company
shall deposit with the Trustee or with the Paying Agent (or, if the Company or a Subsidiary or an
Affiliate of either of them is acting as the Paying Agent, shall segregate and hold in trust as
provided herein) an amount of money (in immediately available funds if deposited on such Business
Day) sufficient to pay the Fundamental Change Repurchase Price, of all the Securities or portions
thereof that are to be purchased as of the Fundamental Change Repurchase Date. The Company shall
promptly notify the Trustee in writing of the amount of any deposits of cash made pursuant to this
Section 4.04.

 

34

 

If the Paying Agent holds cash sufficient to pay the Fundamental Change Repurchase
Price of any Security for which a Fundamental Change Repurchase Notice has been tendered and
not withdrawn in accordance with this Indenture as of the close of business on the Business
Day following the Fundamental Change Repurchase Date, then as of such Business Day following the
Fundamental Change Repurchase Date, (a) such Security will cease to be outstanding and interest
will cease to accrue thereon (whether or not book-entry transfer of such Security is made or such
Security is delivered to the Paying Agent) and (b) all other rights of the Holder in respect
thereof will terminate (other than the right to receive the Fundamental Change Repurchase Price and
previously accrued and unpaid interest upon delivery or book-entry transfer of such Security).

Section 4.05. Securities Repurchased in Whole or in Part. Any Security that is to be
repurchased, whether in whole or 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 service charge, a new
Security or Securities, of any authorized denomination as requested by such Holder in aggregate
principal amount equal to, and in exchange for, the portion of the principal amount of the Security
so surrendered that is not purchased.

Section 4.06. Covenant to Comply With Securities Laws Upon Purchase of Securities. In
connection with any offer to purchase Securities under Section 4.01, the Company, if required,
shall (i) comply with Rule 13e-4 and Rule 14e-1 under the Exchange Act, (ii) file the related
Schedule TO (or any successor schedule, form or report) under the Exchange Act, and (iii) otherwise
comply with all Federal and state securities laws so as to permit the rights and obligations under
Section 4.01 to be exercised in the time and in the manner specified in Section 4.01.

Section 4.07. Repayment to the Company. The Trustee and the Paying Agent shall return to
the Company any cash that remains unclaimed, together with interest, or dividends, if any, thereon,
held by them for the payment of the Fundamental Change Repurchase Price; provided that to the
extent that the aggregate amount of cash deposited by the Company pursuant to Section 4.04 exceeds
the aggregate Fundamental Change Repurchase Price of the Securities or portions thereof that the
Company is obligated to purchase as of the Fundamental Change Repurchase Date, then as soon as
practicable following the Fundamental Change Repurchase Date, the Trustee or the Paying Agent, as
the case may be, shall return any such excess to the Company.

ARTICLE 5

Conversion

Section 5.01. Right to Convert.

(a) Subject to and upon compliance with the provisions of this Indenture, each Holder shall
have the right, at such Holder’s option, to convert the principal amount of any such Securities, or
any portion of such principal amount which is $1,000 or an integral multiple of $1,000 thereof at
the Conversion Rate then in effect, (x) on or after November 1, 2012 through the close of business
on the Business Day immediately preceding Stated Maturity and (y) prior to November 1, 2012, but
only upon the satisfaction of one or more of the conditions set forth in clauses (i) through (v)
below and only during the periods set forth below:

(i) Prior to the close of business on the Business Day immediately preceding November
1, 2012, a Holder may surrender all or a portion of its Securities for conversion during
any fiscal quarter (and only during such fiscal quarter) commencing after March 31, 2008,
if the Last Reported Sale Price for the Common Stock for at least 20 Trading Days during
the period of 30 consecutive Trading Days ending on the last Trading Day of the
immediately preceding fiscal quarter is greater than or equal to 130% of the Applicable
Conversion Price in effect on each such Trading Day.

(ii) Prior to the close of business on the Business Day immediately preceding
November 1, 2012, a Holder may surrender its Securities for conversion during the five
Business-Day period after any five consecutive Trading-Day period (the “Measurement
Period”) in which the Trading Price per $1,000 principal amount of Securities, as
determined following a request by a Holder in accordance with the procedures set forth in
this Section 5.01(a)(ii), for each day of such five consecutive Trading-Day period was
less than 98% of the product of the Last Reported Sale Price of the Common Stock and the
Applicable Conversion Rate. The Bid Solicitation Agent shall have no obligation to
determine the Trading Price of the Securities in accordance with this Section 5.01(a)(ii)
unless requested by the Company, and the Company shall have no obligation to make such
request unless a Holder provides the Company with reasonable evidence that the Trading
Price per $1,000 principal amount of Securities would be less than 98% of the product of
the Last Reported Sale Price of the Common Stock and the Applicable Conversion Rate.
Promptly after receiving such evidence, the Company shall instruct the Bid Solicitation
Agent to determine the Trading Price of the Securities beginning on the next Trading Day
and on each successive Trading Day until the Trading Price per $1,000 principal amount of
Securities is greater than or equal to 98% of the product of the Last Reported Sale Price
of the Common Stock and the Applicable Conversion Rate.

 

36

 

If the Company does not so
instruct the Bid Solicitation Agent to obtain bids when required, the Trading Price per
$1,000 principal amount of Securities will be deemed to be less than 98% of the product of
the Last
Reported Sale Price of the Common Stock and the Applicable Conversion Rate on each
day the Company fails to do so. If the Trading Price condition has been met the Company
shall notify the Holders of the Securities in the manner provided in Section 1.06, the
Trustee and the Conversion Agent. If, at any time after the Trading Price condition has
been met, the Trading Price per $1,000 principal amount of Securities is greater than or
equal to 98% of the product of the Last Reported Sale Price of the Common Stock and the
Applicable Conversion Rate the Company shall so notify the Holders of the Securities in
the manner provided in Section 1.06, the Trustee and the Conversion Agent.

(iii) If, prior to the close of business on the Business Day immediately preceding
November 1, 2012, the Company elects to:

(A) issue to all or substantially all holders of Common Stock certain
rights (in the case of rights issued under a shareholder rights agreement, only
following the distribution of separate certificates evidencing such rights)
entitling them to purchase, for a period expiring within 60 days after the date
of the distribution, shares of Common Stock at less than the average of the Last
Reported Sale Prices of a share of Common Stock for the 10 consecutive
Trading-Day period ending on the Trading Day immediately preceding the
announcement of such issuance; or

(B) distribute to all or substantially all holders of Common Stock assets,
debt securities or certain rights to purchase securities of the Company, which
distribution has a per share Fair Market Value, as reasonably determined by the
Company’s Board of Directors, exceeding 10% of the Last Reported Sale Price of
the Common Stock on the Trading Day preceding the declaration date for such
distribution,

then, in each case, the Company shall notify the Holders of the Securities, in the manner
provided in Section 1.06, at least 30 Scheduled Trading Days prior to the Ex-Dividend Date
for such distribution. Once the Company has given such notice, Holders may surrender
Securities for conversion at any time until the earlier of 5:00 p.m., New York City time,
on the Business Day immediately prior to such Ex-Dividend Date or the Company’s
announcement that such distribution will not take place, even if the Securities are not
otherwise convertible at such time.

 

37

 

(iv) If, prior to the close of business on the Business Day immediately preceding
November 1, 2012, a transaction or event that constitutes a Fundamental Change or a
Make-Whole Fundamental Change occurs, regardless of whether a Holder has the right to
require the Company to repurchase the Securities pursuant to Article 4 hereof, or if the
Company is a party to a consolidation, merger, binding share exchange, or transfer or
lease of all or substantially all of the Company’s assets, pursuant to which the
Common Stock would be converted into cash, securities or other assets, Holders may
surrender Securities for conversion at any time from or after the effective date of such
transaction until 35 Trading Days after the effective date of such transaction or, if such
transaction also constitutes a Fundamental Change, until the close of business on the
Business Day immediately preceding the related Fundamental Change Repurchase Date. The
Company shall notify Holders and the Trustee, in the manner provided in Section 1.06, as
promptly as practicable following the date the Company publicly announces such
transaction, but in any event, within five Scheduled Trading Days after the effective date
of such transaction.

(v) Prior to the close of business on the Business Day immediately preceding November
1, 2012, Holders may surrender Securities for conversion at any time beginning on the
first Business Day after the Common Stock ceases to be listed on a United States national
or regional securities exchange.

(b) Securities may not be converted after the close of business on the Business Day
immediately preceding February 1, 2013.

Section 5.02. Conversion Procedure.

(a) Each Security shall be convertible at the office of the Conversion Agent.

(b) In order to exercise the conversion privilege with respect to any interest in a Global
Security, the Holder must complete the appropriate instruction form for conversion pursuant to the
Depositary’s book-entry conversion program, furnish appropriate endorsements and transfer documents
if required by the Company or the Trustee or Conversion Agent, and pay the funds, if any, required
by Section 5.03(e) and any transfer taxes, if required, pursuant to Section 5.08, and the Trustee
or Conversion Agent must be informed of the conversion in accordance with customary practice of the
Depositary. In order to exercise the conversion privilege with respect to any Physical Securities,
the Holder of any such Securities to be converted, in whole or in part, shall:

(i) complete and manually sign the conversion notice provided on the back of the
Security (the “Conversion Notice”) or facsimile of the Conversion Notice and deliver such
notice, which is irrevocable, to the Conversion Agent;

(ii) surrender the Security to the Conversion Agent;

(iii) if required, furnish appropriate endorsements and transfer documents,

 

38

 

(iv) if required, pay all transfer or similar taxes; and

(v) make any payment required under Section 5.03(e).

The date on which the Holder satisfies all of the applicable requirements set forth above is
the “Conversion Date.” The Trustee will, as promptly as possible, and in any event within two (2)
Business Days, provide the Company with notice of any conversion exercises by Holders of which a
Responsible Officer becomes aware.

(c) Each Conversion Notice shall state the name or names (with address or addresses) in which
any certificate or certificates for shares of Common Stock which shall be issuable on such
conversion shall be issued. All such Securities surrendered for conversion shall, unless the
shares issuable on conversion are to be issued in the same name as the registration of such
Securities, be duly endorsed by, or be accompanied by instruments of transfer in form satisfactory
to the Company duly executed by, the Holder or his duly authorized attorney.

(d) In case any Securities of a denomination greater than $1,000 shall be surrendered for
partial conversion, the Company shall execute and the Trustee shall authenticate and deliver to the
Holder of the Securities so surrendered, without charge to such Holder, new Securities in
authorized denominations in an aggregate principal amount equal to the unconverted portion of the
surrendered Securities.

Each conversion shall be deemed to have been effected as to any such Securities (or portion
thereof) surrendered for conversion on the relevant Conversion Date, and the person in whose name
any certificate or certificates for shares of Common Stock shall be issuable upon such conversion
in respect of each Trading Day during an Observation Period, if applicable, shall become the holder
of record of such shares of Common Stock as of the close of business on the last Trading Day of
such Observation Period; provided, however, that if such last Trading Day is a date when the stock
transfer books of the Company shall be closed, the person or persons in whose name the certificate
or certificates for such shares are to be issued shall be deemed to have become the Holder of
record thereof for all purposes on the next day on which such stock transfer books are open.

(e) Upon the conversion of an interest in Global Securities, the Trustee (or other Conversion
Agent appointed by the Company) shall make a notation on such Global Securities as to the reduction
in the principal amount represented thereby. The Company shall notify the Trustee in writing of any
conversions of Securities effected through any Conversion Agent other than the Trustee.

(f) Notwithstanding the foregoing, a Security in respect of which a Holder has delivered a
Fundamental Change Repurchase Notice exercising such Holder’s option to require the Company to
purchase such Security may be converted only if such notice of exercise is withdrawn in accordance
with Article 4 hereof prior to the close of business on the Business Day prior to the relevant
Fundamental Change Repurchase Date.

 

39

 

Section 5.03. Payments Upon Conversion.

(a) Upon any conversion of any Security, on the third Business Day immediately following the
last Trading Day of the relevant Observation Period, the Company shall pay or deliver, as the case
may be, to converting Holders, in respect of each $1,000 principal amount of Securities being
converted, a “Settlement Amount” equal to the sum of the Daily Settlement Amounts for each of the
60 Trading Days during the applicable Observation Period for such Security.

“Observation Period” means (i) with respect to any Security converted prior to November 1,
2012, the 60 consecutive Trading-Day period beginning on and including the second Trading Day after
the related Conversion Date and (ii) with respect to any Security converted on or after November 1,
2012, the 60 consecutive Trading Days beginning on, and including, the 62nd Scheduled Trading Day
immediately preceding February 1, 2013.

(b) The “Daily Settlement Amount” for each of the 60 Trading Days during the Observation
Period shall consist of:

(i) cash equal to the lesser of (x) one-sixtieth of $1,000 and (y) the Daily
Conversion Value, and

(ii) to the extent the Daily Conversion Value exceeds one-sixtieth of $1,000, a
number of shares of Common Stock (the “Daily Share Amount”) equal to (x) the difference
between the Daily Conversion Value and one-sixtieth of $1,000, divided by (y) the Daily
VWAP for such day subject to the Company’s right to deliver a percentage of the Daily
Share Amount in cash in accordance with Section 5.03(c).

provided, that to the extent the aggregate number of shares of Common Stock the Company would
otherwise be required to deliver pursuant to the foregoing calculation as a part of the Settlement
Amount, when taken together with shares of Common Stock delivered upon previous conversions, if
any, exceeds the “Aggregate Share Cap” (the maximum number of shares of Common Stock that the
Company may issue without shareholder approval pursuant to NASDAQ listing requirements, subject to
adjustment upon the occurrence of any of the events described in Section 5.04(a)), then the Company
will not deliver such excess number of shares of Common Stock unless, in accordance with NASDAQ
listing requirements, the Company has obtained the approval of its shareholders for the issuance of
shares of Common Stock in excess of the Aggregate Share Cap.

“Daily Conversion Value” means, for each of the 60 consecutive Trading Days during the
Observation Period, one-sixtieth of the product of (i) the Applicable Conversion Rate and (ii) the
Daily VWAP of Common Stock on such Trading Day.

 

40

 

“Daily VWAP” means, for each of the 60 consecutive Trading Days during the Observation Period,
the per share volume-weighted average price as displayed
under the heading “Bloomberg VWAP” on Bloomberg page “GMXR <equity> AQR” (or its
equivalent successor if such page is not available) in respect of the period from the scheduled
open of trading until the scheduled close of trading of the primary trading session on such Trading
Day (or if such volume-weighted average price is unavailable, the market value of one share of
Common Stock on such Trading Day determined, using a volume-weighted average method, by a
nationally recognized independent investment banking firm retained for such purpose by the
Company). The Daily VWAP will be determined without regard to after hours trading or any other
trading outside of the regular trading session trading hours.

(c) By the close of business on the Business Day prior to the first Scheduled Trading Day of
the applicable Observation Period, the Company may specify a percentage of the Daily Share Amount
included in the Daily Settlement Amount that will be settled in cash (the “Cash Percentage”) and
will notify the Securityholders of such Cash Percentage through written notice to the Trustee (the
"Cash Percentage Notice”). If the Company elects to specify a Cash Percentage, (i) the amount of
cash that the Company will deliver in respect of the Daily Share Amount for each Trading Day in the
applicable Observation Period will equal the product of: (x) the Cash Percentage, (y) the Daily
Share Amount for such Trading Day (assuming for this purpose the Company has not specified a Cash
Percentage) and (z) the Daily VWAP for such Trading Day and (ii) the number of shares of Common
Stock deliverable in respect of each Trading Day in the applicable Observation Period (in lieu of
the full Daily Share Amount for such Trading Day) will be a percentage of the Daily Share Amount
(assuming the Company has not specified a Cash Percentage) equal to 100% minus the Cash Percentage.

If the Company does not specify a Cash Percentage by the close of business on the Business Day
prior to the first Scheduled Trading Day of the applicable Observation Period, the Company shall
settle 100% of the Daily Share Amount for each Trading Day in the applicable Observation Period
with shares of Common Stock; provided that the Company shall pay cash in lieu of fractional shares
otherwise issuable upon conversion of such Securities.

(d) Subject to clause (e) below, upon conversion, Holders shall not receive any separate cash
payment for accrued and unpaid interest, unless such conversion occurs between a Record Date and
the Interest Payment Date to which it relates.

(e) If Securities are converted after 5:00 p.m., New York City time, on a Record Date for the
payment of interest, Holders of such Securities at 5:00 p.m., New York City time, on such Record
Date will receive the full amount of interest payable on such Securities on the corresponding
Interest Payment Date notwithstanding the conversion. Securities surrendered for conversion during
the period from 5:00 p.m., New York City time, on any Record Date to 9:00 a.m., New York City time,
on the immediately following Interest Payment Date, must be accompanied by funds equal to the full
amount of interest payable on the Securities so converted; provided that no such payment need be
made (i) if the Company has specified a Fundamental Change Repurchase Date that is after a Record
Date and on or prior to the third Trading Day
after the corresponding Interest Payment Date; (ii) for conversions following the Record Date
immediately preceding February 1, 2013 or (iii) to the extent of any overdue interest, if any
overdue interest exists at the time of conversion with respect to such Security.

 

41

 

(f) The Company shall not issue fractional shares of Common Stock upon conversion of
Securities. If multiple Securities shall be surrendered for conversion at one time by the same
Holder, the number of full shares of Common Stock which shall be issuable upon conversion shall be
computed on the basis of the aggregate principal amount of the Securities (or specified portions
thereof to the extent permitted hereby) so surrendered. If any fractional share of stock would be
issuable upon the conversion of any Securities, the Company shall make payment therefor in cash in
lieu of fractional shares of Common Stock based on the Daily VWAP of the Common Stock on the final
Trading Day of the applicable Observation Period.

(g) Solely for purposes of determining (i) the holder of record in accordance with Section
5.02(d) and (ii) the payments and deliveries due upon conversion under this Section 5.03, and
notwithstanding the definition of “Trading Day” contained in Section 1.01, “Trading Day” means a
day on which (i) there is no Market Disruption Event and (ii) trading in securities generally
occurs on NASDAQ or, if the Common Stock is not then listed on NASDAQ, on the principal other
United States national or regional securities exchange on which the Common Stock is then listed or,
if the Common Stock is not then listed on a United States national or regional securities exchange,
on the principal other market on which the Common Stock is then traded. If the Common Stock (or
other security for which a Daily VWAP must be determined) is not so listed or quoted, “Trading Day”
means a Business Day.

(h) Upon surrender of Securities for conversion in connection with a Make-Whole Fundamental
Change, the Company shall pay and deliver, as the case may be, in lieu of shares of Common Stock,
including the Additional Shares, cash and shares of Common Stock, if any, as described under this
Section 5.03. However, if the consideration paid for the Common Stock in such Make-Whole
Fundamental Change is composed entirely of cash, for any conversion of Securities following the
Effective Date of such Make-Whole Fundamental Change, the Settlement Amount shall be calculated
based solely on the Stock Price for such Make-Whole Fundamental Change (in lieu of the Daily VWAP)
and shall be deemed to be an amount equal to the Applicable Conversion Rate (including any
adjustment as described in Section 5.06 hereof) multiplied by such Stock Price. In such event,
the Settlement Amount shall be determined and paid to Holders solely in cash on the third Business
Day following the relevant Conversion Date.

Section 5.04. Adjustment of Conversion Rate. The Conversion Rate shall be adjusted from
time to time by the Company if any of the following events occurs, except that the Company will not
make any adjustment if Holders of Securities participate, as a result of holding the Securities, at
the same time as Holders of the Common Stock participate, in the transactions described without
having to convert
their Securities as if such Holders held the full number of shares of Common Stock underlying
their Securities.

 

42

 

(a) If the Company, at any time or from time to time while any of the Securities are
Outstanding, issues shares of its Common Stock as a dividend or distribution on shares of Common
Stock, or if the Company effects a share split or share combination, then the Applicable Conversion
Rate will be adjusted based on the following formula:

where

	 	 	 	 	 	 	 
	 

	 	CR0
	 	=
	 	the Conversion Rate in effect immediately prior to the Ex-Dividend Date
of such dividend or distribution, or the effective date of such share split or share
combination, as applicable;
	 
	 	 	 	 	 	 
	 

	 	CR1
	 	=
	 	the Conversion Rate in effect immediately after the opening of business
on such Ex-Dividend Date or effective date, as applicable;
	 
	 	 	 	 	 	 
	 

	 	OS0
	 	=
	 	the number of shares of Common Stock outstanding immediately prior to
such Ex-Dividend Date or effective date, as applicable; and
	 
	 	 	 	 	 	 
	 

	 	OS1
	 	=
	 	the number of shares of Common Stock that would be outstanding
immediately after, and solely as a result of, such dividend, distribution, share
split or share combination.

Such adjustment shall become effective immediately after the opening of business on the Ex-Dividend
Date for such dividend or distribution, or the effective date for such share split or share
combination. If any dividend or distribution of the type described in this Section 5.04(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.

(b) If the Company, at any time or from time to time while any of the Securities are
outstanding, issues to all or substantially all holders of the Common Stock any rights or warrants
entitling them for a period of not more than 60 calendar days to subscribe for or purchase shares
of Common Stock, at a price per share less than the average of the Last Reported Sale Prices of
Common Stock for the 10 consecutive Trading-Day period ending on the Trading Day immediately
preceding the date of announcement of such issuance, the Applicable Conversion Rate shall be
adjusted based on the following formula:

 

43

 

where

	 	 	 	 	 	 	 
	 

	 	CR0
	 	=
	 	the Conversion Rate in effect immediately prior to the Ex-Dividend Date
for such issuance;
	 
	 	 	 	 	 	 
	 

	 	CR1
	 	=
	 	the Conversion Rate in effect immediately after the opening of business
on such Ex-Dividend Date;
	 
	 	 	 	 	 	 
	 

	 	OS0
	 	=
	 	the number of shares of Common Stock Outstanding immediately prior to
such Ex-Dividend Date;
	 
	 	 	 	 	 	 
	 

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

	 	Y
	 	=
	 	the number of shares of Common Stock equal to the aggregate price payable
to exercise such rights or warrants divided by the average of the Last Reported Sale
Prices of the Common Stock for the 10 consecutive Trading-Day period ending on the
Trading Day immediately preceding the date of announcement of the issuance of such
rights or warrants.

To the extent such rights or warrants are not exercised prior to their expiration or
termination, 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 or warrants been made on the basis
of the delivery of only the number of shares of Common Stock actually delivered. In the event that
such rights or warrants are not so issued, the Conversion Rate shall again be adjusted to be the
Conversion Rate which would then be in effect if the date fixed for the determination of
shareholders entitled to receive such rights or warrants had not been fixed. For the purposes of
this Section 5.04(b) in determining whether any rights or warrants entitle the holders to subscribe
for or purchase shares of Common Stock at less than the average of the Last Reported Sale Prices of
Common Stock for the 10 consecutive Trading-Day period ending on the Trading Day immediately
preceding the date of announcement of such issuance, and in determining the aggregate exercise
price payable for such shares of Common Stock, there shall be taken into account any consideration
received by the Company for such rights or warrants and any amount payable on exercise thereof,
with the value of such consideration, if other than cash, as shall be determined in good faith by
the Board of Directors of the Company.

 

44

 

For the purposes of this Section 5.04(b) (and subject in all respects to Section 5.12), rights or
warrants distributed by the Company to all holders of its Common Stock entitling them to subscribe
for or purchase shares of the Company’s Capital Stock (either initially or under certain
circumstances), which rights or warrants, until the
occurrence of a specified event or events (a “Trigger Event”): (1) are deemed to be transferred
with such shares of Common Stock; (2) are not exercisable; and (3) are also issued in respect of
future issuances of Common Stock, shall be deemed not to have been distributed for purposes of this
Section 5.04(b), (and no adjustment to the Conversion Rate under this Section 5.04(b) will be
required) until the occurrence of the earliest Trigger Event, whereupon such rights and warrants
shall be deemed to have been distributed and an appropriate adjustment (if any is required) to the
Conversion Rate shall be made under this Section 5.04(b). If any such right or warrant, including
any such existing rights or warrants distributed prior to the date of this Indenture, are subject
to events, upon the occurrence of which such rights 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 or warrants with such rights (and a termination or expiration of the existing rights
or warrants without exercise by any of the holders thereof). In addition, in the event of any
distribution (or deemed distribution) of rights or warrants, or any Trigger Event or other event
(of the type described in the preceding sentence) with respect thereto that was counted for
purposes of calculating a distribution amount for which an adjustment to the Conversion Rate under
this Section 5.04(b) was made, (1) in the case of any such rights or warrants which shall all have
been redeemed or purchased without exercise by any Holders thereof, the Conversion Rate shall be
readjusted upon such final purchase 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 purchase
price received by a holder of Common Stock with respect to such rights or warrants (assuming such
holder had retained such rights or warrants), made to all applicable holders of Common Stock as of
the date of such redemption or purchase, and (2) in the case of such rights or warrants which shall
have expired or been terminated without exercise by any holders thereof, the Conversion Rate shall
be readjusted as if such rights and warrants had not been issued.

(c) If the Company, at any time or from time to time while the Securities are outstanding,
distributes shares of any class of Capital Stock of the Company, evidences of its Indebtedness,
other assets or property of the Company or rights or warrants to acquire the Company’s Capital
Stock or other Securities to all or substantially all holders of its Common Stock, excluding:

(i) dividends or distributions referred to in Section 5.04(a) and rights or warrants
referred to in Section 5.04(b);

(ii) dividends or distributions paid exclusively in cash; and

(iii) Spin-offs to which provisions set forth below in this Section 5.04(c) shall
apply;

 

45

 

then the Applicable Conversion Rate shall be adjusted based on the following formula:

where

	 	 	 	 	 	 	 
	 

	 	CR0
	 	=	 	 the Conversion Rate in effect immediately prior to the Ex-Dividend Date
for such distribution;
	 
	 	 	 	 	 	 
	 

	 	CR1
	 	=	 	 the Conversion Rate in effect immediately after the opening of business
on such Ex-Dividend Date;
	 
	 	 	 	 	 	 
	 

	 	SP0
	 	=
	 	 the average of the Last Reported Sale Prices of the Common Stock over the
10 consecutive Trading-Day period ending on the Trading Day immediately preceding the
Ex-Dividend Date for such distribution; and
	 
	 	 	 	 	 	 
	 

	 	FMV
	 	=
	 	 the Fair Market Value (as determined by the Board of Directors of the
Company) of the shares of Capital Stock, evidences of Indebtedness, assets, property,
rights or warrants distributed with respect to each Outstanding share of the Common
Stock on the Ex-Dividend Date for such distribution.

Such adjustment shall become effective immediately after the opening of business on the Ex-Dividend
Date for such distribution. If the Board of Directors of the Company determines the Fair Market
Value of any distribution for purposes of this Section 5.04(c) by reference to the actual or
when-issued trading market for any securities, it must in doing so consider the prices in such
market over the same period used in computing the average of the Last Reported Sale Prices of the
Common Stock. Notwithstanding the foregoing, if “FMV” (as defined above) is equal to or greater
than “SP0” (as defined above), in lieu of the foregoing adjustment, adequate provision
shall be made so that each Securityholder shall receive on the date on which the relevant Capital
Stock, evidences of Indebtedness, other assets or property of the Company or rights or warrants to
acquire the Common Stock or other securities are distributed to holders of Common Stock, for each
$1,000 principal amount of Securities, the amount of Capital Stock, evidences of Indebtedness,
other assets or property of the Company or rights or warrants to acquire the Common Stock or other
securities such Securityholder would have received on the record date for such distribution had
such Securityholder owned a number of shares of Common Stock equal to the Conversion Rate as of the
Ex-Dividend Date for such distribution.

46

 

With respect to an adjustment pursuant to this Section 5.04(c) where there has been a payment
of a dividend or other distribution on the Common Stock of shares of Capital Stock of any class or
series, or similar equity interest, of or relating to a Subsidiary or other business unit (a
“Spin-Off”), the Applicable Conversion Rate shall be increased based on the following formula:

where

	 	 	 	 	 	 	 
	 

	 	CR0
	 	=	 	 the Conversion Rate in effect immediately prior to the end of the
Valuation Period;
	 
	 	 	 	 	 	 
	 

	 	CR1
	 	=	 	 the Conversion Rate in effect immediately after the end of the Valuation
Period;
	 
	 	 	 	 	 	 
	 

	 	FMV0
	 	=	 	 the average of the Last Reported Sale Prices of the Capital Stock or
similar equity interest distributed to holders of Common Stock applicable to one
share of Common Stock (determined for purposes of the definition of Last Reported
Sale Price as if such Capital Stock or similar equity interest were Common Stock)
over the first 10 consecutive Trading-Day period, and including, after the effective
date of the Spin-Off (the “Valuation Period”); and
	 
	 	 	 	 	 	 
	 

	 	MP0
	 	=	 	 the average of the Last Reported Sale Prices of Common Stock over the
Valuation Period.

The adjustment to the Conversion Rate under the preceding paragraph will occur on the last day
of the Valuation Period; provided that in respect of any conversion during the Valuation Period,
references above with respect to 10 Trading Days shall be deemed replaced with such lesser number
of Trading Days as have elapsed between the effective date of such Spin Off and the Conversion Date
in determining the Applicable Conversion Rate.

If any dividend or distribution of the type described in this Section 5.04(c) 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.

47

 

(d) If any cash dividend or other distribution is made to all, or substantially all, holders
of Common Stock, the Applicable Conversion Rate shall be adjusted based on the following formula:

where

	 	 	 	 	 	 	 
	 

	 	CR0
	 	=
	 	 the Conversion Rate in effect immediately prior to the Ex-Dividend Date
for such dividend or distribution;
	 
	 	 	 	 	 	 
	 

	 	CR1
	 	=
	 	 the Conversion Rate in effect immediately after the opening of business
on the Ex-Dividend Date for such dividend or distribution;
	 
	 	 	 	 	 	 
	 

	 	SP0
	 	=
	 	 the Last Reported Sale Price of a share of Common Stock on the Trading
Day immediately preceding the Ex-Dividend Date for such dividend or distribution; and
	 
	 	 	 	 	 	 
	 

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

In the case of an adjustment pursuant to this Section 5.04(d), such adjustment shall become
effective immediately after the opening of business on the Ex-Dividend Date for the relevant
dividend or distribution; provided that, if the portion of the cash so distributed applicable to
one share of Common Stock is equal to or greater than the Last Reported Sale Price of a share of
Common Stock on the Trading Day immediately preceding the Ex-Dividend Date for such dividend or
distribution, in lieu of the adjustment set forth in this Section 5.04(d) adequate provision shall
be made so that each Securityholder shall have the right to receive on the date on which such cash
dividend or distribution is distributed to holders of Common Stock, for each $1,000 principal
amount of Securities, the amount of cash such Holder would have received had such Holder owned a
number of shares equal to the Conversion Rate on the Ex-Dividend Date for such distribution.

If any dividend or distribution described in this Section 5.04(d) is declared but not so paid
or made, the Conversion Rate shall be readjusted to the Conversion Rate that would then be in
effect if such dividend or distribution had not been declared.

48

 

(e) If the Company or any of its Subsidiaries makes a payment in respect of a tender offer or
exchange offer for Common Stock to the extent that the cash and value of any other consideration
included in the payment per share of Common Stock exceeds the Last Reported Sale Price per share of
Common Stock on the Trading Day next succeeding the last date on which tenders or exchanges may be
made pursuant to such tender or exchange offer, the Applicable Conversion Rate shall be increased
based on the following formula:

where

	 	 	 	 	 	 	 
	 

	 	CR0
	 	=
	 	the Conversion Rate in effect immediately prior to the effective date of
the adjustment;
	 
	 	 	 	 	 	 
	 

	 	CR1
	 	=	 	the Conversion Rate in effect immediately after the opening of business
on the effective date of the adjustment;
	 
	 	 	 	 	 	 
	 

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

	 	OS0
	 	=
	 	the number of shares of Common Stock outstanding immediately prior to the
date such tender or exchange offer expires;
	 
	 	 	 	 	 	 
	 

	 	OS1
	 	=
	 	the number of shares of Common Stock outstanding immediately after the
date such tender or exchange offer expires (after giving effect to the purchase of
all shares accepted for purchase or exchange in such tender or exchange offer); and
	 
	 	 	 	 	 	 
	 

	 	SP1
	 	=
	 	the average of the Last Reported Sale Prices of Common Stock over the 10
consecutive Trading-Day period commencing on the Trading Day next succeeding the date
such tender or exchange offer expires.

The adjustment to the Conversion Rate under this Section 5.04(e) shall occur at the close of
business on the tenth Trading Day from, and including, the Trading Day next succeeding the date
such tender or exchange offer expires; provided that in respect of any conversion within 10 Trading
Days immediately following, and including, the expiration date of any tender or exchange offer,
references with respect to 10 Trading Days shall be deemed replaced with such lesser number of
Trading Days as have elapsed between the expiration date of such tender or exchange offer and the
Conversion Date in determining the Applicable Conversion Rate.

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

(f) “Ex-Dividend Date” shall mean the first date on which the shares of the Common Stock trade
on the applicable exchange or in the applicable market, regular way, without the right to receive
the issuance or distribution in question.

 

49

 

(g) For purposes of this Section 5.04, “record date” shall mean, with respect to any dividend,
distribution or other transaction or event in which the holders of Common Stock have the right to
receive any cash, securities or other property or in
which the Common Stock (or other applicable security) is exchanged for or converted into any
combination of cash, securities or other property, the date fixed for determination of shareholders
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 from time to time may increase the Conversion Rate by any amount for any
period of time if the period is at least 20 Business Days, the increase is irrevocable during the
period and the Board of Directors shall have made a determination that such increase would be in
the best interests of the Company, which determination shall be conclusive. Whenever the
Conversion Rate is increased pursuant to this Section 5.04(h), the Company shall mail to Holders of
record of the Securities a notice of the increase at least 15 days prior to the date the increased
Conversion Rate takes effect, and such notice shall state the increased Conversion Rate and the
period during which it will be in effect.

(i) The Company may make such increases in the Conversion Rate, in addition to any adjustments
required by Sections 5.04(a), 5.04(b), 5.04(c), 5.04(d), 5.04(e) or 5.04(h), as the Board of
Directors considers to be advisable to avoid or diminish any income tax to holders of Common Stock
or rights to purchase Common Stock resulting from any dividend or distribution of shares (or rights
to acquire shares) or from any event treated as such for income tax purposes.

(j) All calculations under this Article 5 shall be made by the Company and shall be made to
the nearest cent (including, in the case of any adjustment to the Conversion Rate, the resulting
adjustment to the Conversion Price) or to the nearest one-ten-thousandth of a share (with one-half
of a cent or five one-hundred-thousandths rounded upward), as the case may be. No adjustment shall
be made for the Company’s issuance of Common Stock or convertible or exchangeable securities for
shares of Common Stock or rights to purchase Common Stock or convertible or exchangeable
securities, other than as provided in this Section 5.04.

(k) Whenever the Conversion Rate is adjusted as herein provided, the Company shall promptly
file with the Trustee and any Conversion Agent an Officers’ Certificate setting forth the
Conversion Rate after such adjustment and setting forth a brief statement of the facts requiring
such adjustment. Unless and until a Responsible Officer of the Trustee shall have received such
Officers’ Certificate, the Trustee shall not be deemed to have knowledge of any adjustment of the
Conversion Rate and may assume without inquiry that the last Conversion Rate of which it has
knowledge is still in effect. Promptly after delivery of such certificate, the Company shall
prepare a notice of such adjustment of the Conversion Rate setting forth the adjusted Conversion
Rate and the date on which each adjustment becomes effective and shall mail such notice of such
adjustment of the Conversion Rate to each Securityholder at such Holder’s last address appearing on
the list of Securityholders provided for in Section 9.01, within 20 days after execution thereof.
Failure to deliver such notice shall not affect the legality or validity of any such adjustment.

 

50

 

(l) For purposes of this Section 5.04, the number of shares of Common Stock at any time
outstanding shall not include shares held in the treasury of the Company so long as the Company
does not pay any dividend or make any distribution on shares of Common Stock held in the treasury
of the Company, but shall include shares issuable in respect of scrip certificates issued in lieu
of fractions of shares of Common Stock.

(m) Notwithstanding the foregoing, if the application of the foregoing formulas would result
in a decrease in the Conversion Rate, no adjustment to the Conversion Rate shall be made (other
than as a result of a share split or a share combination).

(n) In the event of an adjustment to the Applicable Conversion Rate pursuant to Sections
5.04(d) or (e), in no event will the Applicable Conversion Rate exceed 40.0002 common shares per
$1,000 principal amount of Securities, in each case otherwise subject to adjustments as set forth
in Sections 5.04(a), (b) and (c).

(o) Notwithstanding anything to the contrary in this Article 5, no adjustment to the
Conversion Rate need be made for:

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

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

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

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

(v) accrued and unpaid interest on the Securities.

(p) No adjustment to the Conversion Rate shall be required unless the adjustment would require
an increase or decrease of at least 1% of the Conversion Rate. If an adjustment is not made
because the adjustment does not change the Conversion Rate by at least 1%, then such adjustment
will be carried forward and taken into account in any future adjustment. Notwithstanding the
foregoing, (i) upon any conversion of Securities (solely with respect to the Securities to be
converted), (ii) on every one-year anniversary from the Issue Date of the Securities and (iii) on
February 1, 2013, the Company shall give effect to all adjustments that the Company
has otherwise deferred pursuant to the immediately preceding sentence, and those adjustments
will no longer be carried forward and taken into account in any future adjustment.

 

51

 

Section 5.05. Adjustments of Average Prices. Whenever a provision of this Indenture
requires the calculation of an average of Last Reported Sale Prices or Daily VWAP over a span of
multiple days, the Company will make appropriate adjustments to account for any adjustment to the
Conversion Rate that becomes effective, or any event requiring an adjustment to the Conversion Rate
where the Ex-Dividend Date of the event occurs, at any time during the period from which the
average is to be calculated.

Section 5.06. Adjustments Upon Certain Fundamental Changes.

(a) If a Make-Whole Fundamental Change occurs and a Holder elects to convert its Securities in
connection with such Make-Whole Fundamental Change, the Company shall, under certain circumstances,
increase the Conversion Rate for the Securities so surrendered for conversion by a number of
additional shares of Common Stock (the “Additional Shares”) as described below. A conversion of
Securities shall be deemed for these purposes to be “in connection with” such Make-Whole
Fundamental Change if the notice of conversion of the Securities is received by the Conversion
Agent from, and including, the Scheduled Trading Day following the Effective Date of the Make-Whole
Fundamental Change up to, and including, the Business Day immediately prior to the related
Fundamental Change Repurchase Date (or, in the case of an event that would have been a Fundamental
Change but for the proviso in clause (2) of the definition thereof, the 35th Trading Day
immediately following the Effective Date of such Make-Whole Fundamental Change).

(b) The number of Additional Shares by which the Conversion Rate will be increased will be
determined by reference to the table attached as Schedule A hereto, based on the date on
which the Make-Whole Fundamental Change occurs or becomes effective (the “Effective Date”) and the
price (the “Stock Price”) paid per share of the Common Stock in the Make-Whole Fundamental Change.
If the holders of the Common Stock receive only cash in such Make-Whole Fundamental Change, the
Stock Price shall be the cash amount paid per share. Otherwise, the Stock Price shall be the
average of the Last Reported Sale Prices of Common Stock over the five Trading-Day period ending on
the Trading Day immediately preceding the Effective Date of the Make-Whole Fundamental Change.

(c) The Stock Prices set forth in the first row of the table in Schedule A hereto
shall be adjusted as of any date on which the Conversion Rate of the Securities is otherwise
adjusted. 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 such adjustment and the denominator of which is the Conversion Rate as so
adjusted. The number of Additional Shares set forth in such table shall be adjusted in the same
manner as the Conversion Rate as set forth in Section 5.04.

 

52

 

(d) The table in Schedule A hereto sets forth the hypothetical Stock Price, the
Effective Date and the number of Additional Shares to be added to the Conversion Rate per $1,000
principal amount of Securities.

The exact Stock Prices and Effective Dates may not be set forth in the table in
Schedule A, in which case:

(i) If the Stock Price is between two Stock Prices in the table or the Effective Date
is between two Effective Dates in the table, the number of Additional Shares shall be
determined by a straight-line interpolation between the number of Additional Shares set
forth for the higher and lower Stock Prices and the two dates, as applicable, based on a
365-day year.

(ii) If the Stock Price is greater than $150.00 per share (subject to adjustment in
the same manner as the Stock Prices set forth in the table in Schedule A pursuant to
clause (c)), no Additional Shares shall be added to the Conversion Rate.

(iii) If the Stock Price is less than $25.00 per share (subject to adjustments in the
same manner as the Stock Prices as set forth in the table in Schedule A pursuant to clause
(c), no Additional Shares shall be added to the Conversion Rate.

Notwithstanding the foregoing, in no event shall the total number of shares of Common Stock
issuable upon conversion exceed 40.0002 shares of Common Stock per $1,000 principal amount of
Securities, subject to adjustments in the same manner as the Conversion Rate as set forth in
Section 5.04.

Section 5.07. Effect of Recapitalization, Reclassification, Consolidation, Merger or Sale.
If any of the following events occur:

(i) any recapitalization, reclassification or change of shares of Common Stock
issuable upon conversion of the Securities (other than changes resulting from a
subdivision or combination);

(ii) any consolidation, merger or combination involving the Company; or

(iii) any sale, lease or other transfer of all or substantially all of the
consolidated properties and assets of the Company and its Subsidiaries to any other Person
or any statutory share exchange

in each case of clauses (i) — (iii) as a result of which the Common Stock would be
converted into, or exchanged for stock, other securities or other property or assets
(including cash or any combination thereof),

 

53

 

then at the effective time of such transaction, 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 Trust Indenture Act as in force at the date of execution of such supplemental indenture)
providing that the Securities shall be convertible into (x) cash in an amount equal to the portion
of the Settlement Amount comprised of cash in accordance with Section 5.03; and (y) in lieu of
shares of Common Stock otherwise deliverable, if any, the same type (in the same proportions) of
consideration received by a holder of Common Stock in connection with such recapitalization,
reclassification, change, consolidation, merger, combination, sale, lease, other transfer or share
exchange (collectively, “Reference Property”). After the effective time of any such transaction,
the amount of cash and Reference Property, if any, Holders of the Securities shall receive shall be
determined based on the Daily Settlement Amounts calculated with respect to a unit comprised of the
amount of Reference Property received by a holder of one share of Common Stock in such transaction,
the Daily VWAP of such unit of Reference Property and the Conversion Rate, as described in Section
5.03 (as if such unit of Reference Property were a share of Common Stock). If the transaction
causes Common Stock to be converted into the right to receive more than a single type of
consideration (determined based in part upon any form of stockholder election), the Reference
Property into which the Securities will be convertible shall be deemed to be the weighted average
of the types and amounts of consideration received by the holders of Common Stock that
affirmatively make such election. The Company shall not become a party to any such transaction
unless its terms are consistent with this Section 5.07. 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 5 in the judgment of the Board of Directors of the board of directors
of the successor Person. If, in the case of any such recapitalization, reclassification, change,
consolidation, merger, combination, sale, lease or other transfer, the stock, the Reference
Property receivable thereupon by a holder of Common Stock includes shares of stock, securities or
other property or assets (including cash or any combination thereof) of a corporation other than
the successor or purchasing corporation, as the case may be, in such reclassification, change,
consolidation, merger, combination, sale or conveyance, then such supplemental indenture shall also
be executed by such other corporation.

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 Security 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 5.07 shall similarly apply to successive reclassifications, changes,
consolidations, mergers, combinations, sales and conveyances. If this Section 5.07 applies to any
event or occurrence, Section 5.04 shall not apply.

 

54

 

Section 5.08. Taxes on Shares Issued. Any issue of stock certificates on conversions of
Securities shall be made without charge to the converting Holder for
any documentary, stamp or any similar issue or transfer tax 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 and delivery of shares of Common
Stock in any name other than that of the Holder of any Securities converted, and the Company shall
not be required to issue or deliver any such stock certificate unless and until the person or
persons requesting the issue thereof shall have paid to the Company the amount of such tax or shall
have established to the satisfaction of the Company that such tax has been paid.

Section 5.09. Reservation of Shares; Shares to be Fully Paid; Compliance With Governmental
Requirements; Listing of Common Stock. The Company shall provide, free from preemptive rights, out
of its authorized but unissued shares or shares held in treasury, sufficient shares of Common Stock
to satisfy conversion of the Securities from time to time as such Securities are presented for
conversion (assuming that, at the time of the computation of such number of shares or securities,
all such Securities would be converted by a single Holder).

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

The Company covenants that all shares of Common Stock that may be issued upon conversion of
Securities shall be newly issued shares or treasury shares, shall be duly authorized, validly
issued, fully paid and non-assessable and shall be free from preemptive rights and free from any
tax, lien or charge (other than those created by the Holder).

The Company shall list or cause to have quoted any shares of Common Stock to be issued upon
conversion of Securities on each national securities exchange or over-the-counter or other domestic
market on which the Common Stock is then listed or quoted.

Section 5.10. Responsibility of Trustee. The Trustee and any other Conversion Agent shall
not at any time be under any duty or responsibility to any Securityholder to determine the
Conversion Rate or whether any facts exist which may require any adjustment of the Conversion Rate,
or with respect to the nature or extent or calculation of any such adjustment when made, or with
respect to the method(s) employed (or herein or in any supplemental indenture provided to be
employed) in making the same. The Trustee and any other Conversion Agent shall not be accountable
with respect to the validity or value (or the kind or amount) of any shares of Common Stock, or of
any securities or property, which may at any time be
issued or delivered upon the conversion of any Securities; and the Trustee and any other
Conversion Agent make no representations with respect thereto.

 

55

 

Neither the Trustee nor any
Conversion Agent shall be responsible for any failure of the Company to issue, transfer or deliver
any shares of Common Stock or stock certificates or other securities or property or cash upon the
surrender of any Securities for the purpose of conversion or to comply with any of the duties,
responsibilities or covenants of the Company contained in this Article 5. Without limiting the
generality of the foregoing, neither the Trustee nor any Conversion Agent shall have any
responsibility to determine the correctness of any provisions contained in any supplemental
indenture entered into pursuant to Section 5.07 relating either to the kind or amount of shares of
stock or securities or property (including cash or any combination thereof) receivable by Holders
upon the conversion of their Securities after any event referred to in Section 5.07 or to any
adjustment to be made with respect thereto, but, subject to the provisions of Section 8.01, may
accept as conclusive evidence of the correctness of any such provisions, and shall be protected in
relying upon, the Officers’ Certificate (which the Company shall be obligated to file with the
Trustee prior to the execution of any such supplemental indenture) with respect thereto.

Section 5.11. Notice to Holders Prior to Certain Actions. Unless a notice has been provided
under Section 5.01(a)(iii) or Section 5.01(a)(iv), as applicable, in case:

(a) the Company shall declare a dividend (or any other distribution) on its Common Stock that
would require an adjustment in the Conversion Rate pursuant to Section 5.04; or

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

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

(d) of the voluntary or involuntary dissolution, liquidation or winding up of the Company or
any of its Designated Subsidiaries;

 

56

 

then, in each case, the Company shall cause to be filed with the Trustee and the Conversion Agent
and to be mailed to each Securityholder at such Holder’s address appearing on the list of
Securityholders provided for in Section 9.01 of this Indenture, as promptly as practicable but in
any event at least 30 days prior to the applicable
date hereinafter specified, a notice stating (x) the date on which a record is to be taken for the
purpose of such dividend, distribution or rights or warrants, or, if a record is not to be taken,
the date as of which the holders of Common Stock of record to be entitled to such dividend,
distribution or rights are to be determined, or (y) the date on which such reclassification,
consolidation, merger, sale, lease, transfer, dissolution, liquidation or winding up is expected to
become effective or occur, and the date as of which it is expected that holders of Common Stock of
record shall be entitled to exchange their Common Stock for securities or other property
deliverable upon such reclassification, consolidation, merger, sale, transfer, dissolution,
liquidation or winding up. Failure to give such notice, or any defect therein, shall not affect the
legality or validity of such dividend, distribution, reclassification, consolidation, merger, sale,
transfer, dissolution, liquidation or winding up.

Section 5.12. Stockholder Rights Plan. Each share of Common Stock issued upon conversion of
Securities pursuant to this Article 5 shall be entitled to receive the appropriate number of
rights, if any, and the certificates representing the Common Stock issued upon such conversion
shall bear such legends, if any, in each case as may be provided by the terms of any stockholder
rights plan adopted by the Company, as the same may be amended from time to time. If prior to any
conversion, however, such rights have separated from the shares of Common Stock in accordance with
the provisions of the applicable stockholder rights agreement, the Conversion Rate shall be
adjusted at the time of separation as if the Company distributed to all holders of the Common
Stock, shares of the Company’s Capital Stock, evidences of indebtedness, assets, property, rights
or warrants as described in Section 5.04(c), subject to readjustment in the event of the
expiration, termination or redemption of such rights.

Section 5.13. Company Determination Final. Any determination that the Company or the Board
of Directors must make pursuant to this Article 5 shall be conclusive if made in good faith, absent
manifest error.

ARTICLE 6

(b) default in the payment of interest on any Securities when due and payable and the default
continues for a period of 30 days;

 

57

and such default (subject to the provisions of Section 6.17) continues for a period of 60 days
after there has been given, by registered or certified mail, to the Company by the Trustee or to
the Company and the Trustee by the Holders of at least 25% in aggregate principal amount of the
Outstanding Securities a written notice, in each case received by the Company (and the Trustee, if
applicable), specifying such default and requiring it to be remedied and stating that such notice
is a “Notice of Default” hereunder;

(h) default by the Company or any Significant Subsidiary with respect to any mortgage,
agreement or other instrument under which there may be outstanding, or by which there may be
secured or evidenced, any Indebtedness for money borrowed in excess of $10 million in the aggregate
of the Company and/or any Significant Subsidiary, whether such indebtedness now exists or shall
hereafter be created (but excluding intercompany indebtedness) (i) resulting in such Indebtedness
becoming or being declared due and payable or (ii) constituting a failure to pay the principal
amount or interest of any such debt when due and payable at its stated maturity, upon required
repurchase, upon declaration or otherwise;

(i) the entry by a court having jurisdiction in the premises of (i) a decree or order for
relief in respect of the Company in an involuntary case or proceeding under any applicable federal

approving as properly filed a petition seeking reorganization, arrangement, adjustment or
composition of or in respect of the Company under any applicable federal or state law or (iii)
appointing a custodian, receiver, liquidator, assignee, trustee, sequestrator or other similar
official of the Company or of a Significant Subsidiary of the Company of any substantial part of
its property, or ordering the winding up or liquidation of its affairs, and the continuance of any
such decree or order for relief or any such other decree or order unstayed and in effect for a
period of 60 consecutive days;

 

58

 

(j) the commencement by the Company or by a Significant Subsidiary of the Company of a
voluntary case or proceeding under any applicable federal or state bankruptcy, insolvency,
reorganization or other similar law or of any other case or proceeding to be adjudicated a bankrupt
or insolvent, or the consent by it to the entry of a decree or order for relief in respect of the
Company or of a Significant Subsidiary of the Company in an involuntary case or proceeding under
any applicable federal or state bankruptcy, insolvency, reorganization or other similar law or to
the commencement of any bankruptcy or insolvency case or proceeding against it, or the filing by it
of a petition or answer or consent seeking reorganization or relief under any applicable federal or
state law, or the consent by it to the filing of such petition or to the appointment of or taking
possession by a custodian, receiver, liquidator, assignee, trustee, sequestrator or other similar
official of the Company or of a Significant Subsidiary of the Company or of any substantial part of
its property, or the making by it of an assignment for the benefit of creditors, or the admission
by it in writing of its inability to pay its debts generally as they become due, or the taking of
corporate action by the Company or by a Significant Subsidiary of the Company in furtherance of any
such action; or

(k) a final judgment for the payment (not covered by insurance) of $10 million or more

bonded off or stayed within 60 days after (i) the date on which the right to appeal thereof has
expired if no such appeal has commenced, or (ii) the date on which all rights to appeal have been
extinguished.

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

Section 6.02. Acceleration of Maturity; Rescission and Annulment.

(a) Subject to Section 6.17, if an Event of Default (other than those specified in Section
6.01(i) and 6.01(j)) occurs and is continuing, then and in every such case the Trustee or the
Holders of not less than 25% in aggregate principal amount of the Outstanding Securities may (and
the Trustee upon request of such Holders shall) declare the principal amount plus accrued and
unpaid interest, on all the Outstanding Securities to be due and payable immediately, by a notice
in writing to the Company (and to the Trustee if given by Holders), and upon any such declaration
such principal amount plus accrued and unpaid interest shall become immediately due and payable.

Notwithstanding the foregoing, in the case of an Event of Default specified in Section 6.01(i)
or Section 6.01(j), the principal amount plus accrued and unpaid interest on all Outstanding
Securities will ipso facto become due and payable immediately without any declaration or other act
on the part of the Trustee or any Holder.

 

59

 

(b) At any time after such a declaration of acceleration has been made, the Holders of a
majority in aggregate principal amount of the Outstanding Securities, by written notice to the
Company and the Trustee, may rescind and annul such declaration and its consequences (other than
with respect to an Event of Default under Sections 6.01(a), 6.01(b), 6.01(d) or 6.01(e)) if:

(i) such rescission and annulment will not conflict with any judgment or decree of a
court of competent jurisdiction; and

(ii) all Events of Default, other than the non-payment of the principal amount plus
accrued and unpaid interest on Securities that have become due solely by such declaration
of acceleration, have been cured or waived as provided in Section 6.12.

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

Section 6.03 . Collection of Indebtedness and Suits for Enforcement by Trustee. The Company
covenants that if a Default is made in the payment of the principal amount plus accrued and unpaid
interest at the Maturity thereof or in the payment of the Fundamental Change Repurchase Price in
respect of any Security, the Company will, upon demand of the Trustee, pay to it, for the benefit
of the Holders of such Securities, the whole amount then due and payable on such Securities, and,
in addition thereto, such further amounts required pursuant to Section 6.07.

If an Event of Default occurs and is continuing, the Trustee may, but shall not be obligated
to, pursue any available remedy to collect the payment of the principal amount plus accrued but
unpaid 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 the Trustee does not possess any
of the Securities or does not produce any of the Securities in the proceeding. A delay or omission
by the Trustee or any Holder in exercising any right or remedy accruing upon an Event of Default
shall not impair the right or remedy or constitute a waiver of, or acquiescence in, the Event of
Default. No remedy is exclusive of any other remedy. All available remedies are cumulative.

Section 6.04. Trustee May File Proofs of Claim. In case of any judicial proceeding relative
to the Company (or any other obligor upon the Securities), its property or its creditors, the
Trustee shall be entitled and empowered, by intervention in such proceeding or otherwise, to take
any and all actions authorized under the Trust Indenture Act in order to have claims of the Holders
and the Trustee allowed in any such proceeding. In particular, the Trustee shall be authorized to
collect and receive any moneys or other property payable or deliverable on any such claims and to
distribute the same; and any custodian, receiver, assignee, trustee, liquidator, sequestrator or
other similar official in any such judicial proceeding is hereby authorized by each Holder to make
such payments to the Trustee and, in the event that the Trustee shall consent to the making of such
payments directly to the Holders,
to pay to the Trustee any amount due it for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel and any other amounts due the
Trustee under Section 8.07.

 

60

 

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

Section 6.05. Application of Money Collected. Any money collected by the Trustee pursuant
to this Article shall be applied in the following order, at the date or dates fixed by the Trustee
and, in case of the distribution of such money to Holders, upon presentation of the Securities and
the notation thereon of the payment if only partially paid and upon surrender thereof if fully
paid:

FIRST: To the payment of all amounts due the Trustee under Section 8.07;

SECOND: To the payment of the amounts then due and unpaid on the Securities for the
principal amount, Fundamental Change Repurchase Price or interest, as the case may be, in
respect of which or for the benefit of which such money has been collected, ratably,
without preference or priority of any kind, according to the amounts due and payable on
such Securities; and

THIRD: To the payment of the remainder, if any, to the Company or any other Person
lawfully entitled thereto.

Section 6.06. Limitation on Suits. No Holder of any Security shall have any right to
institute any proceeding, judicial or otherwise, with respect to this Indenture, or for the
appointment of a receiver or trustee, or for any other remedy hereunder (other than in the case of
an Event of Default specified in Section 6.01(a) or Section 6.01(b)), unless:

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

(ii) the Holders of at least 25% in aggregate principal amount of the Outstanding
Securities shall have made written request to the Trustee to pursue such remedy in its own
name as Trustee hereunder;

(iii) no direction, in the opinion of the Trustee, inconsistent with such written
request has been given to the Trustee during such 60-day period by the Holders of a
majority in aggregate principal amount of the Outstanding Securities;

 

61

 

(iv) such Holder or Holders have provided to the Trustee security or indemnity
reasonably satisfactory to the Trustee against the expenses, losses and liabilities to be
incurred in compliance with such request; and

(v) the Trustee for 60 days after its receipt of such notice, request and provision
of adequate security or indemnity has failed to institute any such proceeding;

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

Section 6.07. Unconditional Right of Holders to Receive Payment. Notwithstanding any other
provision of this Indenture, the right of any Holder to receive payment of the principal amount,
Fundamental Change Repurchase Price or accrued and unpaid interest in respect of the Securities
held by such Holder, on or after the respective due dates expressed in the Securities or any
Fundamental Change Repurchase Date, as applicable, and to convert the Securities in accordance with
Article 5, or to bring suit for the enforcement of any such payment on or after such respective
dates or the right to convert, shall not be impaired or affected adversely without the consent of
such Holder.

Section 6.08. Restoration of Rights and Remedies. If the Trustee or any Holder has
instituted any proceeding to enforce any right or remedy under this Indenture and such proceeding
has been discontinued or abandoned for any reason, or has been determined adversely to the Trustee
or to such Holder, then and in every such case, subject to any determination in such proceeding,
the Company, the Trustee and the Holders shall be restored severally and respectively to their
former positions hereunder and thereafter all rights and remedies of the Trustee and the Holders
shall continue as though no such proceeding had been instituted.

Section 6.09. Rights and Remedies Cumulative. Except as otherwise provided with respect to
the replacement or payment of mutilated, destroyed, lost or stolen Securities in the last paragraph
of Section 2.12, no right or remedy herein conferred upon or reserved to the Trustee or to the
Holders is intended to be exclusive of any other right or remedy, and every right and remedy shall,
to the extent permitted by law, be cumulative and in addition to every other right and remedy given
hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or
employment of any right or remedy hereunder shall not prevent the concurrent assertion or
employment of any other appropriate right or remedy.

 

62

 

Section 6.10. Delay or Omission Not Waiver. No delay or omission of the Trustee or of any
Holder of any Security to exercise any right or remedy accruing upon any Event of Default shall
impair any such right or remedy or constitute a
waiver of any such Event of Default or an acquiescence therein. Every right and remedy given
by this Article or by law to the Trustee or to the Holders may be exercised from time to time, and
as often as may be deemed expedient, by the Trustee or by the Holders, as the case may be.

Section 6.11. Control by Holders. The Holders of a majority in principal amount of the
Outstanding Securities shall have the right to direct the time, method and place of conducting any
proceeding for any remedy available to the Trustee or exercising any trust or power conferred on
the Trustee, provided that:

(i) such direction shall not be in conflict with any rule of law or with this
Indenture; and

(ii) the Trustee may refuse to follow any such direction that the Trustee determines
is unduly prejudicial to the rights of any other Holder or that would involve the Trustee
in personal liability.

Section 6.12. Waiver of Past Defaults. The Holders of not less than a majority in principal
amount of the Outstanding Securities may on behalf of the Holders of all the Securities waive any
past Default hereunder and its consequences, except a Default:

(i) Described in Section 6.01(a) or Section 6.01(b); or

(ii) in respect of a covenant or provision hereof which under Article 11 cannot be
modified or amended without the consent of the Holder of each Outstanding Security
affected.

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

When a Default is waived, it is deemed cured, but no such waiver shall extend to any
subsequent or other Default or impair any consequent right. This Section 6.12 shall be in lieu of
Section 316(a)(1)(B) of the TIA and such Section 316(a)(1)(B) is hereby expressly excluded from
this Indenture, as permitted by the TIA.

Section 6.13. 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, in either case in respect of the Securities, a court may require any party litigant in
such suit to file an undertaking to pay the costs of the suit, and the court may assess reasonable
costs, including reasonable attorney’s 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; but the provisions of this Section 6.13 shall not apply to any suit instituted by the
Company,
to any suit instituted by the Trustee, to any suit instituted by any Holder, or group of
Holders, holding in the aggregate more than 10% in principal amount of the Outstanding Securities,
or to any suit instituted by any Holder for the enforcement of the payment of the principal amount
on any Security on or after Maturity of such Security or the Fundamental Change Repurchase Price.

 

63

 

Section 6.14. Waiver of Stay or Extension Laws. The Company covenants (to the extent that
it may lawfully do so) that it will not at any time insist upon, or plead, or in any manner
whatsoever claim or take the benefit or advantage of, any stay, extension or usury law or other law
which would prohibit or forgive the Company from paying all or any portion of the principal of or
interest on the Securities as contemplated herein, wherever enacted, now or at any time hereafter
in force, or which may affect the covenants or the performance of this Indenture; and the Company
(to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any
such law and covenants that it will not hinder, delay or impede the execution of any power herein
granted to the Trustee, but will suffer and permit the execution of every such power as though no
such law had been enacted.

Section 6.15. Violations of Certain Covenants. A violation of Section 3.06 or any other
covenant or agreement in this Indenture that expressly provides that a violation of such covenant
or agreement shall not constitute an Event of Default may only be enforced by the Trustee by
instituting a legal proceeding against the Company for enforcement of such covenant or agreement.

Section 6.16. Notice of Default. The Trustee may withhold notice to the Holders of the
Securities of any Event of Default, except defaults in payment of principal amount or interest on
the Securities, if and so long as a committee of the trust officers of the Trustee in good faith
determines that the withholding of such notice is in the interest of the Holders of the Securities.

Section 6.17. Alternative Remedy for Failure to Comply with Reporting Obligations in the
Indenture and TIA. Notwithstanding anything to the contrary in this Indenture, to the extent
elected by the Company in its sole discretion, the sole remedy for an Event of Default described in
Section 6.01(g) above relating to the failure to comply with Section 3.06 hereof or the failure to
comply with Section 314(a)(1) of the TIA, if applicable, will for the first 60 days after the
occurrence of such an Event of Default consist exclusively of the right to receive additional
interest on the Securities equal to 0.25% of the principal amount of the Securities (the “Default
Additional Interest”). This Default Additional Interest will be in addition to any Registration
Right Additional Interest on the Securities that may accrue as a result of a Registration Default
(as defined in the Registration Rights Agreement) and will be payable on the same dates and in the
same manner as interest accruing on the Securities. The Default Additional Interest will accrue on
all outstanding Securities from and including the date on which an Event of Default relating to the
failure to comply with Section 3.06 hereof or the failure to comply with Section 314(a)(1) of the
TIA first occurs to, but not including, the 60th day thereafter (or such earlier date on which the
Event of Default relating to the failure to
comply with Section 3.06 or the failure to comply with Section 314(a)(1) of the TIA shall have
been cured or waived).

 

64

 

On such 60th day (or earlier, if the Event of Default relating to the
failure to comply with Section 3.06 or the failure to comply with Section 314(a)(1) of the TIA is
cured or waived prior to such 60th day), such Default Additional Interest will cease to accrue and,
if the Event of Default relating to the failure to comply with Section 3.06 or the failure to
comply with Section 314(a)(1) of the TIA has not been cured or waived prior to such 60th day, the
Securities will be subject to acceleration as provided in Section 6.02 hereof. The provisions of
this paragraph will not affect the rights of Holders of Securities in the event of the occurrence
of any other Event of Default. In the event the Company does not timely elect to pay the
additional interest upon an Event of Default relating to the failure to comply with Section 3.06 or
the failure to comply with Section 314(a)(1) of the TIA in accordance with this paragraph, the
Securities will be subject to acceleration as provided in Section 6.02 hereof. To make such
election, the Company must notify the Holders, the Trustee and the Paying Agent of such election on
or prior to the date such failure to comply with Section 3.06 or the failure to comply with
Section 314(a)(1) of the TIA becomes an Event of Default.

ARTICLE 7

Consolidation, Merger, Conveyance, Transfer or Lease

Section 7.01. Company May Consolidate, etc., Only on Certain Terms. The Company shall not
consolidate with or merge with or into any other Person or convey, transfer or lease all or
substantially all its assets to another Person, unless:

(a) the resulting, surviving or transferee Person (if not the Company) (the “Successor
Company”) shall be a corporation organized and existing under (i) the laws of the United States of
America, any state thereof or the District of Columbia, or (ii) any other jurisdiction so long as
the Successor Company agrees to submit to service of process in any state in the United States of
America or the District of Columbia and, in the case of clause (ii) above, the Successor Company
provides a full and unconditional indemnity and provision for additional amounts required to be
withheld from payments or deliveries to Holders or beneficial owners of the Securities under
applicable United States or foreign laws, rules, regulations or authorities, and any other
incremental tax liabilities or costs of such Holders or beneficial owners as a result of such
merger or other transaction, and in each case the Successor Company (if not the Company) will
expressly assume, by a supplemental indenture, executed and delivered to the Trustee, in form
reasonably satisfactory to the Trustee, all of the Company’s obligations under the Securities and
this Indenture;

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

(c) the Company shall have delivered to the Trustee an Officers’ Certificate and an Opinion of
Counsel, each stating that such consolidation, merger or
transfer and, if a supplemental indenture is required in connection with such transaction,
such supplemental indenture, comply with this Article 7; and

 

65

 

(d) the Company shall have delivered to the Trustee an Opinion of Counsel to the effect that
the Holders or beneficial owners of the Securities will not recognize income, gain or loss for U.S.
federal income tax purposes as a result of such transaction and will be subject to U.S. federal
income tax in the same amount, in substantially the same manner and at the same times as would have
been the case if the transaction had not occurred, except where any of the foregoing are subject to
the indemnification provided for in Section 7.01(a) above.

For purposes of the foregoing, the transfer (by lease, assignment, sale or otherwise) of the
properties and assets of one or more Subsidiaries (other than to the Company or another
Subsidiary), which, if such assets were owned by the Company, would constitute all or substantially
all of the properties and assets of the Company and its Subsidiaries, taken as a whole, shall be
deemed to be the transfer of all or substantially all of the properties and assets of the Company.

The Successor Company formed by such consolidation or into which the Company is merged or the
Successor Company to which such conveyance, transfer, lease or other disposition is made shall
succeed to, and be substituted for, and may exercise every right and power of, the Company under
this Indenture with the same effect as if such successor had been named as the Company herein; and
thereafter, except in the case of a conveyance, transfer or lease of all or substantially all the
Company’s assets (in which case the Company will not be discharged from the obligation to pay the
principal amount of the Securities and interest, including any Additional Amounts) and except for
obligations, if any, that the Company may have under a supplemental indenture, the Company shall be
discharged from all obligations and covenants under this Indenture and the Securities. Subject to
Section 11.03, the Company, the Trustee and the Successor Company shall enter into a supplemental
indenture to evidence the succession and substitution of such Successor Company and such discharge
and release of the Company.

ARTICLE 8

The Trustee

Section 8.01. Duties and Responsibilities of Trustee. The Trustee, prior to the occurrence
of an Event of Default and after the curing of all Events of Default which may have occurred,
undertakes to perform such duties and only such duties as are specifically set forth in this
Indenture. In case an Event of Default has occurred (which has not been cured or waived), the
Trustee shall exercise such of the rights and powers vested in it by this Indenture, and use the
same degree of care and skill in their exercise, as a prudent person would exercise or use under
the circumstances in the conduct of his own affairs.

 

66

 

No provision of this Indenture shall be construed to relieve the Trustee from liability for
its own grossly negligent action, its own grossly negligent failure to act or its own willful
misconduct, except that:

(a) prior to the occurrence of an Event of Default and after the curing or waiving of all
Events of Default which may have occurred:

(i) the duties and obligations of the Trustee shall be determined solely by the
express provisions of this Indenture and the Trust Indenture Act, and the Trustee shall
not be liable except for the performance of such duties and obligations as are
specifically set forth in this Indenture and no implied covenants or obligations shall be
read into this Indenture and the Trust Indenture Act against the Trustee; and

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

(b) the Trustee shall not be liable for any error of judgment made in good faith by a
Responsible Officer or Officers of the Trustee, unless the Trustee was negligent in ascertaining
the pertinent facts;

it in good faith in accordance with the written direction of the Holders of not less than a
majority in principal amount of the Securities at the time outstanding determined as provided in
Section 1.04 relating to the time, method and place of conducting any proceeding for any remedy
available to the Trustee, or exercising any trust or power conferred upon the Trustee, under this
Indenture;

(d) whether or not therein provided, every provision of this Indenture relating to the conduct
or affecting the liability of, or affording protection to, the Trustee shall be subject to the
provisions of this Section 8.01;

amount, entitlement to receive or any other matters relating to payment) or notice effected by the
Company or any other paying agent or any records maintained by any co-registrar with respect to the
Securities; and

 

67

 

(f) if any party fails to deliver a notice relating to an event the fact of which, pursuant to
this Indenture, requires notice to be sent to the Trustee, the Trustee may conclusively rely on its
failure to receive such notice as reason to act as if no such event occurred.

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

Section 8.02. Notice of Defaults. The Trustee shall give the Holders notice of any Default
hereunder within 90 days after the occurrence thereof; provided, that (except in the case of any
Default in the payment of principal amount or interest on any of the Securities or Fundamental
Change Repurchase Price), the Trustee shall be protected in withholding such notice if and so long
as a committee of Responsible Officers of the Trustee in good faith determines that the withholding
of such notice is in the interest of the Holders of Securities.

Section 8.03. Reliance on Documents, Opinions, Etc. Except as otherwise provided in Section
8.01:

(a) the Trustee may rely and shall be protected in acting upon any resolution, certificate,
statement, instrument, opinion, report, notice, request, consent, order, bond, debenture, note,

good faith to be genuine and to have been signed or presented by the proper party or parties;

(b) any request, direction, order or demand of the Company mentioned herein shall be

herein specifically prescribed); and any resolution of the Board of Directors may be evidenced to
the Trustee by a copy thereof certified by the Secretary or an Assistant Secretary of the Company;

(c) the Trustee may consult with counsel of its own selection and any advice or Opinion of
Counsel shall be full and complete authorization and protection in respect of any action taken or
omitted by it hereunder in good faith and in accordance with such advice or Opinion of Counsel;

(d) the Trustee shall be under no obligation to exercise any of the rights or powers vested in
it by this Indenture at the request, order or direction of any of the Securityholders pursuant to
the provisions of this Indenture, unless such Securityholders shall have provided to the Trustee
security or indemnity reasonably satisfactory to the Trustee against the costs, expenses and
liabilities which may be incurred therein or thereby;

 

68

 

(e) 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 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
reasonable expense of the Company and the Trustee shall incur no liability of any kind by reason of
such inquiry or investigation);

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

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

(h) 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;

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

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

Section 8.04. No Responsibility for Recitals, Etc. The recitals contained herein and in the
Securities (except in the Trustee’s certificate of authentication) shall be taken as the statements
of the Company, and the Trustee assumes no responsibility for the correctness of the same. The
Trustee makes no representations as to the validity or sufficiency of this Indenture or of the
Securities. The Trustee shall not be accountable for the use or application by the Company of any
Securities or the proceeds of any Securities authenticated and delivered by the Trustee in
conformity with the provisions of this Indenture.

Section 8.05. Trustee, Paying Agents, Conversion Agents or Security Registrar May Own
Securities. The Trustee, any paying agent, any conversion agent or Security Registrar, in its
individual or any other capacity, may become the owner
or pledgee of Securities with the same rights it would have if it were not Trustee, paying
agent, conversion agent or Security Registrar.

 

69

 

Section 8.06. Monies to be Held in Trust. Subject to the provisions of Section 10.04, all
monies and properties received by the Trustee shall, until used or applied as herein provided, be
held in trust for the purposes for which they were received. Money held by the Trustee in trust
hereunder need not be segregated from other funds except to the extent required by law. The
Trustee shall have no liability for interest on any money received by it hereunder except as may be
agreed in writing from time to time by the Company and the Trustee.

Section 8.07. Compensation and Expenses of Trustee. The Company covenants and agrees to pay
to the Trustee from time to time, and the Trustee shall be entitled to, reasonable compensation for
all services rendered by it hereunder in any capacity (which shall not be limited by any provision
of law in regard to the compensation of a trustee of an express trust) as mutually agreed to from
time to time in writing between the Company and the Trustee, and the Company will pay or reimburse
the Trustee upon its request for all reasonable expenses, disbursements and advances reasonably
incurred or made by the Trustee in accordance with any of the provisions of this Indenture
(including the reasonable compensation and the expenses and disbursements of its counsel and of all
Persons not regularly in its employ) except any such expense, disbursement or advance as may arise
from its gross negligence, willful misconduct or bad faith. The Company also covenants to
indemnify the Trustee (and all officers, directors and employees of the Trustee), in any capacity
under this Indenture and its agents and any authenticating agent for, and to hold each of them
harmless against, any and all loss, liability, claim or expense incurred without gross negligence,
willful misconduct or bad faith on the part of the Trustee or such officer(s), director(s),
employee(s) and agent(s) or authenticating agent, as the case may be, and arising out of or in
connection with the acceptance or administration of this trust or in any other capacity hereunder,
including the costs and expenses of defending themselves against any claim of liability in the
premises. The obligations of the Company under this Section 8.07 to compensate or indemnify the
Trustee and to pay or reimburse the Trustee for expenses, disbursements and advances shall be
secured by a lien prior to that of the Securities upon all property and funds held or collected by
the Trustee as such, except funds held in trust for the benefit of the Holders of particular
Securities. The obligation of the Company under this Section 8.07 shall survive the satisfaction
and discharge of this Indenture.

When the Trustee and its agents and any authenticating agent incur expenses or render services
after an Event of Default specified in Section 6.01(i) or (j) with respect to the Company occurs,
the expenses and the compensation for the services are intended to constitute expenses of
administration under any bankruptcy, insolvency or similar laws.

Section 8.08. Officers’ Certificate as Evidence. Except as otherwise provided in Section
8.01, whenever in the administration of the provisions of this Indenture the Trustee shall deem it
necessary or desirable that a matter be proved or
established prior to taking or omitting any action hereunder, such matter (unless other
evidence in respect thereof be herein specifically prescribed) may, in the absence of negligence or
willful misconduct on the part of the Trustee, be deemed to be conclusively proved and established
by an Officers’ Certificate delivered to the Trustee.

 

70

 

Section 8.09. Conflicting Interests of Trustee. If the Trustee has or shall acquire a
conflicting interest within the meaning of the Trust Indenture Act, the Trustee shall either
eliminate such interest or resign, to the extent and in the manner provided by, and subject to the
provisions of, the Trust Indenture Act and this Indenture.

Section 8.10. Eligibility of Trustee. There shall at all times be a Trustee hereunder which
shall be a Person that is eligible pursuant to the Trust Indenture Act to act as such and has a
combined capital and surplus of at least $50,000,000 (or if such Person is a member of a bank
holding company system, its bank holding company shall have a combined capital and surplus of at
least $50,000,000). If such Person publishes reports of condition at least annually, pursuant to
law or to the requirements of any supervising or examining authority, then for the purposes of this
Section 8.10 the combined capital and surplus of such Person shall be deemed to be its combined
capital and surplus as set forth in its most recent report of condition so published. If at any
time the Trustee shall cease to be eligible in accordance with the provisions of this Section 8.10,
it shall resign immediately in the manner and with the effect hereinafter specified in this
Article.

Section 8.11. Resignation or Removal of Trustee.

(a) The Trustee may at any time resign by giving written notice of such resignation to the
Company and to the Holders of Securities. Upon receiving such notice of resignation, the Company
shall promptly appoint a successor trustee by written instrument, in duplicate, executed by order
of the Board of Directors, one copy of which instrument shall be delivered to the resigning Trustee
and one copy to the successor trustee. If no successor trustee shall have been so appointed and
have accepted appointment 60 days after the mailing of such notice of resignation to the
Securityholders, the resigning Trustee may, upon ten business days’ notice to the Company and the
Securityholders, appoint a successor identified in such notice or may petition, at the expense of
the Company, any court of competent jurisdiction for the appointment of a successor trustee, or,
any Securityholder who has been a bona fide Holder of a Security or Securities for at least 6
months may, subject to the provisions of Section 6.13, on behalf of himself and all others
similarly situated, petition any such court for the appointment of a successor trustee. Such court
may thereupon, after such notice, if any, as it may deem proper and prescribe, appoint a successor
trustee.

 

71

 

(b) In case at any time any of the following shall occur:

(i) the Trustee shall fail to comply with Section 8.09 after written request therefor
by the Company or by any Securityholder who has been a bona fide Holder of a Security or
Securities for at least 6 months; or

(ii) the Trustee shall cease to be eligible in accordance with the provisions of
Section 8.10 and shall fail to resign after written request therefor by the Company or by
any such Securityholder; or

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

then, in any such case, the Company may remove the Trustee and appoint a successor trustee by
written instrument, in duplicate, executed by order of the Board of Directors, one copy of which
instrument shall be delivered to the Trustee so removed and one copy to the successor trustee, or,
subject to the provisions of Section 6.13, any Securityholder who has been a bona fide Holder of a
Security or Securities for at least 6 months may, on behalf of himself and all others similarly
situated, petition any court of competent jurisdiction for the removal of the Trustee and the
appointment of a successor trustee; provided, however, that if no successor Trustee shall have been
appointed and have accepted appointment 60 days after either the Company or the Securityholders has
removed the Trustee, the Trustee so removed may petition at its own expense any court of competent
jurisdiction for an appointment of a successor trustee. Such court may thereupon, after such
notice, if any, as it may deem proper and prescribe, remove the Trustee and appoint a successor
trustee.

(c) The Holders of a majority in aggregate principal amount of the Securities at the time
outstanding may at any time remove the Trustee and nominate a successor trustee which shall be
deemed appointed as successor trustee unless, within ten days after notice to the Company of such
nomination, the Company objects thereto, in which case the Trustee so removed or any
Securityholder, or if such Trustee so removed or any Securityholder fails to act, the Company, upon
the terms and conditions and otherwise as in Section 8.11(a) provided, may petition any court of
competent jurisdiction for an appointment of a successor trustee.

(d) Any resignation or removal of the Trustee and appointment of a successor trustee pursuant
to any of the provisions of this Section 8.11 shall become effective upon acceptance of appointment
by the successor trustee as provided in Section 8.12.

 

72

 

Section 8.12. Acceptance by Successor Trustee. Any successor trustee appointed as provided
in Section 8.11 shall execute, acknowledge and deliver to the Company and to its predecessor
trustee an instrument accepting such appointment hereunder, and thereupon the resignation or
removal of the predecessor trustee shall become effective and such successor trustee, without any
further act, deed or
conveyance, shall become vested with all the rights, powers, duties and obligations of its
predecessor hereunder, with like effect as if originally named as trustee herein; but,
nevertheless, on the written request of the Company or of the successor trustee, the trustee
ceasing to act shall, upon payment of any amount then due it pursuant to the provisions of Section
8.07, execute and deliver an instrument transferring to such successor trustee all the rights and
powers of the trustee so ceasing to act. Upon request of any such successor trustee, the Company
shall execute any and all instruments in writing for more fully and certainly vesting in and
confirming to such successor trustee all such rights and powers. Any trustee ceasing to act shall,
nevertheless, retain a lien upon all property and funds held or collected by such trustee as such,
except for funds held in trust for the benefit of Holders of particular Securities, to secure any
amounts then due it pursuant to the provisions of Section 8.07.

No successor trustee shall accept appointment as provided in this Section 8.12 unless, at the
time of such acceptance, such successor trustee shall be qualified under the provisions of Section
8.09 and be eligible under the provisions of Section 8.10.

Upon acceptance of appointment by a successor trustee as provided in this Section 8.12, the
Company (or the former trustee, at the written direction of the Company) shall mail or cause to be
mailed notice of the succession of such trustee hereunder to the Holders of Securities at their
addresses as they shall appear on the Security Register. If the Company fails to mail such notice
within ten days after acceptance of appointment by the successor trustee, the successor trustee
shall cause such notice to be mailed at the expense of the Company.

Section 8.13. Succession by Merger, Etc. Any corporation into which the Trustee may be
merged or converted or with which it may be consolidated, or any corporation resulting from any
merger, conversion or consolidation to which the Trustee shall be a party, or any corporation
succeeding to all or substantially all of the corporate trust business of the Trustee (including
any trust created by this Indenture), shall be the successor to the Trustee hereunder without the
execution or filing of any paper or any further act on the part of any of the parties hereto,
provided that in the case of any corporation succeeding to all or substantially all of the
corporate trust business of the Trustee, such corporation shall be qualified under the provisions
of Section 8.09 and eligible under the provisions of Section 8.10.

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

 

73

 

Section 8.14. Preferential Collection of Claims. If and when the Trustee shall be or become
a creditor of the Company (or any other obligor upon the Securities), the Trustee shall be subject
to the provisions of the Trust Indenture Act regarding the collection of the claims against the
Company (or any such other obligor).

Section 8.15. Trustee’s Application for Instructions from the Company. Any application by
the Trustee for written instructions from the Company (other than with regard to any action
proposed to be taken or omitted to be taken by the Trustee that affects the rights of the Holders
of the Securities under this Indenture) may, at the option of the Trustee, set forth in writing any
action proposed to be taken or omitted by the Trustee under this Indenture and the date on and/or
after which such action shall be taken or such omission shall be effective. The Trustee shall not
be liable for any action taken by, or omission of, the Trustee in accordance with a proposal
included in such application on or after the date specified in such application (which date shall
not be less than three Business Days after the date any officer of the Company actually receives
such application, unless any such officer shall have consented in writing to any earlier date)
unless prior to taking any such action (or the effective date in the case of an omission), the
Trustee shall have received written instructions in response to such application specifying the
action to be taken or omitted.

as the Trustee may reasonably require, of the names and addresses of the Holders as of
such Record Date; and

(ii) at such other times as the Trustee may request in writing, within 30 days after

and addresses of Holders contained in the most recent list furnished to the Trustee as provided in
Section 9.01 and the names and addresses of Holders received by the Trustee in its capacity as
Security Registrar. The Trustee may destroy any list furnished to it as provided in Section 9.01
upon receipt of a new list so furnished.

(b) The rights of Holders to communicate with other Holders with respect to their rights under
this Indenture or under the Securities, and the corresponding rights and duties of the Trustee,
shall be as provided by the Trust Indenture Act.

Trustee that neither the Company nor the Trustee nor any agent of either of them shall be held
accountable by reason of any disclosure of information as to names and addresses of Holders made
pursuant to the Trust Indenture Act.

Section 9.03. Reports By Trustee. The Trustee shall transmit to Holders such reports
concerning the Trustee and its actions under this Indenture as may be required pursuant to the
Trust Indenture Act at the times and in the manner provided pursuant thereto. Reports so required
to be transmitted at stated intervals of not more than 12 months shall be transmitted no later than

as of a date not more than 60 days prior to the date of transmission.

(a) A copy of each such report shall, at the time of such transmission to Holders, be filed by

listed on any stock exchange or of any delisting thereof.

Section 9.04. Reports by Company.

(a) After this Indenture has been qualified under the Trust Indenture Act, the Company shall
file with the Trustee and the Commission, and transmit to Securityholders, such information,
documents and other reports and such summaries thereof, as may be required pursuant to the Trust
Indenture Act at the times and in the manner provided pursuant to such Act; provided that any such
information, documents or reports filed with the Commission pursuant to Section 13 or 15(d) of the
Exchange Act shall be filed with the Trustee within 15 days after the same is filed with the
Commission. To the extent any such information, documents and reports are filed by the Company
electronically on the Commission’s Electronic Data Gathering and Retrieval System (or any successor
system), notice thereof shall be delivered promptly to the Trustee, upon which such information,
documents and reports shall be deemed delivered to the Trustee.

 

75

 

(b) 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
conclusively rely exclusively on an Officers’ Certificate). It is expressly understood that
materials transmitted electronically by the Company to the Trustee shall be deemed filed with the
Trustee for purposes of this Section 9.04.

destroyed, lost or stolen and in lieu of or in substitution for which other Securities shall have
been authenticated and delivered) and not theretofore canceled, or (b) all the Securities not
theretofore canceled or delivered to the Trustee for cancellation shall have become due and payable
(whether at Stated Maturity, or on any Fundamental Change Repurchase Date or upon conversion or
otherwise) and the Company shall deposit with the Trustee, in trust, cash funds and shares of
Common Stock, as applicable, sufficient to pay all amounts due (and shares of Common Stock
deliverable following conversion, if applicable) on all of such Securities (other than any

substitution for which other Securities shall have been authenticated and delivered) not
theretofore canceled or delivered to the Trustee for cancellation, including principal and interest
due, accompanied, except in the event the Securities are due and payable solely in cash upon a
Fundamental Change Repurchase Date, by a verification report as to the sufficiency of the deposited
amount from an independent certified accountant or other financial professional satisfactory to the
Trustee, and if the Company shall also pay or cause to be paid all other sums payable hereunder by
the Company, then this Indenture shall cease to be of further effect (except as to (i) remaining
rights of registration of transfer, substitution and exchange and conversion of Securities, (ii)
rights hereunder of Securityholders to receive payments of principal of and interest on, the
Securities and the other rights, duties and obligations of Securityholders, as beneficiaries hereof
with respect to the amounts, if any, so deposited with the Trustee and (iii) the rights,
obligations and immunities of the Trustee hereunder), and the Trustee, on written demand of the
Company accompanied by an Officers’ Certificate and an Opinion of Counsel as required by Section
1.02 and at the cost and expense of the Company, shall execute proper instruments acknowledging
satisfaction and discharge of this Indenture; the Company, however, hereby agrees to reimburse the
Trustee for any costs or expenses thereafter reasonably and properly incurred by the Trustee and to
compensate the Trustee for any services thereafter reasonably and properly rendered by the Trustee
in connection with this Indenture or the Securities.

 

76

 

Section 10.02. Deposited Monies to be Held in Trust by Trustee. Subject to Section 10.04,
all monies deposited with the Trustee pursuant to Section 10.01 shall be held in trust for the sole
benefit of the Securityholders, and such monies shall be applied by the Trustee to the payment,
either directly or through any paying agent (including the Company if acting as its own paying
agent), to the Holders of the particular Securities for the payment of which such monies have been
deposited with the Trustee, of all sums due and to become due thereon for principal and interest.

Section 10.03 . Paying Agent to Repay Monies Held. Upon the satisfaction and discharge of
this Indenture, all monies then held by any paying agent of the Securities (other than the Trustee)
shall, upon written request of the Company, be repaid to it or paid to the Trustee, and thereupon
such paying agent shall be released from all further liability with respect to such monies.

Section 10.04 . Return of Unclaimed Monies. Subject to the requirements of applicable law,
any monies deposited with or paid to the Trustee for payment of the principal of or interest on
Securities and not applied but remaining unclaimed by the Holders of Securities for two years after
the date upon which the principal of or interest on such Securities, as the case may be, shall have
become due and payable, shall be repaid to the Company by the Trustee on demand and all liability
of the Trustee shall thereupon cease with respect to such monies; and the Holder of any of the
Securities shall thereafter look only to the Company for any payment that such Holder may be
entitled to collect unless an applicable abandoned property law designates another Person.

Section 10.05 . Reinstatement. If the Trustee or the paying agent is unable to apply any
money in accordance with Section 10.02 by reason of any order or judgment of any court or
governmental authority enjoining, restraining or otherwise prohibiting such application, the
Company’s obligations under this Indenture and the Securities shall be revived and reinstated as
though no deposit had occurred pursuant to Section 10.01 until such time as the Trustee or the
paying agent is permitted to apply all such money in accordance with Section 10.02; provided,
however, that if the Company makes any payment of interest on or principal of any Security
following the reinstatement of its obligations, the Company shall be subrogated to the rights of
the Holders of such Securities to receive such payment from the money held by the Trustee or paying
agent.

5.00% Convertible Senior Note due 2013

1. Interest

(a) GMX RESOURCES INC., an Oklahoma corporation (such corporation, and its successors and
assigns under the Indenture hereinafter referred to, being herein called the “Company”), promises
to pay interest on the principal amount of this Security at the rate of 5.00% per annum. The
Company will pay interest semiannually on February 1 and August 1 of each year commencing on August
1, 2008. Interest on the Security will accrue from the most recent date to which interest has been
paid or, if no interest has been paid, from February 15, 2008. Interest will be computed on the
basis of a 360-day year of twelve 30-day months. If a payment date is not a Business Day, payment
will be made on the next succeeding Business Day, and no additional interest will accrue in respect
of such payment by virtue of the payment being made on such later date.

(b) The Holder of this Security is entitled to the benefits of a Registration Rights
Agreement, dated as of February 15, 2008, among the Company, and the Initial Purchasers named
therein (the “Registration Rights Agreement”) providing for the payment of additional interest.
The Company may also elect to pay additional interest on this Security as a remedy for an Event of
Default relating to a failure to file with the Trustee reports required under the Exchange Act.

(c) Except as otherwise specifically set forth, all references herein to “interest” include
Additional Interest under the Registration Rights Agreement and additional interest that the
Company elects to pay in connection with a failure to file reports required under the Exchange Act.

2. Paying Agent, Registrar and Conversion Agent

Initially, The Bank of New York, Trust Company, N.A., a national banking association (the
“Trustee”), will act as Paying Agent, Registrar and Conversion Agent. The Company may appoint and
change any Paying Agent, Registrar or co-registrar or Conversion Agent without notice. The Company
or any of its domestically incorporated wholly owned Subsidiaries may act as Paying Agent,
Registrar or co-registrar, or Conversion Agent.

3. Indenture

The Company issued the Securities under an Indenture dated as of February 15, 2008 (the
“Indenture”), between the Company and the Trustee. The terms of the Securities include those
stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture
Act of 1939 as in effect on the date of the Indenture (the “TIA”). Terms defined in the Indenture
and not defined herein have the meanings ascribed thereto in the Indenture. The Securities are
subject to all such terms, and Securityholders are referred to the Indenture and the TIA for a
statement of those terms.

 

A-6

 

This Security is one of the Securities referred to in the Indenture issued in an initial
aggregate principal amount of $125 million. Additional Securities may be issued in accordance with
the Indenture. The Indenture also imposes limitations on the ability of the Company to consolidate
or merge with or into any other Person or convey, transfer or lease all or substantially all of the
property of the Company.

4. Conversion

Upon the occurrence of certain events specified in the Indenture and in compliance with the
provisions of the Indenture, on or prior to the close of business on the Business Day immediately
preceding the Maturity Date of this Security, the Holder hereof has the right, at its option, to
convert each $1,000 principal amount of this Security into a combination of cash and Common Stock,
determined as set forth in the Indenture, based on an initial Conversion Rate of 30.7692 shares of
Common Stock per $1,000 principal amount of Securities, as the same may be adjusted pursuant to the
terms of the Indenture.

5. Denominations, Transfer, Exchange

The Securities are in registered form without coupons in denominations of $1,000 and whole
multiples of $1,000. A Securityholder may transfer or exchange Securities in accordance with the
Indenture. Upon any transfer or exchange, the Registrar and the Trustee may require a
Securityholder, among other things, to furnish appropriate endorsements or transfer documents and
to pay any taxes required by law or permitted by the Indenture.

6. Persons Deemed Owners

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

7. Defaults and Remedies

If an Event of Default (other than an Event of Default relating to certain events of
bankruptcy, insolvency or reorganization of the Company) occurs and is continuing, the Trustee or
the Holders of at least 25% in principal amount of the outstanding Securities may declare the
principal of and accrued but unpaid interest on all the Securities to be due and payable. If an
Event of Default relating to certain events of bankruptcy, insolvency or reorganization of the
Company or any of its Significant Subsidiaries occurs, the principal of and interest on all the
Securities will become immediately due and payable without any declaration or other act on the part
of the Trustee or any Securityholder.

8. No Recourse Against Others

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

authenticating agent) manually signs the certificate of authentication on the other side of this
Security.

TEN COM (=tenants in common), TEN ENT (=tenants by the entireties), JT TEN (=joint tenants with
rights of survivorship and not as tenants in common), CUST (=custodian), and U/G/M/A (=Uniform Gift
to Minors Act).

11. GOVERNING LAW

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

12. CUSIP and ISIN Numbers

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

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