Exhibit 10.2

PLEDGE OF SHARES

This pledge of shares (the “Pledge of Shares”) has been entered into on this 28th May
2008 between:

	(1)	 	Trico Shipping AS, a Norwegian limited company registered with company registration number
976 854 020 with its registered address at 6090 Fosnavåg, Norway (the “Pledgor”); and
	 
	(2)	 	Carnegie Investment Bank AB Norway Brach, with company registration number 976 928 989 with
its registered address Stranden 1, Aker Brygge, 0250 Oslo, Norway (the “Pledgee”).
	 
	1.	 	The Share Pledge
	 
	1.1	 	To secure the payment and the discharge of the Pledgor’s obligations under the credit
facility agreement dated 28 May 2008 (the “Credit Facility”), entered into between the Pledgor
as borrower and the Pledgee as lender, the Pledgor hereby pledges on first priority to and
with the Pledgee the 58,428,955 shares of NOK 0.50 each, issued in the capital of Deep Ocean
ASA (the “Target Company”), representing 54.027 % of the shares issued in that company (the
(“Shares”), together with payment of dividends on the Shares and all other monies related to
the Shares or the sale thereof.
	 
	1.2	 	The aggregate maximum amount of the pledge created hereby shall be NOK 260,000,000 plus
interest, costs and expenses.
	 
	1.3	 	The Pledgor shall, subject to clause 2.5, have the right to vote for the Shares at any
general meeting of the Target Company.
	 
	1.4	 	In the event of an event of default under the Credit Facility which is continuing, the
Pledgee has the right to collect and use for its protection dividends and payments that
otherwise fall due in respect of the Shares.
	 
	1.5	 	In the event that a default occurs under the Credit Facility and is continuing, the Pledgee
shall have the right to enforce this Pledge of Shares in any manner legally available to it,
hereunder (i) immediately acquire ownership and title to all or any of the Shares, as provided
for in the Financial Collateral Act (17/2004); and (ii) immediately sell, assign or convert
into money by private or public sale or auction or in such other manner and on such terms as
the Pledgee in its sole discretion deems appropriate, all or any of the Shares, as provided
for in the Financial Collateral Act (17/2004).
	 
	1.6	 	Upon any sale of the Shares the Pledgee may apply the net sales proceeds towards interest,
principal and any other amount due to the Lenders under the Credit Facility in such order as
decided by it. Any Shares acquired by the Pledgee shall be the undivided property of the
Pledgee and any right, gain or loss on such Shares shall be for the sole account of the
Pledgee.
	 
	1.7	 	The pledge over the Shares evidenced by this Pledge of Shares shall immediately be discharged
when all amounts outstanding under the Credit Facility have been repaid in full.

 

 

	2.	 	Representations and warranties
	 
	2.1	 	The Pledgor represents and warrants that it is the legal and beneficial owner of the Shares,
and that they are free and clear of any lien, security interest, restriction on transfer,
option or other charge or encumbrance, and that it has full right and power to transfer the
relevant Shares to the Pledgee, free and clear of any interests described herein.
	 
	2.2	 	Upon execution of this Pledge of Shares the Pledgor (or the Pledgee if it elects to do so)
shall notify the Target Company of the pledge over the Shares (in a notice in the form and
content as set out in Appendix 1a hereto) and arrange for the registration of this
Pledge on the VPS account of the Borrower and cause the VPS account operator of such VPS
account to confirm such registration in writing to the Pledgee (in an acknowledgement in the
form and content as set out in Appendix 1b hereto).
	 
	2.3	 	The Pledgor shall, at his expense, promptly execute and deliver all further instruments and
documents, and take all further action, as may be reasonably requested by the Pledgee in order
to perfect and protect any security interest granted hereby or to enable the Pledgee to
exercise and enforce its rights and remedies hereunder with respect to the Shares.
	 
	2.4	 	The Pledgor shall not sell or transfer or grant any option to purchase any of the Shares or
subject any of the Shares to any further charge or encumbrance whatsoever without the prior
written consent of the Pledgee.
	 
	2.5	 	In respect of any proposal for an increase or decrease in share capital or any other
reorganization of the share capital or share classes in the Target Company (including but not
limited to motions for existing shareholders to waive their first right to subscribe new
shares) or any other issue which may have a material impact on the market value of the Shares
the Pledgor shall vote in accordance with the instructions of the Pledgee. For purposes of
clarification, making an intercompany loan from the Target Company or any of its affiliates to
Pledgor or any of its affiliates shall not be considered to materially impact the market value
of the Shares. The Target Company is currently a public limited company listed on Oslo Børs
and the Shares are registered with the VPS. In consideration of the circumstances of the
acquisition of the Target Company it is acknowledged that the Borrower may cause the Target
Company to become delisted from Oslo Børs, to be converted into a private limited company and
its share to become de-registered from the VPS. In the event the shares of the Target Company
is de-registered from the VPS, the Pledgor undertakes to give any notice and to take any other
action to perfect the Pledge (including but not limited to ensuring that the Pledge is duly
registered in the share register of the Target Company) and further the Pledgor hereby
irrevocably authorises the Pledgee to give any notice to the Target Company and to take any
other necessary actions on behalf of the Pledgor to implement any measures to perfect the
Pledge.
	 
	2.6	 	In the event of a sale the Pledgor hereby irrevocably waive any right of pre-emption in
respect of the Shares which they may have according to articles of association or otherwise.
	 
	3.	 	Miscellaneous
	 
	3.1	 	This Pledge of Shares shall be governed by and construed in accordance with Norwegian law.
	 
	3.2	 	Any action or proceeding against the Pledgee under this Pledge of Shares or in connection
thereof may be brought and enforced in the courts in the City of Oslo as the exclusive legal
venue.

     “Stated Maturity”, when used with respect to any Security or any installment of Interest
thereon, means the date specified in such Security as the fixed date on which the principal of such
Security or such installment of Interest is due and payable.

     “Stock Price” means the price paid per share of Common Stock in connection with a Make-Whole
Fundamental Change pursuant to which Additional Shares shall be added to the Conversion Rate as set
forth in Article 12, which shall be equal to (i) if holders of Common Stock receive only
cash consideration for their shares of Common Stock (in a single per-share

12

 

amount, other than with respect to appraisal and similar rights) in connection with such
Make-Whole Fundamental Change, the cash amount paid per share of Common Stock in such Make-Whole
Fundamental Change and (ii) in all other cases, the average of the Last Reported Sale Prices of the
Common Stock for the ten consecutive Trading Day period ending on, and including, the Trading Day
preceding the date on which such Make-Whole Fundamental Change occurs or becomes effective.

     “Subsidiary” means a corporation more than 50% of the outstanding voting stock of which is
owned, directly or indirectly, by the Company or by one or more other Subsidiaries, or by the
Company and one or more other Subsidiaries. For the purposes of this definition, “voting stock”
means stock which ordinarily has voting power for the election of directors, or persons performing
similar functions, whether at all times or only so long as no senior class of stock has such voting
power by reason of any contingency.

     “Successor” has the meaning specified in Section 8.01.

     “Trading Day” means a day during which (i) trading in the Common Stock generally occurs and

million in Original Principal Amount of such Securities at approximately 3:30 p.m., New York City
time, on such determination date from three independent nationally recognized securities dealers
selected by the Company, which may include any or all of the Initial Purchasers; provided that if
three such bids cannot reasonably be obtained, but two such bids are obtained, then the average of
the two bids will be used, and if only one such bid is obtained, that one bid shall be used. If at
least one bid for $2.0 million in Original Principal Amount of the Securities cannot reasonably be
obtained, then the Trading Price per $1,000 in Original Principal Amount of Securities shall be
deemed to be less than 98% of the product of the Last Reported Sale Price of the Common Stock and
the applicable Conversion Rate in effect on such date of determination. Any such determination
shall be conclusive absent manifest error. Notwithstanding the foregoing, for purposes of
Section 3.03 only, if two bids for $2.0 million in Original Principal Amount of the
Securities cannot reasonably be obtained from nationally recognized securities dealers selected by
the Company, but one such bid can reasonably be obtained, this one bid shall be used. If at least
one bid for $2.0 million in Original Principal Amount of the Securities cannot reasonably be
obtained from a nationally recognized securities dealer or in the Company’s reasonable judgment the
bid quotations are not indicative of the secondary market value of the Securities, then the Trading
Price of the Securities on a Trading Day will be deemed to equal the product of (x) the Conversion
Rate then in effect and (y) the closing sale price of the Common Stock on such Trading Day.

     “Trading Price Condition” has the meaning specified in Section 12.01.

     “Trigger Event” has the meaning specified in Section 12.05(c).

     “Trust Indenture Act” means the U.S. Trust Indenture Act of 1939 as in force at the date as of

required by any such amendment, the Trust Indenture Act of 1939 as so amended.

     “Trustee” means the Person named as the “Trustee” in the first paragraph of this Indenture
until a successor Trustee shall have become such pursuant to the applicable provisions of this
Indenture, and thereafter “Trustee” shall mean such successor Trustee.

     “U.S. Citizen” means a “U.S. Citizen” as defined in the Company’s Certificate of Incorporation
or other charter documents and any other person who is a “citizen of the United States” under the
Jones Act, Title 46 U.S.C. §§ 50101 et seq., and the rules and regulations thereunder.

     “Vice President,” when used with respect to the Company or the Trustee, means any vice
president, whether or not designated by a number or a word or words added before or after the title
“vice president”.

     “VWAP Market Disruption Event” means (i) a failure by the principal U.S. national or regional
securities exchange or market on which the Common Stock is listed or admitted to trading to open
for trading during its regular trading session or (ii) the occurrence or existence prior to 1:00

stating that all conditions precedent, if any, provided for in this Indenture relating to the
proposed action have been complied with and an Opinion of Counsel stating that in the opinion of
such counsel all such conditions precedent have been complied with.

     Every certificate or opinion with respect to compliance with a condition or covenant provided
for in this Indenture shall include:

     (1) a statement that each individual signing such certificate or opinion has read such
covenant or condition and the definitions herein relating thereto;

     (2) a brief statement as to the nature and scope of the examination or investigation upon
which the statements or opinions contained in such certificate or opinion are based;

     (3) a statement that, in the opinion of each such individual, he has made such examination or
investigation as is necessary to enable him to express an informed opinion as to whether or not
such covenant or condition has been complied with; and

     (4) a statement as to whether, in the opinion of each such individual, such condition or
covenant has been complied with.

     Section 1.03. Form of Documents Delivered to Trustee.

     In any case where several matters are required to be certified by, or covered by an opinion
of, any specified Person, it is not necessary that all such matters be certified by, or covered by
the opinion of, only one such Person, or that they be so certified or covered by only one document,
but one such Person may certify or give an opinion with respect to some matters and one or more
other such Persons as to other matters, and any such Person may certify or give an opinion as to
such matters in one or several documents.

     Any certificate or opinion of an officer of the Company may be based, insofar as it relates to
legal matters, upon a certificate or opinion of, or representations by, counsel (who may be an
employee of the Company), unless such officer knows, or in the exercise of reasonable care should
know, that the certificate or opinion or representations with respect to the matters upon which his
certificate or opinion is based are erroneous. Any such certificate or opinion of counsel may be
based, insofar as it relates to factual matters, upon a certificate or opinion of, or
representations by, an officer or officers of the Company stating that the information with respect
to such factual matters is in the possession of the Company, unless such counsel knows, or in the
exercise of reasonable care should know, that the certificate or opinion or representations with
respect to such matters are erroneous. Any such certificate or opinion of counsel may be based,
insofar as it relates to accounting matters, upon a certificate or opinion of, or representations
by, an accountant (who may be an employee of the Company) or firm of accountants, unless such
counsel knows, or in the exercise of reasonable care should know, that the certificate or opinion
or representations with respect to such matters are erroneous.

15

 

     Where any Person is required to make, give or execute two or more applications, requests,
consents, certificates, statements, opinions or other instruments under this Indenture, they may,
but need not, be consolidated and form one instrument.

     Section 1.04. Acts of Holders; Record Dates.

     (a) Any request, demand, authorization, direction, notice, consent, waiver or other action
provided or permitted by this Indenture to be given, made or taken by Holders may be embodied in
and evidenced by one or more instruments of substantially similar tenor signed by such Holders in
person or by an agent duly appointed in writing; and, except as herein otherwise expressly
provided, such action shall become effective when such instrument or instruments are delivered to
the Trustee and, where it is hereby expressly required, to the Company. The Trustee shall promptly
deliver to the Company copies of all such instruments or instruments and records delivered to the
Trustee. Such instrument or instruments (and the action embodied therein and evidenced thereby)
are herein sometimes referred to as the “Act” of the Holders signing such instrument or
instruments. Proof of execution of any such instrument or of a writing appointing any such agent
shall be sufficient for any purpose of this Indenture and (subject to Section 6.01)
conclusive in favor of the Trustee and the Company, if made in the manner provided in this Section.

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

     (c) The Company may, in the circumstances permitted by the Trust Indenture Act, fix any day as
the record date (which need not comply with Section 316(c) of the Trust Indenture Act) for the
purpose of determining the Holders entitled to give or take any request, demand, authorization,
direction, notice, consent, waiver or other action, or to vote on any action, authorized or
permitted to be given or taken by Holders. If not set by the Company prior to the first
solicitation of a Holder made by any Person in respect of any such action, or, in the case of any
such vote, prior to such vote, the record date for any such action or vote shall be the 30th day
(or, if later, the date of the most recent list of Holders required to be provided pursuant to
Section 7.01) prior to such first solicitation or vote, as the case may be. With regard to
any record date, only the Holders on such date (or their duly designated proxies) shall be entitled
to give or take, or vote on, the relevant action or to revoke the giving or taking, or voting on,
any such action previously given or taken, whether or not such Persons continue to be Holders after
such record date.

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

     (e) Any request, demand, authorization, direction, notice, consent, waiver or other Act of the
Holder of any Security shall bind every future Holder of the same Security and the

16

 

Holder of every Security issued upon the registration of transfer thereof or in exchange
therefor or in lieu thereof in respect of anything done, omitted or suffered to be done by the
Trustee or the Company in reliance thereon, whether or not notation of such action is made upon
such Security.

     Section 1.05. Notices, Etc., to Trustee and Company.

     Any request, demand, authorization, direction, notice, consent, waiver or Act of Holders or
other document provided or permitted by this Indenture to be made upon, given or furnished to, or
filed with,

     (1) the Trustee by any Holder or by the Company shall be sufficient for every purpose
hereunder if made, given, furnished or filed in writing (or by facsimile transmission to (212)
815-5704 (or such other facsimile number specified by the Trustee), provided that oral confirmation
of receipt shall have been received) to or with the Trustee at its Corporate Trust Office, or such
other means reasonably acceptable to the Trustee, or

     (2) the Company by the Trustee or by any Holder shall be sufficient for every purpose
hereunder (unless otherwise herein expressly provided) if in writing and mailed, first-class
postage prepaid, to the Company addressed to it at the address of its principal office specified in
the first paragraph of this Indenture or at any other address previously furnished in writing to
the Trustee by the Company, Attention: Chief Financial Officer, with a copy to the Secretary or
such other means reasonably acceptable to the Company.

     Section 1.06. Notice to Holders; Waiver.

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

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

17

 

     Section 1.07. Conflict With Trust Indenture Act.

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

     Section 1.08. Effect of Headings and Table of Contents.

assigns and all agreements of the Trustee in this Indenture shall bind its successors and assigns,
whether so expressed or not.

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

     Section 1.11. Benefits of Indenture.

     Nothing in this Indenture or in the Securities, express or implied, shall give to any Person,

benefit or any legal or equitable right, remedy or claim under this Indenture.

     Section 1.12. Governing Law.

INTERNAL LAWS OF THE STATE OF NEW YORK, EXCEPT TO THE EXTENT THE LAWS OF THE STATE OF NEW YORK

     Section 1.13. Legal Holidays.

     In any case where any Interest Payment Date, Redemption Date, Fundamental Change Repurchase
Date, Optional Put Repurchase Date, Stated Maturity, or the last date on which a Holder has the
right to convert his Securities, shall not be a Business Day, then (notwithstanding any other
provision of this Indenture or of the Securities) payment of Interest or principal or conversion of
the Securities need not be made on such date, but may be made on the next succeeding Business Day
with the same force and effect as if made on the Interest Payment Date, Redemption Date,
Fundamental Change Repurchase Date, Optional Put Repurchase Date, the

18

 

Stated Maturity, or on such last day for conversion, provided that no Interest shall accrue
for the period from and after such Interest Payment Date, Redemption Date, Fundamental Change
Repurchase Date, Optional Put Repurchase Date or Stated Maturity, as the case may be.

     Section 1.14. Indenture and Securities Solely Corporate Obligations.

     None of the Company’s or its Subsidiaries’ past, present or future directors, officers,
employees, incorporators or stockholders, as such, shall have any liability for any of the
Company’s obligations under this Indenture or the Securities or for any claim based on, or in
respect or by reason of, such obligations or their creation. By accepting a Security, each Holder
waives and releases all such liability. The waiver and release are part of the consideration for
the issuance of the Securities.

     Section 1.15. Indenture May Be Executed in Counterparts.

     This Indenture may be executed in any number of counterparts, each of which shall be an
original, but such counterparts shall together constitute one and the same instrument.

     The Bank of New York Trust Company, National Association, the Trustee named herein, hereby
accepts the trusts in this Indenture declared and provided, upon the terms and conditions set forth

performance of its obligations hereunder arising out of or caused by, directly or indirectly,
forces beyond its control, including strikes, work stoppages, accidents, acts of war or terrorism,
civil or military disturbances, nuclear or natural catastrophes or acts of God, and interruptions,
loss or malfunctions of utilities, communications or computer (software and hardware) services; it
being understood that the Trustee shall use reasonable efforts which are consistent with accepted
practices in the banking industry to resume performance as soon as practicable under the
circumstances.

     EACH PARTY HERETO HEREBY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT

[IF THIS NOTE IS A GLOBAL SECURITY, THEN INSERT —(which
principal amount may from time to time be increased or decreased to such other principal amounts by
adjustments made on the records of the Security Registrar hereinafter referred to in accordance
with the Indenture)] on June 1, 2038 (the “Maturity Date”), and to pay interest thereon, from June
3, 2008, or from the most recent Interest Payment Date (as defined below) to which interest has
been paid or duly provided for, semi-annually in arrears on June 1 and December 1 in each year
(each, an “Interest Payment Date”), commencing on December 1, 2008, at a rate of 3.375% per annum.
The Securities will cease to bear interest (except Contingent Interest and Additional Interest, as
applicable) on June 1, 2013, and instead from such date the principal amount of the Securities will
accrete at a rate that provides Holders with an aggregate annual yield to maturity of 3.375% per
year (computed on a semi-annual bond-equivalent basis), with the Accreted Principal Amount
compounding semi-annually. Beginning with the six-month interest period commencing on June 1,
2013, the Company will

21

 

pay Contingent Interest in accordance with the Indenture during any six-month interest period
to the Holders if the Trading Price of the Securities for each of the five Trading Days ending on,
and including, the second Trading Day immediately preceding the first day of such six-month
interest period equals or exceeds 120% of the Accreted Principal Amount of the Securities. The
Indenture also provides for the one-time payment of Additional Interest upon the occurrence of
certain events. The interest so payable, and punctually paid or duly provided for, on any Interest
Payment Date will, as provided in the Indenture, be paid to the Person in whose name this Security
(or one or more Predecessor Securities) is registered at 5:00 p.m., New York City time, on the
Regular Record Date for such interest, which shall be the May 15 or November 15 (whether or not a
Business Day), as the case may be, next preceding such Interest Payment Date. Any such interest
not so punctually paid or duly provided for will forthwith cease to be payable to the Holder on
such Regular Record Date and may either be paid to the Person in whose name this Security (or one
or more Predecessor Securities) is registered at 5:00 p.m., New York City time, on a Special Record
Date for the payment of such Defaulted Interest to be fixed by the Trustee, notice whereof shall be
given to Holders of Securities not less than 10 days prior to such Special Record Date, or be paid
at any time in any other lawful manner not inconsistent with the requirements of any securities
exchange on which the Securities may be listed, and upon such notice as may be required by such
exchange, all as more fully provided in the Indenture. Payments of principal shall be made upon
the surrender of this Security by the Holder thereof at the Corporate Trust Office of the Trustee,
or at such other office or agency of the Company as may be designated by it for such purpose, in
such lawful monies of the United States of America as at the time of payment shall be legal tender
for the payment of public and private debts. All amounts due in cash with respect to the
Securities shall be paid (A) in the case this Security is in global form, by wire transfer of
immediately available funds to the account designated by the Depositary or its nominee; (B) in the

Principal Amount of $5.0 million or less, by check mailed to such Holder; and (C) in the case this
Security is held, other than in global form, by a Holder in an aggregate Original Principal Amount
of more than $5.0 million, either by check mailed to such Holder or, upon application by such
Holder to the Security Registrar not later than the relevant record date (in the case of an
installment of interest due on an Interest Payment Date) or 15 calendar days prior to such other
date on which such amounts are due, by wire transfer in immediately available funds to such
Holder’s account within the United States, which application shall remain in effect until the
Holder notifies, in writing, the Security Registrar to the contrary.

OWNER’S SECURITIES AND IN DETERMINING ADJUSTMENTS THERETO. A HOLDER MAY OBTAIN THE ISSUE PRICE, THE

     Section 2.03. Form of Reverse of Security.

     This Security is one of a duly authorized issue of Securities of the Company designated as its
3.375% Convertible Senior Notes due 2038 (herein called the “Initial Securities”) issued and to be
issued under an Indenture, dated as of June 3, 2008 (herein called the “Indenture”), between the
Company and The Bank of New York Trust Company National Association, as Trustee (herein called the
“Trustee”, which term includes any successor trustee under the Indenture), to which Indenture and
all indentures supplemental thereto reference is hereby made for a statement of the respective
rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the
Holders of the Securities and of the terms upon which the Securities are, and are to be,
authenticated and delivered. The Company may from time to time, without notice to or the consent
of the Holders of the Securities, create and issue further Securities (the “Additional Securities”
and, together with the Initial Securities, the “Securities”) having the same terms and ranking
equally and ratably with the Initial Securities, as part of one series, in all respects, or in all
respects except for payment of interest accruing prior to the Issue Date of such Initial
Securities. Any Additional Securities shall be consolidated and form a single series with the
Initial Securities and shall have the same terms as to status, redemption, and otherwise as the
Initial Securities. Any Additional Securities may be issued pursuant to authorization provided by
a resolution of the Board of Directors of the Company, a supplement to the Indenture, or under an
Officer’s Certificate pursuant to the Indenture. No Additional Securities may be issued if an
Event of Default has occurred and is continuing with respect to the Initial Securities, and no
Additional Securities may be issued unless and until such Additional Securities are fungible with
the Initial Securities for United States federal income tax purposes.

     No sinking fund is provided for the Securities.

     In any case where any Interest Payment Date, Redemption Date, Optional Put Repurchase Date,
Fundamental Change Repurchase Date or the Maturity Date of any Security or

24

 

the last date on which a Holder has the right to convert his Securities shall not be a
Business Day, then (notwithstanding any other provision of the Indenture or of the Securities)
payment of Interest or Accreted Principal Amount or conversion of the Securities need not be made
on such date, but may be made on the next succeeding Business Day with the same force and effect as
if made on the Interest Payment Date, Redemption Date, Optional Put Repurchase Date or Fundamental
Change Repurchase Date, or at the Maturity Date, or on such last day for conversion, provided that
no Interest shall accrue for the period from and after such Interest Payment Date, Redemption Date,
Optional Put Repurchase Date, Fundamental Change Repurchase Date or the Maturity Date, as the case
may be.

     The Indenture contains provisions permitting the Company and the Trustee in certain
circumstances, without the consent of the Holders of the Securities, and in other circumstances,
with the consent of the Holders of not less than a majority in aggregate Accreted Principal Amount
of the Securities at the time outstanding, evidenced as in the Indenture provided, to execute
supplemental indentures adding any provisions to or changing in any manner or eliminating any of
the provisions of the Indenture or of any supplemental indenture or modifying in any manner the
rights of the Holders of the Securities; provided, however, that no such supplemental indenture
shall make any of the changes set forth in Section 9.02 of the Indenture that requires the consent
of each Holder of an outstanding Security affected thereby without the obtaining of such consent.
It is also provided in the Indenture that, prior to any declaration accelerating the maturity of
the Securities, the Holders of a majority in Accreted Principal Amount of the Securities at the
time outstanding may on behalf of the Holders of all of the Securities waive any past default or
Event of Default under the Indenture and its consequences except as provided in the Indenture. Any
such consent or waiver by the Holder of this Security (unless revoked as provided in the Indenture)
shall be conclusive and binding upon such Holder and upon all future holders and owners of this
Security and any Securities which may be issued in exchange or substitution hereof, irrespective of
whether or not any notation thereof is made upon this Security or such other Securities.

     No reference herein to the Indenture and no provision of this Security or of the Indenture
shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay
the Accreted Principal Amount of, and accrued and unpaid Interest on, this Security, at the place,
at the respective times, at the rate and in the lawful money herein prescribed.

     Subject to the provisions of the Indenture, upon the occurrence of a Fundamental Change or on
an Optional Put Repurchase Date, the Holder has the right, at such Holder’s option, to require the
Company to repurchase all of such Holder’s Securities or any portion thereof (in Original Principal
Amounts of $1,000 or integral multiples thereof) on the Fundamental Change Repurchase Date or
Optional Put Repurchase Date, as applicable, at a price equal to 100% of the Accreted Principal
Amount of the Securities such Holder elects to require the Company to repurchase, together with
accrued and unpaid Interest to, but excluding the Fundamental Change Repurchase Date or Optional
Put Repurchase Date, as applicable, unless such Fundamental Change Repurchase Date or Optional Put
Repurchase Date, as applicable, falls after a Regular Record Date and on or prior to the
corresponding Interest Payment Date, in which case the Company shall pay the full amount of accrued
and unpaid Interest payable on such Interest Payment Date to the Holder of record at 5:00 p.m., New
York City time, on the corresponding Regular Record Date. No later than 20 Business Days prior to
each Optional Put Repurchase

25

 

Date, the Company shall give notice to each Holder (and to beneficial owners as required by
applicable law) of their related repurchase right. The Company or, at the written request of the
Company, the Trustee shall mail to all Holders of record of the Securities a notice of the
occurrence of a Fundamental Change and of the repurchase right arising as a result thereof after
the occurrence of any Fundamental Change, but on or before the 10th calendar day following such
occurrence.

     The Holder hereof has the right, at its option, (i) upon the occurrence of certain conditions
specified in the Indenture, at any time prior to the close of business on the Scheduled Trading Day
immediately preceding March 1, 2013, or (ii) on or after March 1, 2013, at any time prior to the
close of business on the Scheduled Trading Day immediately preceding the Maturity Date, to convert
any Securities or portion thereof which is $1,000 in Original Principal Amount or an integral
multiple thereof, into shares of Common Stock (or cash or combination of cash and shares of Common
Stock, at the election of the Company, as set forth in Section 12.02 of the Indenture) or Reference
Property, in each case at the Conversion Rate specified in the Indenture, as adjusted from time to
time as provided in the Indenture, upon satisfaction of certain requirements set forth in the
Indenture, including, if applicable, the surrender of this Security, together with a Notice of
Conversion, a form of which is contained under Section 2.05 of the Indenture, as provided in the
Indenture and this Security, to the Company at the office or agency of the Company maintained for
that purpose, or at the option of such Holder, the Corporate Trust Office of the Trustee, and,
unless the shares of Common Stock or Reference Property, as the case may be, issuable on conversion
are to be issued in the same name as this Security, duly endorsed by, or accompanied by instruments
of transfer in form satisfactory to the Company duly executed by, the Holder or by his duly
authorized attorney. The initial Conversion Rate shall be 19.9695 shares of Common Stock for each
$1,000 in Original Principal Amount of Securities. No fractional shares of Common Stock or
Reference Property, as the case may be, shall be issued upon any conversion, but an adjustment in
cash shall be paid to the Holder, as provided in the Indenture, in respect of any fraction of such
share which would otherwise be issuable upon the surrender of any Security or Securities for
conversion. No adjustment shall be made for dividends or any such shares issued upon conversion of
such Securities except as provided in the Indenture.

     Upon due presentment for registration of transfer of this Security at the office or agency of
the Company, a new Security or Securities of authorized denominations for an equal aggregate
Accreted Principal Amount shall be issued to the transferee in exchange thereof, subject to the
limitations provided in the Indenture, without charge except for any tax, assessments or other
governmental charge imposed in connection therewith.

     The Company, the Trustee, any Authenticating Agent, any Paying Agent, any Conversion Agent and
any Security Registrar may deem and treat the registered Holder hereof as the absolute owner of
this Security (whether or not this Security shall be overdue and notwithstanding any notation of
ownership or other writing hereon), for the purpose of receiving payment hereof, or on account
hereof, for the conversion hereof and for all other purposes, and neither the Company nor the
Trustee nor any Authenticating Agent nor any Paying Agent nor any other Conversion Agent nor any
Security Registrar shall be affected by any notice to the contrary. All payments made to or upon
the order of such registered Holder shall, to the extent of the sum or sums paid, satisfy and
discharge liability for monies payable on this Security.

26

 

     No recourse for the payment of the Accreted Principal Amount of, or accrued and unpaid
Interest on, this Security, or for any claim based hereon or otherwise in respect hereof, and no
recourse under or upon any obligation, covenant or agreement of the Company in the Indenture or any
indenture supplemental thereto or in any Security, or because of the creation of any indebtedness
represented thereby, shall be had against any incorporator, stockholder, employee, agent, officer,
director or subsidiary, as such, past, present or future, of the Company or of any successor
corporation, either directly or through 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, all such liability being, by the acceptance hereof and as part of the consideration for
the issue hereof, expressly waived and released.

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

     In the case of any conflict between the provisions of this Security and the Indenture, the
provisions of the Indenture shall control.

     The Indenture and this Security shall be governed by and construed in accordance with the
internal laws of the State of New York, except to the extent the laws of the State of New York
require the application of the laws of another jurisdiction.

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

Interest will be payable semi-annually in arrears on each Interest Payment Date (subject to
Section 1.13) to the Holder of record at 5:00 p.m., New York City time, on the Regular
Record Date preceding such Interest Payment Date; provided that the Securities will cease to accrue
Regular Interest as of June 1, 2013.

     Section 3.03. Contingent Interest.

     (a) The Company will pay Contingent Interest in cash to Holders during any Interest Period
beginning with the six-month Interest Period commencing June 1, 2013, if the Trading Price of the
Securities for each of the five Trading Days ending on and including the second Trading Day
immediately preceding the first day of the applicable Interest Period (as used in this Section
3.03, the “Measurement Period”) equals or exceeds 120% of the Accreted Principal Amount of the
Securities.

34

 

     (b) For any Interest Period when Contingent Interest shall be payable with respect to the
Securities, the Contingent Interest payable per $1,000 in Original Principal Amount of Securities
will equal 0.40% of the average Trading Price of $1,000 in Original Principal Amount of the
Securities for the applicable Measurement Period.

     (c) The Company will promptly (and in any event prior to the applicable Interest Payment Date)
notify Holders upon determination that they will be entitled to receive Contingent Interest for an
Interest Period.

     (d) The Company shall pay Contingent Interest owed pursuant to this Section 3.03 for
any Interest Period on the Interest Payment Date immediately succeeding the applicable Interest
Period, to Holders of record at 5:00 p.m., New York City time, on the Regular Record Date related
to such Interest Payment Date.

     Section 3.04. Accretion.

     Commencing on June 1, 2013, the Original Principal Amount shall accrete at a rate that
provides Holders with an aggregate annual yield to Maturity of 3.375% per annum (computed on a
semi-annual bond-equivalent yield basis), with the Accreted Principal Amount compounding
semi-annually. Schedule B hereto sets forth the Accreted Principal Amounts as of specified
dates during the period from June 1, 2013 through the Maturity Date.

     Section 3.05. Denominations.

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

     Section 3.06. Global Securities; Non-global Securities; Book-entry Provisions.

     The Securities may be issued as Global Securities or in non-global (definitive) form as
provided in this Indenture.

     (a) Global Securities

          (i) Each Global Security authenticated under this Indenture shall be registered in the name of
Cede & Co., as nominee of DTC (the “Depositary”), and shall be delivered to the Trustee, as
custodian for the Depositary. Each such Global Security shall constitute a single Security for all
purposes of this Indenture.

          (ii) Except for exchanges of Global Securities for definitive, non-Global Securities at the
sole discretion of the Company, no Global Securities may be exchanged in whole or in part for
Securities registered, and no transfer of a Securities in whole or in part may be registered, in
the name of any Person other than the Depositary for such Global Security or a nominee thereof
unless (A) the Depositary notifies the Company that it is unwilling or unable to continue as
Depositary for the Global Security and a successor Depositary is not appointed by the Company
within 90 days of such notice, or (B) an Event of Default has occurred with respect to the
Securities and is continuing and the Security Registrar has received a request from the Depositary
to issue Securities in lieu of all or a portion of the Global Security. In the case of an

35

 

event described in clause (A), the Company shall execute, and the Trustee, upon
receipt of a Company Order directing the authentication and delivery of non-Global Securities,
shall authenticate and deliver, non-Global Securities, in any authorized denominations in an
aggregate principal amount equal to the Accreted Principal Amount of such Global Security in
exchange for such Global Security. In the case of an event described in clause (B), the
Company shall promptly upon the request of the Depositary execute, and the Trustee, upon receipt of
a Company Order directing the authentication and delivery of non-Global Securities, shall
authenticate and deliver, non-Global Securities, in any authorized denominations in an aggregate
principal amount equal to the principal amount of such Global Security that the Depositary requests
be exchanged for such interests in such Global Security.

          (iii) If any Global Security is to be exchanged for other Securities or cancelled in whole, it
shall be surrendered by or on behalf of the Depositary or its nominee to the Trustee, as Security
Registrar, for exchange or cancellation, as provided in this Article. If any Global Security is to
be exchanged for other Securities or cancelled in part, or if another Security is to be exchanged
in whole or in part for a beneficial interest in any Global Security, in each case, as provided in
Article 2 of this Indenture, then either (A) such Global Security shall be so surrendered
for exchange or cancellation, as provided in this Article, or (B) the Accreted Principal Amount
thereof shall be reduced or increased by an amount equal to the portion thereof to be so exchanged
or cancelled, or equal to the principal amount of such other Security to be so exchanged for a
beneficial interest therein, as the case may be, by means of an appropriate adjustment made on the
records of the Trustee, as Security Registrar, whereupon the Trustee, in accordance with the
Applicable Procedures, shall instruct the Depositary or its authorized representative to make a
corresponding adjustment to its records. Upon any such surrender or adjustment of a Global
Security, the Trustee shall, subject to this Article, authenticate and deliver any Securities
issuable in exchange for such Global Security (or any portion thereof) to or upon the order of, and
registered in such names as may be directed by, the Depositary or its authorized representative.
The Trustee shall be entitled to receive from the Depositary the names, addresses and tax
identification numbers of the Persons in whose name the Securities are to be registered prior to
such authentication and delivery. Upon the request of the Trustee in connection with the
occurrence of any of the events specified in the preceding paragraph, the Company shall promptly
make available to the Trustee a reasonable supply of Securities that are not in the form of Global
Securities. The Trustee shall be entitled to rely upon any order, direction or request of the
Depositary or its authorized representative which is given or made pursuant to this Article if such
order, direction or request is given or made in accordance with the Applicable Procedures (to the
extent such procedures are applicable to such direction or request).

          (iv) Every Security authenticated and delivered upon registration of transfer of, or in
exchange for or in lieu of, a Global Security or any portion thereof, whether pursuant to this
Article or otherwise, shall be authenticated and delivered in the form of, and shall be, a
registered Global Security, unless such Security is registered in the name of a Person other than
the Depositary for such Global Security or a nominee thereof, in which case such Security shall be
authenticated and delivered in accordance with clause (b) of this Section
3.06(a)(ii).

          (v) The Depositary or its nominee, as registered owner of a Global Security, shall be the
Holder of such Global Security for all purposes under this Indenture and the Securities, and owners
of beneficial interests in a Global Security shall hold such interests

36

 

pursuant to the Applicable Procedures. Accordingly, any such owner’s beneficial interest in a
Global Security shall be shown only on, and the transfer of such interest shall be effected only
through, records maintained by the Depositary or its nominee or its Agent Members and such owners
of beneficial interests in a Global Security shall not be considered the owners or holders thereof.

     (b) Non-Global Securities. Securities issued upon the events described in Section
3.06(a)(ii) shall be in definitive, fully registered form, without interest coupons.

     Section 3.07. Execution, Authentication, Delivery and Dating.

     The Securities shall be executed on behalf of the Company by its Chairman of the Board, Vice
Chairman of the Board, Chief Executive Officer, Chief Financial Officer, President or one of its
Vice Presidents, Treasurer or Assistant Treasurer and attested to by the Secretary or Assistant
Secretary of the Company. The signature of any of these officers on the Securities may be manual
or facsimile.

     Securities bearing the manual or facsimile signatures of individuals who were at any time the
proper officers of the Company shall bind the Company, notwithstanding that such individuals or any
of them have ceased to hold such offices prior to the authentication and delivery of such
Securities or did not hold such offices at the date of such Securities.

     At any time and from time to time after the execution and delivery of this Indenture, the
Company may deliver Securities executed by the Company to the Trustee for authentication, together
with a Company Order for the authentication and delivery of such Securities; and the Trustee in
accordance with such Company Order shall authenticate and deliver such Securities as in this
Indenture provided and not otherwise.

     Each Security shall be dated the date of its authentication.

     No Security shall be entitled to any benefit under this Indenture or be valid or obligatory
for any purpose unless there appears on such Security a certificate of authentication substantially
in the form provided for herein executed by the Trustee by manual signature, and such certificate
upon any Security shall be conclusive evidence, and the only evidence, that such Security has been
duly authenticated and delivered hereunder and entitled to the benefits hereof. Notwithstanding
the foregoing, if any Security shall have been authenticated and delivered hereunder but never
issued and sold by the Company, and the Company shall deliver such Security to the Trustee for
cancellation as provided in Section 3.13, for all purposes of this Indenture such Security
shall be deemed never to have been authenticated and delivered hereunder and shall never be
entitled to the benefits of this Indenture.

     The Company may, subject to Article 10 of this Indenture and applicable law, issue
Additional Securities under this Indenture; provided, however, that the Company may not issue
Additional Securities if an Event of Default with respect to any Outstanding Securities shall have
occurred and be continuing at the time of such issuance and provided, further, that no Additional
Securities shall be issued unless and until such Additional Securities are fungible with the
Initial Securities for U.S. federal income tax purposes. All Securities issued under this
Indenture shall be treated as a single class for all purposes under this Indenture.

37

 

     Section 3.08. Temporary Securities.

     Pending the preparation of definitive Securities, the Company may execute, and upon Company
Order the Trustee shall authenticate and deliver, temporary Securities which are printed,
lithographed, typewritten, mimeographed or otherwise produced, in any authorized denomination,
substantially of the tenor of the definitive Securities in lieu of which they are issued and with
such appropriate insertions, omissions, substitutions and other variations as the officers
executing such Securities may determine, as evidenced by their execution of such Securities.

     If temporary Securities are issued, the Company will cause definitive Securities to be
prepared without unreasonable delay. After the preparation of definitive Securities, the temporary
Securities shall be exchangeable for definitive Securities upon surrender of the temporary
Securities at any office or agency of the Company designated pursuant to Section 10.02,
without charge to the Holder. Upon surrender for cancellation of any one or more temporary
Securities the Company shall execute and the Trustee shall authenticate and deliver in exchange
therefor a like principal amount of definitive Securities of authorized denominations. Until so
exchanged the temporary Securities shall in all respects be entitled to the same benefits under
this Indenture as definitive Securities.

     Section 3.09. Security Registrar, Registration of Transfer and Exchange; Paying Agent.

     (a) Security Registrar. The Company shall cause to be kept at the Corporate Trust Office of
the Trustee a register (the register maintained in such office and in any other office or agency
designated pursuant to Section 10.02 being herein sometimes collectively referred to as the
“Security Register”) in which, subject to such reasonable regulations as it may prescribe, the
Company shall provide for the registration of Securities and for the transfers or exchange of
Securities. Such Security Register shall distinguish between Initial Securities and Additional
Securities to the extent that such Securities are not fungible in all respects. The Trustee is
hereby appointed “Security Registrar” for the purpose of registering Securities and transfers and
exchanges of Securities as herein provided. The Company may change the Security Registrar without
notice to any Holder. The Company or any of its Subsidiaries may act as Security Registrar.

     Upon surrender for registration of transfer of any Security at an office or agency of the
Company designated pursuant to Section 10.02 for such purpose, the Company shall execute,
and the Trustee shall authenticate and deliver, in the name of the designated transferee or
transferees, one or more new Securities of any authorized denomination, provided that such
denomination is a minimum of $1,000 in Original Principal Amount or an integral multiple thereof,
and of a like aggregate Accreted Principal Amount, each such Security bearing such restrictive
legends as may be required by this Indenture.

     At the option of the Holder and subject to the other provisions of this Section 3.09
and to Section 3.13, Securities may be exchanged for other Securities of any authorized
denominations and of a like tenor and aggregate Accreted Principal Amount, upon surrender of the
Securities to be exchanged at such office or agency. Whenever any Securities are so surrendered
for

38

 

exchange, the Company shall execute, and the Trustee shall authenticate and deliver, the
Securities which the Holder making the exchange is entitled to receive.

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

     Every Security presented or surrendered for registration of transfer or for exchange shall (if
so required by the Company or the Trustee) be duly endorsed, or be accompanied by a written
instrument of transfer in form satisfactory to the Company and the Security Registrar duly
executed, by the Holder thereof or his attorney duly authorized in writing. As a condition to the
registration of transfer of any Restricted Securities, the Company or the Trustee may require
evidence satisfactory to them as to the compliance with the restrictions set forth in the legend of
such Securities.

     Except as provided in the following sentence and in Section 3.13, all Securities
originally issued hereunder and all Securities issued upon registration of transfer or exchange or
replacement thereof shall be Restricted Securities and shall bear the legend required by
Section 2.02, unless the Company shall have delivered to the Trustee (and the Security
Registrar, if other than the Trustee) a Company Order stating that the Security is not a Restricted
Security and may be issued without such legend thereon. The Company agrees for the benefit of the
Holders that upon any request in writing as promptly as practicable but in any event within three
Business Days of receipt of such written request and, in any event, promptly following the day that
is one year following the last date of original issuance of the Securities (including through the
exercise of the Initial Purchasers’ option to purchase additional Securities), to deliver a Company
Order stating that the Security is not a Restricted Security and may be issued without the related
legend thereon and thereafter cause the Securities to be represented by a certificate bearing a
CUSIP number that represents that a person who is not an affiliate of the Company pursuant to Rule
144 (or any successor provision thereto) can resell such Securities without any volume or manner of
sale restrictions thereunder. Securities that are issued upon registration of transfer of, or in
exchange for, Securities that are not Restricted Securities shall not be Restricted Securities and
shall not bear such legend.

     No service charge shall be made for any registration of transfer or exchange of Securities,
but the Company, the Trustee or the Security Registrar may require payment of a sum sufficient to
cover any transfer tax or other similar governmental charge required by law payable in connection
therewith, other than exchanges pursuant to Section 3.07, Section 9.06 or
Section 12.02 not involving any transfer.

     Notwithstanding any other provisions of this Indenture to the contrary, except as set forth in
Section 3.06, the Company shall not be required to register the transfer or exchange of (a)
any Security surrendered for conversion in accordance with Article 12, (b) any Security
selected for redemption in whole or in part pursuant to Article 11, except the unredeemed
portion of any Security being redeemed in part, or (c) any Security during the period beginning 15
Business Days prior to the mailing of an Optional Put Repurchase Offer or Fundamental Change
Repurchase Right Notice required pursuant to Section 11.08 or Section 11.09, as
applicable, or a

39

 

notice of redemption of Securities to be redeemed and ending at the close of business on the
day of mailing.

     (b) Restrictions on Transfer. Beneficial ownership of every Restricted Security shall be
subject to the restrictions on transfer provided in the legend required to be set forth on the face
of each Restricted Security pursuant to Section 2.02, unless such restrictions on transfer
shall be terminated in accordance with this Section 3.09(b) or Section 3.13. The
Holder of each Restricted Security, by such Holder’s acceptance thereof, agrees to be bound by such
restrictions on transfer.

     The restrictions imposed by this Section 3.09 and by Section 2.02 and
Section 3.13 upon the transferability of any particular Restricted Security shall cease and
terminate upon such Restricted Security having been transferred in compliance with Rule 144 under
the Securities Act (or any successor provision thereto). Any Restricted Security as to which the
restrictions on transfer shall have expired in accordance with their terms or shall have terminated
may, upon surrender of such Restricted Security for exchange to the Security Registrar in
accordance with the provisions of this Section 3.09, be exchanged for a new Security, of
like tenor and aggregate Accreted Principal Amount, which shall not bear the restrictive legend
required by Section 2.02.

     Prior to the first anniversary of the last date of original issuance of the Securities
(including through the exercise of the Initial Purchasers’ option to purchase additional
Securities), the Securities may not be sold by any affiliate (within the meaning of Rule 144 under
the Securities Act) of the Company, except pursuant to an effective registration statement or in
compliance with Rule 144.

     As used in the preceding three paragraphs of this Section 3.09, the term “transfer”
encompasses any sale, pledge, transfer or other disposition of any Restricted Security.

     (c) Paying Agent. The Company shall maintain an office or agency in New York, New York where
Securities may be presented for payment (the “Paying Agent”). The Company initially appoints the
Trustee as Paying Agent for the Securities. The Company may have one or more additional paying
agents and the term “Paying Agent” shall include any such additional paying agent.

     The Company shall enter into an appropriate agency agreement with any Paying Agent not a party
to this Indenture, which shall incorporate the terms of the Trust Indenture Act, except in the case
of a Paying Agent that acts as Paying Agent solely in connection with an offer to purchase the
Securities pursuant to Article 10 of this Indenture. The agreement shall implement the
provisions of this Indenture that relate to such agent. The Company shall notify the Trustee of
the name and address of each such agent. If the Company fails to maintain a Paying Agent, the
Trustee shall act as such and shall be entitled to compensation therefor pursuant to Section
6.07. The Company or any of its Subsidiaries may act as Paying Agent.

     The Company may remove any Paying Agent upon written notice to such Paying Agent and to the
Trustee; provided, however, that no such removal shall become effective until (i) acceptance of any
appointment by a successor as evidenced by an appropriate agreement entered into by the Company and
such successor Paying Agent, as the case may be, and delivered to the

40

 

Trustee or (ii) notification to the Trustee that the Trustee or the Company shall serve as
Paying Agent until the appointment of a successor in accordance with clause (i) above. The
Paying Agent may resign at any time upon written notice to the Company and the Trustee.

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

     (e) Custodian. The Company hereby appoints the Trustee as custodian with respect to any
Global Securities.

     Section 3.10. Mutilated, Destroyed, Lost and Stolen Securities.

     If any mutilated Security is surrendered to the Trustee, the Company shall execute and the
Trustee shall authenticate and deliver in exchange therefor a new Security of like tenor and
Accreted Principal Amount and bearing a number not contemporaneously outstanding.

     If there shall be delivered to the Company and the Trustee (i) evidence to their satisfaction
of the destruction, loss or theft of any Security and (ii) such security or indemnity as may be
required by them to save each of them and any agent of either of them harmless, then, in the
absence of notice to the Company or the Trustee that such Security has been acquired by a bona fide
purchaser, the Company shall execute and the Trustee shall authenticate and deliver, in lieu of any
such destroyed, lost or stolen Security, a new Security of like tenor and principal amount and
bearing a number not contemporaneously outstanding.

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

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

     Every new Security issued pursuant to this Section in lieu of any destroyed, lost or stolen
Security shall constitute an original additional contractual obligation of the Company, whether or

41

 

not the destroyed, lost or stolen Security shall be at any time enforceable by anyone, and
shall be entitled to all the benefits of this Indenture equally and proportionately with any and
all other Securities duly issued hereunder.

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

     Section 3.11. Payment of Interest; Interest Rights Preserved.

     Interest on any Security which is payable, and is punctually paid or duly provided for, on any
Interest Payment Date shall be paid to the Person in whose name that Security (or one or more
Predecessor Securities) is registered at 5:00 p.m., New York City time, on the Regular Record Date
for such Interest.

     In the case of Securities represented by a Global Security registered in the name of or held
by a Depositary or its nominee, payment of principal and Interest will be made to the Depositary or
its nominee, as the case may be, as the registered owner or Holder of such Global Security. None
of the Company, the Trustee, the Paying Agent, any Authenticating Agent or the Security Registrar
for such Securities will have any responsibility or liability for any aspect of the records
relating to or payments made on account of a beneficial ownership interest in a Global Security or
maintaining, supervising or reviewing any records relating to such beneficial ownership interests.

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

     Subject to the provisions of Article 12 hereof, in the case of any Security which is
converted after 5:00 p.m., New York City time, on any Regular Record Date and on or prior to the
next succeeding Interest Payment Date, Interest whose Stated Maturity is on such Interest Payment
Date shall be payable on such Interest Payment Date notwithstanding such conversion, and such
Interest (whether or not punctually paid or duly provided for) shall be paid to the Person in whose
name that Security (or one or more Predecessor Securities) is registered at 5:00 p.m., New York
City time, on such Regular Record Date. Except as otherwise expressly provided in the immediately
preceding sentence or in Article 12 hereof, in the case of any Security (or any part
thereof) which is converted, Interest whose Stated Maturity is after the Conversion Date of such
Security (or any part thereof) shall not be payable (except with respect to that part of the
Security that is not converted).

     Section 3.12. Persons Deemed Owners.

     Prior to due presentment of a Security for registration of transfer, the Company, the Trustee
and any agent of the Company or the Trustee shall treat the Person in whose name such Security is
registered as the owner of such Security for the purpose of receiving payment of principal of and
(subject to Section 3.11) Interest on such Security and for all other purposes

42

 

whatsoever, whether or not such Security be overdue, and neither the Company, the Trustee nor
any agent of the Company or the Trustee shall be affected by notice to the contrary.

     In the case of a Global Security, so long as the Depositary for such Global Security, or its
nominee, is the registered owner of such Global Security, such Depositary or such nominee, as the
case may be, will be considered the sole owner or Holder of the Securities represented by such
Global Security for all purposes under this Indenture. Except as provided in Section 3.09,
owners of beneficial interests in a Global Security will not be entitled to have Securities that
are represented by such Global Security registered in their names, will not receive or be entitled
to receive physical delivery of such Securities in definitive form and will not be considered the
owners or Holders thereof under this Indenture.

     Notwithstanding the foregoing, with respect to any Global Security, nothing herein shall (a)
prevent the Company, the Trustee, or any agent of the Company or the Trustee, from giving effect to
any written certification, proxy or other authorization furnished by a Depositary or (b) impair, as
between a Depositary and holders of beneficial interest in any Global Security, the operation of
customary practices governing the exercise of the rights of the Depositary as Holder of such Global
Security.

     Section 3.13. Cancellation and Transfer Provisions.

     (a) All Securities surrendered for payment, repurchase, registration of transfer or exchange
or conversion shall, if surrendered to any Person other than the Trustee, be delivered to the
Trustee and shall be promptly cancelled by it. The Company may at any time deliver to the Trustee
for cancellation any Securities previously authenticated and delivered hereunder which the Company
may have acquired in any manner whatsoever, and may deliver to the Trustee (or to any other Person
for delivery to the Trustee) for cancellation any Securities previously authenticated hereunder
which the Company has not issued and sold, and all Securities so delivered shall be promptly
cancelled by the Trustee. No Securities shall be authenticated in lieu of or in exchange for any
Securities cancelled as provided in this Section, except as expressly permitted by this Indenture.
All cancelled Securities held by the Trustee shall be disposed of in accordance with its customary
procedures. Copies of all cancelled Securities shall be provided to the Company by the Trustee,
promptly following cancellation of such Securities.

     (b) Transfers to QIBs. The following provisions shall apply with respect to the registration
of any proposed transfer of a Security constituting a Restricted Security to a QIB:

          (i) the Security Registrar shall register the transfer if such transfer is being made by a
proposed transferor who has checked the box provided for on the form of Security stating, or has
otherwise advised the Company and the Security Registrar in writing, that the sale has been made in
compliance with the provisions of Rule 144A to a transferee who has signed the certification
provided for on the form of Security stating, or has otherwise advised the Company and the Security
Registrar in writing, that it is purchasing the Security for its own account or an account with
respect to which it exercises sole investment discretion and that it and any such account is a QIB
within the meaning of Rule 144A, and is aware that the sale to it is being made in reliance on Rule
144A and acknowledges that it has received such information regarding the Company as it has
requested pursuant to Rule 144A or has determined not to

43

 

request such information and that it is aware that the transferor is relying upon its
foregoing representations in order to claim the exemption from registration provided by Rule 144A;
and

          (ii) if the proposed transferee is an Agent Member, and the Securities to be transferred
consist of non-Global Securities which after transfer are to be evidenced by an interest in the
Global Security, upon receipt by the Security Registrar of instructions given in accordance with
the Depositary’s and the Security Registrar’s procedures, the Security Registrar shall reflect on
its books and records the date and an increase in the principal amount of the Global Security in an
amount equal to the principal amount of the non-Global Securities to be transferred, and the
Trustee shall cancel the non-Global Securities so transferred.

     (c) Private Placement Legend. Upon the Securities becoming, and during the period the
Securities remain, eligible for resale by non-affiliates pursuant to Rule 144, without any volume
or manner of sale restrictions, upon the registration of transfer, exchange or replacement of
Securities bearing the legend required by Section 2.02, the Security Registrar shall
deliver Securities that do not bear such legends.

     (d) General. By its acceptance of any Security bearing the legend required by Section
2.02, each Holder of such a Security acknowledges the restrictions on transfer of such Security
set forth in this Indenture and in such legends and agrees that it will transfer such Security only
as provided in this Indenture.

     The Security Registrar shall retain, in accordance with its customary procedures, copies of
all letters, notices and other written communications received pursuant to this Section
3.13. The Company shall have the right to inspect and make copies of all such letters, notices
or other written communications at any reasonable time upon the giving of reasonable written notice
to the Security Registrar.

     Section 3.14. CUSIP Numbers.

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

     Section 3.15. Computation of Interest.

     Interest on the Securities shall be computed on the basis of a 360-day year of twelve 30-day
months.

     Section 3.16. Special Record Date.

     Any Interest on any Security that is payable but not punctually paid or duly provided for on
any Interest Payment Date (“Defaulted Interest”) shall forthwith cease to be payable to the Holder
on the relevant Regular Record Date by virtue of his, her or its having been such a

44

 

Holder, and such Defaulted Interest may be paid by the Company, at its election in each case,
as provided in clause (a) or (b) below:

     (a) The Company may elect to make payment of any Defaulted Interest to Holders in whose names
the Securities are registered at 5:00 p.m., New York City time, on a special record date for the
payment of such Defaulted Interest (a “Special Record Date”), which shall be fixed in the following
manner. The Company shall notify the Trustee in writing of the Defaulted Interest proposed to be
paid on each Security and the date of the proposed payment, and at the same time the Company shall
deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in
respect of such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such
deposit prior to the date of the proposed payment, such money when deposited to be held in trust
for the benefit of the Holders entitled to such Defaulted Interest as in this clause provided.
Thereupon the Trustee shall fix a Special Record Date for the payment of such Defaulted Interest
which shall be not more than 15 calendar days and not less than 10 calendar days prior to the date
of the proposed payment and not less than 10 calendar days after the receipt by the Trustee of the
notice of the proposed payment. The Trustee shall promptly notify the Company of such Special
Record Date and, in the name and at the expense of the Company, shall cause notice of the proposed
payment of such Defaulted Interest and the Special Record Date therefor to be mailed, first-class
postage prepaid, to the Holders of the Securities at their addresses as they appear in the Security
Register, or by such other means reasonably acceptable to such Holders, not less than 10 calendar
days prior to such Special Record Date. Notice of the proposed payment of such Defaulted Interest
and the Special Record Date therefor having been mailed as aforesaid, such Defaulted Interest shall
be paid to the Persons in whose names the Securities (or their predecessor Securities) are
registered at 5:00 p.m., New York City time, on such Special Record Date and shall no longer be
payable pursuant to the following clause (b).

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

          (ii) all such Securities not theretofore delivered to the Trustee for cancellation

               (A) have become due and payable, and

               (B) the Company has deposited or caused to be deposited with the Trustee as trust funds in

under Section 6.14 and, if money or Common Stock (or Reference Property) shall have been

the principal and Interest or in settlement of the Company’s conversion obligations, as the case
may be.

ARTICLE 5

REMEDIES

     Section 5.01. Events of Default.

     Each of the following is an “Event of Default”:

     (a) default in any payment of Interest with respect to any Security when due and payable and
such default continues for a period of 30 days;

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

     (c) failure by the Company to comply with its obligations under Article 8 hereof;

     (d) failure by the Company to comply for two Business Days with its obligations under
Article 12 hereof to convert Securities into shares of Common Stock (or cash or a
combination of cash and shares of Common Stock, if the Company so elects) and, if applicable,
Reference Property, upon exercise by a Holder of its conversion right;

     (e) failure by the Company to comply for two Business Days with its obligation to deliver a
Fundamental Change Repurchase Right Notice under Article 11;

     (f) failure by the Company to comply for 90 days after written notice from the Trustee or the
Holders of at least 25% of the aggregate Original Principal Amount of the Securities then
outstanding has been received by the Company to comply with any of the Company’s other agreements
contained in the Securities or this Indenture;

     (g) default by the Company or any Subsidiary with respect to any mortgage, agreement or other
instrument under which there may be outstanding, or by which there may be secured or evidenced, any
debt for money borrowed in excess of (i) $50 million or (ii) if the Company’s primary credit
agreement contains a lower threshold dollar amount in respect of a similar default provision, such
lower amount, in each case in the aggregate of the Company and/or any of its Subsidiaries, whether
such debt now exists or is hereafter created, which default results (i) in such debt becoming or
being declared due and payable and such debt has not been discharged in full or such declaration
rescinded or annulled within 30 days or (ii) from a failure to pay the principal of any such debt
when due and payable at its stated maturity, upon required repurchase, upon declaration or
otherwise, and such defaulted payment shall not have been made, waived or extended within 30 days;

     (h) failure by the Company or any of its Subsidiaries, within 30 days, to pay, bond or
otherwise discharge any final and non-appealable judgments or orders for the payment of money the
total uninsured amount of which for the Company or any of its Subsidiaries exceeds in the aggregate
(i) $50 million or (ii) if the Company’s primary credit agreement contains a lower threshold dollar
amount in respect of a similar default provision, such lower amount, which are not stayed on
appeal;

47

 

     (i) (A) a proceeding is commenced seeking a decree or order for (i) relief in respect of the
Company or a Significant Subsidiary in an involuntary case under any applicable Bankruptcy Law,
(ii) appointment of a receiver, liquidator, assignee, custodian, trustee, examiner, administrator,
sequestration or similar official of the Company or a Significant Subsidiary or for all or
substantially all of the property and assets of the Company or a Significant Subsidiary or (iii)
the winding up or liquidation of the affairs of the Company or a Significant Subsidiary (other
than, except in the case of the Company, a solvent winding up or liquidation in connection with a
transfer of assets among the Company and its Subsidiaries) under any applicable Bankruptcy Law and,
in each case, such proceeding shall remain unstayed and in effect for a period of 60 consecutive
days; or (B) the Company or a Significant Subsidiary (i) commences a voluntary case (including
taking any action for the purpose of winding up) under any applicable Bankruptcy Law, or consents
to the entry of an order for relief in an involuntary case under any such law, (ii) consents to the
appointment of or taking possession by a receiver, liquidator, assignee, custodian, trustee,
examiner, administrator, sequestration or similar official of the Company or a Significant
Subsidiary or for all or substantially all of the property and assets of the Company or a
Significant Subsidiary or (iii) effects any general assignment for the benefit of creditors.

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

     When a default or Event of Default is cured or waived pursuant to the provisions hereof, it
ceases.

     To constitute notice under clause (f) above, the notice delivered pursuant such clause must
specify the default, demand that it be remedied and state that the notice is a “Notice of Default.”

     Section 5.02. Acceleration of Maturity; Rescission and Annulment.

     Upon obtaining knowledge of the occurrence of an Event of Default, the Company shall promptly
notify the Trustee in writing. If an Event of Default occurs and is continuing, then and in every
such case except as provided below, the Trustee or the Holders of not less than 25% in Original
Principal Amount of the Outstanding Securities may (and the Trustee at the request of such Holders
shall) declare 100% of the principal of and accrued and unpaid Interest on all the Securities to be
due and payable immediately, by a notice in writing to the Company (and to the Trustee if given by
Holders), and upon any such declaration such principal and Interest shall become immediately due
and payable. However, upon an Event of Default arising out of Section 5.01(i) with respect
to the Company, the principal of all the Securities, plus accrued and unpaid Interest to the
acceleration date, shall be due and payable immediately without notice from the Trustee or Holders.

     Notwithstanding the foregoing, at the election of the Company, the sole remedy for an Event of
Default specified in Section 5.01(f) relating to any obligations the Company may have or is
deemed to have under Section 314(a)(1) of the Trust Indenture Act relating to the

48

 

Company’s failure to file any documents or reports that the Company is required to file with
the SEC pursuant to Section 13 or 15(d) of the Exchange Act or of its covenants set forth in
Section 7.04 (any such Event of Default, a “Reporting Event of Default”), shall for the
first 120 calendar days after the occurrence of such Event of Default consist exclusively of the
right (the “Extension Right”) to receive an extension fee on the Securities in an amount equal to
0.25% of the Accreted Principal Amount of the Securities (the “Extension Fee”). On the 121st day
after such Reporting Event of Default (if such violation is not cured or waived prior to such 121st
calendar day), then the Securities will be subject to acceleration as provided in the second
sentence of the first paragraph of this Section 5.02. In the event the Company does not
elect to pay the Extension Fee upon any such Reporting Event of Default in accordance with this
Section 5.02, the Securities will be subject to acceleration as provided in the second
sentence of the first paragraph of this Section 5.02.

     In order to exercise the Extension Right and elect to pay the Extension Fee as the sole remedy
during the first 120 days after the occurrence of any Reporting Event of Default, the Company shall
(i) notify the Holders, the Paying Agent and the Trustee of such election at any time prior to the
close of business on the first Business Day following the date on which such Reporting Event of
Default occurs and (ii) pay the Extension Fee on or before the close of business on the date on
which such Reporting Event of Default occurs. Upon failure by the Company to timely give such
notice or pay the Extension Fee in accordance with the preceding sentence, the Securities will be
immediately subject to acceleration as provided in the second sentence of the first paragraph of
this Section 5.02. Unless and until a Responsible Officer of the Trustee receives at the
Corporate Trust Office such notice, the Trustee may assume without inquiry that the Extension Fee
is not payable. If the Extension Fee has been paid by the Company directly to the Persons entitled
to it, the Company shall deliver to the Trustee a certificate setting forth the particulars of such
payment.

     Notwithstanding the foregoing, (i) the election by the Company to pay an Extension Fee shall
not affect the Company’s obligation, if any, to pay Additional Interest in accordance with
Section 10.06, and (ii) if an event of default occurs under any series of the Company’s
debt securities (other than the Securities ) issued subsequent to the Issue Date of the Initial
Securities resulting from the Company’s failure to file any documents or reports that the Company
is required to file with the SEC pursuant to Section 13 or 15(d) of the Exchange Act, and such
event of default is not subject to extension on terms similar to those set forth in the foregoing
paragraphs and results in the principal amount of such debt securities becoming due and payable,
then the Extension Right shall no longer apply and the Securities shall be subject to acceleration
as provided in the second sentence of the first paragraph of this Section 5.02.

     This Section 5.02, however, is subject to the conditions that if, at any time after
the principal of and Interest on the Securities 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 Securities and the principal of any and
all Securities 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 Securities during
the period of such default), and if (a) rescission would not conflict with any

49

 

judgment or decree of a court of competent jurisdiction and (b) any and all Events of Default
under this Indenture with respect to such Securities, other than the nonpayment of principal of and
accrued and unpaid Interest on such Securities or failure to deliver amounts due upon conversion
that shall have become due solely by such acceleration, shall have been cured or waived pursuant to
Section 5.13, then and in every such case the Holders of a majority in aggregate Original
Principal Amount of the Outstanding Securities, by written notice to the Company and to the
Trustee, may waive all defaults or Events of Default with respect to the Securities (other than
with respect to the nonpayment of principal of and accrued and unpaid Interest, or failure to
deliver amounts due upon conversion, on such Securities) 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.

     Section 5.03. Collection of Indebtedness and Suits for Enforcement by Trustee.

     The Company covenants that if:

     (a) default is made in the payment of any Interest on any Security when such Interest becomes
due and payable and such default continues for a period of 30 days, or

     (b) default is made in the payment of the principal of any Security at the Maturity thereof,

the Company will, upon demand of the Trustee, pay to it, for the benefit of the Holders of such
Securities, the whole amount then due and payable on such Securities for principal and Interest,
and, to the extent that payment of such Interest shall be legally permissible, interest on any
overdue principal and on any overdue Interest, at the rate borne by the Securities, and, in
addition thereto, such further amount as shall be sufficient to cover the costs and expenses of
collection, including the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel.

     If an Event of Default occurs and is continuing, the Trustee may in its discretion proceed to
protect and enforce its rights and the rights of the Holders by such appropriate judicial
proceedings as the Trustee shall deem most effectual to protect and enforce any such rights,
whether for the specific enforcement of any covenant or agreement in this Indenture or in aid of
the exercise of any power granted herein, or to enforce any other proper remedy.

     Section 5.04. Trustee May File Proofs of Claim.

     In case of any judicial proceeding relative to the Company (or any other obligor upon the
Securities), its property or its creditors, the Trustee shall be entitled and empowered, by
intervention in such proceeding or otherwise, to take any and all actions authorized under the
Trust Indenture Act in order to have claims of the Holders and the Trustee allowed in any such
proceeding. In particular, the Trustee shall be authorized to collect and receive any moneys or
other property payable or deliverable on any such claims and to distribute the same; and any
custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any
such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee

50

 

and, in the event that the Trustee shall consent to the making of such payments directly to
the Holders, to pay to the Trustee any amount due it for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the
Trustee under Section 6.07.

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

     Section 5.05. Trustee May Enforce Claims Without Possession of Securities.

     All rights of action and claims under this Indenture or the Securities may be prosecuted and
enforced by the Trustee without the possession of any of the Securities or the production thereof
in any proceeding relating thereto, and any such 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 Securities in
respect of which such judgment has been recovered.

     Section 5.06. Application of Money Collected.

     Subject to Article 12, any money or property money collected by the Trustee pursuant
to this Article shall be applied in the following order, at the date or dates fixed by the Trustee
and, in case of the distribution of such money on account of principal or Interest, upon
presentation of the Securities and the notation thereon of the payment if only partially paid and
upon surrender thereof if fully paid:

     FIRST: To the payment of all amounts due the Trustee under Section 6.07;

     SECOND: To the payment of the amounts then due and unpaid for principal of and Interest on
the Securities in respect of which or for the benefit of which such money has been collected,
ratably, without preference or priority of any kind, according to the amounts due and payable on
such Securities for principal and Interest, respectively; and

     THIRD: The balance, if any, to the Company or an other Person or Persons entitled thereto.

     Section 5.07. Limitation on Suits.

     Subject to Section 5.08, no Holder of any Security shall have any right to institute
any proceeding, judicial or otherwise, with respect to this Indenture, or for the appointment of a
receiver or trustee, or for any other remedy hereunder, unless:

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

51

 

     (b) the Holders of not less than 25% in Original Principal Amount of the Outstanding
Securities shall have made written request to the Trustee to institute proceedings or to pursue any
other remedy in respect of such Event of Default in its own name as Trustee hereunder;

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

     (d) the Trustee has not instituted any such proceeding within 60 days of such written request
and offer of security or indemnity; and

     (e) the Holders of a majority of the aggregate Original Principal Amount of the Outstanding
Securities have not given the Trustee a direction that, in the opinion of the Trustee, is
inconsistent with such written request within such 60-day period;

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

     Section 5.08. Unconditional Right of Holders to Receive Principal and Interest and to Convert.

     Notwithstanding any other provision in this Indenture, the Holder of any Security shall have
the right, which is absolute and unconditional, to receive payment of the principal of and (subject
to Section 3.11) Interest on such Security on the respective Stated Maturities expressed in
such Security and to convert such Security in accordance with Article 12 and to institute
suit for the enforcement of any such payment and right to convert, and such rights shall not be
impaired without the consent of such Holder.

     Section 5.09. Restoration of Rights and Remedies.

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

     Section 5.10. Rights and Remedies Cumulative.

     Except as otherwise provided with respect to the replacement or payment of mutilated,
destroyed, lost or stolen Securities in the last paragraph of Section 3.10, no right or
remedy herein conferred upon or reserved to the Trustee or to the Holders is intended to be
exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted
by law, be cumulative and in addition to every other right and remedy given hereunder or now or
hereafter

52

 

existing at law or in equity or otherwise. The assertion or employment of any right or remedy
hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other
appropriate right or remedy.

     Section 5.11. Delay or Omission Not Waiver.

     No delay or omission of the Trustee or of any Holder of any Security to exercise any right or
remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a
waiver of any such Event of Default or an acquiescence therein. Every right and remedy given by
this Article or by law to the Trustee or to the Holders may be exercised from time to time, and as
often as may be deemed expedient, by the Trustee (subject to the limitations contained in this
Indenture) or by the Holders, as the case may be.

     Section 5.12. Control by Holders.

     The Holders of a majority in Original Principal Amount of the Outstanding Securities shall
have the right to direct the time, method and place of conducting any proceeding for any remedy
available to the Trustee or exercising any trust or power conferred on the Trustee, provided that

     (a) such direction shall not be in conflict with any rule of law or with this Indenture,

     (b) the Trustee may take any other action deemed proper by the Trustee which is not
inconsistent with such direction or this Indenture, and

     (c) the Trustee shall have been provided with indemnity satisfactory to it in its sole
discretion.

     Section 5.13. Waiver of Past Defaults.

     The Holders of not less than a majority in Original Principal Amount of the Outstanding
Securities may on behalf of the Holders of all the Securities (including, without limitation, in
connection with a purchase of, or tender offer or exchange offer for, the Securities) waive any
past default hereunder and its consequences, except a default:

     (a) in the payment of the principal of or Interest on any Security or in the performance of
the Company’s obligation to convert Securities and deliver cash, Common Stock and/or Reference
Property due upon conversion, in each case that remains uncured, or

     (b) in respect of a covenant or provision hereof which under Article 9 cannot be
modified or amended without the consent of the Holder of each Outstanding Security affected.

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

53

 

     Section 5.14. Undertaking for Costs.

     In any suit for the enforcement of any right or remedy under this Indenture, or in any suit
against the Trustee for any action taken, suffered or omitted by it as Trustee, a court may require
any party litigant in such suit to file an undertaking to pay the costs of such suit, and may
assess costs against any such party litigant, in the manner and to the extent provided in the Trust
Indenture Act; provided, that neither this Section nor the Trust Indenture Act shall be deemed to
authorize any court to require such an undertaking or to make such an assessment in any suit
instituted by the Company or in any suit for the enforcement of the right to convert any Security
in accordance with Article 12.

     Section 5.15. Waiver of Stay or Extension Laws.

     The Company covenants (to the extent that it may lawfully do so) that it will not at any time
insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any
usury, stay or extension law wherever enacted, now or at any time hereafter in force, which
may affect the covenants or the performance of this Indenture; and the Company (to the extent
that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law and
covenants that it will not hinder, delay or impede the execution of any power herein granted to the
Trustee, but will suffer and permit the execution of every such power as though no such law had
been enacted.

ARTICLE 6

THE TRUSTEE

     Section 6.01. Certain Duties and Responsibilities.

     The duties and responsibilities of the Trustee shall be as provided by the Trust Indenture
Act. Notwithstanding the foregoing, no provision of this Indenture shall require the Trustee to
expend or risk its own funds or otherwise incur any financial liability in the performance of any
of its duties hereunder, or in the exercise of any of its rights or powers, if it shall have
reasonable grounds for believing that repayment of such funds or adequate indemnity against such
risk or liability is not reasonably assured to it. Whether or not therein expressly so 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. No
provision of this Indenture shall be construed to relieve the Trustee from liability for its own
negligent action, its own negligent failure to act or its own willful misconduct, subject to the
succeeding paragraph and Section 6.03; provided that (a) the Trustee shall not be liable
for any error of judgment made in good faith by a Responsible Officer unless it is proved that the
Trustee was negligent in ascertaining the pertinent facts and (b) the Trustee shall not be liable
with respect to any action it takes or omits to take in good faith with a direction received by it
pursuant to Section 5.12.

     In case an Event of Default has occurred (which has not been cured or waived), the Trustee
shall exercise such of the rights and powers vested in it by this Indenture, and use the same
degree of care and skill in its exercise, as a prudent person would exercise or use under the
circumstances in the conduct of its own affairs. The Trustee, however, may refuse to follow any
direction that conflicts with law or this Indenture, that the Trustee determines is unduly

54

 

prejudicial to the rights of any other Holder or that would require it to expend its own funds or
involve the Trustee in personal liability if it shall in its sole discretion believe that repayment
of such funds or adequate indemnity against such risk is not assured to it. Prior to taking any
action under this Indenture, the Trustee will be entitled to indemnification or security
satisfactory to it in its sole discretion against all losses, liabilities and expenses caused by
taking or not taking such action.

     Section 6.02. Notice of Defaults.

     The Trustee shall give the Holders notice of any default known to the Trustee that has
occurred and is continuing hereunder within 90 days after such default has occurred. Except in the
case of an uncured default in the payment of principal of or Interest on any Security or default in
the delivery of amounts due upon conversion of Securities, the Trustee need not
deliver the notice if and so long as a committee of trust officers of the Trustee in good
faith determines that withholding the notice is in the interests of Holders. In addition, the
Trustee shall give the Holders of Securities notice of any default actually known to it as and to
the extent provided by the Trust Indenture Act.

     Section 6.03. Certain Rights of Trustee.

     Subject to the provisions of Section 6.01:

     (a) the Trustee may rely and shall be protected in acting or refraining from acting upon any
resolution, certificate, statement, instrument, opinion, report, notice, request, direction,
consent, order, bond, debenture, note, other evidence of indebtedness or other paper or document
believed by it to be genuine and to have been signed or presented by the proper party or parties;

     (b) any request or direction of the Company mentioned herein shall be sufficiently evidenced
by a Company Request or Company Order and any resolution of the Board of Directors may be
sufficiently evidenced by a Board Resolution;

     (c) whenever in the administration of this Indenture the Trustee shall deem it desirable that
a matter be proved or established prior to taking, suffering or omitting any action hereunder, the
Trustee (unless other evidence be herein specifically prescribed) may, for any action it takes or
omits to take in good faith, rely upon an Officer’s Certificate;

     (d) the Trustee may consult with counsel on any matter relating to the Indenture or the
Securities and the advice of such counsel or any Opinion of Counsel shall be full and complete
authorization and protection in respect of any action taken, suffered or omitted by it hereunder in
good faith and in reliance thereon;

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

55

 

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

     (g) the Trustee shall not be liable for any action it takes or omits to take in good faith
which it believes to be authorized or within its rights or powers;

     (h) the Trustee may execute any of the trusts or powers hereunder or perform any duties

regardless of the form of action.

     Section 6.04. Not Responsible for Recitals or Issuance of Securities.

     The recitals contained herein and in the Securities, except the Trustee’s certificates of

     Section 6.05. May Hold Securities.

     The Trustee, any Authenticating Agent, any Paying Agent, any Conversion Agent, any Security

     (a) to pay to the Trustee from time to time reasonable compensation as shall be agreed in

     (b) except as otherwise expressly provided herein, to reimburse the Trustee upon its request
for all reasonable expenses, disbursements and advances incurred or made by the Trustee (including
with respect to any other capacity in which it acts under this Indenture) and their officers,
directors and agents in accordance with any provision of this Indenture (including the reasonable

such expense, disbursement or advance as may be attributable to its negligence, bad faith or
willful misconduct; and

     (c) to indemnify the Trustee (including with respect to any other capacity in which it acts
under this Indenture) and their officers, directors and agents for, and to hold it harmless
against, any loss, liability or expense incurred without negligence or bad faith on its part,

     Section 6.08. Disqualification; Conflicting Interests.

     If the Trustee has or shall acquire a conflicting interest within the meaning of the Trust

     Section 6.09. Corporate Trustee Required; Eligibility.

     The Trustee shall at all times satisfy the requirement of Section 310(a) of the Trust
Indenture Act. 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 said supervising or examining authority, then for the purposes of
this Section, the combined

57

 

capital and surplus of such Person shall be deemed to be its combined
capital and surplus as set forth in its most recent report of condition so published. If at any
time
the Trustee shall cease to be eligible in accordance with the provisions of this Section, it
shall resign immediately in the manner and with the effect hereinafter specified in this Article.

     Section 6.10. Resignation and Removal; Appointment of Successor.

pursuant to this Article shall become effective until the acceptance of appointment by the
successor Trustee under Section 6.11.

     (b) The Trustee may resign at any time by giving written notice thereof to the Company. If an
instrument of acceptance by a successor Trustee shall not have been delivered to the Trustee within
30 days after the giving of such notice of resignation, the resigning Trustee may, at the expense
of the Company, petition any court of competent jurisdiction for the appointment of a successor
Trustee.

     (c) The Trustee may be removed at any time by Act of the Holders of a majority in Original
Principal Amount of the Outstanding Securities, delivered to the Trustee and to the Company.

     (d) If at any time:

          (i) the Trustee shall fail to comply with Section 6.08 after written request therefor
by the Company or by any Holder who has been a bona fide Holder of a Security for at least six
months, or

          (ii) the Trustee shall cease to be eligible under Section 6.09 and shall fail to
resign after written request therefor by the Company or by any such Holder, or

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

then, in any such case, (A) the Company by a Board Resolution may remove the Trustee, or (B)
subject to Section 5.14, any Holder who has been a bona fide Holder of a Security for at
least six months may, on behalf of himself and all others similarly situated, petition any court of
competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee.

     (e) If the Trustee shall resign, be removed or become incapable of acting, or if a vacancy
shall occur in the office of Trustee for any cause, the Company, by a Board Resolution, shall
promptly appoint a successor Trustee. If, within one year after such resignation, removal or
incapability, or the occurrence of such vacancy, a successor Trustee shall be appointed by Act of
the Holders of a majority in Original Principal Amount of the Outstanding Securities delivered to
the Company and the retiring Trustee, the successor Trustee so appointed shall, forthwith upon its
acceptance of such appointment, become the successor Trustee and supersede the successor Trustee
appointed by the Company. If no successor Trustee shall have been so appointed by the
Company or the Holders and accepted appointment in the manner hereinafter provided, any

58

 

Holder
who has been a bona fide Holder of a Security for at least six months may, on behalf of himself and
all others similarly situated, petition any court of competent jurisdiction for the appointment of
a successor Trustee. Notwithstanding replacement of the Trustee pursuant to this
Section 6.10, the Company’s obligations under Section 6.07 hereof shall continue
for the benefit of the retiring Trustee.

     (f) The Company shall give notice of each resignation and each removal of the Trustee and each
appointment of a successor Trustee to all Holders in the manner provided in Section 1.06.
Each notice shall include the name of the successor Trustee and the address of its Corporate Trust
Office.

     Section 6.11. Acceptance of Appointment by Successor.

     In case of the appointment hereunder of a successor Trustee, such successor Trustee shall
execute, acknowledge and deliver to the Company and to the retiring Trustee an instrument accepting
such appointment, and thereupon the resignation or removal of the retiring Trustee shall become
effective and such successor Trustee, without any further act, deed or conveyance, shall become
vested with all the rights, powers, trusts and duties of the retiring Trustee; but, on request of
the Company or the successor Trustee, such retiring Trustee shall, upon payment of its charges,
execute and deliver an instrument transferring to such successor Trustee all the rights, powers and
trusts of the retiring Trustee and shall duly assign, transfer and deliver to such successor
Trustee all property and money held by such retiring Trustee hereunder. Upon the reasonable
written request of any such successor Trustee, the Company shall execute any and all instruments
for more fully and certainly vesting in and confirming to such successor Trustee all such rights,
powers and trusts.

     No successor Trustee shall accept its appointment unless at the time of such acceptance such
successor Trustee shall be qualified and eligible under this Article.

     Section 6.12. Merger, Conversion, Consolidation or Succession to Business.

     Any corporation into which the Trustee may be merged or converted or with which it may be
consolidated, or any corporation resulting from any merger, conversion or consolidation to which
the Trustee shall be a party, or any corporation succeeding to all or substantially all the
corporate trust business of the Trustee, shall be the successor of the Trustee hereunder, provided
such corporation shall be otherwise qualified and eligible under this Article, without the
execution or filing of any paper or any further act on the part of any of the parties hereto. In
case any Securities shall have been authenticated, but not delivered, by the Trustee then in
office, any successor by merger, conversion or consolidation to such authenticating Trustee may
adopt such authentication and deliver the Securities so authenticated with the same effect as if
such successor Trustee had itself authenticated such Securities.

     Section 6.13. Preferential Collection of Claims Against Company.

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

59

 

     Section 6.14. Appointment of Authenticating Agent.

     The Trustee may appoint an Authenticating Agent or Agents, reasonably acceptable to the
Company, which shall be authorized to act on behalf of the Trustee to authenticate Securities
issued upon original issue and upon exchange, registration of transfer, partial conversion or
pursuant to Section 3.09, and Securities so authenticated shall be entitled to the benefits
of this Indenture and shall be valid and obligatory for all purposes as if authenticated by the
Trustee hereunder. Wherever reference is made in this Indenture to the authentication and delivery
of Securities by the Trustee or the Trustee’s certificate of authentication, such reference shall
be deemed to include authentication and delivery on behalf of the Trustee by an Authenticating
Agent and a certificate of authentication executed on behalf of the Trustee by an Authenticating
Agent. Each Authenticating Agent shall be acceptable to the Company and shall at all times be a
corporation organized and doing business under the laws of the United States of America, any State
thereof or the District of Columbia, authorized under such laws to act as Authenticating Agent,
having a combined capital and surplus of not less than $50,000,000 and subject to supervision or
examination by Federal or State authority. If such Authenticating Agent publishes reports of
condition at least annually, pursuant to law or to the requirements of said supervising or
examining authority, then for the purposes of this Section, the combined capital and surplus of
such Authenticating Agent 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 an Authenticating Agent shall
cease to be eligible in accordance with the provisions of this Section, such Authenticating Agent
shall resign immediately in the manner and with the effect specified in this Section.

     Any corporation into which an Authenticating Agent may be merged or converted or with which it
may be consolidated, or any corporation resulting from any merger, conversion or consolidation to
which such Authenticating Agent shall be a party, or any corporation succeeding to all or
substantially all the corporate agency or corporate trust business of an Authenticating Agent,
shall continue to be an Authenticating Agent, provided such corporation shall be otherwise eligible
under this Section, without the execution or filing of any paper or any further act on the part of
the Trustee or the Authenticating Agent.

     An Authenticating Agent may resign at any time by giving written notice thereof to the Trustee
and to the Company. The Trustee may at any time terminate the agency of an Authenticating Agent by
giving written notice thereof to such Authenticating Agent and to the Company. Upon receiving such
a notice of resignation or upon such a termination, or in case at any time such Authenticating
Agent shall cease to be eligible in accordance with the provisions of this Section, the Trustee may
appoint a successor Authenticating Agent which shall be
acceptable to the Company and shall deliver written notice of such appointment by first-class
mail, postage prepaid, to all Holders as their names and addresses appear in the Security Register,
or by such other means reasonably acceptable to such Holders. Any successor Authenticating Agent
upon acceptance of its appointment hereunder shall become vested with all the rights, powers and
duties of its predecessor hereunder, with like effect as if originally named as an Authenticating
Agent. No successor Authenticating Agent shall be appointed unless eligible under the provisions
of this Section.

60

 

     The Trustee agrees to pay to each Authenticating Agent from time to time reasonable
compensation for its services under this Section, and the Trustee shall be entitled to be
reimbursed for such payments by the Company, subject to the provisions of Section 6.07.

     If an appointment is made pursuant to this Section, the Securities may have endorsed thereon,
in addition to the Trustee’s certificate of authentication, an alternative certificate of
authentication in the following form:

	 	 	 	 	 
	 	 	This is one of the Securities described in the
	 	 	within-mentioned Indenture.
	 
	 	 	 	 
	 	 	The Bank of New York Trust Company, National
	 	 	Association
	 	 	as Trustee
	 
	 	 	 	 
	 

	 	By:	 	 
	 

	 	 	 	 
	 

	 	Name:	 	 
	 

	 	 	 	 
	 	 	Title: Authenticating Agent
	 
	 	 	 	 
	 

	 	By:	 	 
	 

	 	 	 	 
	 

	 	Name:	 	 
	 

	 	 	 	 
	 	 	Title: Authorized Officer

     Section 6.15. USA Patriot Act.

     In order to comply with laws, rules, regulations and executive orders in effect from time to
time applicable to banking institutions, including those relating to the funding of terrorist
activities and money laundering (“Applicable Law”), The Bank of New York is required to
obtain, verify and record certain information relating to individuals and entities which

     (c) Every Holder of Securities, by receiving and holding the same, agrees with the Company and
the Trustee that neither the Company nor the Trustee nor any agent of either of them shall be held
accountable by reason of any disclosure of information as to names and addresses of Holders made

requirements of Section 314(a) of the Trust Indenture Act; provided that any such information,
documents or reports filed or furnished with the Commission pursuant to its Electronic Data
Gathering, Analysis and Retrieval (or EDGAR) system shall be deemed to be filed with the Trustee as
of the time such information, documents or reports are filed or furnished via EDGAR.

     If at any time the Company is not required to file reports with the Commission pursuant to
Sections 13 or 15(d) of the Exchange Act, the Company shall, so long as any of the Securities
shall, at such time, constitute “restricted securities” within the meaning of Rule 144(a)(3) under
the Securities Act, promptly furnish to the Trustee, each Holder, beneficial owner or prospective
purchaser of such Securities or the Common Stock issuable upon conversion thereof, the information
required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act to facilitate the
resale of such Securities pursuant to Rule 144A under the Securities Act and to take such other
actions as any such Person may reasonably request, all to the extent required from time to time to
enable such Person to sell its Securities or Common Stock issuable upon conversion thereof in
accordance with Rule 144A under the Securities Act, as such rule may be amended from time to time.

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

which the obligor on the Securities was organized immediately before giving effect to the
transaction or series of transactions, (a) the Successor delivers to the Trustee an Opinion
of Counsel stating that (1) the obligations of the Successor are enforceable under the laws
of the new jurisdiction of its formation subject to customary exceptions and (2) the Holders
of Securities will not recognize any income, gain or loss for United States Federal income

United States Federal income tax on the same amount and in the same manner and at the same
times as would have been the case if such transaction or series of transactions had not
occurred; (b) the Successor agrees in writing to submit to jurisdiction to the competent
courts of the State of New York or the federal district court sitting in The City of New
York and appoints an agent in the State of New York for the service of process, each under

and

     (4) in the case of clause (1)(b) above, the Successor delivers to the Trustee an

adversely
affected by such change. Such determination shall be conclusive and binding on all present and
future Holders.

     Section 9.02. Supplemental Indentures with Consent of Holders.

Section 9.01(a).

     It shall not be necessary for any Act of Holders under this Section to approve the particular
form of any proposed supplemental indenture, but it shall be sufficient if such Act shall approve

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 9.05. Conformity with Trust Indenture Act.

     Every supplemental indenture executed pursuant to this Article shall conform to the
requirements of the Trust Indenture Act.

     Section 9.06. Reference in Securities to Supplemental Indentures.

     Securities authenticated and delivered after the execution of any supplemental indenture
pursuant to this Article may, and shall if required by the Trustee, bear a notation in form
approved by the Trustee as to any matter provided for in such supplemental indenture. If the
Company shall so determine, new Securities so modified as to conform, in the opinion of the Trustee
and the Company, to any such supplemental indenture may be prepared and executed by the Company and
authenticated and delivered by the Trustee in exchange for Outstanding Securities.

COVENANTS

     Section 10.01. Payment of Principal and Interest.

     The Company will duly and punctually pay the principal of and Interest on the Securities in
accordance with the terms of the Securities and this Indenture.

     Section 10.02. Maintenance of Office or Agency.

     The Company will maintain an office or agency in the United States (which shall be initially
the Trustee’s Corporate Trust Office) where Securities may be presented or surrendered for payment,
where Securities may be surrendered for registration of transfer or exchange, where Securities may
be surrendered for conversion and where notices and demands to or upon the Company in respect of
the Securities and this Indenture may be served. The Company will give prompt written notice to
the Trustee of any change in the location of 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 of the Trustee, and the Company hereby
appoints the Trustee as its agent to receive all such presentations, surrenders, notices and
demands.

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

     Section 10.03. Money for Security Payments to Be Held in Trust.

     If the Company shall at any time act as its own Paying Agent, it will, on or before each due
date of the principal of or Interest on any of the Securities, segregate and hold in trust for the
benefit of the Persons entitled thereto a sum sufficient to pay the principal or Interest so
becoming due until such sums shall be paid to such Persons or otherwise disposed of as herein
provided and will promptly notify the Trustee of its action or failure so to act in that regard.

     Whenever the Company shall have one or more Paying Agents, it will, prior to each due date of
the principal of or Interest on any Securities, deposit with a Paying Agent a sum sufficient to pay
such amount so becoming due, such sum to be held as provided by the Trust Indenture Act, and
(unless such Paying Agent is the Trustee) the Company will promptly notify the Trustee of its
action or failure so to act in that regard.

     The Company will cause each Paying Agent other than the Trustee to execute and deliver to the
Trustee an instrument in which such Paying Agent shall agree with the Trustee, subject to the
provisions of this Section, that such Paying Agent will (i) comply with the provisions of the Trust
Indenture Act applicable to it as a Paying Agent and (ii) during the continuance of any

68

 

default by
the Company (or any other obligor upon the Securities) in the making of any payment in respect of
the Securities and upon written request of the Trustee, forthwith pay to the Trustee all sums held
in trust by such Paying Agent for payment in respect of the Securities and to account for any
monies already paid.

     The Company may at any time, for the purpose of obtaining the satisfaction and discharge of
this Indenture or for any other purpose, pay, or by Company Order direct any Paying Agent to pay,
to the Trustee all sums held in trust by the Company or such Paying Agent, such sums to be held by
the Trustee upon the same trusts as those upon which such sums were held by the Company or such
Paying Agent; and, upon such payment by any Paying Agent to the Trustee, such Paying Agent shall be
released from all further liability with respect to such sum.

     Subject to any applicable abandoned property law, any money deposited with the Trustee or any
Paying Agent, or then held by the Company, in trust for the payment of the principal of or Interest
on any Security and remaining unclaimed for two years after such principal or Interest
has become due and payable shall be paid to the Company on Company Request, or (if then held
by the Company) shall be discharged from such trust; and the Holder of such Security 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 all liability
of the Company as trustee thereof, shall thereupon cease; provided, however, that the Trustee or
such Paying Agent, before being required to make any such repayment, may at the expense of the
Company cause to be published once, in a newspaper published in the English language, customarily
published on each Business Day and of general circulation in New York, New York, notice that such
money remains unclaimed and that, after a date specified therein, which shall not be less than 30
days from the date of such publication, any unclaimed balance of such money then remaining will be
repaid to the Company.

     Section 10.04. Statement by Officers as to Default.

     The Company shall deliver to the Trustee, within 120 days after the end of each fiscal year of
the Company, a statement signed by the principal executive officer, principal financial officer or
principal accounting officer of the Company, which need not constitute an Officer’s Certificate,
stating that in the course of performance by the signing Officer of his duties as such Officer of
the Company he would normally obtain knowledge of the keeping, observing, performing and fulfilling
by the Company of its obligations under this Indenture, and further stating that to the best of his
knowledge the Company has kept, observed, performed and fulfilled each and every covenant contained
in this Indenture and is not in default in the performance or observance of any of the terms,
provisions and conditions hereof (or, if a default or Event of Default shall have occurred,
describing all such defaults or Events of Default of which such Officer may have knowledge and what
action the Company is taking or proposes to take with respect thereto).

     In addition, the Company will deliver to the Trustee, within 30 days after the occurrence
thereof, written notice of any events that would constitute a default or an Event of Default, the
status of those events and what action the Company is taking or propose to take in respect thereof.

69

 

     Section 10.05. Existence.

     Subject to Article 8, the Company will do or cause to be done all things necessary to
preserve and keep in full force and effect its existence.

     Section 10.06. Additional Interest.

     The Company shall pay Additional Interest if at any time during the period beginning six
months from the Issue Date of the Initial Securities (or, if later, the date on which the Company
delivers additional Securities to the Initial Purchasers pursuant to the exercise of their option
to purchase additional Securities) and ending 12 months from such date, the Company fails to
timely file any report that the Company is required to file with the SEC pursuant to Section 13 or
15(d) of the Exchange Act, as applicable (other than reports on Form 8-K); provided, that the
Company shall have 14 days, in the aggregate, to cure all such missed filings without paying such
Additional Interest. The Additional Interest shall be payable on the Interest Payment Date
following the Company’s failure to file that gives rise to such Additional Interest. If at any
time Additional Interest becomes payable, the Company shall promptly deliver to the Trustee a
certificate executed by an Officer of the Company to that effect and stating (i) the amount of such
Additional Interest that is payable and (ii) the date on which such Additional Interest is payable.
Unless and until a Responsible Officer of the Trustee receives such a certificate, the Trustee may
assume without inquiry that no Additional Interest is payable. If the Company has paid Additional
Interest directly to the Persons entitled to such Additional Interest, the Company shall promptly
deliver to the Trustee such a certificate setting forth the particulars of such payment. The
Company’s obligation to pay Additional Interest in accordance with this Section shall be in
addition to the Company’s obligation, if any, to pay an Extension Fee in accordance with
Section 5.02.

ARTICLE 11

OPTIONAL REDEMPTION; REPURCHASE AT OPTION OF THE HOLDER

     Section 11.01. Right to Redeem; Notice to Trustee.

     At any time on or after June 6, 2013, the Company may redeem any or all of the Securities,
except for the Securities that the Company is required to repurchase pursuant to
Section 11.08 and Section 11.09, in cash at the Redemption Price.

     The redemption price will equal 100% of the Accreted Principal Amount of the Securities being
redeemed, plus accrued and unpaid Interest, if any, to, but not including, the Redemption Date (the
“Redemption Price”); provided, however, that, if the Redemption Date is after a Regular Record Date
and on or prior to the corresponding Interest Payment Date, the Company shall pay the full amount
of accrued and unpaid Interest payable on such Interest Payment Date to the Holder of record at the
close of business on the corresponding Regular Record Date.

     If the Company elects to redeem Securities pursuant to this Section 11.01, it shall
notify the Trustee at least 45 calendar days prior to the Redemption Date, as fixed by the Company
(unless a shorter notice shall be satisfactory to the Trustee), of the Redemption Date and the
Accreted Principal Amount of Securities to be redeemed.

70

 

     Notwithstanding the foregoing, the Company may not redeem any Securities if the Company has
failed to pay any Interest due on the Securities and such failure to pay is continuing.

     Section 11.02. Selection of the Securities to Be Redeemed.

     If fewer than all of the Outstanding Securities are to be redeemed, the Trustee will select
the Securities to be redeemed in Original Principal Amounts of $1,000 or multiples of $1,000 by
lot, pro rata or by another method the Trustee considers reasonable. Provisions of this Indenture
that apply to Securities called for redemption also apply to portions of Securities called for
redemption. If any Security selected for partial redemption is converted in part before termination
of the conversion right with respect to the portion of the Security so selected, the converted
portion of such Security shall be deemed to be taken from the portion selected for redemption.
Securities which have been converted during a selection of Securities to be redeemed shall be
treated by the Trustee as Outstanding for the purpose of such selection.

     Section 11.03. Notice of Redemption.

     Not more than 60 calendar days but not less than 30 calendar days prior to the Redemption
Date, the Company shall give a notice of redemption to all record Holders at their addresses set
forth in the Security Register of the Security Registrar.

     The notice shall identify the Securities to be redeemed and shall state:

     (a) that the Holder has a right to convert the Securities called for redemption, and the
Conversion Rate then in effect;

     (b) the Redemption Date;

     (c) the Redemption Price;

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

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

     (f) that Holders who wish to convert Securities must surrender such Securities for conversion
no later than 5:00 p.m., New York City time, on the Business Day immediately preceding the
Redemption Date and must satisfy the other requirements set forth in Article 12;

     (g) that, unless the Company defaults in making the payment of the Redemption Price, Interest
on Securities called for redemption shall cease to accrue, and Accreted Principal Amount of such
Securities will cease to accrete, on and after the Redemption Date and subject to the provisions of
Section 11.01 and Section 11.04, the only remaining right of the Holder shall be to
receive payment of the Redemption Price upon presentation and surrender to a Paying Agent of the
Securities; and

71

 

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

     If any of the Securities to be redeemed is in the form of a Global Security, then the Company
shall modify such notice to the extent necessary to accord with the procedures of the Depositary
applicable to redemptions. At the Company’s written request, the Trustee shall give the notice of
redemption in the Company’s name and at the Company’s expense.

     Section 11.04. Effect of Notice of Redemption.

     Once notice of redemption is mailed, Securities called for redemption become due and payable
on the Redemption Date and at the Redemption Price stated in the notice except for Securities that
are converted in accordance with the terms of this Indenture. Upon presentation and surrender to a
Paying Agent, Securities called for redemption shall be paid in cash at the Redemption Price stated
in the notice.

     Section 11.05. Deposit of Redemption Price.

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

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

     Section 11.06. Securities Redeemed in Part.

     Upon presentation and surrender of a Security that is redeemed in part, the Company shall
execute and, upon receipt of a Company Order, the Trustee shall authenticate and deliver to the
Holder, without charge, new Securities of authorized denominations as requested by such Holder in
aggregate Accreted Principal Amount equal to, and in exchange for, the unredeemed portion of the
Security surrendered.

72

 

     Section 11.07. No Redemption of Securities Upon Occurrence of Acceleration.

     Notwithstanding anything herein to the contrary, the Company will not redeem any Securities on
any date if the Accreted Principal Amount of the Securities has been accelerated, and such
acceleration has not been rescinded, on or prior to the Redemption Date (except in the case of an
acceleration resulting from a default by the Company in the payment of the Redemption Price with
respect to such Securities).

     Section 11.08. Repurchase of Securities at the Option of Holders.

     (a) Optional Put. (i)  On June 1, 2013, June 1, 2018, June 1, 2023, June 1, 2028 and June 1,
2033 (each, an “Optional Put Repurchase Date”), each Holder shall have the right, at such Holder’s
option, to require the Company to repurchase all of such Holder’s Securities or any portion of the
Original Principal Amount thereof that is equal to $1,000 or an integral multiple of $1,000, for
cash at a repurchase price equal to 100% of the Accreted Principal Amount thereof, together with
accrued and unpaid Interest thereon to, but excluding, such Optional Put Repurchase Date (the
“Optional Put Repurchase Price”) (subject to satisfaction by or on behalf of the Holder of the
requirements set forth in Section 11.08(a)), unless such Optional Put Repurchase Date falls
after a Regular Record Date and on or prior to the corresponding Interest Payment Date, in which
case the Company shall pay the full amount of accrued and unpaid Interest payable on such Interest
Payment Date to the Holder of record at 5:00 p.m., New York City time, on the corresponding Regular
Record Date.

          (ii) No later than 20 Business Days prior to each Optional Put Repurchase Date, the Company
shall give notice of the repurchase right under Section 11.08(a)(i) (an “Optional Put
Repurchase Offer”) to all record Holders at their addresses set forth in the Security Register of
the Security Registrar (and to beneficial owners as required by applicable law). The notice shall
include a form of notice to be completed by the Holder and returned to the Company in the event
that the Holder elects such right to such repurchase (the “Optional Put Repurchase Notice”) and
shall briefly state, as applicable:

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

               (B) the Optional Put Repurchase Date;

               (C) the Optional Put Repurchase Price;

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

               (E) the Conversion Rate;

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

               (G) that the Securities as to which an Optional Put Repurchase Notice has been given may be
converted if they are otherwise convertible pursuant to Article 12 only if

73

 

the Optional Put
Repurchase Notice has been withdrawn in accordance with the terms of this Indenture;

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

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

               (J) the procedures the Holder must follow to exercise its put right under this
Section 11.08(a);

               (K) the procedures for withdrawing an Optional Put Repurchase Notice;

               (L) that, unless the Company defaults in making payment of such Optional Put Repurchase Price,
Interest on Securities surrendered for repurchase by the Company will cease to accrue, and Accreted
Principal Amount of such Securities will cease to accrete, on and after the Optional Put Repurchase
Date; and

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

     At the Company’s request, the Trustee shall give the Optional Put Repurchase Offer in the
Company’s name and at the Company’s expense; provided, however, that the Company makes such request
at least three Business Days (unless a shorter period shall be satisfactory to the Trustee) prior
to the date by which such Optional Put Repurchase Offer must be given to the Holder in accordance
with this Section 11.08(a)(ii); provided, further, that the text of the Optional Put
Repurchase Offer shall be prepared by the Company.

          (iii) A Holder may exercise its right specified in Section 11.08(a)(ii) upon delivery
of a properly completed Optional Put Repurchase Notice to the Paying Agent at any time during the
period beginning at 9:00 a.m., New York City time, on the date that is 20 Business Days immediately
preceding the relevant Optional Put Repurchase Date until 5:00 p.m., New York City time, on the
Business Day immediately preceding such Optional Put Repurchase Date, stating:

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

               (B) the portion of the Original Principal Amount of Securities to be repurchased, which
portion must be $1,000 or an integral multiple of $1,000 thereof; and

               (C) that the Securities shall be repurchased by the Company pursuant to the applicable
provisions of the Securities and this Indenture.

74

 

     The book-entry transfer or delivery of such Security to the Paying Agent with, or at any time
after delivery of, the Optional Put Repurchase Notice (together with all necessary endorsements) at
the offices of the Paying Agent shall be a condition to the receipt by the Holder of the Optional
Put Repurchase Price therefor; provided, however, that such Optional Put Repurchase Price shall be
so paid pursuant to this Section 11.08(a) only if the Security so delivered to the Paying
Agent shall conform in all respects to the description thereof in the related Optional Put
Repurchase Notice.

     The Company shall repurchase from the Holder thereof, pursuant to this
Section 11.08(a), a portion of a Security specified in the Optional Put Repurchase Notice,
so long as the Original Principal Amount of such portion is $1,000 Original Principal Amount or an
integral multiple of $1,000 Original Principal Amount. Provisions of this Indenture that apply to
the repurchase of all of a Security also apply to the repurchase of such portion of such Security.

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

     (b) Effect of Optional Put Repurchase Notice. Upon receipt by the Paying Agent of the Optional
Put Repurchase Notice specified in Section 11.08(a)(iii), the Holder of the Security in
respect of which such Optional Put Repurchase Notice was given shall (unless such Optional Put
Repurchase Notice is withdrawn as specified in the following paragraph) thereafter be entitled to
receive solely the Optional Put Repurchase Price with respect to such Security. Such Optional Put
Repurchase Price shall be paid to such Holder, subject to receipt of cash by the Paying Agent from
the Company, on the later of (1) the Optional Put Repurchase Date with respect to such Security
(provided the conditions in Section 11.08(a)(iii) have been satisfied) and (2) the time of
book-entry transfer or delivery of such Security to the Paying Agent by the Holder thereof in the
manner required by Section 11.08(a)(iii). Securities in respect of which an Optional Put
Repurchase Notice has been given by the Holder thereof may not be converted pursuant to
Article 12 on or after the date of the delivery of such Optional Put Repurchase Notice
unless such Optional Put Repurchase Notice has first been validly withdrawn as specified in the
following paragraph.

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

          (i) the Original Principal Amount of such Security with respect to which such notice of
withdrawal is being submitted;

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

          (iii) the Original Principal Amount, if any, of such Security which remains subject to the
Optional Put Repurchase Notice, which portion must be in Original Principal amounts of $1,000 or an
integral multiple of $1,000;

75

 

provided, however, that with respect to Global Securities, the withdrawal notice must comply with
the Applicable Procedures.

     (c) Deposit of Optional Put Repurchase Price. Prior to 1:00 p.m., New York City time, on the
applicable Optional Put Repurchase Date, the Company shall deposit with the Paying Agent (or if the
Company or a Subsidiary is acting as the Paying Agent, shall segregate and hold in trust as
provided in Section 10.03) an amount of cash (in immediately available funds if deposited
on such Business Day) sufficient to pay the aggregate Optional Put Repurchase Price of all the
Securities or portions thereof which are to be repurchased on such Optional Put Repurchase Date.

     If the Paying Agent (other than the Company or a Subsidiary) holds, in accordance with the
terms hereof, at 1:00 p.m., New York City time, on the applicable Optional Put Repurchase Date,
cash sufficient to pay the Optional Put Repurchase Price of any Securities for which an Optional
Put Repurchase Notice has been tendered and not withdrawn pursuant to Section 11.08(b),
then, on and after such Optional Put Repurchase Date, such Securities will cease to be Outstanding,
the Accreted Principal Amount shall cease to accrete and Interest, if any, on such Securities will
cease to accrue, whether or not such Securities are delivered to the Paying Agent, and the rights
of the Holders in respect thereof shall terminate (other than the right to receive the Optional Put
Repurchase Price upon delivery of such Securities, together with any necessary endorsement) and the
repurchased Securities shall be cancelled.

     (d) Securities Repurchased in Part. Any certificated Security which is to be repurchased only
in part shall be surrendered at the office of the Paying Agent (with, if the Company or the Trustee
so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the
Company and the Trustee duly executed by, the Holder thereof or such Holder’s attorney duly
authorized in writing) and the Company shall execute and upon receipt of a Company Order the
Trustee shall authenticate and deliver to the Holder of such Security, without charge, new
Securities, of any authorized denomination as requested by such Holder in aggregate Accreted
Principal Amount equal to, and in exchange for, the portion of the Accreted Principal Amount of the
Security so surrendered which is not repurchased.

     (e) Repayment to the Company. The Paying Agent shall return to the Company any cash that
remains unclaimed for two years, together with Interest, if any, thereon, held by it for the
payment of the Optional Put Repurchase Price; provided, however, to the extent that the aggregate
amount of cash deposited by the Company pursuant to Section 11.08(c) exceeds the aggregate
Optional Put Repurchase Price of the Securities or portions thereof which the Company is obligated
to repurchase on the Optional Put Repurchase Date, then, promptly after the Optional Put Repurchase
Date, the Paying Agent shall return any such excess to the Company.

     (f) No Repurchase Upon Acceleration. Notwithstanding anything herein to the contrary, there
shall be no purchase of any Securities pursuant to this Section 11.08 if the Accreted
Principal Amount of the Securities has been accelerated, and such acceleration has not been
rescinded, on or prior to the Optional Put Repurchase Date (except in the case of an acceleration
resulting from a default by the Company in the payment of the Optional Put Repurchase Price with
respect to such Securities).

76

 

     Section 11.09. Repurchase at the Option of the Holder Upon a Fundamental Change.

     (a) If a Fundamental Change occurs at any time, then each Holder shall have the right, at such
Holder’s option, to require the Company to repurchase all of such Holder’s Securities or any
portion of the Original Principal Amount thereof that is equal to $1,000 or an integral multiple of
$1,000, for cash on the date (the “Fundamental Change Repurchase Date”) specified by the Company
that is not less than 15 calendar days and not more than 35 calendar days after the date of the
Fundamental Change Repurchase Right Notice, at a repurchase price equal to 100% of the Accreted
Principal Amount thereof, together with accrued and unpaid Interest thereon to, but excluding, the
Fundamental Change Repurchase Date (the “Fundamental Change Repurchase Price”) (subject to
satisfaction by or on behalf of the Holder of the requirements set forth in
Section 11.09(a)) unless such Fundamental Change Repurchase Date falls after a Regular
Record Date and on or prior to the corresponding Interest Payment Date, in which case the Company
shall pay the full amount of accrued and unpaid Interest payable on such Interest Payment Date to
the Holder of record at 5:00 p.m., New York City time, on the corresponding Regular Record Date.

     Notwithstanding the foregoing, Holders shall not have the right to require the Company to
repurchase any Securities under this Section 11.09 based on a Fundamental Change under
clause (1), (2) or (3) of the definition thereof (and the Company shall not be required to deliver
the Fundamental Change Repurchase Right Notice incidental thereto), if at least 90% of the
consideration paid for the Common Stock (excluding cash payments for fractional shares and cash
payments made pursuant to dissenters’ appraisal rights and cash dividends) in connection with a
transaction otherwise constituting a Fundamental Change under clause (1), (2) or (3) of the
definition thereof consists of shares of common equity traded on any of the New York Stock
Exchange, the American Stock Exchange, the NASDAQ Global Market or the NASDAQ Global Select Market
(or any of their respective successors) (or will be so traded immediately following such
transaction or transactions) and, as a result of such transaction or transactions, the Securities
become convertible into such shares of such common equity pursuant to Section 12.10 (or cash or a
combination of cash and such shares of such common equity pursuant to Section 12.10, if the Company
so elects or has so elected).

     Repurchases of Securities under this Section 11.09 shall be made, at the option of the
Holder thereof, upon:

          (i) if the Securities are held in certificated form, delivery to the Trustee (or other Paying
Agent appointed by the Company) by a Holder of a duly completed notice (the “Fundamental Change
Repurchase Notice”) in the form set forth on the reverse of the Security or, if the Securities are
held in global form, a notice that complies with the Applicable Procedures, prior to 5:00 p.m.,
New York City time, on the Business Day immediately preceding the Fundamental Change Repurchase
Date; and

          (ii) delivery or book-entry transfer of the Securities to the Trustee (or other Paying Agent
appointed by the Company) at any time after delivery of the Fundamental Change Repurchase Notice
(together with all necessary endorsements) at the Corporate Trust Office of
the Trustee (or other Paying Agent appointed by the Company), such delivery being a condition
to receipt by the Holder of the Fundamental Change Repurchase Price therefor; provided that

77

 

such
Fundamental Change Repurchase Price shall be so paid pursuant to this Section 11.09 only if
the Security so delivered to the Trustee (or other Paying Agent appointed by the Company) shall
conform in all respects to the description thereof in the related Fundamental Change Repurchase
Notice.

     The Fundamental Change Repurchase Notice shall state:

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

               (B) the portion of the Original Principal Amount of Securities to be repurchased, which must
be $1,000 or an integral multiple of $1,000 thereof; and

               (C) that the Securities shall be repurchased by the Company pursuant to the applicable
provisions of the Securities and this Indenture.

     Any purchase by the Company contemplated pursuant to the provisions of this
Section 11.09 shall be consummated by the delivery of the consideration to be received by
the Holder promptly following the later of the Fundamental Change Repurchase Date and the time of
the book-entry transfer or delivery of the Security.

     The Trustee (or other Paying Agent appointed by the Company) shall promptly notify the Company
of the receipt by it of any Fundamental Change Repurchase Notice or written notice of withdrawal
thereof in accordance with the provisions of subsection (c) of this Section 11.09.

     Any Security that is to be repurchased only in part shall be surrendered to the Trustee (with,
if the Company or the Trustee so requires, due endorsement by, or a written instrument of transfer
in form satisfactory to the Company and the Trustee duly executed by the Holder thereof or his
attorney duly authorized in writing), and the Company shall execute, and, upon receipt of a Company
Order, the Trustee shall authenticate and make available for delivery to the Holder of such
Security without service charge, a new Security or Securities, containing identical terms and
conditions, each in an authorized denomination in aggregate principal amount equal to and in
exchange for the unrepurchased portion of the principal of the Security so surrendered.

     (b) After the occurrence of a Fundamental Change, but on or before the 10th calendar day after
the Effective Date of such Fundamental Change, the Company shall provide to all Holders of record
of the Securities and the Trustee and Paying Agent a notice (the “Fundamental Change Repurchase
Right Notice”) of the occurrence of such Fundamental Change and of the repurchase right, if any, at
the option of the Holders arising as a result thereof. Such mailing shall be by first class mail.

     Each Fundamental Change Repurchase Right Notice shall specify (if applicable):

	 	(i)	 	the events causing the Fundamental Change;
	 
	 	(ii)	 	the date of the Fundamental Change;

78

 

          (iii) the last date on which a Holder may exercise its repurchase rights under
Section 11.09, if applicable;

          (iv) the Fundamental Change Repurchase Price, if applicable;

          (v) the Fundamental Change Repurchase Date, if applicable;

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

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

          (viii) that the Securities with respect to which a Fundamental Change Purchase 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; and

          (ix) the procedures the Holder must follow to require the Company to purchase its Securities
under Section 11.09, if applicable.

     (c) 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 and the Trustee in accordance with the
Fundamental Change Repurchase Right Notice at any time prior to 5:00 p.m., New York City time, on
the Business Day immediately preceding the Fundamental Change Repurchase Date, specifying:

          (i) the Original Principal Amount of such Security with respect to which such notice of
withdrawal is being submitted;

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

          (iii) the Original Principal Amount, if any, of such Security which remains subject to the
Fundamental Change Repurchase Notice, which portion must be in Original Principal amounts of $1,000
or an integral multiple of $1,000;

provided, however, that with respect to Global Securities, the notice must comply with the
Applicable Procedures.

     (d) Prior to 1:00 p.m., New York City time, on the Fundamental Change Repurchase Date, the
Company shall deposit with the Paying Agent (or if the Company or a Subsidiary is acting as the
Paying Agent, shall segregate and hold in trust as provided in Section 10.03) an amount of
cash (in immediately available funds if deposited on such Business Day) sufficient to pay the
aggregate Fundamental Change Repurchase Price of all the Securities or portions thereof which are
to be repurchased on such Fundamental Change Repurchase Date. Such Fundamental Change Repurchase
Price shall be paid to a Holder surrendering Securities for repurchase pursuant to a Fundamental
Change Repurchase Notice, subject to receipt of cash by the Paying Agent from the Company, on the
later of (1) the Fundamental Change Repurchase Date with

79

 

respect to such Security (provided the conditions in Section 11.09(a) have been
satisfied by such Holder) and (2) the time of book-entry transfer or delivery of such Security to
the Paying Agent by the Holder thereof in the manner required by Section 11.09(a).
Securities in respect of which a Fundamental Change Repurchase Notice has been given by the Holder
thereof may not be converted pursuant to Article 12 on or after the date of the delivery of
such Fundamental Change Repurchase Notice unless such Fundamental Change Repurchase Notice has
first been validly withdrawn pursuant to Section 11.09(c).

     (e) If the Paying Agent (other than the Company or a Subsidiary) holds, in accordance with the
terms hereof, at 1:00 p.m., New York City time, on the applicable Fundamental Change Repurchase
Date, cash sufficient to pay the Fundamental Change Repurchase Price of any Securities for which a
Fundamental Change Repurchase Notice has been tendered and not withdrawn pursuant to
Section 11.09(c), then, on and after such Fundamental Change Repurchase Date, such
Securities will cease to be Outstanding, the Accreted Principal Amount shall cease to accrete and
Interest, if any, on such Securities will cease to accrue, whether or not such Securities are
delivered to the Paying Agent, and the rights of the Holders in respect thereof shall terminate
(other than the right to receive the Fundamental Change Repurchase Price upon delivery of such
Securities, together with any necessary endorsement) and the repurchased Securities shall be
cancelled.

     (f) Notwithstanding anything herein to the contrary, there shall be no purchase of any
Securities pursuant to this Section 11.09 if the Accreted Principal Amount of the
Securities has been accelerated, and such acceleration has not been rescinded, on or prior to the
Fundamental Change Repurchase Date (except in the case of an acceleration resulting from a default
by the Company in the payment of the Fundamental Change Repurchase Price with respect to such
Securities).

     Section 11.10. Covenant to Comply with Securities Laws upon Repurchase of Securities. In
connection with any repurchase of the Securities pursuant to Section 11.08 or
Section 11.09, the Company shall:

     (a) comply with the provisions of any tender offer rules under the Exchange Act that may then
be applicable; and

     (b) otherwise comply with all federal and state securities laws.

     To the extent that the provisions of any securities laws or regulations conflict with the
provisions of Section 11.08 or Section 11.09, the Company’s compliance with such
laws and regulations shall not in and of itself cause a breach of its obligations under said
Section 11.08 or Section 11.09.

     Section 11.11. Purchase of Securities.

     (a) The Company may at any time repurchase or otherwise acquire Securities in the open market
or in negotiated transactions without prior notice to Holders. Any such acquisition
shall not operate as or be deemed for any purpose to be a redemption of the indebtedness
represented by such Securities. Any Securities purchased or acquired by the Company may be

80

 

delivered to the Trustee and, upon such delivery, the indebtedness represented thereby shall be
deemed to be satisfied. Section 3.13 shall apply to all Securities so delivered.

ARTICLE 12

CONVERSION OF SECURITIES

     Section 12.01. Conversion Privilege and Conversion Rate.

     (a) Subject to the conditions described in clauses (i), (ii), (iii)
and (iv) below, and upon compliance with the provisions of this Article 12, a
Holder shall have the right, at such Holder’s option, to surrender for conversion all or any
portion (if the portion to be converted is $1,000 in Original Principal Amount or an integral
multiple thereof) of any Securities at any time prior to 5:00 p.m., New York City time, on the
Scheduled Trading Day immediately preceding March 1, 2013, into shares of Common Stock (or, at the
election of the Company, cash or a combination of cash and shares of Common Stock as described
herein) at a rate of 19.9695 shares of Common Stock (subject to adjustment by the Company as
provided in Section 12.01(e) and Section 12.05 hereof) per $1,000 in Original
Principal Amount of the Securities (the “Conversion Rate”) under the circumstances and during the
periods set forth below. On and after March 1, 2013, regardless of the conditions described in
clauses (i), (ii), (iii) and (iv) below, and upon compliance with
the provisions of this Article 12, a Holder shall have the right, at such Holder’s option,
to surrender for conversion all or any portion (if the portion to be converted is $1,000 in
Original Principal Amount or an integral multiple thereof) of any Securities at the applicable
Conversion Rate at any time prior to 5:00 p.m., New York City time, on the Scheduled Trading Day
immediately preceding the Maturity Date.

          (i) The Securities shall be convertible prior to March 1, 2013, during the five Business Day
period after any five consecutive Trading Day period (as used in this Section 12.01(a)(i),
the “Measurement Period”) in which the Trading Price per $1,000 in Original Principal Amount of the
Securities for each Trading Day of such Measurement Period was less than 98% of the product of the
Last Reported Sale Price of the Common Stock on such Trading Day and the applicable Conversion Rate
in effect on such Trading Day, as determined by the Company and subject to compliance with the
procedures and conditions described below concerning the Company’s obligation to make such
determination (the “Trading Price Condition”). If a Holder provides the Company with written
notice which includes reasonable evidence that the Trading Price per $1,000 in Original Principal
Amount of the Securities would be less than 98% of the product of (a) the applicable Conversion
Rate of the Securities and (b) the Last Reported Sale Price of the Common Stock at such time, then
the Company shall determine the Trading Price beginning on the next Trading Day and on each
successive Trading Day until the date on which the Trading Price per $1,000 in Original Principal
Amount of the Securities is greater than or equal to 98% of the product of (a) the applicable
Conversion Rate of the Securities and (b) the Last Reported Sale Price of the Common Stock.
Furthermore, if the Company does not, when obligated to do so pursuant to this clause (i),
determine the Trading Price of the Securities, then the Trading Price per $1,000 in Original
Principal Amount of the
Securities shall be deemed to be less than 98% of the product of (a) the applicable Conversion
Rate of the Securities and (b) the Last Reported Sale Price of the Common Stock on such date.

81

 

          If the Trading Price Condition has been met in accordance with the foregoing, the Company
shall so notify the Holders of the Securities and the Trustee. If, at any time after the Trading
Price Condition has been met in accordance with the foregoing, the Trading Price per $1,000 in
Original Principal Amount of the Securities is greater than or equal to 98% of the product of
(a) the applicable Conversion Rate of the Securities and (b) the Last Reported Sale Price of the
Common Stock on such date, the Company shall so notify the Holders of the Securities and the
Trustee, and the Company shall have no further obligation to determine the Trading Price of the
Securities unless requested to do so again in writing pursuant to this Section 12.01(a)(i).

          (ii) The Securities shall be convertible prior to March 1, 2013, during any calendar quarter
after the calendar quarter ending June 30, 2008 (and only during such calendar quarter), if the
Last Reported Sale Price of the Common Stock for 20 or more Trading Days in a period of 30
consecutive Trading Days ending on the last Trading Day of the immediately preceding calendar
quarter exceeds 120% of the applicable Conversion Price in effect on the last Trading Day of the
immediately preceding calendar quarter. For each calendar quarter, the Company will determine if
the Securities are convertible as the result of the satisfaction of the condition in this
Section 12.01(a)(ii) in the preceding calendar quarter and the Company will promptly notify
the Holders and the Trustee if this condition was satisfied.

          (iii) In the event the Company calls the Securities for redemption pursuant to
Section 11.01, the Securities shall be convertible until 5:00 p.m., New York City time, on
the Business Day preceding the applicable Redemption Date (after which time the Holders’ right to
convert will expire unless the Company defaults in the payment of the applicable Redemption Price).

          (iv) The Securities shall be convertible prior to March 1, 2013, as provided in
subsections (b), (c) and (d) of this Section 12.01.

     (b) In the event that the Company elects to:

          (i) distribute to all or substantially all holders of Common Stock any rights or warrants
entitling them, for a period of not more than 60 calendar days after the date of such distribution,
to subscribe for or purchase shares of Common Stock at a price per share less than the average of
the Last Reported Sale Prices of the Common Stock for the 10 consecutive Trading Day period ending
on the Trading Day immediately preceding the declaration date of such distribution; or

          (ii) distribute to all or substantially all holders of Common Stock assets (including cash) or
debt securities of the Company or certain rights to purchase the Company’s securities which
distribution has a per share value (as determined by the Company’s Board of Directors) exceeding
10% of the average of the Last Reported Sale Prices of the Common Stock for the 10 consecutive
Trading Day period ending on the Trading Day immediately preceding the declaration date of such
distribution;

the Company shall notify Holders and the Trustee in writing with respect to any distribution
referred to in either clause (i) or (ii) above and of the resulting conversion
right no later than the

82

 

 25th Scheduled Trading Day prior to the Ex Date for such distribution.
Once the Company has given such notice, Holders may surrender the Securities for conversion at any
time until the earlier of (A) 5:00 p.m., New York City time, on the Business Day immediately
preceding the Ex Date for such distribution or (B) the date the Company announces that such
distribution will not take place, even if the Securities are not otherwise convertible at such
time. A Holder may not exercise this right if such Holder is permitted to participate (as a result
of holding the Securities) at the same time as holders of the Common Stock participate in any
distribution referred to in clause (i) or (ii) above as if such Holder held a
number of shares of Common Stock equal to the applicable Conversion Rate, multiplied by the
Original Principal Amount of Securities held by such Holder divided by $1,000, without having to
convert its Securities.

     (c) If an event constituting a Fundamental Change occurs, the Company shall notify the Holders
and the Trustee in writing of the occurrence of any such event on or before the date such event
occurs or becomes effective or, if later, within one Business Day after the date the Company
becomes aware of such occurrence or effectiveness. Once the Company has given such notice, a
Holder may surrender Securities for conversion at any time from the effective date of such event
until the later of (i) the Fundamental Change Repurchase Date corresponding to such event or (ii)
35 Scheduled Trading Days following the effective date of such event.

     (d) If the Company is a party to a combination, merger, recapitalization, reclassification,
binding share exchange or other similar transaction or sale or conveyance of all or substantially
all of its properties and assets, in each case pursuant to which the Common Stock would be
converted into or exchanged for cash, securities and/or other property and that does not also
constitute a Fundamental Change, then the Holders shall have the right to surrender Securities for
conversion at any time beginning 25 Scheduled Trading Days prior to the anticipated effective date
of such transaction and ending on the 35th Scheduled Trading Day following the effective date of
such transaction. The Company shall use its reasonable best efforts to notify Holders and the
Trustee in writing by the later of (i) the date that the Company publicly discloses any such
transaction and (ii) 25 Scheduled Trading Days prior to the anticipated effective date of such
transaction, and in any event no later than the actual effective date of any such transaction. The
Board of Directors shall determine the anticipated effective date of any such transaction, and such
determination shall be conclusive and binding on the Holders.

     (e) If a Holder elects to surrender Securities for conversion in connection with a Make-Whole
Fundamental Change, the Conversion Rate applicable to each $1,000 in Original Principal Amount of
Securities so converted shall be increased by an additional number of shares of Common Stock (the
“Additional Shares”) as described below, provided, however, that no increase shall be made in the
case a transaction constituting a Fundamental Change pursuant to clauses (1) or (2)
of the definition thereof if 90% or more of the consideration for the Common Stock (excluding cash
payments for fractional shares and cash payments made pursuant to dissenters’ appraisal rights and
cash dividends) in connection with such transaction consists of shares of common equity traded on
any of the New York Stock Exchange, the American Stock Exchange, the NASDAQ Global Market or the
NASDAQ Global Select Market (or any of their respective successors) (or will be so traded or quoted
immediately following such transaction)
and, as a result of such transaction or transactions, the Securities become convertible (to
the

83

 

extent otherwise convertible into shares of Common Stock) into such shares of such common
equity pursuant to Section 12.10.

     Settlement of Securities surrendered for conversion to which Additional Shares shall be added
to the Conversion Rate as provided in this subsection (e) shall be settled pursuant to
Section 12.02(e). For purposes of this subsection (e), a conversion shall be
deemed to be “in connection with” such Make-Whole Fundamental Change if such conversion occurs on
or after the effective date of such Make-Whole Fundamental Change and prior to 5:00 p.m., New York
City time, on the Business Day immediately preceding the related Fundamental Change Repurchase Date
for such Make-Whole Fundamental Change. The Company will notify Holders and the Trustee in writing
of the occurrence of any Make-Whole Fundamental Change applicable to this subsection (e) on
the effective date of such transaction.

          (i) The number of Additional Shares by which the applicable Conversion Rate will be increased
in the event of a Make-Whole Fundamental Change shall be determined by the Company by reference to
the table attached as Schedule A hereto, based on the Make-Whole Reference Date and the
Stock Price; provided, that if the actual Stock Price is between two Stock Price amounts in the
table or the Make-Whole Reference Date is between two Make-Whole Reference Dates in the table, the
number of Additional Shares by which the Conversion Rate will be increased shall be determined by a
straight-line interpolation between the number of Additional Shares set forth for the next higher
and next lower Stock Price amounts and the two nearest Make-Whole Reference Dates, as applicable,
based on a 365-day year; provided, further, that if (1) the Stock Price is greater than $250.00 per
share of Common Stock (subject to adjustment in accordance with clause (ii) below), no
adjustments will be made to the Conversion Rate, and (2) the Stock Price is less than $33.95 per
share (subject to adjustment in accordance with clause (ii) below), no adjustments will be
made to the Conversion Rate. Notwithstanding the foregoing, in no event shall the Conversion Rate
exceed 29.4550 shares of Common Stock per $1,000 in Original Principal Amount of Securities
(subject to adjustment in the same manner as set forth in Section 12.05). In addition, if
Holders convert their Securities prior to any effective date of any Make Whole Fundamental Change
and the related Make Whole Fundamental Change does not occur, Holders will not be entitled to an
increased Conversion Rate in connection with such conversion.

          (ii) The Stock Prices set forth in the first column of the table in Schedule A hereto
shall be adjusted by the Company as of any date on which the Conversion Rate of the Securities is
adjusted (except pursuant to this Section 12.01(e)). 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 applicable Conversion Rate in effect immediately prior to the 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 within the table shall be adjusted in the same manner as
the Conversion Rate as set forth in Section 12.05 (other than by operation of an adjustment
to the Conversion Rate by adding Additional Shares).

     Section 12.02. Exercise of Conversion Privilege; Settlement.

     (a) The Company shall settle Securities surrendered for conversion by delivering, as
applicable:

84

 

          (i) if the Company elects to satisfy the entire Conversion Obligation in shares of Common
Stock, on the third Scheduled Trading Day immediately following the Conversion Date, a number of
whole shares of Common Stock obtained by dividing the Original Principal Amount of Securities to be
converted by 1,000, and multiplying that quotient by the Conversion Rate in effect on the relevant
Conversion Date;

          (ii) if the Company elects to satisfy the entire Conversion Obligation in cash, on the third
Scheduled Trading Day immediately following the last day of the related Observation Period, for
each $1,000 in Original Principal Amount of Securities surrendered for conversion, cash in an
amount equal to the sum of the Daily Conversion Values for each of the 20 VWAP Trading Days during
the related Observation Period; or

          (iii) if the Company elects to satisfy the Conversion Obligation in a combination of cash and
shares of Common Stock, on the third Scheduled Trading Day immediately following the last day of
the related Observation Period, for each $1,000 in Original Principal Amount of Securities
surrendered for conversion, cash and whole shares of Common Stock, if any, equal to the sum of the
Daily Settlement Amounts for each of the 20 VWAP Trading Days during the related Observation
Period,

in each case subject, if applicable, to Section 12.02(c), Section 12.04 and
Section 12.10 hereof. The applicable settlement method for any particular conversion of
Securities (pursuant to clause (i), (ii) or (iii) above) shall be
determined pursuant to Section 12.02(b).

     (b) Prior to the 25th Scheduled Trading Day prior to the Maturity Date, the Company may elect
to repay Securities surrendered for conversion pursuant to clause (i), (ii) or
(iii) of Section 12.02(a) (or, if the Company has made the Net Share Settlement
Election on or prior to the applicable Conversion Date, clause (iii) of
Section 12.02(a)) by providing notice (a “Consideration Notice”) to the converting Holders
through the Trustee (by requesting in writing that the Trustee provide the Consideration Notice) of
the applicable settlement method no later than the second Business Day immediately following the
related Conversion Date or by making the Net Share Settlement Election. If the Consideration
Notice designates settlement pursuant to clause (iii) of Section 12.02(a), it will
state the Specified Dollar Amount. Except as provided in the immediately succeeding paragraph, if
the Company does not provide a Consideration Notice in respect of a conversion and has not made the
Net Settlement Election, conversion of the applicable Securities will be settled pursuant to
clause (i) of Section 12.02(a).

     At any time prior to the 25th Scheduled Trading Day prior to the Maturity Date, if the Company
has not made the Net Share Settlement Election, the Company may deliver a one-time Consideration
Notice to the Holders designating the settlement method (clause (i), (ii) or
(iii) of Section 12.02(a) or, if the Company has made the Net Share Settlement
Election, clause (iii) of Section 12.02(a)) for all conversions that occur on or
after the 25th Scheduled Trading Day prior to such Maturity Date. If the Consideration Notice
designates settlement pursuant to clause (iii) of Section 12.02(a), it will state
the Specified Dollar Amount. For conversions that occur on or after the 25th Scheduled Trading Day
prior to the Maturity Date, if the Company has not
delivered the one-time Consideration Notice referred to in this Section 12.02(b) and
has not made the Net Share Settlement Election, conversion of the Securities will be settled as
though

85

 

the Company had made the Net Share Settlement Election with a Specified Dollar Amount equal
to the Accreted Principal Amount of such Securities as of the Maturity Date of the Securities.

     At any time prior to the 25th Scheduled Trading Day prior to the Maturity Date, the Company
may deliver a one-time irrevocable notice to the Holders electing to settle all conversions of the
Securities from the date of such notice pursuant to clause (iii) of
Section 12.02(a) (the “Net Share Settlement Election”). If the Company has made the Net
Share Settlement Election, the notice of such Net Share Settlement Election shall state the
Specified Dollar Amount applicable to all conversions of such Securities, which shall be equal to
the Accreted Principal Amount of such Securities as of the Conversion Date; provided, however that
the Specified Dollar Amount applicable to all conversions of such Securities converted on or after
the 25th Scheduled Trading Day prior to the Maturity Date shall be the Accreted Principal Amount of
such Securities as of the Maturity Date. The Net Share Settlement Election is in the sole
discretion of the Company and does not require the consent of any Holder. Upon making the Net
Share Settlement Election, the Company promptly will issue a press release and post such
information on its website, or otherwise publicly disclose such information, and will provide
written notice to the Holders in the manner contemplated by this Indenture, including through the
facilities of the Depository.

     The Company will settle all conversions by Holders converting on the same Trading Day in the
same manner. Except for all conversions that occur on or after the 25th Scheduled Trading Day
prior to the Maturity Date or, if earlier, after the Company makes the Net Share Settlement
Election, the Company will have no obligation to repay any Securities tendered for conversion on
different Trading Days in the same manner.

     (c) Before any Holder of a Security shall be entitled to convert the same as set forth above,
such Holder shall (1) in the case of a Global Security, 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 pursuant to Section 12.02(i)
and, if required, pay all taxes or duties, if any, in connection therewith, and (2) in the case of
a Security issued in certificated form, (A) complete and manually sign and deliver an irrevocable
written notice to the Conversion Agent in the form set forth under Section 2.05 (or a
facsimile thereof) (a “Notice of Conversion”) at the office of the Conversion Agent and shall state
in writing therein the Original Principal Amount of Securities 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, if any, to be delivered upon settlement of the Conversion Obligation to be
registered, (B) surrender such Securities, duly endorsed to the Company or in blank (and
accompanied by appropriate endorsement and transfer documents), at the office of the Conversion
Agent, (C) if required, pay all taxes or duties (including transfer taxes), if any, in connection
therewith and (D) 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 12.02(i).

     No Notice of Conversion with respect to any Securities may be tendered by a Holder thereof if
such Holder has also tendered an Optional Put Repurchase Notice or a Fundamental Change Repurchase
Notice and not validly withdrawn such Optional Put Repurchase Notice or
Fundamental Change Repurchase Notice in accordance with the applicable provisions of
Section 11.08 or Section 11.09.

86

 

     If more than one Security shall be surrendered for conversion at one time by the same Holder,
the Conversion Obligation with respect to such Securities, if any, that shall be payable upon
conversion shall be computed on the basis of the aggregate Original Principal Amount of the
Securities (or specified portions thereof to the extent permitted thereby) so surrendered.

     At any time on or before the close of business on the Trading Day following receipt by the
Company of a Holder’s Notice of Conversion, the Company shall provide notice (“Notice of Jones Act
Restrictions”) to the converting Holder whether any Jones Act Restrictions would apply (or are
reasonably likely to apply) to any shares of Common Stock (after giving effect to the Company’s
election to satisfy its Conversion Obligation in cash or a combination of cash and shares of Common
Stock pursuant to Section 12.02(a)), to be issued to the converting Holder, based on
(i) the assumption that such converting Holder is not a U.S. Citizen and (ii) the current ownership
of outstanding Common Stock by Persons who are not U.S. Citizens. Following the last VWAP Trading
Day of the Final Observation Period but before the close of business on the VWAP Trading Day
immediately following the last VWAP Trading Day of the Final Observation Period, the Company will
provide a single Notice of Jones Act Restrictions (in lieu of individual notices) applicable to any
Conversion Date occurring on or after the 25th Scheduled Trading Day prior to the Maturity Date. If
the Company provides a Notice of Jones Act Restrictions to a converting Holder, such Holder may
retract their Conversion Notice at any time during the five Business Day period immediately
following the date of such notice (the “Conversion Retraction Period”). A converting Holder’s
Notice of Conversion shall be irrevocable unless the Company provides a Notice of Jones Act
Restrictions to such converting Holder, in which case such Notice of Conversion shall be
irrevocable except during the Conversion Retraction Period.

     (d) Delivery of the amounts owing in satisfaction of the Conversion Obligation shall be made
by the Company in no event later than the date specified in subsection (a) or (b),
as applicable, of this Section 12.02. The Company shall make such delivery by paying the
cash amount owed, if any, to the Holder of the Security surrendered for conversion, or such
Holder’s nominee or nominees, and/or by issuing, or causing to be issued, and delivering to such
Holder, or such Holder’s nominee or nominees, certificates or a book-entry transfer through the
Depositary for the number of full shares of Common Stock, if any, to which such Holder shall be
entitled as part of such Conversion Obligation (together with any cash in lieu of fractional
shares).

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

     (f) If a Holder submits a Security for conversion, the Company shall pay all documentary,
stamp or similar issue or transfer taxes, if any, which may be imposed by the United States or any
political subdivision thereof or taxing authority thereof or therein with
respect to the issuance of shares of Common Stock, if any, upon the conversion. However, the
Holder and not the Company shall pay any such tax which is due because the Holder requests any
shares of Common Stock to be issued in a name other than the Holder’s name. The

87

 

Company 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 Company receives a sum sufficient to pay any tax which will be due
because the shares are to be issued in a name other than the Holder’s name. Nothing herein shall
preclude any tax withholding required by law or regulations. The Company will not be required to
make any payment with respect to any other tax, assessment or governmental charge imposed by any
other government or any political subdivision or taxing authority thereof (including, without
limitation, any tax, assessment or governmental charge imposed on the income or gain of a Holder or
Beneficial Owner).

     (g) Except as provided in Section 12.05, no adjustment shall be made for dividends on
any shares issued upon the conversion of any Security as provided in this Article 12.

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

     (i) Upon conversion, a Holder shall not receive any separate cash payment for accrued and
unpaid Interest except as set forth below. The Company’s settlement of the Conversion Obligation
as described above shall be deemed to satisfy its obligation to pay the Accreted Principal Amount
of the Securities and accrued and unpaid Interest to, but not including, the Conversion Date. As a
result, accrued and unpaid Interest on the Securities to, but not including, the Conversion Date
and Accreted Principal Amount in excess of the $1,000 Original Principal Amount of such Securities
shall be deemed to be paid in full rather than cancelled, extinguished or forfeited.
Notwithstanding the preceding two sentences, if Securities are converted after 5:00 p.m., New York
City time, on a Regular Record Date, Holders of such Securities as of 5:00 p.m., New York City
time, on such Regular Record Date shall receive the Interest payable on such Securities on the
corresponding Interest Payment Date notwithstanding the conversion. Securities surrendered for
conversion during the period from and after 5:00 p.m., New York City time, on any Regular Record
Date to 9:00 a.m., New York City time, on the immediately following Interest Payment Date must be
accompanied by payment of an amount in cash equal to the Interest payable, on such Interest Payment
Date, on the Securities so converted; provided, however, that no such payment need be made (i) if
the Company has specified a Fundamental Change Repurchase Date that is after a Regular Record Date
and prior to the next Scheduled Trading Day following the corresponding Interest Payment Date; or
(ii) to the extent of any overdue Interest, if any overdue Interest remains unpaid at the time of
conversion with respect to such Security. Except as described above, no payment or adjustment
shall be made for accrued Interest on converted Securities. The Company shall not be required to
convert any Securities that are surrendered for conversion without payment of Interest as required
by this Section 12.02(i). The Conversion Rate will not be adjusted for accrued and unpaid
Interest or accreted principal in excess of the $1,000 Original Principal Amount of the Securities.

     (j) Notwithstanding any of the foregoing to the contrary, in lieu of settling the Conversion
Obligation in the manner set forth in Section 12.02(a) above, the Company may elect (the
“Exchange Election”) to direct the Conversion Agent in writing to surrender, on or prior to the
second Business Day following the Conversion Date, Securities surrendered for conversion

88

 

to a
financial institution designated by the Company (the “Financial Institution”) for exchange in lieu
of conversion. In order to accept any Securities surrendered for conversion, the Financial
Institution must agree to timely deliver, in exchange for such Securities, the shares of Common
Stock and/or cash which would otherwise be due upon conversion as, and at the times, set forth in
Section 12.02(a) (the “Conversion Consideration”). If the Company makes the Exchange
Election, the Company will, by 5:00 p.m., New York City time, on the second Business Day following
the relevant Conversion Date, notify Holders surrendering Securities for conversion that the
Company has made the Exchange Election and will notify the Financial Institution of the Conversion
Consideration to be delivered pursuant to Section 12.02(a) and (b) and the relevant
deadline for delivery of the Conversion Consideration. Any Securities exchanged by the Financial
Institution will remain Outstanding. If the Financial Institution agrees to accept any Securities
for exchange but does not timely deliver the related Conversion Consideration, or if such Financial
Institution does not accept such Securities for exchange, the Company will deliver the Conversion
Consideration as if the Company had not made the Exchange Election.

     Section 12.03. Restrictions on Conversion Rights.

     Notwithstanding anything in this Indenture to the contrary, no Holder who cannot establish to
the Company’s reasonable satisfaction that it (or, if not the Holder, the Person that the Holder
has designated to receive the Common Stock issuable upon conversion of the Securities) is a U.S.
Citizen (i) may exercise any conversion right with respect to the Securities to the extent that the
receipt of the Common Stock, if any, deliverable upon conversion of the Securities (after giving
effect to the Company’s election to satisfy its Conversion Obligation in cash or a combination of
cash and shares of Common Stock pursuant to Section 12.02(a)) would cause such Person, or
any Person whose ownership position would be aggregated with that of such Person under applicable
Maritime Laws, to exceed 4.9% of the outstanding Common Stock or (ii) shall receive any shares of
Common Stock upon conversion of the Securities to the extent such shares would constitute Excess
Shares if they were issued. Settlement of any shares of Common Stock that would constitute Excess
Shares if they were issued shall be suspended until such time, if any, that such shares would not
constitute Excess Shares if they were issued.

     Notwithstanding anything in this Indenture to the contrary, a Holder (or, if not the Holder,
the Person that the Holder has designated to receive the shares of Common Stock issuable upon
conversion of the Securities) shall not become the record or beneficial owner of any shares of
Common Stock the settlement of which is suspended as described above, or otherwise have any rights
as a holder of Common Stock with respect to such shares, until such time, if any, as such shares
would not constitute Excess Shares if they were issued.

     Section 12.04. Fractions of Shares.

     No fractional shares of Common Stock shall be issued upon conversion of any Security or
Securities. If more than one Security shall be surrendered for conversion at one time by the same
Holder, the number of full shares which shall be issuable upon conversion thereof shall be computed
on the basis of the aggregate Original Principal Amount of the Securities (or specified portions
thereof) so surrendered. Instead of any fractional share of Common Stock that would otherwise be
issuable upon conversion of any Security or Securities (or specified portions thereof), the Company
shall calculate and pay a cash adjustment in respect of such fraction

89

 

(calculated to the nearest
1/100th of a share) based on (x) the Daily VWAP on the last VWAP Trading Day of the applicable
Observation Period in the case of conversions settled in accordance with clause (iii) of
Section 12.02(a) above and (y) the Last Reported Sale Price of the Common Stock on the
Conversion Date (or, if the Conversion Date is not a Trading Day, the next following Trading Day)
in the case of conversions settled in accordance with clause (i) of
Section 12.02(a) above.

     Section 12.05. Adjustment of Conversion Rate.

     The Conversion Rate shall be adjusted from time to time by the Company as follows; provided
that the Company shall not make any adjustments to the Conversion Rate if Holders participate (as a
result of holding the Securities) at the same time as holders of Common Stock participate, in any
of the transactions described below as if such Holders held a number of shares of Common Stock
equal to the then-applicable Conversion Rate, multiplied by the Original Principal Amount of
Securities held by such Holders divided by $1,000, without having to convert their Securities:

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

	 	 	 	 	 	 	 
	 

	 	CR’ 
=  CR 0  X
	 	OS’
	 	 
	 

	 	 	 	 	 
	 

	 	 	OS0	 	 

where,

     CR0 = the Conversion Rate in effect as of the close of business on the day
immediately preceding the Ex Date for such dividend or distribution, or the effective date of such
share split or combination, as the case may be;

     CR’ = the Conversion Rate in effect immediately after the opening of business on the Ex Date
for such dividend or distribution, or the effective date of such share split or combination, as the
case may be;

     OS0 = the number of shares of Common Stock outstanding as of the close of
business on the day immediately preceding the Ex Date for such dividend or distribution or on the
effective date of such share split or combination, as the case may be; and

     OS’ = the number of shares of Common Stock that would be outstanding immediately after the
opening of business on the Ex Date for such dividend or distribution after giving effect to such
dividend or distribution or immediately after the effective date of such share split or combination
after giving effect to such share split or combination, as the case may be.

     Any adjustment made pursuant to this subsection (a) shall become effective on (x) the
Ex Date for such dividend or distribution, or (y) the date on which such split or combination
becomes effective, as applicable. If any dividend or distribution of the type described in this
Section 12.05(a) is declared but not paid or made, the new Conversion Rate shall be
readjusted to

90

 

the Conversion Rate that would be in effect if such dividend or distribution had not
been declared.

     (b) If the Company distributes to all or substantially all holders of Common Stock any rights
or warrants (other than, as described below, rights distributed pursuant to a stockholders’ rights
plan) entitling them for a period of not more than 60 calendar days after the date of such
distribution to subscribe for or purchase shares of Common Stock at a price per share less than the
average of the Last Reported Sale Prices of the Common Stock for the 10 consecutive Trading Day
period immediately preceding the declaration date for such distribution, the Conversion Rate shall
be adjusted based on the following formula:

	 	 	 	 	 	 	 
	 

	 	CR’ =  CR 0   X
	 	OS0 + X
	 	 
	 

	 	 	 	 	 
	 

	 	 	OS0 + Y	 	 

where,

     CR0 = the Conversion Rate in effect as of the close of business on the day
immediately preceding the Ex Date for such distribution;

     CR’ = the Conversion Rate in effect immediately after the opening of business on the Ex Date
for such distribution;

     OS0 = the number of shares of Common Stock outstanding as of the close of
business on the day immediately preceding the Ex Date for such distribution;

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

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

     For purposes of this subsection (b), in determining whether any rights or warrants
entitle the holders to subscribe for or purchase shares of Common Stock at less than such average
of the Last Reported Sale Prices of the Common Stock for the 10 consecutive Trading Day period
immediately preceding the declaration date for such distribution, and in determining the aggregate
exercise or conversion price payable for such shares of Common Stock, there shall be taken into
account any consideration received by the Company for such rights or warrants and
any amount payable on exercise or conversion thereof, with the value of such consideration, if
other than cash, to be determined by the Board of Directors. If any right or warrant described in
this subsection (b) is not exercised or converted prior to the expiration of the
exercisability or convertibility thereof, the new Conversion Rate shall be readjusted to the
Conversion Rate that would have been in effect if such right or warrant had not been issued.

     (c) If the Company distributes to shares of any class of Capital Stock of the Company,
evidences of its indebtedness or other assets or property of the Company to all or substantially
all holders of Common Stock (but excluding dividends or distributions referred to

91

 

in
subsection (a) or (b) of this Section 12.05, dividends or distributions
paid exclusively in cash referred to in subsection (d) of this Section 12.05, and
distributions described below in this subsection (c) with respect to Spin-Offs) (any of
such shares of Capital Stock, indebtedness or other asset or property hereinafter in this
subsection (c) called the “Distributed Property”), then, in each such case the Conversion
Rate shall be adjusted based on the following formula:

	 	 	 	 	 	 	 
	 

	 	CR’ =  CR 0  X
	 	SP0
	 	 
	 

	 	 	 	 	 
	 

	 	 	SP0 - FMV	 	 

where,

     CR0 = the Conversion Rate in effect as of the close of business on the day
immediately preceding the Ex Date for such distribution;

     CR’ = the Conversion Rate in effect immediately after the opening of business on the Ex Date
for such distribution;

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

     FMV = the Fair Market Value, as determined by the Board of Directors, of the shares of
Capital Stock, evidences of indebtedness, assets or property distributed with respect to each
outstanding share of Common Stock on the Ex Date for such distribution.

     If “FMV” as set forth above is equal to or greater than “SP0” as set forth
above,
in lieu of the foregoing adjustment, adequate provision shall be made so that each Holder has the
right to receive, for each $1,000 in Original Principal Amount of Securities, the amount of
Distributed Property such Holder would have received had such Holder owned a number of shares of
Common Stock equal to the Conversion Rate on the Ex Date for such distribution, without being
required to convert the Securities.

     With respect to an adjustment pursuant to this subsection (c) where there has been a
payment of a dividend or other distribution on the Common Stock in shares of Capital Stock of any
class or series, or similar equity interest, of or relating to a Subsidiary or other Company
business unit (a “Spin-Off”), the Conversion Rate in effect immediately before 5:00 p.m., New York
City time, on the 10th Trading Day immediately following the effective date of the Spin-Off shall
be increased based on the following formula:

	 	 	 	 	 	 	 
	 

	 	CR’ = CR 0  X
	 	FMV0 + MP0
	 	 
	 

	 	 	 	 	 
	 

	 	 	MP0	 	 

where,

     CR0 = the Conversion Rate in effect immediately before 5:00 p.m., New York City
time, on the 10th Trading Day immediately following the effective date of the Spin-Off;

92

 

     CR’ = the Conversion Rate in effect immediately after 5:00 p.m., New York City time, on the
10th Trading Day immediately following 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 Common Stock applicable to one share of Common
Stock over the first 10 consecutive Trading Day period beginning on, and including, the Trading Day
immediately following the effective date of the Spin-Off; and

     MP0 = the average of the Last Reported Sale Prices per share of the Common Stock
over the first 10 consecutive Trading Day period beginning on, and including, the Trading Day
immediately following the effective date of the Spin-Off.

     Such adjustment shall occur as of 5:00 p.m., New York City time, on the 10th Trading Day
immediately following the effective date of the Spin-Off; provided that in respect of any
conversion within such 10 Trading Day period, references in this subsection (c) with
respect to the Spin-Off to 10 Trading Days shall be deemed replaced with such lesser number of
Trading Days as have elapsed from, and excluding, the effective date of such Spin-Off to, and
including, the Conversion Date in determining the applicable Conversion Rate.

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

     Rights or warrants distributed by the Company to all holders of Common Stock, entitling the
holders thereof to subscribe for or purchase shares of the Company’s Capital Stock, including
Common Stock (either initially or under certain circumstances), which rights or warrants, until the
occurrence of a specified event or events (“Trigger Event”): (i) are deemed to be transferred with
such shares of Common Stock; (ii) are not exercisable; and (iii) are also issued in respect of
future issuances of Common Stock, shall be deemed not to have been distributed for purposes of this
Section 12.05 (and no adjustment to the Conversion Rate under this Section 12.05
shall be required) until the occurrence of the earliest Trigger Event, whereupon such rights and
warrants shall be deemed to have been distributed and an appropriate adjustment (if any is
required) to the Conversion Rate shall be made under this subsection (c). If any such
rights or warrants are subject to events, upon the occurrence of which such rights or warrants
become exercisable to purchase different securities, evidences of indebtedness or other assets,
then the date of the occurrence of any and each such event shall be deemed to be the date of
distribution and record date with respect to new rights or warrants with such rights (and a
termination or expiration of the existing rights or warrants without exercise by any of the holders
thereof). In addition, in the event of any distribution (or deemed distribution) of rights or
warrants, or any Trigger Event or other event (of the type described in the preceding sentence)
with respect thereto that was
counted for purposes of calculating a distribution amount for which an adjustment to the
Conversion Rate under this Section 12.05 was made, (1) in the case of any such rights or
warrants that shall all have been redeemed or repurchased without exercise by any holders thereof,
the Conversion Rate shall be readjusted upon such final redemption or repurchase to give effect to
such distribution or Trigger Event, as the case may be, as though it were a cash distribution,
equal to the per share redemption or repurchase price received by a holder or holders of Common
Stock with respect to such rights or warrants (assuming such holder had

93

 

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

     For purposes of this subsection (c) and subsections (a) and (b) of
this Section 12.05, any dividend or distribution to which this subsection (c) is
applicable that also includes shares of Common Stock to which subsection (a) of this
Section 12.05 applies or rights or warrants to subscribe for or purchase shares of Common
Stock to which subsection (a) or (b) of this Section 12.05 applies (or
both), shall be deemed instead to be (1) a dividend or distribution of the evidences of
indebtedness, assets or shares of Capital Stock other than such shares of Common Stock or rights or
warrants, to which this subsection (c) applies (and any Conversion Rate adjustment required
by this subsection (c) with respect to such dividend or distribution shall then be made)
immediately followed by (2) a dividend or distribution of such shares of Common Stock or such
rights or warrants (and any further Conversion Rate adjustment required by subsections (a) and (b)
of this Section 12.05 with respect to such dividend or distribution shall then be made),
except (A) the Ex Date of such dividend or distribution shall under this subsection (c) be
substituted as the “Ex Date” within the meaning of subsection (a) and subsection
(b) and (B) any shares of Common Stock included in such dividend or distribution shall not be
deemed “outstanding as of the close of business on the day immediately preceding the Ex Date for
such dividend or distribution, or the effective date of such share split or combination, as the
case may be” within the meaning of subsection (a) or “outstanding as of the close of
business on the day immediately preceding the Ex Date for such distribution” within the meaning of
subsection (b).

     (d) If the Company shall pay any cash dividends or distributions to all or substantially all
holders of its Common Stock, the Conversion Rate shall be adjusted based on the following formula:

	 	 	 	 	 	 	 
	 

	 	CR’ = CR 0  X
	 	SP0
	 	 
	 

	 	 	 	 	 
	 

	 	 	SP0  - C	 	 

where,

     CR0 = the Conversion Rate in effect as of the close of business on the day
immediately preceding the Ex Date for such dividend or distribution;

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

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

     C = the cash amount per share of Common Stock of the dividend or distribution.

94

 

     If the cash amount so distributed applicable to one share of the Common Stock is equal to or
greater than “SP0” as set forth above, in lieu of the foregoing adjustment, adequate
provision shall be made so that each Holder shall receive on the date on which such cash dividend
is distributed to holders of Common Stock, for each $1,000 in Original Principal Amount of
Securities, the amount of cash such Holder would have received had such Holder owned a number of
shares equal to the Conversion Rate on the Ex Date for such distribution, without being required to
convert the Securities.

     If any such dividend or distribution is declared but not so paid or made, the new Conversion
Rate shall be readjusted to be the Conversion Rate that would then be in effect if such dividend or
distribution had not been declared.

     For the avoidance of doubt, for purposes of this subsection (d), in the event of any
reclassification of the Common Stock, as a result of which the Securities become convertible into
more than one class of Common Stock, if an adjustment to the Conversion Rate is required pursuant
to this subsection (d), references in this Section 12.05 to one share of Common
Stock or Last Reported Sale Price of one share of Common Stock shall be deemed to refer to a unit
or to the price of a unit consisting of the number of shares of each class of Common Stock into
which the Securities are then convertible equal to the numbers of shares of such class issued in
respect of one share of Common Stock in such reclassification. The above provisions of this
paragraph shall similarly apply to successive reclassifications.

     (e) If the Company or any of its Subsidiaries make a payment in respect of a tender offer or
exchange offer for Common Stock, to the extent that the cash and value of any other consideration
included in the payment per share of Common Stock exceeds the average of the Last Reported Sale
Prices of the Common Stock for the 10 consecutive Trading Day period beginning on, and including,
the Trading Day next succeeding the date on which such tender or exchange offer expires, the
Conversion Rate shall be increased based on the following formula:

	 	 	 	 	 	 	 
	 

	 	CR’ = CR 0  X
	 	AC + (SP’ X OS’)
	 	 
	 

	 	 	 	 	 
	 

	 	 	OS0 X SP’	 	 

where,

     CR0 = the Conversion Rate in effect at the close of business on the last Trading
Day of the 10 consecutive Trading Day period beginning on, and including, the Trading Day next
succeeding the date such tender or exchange offer expires;

     CR’ = the Conversion Rate in effect on the Business Day following the last Trading Day of
the 10 consecutive Trading Day period beginning on, 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 purchased in such tender or exchange offer;

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

95

 

     OS’ = the number of shares of Common Stock outstanding immediately after the expiration of
such tender or exchange offer (after giving effect to the purchase of shares pursuant to such
tender offer or exchange offer); and

     SP’ = the average of the Last Reported Sale Prices of Common Stock for the 10 consecutive
Trading Day period beginning on, and including, the Trading Day next succeeding the date such
tender or exchange offer expires.

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

     (f) No adjustment to the Conversion Rate shall be made if the application of any of the
formulas set forth in this Section 12.05 (other than in respect of a share combination)
would result in a decrease in the Conversion Rate.

     In addition to any increases to the Conversion Rate required by subsections (a),
(b), (c), (d) and (e) of this Section 12.05, and to the
extent permitted by applicable law and the rules of the NASDAQ Global Select Market or any other
securities exchange on which the Common Stock is then listed, the Company from time to time may
increase the Conversion Rate by any amount for a period of at least 20 days if the Board of
Directors determines that such increase would be in the Company’s best interest, which
determination shall be conclusive. Whenever the Company decides to increase the Conversion Rate
pursuant to the preceding sentence, the Company shall notify the Holders and the Trustee of the
increase at least 15 calendar 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 and otherwise comply with applicable law. In addition, the Company may also (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 any dividend or distribution of shares
(or rights to acquire shares) or similar event.

     (g) Without limiting the foregoing, except as otherwise provided in this Section 12.05
or in Section 12.01(e), no adjustment to the Conversion Rate will be made:

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

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

96

 

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

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

          (v) for accrued and unpaid Interest;

          (vi) for accreted principal in excess of the $1,000 Original Principal Amount; or

          (vii) as a result of a tender offer solely to holders of fewer than 100 shares of the Common
Stock.

     (h) All calculations and other determinations under this Article shall be made by the Company
and shall be made to the nearest cent or to the nearest one-ten thousandth (1/10,000) of a share,
as the case may be. No adjustment to the Conversion Rate will be required unless the adjustment
would require an increase or decrease of at least 1% of the Conversion Rate. However, the Company
will carry forward any adjustments that are less than 1% of the Conversion Rate that the Company
elects not to make and take them into account upon the earlier of (1) any conversion of Securities
(2) each VWAP Trading Day during the period beginning on, and including, the 22nd Scheduled Trading
Day prior to the Maturity Date, and (3) such time as all adjustments that have not been made prior
thereto would have the effect of adjusting the Conversion Rate by at least 1%.

     (i) For purposes of this Section 12.05, the number of shares of Common Stock at any
time outstanding shall not include shares held in the treasury of the Company but shall include
shares issuable in respect of scrip certificates issued in lieu of fractions of shares of Common
Stock.

     (j) With respect to a conversion of Securities pursuant to this Article, at and after 5:00
p.m., New York City time, on the last VWAP Trading Day of the related Observation Period or, if
there is no Observation Period, at and after 5:00 p.m., New York City time, on the Conversion Date
(such Last VWAP Trading Day or Conversion Date, a “Relevant Date”), the Person in whose name any
certificate representing any shares of Common Stock issuable upon such conversion is registered
shall be treated as a stockholder of record of the Company on such Relevant Date; provided,
however, that if any such shares of Common Stock constitute Additional Shares, then the Relevant
Date with respect to such shares that constitute Additional Shares shall instead be deemed to be
the later of (i) the last VWAP Trading Day of the related Observation Period and (ii) the effective
date of the Make-Whole Fundamental Change resulting in the Additional Shares. On and after the
Conversion Date with respect to a conversion of Securities pursuant hereto, all rights of the
Holders of such Securities shall terminate, other than the right to receive the consideration
deliverable upon conversion of such Securities as provided
herein. A Holder of a Security is not entitled, as such, to any rights of a holder of Common
Stock until, if such Holder converts such Security and is entitled pursuant hereto to receive
shares of Common Stock in respect of such conversion, 5:00 p.m., New York City time, on the
Relevant Date or respective Relevant Dates, as the case may be, with respect to such conversion.

     (k) To the extent that the Company has a stockholders’ rights plan in effect upon conversion
of the Securities into Common Stock, the Holder so converting will receive, in addition to any
Common Stock deliverable and in lieu of any adjustment to the Conversion Rate, the rights under
such rights plan, unless prior to any conversion, the rights have separated from Common Stock, in
which case the Conversion Rate will be adjusted at the time of separation as if the Company
distributed to all holders of Common Stock, shares of the Company’s Capital Stock, evidences of
indebtedness or assets as described in Section 12.05(c), subject to readjustment in the
event of expiration, termination or redemption of such rights. A further adjustment will occur as
described in Section 12.05(d), if such rights become exercisable to purchase different
securities, evidences of indebtedness or assets, subject to readjustment in the event of the
expiration, termination or redemption of such rights. If the Company’s stockholder rights plan
existing at the date of this Indenture is terminated and the Company at any time thereafter
implements a new or replacement stockholder rights plan, no adjustment in the Conversion Rate will
be required upon issuance of rights under such plan.

     (l) Whenever any provision of this Article requires a calculation of Last Reported Sale Prices
or Daily VWAP over a span of multiple days, the Company shall make appropriate adjustments
(determined in good faith by the Board of Directors) to account for any adjustment to the
Conversion Rate that becomes effective, or any event requiring an adjustment to the Conversion Rate
where the Ex Date of the event occurs, at any time during the period from which such calculation is
to be calculated; provided that such adjustments shall only be made relating to days prior to the
date that the adjustment to the Conversion Rate becomes effective.

     Section 12.06. Notice of Adjustments of Conversion Rate.

     Whenever the Conversion Rate is adjusted as herein provided:

     (a) the Company shall compute the adjusted Conversion Rate in accordance with
Section 12.05 and shall prepare a certificate signed by an Officer of the Company setting
forth the adjusted Conversion Rate and showing in reasonable detail the facts upon which such
adjustment is based, and such certificate shall promptly be filed with the Trustee and with each
Conversion Agent (if other than the Trustee); and

     (b) upon each such adjustment, a notice stating that the Conversion Rate has been adjusted and
setting forth the adjusted Conversion Rate shall be required, and such notice shall be provided by
the Company to all Holders in accordance with Section 1.06.

     Neither the Trustee nor any Conversion Agent shall be under any duty or responsibility with
respect to any such certificate or the information and calculations contained therein, except to
exhibit the same to any Holder of Securities desiring inspection thereof at its office during
normal business hours.

     Section 12.07. Company to Reserve Common Stock.

     The Company shall at all times reserve and keep available, free from preemptive rights, out of
its authorized but unissued Common Stock, for the purpose of effecting the conversion of
Securities, the full number of shares of Common Stock then issuable upon the conversion of all
Outstanding Securities.

98

 

     Section 12.08. Certain Covenants.

     Before taking any action which would cause an adjustment reducing the Conversion Rate below
the then par value, if any, of the shares of Common Stock issuable upon conversion of the
Securities, the Company shall take all corporate action which it reasonably determines may be
necessary in order that the Company may validly and legally issue shares of such Common Stock at
such adjusted Conversion Rate. Notwithstanding any other provision of this Article, in the event
of any adjustment or increase to the Conversion Rate that would result in the Securities, in the
aggregate, becoming convertible into a number of shares of Common Stock that exceeds the number
permitted by applicable rules or listing standards of the Nasdaq Global Select Market or of any
other securities exchange on which the Common Stock is then listed or traded without obtaining
stockholder approval of such issuance, the Company shall, at its option, either (i) obtain the
approval of its stockholders regarding the issuance of such Common Stock or (ii) elect to deliver
cash, in accordance with Section 12.02, in lieu of any shares of Common Stock otherwise
deliverable in excess of the number permitted to be delivered under such rules or listing
standards.

     The Company covenants that all shares of Common Stock issued upon conversion of Securities
shall be fully paid and non-assessable by the Company and free from liens created by the Company.

     The Company further covenants that if at any time the Common Stock shall be listed for trading
on any other national securities exchange the Company shall, if permitted and required by the rules
of such exchange, list and keep listed, so long as the Common Stock shall be so listed on such
exchange, all Common Stock issuable upon conversion of the Securities.

     Section 12.09. Cancellation of Converted Securities.

     All Securities surrendered for conversion shall, if surrendered to the Company or any Paying
Agent or any Security Registrar, be surrendered to the Trustee and promptly cancelled by it in
accordance with Section 3.13.

     Section 12.10. Provision in Case of Effect of Reclassification, Consolidation, Merger or Sale.

     If there shall occur (i) any Fundamental Change described in clause (2) of the
definition of Fundamental Change, (ii) any reclassification of Common Stock (other than a change in
par value, or from par value to no par value, or from no par value to par value, or as a result of
a split, subdivision or combination), (iii) any consolidation, binding share exchange,
recapitalization, reclassification, merger, combination or other similar event, or (iv) any sale or
conveyance of all or substantially all of the property and assets of the Company to any other
Person, in each case as a result of which holders of Common Stock shall be entitled to receive
cash, securities or other property or assets with respect to or in exchange for their shares of
Common Stock (any such event described in clauses (i) through (iv) a “Merger
Event”), then the Company or the successor or purchasing Person, as the case may be, shall execute
with the Trustee (subject to the Trustee’s rights as provided herein) a supplemental indenture
(which shall comply with the Trust Indenture Act as in force at the date of execution of such
supplemental indenture if such supplemental

99

 

indenture is then required to so comply) providing for
the conversion and settlement of the Securities as set forth in this Indenture. Such supplemental
indenture shall provide for adjustments which shall be as nearly equivalent as may be practicable
to the adjustments provided for in this Article 12 and the Trustee may conclusively rely on
the determination by the Company of the equivalency of such adjustments. If, in the case of any
Merger Event, the Reference Property includes shares of stock or other securities and assets of a
company other than the successor or purchasing company, as the case may be, in such change of
control, consolidation, binding share exchange, recapitalization, reclassification, merger,
combination, sale or conveyance or Fundamental Change described in clause (2) of the
definition of Fundamental Change, then such supplemental indenture shall also be executed by such
other company and shall contain such additional provisions to protect the interests of the Holders
of the Securities 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 repurchase rights set forth in Article 11.

     In the event a supplemental indenture is executed pursuant to this Section 12.10, the
Company shall promptly file with the Trustee an Officer’s Certificate briefly stating the reasons
therefor, the kind or amount of cash, securities, property or assets that will constitute 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, and the Trustee shall be protected in relying on such Officer’s Certificate; it being
understood that the Trustee shall have no responsibility to determine the correctness of any
provisions contained in any supplemental indenture executed pursuant to this Section 12.10.

     If any securities to be provided for the purpose of conversion of Securities hereunder require
registration with or approval of any governmental authority under any federal or state law before
such securities may be validly issued upon conversion, each supplemental indenture executed
pursuant to this Section 12.10 shall provide that the Company or the successor or the
purchasing Person, as the case may be, or if the Reference Property includes shares of stock or
other securities and assets of a company other than the successor or purchasing company, as the
case may be, then such company, shall use commercially reasonable efforts, to the extent then
permitted by the rules and interpretations of the Commission (or any successor thereto), to secure
such registration or approval in connection with the conversion of Securities.

     Notwithstanding the provisions of Section 12.02 and Section 12.04, and subject
to the provisions of Section 12.01, at the effective time of such Merger Event, the right
to convert each $1,000 in Original Principal Amount of Securities shall be changed to a right to
convert such Securities by reference to the kind and amount of cash, securities, or other property
that a holder of a number of shares of Common Stock equal to the Conversion Rate immediately prior
to such transaction would have owned or been entitled to receive (the “Reference Property”) such
that from and after the effective time of such transaction, a Holder shall be entitled thereafter
to convert its Securities into the same type (and in the same proportion) of Reference Property,
subject to the Company’s right to elect to settle conversions, in whole or in part, in shares of
Common Stock, cash or a combination of cash and shares of Common Stock, provided that if the
Company makes the Net Share Settlement Election, upon conversion, or if the Company elects to
settle all or a portion of Securities surrendered for conversion in cash, Holders will receive
Reference Property as follows: (x) cash up to the aggregate principal portion or sum of the Daily

100

 

Cash Amounts upon any conversion (or, in the case of settlement solely in cash, cash for the sum of
the Daily Conversion Values in respect of such conversion), and (y) in lieu of the shares of Common
Stock otherwise deliverable, Reference Property. The amount of consideration, and, consequently,
Reference Property, Holders receive upon conversion will be based on the Daily Conversion Values of
Reference Property and the applicable Conversion Rate, as described in Section 12.02. For
purposes of determining the constitution of Reference Property, the type and amount of
consideration that a holder of Common Stock would have been entitled to in the case of any Merger
Event that causes the Common Stock to be converted into the right to receive more than a single
type of consideration determined, based in part upon any form of stockholder election, such
consideration will be deemed to be, (i) if holders of a majority of Common Stock affirmatively make
such an election, the weighted average of the types and amounts of consideration received by
holders of Common Stock that affirmatively make such an election, or (ii) if the holders of a
majority of Common Stock do not affirmatively make such an election, the types and amount of
consideration actually received by all holders of Common Stock. The Company shall not become a
party to any such transaction unless its terms are consistent with the preceding. None of the
foregoing provisions shall affect the right of a Holder to convert its Securities in accordance
with the provisions of this Article 12 prior to the effective date of any such Merger
Event. Notwithstanding the foregoing, if the Reference Property is all cash, Holders will be
entitled upon conversion to the consideration that they would have been entitled to receive if they
had held a number of shares of Common Stock equal to the applicable Conversion Rate in effect
immediately prior to such Merger Event and payment upon conversion shall occur on the third
business day after the Conversion Date.

     The Company shall cause notice of the execution of such supplemental indenture to be mailed to
each Holder, at its address appearing on the Security Register provided for in this Indenture,
within 30 calendar days after execution thereof. Failure to deliver such notice shall not affect
the legality or validity of such supplemental indenture.

     The above provisions of this Section 12.10 shall similarly apply to successive Merger
Events.

     Section 12.11. Company Responsible for Making Calculations.

     Except as otherwise provided herein, the Company will be responsible for making all
calculations required under the Securities and this Indenture or in connection with a conversion.
The Company will make these calculations in good faith and, absent manifest error, these
calculations will be final and binding on the Holders. The Company will provide a schedule of such
calculations to each of the Trustee and the Conversion Agent, and each of the Trustee and the
Conversion Agent is entitled to conclusively rely upon the accuracy of such calculations without
independent verification. The Trustee will forward the Company’s calculations to any Holder upon
the written request of such Holder.

101

 

     Section 12.12. Responsibility of Trustee for Conversion Provisions.

     The Trustee and any Conversion Agent shall not at any time be under any duty or responsibility
to any Holder of Securities to determine whether any facts exist which may require any adjustment
of the Conversion Rate, or with respect to the nature or extent of any such adjustment when made,
or with respect to the method employed, herein or in any supplemental indenture provided to be
employed, in making the same, or whether a supplemental indenture need be entered into. Neither
the Trustee nor any Conversion Agent shall be accountable with respect to the validity or value (or
the kind or amount) of any Common Stock, or of any other securities or property or cash, which may
at any time be issued or delivered upon the conversion of any Securities; and it or they do not
make any representation with respect thereto. Neither the Trustee nor any Conversion Agent shall
be responsible for any failure of the Company to make or calculate any cash payment or to issue,
transfer or deliver any shares of Common Stock or share certificates or other securities or
property or cash upon the surrender of any Security for the purpose of conversion; and the Trustee
and any Conversion Agent shall not be responsible for any failure of the Company to comply with any
of the covenants of the Company contained in this Article.

ARTICLE 13

TAXES

     Section 13.01. Tax Treatment of the Securities.

     The Company agrees, and by acceptance of a beneficial ownership interest in the Securities,
each Holder and Beneficial Owner is deemed to have agreed, in the absence of an administrative
determination or judicial ruling to the contrary, for all United States federal income tax
purposes:

     (a) to treat the Securities as debt instruments subject to United States Treasury Regulations
Section 1.1275-4 (the “Contingent Payment Debt Regulations”);

     (b) to treat cash and the fair market value of any Common Stock beneficially received by a
Holder or Beneficial Owner upon conversion of such Security as a contingent payment for purposes of
the Contingent Payment Debt Regulations;

     (c) to accrue interest with respect to the Securities as original issue discount for United
States federal income tax purposes according to the “noncontingent bond method” set forth in
Treasury Regulations Section 1.1275-4(b);

     (d) to be bound by the Company’s application of the Contingent Payment Debt Regulations to the
Securities, including the Company’s determination of the comparable yield and projected payment
schedule, as defined in the Contingent Payment Debt Regulations, with respect to the Securities;
and

     (e) to use such comparable yield and projected payment schedule in determining interest
accruals with respect to such Holder’s or Beneficial Owner’s Securities and in determining
adjustments thereto.

102

 

     A Holder may obtain the issue price, the amount of original issue discount, the issue date,
the comparable yield (which will be treated as the yield to maturity for United States federal
income tax purposes) and the projected payment schedule for United States federal income tax
purposes by submitting a written request to the Company at the following address: Hercules
Offshore, Inc., 9 Greenway Plaza, Suite 2200, Houston, Texas 77046, Attention: Investor Relations.

     Section 13.02. Withholding for Taxes.

     The Company, its agents, its representative or a Financial Institution may withhold from any
payments under or with respect to the Securities any withholding, backup withholding or similar Tax
required to be withheld by law or by the interpretation or administration thereof. Any amounts so
withheld and remitted to the applicable taxing authority will be treated as having been paid to the
applicable Holder or Beneficial Owner for all purposes of the Indenture and the Securities.
