part of this Indenture. To the extent applicable, the Company and the Trustee, by their execution
and delivery of this Indenture, expressly agree to such terms and provisions and to be bound
thereby.

          Any Global Note may be endorsed with or have incorporated in the text thereof such legends or
recitals or changes not inconsistent with the provisions of this Indenture as may be required by
the Custodian or the Depositary, or as may be required to comply with any applicable law or any
regulation thereunder or with the rules and regulations of any securities exchange or automated
quotation system upon which the Notes may be listed or traded or designated for issuance or to

of this Indenture, or as may be required to comply with any law or with any rule or regulation made
pursuant thereto or with any rule or regulation of any securities exchange or automated quotation
system on which the Notes may be listed or designated for issuance, or to conform to usage or to

360-day year composed of twelve 30-day months.

          (b) The Person in whose name any Note (or its Predecessor Note) is registered on the Note
Register at the close of business on any Regular Record Date with respect to any Interest Payment
Date shall be entitled to receive the interest payable on such Interest Payment Date. Interest
shall be payable at the office or agency of the Company maintained by the Company for such purposes
in the Borough of Manhattan, The City of New York, which shall initially be the Corporate Trust
Office. The Company shall pay interest (i) on any Physical Notes (A) to Holders holding Physical

these Notes at their address as it appears in the Note Register and (B) to Holders holding Physical
Notes having an aggregate principal amount of more than $5,000,000, either by check mailed to such
Holders or, upon application by such Holder to the Note Registrar not later than the relevant
Regular Record Date, by wire transfer in immediately available funds to that Holder’s account
within the United States, which application shall remain in effect until the Holder notifies, in
writing, the Note Registrar to the contrary or (ii) on any Global Note by wire transfer of
immediately available funds to the account of the Depositary or its nominee.

          (c) Any Defaulted Amounts shall forthwith cease to be payable to the Holder on the relevant
payment date but shall accrue interest per annum at the rate borne by the Notes, subject to the
enforceability thereof under applicable law, from, and including, such relevant payment date, and
such Defaulted Amounts together with such interest thereon shall be paid by the Company, at its
election in each case, as provided in clause (i) or (ii) below:

          (i) The Company may elect to make payment of any Defaulted Amounts to the Persons in
whose names the Notes (or their respective Predecessor Notes) are registered at the close of
business on a special record date for the payment of such Defaulted Amounts, which shall be
fixed in the following manner. The Company shall notify the Trustee in writing of the
amount of the Defaulted Amounts proposed to be paid on each Note and the date of the
proposed payment (which shall be not less than 25 days after the receipt by the Trustee of
such notice, unless the Trustee shall consent in writing to an earlier date), and at the
same time the Company shall deposit with the Trustee an amount of money equal to the
aggregate amount to be paid in respect of such Defaulted Amounts or shall make arrangements
satisfactory to the Trustee for such deposit on or prior to the date of the proposed
payment, such money when deposited to be held in trust for the benefit of the Persons
entitled to such Defaulted Amounts as in this clause provided. Thereupon the Company shall
fix a special record date for the payment of such Defaulted Amounts which shall be not more
than 15 days and not less than 10 days prior to the date of the proposed payment, and not
less than 10 days after the receipt by the Trustee of the notice of the proposed payment.
The Company shall promptly notify the Trustee in writing of such special record date and the
Trustee, in the name and at the expense of the Company, shall cause notice of the proposed
payment of such Defaulted

13

 

Amounts and the special record date therefor to be mailed,
first-class postage prepaid, to each Holder at its address as it appears in the Note
Register, not less than 10 days prior to such special record date. Notice of the proposed
payment of such Defaulted Amounts and the special record date therefor having been so
mailed, such Defaulted Amounts shall be paid to the Persons in whose names the Notes (or
their respective Predecessor Notes) are registered at the close of business on such special
record date and shall no longer be payable pursuant to the following clause (ii) of this
Section 2.03(c).

          (ii) The Company may make payment of any Defaulted Amounts in any other lawful manner
not inconsistent with the requirements of any securities exchange or automated quotation
system on which the Notes may be listed or designated for issuance, and upon such notice as
may be required by such exchange or automated quotation system, if, after written notice
given by the Company to the Trustee of the proposed payment pursuant to this clause, such
manner of payment shall be deemed practicable by the Trustee.

          Section 2.04. Execution, Authentication and Delivery of Notes. The Notes shall be signed in
the name and on behalf of the Company by the manual or facsimile signature of its Chief Executive
Officer, President, Chief Financial Officer, Treasurer, Secretary or any of its Vice Presidents.

          At any time and from time to time after the execution and delivery of this Indenture, the
Company may deliver Notes executed by the Company to the Trustee for authentication, together with
a Company Order for the authentication and delivery of such Notes, and the Trustee in accordance
with such Company Order shall authenticate and deliver such Notes, without any further action by
the Company hereunder.

          Only such Notes as shall bear thereon a certificate of authentication substantially in the
form set forth on the form of Note attached as Exhibit A hereto, executed manually by an authorized
officer of the Trustee (or an authenticating agent appointed by the Trustee as provided by Section
17.10), shall be entitled to the benefits of this Indenture or be valid or obligatory for any
purpose. Such certificate by the Trustee (or such an authenticating agent) upon any Note executed
by the Company shall be conclusive evidence that the Note so authenticated has been duly
authenticated and delivered hereunder and that the Holder is entitled to the benefits of this
Indenture.

          In case any Officer of the Company who shall have signed any of the Notes shall cease to be
such Officer before the Notes so signed shall have been authenticated and delivered by the Trustee,
or disposed of by the Company, such Notes nevertheless may be authenticated and delivered or
disposed of as though the person who signed such Notes had not ceased to be such Officer of the
Company; and any Note may be signed on behalf of the Company by such persons as, at the actual date
of the execution of such Note, shall be the Officers of the Company, although at the date of the
execution of this Indenture any such person was not such an Officer.

it may prescribe, the Company shall provide for the registration of Notes and of transfers of
Notes. Such register shall be in written form or in any form capable of being converted into
written form within a reasonable period of time. The Trustee is hereby initially appointed the
“Note Registrar” for the purpose of registering Notes and transfers of Notes as herein provided.
The Company may appoint one or more co-Note Registrars in accordance with Section 4.02.

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

          Notes may be exchanged for other Notes of any authorized denominations and of a like aggregate
principal amount, upon surrender of the Notes to be exchanged at any such office or agency
maintained by the Company pursuant to Section 4.02. Whenever any Notes are so surrendered for
exchange, the Company shall execute, and the Trustee shall authenticate and deliver, the Notes that
the Holder making the exchange is entitled to receive, bearing registration numbers not
contemporaneously outstanding.

          All Notes presented or surrendered for registration of transfer or for exchange, repurchase or
conversion shall (if so required by the Company, the Trustee, the Note Registrar or any co-Note
Registrar) be duly endorsed, or be accompanied by a written instrument or instruments of transfer
in form satisfactory to the Company and duly executed, by the Holder thereof or its
attorney-in-fact duly authorized in writing.

          No service charge shall be imposed by the Company, the Trustee, the Note Registrar or any
co-Note Registrar for any exchange or registration of transfer of Notes, but the Company or the
Trustee may require a Holder to pay a sum sufficient to cover any documentary, stamp or similar
issue or transfer tax required by law or permitted pursuant to Section 14.02(d) or Section
14.02(e).

          None of the Company, the Trustee, the Note Registrar or any co-Note Registrar shall be
required to exchange or register a transfer of (i) any Notes surrendered for conversion or, if a
portion of any Note is surrendered for conversion, such portion thereof surrendered for conversion
or (ii) any Notes, or a portion of any Note, surrendered for repurchase (and not withdrawn) in
accordance with Article 15.

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

          (b) So long as the Notes are eligible for book-entry settlement with the Depositary, unless
otherwise required by law, subject to the fourth paragraph from the end of Section 2.05(c) all
Notes shall be represented by one or more Notes in global form (each, a “Global Note”)

15

 

registered in the name of the Depositary or a nominee of the Depositary. The transfer and exchange of
beneficial interests in a Global Note that does not involve the issuance of a Physical Note shall
be effected through the Depositary (but not the Trustee or the Custodian) in accordance with this
Indenture (including the restrictions on transfer set forth herein) and the procedures of the
Depositary therefor.

          (c) Every Note that bears or is required under this Section 2.05(c) to bear the legend set
forth in this Section 2.05(c) (together with any Common Stock issued upon conversion of the Notes
and required to bear the legend set forth in Section 2.05(d), collectively, the “Restricted
Securities”) shall be subject to the restrictions on transfer set forth in this Section 2.05(c)
(including the legend set forth below), unless such restrictions on transfer shall be eliminated or
otherwise waived by written consent of the Company, and the Holder of each such Restricted
Security, by such Holder’s acceptance thereof, agrees to be bound by all such restrictions on
transfer. As used in this Section 2.05(c) and Section 2.05(d), the term “transfer” encompasses any
sale, pledge, transfer or other disposition whatsoever of any Restricted Security.

          Until the date (the “Resale Restriction Termination Date”) that is the later of (1) the date
that is one year after the last date of original issuance of the Notes, or such shorter period of
time as permitted by Rule 144 under the Securities Act or any successor provision thereto, and (2)
such later date, if any, as may be required by applicable law, any certificate evidencing such Note
(and all securities issued in exchange therefor or substitution thereof, other than Common Stock,
if any, issued upon conversion thereof which shall bear the legend set forth in Section 2.05(d), if
applicable) shall bear a legend in substantially the following form (unless such Notes have been
transferred pursuant to a registration statement that has become or been declared effective under
the Securities Act and that continues to be effective at the time of such transfer, or sold
pursuant to the exemption from registration provided by Rule 144 or any similar provision then in
force under the Securities Act, or unless otherwise agreed by the Company in writing, with notice
thereof to the Trustee):

          THIS SECURITY AND THE COMMON STOCK, IF ANY, ISSUABLE UPON CONVERSION OF THIS SECURITY HAVE NOT
BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND MAY NOT BE
OFFERED, SOLD, PLEDGED OR OTHERWISE TRANSFERRED EXCEPT IN ACCORDANCE WITH THE FOLLOWING SENTENCE.
BY ITS ACQUISITION HEREOF OR OF A BENEFICIAL INTEREST HEREIN, THE ACQUIRER:

          (1) REPRESENTS THAT IT AND ANY ACCOUNT FOR WHICH IT IS ACTING IS A “QUALIFIED
INSTITUTIONAL BUYER” (WITHIN THE MEANING OF RULE 144A UNDER THE SECURITIES ACT) AND THAT IT
EXERCISES SOLE INVESTMENT DISCRETION WITH RESPECT TO EACH SUCH ACCOUNT, AND

          (2) AGREES FOR THE BENEFIT OF INTEGRA LIFESCIENCES HOLDINGS CORPORATION (THE “COMPANY”)
THAT IT WILL NOT OFFER, SELL, PLEDGE OR OTHERWISE TRANSFER THIS SECURITY OR ANY BENEFICIAL
INTEREST HEREIN PRIOR TO THE DATE THAT IS THE LATER OF (X) ONE YEAR AFTER THE LAST ORIGINAL
ISSUE DATE HEREOF OR SUCH SHORTER PERIOD OF TIME AS PERMITTED BY RULE 144 UNDER THE

16

 

SECURITIES ACT OR ANY SUCCESSOR PROVISION THERETO, AND (Y) SUCH LATER DATE, IF ANY, AS MAY
BE REQUIRED BY APPLICABLE LAW, EXCEPT:

          (A) TO THE COMPANY OR ANY SUBSIDIARY THEREOF, OR

          (B) PURSUANT TO A REGISTRATION STATEMENT WHICH HAS BECOME EFFECTIVE UNDER THE
SECURITIES ACT, OR

          (C) TO A QUALIFIED INSTITUTIONAL BUYER IN COMPLIANCE WITH RULE 144A UNDER THE
SECURITIES ACT, OR

          (D) PURSUANT TO AN EXEMPTION FROM REGISTRATION PROVIDED BY RULE 144 UNDER THE
SECURITIES ACT OR ANY OTHER AVAILABLE EXEMPTION FROM THE REGISTRATION REQUIREMENTS
OF THE SECURITIES ACT.

          PRIOR TO THE REGISTRATION OF ANY TRANSFER IN ACCORDANCE WITH (2)(D) ABOVE, THE COMPANY AND THE
TRUSTEE RESERVE THE RIGHT TO REQUIRE THE DELIVERY OF SUCH LEGAL OPINIONS, CERTIFICATIONS OR OTHER
EVIDENCE AS MAY REASONABLY BE REQUIRED IN ORDER TO DETERMINE THAT THE PROPOSED TRANSFER IS BEING
MADE IN COMPLIANCE WITH THE SECURITIES ACT AND APPLICABLE STATE SECURITIES LAWS. NO REPRESENTATION
IS MADE AS TO THE AVAILABILITY OF ANY EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE
SECURITIES ACT.

          DURING THE PERIOD ENDING ONE YEAR AFTER THE LAST DATE OF ORIGINAL ISSUANCE OF THE NOTES, NO
“AFFILIATE” (AS DEFINED IN RULE 144) WILL BE PERMITTED TO RESELL ANY OF THE NOTES THAT CONSTITUTE
“RESTRICTED SECURITIES” UNDER RULE 144 THAT HAVE BEEN REACQUIRED BY ANY OF THEM.

          No transfer of any Note prior to the Resale Restriction Termination Date will be registered by
the Note Registrar unless the applicable box on the Form of Assignment and Transfer has been
checked.

          Any Note (or security issued in exchange or substitution therefor) as to which such
restrictions on transfer shall have expired in accordance with their terms may, upon surrender of
such Note for exchange to the Note Registrar in accordance with the provisions of this Section
2.05, be exchanged for a new Note or Notes, of like tenor and aggregate principal amount, which
shall not bear the restrictive legend required by this Section 2.05(c) and shall not be assigned a
restricted CUSIP number. The Company shall be entitled to instruct the Custodian in writing to so
surrender any Global Note as to which such restrictions on transfer shall have expired in
accordance with their terms for exchange, and, upon such instruction, the Custodian shall so
surrender such Global Note for exchange; and any new Global Note so exchanged therefor shall not
bear the restrictive legend specified in this Section 2.05(c) and shall not be assigned a
restricted CUSIP number. The Company shall promptly notify the Trustee upon the occurrence of the
Resale Restriction Termination Date and promptly notify the Trustee and the Holders after

17

 

a
registration statement, if any, with respect to the Notes or any Common Stock issued upon
conversion of the Notes has been declared effective under the Securities Act.

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

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

          If (i) the Depositary notifies the Company at any time that the Depositary is unwilling or
unable to continue as depositary for the Global Notes and a successor depositary is not appointed
within 90 days, (ii) the Depositary ceases to be registered as a clearing agency under the Exchange
Act and a successor depositary is not appointed within 90 days, (iii) an Event of Default with
respect to the Notes has occurred and is continuing and a beneficial owner of any Note requests
that its beneficial interest therein be issued as a Physical Note or (iv) the Company and a
beneficial owner of any Note so agree, the Company shall execute, and the Trustee, upon receipt of
an Officer’s Certificate and a Company Order for the authentication and delivery of Notes, shall
authenticate and deliver (x) in the case of clause (iii) or (iv), a Physical Note to such
beneficial owner in a principal amount equal to the principal amount of such Note corresponding
such beneficial owner’s beneficial interest and (y) in the case of clause (i) or (ii), Physical
Notes to each beneficial owner of the related Global Notes (or a portion thereof) in an aggregate
principal amount equal to the aggregate principal amount of such Global Notes in exchange for such
Global Notes, and upon delivery of the Global Notes to the Trustee such Global Notes shall be
canceled.

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

          At such time as all interests in a Global Note have been converted, canceled, repurchased or
transferred, such Global Note shall be, upon receipt thereof, canceled by the Trustee in accordance
with its customary procedures. At any time prior to such cancellation, if any interest in a Global
Note is exchanged for Physical Notes, converted, canceled, repurchased or transferred to a
transferee who receives Physical Notes therefor or any Physical Note is exchanged or transferred
for part of such Global Note, the principal amount of such Global Note

18

 

shall, in accordance with
the Trustee’s customary procedures, be appropriately reduced or increased, as the case may be, and
an endorsement shall be made on the Schedule of Exchanges of such Global Note, by the Trustee or
the Custodian, at the direction of the Trustee, to reflect such reduction or increase.

          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 Note (including any transfers between or among Depositary
participants or beneficial owners of interests in any Global Note) 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.

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

          Neither the Company, the Trustee nor any agent of the Company or the Trustee shall have any
responsibility or liability for any aspect of the records relating to or payments made on account
of beneficial ownership interests of a Global Note or maintaining, supervising or reviewing any
records relating to such beneficial ownership interests.

          (d) Until the Resale Restriction Termination Date, any stock certificate representing Common
Stock issued upon conversion of such Note shall bear a legend in substantially the following form
(unless the Note or such Common Stock has been transferred pursuant to a registration statement
that has become or been declared effective under the Securities Act and that continues to be
effective at the time of such transfer, or pursuant to the exemption from registration provided by
Rule 144 or any similar provision then in force under the Securities Act, or such Common Stock has
been issued upon conversion of Notes that have been transferred pursuant to a registration
statement that has become or been declared effective under the Securities Act and that continues to
be effective at the time of such transfer, or pursuant to the exemption from registration provided
by Rule 144 or any similar provision then in force under the Securities Act, or unless otherwise
agreed by the Company with written notice thereof to the Trustee and any transfer agent for the
Common Stock):

          THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE
“SECURITIES ACT”), AND MAY NOT BE OFFERED, SOLD, PLEDGED OR OTHERWISE TRANSFERRED EXCEPT IN
ACCORDANCE WITH THE FOLLOWING SENTENCE. BY ITS ACQUISITION HEREOF OR OF A BENEFICIAL INTEREST
HEREIN, THE ACQUIRER:

          (1) REPRESENTS THAT IT AND ANY ACCOUNT FOR WHICH IT IS ACTING IS A “QUALIFIED
INSTITUTIONAL BUYER” (WITHIN THE MEANING OF RULE 144A UNDER THE SECURITIES ACT) AND THAT IT
EXERCISES SOLE INVESTMENT DISCRETION WITH RESPECT TO EACH SUCH ACCOUNT, AND

19

 

          (2) AGREES FOR THE BENEFIT OF INTEGRA LIFESCIENCES HOLDINGS CORPORATION (THE “COMPANY”)
THAT IT WILL NOT OFFER, SELL, PLEDGE OR OTHERWISE TRANSFER THIS SECURITY OR ANY BENEFICIAL
INTEREST HEREIN PRIOR TO THE DATE THAT IS THE LATER OF (X) ONE YEAR AFTER THE LAST ORIGINAL
ISSUE DATE HEREOF OR SUCH SHORTER PERIOD OF TIME AS PERMITTED BY RULE 144 UNDER THE
SECURITIES ACT OR ANY SUCCESSOR PROVISION THERETO AND (Y) SUCH LATER DATE, IF ANY, AS MAY BE
REQUIRED BY APPLICABLE LAW, EXCEPT:

          (A) TO THE COMPANY OR ANY SUBSIDIARY THEREOF, OR

          (B) PURSUANT TO A REGISTRATION STATEMENT WHICH HAS BECOME EFFECTIVE UNDER THE
SECURITIES ACT, OR

          (C) TO A QUALIFIED INSTITUTIONAL BUYER IN COMPLIANCE WITH RULE 144A UNDER THE
SECURITIES ACT, OR

          (D) PURSUANT TO AN EXEMPTION FROM REGISTRATION PROVIDED BY RULE 144 UNDER THE
SECURITIES ACT OR ANY OTHER AVAILABLE EXEMPTION FROM THE REGISTRATION REQUIREMENTS
OF THE SECURITIES ACT.

          PRIOR TO THE REGISTRATION OF ANY TRANSFER IN ACCORDANCE WITH (2)(D) ABOVE, THE COMPANY AND THE
TRUSTEE RESERVE THE RIGHT TO REQUIRE THE DELIVERY OF SUCH LEGAL OPINIONS, CERTIFICATIONS OR OTHER
EVIDENCE AS MAY REASONABLY BE REQUIRED IN ORDER TO DETERMINE THAT THE PROPOSED TRANSFER IS BEING
MADE IN COMPLIANCE WITH THE SECURITIES ACT AND APPLICABLE STATE SECURITIES LAWS. NO REPRESENTATION
IS MADE AS TO THE AVAILABILITY OF ANY EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE
SECURITIES ACT.

          Any such Common Stock as to which such restrictions on transfer shall have expired in
accordance with their terms may, upon surrender of the certificates representing such shares of
Common Stock for exchange in accordance with the procedures of the transfer agent for the Common
Stock, be exchanged for a new certificate or certificates for a like aggregate number of shares of
Common Stock, which shall not bear the restrictive legend required by this Section 2.05(d).

          (e) The Company shall not, and shall not permit any of its “affiliates” (as defined in Rule
144) to, resell any of the Notes that constitute “restricted securities” under Rule 144 that have
been reacquired by any of them.

          Section 2.06. Mutilated, Destroyed, Lost or Stolen Notes. In case any Note shall become
mutilated or be destroyed, lost or stolen, the Company in its discretion may execute, and upon its
written request in a Company Order the Trustee or an authenticating agent appointed by the Trustee
shall authenticate and deliver, a new Note, bearing a registration number not contemporaneously
outstanding, in exchange and substitution for the mutilated Note, or in lieu of

20

 

and in substitution
for the Note so destroyed, lost or stolen. In every case the applicant for a substituted Note
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 from any loss,
liability, cost or expense caused by or connected with such substitution, and, in every case of
destruction, loss or theft, the applicant shall also furnish to the Company, to the Trustee and, if
applicable, to such authenticating agent evidence to their satisfaction of the destruction, loss or
theft of such Note and of the ownership thereof.

          The Trustee or such authenticating agent may authenticate any such substituted Note and
deliver the same upon the receipt of such security or indemnity as the Trustee, the Company and, if
applicable, such authenticating agent may require. Upon the issuance of any substitute Note, the
Company or the Trustee may require the payment by the Holder of a sum sufficient to cover any tax,
assessment or other governmental charge that may be imposed in relation thereto and any other
expenses connected therewith. In case any Note that has matured or is about to mature or has been
surrendered for required repurchase or is about to be converted in accordance with Article 14 shall
become mutilated or be destroyed, lost or stolen, the Company may, in its sole discretion, instead
of issuing a substitute Note, 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 Note), 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 connected with such substitution, and, in every case of destruction, loss or theft, evidence
satisfactory to the Company, the Trustee and, if applicable, any Paying Agent or Conversion Agent
of the destruction, loss or theft of such Note and of the ownership thereof.

          Every substitute Note issued pursuant to the provisions of this Section 2.06 by virtue of the
fact that any Note is destroyed, lost or stolen shall constitute an additional contractual
obligation of the Company, whether or not the destroyed, lost or stolen Note shall be found at any
time, and shall be entitled to all the benefits of (but shall be subject to all the limitations set
forth in) this Indenture equally and proportionately with any and all other Notes duly issued
hereunder. To the extent permitted by law, all Notes shall be held and owned upon the express
condition that the foregoing provisions are exclusive with respect to the replacement or payment or
conversion or repurchase of mutilated, destroyed, lost or stolen Notes and shall preclude any and
all other rights or remedies notwithstanding any law or statute existing or hereafter enacted to
the contrary with respect to the replacement or payment or conversion of negotiable instruments or
other securities without their surrender.

          Section 2.07. Temporary Notes. Pending the preparation of Physical Notes, the Company may
execute and the Trustee or an authenticating agent appointed by the Trustee shall, upon written
request of the Company in a Company Order, authenticate and deliver temporary Notes (printed or
lithographed). Temporary Notes shall be issuable in any authorized denomination, and substantially
in the form of the Physical Notes but with such omissions, insertions and variations as may be
appropriate for temporary Notes, all as may be determined by the Company. Every such temporary
Note 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
Physical Notes. Without unreasonable delay, the Company shall execute and deliver to the Trustee
or such authenticating agent Physical Notes

21

 

(other than any Global Note) and thereupon any or all
temporary Notes (other than any Global Note) may be surrendered in exchange therefor, at each
office or agency maintained by the Company pursuant to Section 4.02 and the Trustee or such
authenticating agent shall authenticate and deliver in exchange for such temporary Notes an equal
aggregate principal amount of Physical Notes. Such exchange shall be made by the Company at its
own expense and without any charge therefor. Until so exchanged, the temporary Notes shall in all
respects be entitled to the same benefits and subject to the same limitations under this Indenture
as Physical Notes authenticated and delivered hereunder.

          Section 2.08. Cancellation of Notes Paid, Converted, Etc. The Company shall cause all Notes
surrendered for the purpose of payment, repurchase, registration of transfer or exchange or
conversion, if surrendered to the Company or the Company’s Agents, Subsidiaries or Affiliates, to
be surrendered to the Trustee for cancellation. All Notes delivered to the Trustee shall be
canceled promptly by it, and no Notes shall be authenticated in exchange thereof except as
expressly permitted by any of the provisions of this Indenture. The Trustee shall dispose of
canceled Notes in accordance with its customary procedures and, after such disposition, shall
deliver a certificate of such disposition to the Company, at the Company’s written request in a
Company Order. If the Company shall acquire any of the Notes, such acquisition shall not operate
as a redemption, repurchase or satisfaction of the indebtedness represented by such Notes unless
and until the same are delivered to the Trustee for cancellation.

          Section 2.09. CUSIP Numbers. The Company in issuing the Notes may use “CUSIP” numbers (if
then generally in use), and, if so, the Trustee shall use “CUSIP” numbers in all notices issued to
Holders as a convenience to such Holders; provided that any such notice may state that no
representation is made as to the correctness of such numbers either as printed on the Notes or on
such notice and that reliance may be placed only on the other identification numbers printed on the
Notes. The Company shall promptly notify the Trustee in writing of any change in the “CUSIP”
numbers.

          Section 2.10. Additional Notes; Repurchases. The Company may, without the consent of the
Holders and notwithstanding Section 2.01, reopen this Indenture and issue additional Notes
hereunder with the same terms and with the same CUSIP number as the Notes initially issued
hereunder in an unlimited aggregate principal amount; provided that if any such additional Notes
are not fungible with the Notes initially issued hereunder for U.S. federal income tax purposes,
such additional Notes shall have a separate CUSIP number. Prior to the issuance of any such
additional Notes, the Company shall deliver to the Trustee a Company Order, an Officer’s
Certificate and an Opinion of Counsel, such Officer’s Certificate and Opinion of Counsel to cover
such matters required by Section 17.05, and such Opinion of Counsel to include a customary legal
opinion as to the enforceability under New York law of such additional Notes, which opinion may
contain customary exceptions and qualifications. In addition, the Company may, to the extent
permitted by law, and directly or indirectly (regardless of whether such Notes are surrendered to
the Company), repurchase Notes in the open market or otherwise, whether by the Company or its
Subsidiaries or through a private or public tender or exchange offer or through counterparties to
private agreements, including by cash-settled swaps or other derivatives. The Company shall cause
any Notes so repurchased (other than Notes repurchased pursuant to cash-settled swaps or other
derivatives) to be surrendered to the Trustee for cancellation in accordance with Section 2.08.

22

 

ARTICLE 3

Satisfaction and Discharge

          Section 3.01. Satisfaction and Discharge. This Indenture shall upon request of the Company
contained in an Officer’s Certificate cease to be of further effect, and the Trustee, at the
expense of the Company, shall execute proper instruments acknowledging satisfaction and discharge
of this Indenture, when (a) (i) all Notes theretofore authenticated and delivered (other than (x)
Notes which have been destroyed, lost or stolen and which have been replaced or paid as provided in
Section 2.06 and (y) Notes for whose payment money has theretofore been deposited in trust or
segregated and held in trust by the Company and thereafter repaid to the Company or discharged from
such trust, as provided in Section 4.04(d)) have been delivered to the Trustee for cancellation; or
(ii) the Company has deposited with the Trustee or delivered to Holders, as applicable, after the
Notes have become due and payable, whether at the Maturity Date, any Fundamental Change Repurchase
Date, upon conversion or otherwise, cash or cash and shares of Common Stock, if any (solely to
satisfy the Company’s Conversion Obligation, if applicable), sufficient to pay all of the
outstanding Notes and all other sums due and payable under this Indenture by the Company; and (b)
the Company has delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel, each
stating that all conditions precedent herein provided for relating to the satisfaction and
discharge of this Indenture have been complied with. Notwithstanding the satisfaction and
discharge of this Indenture, the obligations of the Company to the Trustee under Section 7.06 shall
survive.

ARTICLE 4

Particular Covenants of the Company

          Section 4.01. Payment of Principal and Interest. The Company covenants and agrees that it
will cause to be paid the principal (including the Fundamental Change Repurchase Price, if
applicable) of, and accrued and unpaid interest on, each of the Notes at the places, at the
respective times and in the manner provided herein and in the Notes.

          Section 4.02. Maintenance of Office or Agency. The Company will maintain in the Borough of
Manhattan, The City of New York, an office or agency where the Notes may be surrendered for
registration of transfer or exchange or for presentation for payment or repurchase (“Paying Agent”)
or for conversion (“Conversion Agent”) and where notices and demands to or upon the Company in
respect of the Notes and this Indenture may be served. The Company will give prompt written notice
to the Trustee of the location, and any change in the location, of such office or agency. If at
any time the Company shall fail to maintain any such required office or agency or shall fail to
furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands
may be made or served at the Corporate Trust Office or the office or agency of the Trustee in the
Borough of Manhattan, The City of New York.

          The Company may also from time to time designate as co-Note Registrars one or more other
offices or agencies where the Notes may be presented or surrendered for any or all such purposes
and may from time to time rescind such designations; provided that no such designation or
rescission shall in any manner relieve the Company of its obligation to maintain an office or
agency in the Borough of Manhattan, The City of New York, for such purposes. The Company

23

 

will give
prompt written notice to the Trustee of any such designation or rescission and of any change in the
location of any such other office or agency. The terms “Paying Agent” and “Conversion Agent”
include any such additional or other offices or agencies, as applicable.

          The Company hereby initially designates the Trustee as the Paying Agent, Note Registrar,
Custodian and Conversion Agent and the Corporate Trust Office and the office or agency of the
Trustee in the Borough of Manhattan, The City of New York, each shall be considered as one such
office or agency of the Company for each of the aforesaid purposes.

          Section 4.03. Appointments to Fill Vacancies in Trustee’s Office. The Company, whenever
necessary to avoid or fill a vacancy in the office of Trustee, will appoint, in the manner provided
in Section 7.09, a Trustee, so that there shall at all times be a Trustee hereunder.

          Section 4.04. Provisions as to Paying Agent. (a) If the Company shall appoint a Paying Agent
other than the Trustee, 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 4.04:

          (i) that it will hold all sums held by it as such agent for the payment of the
principal (including the Fundamental Change Repurchase Price, if applicable) of, and accrued
and unpaid interest on, the Notes in trust for the benefit of the Holders of the Notes;

          (ii) that it will give the Trustee prompt written notice of any failure by the Company
to make any payment of the principal (including the Fundamental Change Repurchase Price, if
applicable) of, and accrued and unpaid interest on, the Notes 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 (including the Fundamental
Change Repurchase Price, if applicable) of, or accrued and unpaid interest on, the Notes, deposit
with the Paying Agent a sum sufficient to pay such principal (including the Fundamental Change
Repurchase Price, if applicable) or accrued and unpaid interest, and (unless such Paying Agent is
the Trustee) the Company will promptly notify the Trustee in writing of any failure to take such
action; provided that if such deposit is made on the due date, such deposit must be received by the
Paying Agent by 11:00 a.m., New York City time, on such date.

          (b) If the Company shall act as its own Paying Agent, it will, on or before each due date of
the principal (including the Fundamental Change Repurchase Price, if applicable) of, and accrued
and unpaid interest on, the Notes, set aside, segregate and hold in trust for the benefit of the
Holders of the Notes a sum sufficient to pay such principal (including the Fundamental Change
Repurchase Price, if applicable) and accrued and unpaid interest so becoming due and will promptly
notify the Trustee in writing of any failure to take such action and of any failure by the Company
to make any payment of the principal (including the Fundamental Change

24

 

Repurchase Price, if
applicable) of, or accrued and unpaid interest on, the Notes when the same shall become due and
payable.

          (c) Anything in this Section 4.04 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, cause to be paid or deliver to the Trustee all sums or amounts held in trust by the
Company or any Paying Agent hereunder as required by this Section 4.04, such sums or amounts to be
held by the Trustee upon the trusts herein contained and upon such payment or delivery by the
Company or any Paying Agent to the Trustee, the Company or such Paying Agent shall be released from
all further liability but only with respect to such sums or amounts.

          (d) Any money and shares of Common Stock deposited with the Trustee or any Paying Agent, or
then held by the Company, in trust for the payment of the principal (including the Fundamental
Change Repurchase Price, if applicable) of, and accrued and unpaid interest on, any Note and
remaining unclaimed for two years after such principal (including the Fundamental Change Repurchase
Price, if applicable) or interest has become due and payable shall be paid to the Company on
request of the Company contained in an Officer’s Certificate, or (if then held by the Company)
shall be discharged from such trust; and the Holder of such Note shall thereafter, as an unsecured
general creditor, look only to the Company for payment thereof, and all liability of the Trustee or
such Paying Agent with respect to such trust money and shares of Common Stock, and all liability of
the Company as trustee thereof, shall thereupon cease.

          Section 4.05. Existence. Subject to Article 11, the Company shall do or cause to be done all
things necessary to preserve and keep in full force and effect its corporate existence.

          Section 4.06. Rule 144A Information Requirement and Annual Reports. (a) At any time the
Company is not subject to Sections 13 or 15(d) of the Exchange Act, the Company shall, so long as
any of the Notes shall, at such time, constitute “restricted securities” within the meaning of Rule
144(a)(3) under the Securities Act, promptly provide to the Trustee and shall, upon written
request, provide to any Holder, beneficial owner or prospective purchaser of such Notes, the
information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act to
facilitate the resale of such Notes pursuant to Rule 144A under the Securities Act. The Company
shall take such further action as any Holder or beneficial owner of such Notes may reasonably
request to the extent required from time to time to enable such Holder or beneficial owner to sell
such Notes in accordance with Rule 144A under the Securities Act, as such rule may be amended from
time to time.

          (b) The Company shall file with the Trustee within 15 days after the same are required to be
filed with the Commission, copies of any documents or reports that the Company is required to file
with the Commission pursuant to Section 13 or 15(d) of the Exchange Act (giving effect to any grace
period provided by Rule 12b-25 under the Exchange Act or any successor or similar grace provision).
Any such document or report that the Company files with the Commission via the Commission’s EDGAR
system shall be deemed to be filed with the Trustee for purposes of this Section 4.06(b) at the
time such documents are filed via the EDGAR system, it being understood that the Trustee shall not
be responsible for determining whether such filings have been made.

25

 

          (c) Delivery of the reports and documents described in subsection (b) above 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 on an Officer’s Certificate).

          (d) If, at any time during the six-month period beginning on, and including, the date that is
six months after the last date of original issuance of the Notes, the Company fails to timely file
any document or report that it is required to file with the Commission pursuant to Section 13 or
15(d) of the Exchange Act, as applicable (after giving effect to all applicable grace periods
thereunder and other than reports on Form 8-K), or the Notes are not otherwise freely tradable by
Holders other than the Company’s Affiliates (as a result of restrictions pursuant to U.S.
securities law or the terms of this Indenture or the Notes), the Company shall pay Additional
Interest on the Notes. Such Additional Interest shall accrue on the Notes at the rate of 0.50% per
annum of the principal amount of the Notes outstanding for each day during such period for which
the Company’s failure to file has occurred and is continuing. As used in this Section 4.06(d),
documents or reports that the Company is required to “file” with the Commission pursuant to Section
13 or 15(d) of the Exchange Act do not include documents or reports that the Company furnishes to
the Commission pursuant to Section 13 or 15(d) of the Exchange Act.

          (e) If, and for so long as, the restrictive legend on the Notes specified in Section 2.05(c)
has not been removed, the Notes are assigned a restricted CUSIP number or the Notes are not
otherwise freely tradable by Holders other than the Company’s Affiliates (without restrictions
pursuant to U.S. securities law or the terms of this Indenture or the Notes) as of the 375th day
after the last date of original issuance of the Notes, the Company shall pay Additional Interest on
the Notes at a rate equal to 0.50% per annum of the principal amount of Notes outstanding until the
restrictive legend on the Notes has been removed in accordance with Section 2.05(c) and the Notes
are freely tradable by Holders other than the Company’s Affiliates (without restrictions pursuant
to U.S. securities law or the terms of this Indenture or the Notes); provided that the Company
shall not pay Additional Interest on the Notes for failure to remove the restrictive legend on the
Notes specified in Section 2.05(c) or failure to cause the Notes to be assigned an unrestricted
CUSIP number unless the Company has received a request to remove such legend and obtain an
unrestricted CUSIP number by a Holder, any Initial Purchaser or the Trustee on or after the 335th
day after the last date of original issuance of the Notes. Additional Interest will accrue from (i)
if such request has been delivered prior to the 365th day after the last date of original issuance
of the Notes, the 375th day after such last date of original issuance of the Notes or (ii)
otherwise, ten days from the delivery date of such request

          (f) Notwithstanding the foregoing, no Additional Interest will accrue or be payable under
Section 4.06(e) for each day on which (i) the Company makes available to Holders an effective
registration statement permitting the resale of the Notes and any shares of Common Stock issuable
upon conversion thereof and (ii) the Notes sold under such registration statement and any shares of
Common Stock issuable upon conversion thereof are assigned an unrestricted CUSIP number and are
freely tradable by Holders other than the Company’s Affiliates (without restrictions pursuant to
U.S. securities law or the terms of this Indenture or the Notes). After the Company has made
available such an effective shelf registration statement and has complied

26

 

with clause (ii) above
for a period of at least two years, no further Additional Interest shall be payable under Section
4.06(e).

          (g) Additional Interest will be payable in arrears on each Interest Payment Date following
accrual in the same manner as regular interest on the Notes.

          (h) The Additional Interest that is payable in accordance with Section 4.06(d) or Section
4.06(e) shall be in addition to, and not in lieu of, any Additional Interest that may be payable as
a result of the Company’s election pursuant to Section 6.03. Notwithstanding the foregoing, in no
event shall Additional Interest accrue under the terms of this Indenture (taking any Additional
Interest payable pursuant to Section 4.06(d) or Section 4.06(e) together with any Additional
Interest payable pursuant to Section 6.03) at a rate per year in excess of 0.50%, regardless of the
number of events or circumstances giving rise to the requirement to pay such Additional Interest.

          (i) If Additional Interest is payable by the Company pursuant to Section 4.06(d) or Section
4.06(e), the Company shall deliver to the Trustee an Officer’s Certificate to that effect stating
(i) the amount of such Additional Interest that is payable and (ii) the date on which such
Additional Interest is payable. Unless and until a Responsible Officer of the Trustee receives at
the Corporate Trust Office such a certificate, the Trustee may assume without inquiry that no such
Additional Interest is payable. If the Company has paid Additional Interest directly to the
Persons entitled to it, the Company shall deliver to the Trustee an Officer’s Certificate setting
forth the particulars of such payment.

          Section 4.07. Stay, Extension and Usury Laws. The Company covenants (to the extent that it
may lawfully do so) that it shall not at any time insist upon, plead, or in any manner whatsoever
claim or take the benefit or advantage of, any stay, extension or usury law or other law that would
prohibit or forgive the Company from paying all or any portion of the principal of or interest on
the Notes as contemplated herein, wherever enacted, now or at any time hereafter in force, or that
may affect the covenants or the performance of this Indenture; and the Company (to the extent it
may lawfully do so) hereby expressly waives all benefit or advantage of any such law, and covenants
that it will not, by resort to any such law, hinder, delay or impede the execution of any power
herein granted to the Trustee, but will suffer and permit the execution of every such power as
though no such law had been enacted.

          Section 4.08. Compliance Certificate; Statements as to Defaults. The Company shall deliver
to the Trustee within 120 days after the end of each fiscal year of the Company (beginning with the
fiscal year ending on December 31, 2011) an Officer’s Certificate stating whether or not the
signers thereof have knowledge of any failure by the Company to comply with all conditions and
covenants then required to be performed under this Indenture and, if so, specifying each such
failure and the nature thereof.

          In addition, the Company shall deliver to the Trustee, as soon as possible, and in any event
within 30 days after the Company becomes aware of the occurrence of any Event of Default or
Default, an Officer’s Certificate setting forth the details of such Event of Default or Default,
its status and the action that the Company proposes to take with respect thereto.

27

 

          Section 4.09. Further Instruments and Acts. Upon request of the Trustee, the Company will
execute and deliver such further instruments and do such further acts as may be reasonably
necessary or proper to carry out more effectively the purposes of this Indenture.

ARTICLE 5

Lists of Holders and Reports by the Company and the Trustee

          Section 5.01. Lists of Holders. For so long as there are any Physical Notes, the Company
covenants and agrees that it will furnish or cause to be furnished to the Trustee, semi-annually,
not more than 15 days after each June 1 and December 1 in each year beginning with December 1,
2011, and at such other times as the Trustee may request in writing, within 30 days after receipt
by the Company of any such request (or such lesser time as the Trustee may reasonably request in
order to enable it to timely provide any notice to be provided by it hereunder), a list in such
form as the Trustee may reasonably require of the names and addresses of the Holders as of a date
not more than 15 days (or such other date as the Trustee may reasonably request in order to so
provide any such notices) prior to the time such information is furnished, except that no such list
need be furnished so long as the Trustee is acting as Note Registrar.

          Section 5.02. Preservation and Disclosure of Lists. The Trustee shall preserve, in as
current a form as is reasonably practicable, all information as to the names and addresses of the
Holders contained in the most recent list furnished to it as provided in Section 5.01 or maintained
by the Trustee in its capacity as Note Registrar, if so acting. The Trustee may destroy any list
furnished to it as provided in Section 5.01 upon receipt of a new list so furnished.

ARTICLE 6

Defaults and Remedies

          Section 6.01. Events of Default. The following events shall be “Events of Default” with
respect to the Notes:

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

          (b) default in the payment of principal (including the Fundamental Change Repurchase Price, if
applicable) of any Note when due and payable on the Maturity Date, upon any required repurchase,
upon declaration of acceleration or otherwise;

          (c) failure by the Company to comply with its obligation to convert the Notes in accordance
with this Indenture upon exercise of a Holder’s conversion right, and such failure continues for a
period of 5 Business Days;

          (d) failure by the Company to issue a Fundamental Change Company Notice in accordance with
Section 15.02(c) or notice of a specified corporate event in accordance with Section 14.01(b)(ii)
or Section 14.01(b)(iii), in each case when due;

28

 

          (e) failure by the Company to comply with its obligations under Article 11;

          (f) failure by the Company for 60 days after written notice from the Trustee or the Holders of
at least 25% in principal amount of the Notes then outstanding has been received by the Company to
comply with any of its other agreements contained in the Notes or this Indenture;

          (g) default by the Company or any Subsidiary of the Company in the payment when due, after the
expiration of any applicable grace period, of principal of, or premium, if any, or interest on,
recourse indebtedness for money borrowed in the aggregate principal amount then outstanding of
$25.0 million or more, or acceleration of the Company’s or the Company’s Subsidiaries’ recourse
indebtedness for money borrowed in the aggregate principal amount of $25.0 million or more so that
it becomes due and payable before the date on which it would otherwise have become due and payable,
if such default is not cured or waived, or such acceleration is not rescinded, as the case may be,
within 30 days after written notice to the Company from the Trustee or the Holders of at least 25%
in principal amount of Notes then outstanding in accordance with this Indenture;

          (h) a final judgment for the payment of $25.0 million or more (excluding any amounts covered
by insurance) rendered against the Company or any Subsidiary of the Company, which judgment is not
discharged 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;

          (i) the Company or any Significant Subsidiary shall commence a voluntary case or other
proceeding seeking liquidation, reorganization or other relief with respect to the Company or any
such Significant Subsidiary or its debts under any bankruptcy, insolvency or other similar law now
or hereafter in effect or seeking the appointment of a trustee, receiver, liquidator, custodian or
other similar official of the Company or any such Significant Subsidiary or any substantial part of
its property, or shall consent to any such relief or to the appointment of or taking possession by
any such official in an involuntary case or other proceeding commenced against it, or shall make a
general assignment for the benefit of creditors, or shall fail generally to pay its debts as they
become due; or

          (j) an involuntary case or other proceeding shall be commenced against the Company or any
Significant Subsidiary seeking liquidation, reorganization or other relief with respect to the
Company or such Significant Subsidiary or its debts under any bankruptcy, insolvency or other
similar law now or hereafter in effect or seeking the appointment of a trustee, receiver,
liquidator, custodian or other similar official of the Company or such Significant Subsidiary or
any substantial part of its property, and such involuntary case or other proceeding shall remain
undismissed and unstayed for a period of 30 consecutive days.

          Section 6.02. Acceleration; Rescission and Annulment. In case one or more Events of Default
shall have occurred and be continuing (whatever the reason for such Event of Default and whether it
shall be voluntary or involuntary or be 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), then, and in each and every such case (other than an Event of Default specified in Section
6.01(i) or Section 6.01(j) with respect to the Company or any of its

29

 

Significant Subsidiaries),
unless the principal of all of the Notes shall have already become due and payable, either the
Trustee or the Holders of at least 25% in aggregate principal amount of the Notes then outstanding
determined in accordance with Section 8.04, by notice in writing to the Company (and to the Trustee
if given by Holders), may declare 100% of the principal of, and accrued and unpaid interest on, all
the Notes to be due and payable immediately, and upon any such declaration the same shall become
and shall automatically be immediately due and payable, anything contained in this Indenture or in
the Notes to the contrary notwithstanding. If an Event of Default specified in Section 6.01(i) or
Section 6.01(j) with respect to the Company or any of its Significant Subsidiaries occurs and is
continuing, 100% of the principal of, and accrued and unpaid interest, if any, on, all Notes shall
become and shall automatically be immediately due and payable.

          The immediately preceding paragraph, however, is subject to the conditions that if, at any
time after the principal of the Notes shall have been so declared due and payable, and before any
judgment or decree for the payment of the monies due shall have been obtained or entered as
hereinafter provided, the Company shall pay or shall deposit with the Trustee a sum sufficient to
pay installments of accrued and unpaid interest upon all Notes and the principal of any and all
Notes that shall have become due otherwise than by acceleration (with interest on overdue
installments of accrued and unpaid interest to the extent that payment of such interest is
enforceable under applicable law, and on such principal at the rate borne by the Notes) and amounts
due to the Trustee pursuant to Section 7.06, and if (1) rescission would not conflict with any
judgment or decree of a court of competent jurisdiction and (2) any and all existing Events of
Default under this Indenture, other than the nonpayment of the principal of and accrued and unpaid
interest, if any, on Notes that shall have become due solely by such acceleration, shall have been
cured or waived pursuant to Section 6.09, then and in every such case (except as provided in the
immediately succeeding sentence) the Holders of a majority in aggregate principal amount of the
Notes then outstanding, by written notice to the Company and to the Trustee, may waive all Defaults
or Events of Default with respect to the Notes and rescind and annul such declaration and its
consequences and 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 or
rescission and annulment shall extend to or shall affect any subsequent Default or Event of
Default, or shall impair any right consequent thereon. Notwithstanding anything to the contrary
herein, no such waiver or rescission and annulment shall extend to or shall affect any Default or
Event of Default resulting from (i) the nonpayment of the principal of, or accrued and unpaid
interest on, any Notes or (ii) a failure to pay or deliver, as the case may be, the consideration
due upon conversion of the Notes.

          Section 6.03. Additional Interest. Notwithstanding anything in this Indenture or in the
Notes to the contrary, to the extent the Company elects, the sole remedy for Event of Default
relating to the Company’s failure to comply with its obligations as set forth in Section 4.06(b)
shall after the occurrence of such an Event of Default consist exclusively of the right to receive
Additional Interest on the Notes at a rate equal to (x) 0.25% per annum of the principal amount of
the Notes outstanding for each day during the 90-day period on which such Event of Default is
continuing beginning on, and including, the date on which such an Event of Default first occurs and
(y) 0.50% per annum of the principal amount of the Notes outstanding for each day during the
180-day period beginning on, and including, the 91st day on which such Event of

30

 

Default is
continuing. Additional Interest payable pursuant to this Section 6.03 shall be in addition to, not
in lieu of, any Additional Interest payable pursuant to Section 4.06(d) or Section 4.06(e). If the
Company so elects, such Additional Interest shall be payable in the same manner and on the same
dates as regular interest on the Notes. On the 271st day after such Event of Default (if the Event
of Default relating to the Company’s failure to comply with its obligations as set forth in Section
4.06(b) is not cured or waived prior to such 271st day), the Notes will be subject to acceleration
as provided in Section 6.02. In the event the Company does not elect to pay Additional Interest
following an Event of Default in accordance with this Section 6.03, the Notes shall be subject to
acceleration as provided in Section 6.02.

          In order to elect to pay Additional Interest as the sole remedy during the first 270 days
after the occurrence of any Event of Default described in the immediately preceding paragraph, the
Company must notify in writing all Holders of the Notes, the Trustee and the Paying Agent of such
election prior to the beginning of such 270-day period. Upon the failure to timely give such
notice, the Notes shall be immediately subject to acceleration as provided in Section 6.02.

          In no event shall Additional Interest accrue under the terms of this Indenture (taking any
Additional Interest payable pursuant to this Section 6.03 together with any Additional Interest
payable pursuant to Section 4.06(d) or Section 4.06(e)) at a rate per year in excess of 0.50%,
regardless of the number of events or circumstances giving rise to the requirement to pay such
Additional Interest.

          The Trustee shall not at any time be under any duty or responsibility to any Holder to
determine Additional Interest, or with respect to the nature, extent or calculation of the amount
of Additional Interest owed, or with respect to the method employed in such calculation of
Additional Interest.

          Section 6.04. Payments of Notes on Default; Suit Therefor. If an Event of Default described
in clause (a) or (b) of Section 6.01 shall have occurred, the Company shall, upon demand of the
Trustee, pay to the Trustee, for the benefit of the Holders of the Notes, the whole amount then due
and payable on the Notes for principal and interest, if any, with interest on any overdue principal
and interest, if any, at the rate borne by the Notes at such time, and, in addition thereto, such
further amount as shall be sufficient to cover any amounts due to the Trustee under Section 7.06.
If the Company shall fail to pay such amounts forthwith upon such demand, the Trustee, in its own
name and as trustee of an express trust, may institute a judicial proceeding for the collection of
the sums so due and unpaid, may prosecute such proceeding to judgment or final decree and may
enforce the same against the Company or any other obligor upon the Notes and collect the moneys
adjudged or decreed to be payable in the manner provided by law out of the property of the Company
or any other obligor upon the Notes, wherever situated.

          In the event there shall be pending proceedings for the bankruptcy or for the reorganization
of the Company or any other obligor on the Notes under title 11 of the United States Code, or any
other applicable law, or in case a receiver, assignee or trustee in bankruptcy or reorganization,
liquidator, sequestrator or similar official shall have been appointed for or taken possession of
the Company or such other obligor, the property of the Company or such other obligor, or in the
event of any other judicial proceedings relative to the Company or such other obligor upon the
Notes, or to the creditors or property of the Company or such other

31

 

obligor, the Trustee,
irrespective of whether the principal of the Notes shall then be due and payable as therein
expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made
any demand pursuant to the provisions of this Section 6.04, shall be entitled and empowered, by
intervention in such proceedings or otherwise, to file and prove a claim or claims for the whole
amount of principal and accrued and unpaid interest, if any, in respect of the Notes, and, in case
of any judicial proceedings, to file such proofs of claim and other papers or documents and to take
such other actions as it may deem necessary or advisable in order to have the claims of the Trustee
(including any claim for the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel) and of the Holders allowed in such judicial proceedings relative
to the Company or any other obligor on the Notes, its or their creditors, or its or their property,
and to collect and receive any monies or other property payable or deliverable on any such claims,
and to distribute the same after the deduction of any amounts due to the Trustee under Section
7.06; and any receiver, assignee or trustee in bankruptcy or reorganization, liquidator, custodian
or similar official is hereby authorized by each of the Holders to make such payments to the
Trustee, as administrative expenses, 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 reasonable
compensation, expenses, advances and disbursements, including agents and counsel fees, and
including any other amounts due to the Trustee under Section 7.06, incurred by it up to the date of
such distribution. To the extent that such payment of reasonable compensation, expenses, advances
and disbursements out of the estate in any such proceedings shall be denied for any reason, payment
of the same shall be secured by a lien on, and shall be paid out of, any and all distributions,
dividends, monies, securities and other property that the Holders of the Notes may be entitled to
receive in such proceedings, whether in liquidation or under any plan of reorganization or
arrangement or otherwise.

          Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to
or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or
composition affecting such Holder 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.

          All rights of action and of asserting claims under this Indenture, or under any of the Notes,
may be enforced by the Trustee without the possession of any of the Notes, or the production
thereof at any trial or other proceeding relative thereto, and any such suit or proceeding
instituted by the Trustee shall be brought in its own name as trustee of an express trust, and any
recovery of judgment shall, after provision for the payment of the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable
benefit of the Holders of the Notes.

          In any proceedings brought by the Trustee (and in any proceedings involving the interpretation
of any provision of this Indenture to which the Trustee shall be a party) the Trustee shall be held
to represent all the Holders of the Notes, and it shall not be necessary to make any Holders of the
Notes parties to any such proceedings.

          In case the Trustee shall have proceeded to enforce any right under this Indenture and such
proceedings shall have been discontinued or abandoned because of any waiver pursuant to Section
6.09 or any rescission and annulment pursuant to Section 6.02 or for any other reason or

32

 

shall have
been determined adversely to the Trustee, then and in every such case the Company, the Holders, and
the Trustee shall, subject to any determination in such proceeding, be restored respectively to
their several positions and rights hereunder, and all rights, remedies and powers of the Company,
the Holders, and the Trustee shall continue as though no such proceeding had been instituted.

          Section 6.05. Application of Monies Collected by Trustee. Any monies collected by the
Trustee pursuant to this Article 6 with respect to the Notes shall be applied in the order
following, at the date or dates fixed by the Trustee for the distribution of such monies, upon
presentation of the several Notes, and stamping thereon 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 7.06;

          Second, in case the principal of the outstanding Notes shall not have become due and be
unpaid, to the payment of interest on, and any cash due upon conversion of, the Notes in default in
the order of the date due of the payments of such interest and cash due upon conversion, as the
case may be, with interest (to the extent that such interest has been collected by the Trustee)
upon such overdue payments at the rate borne by the Notes at such time, such payments to be made
ratably to the Persons entitled thereto;

          Third, in case the principal of the outstanding Notes shall have become due, by declaration or
otherwise, and be unpaid to the payment of the whole amount (including, if applicable, the payment
of the Fundamental Change Repurchase Price and any cash due upon conversion) then owing and unpaid
upon the Notes for principal and interest, if any, with interest on the overdue principal and, to
the extent that such interest has been collected by the Trustee, upon overdue installments of
interest at the rate borne by the Notes at such time, and in case such monies shall be insufficient
to pay in full the whole amounts so due and unpaid upon the Notes, then to the payment of such
principal (including, if applicable, the Fundamental Change Repurchase Price and the cash due upon
conversion) and interest without preference or priority of principal over interest, or of interest
over principal or of any installment of interest over any other installment of interest, or of any
Note over any other Note, ratably to the aggregate of such principal (including, if applicable, the
Fundamental Change Repurchase Price and any cash due upon conversion) and accrued and unpaid
interest; and

          Fourth, to the payment of the remainder, if any, to the Company.

          Section 6.06. Proceedings by Holders. Except to enforce the right to receive payment of
principal (including, if applicable, the Fundamental Change Repurchase Price) or interest when due,
or the right to receive payment or delivery of the consideration due upon conversion, no Holder of
any Note shall have any right by virtue of or by availing of any provision of this Indenture to
institute any suit, action or proceeding in equity or at law upon or under or with respect to this
Indenture, or for the appointment of a receiver, trustee, liquidator, custodian or other similar
official, or for any other remedy hereunder, unless:

          (a) such Holder previously shall have given to the Trustee written notice of an Event of
Default and of the continuance thereof, as herein provided;

33

 

          (b) Holders of at least 25% in aggregate principal amount of the Notes then outstanding shall
have made written request upon the Trustee to institute such action, suit or proceeding in its own
name as Trustee hereunder;

          (c) such Holders shall have offered to the Trustee such security or indemnity satisfactory to
it against any loss, liability or expense to be incurred therein or thereby;

          (d) the Trustee for 60 days after its receipt of such notice, request and offer of indemnity,
shall have neglected or refused to institute any such action, suit or proceeding; and

          (e) no direction that, in the opinion of the Trustee, is inconsistent with such written
request shall have been given to the Trustee by the Holders of a majority of the aggregate
principal amount of the Notes then outstanding within such 60-day period pursuant to Section 6.09,

it being understood and intended, and being expressly covenanted by the taker and Holder of every
Note with every other taker and Holder and the Trustee that no one or more Holders shall have any
right in any manner whatever by virtue of or by availing of any provision of this Indenture to
affect, disturb or prejudice the rights of any other Holder, or to obtain or seek to obtain
priority over or preference to any other such Holder, or to enforce any right under this Indenture,
except in the manner herein provided and for the equal, ratable and common benefit of all Holders
(except as otherwise provided herein) (it being understood that the Trustee does not have an
affirmative duty to ascertain whether or not such actions or forbearances are unduly prejudicial to
such Holders). For the protection and enforcement of this Section 6.06, each and every Holder and
the Trustee shall be entitled to such relief as can be given either at law or in equity.

          Notwithstanding any other provision of this Indenture and any provision of any Note, the right
of any Holder to receive payment or delivery, as the case may be, of (x) the principal (including
the Fundamental Change Repurchase Price, if applicable) of, (y) accrued and unpaid interest, if
any, on, and (z) the consideration due upon conversion of, such Note, on or after the respective
due dates expressed or provided for in such Note or in this Indenture, or to institute suit for the
enforcement of any such payment or delivery, as the case may be, on or after such respective dates
against the Company shall not be impaired or affected without the consent of such Holder.

          Section 6.07. Proceedings by Trustee. In case of an Event of Default the Trustee may in its
discretion proceed to protect and enforce the rights vested in it by this Indenture by such
appropriate judicial proceedings as are necessary to protect and enforce any of such rights, either
by suit in equity or by action at law or by proceeding in bankruptcy or otherwise, whether for the
specific enforcement of any covenant or agreement contained in this Indenture or in aid of the
exercise of any power granted in this Indenture, or to enforce any other legal or equitable right
vested in the Trustee by this Indenture or by law.

          Section 6.08. Remedies Cumulative and Continuing. Except as provided in the last paragraph
of Section 2.06, all powers and remedies given by this Article 6 to the Trustee or to the Holders
shall, to the extent permitted by law, be deemed cumulative and not exclusive of any

34

 

thereof or of
any other powers and remedies available to the Trustee or the Holders of the Notes, by judicial
proceedings or otherwise, to enforce the performance or observance of the covenants and agreements
contained in this Indenture, and no delay or omission of the Trustee or of any Holder of any of the
Notes to exercise any right or power accruing upon any Default or Event of Default shall impair any
such right or power, or shall be construed to be a waiver of any such Default or Event of Default
or any acquiescence therein; and, subject to the provisions of Section 6.06, every power and remedy
given by this Article 6 or by law to the Trustee or to the Holders may be exercised from time to
time, and as often as shall be deemed expedient, by the Trustee or by the Holders.

          Section 6.09. Direction of Proceedings and Waiver of Defaults by Majority of Holders. The
Holders of a majority of the aggregate principal amount of the Notes at the time outstanding
determined in accordance with Section 8.04 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 with respect to Notes; provided, however, that (a) such direction
shall not be in conflict with any rule of law or with this Indenture, and (b) the Trustee may take
any other action deemed proper by the Trustee that is not inconsistent with such direction. The
Trustee may refuse to follow any direction that it determines is unduly prejudicial to the rights
of any other Holder or that would involve the Trustee in personal liability. The Holders of a
majority in aggregate principal amount of the Notes at the time outstanding determined in
accordance with Section 8.04 may on behalf of the Holders of all of the Notes waive any past
Default or Event of Default hereunder and its consequences except (i) a default in the payment of
accrued and unpaid interest, if any, on, or the principal (including any Fundamental Change

Section 6.01, (ii) a failure by the Company to the consideration due upon conversion of the Notes
or (iii) a default in respect of a covenant or provision hereof which under Article 10 cannot be
modified or amended without the consent of each Holder of an outstanding Note affected. Upon any
such waiver the Company, the Trustee and the Holders of the Notes shall be restored to their former
positions and rights hereunder, but no such waiver shall extend to any subsequent or other Default
or Event of Default or impair any right consequent thereon. Whenever any Default or Event of
Default hereunder shall have been waived as permitted by this Section 6.09, said Default or Event
of Default shall for all purposes of the Notes and this Indenture be deemed to have been cured and
to be not continuing; but no such waiver shall extend to any subsequent or other Default or Event
of Default or impair any right consequent thereon.

          Section 6.10. Notice of Defaults. The Trustee shall, within 90 days after it receives
written notice of the occurrence and continuance of a Default, mail to all Holders as the names and
addresses of such Holders appear upon the Note Register, notice of all such Defaults, unless such
Defaults shall have been cured or waived before the giving of such notice; provided that, except in
the case of a Default in the payment of the principal of (including the Fundamental Change
Repurchase Price, if applicable), or accrued and unpaid interest on, any of the Notes or a Default
in the payment or delivery of the consideration due upon conversion, the Trustee shall be protected
in withholding such notice if and so long as it in good faith determines that the withholding of
such notice is in the interests of the Holders.

35

 

     Section 6.11. Undertaking to Pay Costs. All parties to this Indenture agree, and each Holder
of any Note by its acceptance thereof shall be deemed to have agreed, that any court may, in its
discretion, require, in any suit for the enforcement of any right or remedy under this Indenture,
or in any suit against the Trustee for any action taken or omitted by it as Trustee, the filing by
any party litigant in such suit of an undertaking to pay the costs of such suit and that such court

against any party litigant in such suit, having due regard to the merits and good faith of the
claims or defenses made by such party litigant; provided that the provisions of this Section 6.11
(to the extent permitted by law) shall not apply to any suit instituted by the Trustee, to any suit
instituted by any Holder, or group of Holders, holding in the aggregate more than 10% in principal
amount of the Notes at the time outstanding determined in accordance with Section 8.04, or to any
suit instituted by any Holder for the enforcement of the payment of the principal of or accrued and
unpaid interest, if any, on any Note (including, but not limited to, the Fundamental Change
Repurchase Price with respect to the Notes being repurchased as provided in this Indenture) on or
after the due date expressed or provided for in such Note or to any suit for the enforcement of the
right to convert any Note in accordance with the provisions of Article 14.

ARTICLE 7

Concerning the Trustee

     Section 7.01. Duties and Responsibilities of Trustee. The Trustee, prior to the occurrence
of an Event of Default and after the curing or waiver of all Events of Default that 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 that 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 such person’s own affairs; provided that if an Event of Default
occurs and is continuing, the Trustee will be under no obligation to exercise any of the rights or
powers under this Indenture at the request or direction of any of the Holders unless such Holders
have offered to the Trustee indemnity or security satisfactory to the Trustee against the costs,
expenses and liabilities that might be incurred by it in compliance with such request or direction.

     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 that may have occurred:

     (i) the duties and obligations of the Trustee shall be determined solely by the express
provisions of this Indenture, 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 against the Trustee; and

36

 

     (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 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 that 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 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 it shall be proved that the Trustee was
grossly negligent in ascertaining the pertinent facts;

     (c) the Trustee shall not be liable for any action it takes or omits to take in good faith
that it believes to be authorized or within the rights or powers conferred upon it by this
Indenture;

     (d) the Trustee shall not be liable with respect to any action taken or omitted to be taken by
it in good faith in accordance with the direction of the Holders of not less than a majority of the
aggregate principal amount of the Notes at the time outstanding determined as provided in Section
8.04 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;

     (e) 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;

     (f) the Trustee shall not be liable in respect of any payment (as to the correctness of
amount, entitlement to receive or any other matters relating to payment) or notice effected by the
Company or any Paying Agent or any records maintained by any co-Note Registrar with respect to the
Notes;

     (g) 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, unless such
Responsible Officer of the Trustee had actual knowledge of such event;

     (h) in the absence of written investment direction from the Company, all cash received by the
Trustee shall be placed in a non-interest bearing trust account, and in no event shall the Trustee
be liable for the selection of investments or for investment losses incurred thereon or for losses
incurred as a result of the liquidation of any such investment prior to its maturity date or the
failure of the party directing such investments prior to its maturity date or the failure of the
party directing such investment to provide timely written investment direction, and the Trustee
shall have no obligation to invest or reinvest any amounts held hereunder in the absence of such
written investment direction from the Company; and

37

 

     (i) in the event that the Trustee is also acting as Custodian, Note Registrar, Paying Agent,
Conversion Agent, Bid Solicitation Agent or transfer agent hereunder, the rights and protections
afforded to the Trustee pursuant to this Article 7 shall also be afforded to such Custodian, Note
Registrar, Paying Agent, Conversion Agent, Bid Solicitation Agent or transfer agent.

     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.

     Section 7.02. Reliance on Documents, Opinions, Etc. Except as otherwise provided in Section
7.01:

     (a) the Trustee may conclusively rely and shall be fully protected in acting or refraining
from acting upon any resolution, certificate, statement, instrument, opinion, report, notice,
request, consent, order, bond, Note, coupon or other paper or document believed by it in good faith
to be genuine and to have been signed or presented by the proper party or parties;

     (b) before the Trustee acts or refrains from acting, it may require an Officer’s Certificate
or an Opinion of Counsel or both. The Trustee will not be liable for any action it takes or omits
to take in good faith in reliance on such Officer’s Certificate or Opinion of Counsel;

     (c) any request, direction, order or demand of the Company mentioned herein shall be
sufficiently evidenced by an Officer’s Certificate (unless other evidence in respect thereof be
herein specifically prescribed); and any Board Resolution may be evidenced to the Trustee by a copy
thereof certified by the Secretary or an Assistant Secretary of the Company;

     (d) the Trustee may consult with counsel of its selection and require an Opinion of Counsel
and any advice of such counsel 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;

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

     (f) the Trustee shall not be required to give any bond or surety in respect of the performance
of its powers and duties hereunder;

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

38

 

enforceable by, the Trustee in each of its capacities hereunder, and each agent, custodian and
other Person employed to act hereunder;

     (h) the Trustee may request that the Company deliver a certificate setting forth the names of
individuals and/or titles of officers authorized at such time to take specified actions pursuant to
this Indenture (i.e., an incumbency certificate);

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

     (j) the permissive rights of the Trustee enumerated herein shall not be construed as duties.

     In no event shall the Trustee be responsible or liable for any special, indirect, punitive or
consequential loss or damage of any kind whatsoever (including, but not limited to, lost profits),
even if the Trustee has been advised of the likelihood of such loss or damage and regardless of the
form of action other than any such loss or damage caused by the Trustee’s gross negligence or
willful misconduct. The Trustee shall not be charged with knowledge of any Default or Event of
Default with respect to the Notes, unless either (1) a Responsible Officer shall have actual
knowledge of such Default or Event of Default or (2) written notice of such Default or Event of
Default shall have been given to the Trustee by the Company or by any Holder of the Notes.

     Section 7.03. No Responsibility for Recitals, Etc. The recitals contained herein and in the
Notes (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
Notes. The Trustee shall not be accountable for the use or application by the Company of any Notes
or the proceeds of any Notes authenticated and delivered by the Trustee in conformity with the
provisions of this Indenture.

     Section 7.04. Trustee, Paying Agents, Conversion Agents, Bid Solicitation Agent or Note
Registrar May Own Notes. The Trustee, any Paying Agent, any Conversion Agent, Bid Solicitation
Agent or Note Registrar, in its individual or any other capacity, may become the owner or pledgee
of Notes with the same rights it would have if it were not the Trustee, Paying Agent, Conversion
Agent, Bid Solicitation Agent or Note Registrar.

     Section 7.05. Monies and Shares of Common Stock to Be Held in Trust. All monies and any
shares of Common Stock 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 and any shares of Common Stock
held by the Trustee in trust hereunder need not be segregated from other funds or property except
to the extent required by law. The Trustee shall be under no liability for interest on any money
or shares of any Common Stock received by it hereunder except as may be agreed from time to time by
the Company and the Trustee.

39

 

     Section 7.06. 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, such 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 in
writing between the Trustee and the Company, 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 in any capacity thereunder
(including the reasonable compensation and the expenses and disbursements of its agents and counsel
and of all Persons not regularly in its employ) except any such expense, disbursement or advance as
shall have been caused by its gross negligence or willful misconduct. The Company also covenants
to indemnify the Trustee in any capacity under this Indenture and any other document or transaction
entered into in connection herewith and its agents and any authenticating agent for, and to hold
them harmless against, any loss, claim (whether asserted by the Company, any Holder or any other
Person), damage, liability or expense incurred without gross negligence or willful misconduct on
the part of the Trustee, its officers, directors, agents or employees, or such agent 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 7.06 to compensate or indemnify the Trustee and to pay or
reimburse the Trustee for expenses, disbursements and advances shall be secured by a senior claim
to which the Notes are hereby made subordinate on all money or property held or collected by the
Trustee, except, subject to the effect of Section 6.05, funds held in trust herewith for the
benefit of the Holders of particular Notes. The Trustee’s right to receive payment of any amounts
due under this Section 7.06 shall not be subordinate to any other liability or indebtedness of the
Company. The obligation of the Company under this Section 7.06 shall survive the satisfaction and
discharge of this Indenture and the earlier resignation or removal or the Trustee. The Company
need not pay for any settlement made without its consent, which consent shall not be unreasonably
withheld. The indemnification provided in this Section 7.06 shall extend to the officers,
directors, agents and employees of the Trustee.

     Without prejudice to any other rights available to the Trustee under applicable law, 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 Section 6.01(j) occurs, the expenses and the
compensation for the services are intended to constitute expenses of administration under any
bankruptcy, insolvency or similar laws.

     Section 7.07. [Intentionally Omitted]

     Section 7.08. 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. 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, 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

40

 

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

     Section 7.09. Resignation or Removal of Trustee. (a) The Trustee may at any time resign by
giving written notice of such resignation to the Company and by mailing notice thereof to the
Holders at their addresses as they shall appear on the Note Register. 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 within 60 days after the mailing of such
notice of resignation to the Holders, the resigning Trustee may, upon ten Business Days’ notice to
the Company and the Holders, at the expense of the Company, petition any court of competent
jurisdiction for the appointment of a successor trustee, or any Holder who has been a bona fide
holder of a Note or Notes for at least six months may, subject to the provisions of Section 6.11,
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.

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

     (i) the Trustee shall cease to be eligible in accordance with the provisions of Section
7.08 and shall fail to resign after written request therefor by the Company or by any such
Holder, or

     (ii) 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 either case, the Company may by a Board Resolution 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 6.11, any Holder who has been a bona
fide holder of a Note or Notes for at least six months may, on behalf of himself and all others
similarly situated, at the expense of the Company, petition any court of competent jurisdiction for
the removal of the Trustee and the appointment of a successor trustee. Such court may thereupon,
after such notice, if any, as it may deem proper and prescribe, remove the Trustee and appoint a
successor trustee.

     (c) The Holders of a majority in aggregate principal amount of the Notes at the time
outstanding, as determined in accordance with Section 8.04, may at any time remove the Trustee and
nominate a successor trustee by so notifying the Trustee and the Company in writing not less than
30 days prior to the effective date of such removal. If within ten days after notice to the
Company of such nomination the Company objects thereto, the Trustee so removed or any Holder, upon
the terms and conditions and otherwise as in Section 7.09(a) provided, may petition any court of
competent jurisdiction for an appointment of a successor trustee.

41

 

     (d) Any resignation or removal of the Trustee and appointment of a successor trustee pursuant
to any of the provisions of this Section 7.09 shall become effective upon acceptance of appointment
by the successor trustee as provided in Section 7.10.

     Section 7.10. Acceptance by Successor Trustee. Any successor trustee appointed as provided
in Section 7.09 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 amounts then due it pursuant to the provisions of
Section 7.06, 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 senior claim to which the Notes are hereby made subordinate on all
money or property held or collected by such trustee as such, except for funds held in trust for the
benefit of Holders of particular Notes, to secure any amounts then due it pursuant to the
provisions of Section 7.06.

     No successor trustee shall accept appointment as provided in this Section 7.10 unless at the
time of such acceptance such successor trustee shall be eligible under the provisions of Section
7.08.

     Upon acceptance of appointment by a successor trustee as provided in this Section 7.10, each
of the Company and the successor trustee, at the written direction and at the expense of the
Company shall mail or cause to be mailed notice of the succession of such trustee hereunder to the
Holders at their addresses as they shall appear on the Note 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.

     The Trustee shall have no responsibility or liability for the action or inaction of a
successor trustee.

     Section 7.11. Succession by Merger, Etc. Any corporation or other entity into which the
Trustee may be merged or converted or with which it may be consolidated, or any corporation or
other entity resulting from any merger, conversion or consolidation to which the Trustee shall be a
party, or any corporation or other entity succeeding to all or substantially all of the corporate
trust business of the Trustee (including the administration of 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 or other
entity succeeding to all or substantially all of the corporate trust business of the Trustee such
corporation or other entity shall be eligible under the provisions of Section 7.08.

     In case at the time such successor to the Trustee shall succeed to the trusts created by this
Indenture, any of the Notes shall have been authenticated but not delivered, any such successor

42

 

to the Trustee may adopt the certificate of authentication of any predecessor trustee or
authenticating agent appointed by such predecessor trustee, and deliver such Notes so
authenticated; and in case at that time any of the Notes shall not have been authenticated, any
successor to the Trustee or an authenticating agent appointed by such successor trustee may
authenticate such Notes either in the name of any predecessor trustee hereunder or in the name of
the successor trustee; and in all such cases such certificates shall have the full force which it
is anywhere in the Notes or in this Indenture provided that the certificate of the Trustee shall
have; provided, however, that the right to adopt the certificate of authentication of any
predecessor trustee or to authenticate Notes in the name of any predecessor trustee shall apply
only to its successor or successors by merger, conversion or consolidation.

     Section 7.12. 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 Notes 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 that the Company has indicated to
the Trustee should receive such application 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 any omission), the Trustee shall have received written
instructions in accordance with this Indenture in response to such application specifying the
action to be taken or omitted.

ARTICLE 8

Concerning the Holders

     Section 8.01. Action by Holders. Whenever in this Indenture it is provided that the Holders
of a specified percentage of the aggregate principal amount of the Notes may take any action
(including the making of any demand or request, the giving of any notice, consent or waiver or the
taking of any other action), the fact that at the time of taking any such action, the Holders of
such specified percentage have joined therein may be evidenced (a) by any instrument or any number
of instruments of similar tenor executed by Holders in person or by agent or proxy appointed in
writing, or (b) by the record of the Holders voting in favor thereof at any meeting of Holders duly
called and held in accordance with the provisions of Article 9, or (c) by a combination of such
instrument or instruments and any such record of such a meeting of Holders. Whenever the Company
or the Trustee solicits the taking of any action by the Holders of the Notes, the Company or the
Trustee may, but shall not be required to, fix in advance of such solicitation, a date as the
record date for determining Holders entitled to take such action. The record date if one is
selected shall be not more than fifteen days prior to the date of commencement of solicitation of
such action.

43

 

     Section 8.02. Proof of Execution by Holders. Subject to the provisions of Section 7.01,
Section 7.02 and Section 9.05, proof of the execution of any instrument by a Holder or its agent or
proxy shall be sufficient if made in accordance with such reasonable rules and regulations as may
be prescribed by the Trustee or in such manner as shall be satisfactory to the Trustee. The
holding of Notes shall be proved by the Note Register or by a certificate of the Note Registrar.
The record of any Holders’ meeting shall be proved in the manner provided in Section 9.06.

     Section 8.03. Who Are Deemed Absolute Owners. The Company, the Trustee, any authenticating
agent, any Paying Agent, any Conversion Agent and any Note Registrar may deem the Person in whose
name a Note shall be registered upon the Note Register to be, and may treat it as, the absolute
owner of such Note (whether or not such Note shall be overdue and notwithstanding any notation of
ownership or other writing thereon made by any Person other than the Company or any Note Registrar)
for the purpose of receiving payment of or on account of the principal of and (subject to Section
2.03) accrued and unpaid interest on such Note, for conversion of such Note and for all other
purposes; and neither the Company nor the Trustee nor any Paying Agent nor any Conversion Agent nor
any Note Registrar shall be affected by any notice to the contrary. All such payments or
deliveries so made to any Holder for the time being, or upon its order, shall be valid, and, to the
extent of the sums or shares of Common Stock so paid or delivered, effectual to satisfy and
discharge the liability for monies payable or shares deliverable upon any such Note.
Notwithstanding anything to the contrary in this Indenture or the Notes following an Event of
Default, any owner of a beneficial interest in a Global Note may directly enforce against the
Company, without the consent, solicitation, proxy, authorization or any other action of the
Depositary or any other Person, such owner’s right to exchange such beneficial interest for a Note
in certificated form in accordance with the provisions of this Indenture.

     Section 8.04. Company-Owned Notes Disregarded. In determining whether the Holders of the
requisite aggregate principal amount of Notes have concurred in any direction, consent, waiver or
other action under this Indenture, Notes that are owned by the Company or by any Person directly or
indirectly controlling or controlled by or under direct or indirect common control with the Company
shall be disregarded and deemed not to be outstanding for the purpose of any such determination;
provided that for the purposes of determining whether the Trustee shall be protected in
conclusively relying on any such direction, consent, waiver or other action only Notes that a
Responsible Officer actually knows are so owned shall be so disregarded. Notes so owned that have
been pledged in good faith may be regarded as outstanding for the purposes of this Section 8.04 if
the pledgee shall establish to the satisfaction of the Trustee the pledgee’s right to so act with
respect to such Notes and that the pledgee is not the Company or a Person directly or indirectly
controlling or controlled by or under direct or indirect common control with the Company. In the
case of a dispute as to such right, any decision or indecision by the Trustee taken upon the advice
of counsel shall be full protection to the Trustee. Upon request of the Trustee, the Company shall
furnish to the Trustee promptly an Officer’s Certificate listing and identifying all Notes, if any,
known by the Company to be owned or held by or for the account of any of the above described
Persons; and, subject to Section 7.01, the Trustee shall be entitled to accept such Officer’s
Certificate as conclusive evidence of the facts therein set forth and of the fact that all Notes
not listed therein are outstanding for the purpose of any such determination.

44

 

     Section 8.05. Revocation of Consents; Future Holders Bound. At any time prior to (but not
after) the evidencing to the Trustee, as provided in Section 8.01, of the taking of any action by
the Holders of the percentage of the aggregate principal amount of the Notes specified in this
Indenture in connection with such action, any Holder of a Note that is shown by the evidence to be
included in the Notes the Holders of which have consented to such action may, by filing written
notice with the Trustee at its Corporate Trust Office and upon proof of holding as provided in
Section 8.02, revoke such action so far as concerns such Note. Except as aforesaid, any such
action taken by the Holder of any Note shall be conclusive and binding upon such Holder and upon
all future Holders and owners of such Note and of any Notes issued in exchange or substitution
therefor or upon registration of transfer thereof, irrespective of whether any notation in regard
thereto is made upon such Note or any Note issued in exchange or substitution therefor or upon
registration of transfer thereof.

the establishment of any record date pursuant to Section 8.01, shall be mailed to Holders of such
Notes at their addresses as they shall appear on the Note Register. Such notice shall also be
mailed to the Company. Such notices shall be mailed not less than 20 nor more than 90 days prior
to the date fixed for the meeting.

     Any meeting of Holders shall be valid without notice if the Holders of all Notes then
outstanding are present in person or by proxy or if notice is waived before or after the meeting by

45

 

the Holders of all Notes then outstanding, and if the Company and the Trustee are either
present by duly authorized representatives or have, before or after the meeting, waived notice.

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

     Section 9.04. Qualifications for Voting. To be entitled to vote at any meeting of Holders a
Person shall (a) be a Holder of one or more Notes on the record date pertaining to such meeting or
(b) be a Person appointed by an instrument in writing as proxy by a Holder of one or more Notes on
the record date pertaining to such meeting. The only Persons who shall be entitled to be present
or to speak at any meeting of Holders shall be the Persons entitled to vote at such meeting and
their counsel and any representatives of the Trustee and its counsel and any representatives of the
Company and its counsel.

     Section 9.05. Regulations. Notwithstanding any other provisions of this Indenture, the
Trustee may make such reasonable regulations as it may deem advisable for any meeting of Holders,
in regard to proof of the holding of Notes and of the appointment of proxies, and in regard to the
appointment and duties of inspectors of votes, the submission and examination of proxies,
certificates and other evidence of the right to vote, and such other matters concerning the conduct
of the meeting as it shall think fit.

     The Trustee shall, by an instrument in writing, appoint a temporary chairman of the meeting,
unless the meeting shall have been called by the Company or by Holders as provided in Section 9.03,
in which case the Company or the Holders calling the meeting, as the case may be, shall in like
manner appoint a temporary chairman. A permanent chairman and a permanent secretary of the meeting
shall be elected by vote of the Holders of a majority in principal amount of the Notes represented
at the meeting and entitled to vote at the meeting.

     Subject to the provisions of Section 8.04, at any meeting of Holders each Holder or
proxyholder shall be entitled to one vote for each $1,000 principal amount of Notes held or
represented by him; provided, however, that no vote shall be cast or counted at any meeting in
respect of any Note challenged as not outstanding and ruled by the chairman of the meeting to be
not outstanding. The chairman of the meeting shall have no right to vote other than by virtue of
Notes held by it or instruments in writing as aforesaid duly designating it as the proxy to vote on
behalf of other Holders. Any meeting of Holders duly called pursuant to the provisions of Section
9.02 or Section 9.03 may be adjourned from time to time by the Holders of a majority of the
aggregate principal amount of Notes represented at the meeting, whether or not constituting a
quorum, and the meeting may be held as so adjourned without further notice.

     Section 9.06. Voting. The vote upon any resolution submitted to any meeting of Holders shall
be by written ballot on which shall be subscribed the signatures of the Holders or of their

46

 

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

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

     Section 9.07. No Delay of Rights by Meeting. Nothing contained in this Article 9 shall be
deemed or construed to authorize or permit, by reason of any call of a meeting of Holders or any
rights expressly or impliedly conferred hereunder to make such call, any hindrance or delay in the
exercise of any right or rights conferred upon or reserved to the Trustee or to the Holders under
any of the provisions of this Indenture or of the Notes. Nothing contained in this Article 9 shall
be deemed or construed to limit any Holder’s actions pursuant to the applicable procedures of the
Depositary so long as the Notes are issued in global form.

ARTICLE 10

Supplemental Indentures

     Section 10.01. Supplemental Indentures Without Consent of Holders. The Company, when
authorized by the resolutions of the Board of Directors and the Trustee, at the Company’s expense,
may from time to time and at any time enter into an indenture or indentures supplemental hereto for
one or more of the following purposes:

     (a) to cure any ambiguity, omission, defect or inconsistency that does not materially
adversely affect Holders of the Notes;

     (b) to provide for the assumption by a Successor Company of the obligations of the Company
under this Indenture pursuant to Article 11;

     (c) to add guarantees with respect to the Notes;

     (d) to secure the Notes;

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

47

 

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

     (g) to provide for the acceptance of appointment by a successor trustee pursuant to Section
7.10 or to facilitate the administration of the trusts by more than one trustee; or

     (h) to conform the provisions of this Indenture or the Notes to the “Description of notes”
section of the Offering Memorandum, to the extent such provision in the “Description of notes”
section was intended to be a verbatim recitation of a provision of this Indenture, as evidenced by
an Officer’s Certificate.

     Upon the written request of the Company, the Trustee is hereby authorized to join with the
Company in the execution of any such supplemental indenture, to make any further appropriate
agreements and stipulations that may be therein contained, but the Trustee shall not be obligated
to, but may in its discretion, enter into any supplemental indenture that affects the Trustee’s own
rights, duties or immunities under this Indenture or otherwise.

     Any supplemental indenture authorized by the provisions of this Section 10.01 may be executed
by the Company and the Trustee without the consent of the Holders of any of the Notes at the time
outstanding, notwithstanding any of the provisions of Section 10.02.

     Section 10.02. Supplemental Indentures with Consent of Holders. With the consent (evidenced
as provided in Article 8) of the Holders of at least a majority of the aggregate principal amount
of Notes then outstanding (determined in accordance with Article 8 and including, without
limitation, consents obtained in connection with a repurchase of, or tender or exchange offer for,
Notes), the Company, when authorized by the resolutions of the Board of Directors and the Trustee,
at the Company’s expense, may from time to time and at any time enter into an indenture or
indentures supplemental hereto for the purpose of adding any provisions to or changing in any
manner or eliminating any of the provisions of this Indenture or any supplemental indenture or of
modifying in any manner the rights of the Holders; provided, however, that, without the consent of
each Holder of an outstanding Note affected, no such supplemental indenture shall:

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

     (b) reduce the rate of or extend the stated time for payment of interest on any Note;

     (c) reduce the principal of or extend the Maturity Date of any Note;

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

     (e) reduce the Fundamental Change Repurchase Price of any Note or amend or modify in any
manner adverse to the Holders the Company’s obligation to make such payments, whether through an
amendment or waiver of provisions in the covenants, definitions or otherwise;

     (f) make any Note payable in a currency other than that stated in the Note;

     (g) change the ranking of the Notes;

48

 

     (h) impair the right of any Holder to receive payment of principal of (including the
Fundamental Change Repurchase Price, if applicable) and interest on such Holder’s Notes on or after
the due dates therefor or to institute suit for the enforcement of any payment on or with respect
to such Holder’s Note; or

     (i) make any change in this Article 10 that requires each Holder’s consent or in the waiver
provisions in Section 6.01 or Section 6.09.

     Upon the written request of the Company, and upon the filing with the Trustee of evidence of
the consent of Holders as aforesaid and subject to Section 10.05, the Trustee shall join with the
Company in the execution of such supplemental indenture unless such supplemental indenture affects
the Trustee’s own rights, duties or immunities under this Indenture or otherwise, in which case the
Trustee may in its discretion, but shall not be obligated to, enter into such supplemental
indenture.

     Holders do not need under this Section 10.02 to approve the particular form of any proposed
supplemental indenture. It shall be sufficient if such Holders approve the substance thereof.
After any such supplemental indenture becomes effective, the Company shall mail to the Holders a
notice briefly describing such supplemental indenture. However, the failure to give such notice to
all the Holders, or any defect in the notice, will not impair or affect the validity of the
supplemental indenture.

     Section 10.03. Effect of Supplemental Indentures. Upon the execution of any supplemental
indenture pursuant to the provisions of this Article 10, this Indenture shall be and be deemed to
be modified and amended in accordance therewith and the respective rights, limitation of rights,
obligations, duties and immunities under this Indenture of the Trustee, the Company and the Holders
shall thereafter be determined, exercised and enforced hereunder subject in all respects to such
modifications and amendments and all the terms and conditions of any such supplemental indenture
shall be and be deemed to be part of the terms and conditions of this Indenture for any and all
purposes.

     Section 10.04. Notation on Notes. Notes authenticated and delivered after the execution of
any supplemental indenture pursuant to the provisions of this Article 10 may, at the Company’s
expense, bear a notation in form approved by the Trustee as to any matter provided for in such
supplemental indenture. If the Company or the Trustee shall so determine, new Notes so modified as
to conform, in the opinion of the Trustee and the Board of Directors, to any modification of this
Indenture contained in any such supplemental indenture may, at the Company’s expense, be prepared
and executed by the Company, authenticated by the Trustee (or an authenticating agent duly
appointed by the Trustee pursuant to Section 17.10) and delivered in exchange for the Notes then
outstanding, upon surrender of such Notes then outstanding.

     Section 10.05. Evidence of Compliance of Supplemental Indenture to Be Furnished Trustee. In
addition to the documents required by Section 17.05, the Trustee shall receive and shall be fully
protected in conclusively relying upon an Officer’s Certificate and an Opinion of Counsel as
conclusive evidence that any supplemental indenture executed pursuant hereto complies with the
requirements of this Article 10, is permitted or authorized by this Indenture, such Opinion of
Counsel to include a customary legal opinion as to the enforceability under New

49

 

York law of such supplemental indenture, which opinion may contain customary exceptions and
qualifications.

ARTICLE 11

Consolidation, Merger, Sale, Conveyance and Lease

     Section 11.01. Company May Consolidate, Etc. on Certain Terms. Subject to the provisions of
Section 11.02, the Company shall not consolidate with, merge with or into, or sell, convey,
transfer or lease all or substantially all of its properties and assets to another Person, unless:

     (a) the resulting, surviving or transferee Person (the “Successor Company”), if not the
Company, shall be a corporation organized and existing under the laws of the United States of
America, any State thereof or the District of Columbia, and the Successor Company (if not the
Company) shall expressly assume, by supplemental indenture all of the obligations of the Company
under the Notes and this Indenture; and

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

     For purposes of this Section 11.01, the sale, conveyance, transfer or lease of all or
substantially all of the properties and assets of one or more Subsidiaries of the Company to
another Person, which properties and assets, if held by the Company instead of such Subsidiaries,
would constitute all or substantially all of the properties and assets of the Company on a
consolidated basis, shall be deemed to be the sale, conveyance, transfer or lease of all or
substantially all of the properties and assets of the Company to another Person.

     Section 11.02. Successor Corporation to Be Substituted. In case of any such consolidation,
merger, sale, conveyance, transfer or lease and upon the assumption by the Successor Company, by
supplemental indenture, executed and delivered to the Trustee and satisfactory in form to the
Trustee, of the due and punctual payment of the principal of and accrued and unpaid interest on all
of the Notes, the due and punctual delivery or payment, as the case may be, of any consideration
due upon conversion of the Notes and the due and punctual performance of all of the covenants and
conditions of this Indenture to be performed by the Company, such Successor Company (if not the
Company) shall succeed to and be substituted for the Company, with the same effect as if it had
been named herein as the party of the first part, except in the case of a lease of all or
substantially all of the Company’s properties and assets. Such Successor Company thereupon may
cause to be signed, and may issue either in its own name or in the name of the Company any or all
of the Notes issuable hereunder which theretofore shall not have been signed by the Company and
delivered to the Trustee; and, upon the order of such Successor Company instead of the Company and
subject to all the terms, conditions and limitations in this Indenture prescribed, the Trustee
shall authenticate and shall deliver, or cause to be authenticated and delivered, any Notes that
previously shall have been signed and delivered by the Officers of the Company to the Trustee for
authentication, and any Notes that such Successor Company thereafter shall cause to be signed and
delivered to the Trustee for that purpose. All the Notes so issued shall in all respects have the
same legal rank

50

 

and benefit under this Indenture as the Notes theretofore or thereafter issued in accordance
with the terms of this Indenture as though all of such Notes had been issued at the date of the
execution hereof. In the event of any such consolidation, merger, sale, conveyance or transfer
(but not in the case of a lease), upon compliance with this Article 11 the Person named as the
“Company” in the first paragraph of this Indenture (or any successor that shall thereafter have
become such in the manner prescribed in this Article 11) may be dissolved, wound up and liquidated
at any time thereafter and, except in the case of a lease, such Person shall be released from its
liabilities as obligor and maker of the Notes and from its obligations under this Indenture and the
Notes.

     In case of any such consolidation, merger, sale, conveyance, transfer or lease, such changes
in phraseology and form (but not in substance) may be made in the Notes thereafter to be issued as
may be appropriate.

     Section 11.03. Evidence to Be Given to Trustee. No consolidation, merger, sale, conveyance,
transfer or lease shall be effective unless the Trustee shall receive an Officer’s Certificate and
an Opinion of Counsel as conclusive evidence that any such consolidation, merger, sale, conveyance,
transfer or lease and any such assumption and, if a supplemental indenture is required in
connection with such transaction, such supplemental indenture, complies with the provisions of this
Article 11.

ARTICLE 12

Immunity of Incorporators, Stockholders, Officers and Directors

     Section 12.01. Indenture and Notes Solely Corporate Obligations. No recourse for the payment
of the principal of or accrued and unpaid interest on any Note, nor for any claim based thereon or
otherwise in respect thereof, and no recourse under or upon any obligation, covenant or agreement
of the Company in this Indenture or in any supplemental indenture or in any Note, nor because of
the creation of any indebtedness represented thereby, shall be had against any incorporator,
stockholder, employee, agent, Officer or director or Subsidiary, as such, past, present or future
of the Company or any successor corporation, whether by virtue of any constitution, statute or rule
of law, or by the enforcement of any assessment or penalty or otherwise; it being expressly
understood that all such liability is hereby expressly waived and released as a condition of, and
as a consideration for, the execution of this Indenture and the issue of the Notes.

51

 

ARTICLE 13

[Intentionally Omitted]

ARTICLE 14

Conversion of Notes

     Section 14.01. Conversion Privilege. (a) Subject to and upon compliance with the provisions
of this Article 14, each Holder of a Note shall have the right, at such Holder’s option, to convert
all or any portion (if the portion to be converted is $1,000 principal amount or an integral
multiple thereof) of such Note (i) subject to satisfaction of the conditions described in Section
14.01(b), at any time prior to the close of business on the Business Day immediately preceding June
15, 2016 under the circumstances and during the periods set forth in Section 14.01(b), and (ii)
irrespective of the conditions described in Section 14.01(b), on or after June 15, 2016 and prior
to the close of business on the second Scheduled Trading Day immediately preceding the Maturity
Date, in each case, at an initial conversion rate of 17.4092 shares of Common Stock (subject to
adjustment as provided in Section 14.04, the “Conversion Rate”) per $1,000 principal amount of
Notes (subject to the settlement provisions of Section 14.02, the “Conversion Obligation”).

     (b) (i) Prior to the close of business on the Business Day immediately preceding June 15,
2016, the Notes may be surrendered for conversion during the five Business-Day period immediately
after any ten consecutive Trading-Day period (the “Measurement Period”) in which the Trading Price
per $1,000 principal amount of Notes, as determined following a request by a Holder of Notes in
accordance with this subsection (b)(i), for each Trading Day of the Measurement Period was less
than 98% of the product of the Last Reported Sale Price of the Common Stock and the Conversion Rate
on each such Trading Day. The Trading Prices shall be determined by the Bid Solicitation Agent
pursuant to this subsection (b)(i) and the definition of Trading Price set forth in this Indenture.
The Company shall provide written notice to the Bid Solicitation Agent of the three independent
nationally recognized securities dealers selected by the Company pursuant to the definition of
Trading Price, along with appropriate contact information for each. The Bid Solicitation Agent
shall have no obligation to determine the Trading Price per $1,000 principal amount of Notes unless
the Company has requested such determination, and the Company shall have no obligation to make such
request unless a Holder of at least $5 million aggregate principal amount of Notes provides the
Company with reasonable evidence that the Trading Price per $1,000 principal amount of Notes would
be less than 98% of the product of the Last Reported Sale Price of the Common Stock and the
Conversion Rate, at which time the Company shall instruct the Bid Solicitation Agent to determine
the Trading Price per $1,000 principal amount of Notes beginning on the next Trading Day and on
each successive Trading Day until the Trading Price per Note is greater than or equal to 98% of the
product of the Last Reported Sale Price of the Common Stock and the Conversion Rate. If the
Company does not instruct the Bid Solicitation Agent to determine the Trading Price per $1,000
principal amount of Notes when obligated as provided in the preceding sentence, or if the Company
instructs the Bid Solicitation Agent to obtain bids and the Bid Solicitation Agent fails to make
such determination, then, in either case, the Trading Price per $1,000 principal amount of Notes
shall be deemed to be less than 98% of the product of the Last Reported Sale Price of the

52

 

Common Stock and the Conversion Rate on each Trading Day of such failure. If the Trading
Price condition set forth above has been met, the Company shall so notify the Holders, the Trustee
and the Conversion Agent (if other than the Trustee) in writing. If, at any time after the Trading
Price condition set forth above has been met, the Trading Price per $1,000 principal amount of
Notes 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 Notes, the
Trustee and the Conversion Agent (if other than the Trustee) in writing.

     (ii) If, prior to the close of business on the Business Day immediately preceding June
15, 2016, the Company elects to:

     (A) issue to all or substantially all holders of its Common Stock any rights,
options or warrants entitling them, for a period of not more than 60 calendar days
after the announcement date of such issuance, to subscribe for or purchase shares
of its Common Stock, at a price per share that is less than the average of the Last
Reported Sale Prices of the Common Stock for the 10 consecutive Trading-Day period
ending on, and including, the Trading Day immediately preceding the date of
announcement of such issuance; or

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

then, in either case, the Company shall notify all Holders of the Notes, the Trustee and the
Conversion Agent (if other than the Trustee) in writing at least 60 Scheduled Trading Days prior to
the Ex-Dividend Date for such issuance or distribution. Once the Company has given such notice,
the Notes may be surrendered for conversion at any time until the earlier of (1) the close of
business on the Business Day immediately preceding the Ex-Dividend Date for such issuance or
distribution and (2) the Company’s announcement that such issuance or distribution will not take
place, even if the Notes are not otherwise convertible at such time.

     (iii) If a transaction or event that (x) constitutes a Fundamental Change occurs, (y)
constitutes a Make-Whole Fundamental Change occurs or (z) would have constituted a
Fundamental Change but for the Listed Stock Exception occurs, in each case prior to the
close of business on the Business Day immediately preceding June 15, 2016, regardless of
whether a Holder has the right to require the Company to repurchase the Notes pursuant to
Section 15.02, then the Notes may be surrendered for conversion at any time from or after
the effective date of the transaction or event until the earlier of (A) 35 Trading Days
after the actual effective date of such transaction or event or, if such transaction or
event also constitutes a Fundamental Change, until the related Fundamental Change Repurchase
Date, and (B) the second Scheduled Trading Day immediately preceding the Maturity Date. The
Company shall notify Holders, the Trustee and the Conversion Agent (if other than the
Trustee) in writing no later than five Business Days following the date the Company publicly
announces such transaction or event.

53

 

     (iv) Prior to the close of business on the Business Day immediately preceding June 15,
2016, the Notes may be surrendered for conversion during any calendar quarter commencing
after the calendar quarter ending on September 30, 2011 (and only during such calendar
quarter), if the Last Reported Sale Price of the Common Stock for at least 20 Trading Days
(whether or not consecutive) during the period of 30 consecutive Trading Days ending on the
last Trading Day of the immediately preceding calendar quarter is greater than 150% of the
Conversion Price on each applicable Trading Day. The Conversion Agent, on behalf of the
Company, shall determine at the beginning of each calendar quarter commencing after
September 30, 2011 whether the Notes may be surrendered for conversion in accordance with
this clause (iv) and shall notify the Company and the Trustee if the Notes become
convertible in accordance with this clause (iv).

     Section 14.02. Conversion Procedure; Settlement Upon Conversion.

     (a) Except as provided in Section 14.03(b) and Section 14.07(a), upon conversion of any Note,
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 the converting Holder, in respect
of each $1,000 principal amount of Notes being converted, a “Settlement Amount” equal to the sum of
the Daily Settlement Amounts for each of the 50 Trading Days during the applicable Observation
Period for such Note, together with cash, if applicable, in lieu of any fractional share of Common
Stock in accordance with subsection (j) of this Section 14.02.

     (i) All conversions occurring on or after June 15, 2016 shall be settled using the same
forms and amounts of consideration. Prior to June 15, 2016, the Company shall use the same
forms and amounts of consideration for all conversions occurring on the same Conversion
Date, but the Company shall not have any obligation to use the same forms and amounts with
respect to conversions that occur on different Trading Days. If the Company elects to
settle all or a portion of its Conversion Obligation in excess of the principal portion of
the Notes being converted in cash, the Company shall inform converting Holders through the
Trustee of such election (the “Settlement Notice”) no later than the close of business on
the Trading Day immediately following the related Conversion Date (or, in the case of any
conversions occurring on or after June 15, 2016, no later than June 15, 2016) and the
Company shall indicate in such Settlement Notice the percentage of each share issuable upon
conversion in excess of the principal portion of the Notes being converted that will be paid
in cash (the “Cash Percentage”). If the Company does not so deliver a Settlement Notice
prior to the deadline set forth in the immediately preceding sentence, the Company shall no
longer have the right to elect a Cash Percentage and the Company shall settle its Conversion
Obligation by paying cash in respect of the principal portion of the converted Notes and
delivering shares of Common Stock in respect of the remainder, if any, of its Conversion
Obligation in excess of the aggregate principal portion of the Notes being converted as set
forth herein.

     (ii) The Daily Settlement Amounts (if applicable), the Daily Net Settlement Amounts (if
applicable) and the Daily Conversion Values (if applicable) shall be determined by the
Company promptly following the last day of the applicable Observation Period. Promptly
after such determination of the Daily Settlement Amounts,

54

 

the Daily Net Settlement Amounts or the Daily Conversion Values, as the case may be,
and the amount of cash payable in lieu of any fractional share, the Company shall notify the
Trustee and the Conversion Agent (if other than the Trustee) in writing of the Daily
Settlement Amounts, the Daily Net Settlement Amounts or the Daily Conversion Values, as the
case may be, and the amount of cash payable in lieu of fractional shares of Common Stock.
The Trustee and the Conversion Agent (if other than the Trustee) shall have no
responsibility for any such determination.

     (b) Subject to Section 14.02(e), before any Holder of a Note shall be entitled to convert a
Note as set forth above, such Holder shall (i) in the case of a Global Note, comply with the
procedures of the Depositary in effect at that time and, if required, pay funds equal to interest
payable on the next Interest Payment Date to which such Holder is not entitled as set forth in
Section 14.02(h) and, if required, pay all transfer and similar taxes, if any, and (ii) in the case
of a Physical Note (1) complete, manually sign and deliver an irrevocable notice to the Conversion
Agent as set forth in the Form of Notice of Conversion (or a facsimile thereof) (a “Notice of
Conversion”) at the office of the Conversion Agent and state in writing therein the principal
amount of Notes to be converted and the name or names (with addresses) in which such Holder wishes
the certificate or certificates for any shares of Common Stock to be delivered upon settlement of
the Conversion Obligation to be registered, (2) surrender such Notes, duly endorsed to the Company
or in blank (and accompanied by appropriate endorsement and transfer documents), at the office of
the Conversion Agent, (3) if required, furnish appropriate endorsements and transfer documents, (4)
if required, pay all transfer or similar taxes and (5) if required, pay funds equal to interest
payable on the next Interest Payment Date to which such Holder is not entitled as set forth in
Section 14.02(h). The Trustee (and, if different, the Conversion Agent) shall notify the Company
of any conversion pursuant to this Article 14 on the Conversion Date for such conversion. No
Notice of Conversion with respect to any Notes may be surrendered by a Holder thereof if such
Holder has also delivered a Fundamental Change Repurchase Notice to the Company in respect of such
Notes and not validly withdrawn such Fundamental Change Repurchase Notice in accordance with
Section 15.03.

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

     (c) A Note shall be deemed to have been converted immediately prior to the close of business
on the date (the “Conversion Date”) that the Holder has complied with the requirements set forth in
subsection (b) above. If any shares of Common Stock are due to converting Holders, the Company
shall issue or cause to be issued, and deliver to the Conversion Agent or to such Holder, or such
Holder’s nominee or nominees, certificates or a book-entry transfer through the Depositary for the
full number of shares of Common Stock to which such Holder shall be entitled in satisfaction of the
Company’s Conversion Obligation.

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

55

 

any service charge by the converting Holder but with payment of a sum sufficient to cover any
transfer tax or similar governmental charge required by law or that may be imposed in connection
therewith as a result of the name of the Holder of the new Notes issued upon such conversion being
different from the name of the Holder of the old Notes surrendered for such conversion.

     (e) If a Holder submits a Note for conversion, the Company shall pay any documentary, stamp or
similar issue or transfer tax due on the issue of any shares of Common Stock upon conversion,
unless the tax is due because the Holder requests such shares to be issued in a name other than the
Holder’s name, in which case the Holder shall pay that tax. The Conversion Agent may refuse to
deliver the certificates representing the shares of Common Stock being issued in a name other than
the Holder’s name until the Trustee receives a sum sufficient to pay any tax that is due by such
Holder in accordance with the immediately preceding sentence.

     (f) Except as provided in Section 14.04, no adjustment shall be made for dividends on any
shares issued upon the conversion of any Note as provided in this Article 14.

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

     (h) Upon conversion, a Holder shall not receive any separate cash payment for accrued and
unpaid interest, if any, except as set forth below. The Company’s settlement of the Conversion
Obligation shall be deemed to satisfy in full its obligation to pay the principal amount of the
Note and accrued and unpaid interest, if any, to, but not including, the Conversion Date. As a
result, accrued and unpaid interest, if any, to, but not including, the Conversion Date shall be
deemed to be paid in full rather than cancelled, extinguished or forfeited. Upon a conversion of
Notes, accrued and unpaid interest will be deemed to be paid first out of the cash paid upon such
conversion. Notwithstanding the foregoing, if Notes are converted after the close of business on a
Regular Record Date, Holders of such Notes as of the close of business on such Regular Record Date
will receive the full amount of interest payable on such Notes on the corresponding Interest
Payment Date notwithstanding the conversion. Notes surrendered for conversion during the period
from the close of business on any Regular Record Date to the open of business on the immediately
following Interest Payment Date must be accompanied by funds equal to the amount of interest
payable on the Notes so converted; provided that no such payment shall be required (1) for
conversions following the Regular Record Date immediately preceding the Maturity Date; (2) if the
Company has specified a Fundamental Change Repurchase Date that is after a Regular Record Date and
on or prior to the Business Day immediately following the corresponding Interest Payment Date; or
(3) to the extent of any Defaulted Amounts, if any Defaulted Amounts exists at the time of
conversion with respect to such Note.

     (i) The Person in whose name the certificate for any shares of Common Stock delivered upon
conversion is registered shall be treated as a stockholder of record as of the close of business on
the last Trading Day of the related Observation Period. Upon a conversion of Notes, such Person
shall no longer be a Holder of such Notes surrendered for conversion.

56

 

     (j) The Company shall not issue any fractional share of Common Stock upon conversion of the
Notes and shall instead pay cash in lieu of any fractional share of Common Stock issuable upon
conversion based on the Daily VWAP on the Last Trading Day of the applicable Observation Period.
For each Note surrendered for conversion, the full number of shares that shall be issued upon
conversion thereof shall be computed on the basis of the aggregate Daily Settlement Amounts for the
applicable Observation Period, and any fractional shares remaining after such computation shall be
paid in cash.

     Section 14.03. Increased Conversion Rate Applicable to Certain Notes Surrendered in
Connection with Make-Whole Fundamental Changes. (a) If a Make-Whole Fundamental Change occurs
prior to the Maturity Date and a Holder elects to convert its Notes in connection with such
Make-Whole Fundamental Change, the Company shall, under the circumstances described below, increase
the Conversion Rate for the Notes so surrendered for conversion by a number of additional shares of
Common Stock (the “Additional Shares”), as described below. A conversion of Notes shall be deemed
for these purposes to be “in connection with” such Make-Whole Fundamental Change if the applicable
Conversion Date occurs during the period from, and including, 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 a Make-Whole Fundamental Change that would
have been a Fundamental Change but for the Majority Ownership Exception, the 35th Trading Day
immediately following the Effective Date of such Make-Whole Fundamental Change).

     (b) Upon surrender of Notes for conversion in connection with a Make-Whole Fundamental Change
pursuant to Section 14.01(b)(iii), the Company shall satisfy the related Conversion Obligation in
accordance with Section 14.02 based on the Conversion Rate as increased to reflect the Additional
Shares pursuant to the table below; provided, however, that if, at the effective time of a
Make-Whole Fundamental Change described in clause (b) of the definition of Fundamental Change, the
Reference Property is composed entirely of cash, for any conversion of Notes following the
Effective Date of such Make-Whole Fundamental Change, the Conversion Obligation shall be calculated
based solely on the Stock Price for the transaction and shall be deemed to be an amount of cash per
$1,000 principal amount of converted Notes equal to the Conversion Rate (including any adjustment
for Additional Shares), multiplied by such Stock Price. In such event, the Conversion Obligation
will be determined and shall be paid to Holders in cash on the third Business Day following the
Conversion Date. The Company shall notify the Holders of Notes of the Effective Date of any
Make-Whole Fundamental Change no later than five Business Days after such Effective Date.

     (c) The number of Additional Shares, if any, by which the Conversion Rate shall be increased
shall be determined by reference to the table below, 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 (or deemed to be paid) per share of the Common Stock in the Make-Whole Fundamental
Change. If the holders of the Common Stock receive only cash in a Make-Whole Fundamental Change
described in clause (b) of the definition of 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 the Common Stock over the five Trading-Day period ending on, and including, the Trading
Day immediately preceding the Effective Date of the Make-Whole Fundamental Change. The Board of
Directors shall make

57

 

appropriate adjustments to the Stock Price, in its good faith determination, to account for
any adjustment to the Conversion Rate that becomes effective, or any event requiring an adjustment
to the Conversion Rate where the Ex-Dividend Date of the event occurs, during such five consecutive
Trading-Day period.

     (d) The Stock Prices set forth in the column headings of the table below shall be adjusted as
of any date on which the Conversion Rate of the Notes 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
giving rise to the Stock Price adjustment and the denominator of which is the Conversion Rate as so
adjusted. The number of Additional Shares set forth in the table below shall be adjusted in the
same manner and at the same time as the Conversion Rate as set forth in Section 14.04.

     (e) The following table sets forth the number of Additional Shares to be received per $1,000
principal amount of Notes pursuant to this Section 14.03 for each Stock Price and Effective Date
set forth below:

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

     (i) if the Stock Price is between two Stock Prices in the table above or the Effective
Date is between two Effective Dates in the table above, 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 earlier and later Effective Dates,
as applicable, based on a 365-day year;

     (ii) if the Stock Price is greater than $140.00 per share (subject to adjustment in the
same manner as the Stock Prices set forth in the column headings of the table above pursuant
to subsection (d) above), no Additional Shares shall be added to the Conversion Rate; and

     (iii) if the Stock Price is less than $46.70 per share (subject to adjustment in the
same manner as the Stock Prices set forth in the column headings of the table above pursuant
to subsection (d) above), no Additional Shares shall be added to the Conversion Rate.

58

 

Notwithstanding the foregoing, in no event shall the total number of shares of Common Stock
issuable upon conversion exceed 21.4132 per $1,000 principal amount of Notes, subject to adjustment
in the same manner as the Conversion Rate pursuant to Section 14.04.

     (f) Nothing in this Section 14.03 shall prevent an adjustment to the Conversion Rate pursuant
to Section 14.04 in respect of a Make-Whole Fundamental Change.

     Section 14.04. 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 shall
not make any adjustments to the Conversion Rate if Holders of the Notes participate (other than in
the case of a share split or share combination), at the same time and upon the same terms as
holders of the Common Stock and solely as a result of holding the Notes, in any of the transactions
described in this Section 14.04, without having to convert their Notes, as if they held a number of
shares of Common Stock equal to the Conversion Rate, multiplied by the principal amount (expressed
in thousands) of Notes held by such Holder.

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

	 	 	 	 	 

	where,
	 	 	 	 
	 
	 	 	 	 
	CR0

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

	 	=
	 	the Conversion Rate in effect immediately after
the open of business on such Ex-Dividend Date or
effective date;
	 
	 	 	 	 
	OS0

	 	=
	 	the number of shares of Common Stock outstanding
immediately prior to the open of business on such
Ex-Dividend Date or effective date; and
	 
	 	 	 	 
	OS’

	 	=
	 	the number of shares of Common Stock outstanding
immediately after giving effect to such dividend,
distribution, share split or share combination.

Any adjustment made under this Section 14.04(a) shall become effective immediately after the open
of business on the Ex-Dividend Date for such dividend or distribution, or immediately after the
open of business on the effective date for such share split or share combination, as applicable.
If any dividend or distribution of the type described in this Section 14.04(a) is declared but not
so paid or made, the Conversion Rate shall be immediately readjusted, effective as of the date the
Board of Directors determines not to pay such dividend or distribution, to the Conversion Rate that
would then be in effect if such dividend or distribution had not been declared.

59

 

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

	 	 	 	 	 

	where,
	 	 	 	 
	 
	 	 	 	 
	CR0

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

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

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

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

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

Any increase made under this Section 14.04(b) shall be made successively whenever any such rights,
options or warrants are issued and shall become effective immediately after the open of business on
the Ex-Dividend Date for such issuance. To the extent that shares of the Common Stock are not
delivered after the expiration of such rights, options or warrants, the Conversion Rate shall be
decreased to the Conversion Rate that would then be in effect had the increase with respect to the
issuance of such rights, options or warrants been made on the basis of delivery of only the number
of shares of Common Stock actually delivered. If such rights, options or warrants are not so
issued, the Conversion Rate shall be decreased to the Conversion Rate that would then be in effect
if such Ex-Dividend Date for such issuance had not occurred.

     For purposes of this Section 14.04(b), in determining whether any rights, options or warrants
entitle the holders to subscribe for or purchase shares of the Common Stock at less than such
average of the Last Reported Sale Prices of the Common Stock for the 10 consecutive Trading-Day
period ending on, and including, the Trading Day immediately preceding the date of announcement for
such issuance, and in determining the aggregate offering price of such shares of Common Stock,
there shall be taken into account any consideration received by the

60

 

Company for such rights, options or warrants and any amount payable on exercise or conversion
thereof, the value of such consideration, if other than cash, to be determined by the Board of
Directors.

     (c) If the Company distributes shares of its Capital Stock, evidences of its indebtedness,
other assets or property or rights, options or warrants to acquire its Capital Stock or other
securities, to all or substantially all holders of the Common Stock, excluding (i) dividends,
distributions or issuances as to which an adjustment was effected pursuant to Section 14.04(a) or
Section 14.04(b), (ii) dividends or distributions paid exclusively in cash as to which an
adjustment was effected pursuant to Section 14.04(d), and (iii) Spin-Offs as to which the
provisions set forth below in this Section 14.04(c) shall apply (any of such shares of Capital
Stock, evidences of indebtedness, other assets or property or rights, options or warrants to
acquire Capital Stock or other securities of the Company, the “Distributed Property”), then the
Conversion Rate shall be increased based on the following formula:

	 	 	 	 	 

	where,
	 	 	 	 
	 
	 	 	 	 
	CR0

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

	 	=
	 	the Conversion Rate in effect immediately after
the open 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, and including, the
Trading Day immediately preceding the Ex-Dividend
Date for such distribution; and
	 
	 	 	 	 
	FMV

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

Any increase made under the portion of this Section 14.04(c) above shall become effective
immediately after the open of business on the Ex-Dividend Date for such distribution. If such
distribution is not so paid or made, the Conversion Rate shall be decreased to the Conversion Rate
that would then be in effect if such dividend or distribution had not been declared.
Notwithstanding the foregoing, if “FMV” (as defined above) is equal to or greater than
“SP0” (as defined above), in lieu of the foregoing increase, each Holder of a Note shall
receive, in respect of each $1,000 principal amount thereof, at the same time and upon the same
terms as holders of the Common Stock receive the Distributed Property, the amount and kind of
Distributed Property such Holder would have received if such Holder owned a number of shares of
Common Stock equal to the Conversion Rate in effect on the Ex-Dividend Date for the distribution.
If the Board of Directors determines the “FMV” (as defined above) of any distribution for purposes
of this Section 14.04(c) by reference to the actual or when-issued trading market for any
securities, it shall in doing so consider the prices in such market over the same period used in
computing the

61

 

Last Reported Sale Prices of the Common Stock over the 10 consecutive Trading-Day period ending on,
and including, the Trading Day immediately preceding the Ex-Dividend Date for such distribution.

     With respect to an adjustment pursuant to this Section 14.04(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 of the
Company, that are, or, when issued, will be, listed or admitted for trading on a U.S. national
securities exchange (a “Spin-Off”), the Conversion Rate shall be increased based on the following
formula:

	 	 	 	 	 

	where,
	 	 	 	 
	 
	 	 	 	 
	CR0

	 	=
	 	the Conversion Rate in effect immediately prior
to the close of business on the effective date of
the Spin-Off;
	 
	 	 	 	 
	CR’

	 	=
	 	the Conversion Rate in effect immediately after
the close of business on the effective date of
the Spin-Off;
	 
	 	 	 	 
	FMV0

	 	=
	 	the average of the Last Reported Sale Prices of
the Capital Stock or similar equity interest
distributed to holders of the Common Stock
applicable to one share of the Common Stock
(determined by reference to the definition of
Last Reported Sale Price as set forth in Section
1.01 as if references therein to Common Stock
were to such Capital Stock or similar equity
interest) over the first 10 consecutive
Trading-Day period after, and including, the
Ex-Dividend Date of the Spin-Off (the “Valuation
Period”); and
	 
	 	 	 	 
	MP0

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

The adjustment to the Conversion Rate under the preceding paragraph shall occur at the open of
business on the last Trading Day of the Valuation Period, but shall be given effect as of the close
of business on the effective date of the Spin-Off; provided that if settlement of a converted Note
occurs during the Valuation Period, the Company will pay cash and deliver shares of its Common
Stock, if any, on the third Business Day immediately following the last day of the Valuation
Period.

     For purposes of this Section 14.04(c) (and subject in all respect to Section 14.11), rights,
options 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, including Common Stock (either
initially or under certain circumstances), which rights, options or warrants, until the occurrence
of a specified event or events (“Trigger Event”): (i) are deemed to be transferred with such shares
of the Common Stock; (ii) are not exercisable; and (iii) are also issued in respect of future
issuances of the Common Stock, shall be deemed not to have been distributed

62

 

for purposes of this Section 14.04(c) (and no adjustment to the Conversion Rate under this
Section 14.04(c) will be required) until the occurrence of the earliest Trigger Event, whereupon
such rights, options or 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 14.04(c).
If any such right, option or warrant, including any such existing rights, options or warrants
distributed prior to the date of this Indenture, are subject to events, upon the occurrence of
which such rights, options or warrants become exercisable to purchase different securities,
evidences of indebtedness or other assets, then the date of the occurrence of any and each such
event shall be deemed to be the date of distribution and Ex-Dividend Date with respect to new
rights, options or warrants with such rights (in which case the existing rights, options or
warrants shall be deemed to terminate and expire on such date without exercise by any of the
holders thereof). In addition, in the event of any distribution (or deemed distribution) of
rights, options or warrants, or any Trigger Event or other event (of the type described in the
immediately 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 14.04(c) was
made, (1) in the case of any such rights, options or warrants that shall all have been redeemed or
purchased without exercise by any holders thereof, upon such final redemption or purchase (x) the
Conversion Rate shall be readjusted as if such rights, options or warrants had not been issued and
(y) the Conversion Rate shall then again be readjusted to give effect to such distribution, deemed
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 or holders of Common Stock with
respect to such rights, options or warrants (assuming such holder had retained such rights, options
or warrants), made to all holders of Common Stock as of the date of such redemption or purchase,
and (2) in the case of such rights, options or warrants that shall have expired or been terminated
without exercise by any holders thereof, the Conversion Rate shall be readjusted as if such rights,
options and warrants had not been issued.

     For purposes of Section 14.04(a), Section 14.04(b) and this Section 14.04(c), any dividend or
distribution to which this Section 14.04(c) is applicable that also includes one or both of:

     (A) a dividend or distribution of shares of Common Stock to which Section 14.04(a) is
applicable (the “Clause A Distribution”); or

     (B) a dividend or distribution of rights, options or warrants to which Section 14.04(b) is
applicable (the “Clause B Distribution”),

then (1) such dividend or distribution, other than the Clause A Distribution and the Clause B
Distribution, shall be deemed to be a dividend or distribution to which this Section 14.04(c) is
applicable (the “Clause C Distribution”) and any Conversion Rate adjustment required by this
Section 14.04(c) with respect to such Clause C Distribution shall then be made, and (2) the Clause
A Distribution and Clause B Distribution shall be deemed to immediately follow the Clause C
Distribution and any Conversion Rate adjustment required by Section 14.04(a) and Section 14.04(b)
with respect thereto shall then be made, except that, if determined by the Company (I) the
“Ex-Dividend Date” of the Clause A Distribution and the Clause B Distribution shall be deemed to be
the Ex-Dividend Date of the Clause C Distribution and (II) any shares of Common Stock included in
the Clause A Distribution or Clause B Distribution shall be deemed

63

 

not to be “outstanding immediately prior to the open of business on such Ex-Dividend Date or
effective date” within the meaning of Section 14.04(a) or “outstanding immediately prior to the
open of business on such Ex-Dividend Date” within the meaning of Section 14.04(b).

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

	 	 	 	 	 

	where,
	 	 	 	 
	 
	 	 	 	 
	CR0

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

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

	 	=
	 	the Last Reported Sale Price of the 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 its Common Stock.

Any increase pursuant to this Section 14.04(d) shall become effective immediately after the open of
business on the Ex-Dividend Date for such dividend or distribution. If such dividend or
distribution is not so paid, the Conversion Rate shall be decreased, effective as of the date the
Board of Directors determines not to make or pay such dividend or distribution, to be the
Conversion Rate that would then be in effect if such dividend or distribution had not been
declared. Notwithstanding the foregoing, if “C” (as defined above) is equal to or greater than
“SP0” (as defined above), in lieu of the foregoing increase, each Holder of a Note shall
receive, for each $1,000 principal amount of Notes, at the same time and upon the same terms as
holders of shares of the Common Stock, the amount of cash that such Holder would have received if
such Holder owned a number of shares of Common Stock equal to the Conversion Rate on the
Ex-Dividend Date for such cash dividend or distribution.

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

	 	 	 	 	 

	where,
	 	 	 	 

64

 

	 	 	 	 	 

	CR0

	 	=
	 	the Conversion Rate in effect immediately prior to
the close of business on the 10th Trading Day
immediately following, and including, the Trading
Day next succeeding the date such tender or
	 
	 	 	 	 
	CR’

	 	=
	 	exchange offer expires;
the Conversion Rate in effect immediately after
the close of business on the 10th Trading Day
immediately following, and including, the Trading
Day next succeeding the date such tender or
exchange offer expires;
	 
	 	 	 	 
	AC

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

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

	 	=
	 	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 of Common Stock accepted for
purchase or exchange in such tender or exchange
offer); and
	 
	 	 	 	 
	SP’

	 	=
	 	the average of the Last Reported Sale Prices of
the Common Stock over the 10 consecutive
Trading-Day period (the “Averaging Period”)
commencing on, and including, the Trading Day next
succeeding the date such tender or exchange offer
expires.

The adjustment to the Conversion Rate under this Section 14.04(e) shall occur at the open of
business on the Trading Day immediately following the last day of the Averaging Period but will be
given effect immediately after the open of business on the Trading Day immediately following the
last date on which tenders or exchanges may be made pursuant to such tender or exchange offer;
provided that if settlement of a converted Note occurs during the Averaging Period, the Company
will pay cash and deliver shares of its Common Stock, if any, on the third Business Day immediately
following the last day of the Averaging Period.

     (f) Except as stated herein, the Company shall not adjust the Conversion Rate for the issuance
of shares of its Common Stock or any securities convertible into or exchangeable for shares of its
Common Stock or the right to purchase shares of its Common Stock or such convertible or
exchangeable securities (including as consideration for a merger, purchase or similar transaction).

     (g) In addition to those adjustments required by clauses (a), (b), (c), (d) and (e) of this
Section 14.04, and to the extent permitted by applicable law and subject to the applicable rules of
The NASDAQ Global Select Market, the Company from time to time may increase the Conversion Rate by
any amount for a period of at least 20 Business Days if the Board of Directors determines that such
increase would be in the Company’s best interest. In addition, to the extent permitted by
applicable law and subject to the applicable rules of The NASDAQ

65

 

Global Select Market, the Company may (but is not required to) increase the Conversion Rate to
avoid or diminish any income tax to holders of Common Stock or rights to purchase Common Stock in
connection with a dividend or distribution of shares (or rights to acquire shares) or similar
event. Whenever the Conversion Rate is increased pursuant to either of the preceding two
sentences, the Company shall mail to the Holder of each Note at its last address appearing on the
Note Register 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.

     (h) Notwithstanding anything to the contrary in this Article 14, the Conversion Rate shall not
be adjusted:

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

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

     (iii) upon the repurchase of any shares of Common Stock pursuant to an open-market
share repurchase program or other buy-back transaction that is not a tender offer or
exchange offer of the nature described under Section 14.04(e);

     (iv) for a third-party tender offer (other than a tender offer by any Subsidiary of the
Company as described under Section 14.04(e));

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

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

     (vii) for accrued and unpaid interest, if any.

     The Company shall not be required to make an adjustment pursuant to clauses (a), (b), (c), (d)
or (e) of this Section 14.04 unless such adjustment would result in a change of at least 1% of the
then effective Conversion Rate. However, the Company shall carry forward any adjustment that the
Company would otherwise have to make and take that adjustment into account in any subsequent
adjustment. Notwithstanding the foregoing, all such carried-forward adjustments shall be made with
respect to the Notes (i) in connection with any subsequent adjustment to the Conversion Rate of at
least 1% of the Conversion Rate (when such carried-forward adjustments are taken into account),
(ii) on the Conversion Date for any Notes and (iii) on each Trading Day of any Observation Period.
All calculations and other determinations under this Article 14 shall

66

 

be made by the Company and shall be made to the nearest one-ten thousandth (1/10,000) of a
share.

     (i) Whenever the Conversion Rate is adjusted as herein provided, the Company shall promptly
file with the Trustee (and the Conversion Agent if not the Trustee) an Officer’s Certificate
setting forth the Conversion Rate after such adjustment and setting forth a brief statement of the
facts requiring such adjustment. Unless and until a Responsible Officer of the Trustee shall have
received such Officer’s Certificate, the Trustee shall not be deemed to have knowledge of any
adjustment of the Conversion Rate and may assume 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 Holder at its last address appearing on the Note
Register of this Indenture. Failure to deliver such notice shall not affect the legality or
validity of any such adjustment.

     (j) For purposes of this Section 14.04, 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.

     Section 14.05. Adjustments of Prices. Whenever any provision of this Indenture requires the
Company to calculate the Last Reported Sale Prices, the Daily VWAPs, the Daily Conversion Values or
the Daily Settlement Amounts over a span of multiple days (including an Observation Period and the
period for determining the Stock Price for purposes of a Make-Whole Fundamental Change), the
Company shall make appropriate adjustments to each 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 when such Last Reported Sale
Prices, Daily VWAPs, Daily Conversion Values or Daily Settlement Amounts are to be calculated.

     Section 14.06. Shares to Be Fully Paid. The Company shall provide, free from preemptive
rights, out of its authorized but unissued shares or shares held in treasury, sufficient shares of
Common Stock to provide for conversion of the Notes from time to time as such Notes are presented
for conversion (assuming that at the time of computation of such number of shares, all such Notes
would be converted by a single Holder).

     Section 14.07. Effect of Recapitalizations, Reclassifications and Changes of the Common
Stock.

     (a) In the case of:

     (i) any recapitalization, reclassification or change of the Common Stock (other than
changes resulting from a subdivision or combination),

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

67

 

     (iii) any sale, lease or other transfer to a third party of the consolidated assets of
the Company and the Company’s Subsidiaries substantially as an entirety or

     (iv) any statutory share exchange,

in each case, as a result of which the Common Stock would be converted into, or exchanged for,
stock, other securities, other property or assets (including cash or any combination thereof) (any
such event, a “Merger Event”), then, at and after the effective time of such Merger Event, the
right to convert each $1,000 principal amount of Notes shall be changed into a right to convert
such principal amount of Notes into the kind and amount of shares of stock, other securities or
other property or assets (including cash or any combination thereof) that a holder of a number of
shares of Common Stock equal to the Conversion Rate immediately prior to such Merger Event would
have owned or been entitled to receive (the “Reference Property”, with each “unit of Reference
Property” meaning the kind and amount of Reference Property that a holder of one share of Common
Stock is entitled to receive) upon such Merger Event and, prior to or at the effective time of such
Merger Event, the Company or the successor or purchasing Person, as the case may be, shall execute
with the Trustee a supplemental indenture permitted under Section 10.01(f) providing for such
change in the right to convert each $1,000 principal amount of Notes; provided, however, that at
and after the effective time of the Merger Event the Conversion Obligation shall be calculated and
settled in accordance with Section 14.02 such that (A) the amount otherwise payable in cash upon
conversion of the Notes as set forth under Section 14.02 shall continue to be payable in cash, (B)
the Company shall continue to have the right to elect to determine the form of consideration to be
paid or delivered, as the case may be, in respect of the remainder, if any, of the Conversion
Obligation in excess of the principal amount of the Notes being converted as set forth under
Section 14.02, (C) the number of shares of Common Stock, if any, otherwise deliverable upon
conversion of the Notes in accordance with Section 14.02 shall instead be deliverable in the amount
and type of Reference Property that a holder of that number of shares of Common Stock would have
received in such Merger Event and (D) the Daily VWAP shall be calculated based on the value of a
unit of Reference Property.

     If the Merger Event causes the Common Stock to be converted into, or exchanged for, the right
to receive more than a single type of consideration (determined based in part upon any form of
stockholder election), then (i) the Reference Property into which the Notes 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 an election, and (ii) the unit of
Reference Property for purposes of the immediately preceding paragraph shall refer to the
consideration referred to in clause (i) attributable to one share of Common Stock. If the holders
receive only cash in such Merger Event, then for all conversions that occur after the effective
date of such Merger Event (x) the consideration due upon conversion of each $1,000 principal amount
of Notes shall be solely cash in an amount equal to the Conversion Rate in effect on the Conversion
Date (as may be increased by any Additional Shares pursuant to Section 14.03), multiplied by the
price paid per share of Common Stock in such Merger Event and (y) the Company shall satisfy the
Conversion Obligation by paying cash to converting Holders on the third Business Day immediately
following the Conversion Date. The Company shall notify Holders, the Trustee and the Conversion
Agent (if other than the Trustee) of such weighted average as soon as practicable after such
determination is made.

68

 

     Such supplemental indenture described in the second immediately preceding paragraph shall
provide for adjustments that shall be as nearly equivalent as is possible to the adjustments
provided for in this Article 14. If, in the case of any Merger Event, the Reference Property
includes shares of stock, securities or other property or assets (including cash or any combination
thereof) of a Person other than the successor or purchasing corporation, as the case may be, in
such Merger Event, then such supplemental indenture shall also be executed by such other Person and
shall contain such additional provisions to protect the interests of the Holders of the Notes as
the Board of Directors shall reasonably consider necessary by reason of the foregoing, including to
the extent required by the Board of Directors and practicable the provisions providing for the
purchase rights set forth in Article 15.

     (b) In the event the Company shall execute a supplemental indenture pursuant to subsection (a)
of this Section 14.07, the Company shall promptly file with the Trustee an Officer’s Certificate
briefly stating the reasons therefore, the kind or amount of cash, securities or property or asset
that will comprise the Reference Property after any such Merger Event, any adjustment to be made
with respect thereto and that all conditions precedent have been complied with, and shall promptly
mail notice thereof to all Holders. The Company shall cause notice of the execution of such
supplemental indenture to be mailed to each Holder, at its address appearing on the Note Register
provided for in this Indenture, within 20 days after execution thereof. Failure to deliver such
notice shall not affect the legality or validity of such supplemental indenture.

     (c) The Company shall not become a party to any Merger Event unless its terms are consistent
with this Section 14.07. None of the foregoing provisions shall affect the right of a holder of
Notes to convert its Notes into cash and shares of Common Stock, if any, as set forth in Section
14.01 and Section 14.02 prior to the effective date of such Merger Event.

     (d) The above provisions of this Section shall similarly apply to successive Merger Events.

     Section 14.08. Certain Covenants. (a) The Company covenants that any shares of Common Stock
issued upon conversion of Notes will be validly issued, fully paid and non-assessable by the
Company and free from all taxes, liens and charges with respect to the issue thereof.

     (b) The Company further covenants that if at any time the Common Stock shall be listed on any
national securities exchange or automated quotation system, the Company will list and keep listed,
so long as the Common Stock shall be so listed on such exchange or automated quotation system, any
Common Stock issuable upon conversion of the Notes.

     Section 14.09. Responsibility of Trustee. The Trustee and any other Conversion Agent shall
not at any time be under any duty or responsibility to any Holder to determine the Conversion Rate
(or any adjustment thereto) or whether any facts exist that may require any adjustment (including
any increase) of the Conversion Rate, or with respect to the nature or extent or calculation of any
such adjustment when made, or with respect to the method employed, 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

69

 

value (or the kind or amount) of any shares of Common Stock, or of any securities, property or
cash that may at any time be issued or delivered upon the conversion of any Note; and the Trustee
and any other Conversion Agent make no representations with respect thereto. Neither the Trustee
nor any Conversion Agent shall be responsible for any failure of the Company to issue, transfer or
deliver any shares of Common Stock or stock certificates or other securities or property or cash
upon the surrender of any Note for the purpose of conversion or to comply with any of the duties,
responsibilities or covenants of the Company contained in this Article. Without limiting the
generality of the foregoing, neither the Trustee nor any Conversion Agent shall be under any
responsibility to determine the correctness of any provisions contained in any supplemental
indenture entered into pursuant to Section 14.07 relating either to the kind or amount of shares of
stock or securities or property (including cash) receivable by Holders upon the conversion of their
Notes after any event referred to in such Section 14.07 or to any adjustment to be made with
respect thereto, but, subject to the provisions of Section 7.01, may accept (without any
independent investigation) as conclusive evidence of the correctness of any such provisions, and
shall be protected in conclusively relying upon, the Officer’s Certificate (which the Company shall
be obligated to file with the Trustee prior to the execution of any such supplemental indenture)
with respect thereto. Neither the Trustee nor the Conversion Agent shall be responsible for
determining whether any event contemplated by Section 14.01(b) has occurred that makes the Notes
eligible for conversion or no longer eligible therefor until the Company has delivered to the
Trustee and the Conversion Agent the notices referred to in Section 14.01(b) with respect to the
commencement or termination of such conversion rights, on which notices the Trustee and the
Conversion Agent may conclusively rely, and the Company agrees to deliver such notices to the
Trustee and the Conversion Agent immediately after the occurrence of any such event or at such
other times as shall be provided for in Section 14.01(b). The Conversion Agent (if other than the
Company or an Affiliate of the Company) shall have the same protection under this Section 14.09 as
the Trustee.

     Section 14.10. Notice to Holders Prior to Certain Actions. In case of any voluntary or
involuntary dissolution, liquidation or winding-up of the Company or any of its Subsidiaries, then
(unless notice of such event is otherwise required pursuant to another provision of this Indenture)
the Company shall cause to be filed with the Trustee and the Conversion Agent (if other than the
Trustee) and to be mailed to each Holder at its address appearing on the Note Register, as promptly
as possible but in any event at least 20 days prior to the applicable date hereinafter specified, a
notice stating the date on which such 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 dissolution, liquidation or winding-up. Failure to give such notice, or any defect therein,
shall not affect the legality or validity of such dissolution, liquidation or winding-up.

     Section 14.11. Stockholder Rights Plans. To the extent that the Company has a rights plan in
effect upon conversion of the Notes, each share of Common Stock, if any, issued upon such
conversion 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 such stockholder rights plan, as the same
may be amended from time to time. If at the time of conversion, however, the rights have

70

 

separated from the shares of Common Stock in accordance with the provisions of the applicable
stockholder rights plan so that the Holders would not be entitled to receive any rights in respect
of Common Stock, if any, issuable upon conversion of the Notes, the Conversion Rate shall be
adjusted at the time of separation as if the Company distributed to all or substantially all
holders of Common Stock shares of Capital Stock of the Company, evidences of its indebtedness,
other assets or property or rights, options or warrants to acquire its Capital Stock or other
securities as provided in Section 14.04(c), subject to readjustment in the event of the expiration,
termination or redemption of such rights.

     Section 14.12. Limit on Issuance of Shares of Common Stock Upon Conversion. Notwithstanding
anything to the contrary in this Indenture, if an event occurs that would result in an increase in
the Conversion Rate by an amount in excess of limitations imposed by any shareholder approval rules
or listing standards of any national or regional securities exchange that are applicable to the
Company, the Company will, at its option, either obtain stockholder approval of any issuance of
Common Stock upon conversion of the Notes in excess such limitations or deliver cash in lieu of any
shares of Common Stock otherwise deliverable upon conversions in excess of such limitations based
on the Daily VWAP on each Trading Day of the relevant Observation Period in respect of which, in
lieu of delivering shares of Common Stock, the Company delivers cash pursuant to this Section
14.12.

ARTICLE 15

Repurchase of Notes at Option of Holders

     Section 15.01. [Intentionally Omitted]

     Section 15.02. Repurchase at Option of Holders Upon a Fundamental Change. (a) If a
Fundamental Change occurs at any time, each Holder shall have the right, at such Holder’s option,
to require the Company to repurchase for cash all of such Holder’s Notes, or any portion thereof
that is equal to $1,000 or an integral multiple of $1,000, on the date (the “Fundamental Change
Repurchase Date”) specified by the Company that is not less than 20 Business Days or more than 35
Business Days following the date of the Fundamental Change Company Notice at a repurchase price
equal to 100% of the principal amount thereof, plus accrued and unpaid interest thereon to, but
excluding, the Fundamental Change Repurchase Date (the “Fundamental Change Repurchase Price”),
unless the Fundamental Change Repurchase Date falls after a Regular Record Date but on or prior to
the Interest Payment Date to which such Regular Record Date relates, in which case the Company
shall instead pay the full amount of accrued and unpaid interest to Holders of record as of such
Regular Record Date, and the Fundamental Change Repurchase Price shall be equal to 100% of the
principal amount of Notes to be repurchased pursuant to this Article 15.

     (b) Repurchases of Notes under this Section 15.02 shall be made, at the option of the Holder
thereof, upon:

     (i) delivery to the Paying Agent by a Holder of a duly completed notice (the
“Fundamental Change Repurchase Notice”) substantially in the form set forth in Attachment 2
to the form of Note attached hereto as Exhibit A, if the Notes are Physical

71

 

Notes, or in compliance with the Depositary’s procedures for surrendering interests in
Global Notes, if the Notes are Global Notes, in each case on or before the close of business
on the Business Day immediately preceding the Fundamental Change Repurchase Date; and

     (ii) delivery of the Notes, if the Notes are Physical Notes, to the Paying Agent at any
time after delivery of the Fundamental Change Repurchase Notice (together with all necessary
endorsements for transfer) at the Corporate Trust Office of the Paying Agent, or book-entry
transfer of the Notes, if the Notes are Global Notes, in compliance with the procedures of
the Depositary, in each case such delivery being a condition to receipt by the Holder of the
Fundamental Change Repurchase Price therefor.

     The Fundamental Change Repurchase Notice in respect of any Notes to be repurchased shall
state:

     (i) in the case of Physical Notes, the certificate numbers of the Notes to be delivered
for repurchase;

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

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

provided, however, that if the Notes are Global Notes, the Fundamental Change Repurchase Notice
must comply with appropriate Depositary procedures.

     Notwithstanding anything herein to the contrary, any Holder delivering to the Paying Agent the
Fundamental Change Repurchase Notice contemplated by this Section 15.02 shall have the right to
withdraw, in whole or in part, such Fundamental Change Repurchase Notice at any time prior to the
close of business on the Business Day immediately preceding the Fundamental Change Repurchase Date
by delivery of a written notice of withdrawal to the Paying Agent in accordance with Section 15.03.

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

     (c) On or before the 20th day after the occurrence of a Fundamental Change, the Company shall
provide to all Holders of Notes and the Trustee and the Paying Agent (in the case of a Paying Agent
other than the Trustee) a notice (the “Fundamental Change Company Notice”) of the occurrence of the
Fundamental Change and of the repurchase right at the option of the Holders arising as a result
thereof. Such notice shall be by first class mail or, in the case of Global Notes, in accordance
with the applicable procedures of the Depositary. Each Fundamental Change Company Notice shall
specify:

     (i) the events causing the Fundamental Change;

     (ii) the date of the Fundamental Change;

72

 

     (iii) the last date on which a Holder may exercise the repurchase right pursuant to
this Article 15;

     (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 Conversion Rate and any adjustments to the Conversion Rate;

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

     (ix) the procedures that Holders must follow to require the Company to repurchase their
Notes.

     No failure of the Company to give the foregoing notices and no defect therein shall limit the
Holders’ repurchase rights or affect the validity of the proceedings for the repurchase of the
Notes pursuant to this Section 15.02.

     At the Company’s written request and upon 15 days prior notice, the Trustee shall give such
notice in the Company’s name and at the Company’s expense; provided, however, that, in all cases,
the text of such Fundamental Change Company Notice shall be prepared by the Company.

     (d) Notwithstanding the foregoing, no Notes may be repurchased by the Company on any date at
the option of the Holders upon a Fundamental Change if the principal amount of the Notes has been
accelerated, and such acceleration has not been rescinded, on or prior to such date (except in the
case of an acceleration resulting from a Default by the Company in the payment of the Fundamental
Change Repurchase Price with respect to such Notes). The Paying Agent will promptly return to the
respective Holders thereof any Physical Notes held by it during the acceleration of the Notes
(except in the case of an acceleration resulting from a Default by the Company in the payment of
the Fundamental Change Repurchase Price with respect to such Notes), or any instructions for
book-entry transfer of the Notes in compliance with the procedures of the Depositary shall be
deemed to have been cancelled, and, upon such return or cancellation, as the case may be, the
Fundamental Change Repurchase Notice with respect thereto shall be deemed to have been withdrawn.

     Section 15.03. Withdrawal of Fundamental Change Repurchase Notice. (a) A Fundamental Change
Repurchase Notice may be withdrawn (in whole or in part) by means of a written notice of withdrawal
delivered to the Paying Agent in accordance with this Section 15.03

73

 

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 Notes with respect to which such notice of withdrawal
is being submitted,

     (ii) if Physical Notes have been issued, the certificate number of the Note in respect
of which such notice of withdrawal is being submitted, and

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

provided, however, that if the Notes are Global Notes, the notice must comply with appropriate
procedures of the Depositary.

     Section 15.04. Deposit of Fundamental Change Repurchase Price. (a) The Company will deposit
with the Trustee (or other Paying Agent appointed by the Company, or if the Company is acting as
its own Paying Agent, set aside, segregate and hold in trust as provided in Section 4.04) on or
prior to 11:00 a.m., New York City time, on the Fundamental Change Repurchase Date an amount of
money sufficient to repurchase all of the Notes to be repurchased at the appropriate Fundamental
Change Repurchase Price. Subject to receipt of funds and/or Notes by the Trustee (or other Paying
Agent appointed by the Company), payment for Notes surrendered for repurchase (and not withdrawn
prior to the close of business on the Business Day immediately preceding the Fundamental Change
Repurchase Date) will be made on the later of (i) the Fundamental Change Repurchase Date with
respect to such Note (provided the Holder has satisfied the conditions in Section 15.02) and (ii)
the time of book-entry transfer or the delivery of such Note to the Trustee (or other Paying Agent
appointed by the Company) by the Holder thereof in the manner required by Section 15.02 by mailing
checks for the amount payable to the Holders of such Notes entitled thereto as they shall appear in
the Note Register; provided, however, that payments to the Depositary shall be made by wire
transfer of immediately available funds to the account of the Depositary or its nominee. The
Trustee shall, promptly after such payment and upon written demand by the Company, return to the
Company any funds in excess of the Fundamental Change Repurchase Price.

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

     (c) Upon surrender of a Note that is to be repurchased in part pursuant to Section 15.02, the
Company shall execute and the Trustee shall authenticate and deliver to the Holder a new

74

 

Note in an authorized denomination equal in principal amount to the unrepurchased portion of
the Note surrendered.

     Section 15.05. Covenant to Comply with Applicable Laws Upon Repurchase of Notes. In
connection with any repurchase offer, the Company will, if required:

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

Notes hereunder, including under Section 2.04, Section 2.05, Section 2.06, Section 2.07, Section
10.04 and Section 15.04 as fully to all intents and purposes as though the authenticating agent had
been expressly authorized by this Indenture and those Sections to authenticate and deliver Notes.
For all purposes of this Indenture, the authentication and delivery of Notes by the authenticating
agent shall be deemed to be authentication and delivery of such Notes “by the Trustee” and a
certificate of authentication executed on behalf of the Trustee by an authenticating agent shall be
deemed to satisfy any requirement hereunder or in the Notes for the Trustee’s certificate of
authentication. Such authenticating agent shall at all times be a Person eligible to serve as
trustee hereunder pursuant to Section 7.08.

or with which it may be consolidated, or any corporation or other entity resulting from any merger,

or other entity succeeding to the corporate trust business of any authenticating agent, shall be
the successor of the authenticating agent hereunder, if such successor corporation or other entity
is otherwise eligible under this Section, without the execution or filing of any paper or any
further act on the part of the parties hereto or the authenticating agent or such successor
corporation or other entity.

     Any authenticating agent may at any time resign by giving written notice of resignation to the
Trustee and to the Company. The Trustee may at any time terminate the agency of any authenticating
agent by giving written notice of termination to such authenticating agent and to the Company.

authenticating agent shall cease to be eligible under this Section, the Trustee may appoint a
successor authenticating agent (which may be the Trustee), shall give written notice of such
appointment to the Company and shall mail notice of such appointment to all Holders as the names
and addresses of such Holders appear on the Note Register.

     The Company agrees to pay to the authenticating agent from time to time such compensation for
its services as agreed in writing although the Company may terminate the authenticating agent (if
other than the Trustee), if it determines such authenticating agent’s fees to be unreasonable.

     The provisions of Section 7.02, Section 7.03, Section 7.04, Section 8.03 and this Section
17.10 shall be applicable to any authenticating agent.

     If an authenticating agent is appointed pursuant to this Section, the Notes may have endorsed
thereon, in addition to the Trustee’s certificate of authentication, an alternative certificate of
authentication in the following form:

impaired.

     Section 17.13. Waiver of Jury Trial. EACH OF THE COMPANY AND THE TRUSTEE HEREBY IRREVOCABLY
WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN
ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS INDENTURE, THE NOTES OR THE TRANSACTION
CONTEMPLATED HEREBY.

     Section 17.14. Force Majeure. In no event shall the Trustee be responsible or liable for any
failure or delay in the performance of its obligations hereunder arising out of or caused by,
directly or indirectly, forces beyond its control, including, without limitation, strikes, work
stoppages, accidents, acts of war or terrorism, civil or military disturbances, nuclear or natural
catastrophes or acts of God, and interruptions, loss or malfunctions of utilities, communications
or computer (software and hardware) services; it being understood that the Trustee shall use
reasonable efforts that are consistent with accepted practices in the banking industry to resume
performance as soon as practicable under the circumstances.

     Section 17.15. Calculations. Except as otherwise provided herein, the Company shall be
responsible for making all calculations called for under the Notes. These calculations include,
but are not limited to, determinations of the Last Reported Sale Prices of the Common Stock,
accrued interest payable on the Notes and the Conversion Rate of the Notes. The Company shall make
all these calculations in good faith and, absent manifest error, the Company’s calculations shall
be final and binding on Holders. The Company shall provide a schedule of its calculations to each
of the Trustee and the Conversion Agent, and each of the Trustee and Conversion Agent is entitled
to rely conclusively upon the accuracy of the Company’s calculations without independent
verification. The Trustee will forward the Company’s calculations to any Holder upon the written
request of that Holder at the sole cost and expense of the Company.

     Section 17.16. USA PATRIOT Act. The parties hereto acknowledge that in accordance with
Section 326 of the USA PATRIOT Act, the Trustee, like all financial institutions and in order to
help fight the funding of terrorism and money laundering, is required to obtain, verify and record
information that identifies each person or legal entity that establishes a relationship or opens an
account with the Trustee. The parties to this Indenture agree that they will provide the Trustee
with such information as it may request in order for the Trustee to satisfy the requirements of the
USA PATRIOT Act.

[FORM OF REVERSE OF NOTE]

Integra LifeSciences Holdings Corporation

1.625% Convertible Senior Note due 2016

     This Note is one of a duly authorized issue of Notes of the Company, designated as its 1.625%
Convertible Senior Notes due 2016 (the “Notes”), initially limited to the aggregate principal
amount of $230,000,000, all issued or to be issued under and pursuant to an Indenture dated as of
June 15, 2011 (the “Indenture”), between the Company and Wells Fargo Bank, National Association
(the “Trustee”), to which Indenture and all indentures supplemental thereto reference is hereby
made for a description of the rights, limitations of rights, obligations, duties and immunities
thereunder of the Trustee, the Company and the Holders of the Notes. Additional Notes may be
issued in an unlimited aggregate principal amount, subject to certain conditions specified in the
Indenture. Capitalized terms used in this Note and not defined in this Note shall have the
respective meanings set forth in the Indenture.

     In the event of certain Events of Default (other than an Event of Default specified in Section
6.01(i) or Section 6.01(j) of the Indenture with respect to the Company or any of its Significant
Subsidiaries) shall have occurred and be continuing, the principal of, and interest on, all Notes
may be declared, by either the Trustee or Holders of at least 25% in aggregate principal amount of
the Notes then outstanding, and upon said declaration shall become, due and payable, in the manner,
with the effect and subject to the conditions and certain exceptions set forth in the Indenture.

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

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

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

A-6

 

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

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

     Upon the occurrence of a Fundamental Change, the Holder has the right, at such Holder’s
option, to require the Company to repurchase for cash all of such Holder’s Notes or any portion
thereof (in principal amounts of $1,000 or integral multiples thereof) on the Fundamental Change
Repurchase Date at a price equal to the Fundamental Change Repurchase Price.

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

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

Re: Base Warrants

     The purpose of this letter agreement (this “Confirmation”) is to confirm the terms and
conditions of the Warrants issued by Integra LifeSciences Holdings Corporation (“Company”) to
Wells Fargo Bank, National Association (“Dealer”) as of the Trade Date specified below (the
“Transaction”). This letter agreement constitutes a “Confirmation” as referred to in the ISDA
Master Agreement specified below. This Confirmation shall replace any previous agreements and
serve as the final documentation for the Transaction.

     The definitions and provisions contained in the 2002 ISDA Equity Derivatives Definitions (the
“Equity Definitions”), as published by the International Swaps and Derivatives Association, Inc.
(“ISDA”), are incorporated into this Confirmation. In the event of any inconsistency between the
Equity Definitions and this Confirmation, this Confirmation shall govern. The Transaction shall be
deemed to be a Share Option Transaction within the meaning set forth in the Equity Definitions.

     Each party is hereby advised, and each such party acknowledges, that the other party has
engaged in, or refrained from engaging in, substantial financial transactions and has taken other
material actions in reliance upon the parties’ entry into the Transaction to which this
Confirmation relates on the terms and conditions set forth below.

1. This Confirmation evidences a complete and binding agreement between Dealer and Company as to
the
terms of the Transaction to which this Confirmation relates. This Confirmation shall supplement,
form a part of, and be subject to an agreement in the form of the 2002 ISDA Master Agreement (the
“Agreement”) as if Dealer and Company had executed an agreement in such form (but without any
Schedule except for (i) the election of the laws of the State of New York as the governing law
(without reference to choice of law doctrine); (ii) the election that the “Cross Default”
provisions of Section 5(a)(vi) of the Agreement shall apply to both parties, provided that (a) the
phrase “or becoming capable at such time of being declared” shall be deleted from clause (1) of
such Section 5(a)(vi); (b) the following language shall be added to the end thereof:
“Notwithstanding the foregoing, a default under subsection (2) hereof shall not constitute an Event
of Default if (i) the default was caused solely by error or omission of an administrative or
operational nature; (ii) funds were available to enable the party to make the payment when due; and
(iii) the payment is made within two Local Business Days of such party’s receipt of written notice
of its failure to pay.”; (c) “Specified Indebtedness” will have the meaning specified in Section 14
of the Agreement, except that such term shall not include obligations in respect of deposits
received in the ordinary course of a party’s banking business; and (d) “Threshold Amount” means in
relation to Dealer, three percent (3%) of shareholders’ equity of Wells Fargo & Company (the
“Dealer Parent”) and in relation to Company, USD 25 million.)) on the Trade Date. In the event of
any inconsistency between provisions of that Agreement and this Confirmation, this Confirmation
will prevail for the purpose of the Transaction to which this Confirmation relates.

 

 

The parties hereby agree that no Transaction other than the Transaction to which this
Confirmation relates shall be governed by the Agreement.

	Expiration Dates:

	 	Each Scheduled Trading Day during the period from, and
including, the First Expiration Date to, but excluding, the
100th Scheduled Trading Day following the First
Expiration Date shall be an “Expiration Date” for a
number of Warrants equal to the Daily Number of
Warrants on such date; provided that, notwithstanding
anything to the contrary in the Equity Definitions, if any
such date is a Disrupted Day, the Calculation Agent shall
(i) make adjustments, if applicable, to the Daily Number
of Warrants or shall reduce such Daily Number of
Warrants to zero for which such day shall be an
Expiration Date and shall designate a Scheduled Trading
Day or a number of Scheduled Trading Days as the
Expiration Date(s) for the remaining Daily Number of
Warrants or a portion thereof for the originally scheduled
Expiration Date and (ii) if the Daily Number of Warrants

such Expiration Date has not occurred pursuant to this
clause as of the eighth Scheduled Trading Day following
the last scheduled Expiration Date under the Transaction,
the Calculation Agent shall have the right to declare such
Scheduled Trading Day to be the final Expiration Date
and the Calculation Agent shall determine its good faith
estimate of the fair market value for the Shares as of the
Valuation Time on that eighth Scheduled Trading Day or
on any subsequent Scheduled Trading Day, as the
Calculation Agent shall determine using commercially
reasonable means. Any Scheduled Trading Day on which,
as of the date hereof, the Exchange is scheduled to close
prior to its normal close of trading shall be deemed not to
be a Scheduled Trading Day; if a closure of the Exchange
prior to its normal close of trading on any Scheduled
Trading Day is scheduled following the date hereof, then
such Scheduled Trading Day shall be deemed to be a
Disrupted Day in full.
	 
	 	 
	First Expiration Date:

Day, the next following Scheduled Trading Day), subject

	Daily Number of Warrants:

	 	For any Expiration Date, the Number of Warrants that

such day), rounded down to the nearest whole number,
subject to adjustment pursuant to the provisos to
“Expiration Dates”.
	 
	 	 
	Automatic Exercise:

	 	Applicable; and means that for each Expiration Date, a
number of Warrants equal to the Daily Number of
Warrants (as adjusted pursuant to the terms hereof) for

3

 

	 	 	 

	 

	 	such Expiration Date will be deemed to be automatically
exercised at the Expiration Time on such Expiration Date.
	 
	 	 
	Market Disruption Event:

	 	Section 6.3(a)(ii) of the Equity Definitions is hereby
amended by replacing clauses (ii) and (iii) in their entirety
with “(ii) an Exchange Disruption, (iii) an Early Closure
or (iv) a Regulatory Disruption; in each case that the
Calculation Agent determines is material.”
	 
	 	 
	Regulatory Disruption:

	 	Any event that Dealer, in its discretion based on the
advice of counsel, determines makes it advisable with
regard to any legal, regulatory or self-regulatory
requirements or related policies and procedures, for
Dealer to refrain from or decrease any market activity in
connection with the Transaction. Dealer shall notify
Issuer as soon as reasonably practicable that a Regulatory
Disruption has occurred and the Expiration Dates affected
by it.

	 	Scheduled Closing Time; provided that if the principal
trading session is extended, the Calculation Agent shall

Settlement Terms.

	 	 	 

	Settlement Method Election:

following is hereby inserted after the words “apply to such
Transaction” in the seventh line of Section 7.1 of the Equity
Definitions:
	 
	 	 
	 

	 	“and, if Cash Settlement is elected, the percentage of
Company’s settlement obligations with respect to such
Transaction, which percentage shall be greater than 0% and
less than or equal to 100%, that shall be settled in cash (the
“Cash Percentage”);
	 
	 	 
	 

	 	(iii) Company’s election of Cash Settlement shall be deemed
to be a representation and warranty by Company that on the
date of such election (A) Company is not in possession of
any material non-public information regarding Company or
the Shares, (B) Company is electing Cash Settlement in good
faith and not as part of a plan or scheme to evade compliance
with the federal securities laws, and (C) the assets of
Company at their fair valuation exceed the liabilities of

as such debts mature and does not intend to, or does not
believe that it will, incur debt beyond its ability to pay as
such debts mature; (iv) the same election of settlement
method and Cash Percentage shall apply to all Expiration
Dates hereunder ; (v) if Company elects Cash Settlement and

4

or greater than 100%, then the notice delivered by Company
will be deemed to be ineffective and the Default Settlement
Method will be deemed applicable to such Transaction and
(vi) Company may elect a Cash Percentage only if no event
of default has occurred and is continuing under any
indebtedness of Company or its subsidiaries in an aggregate
principal amount of $100 million or more.
	 
	 	 
	Electing Party:

	 	Company

	 	0%; provided, however, that if Company (i) validly delivers
notice of Cash Settlement hereunder and (ii) in such notice
validly elects a Cash Percentage greater than 0% and less
than or equal to 100%, the Cash Percentage shall equal the
percentage specified as such in such notice.
	 
	 	 
	Net Share Settlement:

	 	On the relevant Settlement Date, Company shall deliver
to Dealer a number of Shares equal to the Share Delivery
Quantity for such Settlement Date to the account specified
hereto free of payment through the Clearance System and
pay to Dealer an amount of cash in USD the Fractional
Share Amount for such Settlement Date. For purposes of
determining any dividends or distributions payable in
respect of such Shares, Dealer shall be treated as the

such Shares or, if earlier, at 5:00 p.m. (New York City
time) on such Settlement Date.
	 
	 	 
	Share Delivery Quantity:

	 	For any Settlement Date, a number of Shares, as
calculated by the Calculation Agent, equal to the product
of (i) one minus the Cash Percentage, expressed as a
fraction, and (ii) the Net Share Settlement Amount for
such Settlement Date divided by the Settlement Price on
the Valuation Date for such Settlement Date, rounded
down to the nearest whole number (for any Settlement
Date, the fraction of a share eliminated by such rounding,
the “Share Fraction” for such Settlement Date).
	 
	 	 
	Fractional Share Amount:

	 	An amount of cash in USD equal to the product of (i) the
Share Fraction for such Settlement Date and (ii) the
Settlement Price on the Valuation Date for such
Settlement Date.
	 
	 	 
	Net Share Settlement Amount:

	 	For any Settlement Date, an amount equal to the product

exercised on the relevant Exercise Date, (ii) the Strike
Price Differential for the relevant Valuation Date and (iii)
the Warrant Entitlement.
	 
	 	 
	Cash Settlement:

	 	If Cash Settlement is applicable, then, on the relevant
Settlement Date, Company shall (i) pay to Dealer an amount
of cash in USD equal to sum of (A) the product of (x) the

5

 

	 	 	 

	 

	 	Cash Percentage and (y) the Net Share Settlement Amount
for such Settlement Date and (B) the Fractional Share
Amount, if any, for such Settlement Date and (ii) deliver to
Dealer a number of Shares equal to the Share Delivery
Quantity for such Settlement Date to the account specified
hereto free of payment through the Clearance System. The
provisions opposite Net Share Settlement above shall apply
to any Shares delivered pursuant to clause (ii) of the
immediately preceding sentence.
	 
	 	 
	Settlement Price:

	 	For any Valuation Date, the per Share volume-weighted
average price as displayed under the heading “Bloomberg
VWAP” on Bloomberg page IART <equity> AQR (or any
successor thereto) in respect of the period from the
scheduled opening time of the Exchange to the Scheduled
Closing Time on such Valuation Date (or if such
volume-weighted average price is unavailable, the market
value of one Share on such Valuation Date, as determined by
the Calculation Agent). Notwithstanding the foregoing, if
(i) any Expiration Date is a Disrupted Day and (ii) the
Calculation Agent determines that such Expiration Date
shall be an Expiration Date for fewer than the Daily Number
of Warrants, as described above, then the Settlement Price
for the relevant Valuation Date shall be the
volume-weighted average price per Share on such Valuation
Date on the Exchange, as determined by the Calculation
Agent based on such sources as it deems appropriate using a
volume-weighted methodology, for the portion of such
Valuation Date for which the Calculation Agent determines
there is no Market Disruption Event.
	 
	 	 
	Settlement Dates:

	 	As determined pursuant to Section 9.4 of the Equity
Definitions, subject to Section 9(k)(i) hereof.
	 
	 	 
	Other Applicable Provisions:

	 	If Net Share Settlement is applicable, the provisions of
Sections 9.1(c), 9.8, 9.9, 9.11 (as modified below), 9.12
and 10.5 of the Equity Definitions will be applicable as if
Physical Settlement were applicable.
	 
	 	 
	Representation and Agreement:

	 	Notwithstanding Section 9.11 of the Equity Definitions, the
parties acknowledge that any Shares delivered to Dealer may
be, upon delivery, subject to restrictions and limitations
arising from Company’s status as issuer of the Shares under
applicable securities laws.

	3.	 	Additional Terms applicable to
the Transaction.
	 
	 	 	Adjustments applicable to the Transaction:

	 	 	 

	Method of Adjustment:

	 	Calculation Agent Adjustment. For the avoidance of doubt,
in making any adjustments under the Equity Definitions, the
Calculation Agent may make adjustments, if any, to any one

Daily Number of Warrants and the Warrant Entitlement.
Notwithstanding the foregoing, any cash dividends or
distributions on the

6

 

	 	 	 

	 

	 	Shares, whether or not extraordinary, shall be governed
by Section 9(f) of this Confirmation in lieu of Article 10
or Section 11.2(c) of the Equity Definitions.

Extraordinary Events
applicable to the

	 	Section 12.1(i) of the Equity Definitions is hereby
amended (a) by deleting the text in clause (i) thereof in
its
entirety (including the word “and” following clause (i))
and replacing it with the phrase “publicly quoted, traded
or listed (or whose related depositary receipts are
publicly
quoted, traded or listed) on any of the New York Stock
Exchange, The NASDAQ Global Select Market or The
NASDAQ Global Market (or their respective successors)”
and (b) by inserting immediately prior to the period the
phrase “and (iii) of an entity or person organized under
the laws of the United States, any State thereof or the
District of Columbia that also becomes Company under
the Transaction following such Merger Event or Tender
Offer”.

Consequence of Merger Events:

	 	 	 

	Merger Event:

	 	Applicable; provided that if an event occurs that
constitutes both a Merger Event under Section 12.1(b) of
the Equity Definitions and an Additional Termination
Event under Section 9(h)(ii)(B) of this Confirmation,
Dealer may elect, in its commercially reasonable
judgment, whether the provisions of Section 12.1(b) of
the Equity Definitions or Section 9(h)(ii)(B) will apply.
	 
	 	 
	     Share-for-Share:

	 	Modified Calculation Agent Adjustment

	Tender Offer:

	 	Applicable; provided that if an event occurs that
constitutes both a Tender Offer under Section 12.1(d) of
the Equity Definitions and Additional Termination Event
under Section 9(h)(ii)(A) of this Confirmation, Dealer
may elect, in its commercially reasonable judgment,
whether the provisions of Section 12.3 of the Equity
Definitions or Section 9(h)(ii)(A) will apply.
	 
	 	 
	     Share-for-Share:

	 	Modified Calculation Agent Adjustment

	Announcement Event:

	 	If an Announcement Date occurs in respect of a Merger
Event or Tender Offer (such occurrence or any
subsequent announcement relating to the same subject
matter, an “Announcement Event”), then on the earliest
of the Expiration Date, Early Termination Date or other
date of cancellation (the “Announcement Event
Adjustment Date”) in respect of each Warrant, the
Calculation Agent will determine the economic effect on
such Warrant of the Announcement Event (regardless of
whether the Announcement Event actually results in a
Merger Event or Tender Offer, and taking into account
such factors as the Calculation Agent may determine,
including, without limitation, changes in volatility,
expected dividends, stock loan rate or liquidity relevant to
the Shares or the Transaction whether prior to or after the
Announcement Event or for any period of time, including,
without limitation, the period from the Announcement
Event to the relevant Announcement Event Adjustment
Date). If the Calculation Agent determines that such
economic effect on any Warrant is material, then on the
Announcement Event Adjustment Date for such Warrant,
the Calculation Agent shall make such adjustment to the
exercise, settlement, payment or any other terms of such
Warrant as the Calculation Agent determines in its
reasonable discretion is appropriate to account for such
economic effect, which adjustment shall be effective
immediately prior to the exercise, termination or
cancellation of such Warrant, as the case may be. For the
avoidance of doubt, if more than one Announcement
Event occurs before the Announcement Event Adjustment
Date, such adjustment shall take into account each such
Announcement Event.
	 
	 	 
	Announcement Date:

	 	The definition of “Announcement Date” in Section 12.1
of the Equity Definitions is hereby amended by (i)
replacing the words “a firm” with the word “any” in the
second and fourth lines thereof, (ii) replacing the word
“leads to the” with the words “, if completed, would lead
to a” in the third and the fifth lines thereof, (iii) replacing
the words “voting shares” with the word “Shares” in the
fifth line thereof, and (iv) inserting the words “by any

	8.	 	Representations and Warranties of Company.
	 
	 	 	Each of the representations and warranties of Company set forth in Section 3 of the Purchase
Agreement (the “Purchase Agreement”), dated as of June 9, 2011, between Company and the
representatives of the Initial Purchasers party thereto (the “Representatives”), is true and
correct and is hereby deemed to be repeated to Dealer as if set forth herein; provided that
no such representation or warranty, other than the representations and warranties set forth
in Sections 3(a), (b), (d) and (e) of the Purchase Agreement, may be the basis of an Event
of Default under Section 5(a)(iv) of the Agreement. Company hereby further represents and
warrants to Dealer on the date hereof, on and as of the Premium Payment Date and, in the
case of the representations in Section 8(d), at all times until termination of the
Transaction, that:

	 	(a)	 	Company has all necessary corporate power and authority to execute, deliver and
perform its obligations in respect of the Transaction; such execution, delivery and
performance have been duly authorized by all necessary corporate action on Company’s
part; and this Confirmation has been duly and validly executed and delivered by Company
and constitutes its valid and binding obligation, enforceable against Company in
accordance with its terms, subject to applicable bankruptcy, insolvency, fraudulent
conveyance, reorganization, moratorium and similar laws affecting creditors’ rights and
remedies generally, and subject, as to enforceability, to general principles of equity,
including principles of commercial reasonableness, good faith and fair dealing
(regardless of whether enforcement is sought in a proceeding at law or in equity) and
except that rights to indemnification and contribution hereunder may be limited by
federal or state securities laws or public policy relating thereto.
	 
	 	(b)	 	Neither the execution and delivery of this Confirmation nor the incurrence or
performance of obligations of Company hereunder will conflict with or result in a
breach of the certificate of incorporation or by-laws (or any equivalent documents) of
Company, or any applicable law or regulation, or any order, writ, injunction or decree
of any court or governmental authority or agency, or any agreement or instrument to
which Company or any of its subsidiaries is a party or by which Company or any of its
subsidiaries is bound or to which Company or any of its subsidiaries is subject, or
constitute a default under, or result in the creation of any lien under, any such
agreement or instrument.

11

 

	 	(c)	 	No consent, approval, authorization, or order of, or filing with, any
governmental agency or body or any court is required in connection with the
execution, delivery or performance by Company of this Confirmation, except such as
have been obtained or made and such as may be required under the Securities Act of
1933, as amended (the “Securities Act”) or state securities laws.
	 
	 	(d)	 	A number of Shares equal to the Maximum Number of Shares (as defined below)
(the “Warrant Shares”) have been reserved for issuance by all required corporate action
of Company. The Warrant Shares have been duly authorized and, when delivered against
payment therefor (which may include Net Share Settlement in lieu of cash) and otherwise
as contemplated by the terms of the Warrants following the exercise of the Warrants in
accordance with the terms and conditions of the Warrants, will be validly issued,
fully-paid and non-assessable, and the issuance of the Warrant Shares will not be
subject to any preemptive or similar rights.
	 
	 	(e)	 	Company is not and will not be required to register as an “investment company”
as such term is defined in the Investment Company Act of 1940, as amended.
	 
	 	(f)	 	Company is an “eligible contract participant” (as such term is defined in
Section 1a(12) of the Commodity Exchange Act, as amended, other than a person that is
an eligible contract participant under Section 1a(12)(C) of the Commodity Exchange
Act).
	 
	 	(g)	 	Each of Company and its officers and directors is not, on the date hereof, in
possession of any material non-public information with respect to Company or the
Shares.

	9.	 	Other Provisions.

	 	(a)	 	Opinions. Company shall deliver to Dealer an opinion of counsel, dated
as of the Trade Date, with respect to the matters set forth in Sections 8(a) through
(d) of this Confirmation. Delivery of such opinion to Dealer shall be a condition
precedent for the purpose of Section 2(a)(iii) of the Agreement with respect to each
obligation of Dealer under Section 2(a)(i) of the Agreement.
	 
	 	(b)	 	Repurchase Notices. Company shall, on any day on which Company effects
any repurchase of Shares, promptly give Dealer a written notice of such repurchase (a
“Repurchase Notice”) on such day if following such repurchase, the number of
outstanding Shares on such day, subject to any adjustments provided herein, is (i)
less than 24,264,547 (in the case of the first such notice) or (ii) thereafter more
than 3,192,382 less than the number of Shares included in the immediately preceding
Repurchase Notice. Company agrees to indemnify and hold harmless Dealer and its
affiliates and their respective officers, directors, employees, affiliates, advisors,
agents and controlling persons (each, an “Indemnified Person”) from and against any
and all losses (including losses relating to Dealer’s hedging activities as a
consequence of becoming, or of the risk of becoming, a Section 16 “insider”, including
without limitation, any forbearance from hedging activities or cessation of hedging
activities and any losses in connection therewith with respect to the Transaction),
claims, damages, judgments, liabilities and expenses (including reasonable attorney’s
fees), joint or several, that an Indemnified Person actually may become subject to, as
a result of Company’s failure to provide Dealer with a Repurchase Notice on the day
and in the manner specified in this paragraph, and to reimburse, within 30 days, upon
written request, each of such Indemnified Persons for any reasonable legal or other
expenses incurred in connection with investigating, preparing for, providing testimony
or other evidence in connection with or defending any of the foregoing. If any suit,
action, proceeding (including any governmental or regulatory investigation), claim or
demand shall be brought or asserted against the Indemnified Person, such Indemnified
Person shall promptly notify Company in writing, and Company, upon request of the
Indemnified Person, shall retain counsel reasonably satisfactory to the Indemnified
Person to represent the Indemnified Person and any others Company may designate in
such proceeding and shall pay the fees and expenses of such counsel related to such
proceeding. Company shall not be liable for any settlement of any proceeding effected
without its written consent, but if settled with such consent or if there be a final
judgment for the plaintiff, Company agrees to indemnify any Indemnified Person from
and against any loss or liability by reason of such settlement or judgment. Company
shall not, without the prior written consent of

12

 

	 	 	 	the Indemnified Person, effect any settlement of any pending or threatened proceeding in
respect of which any Indemnified Person is or could have been a party and indemnity could
have been sought hereunder by such Indemnified Person, unless such settlement includes an
unconditional release of such Indemnified Person from all liability on claims that are the
subject matter of such proceeding on terms reasonably satisfactory to such Indemnified
Person. If the indemnification provided for in this paragraph is unavailable to an
Indemnified Person or insufficient in respect of any losses, claims, damages or
liabilities referred to therein, then Company under such paragraph, in lieu of
indemnifying such Indemnified Person thereunder, shall contribute to the amount paid or
payable by such Indemnified Person as a result of such losses, claims, damages or
liabilities. The remedies provided for in this paragraph are not exclusive and shall not
limit any rights or remedies that may otherwise be available to any Indemnified Person at
law or in equity. The indemnity and contribution agreements contained in this paragraph
shall remain operative and in full force and effect regardless of the termination of the
Transaction.
	 
	 	(c)	 	Regulation M. Company is not on the Trade Date engaged in a distribution, as such
term is used in Regulation M under the Securities Exchange Act of 1934, as amended (the
“Exchange Act”), of any securities of Company, other than a distribution meeting the
requirements of the exception set forth in Rules 101(b)(10) and 102(b)(7) of Regulation M.
Company shall not, until the second Scheduled Trading Day immediately following the Effective
Date, engage in any such distribution.
	 
	 	(d)	 	No Manipulation. Company is not entering into the Transaction to create actual or
apparent trading activity in the Shares (or any security convertible into or exchangeable for
the Shares) or to raise or depress or otherwise manipulate the price of the Shares (or any
security convertible into or exchangeable for the Shares) or otherwise in violation of the
Exchange Act.
	 
	 	(e)	 	Transfer or Assignment. Company may not transfer any of its rights or obligations
under the Transaction without the prior written consent of Dealer. Dealer may, without
Company’s consent, transfer or assign all or any part of its rights or obligations under the
Transaction to any third party. If at any time at which (A) the Section 16 Percentage exceeds
7.5%, (B) the Warrant Equity Percentage exceeds 14.5%, or (C) the Share Amount exceeds the
Applicable Share Limit (if any applies) (any such condition described in clauses (A), (B) or
(C), an “Excess Ownership Position”), Dealer is unable after using its commercially
reasonable efforts to effect a transfer or assignment of Warrants to a third party on pricing
terms reasonably acceptable to Dealer and within a time period reasonably acceptable to
Dealer such that no Excess Ownership Position exists, then Dealer may designate any Exchange
Business Day as an Early Termination Date with respect to a portion of the Transaction (the
“Terminated Portion”), such that following such partial termination no Excess Ownership
Position exists. In the event that Dealer so designates an Early Termination Date with
respect to a Terminated Portion, a payment shall be made pursuant to Section 6 of the
Agreement as if (1) an Early Termination Date had been designated in respect of a Transaction
having terms identical to the Transaction and a Number of Warrants equal to the number of
Warrants underlying the Terminated Portion, (2) Company were the sole Affected Party with
respect to such partial termination and (3) the Terminated Portion were the sole Affected
Transaction (and, for the avoidance of doubt, the provisions of Section 9(j) shall apply to
any amount that is payable by Company to Dealer pursuant to this sentence as if Company was
not the Affected Party). The “Section 16 Percentage” as of any day is the fraction, expressed
as a percentage, (A) the numerator of which is the number of Shares that Dealer and each
person subject to aggregation of Shares with Dealer under Section 13 or Section 16 of the
Exchange Act and rules promulgated thereunder directly or indirectly beneficially own (as
defined under Section 13 or Section 16 of the Exchange Act and rules promulgated thereunder)
and (B) the denominator of which is the number of Shares outstanding. The “Warrant Equity
Percentage” as of any day is the fraction, expressed as a percentage, (A) the numerator of
which is the sum of (1) the product of the Number of Warrants and the Warrant Entitlement and
(2) the aggregate number of Shares underlying any other warrants purchased by Dealer from
Company, and (B) the denominator of which is the number of Shares outstanding. The “Share
Amount” as of any day is the number of Shares that Dealer and any person whose ownership
position would be aggregated with that of

13

 

	 	 	 	Dealer (Dealer or any such person, a “Dealer Person”) under any law, rule, regulation,
regulatory order or organizational documents or contracts of Company that are, in each
case, applicable to ownership of Shares (“Applicable Restrictions”), owns, beneficially
owns, constructively owns, controls, holds the power to vote or otherwise meets a relevant
definition of ownership under any Applicable Restriction, as determined by Dealer in its
reasonable discretion. The “Applicable Share Limit” means a number of Shares equal to (A)
the minimum number of Shares that could give rise to reporting or registration obligations
(except for any filings of Schedule 13D or Schedule 13G under the Exchange Act or any other
filing obligations applicable as of the date hereof) or other requirements (including
obtaining prior approval from any person or entity) of a Dealer Person, or could result in
an adverse effect on a Dealer Person, under any Applicable Restriction, as determined by
Dealer in its reasonable discretion, minus (B) 1% of the number of Shares outstanding.
Notwithstanding any other provision in this Confirmation to the contrary requiring or
allowing Dealer to purchase, sell, receive or deliver any Shares or other securities, or
make or receive any payment in cash, to or from Company, Dealer may designate any of its
affiliates to purchase, sell, receive or deliver such Shares or other securities, or make
or receive such payment in cash, and otherwise to perform Dealer’s obligations in respect
of the Transaction and any such designee may assume such obligations. Dealer shall be
discharged of its obligations to Company to the extent of any such performance.
	 
	 	(f)	 	Dividends. If at any time during the period from and including the Effective Date,
to and including the last Expiration Date, an ex-dividend date for a cash dividend occurs
with respect to the Shares (an “Ex-Dividend Date”), then the Calculation Agent will adjust
any of the Strike Price, Number of Warrants and/or Daily Number of Warrants to preserve the
fair value of the Warrants to Dealer after taking into account such dividend.
	 
	 	(g)	 	Terms Relating to Wells Fargo Securities, LLC (the “Agent”).

	 	(i)	 	The Agent is registered as a broker-dealer with the U.S. Securities and
Exchange Commission and the Financial Industry Regulatory Authority, is acting
hereunder for and on behalf of Dealer solely in its capacity as agent for Dealer
pursuant to instructions from Dealer, and is not and will not be acting as the
Company’s agent, broker, advisor or fiduciary in any respect under or in connection
with the Transaction.
	 
	 	(ii)	 	In addition to acting as Dealer’s agent in executing the Transaction, the
Agent is authorized from time to time to give written payment and/or delivery
instructions to Company directing it to make its payments and/or deliveries under the
Transaction to an account of the Agent for remittance to the Dealer (or its designee),
and for that purpose any such payment or delivery by Company to the Agent shall be
treated as a payment or delivery to the Dealer.
	 
	 	(iii)	 	Except as otherwise provided herein, any and all notices, demands, or
communications of any kind transmitted in writing by either Dealer or Company under or
in connection with the Transaction will be transmitted exclusively by such party to
the other party through the Agent at the following address:

	 	(iv)	 	The Agent shall have no responsibility or liability to the Dealer or Company

their respective obligations under or in connection with the Transaction, (ii) the
collection or enforcement of any such obligations, or (iii) the exercise of any of the
rights and remedies of either Dealer or Company under or in connection with the
Transaction. Each of Dealer and

14

 

	 	 	 	Company agrees to proceed solely against the other to collect or enforce any such
obligations, and the Agent shall have no liability in respect of the Transaction
except for its gross negligence or willful misconduct in performing its duties as
the agent of Dealer.
	 
	 	(v)	 	Upon written request, the Agent will furnish to Dealer and Company the date
and time of the execution of the Transaction and a statement as to the source and

	 	(ii)	 	Notwithstanding anything to the contrary in this Confirmation, upon the occurrence
of one of the following events, with respect to the Transaction, (1) Dealer shall have
the right to designate such event an Additional Termination Event and designate an Early
Termination Date pursuant to Section 6(b) of the Agreement, (2) Company shall be deemed
the sole Affected Party with respect to such Additional Termination Event and (3) the
Transaction shall be deemed the sole Affected Transaction:

	 	(A)	 	A “person” or “group” within the meaning of Section 13(d) of the Exchange
Act, other than Company, its subsidiaries and its and their employee benefit plans,
files a Schedule TO or any schedule, form or report under the Exchange Act disclosing
that such person or group has become the “beneficial owner,” as defined in Rule 13d-3
under the Exchange Act, of the common equity of Company representing more than 50% of
the voting power of such common equity.
	 
	 	(B)	 	The consummation of (I) any recapitalization, reclassification or change of
the Shares (other than changes resulting from a subdivision or combination) as a
result of which the Shares would be converted into, or exchanged for, stock, other
securities, other property or assets, (II) any share exchange, consolidation or
merger of Company pursuant to which the Shares will be converted into cash,
securities or other property, other than a merger of Company solely for the purpose
of changing Company’s jurisdiction of incorporation, that results in a
reclassification, conversion or exchange of then outstanding Shares solely into
            shares of common stock of the surviving entity, or (III) any sale, lease or other
transfer in one transaction or a series of transactions of all or substantially all
of the consolidated assets of Company and its subsidiaries, taken as a whole, to any
person other than one of Company’s subsidiaries; provided, however, that a
transaction described in clause (II) pursuant to which one or more holders of
Company’s common equity entitled to vote generally in elections of directors
immediately prior to such transaction have the entitlement to exercise, directly or
indirectly, 50% or more of the total voting power of all classes of Company’s common
equity entitled to vote generally in elections of directors of the continuing or
surviving person immediately after giving effect to such transaction shall not
constitute an Additional Termination Event pursuant to this clause (B).
	 
	 	(C)	 	Default by Company or any subsidiary of Company in the payment when due,
after the expiration of any applicable grace period, of principal of, or premium, if
any, or interest on, recourse indebtedness for money borrowed in the aggregate
principal amount then outstanding of $25.0 million or more, or acceleration of
Company’s or any subsidiary of Company’s recourse indebtedness for money borrowed in
the aggregate principal amount of $25.0 million or more so that it becomes due and
payable before the date on which it would otherwise have become due and payable, if
such default is not cured or waived, or such acceleration is not rescinded, as the
case may be.
	 
	 	(D)	 	A final judgment for the payment of $25.0 million or more (excluding any
amounts covered by insurance) rendered against Company or any of its subsidiaries,
which judgment is not discharged 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.
	 
	 	(E)	 	Dealer, despite using commercially reasonable efforts, is unable or
reasonably
determines that it is impractical or illegal, to hedge its exposure with respect
to
the Transaction in the public market without registration under the Securities

16

 

	 	 	 	Act or as a result of any legal, regulatory or self-regulatory
requirements or related policies and procedures (whether or not such
requirements, policies or procedures are imposed by law or have been
voluntarily adopted by Dealer).

Notwithstanding the foregoing, a transaction or transactions described in clauses
(A) or (B) above shall not constitute an Additional Termination Event if at least
90% of the consideration received or to be received by the holders of the Shares,
excluding cash payments for fractional shares and cash payments made in respect of
dissenters’ appraisal rights, in connection with such transaction or transactions
consists of shares of common stock, ordinary shares, American depositary receipts
or American depositary shares that are listed or quoted on any of The New York
Stock Exchange, The NASDAQ Global Select Market or The NASDAQ Global Market (or any
of their respective successors) or will be so listed or quoted when issued or
exchanged in connection with such transaction or transactions

	 	(i)	 	No Collateral or Set-off. Notwithstanding any provision of the Agreement or any
other agreement between the parties to the contrary, the obligations of Company hereunder are
not secured by any collateral. Each party waives any and all rights it may have to set off
obligations arising under the Agreement and the Transaction against other obligations between
the parties, whether arising under any other agreement, applicable law or otherwise.
	 
	 	(j)	 	Alternative Calculations and Payment on Early Termination and on Certain Extraordinary
Events. If, in respect of the Transaction, an amount is payable by Company to Dealer, (A)
pursuant to Section 12.7 or Section 12.9 of the Equity Definitions or (B) pursuant to Section
6(d)(ii) of the Agreement (any such amount, a “Payment Obligation”), Company shall have the
right, in its sole discretion, to satisfy the Payment Obligation by the Share Termination
Alternative (as defined below) (except that Company shall not have the right to make such an
election in the event of (I) a Nationalization, Insolvency, Merger Event or Tender Offer in
which the consideration to be paid to holders of Shares consists solely of cash, (II) a Merger
Event or Tender Offer that is within Company’s control, or (III) an Event of Default in which
Company is the Defaulting Party or a Termination Event in which Company is the Affected Party,
other than an Event of Default of the type described in Section 5(a)(iii), (v), (vi), (vii) or
(viii) of the Agreement or a Termination Event of the type described in Section 5(b) of the
Agreement, in each case that resulted from an event or events outside Company’s control) and
shall give irrevocable telephonic notice to Dealer, confirmed in writing within one Scheduled
Trading Day, no later than 5:00 p.m. (New York City time) on the Merger Date, Tender Offer
Date, Announcement Date (in the case of a Nationalization, Insolvency or Delisting), Early
Termination Date or date of cancellation, as applicable; provided that if Company does not
validly elect to satisfy the Payment Obligation by the Share Termination Alternative, Dealer
shall have the right to require Company to satisfy its Payment Obligation by the Share
Termination Alternative.

	 	 	 

	Share Termination Alternative:

	 	If applicable, Company shall deliver to Dealer the Share
Termination Delivery Property on the date (the “Share
Termination Payment Date”) on which the Payment
Obligation would otherwise be due pursuant to Section
12.7 or Section 12.9 of the Equity Definitions or Section
6(d)(ii) of the Agreement, as applicable, subject to
Section 9(k)(i) below, in satisfaction, subject to
Section 9(k)(ii) below, of the relevant Payment
Obligation, in the manner reasonably requested by Dealer
free of payment.
	 
	 	 
	Share Termination Delivery 

Property:

	 	A number of Share Termination Delivery Units, as calculated
by the Calculation Agent, equal to the relevant Payment
Obligation divided by the Share Termination Unit Price.
The Calculation Agent shall adjust the amount of Share

17

 

	 	 	 

	 

	 	Termination Delivery Property by replacing any fractional
portion of a security therein with an amount of cash
equal to the value of such fractional security based on
the values used to calculate the Share Termination Unit
Price (without giving effect to any discount pursuant to
Section 9(k)(i)).
	 
	 	 
	Share Termination Unit Price:

	 	The value to Dealer of property contained in one Share
Termination Delivery Unit on the date such Share
Termination Delivery Units are to be delivered as Share
Termination Delivery Property, as determined by the
Calculation Agent in its discretion by commercially
reasonable means. In the case of a Private Placement of
Share Termination Delivery Units that are Restricted
Shares (as defined below), as set forth in Section
9(k)(i) below, the Share Termination Unit Price shall be
determined by the discounted price applicable to such
Share Termination Delivery Units. In the case of a
Registration Settlement of Share Termination Delivery
Units that are Restricted Shares (as defined below) as
set forth in Section 9(k)(ii) below, the Share
Termination Unit Price shall be the Settlement Price on
the Merger Date, Tender Offer Date, Announcement Date (in
the case of a Nationalization, Insolvency or Delisting),
Early Termination Date or date of cancellation, as
applicable. The Calculation Agent shall notify Company of
the Share Termination Unit Price at the time of
notification of such Payment Obligation to Company or, if
applicable, at the time the discounted price applicable
to the relevant Share Termination Units is determined
pursuant to Section 9(k)(i).
	 
	 	 
	Share Termination Delivery Unit:

	 	In the case of a Termination Event, Event of Default
Additional Disruption Event or Delisting, one Share or,
in the case of Nationalization, Insolvency, Tender Offer
or Merger Event, a unit consisting of the number or
amount of each type of property received by a holder of
one Share (without consideration of any requirement to
pay cash or other consideration in lieu of fractional
amounts of any securities) in such Nationalization,
Insolvency, Tender Offer or Merger Event. If such
Nationalization, Insolvency, Tender Offer or Merger Event
involves a choice of consideration to be received by
holders, such holder shall be deemed to have elected to
receive the maximum possible amount of cash.
	 
	 	 
	Failure to Deliver:

	 	Inapplicable
	 
	 	 
	Other applicable provisions:

	 	If Share Alternative Termination is applicable, the
provisions
of Sections 9.1(c), 9.8, 9.9, 9.11 (as modified below),
9.12 and 10.5 of the Equity Definitions will be
applicable as if Physical Settlement were applicable.

	 	(k)	 	Registration/Private Placement Procedures. If, in the reasonable judgment of Dealer
based on the advice of counsel, following any delivery of Shares or Share Termination Delivery
Property to Dealer hereunder, such Shares or Share Termination Delivery Property would be in
the hands of Dealer subject to any applicable restrictions with respect to any registration or
qualification requirement or prospectus delivery requirement for such Shares or Share
Termination Delivery Property pursuant to any applicable federal or state securities law
(including, without limitation, any such requirement arising under Section 5 of the Securities
Act as a result of such Shares or

18

 

	 	 	 	Share Termination Delivery Property being “restricted securities”, as such term is defined in Rule
144 under the Securities Act, or as a result of the sale of such Shares or Share Termination
Delivery Property being subject to paragraph (c) of Rule 145 under the Securities Act) (such Shares
or Share Termination Delivery Property, “Restricted Shares”), then delivery of such Restricted
Shares shall be effected pursuant to either clause (i) or (ii) below at the election of Company,
unless Dealer waives the need for registration/private placement procedures set forth in (i) and
(ii) below. Notwithstanding the foregoing, solely in respect of any Daily Number of Warrants
exercised or deemed exercised on any Expiration Date, Company shall elect, prior to the first
Settlement Date for the First Expiration Date, a Private Placement Settlement or Registration
Settlement for all deliveries of Restricted Shares for all such Expiration Dates which election
shall be applicable to all Settlement Dates for such Warrants and the procedures in clause (i) or
clause (ii) below shall apply for all such delivered Restricted Shares on an aggregate basis
commencing after the final Settlement Date for such Warrants. The Calculation Agent shall make
reasonable adjustments to settlement terms and provisions under this Confirmation to reflect a
single Private Placement or Registration Settlement for such aggregate Restricted Shares delivered
hereunder.

	 	(i)	 	If Company elects to settle the Transaction pursuant to this clause (i) (a “Private Placement
Settlement”), then delivery of Restricted Shares by Company shall be effected in accordance
with customary private placement procedures for placements of equity securities of
substantially similar size reasonably acceptable to Dealer; provided that Company may not
elect a Private Placement Settlement if, on the date of its election, it has taken, or caused
to be taken, any action that would make unavailable either the exemption pursuant to Section
4(2) of the Securities Act for the sale by Company to Dealer (or any affiliate designated by
Dealer) of the Restricted Shares or the exemption pursuant to Section 4(1) or Section 4(3) of
the Securities Act for resales of the Restricted Shares by Dealer (or any such affiliate of
Dealer). The Private Placement Settlement of such Restricted Shares shall include customary
representations, covenants, blue sky and other governmental filings and/or registrations,
indemnities to Dealer, due diligence rights (for Dealer or any designated buyer of the
Restricted Shares by Dealer), opinions and certificates, and such other documentation as is
customary for private placements of equity securities of substantially similar size, all
reasonably acceptable to Dealer. In the case of a Private Placement Settlement, Dealer shall
determine the appropriate discount to the Share Termination Unit Price (in the case of
settlement of Share Termination Delivery Units pursuant to Section 9(j) above) or any
Settlement Price (in the case of settlement of Shares pursuant to Section 2 above) applicable
to such Restricted Shares in a commercially reasonable manner and appropriately adjust the
number of such Restricted Shares to be delivered to Dealer hereunder. Notwithstanding the
Agreement or this Confirmation, the date of delivery of such Restricted Shares shall be the
Exchange Business Day following notice by Dealer to Company, of such applicable discount and
the number of Restricted Shares to be delivered pursuant to this clause (i). For the avoidance
of doubt, delivery of Restricted Shares shall be due as set forth in the previous sentence and
not be due on the Share Termination Payment Date (in the case of settlement of Share
Termination Delivery Units pursuant to Section 9(j) above) or on the Settlement Date for such
Restricted Shares (in the case of settlement in Shares pursuant to Section 2 above).
	 
	 	(ii)	 	If Company elects to settle the Transaction pursuant to this clause (ii) (a “Registration
Settlement”), then Company shall promptly (but in any event no later than the beginning of
the Resale Period) file and use its reasonable best efforts to make effective under the
Securities Act a registration statement or supplement or amend an outstanding registration
statement in form and substance reasonably satisfactory to Dealer, to cover the resale of
such Restricted Shares in accordance with customary resale registration procedures, including
covenants, conditions, representations, underwriting discounts (if applicable), commissions
(if applicable), indemnities due diligence rights, opinions and certificates, and such other
documentation as is customary in underwriting agreements for equity resales of substantially
similar size, all reasonably acceptable to Dealer. If Dealer,

19

 

	 	 	 	in its reasonable discretion, is not satisfied with such procedures and
documentation Private Placement Settlement shall apply. If Dealer is satisfied with
such procedures and documentation, it shall sell the Restricted Shares pursuant to
such registration statement during a period (the “Resale Period”) commencing on the
Exchange Business Day following delivery of such Restricted Shares (which, for the
avoidance of doubt, shall be (x) the Share Termination Payment Date in case of
settlement in Share Termination Delivery Units pursuant to Section 9(j) above or
(y) the Settlement Date in respect of the final Expiration Date for all Daily
Number of Warrants) and ending on the earliest of (i) the Exchange Business Day on
which Dealer completes the sale of all Restricted Shares or, in the case of
settlement of Share Termination Delivery Units, a sufficient number of Restricted
Shares so that the realized net proceeds of such sales equals or exceeds the
Payment Obligation (as defined above), (ii) the date upon which all Restricted
Shares have been sold or transferred pursuant to Rule 144 (or similar provisions
then in force) or Rule 145(d)(2) (or any similar provision then in force) under the
Securities Act and (iii) the date upon which all Restricted Shares may be sold or
transferred by a non-affiliate pursuant to Rule 144 (or any similar provision then
in force) or Rule 145(d)(2) (or any similar provision then in force) under the
Securities Act. If the Payment Obligation exceeds the realized net proceeds from
such resale, Company shall transfer to Dealer by the open of the regular trading
session on the Exchange on the Exchange Trading Day immediately following the last
day of the Resale Period the amount of such excess (the “Additional Amount”) in
cash or in a number of Shares (“Make-whole Shares”) in an amount that, based on the
Settlement Price on the last day of the Resale Period (as if such day was the
“Valuation Date” for purposes of computing such Settlement Price), has a dollar
value equal to the Additional Amount. The Resale Period shall continue to enable
the sale of the Make-whole Shares. If Company elects to pay the Additional Amount
in Shares, the requirements and provisions for Registration Settlement shall apply.
This provision shall be applied successively until the Additional Amount is equal
to zero. In no event shall Company deliver a number of Restricted Shares greater
than the Maximum Number of Shares.
	 
	 	(iii)	 	Without limiting the generality of the foregoing, Company agrees that any
Restricted Shares delivered to Dealer, as purchaser of such Restricted Shares, (A)
may be transferred by and among Dealer and its affiliates and Company shall effect
such transfer without any further action by Dealer and (B) after the period of 6
months from the Trade Date (or 1 year from the Trade Date if, at such time,
informational requirements of Rule 144(c) under the Securities Act are not satisfied
with respect to Company) has elapsed after any Settlement Date or Share Termination
Payment Date, as applicable, for such Restricted Shares, Company shall promptly
remove, or cause the transfer agent for such Restricted Shares to remove, any legends
referring to any such restrictions or requirements from such Restricted Shares upon
request by Dealer (or such affiliate of Dealer) to Company or such transfer agent,
without any requirement for the delivery of any certificate, consent, agreement,
opinion of counsel, notice or any other document, any transfer tax stamps or payment
of any other amount or any other action by Dealer (or such affiliate of Dealer).
	 
	 	(iv)	 	If the Private Placement Settlement or the Registration Settlement shall not
be effected as set forth in clauses (i) or (ii), as applicable, then failure to
effect such Private Placement Settlement or such Registration Settlement shall
constitute an Event of Default with respect to which Company shall be the Defaulting
Party.

	 	(l)	 	Limit on Beneficial Ownership. Notwithstanding any other provisions hereof, Dealer
may not exercise any Warrant hereunder or be entitled to take delivery of any Shares
deliverable hereunder, and Automatic Exercise shall not apply with respect to any Warrant
hereunder, to the extent (but only to the extent) that, after such receipt of any Shares upon
the exercise of such Warrant or otherwise hereunder, (i) the Section 16 Percentage would
exceed 7.5%, or (ii) the Share Amount would exceed the Applicable Share Limit. Any purported
delivery hereunder shall

20

 

	 	 	 	be void and have no effect to the extent (but only to the extent) that, after such
delivery, (i) the Section 16 Percentage would exceed 7.5%, or (ii) the Share Amount would
exceed the Applicable Share Limit. If any delivery owed to Dealer hereunder is not made, in
whole or in part, as a result of this provision, Company’s obligation to make such delivery
shall not be extinguished and Company shall make such delivery as promptly as practicable
after, but in no event later than one Business Day after, Dealer gives notice to Company
that, after such delivery, (i) the Section 16 Percentage would not exceed 7.5%, and (ii)
the Share Amount would not exceed the Applicable Share Limit.
	 
	 	(m)	 	Share Deliveries. Company acknowledges and agrees that, to the extent the holder of
this Warrant is not then an affiliate and has not been an affiliate for 90 days (it being
understood that Dealer will not be considered an affiliate under this paragraph solely by
reason of its receipt of Shares pursuant to the Transaction), and otherwise satisfies all
holding period and other requirements of Rule 144 of the Securities Act applicable to it, any
delivery of Shares or Share Termination Delivery Property hereunder at any time after 6 months
from the Trade Date (or 1 year from the Trade Date if, at such time, informational
requirements of Rule 144(c) are not satisfied with respect to Company) shall be eligible for
resale under Rule 144 of the Securities Act and Company agrees to promptly remove, or cause
the transfer agent for such Shares or Share Termination Delivery Property, to remove, any
legends referring to any restrictions on resale under the Securities Act from the Shares or
Share Termination Delivery Property. Company further agrees that any delivery of Shares or
Share Termination Delivery Property prior to the date that is 6 months from the Trade Date (or
1 year from the Trade Date if, at such time, informational requirements of Rule 144(c) are not
satisfied with respect to Company), may be transferred by and among Dealer and its affiliates
and Company shall effect such transfer without any further action by Dealer. Notwithstanding
anything to the contrary herein, Company agrees that any delivery of Shares or Share
Termination Delivery Property shall be effected by book-entry transfer through the facilities
of DTC, or any successor depositary, if at the time of delivery, such class of Shares or class
of Share Termination Delivery Property is in book-entry form at DTC or such successor
depositary. Notwithstanding anything to the contrary herein, to the extent the provisions of
Rule 144 of the Securities Act or any successor rule are amended, or the applicable
interpretation thereof by the Securities and Exchange Commission or any court change after the
Trade Date, the agreements of Company herein shall be deemed modified to the extent necessary,
in the opinion of outside counsel of Company, to comply with Rule 144 of the Securities Act,
as in effect at the time of delivery of the relevant Shares or Share Termination Delivery
Property.
	 
	 	(n)	 	Waiver of Jury Trial. Each party waives, to the fullest extent permitted by
applicable law, any right it may have to a trial by jury in respect of any suit, action or
proceeding relating to the Transaction. Each party (i) certifies that no representative, agent
or attorney of the other party has represented, expressly or otherwise, that such other party
would not, in the event of such a suit, action or proceeding, seek to enforce the foregoing
waiver and (ii) acknowledges that it and the other party have been induced to enter into the
Transaction, as applicable, by, among other things, the mutual waivers and certifications
provided herein.
	 
	 	(o)	 	Tax Disclosure. Effective from the date of commencement of discussions concerning the
Transaction, Company and each of its employees, representatives, or other agents may disclose
to any and all persons, without limitation of any kind, the tax treatment and tax structure of
the Transaction and all materials of any kind (including opinions or other tax analyses) that
are provided to Company relating to such tax treatment and tax structure.
	 
	 	(p)	 	Maximum Share Delivery.

	 	(i)	 	Notwithstanding any other provision of this Confirmation, the Agreement or
the Equity Definitions, in no event will Company at any time be required to deliver a
number of Shares greater than two times the Number of Shares (the “Maximum Number of
Shares”) to Dealer in connection with the Transaction.

21

 

	 	(ii)	 	In the event Company shall not have delivered to Dealer the full number of
Shares or Restricted Shares otherwise deliverable by Company to Dealer pursuant to
the terms of the Transaction because Company has insufficient authorized but
unissued Shares (such deficit, the “Deficit Shares”), Company shall be continually
obligated to deliver, from time to time, Shares or Restricted Shares, as the case
may be, to Dealer until the full number of Deficit Shares have been delivered
pursuant to this Section 9(p)(ii), when, and to the extent that, (A) Shares are
repurchased, acquired or otherwise received by Company or any of its subsidiaries
after the Trade Date (whether or not in exchange for cash, fair value or any other
consideration), (B) authorized and unissued Shares reserved for issuance in
respect of other transactions prior to such date that prior to the relevant date
become no longer so reserved or (C) Company additionally authorizes any unissued
Shares that are not reserved for other transactions; provided that in no event
shall Company deliver any Shares or Restricted Shares to Dealer pursuant to this
Section 9(p)(ii) to the extent that such delivery would cause the aggregate number
of Shares and Restricted Shares delivered to Dealer to exceed the Maximum Number
of Shares. Company shall immediately notify Dealer of the occurrence of any of the
foregoing events (including the number of Shares subject to clause (A), (B) or (C)
and the corresponding number of Shares or Restricted Shares, as the case may be,
to be delivered) and promptly deliver such Shares or Restricted Shares, as the
case may be, thereafter.

	 	(q)	 	Right to Extend. Dealer may postpone, in whole or in part, any Expiration Date or any
other date of valuation or delivery with respect to some or all of the relevant Warrants (in
which event the Calculation Agent shall make appropriate adjustments to the Daily Number of
Warrants with respect to one or more Expiration Dates) if Dealer determines, in its
commercially reasonable judgment based on the advice of counsel, that such extension is
reasonably necessary or advisable to preserve Dealer’s hedging or hedge unwind activity
hereunder in light of existing liquidity conditions or to enable Dealer to effect purchases of
Shares in connection with its hedging, hedge unwind or settlement activity hereunder in a
manner that would, if Dealer were Issuer or an affiliated purchaser of Issuer, be in
compliance with applicable legal, regulatory or self-regulatory requirements, or with related
policies and procedures applicable to Dealer.
	 
	 	(r)	 	Status of Claims in Bankruptcy. Dealer acknowledges and agrees that this Confirmation
is not intended to convey to Dealer rights against Company with respect to the Transaction
that are senior to the claims of common stockholders of Company in any United States
bankruptcy proceedings of Company; provided that nothing herein shall limit or shall be deemed
to limit Dealer’s right to pursue remedies in the event of a breach by Company of its
obligations and agreements with respect to the Transaction; provided, further, that nothing
herein shall limit or shall be deemed to limit Dealer’s rights in respect of any transactions
other than the Transaction.
	 
	 	(s)	 	Securities Contract; Swap Agreement. The parties hereto intend for (i) the
Transaction to be a “securities contract” and a “swap agreement” as defined in the Bankruptcy
Code (Title 11 of the United States Code) (the “Bankruptcy Code”), and the parties hereto to
be entitled to the protections afforded by, among other Sections, Sections 362(b)(6),
362(b)(17), 546(e), 546(g), 555 and 560 of the Bankruptcy Code, (ii) a party’s right to
liquidate the Transaction and to exercise any other remedies upon the occurrence of any Event
of Default under the Agreement with respect to the other party to constitute a “contractual
right” as described in the Bankruptcy Code, and (iii) each payment and delivery of cash,
securities or other property hereunder to constitute a “margin payment” or “settlement
payment” and a “transfer” as defined in the Bankruptcy Code.
	 
	 	(t)	 	Wall Street Transparency and Accountability Act. In connection with Section 739 of
the Wall Street Transparency and Accountability Act of 2010 (“WSTAA”), the parties hereby
agree that neither the enactment of WSTAA or any regulation under the WSTAA, nor any
requirement under WSTAA or an amendment made by WSTAA, shall limit or otherwise impair either
party’s otherwise applicable rights to terminate, renegotiate, modify, amend or supplement
this Confirmation or the Agreement, as applicable, arising from a termination event, force
majeure,

22

 

	 	 	 	illegality, increased costs, regulatory change or similar event under this Confirmation,
the Equity Definitions incorporated herein, or the Agreement (including, but not limited
to, rights arising from Change in Law, Hedging Disruption, Increased Cost of Hedging, an
Excess Ownership Position, or Illegality (as defined in the Agreement)).
	 
	 	(u)	 	Early Unwind. In the event the sale of the “Underwritten Securities” (as defined in
the Purchase Agreement) is not consummated with the Representatives for any reason, or Company
fails to deliver to Dealer opinions of counsel as required pursuant to Section 9(a), in each
case by 5:00 p.m. (New York City time) on the Premium Payment Date, or such later date as
agreed upon by the parties (the Premium Payment Date or such later date the “Early Unwind
Date”), the Transaction shall automatically terminate (the “Early Unwind”), on the Early
Unwind Date and (i) the Transaction and all of the respective rights and obligations of Dealer
and Company under the Transaction shall be cancelled and terminated and (ii) each party shall
be released and discharged by the other party from and agrees not to make any claim against
the other party with respect to any obligations or liabilities of the other party arising out
of and to be performed in connection with the Transaction either prior to or after the Early
Unwind Date; provided that, other than in cases involving a breach of the Purchase Agreement
by Dealer, Company shall purchase from Dealer on the Early Unwind Date all Shares purchased by
Dealer or one or more of its affiliates in connection with the Transaction at the then
prevailing market price. Each of Dealer and Company represents and acknowledges to the other
that, subject to the proviso included in this Section 9(u), upon an Early Unwind, all
obligations with respect to the Transaction shall be deemed fully and finally discharged.
	 
	 	(v)	 	Payment by Dealer. In the event that (i) an Early Termination Date occurs or is
designated with respect to the Transaction as a result of a Termination Event or an Event of
Default (other than an Event of Default arising under Section 5(a)(ii) or 5(a)(iv) of the
Agreement) and, as a result, Dealer owes to Company an amount calculated under Section 6(e) of
the Agreement, or (ii) Dealer owes to Company, pursuant to Section 12.7 or Section 12.9 of the
Equity Definitions, an amount calculated under Section 12.8 of the Equity Definitions, such
amount shall be deemed to be zero.
